CROSS REFERENCE TO RELATED APPLICATION
This Application is based upon and derives the benefit of Indian Provisional Application Number 202341056424 filed on February 23, 2024, the contents of which are incorporated herein by reference.
TECHNICAL FIELD
[0001] Embodiments of the present disclosure generally relate to medical devices. In particular, the present disclosure relates to a syringe flusher apparatus for expelling a fluid using a plunger push and auto-pull method.
BACKGROUND
[0002] A Liquid flusher is a syringe prefilled with saline water or any other liquids which are administered into a human body. The special use of the liquid flusher is to flush the blockage in the Intravenous sets, Intravenous syringe needles, Intravenous needles and sometimes for cleaning medical needles. These prefilled syringes sometimes are used for injecting medicine in operation theaters and in other situations in multiple volumes.
[0003] Currently, in the Existing systems, the liquid is prefilled in the syringe or cylinder with piston container and the amount of liquid filled is of fixed quantity. Further, the existing liquid flushers are connected to the IV sets or IV needs or any other normal needles which is blocked by at least coagulated blood, mucus and serum. However, the liquid is flushed out manually by pull and push action of the cylinder and piston of the syringe respectively, in which the amount of liquid flushed out is un-controllable due to unknown amount of force applied to flush the blockage in the needles. Moreover, the liquid flushers of the existing systems are used for single or multiple flush depending on the individual user’s ability to control the amount of liquid flush.
[0004] However, the existing systems faces many drawbacks. More specifically, the volume of liquid flushed out of the cylinder are controlled exactly nor stopped at a specific volume using existing flushers or cylinder and piston action done manually. In the event if the applied high pressure is too high to flush the liquid from the cylinder, in such case there is no control on the force, speed and volume of the liquid flushed out. Furthermore, the amount of force that exerts on the liquid receiver wall is too high and in case of human body, leads to damage the arteries, veins or tissue of the human body. Moreover, when uncontrolled applied force on the flusher exceeds the connection force of the existing flushers and the receiver tube, the flusher gets disconnected and possibly all the liquid in the flusher spills out and exposes to the environment.
[0005] Therefore, there is a need in the art for improved apparatus and methods to address at least the aforementioned technical problems in the prior arts, by providing a syringe flusher apparatus for expelling a fluid using a plunger push and auto-pull method.
SUMMARY
[0006] This summary is provided to introduce a selection of concepts, in a simple manner, which is further described in the detailed description of the disclosure. This summary is neither intended to identify key or essential inventive concepts of the subject matter nor to determine the scope of the disclosure.
[0007] An aspect of the present disclosure provides a syringe flusher apparatus for expelling a fluid using a plunger push and auto-pull method. The syringe flusher apparatus comprises a barrel body further comprising a primary barrel body with a primary diameter dimension, comprising a reservoir to retain a fluid, in which the primary barrel body may comprise one or more inner barrel arms at a distal end of the reservoir. Further, the barrel body comprises a secondary barrel body with a secondary diameter dimension, coupled to a distal end of the primary barrel body with a fluid communication, in which the secondary barrel body may be configured to eject the fluid from the reservoir. Further, the barrel body comprises one or more spring holders comprising a semi-cylindrical structure, coupled to a proximal end of the primary barrel body, through a thin connecting joint, in which the one or more spring holders may be removably mounted within a proximal end of the reservoir to provide a base support for a spring. In an embodiment, the semi-cylindrical structure may be configured to form a cylindrical structure based on mounting within the proximal end of the reservoir. Further, the syringe flusher apparatus comprises a plunger comprising a plunger shaft further comprising a piston coupled to a piston holder at a distal end of the plunger shaft, in which the plunger shaft may be pressable mounted within the spring via the one or more spring holders. In an embodiment, the piston may be positioned in the one or more inner barrel arms. The syringe flusher apparatus may be configured to receive a primary force applied on the plunger shaft, in which the primary force may correspond to a force applied on the plunger shaft towards the piston. In an embodiment, the spring may be configured to compress based on the primary force. Further, the syringe flusher apparatus may be configured to expel the fluid from the reservoir based on the received primary force. Furthermore, the syringe flusher apparatus may identify if the primary force is removed from the plunger shaft, and may retrieve the plunger shaft to a normal position by auto-pulling the compressed spring, based on the removed primary force. Subsequently, the syringe flusher apparatus may be configured to dynamically transfer the fluid from the primary barrel body to the secondary barrel body, upon retrieving the plunger shaft, in which the piston may be configured to generate a vacuum inside the secondary barrel body to transfer the fluid from the primary barrel body to the secondary barrel body. Furthermore, the syringe flusher apparatus may be configured to re-expel the transferred fluid from the reservoir, based on a subsequent application of the primary force.
[0008] Another aspect of the present disclosure includes a method for expelling a fluid out of a syringe reservoir using plunger push and auto-pull method. The method includes receiving, by a syringe flusher apparatus, a primary force applied on the plunger shaft, in which the primary force may correspond to a force applied on the plunger shaft towards the piston. In an embodiment, the spring may be configured to compress based on the primary force. The method then includes expelling, by the syringe flusher apparatus, a fluid from the reservoir, via the plunger shaft, based on the received primary force. Further, the method includes identifying, by the syringe flusher apparatus, if the primary force is removed from the plunger shaft, and retrieving, by the syringe flusher apparatus, the plunger shaft to a normal position by auto-pulling the compressed spring, based on the removed primary force. Furthermore, the method includes dynamically transferring, by the syringe flusher apparatus, the fluid from a primary barrel body to a secondary barrel body, via one or more inner barrel arms, upon retrieving the plunger shaft, in which the piston may be configured to generate a vacuum inside the secondary barrel body to transfer the fluid from the primary barrel body to the secondary barrel body. Finally, the method includes re-expelling, by the syringe flusher apparatus, the transferred fluid from the reservoir, via the plunger shaft, based on a subsequent application of the primary force.

[0089] FIG. 13 illustrates an isometric view and a front view of the one-way blocker unit 605, in accordance with an embodiment of the present disclosure.
[0090] In an embodiment, the distal end 203 of the barrel body 103 may comprise a one-way blocker unit 605 connected between an exit hole 607 and the exit cylinder 603 of the secondary barrel body 103b, in which the one-way blocker unit 605 may be configured to transmit the fluid from the secondary barrel body 103b to the exit cylinder 603 in one-way direction. In an embodiment, the one-way blocker unit 605 may be configured to terminate the fluid flow from the exit cylinder 603 to the secondary barrel body 103b.
[0091] More specifically, the one-way blocker unit 605 may comprise a circular flexible arm 1301 coupled to a cone 1303, in which the circular flexible arm 1301 may be configured to bend towards the cone 1303 when the fluid (not shown in FIG. 13) exits the secondary barrel body 103b with a specific pressure, in which the specific pressure may correspond to a pressure exerted by the plunger shaft 105a on the fluid.
[0092] For example, as shown in (a) and (b) of FIG. 13, the one-way blocker unit 605 may be inserted into the exit hole 607, in which a diameter dimension of a blocker shaft 1305 may be smaller than the diameter dimension of the exit hole 607, to allow the fluid to pass through the exit hole 607. In other words, the one-way blocker unit 607 may provide the exit for the fluid from the from the secondary barrel body 103b and may stop the return of the fluid from the exit cylinder 603, to the secondary barrel body 103b.
[0093] In an embodiment, the circular flexible arm 1301 may bend towards the cone 1303, when the fluid exits the secondary barrel body 103b with high pressure, which may happen when the pressure is applied by the plunger 105 on the fluid in the secondary barrel body 103b.

[0098] FIG. 15 illustrates a front view of the syringe flusher apparatus 101 comprising an inner barrel starting point 1501, and an inner barrel end point 1503, in accordance with an embodiment of the present disclosure.
[0099] In an embodiment, the main part of the syringe flusher apparatus 101 may include the barrel body 103 housing one or more parts such as the plunger 105, one or more cylindrical piston rings 901, the piston 205, and the one way blocker unit 605. The one-way blocker unit 605 may first be inserted into the exit hole 607, such that the one-way blocker head 1307 may remain in the secondary barrel body 103b, and the flexible circular arm 1301 may remain in the exit cylinder 603.
[00100] In an embodiment, the plunger 105 along with piston 205 may push the fluid out from the secondary barrel body 103b. More specifically, the plunger 105 may first be slided into the spring 207 and may further be slided into the one or more cylindrical piston rings 901 by pushing the plunger 105 into the cylindrical hole 907 of the one or more cylindrical piston rings 901, in which the diameter dimension of the plunger shaft 105a may match with the inner diameter dimension of the cylindrical hole 907, to provide the fluid sealant between the plunger shaft 105a and the one or more piston rings 901. Further, the plunger 105 may be fitted into the piston 205 by pushing the piston holder 701 into the piston hole 1101.
[00101] In case of the non-rubber cylindrical piston 1001, the one or more sliding arms 1009 may be pointed towards the distal end 203 of the barrel body 103, and the plunger 105 may first slide into the inner cylinder 1005 of the non-rubber cylindrical piston 1001 and then the piston holder 701 may slide into the piston 205.
[00102] The plunger 105 with the piston 205 and along with the one or more cylindrical rings 901 may be slided into the secondary barrel body 103b via primary barrel body 103a until the piston 205 reaches an inner barrel starting 1501. In an embodiment, the outer diameter dimension of the piston 205 may match the inner diameter dimension of the secondary barrel body 103b to provide the vacuum sealant between the piston 205 and the secondary barrel body 103b. Furthermore, the outer diameter dimension of the one or more cylindrical piston rings 901 may match the inner diameter dimension of the barrel body 103, to generate the airtight connection between the barrel body 103 and the one or more cylindrical rings 901. At this point before sliding the one or more cylindrical piston rings 901 into the barrel body 103, the barrel body 103 may be filled with required fluid to the required level, and once the barrel body 103b is filled with required fluid, the one or more cylindrical piston rings 901 along with plunger 105 may be slided into the barrel body 103. At this point the both the left spring holder wing 307 and the right springer holder wing 309 may be inward folded by 180 degree towards the center of the barrel body 103 with the thin connecting joint 303 as the center of axis. The one or more locking arms may slide into the finger grip slot 415 when folded 180 degree and may get locked with the finger grip 405. At this point the one or more spring arms 401 of the both the left spring holder wing 307 and the right springer holder wing 309 may form parallel and may provide base support for the spring 207.
[00103] After the left spring holder wing 307 and the right springer holder wing 309 are folded by 180 degrees, the piston 205 may be slided until the piston 205 may reach an inner barrel end point 1503. At this point the spring 207 may be compressed fully between the plunger finger grip 705 and the parallel one or more spring arms 401 .
[00104] When the force is removed on the plunger 105, the spring 207 may expand and push the plunger finger grip 705 away from the proximal end 201, to cause the piston 205 to move from the inner barrel end point 1503 to the inner barrel starting point 1501, where the inward lock 505 may prevent the piston 205 from leaving the secondary barrel body 103b, in which the one-way blocker unit 605 may prevent the fluid or air from exit cylinder 603 to enter the secondary barrel body 103b, and may create a vacuum in the secondary barrel body 103b. This vacuum may be filled by the fluid or air via the gap 503 between the one or more inner barrel arms 501 from the reservoir 305 due to atmospheric pressure, in which the atmospheric pressure may push the one or more cylindrical piston rings 901 towards the secondary barrel body 103b. At this point the syringe flusher apparatus 101 may be loaded to expel the fluid or air out of exit cylinder 603.
[00105] In an embodiment, the syringe flusher apparatus 101 may be connected to the devices such as, for example, but not limited to, Intravenous sets, Intravenous syringe needles, Intravenous needles, and medical needles via a connecting slot (not shown in FIG. 15) of the syringe flusher apparatus 101. In this connection the exit cylinder 603 may be slided sand pushed into devices until the exit cylinder 603 stops further sliding, in which the connecting cylinder 601 may slide over the outer diameter dimension of the devices.
[00106] In case of the devices which may have thread able option for connecting, in such case the syringe flusher apparatus 101 may be connected via a connecting thread (not shown in FIG. 15). The syringe flusher apparatus 101 may also be used with tube and needles cleaning blockage.
[00107] Once the syringe flusher apparatus 101 is connected to the devices, the plunger 105 using the plunger finger grip 705 may be pushed while the finger grip 405 of the barrel body 103 may be pulled, as the pressure may builds up in the secondary barrel body 103b the fluid or the air in the secondary barrel body 103b may leave the exit hole 607 via the one or more grooves 609 and may pushes the flexible circular arm 1301 down words leaving space for the fluid to enter into the exit cylinder 603. Further, the plunger 105 may be pushed until the piston 205 reaches the inner barrel end point 1503. At this point the flexible circular arm 1301 may return back to cove the exit hole 607.
[00108] In an embodiment, the cycle of auto pull by the spring 207 and push and pull of plunger finger grip 705 and the finger grip 405 respectively for expelling the fluid or air from the secondary barrel body 103b may be repeated in multiples of time depending on the amount of liquid or air in the syringe flusher apparatus 101.
[00109] FIG. 16 illustrates a flow chart representation of a method 1600 for expelling a fluid using a plunger push and auto-pull method, in accordance with an embodiment of the present disclosure.
[00110] At step 1601, the method 1600 includes receiving, by the syringe flusher apparatus 101, a primary force applied on the plunger shaft 105a, in which the primary force may correspond to a force applied on the plunger shaft 105a towards the piston 205, in which the spring 207 may be configured to compress based on the primary force.
[00111] At step 1602, the method 1600 includes expelling, by the syringe flusher apparatus 101, a fluid from the reservoir 305, via the plunger shaft 105a, based on the received primary force.
[00112] At step 1603, the method 1600 includes identifying, by the syringe flusher apparatus 101, if the primary force is removed from the plunger shaft 105a.
[00113] At step 1604, the method 1600 includes retrieving, by the syringe flusher apparatus 101, the plunger shaft 105a to a normal position by auto-pulling the compressed spring 207, based on the removed primary force.
[00114] At step 1605, the method 1600 includes dynamically transferring, by the syringe flusher apparatus 101, the fluid from a primary barrel body 103a to a secondary barrel body 103b, via one or more inner barrel arms 501, upon retrieving the plunger shaft 105a, in which the piston 205 may be configured to generate a vacuum inside the secondary barrel body 103b to transfer the fluid from the primary barrel body 103a to the secondary barrel body 103b.
[00115] At step 1606, the method 1600 includes re-expelling, by the syringe flusher apparatus 101, the transferred fluid from the reservoir 305, via the plunger shaft 105a, based on a subsequent application of the primary force.
[00116] The present disclosure overcomes the drawbacks of the existing syringe flushers on patients and the users or the operators of this syringe flusher. In present disclosure, the main part of the syringe flusher apparatus is the barrel which is liquid reservoir designed with two steps of different inner diameter. The bigger diameter of the barrel is a reservoir and the smaller diameter of the barrel is for piston action to flush the liquid in fixed volume. The smaller diameter of the barrel gets filled by fulling the piston till the end of the smaller diameter of the barrel which gets stopped automatically by the lock system part of the smaller diameter arms, at this point the inner barrel fills with liquid from the reservoir due to vacuum created in the inner barrel by the piston and the one-way blocker.
[00117] In the present disclosure, the manual loading of syringe by pulling the plunger may be automated by using spring to push the plunger out wards. This auto load of the inner barrel with liquid from the reservoir makes it easy to flush multiples very fast without causing inconvenience to the patients during the push and pull action while it is connected intravenous syringe or needle or other intravenous connected devices. Further, the auto load of the syringe barrel make it easy to plush the liquid in one had when engaged in multiple task handling. s
