DESC:TECHNICAL FIELD
The model's real-world use is in the field of surgical nursing education, more particularly in relation to a model for teaching esophageal surgical nursing procedures and operating rooms, a subfield of surgical nursing education.
BACKGROUND TECHNIQUE
A training model is crucial for students to practice esophageal surgical operations and understand the involved skills. However, the existing educational system still needs improvement. A more effective curriculum was established to educate students about nursing techniques. Six nursing treatments are performed after esophageal surgery: gastric tube implantation and gastrointestinal decompression, oral care, central venous dressing therapy, cardiopulmonary resuscitation (CPR), and nasal feeding. Patients with esophageal cancer are typically provided with a central venous catheter for intravenous feeding. It is essential for nursing staff to understand the surgery's capabilities before the procedure to prevent injuries or unpleasant experiences. Using a pre-existing model is not practical for teaching the six common nursing procedures involved in esophageal surgery. However, sometimes educating nurses on the human body model is necessary to expand their operational knowledge.
It was discovered by the inventor that the current invention model does not address the following deficiencies that are associated with the current state of the art:
(1)There is a strong friction force that makes removing and storing the traditional model of the torso, arm, and head used to teach esophageal surgical techniques problematic;
(2)The conventional model for teaching esophageal surgical nursing procedures will become increasingly worn-out with time since it does not have a wear-resistant quality;
(3)Under the traditional model for teaching esophageal surgical nursing procedures, it is common practice to drain the waste liquid directly from the oesophagus without collecting it collectively, which then makes cleaning a future issue.
INVENTION MODEL CONTENT
The current innovation aims to address the issue of high friction during the connection between the torso, arm, and head, which makes it difficult to disassemble and store the components. The torso and arm mannequin, designed with wear-resistant layers and waste fluids at the bottom, allows for teaching esophageal surgical nursing procedures. The mannequin features an oesophagus permanently attached to the top of the trunk, arms on both sides, and a head on top. An auxiliary disassembly and installation structure is provided on top and both sides of the body, with an oral cavity at the base of the nasal cavity, a neck permanently attached to the base, and a nasal cavity at one end of the neck. The auxiliary disassembly and installation structure is constructed using grooves on both sides of the torso and inside the top end. Insert blocks are used to secure the top and side of the insert block to the arm and neck base.
In the ideal situation, a duct opening should be located on one end of the animal's trunk and arm. Arms serve as a framework for constructing and dismantling the trunk, reserved groove, and insert block. The width of the reserved groove should be larger than the width of the insert block. The balls should be of the same size and spaced apart. A protective layer of glass fiber fabric is applied to the body. Common waste liquid collection components include slots, connecting bars, hinge seats, and collection boxes. The base of the trunk is split in half, creating two pieces: a connecting bar with two bottoms, a hinge-joined collecting box with two ends, and a hinge-seat attached to the bottom of the connecting bar. One end of a connecting bar is physically linked to a larger slot on the inside, while the other end is connected to a fixing block.

The present invention offers several benefits over the prior state of the art, such as a faster learning curve, reduced joint friction, and easier assembly and storage processes. It also includes a system for collecting waste liquid, which includes a slot, connecting strip, hinge seat, and collecting box. This system allows for easy removal and disposal of waste liquid when a catheter is used to inject a solid or liquid into the oesophagus.

The innovation model consists of the trunk, upper limbs, and a neck connecting the head to the trunk. The torso is formed by the combination of the abdominal cavity and chest cavity, each with a stomach sac and lung sac. The oesophagus facilitates communication between the nasal cavity and the stomach pouch. Central venous catheters (CVCs) are located in the center of the clavicle bone on both sides of the trunk, and PICC catheters are likely to be inserted into the middle of each upper limb.

The neck is a cylindrical structure with an open end that connects the head to the base of the skull and the trunk to the upper center of the skull. The front and rear of the two sides of the head are joined by a series of hinges on the same side of the skull. The gastric pouch has both an opening and closure, and the nasal airways are created via a triangular tube shaped like "Y."

The connection between the base of the oesophagus and the entrance of the gastric pouch is at the intersection of the two structures. A cap can be used to disguise the exit of the stomach pouch.

In conclusion, the invention offers numerous advantages over the prior state of the art, including a faster learning curve, reduced joint friction, and easier assembly and storage processes.

The text describes the process of installing a central venous catheter (CVC) catheter under each clavicle, including a hole for inserting the CVC into the trunk cavity, a cover plate, and a hinge. The components should be arranged in a central place on the trunk.

To implant a PICC catheter, an incision is made in the middle of the upper limbs, followed by the placement of the installation hole, a cover plate, and a hinged PICC duct cover. The PICC clip, mounting post, or hook secures one end of the PICC catheter to the device, while the other end extends beyond the chest.

The animal's mouth has a funnel-like shape, with the trachea joining to one end of the mouth and the broad end exposed to the outside of the skull. The trachea can interact with the lung sac through an opening. To achieve precision, a duplicate of the inside of the mouth is placed within the mouth itself.

A dental cavity model is used to represent the mouth cavity, with both upper and lower tooth types joined by a shaft. A spinning shaft is inserted into two holes in the mouth cavity to provide the desired effect.

A cardiopulmonary resuscitation (CPR) simulation board is placed in a hole cut into the front of the body during installation. The chest cavity is equipped with springs attached to the back wall and the simulation board. A vest made of elastic wraps around the torso is used to create the entire human body.

The utility model offers a significant advantage over previous studies, as it simplifies the teaching and practice of normal nursing procedures related to esophageal surgery.

The torso 3 is a shell structure with a connected chest cavity and an abdominal cavity, a lung sac 5 is provided in the chest cavity, a gastric sac 7 is provided in the abdominal cavity, and a nose 11 is provided on the front of the head 12, Eyes and mouth 10; two nostrils are provided on the nose 11, an oral cavity model is provided inside the mouth 4, the neck is a cylindrical structure with open ends, and its upper end is connected to the head 1. The lower end is communicated with the upper middle of the torso 3. The nose 11 is connected to the gastric pouch 7 through the esophagus 113, and the mouth 10 is connected to the lung pouch 3 through the trachea 6.

This article provides a comprehensive overview of the technological solutions included in various iterations of the current utility model, including images and implementations. The model includes an anterior and posterior section, with hinges on one side connecting the front and rear components. The airway linking the throat to the nasal passages and trachea is easily navigated when the front half of the throat is opened. The oesophagus, trachea, and mouth are pathways that allow air to come into contact with the lungs and stomach once it has passed through the neck.

A central venous catheter (CVC) is positioned on either side of the trunk, and a percutaneous internal catheter (PIC) is positioned in the middle of the two upper limbs. The gastric pouch, made of rubber or similar elastic material, creates an opening and an outflow. A nasal cavity tube facilitates the connection between the two nostrils. Joint connections, threaded connections, or direct fusion of pipes can be used to link two tubes to the nostrils.

To implant a CVC into the body, a hole must be drilled below the collarbone on both sides, covered with a plate, and secured to the cover plate using a hinge. The cover plate can be opened and closed, and a draw ring is accessible from the outside of the device. The CVC catheter installation hole makes it easy to enter and remove the catheter from the patient's body.

A CVC clip may be located in the trunk cavity, directly beyond the hole used to implant a CVC catheter. The CVC catheter is then inserted into the trunk cavity using the CVC catheter hole, opening the lid, and sealing the end with a CVC clamp. The other end is left exposed outside the trunk during the installation process.

An alternate strategy involves inserting a mounting post into the lumen of the trunk behind the CVC catheter mounting hole, securing the lower end to the inner wall of the trunk, and finally putting the CVC catheter into the lumen by opening it at one end. A ring buckle or the CVC itself can be attached to one end of the catheter.

The third example demonstrates the process of implanting a percutaneous intravenous central catheter (PIC) through an access hole in the center of each upper limb. A cover plate is attached to the installation hole for the PICC catheter, which is done by drilling. The cover plate is hinged and can be opened and closed at your discretion. The PICC catheter hole allows easy insertion and removal of the catheter.

During the procedure, one end of the catheter is inserted into the lumen of the upper limb via the PICC catheter hole. The cover is then opened, and the other end of the catheter is secured with the PICC catheter clip into place. The clip is inserted into the upper limb cavity, slightly beyond the operational hole of the PICC catheter. The other end of the PICC catheter is often exposed to the area of the upper leg that is exposed to the environment.

A mounting post is attached to the inner wall of the upper limb, immediately below the aperture for inserting the PICC catheter. The tip of the PICC catheter is inserted into the upper limb lumen by opening the hole in the catheter. There is also the possibility of securing the PICC catheter with a ring buckle and then inserting a hook into the lumen of the upper limb, slightly beyond the hole used for the installation.

The fourth embodiment shows the process of introducing a model of the interior of the mouth into the mouth and connecting it to the inside of the mouth by using mounting holes on either side of the cavity. The dental model consists of an upper and lower model of the teeth, as well as an image of the rear of the top and lower models. A rotating shaft is used to help nursing staff quickly understand how to care for different sections of the oral cavity.

The sixth version includes a cardiopulmonary resuscitation (CPR) simulation board 8 attached to the front of the body. The chest cavity and the base of the spring are connected in some way for the purpose of providing support. A link is used to connect the top end of the CPR simulation board to the interior of the board, and a permanent connection is used to secure the back wall in its current position.

In conclusion, the use of various methods and devices for implanting and removing PICC catheters has evolved over time.

The sixth embodiment of the esophageal surgical nursing operations education model demonstrates a strategy to improve training results and make cardiopulmonary resuscitation (CPR) practice more realistic. This approach involves placing an elastic vest around the exterior of the body, with an instructive model for esophageal surgical nursing operations for the torso and arms. The torso features a resistant layer at either end and a waste fluid collection layer at the base of the human body.

The auxiliary disassembly and installation structure consists of reserved grooves inside the sides and top of the trunk, insert blocks in spaces between balls, and mounting grooves on both the top and bottom of the interior of the component. The insert block is placed on the arm, and a secure placement can be achieved by velcroing the bottom of the collar.

Before installing or removing the insert block, it is necessary to determine the inner diameter of the reserved groove and ensure it is larger than the block's outer circular diameter. The block then fits into the groove and is secured to both the trunk and the reserved groove. The balls are uniformly placed over the top and bottom of the groove, and the arm can be removed by using the insert block.

In the second edition of the configuration, the inside of the trunk is equipped with a stomach. Glass fibre fabric is used to construct the wear-resistant layer, which is then attached onto the body via adhesive connections. The protective covering forms the outside of the trunk and arm, protecting the model from the environment and prolonging its lifespan.

A frame for collecting waste liquids is comprised of a slot, a connecting bar, a hinge seat, and a collecting box. A connecting strip is fixed to a fixing block at one end, and the liquid is directed into a collecting box. The process for giving a solid or liquid by a catheter into the oesophagus is shown in the pictures.

The utility model describes the process of applying the model, where balls fall uniformly into the selected slot, and the arm can be removed by inserting the block into the designated groove. The protective coating is applied using glue and connections, using the fiberglass fabric that makes up the layer.
