This Patent Falls In The Field Of Surgical Equipment In Medical Applications To Indwell The Catheter Clamp In Order To Drain The Urinary Bladder.
Abstract: Foley Catheter is one of the most common medical equipment used in day-to-day medical and surgical care. A normal Foley’s urethral catheter lacks an instrumentation for clamping which is required and plays a major role in retraining of urinary bladder musculature before the catheter is taken off. This is usually used to drain the urinary bladder during selective surgeries, long term bed ridden patients and stroke patients. It is required to indwelling urinary catheters be clamped intermittently to fill the bladder and restore bladder function before removal. The clamping process is essential to strengthen the bladder detrusor muscle, improve muscle tone and sensation of the bladder and stimulate normal filling and emptying of the bladder. Hence an inbuilt sterile equipment designed for clamping of Foley’s catheter would be of immense benefit to the medical and surgical practice. The clamp has to be applied on to Foley’s catheter after the catheter is inserted inside patient. We propose a modification to Foley’s catheter helping in achieving this function since the catheters are clamped for 4 hours and then unclamped for 15 minutes allowing the bladder to drain completely. In this invention we intend to design a tubular clamp or sheath, divided longitudinally to facilitate radial placement with a planar bottom surface having a rounded proximal side. The distal end of the clamp will include a locking lip that extends from the upper inside surface of the distal end. The top surface has a clamping surface which will extend in a perpendicular direction from the top surface. When this surface is pressed down, the top surface engages beneath the locking lip of the distal end of the catheter clamp. The clamp will include a grip for retaining the catheter against movement along its length and a region between the opening and the grip in which the catheter can be formed into a loose loop such that the catheter can move freely to a limited extent through the opening when retained at the grip.

Specification
Description:The tube has two separated channels or lumens running down its length. One lumen (101), open
at both ends, drains urine into a collection bag. This wire or flexible member is fixed to the
inside proximal tip and when pulled causes the catheter's closed end to foreshorten, thereby
radially displacing the outwardly projecting portions to an open configuration. The reversibly inflatable balloon 103 is given a substantially spherical form causes the
equatorial part of the balloon sphere to push in a radial direction the flexible tube slit portions
thereby displacing the tube slit portions. The bladder opening (104) is shown provide a hollow elastomeric tube, and a method of
aspirating the bladder after surgery and in certain medical conditions. The balloon (105) is inflated with sterile water when it lies inside the bladder to stop it from
slipping out. Manufacturers usually produce Foley catheters using silicone or coated natural.
Coatings include polytetrafluoroethylene, hydrogel, or a silicon elastomer – the different
properties of these surface coatings determine whether the catheter is suitable for 28-day or
3-month indwelling duration. 106 represents the inbuilt clamp design whose diameter is adjusted between 0.5 to 0.75 Fr which
is greater than the Foley’s Catheter with 1Fr representing 0.33mm. The length is adjusted to
atleast 3cm with a material that should be able to withstand the deformation. This axis of bend
to be made to clamp the Foley’s. The front view of the Foley’s structure where 201 shows the outward projection hinge to hook
on distant part of the clamp. 202 is the part of the catheter which slides the clamp outward to fit on to the Foley’s catheter. The corresponding part forming lock key mechanism is shown in 203. Clamping is done as shown in 301 after bending the clamp with Foley and attaching the lock
and key part to hold the clamp in the key position. The back view of the Foley’s Catheter is shown where the linear mark (401) is able to withstand
the bend in the clamp. , Claims:A built in clamping equipment is designed before taking off the catheter which avoids trauma,
bleeding and infections. The clamp is included with a grip for retaining the catheter against movement along its length
and a region between the openings. The grip is formed into a loose loop such that the catheter can move freely to a limited extent
through the opening when retained at the grip.
