Description

Technical Field

[0001] The utility model relates to the technical field of peritoneal dialysis, in particular to a peritoneal dialysis positioning and fixing belt used in nephrology. Background Art

[0002] Peritoneal dialysis utilizes the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through a catheter via gravity. Due to the difference in solute concentration gradient on both sides of the peritoneum, the solute on the high-concentration side moves to the low-concentration side, and water moves from the hypotonic side to the hypertonic side. The peritoneal dialysis fluid is continuously replaced to achieve the purpose of removing metabolic products and toxic substances from the body and correcting water and electrolyte imbalances.

[0003] During the use of the peritoneal dialysis positioning fixation belt, the dialysis tube is simply adhered to the fixation belt with medical tape. Since the patient changes his body position or moves, the dialysis tube will shake and shift, and the dialysis tube will pull the skin wound, causing secondary damage to the wound, and even causing the dialysis tube to fall off and require reinsertion.

[0007] Preferably, the exhaust assembly includes an exhaust pipe for supplying air to the inflatable airbag, a gas storage box for storing gas is installed on one side of the positioning belt, a piston plate for squeezing gas into the exhaust pipe is slidably connected inside the gas storage box, a movable rod for driving the piston plate to move is slidably connected to the inner wall of the gas storage box, and a positioning assembly for preventing the movable rod from moving is installed on the positioning belt.

[0008] Preferably, the positioning assembly includes a push plate rotatably connected to one end of the movable rod, the push plate is provided with a slot, a block is inserted in the slot to prevent the push plate from rotating, and a baffle is installed on the positioning belt to prevent the push plate from moving.

[0009] Preferably, the number of the card blocks is set to multiple, and every two of the card blocks are set to a group. The two card blocks in the same group are connected by a support block, one side of the support block is fixedly connected with a spring for pushing the card block to move, and the outer wall of the support block is fixedly connected with a protrusion for facilitating medical staff to move the card block.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] In the present application, after the dialysis tube is inserted into the patient's body through the positioning belt, the medical staff can use the push plate to make the movable rod drive the piston plate to move, and the piston plate will squeeze the air in the air storage box and discharge it into the expansion air bag through the exhaust pipe. The expansion air bag is limited by the limit plate and can only expand inward to squeeze and fix the dialysis tube. Then the medical staff uses the protrusion to move the card block, and then rotates the push plate so that the card slot and the card block are on the same horizontal plane. Then release the protrusion, the spring will push the card block into the card slot so that the push plate cannot rotate. In this way, the push plate is blocked by the baffle and cannot move horizontally, and is limited by the card block and cannot rotate. The gas in the expansion air bag will not flow back into the air storage box, and the dialysis tube will be firmly fixed. BRIEF DESCRIPTION OF THE DRAWINGS
