Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a special abdominal belt for peritoneal dialysis. Background Art

[0002] A peritoneal dialysis belt is a special belt used by patients with chronic kidney disease to fix their peritoneal dialysis catheters. Currently, peritoneal dialysis belts in the prior art are generally attached with Velcro, but the Velcro easily loses its stickiness after being opened repeatedly, which not only poses a risk of the peritoneal dialysis belt falling off, but also easily causes the patient's peritoneal dialysis catheter to fall off, increasing the risk of infection for the patient.

[0003] Therefore, a special abdominal belt for peritoneal dialysis is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a peritoneal dialysis belt in order to solve the above-mentioned problem, which improves the problem that the Velcro easily fails in adhesion after repeated opening, which not only causes the risk of the peritoneal dialysis belt falling off, but also easily causes the patient's peritoneal dialysis catheter to fall off, increasing the risk of infection for the patient.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a special abdominal belt for peritoneal dialysis, comprising: a waist and abdomen, a placement box is installed on the front surface of the waist and abdomen, and fixing belts are fixedly installed on both sides of the waist and abdomen; a fixing mechanism, the fixing mechanism is installed at one end of two fixing belts and can be used for patients with different waist circumferences; wherein the fixing mechanism includes a strip groove opened on the surface of one fixing belt, a soft rack is fixedly installed at the bottom of the inner cavity of the strip groove, and a fixing piece is fixedly installed at one end of the other fixing belt, and the fixing piece is used to fix and limit the strip groove.

[0006] Preferably, the fixing member includes a shell fixedly installed on one end of the fixing belt, the inner cavity of the shell is provided with a gear, a turntable is installed through one side of the shell, the turntable is located at one end of the inner cavity of the shell and is fixedly connected to the gear, the other fixing belt penetrates the shell and extends to the outside of the shell, and the gear is meshingly connected to the soft rack.

[0007] Preferably, a rotating wheel is sleeved on the surface of the turntable located outside the shell, and a plurality of limiting holes are opened on the surface of the rotating wheel. A fixing plate is fixedly installed on the top of one side of the shell, and an insertion rod is installed through the top of the fixing plate. The bottom end of the insertion rod passes through the limiting hole and is plugged into the limiting hole, and a handle is fixedly installed on the top of the insertion rod, and a reset spring is fixedly installed between the handle and the fixing plate.

[0008] Preferably, a guide push plate is provided on one side of the inner cavity of the shell, and clamping springs are fixedly installed around one side of the guide push plate, and one end of the four clamping springs away from the guide push plate is fixedly connected to the inner wall of the shell.

[0009] Preferably, a through groove is opened on one side of the top of the waist and abdomen, and a peritoneal dialysis catheter is installed in the inner cavity of the placement box. One end of the peritoneal dialysis catheter passes through the placement box and the through groove in sequence and extends to the rear side of the through groove.

[0010] Preferably, a limiting belt is fixedly installed on the front surface of the waist and abdomen and located on one side of the through-slot, and a Velcro is fixedly installed on the front surface of the waist and abdomen and located on the other side of the through-slot, and the limiting belt and the Velcro are bonded.

[0011] Preferably, a bearing seat is installed at the penetration point between the turntable and the shell, the inner surface of the bearing seat is rotatably connected to the turntable, and the outer surface of the bearing seat is fixedly connected to the shell.

[0012] The beneficial effects of the utility model are:

[0013] 1. When used by patients with different waist circumferences, the patient inserts one end of a fixing belt into the shell to make the soft rack and the gear tightly contact each other. At the same time, the patient rotates the gear through the turntable, and the gear drives the fixing belt to extend to the other side of the shell through the meshing connection with the soft rack. When the two fixing belts are adjusted to a suitable waist circumference, the patient inserts the insertion rod into the limiting hole on the surface of the turntable, which changes the traditional Velcro pasting and fixing method, avoiding the risk of Velcro failing to stick after a period of use, resulting in the risk of the fixing belt falling off the waist and abdomen;

[0014] 2. When the patient inserts a fixing belt into the inner cavity of the shell, the fixing belt is guided by the extrusion of the guide push plate so that the bar groove is stuck on the surface of the gear, and as the patient continues to move forward, the soft rack and the gear can be fully pressed against each other. In addition, through the setting of the limiting belt and the Velcro, the peritoneal dialysis catheter can be fixed after being inserted into the patient's body, avoiding the peritoneal dialysis catheter from sliding during dialysis and causing the peritoneal dialysis catheter to fall off.
