Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a peritoneal dialysis positioning system for nephrology. Background Art

[0002] Peritoneal dialysis uses 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 (also known as a dialysis tube) by gravity. Due to the concentration gradient difference of solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); water moves from the hypotonic side to the hypertonic side (osmotic effect). 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 imbalance. The essential equipment for peritoneal dialysis includes peritoneal dialysis tubes, peritoneal dialysis fluid and other auxiliary equipment. The basic conditions for selecting peritoneal dialysis tubes are: they can be left in the abdominal cavity for a long time; the dialysate has smooth inflow and outflow to ensure a good dialysis effect; they are non-irritating to the body and have no adverse tissue reactions; they are not prone to displacement, slippage, blockage, omental wrapping, cellulose block formation and infection.

[0003] A peritoneal dialysis positioner for the Department of Nephrology in the prior art is provided with a slide and a through hole through the interior of the main body, the slide is located on one side of the through hole, the inner wall of the through hole is interactively connected with a connecting plate 1, one end of the connecting plate 1 is fixedly connected with a clamping plate, the lower surface of the connecting plate 1 is fixedly connected with a spring 1, one end of the spring 1 is fixedly connected to the inner wall of the through hole, a pressing rod is provided inside the slide, the lower end of the pressing rod is fixedly connected with the connecting plate, and one end of the connecting plate is fixedly connected with a ring. The utility model device can buckle the dialysis tube when someone accidentally touches the dialysis tube through the mutual cooperation of the connecting plate 1 clamping plate and the spring 1 inside the through hole, so as to prevent the dialysis tube from contacting the patient and affecting the patient's wound, thereby causing great pain to the patient. Through the cooperation of the pressing rod and the ring, the dialysis tube can be easily taken out after the patient's dialysis is finished, so it is convenient and quick.

[0004] However, when the device is used, it can only fit one size of dialysis tube, which is quite limited and cannot be adjusted better according to different dialysis tubes.

[0022] The bottom plate 2 is arranged on the back side of the connecting belt 1 .

[0023] Limiting grooves 24 are provided on both sides of the limiting member 21 , and limiting plates 35 are fixedly installed on the tops of both sides of the inner side surface of the moving circle 34 , and the limiting plates 35 are slidably connected to the inner side surface of the limiting grooves 24 .

[0024] A threaded ring 13 is fixedly mounted on the front of the connecting belt 1 . The threaded ring 13 is arranged on the outer side of the through-hole 11 . An outer cover 14 is threadedly connected to the outer side of the threaded ring 13 . The outer cover 14 is sleeved on the outer side of the limiting member 21 .

[0025] An air pipe is fixedly installed inside the bottom ring 3 on one side close to the limiting member 21 , and the other end of the air pipe penetrates into the interior of the airbag 22 .

[0026] The outer diameters of the threaded sleeve 36 and the bottom ring 3 are both smaller than the inner diameter of the through hole 11 .

[0027] The diameters of the through openings 11 opened by the connecting belt 1 and the sensitive adhesive layer 12 are different. When in use, the limiter 21 is arranged on the inner side of the through opening 11 opened by the connecting belt 1, and the bottom plate 2 is arranged on the inner side of the through opening 11 opened by the sensitive adhesive layer 12, so as to prevent the sensitive adhesive layer 12 from adhering to the top of the bottom plate 2, and to prevent the bottom plate 2 from being pulled when the connecting belt 1 and the sensitive adhesive layer 12 need to be replaced later; By sliding the limiting plate 35 on the inner side of the limiting groove 24 , the moving ring 34 can be limited during use to prevent the moving ring 34 from rotating.

[0028] The working principle of the peritoneal dialysis positioning system for nephrology provided by the present invention is as follows: When in use, first pass one end of the dialysis tube through the inner side of the rubber sleeve 23, then the user brings the bottom plate 2 into contact with the patient's skin, and then sleeve the connecting belt 1 and the sensitive adhesive layer 12 on the outer side of the limiting member 21 through the through hole 11, and make the sensitive adhesive layer 12 adhere to the patient's skin, so as to limit and fix the limiting member 21 and the bottom plate 2, and then the user rotates the threaded sleeve 36 to make the threaded sleeve 36 be threadedly connected to the outer side of the limiting member 21, and move toward the side close to the connecting belt 1. When the threaded sleeve 36 moves toward one end of the connecting belt 1, it will drive the moving circle 34 to move, so that the moving circle One end of 34 pushes the movable plate 33 and the piston sleeve 32, so that the movable plate 33 and the piston sleeve 32 slide on the inner side of the sliding cavity 31, thereby squeezing the gas on the inner side of the sliding cavity 31, so that the gas on the inner side of the sliding cavity 31 enters the inner side of the airbag 22 through the pipeline, so that the airbag 22 is inflated and bulged, and the rubber sleeve 23 moves to one side of the dialysis tube, so that the rubber sleeve 23 is wrapped around the outer side of the dialysis tube, thereby limiting and fixing the dialysis tube. When drainage is not needed, the user can thread the outer cover 14 on the outer side of the threaded ring 13, so that the dialysis tube and the limiting member 21 are covered on the outer side of the outer cover 14.

[0034] The rubber pad 43 can increase the friction with the patient's skin when in use, and the ventilation holes 44 and the sponge pad 42 can absorb the sweat produced when the patient's skin sweats.

[0035] The working principle of the peritoneal dialysis positioning system for nephrology provided by the present invention is as follows: When in use, the user first places the base plate 2 on the patient's skin, and then puts the connecting belt 1 and the sensitive adhesive layer 12 on the outer side of the limiting member 21 through the through-hole 11, and then magnetically attracts the first flexible magnetic plate 4 and the second flexible magnetic plate 41 to limit the base plate 2, and then adheres the sensitive adhesive layer 12 to the patient's skin, thereby limiting the limiting member 21 and the base plate 2.

[0036] Compared with the related art, the peritoneal dialysis positioning system for nephrology provided by the present invention has the following beneficial effects: By magnetically attracting the first flexible magnetic plate 4 and the second flexible magnetic plate 41 , the bottom plate 2 and the connecting belt 1 can be limited during use, thereby increasing the stability of the bottom plate 2 after installation.
