Problems solved by technology

[0007] Within a day, the patient undergoes several cycles of draining, filling and indwelling. The manual peritoneal dialysis performed by the patient requires a considerable amount of time and energy for the patient. Long-term peritoneal dialysis produces peritonitis, and the peritoneum thickens and becomes fibrotic, which is not conducive to Osmotic exchange of blood and dialysate, peritoneal dialysis requires high sanitation conditions, aging population, complex operation of patients, short dialysis cycle, inconvenient, replacement of dialysate bag during daily peritoneal dialysis will cause infection at the outlet and tunnel

Embodiment 1

[0038] Such as Figure 1-4 As shown, this embodiment provides a sealed peritoneal dialysis device, including a catheter 11 and a dialysate box 5, the dialysate box 5 is used to place the dialysate, and the catheter 11 communicates with the dialysate box 5 through the inlet tube 3 and the outlet tube 4 The dialysate box 5 connected to the inlet tube 3 holds the dialysate before dialysis, and the dialysate box 5 connected to the outlet tube 4 holds the dialysate after dialysate.

[0039] Such as figure 2 As shown, the conduit 11 of this embodiment is divided into two parts, specifically including a double-way pipe 11 and a single-way pipe 13. The double-way pipe 11 is that the middle part of the conduit 11 is provided with a partition, and the partition divides the conduit 11 into two parts. There are two upper and lower pipelines, the double-way tube 11 is arranged on the upper part of the abdominal cavity, and becomes the single-way tube 13 after passing through a U-shaped s...

Embodiment 2

[0045] Such as Figure 1-6 As shown, this embodiment provides a sealed peritoneal dialysis device. On the basis of Embodiment 1, the sealed peritoneal dialysis device of this embodiment also has the following characteristics:

[0046] Such as Figure 5-6 As shown, the dialysate box 5 of this embodiment can contain the dialysate and the dialysate after dialysate. Generally, a dialysis device needs to be provided with two dialysate boxes 5, but the two dialysate boxes 5 have exactly the same structure, and only hold Specifically, the dialysate box 5 includes a first box body 51 and a second box body 52, one side of the first box body 51 is provided with a bar-shaped protrusion 53, and a nozzle is provided on the bar-shaped protrusion 53 One side of the second box body 52 has a bar-shaped notch 54, and the bar-shaped notch 54 is provided with a socket 56. The first box body 51 is inserted into the bar of the second box body 52 through the bar-shaped protrusion 53. In the notch ...

Abstract

The invention discloses a sealed peritoneal dialysis device. The sealed peritoneal dialysis device comprises a catheter and a dialysate box. The catheter communicates with the dialysate box through anintroduction tube and a lead-out tube. The catheter comprises a double-way tube and a single-way tube, and the tail end of the double-way tube communicates with the single-way tube. A plurality of convex holes are formed in an U-shaped section of the tail end of the double-way tube, the tail end of the single-way tube is a suction section, and a plurality of through holes are formed in the suction section; and the dialysate box comprises a first box body and a second box body, the first box body is connected into a strip-shaped notch of the second box body through a strip-shaped protrusion inan inserted mode, and an inserting hole communicates with dialysate in the dialysate box. The convex holes for enabling the dialysate to flow out are formed in the upper part of the catheter, the exchange area of the dialysate in an abdominal cavity is larger, so that the time of peritoneal dialysis is shortened. A sealed dialysate box interface is hidden inside the box bodies to ensure that thedialysate is not in contact with a patient in the use process, the patient feels convenient and quick in the process of changing the liquid, the operation difficulty and intensity of the patient are reduced, and the probability of infection is reduced.

Description

technical field [0001] The invention relates to the field of dialysis medical equipment, in particular to a sealed peritoneal dialysis device. Background technique [0002] Kidney failure and poor kidney function are treated with dialysis, which removes waste, toxins, and excess water from the body. [0003] Hemodialysis and peritoneal dialysis are two commonly used dialysis methods to treat renal failure. [0004] Peritoneal dialysis utilizes dialysate infused into the patient's peritoneal cavity. The dialysate contacts the peritoneum in the patient's peritoneal cavity, and waste, toxins, and excess water enter the dialysate from the patient's bloodstream through the peritoneum. The transport of waste products, toxins and water from the bloodstream into the dialysate occurs by diffusion and osmosis. The spent dialysate is drained from the patient's peritoneal cavity to remove waste, toxins, and water from the patient's body, and then replaced. [0005] Fresh dialysate i...
