Problems solved by technology

Its disadvantages are: 1. One end of the whole peritoneal dialysis pipeline is connected to the patient's abdominal cavity, and the other end is the waste liquid outlet. Waste fluid backflow into the patient's abdominal cavity occurs, but in some cases, there is still the possibility of pipeline contamination when the machine fails, and the patient still has the risk of infection; 2. After the daily APD treatment, about 12 -15L of liquid, and cleaning and disinfection, reserved for use the next day, will add more operational difficulties and physical burden to the patient
[0006] But about a kind of automatic peritoneal dialysis machine waste liquid collecting device of the present invention, there is no report yet

Embodiment 1

[0043] Please refer to the attached figure 1 , with figure 1 It is a structural schematic diagram of a waste liquid collection device of an automatic peritoneal dialysis machine in this embodiment. The automatic peritoneal dialysis machine waste liquid collection device includes a purification device (1), a temperature control system (2), a single valve (3), a waste liquid collection device (4), and a catheter (5);

[0044] Please refer to the attached figure 2 , attached image 3 , attached Figure 4 , with figure 2 , 3 It is a schematic diagram of the combination of a waste liquid collection device of an automatic peritoneal dialysis machine and the abdominal cavity in this embodiment, and the attached Figure 4 It is a plan view of the combination of an automatic peritoneal dialysis machine waste fluid collection device and the abdominal cavity in this embodiment. The purification device (1) is cylindrical, and the upper end of the purification device (1) is sealed...

Embodiment 2

[0052] Please refer to the attached Figure 5 , with Figure 5 It is a schematic diagram of the use of an automatic peritoneal dialysis machine waste liquid collection device in this embodiment.

[0053] The use process and method of the automatic peritoneal dialysis machine waste liquid collection device:

[0054] At first the catheter connector (51) on the upper end catheter (5) of the purification device (1) is connected with the automatic peritoneal dialysis machine (7); The calibers of the liquid bag (6) pipeline port and the waste liquid pipe port match, and can be tightly connected conveniently. Therefore, we use the 5L fasting liquid permeation bag (6) that has completely emptied the peritoneal dialysis fluid in the automatic peritoneal dialysis treatment to design a waste liquid collection device for an automatic peritoneal dialysis machine, which is the waste liquid collection device (4).

[0055] Patients need to undergo peritoneal dialysis treatment once a day, ...

Abstract

The invention discloses a waste liquid collecting device of an automatic peritoneal dialysis machine. The automatic peritoneal dialysis machine comprises a purification device, a temperature control system, one-way valves, the waste liquid collecting device and catheters; the catheter is hermetically connected to the lower end of the purification device; the temperature control system is connectedto the lower end of the catheter; the catheter is connected to the lower end of the temperature control system; the one-way valve is hermetically connected to the lower end of the catheter; the catheter is connected to the lower end of the one-way valve; the lower end of the catheter is divided into two catheters in a herringbone shape; an abdominal cavity connector is arranged at the tail part of one catheter; the one-way valve is connected to the tail part of the other catheter; the catheter is connected to the lower end of the one-way valve; a catheter adapter is arranged at the lower endof the catheter; the waste liquid collecting device is hermetically connected to the catheter adapter; and a catheter connector is arranged at the upper end of the waste liquid collecting device. Thewaste liquid collecting device has the advantages that a whole peritoneal dialysis tube is sealed in treatment, and a waste liquid bag is emptied after treatment and is directly cut and discarded, sothat the possibility that the dialysis tube is polluted can be effectively reduced, and the risk of abdominal infection of a patient is lowered.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an automatic peritoneal dialysis waste liquid collection device. Background technique [0002] With the increasing incidence of chronic kidney disease and other chronic diseases (such as diabetes and hypertension) that easily lead to kidney damage worldwide, the number of patients with ESRD continues to increase, and such patients can only be maintained by renal replacement therapy. Peritoneal dialysis is one of the main renal replacement therapies for ESRD, and the annual increase rate of patients receiving peritoneal dialysis in my country is about 20%. APD is a new peritoneal dialysis mode, which uses a peritoneal dialysis machine for peritoneal dialysis treatment. APD can be performed during sleep at night to improve the quality of life of patients during the day; it is more conducive to the removal of small molecular solutes and improve the adequacy of dialysis; ...
