Description

Technical Field

[0001] The utility model belongs to the field of medical waste liquid collection devices, in particular to an automated peritoneal dialysis machine waste liquid collection device. Background Art

[0002] Peritoneal dialysis is a dialysis method that uses the body's own peritoneum as a dialysis membrane. The dialysate infused into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum, removes the metabolic products and excess water retained in the body, and replenishes the body's necessary substances through the dialysate. By constantly updating the peritoneal dialysis fluid, the purpose of kidney replacement or supportive treatment is achieved. Peritoneal dialysis is suitable for acute and chronic renal failure, high volume load, electrolyte or acid-base imbalance, drug and food poisoning and other diseases. The function of the peritoneal dialysis machine is to infuse the dialysis fluid into the patient's peritoneal cavity, use the peritoneum for dialysis, and then drain the exchanged dialysis waste fluid out of the peritoneal cavity; the fully automatic peritoneal dialysis machine can connect the peritoneal dialysis tube to the fully automatic peritoneal dialysis machine before the patient goes to bed, and then set the program. The fully automatic peritoneal dialysis machine will monitor and record each infusion volume, abdominal retention time, drainage time, drainage volume and control the temperature of the peritoneal dialysis fluid, etc., automatically perform dialysis treatment for the patient without affecting the patient's normal life.

[0003] At present, automated peritoneal dialysis machines are generally equipped with a collection bucket to collect waste liquid. The amount of peritoneal dialysis waste liquid generated by patients after a night of peritoneal dialysis will be very large. Therefore, the waste liquid in the bucket needs to be processed before reusing the collection bucket. However, the collection bucket filled with waste liquid is too heavy, and if the transfer process is too bumpy, it will cause the waste liquid to spill from the connecting tube or other openings used to connect the peritoneal dialysis tube. After the waste liquid in the collection bucket is discharged, the collection bucket needs to be cleaned and disinfected. However, the existing collection bucket is manually cleaned and disinfected by medical staff, which requires medical staff to come into close contact with the waste liquid remaining in the bucket. If the patient himself has an infectious disease, it is easy to cause the spread of the disease. Utility Model Content

Fixing plates 11 are horizontally fixed on the left and right side walls of the top cover 4. Each fixing plate 11 is provided with a through hole for screws to pass through. Mounting plates 12 are horizontally fixed on the left and right side walls of the cavity 1. Each mounting plate 12 is provided with a threaded hole threadedly matched with a corresponding screw, thereby fixing the top cover 4 to the cavity 1. Of course, a quick-release rod can also be used between the cavity 1 and the top cover 4. The quick-release rod is a common fastening part, which is mainly used to fix the front and seat post of a bicycle.

[0026] The top cover 4 is made of a hard material such as PC, PMMA, PS, PE and PVC. The transparent top cover 4 is more convenient for viewing the situation inside the cavity 1.

The sealing cover can effectively prevent the waste liquid inside the cavity 1 from leaking from the water inlet 9.

[0030] The cavity 1 is provided with a drainage member for discharging waste liquid in the cavity. A drainage pipe 14 communicating with the interior of the cavity 1 is fixed on the right side wall of the cavity 1. A drainage valve 15 for controlling the water flow and switching is connected to the drainage pipe 14. The drainage valve 15 is used to adjust the size of the waste liquid discharged from the cavity 1 by the drainage pipe 14, which can effectively avoid the waste liquid splashing due to the rapid water flow. Of course, the drainage member can also adopt a drainage hole and a plugging valve. The drainage hole and the plugging valve are in an interference fit.

When in use, the water source of the external water pipe is opened, so that the water source is sprayed out from the high-pressure nozzle in a mist form, thereby using the water mist to impact the residual waste liquid or impurities on the inner wall of the cavity 1, so that the waste liquid or impurities flow to the bottom of the cavity 1 and are discharged along with the water flow.

The ultraviolet rays irradiated by all the ultraviolet lamps 13 are used to sterilize the interior of the cavity 1 to avoid the presence of bacteria and viruses remaining in the cavity 1; this section of the scheme as a whole constitutes a disinfection component for disinfecting the interior of the cavity 1; of course, the disinfection component can also use infrared sterilization lamps, and a plurality of infrared sterilization lamps are fixed on the inner bottom of the top cover 4 to kill viruses and bacteria by infrared irradiation. It should be noted that when using infrared sterilization lamps, the cavity 1 and the top cover 4 need to be made of high temperature resistant materials, and the infrared sterilization lamps will generate a higher temperature during irradiation.

[0034] In actual use, when collecting waste liquid, the waste liquid collection device is moved to the side of the automated peritoneal dialysis machine, the peritoneal dialysis tube on the automated peritoneal dialysis machine is connected to the connecting tube 6, and the waste liquid drawn out of the automated peritoneal dialysis machine is introduced into the cavity 1 through the connecting tube 6; when the patient's peritoneal dialysis treatment is completed, the connection between the peritoneal dialysis tube and the connecting tube 6 is removed, and the connecting tube 6 is bent to make the inner wall of the bending part of the connecting tube 6 fit together, thereby sealing the connecting tube 6, and then the bent end of the connecting tube 6 is clamped in the buckle; the medical staff needs to check the inside of the cavity 1 When the waste liquid is to be processed, the telescopic rod 2 is first stretched to a suitable length according to one's own needs, and then the handle 3 is held by hand, and the cavity 1 is dragged by the handle 3 and the telescopic rod 2, so that the cavity 1 moves under the action of the universal wheel 17, thereby shifting the position of the waste liquid collection device.
