Problems solved by technology

This is almost unacceptable in the medical field as it presents a significant medical risk
In addition, there are now pre-prepared dialysate in the factory, which is packed in a medical packaging bag. Although this dialysate is convenient to use, it is expensive, has a short shelf life, and may be contaminated by bacteria after a long storage time. At the same time, the cost is high, and many patients cannot accept it

Embodiment Construction

[0055] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0056] Such as Figures 1 to 5 As shown, a concentrated liquid supply system for hemodialysis concentrate is mainly composed of a liquid dispensing machine P, a liquid storage tank 14, a joint J, a disinfection cover G and some connecting piping systems. Among them, the basic structure of the liquid dispensing machine P adopts the Chinese invention patent previously applied by the applicant, and its patent number is 201010524202.8. The liquid dispensing machine P used in this case has been further improved on the previous patented technology.

[0057] refer to figure 1 , 2 , the above liquid dispensing machine P is mainly composed of a liquid dispensing barrel 1, a sealing cover 2, a first valve 4, a water pipe 5, a first water pump 6, a three-way outlet pipe 7, a water return pipe 8, a finished product liquid output pipe 9, and a disinfectant discharge pip...

Abstract

The invention discloses a centralized hemodialysis concentrated liquid feeding system comprising a liquid preparing machine which feeds liquid to a liquid storage tank, the liquid storage tank is connected with a second delivery pipe through a first delivery pipe and a filter, a group of joints are connected on the second delivery pipe, and a disinfection cap is arranged on each joint; after being connected with an air inlet pipe, the outlet end of the second delivery pipe is provided with a seventh valve and finally communicated with the liquid storage tank, and the air inlet pipe is connected with an air compressor. The liquid feeding system is totally enclosed in the entire operation process, pollution due to the external environment is prevented effectively, blind-point-free disinfection can also be performed, no residue is left after disinfection, the concentrated liquid which is sterile, ultrapure and normal in concentration can be prepared on use fields, and the safe concentrated liquid can be delivered to a dialysis machine through the liquid feeding system.

Description

technical field [0001] The invention belongs to the field of hemodialysis, and in particular relates to a centralized liquid supply system for concentrated hemodialysis fluid. Background technique [0002] As we all know, the hemodialysis machine has components such as a liquid dosing pump and a conductivity detector. When it works, it needs to inhale hemodialysis concentrate (that is, a high-concentration liquid rich in K and NA plasma), and at the same time inhale a corresponding amount of pure water in order to prepare The dialysate with the same concentration of K and NA ions as the human body is used for hemodialysis. [0003] In the past, the dialysis powder rich in K and NA was generally added to an open liquid mixing tank at the use site, and then the corresponding amount of pure water was added, and the hemodialysis powder of the required concentration was prepared by purely manual stirring. Concentrate. Since the upper part of the liquid dispensing barrel is open...
