Disinfection cleaning rod for filter type citric acid hemodialysis machine

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a disinfection cleaning rod for a filter type citric acid hemodialysis machine. The disinfection cleaning rod comprises a cleaning rod pipe and a sealing cover, wherein a filter assembly is arranged in the sealing cover in a matched mode, the filter assembly comprises an upper fixing ring and a lower fixing ring, inserting plates which are distributed at equal intervals are welded to the periphery of the outer wall of the bottom of the upper fixing ring, protruding blocks are welded to the bottom ends of the outer side walls of the inserting plates, inserting plate grooves which are distributed at equal intervals in an annular structure are formed in the periphery of the outer wall of the top of the lower fixing ring, and positioning grooves communicating with the inserting plate grooves are formed in the periphery, close to the outer side walls of the inserting plate grooves, of the lower fixing ring. The disinfection cleaning rod has the beneficial effects that an existing ultrasonic welding structure is replaced by a clamping sealing and threaded connection structure, a sealing ring made of silica gel is arranged between the sealing cover and the cleaning rod pipe, the air tightness does not need to be checked after assembly and processing are completed, equipment and labor investment is saved, and the problem that the service life is influenced due to water leakage and air leakage after the disinfection cleaning rod is put into use is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disinfection cleaning stick for a filter type citric acid hemodialysis machine. Background technique [0002] With the continuous improvement of people's living standards, people's lifestyles and eating habits are becoming more and more irregular, leading to more and more patients with renal failure, drug poisoning, uremia and other diseases; Hemodialysis machine is mainly used for treatment. Hemodialysis machine is to pass the blood in the human artery through the blood pipeline, input it into the hemodialysis machine for filtration, filter out harmful substances in the blood, and then input it into the human body through the dialysate pipeline. , so as to achieve the effect of treating diseases; after the traditional hemodialysis machine is used, it needs to be cleaned, that is, the disinfectant sodium hypochlorite is put into the cleaning container, and the cleaning ...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a sterilized cleaning rod for filter-type citric acid hemodialysis machine, to solve the above-mentioned background technology that the cleaning rod tube adopts plastic extruded pipe material, and the sealing cover is not firmly ultrasonically welded, and the sealing performance is poor, resulting in defective products in the production process. Increase, more complaints from after-sales customers; after ultrasonic welding of the cleaning rod tube and sealing cover, the watertightness and airtightness need to be inspected manually and by equipment, and it is not easy to detect defective seals. After the product is put on the market, there are many after-sales complaints.
