Problems solved by technology

[0003] After the hemodialysis machine is used, the shell and the pipeline system need to be rinsed and disinfected regularly. However, when the hand-held sterilizer is used during the disinfection process of the hemodialysis machine shell, the hand-held sterilizer itself cannot be used due to the limited height of the staff. It does not have a height adjustment and rotation adjustment structure, so that the work progress of the disinfection of a higher-sized hemodialysis machine is not smooth, and it is easy to cause uneven spraying of the disinfectant

Embodiment 1

[0035] Basic as attached figure 1 to attach Figure 4 As shown, a hemodialysis machine disinfection device includes an inverted U-shaped frame 13, a guide shaft 15 is fixed with bolts on the frame 13, and a sterilizer is horizontally slid on the guide shaft 15. In this embodiment, the sterilizer includes The hollow body 14 has an opening on the left side of the body 14. The body 14 is rotatably connected with a tapered disinfection cover 141. The screw on the disinfection cover 141 is fixed with a support plate. The disinfection cover 141 is rotatably connected with the body 14 through the support plate. The disinfection cover 141 Made of elastic material, such as: rubber material. The first disinfection plate 145 is fixed with screws on the support plate of the disinfection cover 141, and the first disinfection hole 146 is provided on the first disinfection plate 145. The diameter of the first disinfection hole 146 is 0.1cm or 0.2cm, and the first disinfection plate 145 is a...

Embodiment 2

[0048] The difference between embodiment two and embodiment one is that, as attached Figure 5 As shown, a recovery tube 151 is glued and fixed on the disinfection cover 141, and one end of the recovery tube 151 communicates with the liquid inlet chamber.

[0049] The specific implementation process is as follows:

[0050] The key point of this embodiment is that the elastic material is deformed by using the disinfection cover 141, and when a certain position of the hemodialysis machine is covered (similar to a sucker forming a closed space), then the disinfectant will remain in the space formed by the disinfection cover 141, spray The sterilizing solution flows back into the liquid inlet cavity under the action of the suction force of the sterilizing pump 149, which further reduces the purpose of splashing the sterilizing solution everywhere, and at the same time, can also recover the sterilizing solution to a certain extent, reducing the loss of the sterilizing solution. Co...

Abstract

The invention relates to the technical field of medical equipment, and discloses a hemodialysis machine disinfection device which comprises a rack, a guide shaft is fixed to the rack, a disinfector is horizontally and slidably connected to the guide shaft, and the disinfector communicates with a pump assembly; a driving part is fixed on the rack, an output shaft of the driving part is provided with a ball screw rotationally connected with the rack, and a nut seat of the ball screw is fixedly connected with the sterilizer; the device further comprises a power part. An angle shaft is fixed to an output shaft of the power part and fixedly connected with the rack, an angle scale is rotationally connected to the angle shaft, a pneumatic part is arranged below the angle scale, and an output shaft of the pneumatic part is fixedly connected with the angle scale. The device is simple in structure, the position, height and angle of the sterilizer can be adjusted, and the hemodialysis machine can be conveniently sterilized.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a disinfection device for a hemodialysis machine. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapy methods for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. The blood contains electrolyte solutions with similar concentrations to the body. (Dialysate) Inside and outside the hollow fibers, material exchange is carried out through the principles of dispersion, ultrafiltration, adsorption and convection, to remove metabolic waste in the body, maintain electrolyte and acid-base balance; at the same time remove excess water in the body, and pass through The whole process of returning purified blood is called hemodialysis. [0003] After the hemodialysis machine is used, the shell and the pipeline system need ...
