A kind of hemodialysis machine joint disinfection combination

Abstract

The invention discloses a connector sterilization combination for a haemodialysis machine. A connector is provided with a sterilization cover, an upper pipe opening of a sterilization pipe in the sterilization cover is blocked by a blocking cover, a first reset spring is fixedly arranged between the vertical section of a slide sheet and the outer wall of the sterilization pipe, the two side edges of a horizontal section of the slide sheet are respectively clamped into a position between the lower end surface of the sterilization pipe and a horizontal position limiting flange at the corresponding side, the horizontal section of the slide sheet is provided with a special-shaped through hole, when the sterilization cover covers the connector, an annular position limiting lug boss and an annular position stop lug boss are out of contact, a position limiting lug boss and a position stop lug boss are out of contact, at the moment, sterilization liquid can immerse the inner walls of a connection pipe, an outer pipe, an inner pipe and the sterilization pipe, and the outer wall of the inner pipe and the outer wall of the outer pipe positioned above an O-shaped sealing ring can be simultaneously immersed. The connector sterilization combination provided by the invention has the advantages that the connector is provided with the sterilization cover, so that the connector and the sterilization cover form sterilization combination, when the sterilization cover covers the connector, the sterilization liquid can reliably sterilize a position to be sterilized of the connector, the use safety can be ensured, and the manual interference like that in the prior art is not needed in the whole sterilization process.

Description

technical field [0001] The invention belongs to the field of hemodialysis machines, and in particular relates to a joint disinfection combination of hemodialysis machines. Background technique [0002] The connector is one of the important parts on the hemodialysis machine, which needs to be sterilized before use. During disinfection, the inner wall of each part of the joint is generally disinfected by pouring disinfectant, while the exposed section of the inner tube of the joint and the outer wall of the outer tube above the O-ring are often wiped and disinfected with a cotton swab dipped in iodine or disinfectant. [0003] The existing disinfection methods can reliably sterilize the inner wall of each part of the joint, but if the wiping disinfection method is used to sterilize the exposed section of the inner tube and the outer wall of the outer tube above the O-ring, it is very easy to have uneven disinfection, and even In some places, there is no disinfection, which le...

Problems solved by technology

[0003] The existing disinfection methods can reliably sterilize the inner wall of each part of the joint, but if the wiping disinfection method is used to sterilize the exposed section of the inner tube and the outer wall of the outer tube above the O-ring, it is very easy to have uneven disinfection, and even In some places, there is no disinfection, which leads to unreliable disinfection, and this defect is fatal to medical equipment; at the same time, the work efficiency of wiping and disinfection is relatively low, and automatic disinfection cannot be realized
