Problems solved by technology

[0005] In order to solve the problem of low cleaning efficiency caused by the need for repeated cleaning for a long time to clean the arterial puncture needle tube by the existing ultrasonic cleaner, the present invention provides a wall-standing arterial puncture needle tube cleaning device. The device is divided into cleaning area, needle tube installation area, liquid nitrogen treatment area and infrared heating area from bottom to top. The needle tube is installed on a support assembly in the needle tube installation area, and then the support assembly is driven downward by the lifting mechanism to enter Go to the cleaning area to be soaked and cleaned by alcohol, and then rise to the liquid nitrogen treatment area to be treated with liquid nitrogen gas, and then rise to the infrared heating area, where it is heated and sterilized by infrared rays to complete the cleaning and disinfection work, and finally continue to rise , taken out through the needle outlet on the top, the cleaning device combines alcohol cleaning and disinfection, which can greatly improve cleaning efficiency, reduce labor usage, and reduce cleaning costs

Embodiment 1

[0037] like figure 1 as well as Figure 10-14 As shown, a wall vertical arterial puncture needle tube cleaning device includes a closed casing 1 with a hollow chamber arranged against the wall, and a needle tube placement port 5 is opened in the middle of the side of the closed casing 1, and in the closed casing The top of the body 1 is provided with a needle tube outlet 105 and a cover plate I 106 for closing the needle tube outlet 105. The hollow chamber in the closed housing 1 is divided into an infrared heating area 104, a liquid nitrogen treatment area 103, and a needle tube from top to bottom. The installation area 102 and the cleaning area 101 equipped with alcohol, and these four areas are in the same vertical plane as the needle tube take-out port 105; several support assemblies 4 fixed on the movable plate assembly 6 for placing the needle tube are arranged in the hollow chamber , and the movable plate assembly 6 is driven by a lifting mechanism 2 to reciprocate bet...

Embodiment 2

[0048] This embodiment is an optimized improvement scheme made on the basis of embodiment 1, and its main structure is the same as that of embodiment 1, and the improvements are as follows: figure 1 , 4 , 5 and 6, each set of support assemblies 4 includes a support needle body 401 vertically arranged on the fixed base plate 601 of the movable plate assembly 6, and the top of the support needle body 401 penetrates into the needle tube to fix it, And there is a gap between the inner wall of the needle tube and the outer wall of the supporting needle body 401. The inside of the supporting needle body 401 has a hollow lumen 402, and its surface is densely covered with micropores 404 communicating with the hollow lumen 402. The micropores 404 refer to A small hole with a small diameter is generally 0.5-1.5mm in diameter. The bottom of the hollow lumen 402 communicates with the air blowing pipeline 602 provided in the fixed base plate 601. Opening, through which gas is blown into t...

Embodiment 3

[0057] This embodiment is an optimized improvement scheme made on the basis of embodiment 2, and its main structure is the same as that of embodiment 2, and the improvements are as follows: Figure 5-8 As shown, bristles 403 are distributed on the surface of the support needle 401 , and the length of the bristles 403 is 1.2-1.4 times the width of the gap between the inner wall of the needle tube and the outer wall of the support needle 401 .

[0058] In this embodiment, the length of the bristles 403 is limited, so that when the arterial puncture needle tube is inserted into the support needle body 401, the bristle 403 can be in an inclined state, thereby providing a certain elastic support for the arterial puncture needle tube, and also Can assist air bubbles to clean.

Abstract

The present invention discloses a wall-standing type arterial puncture needle tube washing device. The wall-standing type arterial puncture needle tube washing device comprises a closed shell body with a hollow chamber, the hollow chamber of the closed shell body is successively divided into an infrared heating zone, a liquid nitrogen processing zone, a needle tube arranging zone and a washing zone loaded with alcohol from top to bottom, a plurality of support assemblies fixed on a movable plate assembly for arranging a needle tube are arranged in the hollow chamber, and the movable plate assembly is driven by a lifting mechanism to reciprocate between the washing zone and a needle tube taking-out port. The needle tube is driven by the lifting mechanism to move downwards into the washing zone to be soaked and washed by the alcohol, then rise to the liquid nitrogen processing zone for a liquid nitrogen gas treatment, then rise to the infrared heating zone to conduct heating, disinfecting and sterilizing to finish washing and disinfecting work, and finally, the needle tube is taken out from the top needle tube taking-out port. The washing device combines alcohol washing, disinfection, etc., can greatly improve washing efficiency, also reduces labor utilization rate, and reduces washing costs.

Description

technical field [0001] The invention relates to an arterial puncture needle in the field of medical instruments, in particular to a wall-standing arterial puncture needle tube cleaning device. Background technique [0002] The body of the existing arterial puncture needle is a titanium alloy needle tube, one end is a puncture tip, and the other end is installed on a hand-held needle holder for puncture; after puncture is used, it needs to be cleaned and disinfected for reuse; [0003] When cleaning and disinfecting the needle tube of the arterial puncture needle, it needs to be removed from the needle seat first. The existing cleaning methods are generally ultrasonic cleaning, ultraviolet disinfection, etc., and then put it into a vacuum bag for vacuum storage for the next time. use. [0004] In the existing cleaning method, since the needle tube has a blood return port, when using a conventional ultrasonic cleaner for cleaning, it needs to be cleaned many times for a long ...
