Description

A semi-automatic cleaning and disinfection rack that is convenient for multiple use of medical needles

technical field

The invention relates to the technical field of medical devices, in particular to a semi-automatic cleaning and disinfection rack which is convenient for multiple use of medical needle tubes.

Background technique

When treating diseases in the hospital, the use of various disposable medical appliances will increase the cost of use, and these medical wastes cannot be centrally disposed of in time, and are easily purchased by illegal traders, repackaged and then sold for use. The needles sold in secondary packaging are generally not sterilized, so they carry a large amount of germs, which poses a great safety hazard to the public.

In order to prevent the medical needle tube from being reused without being sterilized for the second time, and to reduce the cost of medical use, it is necessary to design a device for sterilizing and cleaning the medical needle tube that can be used multiple times. The needle tube can be quickly sterilized when it is placed, so that it can be used directly next time.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a semi-automatic cleaning and disinfection rack that is convenient for multiple use of medical needles, so as to solve the problems raised in the above background technology.

In order to achieve the above purpose, the present invention provides the following technical solutions: a semi-automatic cleaning and disinfection rack that is convenient for multiple use of medical needle tubes, comprising a bottom plate, a disinfection cavity, a needle tube cylinder rack, and a disinfectant pool; the top of the bottom plate is fixed from left to right. A plurality of groups of sterilization chambers with the same rectangular structure are installed. The front side of the sterilization chamber is hinged with a chamber door in the middle part. The top right side of the sterilization chamber is connected with a vertical needle tube holder, and the top of the needle holder is connected with a Top mount with flared structure. The needle tube body to be cleaned and sterilized is vertically placed inside the needle tube tube holder, the top of the needle tube tube body is fixedly installed with the top eaves of the needle tube tube body, the interior of the needle tube tube body is provided with a vertical piston rod, and the top of the piston rod is provided with a vertical piston rod. The top plate of the needle tube piston rod is fixedly installed, and a group of disinfectant pools are arranged inside the disinfection chamber just below the needle tube holder. The air cylinder fixed on the upper side of the support frame is supported, and the lifting and lowering of the disinfectant pool and the clean water pool can be controlled by the air cylinder. By setting the first servo motor to a single rotation of the platen, the order in which the disinfectant pool and the clean water pool are located under the needle tube holder can be adjusted.

Two sets of pressure sensors are fixedly installed on the left and right sides of the top upper surface of the top seat. On the left side of the top of the top seat is a set of control boxes that are electrically connected to the pressure sensor.
