Description

A laboratory medical test tube sterilization and cleaning instrument

technical field

The invention belongs to the technical field of medical equipment, in particular to a sterilization and cleaning instrument for medical test tubes of a laboratory department.

Background technique

Laboratory department is the bridge between clinical medicine and basic medicine, including clinical chemistry, clinical microbiology, clinical

Sub-disciplines such as immunology, hematology, humoral science and blood transfusion. Test tubes, commonly used instruments in chemical laboratories, are used as reaction vessels for small amounts of reagents. They should be preheated before heating at room temperature or during heating, otherwise the test tubes will easily burst. The test tube is divided into ordinary test tube, test tube with branch, centrifugal test tube and so on. The specifications of ordinary test tubes are expressed in outer diameter mm × length mm, such as 15 × 150, 18 × 180, 20 × 200, etc. A flat-topped test tube is a round-bottomed flat-topped glass tube with a melted mouth. The flat mouth is convenient for sterilizing and killing bacteria at the mouth of the tube; the roll mouth test tube is a round bottom glass tube with a rolled edge or a round mouth. The rolled mouth or the round mouth is used to increase the mechanical strength, and at the same time, it is easy to hold and not easy to fall off; the fermentation test tube is a flat mouth and round bottom test tube with a thin diameter, a short diameter of 6mm, and a length of 30mm.

At present, the test tube used clinically is mainly composed of a glass tube body, which is cleaned after the patient is tested.

During the cleaning process, it is often necessary to add a cleaning agent for cleaning. During the cleaning process, the hands of the medical staff have to contact the cleaning agent, which is easy to cause hand pollution and the cleaning effect is poor.

Some laboratory test tube cleaning devices have also appeared in the prior art, such as one with the application number of 201610035040.9.

This Chinese patent discloses a laboratory test tube cleaning device, including a device shell and a test tube body, two ends of the device shell are respectively provided with support rods, the support rods are telescopic rods, and the upper end of the support rods is provided with a fixed rod, The central position of the fixing rod is provided with a driving motor, the driving motor is connected with the upper end of the cleaning rod, and the lower end of the cleaning rod is connected with the central position of the fixing plate. The fixing card is tightly connected with the test tube body. In the invention, the test tube body is respectively fixed on the fixing card, the length of the support rod is shortened, the test tube body is submerged into the cleaning agent, and the driving motor drives the test tube body on the fixed plate to rotate slowly, so that the cleaning agent can clean the test tube body. Although the device can clean the test tube, the device only cleans the test tube by rotating the test tube and using the cleaning agent, so the adhesion on the inner wall of the test tube cannot be cleaned, and the cleaning effect is not good.

In view of this, a laboratory medical test tube sterilization and cleaning instrument according to the present invention can simultaneously

The inner and outer walls of the test tube are brushed, and the effect is better, and a drying unit is added to dry the test tube.
