Description

An automatic spray type endoscope cleaning and disinfection tank

technical field

The invention relates to the technical field of medical instruments, in particular to an automatic spraying type endoscope cleaning and sterilizing tank.

Background technique

With the rapid development of the field of modern medicine, various medical devices that are used in conjunction with modern medicine have been born. Among them, endoscopy, as a routine examination, has been widely popularized. An endoscope is a lighted tube that goes through the mouth into the stomach or through other natural orifices into the body. The use of endoscopes can see lesions that cannot be displayed by X-rays, and can visually and accurately observe the lesions, which has an important auxiliary role for doctors.

According to the "Technical Specifications for Cleaning and Disinfection of Endoscopes" by the Ministry of Health, the cleaning and disinfection of endoscopes must include five steps: initial washing - enzyme washing - cleaning - soaking disinfection - final washing, most of which are carried out in the disinfection tank. Under normal circumstances, there will be a dedicated disinfection tank for each step, and cleaning solutions such as clean water, disinfectant, and enzyme solution are placed separately. If the disinfectant and enzyme solution come into direct contact with human skin, it may cause certain damage. The drainage outlet of the existing endoscope disinfection tank is generally set directly below the tank body, and the drainage pipe is directly sleeved or plugged into the drainage outlet. This installation method is less stable, and there is a risk of falling off during later use. It will cause the cleaning solution in the disinfection tank to leak out and cause certain damage to the operator.

There are also some sterilization tanks where the drain outlet is connected by a screw sleeve, that is, the drain outlet and the drain pipe are connected together by a screw sleeve. Due to the different sizes of the drain outlet and the drain pipe, the applicability of the screw sleeve connection is poor, which reduces its versatility and reduces the use range of the product. In addition, the use of screw sleeve connection requires a large force to tighten it, and the drain is generally set directly below the tank body, and the operator is often required to lie under the tank body during installation, which not only has certain dangers, It also seriously affects the installation progress of the installer, which is extremely inconvenient.

In order to solve the above problems, the inventor proposes an automatic spray type endoscope cleaning and disinfection tank, which is mainly a connection device for a drain pipe, and has the advantages of convenient installation, strong versatility and high installation stability, and avoids the prior art. Directly using plugging or socketing, which leads to the problem of unstable connection and possible leakage of cleaning solution, protects the safety of medical staff to a certain extent. In addition, the installation is simpler, which greatly improves the work efficiency of the installer.
