Description

Technical Field

[0001] This utility model belongs to the technical field of endoscopic suction valves, specifically relating to a disposable low-friction endoscopic suction valve that can prevent cross-infection, has good sealing performance, low friction, and reduces hand fatigue for medical staff during surgery, thus increasing user comfort. Background Technology

[0002] Existing endoscopic suction valves include a rod, a housing, and a cap. The housing has a through hole in its center. The rod passes through the through hole, is secured to the cap by a spring, and includes a rod body. The lower end of the rod body has a water inlet. The side of the rod body has a water outlet. The water inlet and outlet are connected internally by the rod body. An annular sealing groove is located on the outer circumference of the lower end of the rod body. A conventional silicone ring for sealing is placed within the sealing groove. The rod and housing are made of metal. Existing endoscopic suction valves are generally reusable and require sterilization after each use. Incomplete sterilization can lead to infection of medical staff and patients, posing a significant risk. Furthermore, the metal material of existing endoscopic suction valves is expensive, inconvenient to use and maintain, increasing patient costs. Additionally, the high friction can cause hand fatigue for medical staff during surgery.

[0003] To address this, we have developed a disposable, low-friction endoscope suction valve that prevents cross-infection, has good sealing properties, low friction, reduces hand fatigue for medical staff during surgery, and increases user comfort. Summary of the Invention

[0004] The purpose of this invention is to provide a disposable, low-friction endoscope suction valve that can prevent cross-infection, has good sealing properties, low friction, and reduces hand fatigue for medical staff during surgery, thus increasing user comfort.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disposable low-friction endoscope suction valve, comprising a rod, a housing, and a cap; a through hole is provided in the center of the housing; the rod passes through the through hole, and after being fitted with a spring, is fixed to the cap; a silicone ring is fitted on the outside of the housing; the rod includes a rod body; an externally threaded post is provided at the upper end of the rod body, and a water inlet is provided at the lower end; a water outlet is provided on the side of the rod body; the water inlet and the water outlet are connected through the interior of the rod body; positioning grooves are provided in pairs at the upper end of the side of the rod body; hooks are symmetrically provided on the inner wall of the through hole of the housing; the hooks can be inserted into the positioning grooves and move up and down along them; when the housing moves to the lowest position, the through hole wall of the housing can block the water outlet.

[0006] Preferably, the cap has a threaded hole inside; the external threaded post cooperates with the threaded hole to achieve a fixed connection between the rod and the cap.

[0007] Preferably, the bottom of the silicone sleeve has crescent edges evenly distributed, and the silicone sleeve is a seal. The bottom of the sleeve can effectively fit the endoscope slot to form a bottom seal and play a sealing role.

[0008] Preferably, the rod is coated with a paraben, which makes it less likely for the endoscope to get stuck or unable to be pulled out during use.

[0009] Preferably, the rod is made of plastic and the silicone collar is made of silicone.

[0010] Compared with the prior art, this utility model provides a disposable low-friction endoscope suction valve, which has the following beneficial effects:

[0011] 1. The endoscopic suction valve in this invention is for single use only, which can effectively eliminate the risk of infection for medical staff and patients;

[0012] 2. The endoscopic suction valve in this utility model is made of plastic and silicone, which has a low cost and certain advantages in market promotion and product application, greatly reducing the medical costs for patients.

[0013] 3. The positioning slot can quickly locate the hook position of the casing, which can effectively prevent installation errors and improve production efficiency;

[0014] 4. Good sealing and low friction reduce hand fatigue for medical staff during surgery, increasing user comfort. Attached Figure Description
