Adjustable anti-blocking sputum suction tube

Abstract

The invention provides an adjustable anti-blocking sputum suction tube, relates to the technical field of medical instruments, and solves the problem that auxiliary vibration of a barrel body cannot be realized in a linkage manner while sputum is sucked so as to achieve the purpose of shaking off sputum residues on the inner wall of the barrel body, mutual matching of a buffer protection structure and a grip structure cannot be realized, and the limiting of the insertion depth cannot be realized. The adjustable anti-blocking sputum suction tube comprises a barrel body, wherein a buffer structure is arranged on the barrel body, a grip structure is welded on the barrel body, and a telescopic gas cylinder is adhered to the barrel body. Bulges are welded to the top end surface of a supporting base in a rectangular array shape, and each bulge is of a semi-cylindrical structure; an elastic telescopic rod A is welded to a sliding block, and the head end of the elastic telescopic rod A is of a hemispherical structure; and the head end of the elastic telescopic rod A makes elastic contact with the top end surface of the supporting base, the elastic telescopic rod A is aligned with the bulges in position, the elastic telescopic rod A and the bulges jointly form a vibration structure of the barrel body, and therefore sputum residues on the inner wall of the barrel body can be shaken off.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and more specifically relates to an adjustable anti-blocking sputum suction tube. Background technique [0002] Suction devices are mainly electric multifunctional negative pressure suction devices and simple manual suction devices. The operation end needs to be connected to a suction tube or a sponge suction tube before use. [0003] For example, the application number: CN202020054309.X, the utility model relates to the technical field of medical equipment, and discloses an adjustable anti-blocking sputum suction device, including a liquid storage bottle, the upper end of the liquid storage bottle is threadedly connected with a screw cap, And the upper surface of the screw cap is communicated with a connecting cylinder, the side wall of the connecting cylinder is communicated with a sputum suction tube, and the side of the connecting cylinder away from the sputum suction tube is commu...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an adjustable anti-blocking sputum suction tube to solve the problem that the existing device has a single structure and cannot be linked to achieve auxiliary vibration of the barrel while sucking sputum. To achieve the purpose of shaking off the sputum on the inner wall of the barrel; moreover, the existing device does not have the buffer protection capability, and cannot realize the mutual cooperation between the buffer protection structure and the handle structure; finally, the existing device does not The problem of being able to limit the insertion depth
