Abstract
The utility model discloses a novel suction catheter, and belongs to medical apparatus and instruments. The novel suction catheter comprises a catheter body, wherein a joint is arranged at the front end of the catheter body; a negative pressure safety valve is further arranged at the front end of the catheter body; the tail end part of the catheter body is turned backwards from the inside of a catheter cavity to form a two-layer structure; and side holes in a spiral distribution are arranged on the external wall of the tail end of the catheter body. The suction catheter disclosed by the utility model has the advantages of rational structure design, convenience for operation, safety, good sputum suction effect and significant applicability.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of Novel sputum aspiration tube.
Background technology
The sputum aspirator tube that uses clinically normally is provided with an inlet at tail end, and itself and respiratory tract contact area are less, in the sputum suction tube that is difficult to be attached on respiratory tract, therefore the expectoration poor effect.Present sputum aspirator tube tail end is comparatively soft, and is more difficult when inserting respiratory tract; Some sputum aspirator tube is provided with side opening at the tail end sidewall, but because negative pressure is distributed inequality, the suction of side opening place's generation is less, is difficult to also guarantee that expectoration is thorough; In addition, present sputum aspirator tube does not have safety device, when negative pressure is excessive, is easy to respiratory system is damaged.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure that this utility model provides, and expectoration is thorough, handling safety, Novel sputum aspiration tube easily.
For realizing above-mentioned technical purpose, this utility model is realized by the following technical solutions: a kind of Novel sputum aspiration tube, comprise a body, and the body front end is provided with joint, it is characterized in that: the body front end also is provided with a negative pressure relief valve; The body end section returns backward in the tube chamber and turns over, and forms double-decker; Body tail end outer wall is provided with the side opening of Spiral distribution.
The utlity model has following beneficial effect: the body end section returns backward in the tube chamber and turns over, form an inlet on the top, and simultaneously also be provided with side opening on sidewall, guaranteed on the one hand to make sputum have enough channels to enter in suction pipe by the negative-pressure balancing at side opening and inlet place; Increased again on the other hand the intensity of body tail end, inserted in respiratory tract with convenient; Negative pressure relief valve can guarantee that in sputum aspirator tube, negative pressure is not less than safety value, avoids respiratory system is damaged; Its reasonable in design, easy to operate, safety, suction sputum is effective, has significant practicality.
