Description

The disposable oral cavity sputum aspirator

Technical field

This utility model relates to a kind of technical field of medical instruments, specifically the disposable oral cavity sputum aspirator.

Background technology

At present, carry out in respiratory tract, producing a large amount of sputums through regular meeting, as these sputums not being carried out treatment and the rehabilitation that effectively removing can influence children respiratory tract diseases in the children respiratory tract diseases treatment in hospital.The infant of especially just being born, the incidence rate of asphyxia of newborn is higher, like untimely processing; The cleaning failure will influence lifelong intelligence of neonate and quality, if then possibly lose the chance that neonate is survived; Now the sputum aspirator great majority that use of hospital are DYN dynamic, though effect is better, it is big to have a volume; The complicated characteristics of using inconvenience of complex operation cause cross infection easily, possibly cause use dangerous.

Summary of the invention

The technical assignment of this utility model is the deficiency that solves prior art, and a kind of child's special manual sputum aspirator simple in structure, disposable is provided.

The technical scheme of this utility model realizes by following mode; This disposable oral cavity sputum aspirator, its structure comprises sputum storing tube, sputum storing tube is communicated with sputum aspirator tube, conduit; Described sputum aspirator tube is inhaled expectorant end middle part and is had sputum suction hole; On the tube wall around the sputum suction hole, have auxiliary sputum suction hole, described conduit links to each other with negative pressure gasbag through first check valve, on negative pressure gasbag, also is provided with second check valve.

Described auxiliary sputum suction hole is provided with 3-5.

The beneficial effect that this utility model is compared with prior art produced is:

The disposable oral cavity sputum aspirator of this utility model simple in structure, easy to use offered sputum suction hole in the end of sputum aspirator tube, and 3-5 auxiliary sputum suction hole is set around the sputum suction hole, and it is effective to inhale expectorant, and remaining sputum is less, clean hygiene, and drain is unimpeded; On sputum storing tube, also be connected with negative pressure gasbag, so just can realize manually inhaling expectorant, no longer need electronic through conduit; Simple in structure; Easy to operate and volume is less, can not cause cross infection, and this utility model is disposable use sputum aspirator; Safety and sanitation are applicable to child's respiratory tract disease.
