Abstract

The utility model relates to a sputum aspirator, wherein, a negative pressure device is composed of an elastic saccule and two one-way valves; the sputum aspirator is composed of a liquid storing bottle, a suction tube and the negative pressure device. The utility model has the advantages of small volume, convenient carrying, no power supply, sanitary performance, low cost, etc.

Description

The manual type sputum aspirator

This utility model relates to a kind of sputum aspirator, belongs to medical instruments field.

Sputum aspirator is the medical treatment device of indispensability when giving emergency treatment to a patient, anxious, heavy, when the danger patient rescues if untimely clearing pneogaster, with the foreign body sucking-off of expectorant, liquid or other semi-fluid shapes of oral cavity and throat portion, then patient will get clogged and can't breathe and dead.The sputum aspirator that uses in medical institutions is still many decades forward position usefulness old-fashioned device so far at present, is made up of vacuum pump and two carboies of heaviness.Though this old-fashioned sputum aspirator is respond well, two significant disadvantages are arranged: the one, very heavy, can't carry; The 2nd, under the non-transformer situation, can't use.Though the sputum aspirator tube that neonate is used solves some problems, need the medical worker to suck with mouth, this method is only applicable to neonate, and is not enough for Peter Pan and adult's degree of sucking, and do not meet hygienic requirements.

The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of light, volume is little, do not need power supply and meet the sputum aspirator of hygienic requirements.

The technical solution of the utility model is, forms hand movement underpressure equipment by a resilient bladder and two check valves, is equipped with liquid containing bottle and suction pipe again and just constitutes a kind of novel manual type sputum aspirator.

Below in conjunction with drawings and Examples this utility model is further described.

Accompanying drawing is a structural representation of the present utility model.

With reference to accompanying drawing, this utility model is by resilient bladder (1), check valve (2,3), and liquid containing bottle (4) and suction pipe (5) are formed; Resilient bladder (1) is provided with two openings (1a, 1b), and outgassing nonreturn valve (2) and breather check valve (3) are installed respectively, and breather check valve (3) is connected with the pipe (4a) that goes out of liquid containing bottle (4), and the air inlet pipe (4b) of liquid containing bottle (4) is then joined with suction pipe (5).

The structure of check valve (2,3) can be used bead spring or flapper-type etc., and available rubber of resilient bladder (1) or plastics etc. are made hollow ball.Suction pipe (5) and liquid containing bottle (4) are disposable product.

During use, suction pipe (5) is inserted to patient's bottleneck throat, pushes repeatedly and loosen resilient bladder (1), because outgassing nonreturn valve (2) can only be given vent to anger can not air inlet, breather check valve (3) can only can not be given vent to anger in air inlet, so form negative pressure device, sputum is drawn in the liquid containing bottle (4).

Advantage of the present utility model and good effect are:

(1) volume is little, and is light, is convenient for carrying;

(2) do not need power supply, any time, any place all can use;

(3) cost is low, is beneficial to promote the popularization use;

(4) meet hygienic requirements;

(5) because this device in the moment of extruding sacculus, has little air to spray from suction pipe, like this can be with the separation of the mucosa that holds, thereby can avoid electric suction apparatus to cause the damage of pharyngeal mucosa and hemorrhage because of continuing strong attraction.

This utility model is not limited to be applied in suction expectorant aspect.

Claims

1. a manual type sputum aspirator is characterized in that by resilient bladder (1), check valve (2,3), and liquid containing bottle (4) and suction pipe (5) are formed; Resilient bladder (1) is provided with two openings (1a, 1b), and outgassing nonreturn valve (2) and breather check valve (3) are installed respectively, and breather check valve (3) is connected with the pipe (4a) that goes out of liquid containing bottle (4), and the air inlet pipe (4b) of liquid containing bottle (4) is then joined with suction pipe (5).
