Description

The portable manual sputum aspirator

This utility model belongs to vacuum extractor, particularly relates to a kind of manual sputum aspirator.

Existing sputum aspirator has electrodynamic type and form such as foot-operated, and volume more very much not is convenient for carrying, and especially this sputum aspirator many people reuse, and causes cross infection easily, do not conform to the requirement of modern medicine.

For achieving the above object, the technical solution adopted in the utility model is as follows: portable manual negative pressure sputum aspirator, and balloon ends is equipped with Non-return air valve, and a Non-return air valve links to each other with phlegm storage jar, is connected with phlegm suction hose on the phlegm storage jar.

For produce negative pressure in phlegm storage jar, Non-return air valve is equipped with at the two ends of air bag, and valve body links together with the retaining head, and ball-type body and spring are housed in the valve body.

This utility model is made up of phlegm suction hose, phlegm storage jar, air bag and two Non-return air valves, and simple in structure, cost is low, but patients use separately, not only made things convenient for patient also to avoid the cross infection of pathogenic bacteria.During use phlegm suction hose inserted patient throat, with hands compression bladder repeatedly, can be with the sputum sucking-off.

Below in conjunction with accompanying drawing and further specify novel by embodiment:

Fig. 1 is the structural representation of embodiment;

Fig. 2 is left Non-return air valve structural representation;

Fig. 3 is right Non-return air valve structural representation;

Embodiment: portable manual negative pressure sputum aspirator, the 1st, phlegm suction hose, it is identical with present commercially available sputum aspirator tube, and the 2nd, union joint, its end is fixed on the tank body of phlegm storage jar 3, and the other end links to each other with phlegm suction hose.The 4th, rubber pneumatic bag, I is left Non-return air valve, and rubber pneumatic bag links to each other with phlegm storage jar by left Non-return air valve I, and II is the right-hand member that right Non-return air valve is contained in air bag 4.The 5th, seal cover covers on phlegm storage jar 3.Fig. 2 is the structural representation of left Non-return air valve I, the 6th, left side retaining head, its end links to each other with air bag 4, the other end links to each other with left valve barrel 7, in the hole in the left valve barrel 7 spheroplast 9 is housed, spheroplast can be a steel ball, glass bead or baton round equal sphere body, spring 8 is equipped with on the right of spheroplast, and the left end of left valve barrel links to each other with phlegm storage jar 3.Fig. 3 is right Non-return air valve, and its structure and left Non-return air valve are basic identical, just is contained in the right-hand member of air bag.

The throat that during use phlegm suction hose 1 is inserted the patient, compel air bag 4 with hand, gas pushes to two ends, there is spheroplast 9 to stop in the Non-return air valve I of a left side, gas can not enter phlegm storage jar 3, gas is pushing away the resistance that spheroids 13 in the right valve barrel 11 overcome spring 12 and is moving right, discharge by air vent 14, air bag restores and produces negative pressure during openhanded opening, outside air and spring 12 are pushing away spheroplast 13 left with air bag and extraneous path partition, air can not the air inlet capsule, and the spheroid 9 in the left valve barrel 7 is pushed open by the air in the phlegm storage jar and entered air bag 4, compression bladder so repeatedly simultaneously, make phlegm storage jar become negative pressure, the sputum of patient throat will constantly be inhaled into phlegm storage jar, owing to the gravity of sputum falls into the bottom of phlegm storage jar 3, can not enter air bag, after the use seal cover 5 is opened cleaning.

This novel volume is little in light weight, is easy to carry, and makes things convenient for the medical worker to go out precious the use, because its cost low price is cheap, the patient is adapted separately, and therefore, this utility model should have certain social benefit and economic benefit.
