Abstract

A disposable manually operated sputum sucker is composed of elastic stand, corrugated pump, sucking tube and drainage bag, and features light weight, low cost and no cross infection.

Description

One disposable hand-operated sputum aspirator

The invention belongs to medical suction pump class.

What inhale the frequent use of expectorant in the medical treatment and nursing at present is the electromechanical suction pump, require to control at any time the suction size because of inhaling expectorant, also want gap operating, this makes electromechanical suction pump complex structure, troublesome poeration, the volume heaviness, price is higher, is not easy to pay a home visit use when rescuing, the product that also has foot-operated on a small quantity or manual type suction pump, the also more complicated valency height of infrastructure cost, so this two classes suction pump all is that many people use, sputum is relatively more sticking, cleaning and sterilizing is pretty troublesome, though each only tens cc of sputum that inhale if it is untimely to inhale expectorant, also can cause the serious consequence of death by suffocation sometimes.

The present invention seeks to manufacture and design a kind of small and exquisite spirit, cost is low, can accomplish the manual sputum aspirator of one person-time of use.

Accompanying drawing has been described one embodiment of the present of invention:

The present invention produces negative pressure be a ripple pump barrel 1., mantle valve pipe can be adopted in the pump two ends 2., pump barrel one termination sputum aspirator tube 3., 4. another termination drainage bag joins one outward

The type elastic shelf 5..

When loosening with hands During the type elastic shelf, elastic shelf opens, and elongates the ripple pump barrel, just can produce bigger negative pressure, sputum can be sucked, when holding when tight, elastic shelf is compacted, the compresses bellows pump barrel, sputum is inhaled by institute be pressed into drainage bag, like this repeatable operation when the suction sputum will be expired, just can be taken drainage bag and topple over or discard.

The ripple pump barrel adopts blow molding process to manufacture, and drainage bag can be used the heat seal craftwork manufacture, and production cost is very low,

The type elastic shelf can use repeatedly, manually sputum aspirator nearly weighs 100 grams, and suction can reach 400mmHg, 10 yuan of the about RMB of totle drilling cost, one person-time takes about 3 yuan, sputum aspirator just can be accomplished one person-time of special use like this, and both hygienic and convenient was operated also simple, general patient and family members can both operate, can alleviate medical personnel's work, as be used in type framework or 8 types or O type framework, also can be used for inhaling pus and blood and body fluid aspect.

Also do not have one person-time of sputum aspirator at present in the world, control takes much count of again to infectious disease now, so the present invention will have broad application prospects.

Claims

One disposable hand-operated sputum aspirator belongs to medical suction pump class.1, a kind of manual suction pump is characterized in that: affect the ripple pump barrel to produce negative pressure with elastic shelf.
2, suction pump according to claim 1 is characterized in that: elastic shelf is
Type, or 8 types adopt the mantle valve, are equipped with drainage bag.
3, suction pump according to claim 1 is characterized in that: elastic shelf adopts the mantle valve in type or O type framework, is equipped with drainage bag.
