Abstract

The utility model discloses a portable sputum aspirator, which is composed of a piston barrel (1), a piston (2), a cylinder rod (3), a uni-directional intake valve (11), a uni-directional outtake valve (10) and a rubber tube (9). The push-and-pull end of the cylinder rod (3) is provided with a push-and-pull handle of the cylinder rod (4); an air intake end of the piston barrel is connected with a subpressure bottle (7), and the subpressure bottle is connected with a sputum dissolver (8). The portable sputum aspirator has the advantages of not only simple structure, convenient operation and carrying, time and labor saving and pain relief of patients, but also cleanness and sanitation, which can be widely applied for salving critical patients suffering from respiratory tract obstruction.

Description

Portable sputum aspirator

This utility model relates to a kind of improvement of sputum aspirator, and a kind of specifically portable sputum aspirator is applicable to respiratory tract obstruction critical patient's rescue.

The critical situation of respiratory tract often takes place to block because of materials such as sputum and viscous secretions in clinical, if untimely clearing pneogaster will make patient die because of being choked to death.At present, cleaning patient respiration road adopts sputum aspirator mostly, negative-pressure type sputum aspirator, piston type sputum aspirator etc. is arranged, these sputum aspirators, because necessary bimanualness when using, inconvenient operation can not be inhaled expectorant continuously, delays rescue time, and volume is bigger, moves inconvenience, is not easy to family and uses.

The purpose of this utility model be to provide a kind of simple in structure, volume is little, can a hand operated, sanitation and hygiene and can inhale expectorant continuously, not only use, and be more suitable for the portable sputum aspirator that family uses for hospital.

This utility model is achieved in that this portable sputum aspirator is made of piston cylinder, piston, piston rod, breather cheek valve, unidirectional air outlet valve, suction expectorant sebific duct, push-and-pull end at piston rod is established the piston rod push-pull handle, piston cylinder air inlet termination negative pressure bottle, the molten expectorant device of negative pressure bottle water receiving.This portable sputum aspirator is also implemented by following measure: establish the arcuation hook in piston rod push-pull handle upper end, arcuation is hooked on the annulus of piston rod end, the support turning cylinder is established in piston cylinder and piston rod push-pull handle contact position, the piston rod push-pull handle is supported on the piston cylinder barrel, be provided with spring between piston rod push-pull handle and the hand holding handle, spring is installed in the spring base of hand holding handle, hold hand holding handle with one, press the lower piston rod push-pull handle, spring is compressed, piston rod push-pull handle pulling piston, gas in the negative pressure bottle by the breather cheek valve sucking-off between piston cylinder and the negative pressure bottle, is produced negative pressure in negative pressure bottle, unclamp the piston rod push-pull handle, the spring of compression is upheld, promote the piston rod push-pull handle, promote piston, the gas in the piston cylinder is passed through outside the unidirectional air outlet valve expelling tube by piston rod, the successive like this lower piston rod push-pull handle of pressing will produce successive negative pressure in negative pressure bottle; Negative pressure bottle is the container of a sealing, and the negative pressure bottle outlet side connects the piston cylinder inlet end; Fill water in the water-soluble expectorant device, inhaling the expectorant sebific duct inserts in the water of water-soluble expectorant device, the air inlet pipe of negative pressure bottle is inserted water-soluble expectorant device top, the mouth of pipe is in more than the water surface, soluble in water when sputum is sucked, prevent that sputum is bonded on the wall, the air inlet pipe mouth of pipe of negative pressure bottle should keep certain distance with the water surface, in case along with the suction of expectorant, the water surface rises, in the liquid negative suction bottle.Water-soluble expectorant device can avoid sputum to enter piston cylinder and negative pressure bottle cleaning with the back concomitant disinfection, meets the principle of health.

The utility model has the advantages that: compare with the sputum aspirator of present use, not only simple in structure, operation is easy to carry, time saving and energy saving, the misery that reduces patient, and sanitation and hygiene.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is that this utility model structure is along the axis cross-sectional schematic.

Make this utility model with reference to accompanying drawing 1.This portable sputum aspirator, constitute by piston cylinder 1, piston 2, piston rod 3, breather cheek valve 11, unidirectional air outlet valve 10, suction expectorant sebific duct 9, push-and-pull end at piston rod 3 is established piston rod push-pull handle 4, piston cylinder 1 air inlet termination negative pressure bottle 7, the molten expectorant device 8 of negative pressure bottle 7 water receivings.The arcuation hook is established in piston rod push-pull handle 4 upper ends, arcuation is hooked on the annulus 13 of piston rod end, piston cylinder 1 is established with piston rod push-pull handle 4 contact positions and is supported turning cylinder 12, be provided with spring 5 between piston rod push-pull handle 4 and the hand holding handle 6, spring 5 is installed in the spring base of hand holding handle 6, and negative pressure bottle 7 is the container of a sealing; Fill water in the water-soluble expectorant device 8, inhale expectorant sebific duct 9 and insert in the water of water-soluble expectorant device 8, the air inlet pipe of negative pressure bottle 7 is inserted water-soluble expectorant device 8 tops, and the mouth of pipe is in more than the water surface.
