Abstract
The utility model provides a gas-cylinder sub-pressure absorbing device. A sub-pressure source of the device is communicated with a sub-pressure bottle with a pressure gauge; a pipeline is provided with a unidirectional air admission valve, a unidirectional exhaust valve and a safety valve; the sub-pressure source adopts the gas cylinder; compared wit the prior art, the gas-cylinder sub-pressure absorbing device has the advantages of reasonable design, simple structure, safety, reliability, convenient application, easy maintenance, no energy consumption, and the like, thereby having favorable popularization value.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of inflator formula negative pressure suction device of using of internal medicine.
Background technology
At present, the vacuum suction machine that hospital uses when being used for internal medicine and other aspects rescue critically ill patient, normally a kind of electrodynamic type suction pump of continuing to use for a long time, this suction pump quality is big, big energy-consuming, and when medical personnel give emergency treatment to a patient, can not normally use so that jeopardize patient's life because of having a power failure suddenly, in addition, in the rainy day or when running into other situation, motor can be electric because of the company of leaking, thereby burn machine or cause other dangerous situation because of connecting electricity; Just can the delay time at stop and repair or change motor, influencing normal rescue work and operation carries out, and causes patient death.
Summary of the invention
Weak point in the above background technology, the inflator formula negative pressure suction device that this utility model provides is a kind of simple in structure, with low cost, safe and reliable, quality is light again.
Inflator formula negative pressure suction device of the present utility model is realized in the following manner, the negative pressure source of this device with manometric negative pressure bottle be housed be connected, breather cheek valve and one-way exhaust valve are housed on the connection tube between negative pressure source and the negative pressure bottle, negative pressure source adopts the inflator formula, negative pressure bottle is provided with suction pipe, and observing tube and relief valve are arranged on the suction pipe; When the piston rod in the inflator when pressing down, one-way exhaust valve is closed, breather cheek valve is opened, and realizes negative pressure; When the piston rod in the inflator was pulled upwardly, breather cheek valve was closed, and one-way exhaust valve is opened, and realized the gas discharging, repeated with this; Gas is drawn out of in the negative pressure bottle, produces powerful negative pressure rapidly, and the negative pressure data are shown by Pressure gauge, when negative pressure acquires a certain degree, open switch, finish attraction work; If owing to operator carelessness or when can't reach predetermined value and make negative pressure value excessive, relief valve is opened automatically, extraneous air enters negative pressure bottle, makes a bottle interior negative pressure value reach desired effects; Can in observing tube, observe the situations such as color, quantity and viscosity that are attracted thing during attraction.
The beneficial effects of the utility model are: simple in structure, with low cost, safe and reliable, easy to use, light weight, do not expend the energy.
Description of drawings
Accompanying drawing 1 is the sketch map of inflator formula negative pressure suction device.
Description of drawings: handle 1, piston rod 2, pedal 3, connection tube 4, unidirectional air outlet valve 5, breather cheek valve 6, negative pressure bottle 7, suction pipe 8, nose conduit 9, observing tube 10, switch 11, relief valve 12, Pressure gauge 13.
The specific embodiment
Inflator formula negative pressure suction device of the present utility model is realized in the following manner, the negative pressure source of this device is connected with the negative pressure bottle 7 that Pressure gauge 13 is housed, breather cheek valve 6 and one-way exhaust valve 5 are housed on the connection tube 4 between negative pressure source and the negative pressure bottle 7, negative pressure source adopts the inflator formula, negative pressure bottle 7 is provided with suction pipe 8, and observing tube 10 and relief valve 11 are arranged on the suction pipe.When the piston rod in the inflator 2 when pressing down, one-way exhaust valve 5 is closed, breather cheek valve 6 is opened, and realizes negative pressure; When the piston rod in the inflator 2 was pulled upwardly, breather cheek valve 6 was closed, and one-way exhaust valve 5 is opened, and realized the gas discharging, repeated with this; Gas is drawn out of in the negative pressure bottle 7, produces powerful negative pressure rapidly, and the negative pressure data are shown by Pressure gauge 13, when negative pressure acquires a certain degree, open switch 11, finish attraction work; If owing to operator carelessness or when can't reach predetermined value and make negative pressure value excessive, relief valve 12 is opened automatically, extraneous air enters negative pressure bottle 7, adjusts that a negative pressure value makes it to reach desired effects in the bottle; Can in observing tube 10, observe the situations such as color, quantity and viscosity that are attracted thing during attraction.
This utility model is simple in structure, and with low cost, safe and reliable, easy to use, light weight do not expend the energy.
Claims (3)
1, a kind of inflator formula negative pressure suction device, the negative pressure source of this device with manometric negative pressure bottle be housed be connected, it is characterized in that being equipped with on the pipeline breather cheek valve, one-way exhaust valve and relief valve, negative pressure source adopts the inflator formula.
2, inflator formula negative pressure suction device according to claim 1 is characterized in that breather cheek valve and one-way exhaust valve are mounted on the connection tube between negative pressure source and the negative pressure bottle.
