Abstract
This utility model belongs to medical instruments field, be specifically related to a kind of anaesthetic mask with waste gas recovering device, it is characterized in that comprising interior mask body, interior mask body is provided with the air inlet pipe of protrusion, outer mask body is positioned at the top of mask body, is fixed in air inlet pipe, forms gas sampling chamber between interior mask body and outside cover body, outside cover body is provided with the gas sampling pipe communicated with gas sampling chamber, and outside cover body is also distributed with multiple passage.This utility model has use safety, wear conveniently, waste gas reveals few advantage.When anesthesia sucks, use this utility model, the moment that waste gas is being got rid of just is inhaled in exhaust collector vessel, can not contaminated air, ensure that medical personnel's is healthy greatly.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of anaesthetic mask with waste gas recovering device.
Background technology
Anesthesia be when performing a surgical operation or be eliminate pain when carrying out diagnostic test operation, ensure patient safety, create the various methods that good surgical condition takes.The mode that current anesthesia sucks has endotracheal intubation to inhale face shield suction, when adopting face shield to suck, due to human body face complex structure, the edge of face shield can not fit tightly all the time patient facial region, waste gas easily spills from the edge of face shield, these waste gas can cause operation room air severe contamination, can cause harmful effect to doctor, nurse.At present in order to address this problem, generally adopt the way strengthening operating room inner air convection, although can deal with problems to a certain extent like this, these waste gas of suction that doctor, nurse still can be a small amount of.
Utility model content
When the purpose of this utility model is that solving prior art adopts face shield anesthesia to suck, the waste gas produced is many, operation room air pollution can be caused, affect the defect of medical care life health, a kind of anaesthetic mask with waste gas recovering device is provided, it is on the basis of prior art anaesthetic mask, be set to as dual-layer face cover structure, negative-pressure design between two face mask, just taken away in time when the waste gas that such inner face mask leaks enters between the face shield of both sides, waste gas can not spill second layer face shield, like this would not contaminated air.
This utility model is achieved by the following technical solution:
I.e. a kind of anaesthetic mask with waste gas recovering device, it is characterized in that comprising interior mask body, interior mask body is provided with the air inlet pipe of protrusion, outer mask body is positioned at the top of mask body, be fixed in air inlet pipe, form gas sampling chamber between interior mask body and outside cover body, outside cover body is provided with the gas sampling pipe communicated with gas sampling chamber, and outside cover body is also distributed with multiple passage.
Gas sampling pipe of the present utility model is connected with the exhaust collector vessel of prior art by pipeline, its pipeline arranges minipump, keep the negative pressure that gas sampling intracavity is certain, when waste gas spills from inner face covers edge, be pumped in time in exhaust collector vessel.
As a preferred version of the present utility model: the edge of interior mask body is provided with sealing gasket.
Interior mask body arranges sealing gasket, strengthens its sealing property, and the waste gas spilt is reduced to a minimum, then is collected by the negative pressure gas sampling chamber formed between interior mask body and outside cover body, effective.
As a preferred version of the present utility model: the edge of outside cover body is provided with sealing gasket.
This utility model has certain negative pressure all the time due to gas sampling intracavity, therefore generally outside covers edge can not arrange sealing gasket in principle, but at some in particular cases, when such as interior mask body does not establish sealing gasket, its air leakage is excessive, and outside cover body arranges sealing gasket also can play better effect.
As a preferred version of the present utility model: the edge of interior mask body and outside cover body is equipped with sealing gasket.
Interior mask body and outside cover body arrange sealing gasket simultaneously, and sealing effectiveness is best.
Sealing gasket is air bag.
Air bag described in the utility model is prior art, is also called air cushion, and it is arranged on the edge of mask body, is provided with inflation inlet, its objective is and fits closely with face, ensures sealing.
Sealing gasket of the present utility model preferably but be not limited to air bag, also can adopt any one sealing gasket that prior art is known.
Interior mask body planform of the present utility model is identical with the anaesthetic mask of prior art, is hemispherical face shield.
Outside of the present utility model its shaped slightly of cover body is greater than interior mask body, and it is completely coated.
This utility model has use safety, wear conveniently, waste gas reveals few advantage.When anesthesia sucks, use this utility model, the moment that waste gas is being got rid of just is inhaled in exhaust collector vessel, can not contaminated air, ensure that medical personnel's is healthy greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of Fig. 1 China and foreign countries mask body when being separated with interior mask body.
As shown in FIG.: 1. air inlet pipe; 2. cover body outside; 3. passage; 4. sealing gasket; 5. sealing gasket; 6. mask body in; 7. gas sampling pipe; 8. exhaust collector vessel; 9. minipump.
Detailed description of the invention
As shown in Figure 1 and Figure 2: hemispheric interior mask body 6 and outside cover body 2 fit together, outside cover body 2 is fixedly mounted on the top of air inlet pipe 1, gap is provided with between interior mask body 6 and outside cover body 2, its cavity is gas sampling chamber, outside cover body 2 is provided with 1 gas sampling pipe 7 and multiple passage 3, gas sampling pipe 7 is connected with exhaust collector vessel 8 by pipeline, and above-mentioned pipeline is provided with minipump 9.The edge of outside cover body 2 and interior mask body 6 is respectively equipped with sealing gasket 4, sealing gasket 5, and sealing gasket 4, sealing gasket 5 are air bag.
When this utility model uses, as the installation method of prior art, interior mask body 6 and outside cover body 2 are fixed on patient facial region, anesthesia suction-type, start minipump 9, the gas sampling chamber now between mask body 6 and outside cover body 2 keeps certain negative pressure, once interior mask body 6 edge has waste gas to spill, just be pumped to immediately in exhaust collector vessel 8, waste gas can not contaminated air.
