Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of artificial ventilator with protector that is applied to emergency rescue.
Background technology
Sudden cardiac arrest is stopping suddenly and loss of consciousness of circulation due to a variety of causes and breathing, if the long period ceases breathing, health can not get oxygen, and the people will be dead, must promptly rescue.Cardio-pulmonary resuscitation is exactly a series of emergency treatments of taking at this emergency case, and artificial respiration wherein helps to hinder a kind of method that the patient recovers or continue to keep eupnea artificially.The measure of on-the-spot cardio-pulmonary resuscitation for any patient, all has bigger infringement, simultaneously, when practicing artificial respiration, owing to lack safety precautions, the deliverer tends to touch because of carelessness patient's air-flow, blood, mucus and antibacterial, virus, and cross infection is to some diseases.
Chinese patent description 200420098160.6 (Granted publication on February 22nd, 2006) discloses a kind of artificial ventilator, is made of air tube, last contact opening, following contact cover.Upper end at air tube communicates and is connected as a single entity with last contact opening, is connected with down the contact cover on the air tube outer arm below the last contact opening.Though this kind artificial ventilator couples together deliverer and patient mouth to mouth with a root breath pipe, avoid the deliverer to follow the direct contact in patient oral cavity, but Returning flow is to deliverer's infection when can't effective isolation being exhaled by the patient, can not isolate the saliva that the deliverer breathes out and cause by patient's infection.
Chinese patent description 200420055167.X (Granted publication on January 18th, 2006) discloses a kind of life-kiss device, mainly is made up of thin-film body, and the back side of thin-film body scribbles viscose glue; The centre of thin-film body has pneumostome, and pneumostome is provided with drainage screen.Can directly thin-film body be sticked on patient's buccal during use, between patient and the deliverer by the drainage screen relief that practices artificial respiration.Though this kind artificial ventilator is provided with drainage screen, in the time of can't blocking the patient and exhale, reflux gas enters the deliverer oral cavity, and will stick on patient face to thin-film body before the relief, troublesome poeration not only, and hinder patient's back breathing of reviving.
The utility model content
The purpose of this utility model is exactly in order to overcome the above-mentioned shortcoming of present artificial ventilator; a kind of artificial ventilator is provided; this artificial ventilator is not only carried out life-kiss to the patient effectively; avoid the deliverer directly to contact the patient; but also the protective measure of anti-return and bacteriological protection can be provided, help the patient back of reviving simultaneously and breathe.
This utility model is achieved in that
The artificial ventilator that this utility model provides comprises loam cake, lower house, on be covered with air inlet, lower house is provided with the gas outlet, between loam cake and the lower house back-flow preventer is set, and is provided with the bacteriological protection face shield.
In such scheme:
Back-flow preventer can be to be with elastic gas barrier plate, and when the deliverer blew, institute's blowing gas stream entered from air inlet, produces certain pressure, and gas barrier plate is pressed down, and produces the space, and air-flow can enter loam cake, and the lower house of flowing through enters the patient oral cavity by the gas outlet.And patient's expiration produces a pressure that points to the gas outlet to gas barrier plate when the air inlet direction is discharged, and gas barrier plate is crushed on the air inlet baffle plate, blocks air inlet, prevents the backflow that the patient exhales.
Described gas barrier plate cross sectional shape is identical or close with the air inlet of loam cake, and area is greater than or equal to air inlet, makes that gas barrier plate can block air inlet effectively when the patient exhaled.
Gas barrier plate can be an elastic valve plate.
Gas barrier plate can be the silica gel sheet.
The bacteriological protection face shield is dismountable face shield, be provided with identical with a gas outlet cross sectional shape or akin emptying aperture in the face shield, the emptying aperture area can be less than or equal to the gas outlet area of section, make the bacteriological protection face shield can securely be sleeved on the gas outlet of lower house, this bacteriological protection face shield hides patient's face during the relief patient, the antibacterial, blood, the oral secretion contact deliverer that avoid the patient to discharge.
The sideline of the emptying aperture in the bacteriological protection face shield can be elastic rubber band, widens rubber band before the use earlier, than being easier to bacteriological protection face shield cover is installed on the gas outlet of lower house like this, and the gap is few.
Can be provided with at least one passage on the sidewall of lower house, this passage can give off lower house to patient's expiration, and when being hidden by the bacteriological protection face shield in patient face, the patient can pass through this passage incoming call ambient atmos.
Can be provided for pushing down the hold-down devices of tongue body in the lower house, when the patient is succoured, this hold-down devices is pushed down patient's tongue body, conveniently practice artificial respiration, this hold-down devices can be ligule or the flaky device that is provided with separately in the lower house, also can directly serve as with the gas outlet of lower house.
Be provided with filter membrane between the loam cake of artificial ventilator and the back-flow preventer, this filter membrane permeable watertight can filter deliverer's incoming call gas, avoids deliverer's the entering of oral secretion.
After such structure is adopted in artificial ventilator, not only can carry out life-kiss to the patient effectively rescues, the backflow that prevents patient's breath enters the deliverer oral cavity, can avoid simultaneously patient's blood, oral secretion, mucus splash to arrive the deliverer on the face, avoid the cross infection of virus, also help the patient back of reviving in addition and breathe.Like this, when satisfying the needs of on-the-spot cardio-pulmonary resuscitation, provide enough safety guarantee, eliminate deliverer's psychological burden, reach success in salvage preferably to the deliverer.And because the condition restriction of on-the-spot relief, this artificial ventilator can be made a kind of low cost and disposable operative installations collapsible, easy to carry.
