Description

A kind of breathing mask
Technical field
The utility model relates to medical respiration face shield field, is more specifically a kind ofly can effectively reduce bacterial virus by the spittle and airborne isolated form breathing mask.
Technical background
Existing Gas feeding breathing mask is mainly used in the various first-aid apparatuses, in lung ventilator, aerator or various medicinal atomized inhalator, main effect is oxygen or the medicine mist that guarantees to provide variable concentrations in certain space, for patient's incoming call, to reach the purpose of rescuing or treating.For the breathing that guarantees the patient smooth and easy, existing this type of breathing mask all is directly to be thrown in the air to patient's treatment of waste gas of breathing out, and because patient's face shape varies in size, the face of being close to the patient that general breathing mask can't be safe fully spreads the waste gas of exhalation around face shield.Therefore existing breathing mask can cause the pollution of surrounding air, if these type of high words of propagating the venereal disease poison of similar SARS, even can cause infection to the healthcare givers, even adopt the operation mouth mask to cooperate the method for oxygen mask to deal with problems fully, so existing Gas feeding respiratory surface is covered with bigger potential safety hazard.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of novel Gas feeding breathing mask, is guaranteeing that patient respiratory smoothly under the prerequisite, can carry out filtration treatment to waste gas, effectively reduces bacterium that the patient discharges and germ through waste gas diffusion around the face shield.
Further purpose of the present utility model provides a kind of face shield that can be suitable for various patient's shapes of face, make face shield in use can be close to patient's face, play the sealing effectiveness that effective resistance waste gas leaks, and the waste gas storage in the minimizing face shield space, keep the patient can suck the oxygen or the medicine mist of selected concentration.
The utility model mainly is achieved through the following technical solutions its goal of the invention.
The utility model provides a kind of breathing mask, comprises mask body and fixed structure, and positive outwards protrusion of mask body forms cage, it is characterized in that described cage is provided with air inlet, and the cage bottom is located at and is filtered out device of air.The function of breathing mask mainly is oxygen or the pharmaceutical gas that enough concentration is provided in certain space for the user, and fixed structure is used to guarantee that face shield is worn over user's the mouth and nose outside, and is close to user's face.Outwards the cage that protrudes can guarantee that the user has enough breathing spaces, and making to breathe does not have constriction, can guarantee for being in dyspneic patient that particularly its breathing is smooth and easy.The air inlet of cage is used to connect apparatus of oxygen supply or treatment lung ventilator, can guarantee the lasting supply of oxygen and pharmaceutical gas, and guarantee that its concentration reaches the treatment standard.Discarding that the user breathes out need just can enter in the air after filtering out device of air, filter out device of air and can filter most pathogen and bacterium, thereby reduced pollution to environment, also stopped to pass through the infection of air cross-infection and high-risk virus between the patient to the medical worker.
In order to make face shield have more ergonomics, breathing mask body making of the present utility model becomes to be up-narrow and down-wide three-dimensional taper, the curved protrusion of cage, the protrusion of arc can make the outer wall of face shield try one's best people's face, reduce the space in the face shield, help the rapid discharging of waste gas, the interior oxygen of face shield or the concentration of medicine mist are maintained.The mask body bottom is provided with a circle soft washer, and the soft washer shape cooperates with breathing mask bottom part body profile phase.Mask body can adopt plastics or the higher material of metal equal strength to make, be the structure that up-narrow and down-wide structure can well be fit to user face, soft washer adopts soft material to make, the bottom of mask body and user's face are sealed fully, solve general face shield and can't press close to face, had the shortcoming of gas leakage.Soft washer can be air cushion, is connected with the valve that is used to inflate, if find before using that the air in the soft washer is not enough, is not enough to play the effect of sealing, can inject air to soft washer by valve, with the pressure of maintenance soft washer and the stability of sealing.Soft washer for disposable face shield also can adopt one-time formed air cushion, need not valve.This design of breathing mask can allow the user dress face shield easily, and very comfortable, also helps the application in the first aid.
The air inlet described in the utility model outside is provided with the air inlet pipe connector, and the inboard is provided with Non-return air valve.The air inlet pipe connector is used to connect the steam line of oxygen supply equipment or lung ventilator, be mainly used in and fix and be sealed in air supply pipe on the air inlet, fixing preventing can be adopted grafting, clamping, spiral interface etc., or the known technical scheme that is tightly connected of other those skilled in the art.Non-return air valve is used for guaranteeing discarded can not the backflow by air inlet, and oxygen and pharmaceutical gas can enter in the cage by check valve, and the waste gas that the user breathes out then can't leak by check valve, has further improved sealing property of the present utility model.
Existing therapeutic equipment is to supply and patient's incoming call by pharmaceutical gas a bit, and to reach the purpose of treatment, for cooperating being suitable for of this type of medicine, the utility model is provided with sprayer on the air inlet pipe connector.Sprayer can atomize medicine and supply the incoming call with the patient again after air or oxygen mixes, and sprayer is located between air supply pipe and the air inlet pipe jockey, and the size that can regulate atomization quantity needs to be suitable for different treatment effects and purpose.
In order to be suitable for different users's head dummy, fixed structure of the present utility model comprises elasticity headband and headband length adjuster.Cooperation by headband and length adjuster can adjust the headband length that is suitable for the different users, to reach the purpose of optimal seal.Fixed structure also can be other form, as the structure of tack coat, by binding agent face shield is fixed in the user on the face, or other general fixed structures.
The utility model can also further be improved to portable construction, in the described air inlet outside oxygen memory is installed directly.The oxygen memory can be general oxygen bag or small-sized oxygen cylinder, makes application of the present utility model further expand, and goes for the medical worker or other need the staff of oxygen supply, or even general consumer.
The device of air that filters out described in the utility model can be following several structures:
First kind is to be made of gas outlet and filter course, and filter course is covered in a side of gas outlet fully, and is simple in structure, easily manufactured, generally is applicable in the disposable face mask structure.Second kind is that the described device of air that filters out is by inside and outside two-layer isolation cover plate and the filter course that is made of a plurality of small-sized ventholes arrangements, filter course is located at and is isolated between the cover plate, cover all small-sized ventholes fully, this structural entity is structural good, long service life can be made into the replaceable structure of filter course as required.The third is to filter out device of air by gas outlet and the filter chamber that is connected with the gas outlet, and the active material that is used for filtered air is housed in the filter chamber, and this form can be filtered polytype virus, makes waste gas be able to abundant filtration, is applicable to high-risk patient.
