Abstract

An oxygen detoxifying mask according to requirements is aimed at problems in the prior oxygen mask that because the oxygen or atomized gas continuously insufflated to an air tube is opposed to patient's breathing period, the breathing difficulties and discomfort of the patient are easily caused, and the oxygen and the atomized gas at the breathing period can blow the flying liquid particles with pathogen exhaled by the patient in every direction, so as to easily lead to environmental pollution and accelerate the virus spread etc. The mask adopts the technical measures that a breathing signal sensor that is connected with a breathing air steering control valve, a synchronous atomization drug doser is equipped on an oxygen supply tube, the upper end of an exhaled gas conductor is equipped with an adjustable pressure limiting valve and is connected with an outer sterilization exhaust piping, so as to realize the purpose that the oxygen, the drug dosing atomized gas and the exhaled waste as at breathing period can alternately work along with inhalation and exhalation of the patient. The mask neither affects the patient's breath, nor makes the flying liquid particles with pathogen exhaled by the patient, which also saves the oxygen and drugs, therefore, the mask is an ideal apparatus for preventing the infectious virus from spread such as SARS.

Description

Oxygen uptake toxin expelling face shield as required

Technical field: the utility model relates to a kind of gas mask.

Background technology: at present, in resisting SARS, the face shield oxygen supply that patient uses all is continuous oxygen supply or atomizing continuously, this just brings following drawback: 1. create antagonism in respiratory period because of just pressing to continuously to be blown into oxygen in the face shield and to breathe, so influence the discharge of carbon dioxide to a certain extent, cause patient respiration difficulty and uncomfortable; 2. even more serious be because of respiratory period oxygen blow the patient expired spittle that has pathogen to such an extent that splash everywhere, must cause room air pollution, accelerated the diffusion of virus spread; 3. waste oxygen.Therefore common face shield is badly in need of improving.4. open continuously atomizer is at the useless medicine of expiration phase wave, and the miniature water droplet of atomizing is good viral vectors and culture medium, and comparing droplet with air has certain humidity more to help the survival of virus.

The utility model content:

Task of the present utility model provides a kind of toxin expelling of oxygen uptake as required face shield, and it can be according to patient's physiological requirements oxygen uptake, and can avoid toxic gas is entered indoor polluting, and therefore is a kind of desirable utensil that cuts off the infectious victims breath.

Technical solution of the present utility model is: a kind of toxin expelling of oxygen uptake as required face shield, form by cover body oxygen supply pipe and expiratory air conduit etc., it is characterized in that, on cover body or oral cavity or nasal cavity or chest etc. the position of locating to detect breath signal be provided with sensor and be connected with the steering control valve that is located at the three-way pipe position by holding wire, be provided with the cover T-Ring that can be connected in expiratory air conduit upper end by valve with total waste gas sterilization discharge line.

In addition, in order to solve the similar problem of existing atomizer, to such an extent as to promptly it blows to the space to atomization gas in the exhalation phase and causes waste and pollution problem, also be provided with an air-breathing synchronous atomizer on the oxygen supply pipe, this atomizer control signal wire is connected with sensor.

Use of the present utility model and operation principle are, with the force-loose headband face shield is fixed on facial appropriate location, guarantee that sealing ring and skin of face are close to air tight and be advisable that telescopic escape pipe is connected by cover T-Ring and the outside waste gas discharge line of sterilizing.Begin when air-breathing as patient simultaneously, detect air-breathing commencing signal by sensor, the action of control steering control valve, open the oxygen supply pipe, and triggering atomizer work, close the expiratory air conduit simultaneously, make oxygen and atomization medicine enter respiratory tract by mask body smoothly, finish the intake period oxygen supply and through airway administration in patient's intake period; When patient began to exhale, sensor was received breath signal, and the control steering control valve is done the counter-rotating action, closes oxygen supply pipe and atomizer, opens the expiratory air conduit, and the autonomous breath of patient is successfully siphoned away by the suction pump of outside along the expiratory air conduit.When needs use continuous positive pressure oxygen supply or positive end expiratory pressure, can adjust the expiratory air voltage limiting value by the pressure limiting valve of adjustable in pressure and realize.

Compared with prior art, major advantage of the present utility model is: according to patient's physiological requirements oxygen uptake, neither influence patient respiration, can not make the spittle diffusion of the patient expired spittle that has pathogen and atomizer again, also save oxygen and medicine, can realize simultaneously the special treatment operation of some positive pressure oxygens, therefore be to prevent that SARS patient and other the infectious victimses are by breathing the desirable utensil with the viral pathogen diffusion.

Description of drawings: Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

As shown in the figure, this is oxygen uptake toxin expelling face shield as required, comprise cover body and the oxygen supply pipe that is being connected by three-way pipe and several parts of expiratory air conduit, wherein be provided with steering control valve 5 at the three-way pipe position, being provided with sensor 4 on cover body 1 is connected with steering control valve 5, the back that is positioned at the intake valve 8 of adjustable flow on oxygen supply pipe 2 is provided with air-breathing synchronous atomizer 6, this atomizer also is connected with sensor 4, and the pressure limiting valve 9 in expiratory air conduit 3 upper ends by adjustable pressure is provided with the cover T-Ring 7 that is connected with outside exhaust emission tube road.

The utility model is the first-selected apparatus of the SARS patient of lung ventilator of no use, is applicable to that also other the infectious victimses and general patient's treatment is used.
