Abstract

The utility model relates to a gas mask used for three-protection medical rescue, which comprises a mask and a canister, wherein the outer side of the mask is fixedly connected with a liquid oxygen storage tank, and an oxygen supply pipe connected to the liquid oxygen storage tank leads into the mask. According to the utility model, an emergency treatment gas mask has a working mode of independent positive pressure air supply, and is suitable for being used for and rescuing the wounded with cardiopulmonary failure; and the gas mask not only ensures the positive pressure oxygen supply needed for the wounded, but also facilitates medical rescue workers to carry and use on site, is suitable for being used in field operations and three-protection medical rescues, and can also be used emergently under an anaerobic condition so as to ensure timely oxygen supply to the wounded.

Description

Three anti-medical science rescue breathing masks

Technical field

The utility model relates to a kind of respiratory protection equipment, specifically a kind of three anti-medical science rescue breathing masks.

Background technology

Coring make trouble that part comprises that afraid fear attack of coring and burst coring are made trouble thus etc., have suddenly and uncertain, can people's cardio-pulmonary function be caused serious injury, can be in the extremely short time causing death.Therefore, if can in time implement effective oxygen supply and drug treatment to the wounded in the gold therapeutic time of key, follow-up treatment activities such as CPR just can be played due effect.

Present employed first aid breathing mask is that the individual soldier uses breathing mask mostly, and this breathing mask adopts negative pressure to filter malicious air-breathing principle, is for resisting several traditional chemical warfare agents, using object to design with the personnel with normal respiratory function as chemical defence.Because this breathing mask is not considered factors such as gas casualty's cardiorespiratory failure and decreased respiratory function in design, and the setting of filter poison layer has increased the weight of the inspiratory resistance of breathing mask, therefore, use such breathing mask for the gas casualty, cause the phenomenon because of decreased respiratory function, air feed deficiency death by suffocation on the contrary easily by the person of rescuing.

Abroad generally be to adopt portable respirator, promptly utilize oxygen cylinder that oxygen is provided or by electric device air blast forced gas supply as malleation air feed survival kit.This portable respirator and appended apparatus of oxygen supply have that volume and weight is big, carry during field first aid and use defective such as inconvenience, particularly are unsuitable for the field first aid of the large quantities of wounded under field condition.

The utility model content

The purpose of this utility model just provides a kind of three anti-medical science rescue breathing masks, is not suitable for the problem of using breathing mask to give first aid to the solution gas casualty.

The utility model is achieved in that a kind of three anti-medical science rescue breathing masks, comprises face shield and canister, is fixedly connected with liquid oxygen storage tank in the outside of described face shield, and the oxygen supply pipe that is connected on the described liquid oxygen storage tank leads in the described face shield.

On described liquid oxygen storage tank, be connected to control valve so that regulate oxygen supply whether with the size of regulating oxygen-supplying amount.

Described oxygen supply pipe is connected with wireway in the described face shield.

The utility model adopts miniature liquid oxygen storage to combine with supply technology, utilizing liquid oxygen to discharge volatilization in closed container becomes and produces certain this principle of oxygen pressure in the process of gas, realization makes the first aid breathing mask have the mode of operation of autonomous malleation air feed, therefore is particularly suitable for using and giving treatment to the cardiorespiratory failure wounded; The volume of institute's dosing oxygen storage tank is little, in light weight, both guaranteed the recover positive pressure oxygen supply of necessary abundance of cardio-pulmonary function in the gold therapeutic time of the wounded after the nuclear, biological and chemical warfare agent is poisoned, made things convenient for medical aid personnel carrying and on-the-spot the use again this breathing mask.The utility model is suitable for using in field operations with in three anti-medical rescues, can solve existing breathing mask effectively cardiorespiratory failure, the decreased respiratory function class wounded are succoured disadvantageous problem, the use of also can under oxygen free condition, meeting an urgent need, guarantee in time to be suitable for rescue to the nuclear, biological and chemical warfare agent gas casualty under the special oxygen-free environment conditions such as subway to wounded's oxygen supply.

Description of drawings

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

The specific embodiment

As shown in Figure 1, this three anti-medical science rescue can be used the face shield of three conventional anti-breathing masks with breathing mask, be provided with canister 2 in the front portion of face shield 1, be provided with fixed band 4 in the both sides of face shield 1, the fixedly connected liquid oxygen storage tank 3 in the outside of face shield 1, be provided with control valve 6 on liquid oxygen storage tank 3, this control valve has the effect by gas circuit simultaneously.One end of oxygen supply pipe 5 and the control valve 6 on the liquid oxygen storage tank 3 join, and the other end leads in the face shield 1, and can be connected with the wireway in the face shield 1.

The utility model adopts miniature liquid oxygen storage mode, can be used on two kinds of first aid breathing mask and common breathing mask.Its key technical indexes:

1, weight 600 grams;

2, supply gas pressure 〉=1kp;

3, oxygen-supplying amount 〉=400L.

The utlity model has independently miniature feeder and malleation oxygen supply pattern, can replace the rescue pattern of the negative pressure suction-type of traditional breathing mask, can improve the wounded's treatment rate and survival rate after the use.The utility model also possesses malleation oxygen supply pattern and the automatic conversion of filtering malicious function, i.e. malleation oxygen supply pattern is automatically converted to autonomous negative inspiratory pressure pattern after ten minutes.The utility model can compatible multiple breathing mask, has embodied characteristics such as microminaturization, safe, reliable, light and practicality.
