Description

Shoulder type breathing protective head cover

Technical Field

The invention relates to a medical breathing protection device, in particular to a comprehensive medical breathing protection device.

Background

With the increasingly deep knowledge of respiratory infectious diseases, people have realized that the traditional medical respiratory protection device which only aims at protecting the mouth and the nose is insufficient in protection of respiratory infectious diseases; the need for a full-scale medical respiratory protection device that protects all of the wearer's head organs is therefore very acute.

The most common existing comprehensive medical respiratory protection device is a combined device which combines a mask, goggles (or a face mask) and a protective garment with a cap to form comprehensive protection for all organs of the head of a wearer. However, such a combined device has significant drawbacks in several respects:

first, the mask, the visor (or face shield), and the hooded protective suit are separate individuals and are not integrally constructed, and thus there is generally a protection hole at the junction.

And secondly, the periphery of the mask does not form a sealing effect, and only the splashed droplets on the front surface can be protected, but viruses flowing along with air cannot be protected, so that a protection leak exists.

Thirdly, the mask does not distinguish necessary breathing channels and other parts, but integrally adopts disposable filtering materials, so that the mask needs to be integrally discarded after being used once, and unnecessary waste is caused.

And the mask is made of opaque filter materials, so that the mask shields the face of a wearer, and the obstacles of facial recognition and expression communication of the wearer are caused.

Fifthly, the head of a wearer is tightly wrapped by the combined device of the mask, the goggles (or the face mask) and the protective clothing with the cap, so that the head of the wearer loses air circulation, and the wearing comfort is poor.

Sixthly, the mask and the goggles form protective sealing by closely attaching to the facial skin, and the facial skin of a wearer can be injured under the condition of long-term wearing.

The existing full-face type breathing protection device also belongs to a gas mask which is applied to special purposes such as chemical protection, dust prevention, smoke prevention and the like, and can be occasionally used as a medical breathing protection device. The protection device forms the protection measure into an integral structure to protect all organs of the head of a wearer, thereby avoiding the protection leak of the joint part; meanwhile, the protection device adopts the modularized filter element as a breathing channel, so that the whole device can be repeatedly used by partially replacing the filter element. However, this type of protection device has significant drawbacks in several respects:

firstly, such respiratory protection devices are generally used for special purposes, and therefore the filter elements thereof usually adopt canisters for corresponding purposes; because the cost of the canister is higher, the canister can be used for multiple times before being replaced, a wearer can possibly inhale viruses adsorbed in the canister in the last use process, and a protection leak exists when the canister is used as a medical breathing protection device, so the canister is generally not suitable for medical use.

Secondly, the filter element of the respiratory protection device is generally positioned at the mouth and the nose of a wearer, and the size of the canister is large, so that the face of the wearer is greatly shielded, and the obstacles of facial recognition and expression communication of the wearer are caused.

Third, because this kind of breathing protective device is used for meeting an urgent need under the special environment generally, therefore do not require taking measures to the comfortableness in the sealing means, feel sultry when wearing easily, is unsuitable to use as comprehensive medical breathing protective device for a long time.

Fourthly, such respiratory protection devices are usually worn in a head-supported manner, and since the canisters are generally heavy, they are prone to fatigue in the neck muscles when worn for extended periods.

For example, the chinese patent publication No. CN102641563A discloses an emergency escape respiratory protection hood, which comprises a transparent hood body, a window, a fixed head band, a mouth-nose mask, a high-efficiency air filter, a communicator and a neck fixing ring, and provides a small and light respiratory protection article for possible threat of sudden biological pollution. However, the respiratory protection device essentially belongs to a gas mask provided with a simple canister, is too high in cost as a disposable product, has a protection leak as a multiple-use product, and is not suitable for medical use; meanwhile, because no measure is required for the comfort in the sealing device, the patient feels sultry when wearing the device, and the device is not suitable for being used as a comprehensive medical breathing protection device for a long time.

The protective device forms protective measures into an integral structure to protect all organs of the head of a wearer, so that the protection leak of a joint part is avoided; meanwhile, the breathing protection device does not suck external air through the filter element, but arranges the breathing channel in the direction of the top of the head of a wearer, and sucks oxygen in an oxygen bottle carried with the wearer through a sealed pipeline, thereby realizing real fully-closed breathing protection and being particularly suitable for high-risk medical breathing protection environment; meanwhile, the protective device can provide a larger transparent area on the face of a wearer, and the face recognition degree of the wearer is improved. However, such a guard has significant drawbacks in several respects:

first, since the storage capacity of the canned oxygen cylinder is limited and it is difficult to use it continuously, it cannot be popularized as a comprehensive medical respiratory protection device in a normal environment.

Secondly, the breathing protection device has good whole tightness and limits the internal air circulation, so the breathing protection device is easy to feel sultry when being worn and is easy to form water mist in the transparent area of the face.

Thirdly, the breathing protection device is usually worn in a head supporting mode, the head movement of a wearer is limited, the neck muscle fatigue is easily caused when the breathing protection device is worn for a long time, and the cervical vertebra can be injured when the breathing protection device is serious.

In addition, the chinese patent publication No. CN111111040A discloses a "breathing protective hood", which includes a hood main body and an air filter module, and the hood protective measure is formed into an integral structure, and a disposable air filter element is used, so that the hood is suitable for medical use. However, such a respiratory protection device has a drawback that it is likely to feel stuffy when worn because it shields the wearer's face too much.
