Technical Field

The invention belongs to the technical field of medical protective equipment, relates to medical protective clothing, and particularly relates to a positive pressure type medical protective suit.

Background

Medical care personnel often wear the protective clothing for more than 8 hours in order to reduce the replacement of the protective clothing during an epidemic situation, and the medical care personnel are easy to syncope due to heat stress generated by the accumulation of human body heat; to prevent infection, medical personnel compress the N95 mask and goggles, causing severe facial pressure sores when worn for more than ten hours a day.

Disclosure of Invention

The invention aims to solve the technical problems that the existing protective clothing is airtight in the interior and too long in wearing time, so that heat stress, syncope and the like occur, and serious face pressure sores are easily caused by wearing a compression N95 mask and goggles, and provides a positive pressure type medical protective suit.

The technical means for solving the technical problems of the invention is as follows: a positive pressure medical protective suit comprises a medical protective suit, a medical protective hood and an air feeder, wherein the air feeder is hung outside the protective suit and is connected with a replaceable gas filter tank; the medical protective clothing and the medical protective hood are respectively internally laid with a plurality of ventilation branches which are communicated with each other, an air supply outlet of the air supply device is respectively communicated with the ventilation branches in the medical protective clothing and the medical protective hood through ventilation pipelines, and the medical protective clothing and the medical protective hood are respectively provided with at least one exhaust valve. Compared with the existing medical protective articles, the external gas is filtered by the gas filtering tank and then is sent to the interior of the medical protective clothing and the medical protective head cover by the air feeder, clean air is uniformly dispersed to the periphery of the body of medical workers through the ventilation branch circuits which are laid inside the medical protective clothing and the medical protective head cover and are communicated with the ventilation pipeline, heat and moisture generated in the working process of the workers can be timely discharged by the exhaust valves on the medical protective clothing and the medical protective head cover, the eardrum of the workers is prevented from being damaged by overlarge pressure in the protective face screen, the wearing comfort is improved, a micro-positive pressure environment is formed inside the medical protective clothing and the medical protective head cover, the gas and the virus outside can not enter, and the safety of the clothing is improved. The medical protective hood can replace a protective mask and goggles, and the problem that serious face pressure sores are easily caused by wearing a compression N95 mask and goggles is avoided.

The working principle of the positive pressure type medical protective suit provided by the invention is as follows: the method comprises the following steps that firstly, a worker wears a medical protective garment and then wears a medical protective hood, after the sealing is kept, an air supply device is opened, an air filter tank filters air, and the air supply device rapidly conveys clean air to the interior of the medical protective garment and the interior of the medical protective hood along ventilation branches in the medical protective garment and the medical protective hood through a ventilation pipeline; through discharge valve in time discharge heat and moisture, improve and dress the travelling comfort, the inside pressure-fired environment that has formed of protective clothing simultaneously, the gas and the virus of outside all can not come, have improved the security of medical protective suit. After the gas filter tank is used for a certain time, the gas filter tank can be replaced in time to ensure the air filtering effect.

Preferably, the plurality of ventilation branches inside the medical protective clothing are respectively distributed to the arm part, the leg part, the chest part and the back part of the protective clothing. This is for the air can reach each inside corner of medical protective clothing, avoids the leg of medical protective clothing or arm portion air not to circulate, has further guaranteed the travelling comfort of wearing of medical protective clothing.

Preferably, a plurality of vent holes are uniformly distributed on the vent branch. This is to better deliver clean air to the corners of the interior of the medical protective garment or hood.

Preferably, the medical protection hood comprises an outer hood, a transparent window is arranged on the outer hood, the lower end of the outer hood is connected with a skirt pendulum extending to the shoulder, a pulling rope used for keeping the medical protection hood sealed is arranged on the skirt pendulum, and a pig nose buckle for fixing is arranged on the pulling rope. The half-wrapping type structure is formed by the external head cover and the transparent window, the visual field can reach 100%, the pull rope is tensioned, then the fixing effect can be achieved through the pig nose buckle, the lower periphery of the skirt pendulum is fixed around the neck of a medical worker, and the inside of the medical protective head cover is in a closed state.

Preferably, the transparent window is made of PC material. The PC material has high light transmittance.

Preferably, six exhaust valves are arranged on the medical protective clothing and are respectively positioned on two arm parts, two leg parts, a chest part and a back part. This is to ensure more comprehensive exhaust, heat extraction and moisture removal.

Preferably, the air blower is tied outside the medical protective clothing through a waistband. This is for the convenience switch, makes the wearing process more convenient.

The invention has the beneficial effects that: compared with the existing medical protective articles, the design scheme of adopting positive pressure air supply for the first time is applied to medical protective clothing products, the problems of sultriness, syncope and the like generated in the wearing process of personnel can be effectively solved, external air is filtered by the air filter tank and then is sent to the interior of the medical protective clothing and the medical protective head cover by the air feeder, clean air is uniformly dispersed to the periphery of the body of medical personnel through the ventilation branch circuits which are laid in the medical protective clothing and the medical protective head cover and are communicated with the ventilation pipeline, the exhaust valves on the medical protective clothing and the medical protective head cover can timely exhaust heat and moisture generated in the operation process of personnel, the damage to eardrums, eyes and the like of the personnel caused by overlarge pressure in the protective face screen is avoided, the wearing comfort is improved, meanwhile, a micro positive pressure environment is formed in the interior of the medical protective clothing and the medical protective head cover, and outside air and viruses cannot enter, the safety performance of the protective suit is improved. The medical protective hood can replace a protective mask and goggles, and the problem that serious face pressure sores are easily caused by wearing a compression N95 mask and goggles is avoided.
