Description
Technical field
The present invention relates to a kind of protective garment, particularly relate to a kind of closed protective garment.
Background technology
For the medical personnel that treat, nurse the extremely strong infectiousness patient of infectiousness, protective garment is very important.If protect improperly, can make medical personnel be subjected to the threat of pathogenic microorganisms, even infect.In order to guard against infection, medical personnel can use the common vest of multilayer, and wear multilayer mouth mask and eyeshade.If but temperature height, when can not turn on the aircondition in the medical space, human body is perspired in a large number, eyeshade condenses because of sweat evaporation and causes the dimness of vision, the influence of multilayer mouth mask is breathed and the communication between medical personnel is obstructed, and medical personnel perspire in a large number, will certainly affect to its health, the lighter can occur dizzy, and collapse can appear in weight person.
There is a kind of medical protection apparatus in the U.S., and it is to adopt the conductor refrigeration heat radiation at head, by the steel cylinder oxygen supply, to keep the system of inner helmet malleation.This medical protection apparatus cost height need be connected with steel cylinder with conduit simultaneously, and medical personnel's treatment activity has been produced restriction; also there is a kind of transparent head-shield in China; it is a kind of protector by the oxygen cylinder air feed, but it only shields to head, and need carry oxygen bottle.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, positive-pressure closing formula protective garment is provided, medical personnel are hermetically sealed in protective garment, make medical personnel be in the state work down of pressure-fired, effectively stop outside pernicious gas to enter in the protective garment, it is unobstructed that the user is breathed, motion freely, also can make the user reduce perspiration, overcome that medical personnel perspire and the eye-blurred and the communication that cause are not smooth, the deficiency that physical consumption is many.
Technical scheme of the present invention is summarized as follows.
Positive-pressure closing formula protective garment, comprise conjoined clothes, the air cleaning induction system, power supply, gripper shoe, described air cleaning induction system comprises cover plate, protective cover, gas delivery system, cleaning system, deflector, described protective cover is arranged on the middle part of cover plate, inboard and described gas delivery system below the described cover plate, deflector connects, described cover plate lower outside is connected with described cleaning system, described gas delivery system comprises motor, blower fan, described motor is connected by lead with described power supply, described cleaning system comprises filter course, the deactivation layer, at least one deck in the adsorption layer, described cleaning system bottom is connected with described gripper shoe, described air cleaning induction system is arranged on the conjoined clothes, described conjoined clothes is provided with the air-out passage, and making the pressure in the protective garment is 1～100mmH
2O.
Described motor is a micromachine, and described blower fan is one of axial flow blower, air blast, micro-air compressor.
Described filter course is for meeting N95 or other material of N99 filtrate level.
The described N95 of meeting or other material of N99 filtrate level are one of gauze, nonwoven, activated carbon felt.
Described deactivation layer is solid-state or liquid hyperoxia voltinism material, and described hyperoxia voltinism material is fixed on the carrier.
Described adsorption layer is one of active carbon, calcium chloride, activated carbon felt, ion exchange resin, molecular sieve.
Described air-out passage is provided with the micropore damping material, and described micropore damping material is check valve or one-way ventilating material.
Described power supply is one of lithium battery, nickel-hydrogen cell, nickel-pneumatic cell, dry cell, lead-acid battery.
Positive-pressure type protective garment of the present invention has following advantage:
(1) can to make in the positive-pressure closing formula protective garment be 1～100mmH in the present invention
2The pressure of O, guarantee under the normal operating conditions gas by in the protective garment to outer discharging, except that normally the pumping into of Purge gas, the phenomenon that material is flowed in protective garment by the outside does not take place, avoid the pollution that medical personnel are caused.
(2) the Purge gas amount that enters protective garment reaches 1～100 times of human body normal demand amount, with the timely discharge of the unimpeded and metabolism gas that ensures respiration.
(3) by portable, battery powered, the protection system operate as normal is more than 8 hours.
(4) the disposable use of protective garment, cost is low.
(5) enter the absorption of the interior gas of protection through filtration and active material, degree of purification reaches existing medical respiration level of protection.
(6) protection of the present invention can be applicable to the protection of serious infectious disease, the protection of the infectious diseases such as SARS that cause as SARS virus.
(7) the present invention also can be used for chemical defence and prevents the harm that fire initial stage smog causes human body except that being used for medical protection.
