Ventilated and temperature-adjustable isolation protective garment

Abstract

The invention discloses a ventilated and temperature-adjustable isolation protective garment which comprises a protective garment body and a fresh air mechanism connected to the outside of the protective garment body, and an air inlet end allowing external air to enter and an air supply end allowing purified air to be discharged are arranged on a shell of the fresh air mechanism. A filter element cavity, a heat exchange cavity and a fan cavity are sequentially arranged in an air channel between the air inlet end and the air supply end of a shell of the fresh air mechanism, the filter element cavity is filled with a filter element for filtering and purifying flowing air, and the heat exchange cavity is filled with a heat exchange bag for cooling / heating the flowing air in a heat exchange mode. And a miniature high-speed brushless fan for driving air to flow from the air inlet end to the air supply end is arranged in the fan cavity. Purified air entering the protective clothing body can directly exchange heat with the heat exchange bag efficiently, the heat exchange stroke is short, and therefore the forming structure of the fresh air mechanism is simplified and compact, the manufacturing cost is low, and wearing and carrying are facilitated.

Description

technical field [0001] The invention relates to medical isolation protective clothing, in particular to a protective clothing that basically isolates the protected personnel (usually epidemic prevention medical personnel) from the external environment in an infection environment such as an epidemic. Background technique [0002] Medical protective clothing is usually made of non-woven protective clothing materials with good airtightness, and is a jumpsuit structure that connects tops, sleeves, trouser legs, headgear, etc., and is often used in medical and epidemic prevention and control and other infection occasions Clothing, such as the clothes worn by nucleic acid testing staff for epidemic prevention and control in recent years. [0003] There are two main structural forms of common medical protective clothing. The main difference between the two is whether there is a protective structure on the front of the headgear. That is, the front of the headgear of a kind of medic...

AI Technical Summary

Problems solved by technology

[0006] First, the indirect heat exchange needs to improve the thermal conductivity of the ice box and the spiral coil on the one hand, and on the other hand, it needs to increase the delivery stroke of the purified air outside the ice bag, which will inevitably lead to an increase in the manufacturing cost of the fresh air mechanism, and will also lead to fresh air. The structural volume and weight of the mechanism increase, making it inconvenient to wear and carry;

[0007] Second, the spiral coil is used as a large-stroke conveying channel for purified air, resulting in a large flow resistance of the purified air, which requires a high-power fan with a large structural volume to drive it, which will inevitably increase the manufacturing cost of the fresh air mechanism from another perspective. It will also increase the structural volume and weight of the fresh air mechanism, making it inconvenient to wear and carry
