Micro-positive-pressure protective hood with two-stage filtering air suction function

Abstract

The invention discloses a micro-positive-pressure protective hood with a two-stage filtering air suction function. The hood comprises a hood body, a window is arranged at the front part of the hood body, a tightening and fixing device is arranged at the lower part of the hood body, an air supply device is arranged outside the hood body, a primary filtering device is arranged in the air supply device, a two-stage filtering device is arranged in the hood body, a breathing tube is arranged between the two-stage filtering device and the air supply device, the two-stage filtering device is communicated with the air supply device through the breathing tube, and the hood body is further provided with an exhaust filtering device. According to the hood, the head of a medical worker can be protectedin all directions, a mask and goggles do not need to be worn, pressure sores and pressure marks are prevented from appearing on the face of a medical worker, the comfort of the medical worker is improved, the primary filtering device in the air supply device conducts primary filtering on air, the two-stage filtering device is arranged in the hood body to conduct two-stage filtering on the air, and therefore impurities, bacteria, viruses and the like in the air are fully filtered, and safety is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a micro-positive pressure protective headgear with secondary filtering and inhalation functions. Background technique [0002] At present, in order to protect themselves, most medical staff wear masks or goggles for protection. This method of protection is relatively limited, such as the head, ears and other parts cannot be protected, and it is cumbersome to wear. However, the process of putting on and taking off the traditional protective clothing is cumbersome and time-consuming, and the whole body is in the protective clothing, which is extremely hot. [0003] Therefore, the protective hood came into being. There is an air supply device outside the protective hood. The air supply device generally includes a motor, a fan, a primary filter, a lithium battery, and a circuit board. The air supply device sends air into the protective hood. However, this form of filtration ...

Problems solved by technology

[0002] At present, in order to protect themselves, most medical staff wear masks or goggles for protection. This method of protection is relatively limited, such as the head, ears and other parts cannot be protected, and it is cumbersome to wear. problems such as scars; while the traditional process of putting on and taking off protective clothing is cumbersome and time-consuming, and the whole body is in the protective clothing, which is extremely hot

[0003] Therefore, the protective hood came into being. There is an air supply device outside the protective hood. The air supply device generally includes a motor, a fan, a primary filter, a lithium battery, and a circuit board. The air supply device sends air into the protective hood. However, this form of filtration is less safe, and when the motor is damaged or the motor is out of power, if the motor fails or the battery is out of power, viruses or polluted air may still enter through the pipeline connected to the motor human body
