Medical positive pressure multifunctional helmet

Abstract

The invention discloses a medical positive-pressure multifunctional helmet, and belongs to the field of respiratory protection. In order to solve the problems that a baffle of a traditional positive pressure type respiratory protection device is fixed and cannot rotate, the air supply overflowing area is small, mist on a face screen is not prone to being removed and the like, the medical positive pressure multifunctional helmet is additionally provided with a secondary filtering layer and an overflowing layer for increasing the air overflowing area on the basis of an original fixed baffle; an original fixed baffle is designed to be a rotatable multifunctional baffle, so that air is directly blown to the face screen, the gas flowing area is increased, the gas inlet angle is changed, and the beneficial effects that the CO2 concentration reduction rate in the face screen is increased, the face screen defogs, the gas fluidity in the face screen is improved, and the wearing comfort of a human body is improved can be achieved.

Description

Technical field: [0001] The invention relates to the technical field of respiratory protection, in particular to a medical powered air-supply respiratory protection device. Background technique: [0002] Traditional self-priming masks have high breathing resistance, and long-term wearing will cause pressure sores on the faces of medical staff, and self-priming masks will be soaked by the water vapor generated by respiratory exhaust gas, which will reduce the filtration efficiency of the masks, thus affecting the use and wearing of medical staff. Comfort; and, the baffle above the forehead in the current powered air-supply breathing mask is fixed, and one or two vents are opened on the baffle, the air flow area is small, the air intake effect is poor, the air supply angle is fixed, and the exhaust gas produced by breathing Contains water vapor in the mask, which will fog up on the face screen and is not easy to remove; so the present invention designs a medical positive press...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems that the baffle plate is fixed and cannot be rotated, the air intake effect is poor, and the water vapor in the respiratory exhaust gas fogs on the face screen and is difficult to remove, and the like, and further provides a medical positive pressure multifunctional helmet; a medical positive pressure multifunctional helmet By designing a multi-functional baffle, the multi-functional baffle can be rotated 30° and can realize self-locking during the rotation process to prevent the baffle from slipping, thereby changing the intake angle. At the same time, a double-layer structure is set inside the multi-functional baffle One layer is the secondary filter layer, and the other layer is the flow-through layer, which realizes secondary filtration of air and large-area flow; realizes that clean air enters the inside of the face screen with a large area and multiple angles, and at the same time changing the angle of the multi-functional baffle can Let the air blow directly to the face screen to achieve the purpose of defogging the face screen
