Heating device for respirator

Abstract

The invention relates to a heating device for a respirator. The heating device comprises a temperature control circuit, an electric heating wire and a silica gel plate, wherein the temperature control circuit is connected with the electric heating wire which is embedded in the silica gel plate, and the silica gel plate is sleeved on the respirator. Compared with the prior art, the heating device for the respirator has the advantages of wide using range, safety, reliability, convenience in maintenance and capability of guaranteeing respiring smoothness of the respirator and the like.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device for a respirator. Background technique [0002] At present, in the pharmaceutical industry, there is a problem with the configuration of the respirator at the sterile exhaust port of the water for injection storage tank and accessory tank: the water vapor generated by the hot water in the tank will condense when it hits the surface of the cold and highly hydrophobic PTFE membrane, and affect Exhaust effect, serious tank deflation and broken phenomenon caused by poor breathing when starting the pump to draw water. And the state of the art in the prior art is: 1. the polypropylene membrane of respirator filter element can not influence exhaust because of the big hole, but the degerming effect is not good, has the possibility of infecting bacteria. 2. Although the filter element of the respirator uses a PTFE antibacterial membrane, if a bypass is added, the water vapor in the ta...

Problems solved by technology

[0002] At present, in the pharmaceutical industry, there is a problem with the configuration of the respirator at the sterile exhaust port of the water for injection storage tank and accessory tank: the water vapor generated by the hot water in the tank will condense when it hits the surface of the cold and highly hydrophobic PTFE membrane, and affect Exhaust effect, serious tank deflation and broken phenomenon caused by poor breathing when starting the pump to draw water

And the state of the art in the prior art is: 1. The respirator filter element uses the polypropylene film, because the hole is big and can not influence exhaust, but the sterilization effect is not good enough, there is the possibility of bacterial contamination

2. Although the filter element of the respirator is made of PTFE antibacterial membrane, if a bypass is added, the water vapor in the tank will be discharged directly from the bypass port, which is more likely to be contaminated
