Abstract

The invention discloses a condensate water counterflow prevention device of a respirator. The condensate water counterflow prevention device comprises a tee connecting part, a filtering part and a drying bottle, wherein the drying bottle is filled with a drying agent. The filtering part is arranged in the tee connecting part, the first port of the tee connecting part is connected with the drying bottle, and the second port and the third port of the tee connecting part are connected with an air pipe of the respirator. The filtering part is of a reverse pi shape and comprises a transverse filtering screen and two longitudinal filtering screens, wherein the two longitudinal filtering screens are perpendicularly arranged on the transverse filtering screen. The transverse filtering screen is located on the first port of the tee connecting part, the two longitudinal filtering screens are located on the second port and the third port of the tee connecting part respectively, and the filtering part is made of material with the water absorbing property. According to the condensate water counterflow prevention device, water vapor and formed condensate water in the air pipe of the respirator can be automatically adsorbed, so that the workload of medical staff is reduced, and the effect of preventing counterflow of condensate water can be guaranteed.

Description

[0001] technical field [0002] The invention belongs to the technical field of medical devices, in particular to a device for preventing backflow of condensed water of a ventilator. Background technique [0003] Ventilators are a medical device widely used in hospitals. When the ventilator is in use, condensed water will be formed in the pipeline. This is due to the condensation of the gas exhaled by the patient during breathing in the ventilator pipeline. If the condensed water is not treated in time, it may accumulate and flow back. If the backflow condensate is inhaled by the patient, it will cause infection and even death in severe cases. [0004] At present, the way to prevent the backflow of condensed water is to install a condensed water bottle at the lowest end of the ventilator pipeline to collect the condensed condensed water; at the same time, properly heat the ventilator pipeline to reduce the difference between the gas temperature in the pipeline and the room...
