Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The present invention comprises three-way connector 1, filter element 2 and drying bottle 3, and filter element 2 is placed in the three-way connector 1; The first port of three-way connector 1 connects drying bottle 3 bottlenecks, and its second port and The third two ports are connected to the trachea 4 of the ventilator. The filter element 2 is in an inverted π shape, and includes a horizontal filter screen 2-1 and two vertical filter screens 2-2, and the two vertical filter screens 2-2 are vertically arranged on the horizontal filter screen 2-1 by bonding. The horizontal screen 2-1 is located at the first port of the tee connector 1, and the two vertical screens 2-2 are respectively located at the second port and the third port of the tee connector 1.

[0021] The tee connector 1 is made of non-toxic medical plastic, a...

Abstract

The invention discloses an anti-reflux device for condensed water of a ventilator, which comprises a three-way connection piece, a filter piece and a drying bottle with a built-in desiccant, the filter piece is placed in the three-way connection piece, and the first port of the three-way connection piece is connected to the drying bottle , the second port and the third port are connected to the trachea of ​​the ventilator; the filter is inverted π-shaped, including a horizontal filter and two vertical filters vertically arranged on the horizontal filter, and the horizontal filter is located at the first of the three-way connector. At the port, two longitudinal filter screens are respectively located at the second port and the third port of the three-way connection; the filter element is made of water-absorbent material. The invention can automatically absorb the water vapor and the formed condensed water in the trachea of ​​the ventilator, and can also ensure the effect of preventing the condensed water from flowing back while reducing the workload of medical personnel.

Description

technical field [0001] 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 [0002] 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. [0003] 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 temperat...
