Breathing tube control valve and gas pipeline for connecting the control valve

Abstract

A breathing tube control valve and a gas pipeline for connecting the control valve, the control valve includes a housing, a valve part and a cover, the housing has a cavity, an air inlet pipe and an air outlet pipe, the cavity There is an inner tube inside the tube, which forms an inner cavity and communicates with the air inlet and outlet pipes. The valve part is set on the cavity tube, and the cover is closed on the valve part; wherein, the air inlet pipe of the shell is provided with a A pressure pipe joint with a small diameter leading to the inner cavity is used to connect a pressure pipeline, and the gas pipeline is used to connect with an air inlet pipe so that the pressure pipeline is built into the gas pipeline. In this way, the existing pressure pipeline installed externally can be changed to be installed in the same direction in the intake pipe pipeline, and the trouble and inconvenience caused by the externally connected type can be avoided in a built-in way.

Description

technical field [0001] The invention relates to a medical device, in particular to a breathing tube control valve and a gas pipeline used for supplying oxygen to patients. Background technique [0002] The breathing tube control valve generally used to supply oxygen to patients. In the existing design, it is used to measure whether the pressure value in the breathing tube is normal. The pressure line is a gas line connected by the control valve. One side is externally connected; when the pressure pipeline is connected externally between the breathing tube control valve and the ventilator, it is easy to cause inconvenience and troubles due to the external winding of the pipeline, especially if the pipeline is exposed. The risk of being cut or cut off by an external sharp knife will cause the pressure tube to fail to measure the pressure value in the breathing tube normally, which will be related to whether the ventilator can provide enough oxygen for the patient, thus indirec...

[0002] The breathing tube control valve generally used to supply oxygen to patients. In the existing design, it is used to measure whether the pressure value in the breathing tube is normal. The pressure line is a gas line connected by the control valve. One side is externally connected; when the pressure pipeline is connected externally between the breathing tube control valve and the ventilator, it is easy to cause inconvenience and troubles due to the external winding of the pipeline, especially if the pipeline is exposed. The risk of being cut or cut off by an external sharp knife will cause the pressure tube to fail to measure the pressure value in the breathing tube normally, which will be related to whether the ventilator can provide enough oxygen for the patient, thus indirectly affecting the patient safety of life

[0003] In addition, the existing breathing tube control valve often has problems such as excessive pressure difference between the inside and outside of the valve, which also causes noise from the valve.
