Tracheal catheter indwelling depth detection device and tracheal catheter

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a tracheal catheter indwelling depth detection device which comprises a pressure sensing part arranged on the catheter wall of a catheter main body, a pressure sensing part comprising a shell, an elastic conduction piece, and a detection piece connected with the elastic conduction piece, and a recording part in signal connection with the detection part; in the process that the catheter main body extends into the human trachea, the shell is always in contact with the inner wall of the human trachea under the elastic action of the elastic conduction piece, and the pressure, acting on the shell, of the inner wall of the human trachea can be transmitted to the detection piece through the elastic conduction piece and detected by the detection piece; and the recording part is used for recording the pressure fluctuation detected by the detection part. According to the tracheal catheter indwelling depth detection device, the indwelling depth of the tracheal catheter in the trachea of the human body can be objectively and accurately judged. The invention further provides a tracheal catheter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endotracheal tube insertion depth detection device and an endotracheal tube. Background technique [0002] The endotracheal tube is a key medical device in general anesthesia, which is directly used in the patient's body to establish a temporary ventilation channel for the patient. Usually, there is a scale on the side wall of the endotracheal tube, which is convenient for the doctor to judge the depth of the tube, but in actual use, it is easy to count the bending part of the tube in the oral cavity into the total placement of the tube in the human trachea. Due to individual differences, the length of the bent part is also different, which further makes it impossible to objectively judge the insertion depth of the catheter in the trachea. Contents of the invention [0003] The purpose of the present invention is to provide an endotracheal catheter insertion depth d...
