Problems solved by technology

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 depth of the catheter in the trachea

Embodiment 1

[0029] Seefigure 1 with figure 2 , the present embodiment provides a device for detecting the insertion depth of an endotracheal catheter 1, including: a pressure sensing part 12 and a recording part for being arranged on the catheter main body 11, the pressure sensing part 12 includes a shell, an elastic conductive part and an elastic conductive part The detection part connected with the detection part, the recording part is connected with the detection part signal; wherein, when the protruding end 111 of the catheter main body 11 starts to extend into the human body's trachea, the shell is in contact with the inner wall of the human body's trachea, and the shell is in contact with the inner wall of the human body's trachea. Under the action, it always keeps in contact with the inner wall of the human trachea. Since there are multiple raised tracheal rings on the inner wall of the human trachea, and the plurality of raised tracheal rings are evenly distributed along the axial...

Embodiment 2

[0036] See figure 1 , the present embodiment provides an endotracheal tube 1, including the endotracheal tube 1 in the first embodiment of the tube depth detection device, a catheter body 11, a tightening part 13 and a positioning part 14; wherein, the tightening part 13 is arranged on the catheter On the tube wall of the main body 11, the tightening part 13 is connected with the rigid circular platform ring 121 in the tube insertion depth detection device. After the tube insertion depth of the catheter main body 11 reaches the required depth or when the catheter main body 11 is used and removed from the human trachea , the tightening part 13 can make the hard conical ring 121 out of contact with the inner wall of the trachea of ​​the human body, avoiding that during the use of the endotracheal tube 1, the rigid conical ring 121 and the inner wall of the trachea of ​​the human body remain in a squeeze state for a long time to damage the inner wall of the trachea of ​​the human ...

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...
