Description

Technical Field

[0001] The utility model relates to the field of tracheal intubation, in particular to an intubation tube with a temperature and humidity detection function at the end. Background Art

[0002] At present, endotracheal intubation is a commonly used technical method in anesthesiology departments, emergency centers, and ICUs for endotracheal anesthesia, emergency treatment, and respiratory support treatment. When using this method, the temperature and humidity of the endotracheal tube outlet are not monitored or the temperature and humidity sensor is at the inlet end of the tube. The gas loses energy during the flow process and cannot be accurately measured, so an extrapolation algorithm is used to control the temperature and humidity of the gas.

[0003] The most suitable temperature for the human body is slightly higher than 25℃, which is 26-28℃. When the temperature starts to rise and exceeds 32℃, the human body begins to heat up and emotions fluctuate. In addition to temperature, humidity is also very important. When the humidity is greater than 95%, the human body feels very stuffy, perspiration on the body surface is blocked, heat dissipation is poor, the skin feels damp and sticky, and it is difficult to breathe, causing people to have to open their mouths to breathe. At the same time, the mood begins to become depressed. Of course, too low humidity is not good either. An overly dry environment can easily cause skin peeling. The most suitable humidity for human life is 45%-65%.

[0004] For patients with tracheal intubation, it is necessary to detect the temperature and humidity of the air outlet of the tracheal intubation. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] Combination Figures 1 to 4The embodiment of the utility model provides a cannula with a temperature and humidity detection function at the end, comprising: a cannula body 1; a temperature and humidity sensor 2 arranged at the air outlet end of the cannula body 1 (specifically at the air outlet); a sensor connector 4 connected to the temperature and humidity sensor 2 via a wiring harness 3; a wiring harness channel 11 for placing the wiring harness 3 is provided on the shell wall of the cannula body 1, and the outlet of the wiring harness channel 11 is connected to the inner wall of the cannula body 1.

[0026] In this embodiment, the cannula body 1 is made of conventional materials.

[0027] In this embodiment, the structure of the cannula body 1 is improved. The main improvement is that a wire harness channel 11 is provided on the shell wall of the cannula body 1. The inlet of the wire harness channel 11 is connected to the outer surface of the cannula body 1, and the outlet of the wire harness channel 11 is connected to the internal channel of the cannula body 1. Figure 2 and Figure 4 From the perspective of FIG. 1 , the outlet of the wiring harness channel is arranged close to the air outlet of the cannula body 1 .

[0028] One end of the wiring harness 3 is connected to the sensor connector 4 , and the other end is inserted into and placed in the wiring harness channel 11 , and extends out of the wiring harness channel 11 to be connected to the temperature and humidity sensor 2 inside the cannula body 1 .

[0029] Therefore, the temperature and humidity sensor 2 detects the temperature and humidity at the air outlet of the cannula body 1, and then transmits it to the controller through the wiring harness 3 and the sensor connector 4. The controller can actively adjust the temperature and humidity based on the temperature and humidity information; it can also provide information prompts to medical staff for manual temperature and humidity adjustments.

[0030] like Figure 1 The cannula with temperature and humidity detection function at the end also includes:

[0031] A standard conical connector 5 connected to the air inlet end of the cannula body 1 .

[0032] A standard conical connector 5 is used for connecting the cannula body 1 to an instrument.

[0033] like Figure 3 and Figure 4 The cannula with temperature and humidity detection function at the end also includes: an inflation valve 6; an air bag 7 mounted on the cannula body 1; a gas channel is provided on the shell wall of the cannula body 1, and the inflation valve 6 is connected to the inlet of the gas channel through the air guide tube 8, and the outlet of the gas channel is connected to the inside of the air bag 7.

[0034] In this embodiment, the gas channel and the harness channel 11 are two independent channels. When the cannula body 1 needs to be inserted into the patient's trachea, gas rushes in through the inflation valve 6 and enters the airbag 7 through the airway tube 8. The airbag 7 inflates in the patient's trachea, thereby fixing the cannula body 1 in the patient's respiratory tract.
