Detailed implementation manners

[0029] As Figures 1 to 6 shown, a visible non-invasive in-vitro monitoring special-shaped tube provided by an embodiment of this application includes a main pipe body 2, a main joint 1 provided at the end of the main pipe body 2, a catheter 14 inserted into the main pipe body 2, a micro airway pressure sensor 121 and a micro airway flow sensor 131 provided inside the end of the catheter 14;

[0030] The other end of the micro airway pressure sensor 121 is connected with an airway pressure joint 12 through a cable, and the other end of the micro airway flow sensor 121 is connected with an airway flow joint 13 through a cable;

[0031] An oxygen delivery interface 4 is provided on the main joint 1;

[0032] The main pipe body 2 is hollow, the pipe wall of the main pipe body 2 is provided with a reinforcing wire 3 with a supporting function, the outer wall of the main pipe body 2 is penetrated with a body temperature interface 5, and the other end of the body temperature interface 5 is connected with a body temperature sensor 51; The main pipe body 2 is hollow, and the pipe wall is provided with a reinforcing wire 3;

[0033] The end wall surface of the main pipe body 2 is connected with an end-tidal carbon dioxide interface 6, an end-tidal carbon dioxide detection passage 62 is arranged along the pipe body of the main pipe body 2 to the front end of the pipe body, and through holes 61 for gas circulation are provided at the beveled mouth and the front outer wall at the front end of the main pipe body 2;

[0034] At the end of the main body 2, a camera USB interface 7 is connected to the pipe wall. The other end of the camera USB interface 7 is arranged at the pipe orifice of the main body 2, and a micro camera 71 is connected to the end of the camera USB interface 7. The camera USB interface 7 can be connected to a monitor 11 to display the images captured by the camera. While displaying the images, the monitor can also control functions such as taking pictures, video recording, and saving data.

[0035] An armored airbag 9 is connected to the inner pipe wall of the main body 2, and the other end of the armored airbag 9 is connected to an airbag indicating valve 8.

[0036] When not inflated, the armored airbag 9 shrinks inside the main pipe body and does not protrude from the pipe body, ensuring that the overall pipe body is flat and smooth. There is no visible annular shrinkage groove 91 in the non-inflated and shrunk state.

[0037] A blood oxygen connector 10 is arranged on the outer wall of the pipe wall of the main body 2. A stretch cloth 101 is sleeved on the outside of the main body 2. The other end of the blood oxygen connector 10 is connected to a blood oxygen sensor 102, and a blood oxygen clip 103 is connected to the side wall of the blood oxygen sensor 102.

[0038] A Murphy hole 21 is opened at the front end of the outer wall of the main body 2.

[0039] The micro airway pressure sensor 121 mainly monitors the airway pressure, converts the airway pressure into a differential signal, and transmits the measured value to the circuit MCU to accurately make inhalation and exhalation judgments. The micro airway flow sensor 131 monitors the patient's breathing condition and monitors the respiratory cycle.

[0040] At the tail end of the monitoring special-shaped pipe main joint 1, an airway pressure joint 12 and an airway flow joint 13 are respectively connected to the micro airway pressure sensor 121 and the micro airway flow sensor 131. The airway pressure joint 12 and the airway flow joint 13 are industry standard joints and can be connected to a compatible monitor to obtain airway pressure parameters: the highest airway pressure (Phigh), the average airway pressure (Pmean), the positive end-expiratory pressure (PEEP), and the respiratory frequency and other parameters.

[0041] The main joint 1 is provided with an oxygen supply interface 4. Through the oxygen supply interface, oxygen can be supplied when the special-shaped pipe main body is placed into the respiratory cavity, liberating the oral cavity passage and facilitating the implementation of surgeries through the oral cavity.

[0042] The pipe body of the main body 2 is hollow, and the pipe wall is provided with reinforcing steel wires 3 to strengthen the strength of the pipe body. The design of the reinforcing steel wires can ensure that the pipe body will not bend and close, ensuring oxygen supply safety.

[0043] At the beveled opening at the front end of the tube body and on the outer wall of the front end, there are end-tidal CO2 pores 61. The design of the end-tidal CO2 pores can play a role in capturing end-tidal CO2 in a timely manner, and is connected to a monitoring device through an end-tidal CO2 interface to read the parameters of end-tidal CO2;

[0044] The camera USB interface 7 can be connected to the display 11 to display the images captured by the camera. While displaying the images, the display can also control the functions of taking pictures, video recording, and saving data;

[0045] The camera 71 can guide the placement of the visual non-invasive intracavitary monitoring special-shaped tube in the natural cavity under full visibility, and can monitor the physiological conditions of the cavity in real time after the placement of the tube is completed, and promptly handle the detected abnormal conditions to avoid surgical risks;

[0046] At the end of the main tube body 2, the tube wall is connected with an airbag indicating valve 8, which extends along the tube body to the front end of the tube body and is connected to the armored airbag 9. When the armored airbag 9 is not inflated, it contracts inside the main tube body and does not protrude from the tube body, ensuring that the overall tube body is flat and smooth. When the tube body is inserted into the natural cavity, it will not cause blockage due to the protrusion of the airbag, enabling the tube body to be smoothly inserted into the cavity and avoiding cavity damage;

[0047] When the armored airbag 9 is in the non-inflated and contracted state, a circular contraction groove can be seen. The contraction groove pre-shapes the airbag. After the armored airbag 9 is inflated and expanded, it can help the tube body to be fixed without displacement. When deflating and withdrawing the tube, it also ensures that the armored airbag 9 can contract as a whole according to the pre-shaped contraction groove, ensuring that the armored airbag 9 is completely hidden inside the tube body without protrusion, facilitating the withdrawal of the tube without trauma;

[0048] At the corresponding position of the blood oxygen sensor 102, there is a blood oxygen clip 103. When the blood oxygen clip 103 is closed, it aligns with the optical device of the sensor, ensuring that there is no gap during blood oxygen data collection, making the collected data accurate and effective. The blood oxygen sensor 102 is used to collect blood oxygen saturation, uses infrared light as the emission light source, tests the light intensity through tissues, and obtains signals of SPO2 value and pulse rate through spectral recognition;

[0049] The design of the Murphy hole ensures that oxygen is more fully and sufficiently input into the airway during oxygen delivery and that the oxygen pressure can be promptly relieved, keeping the air pressure value at a safe level.

[0050] In this embodiment, as Figures 2 - 6 shown; the micro airway pressure sensor 121 and the micro airway flow sensor 131 are connected as a whole;

[0051] The main joint 1 is rotatably connected to the end of the main tube body 2, and the rotation angle range of the main joint 1 is 0° to 360°;

[0052] The catheter 14 is designed to be movable, facilitating the adjustment of the detection position of the sensor during monitoring to ensure the requirements of monitoring alignment and obtain accurate detection parameters;

[0053] At the end of the main body 2 of the catheter, a body temperature interface 5 is connected, and the other end of the body temperature interface 5 is connected to a micro body temperature sensor 51;

[0054] The body temperature interface is connected to the monitoring device to perform real-time dynamic monitoring of the body temperature condition.

[0055] The micro body temperature sensor 51 belongs to a digital NTC resistive body temperature sensor, which can monitor the temperature between 25 - 45 degrees, with an accuracy of 0.1 degree, 16-bit temperature resolution, a power supply pressure range of 2.7V - 3.3V, and has a single temperature conversion and shutdown mode, greatly reducing power consumption;

[0056] The elastic cloth 101 is nested outside the blood oxygen sensor 102;

[0057] The Murphy's eye 21 is arranged at the front side of the airbag 9.
