Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a neuromonitoring endotracheal tube. Background Technology

[0002] Endotracheal intubation is a technique that involves inserting a tube into the human body through the surface or cavities of the body, primarily used to assist patients with mechanical ventilation.

[0003] An existing patent (publication number: CN 215426770U) discloses a multifunctional neuromonitoring endotracheal tube. A contact electrode, which is an electrode wire, is located within the tube wall between the cuff and the endotracheal tube connector. A notch is formed in the tube wall near the cuff to expose the contact electrode for contact with the patient's muscle tissue. The contact electrode is connected to an electrode interface for connecting to a neuromonitor. The cuff is a double-layered cuff connected to a cuff inflation interface. A thermocouple is positioned between the inner and outer layers of the cuff, close to the outer layer. The thermocouple wire passes through the tube body and connects to the thermocouple interface. The tube body also includes a camera, a suction tube, and a reinforcing guidewire. This enables multiple functions such as neuromonitoring, temperature detection, and visual operation.

[0004] During the aforementioned endotracheal intubation, the camera may be obstructed by liquid, which can easily affect the camera's field of view and cause inconvenience in operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a neuromonitoring endotracheal tube that allows for air blowing to clear the camera during endotracheal intubation, preventing obstruction of the camera's field of view and facilitating observation of the intubation process by staff. This solves the problem that existing endotracheal tubes may obstruct the camera's field of view due to liquid, leading to inconvenience in operation.

[0006] To achieve the above objectives, this application provides the following technical solution: a neural monitoring endotracheal cannula, comprising a cannula body, an insertion port at one end of the cannula body, an endotracheal connector at the other end of the cannula body, a protective sleeve fixedly connected to the inner wall of the cannula body, a camera wire fixedly connected inside the protective sleeve, a camera fixedly connected to one end of the camera wire, a camera interface fixedly connected to the other end of the camera wire, an air blowing tube fixedly connected inside the protective sleeve, the air blowing end of the air blowing tube being bent at a certain angle and facing the camera, an air blowing interface fixedly connected to the air inlet end of the air blowing tube, a heating wire fixedly connected inside the cannula body, a heating element fixedly connected to one end of the heating wire, the outer surface of the heating element being fixedly connected to the outer circumferential surface of the cannula body, and a heating interface fixedly connected to the wiring of the heating element.

[0007] The above solution addresses the issue that during existing endotracheal intubation, the camera may be obstructed by liquid, which can affect the camera's field of vision and cause operational inconvenience. By setting up an air blowing tube and air blowing interface, and positioning the air blowing end of the air blowing tube towards the camera, air can be blown into the camera during the endotracheal intubation process to clear the camera's field of vision, thus preventing obstruction and facilitating staff observation of the intubation process.

[0008] Furthermore, the heating wire is made of a soft material and is arranged in a spring-like shape.

[0009] Through the above scheme, the soft heating wire has high flexibility, which facilitates the bending operation of the tube body. The heating wire, which is set like a spring, has a large and uniform contact area with the tube body, which facilitates the overall heating of the tube body.

[0010] Furthermore, two reinforcing wires are fixedly connected inside the tube body. The reinforcing wires are made of stainless steel and are arranged in a spring shape. The reinforcing wires are arranged alternately with the heating wires.

[0011] The above solution uses stainless steel reinforcing wires arranged in a spring shape to increase the rigidity of the tube, prevent the tube from collapsing, and ensure smooth gas flow inside the tube.

[0012] Furthermore, the outer circumferential surface of the tube body is provided with a double-layered bladder, the double-layered bladder is connected to an inflation tube, the end of the inflation tube is provided with a bladder inflation port, and one end of the bladder inflation port is provided with a pressure indicator.

[0013] The above method allows the double-layered cuff to seal the trachea, and the pressure indicator can monitor the cuff pressure, ensuring that the cuff pressure remains within a safe range after intubation.

[0014] Furthermore, a first thermocouple is provided inside the double-layered sheath, and the first thermocouple is in contact with the outer layer of the double-layered sheath. The circuit of the first thermocouple passes through the tube body and connects to the first thermocouple interface.

[0015] The above method allows the first thermocouple interface to be connected to an external host, enabling the first thermocouple, which is in contact with the outer layer of the double-layered sheath, to detect the temperature of the tracheal tissue, thus facilitating staff to obtain the temperature data of the patient's tracheal tissue.

[0016] Furthermore, the tube wall is provided with four contact electrodes through electrode holes, and the other end of each contact electrode is connected to an electrode interface.

[0017] Through the above scheme, the electrode interface can be connected to an external nerve monitoring device, and then electromyography monitoring of the intralarynx muscles can be performed through contact electrodes during the operation.

[0018] Furthermore, the tube body is equipped with a suction tube inside, the suction port of the suction tube is located near the insertion port, and the other end of the suction tube is connected to a suction interface.

[0019] The above method can help patients remove sputum using a suction catheter, preventing sputum from affecting ventilation.

[0020] Furthermore, a second thermocouple is provided inside the double-layered sheath. The second thermocouple is in contact with the inner layer of the double-layered sheath, and the wires of the second thermocouple pass through the tube body and connect to the second thermocouple interface.

[0021] The above solution allows the second thermocouple interface to be connected to an external host, enabling the second thermocouple, which is in contact with the inner layer of the double-layer sheath, to detect the temperature of the tube body, ensuring that the heating temperature of the heating wire is moderate, and thus allowing the tube body to be kept at a suitable temperature for surgical operations.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This neuromonitoring endotracheal tube, by setting up an air inlet and air outlet, and positioning the air outlet of the air inlet towards the camera, allows for air cleaning of the camera during endotracheal intubation, preventing obstruction of the camera's view and facilitating observation of the intubation process by staff. The tube is heated and its temperature monitored by a heating wire, heating element, heating interface, second thermocouple, and second thermocouple interface, ensuring a suitable temperature and preventing discomfort to the patient during intubation due to low tube temperature. This solves the problem of existing endotracheal intubation methods where the camera may be obstructed by liquid, affecting the camera's field of view and causing operational inconvenience.

[0034] Please see Figure 1 , Figure 4 and Figure 5 An electric heating wire 8 is fixedly connected inside the tube body 1. An electric heating element 9 is fixedly connected to one end of the electric heating wire 8. The outer surface of the electric heating element 9 is fixedly connected to the outer circumferential surface of the tube body 1. The circuit of the electric heating element 9 is fixedly connected to an electric heating interface 10.

[0035] Please see Figure 4 and Figure 5 The heating wire 8 is made of soft material and is spring-shaped. The soft heating wire 8 has high flexibility, which makes it easy to bend the tube body 1. The spring-shaped heating wire 8 has a large and uniform contact area with the tube body 1, which makes it easy to heat the tube body 1 as a whole.

[0036] Please see Figure 4 and Figure 5The tube body 1 has two reinforcing wires 11 fixedly connected inside. The reinforcing wires 11 are made of stainless steel and are spring-shaped. The reinforcing wires 11 are interleaved with the heating wires 8. The stainless steel reinforcing wires 11, which are spring-shaped, can increase the rigidity of the tube body 1, prevent the tube body 1 from collapsing, and ensure smooth gas flow inside the tube body 1.

[0037] Please see Figure 1 and Figure 6 The outer circumference of the tube body 1 is provided with a double-layered cuff 12, and the double-layered cuff 12 is connected to an inflation tube 13. The end of the inflation tube 13 is provided with a cuff inflation port 14, and one end of the cuff inflation port 14 is provided with a pressure indicator 15. The double-layered cuff 12 can seal the trachea, and the pressure indicator 15 can monitor the cuff pressure, so that the cuff pressure is maintained within a safe range after intubation.

[0038] Please see Figure 6 The double-layered cuff 12 is equipped with a first thermocouple 16 inside. The first thermocouple 16 is in contact with the outer layer of the double-layered cuff 12. The wire of the first thermocouple 16 passes through the tube body 1 and connects to the first thermocouple interface 18. The first thermocouple interface 18 can be connected to an external host, enabling the first thermocouple 16 in contact with the outer layer of the double-layered cuff 12 to detect the temperature of the tracheal tissue, making it convenient for staff to obtain the temperature data of the patient's tracheal tissue.

[0039] Please see Figure 1 The tube body 1 has four contact electrodes 20 through electrode holes on its wall. The other end of the contact electrode 20 is connected to an electrode interface 21. The electrode interface 21 can be connected to an external nerve monitor, so that electromyography monitoring of the laryngeal muscles can be performed through the contact electrodes 20 during the operation.

[0040] Please see Figure 1 and Figure 2 The tube body 1 is equipped with a suction tube 22. The suction port of the suction tube 22 is located near the insertion port 2. The other end of the suction tube 22 is connected to a suction interface 23. The suction tube 22 can help the patient remove sputum and prevent sputum from affecting ventilation.

[0041] Please see Figure 1 and Figure 6 The double-layered sheath 12 is equipped with a second thermocouple 17 inside. The second thermocouple 17 is in contact with the inner layer of the double-layered sheath 12. The wire of the second thermocouple 17 passes through the tube body 1 and connects to the second thermocouple interface 19. The second thermocouple interface 19 can be connected to the external host, so that the second thermocouple 17 in contact with the inner layer of the double-layered sheath 12 can detect the temperature of the tube body 1, so that the heating temperature of the heating wire 8 is moderate, and thus the tube body 1 can be kept at a suitable temperature for surgical operations.

[0042] This embodiment of a neuromonitoring endotracheal tube, by setting up an air blowing tube 7 and an air blowing interface 25, and positioning the air blowing end of the air blowing tube 7 towards the camera 6, allows for air blowing to clean the camera 6 during the endotracheal intubation process, preventing obstruction of the camera 6's field of vision and facilitating observation of the intubation process by the staff. By setting up a heating wire 8, a heating element 9, a heating interface 10, a second thermocouple 17, and a second thermocouple interface 19, the tube body 1 can be heated and its temperature detected, ensuring that the temperature of the tube body 1 is suitable and preventing discomfort to the patient during intubation due to low temperature of the tube body 1. This solves the problem that in existing endotracheal intubation, the camera 6 may be obstructed by liquid, easily affecting the field of vision of the camera 6 and causing inconvenience in operation.

[0043] It should be noted that the insertion port 2 has a sloping structure.

[0044] The working principle of the above embodiments is as follows:

[0045] The air blowing interface 25 can be connected to an external air blowing device. During endotracheal intubation, if the camera 6 is obstructed by the patient's bodily fluids, air is blown into the air blowing tube 7 through an external air blowing device. The air blowing end of the air blowing tube 7 blows air onto the camera 6, clearing away the obstructing liquid and ensuring a clear view of the camera 6, facilitating the intubation operation. Before intubation, the heating interface 10 can be connected to an external power source, and the heating element 9 can activate the heating wire 8 to heat the tube body 1. The second thermocouple interface 19 can be connected to an external host, and the temperature of the tube body 1 can be transferred to the second thermocouple 17 through the inner layer of the double-layered sheath 12. The second thermocouple 17 can detect the temperature of the tube body 1 and display it through the external host. When the temperature of the tube body 1 is suitable, intubation can be performed, avoiding discomfort to the patient caused by a large temperature difference between the tube body 1 and the trachea during intubation.
