Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for simulating the testing of endotracheal intubation for neurological monitoring. Background Technology

[0002] Neuromonitoring endotracheal intubation is used in thyroid surgery to monitor the status of the recurrent laryngeal nerve, specifically whether the nerve has been damaged during thyroidectomy. This monitoring process relies on the silver-plated wiring on the surface of the endotracheal tube, which is extremely thin, less than 0.05 mm thick. When inserting the endotracheal tube, the anesthesiologist often bends it at an angle to facilitate entry. However, the bending angle and position are often limited by the anesthesiologist's experience and habits, potentially damaging the silver-plated wiring on the tube's surface, though this damage is not visible to the naked eye. Damage to the wiring can affect nerve signal transmission and monitoring during surgery, potentially leading to surgical errors and patient injury. Utility Model Content

The clamping assembly is clamped at the upper end of the vertical section of the neuromonitoring endotracheal tube, and the end support is supported at the end of the horizontal section of the neuromonitoring endotracheal tube.

[0007] The horizontal section of the neuromonitoring endotracheal cannula is placed in a water tank and submerged in physiological saline, while the silver paste wiring on the vertical section of the neuromonitoring endotracheal cannula is connected to the monitoring equipment.

[0008] As a further improvement of this utility model, the locking position of the end support after rotation is used to control the bending shape of the neuromonitoring endotracheal tube, the locking position of the bending support after horizontal movement and rotation is used to control the bending point and bending shape of the neuromonitoring endotracheal tube, and the locking position of the clamping assembly after horizontal movement is used to control the bending angle of the neuromonitoring endotracheal tube.

[0012] As a further improvement of this utility model, the clamping assembly includes a first slide rail, a first slider, a first fixing block, a second slider, a first slide groove, a second fixing block, and a spring;

[0013] The first slide rail is horizontally installed on the wall panel, and the first slider slides on the first slide rail. The first slider has a horizontal first slide groove. A first fixing block and a second fixing block are installed at the left and right ends of the first slide groove. A second slider slides in the first slide groove between the first fixing block and the second fixing block.

After bending it to the required angle, a monitoring device is connected to this device for testing to check whether the endotracheal tube transmits signals. If the transmission is normal, it proves that the bending does not affect the silver plasma circuit, and the anesthesiologist can then insert the endotracheal tube into the patient's body. If the transmission is affected, the endotracheal tube may be damaged and needs to be replaced. This avoids injury to the patient caused by the doctor's misoperation during the operation.

Based on this, the locking position of the end support 17 after rotation is used to control the bending shape of the neuromonitoring endotracheal tube, the locking position of the bending support 13 after horizontal movement and rotation is used to control the bending point and bending shape of the neuromonitoring endotracheal tube, and the locking position of the clamping assembly after horizontal movement is used to control the bending angle of the neuromonitoring endotracheal tube.

[0027] Specifically:

[0028] The end support 17 of this utility model consists of an L-shaped tapered section and a connecting section. The tapered section is inserted into the end of the neuromonitoring endotracheal tube 23. The connecting section and the second support tube 16 are fitted onto the second bolt 15. The second bolt 15 is fixed to the wall panel 2 by the second nut 18. Specifically, the wall panel 2 has a circular hole for the second bolt 15 to pass through. After the second bolt 15 passes through the wall panel 2 from the back, the second support tube 16, the connecting section of the end support 17, and the second nut 18 are sequentially fitted onto the second bolt on the front of the wall panel. In use, loosening the second nut 18 allows the end support 17 to rotate around the second bolt 15 in the vertical plane; tightening the second nut 18 locks the end support 17 securely to the wall panel 2.

The device connector 21 is connected to the connection terminal 22 through the device connection line 20. The connection terminal 22 is used to connect the monitoring device.

[0033] The testing method for this utility model is as follows:

[0034] Before inserting the neuromonitoring endotracheal tube into the patient, the anesthesiologist tightens the upper end of the neuromonitoring endotracheal tube 23 between the second slider 6 and the first fixing block 5. The lower end of the pre-bent endotracheal tube is inserted into the end support 17, and physiological saline is added to the water tank. The angle of the end support 17, the horizontal position and angle of the bending support 13, and the horizontal position of the first slider 4 are adjusted to select the specific soaking area, bending shape, and bending point of the neuromonitoring endotracheal tube 23. After adjustment, the silver paste circuit connection line 25 of the neuromonitoring endotracheal tube 23 is connected to the device connector 21, and a monitoring device is connected to the connection terminal 22 for testing. The monitoring device is used to test whether the neuromonitoring endotracheal tube conducts signals. If the conduction is normal, it proves that the bending has no effect on the silver paste circuit, and the anesthesiologist can then insert the endotracheal tube into the patient. If the conduction is affected, the endotracheal tube may be damaged and needs to be replaced.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
