Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a protective device for a nerve monitoring endotracheal tube. Background Technology

[0002] With the development of intraoperative nerve monitoring (IONM) technology, ventilation via IONM-monitored endotracheal tubes has become an important adjunct in head and neck surgery. This technology can monitor nerve signals in real time, helping surgeons to detect and avoid nerve damage during surgery, thereby reducing the risk of postoperative neurological dysfunction. Currently, the mainstream nerve monitoring tube in clinical practice is the IONM-monitored endotracheal tube (Trivantage), which has a conductive coating on its body as conductive electrodes. During surgery, one end of the IONM-monitored endotracheal tube is inserted into the patient's trachea, and the other end is connected to a threaded tube and anesthesia machine. The conductive coating on the tube contacts the glottis and is connected to a nerve monitor via wires, allowing real-time monitoring of the patient's laryngeal muscle activity, reflecting the function of the recurrent laryngeal nerve.

[0003] In clinical practice, although nerve monitoring catheters have good fit and thin walls, they still present certain difficulties in practical application. After draping sterile towels during surgery, the endotracheal tube is located below the sterile towels and is often compressed due to intraoperative manipulation, causing the endotracheal tube to kink. Although the use of face masks and / or endotracheal tube stents can alleviate the kinking of the endotracheal tube to some extent, the endotracheal tube will still be directly touched during intraoperative manipulation, causing it to kink. This not only causes ventilation obstruction and seriously threatens the patient's perioperative safety, but also forces frequent intraoperative adjustments to the tube, thus affecting the progress of the operation. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a protective device for endotracheal tubes used for nerve monitoring, in order to solve the technical problem in the prior art where the progress of surgery is affected by the kinking of the endotracheal tube.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A protective device for a neuromonitoring endotracheal tube, the protective device comprising a connecting base and a protective sleeve, one end of the connecting base being disposed on a patient's face mask or mouth, the other end of the connecting base being connected to the protective sleeve, and the protective sleeve being sleeved on the outside of the endotracheal tube;

[0007] The protective sleeve includes a sleeve body and an elastic support sleeve. The outer wall of the elastic support sleeve contacts the inner wall of the sleeve body, and the inner wall of the elastic support sleeve is used to fit over the tracheal tube to prevent external forces from acting directly on the tracheal tube.

[0008] Furthermore, the neuromonitoring endotracheal tube protective device also includes a positioning element, which is disposed between the cannula body and the endotracheal tube interface to fix the cannula body onto the endotracheal tube interface.

[0009] Furthermore, the positioning element includes two sector-shaped clamping pieces, both of which are disposed between the endotracheal tube interface and the cannula body, and a gap is provided between the two sector-shaped clamping pieces for the endotracheal tube interface to enter.

[0010] Furthermore, the fan-shaped clamping piece includes a connecting rod, a rigid clamping piece, and a flexible clamping piece. The connecting rod is disposed on the cannula body, the rigid clamping piece is disposed on the connecting rod, one end of the flexible clamping piece is disposed on the rigid clamping piece, and the other end of the flexible clamping piece is used to clamp the endotracheal tube interface.

[0011] Furthermore, the fan-shaped clamping piece also includes a support rib, which is connected between the rigid clamping piece and the flexible clamping piece to prevent the flexible clamping piece from deforming.

[0012] Furthermore, the endotracheal tube interface is provided with an interface protrusion ring, and the inner ring of the positioning member is sleeved on the interface protrusion ring.

[0013] Furthermore, the connecting rod is provided with a first slot and a second slot, the first slot being for inserting the sleeve body and the second slot being for inserting the rigid clamping piece.

[0014] Furthermore, the protective sleeve also includes radial reinforcing ribs, which are disposed within the sleeve body.

[0015] Furthermore, the sleeve body can be extended and bent.

[0016] Furthermore, the neuromonitoring endotracheal tube protective device also includes a flexible contact sleeve, which is fitted onto the connecting base to contact the mask or mouth.

[0017] Furthermore, the neuromonitoring endotracheal tube protective device also includes a bite pad, which includes an inner sleeve and an outer sleeve. The inner sleeve is fitted over the endotracheal tube, and the outer sleeve is fitted over the inner sleeve.

[0018] The technical solution of this utility model can achieve at least one of the following effects:

[0019] (1) The neuromonitoring endotracheal tube protective device of this utility model includes a connecting base and a protective sleeve. One end of the connecting base is placed on the patient's mask or mouth, and the other end of the connecting base is connected to the protective sleeve. The protective sleeve is fitted over the outside of the endotracheal tube. The protective sleeve includes a sleeve body and an elastic support sleeve. The elastic support sleeve has an outer outer wall and an inner inner wall. The outer outer wall contacts the inner wall of the sleeve body, and the inner inner wall is used to fit over the endotracheal tube to avoid direct external force acting on the endotracheal tube. The sleeve body is used to fit over the outside of the endotracheal tube to provide physical protection and prevent the endotracheal tube from being physically damaged by external forces during surgery. The elastic support sleeve is used to support the sleeve body and the endotracheal tube, so that the sleeve body... The endotracheal tube and the cannula are relatively fixed. The elastic support sleeve provides cushioning and reduces the external pressure on the endotracheal tube. The outer wall of the cannula contacts the inner wall of the cannula body, and the inner wall is used to fit the endotracheal tube. Through the cooperation of the elastic support sleeve and its outer and inner walls, the cannula body and the endotracheal tube are fixed as one unit. Combined with the fixing effect of the connecting base on the cannula body, the stress deformation capacity of the endotracheal tube is enhanced, making the endotracheal tube less prone to kinking. It can accommodate various surgical operation angles and body positions without the need for frequent adjustments to the endotracheal tube. Thus, it solves the technical problem in the existing technology where kinking of the endotracheal tube affects the patency of the respiratory circuit, leading to insufficient ventilation and requiring frequent manual adjustments that affect the progress of the operation.

[0020] (2) The endotracheal tube protection device for nerve monitoring described in this utility model further includes a positioning component. The outer ring of the positioning component is set on the cannula body, and the inner ring of the positioning component is used to fit on the endotracheal tube interface. The two ends of the cannula body are respectively fixed on the connecting base and the endotracheal tube interface. When an external force is applied to the endotracheal tube, the cannula body first bears the force and then transmits the force to the connecting base and the endotracheal tube interface, rather than acting directly on the endotracheal tube. Through the fixing effect of the positioning component, the risk of damage to the endotracheal tube caused by external force during the operation can be reduced, and the stability of the entire device is improved.

[0021] (3) The protective sleeve of the nerve monitoring tracheal tube of the present invention also includes radial reinforcing ribs to increase the rigidity and pressure resistance of the sleeve body, prevent the sleeve from being deformed or damaged by external pressure or collision during use, and ensure that the tracheal tube is not subject to external physical damage during the operation through the supporting effect of the radial reinforcing ribs.

[0022] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention.

[0039] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0040] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a protective device for a neurological monitoring endotracheal tube. The protective device includes a connecting base 1 and a protective sleeve 2. One end of the connecting base 1 is placed on the patient's mask or mouth, and the other end of the connecting base 1 is connected to the protective sleeve 2. The protective sleeve 2 is sleeved on the outside of the endotracheal tube 3. The protective sleeve 2 includes a sleeve body 21 and an elastic support sleeve 22. The outer wall 221 of the elastic support sleeve 22 contacts the inner wall of the sleeve body 21, and the inner wall 222 of the elastic support sleeve 22 is used to sleeve the endotracheal tube 21 to avoid external force directly acting on the endotracheal tube 21.

[0043] The connecting base 1 is located between the patient's mask or mouth and the protective sleeve 2, used to fix the part of the sleeve body 21 that is close to the human body. For example, the connecting base 1 can be made of silicone material. The connecting base 1 can be attached to the patient's mask or mouth by means of a strap. The endotracheal tube is located inside the protective sleeve 2 to prevent the endotracheal tube 3 from shifting or falling off during the operation and to protect the endotracheal tube from external pressure. Specifically, the protective sleeve 2 includes a sleeve body 21 and an elastic support sleeve 22. The sleeve body 21 is used to cover the outside of the endotracheal tube 3 to provide physical protection and prevent the endotracheal tube 3 from being subjected to external physical damage during the operation, such as damage caused by instrument collision or the operator's movements. The elastic support sleeve 22 has an outer wall 221 and an inner wall 222. The elastic support sleeve 22 is used to support the sleeve body 21 and the endotracheal tube 3, so that the sleeve body 21 and the endotracheal tube 3 are relatively fixed. The elastic support sleeve 22 is elastic and provides a cushioning effect to reduce the external pressure on the endotracheal tube 3. The outer wall 221 and the sleeve The inner wall of the main body 21 is in contact with the inner sleeve 222, which is used to house the endotracheal tube 3. Through the cooperation of the outer sleeve 221 and the inner sleeve 222, the cannula body 21 and the endotracheal tube 3 are fixed together. Combined with the fixing effect of the connecting base 1 on the cannula body 21, the stress deformation capacity of the endotracheal tube 3 is enhanced, making the endotracheal tube less prone to kinking. It can accommodate various surgical operation angles and body positions without frequent adjustments to the endotracheal tube. This solves the technical problem in the prior art where kinking of the endotracheal tube affects the patency of the respiratory circuit, leading to insufficient ventilation and requiring frequent manual adjustments that affect the progress of the operation. In addition, the stable placement of the endotracheal tube 3 within the protective sleeve 2 reduces friction between the endotracheal tube 3 and the cannula body 21, protects the outer surface of the endotracheal tube 3, and prevents damage to the tube or obstruction of nerve signal transmission due to friction. At the same time, the stable placement of the endotracheal tube 3 within the protective sleeve 2 helps maintain the function of the tube's nerve monitoring. The stable placement of the endotracheal tube 3 during the operation improves the overall safety and success rate of the operation.

[0044] An optional embodiment of this utility model, such as Figure 2 As shown, the protective sleeve 2 also includes radial reinforcing ribs. The radial reinforcing ribs are set inside the sleeve body 21, which can increase the rigidity and compressive strength of the sleeve body 21, and prevent the sleeve from being deformed or damaged by external pressure or collision during use. Through the supporting effect of the radial reinforcing ribs, it is ensured that the tracheal tube 3 is not subjected to external physical damage during the operation. For example, the radial reinforcing ribs are collar structures and can be made of stainless steel. The radial reinforcing ribs can be embedded in the sleeve body 21. The radial reinforcing ribs are set at equal intervals along the axial direction of the protective sleeve 2.

[0045] In one optional embodiment of this utility model, the cannula body 21 is extendable and shortenable and bendable; the cannula body 21 is extendable and shortenable so that the length of the cannula body 21 can be adjusted according to the length of the tracheal tube, and the cannula body 21 is bendable so that the cannula body 21 can be adjusted according to the degree of bending of the tracheal tube. Through the bending and extension functions of the cannula body 21, it is ensured that the tracheal tube 3 is not damaged by external physical force during the operation and its function remains intact. For example, the cannula body 21 is a retractable corrugated tube.

[0046] In one optional embodiment of this utility model, the neuromonitoring endotracheal tube protective device further includes a flexible contact sleeve 6. The flexible contact sleeve 6 is fitted onto the connecting base 1 to contact the mask or mouth. The flexible contact sleeve 6 is flexible and elastic, making it easy for the flexible contact sleeve 6 to be fitted into or removed from the connecting base 1. The flexible contact sleeve is used to surround the protrusions of the connecting base 1. The flexible contact sleeve can be made of liquid silicone or latex material, and can be adhered to the mask or mouth with medical adhesive tape.

[0047] An optional embodiment of this utility model, such as Figure 7 As shown, the neuromonitoring endotracheal tube protection device also includes a bite pad 7, which includes an inner sleeve 71 and an outer sleeve 72. The inner sleeve 71 is fitted over the endotracheal tube 3, and the outer sleeve 72 is fitted over the inner sleeve 71. The bite pad 7 can be attached to the flexible contact sleeve 6 and is removable. In specific applications, the bite pad 7 is placed between the patient's incisors to prevent the patient from biting down on the endotracheal tube 3. For example, the inner sleeve 71 can be made of engineering plastic to support and protect the endotracheal tube 3, and the outer sleeve 72 can be made of silicone to buffer the occlusion of the incisors.

[0048] Example 2

[0049] Embodiment 2 of this utility model, based on Embodiment 1, further defines the positioning member 4, such as... Figure 4 As shown, the neuromonitoring endotracheal tube protection device also includes a positioning element 4. The positioning element 4 is disposed between the cannula body 21 and the endotracheal tube interface 5 to fix the cannula body 21 onto the endotracheal tube interface 5. The inner ring of the positioning element 4 is fitted onto the endotracheal tube interface 5, so that the part of the cannula body 21 away from the human body is fixedly fitted onto the endotracheal tube interface 5. Thus, both ends of the cannula body 21 are fixed to the connecting base 1 and the endotracheal tube interface 5, respectively. When an external force is applied in the direction of the endotracheal tube 3, the cannula body 21 first bears the force and then transmits the force to the connecting base 1 and the endotracheal tube interface 5, rather than acting directly on the endotracheal tube 3. Through the fixing effect of the positioning element 4, the risk of damage to the endotracheal tube 3 caused by external force during the operation can be reduced, and the stability of the entire device is improved.

[0050] A preferred embodiment of this utility model is as follows: Figure 4 As shown, the endotracheal tube interface 5 is provided with an interface protrusion ring, and the inner ring of the positioning member 4 is sleeved on the interface protrusion ring. Through the interface protrusion ring, the inner ring of the positioning member 4 clamps the endotracheal tube interface 5 more stably.

[0051] A preferred embodiment of this utility model is as follows: Figure 4 As shown, the positioning component 4 includes two fan-shaped clamping pieces 41, both of which are disposed between the endotracheal tube interface 5 and the cannula body 21. A gap is provided between the two fan-shaped clamping pieces for the endotracheal tube interface 5 to enter. Specifically, the side of the fan-shaped clamping piece 41 that abuts against the endotracheal tube interface 5 is an arc-shaped structure. This arc-shaped structure surrounds the endotracheal tube interface 5. The endotracheal tube interface 5 is clamped by the two arc-shaped structures surrounding it. The clamping in two directions ensures the stability of the clamping. The gap between the two fan-shaped clamping pieces 41 can accommodate endotracheal tube interfaces 5 of different sizes, ensuring the versatility and flexibility of the device. The part of the fan-shaped clamping piece 41 that abuts against the endotracheal tube interface 5 should be elastic.

[0052] A preferred embodiment of this utility model is as follows: Figure 5 As shown, the fan-shaped clamping piece 41 includes a connecting rod 411, a rigid clamping piece 412, and a flexible clamping piece 413. The connecting rod 411 is disposed on the sleeve body 21, the rigid clamping piece 412 is disposed on the connecting rod 411, one end of the flexible clamping piece 413 is disposed on the rigid clamping piece 412, and the other end of the flexible clamping piece 413 is used to clamp the endotracheal tube interface 5. The rigid clamping piece 412 is used to provide a stable support structure to ensure the overall stability of the fan-shaped clamping piece 41. The flexible clamping piece 413 has deformation capability, can buffer stress, and can adapt to endotracheal tube interfaces 5 of different diameters, enhancing overall flexibility. For example, the connecting rod 411 and the rigid clamping piece 412 can both be made of medical PVC material, and the flexible clamping piece 413 can be made of silicone or sponge material. One end of the flexible clamping piece 413 can be disposed on the rigid clamping piece 412 by adhesive bonding.

[0053] A preferred embodiment of this utility model is as follows: Figure 5 As shown, the fan-shaped clamping piece 41 also includes a support rib 414, which is connected between the rigid clamping piece 412 and the flexible clamping piece 413 to prevent the flexible clamping piece 413 from deforming. Specifically, the support rib 414 can be partially or completely embedded between the rigid clamping piece 412 and the flexible clamping piece 413 to increase the structural strength and maintain the structural stability of the flexible clamping piece 413. For example, the support rib 414 can be made of rubber and can be rod-shaped.

[0054] A preferred embodiment of this utility model is as follows: Figure 6 As shown, the connecting rod 411 has a first slot 4111 and a second slot 4112. The first slot 4111 is used for inserting the sleeve body 21, and the second slot 4112 is used for inserting the rigid clamping piece 412. The slot design makes the installation process simpler, and the sleeve body 21 and the rigid clamping piece 412 can be quickly inserted into place, improving assembly efficiency. At the same time, disassembly is also convenient. As an improvement, in order to make the fit between the second slot 4112 and the rigid clamping piece 412 more secure, the two adopt an interference fit. Similarly, the first slot 4111 and the sleeve body 21 are also an interference fit.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
