Description

Technical Field

[0001] This utility model relates to the field of endotracheal intubation technology, and in particular to a detachable and replaceable clamp-type neuromonitoring endotracheal intubation tube. Background Technology

[0002] Neuromonitoring endotracheal tubes are a special type of endotracheal tube used in the medical field. They are mainly used during surgery or in situations where continuous monitoring of a patient's breathing and laryngeal muscle nerve activity is required. Due to their special design, clip-on neuromonitoring endotracheal tubes can be connected to suitable neuromonitoring devices to monitor the patient's neurological activity.

[0003] However, most neurological monitoring endotracheal tubes do not have good disassembly and replacement functions, making it inconvenient to replace the connectors. This makes it difficult to connect different sized plugs, wasting valuable surgical time, and has certain defects in use. This reduces the practicality of the tube and has an adverse impact on the user experience of doctors and patients during surgery.

[0004] Therefore, those skilled in the art have provided a detachable and replaceable clamp-on endotracheal tube for neurological monitoring to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable and replaceable clamp-on endotracheal tube for neurological monitoring. The tube moves upward by rotating a knob connected to the lower threaded portion of the outer wall of the threaded tube, which in turn lifts the first tray and the locking hooks fixedly connected to both sides of its upper end. At this time, the two spring-loaded telescopic rods between the first and second trays are compressed and contracted. The locking hooks and their internal slots, which were originally engaged due to the tension of the spring-loaded telescopic rods on the upper end of the second tray, disengage from the locking blocks fixed to the second connecting sleeve. The second connecting sleeve, now unengaged, can then be removed and replaced. When replacing the second connecting sleeve, rotating the knob downwards causes the first tray to engage with the spring-loaded telescopic rods, restoring their tension. The locking blocks and the internal slots of the locking hooks then engage again due to tension, thus completing the entire disassembly and replacement process. This improves the practicality of the tube and optimizes the experience for both doctors and patients using the tube during surgery.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and replaceable clamp-type neuromonitoring endotracheal tube, comprising a replacement mechanism and a protective mechanism. The lower end of the replacement mechanism is provided with the protective mechanism. The replacement mechanism includes a threaded tube, with a first connecting sleeve threadedly connected to the lower part of the outer wall of the threaded tube, a knob threadedly connected to the middle part of the outer wall of the threaded tube, a first tray fitted on the middle part of the outer wall of the threaded tube, spring telescopic rods provided on both sides of the upper end face of the first tray, and snap-fit ​​hooks fixedly connected to the other two sides of the upper end face of the first tray. The upper ends of the two snap-fit ​​hooks are provided with snap-fit ​​grooves. The upper part of the outer wall of the threaded tube is fixedly connected with a second tray, and through grooves are provided on both sides of the interior of the second tray. The upper end of the threaded tube is fitted with a second connecting sleeve, and snap-fit ​​blocks are fixedly connected to both sides of the lower part of the outer wall of the second connecting sleeve. A sealing ring is provided on the upper end of the interior of the second connecting sleeve, and a flexible tube is fixedly connected to the lower part of the interior of the first connecting sleeve.

[0007] Through the above technical solution, the cannula moves upward by rotating the knob connected to the lower threaded part of the outer wall of the threaded tube, thereby pushing the first tray and the locking hooks fixedly connected to both sides of its upper end face upward. At this time, the two spring telescopic rods set between the first and second trays are squeezed and contracted. The locking hooks and the internal slots on the upper end face of the second tray, which were originally locked due to the tension of the spring telescopic rods, disengage from the locking blocks fixedly connected to the second connecting sleeve. At this time, the second connecting sleeve, which is in a unlocked state, can be taken out and replaced. When replacing the new second connecting sleeve, the knob is rotated downward, the first tray contacts the compression of the spring telescopic rods, the tension of the spring telescopic rods is restored, and the locking blocks and the internal slots of the locking hooks are locked again due to the tension, thus completing the entire disassembly and replacement process, improving the practicality of the cannula and optimizing the experience of doctors and patients using the cannula during surgery.

[0008] Furthermore, the protective mechanism includes an airbag, an inflation tube is provided on one side of the upper part of the outer wall of the airbag, an air nozzle is provided at one end of the inflation tube, an electrode connection is provided on one side of the middle part of the outer wall of the airbag, and an electrode head is provided at one end of the electrode connection.

[0009] With the above technical solution, the entire cannula is wrapped by an air balloon. After the air balloon is filled with gas through the air nozzle and inflation tube, the entire cannula is protected by gas, which prevents the cannula from breaking due to movement during surgery and thus avoids damage to the patient's internal tissues. This improves the safety of cannula insertion and optimizes the user experience for both doctors and patients.

[0010] Furthermore, a knob is provided above the first connecting sleeve, and the threaded tube portion between the knob and the first connecting sleeve has no thread distribution;

[0011] Through the above technical solution, this setting enables the knob to rotate within a specified range without exceeding it, and the first connecting sleeve to accurately connect with the thread without slipping.

[0012] Furthermore, the two hook rods penetrate the through slots opened on both sides of the inside of the second tray and form a snap-fit ​​connection with the snap blocks fixedly connected to the lower sides of the outer wall of the second connecting sleeve;

[0013] Through the above technical solution, this setting enables the snap-fit ​​hook to be firmly engaged with the snap-fit ​​block without shifting.

[0014] Furthermore, the upper ends of the two spring telescopic rods are fixedly connected to the second tray, and the threaded tube portion between the first tray and the second tray has a threaded distribution;

[0015] Through the above technical solution, this setting enables the two spring telescopic rods to be firmly fixed between the first and second trays and to undertake the work of supporting the telescopic movement between the trays.

[0016] Furthermore, the flexible tube is connected to the threaded tube, and the diameter of the threaded tube is the same as the diameter of the flexible tube;

[0017] Through the above technical solution, this setup enables the gas introduced into the threaded tube to enter the flexible tube efficiently and ultimately reach the patient's body.

[0018] Furthermore, a flexible tube is fixedly connected to the center of the airbag, and the aperture of the airbag is larger than the aperture of the first connecting sleeve.

[0019] Through the above technical solution, this design enables the airbag to provide all-round protection for the hose.

[0020] Furthermore, the inflation tube penetrates the outer wall of the airbag and communicates with the internal cavity of the airbag;

[0021] The above technical solution enables gas to enter the airbag efficiently through the nozzle and inflation tube.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a detachable and replaceable clamp-type endotracheal tube for neurological monitoring. The tube moves upward by rotating a knob connected to the lower threaded part of the outer wall of the threaded tube, which in turn pushes the first tray and the locking hooks fixedly connected to both sides of its upper end face upward. At this time, the two spring telescopic rods set between the first and second trays are squeezed and contracted. The locking hooks and the internal slots of the second tray, which were originally locked due to the tension of the spring telescopic rods, disengage from the locking blocks fixedly connected to the second connecting sleeve. At this time, the second connecting sleeve, which is in a unlocked state, can be taken out and replaced. When replacing the new second connecting sleeve, the knob is rotated downward, the first tray contacts the compression of the spring telescopic rods, the tension of the spring telescopic rods is restored, and the locking blocks and the internal slots of the locking hooks are locked again due to the tension, thus completing the entire disassembly and replacement process, improving the practicality of the tube and optimizing the experience of medical staff and patients using the tube during surgery.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0034] A detachable and replaceable clamp-on endotracheal tube for neurological monitoring includes a replacement mechanism 1 and a protective mechanism 2. The protective mechanism 2 is provided at the lower end of the replacement mechanism 1. The replacement mechanism 1 includes a threaded tube 101. A first connecting sleeve 102 is threadedly connected to the lower part of the outer wall of the threaded tube 101. A knob 103 is threadedly connected to the middle part of the outer wall of the threaded tube 101. A first tray 104 is sleeved on the middle part of the outer wall of the threaded tube 101. Spring telescopic rods 105 are provided on both sides of the upper end face of the first tray 104. The other side of the upper end face of the first tray 104... Both sides are fixedly connected with snap-fit ​​hooks 106. The upper ends of the two snap-fit ​​hooks 106 have snap-fit ​​grooves 107. The upper part of the outer wall of the threaded tube 101 is fixedly connected with a second tray 108. Both sides of the inner wall of the second tray 108 have through grooves 109. The upper end of the threaded tube 101 is fitted with a second connecting sleeve 111. Both sides of the lower part of the outer wall of the second connecting sleeve 111 are fixedly connected with snap-fit ​​blocks 110. The upper end of the inner wall of the second connecting sleeve 111 is provided with a sealing ring 112. The lower part of the inner wall of the first connecting sleeve 102 is fixedly connected with... The flexible tube 113, through the knob 103 threaded to the lower part of the outer wall of the threaded tube 101, rotates upward, thereby pushing the first tray 104 and the snap-fit ​​hooks 106 fixedly connected to both sides of its upper end face upward. At this time, the two spring telescopic rods 105 set between the first tray 104 and the second tray 108 are squeezed and contracted. The snap-fit ​​hooks 106 and the internal slots 107 of the second tray 108, which were originally locked due to the tension of the spring telescopic rods 105, are fixedly connected to the snap-fit ​​blocks 111 on the second connecting sleeve 111. When the two parts are disengaged, the second connecting sleeve 111, which is in a disengaged state on the upper end of the threaded tube 101, can be removed and replaced. When replacing the new second connecting sleeve 111, the knob 103 is rotated downwards, the first tray 104 releases the pressure on the spring telescopic rod 105, the tension of the spring telescopic rod 105 is restored, and the locking block 110 and the locking groove 107 inside the locking hook rod 106 are locked again due to tension, thus completing the entire disassembly and replacement process, improving the practicality of the intubation and optimizing the intubation experience for doctors and patients during surgery.

[0035] Reference Figure 3-5 The protective mechanism 2 includes an airbag 201. An inflation tube 202 is provided on one side of the upper outer wall of the airbag 201. An air nozzle 203 is provided at one end of the inflation tube 202. An electrode connection 204 is provided on one side of the middle outer wall of the airbag 201. An electrode head 205 is provided at one end of the electrode connection 204. The intubation tube is wrapped around the entire flexible tube 113 by the airbag 201. After the airbag 201 is filled with gas through the air nozzle 203 and the inflation tube 202 into the internal chamber until it is full, the entire flexible tube 113 is under the protection of the gas. This prevents the flexible tube 113 from being broken due to the movement of the intubation tube during the operation, which would damage the patient's internal tissues. This improves the safety of the intubation and optimizes the user experience for both doctors and patients.

[0036] A knob 103 is provided above the first connecting sleeve 102. The threaded tube 101 between the knob 103 and the first connecting sleeve 102 has no thread distribution. This arrangement allows the knob 103 to rotate within a specified range without exceeding it, and the first connecting sleeve 102 to make accurate threaded connections without slipping.

[0037] Two snap-fit ​​hooks 106 pass through the through slots 109 opened on both sides of the inside of the second tray 108 and form a snap-fit ​​connection with the snap-fit ​​blocks 110 fixedly connected to the lower sides of the outer wall of the second connecting sleeve 111. This arrangement allows the snap-fit ​​hooks 106 to be firmly snap-fitted to the snap-fit ​​blocks 110 without shifting.

[0038] The upper ends of the two spring telescopic rods 105 are fixedly connected to the second tray 108. The threaded tube 101 between the first tray 104 and the second tray 108 has threads. This arrangement allows the two spring telescopic rods 105 to be firmly fixed between the first tray 104 and the second tray 108 and to support the telescopic work between the trays.

[0039] The flexible tube 113 is connected to the threaded tube 101, and the diameter of the threaded tube 101 is the same as the diameter of the flexible tube 113. This arrangement allows the gas introduced into the threaded tube 101 to enter the flexible tube 113 efficiently and finally enter the patient's body.

[0040] A flexible tube 113 is fixedly connected to the center of the airbag 201. The diameter of the airbag 201 is larger than the diameter of the first connecting sleeve 102. This arrangement enables the airbag 201 to provide all-round protection for the flexible tube 113.

[0041] The inflation tube 202 penetrates the outer wall of the airbag 201 and communicates with the internal cavity of the airbag 201. This arrangement allows gas to enter the airbag 201 efficiently through the air nozzle 203 and the inflation tube 202.

[0042] Working principle: The insertion tube moves upward by rotating the knob 103, which is threaded to the lower part of the outer wall of the threaded tube 101, thereby pushing the first tray 104 and the locking hooks 106 fixedly connected to both sides of its upper end face upward. At this time, the two spring telescopic rods 105 set between the first tray 104 and the second tray 108 are squeezed and contracted. The locking hooks 106 and the internal locking grooves 107 that were originally locked on the upper end face of the second tray 108 due to the tension of the spring telescopic rods 105 are disengaged from the locking blocks 110 fixedly connected to the second connecting sleeve 111. At this time, the second connecting sleeve, which is sleeved on the upper end of the threaded tube 101, can be released from the locking state. When replacing the second connecting sleeve 111, the knob 103 is rotated downwards, the first tray 104 releases the pressure on the spring telescopic rod 105, the tension of the spring telescopic rod 105 is restored, and the locking block 110 and the locking groove 107 inside the locking hook rod 106 are locked again due to tension. The intubation tube is wrapped around the entire flexible tube 113 by the air bag 201. After the air bag 201 is filled with gas through the air nozzle 203 and the inflation tube 202 into the internal chamber until it is full, the entire flexible tube 113 is under the protection of gas, which avoids the movement of the intubation tube during the operation, which may cause the flexible tube 113 to break and thus damage the patient's internal tissues.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
