Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a clinical anesthesia intubation auxiliary device. Background Art

[0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. The current common clinical anesthesia intubation requires the doctor to support the intubation during use, resulting in limited hand operation (i.e. holding the intubation with one hand and operating the instrument with the other hand), which reduces the doctor's work efficiency.

[0003] After searching, the Chinese patent announcement number is CN114870181A, which discloses a clinical anesthesia intubation auxiliary device. In this patent, the wrapping belt is wrapped around the patient's neck under the action of the sub-Velcro and the main Velcro, and the L-shaped fitting rod fits with the patient to fix the position of the support rod. Under the action of the spring elastic potential energy, the cannula is fixed between the upper arc-shaped slot and the lower arc-shaped slot. The plug of the cannula is inserted into the patient's trachea position to complete the anesthesia intubation of the patient. By fixing the cannula, the doctor does not need to support the cannula, which is convenient for the doctor to treat the patient and improves the doctor's work efficiency. At the same time, the butterfly bolt is rotated inside the threaded hole to apply a force to the support rod to make the T-plate slide on the inner wall of the T-shaped slot. The butterfly bolt is rotated to make the butterfly bolt press against the inner wall of the T-shaped slot, thereby fixing the position of the T-plate, which is conducive to adjusting the position of the support rod and improving the use effect of the device.

[0004] However, when the above device is used, firstly, the length of the wrapping belt is fixed and the positions of the mother Velcro and the child Velcro are fixed, so that when used for patients with different neck thicknesses, the wrapping belt may be too tight or too loose. Secondly, the cannula to be used is placed between the upper arc slot and the lower arc slot by the elastic force of the spring to fix the cannula. However, this method requires that the shape of the outer surface of the cannula matches the shape of the upper arc slot and the lower arc slot after combination, and the elastic force of the spring should not be too large, otherwise the cannula will be squeezed. Finally, the position of the support rod is changed by using a butterfly bolt, but this method cannot adjust the height of the support rod, so that when different patients use it, the cannula cannot be aligned with the patient's use position, causing use troubles. Summary of the invention

[0005] The present invention proposes a clinical anesthesia intubation auxiliary device, which has the advantages of adopting an adjustable fixing component to meet the use of patients with different neck thicknesses, effectively fixing the intubation to avoid the intubation being fixed too tightly or too loosely to affect the overall adjustment and use, and adopting an adjustable structure so that the intubation can be directly facing the patient's trachea for easy use by different patients. It solves the problem in the related technology that the length of the tightening belt is fixed, which makes it easy to loosen or tighten the patient when used for patients with thin or thick necks, making it impossible to quickly adapt to different patients, the intubation is fixed too tightly or too loosely, making it difficult or easy to move the intubation, causing the intubation to be unstable and affecting the overall use, and the intubation position cannot be adjusted, resulting in the intubation after being fixed not being able to face different patients.

[0008] Preferably, the second Velcro is arranged on the rear side of the outer surface of the fixed block, the right side of the first Velcro and the left side of the second Velcro are adhered to each other, and the tightening belt is composed of multiple elastic belts and composite belts that are evenly and fixedly connected, the composite belt is constructed of synthetic plastic material, and the elastic belt is constructed of elastic material. Therefore, when in use, the first Velcro and the second Velcro can be used to wrap the tightening belt around the outer surface of the patient's fixed part, and the tightening belt composed of the elastic belt and the composite belt, and the stretchable characteristics of the elastic belt, can be used to facilitate slight rotation and adjustment when used by the patient, so as to avoid wrapping the patient's fixed part too tightly and affecting the patient's normal medical examination.

[0009] Preferably, the shape of the cross-section of the outer surface of the polygonal block matches the shape of the cross-section of the inner cavity of the polygonal hole, and the depth of the inner cavity of the polygonal hole is less than the height of the cylinder. Therefore, when in use, the cylinder is pressed to move the polygonal block downward and separate from the inner cavity of the polygonal hole. At this time, the torsion shaft can rotate in the inner cavity of the fixed block, and then the tightening belt can be stretched to adjust the length of the tightening belt so that the tightening belt can meet the needs of different patients. After the tightening belt is adjusted, the cylinder is released. Under the elastic force of the first spring, the polygonal block and the cylinder automatically move upward, so that the polygonal block extends into the inner cavity of the polygonal hole, thereby fixing the torsion shaft and preventing the torsion shaft from rotating arbitrarily and causing the length of the tightening belt to change during use.

[0010] Preferably, the first slide groove and the second slide groove inner cavity are both provided with limit grooves on the upper and lower sides, and the limit grooves both penetrate the first slide groove and the second slide groove inner cavity, and limit blocks are fixedly installed on the right sides on the upper and lower sides of the bottom inner plate and the left sides on the upper and lower sides of the top inner plate, and the cross-sectional shape of the bottom inner plate after the right limit blocks on the upper and lower sides are combined matches the shape of the cross-sectional shape of the first slide groove and the inner cavity of the limit groove, and the cross-sectional shape of the top inner plate after the left limit blocks on the upper and lower sides are combined matches the shape of the second slide groove and the inner cavity of the limit groove, so that when in use, the limit grooves on the upper and lower sides of the inner cavity of the first slide groove and the second slide groove and the limit blocks fixedly installed on the right sides on the upper and lower sides of the bottom inner plate and the left sides on the upper and lower sides of the top inner plate are utilized, so that the bottom inner plate and the top inner plate will not slide out of the inner cavity of the bottom outer plate and the top outer plate.

[0011] Preferably, the first socket and the second socket are evenly arranged on the front sides of the bottom inner plate and the top inner plate, and the shapes of the cross-sections of the inner cavities of the first socket and the second socket respectively match the shapes of the cross-sections of the first plug rod and the second plug rod, so that when in use, the shapes of the cross-sections of the inner cavities of the first socket and the second socket respectively match the shapes of the cross-sections of the first plug rod and the second plug rod, so that the first plug rod and the second plug rod can be inserted into the inner cavities of the first socket and the second socket, thereby fixing the positions of the bottom outer plate and the bottom inner plate when in use and fixing the positions of the top outer plate and the top inner plate when in use, avoiding automatic displacement during use, resulting in unstable fixed position of the insertion tube.

[0012] Preferably, the middle right portion of the front side of the bottom outer panel and the middle left portion of the front side of the top outer panel are both provided with through holes matching the outer surface shapes of the first plug rod and the second plug rod, the through hole, the first plug hole and the middle portions of the first plug rod are in the same horizontal plane, and the through hole, the second plug hole and the middle portions of the second plug rod are all in the same horizontal plane, so that when in use, the first plug rod is inserted into the inner cavity of the first plug hole through the through hole to fix the position of the bottom outer panel and the bottom inner panel when in use, and at the same time, the second plug rod is inserted into the inner cavity of the second plug hole through the through hole to fix the position of the top outer panel and the top inner panel when in use.

[0013] Preferably, the stretchable length of the second spring is greater than the inner cavity depth of the first hole and smaller than the distance between the bottom of the inner cavity of the first hole and the outer surface of the front side of the bottom outer plate, and the stretchable length of the third spring is greater than the inner cavity depth of the second hole and smaller than the distance between the bottom of the inner cavity of the second hole and the outer surface of the front side of the top outer plate. Therefore, when in use, the first plug-in rod and the second plug-in rod can be moved out of the inner cavity of the first hole and the second hole by stretching the second spring and the third spring, thereby facilitating the bottom inner plate and the top inner plate to move in the inner cavities of the bottom outer plate and the top outer plate respectively.

[0014] Preferably, the stretchable length of the telescopic rod is greater than the distance between the first plug rod and the second plug rod after being flipped and stretched to the maximum length, and the telescopic rod is connected to the second plug rod and the front side of the outer surface of the first plug rod through circular rings on the left and right sides respectively, so that when in use, the stretchable length of the telescopic rod is utilized to facilitate the connection between the first plug rod and the second plug rod, and the first plug rod and the second plug rod are rotated to be connected to the left and right sides of the telescopic rod, so that the use of the first plug rod and the second plug rod will not affect the normal stretching and contraction of the telescopic rod.

[0015] Preferably, the rubber pad is constructed of a synthetic rubber material, and there is a gap between the pressure plate and the rear side of the support block. When in use, the rubber material of the rubber pad and the elastic force between the pressure plate and the support block through the torsion shaft are utilized to fix the cannula during use. The rubber pad is utilized to avoid severe squeezing of the cannula and at the same time increase the friction force when the cannula moves, thereby preventing the cannula from easily moving out of the gap between the pressure plate and the support block, thereby improving the stability of the cannula during use.

[0016] The working principle and beneficial effects of the present invention are:

[0017] 1. The clinical anesthesia intubation auxiliary device cooperates with the torsion shaft structure and the tightening belt structure. When working, the cylinder is pressed down to separate the polygonal block from the polygonal hole, which is convenient for the rotation of the torsion shaft, and then the length of the tightening belt is adjusted. The tightening belt is composed of an elastic belt and a composite belt. After the second Velcro is pulled to wrap the tightening belt around the outer surface of the patient's fixed part, it is fixed with the first Velcro. The elastic belt in the tightening belt allows the tightening belt to rotate within a certain range after being fixed, avoiding over-tight or over-loose winding, so as to achieve the effect of using an adjustable fixing component to meet the use of patients with different neck thicknesses.

[0018] 2. The clinical anesthesia intubation auxiliary device uses a pressure plate structure and a support block structure in coordination. When working, the pressure plate and the support block are used to fix the cannula to be used, and the rubber pad is used to prevent the cannula from being fixed too tightly. At the same time, the rubber material of the rubber pad is used to prevent the cannula from being easily moved when fixed, so as to achieve the effect of effectively fixing the cannula and preventing the cannula from being fixed too tightly or too loosely to affect the overall adjustment and use.

[0019] 3. The clinical anesthesia intubation auxiliary device, through the coordinated use of the first plug rod structure and the second spring structure, can separate the first plug rod and the second plug rod from the first socket and the second socket by moving the telescopic rod forward during operation, so that the position between the top outer plate and the top inner plate and the bottom outer plate and the bottom inner plate changes. In conjunction with the rotatable fixed plate, the angle between the bottom outer plate and the top outer plate after the adjustment of the position can be adjusted until the support block is facing the patient's intubation position, thereby achieving the effect of using an adjustable structure so that the intubation can be facing the patient's trachea for easy use by different patients.

A second slide groove 22 is provided on the left side of the top outer plate 21, and the inner cavity of the second slide groove 22 is slidably installed with the top inner plate 23. A plurality of second plug holes 24 are provided on the front side of the top inner plate 23, and the stretchable length of the second spring 14 is greater than the inner cavity depth of the first plug hole 13 The third spring 25 can be stretched to a length greater than the inner cavity depth of the second hole 24 and less than the distance between the inner cavity bottom of the second hole 24 and the outer surface of the front side of the top outer plate 21. Thus, when in use, the first plug rod 16 and the second plug rod 27 can be moved out of the inner cavities of the first hole 13 and the second hole 24 by stretching the second spring 14 and the third spring 25, thereby facilitating the bottom inner plate 12 and the top inner plate 23 to move in the inner cavities of the bottom outer plate 10 and the top outer plate 21 respectively. The first hole 13 and the second hole 24 are evenly arranged on the front sides of the bottom inner plate 12 and the top inner plate 23. The shapes of the inner cavity cross sections of the first hole 13 and the second hole 24 are respectively the same as those of the third spring 25 and the third spring 25. The shapes of the cross sections of the first plug rod 16 and the second plug rod 27 match each other, so that when in use, the shapes of the cross sections of the inner cavities of the first plug hole 13 and the second plug hole 24 are matched with the shapes of the cross sections of the first plug rod 16 and the second plug rod 27, respectively, so as to facilitate the first plug rod 16 and the second plug rod 27 to extend into the inner cavities of the first plug hole 13 and the second plug hole 24, thereby fixing the positions of the bottom outer plate 10 and the bottom inner plate 12 when in use and fixing the positions of the top outer plate 21 and the top inner plate 23 when in use, so as to avoid automatic displacement during use, resulting in unstable fixed position of the insertion tube, a third spring 25 is fixedly installed on the top left side of the front side of the top outer plate 21, a second cross plate 26 is fixedly installed on the front side of the third spring 25, and a third cross plate 26 is fixedly installed on the bottom of the second cross plate 26 The second plug rod 27, the middle part of the right side of the front side of the bottom outer plate 10 and the middle part of the left side of the front side of the top outer plate 21 are both provided with through holes matching the outer surface shapes of the first plug rod 16 and the second plug rod 27, the through hole, the first plug hole 13 and the middle part of the first plug rod 16 are in the same horizontal plane, the through hole, the second plug hole 24 and the middle part of the second plug rod 27 are all in the same horizontal plane, so that when in use, the first plug rod 16 is inserted into the inner cavity of the first plug hole 13 through the through hole to fix the position of the bottom outer plate 10 and the bottom inner plate 12 when in use, and the second plug rod 27 is inserted into the inner cavity of the second plug hole 24 through the through hole to fix the position of the top outer plate 21 and the top inner plate 23 when in use, and the front side of the outer surface of the second plug rod 27 and the first plug rod 16 is rotatably installed with a telescopic rod 28,The stretchable length of the telescopic rod 28 is greater than the distance between the first plug rod 16 and the second plug rod 27 after being turned over and stretched to the maximum length. The telescopic rod 28 is connected to the front side of the outer surface of the second plug rod 27 and the first plug rod 16 through rings on the left and right sides respectively. Therefore, when in use, the stretchable length of the telescopic rod 28 is used to facilitate the connection between the first plug rod 16 and the second plug rod 27. The rotation connection of the first plug rod 16 and the second plug rod 27 with the left and right sides of the telescopic rod 28 is coordinated so that the use of the first plug rod 16 and the second plug rod 27 will not affect the normal stretching and contraction of the telescopic rod 28. The left side of the top inner plate 23 is rotatably mounted with a support block 29 through a universal shaft. A pressing plate 30 is rotatably mounted on the left side of the support block 29 through the torsion shaft 3. A rubber pad 31 is fixedly mounted in the inner cavity of the support block 29 and the pressing plate 30. The rubber pad 31 is made of synthetic rubber material. There is a gap between the pressing plate 30 and the rear side of the support block 29. When in use, the rubber material of the rubber pad 31 and the elastic force between the pressing plate 30 and the support block 29 through the torsion shaft 3 are used to fix the cannula during use. The rubber pad 31 can avoid severe squeezing of the cannula and increase the friction when the cannula moves, thereby preventing the cannula from easily moving out of the gap between the pressing plate 30 and the support block 29, thereby improving the stability of the cannula when in use.

[0033] Working principle: When working, first press the cylinder 8 to make the polygonal block 7 move down and separate from the inner cavity of the polygonal hole 9. At this time, the torsion shaft 3 in the inner cavity of the fixing block 1 can rotate, then stretch the tightening belt 4 to make it wrap around the outer surface of the patient's fixation, and then stretch the second Velcro 5 and fit it with the first Velcro 2 to fix it, and then loosen the cylinder 8 to make the polygonal block 7 move upward under the elastic force of the first spring 6 so that the polygonal block 7 extends into the inner cavity of the polygonal hole 9, so as to fix the torsion shaft 3, avoid the torsion shaft 3 from rotating during use, causing the tightening belt 4 to shrink or stretch, and then affect the stability of the fixing block 1 when it is fixed, so as to achieve the effect of using an adjustable fixing component to meet the use of patients with different neck thicknesses;

[0034] Then, the pull ring in the middle of the telescopic rod 28 is stretched forward to stretch the first plug rod 16 and the second plug rod 27 forward, so that the first plug rod 16 and the second plug rod 27 move forward and separate from the inner cavity of the first plug hole 13 and the second plug hole 24. At this time, the bottom inner plate 12 and the top inner plate 23 can move in the inner cavity of the bottom outer plate 10 and the top outer plate 21. Then, after the bottom inner plate 12 and the top inner plate 23 are moved to the appropriate position in the inner cavity of the bottom outer plate 10 and the top outer plate 21, the pull ring is released, and the telescopic rod 28, the first plug rod 16 and the second plug rod 27 automatically move backward, so that the first plug rod 16 and the second plug rod 27 move into the inner cavity of the first plug hole 13 and the second plug hole 24 on the rear side, thereby fixing the stretched bottom outer plate 1 0 and the bottom inner plate 12 and the stretched top outer plate 21 and the top inner plate 23, and then move the rotating fixed plate 19 forward, and use the thread opened on the outer surface of the round rod fixedly installed on the rear side of the fixed plate 19 to match the inner cavity of the threaded hole on the front side of the circular shaft 18, so that the fixed plate 19 after moving forward is no longer fixed on the circular column 17 and the circular ring plate 20 on the outer surface of the circular shaft 18, and then the bottom outer plate 10 and the bottom inner plate 12 after adjusting the length can rotate with the top outer plate 21 and the top inner plate 23 after adjusting the length, so that the position of the support block 29 is directly opposite to the intubation position of the patient, so as to achieve the effect of using an adjustable structure so that the intubation can be directly opposite to the patient's trachea for easy use by different patients;

[0035] Finally, the pressing plate 30 connected to the support block 29 through the torsion shaft 3 and the rubber pad 31 provided between the inner cavities of the support block 29 and the pressing plate 30 are used. When in use, the pressing plate 30 is flipped upward and the cannula is placed between the inner cavities of the pressing plate 30 and the support block 29. The pressing plate 30 is then released, and the cannula in the inner cavity of the support block 29 is fixed by the pressing plate 30 and the rubber pad 31. The cannula is prevented from being fixed too tightly, and the friction between the rubber pad 31 and the outer surface of the cannula is increased to improve the stability of the cannula when it is fixed. At the same time, a large external force can be used to stretch the fixed cannula back and forth, so as to effectively fix the cannula and avoid the cannula being fixed too tightly or too loosely to affect the overall adjustment and use.

[0036] In summary, compared with general similar devices, this clinical anesthesia intubation auxiliary device has the advantages of using an adjustable fixing component to meet the needs of patients with different neck thicknesses, effectively fixing the intubation to avoid the intubation being fixed too tightly or too loosely affecting the overall adjustment and use, and using an adjustable structure so that the intubation can be directly facing the patient's trachea to facilitate use by different patients.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
