Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an integrated system for anesthetic airway intubation assistance, fixation, and lighting. Background Technology

[0002] Endotracheal intubation is a core medical procedure for establishing an artificial airway and ensuring stable ventilation and oxygenation during surgery. It is widely used in general anesthesia, critical care respiratory support, and emergency treatment of cardiac and respiratory arrest. After the endotracheal tube is inserted, it must be reliably secured. If it is not securely fixed, slight head movements, instrument contact during surgery, body displacement, or patient transport can all cause the tube to shift, dislodge, or deviate from its insertion depth. This can lead to serious adverse events such as insufficient ventilation, carbon dioxide retention, airway mucosal compression and damage, and asphyxiation, directly endangering the patient's life.

[0003] Currently, the clinical methods for fixing endotracheal tubes mainly include three types: medical tape wrapping, elastic fixation straps, and simple tube clamps. However, all of them have certain drawbacks: medical tape is easily soaked by the patient's oral and nasal secretions, sweat, and blood, and its adhesiveness quickly weakens and fails, resulting in poor fixation stability; elastic fixation straps can only restrain the patient's head and tube as a whole, and cannot accurately limit the tube at specific points, so there is still a risk of the tube sliding and deviating; traditional tube clamping structures are mostly rigid clamping and locking structures without adaptive buffering structures, which can easily squeeze the tube, causing tube deformation and narrowing of the ventilation cavity.

[0004] In addition, existing catheter fixation structures generally lack dedicated local lighting for the insertion area. In scenarios such as emergency resuscitation at night, sterile single-sided main light source in the operating room, and bedside catheterization in a dark room, the insertion field of vision is dim and there are blind spots, which greatly increases the difficulty of positioning and fixing the catheter. At the same time, the existing catheter fixation structure and lighting equipment are separate and independent structures. The instruments are scattered and occupy the limited sterile operating space of the patient's head and face, which can easily lead to mutual interference and wire entanglement during the operation, resulting in low overall operation efficiency.

[0005] Most existing intubation-assisted fixation devices lack specific neck support and position adjustment structures, leaving the patient's neck suspended during intubation, the laryngeal airway unable to open fully, and the glottis insufficiently exposed, increasing the difficulty of intubating difficult airways. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an integrated system for endotracheal intubation assistance, fixation, and illumination, as well as a method of use. This system solves many problems existing in current endotracheal intubation fixation methods, achieving integrated clinical functions such as neck support, multi-dimensional angle adjustment, elastic adaptive clamping, local soft lighting, and rapid assembly and disassembly.

[0016] Preferably, the opening and closing clamping head includes a fixed clamping half ring and a movable clamping half ring. One end of the fixed clamping half ring and one end of the movable clamping half ring are hinged by an opening and closing pin. A fastening component is provided between the end faces of the opening and closing ends of the fixed clamping half ring and the movable clamping half ring.

[0017] Two elastic plates arranged symmetrically on the inner walls of both the fixed clamping half-ring and the movable clamping half-ring are fixedly installed. The free end of each elastic plate is inclined toward the axis of the fixed clamping half-ring and the movable clamping half-ring, respectively. An arc-shaped clamping plate is fixedly installed at the free end of each elastic plate.

[0018] Preferably, the lighting assembly includes an arc-shaped groove formed on the bottom end face of the fixed clamping half-ring and the movable clamping half-ring, and an LED light panel is fixedly installed in the arc-shaped groove.

Two guide rods are fixedly installed on the side of the base facing the neck support base plate, and the two guide rods are coaxially corresponding to the positions of the two guide holes and are respectively inserted into the two guide holes.

[0020] A neck support screw hole is provided in the middle of the side of the neck support base plate facing the base. A through hole is provided between the front and rear sides of the base, and a neck support adjustment rod is rotatably installed in the through hole. The front end of the neck support adjustment rod extends out of the through hole and extends to the front side of the base. A threaded section is provided on the outer side of the extended end of the front end of the neck support adjustment rod. The threaded section extends into the neck support screw hole and forms a threaded engagement with it.

[0021] The present invention also provides a method for using an integrated system for anesthetic airway intubation assistance, fixation, and illumination, comprising the following steps:

[0022] a. Equipment clamping and positioning: Pull the two U-shaped buckles outward to compress the corresponding buckle springs. After placing the base on the operating table, release the two U-shaped buckles to engage on both sides of the operating table, and then tighten the two buckle fixing bolts to complete the fixation. Place the patient's head on the headrest, rotate the neck support adjustment rod to drive the neck support base plate to slide back and forth along the guide rod, adjust the position of the neck support to support the neck and open the airway.

[0023] b. Multi-angle pre-adjustment of the clamping head: Loosen the displacement positioning bolt, slide the two displacement sliders synchronously along the two displacement grooves to adjust the front and rear position of the semi-circular C-shaped guide rail, and achieve positioning by tightening the displacement positioning bolt; Loosen the two angle positioning nuts, flip the semi-circular C-shaped guide rail along the two semi-circular angle grooves to the appropriate tilt angle, and then tighten the two angle positioning nuts to lock the positioning; Loosen the clamping positioning bolt, slide the arc-shaped slider to drive the opening and closing clamping head to align with the patient's mouth, and then tighten the clamping positioning bolt to lock the positioning.

[0024] c. Intubation lighting and clamping fixation: Turn on the LED light panel to provide supplemental lighting to the intubation area; manually open the fastening assembly, then pry open the movable clamping half ring, place the endotracheal tube between the two clamping half rings and close the clamping head, the fastening assembly locks the two clamping half rings; the endotracheal tube squeezes the arc-shaped clamping plate to deform the elastic sheet, and the elastic force adaptively clamps and fixes the endotracheal tube.

[0025] d. Intraoperative maintenance and postoperative disassembly: During the operation, the semi-circular C-shaped guide rail and arc-shaped slider can be finely adjusted to compensate for the slight movement of the patient's head; after the operation is completed, manually open the fastening assembly to unlock the clamping head and take out the catheter, loosen the two buckle fixing bolts, and pull the two U-shaped buckles outward to remove the entire device for disinfection and storage.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. By setting elastic sliding U-shaped buckles on both sides of the base, it can be adapted to the assembly of operating tables and emergency beds of different sizes. It relies on the spring force to adaptively lock and tighten, and the buckle fixing bolts can achieve mechanical locking and fixation. It is quick to assemble and disassemble, securely fixed, and has no slippage or loosening.

[0028] 2. By setting a semi-circular C-shaped guide rail on the top of the base that can slide back and forth and tilt, and rotate the pitch angle, and in conjunction with the arc sliding of the arc slider, the front and back position, pitch angle and arc position of the opening and closing clamping head can be adjusted steplessly and precisely at multiple angles, so that it can be accurately aligned with the patient's mouth and nose and adapt to the intubation angle of patients of different body types.

[0029] 3. By setting up an openable self-locking clamping head structure, combined with a detachable and replaceable inclined elastic plate and arc-shaped clamping plate structure, it can adaptively and elastically clamp and fix the endotracheal tube according to its outer diameter. The clamping force is uniform and gentle, eliminating rigid compression that could cause tube deformation or damage. At the same time, the elastic plate structure can buffer minor external force interference during the operation, effectively preventing tube displacement or dislodgement. The elastic plate assembly adopts a detachable plug-in assembly structure, which is convenient for disassembly and assembly, and easy for disinfection and replacement, avoiding elastic fatigue failure of the elastic plate after long-term use.

[0030] 4. By setting an LED lighting component at the bottom of the clamping head, the light is precisely directed towards the intubation area of ​​the patient's mouth and nose, eliminating the need for additional handheld light sources or medical headlamps. This completely solves the problems of separate instruments occupying sterile operating space and wires interfering with surgery, accurately supplementing the blind spots of intubation and significantly improving the accuracy of intubation and fixation operations in low-light environments.

[0031] 5. By setting an adjustable neck support component, the neck support position can be precisely adjusted, actively raising the patient's neck, fully opening the laryngeal airway, assisting in exposing the glottis and the intubation field of vision, effectively reducing the difficulty of intubation of difficult airways, and improving the success rate and efficiency of intubation.

Detailed Implementation

[0046] The specific structure, assembly and connection method, working principle, and usage process of the present invention will be described in complete and clear detail below with reference to the accompanying drawings and specific embodiments. All embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0047] As attached Figures 1-12 As shown, the present invention is an integrated system for anesthetic airway intubation auxiliary fixation and lighting, including a base 1 as the main carrier, a flexible headrest 101 fixedly installed at the center of the top surface of the base 1 for supporting the back of the patient's head; and buckle components 2 symmetrically slidably arranged at the left and right ends of the bottom surface of the base 1, so that the base 1 can be quickly assembled onto the operating table through the two sets of buckle components 2.

[0048] Each set of buckle assembly 2 includes a buckle groove 21, a buckle slider 22, a U-shaped buckle 23, and a buckle spring 24. Two buckle grooves 21 are symmetrically opened at the left and right ends of the bottom surface of the base 1. A buckle slider 22 is slidably installed in each buckle groove 21. A U-shaped buckle 23 is fixedly installed on the bottom surface of each buckle slider 22 by bolts. The openings of the two U-shaped buckles 23 are arranged opposite each other facing the middle of the base 1. A handle is fixedly installed on the side of the U-shaped buckle 23 away from the middle of the base 1. A buckle spring 24 is fixedly installed on the side of the buckle slider 22 away from the middle of the base 1. The other end of the buckle spring 24 is fixedly connected to the side wall of the buckle groove 21 away from the middle of the base 1.

[0049] When the two snap-fit ​​springs 24 are in their normally compressed state, the two snap-fit ​​sliders 22 are both located at the end of the snap-fit ​​groove 21 near the middle of the base 1. During installation, pull the two handles outwards at the same time to move the two U-shaped snaps 23 away from each other. The two snap-fit ​​sliders 22 move synchronously and compress the two snap-fit ​​springs 24. Then, after the base 1 is placed in the corresponding position on the operating table, release the two handles. The elasticity of the two snap-fit ​​springs 24 is released, which moves the two snap-fit ​​sliders 22 and the U-shaped snaps 23 towards the middle of the base 1. The two U-shaped snaps 23 engage on both sides of the operating table, thereby achieving the initial installation and positioning of the base 1, which can be adapted to operating tables of different widths.

[0050] The left and right side walls of the base 1 are respectively provided with snap screw holes 25 between the two snap sliding grooves 21. Snap fixing bolts 26 are installed in the internal threads of the snap screw holes 25. After the base 1 is initially installed and positioned, the two snap fixing bolts 26 are screwed into the two snap sliding grooves 21 until the snap fixing bolts 26 abut against the snap slider 22, thereby locking and positioning the snap slider 22 and achieving the final assembly and fixation of the base 1, ensuring that the base 1 does not loosen or slip during use.

[0051] Two symmetrically arranged displacement grooves 31 are provided on the top surface of the base 1. The displacement grooves 31 extend along the front and back direction of the base 1. The displacement slider 3 is slidably assembled inside the displacement groove 31 and can slide linearly back and forth along the displacement groove 31. A displacement screw hole 32 is vertically opened between the top and bottom surfaces of the displacement slider 3. The displacement positioning bolt 33 is installed in the internal thread of the displacement screw hole 32. When the displacement positioning bolt 33 is tightened, the bottom end of the bolt presses against the bottom of the displacement groove 31, thereby locking and positioning the displacement slider 3.

[0052] A semi-circular C-shaped guide rail 4 is hinged between the tops of the two displacement sliders 3 and mounted on the headrest 101. Both ends of the semi-circular C-shaped guide rail 4 are fixed with hinge blocks 35 by bolts. Two hinge plates 34 are welded and fixed to the top of each displacement slider 3 and arranged symmetrically along its left and right width direction. Each hinge block 35 is rotatably mounted between the two hinge plates 34 on the corresponding side by a pin 36, so that the semi-circular C-shaped guide rail 4 as a whole can be rotated and adjusted in the front and back directions around the pin 36.

[0053] Each displacement slider 3 is fixedly mounted with a semi-circular angle plate 37 on the side away from the middle of the base 1 by bolts. A semi-circular angle groove 38 is opened between the left and right sides of the semi-circular angle plate 37. The center of the semi-circular angle groove 38 is coaxially corresponding to the center of the pin 36. Angle positioning bolts 39 are fixedly installed on the outer surfaces of both ends of the semi-circular C-shaped guide rail 4. The angle positioning bolts 39 pass through the semi-circular angle groove 38 on the corresponding side and are threaded with angle positioning nuts 391.

[0054] Loosening the angle positioning nut 391 allows for free adjustment of the pitch angle of the semicircular C-shaped guide rail 4. During adjustment, the angle positioning bolt 39 moves synchronously along the semicircular angle groove 38 in an arc direction. Tightening the angle positioning nut 391 to make it press against the semicircular angle plate 37 allows for stepless adjustment and locking positioning of the semicircular C-shaped guide rail 4 at any angle. Several anti-slip stripes are provided on the outer side of the semicircular angle plate 37 along the semicircular angle groove 38 to increase the friction between the angle positioning bolt 39 and the semicircular angle plate 37, thereby achieving stable positioning of the semicircular C-shaped guide rail 4.

[0055] The semi-circular C-shaped guide rail 4 is an arc-shaped hollow guide rail structure with a C-shaped cross-section and an opening facing forward. An arc-shaped slider 5 is slidably assembled inside. The arc-shaped slider 5 can slide along the arc-shaped trajectory of the semi-circular C-shaped guide rail 4. A clamping and positioning screw hole 51 is opened through the front and rear sides of the arc-shaped slider 5. A clamping and positioning bolt 52 is installed in the internal thread of the clamping and positioning screw hole 51. Tightening the clamping and positioning bolt 52 makes its end press against the inner wall of the semi-circular C-shaped guide rail 4 to lock and position the arc-shaped slider 5. The front end of the arc-shaped slider 5 extends to the outside of the opening of the semi-circular C-shaped guide rail 4 and is fixedly installed with an opening and closing clamping head 6 by bolts. By adjusting the arc-shaped position of the locking arc-shaped slider 5, the position and angle of the clamping head can be adjusted to accurately align it with the patient's mouth and nose.

[0056] The opening and closing clamping head 6 includes a fixed clamping half ring 61 and a movable clamping half ring 62. The outer wall of the fixed clamping half ring 61 is fixed to the front end face of the arc-shaped slider 5 by bolts. One end of the fixed clamping half ring 61 and one end of the movable clamping half ring 62 are hinged by an opening and closing pin 63, which can realize free opening and closing. A fastening component is provided between the opening and closing end faces of the two to realize self-locking.

[0057] A locking groove 641 is provided on the end face of the opening and closing end of the movable clamping half ring 62. A locking wedge 642 is slidably installed in the locking groove 641. One end of the locking wedge 642 extends to the outside of the locking groove 641 and is integrally formed into an upwardly bent wedge-shaped part. The side of the wedge-shaped part away from the locking groove 641 is a guide slope structure. A locking spring 643 is fixedly installed between the bottom surface of the locking wedge 642 and the bottom surface of the locking groove 641. A locking slot 644 is provided on the end face of the opening and closing end of the fixed clamping half ring 61. The top surface of the locking slot 644 is lower than the top of the wedge-shaped part. A groove that engages with the wedge-shaped part is provided on the top surface of the locking slot 644.

[0058] When the movable clamping half-ring 62 closes towards the fixed clamping half-ring 61, the edge of the top surface of the snap-fit ​​groove 644 presses against the inclined surface of the wedge-shaped part, causing the snap-fit ​​wedge block 642 to be pressed down and compress the snap-fit ​​spring 643. When the wedge-shaped part is fully inserted into the snap-fit ​​groove 644, the snap-fit ​​spring 643 releases its elasticity and pushes the snap-fit ​​wedge block 642 upward, so that the wedge-shaped part is engaged in the groove on the top surface of the snap-fit ​​groove 644, thereby achieving rapid closing and locking of the clamping head.

[0059] A through groove is formed between the snap-fit ​​groove 641 and the outer circumferential surface of the movable clamping half ring 62. One end of the snap-fit ​​wedge 642 located inside the snap-fit ​​groove 641 is fixedly connected by bolts to a pressing block 645 that extends from inside the through groove to the outside of the movable clamping half ring 62. Pressing the pressing block 645 downwards will cause the snap-fit ​​wedge 642 to move downwards, causing the wedge-shaped part to move downwards and disengage from the groove. Then, the movable clamping half ring 62 can be pried open, realizing the quick opening of the clamping head.

[0060] Both the fixed clamping half-ring 61 and the movable clamping half-ring 62 have slots 651 on their inner walls. The tops of the two slots 651 pass through the top end faces of the fixed clamping half-ring 61 and the movable clamping half-ring 62, respectively. Each slot 651 has a plate 652 inserted into it. The top end faces of the fixed clamping half-ring 61 and the movable clamping half-ring 62 have fixed grooves 653 that communicate with the slots 651. Fixed screw holes are formed in the middle of the bottom of the two fixed grooves 653. The top of each plate 652 has an integrally formed horizontal bend 654. The shape of the horizontal bend 654 matches the shape of the fixed groove 653. A fixing bolt 655 is threaded through and installed in the middle of the horizontal bend 654. After the plate 652 is inserted into the slot 651 from top to bottom, the horizontal bend 654 fits into the fixed groove 653. The fixing bolt 655 is screwed into the fixed screw hole to fix the plate 652 and the horizontal bend 654.

[0061] Two sets of symmetrical elastic plates 65 are fixedly arranged on each insert plate 652. The free ends of the elastic plates 65 are inclined towards the axis of the clamping head and are fixedly installed with arc-shaped clamping plates 66. The outer side of the arc-shaped clamping plates 66 is covered with medical silicone material. When in use, the endotracheal tube is placed between the two clamping half rings and the clamping head is closed. The fastening assembly realizes the closing and locking of the clamping head. The endotracheal tube squeezes the arc-shaped clamping plate 66, causing the elastic plates 65 to deform. The elastic rebound force is used to achieve adaptive and non-destructive clamping of the endotracheal tube. When the elastic plates 65 show signs of fatigue and aging, the insert plate 652 can be removed for replacement and maintenance to ensure that the elastic plates 65 always have a stable clamping force.

[0062] The bottom of the opening and closing clamping head 6 is equipped with a lighting component. The lighting component includes an arc-shaped groove 67 opened on the bottom end face of the fixed clamping half ring 61 and the movable clamping half ring 62. An LED light board 68 is fixedly installed in the arc-shaped groove 67 by bolts. Several LED beads are arranged on the LED light board 68. It is directly connected to an external power supply through wires, or a rechargeable battery is installed on the base plate 1 to power the LED light board 68. The LED light board 68 is completely embedded without any exposed protrusions, so that the light is accurately directed towards the intubation area of ​​the patient's mouth and nose, realizing integrated soft light supplement for the intubation area of ​​the patient's mouth, which is suitable for low-light intubation scenarios.

[0063] A neck support assembly 7 is provided on the front side of the base 1, which can be adjusted relative to it. The neck support assembly 7 includes a neck support base plate 71, a flexible neck support 72 is fixedly installed on the top of the neck support base plate 71, and two guide holes 73 are symmetrically arranged on the side of the neck support base plate 71 facing the base 1. Two guide rods 74 are fixedly installed on the side of the base 1 facing the neck support base plate 71. The two guide rods 74 are coaxially corresponding to the two guide holes 73 and are inserted into the two guide holes 73 respectively to form a sliding fit, so that the neck support base plate 71 can slide back and forth along the two guide rods 74 to adjust its position.

[0064] A neck support base plate 71 has a neck support screw hole 75 in the middle of its side facing the base 1. A through hole is formed between the front and rear sides of the base 1, and a neck support adjustment rod 76 is rotatably installed in the through hole. The front end of the neck support adjustment rod 76 extends out of the through hole and extends to the front side of the base 1. A threaded section 77 is provided on the outer side of the extended end of the neck support adjustment rod 76. The threaded section 77 extends into the neck support screw hole 75 and forms a threaded engagement with it. A knob is coaxially fixedly installed at the rear end of the neck support adjustment rod 76. By rotating the neck support adjustment rod 76 through the knob, the threaded engagement between the threaded section 77 and the neck support screw hole 75 can drive the neck support base plate 71 to move back and forth precisely, adapting to different patients' neck lengths, supporting the patient's neck as needed to fully open the airway, and optimizing the intubation field of vision.

[0065] A method for using an integrated system for assisting in the fixation and illumination of anesthesia airway intubation includes the following steps:

[0066] a. Equipment clamping and positioning: Pull the two U-shaped buckles 23 outward to make the two buckle sliders 22 slide synchronously and compress the corresponding buckle springs 24. After aligning the base 1 and placing it on the side of the operating table, release the two U-shaped buckles 23 so that they elastically engage with the edge of the operating table. Then tighten the two buckle fixing bolts 26 to complete the locking and fixing. Place the patient's head on the headrest 101, rotate the neck support adjustment rod 76 to drive the neck support base plate 71 to slide smoothly back and forth along the guide rod 74, adjust the support position of the neck support 72, and lift the patient's neck to fully open the laryngeal airway.

[0067] b. Multi-angle pre-adjustment of the clamping head: Loosen the displacement positioning bolt 33, slide the two displacement sliders 3 synchronously along the two displacement grooves 31 to adjust the front and rear positions of the semi-circular C-shaped guide rail 4, and achieve positioning by tightening the displacement positioning bolt 33 after adjustment; Loosen the two angle positioning nuts 391, flip the semi-circular C-shaped guide rail 4 along the two semi-circular angle grooves 38 to the pitch angle that matches the patient's intubation tube, and tighten the two angle positioning nuts 391 to lock the positioning; Loosen the clamping positioning bolt 52, slide the arc-shaped slider 5 to drive the opening and closing clamping head 6 to align with the patient's oral intubation tube area, and tighten the clamping positioning bolt 52 to complete the final alignment and locking positioning.

[0068] c. Illumination and clamping fixation of intubation tube: Turn on the LED light panel 68 to provide local supplemental lighting for the patient's mouth and pharyngeal intubation area, eliminating blind spots in the dark vision; manually press the pressing block 645 to open the fastening assembly, then pry open the movable clamping half ring 62, place the inserted endotracheal tube between the two clamping half rings, close the movable clamping half ring 62, and the fastening assembly achieves automatic locking; the outer wall of the endotracheal tube compresses the arc-shaped clamping plate 66, causing the inclined elastic sheet 65 to undergo elastic deformation, relying on the elastic rebound force to self-adaptively and non-damagingly clamp and fix the endotracheal tube.

[0069] d. Intraoperative maintenance and postoperative disassembly: During the surgical anesthesia, the pitch angle of the semicircular C-shaped guide rail 4 and the arc position of the arc-shaped slider 5 can be slightly adjusted to compensate for the slight movement of the patient's head position, so as to keep the catheter clamping stable and avoid traction displacement. After the surgical operation is completed, press the pressing block 645 to unlock the fastening assembly, open the movable clamping half ring 62 to take out the endotracheal tube, loosen the two buckle fixing bolts 26, and pull the two U-shaped buckles 23 outward to release the lock between the base and the operating table. After the entire device is removed, it is cleaned, disinfected and stored for later use.
