Description

An auxiliary support structure for endotracheal intubation Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary support structure for endotracheal intubation. Background Technology

[0002] Endotracheal intubation is a common clinical procedure, especially in anesthesia, intensive care, and emergency medicine, used to ensure a patient's airway remains open. During intubation, a doctor inserts an endotracheal tube into the trachea through the mouth or nose to ensure the patient can breathe smoothly. However, after intubation, auxiliary devices are needed to secure the endotracheal tube to prevent displacement or dislodgement, thereby maintaining airway patency and reducing the occurrence of complications.

[0003] The existing endotracheal intubation support device has a fixed angle of the bite block during use, which cannot be adjusted according to the patient's oral cavity condition. In addition, the contact point between the device and the patient's skin is fixed, which causes the patient's local skin to be subjected to long-term pressure, resulting in low comfort when using the device. Summary of the Invention

[0004] In order to overcome the shortcomings of existing endotracheal intubation auxiliary support devices, such as the fixed angle of the bite pad and the fixed contact point between the device and the patient's skin, which leads to low user comfort, the technical problem of the present invention is to provide an auxiliary support structure for endotracheal intubation that can adjust the angle of the bite pad and change the contact point between the device and the patient's skin, thereby improving the user comfort of the device.

[0005] An auxiliary support structure for endotracheal intubation includes an arc-shaped mounting plate with a buckle. An elastic strap is provided at the end of the arc-shaped mounting plate away from the buckle. A tension band is snapped onto the buckle, and the tension band is provided with Velcro. A pad is connected between the elastic strap and the tension band. An arc-shaped rubber pad, a slide rail, and two circular rubber pads are provided on the arc-shaped mounting plate. A slider is slidably connected to the slide rail, and the slider is provided with a positioning mechanism, a rotating mechanism, and a fixing mechanism.

[0006] As an improvement to the above solution, the positioning mechanism includes an arc-shaped groove, an arc-shaped groove on the slide rail, several partitions evenly distributed on the arc-shaped groove, a guide block and a locking block slidably connected on the slider, a sliding groove on the guide block, a sliding connection between the locking block and the sliding groove on the guide block, and two return springs connecting the locking block and the slider.

[0007] As an improvement to the above solution, the rotating mechanism includes a mounting rod, a mounting rod slidably connected to the slider, a rotating block rotatably connected to the mounting rod, a sliding mounting block on the rotating block, a toothed pad slidably connected to the sliding mounting block, a fastening screw connected to the mounting rod by a thread, a rotating rod rotatably connected to the sliding mounting block, and a fixed rubber block on the rotating rod.

[0008] As an improvement to the above solution, the fixed rubber block is elliptical in shape, and the sliding mounting block is provided with a placement groove, in which a vent pipe is placed.

[0009] As an improvement to the above solution, the fixing mechanism includes a fixed rotating shaft, a fixed rotating shaft rotatably connected to the sliding mounting block, two spur gears on the fixed rotating shaft, a gear frame slidably connected to the sliding mounting block, the gear frame meshing with the two spur gears, several pressure springs connecting the gear frame and the sliding mounting block, and a cam on the fixed rotating shaft.

[0010] As an improvement to the above solution, several protrusions are provided on the fixed rotating shaft.

[0011] As an improvement to the above solution, an auxiliary mechanism is also included. The arc-shaped mounting plate is equipped with an auxiliary mechanism, which includes a rotating screw. Eight rotating screws are connected to the arc-shaped mounting plate by threads. Each rotating screw is rotatably connected to a fixed block. The fixed block and the arc-shaped mounting plate are slidably connected. Each fixed block is equipped with a movable rubber pad.

[0012] As an improvement to the above solution, it also includes telescopic belts. Two telescopic belts are provided on the arc-shaped mounting plate, and a chin support block is snapped between the two telescopic belts.

[0013] As an improvement to the above solution, it also includes wire-locking rubber strips, with four wire-locking rubber strips provided on the sliding mounting block.

[0014] The beneficial effects of this invention are: 1. Medical staff can open the patient's mouth to a certain distance and adjust the angle of the sliding mounting block and the dental pad by rotating the block, so that the dental pad is more suitable for being inserted into the patient's mouth. After the dental pad is adjusted to a suitable angle for being inserted into the patient's mouth, the medical staff can push the dental pad between the patient's upper and lower teeth, so that the patient's mouth will be opened to a certain distance, avoiding the patient biting the airway and causing the patient to suffocate. In this way, the dental pad can better adapt to the patient's oral condition and improve the comfort of the device.

[0015] 2. When providing oral care to patients, medical staff can install a pressure guide block to slide the slider along the arc-shaped mounting plate to one side of the patient's oral cavity, thereby facilitating the care of the patient's cavity and further improving work efficiency.

[0016] 3. For patients requiring long-term intubation, medical staff can periodically rotate the screw. Rotating the screw will cause the fixing block and sliding rubber pad to move closer to the patient's skin, allowing the sliding rubber pad to come into contact with the patient's skin and thus detaching the arc-shaped rubber pad from the patient. In this way, the support point of the arc-shaped mounting plate on the patient's face can be changed, avoiding long-term pressure on the patient's local skin and further improving the comfort of the device.

Detailed Implementation

[0029] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0030] Example 1: An auxiliary support structure for endotracheal intubation, as shown in Figures 1-9, includes an arc-shaped mounting plate 1, a buckle 2 on the arc-shaped mounting plate 1, an elastic strap 3 at the end of the arc-shaped mounting plate 1 away from the buckle 2, a tension strap 4 snapped onto the buckle 2, a Velcro fastener on the tension strap 4, a support pad 5 connecting the elastic strap 3 and the tension strap 4, an arc-shaped rubber pad 6, a slide rail 8 and two circular rubber pads 7 on the arc-shaped mounting plate 1, a slider 9 slidably connected to the slide rail 8, and a positioning mechanism, a rotating mechanism and a fixing mechanism on the slider 9.

[0031] The positioning mechanism includes an arc-shaped groove 111. The slide rail 8 is provided with an arc-shaped groove 111. Several partitions are evenly provided on the arc-shaped groove 111. The slider 9 is slidably connected to a guide block 112 and a locking block 113. The guide block 112 is provided with a sliding groove. The locking block 113 is slidably connected to the sliding groove on the guide block 112. Two return springs 114 are connected between the locking block 113 and the slider 9.

[0032] The rotating mechanism includes a mounting rod 121, a sliding block 122 connected to the slider 9, a rotating block 122 connected to the mounting rod 121, a sliding mounting block 123 on the rotating block 122, a toothed pad 124 slidably connected to the sliding mounting block 123, a fastening screw 127 threadedly connected to the mounting rod 121, a rotating rod 125 rotatably connected to the sliding mounting block 123, and a fixed rubber block 126 on the rotating rod 125.

[0033] The fixed rubber block 126 is elliptical in shape, and the sliding mounting block 123 is provided with a placement groove, in which a vent pipe 10 is placed.

[0034] The fixing mechanism includes a fixed rotating shaft 131, a sliding mounting block 123 rotatably connected to the fixed rotating shaft 131, two spur gears 132 on the fixed rotating shaft 131, a gear frame 133 slidably connected to the sliding mounting block 123, the gear frame 133 meshing with the two spur gears 132, a number of pressure springs 134 connected between the gear frame 133 and the sliding mounting block 123, and a cam 135 on the fixed rotating shaft 131.

[0035] The fixed rotating shaft 131 has several protrusions.

[0036] Initially, the locking block 113 is engaged in the arc-shaped slot 111, locking the slider 9. After the patient completes endotracheal intubation, the medical staff places the arc-shaped mounting plate 1 centered between the patient's nose and upper lip, ensuring the arc-shaped rubber pad 6 and the circular rubber pad 7 are in contact with the patient's skin. Then, the medical staff wraps the elastic band 3, tension band 4, and support pad 5 around the back of the patient's head. The medical staff passes the tension band 4 through the buckle 2 and pulls the tension band 4, initially fixing the arc-shaped mounting plate 1 to the patient's face. The medical staff then bends the tension band 4, causing it to adhere to itself, thus initially fixing the arc-shaped mounting plate 1 to the patient's face. Subsequently, the medical staff presses the guide block 112, causing it to extend into the slider 9, whereby the guide block 112 compresses the locking block. 113, causing the locking block 113 to extend into the slider 9, compressing the return spring 114, disengaging the locking block 113 from the arc-shaped groove 111, and freeing the slider 9 from locking. Medical personnel can then slide the slider 9 to a suitable position. The movement of the slider 9 causes the mounting rod 121, rotating block 122, sliding mounting block 123, dental pad 124, rotating rod 125, fixing rubber block 126, and fastening screw 127 to move together. After the slider 9 reaches the suitable position, the medical personnel release the guide block 112, causing the return spring 114 to reset, which in turn resets the locking block 113 and guide block 112. The reset locking block 113 then re-engages into the arc-shaped groove 111, locking the slider 9 again. Then, the medical personnel open the patient's mouth to a certain distance. Caregivers can adjust the angles of the sliding mounting block 123 and the mouthguard 124 by rotating block 122, making the mouthguard 124 more suitable for insertion into the patient's mouth. After adjusting the mouthguard 124 to the appropriate angle, the caregiver pushes the mouthguard 124 between the patient's upper and lower teeth, thus opening the patient's mouth to prevent the patient from biting down on the air tube 10 and suffocating. In this way, the mouthguard 124 can better adapt to the patient's oral cavity, improving the comfort of the device. After placing the mouthguard 124, the caregiver first rotates the fastening screw 127, so that the fastening screw 127 contacts the rotating block 122, thereby fixing the angle of the rotating block 122. Then, the caregiver places the air tube 10 on the sliding mounting block. In the placement slot of 123, medical staff rotate the rotating rod 125. The rotation of the rotating rod 125 causes the fixed rubber block 126 to rotate 90 degrees, so that the fixed rubber block 126 comes into contact with the mouthguard 124 and is deformed by the mouthguard 124, thereby fixing the position of the mouthguard 124 on the sliding mounting block 123. During the rotation of the rotating rod 125, the cam 135 rotates, and the cam 135 compresses the gear frame 133, causing the gear frame 133 to move away from the rotating rod 125. The pressure spring 134 is compressed. During the movement of the gear frame 133, it meshes with the spur gear 132, causing the spur gear 132 to rotate. The rotation of the spur gear 132 drives the fixed rotating shaft 131 to rotate, and the fixed rotating shaft 131 comes into contact with the ventilation tube 10.The fixed pivot 131 secures the air tube 10 in the placement groove of the sliding mounting block 123. The protrusions on the fixed pivot 131 allow the air tube 10 to slide, thus quickly fixing the air tube 10 and improving the efficiency of medical staff. After fixing the air tube 10, medical staff need to pull the tension band 4 open and then tighten it, stretching the elastic band 3 until the gap between the elastic band 3 and the patient's skin is only one finger's width. Then, the medical staff re-adhere the tension band 4 to itself, firmly fixing the arc-shaped mounting plate 1 to the patient's face, completing the fixation of the air tube 10. When performing oral care, medical staff can install the pressure guide block 112 to slide the slider 9 along the arc-shaped mounting plate 1 to one side of the patient's mouth, thereby... To facilitate nursing care of the patient's cavity and further improve work efficiency, during disassembly, the nursing staff first reverses the rotation rod 125. The resetting of the rotation rod 125 will cause the fixed rubber block 126 and the cam 135 to reset. The resetting of the fixed rubber block 126 will disengage from the bite pad 124. The resetting of the cam 135 will no longer compress the toothed frame 133. The resetting of the pressure spring 134 will cause the toothed frame 133 to reset. The resetting of the toothed frame 133 will cause the column gear 132 to rotate and reset. The resetting of the column gear 132 will cause the fixed rotating shaft 131 to rotate and reset, disengaging the fixed rotating shaft 131 from the ventilation tube 10. The nursing staff can then remove the bite pad 124 from the patient's cavity. Next, the nursing staff will remove the ventilation tube 10 from the slot of the sliding mounting block 123, remove the tension band 4 from the buckle 2, and remove the arc-shaped mounting plate 1 from the patient's face, completing the disassembly.

[0037] Example 2: Based on Example 1, as shown in Figures 10-11, an auxiliary mechanism is also included. The arc-shaped mounting plate 1 is provided with an auxiliary mechanism, which includes a rotating screw 141. Eight rotating screws 141 are connected to the arc-shaped mounting plate 1 by threads. Each rotating screw 141 is rotatably connected to a fixing block 142. The fixing block 142 and the arc-shaped mounting plate 1 are slidably connected. Each fixing block 142 is provided with a movable rubber pad 143.

[0038] It also includes a telescopic belt 15, and two telescopic belts 15 are provided on the arc-shaped mounting plate 1, with a chin support block 16 snapped between the two telescopic belts 15.

[0039] It also includes wire-locking rubber strips 19, and four wire-locking rubber strips 19 are provided on the sliding mounting block 123.

[0040] After securing the dental pad 124 and the ventilation tube 10, the medical staff aligns the chin support block 16 with the patient's chin. Then, the medical staff pulls the telescopic straps 15 at both ends of the arc-shaped mounting plate 1 to engage with the ends of the chin support block 16, thereby enhancing the stability of the arc-shaped mounting plate 1. For patients requiring long-term intubation, the medical staff can periodically rotate the rotating screw 141. Rotating the screw 141 will cause the fixing block 142 and the sliding rubber pad to move closer to the patient's skin, allowing the sliding rubber pad to contact the patient's skin and thus detaching the arc-shaped rubber pad 6 from the patient. This method changes the support point of the arc-shaped mounting plate 1 on the patient's face, preventing long-term pressure on the patient's local skin and further improving the comfort of the device. During intubation, some small catheters can be secured by the wire-locking rubber strip 19 at the bottom of the sliding mounting block 123.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing 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 invention should be included within the protection scope of the present invention.
