Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an adjustable airway opening fixer. Background Art

[0002] At present, when performing cardiopulmonary resuscitation on patients with cardiac arrest during out-of-hospital emergency treatment, the airway is mostly opened manually. This method can neither ensure the fixation of the patient's head nor keep the patient's airway open. It may also cause cervical spine injury and aspiration, seriously affecting the resuscitation effect during the emergency treatment process.

[0003] While some devices exist to prevent tongue posterior prolapse and assist in airway opening, these devices typically utilize a saddle-shaped support structure tailored to the human neck's anatomical structure. The lower support plate rests on the clavicle, while the upper support plate supports the chin, placing the neck in a physiologically extended position. This pulls the tongue muscles forward, preventing tongue posterior prolapse and airway obstruction. The rear ends of the support are connected by a bolster strap to maintain the front of the neck support in place. This can address the aforementioned issue to a certain extent.

[0004] However, existing auxiliary airway opening devices have no adjustment function, cannot adjust the support height, and the rear pillow cannot be adjusted. It cannot meet the needs of patients with different body shapes, nor can it meet the clinical needs of comatose patients who need to tilt their heads to one side to prevent aspiration.

[0005] Therefore, there is an urgent need for an adjustable airway opening fixator to solve at least one of the above problems. Utility Model Content

However, for those skilled in the art, these embodiments are only examples, and the general principles defined herein may be applied to other embodiments and application scenarios without departing from the spirit and scope of the present invention.

[0031] According to an exemplary embodiment of the present invention: Figure 1-9 As shown, an adjustable airway opening fixator includes: a mandibular support device and a head and neck support device 30, the mandibular support device includes a first support plate 10 and a second support plate 20, the first support plate 10 can be rotated and adjusted relative to the second support plate 20; the head and neck support device 30 is a split structure, including a headrest support plate 31 and a neck support plate 32, the headrest support plate 31 can be adjusted in position relative to the neck support plate 32.

[0032] The head and neck support device 30 is detachably fixedly connected to the mandibular support device via an adjustable strap. The adjustable strap may also be referred to as a fastening strap 38. The exemplary adjustable strap may be an elastic band or a strap of adjustable length, thereby fastening and securing the two to the human body.

[0033] like Figure 8, 9, the headrest support plate 31 can be adjusted up and down in the vertical direction relative to the neck support plate 32; the headrest support plate 31 can be rotated and adjusted in the horizontal direction relative to the neck support plate 32.

[0034] like Figure 8 , as shown in FIG9 , it also includes a first fixing pin 34 , an arc-shaped receiving groove 33 is formed on the neck support plate 32 , and a plurality of groups of first holes 35 are formed on the outer peripheral surface of the receiving groove 33 ; wherein the plurality of groups of first holes are arranged in an array in the horizontal direction and the vertical direction.

[0035] The headrest support plate 31 is formed with a protrusion 37 that cooperates with the receiving groove 33. The protrusion 37 can slide along the receiving groove 33. A plurality of second holes 36 are formed on the protrusion 37; wherein the plurality of second holes are evenly distributed in the vertical direction. The first fixing pin 34 can pass through the first hole 35 and the second hole 36 to fix the headrest support plate 31 and the neck support plate 32. Optionally, the first fixing pin 34 is tightly fitted with the first hole 35 and the second hole 36 to prevent it from falling off abnormally. Figure 8 As shown in FIG9 , multiple second holes 36 are arranged vertically; multiple groups of first holes 35 are distributed in an array along the horizontal and vertical directions; through the cooperation between the first holes 35 and the second holes 36, horizontal and vertical adjustments are achieved. This satisfies the needs of people with different characteristics.

[0036] like Figure 1 , 2, 6, and 7, further comprising a second fixing pin 22. A plurality of third holes 11 are formed on the first support plate 10, and a plurality of fourth holes 21 are formed on the second support plate 20. The schematic third holes 11 and fourth holes 21 are evenly distributed along the circumferential direction. The second fixing pin 22 can pass through the third holes 11 and the fourth holes 21 to achieve rotational fixation of the first support plate 10 and the second support plate 20. Exemplarily, the second support plate 20 is fixedly connected to a rotation shaft 23, and the first support plate 10 is formed with a rotation hole that cooperates with the rotation shaft 23.

[0037] Although the number of the first fixing pin 34 and the second fixing pin 22 is schematically shown as one, it is obvious that multiple ones can also be provided for more stable fixation.

[0038] like Figure 1-4 As shown, the first support plate 10 is a U-shaped structure that can be supported on both sides of the human clavicle. The second support plate 20 is a U-shaped structure that can be supported on the human mandible, with a relatively straight portion formed in the middle upper part to facilitate the neck to rest.

[0039] like Figure 1-4 As shown, the head and neck support device 30 has a curved structure that can fit the human neck. Its overall arc-shaped structure fits the human neck. Its upper middle part is formed with a straight section to facilitate the support of the human head.

[0040] like Figure 1-9 As shown, when the present invention is used, the first fixing pin 34 is pulled out, the headrest support plate 31 is pulled to move to a suitable position relative to the neck support plate 32, and the first fixing pin 34 is reinstalled to lock the position.

[0041] Pull out the second fixing pin 22, rotate the second support plate 20 and the first support plate 10 to a suitable angle, reinstall the second fixing pin 22, and lock the position.

[0042] During use, when the head needs to be deflected, such as when sleeping, when the head needs to be deflected to one side, at this time, pull out the first fixing pin 34, the headrest support plate 31 is rotated to one side relative to the neck support plate 32, and the first fixing lock 34 is reinstalled to lock the position.

[0043] The adjustable airway opening fixator of this utility model comprises a first support plate 10 and a second support plate 20 that can rotate relative to each other, and a headrest support plate 31 and a neck support plate 32 that can be adjusted relative to each other in the vertical direction, thereby accommodating patients of various body shapes. Furthermore, the relative rotation of the headrest support plate 31 and the neck support plate 32 can accommodate patients who tilt their head to one side or sleep with their head tilted to one side, thereby improving patient comfort.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments and combinations of elements without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
