[0029] Example 1
[0030] A medical head restraint device to prevent aspiration, such as Figure 1 As shown, it includes a base plate 1, a head support plate 2 fixed to the top of the base plate 1, a side plate 3 on one side of the head support plate 2, the bottom of the side plate 3 being fixedly connected to the base plate 1, a first inflatable airbag 301 fixed to the side plate 3 near the head support plate 2, a sponge pad 302 on the side of the first inflatable airbag 301 away from the side plate 3, the first inflatable airbag 301 being connected to a first compression airbag 304 through a first inflation pipe 303, and an exhaust valve installed on the first inflation pipe 303.
[0031] The base plate 1 has straps 4 fixed to both ends. The ends of the two straps 4 are tied together or connected by buckles. The straps 4 are made of elastic material, and the buckles are commercially available plastic or metal buckles. In use, the base plate 1 is placed on the hospital bed, and the two straps 4 are wrapped around the bottom of the hospital bed and fixed by buckles or knots to secure the base plate 1 to the hospital bed.
[0032] The head support plate 2 is equipped with a head support pad 201, which is a conventional latex pillow covered with a pillowcase. The head support pad 201 is connected to the head support plate 2 via Velcro, making it easy to disassemble, clean, and replace.
[0033] The base plate 1, head support plate 2, and side plate 3 are all made of plastic, and all three are covered with waterproof cloth. The inner lining of the waterproof cloth is a sponge layer with a certain thickness.
[0034] The method of using the medical anti-aspiration head fixation device in this embodiment is as follows: First, place the base plate 1 on the hospital bed and fix it to the hospital bed with two straps 4. Then, place the patient's head on the head support pad 201, so that it is biased away from the side plate 3. Finally, squeeze the first compression air bag 304 to inflate the first inflation air bag 301, so that the sponge pad 302 fits tightly against the patient's neck and head, thus completing the fixation of the patient's head.
[0035] Example 2
[0036] A medical anti-aspiration head fixation device, the technical solution of this embodiment is basically the same as that of embodiment 1, the difference is that: (1) the tilt angle of the head support plate 2 in this embodiment is adjustable; (2) a forehead strap 6 is also provided on the head support pad 201.
[0037] like Figure 2 As shown, in this embodiment, an adjustment plate 5 is provided on the top of the base plate 1. The head support plate 2 and the side plate 3 are fixed on the adjustment plate 5. One end of the adjustment plate 5 near the shoulder of the human body is rotatably connected to the base plate 1 via a pivot or hinge. A second inflatable airbag 501 is fixed to the bottom of the other end of the adjustment plate 5. A groove is provided on the base plate 1, and the bottom of the second inflatable airbag 501 is fixed in the groove. The second inflatable airbag 501 is connected to a second compression airbag 503 through a second inflation pipe 502. An exhaust valve is installed on the second inflation pipe 502. The tilt angle of the adjustment plate 5 is adjusted by the change in air pressure inside the second inflatable airbag 501, thereby adjusting the tilt angle of the head support plate 2 and the side plate 3, which is convenient for adjustment according to the different needs of different types of patients.
[0038] like Figure 3As shown, a forehead strap 6 is provided at the position corresponding to the forehead on the head support pad 201, with the middle part of the forehead strap 6 sewn onto the head support pad 201. One end of the forehead strap 6 has multiple square loops 601 along its length, and the other end has a first hook-and-loop fastener surface 602 and a first hook-and-loop fastener hook surface 603 along its length. One end of the forehead strap 6 passes through one of the square loops 601, allowing the first hook-and-loop fastener surface 602 and the first hook-and-loop fastener hook surface 603 to fit together. The forehead strap 6 is used to fix the patient's forehead to the head support pad 201, increasing stability. The multiple square loops 601 facilitate adjustment according to the patient's head circumference.
[0039] Example 3
[0040] A medical anti-aspiration head fixation device, the technical solution of this embodiment is basically the same as that of embodiment 1 or 2, the difference is that: this embodiment also provides a neck support pad 7.
[0041] like Figure 4 and Figure 5 As shown, the neck support pad 7 is detachably connected to the base plate 1. Connecting straps 701 are fixed to the outer ends of the neck support pad 7. The base plate 1 has a fixing strap 101 on the side wall near the human shoulder. The left and right ends of the fixing strap 101 are fixedly connected to the base plate 1. A second hook and loop fastener 702 is sewn on the inner side of the free end of the connecting strap 701. A second hook and loop fastener 703 is sewn on the outer side of the fixed end of the connecting strap 701. The free end of the connecting strap 701 passes through the fixing strap 101 and wraps around the neck support pad 7 once, so that the second hook and loop fastener 702 and the second hook and loop fastener 703 are attached.
[0042] The neck support pad 7 is detachably connected to the base plate 1. Patients can choose to use the neck support pad or not according to their different needs, which can meet their treatment needs and is also easy to replace and clean.
[0043] Example 4
[0044] A medical head restraint device to prevent aspiration, such as Figure 6 As shown, the technical solution in this embodiment is consistent with any of the technical solutions in embodiments 1-3, except that: this embodiment also includes a vomit discharge device.
[0045] An inclined section 8 is fixed to the side of the head support plate 2 away from the side plate 3. The inclined section 8 is fixedly connected to the base plate 1 and flush with the end of the base plate 1. The inclined angle of the inclined section 8 is downward. A vomit discharge device is provided on the side wall of the base plate 1. The vomit discharge device includes a receiving plate 9. The side wall of the base plate 1 has a cavity communicating with the outside. The receiving plate 9 is slidably connected in the cavity. The inner bottom wall of the receiving plate 9 is inclined downward. A discharge port 901 is provided at the end of the receiving plate 9 away from the head support plate 2. In use, after fixing the patient's head, the receiving plate 9 is pulled out from the base plate 1 so that the discharge port 901 is located outside the bed. A trash can can be placed below the discharge port 901. When the patient vomits, the vomit falls directly into the trash can from the discharge port 901 on the receiving plate 9.
[0046] This utility model provides a medical anti-aspiration head fixation device that is secured to the hospital bed with straps, ensuring stable placement and preventing displacement during use. When in use, the patient's head is tilted away from the side panel, and the first inflatable airbag inflates to ensure the sponge pad fits snugly against the patient's head and neck, preventing aspiration and ensuring patient safety. A forehead strap on the head support pad further secures the head to the patient's forehead, increasing stability and reducing head movement, thus enhancing fixation. The head support pad is height-adjustable, allowing for flexible adjustment to a suitable angle based on individual patient needs and physical conditions, improving adaptability. The neck support pad is detachable, allowing patients to choose whether to use it, meeting individual needs and improving comfort. A vomit discharge device allows vomit to fall directly into a trash can through an inclined receiving tray, facilitating cleaning, reducing the workload of medical staff, maintaining a clean environment around the bed, and preventing contamination and odor caused by vomit residue.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
