Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, specifically to an adjustable ear pressure protection strap. Background Technology

[0002] Bedridden individuals are prone to developing pressure sores when in prolonged bed rest, which can potentially lead to localized necrosis. The ear, with its numerous capillaries and frequent pressure points during bed rest, is particularly vulnerable to pressure sores. While frequent turning is a common preventative measure, relying solely on caregivers for regular turning is impractical. Therefore, a solution to the problem of pressure sores on the ear caused by prolonged side-lying position is urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable ear pressure protection strap to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable ear pressure protection strap, comprising:

[0005] Neck support pillow;

[0006] A slider with symmetrically slidable ear pad support components.

[0007] The headband restraint strap has a first flexible connecting strap that is fixedly installed on the back of the headband and is fixedly attached to the second flexible connecting strap that is fixedly set on the neck support pillow by Velcro;

[0008] The slide bar is fixed to the second flexible connecting strip.

[0009] Preferably, the headband strap has a hook and loop side on one side of its end.

[0010] Preferably, the skin-friendly surface of the neck support pillow is provided with an inflatable air bladder, which is connected to an inflatable air nozzle on the surface of the neck support pillow.

[0011] Preferably, the slider is composed of a shape memory alloy and a silicone outer sheath covering the outer surface of the shape memory alloy.

[0012] Preferably, the ear pad support includes an elastic C-shaped slide sleeve that slides on the slide bar and is limited by a protrusion on the port that is embedded in a waist hole on the back of the slide bar.

[0013] Preferably, the elastic C-shaped slide has a plane, and the ear pad support includes arc-shaped ear pads symmetrically mounted on the plane, with an ear-receiving area formed between the two arc-shaped ear pads.

[0014] Preferably, the two arc-shaped ear pads on one of the elastic C-shaped slides face the same direction, while the arc-shaped ear pads on the two elastic C-shaped slides face opposite directions.

[0015] Preferably, a suction cup is provided in the center of the surface of the arc-shaped ear pad.

[0016] Preferably, the arc-shaped ear pad is made of rubber, and the skin-friendly surface has an arc-shaped structure.

[0017] In the above technical solution, the adjustable ear pressure protection band provided by this utility model has the following beneficial effects: by pressing the slider made of shape memory alloy, it deforms and fits the patient's head, and then by sliding the ear pad support, the position of the patient's ear canal is found, thereby providing soft contact to the ear.

[0018] Secondly, the combination of the neck support pillow and the headband restraint strap can ensure that the position of the ear pad support is maintained after fixation.

[0019] Furthermore, the ear pressure protection strap has an exposed design to ensure normal heat dissipation from the patient's head. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-3 As shown, an adjustable ear pressure protection strap includes:

[0028] Neck support pillow 1;

[0029] Slider 2, on which ear pad support members 3 are symmetrically slidably mounted.

[0030] The headband restraint strap 4 has a first flexible connecting strap 5 that is fixed to the second flexible connecting strap 6 fixedly set on the neck support pillow 1 by Velcro;

[0031] Among them, the slide bar 2 is fixed on the second flexible connecting strip 6.

[0032] Specifically, slider 2 is composed of a shape memory alloy and a silicone outer sheath covering the outer surface of the shape memory alloy. Therefore, slider 2 can be bent as needed and remain in the bent state, thus making slider 2 suitable for patients with different head circumferences.

[0033] Secondly, in this embodiment, the distance between the headband restraint strap 4 and the slide strip 2 can be changed by the first flexible connecting strap 5 and the second flexible connecting strap 6, thereby adapting to patients with different head lengths.

[0034] Furthermore, both the first flexible connecting strip 5 and the second flexible connecting strip 6 mentioned above are nylon strips.

[0035] The aforementioned fixing and installation can be done using any combination method known to those skilled in the art, such as sewing or adhesive bonding.

[0036] Furthermore, in the above embodiment, the headband restraint strap 4 has a hook side and a loop side on one side of its end, which allows the girth of the headband restraint strap 4 to be variable, thereby securing it to the patient's head.

[0037] In the above technology, a slider 2 made of shape memory alloy is pressed to deform and fit the patient's head, and then the ear pad support 3 is slid to find the patient's ear canal position, thereby providing soft contact to the ear.

[0038] Secondly, the neck support pillow 1 and the headband restraint strap 4 work together to ensure that the position of the ear pad support 3 is maintained after fixation.

[0039] As a further embodiment of this utility model, combined with Figure 1It can be seen that the skin-friendly surface of the neck pillow 1 is provided with an inflatable airbag 7, and the inflatable airbag 7 is connected to the inflatable air nozzle 71 provided on the surface of the neck pillow 1.

[0040] Specifically, remove the plug from the inflation nozzle 71, and then use a syringe to inflate it, which will cause the airbag 7 to expand and fit against the patient's neck, providing support for the neck and preventing neck muscle fatigue caused by being suspended in the air.

[0041] As another embodiment further provided by this utility model, combined with Figure 1 and Figure 2 As shown, the ear pad support 3 includes an elastic C-shaped slide sleeve 31, which slides on the slide strip 2 and is limited by a protrusion 32 provided on the port, which is embedded in the waist hole 21 opened on the back of the slide strip 2.

[0042] Specifically, in the embodiment, the ear pad support 3 is assembled on the slide bar 2 by an elastic C-shaped sliding sleeve 31, and the elastic C-shaped sliding sleeve 31 is a plastic part, which is separated from the slide bar 2 by disengaging the protrusion 32 from the waist hole 21.

[0043] Secondly, the waist hole 21 in the embodiment is used to limit the sliding stroke of the C-shaped sleeve 31.

[0044] As another embodiment further provided by this utility model, combined with Figure 1 As shown, the elastic C-shaped slide 31 has a plane, and the ear pad support 3 includes arc-shaped ear pads 34 symmetrically mounted on the plane, with an ear-receiving area 33 formed between the two arc-shaped ear pads 34.

[0045] Furthermore, a suction cup 341 is centrally located on the surface of the curved ear pad 34.

[0046] Specifically, in the above embodiment, when the ear pad support 3 is worn, the patient's ear is located within the ear-receiving area 33, while the arc-shaped ear pads 34 are distributed on both sides of the patient's ear. The arc-shaped ear pads 34 are used as support, so that the patient's ear is suspended in the ear-receiving area 33.

[0047] The suction cup 341 will adhere to the patient's skin, thereby fixing the curved ear pad 34 to both sides of the patient's ear.

[0048] As another embodiment further provided by this utility model, combined with Figure 1 As shown, the two arc-shaped ear pads 34 on one elastic C-shaped slide 31 face the same direction, while the arc-shaped ear pads 34 on the two elastic C-shaped slides 31 face opposite directions.

[0049] Secondly, the curved ear pad 34 is made of rubber, and the skin-friendly surface has a curved structure.

[0050] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
