Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to an inflatable headrest. Background Technology

[0002] During clinical surgery, various support tools are needed to stabilize the patient's posture, among which a head pillow is required to stabilize the patient's head. The head pillow elevates the patient's head, allowing them to lie naturally flat, and also prevents movement or swaying during surgery. Existing surgical head pillows have a circular structure. On the one hand, because these head pillows are made of polymer gel material, they are costly, easily damaged, and difficult to clean. Furthermore, if damaged, they may leak adhesive, potentially contaminating the surgical environment. On the other hand, because the structure and size of these head pillows are fixed and cannot be adjusted, their applicability is poor, providing inconsistent support for patients of different body types. To address these problems, this invention proposes an inflatable head pillow. Utility Model Content

[0003] The purpose of this invention is to provide an inflatable headrest in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] This utility model provides an inflatable headrest, including a headrest pad with a through groove in the center. The groove is a frustum-shaped structure that is wider at the top and narrower at the bottom with a smooth transition at the edge. Several air chambers are opened inside the headrest pad, and adjacent air chambers are interconnected. A self-sealing air vent assembly is connected to the headrest pad.

[0006] As a further optimization of this utility model, the headrest cushion includes a head support and a neck support. The upper surface of the neck support has an upwardly arched arc structure, and the top of the arc structure smoothly transitions to the head support.

[0007] As a further optimization of this utility model, the air chamber has a ring structure, and all the air chambers are distributed in a layered manner from the inside to the outside, with the size of the air chambers gradually increasing from the inside to the outside.

[0008] As a further optimization of this utility model, the air vent assembly is located on the outer surface of the headrest pad.

[0009] As a further optimization of this utility model, the air inlet assembly includes a fixed air tube communicating with the air chamber, an elastic sealing member disposed within the fixed air tube, and a movable air tube elastically slidably connected to the fixed air tube by a spring, with one end of the movable air tube located within the fixed air tube.

[0010] As a further optimization of this utility model, the elastic sealing member includes several elastic sealing pieces arranged in a spatial spiral. The elastic sealing pieces have a fan-shaped structure, and the outer arc surface of the elastic sealing pieces is fixed to the fixed air tube. The inner edges of adjacent elastic sealing pieces are stacked layer by layer.

[0011] As a further optimization of this utility model, an annular opening is provided between adjacent air cavities inside the headrest cushion.

[0012] As a further optimization of this utility model, the bottom of the headrest cushion is provided with an anti-slip pad.

[0013] The beneficial effects of this utility model are as follows:

[0014] This inflatable headrest, provided by this invention, features a central groove that is wider at the top and narrower at the bottom, allowing the patient's head to fit snugly against the headrest over a large area. This not only improves support stability and comfort but also distributes pressure evenly. Furthermore, the headrest has multiple air chambers inside to balance internal air pressure, effectively reducing the probability of damage due to excessive localized pressure and extending its lifespan. Through the coordination of the headrest pad, air chambers, and air vents, the headrest pad can be inflated and deflated to adjust its size, making it suitable for patients of various body types. This inflatable headrest is also washable, facilitating routine maintenance. Attached Figure Description

[0020] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1-4 As shown, the inflatable headrest of this embodiment includes a headrest pad 1, which is made of a waterproof and non-breathable material, preferably antibacterial silicone or antibacterial plastic. A through groove is provided in the center of the headrest pad 1. The groove has a frustum-shaped structure that is wider at the top and narrower at the bottom with a smooth transition at the edge. Several air chambers 2 are provided inside the headrest pad 1, and adjacent air chambers 2 are interconnected. A self-sealing air vent assembly 5 is connected to the headrest pad 1.

[0023] When using this inflatable headrest, on the one hand, the headrest pad 1 provides support for the patient's head. The groove in the center of the headrest pad 1 helps to fix the head angle, and the groove's structure, which is wider at the top and narrower at the bottom, better conforms to the patient's head structure, increasing the contact area between the patient's head and the headrest pad 1, resulting in better support stability, greater patient comfort, and also helping to distribute pressure and reduce the probability of damage to the headrest pad 1. The multiple air chambers 2 inside the headrest pad 1 can balance the internal air pressure, avoiding fatigue damage caused by sudden changes in local pressure in a single chamber, which helps to extend the service life of the headrest pad 1. On the other hand, the inflation and deflation of the headrest pad 1 can be adjusted through the air vent assembly 5, changing the internal inflation volume to adjust the size of the headrest pad 1, making it suitable for patients of different body types.

[0024] Preferably, the headrest 1 includes a head support 101 and a neck support 102. The upper surface of the neck support 102 has an upwardly arched arc structure, and the top of the arc structure smoothly transitions to the head support 101. The head support 101 and the neck support 102 can better conform to the physiological curvature between the cervical spine and the head, providing a more stable and comfortable support effect.

[0025] Preferably, the air chamber 2 has a ring structure, and all the air chambers 2 are distributed in an outer layer from the inside to the outside. The size of the air chamber 2 gradually increases from the inside to the outside. The structure of the air chamber 2 is set according to the structure of the headrest pad 1 of the corresponding part.

[0026] Preferably, the air vent assembly 5 is located on the outer side of the headrest 1, and the position of the air vent assembly 5 can avoid the patient's head, making it convenient to adjust the headrest 1 at any time.

[0027] Preferably, the air inlet assembly 5 includes a fixed air tube 501 communicating with the air chamber 2, an elastic sealing member 502 disposed in the fixed air tube 501, and a movable air tube 503 elastically slidably connected to the fixed air tube 501 by a spring 504. One end of the movable air tube 503 is located inside the fixed air tube 501. After the movable air tube 503 is pressed into the fixed air tube 501, the movable air tube 503 can push open the elastic sealing member 502 and communicate with the air chamber 2. At this time, exhaust or inflation operations can be performed from the movable air tube 503. After exhaust or inflation is completed, the movable air tube 503 is released, and the spring 504 will pop the movable air tube 503 out. The elastic sealing member 502 can then naturally return to the closed state and block the air chamber 2 again.

[0028] Preferably, the elastic sealing element 502 includes several elastic sealing sheets arranged in a spatial spiral. The elastic sealing sheets have a fan-shaped structure, and the outer arc surface of the elastic sealing sheets is fixed to the fixed air tube 501. The inner edges of adjacent elastic sealing sheets are stacked layer by layer. The elastic sealing sheets are preferably made of elastic silicone sheets. In the closed state, multiple elastic sealing sheets can be stacked to block the fixed air tube 501. When inflation or deflation is required, the movable air tube 503 can push open each elastic sealing sheet from the center. After the movable air tube 503 pops out, the elastic sealing sheets can automatically spring back to the initial stacked state and block the fixed air tube 501 again.

[0029] Preferably, an annular opening 3 is provided between adjacent air cavities 2 in the headrest cushion 1. The opening 3 provides a connection path for adjacent air cavities 2, so that air can be evenly ventilated in all parts of the air cavities 2, resulting in better uniformity of deformation in all directions of the headrest cushion 1.

[0030] Preferably, the bottom of the headrest pad 1 is provided with an anti-slip pad 4, which allows the inflatable headrest to be placed stably on the operating table.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
