Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically to a neck decompression device. Background Technology

[0002] In modern medical settings, patients who are bedridden for extended periods face numerous health challenges, with cervical spine comfort and pressure ulcer prevention being particularly critical. For patients who are unable to move for extended periods due to illness or accidents, the cervical spine endures immense pressure from maintaining a fixed posture for extended periods. This not only leads to cervical muscle tension and poor blood circulation but can also cause serious pressure ulcers. Pressure ulcers are caused by prolonged pressure on the skin, resulting in impaired blood circulation and subsequent damage to the skin and subcutaneous tissues. In severe cases, they can even lead to serious consequences such as infection and sepsis.

[0003] Currently, while there are some decompression devices on the market for bedridden patients, such as air mattresses and turning mats, most of these devices focus on overall decompression or localized turning, with limited effectiveness in specifically relaxing the cervical spine and preventing pressure sores. Therefore, developing a cervical decompression bed that can precisely decompress and relax the cervical spine while effectively reducing the risk of pressure sores is particularly important. Utility Model Content

[0004] This invention provides a neck decompression device, which has the beneficial effect of relaxing the cervical spine of patients who cannot move for a long time, while further reducing the risk of pressure sores in the cervical spine area.

[0005] A neck decompression device includes a bed frame with a mounting groove on one side, in which a cervical pillow is installed. Two through grooves are symmetrically formed in the middle of the cervical pillow, and two arc-shaped grooves are symmetrically formed on the arc-shaped surface at the upper end of the cervical pillow, each arc-shaped groove communicating with one of the through grooves. Arc-shaped plates are slidably connected within each of the arc-shaped grooves. The device also includes an I-shaped roller frame, with vertical sliding grooves at both ends of the two through grooves. The four corners of the I-shaped roller frame are slidably connected to four vertical sliding grooves. An electric push rod is installed between the I-shaped roller frame and the bottom surface of the cervical pillow. Two massage rollers are symmetrically rotatably connected to the I-shaped roller frame, each massage roller located within one of the two through grooves. Two motors II are fixedly connected to the I-shaped roller frame, and the two massage rollers are connected to the output shafts of the two motors II via couplings.

[0006] The cervical pillow has side sliding grooves on both sides of the two arc-shaped grooves, and ear plates are formed at both ends of the two arc-shaped plates. The four ear plates are slidably connected in the corresponding side sliding grooves.

[0007] The bottom surface of the cervical pillow is symmetrically fixed with two motors I, and the output shafts of the two motors I are fixed with gears. The bottom surfaces of the two arc-shaped plates are fixed with arc-shaped racks, and the two arc-shaped racks are respectively meshed with the two gears for transmission.

[0008] A headrest is installed on the bed frame to fit the position of the cervical spine pillow. Attached Figure Description

Detailed Implementation

[0022] See Figures 1 to 9 The diagram shows an embodiment of cervical spine massage according to the present invention.

[0023] A neck decompression device includes a bed 101 with a mounting groove 102 on one side, in which a cervical pillow 201 is installed. Two through grooves 202 are symmetrically formed in the middle of the cervical pillow 201, and two arc-shaped grooves 203 are symmetrically formed on the arc-shaped surface at the upper end of the cervical pillow 201. The two arc-shaped grooves 203 are respectively connected to the two through grooves 202, and arc-shaped plates 303 are slidably connected within each of the two arc-shaped grooves 203. The device also includes an I-shaped roller frame 401, with a roller at each end of the two through grooves 202. The vertical sliding groove 205 and the four corners of the I-shaped roller frame 401 are slidably connected in the four vertical sliding grooves 205 respectively. An electric push rod 206 is installed between the bottom surface of the I-shaped roller frame 401 and the cervical pillow 201. Two massage rollers 403 are symmetrically rotatably connected on the I-shaped roller frame 401. The two massage rollers 403 are respectively located in two through grooves 202. Two motors II 402 are fixed on the I-shaped roller frame 401. The two massage rollers 403 are respectively connected to the output shafts of the two motors II 402 through couplings.

[0024] A bedridden patient with cervical spine injury lies on bed 101 with the cervical spine located inside cervical pillow 201. Cervical pillow 201 supports the neck. The top surface of cervical pillow 201 is designed to be curved to better fit the neck and provide better support. Normally, two curved plates 303 are located inside the two curved grooves 203, blocking the two through grooves 202. The top surfaces of the two curved plates 303 are coplanar with the top surface of cervical pillow 201, thus providing a more comfortable user experience for the patient.

[0025] When the two curved plates 303 slide open in opposite directions within the two curved grooves 203, the two through grooves 202 are exposed. At this time, the cervical spine can be ventilated and soothed. At the same time, the contact area between the cervical pillow 201 and the cervical spine is reduced, which can relax the skin surface and improve blood flow, thereby reducing the risk of pressure sores in the cervical spine area.

[0026] After the two curved plates 303 are opened, the electric push rod 206 is powered on and started. The telescopic end of the electric push rod 206 retracts, driving the I-shaped roller frame 401 to move upward. The I-shaped roller frame 401 drives the two massage rollers 403 to move upward to contact the skin of the cervical spine. The two motors II 402 are started, driving the two massage rollers 403 to rotate back and forth in a small amplitude, thereby massaging the cervical spine, relaxing the cervical spine that cannot be moved for a long time, and further reducing the risk of pressure sores.

[0027] See Figure 5 and 6 The diagram shows an embodiment of the sliding limit of the arc plate 303 according to the present invention;

[0028] The cervical pillow 201 has side sliding grooves 204 on both sides of the two arc-shaped grooves 203, and ear plates 305 are formed at both ends of the two arc-shaped plates 303. The four ear plates 305 are slidably connected in the corresponding side sliding grooves 204.

[0029] The ear plate 305 cooperates with the side slide groove 204 to guide and limit the sliding trajectory of the arc plate 303, so that the arc plate 303 can slide along the arc trajectory in the arc groove 203 to open or close the through groove 202.

[0030] See Figure 6 and 7 The diagram shows an embodiment of controlling the opening or closing of the arc plate 303 according to the present invention;

[0031] The bottom surface of the cervical pillow 201 is symmetrically fixed with two motors I 301, and the output shafts of the two motors I 301 are fixed with gears 302. The bottom surfaces of the two arc-shaped plates 303 are fixed with arc-shaped racks 304, and the two arc-shaped racks 304 are respectively meshed with the two gears 302 for transmission.

[0032] When the two motors I301 are started, they drive the two gears 302 to rotate. The two gears 302, through meshing with the two arc-shaped racks 304, drive the two arc-shaped plates 303 to slide outward to open or slide inward to close.

[0033] See Figure 1 The diagram shows an embodiment of supporting a patient's head according to the present invention.

[0034] A headrest 104 is installed on the bed 101 at the position of the cervical pillow 201; the headrest 104 is used to support and bolster the patient's head.

[0035] See Figure 2 and 10 The diagram shows an embodiment of the head ventilation and heat dissipation according to the present invention.

[0036] The headrest 104 has four symmetrical slots 105, and the bed frame 101 has ventilation holes 103 corresponding to the four slots 105.

[0037] The ventilation port 103 is connected to the slot 105 to allow ventilation for the head, preventing pressure sores from forming on the head when the patient is lying down for a long time and is unable to move, or preventing effective sweating and heat dissipation when sweating.

[0038] See Figure 10 and 11 The diagram shows an embodiment of opening or closing the slot 105 according to the present invention;

[0039] Both ends of the headrest 104 are threaded with screws 106, and both screws 106 are rotatably connected with connecting plates 107. Both ends of the two connecting plates 107 are fixed with plugs 108, and the four plugs 108 are slidably connected in the four slots 105 respectively.

[0040] Under normal conditions, the inner surface of the plug 108 is coplanar with the arc-shaped surface of the top surface of the headrest 104, which can better support the head. At the same time, the four plugs 108 isolate the four slots 105 from the four vents 103 to prevent the head from getting cold.

[0041] When it is necessary to ventilate and cool the head, manually turn the screws 106 on both sides to move the two connecting plates 107 outward. The two connecting plates 107 move the corresponding plugs 108 outward, thereby exposing the four slots 105. The slots 105 are connected to the vents 103 to ventilate and cool the head.

[0042] See Figure 8 The diagram shows an embodiment of the present invention that improves the massage effect on the skin of the cervical spine.

[0043] The massage roller 403 has multiple rubber massage bumps formed on it, which can improve the massage effect on the skin of the cervical spine area.

[0044] Furthermore, both the headrest 104 and the cervical pillow 201 are bonded with a sponge layer; both the arc-shaped plate 303 and the plug 108 are bonded with a sponge layer; thus improving the comfort of the patient.

[0045] See Figure 1 A schematic diagram of an embodiment of the present invention, which facilitates the disassembly and replacement of the headrest 104 and cervical pillow 201, is shown.

[0046] The headrest 104 and cervical pillow 201 are detachably connected to the bed frame 101 and the mounting slot 102 by screws, respectively, which facilitates the removal and replacement of the headrest 104 and cervical pillow 201.

[0047] The electric linear actuator 206 is available in one model, JS-TGZ-U2, and other applicable models in the prior art can also be used.

[0048] The model numbers of motor II 402 and motor I 301 are provided as Z2-11 to 112, and other applicable models in the prior art can also be used.
