Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a decompression device for preventing occipital pressure sores by skull traction. Background Art
[0002] In the clinical treatment of neurosurgery and spinal surgery, skull traction is a commonly used treatment method. However, long-term skull traction can cause excessive pressure in the contact area between the patient's head and the occipital region, which in turn causes occipital pressure sores, causing additional pain and inconvenience to the patient. Although there are some decompression devices on the market, they are generally circular cushions with a hollow structure in the middle. The structure is relatively simple and can only decompress specific points. The decompression effect is poor, and the height cannot be adjusted according to the patient, resulting in low applicability. Therefore, in response to the above problems, the present invention proposes a new type of skull traction decompression device for preventing occipital pressure sores. Utility Model Content

[0004] In order to solve the above problems, the technical solution adopted by the utility model is a decompression device for skull traction to prevent occipital pressure sores, including a base, a decompression structure is provided above the base, an adjustable structure is provided between the decompression structure and the base, the decompression structure includes a connecting plate, a decompression pad is fixed on the upper side of the connecting plate, and several air bags are fixed around the outside of the decompression pad. The adjustable structure includes a connecting platform fixed on the upper side of the base, an opening is provided on the upper side of the connecting platform, a gear is rotatably provided on the inside of the opening, a worm gear is fixed on one side of the gear through the connecting platform, two limit plates are fixed on one side of the connecting platform, a worm is rotatably provided below the worm gear between the two limit plates, and a rack rod meshing with the gear is fixed in the opening on the lower side of the connecting plate.
[0005] As a further solution of the present invention: there are eight airbags in total, namely airbag one, airbag two, airbag three, airbag four, airbag five, airbag six, airbag seven, and airbag eight, among which airbag one and airbag eight are connected to the side with inflation ports, and airbag one, airbag three, airbag five, and airbag seven are connected to each other, and airbag two, airbag four, airbag six, and airbag eight are connected to each other. When airbag one, airbag three, airbag five, and airbag seven are deflated, airbag two, airbag four, airbag six, and airbag eight are decompression points, and vice versa.
[0006] As a further solution of the present invention: the length of the rack rod is equal to the depth of the opening.
[0007] As a further solution of the present invention: the worm and the worm wheel are meshed with each other, and rotating the worm can drive the worm wheel to rotate, and then drive the gear to rotate.
[0008] As a further solution of the present invention: a rotating shaft is fixed to one side of the worm, and a handle is fixed to one end of the rotating shaft to facilitate the rotation of the worm.
[0009] As a further solution of the present invention: the eight air bags are all equal in size.
[0010] Compared with the existing technology, the advantages of the present invention are: this patent adds a decompression structure, which consists of eight airbags and a decompression pad. When the airbag is not inflated, the decompression pad is the decompression point. When airbag one, airbag three, airbag five, and airbag seven are inflated, the other airbags are decompression points, and vice versa; an adjustable structure is added, which can adjust the height of the decompression structure to adapt to different patients.
