DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1-Figure 4 A nursing device for treating migraine is shown, comprising a flat side adjustment seat 201, a bracket mechanism for supporting the flat side adjustment seat 201, and a massage mechanism. An adjustment ring 202 rotatably connected to the flat side adjustment seat 201 is movably sleeved on the outer wall of the flat side adjustment seat 201. A pair of anti-slip clamping plates 203 are fixedly installed on the outer wall of the flat side adjustment seat 201. The pair of anti-slip clamping plates 203 are respectively located on both sides of the adjustment ring 202. Adjustment contact electric push rods 301 are arranged on both sides of the flat side adjustment seat 201. The output end of the adjustment contact electric push rod 301 is fixedly connected to the support plate 302. One of the adjustment contact electric push rods 301 is fixedly connected to the adjustment ring 202 through a movable connecting rod 204, and the other adjustment contact electric push rod 301 is fixedly connected to the flat side adjustment seat 201 through a fixed connecting rod 205. The massage mechanism includes two massage components for massaging the temples, and the two massage components are respectively arranged on two support plates 302. The massage mechanism has two operating modes: a double-sided massage mode and a single-sided massage mode. In the double-sided massage mode, the two massage components work simultaneously. In the single-sided massage mode, one of the massage components is selectively started. The massage components in this embodiment adopt existing technologies.

[0021] When in use, the electric push rod 301 can be controlled to push the support plate 302 for adjustment until the space between the two support plates 302 can fully accommodate the patient's head. Then the patient can lie flat on the bed with the head between the two support plates 302, and then the electric push rod 301 can be controlled to pull the support plate 302 for adjustment until the massage component is in contact with the patient's temple. Then the massage mechanism can be started to massage the patient's temple. The operation mode of the massage mechanism can be reasonably selected according to the patient's needs. If the patient needs to massage the temples on both sides at the same time, the bilateral massage mode can be selected, and the two massage components will massage the temples on both sides of the patient respectively. If the patient only needs to massage one side of the temple, the unilateral massage mode can be selected, and it can be set whether to start the massage component on the left side or the massage component on the right side. Then, according to the setting, the massage component on the corresponding side will massage the temple on the corresponding side of the patient. Since one of the adjusting electric push rods 301 is fixedly connected to the adjusting ring 202 through the movable connecting rod 204, and the adjusting ring 202 can rotate along the flat side adjusting seat 201, the corresponding massage component can be rotated and adjusted (rotated and adjusted with the flat side adjusting seat 201 as the central axis). For the convenience of description, this massage component is assumed to be A. For patients who like to lie on their side, especially patients with unilateral migraine who like to lie on their side, the patient can lie on his side on the bed, and then rotate the adjusting ring 202 to rotate and adjust A until A is rotated to the top of the patient's head and aligned with the patient's temple, and then control the corresponding adjusting electric push rod 301 to push the corresponding support plate 302 until A is in contact with the patient's temple, and then select the unilateral massage mode and set to start A, so that the patient's temple can be massaged when the patient lies on his side. In addition, when the patient lies on his side, the head may be in a tilted state. When adjusting A, A can be made to be in a corresponding tilted state so that A can fit the patient's temple; Therefore, through the combined arrangement of the flat side adjustment seat 201, the adjustment ring 202, etc., when using the care device in the present application, the patient only needs to lie between the two massage components, without having to wear the device on the head, which is less likely to cause discomfort to the patient and neck fatigue. The patient can use it while lying flat or lying on his side, which can greatly improve the patient's comfort when using it.

[0022] The bracket mechanism includes a base 101, a vertical cylinder 102 is fixedly installed on the top of the base 101, a lifting electric push rod 103 is fixedly installed in the vertical cylinder 102, and a lifting slide bar 104 is fixedly connected to the output end of the lifting electric push rod 103. The lifting slide bar 104 penetrates the top outer wall of the vertical cylinder 102 and extends to the outside of the vertical cylinder 102, and the lifting slide bar 104 is slidably connected to the top outer wall of the vertical cylinder 102. A linkage rod 105 is fixedly connected between the lifting slide bar 104 and the flat side adjustment seat 201. The base 101 is located on the left or right side of the flat side adjustment seat 201, the linkage rod 105 is set to an L shape, and a plurality of universal wheels are set at the bottom end of the base 101.

[0023] Taking into account that a bed generally has a headboard, and the headboard is generally against a wall, the bracket mechanism is designed so that when the nursing device is used, the base 101 can be located on one side of the bed, and under the action of the linkage rod 105, the flat side adjustment seat 201 can be extended to the top of the bed, so that the patient can directly lie on the bed and use the nursing device in this application without moving or adjusting the bed. In addition, the lifting electric push rod 103 is controlled to drive the lifting slide bar 104 to move up and down, which can drive the flat side adjustment seat 201 to move up and down, and then the massage mechanism can move up and down. Therefore, through the setting of the bracket mechanism, the nursing device can be raised and lowered according to the height of the bed, and the patient can directly lie on the bed to use the nursing device without moving or adjusting the bed specifically to accommodate the nursing device, thereby improving practicality.

[0024] The second implementation method: Figure 5-Figure 8 A nursing device for treating migraine is shown. Different from the first embodiment, the flat side adjustment seat 201 is a sealed cylindrical structure. A reinforced electric push rod 206 is fixedly installed in the flat side adjustment seat 201. The output end of the reinforced electric push rod 206 is fixedly connected to a reinforced piston plate 207 which is slidingly and sealedly connected to the inner wall of the flat side adjustment seat 201. A plurality of reinforced adjustment holes 208 are opened on the outer wall of the flat side adjustment seat 201. A reinforced elastic membrane 209 matching it is sealed and fixedly installed in each reinforced adjustment hole 208. The reinforced adjustment hole 208 is located on the inner side of the adjustment ring 202, and the reinforced adjustment hole 208 is located on the side of the reinforced piston plate 207 away from the reinforced electric push rod 206.

[0025] After A is adjusted according to the patient's needs, the reinforced electric push rod 206 can be controlled to push the reinforced piston plate 207, so that the air pressure on the side of the reinforced piston plate 207 close to the reinforced elastic membrane 209 increases. The increase in air pressure will cause the reinforced elastic membrane 209 to bulge outward and deform until it is against the inner wall of the adjustment ring 202, so that the adjustment ring 202 can be fixed by the friction force between the reinforced elastic membrane 209 and the adjustment ring 202 to prevent the adjustment ring 202 from rotating accidentally. Therefore, through the joint arrangement of the reinforced piston plate 207, the reinforced elastic membrane 209, etc., after the massage component is adjusted, the adjustment ring 202 can be effectively fixed to avoid displacement of the massage component, thereby improving the reliability of the nursing device.

[0026] The massage assembly includes a sealing cylinder 401 and a support tube 402 fixedly mounted on the support plate 302, the sealing cylinder 401 is located on the side of the support plate 302 away from the flat side adjustment seat 201, and the support tube 402 is located on the side of the support plate 302 close to the flat side adjustment seat 201, a driving electric push rod 403 is fixedly mounted in the sealing cylinder 401, and the output end of the driving electric push rod 403 is fixedly connected to a driving piston plate 404 that is slidingly sealed and connected to the inner wall of the sealing cylinder 401, an air guide tube 405 is connected between the sealing cylinder 401 and the support tube 402, and the support tube 402 The inner side of one end away from the support plate 302 is sealed and fixedly connected with a matching massage elastic diaphragm 409, the air guide tube 405 is located on the side of the driving piston plate 404 away from the driving electric push rod 403, and the air guide tube 405 passes through the support plate 302 and is fixedly connected thereto, the end of the support tube 402 away from the support plate 302 is sleeved with a matching limit surface sleeve 406, the limit surface sleeve 406 is threadedly connected to the support tube 402, a convex through hole 407 is opened in the middle of the limit surface sleeve 406, and the limit surface sleeve 406 is arranged with a variety of specifications according to the aperture of the convex through hole 407.

[0027] The electric push rod 403 is controlled to push and pull the piston plate 404 back and forth. When the electric push rod 403 pushes the piston plate 404, the air pressure on the side of the piston plate 404 close to the airway 405 will increase. The increase in air pressure will cause the massage elastic diaphragm 409 to bulge outward and deform, thereby squeezing the patient's temples, thereby achieving a massage effect. By adjusting the length of the stroke of the electric push rod 403 pushing the piston plate 404, the degree of outward bulging and deformation of the massage elastic diaphragm 409 can be adjusted, thereby adjusting the massage intensity. The limit cover 406 and the convex perforation 407 can adjust the massage elastic diaphragm 409. The convex deformation of the diaphragm 409 plays a limiting role. The larger the aperture of the convex perforation 407, the larger the contact area between the massage elastic diaphragm 409 and the patient's head after the convex deformation, and the larger the massage area. Therefore, the massage area can be adjusted by replacing the limit cover 406 of different specifications. Therefore, through the setting of the massage component, the massage component can massage the patient's temple by air pressure massage, which is not only comfortable but also safe and reliable. In addition, not only the massage intensity can be adjusted, but also the massage area can be adjusted, which further improves the practicality and comfort of the nursing device.

[0028] One end of the limiting sleeve 406 away from the support tube 402 is fixedly connected with a matching flexible annular pad 408 , the inner diameter of the flexible annular pad 408 is the same as the aperture of the convex through hole 407 , and the flexible annular pad 408 can improve the comfort of the patient when using the nursing device.

[0029] It should be noted that the nursing device in the present application is also equipped with a controller and a control system, which are used to control, set and adjust the nursing device. The controller and the control system are prior art and will not be described in detail here.

[0030] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
