Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a cervical vertebra assisted treatment device for the pain department. Background Art

During the massage of the cervical vertebra, a cervical vertebra massager is mostly used for massage.
[0003] For example, Chinese Patent with the publication number of "CN110664600B" discloses "a cervical vertebra assisted treatment device for the pain department". Its main structure includes a nursing pillow main body, a motor and a massage ball; a group of the motors are fixedly connected inside the nursing pillow main body; a plurality of the steering brackets are axially connected inside the nursing pillow main body; a group of the intermediate transmission shafts are axially connected to the bottom of the steering brackets; two groups of the massage wheels are axially connected to the top of the steering brackets; a group of the adjusting rods are axially connected to the inner side of the lower part of the front end face of the nursing pillow main body. By changing the existing large massage wheel massage method to small massage wheel massage, this device can prevent secondary injuries caused by excessive force during massage, and the massage feeling is better.

During use, the installation angle of the massage wheel can be changed to achieve rolling massage in different directions, improve the massage effect, and realize massage and relaxation of muscles in different directions, so as to achieve the purpose of relieving pain.
[0004] However, in some patients, the bone mass at the cervical vertebra is relatively loose (such as the elderly group or people suffering from osteoporosis). When the above-mentioned cervical vertebra assisted treatment device for the pain department massages the cervical vertebra of the patient, since it uses the form of contact between the massage wheel and the patient's neck for massage treatment, the contact between the massage wheel and the bones at the cervical vertebra is a rigid structure, which is likely to cause secondary injury events caused by rigid contact, and there are relatively large potential safety hazards in use.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figure 1 and Figure 2 、 Figure 3 and Figure 4, A cervical spine assisted treatment device for the pain department, comprising a hollow pillow body 1 with bottom support legs 2 installed at the bottom, a driving motor 7 fixedly installed at the bottom of the hollow pillow body 1 through a motor fixed housing 6, a liquid storage cavity 3 arranged in the hollow pillow body 1, a rectangular notch 5 arranged at the top of the hollow pillow body 1, an elastic air film 4 sealingly embedded in the rectangular notch 5, a first rod body perforation 9 arranged on one side of the hollow pillow body 1, a reciprocating liquid compression mechanism 10 capable of generating axial reciprocating motion and driving the surrounding liquid, and a buffer liquid filled in the liquid storage cavity 3. And the amount of the buffer liquid is sufficient to make the elastic air film 4 in a flat state in the non-working state and capable of bulging upward during work. Fix the bottom support legs 2 at the head of the bed and make the height of the top of the hollow pillow body 1 conform to the height of the human headrest. Turn on the driving motor 7. Since the amount of the buffer liquid in the liquid storage cavity 3 of the hollow pillow body 1 is constantly changing, the elastic air film 4 generates a reciprocating elastic expansion phenomenon, thereby performing a flexible massage on the patient's neck. By controlling the rotation speed of the driving motor 7, the massage frequency can be controlled.
[0020] Regarding the specific structure of the reciprocating liquid compression mechanism 10, please refer to Figure 3 and Figure 4, including a first hollow cylinder 101. One end face of the first hollow cylinder 101 is provided with a first mounting plate 102 which is of an integral structure with it and fixedly installed on an inner vertical surface of the hollow pillow 1. Inside the first hollow cylinder 101, there is a first component activity cavity 103 with one end in an open state. The other end of the first hollow cylinder 101 is provided with a first liquid flow hole 104 communicating the external space and one end of the first component activity cavity 103. Inside the first hollow cylinder 101 and within the first component activity cavity 103, there is a first piston body 105 capable of moving axially along the first component activity cavity 103. One end of the first piston body 105 facing the open end of the first component activity cavity 103 is provided with a spherical cavity 106 with an inward concave structure. Inside the spherical cavity 106 of the first piston body 105, there is a rotatable rotating ball head 107. One side of the rotating ball head 107 is provided with a movable rod 108 of an integral structure with it. The end of the movable rod 108 is fixedly installed with a fixed sleeve 109. The structural radius of the spherical cavity 106 matches the structural radius of the rotating ball head 107, and the depth of the spherical cavity 106 is greater than the structural radius of the rotating ball head 107 and less than the structural diameter of the rotating ball head 107. According to the piston movement principle, under the action of the L-shaped solid shaft 118, the movable rod 108 will cause the first piston body 105 to continuously perform suction and discharge functions inside the first component activity cavity 103. When the buffer liquid in the liquid storage cavity 3 is sucked into the first component activity cavity 103, the liquid volume inside the liquid storage cavity 3 will decrease. At this time, the elastic air film 4 will reset downward. On the contrary, when the buffer liquid in the first component activity cavity 103 is discharged into the liquid storage cavity 3, the liquid volume inside the liquid storage cavity 3 will increase. At this time, the elastic air film 4 will expand upward to perform a flexible massage on the patient.
[0021] To achieve the adjustable function of the compression stroke and thus adjust the depth of a single massage, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6, an adjustable rotating mechanism 11 needs to be set up. Inside it, there is an L-shaped hollow shaft 112 that can rotate with the rotor 8 of the driving motor 7 and is hollow inside, an L-shaped solid shaft 118 that produces a horizontal movement effect under the combined action of liquid pressure and a spiral spring 119, and a fixed shaft structure 1110 arranged at the longitudinal end of the L-shaped solid shaft 118 and capable of driving the reciprocating liquid compression mechanism 10 to produce reciprocating motion. When the driving motor 7 is started, the rotor 8 will drive the L-shaped hollow shaft 112 to rotate, and then drive the second hollow sleeve 111 and the fixed shaft structure 1110 to produce a circular motion around the rotor 8. When the compensation liquid enters the second component activity cavity 113, it will exert a force on the second piston body 117, causing the second piston body 117 to move in a specific direction and making more of the L-shaped solid shaft 118 extend, thereby increasing the distance between the fixed shaft structure 1110 and the rotor 8, enabling the first piston body 105 to have a larger buffer liquid driving amount, and thus increasing the massage depth. Conversely, the massage depth will be reduced.
[0022] For the specific structure of the adjustable rotating mechanism 11, please refer to Figure 5 and Figure 6 , it also includes a second hollow sleeve 111 in a horizontal state. One end face of the second hollow sleeve 111 is provided with an L-shaped hollow shaft 112 integrally structured with it. Inside the second hollow sleeve 111, there is a second component activity cavity 113. Inside the second hollow sleeve 111, there is a second liquid flow hole 114 with one end communicating with one end of the second component activity cavity 113. At the longitudinal shaft body of the L-shaped hollow shaft 112, there is a third liquid flow hole 115 communicating with the external space and the second liquid flow hole 114. The other end of the second hollow sleeve 111 is provided with a second rod body perforation 116 communicating with the external space and the other end of the second component activity cavity 113. Inside the second hollow sleeve 111 and located inside the second component activity cavity 113, there is a second piston body 117 that can move axially along the second component activity cavity 113. One end of the second piston body 117 is fixedly installed with an L-shaped solid shaft 118 passing through the second rod body perforation 116. Around the shaft body of the L-shaped solid shaft 118 located inside the second component activity cavity 113, there is a compressed spiral spring 119 sleeved. At the longitudinal shaft body end of the L-shaped solid shaft 118, there is a fixed shaft structure 1110 integrally structured with it. The shaft body of the fixed shaft structure 1110 is installed in the sleeve hole of the fixed sleeve 109 through a bearing. The elastic pressure generated by the spiral spring 119 on the second piston body 117 is sufficient to keep the second piston body 117 stationary during operation. The structural shape of the cross-section of the second rod body perforation 116 is the same as that of the cross-section of the L-shaped solid shaft 118, both being polygonal structures, and the structural dimensions of the cross-section of the second rod body perforation 116 match the structural dimensions of the cross-section of the L-shaped solid shaft 118.
[0023] In order to achieve the directional movement of the compensation liquid and the compensation function for the capacity inside the liquid storage cavity 3, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 . It is necessary to set up a hydraulic drive type space compensation mechanism 12, which is internally provided with a hollow ring body 129 installed in a rotatable form around the L-shaped hollow shaft 112 and in a hollow state inside, and a third piston body 127 that can make the compensation liquid flow relative to the hollow ring body 129 during horizontal movement. By pushing and pulling the horizontal push rod 128, the third piston body 127 can generate a directional movement inside the third component activity cavity 123, so that the compensation liquid located inside the third component activity cavity 123 changes. The compensation liquid will move inside the third liquid flow hole 115 through the annular liquid flow cavity 1210, thereby achieving the directional movement of the compensation liquid. At this time, since the position of the third piston body 127 inside the third component activity cavity 123 changes, the space directly communicating with the liquid storage cavity 3 will change to cope with the corresponding changes in the compression stroke of the first piston body 105. The changes between the two will act together on the bottom surface of the elastic air film 4, so that the elastic air film 4 can change the massage depth. It should be noted that the massage depth refers to the height change of the elastic air film 4 before and after being subjected to the buffer liquid pressure and not being subjected to the buffer liquid pressure.
[0024] Regarding the specific structure of the hydraulic drive type space compensation mechanism 12, please refer to Figure 5 and Figure 6, further comprising a third hollow cylinder body 121. One end of the third hollow cylinder body 121 is provided with a second mounting plate 122 which is of an integral structure with it and fixedly installed inside the hollow pillow body 1. Inside the third hollow cylinder body 121, there is a third component activity cavity 123 with one end being in an open state. One end of the third component activity cavity 123 is provided with a liquid reserve cavity 124. The center of the second mounting plate 122 is provided with a third rod body through hole 125 that communicates the first rod body through hole 9 and the liquid reserve cavity 124. Inside the third hollow cylinder body 121 and within the third component activity cavity 123, there is placed a third piston body 127 capable of moving axially along the third component activity cavity 123. One end of the third piston body 127 is fixedly installed with a horizontal push rod 128 that penetrates through the liquid reserve cavity 124 and the third rod body through hole 125. Inside the third hollow cylinder body 121 and within the third rod body through hole 125, there is installed a rubber braking ring 126 capable of braking the horizontal push rod 128. Inside the hollow ring body 129, there is an annular liquid flow cavity 1210. Both ends of the hollow ring body 129 are provided with shaft body mounting holes 1211 that can be installed on the shaft body of the L-shaped hollow shaft 112 through bearings and sealing rings, and one end of the third liquid flow hole 115 communicates with the annular liquid flow cavity 1210. The annular liquid flow cavity 1210 and the liquid reserve cavity 124 are communicated through a connecting pipe 1212. The closed area formed by the third component activity cavity 123, the third piston body 127, the connecting pipe 1212, the annular liquid flow cavity 1210, the third liquid flow hole 115, the second liquid flow hole 114, the second component activity cavity 113, and the second piston body 117 is filled with a compensating liquid. The braking intensity formed by the rubber braking ring 126 on the horizontal push rod 128 is sufficient to keep the horizontal push rod 128 stationary during operation.
[0025] During use, fixedly install the bottom support legs 2 at the head of the bed, and make the height of the top of the hollow pillow body 1 conform to the height of a human headrest. Turn on the drive motor 7. Since the amount of the buffer liquid in the liquid storage cavity 3 of the hollow pillow body 1 constantly changes, the elastic air film 4 generates a reciprocating elastic expansion phenomenon, thereby performing a flexible massage on the patient's neck. By controlling the rotation speed of the drive motor 7, the massage frequency can be controlled.
