During the rotation process, the inflatable ball can perform circular massage on the patient's waist, which can relieve the patient's waist fatigue, increase the patient's comfort, and help improve the blood circulation of the waist muscles and the repair and rehabilitation of the patient's lumbar vertebra;

[0026] When it is necessary to change the soft or hard state of the inflatable ball, when the gas enters the L-shaped channel through the transverse channel, the gas can push the top column to move outward, and the second spring is stretched. When one end of the L-shaped through hole leaves the L-shaped channel, the gas can enter the inflatable ball through the L-shaped through hole, and the top column presses against the inner wall of the inflatable ball. At this time, the two middle inflatable balls feel hard, and the inflatable balls on both sides feel soft. When the round block rotates, it can drive the four inflatable balls to rotate at the same time. The hard inflatable ball and the soft inflatable ball massage the patient's lumbar vertebrae, which can have different massage effects, thereby improving the patient's comfort.

[0050] When the patient's lumbar spine needs to be cared for, the patient sits on the nursing cushion 101, and the adaptation component fills the distance and gap between the patient's waist and the chair back to provide support for the patient's waist, so that the massage component fits the patient's waist. Subsequently, the massage component is inflated by the inflation component, so that the massage component can gently massage the patient's waist. During the massage process, the massage component can change its different soft or hard states through the cooperation of the deflation component and the pushing component, so that the massage component can effectively massage the patient's lumbar spine, which not only improves the use effect of the device and the comfort of the patient, but also reduces the burden on the patient's lumbar spine.

[0051] like Figure 3As shown, the adaptable component includes an airbag 201, the airbag 201 is fixedly connected to the inner wall of the rectangular shell 103, the bottom end of the rectangular shell 103 is fixedly connected to an inflatable device 202, the rear end of the inflatable device 202 is fixedly connected to a first inflatable tube 203, one end of the first inflatable tube 203 is fixedly connected to the rear end of the airbag 201, the first inflatable tube 203 runs through the rear end of the rectangular shell 103, the front end of the airbag 201 is fixedly connected to a rectangular plate 204, and the rectangular plate 204 is slidably connected to the rear end of the airbag 201. On the inner wall of the rectangular shell 103, the rear end of the airbag 201 is fixedly connected with an air outlet pipe 235, and the air outlet pipe 235 passes through the rear end of the rectangular shell 103, wherein the sliding direction of the rectangular plate 204 is close to the lumbar vertebrae direction and the principle lumbar vertebrae direction, that is, it slides along the opening direction of the rectangular shell 103. The method for realizing the sliding of the rectangular plate 204 in the rectangular shell 103 can be to open a guide slide rail on the inner wall of the rectangular shell 103 along the sliding direction or to set a sliding roller or a combination of the two methods, or other implementation methods can be used.

[0052] When the patient's waist needs to adapt to the chair back, the inflation device 202 is started. The inflation device 202 inflates the air bag 201 through the first inflation tube 203. The expansion of the air bag 201 pushes the rectangular plate 204 to move, so that the rectangular plate 204 fills the distance and gap between the patient's waist and the chair back, providing support for the patient's waist. The air bag 201 can be inflated and adjusted according to the body shape, sitting habits and waist needs of different patients, which can better fit the patient's waist, provide stable and comfortable support effect, and prevent the waist from being suspended and unevenly stressed due to excessive gaps.

[0053] like Figure 3 As shown, the reset assembly includes a positioning plate 205, which is fixedly connected to the rear end of the rectangular shell 103, and the rear end of the rectangular shell 103 is slidably connected to a sliding plate 206. Two first springs 207 are fixedly connected between the bottom end of the sliding plate 206 and the positioning plate 205. The first springs 207 are in a compressed state. The top of the sliding plate 206 is symmetrically fixedly connected to a connecting rope 208. One end of the two connecting ropes 208 is fixedly connected to the rear end of the rectangular plate 204, and the connecting rope 208 slides through the rear end of the rectangular shell 103.

[0054] When the rectangular plate 204 needs to be reset, when the rectangular plate 204 moves outward, the rectangular plate 204 can drive the connecting rope 208 to slide, the connecting rope 208 drives the sliding plate 206 to move upward, and the first spring 207 is stretched. When the device is used up, the inflation device 202 is closed, and the air in the airbag 201 is discharged through the exhaust pipe 235. The first spring 207 rebounds, and the sliding plate 206 drives the connecting rope 208 to slide toward the positioning plate 205. The connecting rope 208 drives the rectangular plate 204 to reset, so that the device can be used next time.

[0055] like Figure 4 、 Figure 5 and Figure 6 As shown, the massage component includes three rotating shafts 209, and the three rotating shafts 209 are rotatably connected to the front end of the rectangular plate 204. The front ends of the three rotating shafts 209 are fixedly connected with a round block 210, and the front ends of the round blocks 210 are fixedly connected with an inflatable ball 211. The front end of the rectangular plate 204 is fixedly connected with a fixed plate 212, and the bottom end of the fixed plate 212 is fixedly connected with a motor 213. The output end of the motor 213 is fixedly connected with a rotating rod 214, and the bottom end of the rotating rod 214 is fixedly connected with a first bevel gear 215. The outer surface of one of the rotating shafts 209 is fixedly connected with a second bevel gear 216, and the second bevel gear 216 is meshed with the first bevel gear 215. The outer surfaces of the three rotating shafts 209 are fixedly connected with pulleys 217, and a transmission belt 218 is arranged between the three pulleys 217.

[0056] When the patient's waist needs to be massaged, the inflatable ball 211 is inflated through the inflation component, and then the motor 213 is started. The output end of the motor 213 drives the rotating rod 214 to rotate back and forth, and the rotating rod 214 drives the first bevel gear 215 to rotate. The first bevel gear 215 drives the second bevel gear 216 and one of the rotating shafts 209 to rotate. The rotating shaft 209 drives one of the pulleys 217 to rotate. Through the action of the transmission belt 218, the other two rotating shafts 209 can be driven to rotate at the same time. While rotating, the rotating shaft 209 drives the round block 210 and the inflatable ball 211 to rotate back and forth. During the rotation process, the inflatable ball 211 can perform a circular massage on the patient's waist, which can relieve the patient's waist fatigue, increase the patient's comfort, and help improve the blood circulation of the waist muscles and the repair and rehabilitation of the patient's lumbar spine.

[0057] like Figure 7 and Figure 8As shown, the inflatable component includes four L-shaped channels 219, and the four L-shaped channels 219 are all opened on the round block 210. A transverse channel 220 is opened in the middle of the round block 210, and the transverse channel 220 is connected to the four L-shaped channels 219. The middle parts of the three round blocks 210 are fixedly connected with connecting pipes 221, and the three connecting pipes 221 are connected to the corresponding transverse channels 220. The top ends of the three connecting pipes 221 are fixedly connected with the same hose 222, and the hose 222 is connected to the connecting pipe 221. A second inflatable pipe 223 is fixedly connected to the hose 222, and one end of the second inflatable pipe 223 is fixedly connected to the first inflatable pipe 203. The second inflatable pipe 223 passes through the rectangular plate 204 and the rectangular shell 103, and the L-shaped channel 219 is connected to the inflatable ball 211. Each L-shaped channel is connected to an inflatable ball 211.

[0058] Among them, such as Figure 7 As shown, the specific structure of the L channel is: two channels vertically connected in two spaces are connected and arranged on the circular block 210, one of the channels is arranged along the thickness direction of the circular block (perpendicular to the plane of the circular block surface), and the other channel is arranged parallel to the plane where the circular block surface is located.

[0059] The number of the inflatable balls 211 on each round block 210 is equal to the number of the L-shaped channels.

[0060] When the inflatable ball 211 needs to be inflated, the inflatable device 202 is started, and the gas enters the second inflatable tube 223 through the first inflatable tube 203, enters the hose 222 and the three connecting tubes 221 through the second inflatable tube 223, and then enters the transverse channel 220 and the four L-shaped channels 219 through the connecting tube 221. The inflatable ball 211 is inflated through the L-shaped channel 219 to expand the inflatable ball 211, which facilitates the massage component to massage the patient's waist and improve the repair and rehabilitation of the patient's lumbar spine. During the rotation of the round block 210, since it rotates back and forth, the relevant pipelines will not produce motion interference.

[0061] like Figure 9 As shown, the inner walls of the two middle L-shaped channels 219 are slidably connected with a top column 224, and a second spring 225 is fixedly connected between the inner wall of the L-shaped channel 219 and the top column 224. A plurality of L-shaped through holes 226 are opened on the top column 224, and the plurality of L-shaped through holes 226 are arranged in a circle.

[0062] When the patient's waist needs to be massaged, when the gas enters the L-shaped channel 219 through the transverse channel 220, the gas can push the top column 224 to move outward, and the second spring 225 is stretched. When one end of the L-shaped through hole 226 leaves the L-shaped channel 219, that is, the L-shaped channel 219 is connected to the inflatable ball 211 through the L-shaped through hole 226, the gas can enter the inflatable ball 211 through the L-shaped through hole 226, and the top column 224 presses against the inner wall of the inflatable ball 211, and the inflatable ball 211 is fully The diameter after expansion is smaller than the length of the top column 224. At this time, the two middle inflatable balls 211 feel hard, that is, during massage, the top column 224 directly presses against the patient's waist, which has different massage effects. The inflatable balls 211 on both sides feel soft. When the round block 210 rotates, it can drive the four inflatable balls 211 to rotate at the same time. The hard inflatable balls 211 and the soft inflatable balls 211 massage the patient's lumbar spine, which can have different massage effects, thereby improving the patient's comfort.

[0063] like Figure 10 and Figure 11 As shown, the deflation component includes two deflation pipes 227, which are fixedly connected to the two outer inflatable balls 211. The inner wall of the deflation pipe 227 is fixedly connected with a circular plate 228, and a circular hole 229 is opened in the middle of the circular plate 228. A sealing ball 230 is engaged with the inner wall of the circular hole 229, and two elastic ropes 231 are fixedly connected between the inner wall of the deflation pipe 227 and the sealing ball 230.

[0064] When the gas in the inflatable ball 211 needs to be released, the sealing ball 230 is pushed by the pushing assembly, and the sealing ball 230 is pushed out of the circular hole 229 on the circular plate 228, and the elastic rope 231 is stretched. When the sealing ball 230 leaves the circular hole 229, the gas in the inflatable ball 211 is discharged through the gap between the sealing ball 230 and the circular hole 229, and the gas in the inflatable ball 211 is released. After the release is completed, the elastic rope 231 rebounds, driving the sealing ball 230 to engage in the circular hole 229, and the deflation pipe 227 is sealed. By continuously deflating and inflating the inflatable ball 211, the two inflatable balls 211 on both sides can be changed to different hardness and softness states, and the inflatable ball 211 in the middle does not need to change its state.

[0065] like Figure 5 and Figure 10 As shown, the pushing assembly includes a connecting rod 232, which is fixedly connected to the outer surface of the sealing ball 230. The end of the connecting rod 232 away from the sealing ball 230 is fixedly connected to the ball 233. The front end of the rectangular plate 204 is fixedly connected to three arc-shaped plates 234 located below the round block 210. The arc-shaped plates 234 are located on the trajectory of the round block 233 rotating around the center of the round block 210.

[0066] When it is necessary to push the sealing ball 230, the two outer inflatable balls 211 drive the deflation pipe 227 to rotate during the reciprocating rotation. When the ball 233 rotates to contact the arc plate 234, the arc plate 234 can force the ball 233 to move, and the ball 233 drives the connecting rod 232 to move. The connecting rod 232 drives the sealing ball 230 to be pushed out from the circular hole 229 on the circular plate 228 to release the gas in the inflatable ball 211. When the ball 233 leaves the arc plate 234, it rebounds through the elastic rope 231, and the sealing ball 230 is engaged in the circular hole 229 to seal the deflation pipe 227.

[0067] like Figure 12 As shown, the inner wall of the air outlet pipe 235 is rotatably connected to a sealing plate 236, the outer surface of the sealing plate 236 is fixedly connected to a connecting shaft 237, the inner wall of the air outlet pipe 235 is fixedly connected to a rubber ring 238, the connecting shaft 237 is rotatably connected in the rubber ring 238, and one end of the connecting shaft 237 is fixedly connected to a rotating block 239.

[0068] When the airbag 201 needs to be deflated, the rotating block 239 is rotated, and the rotating block 239 drives the connecting shaft 237 to rotate, and the connecting shaft 237 drives the sealing plate 236 to rotate, rotating the sealing plate 236 from a vertical state to a horizontal state, and the air outlet pipe 235 is opened. The gas in the airbag 201 is discharged through the gap between the sealing plate 236 and the air outlet pipe 235.

[0069] like Figure 3 and Figure 13 As shown, two T-shaped sliding blocks 240 are fixedly connected to the front end of the sliding plate 206 symmetrically, and two T-shaped sliding grooves 241 that cooperate with the T-shaped sliding blocks 240 are formed at the rear end of the rectangular shell 103.

[0070] By providing a T-shaped slider 240 and a T-shaped slot 241, when the sliding plate 206 is moving, the sliding plate 206 will drive the T-shaped slider 240 to slide in the T-shaped slot 241. The T-shaped slot 241 can limit and guide the T-shaped slider 240 and the sliding plate 206, making the sliding plate 206 more stable during movement.

[0071] Among them, the T-shaped slider is set as an integral whole, one end of the longitudinal block of the T-shaped slider is fixed on the sliding plate, and a horizontal block is set at the other end of the longitudinal block of the T-shaped slider. The horizontal block is set perpendicular to the longitudinal block, and the horizontal block is inserted into the T-shaped slide groove and supported to move up and down in the T-shaped slide groove.

[0072] In a second aspect, the present invention provides a method for using a medical lumbar vertebra care device, which is applied to the above-mentioned medical lumbar vertebra care device, and the method comprises:

[0073] S1. Inflate the airbag using an inflation device to cause the rectangular plate to slide from an original position to abut against a target position within the rectangular shell;

[0074] S2, drive the massage component to massage the target position,

[0075] Wherein, when the target position is massaged, the massage intensity is adjusted by the deflation component and the pushing component;

[0076] S3. When the massage is finished, the gas in the medical lumbar vertebra care device is discharged through the deflation component, the gas in the airbag is eliminated, and the reset component drives the rectangular plate to reset to its original position.

[0077] When the method of the present invention is actually applied, the specific steps include:

[0078] The patient sits on the nursing cushion 101, and then rotates the rotating block 239, which drives the connecting shaft 237 to rotate, and the connecting shaft 237 drives the sealing plate 236 to rotate, and rotates the sealing plate 236 to a vertical state, so that the air outlet pipe 235 is sealed, and the inflation device 202 is started. The inflation device 202 inflates the air bag 201 through the first inflation tube 203. The expansion of the air bag 201 pushes the rectangular plate 204 to move, so that the rectangular plate 204 fills the distance and gap between the patient's waist and the chair back, providing support for the patient's waist. When the rectangular plate 204 moves outward, the rectangular plate 204 can drive the connecting rope 208 to slide, and the connecting rope 208 drives the sliding plate 206 to move upward, and the first spring 207 is stretched. Then, when the inflation device 202 inflates the airbag 201, the gas enters the second inflation tube 223 through the first inflation tube 203, enters the hose 222 and the three connecting tubes 221 through the second inflation tube 223, and then enters the transverse channel 220 and the four L-shaped channels 219 through the connecting tube 221. The inflation ball 211 is inflated through the L-shaped channel 219, so that the inflation ball 211 expands and contacts the patient's lumbar vertebra. Subsequently, the motor 213 is started, and the output end of the motor 213 drives the rotating rod 214 to rotate reciprocatingly. The rotating rod 214 drives the first bevel gear 215 to rotate, and the first bevel gear 215 drives the second bevel gear 216 and one of the rotating shafts 209 to rotate, and the rotating shaft 209 drives one of the pulleys 217 to rotate. , through the action of the transmission belt 218, the other two rotating shafts 209 can be driven to rotate at the same time. While the rotating shaft 209 is rotating, it drives the round block 210 and the inflatable ball 211 to rotate back and forth. The inflatable ball 211 can perform a circular massage on the patient's waist during the rotation. When the gas enters the L-shaped channel 219 through the transverse channel 220, the gas can push the top column 224 to move outward, and the second spring 225 is stretched. When one end of the L-shaped through hole 226 leaves the L-shaped through hole 219, the gas can enter the inflatable ball 211 through the L-shaped through hole 226, and the top column 224 presses against the inner wall of the inflatable ball 211. At this time, the touch of the two middle inflatable balls 211 is hard, and the touch of the inflatable balls 211 on both sides is soft. When the round block 210 rotates, it can drive the four inflatable balls 211 to rotate simultaneously. The hard inflatable ball 211 and the soft inflatable ball 211 massage the patient's lumbar spine, achieving different massage effects, thereby improving the patient's comfort. When the three round blocks 210 are in the reciprocating rotation process, the two inflatable balls 211 on the outer sides of the three round blocks 210 respectively drive the deflation tube 227 to rotate. When the round ball 233 rotates to contact the arc plate 234, the arc plate 234 can press the round ball 233 to move. The round ball 233 drives the connecting rod 232 to move. The connecting rod 232 pushes the sealing ball 230 and pushes the sealing ball 230 out of the circular hole 229 on the circular plate 228. The elastic rope 231 is stretched. When the sealing ball 230 leaves the circular hole 229,The gas in the inflatable ball 211 is discharged through the gap between the sealing ball 230 and the circular hole 229, releasing the gas in the inflatable ball 211. When the ball 233 completely leaves the arc plate 234, the elastic rope 231 rebounds, driving the sealing ball 230 to engage with the circular hole 229, sealing the deflation pipe 227. Through the continuous reciprocating rotation of the round block 210, the two inflatable balls 211 in the middle are continuously deflated and inflated, changing different hard and soft states to massage the patient's lumbar spine. When the device is used, the rotating block 239 is rotated. 239 drives the connecting shaft 237 to rotate, and the connecting shaft 237 drives the sealing plate 236 to rotate, rotating the sealing plate 236 from a vertical position to a horizontal position. The outlet pipe 235 is opened, and the gas in the airbag 201 is discharged through the gap between the sealing plate 236 and the outlet pipe 235. The inflator 202 is closed, and the air in the airbag 201 is discharged through the outlet pipe 235. The first spring 207 rebounds, and the sliding plate 206 drives the connecting rope 208 to slide toward the positioning plate 205. The connecting rope 208 drives the rectangular plate 204 to return to its original position, making it easier to use the device next time.

[0079] In the above scheme, through the cooperation of the deflation component and the pushing component, the different soft or hard states of the massage component can be transformed, so that the massage component can effectively massage the patient's lumbar spine, which not only improves the use effect of the device and the comfort of the patient, but also reduces the burden on the patient's lumbar spine.

[0080] The present invention can inflate and adjust the airbag according to the body shape, sitting habits and waist needs of different patients, so as to better fit the patient's waist, provide a stable and comfortable support effect, and prevent the waist from being suspended and unevenly stressed due to excessive gaps.

[0081] The inflatable ball of the present invention can perform circular massage on the patient's waist during the rotation process, which can relieve the patient's waist fatigue, increase the patient's comfort, and help improve the blood circulation of the waist muscles and the repair and rehabilitation of the patient's lumbar spine.

[0082] Since the present invention supports changing the soft or hard state of the inflatable ball, and the hard inflatable ball and the soft inflatable ball massage the patient's lumbar spine to achieve different massage effects, the present invention improves the patient's comfort.
