Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a spinal activity assistor suitable for patients with ankylosing spondylitis. Background Art

[0002] Ankylosing spondylitis is a chronic inflammatory disease, mainly manifested as inflammation of the sacroiliac joints and spinal attachment points, as well as fibrosis and ossification of the large joints of the extremities, the fibrous ring of the intervertebral disc, and the connective tissue nearby. This can lead to symptoms such as limited spinal movement, low back pain, morning stiffness, and pain in the peripheral joints. As the disease progresses, the range of motion of the spine, such as forward flexion, backward extension, and lateral bending, gradually decreases, seriously affecting the quality of life of patients.

[0003] The treatment of ankylosing spondylitis mainly includes drug treatment, physical therapy, and rehabilitation training, etc. However, these treatment methods have certain limitations in improving spinal mobility.

[0004] Although drug treatment can relieve symptoms, it cannot fundamentally solve the problem of limited spinal movement. Drug treatment mainly involves anti-inflammatory and analgesic drugs, such as topical ibuprofen powder, diclofenac sodium powder, etc.

[0005] Physical therapies such as massage and acupuncture, although helpful in relieving muscle tension and pain, have limited effects and require long-term persistence. Rehabilitation training such as spinal stretching exercises, although helpful in improving spinal mobility, is difficult for patients with severe conditions to perform on their own.

[0006] The patent with the publication number CN114796744A discloses an ankylosing spondylitis spraying and massaging device, including a chair and a vertical groove provided on the chair. An outer shell is provided in the vertical groove, and a conduit is rotatably connected inside the outer shell; when in use, a syringe is used to inject warm water into a plurality of water sacs, and then the patient sits on the chair and presses the back against the backrest; then the height of the outer shell is adjusted, and when it moves to correspond to the diseased area, the stroke motor stops rotating; through the extrusion of the water sacs against the back, the diseased area can be exactly stuck at the position between the two water sacs, and then the electric telescopic rod is controlled to contract once. The lever at the end of the electric telescopic rod will squeeze the piston rod, and the medicament in the liquid storage tank is squeezed out and sprayed from the nozzle, and the sprayed medicament can exactly correspond to the diseased area; then the steering motor can be started to enable the water sacs to revolve around the rotating shaft, and in addition, the water sacs can reciprocally swing radially inside the outer shell, forming an effect similar to manual massage.

[0007] However, in the process of applying medicine to the patient, due to the setting of the water sac, after the liquid medicine is sprayed out from the nozzle, it needs to travel a certain distance before it can act on the patient's skin surface. In this way, the sprayed liquid medicine splashes around the affected area, which is very inconvenient to use. Moreover, during the massage process, the upper body of the patient is extremely likely to tilt forward under the squeezing action of the water sac, thus affecting the massage effect. In addition, the device provided by the above technical solution can only apply medicine and massage the patient's back, with a single function. Summary of the Invention

[0087] In addition, features limited to "first" and "second" may explicitly or implicitly include one or more of such features.

[0088] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0089] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0090] The inventors' research found that when the current device for relieving ankylosing spondylitis is in use, the liquid medicine needs to travel a certain distance after being sprayed from the nozzle before it can act on the patient's skin surface. In this way, the sprayed liquid medicine splashes around the affected area, making it very inconvenient to use. Moreover, during the massage process, the upper body of the patient is extremely likely to tilt forward under the squeezing action of the water bag, thus affecting the massage effect.

[0091] In addition, the current device for relieving ankylosing spondylitis can only apply medicine and massage the patient's back, with a single function.

[0092] Based on the above findings, this application provides a spinal activity assistor for ankylosing spondylitis patients. The spinal activity assistor for ankylosing spondylitis patients includes a movable support 4, and a back relief mechanism 1, a neck activity mechanism 2, and two lower limb activity mechanisms 3 provided on the movable support 4. Through the following designs, the medicine application effect and massage effect of the overall device are better, and it can also be used in the exercise for relieving the symptoms of ankylosing spondylitis. Specifically:

[0093] 1. A back relief mechanism 1 is provided on the movable support 4 to simultaneously fix the upper body of the patient, apply medicine to the patient's back, and massage the patient's back. This can improve the efficiency of applying medicine to the patient's back, prevent the upper body of the patient from tilting forward, ensure the massage effect and medicine application effect on the patient's back, and apply medicine to the patient's back while massaging the patient, improving the medicine application efficiency of the overall device.

[0094] 2. A neck activity mechanism 2 is provided on the movable support 4, which can help the patient rotate the neck left and right and improve the spinal mobility.

[0095] 3. Lower limb activity mechanisms 3 are provided on the movable support 4, which can help the patient move the lower limbs and improve the spinal mobility.

[0096] 4. The neck activity mechanism 2 and the back relief mechanism 1 are connected by a torsion spring, and the neck activity mechanism 2 is connected to the movable support through a back fitting mechanism. The inclination angle of the second mounting plate can be adjusted to be suitable for patients with kyphosis.

[0097] 5. The spinal activity assistor provided by the present invention is applicable to the symptomatic relief treatment of ankylosing spondylitis patients, especially applicable to the scenario of applying powder medicine to the back.

[0098] Embodiment 1

[0099] This embodiment provides a spinal activity assistor for ankylosing spondylitis patients, as Figure 1-19 shown, including a movable support 4, and a back relief mechanism 1, a neck activity mechanism 2, and two lower limb activity mechanisms 3 provided on the movable support 4.

[0100] The movable support 4 includes a limit frame and four support legs integrally connected to the limit frame; specifically, the limit frame includes a C-shaped limit rod and a movable rod rotatably connected to the C-shaped limit rod, and the movable end of the movable rod is movably connected to the end of the C-shaped limit rod, so that the patient can rotate the movable rod outwards, and then the patient enters the accommodating cavity formed by the C-shaped limit rod and the movable rod for the patient to use. It should be noted that the movable connection manner of the movable rod and the C-shaped limit rod in the embodiment of the present invention is the prior art, and the embodiment of the present invention does not limit this, for example, the movable rod and the C-shaped limit rod are movably connected by a buckle.

[0101] The back relief mechanism 1 includes: a first mounting plate 11, a medicine application component 12, a massage component 13 and a protection component 14.

[0102] The first mounting plate 11 is an arc-shaped structure; specifically, the first mounting plate 11 is located above the movable support 4 and is fixedly connected to the movable support 4.

[0103] The medicine application component 12 includes a vibrator 12a, a dehydration box 12b and a medicine powder tray 12c; among them, the dehydration box 12b is located inside the massage component 13;

[0104] It should be noted that the vibrator 12a provided in the embodiment of the present invention is the prior art, and the embodiment of the present invention does not improve this, for example, the vibrator 12a includes a box body, a vibrating rod and a rotating motor;

[0105] Specifically, the rotating motor is fixedly arranged in the box body, and the box body is fixedly arranged in the central through hole of the first mounting plate 11; a wavy slideway is arranged on the output end of the rotating motor, and the wavy slideway is slidably connected to the vibrating rod;

[0106] One end of the vibrating rod is located inside the box body, and one end of the vibrating rod is connected to the wavy slideway on the output end of the rotating motor through a slider, and the other end passes through the box body and is sleeved with the first piston 5; among them, the first piston 5 passes through the massage component 13 and is fixedly connected to the dehydration box 12b. Among them, the vibrating rod is a square rod-shaped structure, and correspondingly, a through hole for the vibrating rod to pass through is arranged on the side surface of the box body.

[0107] The working principle of the vibrator 12a provided in the embodiment of the present invention is: after the rotating motor is started, the wavy slideway on the output end rotates, so that the slider cooperating with the wavy slideway moves back and forth in the axial direction of the motor, and then the slider drives the vibrating rod to move back and forth, realizing the vibration of the vibrating rod.

[0108] The first piston 5 includes a fixing piece 51, a sleeve 52, a piston ring 53 and two connecting rods 54;

[0109] Specifically, one end of the fixing piece 51 is fixedly connected to the sleeve 52, and the other end passes through the massage component 13 and is fixedly connected to the dehydration tank 12;

[0110] An opening is provided at one end of the sleeve 52 away from the fixing piece 51, and this opening is used for sleeving the end of the vibrating rod of the vibrator 12a;

[0111] The piston ring 53 is fixedly connected to the fixing piece 51 through two connecting rods 54; in this way, when the vibrating rod of the vibrator 12a extends, the end of the vibrating rod presses against the inner wall of the sleeve 52 and pushes the fixing piece 51 to move forward. At this time, the first piston 5 moves as a whole, that is, the fixing piece 51 drives the piston piece 53 to move forward through the connecting rod 54; when the vibrating rod retracts, the fixing piece 51 returns to the initial position under the extrusion force of the patient's back. At this time, the piston ring 53 returns to the initial position under the drive of the fixing piece 51, thereby realizing the reciprocating motion of the piston ring 53.

[0112] The dehydration tank 12b is of a C-shaped structure and is fixedly connected to the fixing piece 51; the dehydration tank 12b is made of a hard material. By way of example, this hard material can be plastic or metal.

[0113] The flexible piece 12b-1 is arranged on the side of the dehydration tank 12b away from the fixing piece 51 and is fixedly connected to the dehydration tank 12b; wherein, through holes for connecting with the powder tray 12c are provided on the flexible piece 12b-1.

[0114] Specifically, a connector for connecting with the flexible piece 12b-1 is provided on the side surface of the powder tray 12c. The connector is connected to the inside of the powder tray 12c, and a water-permeable membrane 12c-1 is provided inside the end of the connector. It should be noted that the water-permeable membrane 12c-1 is a prior art, and the embodiments of the present invention do not make improvements thereto. By way of example, the water-permeable membrane 12c-1 is a PU water-permeable membrane.

[0115] During actual use, a receiving cavity is formed between the dehydration tank 12b and the flexible piece 12b-1. This receiving cavity is pre-filled with a dehydratable material, and this dehydratable material can be a polyacrylamide polymer. Specifically, this polyacrylamide polymer is (poly N-isopropylacrylamide).

[0116] In this way, since the flexible piece 12b-1 is located between the patient and the dehydration tank 12b, during the process of the fixing piece 51 reciprocating under the action of the vibrating rod, the dehydration tank 12b reciprocates with the fixing piece 51. At this time, the dehydratable material between the dehydration tank 12b and the flexible piece 12b-1 is continuously squeezed, so that the dehydratable material heats up and dehydrates. The dehydrated water passes through the water-permeable membrane 12c-1 and then enters the powder tray 12c connected to the flexible piece 12b-1, so that the dehydrated water and the medicine powder are mixed and then applied to the patient's back, realizing the application of medicine to the patient's back.

[0117] The massage component 13 includes a main massage block 13a, auxiliary massage blocks 13b, and a piston cylinder 13c. Among them, a plurality of auxiliary massage blocks 13b are respectively arranged on both sides of the main massage block 13a, and each auxiliary massage block 13b is used to massage the edge of the patient's back. It should be noted that the number of auxiliary massage blocks 13b is not limited in the embodiments of the present invention. In the embodiments of the present invention, it is exemplified that two auxiliary massage blocks 13b are respectively arranged on both sides of the main massage block 13a.

[0118] The main massage block 13a has a square structure, and connection pieces are integrally connected to both sides of the main massage block 13a respectively. An inflatable box 13f is arranged on each connection piece. Each inflatable box 13f is respectively connected to a group of auxiliary massage blocks 13b, and is communicated with the piston cylinder 13c sleeved on the first piston 5 through a first communication pipe 13e.

[0119] Among them, an accommodation cavity 13a-1 for accommodating the dehydration box 12b is arranged inside the main massage block 13a. Specifically, a through hole communicated with the accommodation cavity is arranged on one side of the main massage block 13a close to the patient, so that the powder tray 12c arranged on the flexible sheet 12b-1 can contact the patient's back. In this way, since the main massage block 13a is sleeved on the dehydration box 12b, while the dehydration box 12b vibrates under the action of the vibrator 12a, the dehydration box 12b drives the main massage block 13a to reciprocate together, so as to realize applying medicine to the patient's back while massaging the patient. Among them, the main massage block 13a is hermetically connected to the powder tray 12c.

[0120] Each auxiliary massage block 13b includes a massage sheet and a piston rod vertically connected to the massage sheet. A second piston 13d is arranged at one end of the piston rod far from the massage sheet. The second piston 13d is located in the inflatable box 13f of the main massage block 13a on the same side, and a return spring is sleeved on the piston rod. The return spring is clamped between the inner wall of the inflatable box 13f and the second piston 13d. In this way, the return spring can assist the second piston 13d to return to the initial position.

[0121] During use, the piston ring 53 is located in the piston cylinder 13c, and the piston ring 53 reciprocates under the drive of the fixing piece 51. In this way, when the piston ring 53 moves away from the patient at one end in the piston cylinder 13c, the gas in the piston cylinder 13c is squeezed into the inflatable box 13f, the pressure in the inflatable box 13f increases, and further makes the second piston 13d on each auxiliary massage block 13b move outward from the inflatable box 13f. At this time, the vibrating sheet of each auxiliary massage block 13b moves outward. When the piston ring 53 moves towards the patient at one end in the piston cylinder 13c, the gas in the inflatable box 13f is drawn into the piston cylinder 13c. At this time, the second piston 13d on each auxiliary massage block 13b moves towards the inside of the inflatable box 13f until the second piston 13 returns to the initial position, so as to realize the vibration of each auxiliary massage block 13b.

[0122] The protection component 14 includes a plurality of protection airbags 14a respectively arranged on both sides of the main massage block 13a, and heating units 14b respectively arranged on both sides of the main massage block 13a; correspondingly, installation grooves for installing the heating units 14b are respectively arranged on both sides of the main massage block 13a.

[0123] Each protection airbag 14a is of an arc structure, and each protection airbag 14a is communicated with the installation groove on the same side through a second communication pipe 14d, and a third piston 14c is fixedly arranged at the end of the second communication pipe 14d. In this way, the heating unit 14b heats the gas in the corresponding installation groove, so that the gas in the installation groove expands, thereby increasing the pressure in the installation groove, and further making the third piston 14c in each second communication pipe 14d connected to the installation groove move towards the inside of the protection airbag 14a, so that the protection airbag 14a expands, so as to wrap the patient's waist with the protection airbag 14a, thereby realizing the fixation of the patient's upper limb.

[0124] In order to further improve the fixation effect on the patient's upper limb, it further includes a strap 14e, and both ends of the strap 14e are fixedly connected to both ends of the first mounting plate 11.

[0125] It should be noted that the number of the protection airbags 14a is not limited in the embodiment of the present invention. By way of example, the embodiment of the present invention takes three protection airbags 14a respectively arranged on both sides of the main massage block 13a as an example for illustration.

[0126] The heating unit 14b includes a heating wire, a thermistor and a power supply; the heating wire, the thermistor and the power supply are all connected through wires. It should be noted that the electrical connection manner of the heating wire, the thermistor and the power supply provided in the embodiment of the present invention is the prior art, and the embodiment of the present invention does not make improvements thereto.

[0127] During actual use, the power supply can be turned on to energize the heating wire, so as to heat the gas in the installation groove, so that the gas in the installation groove expands, thereby increasing the pressure in the installation groove, and further making the third piston 14c in each second communication pipe 14d connected to the installation groove move towards the inside of the protection airbag 14a, so that the protection airbag 14a expands, so as to wrap the patient's waist with the protection airbag 14a, thereby realizing the fixation of the patient's upper limb and improving the comfort of the patient during use.

[0128] The working principle of the back relief mechanism 1 provided by the embodiment of the present invention is as follows:

[0129] Start the vibrator 12a, and the vibrator 12a repeatedly impacts the fixed piece 51. After each impact on the fixed piece 51, the patient's back provides a reverse thrust to the fixed piece 51, so that the fixed piece 51 returns to the initial position, thereby realizing the reciprocating movement of the first piston 5;

[0130] During the reciprocating movement of the first piston 5, the first piston 5 drives the dehydration box 12b to reciprocate, so that the dehydratable material between the dehydration box 12b and the flexible sheet 2b-1 is repeatedly squeezed. As a result, the dehydratable material is heated and dehydrated under the action of friction. The dehydrated water enters the powder tray 12c through the water-permeable membrane 12c-1 and combines with the powder, which is convenient for applying the powder to the patient's back. At the same time, since the main massage block 13a is sleeved on the dehydration box 12b, when the first piston 5 drives the dehydration box 12b to reciprocate, the main massage block 13a reciprocates with the dehydration box 12b to massage the patient's back while applying medicine to the patient;

[0131] While the first piston 5 drives the dehydration box 12b to reciprocate, the fixing piece 51 squeezes the gas in the piston cylinder 13c into the inflatable box 13f of the main massage block 13a. At this time, each second piston 13d connected to the inflatable box 13f moves outward from the inflatable box 13f, so that each auxiliary massage block 13 moves outward to squeeze the patient's skin surface. Then, the fixing piece 51 is squeezed by the patient's back and returns to the initial position. At this time, the gas in the inflatable box 13f is squeezed into the piston cylinder 13c, and each second piston 13d connected to the inflatable box 13f moves into the inflatable box 13f, so that each auxiliary massage block 13 returns to the initial position. By repeating this process, the massage of the edge of the patient's back is realized, and the massage of the patient's back and the edge of the back is realized while applying medicine to the patient;

[0132] When the vibrator 12a is started, the power supply 14b-3 is started at the same time, so that the heating wire heats the air in the corresponding installation groove, causing the gas in the installation groove to expand, thereby increasing the pressure in the installation groove. Then, the third piston 14c in each second communication pipe 14d connected to the installation groove moves into the interior of the protective airbag 14a, causing the protective airbag 14a to expand, so as to wrap the patient's waist with the protective airbag 14a, thereby realizing the fixation of the patient's upper limbs.

[0133] The neck movement mechanism 2 includes a second mounting plate 21, a first handle 22, a neck moving member 23, a neck airbag ring 24, a connecting rope 25, an elastic rod 26, and a blowing assembly 27.

[0134] The second mounting plate 21 is a plate-like structure, and the upper end of the second mounting plate 21 is rotatably connected to the upper end of the first mounting plate 11 through a torsion spring; specifically, a first handle 22 is provided on each side of the second mounting plate 21, and each first handle 22 is rotatably connected to the second mounting plate 21;

[0135] The neck movable member 23 is arranged at the upper end of the second mounting plate 21 and is rotatably connected to the second mounting plate 21; specifically, the neck movable member 23 is respectively connected to the two first handles 22 through two connecting ropes 25;

[0136] The neck airbag ring 24 is arranged on the side of the neck movable member 23 close to the patient, and the neck airbag ring 24 is fixedly connected to the neck movable member 23; specifically, both ends of the neck airbag ring 24 are fixedly connected to the neck movable member 23 through elastic rods 26.

[0137] Taking the first handle 22 at the right hand of the patient as an example, when assisting the patient to perform rotational exercise on the neck, the first handle 22 can be rotated and unfolded outwards. At this time, the first handle 22 drives the neck movable member 23 to rotate to the right through the connecting rope 25. At this time, the neck movable member 23 drives the patient's neck to rotate to the right, realizing the rotational exercise of the patient's neck.

[0138] As Figure 13 shown, the blowing component 27 includes a blowing box 27a, a fourth piston 27b, a third connecting pipe 27c and an elastic member 27d. Specifically, the elastic member 27d is a spring.

[0139] The blowing box 27a is embedded in the second mounting plate 21; specifically, a convex cavity is provided in the blowing box 27a, and the blowing box 27a is provided with a plurality of air outlets, and the plurality of air outlets are communicated with the convex cavity;

[0140] The fourth piston 27b is located in the convex cavity of the blowing box 27a, and the fourth piston 27b is connected to one end of the third connecting pipe 27c far from the neck airbag ring 24;

[0141] One end of the third connecting pipe 27c far from the fourth piston 27b is communicated with the neck airbag ring 24. In practical applications, the neck airbag ring 24 is communicated with the fourth piston 27b through two third connecting pipes 27c.

[0142] When the patient performs nodding exercise, the end of the neck airbag ring 24 is squeezed by the patient's mandible, so that the gas inside the neck airbag ring 24 moves towards the third connecting pipe 27c. At this time, the pressure on the upper end of the fourth piston 27b becomes larger, so that the fourth piston 27b moves downwards. In this way, the gas in the blowing box 27a flows out from the air outlet to blow and cool the patient's neck position; in the above process, the elastic rod 26 deforms along with the neck airbag ring 26, and the elastic member 27d is compressed;

[0143] When the patient raises their head, the neck airbag ring 24 is no longer squeezed by the patient's mandible. Under the action of the elastic rod 26, the neck airbag ring 24 returns to its natural state. At this time, the pressure on the upper surface of the fourth piston 27 decreases, and under the action of the elastic member 27d, the fourth piston 27 returns to its initial position so that when the patient nods for exercise next time, the patient's neck position can be cooled by blowing air.

[0144] At both ends of the movable bracket 4, a lower limb movement mechanism 3 is respectively provided. Each lower limb movement mechanism 3 includes a second handle 31, a movable connecting rod 32, and two fixing bolts 33.

[0145] Specifically, the second handle 31 is rotatably connected to the movable bracket 4, and the lower end of the second handle 31 is fixedly connected to the movable connecting rod 32.

[0146] The movable connecting rod 32 includes a first connecting rod and a second connecting rod; specifically, one end of the first connecting rod is fixedly connected to the lower end of the second handle 31, and the other end is rotatably connected to the second connecting rod; wherein, a strap for fixing the patient's thigh is provided on the first connecting rod, and a strap for fixing the patient's calf is provided on the second connecting rod.

[0147] The fixing bolt 33 is detachably connected to the movable connecting rod 32; it should be noted that the embodiment of the present invention does not limit the detachable connection method between the fixing bolt 33 and the movable connecting rod 32. By way of example, the fixing bolt 33 is threadedly connected to the movable connecting rod 32; correspondingly, a through hole for the fixing bolt 33 to pass through is provided on one of the connecting rods of the movable connecting rod 32, and a threaded hole connected to the fixing bolt 33 is provided on the other connecting rod.

[0148] In actual use, if the patient needs to perform high knee lifts, the fixing bolt 33 is removed, then the second handle 31 is held by hand and pulled towards the body side. At this time, the second handle 31 drives the first connecting rod to rotate, thereby lifting the patient's thigh and assisting the patient in performing high knee lift exercises.

[0149] If the patient needs to perform kicking actions, the fixing bolt 33 is connected to the movable connecting rod 32 to lock the first connecting rod and the second connecting rod. Then, the second handle 31 is pulled towards the patient's body side. At this time, the second handle 31 drives the first connecting rod to rotate, assisting the patient in performing kicking exercises.

[0150] At both ends of the movable bracket 4, a back fitting mechanism 6 is respectively provided. Each back fitting mechanism 6 includes an adjustment turntable 61, an adjustment rope 62, a clamping device 63, and a limit spring 64.

[0151] The adjustment turntable 61 is arranged on the side of the movable bracket 4 and is fixedly connected to the movable bracket 4;

[0152] One end of the adjusting rope 62 is fixedly connected to the adjusting turntable 61, and the other end is fixedly connected to the side of the second mounting plate 21;

[0153] The clamping device 63 is arranged on the same side as the adjusting turntable 61 and is fixedly connected to the movable bracket 4; specifically, the clamping device 63 includes a collar and a clamping bolt threadedly connected to the collar; wherein, a C-shaped clamping block is provided at one end of the clamping bolt close to the adjusting turntable 61.

[0154] The limiting spring 64 is sleeved on the adjusting rope 62 to limit the movement range of the adjusting rope 62 and prevent the adjusting rope 62 and the second handle 31 from interfering with each other.

[0155] During actual use, medical staff or patients first rotate and remove the clamping bolt in the clamping device 63, then rotate the adjusting turntable 61 to wind the adjusting rope 62 around the adjusting turntable 61, and then thread the clamping bolt onto the collar. At this time, the C-shaped clamping block provided at the end of the tightening bolt is in close contact with the adjusting turntable 61 to prevent the adjusting turntable 61 from rotating, thereby realizing the adjustment of the inclination angle of the second mounting plate 21 to be suitable for patients with hunchbacks.

[0161] Step 3: Start the vibrator 12a and the heating unit 14b simultaneously;

[0162] In this step, the end of the vibrating rod in the vibrator 12a repeatedly hits the fixed piece 51, causing the first piston 5 to vibrate;

[0163] While the first piston 5 vibrates, it drives the dewatering tank 12b to vibrate. At this time, the dehydratable material located in the dewatering tank 12b is continuously squeezed by the patient's back and heats up, so that the dehydratable material is heated and dehydrated. The water discharged passes through the water permeable membrane 12c-1 and is mixed with the medicinal powder to form a paste, so as to apply the paste-shaped medicine to the patient's back. At the same time, the first piston 5 drives the main massage block 13a to reciprocate, realizing vibration massage on the patient's back while applying medicine to the patient's back;

[0164] While the first piston 5 vibrates, the first piston 5 repeatedly inflates or sucks air into the inflatable box 13f, so that the second piston 13d connected to each inflatable box 13f reciprocates, so that the massage sheets correspondingly connected to the respective second pistons 13d reciprocate, realizing vibration massage of the patient's back while massaging the edge of the patient's back;

[0165] The heating unit 14b heats the installation groove, so that the gas in the installation groove expands, so that the pressure in the installation groove increases, and further makes the third piston 14c in each second communication pipe 14d connected to the installation groove move toward the inside of the protective airbag 14a, so that the protective airbag 14a expands, so as to wrap the patient's waist with the protective airbag 14a, thereby realizing the fixation of the patient's upper limbs, ensuring the safety of the patient, and ensuring the medicine application and massage effects on the patient, and relieving the discomfort of the patient's back.
