Description

Technical Field

[0001] The invention belongs to the technical field of joint protection devices, and in particular relates to a clinical joint protection device for rheumatology. Background Art

[0002] In daily life, rheumatism is a common and widespread disease, which mostly occurs in the knee joints, especially in rainy weather. The joints are extremely painful, which greatly affects the daily life of patients. Some serious cases may cause joint deformation. At this time, in order to relieve the pain, most patients wear more clothes to keep warm and increase the temperature of the joints. However, the effect is not satisfactory and the effect is poor. At the same time, when rheumatic diseases occur, patients have difficulty walking and the knee joints can hardly bear the weight of the body, which aggravates the condition and increases the pain of patients.

[0003] At present, the sheath used for rheumatism protection mainly includes a protective body and a connecting elastic belt for connecting the protective body. The connecting elastic belts are located on both sides of the protective body. When fixing the protective body, the Velcro on the two connecting elastic belts can be used, which is simple and convenient. The protective body usually includes a windproof layer and a heating layer. The windproof layer can prevent the external cold wind from affecting the knees, and the heating layer has a heating rod or a hot water bag for heating the knees. However, the wrapping protective device has a single function and cannot protect the joints while helping patients recover early and providing a comfortable massage.

[0004] In response to this problem, the existing application number is "201911085567.2", and the name is "A clinical joint protection device for rheumatology". The device includes a knee pad protective cover, the upper part of the knee pad protective cover is fixedly provided with an upper elastic fixing belt, the lower part of the knee pad protective cover is fixedly provided with a lower elastic fixing belt, the right side of the knee pad protective cover is fixedly provided with a knee pad, and the right inner wall of the knee pad is fixedly provided with an electric massage telescopic rod. The clinical joint protection device for rheumatology in the prior art can provide anti-collision protection against external forces through the knee pad protective cover and the knee pad, and can keep the knee joint in the knee pad warm through the cooperation of the electric heating wire insulation tube and the temperature controller to prevent the pain in the rheumatic knee joint caused by cold or rainy days. The patient's knee joint can be massaged through the massage roller and the rubber massage ball to make the blood circulation in the patient's joint smooth and achieve the effect of reducing swelling and relieving pain, which is ultimately conducive to convenient and quick treatment and protection of the patient's knee joint.

[0005] However, the device still has the following problems: 1. The device can only achieve simple massage, and does not achieve the effect of simultaneous massage and drug treatment. Through long-term clinical treatment experience, it is found that after massage, the patient's skin pores open and the blood flow rate accelerates. At this time, if combined with drug infiltration, it will achieve twice the result with half the effort; 2. The massage device is provided with a buffer device. According to the buffer principle of the device, the massage will first be buffered by the buffer device during massage, which will actually greatly reduce the effect of massage. In actual massage therapy, direct force application will have better effect. Summary of the invention

[0035] When the upper shell 101 and the lower shell 102 need to be engaged, the push rod 107 is pushed to push the movable engaging rod 106 inward, the spring 108 is compressed, and then the end faces of the upper fixed block 104 and the lower fixed block 105 are in contact, the engaging rod 106 is inserted into the upper groove 1041, and the push rod 107 is released. Under the action of the spring 108 returning to the original position, the movable engaging rod 106 slides outward, and its engaging teeth 1061 engage with the engaging groove 10411, thereby achieving a fixed connection.

[0036] When the upper shell 101 and the lower shell 102 need to be separated, the above operation is performed, except that only the upper fixing block 104 and the lower fixing block 105 need to be separated.

[0037] The massage mechanism includes a power component 2 and a massage and medication-dispensing linkage component 3. The power component is disposed on the upper housing 101 and drives the massage and medication-dispensing linkage component to move.

[0038] The power assembly includes a motor 201, a gear set 202, a rotating body 203, a turntable 204, a screw 205 and an arc rod 206. The gear set 202 includes a driving gear 2021, a first driven gear 2022, a second driven gear 2023, and a third driven gear 2024 that are meshed with each other. The motor 201 is arranged in the upper shell 101. Specifically, the gear set 202 is located in an arc groove of the upper shell 101, the motor 201 is fixedly set in a groove opened on the side wall of the arc groove, and the turntable 204 is located in another arc groove of the upper shell 101.

[0039] The motor 201 drives the active gear 2021 to rotate, and the output shafts of the active gear 2021 and the third driven gear 2024 are respectively connected to the rotating body 203. The ends of the rotating body 203 are integrally formed sector blocks 2031 and strip blocks 2032. The ends of the strip blocks 2031 are formed with cylindrical blocks 2033. Two turntable grooves 2041 that cooperate with the cylindrical blocks 2033 are symmetrically provided on the turntable 204. The outer periphery of the turntable 204 is four arc-shaped concave surfaces that cooperate with the curved surfaces of the sector blocks 2031. The end of the turntable 204 is fixedly connected to the screw 205. The screw 205 is threadedly arranged on the upper shell 101. The other end of the screw 205 passes through the side wall of the arc groove of the upper shell 101 and is fixedly connected to the arc rod 206. The arc rod 206 is connected to the massage and medication linkage assembly.

[0040] During operation, the motor 201 drives the driving gear 2021 to rotate, the driving gear 2021 drives the first driven gear 2022 to rotate, the first driven gear 2022 drives the second driven gear 2023, and the second driven gear 2023 drives the third driven gear 2024 to rotate.

[0041] If the driving gear 2021 drives its corresponding rotating body 203 to rotate clockwise, it drives the rotating disk 204 to rotate counterclockwise, and the third driven gear 2024 rotates counterclockwise, and drives its corresponding rotating body 203 to rotate counterclockwise. When the rotating disk 204 rotates clockwise to a certain angle and separates, the rotating body 203 of the third driven gear 2024 will be inserted into the rotating disk groove 2041 of the rotating disk 204 and drive it to rotate counterclockwise. Thus, the rotating disk 204 will continuously cycle clockwise and counterclockwise.

[0042] At the same time, the screw rod 205 will be driven to rotate forward and reverse, thereby driving the arc rod 206 to move forward and backward, and to rotate forward and reverse synchronously.

[0043] The massage and medication linkage assembly 3 includes two sets of symmetrically arranged piston cylinders 301 and massage balls 302. A piston rod 303 is arranged in the piston cylinder 301. The end of the piston cylinder 301 is rotatably connected to a connecting rod 304. The end of the connecting rod 304 is hinged to the inner wall of the upper shell 101, thereby fixing the piston cylinder 301, which essentially provides support for the entire massage and medication linkage assembly 3. The free end of the piston rod 303 is fixedly connected to the end of the arc rod 206.

[0044] The bottom surface of the upper housing 101 is fixedly provided with a drug storage cartridge 4, which is connected to the piston cylinder 301 through an infusion tube 401, and a one-way valve 5 is provided at the end of the infusion tube 401 in the piston cylinder 301. The piston cylinder 301 and the massage ball 302 are connected through a hollow tube 305. Among them, micropores are provided on the massage ball to facilitate the penetration of the drug solution.

[0045] Based on the working principle of the above-mentioned power assembly, the rotation of the arc rod 206 will drive the rotation of the massage ball 302, thereby realizing the massage and hammering of the patient's knee joint. At the same time, the forward and backward movement of the arc rod 206 will realize the reciprocating movement of the piston rod 303 through the forward and backward reciprocating motion, and deliver the medicine to the massage ball 302. When the piston rod 303 is withdrawn, negative pressure is generated in the piston cylinder 301, forcing the one-way valve to open a certain angle, and the medicine enters the piston cylinder 301 from the infusion tube 401. The piston rod 303 pushes the tube, generating positive pressure, and the one-way valve closes, and the liquid flows into the massage ball. During the hammering process of the massage ball, under the action of gravity, the medicine first enters the massage ball that contacts one side of the joint, and cooperates with the massage to penetrate into the joint skin.

[0046] Furthermore, the inner surface of the upper body 101 is provided with a mesh fabric 7, which can buffer the massage force and penetrate the medicine solution.

He uses the rheumatology clinical joint protection device of the present invention for treatment and rehabilitation.

[0049] First, the patient's calf is placed on the supporting arc plate 601, and the Velcro bandage 603 fixes it. Then, the knee is placed in the outer shell 1 and fixed by the clamping assembly. Then the power assembly 2 is started to drive the massage ball 302 of the massage and medication linkage assembly 3 to rotate, thereby realizing massage and hammering of the patient's knee joint. At the same time, the arc rod 206 moves forward and backward, and the liquid medicine is pumped into the massage ball through the piston device. During the hammering process of the massage ball, the liquid medicine contacts the massage ball on one side of the joint, and cooperates with the massage to penetrate into the joint skin. Finally, the treatment of the patient's knee arthritis is achieved.
