Description

Technical Field

[0001] The present invention relates to the technical field of joint care equipment, and in particular to a knee joint care device for rheumatology and immunology departments. Background Art

[0002] Rheumatoid arthritis is caused by autoimmune dysfunction, which leads to joint stiffness and swelling, resulting in the inability of the joints to move independently. Patients with rheumatoid arthritis should usually pay attention to keeping the joints warm and recover slowly through moderate exercise.

[0003] In the early stage of rheumatoid arthritis, due to the swelling of the joint muscles, recovery cannot be achieved through autonomous movement. In terms of care, external force is usually needed to achieve joint movement, and then cooperate with insulation equipment to meet the warmth needs of the joints. Existing insulation equipment for joints is usually achieved through insulation bags. The insulation bags are wrapped around the joints, and then powered on. The electric heating elements inside the insulation bags generate heat to keep the joints warm. However, after wearing this insulation bag, the patient's own joints cannot move, and thus cannot cooperate with appropriate exercise to accelerate recovery.

[0004] In order to solve the above problems, a rheumatology and immunology knee joint care device is now proposed. Summary of the invention

[0005] In view of the above problems, the present invention provides a rheumatology and immunology knee joint care device, which solves the problem that the existing insulation equipment used in the care of rheumatoid arthritis is usually realized by a heat preservation bag, which is wrapped around the joint and then powered on.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the invention more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In the description of the invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the invention.

[0021] refer to Figures 1 to 12 , a joint warming device for nursing in rheumatology and immunology department, comprising an n-shaped base 1, a vertical plate 16, a thigh fixing barrel 10, a calf fixing barrel 9, an operating rod 11, a movable mechanism, a thigh massage mechanism, a back massage mechanism, a transmission mechanism, and a calf massage mechanism; Operating rods 11 are movably mounted on both sides of the horizontal plate of the n-type base 1, a vertical plate 16 is mounted on the upper end of the first vertical plate of the n-type base 1, and a back massage mechanism is movably mounted on the first side wall of the vertical plate 16. Both operating rods 11 movably drive the back massage mechanism to work. The n-type base 1 is a supporting component of the device, and the operating rod 11 is a driving component of the device. The user can drive the back massage mechanism to work by pushing and pulling the operating rod, and the back massage mechanism can effectively massage the back of the user as the user pushes and pulls the operating rod 11 back and forth; A transmission mechanism is installed on the second side wall of the vertical plate 16. The transmission mechanism is driven by the back massage mechanism. The transmission mechanism works synchronously with the back massage mechanism to drive the calf massage mechanism described later to start working. A calf massage mechanism is installed at the lower end of the horizontal plate of the n-shaped base 1, and the calf massage mechanism is driven by the transmission mechanism to massage the user's calf under the drive of the transmission mechanism; Thigh fixing barrels 10 are fixedly installed on both sides of the upper end of the second vertical plate of the n-shaped base 1, and calf fixing barrels 9 are hingedly installed on the lower ends of the two thigh fixing barrels 10. The two calf fixing barrels 9 are driven to move by a movable mechanism. The calf fixing barrels 9 are used to fix the patient's calf, and with the driving of the movable mechanism, the calf fixing barrels 9 will drive the patient's calf to swing up and down, thereby realizing the activity exercise of the patient's joints; The two operating rods 11 both drive the two movable mechanisms to work, and the user can also drive the movable mechanisms by pushing and pulling the operating rods 11 back and forth; Thigh massage mechanisms are installed on both sides of the two thigh fixing barrels 10. The thigh massage mechanisms on the same side are driven to work by the movable mechanisms on the same side. The thigh massage mechanisms will work synchronously with the working of the movable mechanisms, thereby massaging both sides of the user's thighs and increasing the comfort of use. The same flexible thermal pad is installed on the inner top wall of the thigh fixing barrel 10 and the calf fixing barrel 9 located on the same side. The flexible thermal pad is electrically connected to an external power supply. When the thermal pad is powered on and worn on the patient's joints, the electric heating element inside the thermal pad starts to heat up to keep the patient's joints warm. The maximum temperature of the flexible thermal pad after heating is less than 50°C to avoid scalding the patient's skin. This is existing technology and will not be elaborated here.

[0022] The back massage mechanism comprises a sliding sleeve 13, a first massage wheel frame 14, a first massage wheel 15, and a first connecting rod 3; First T-shaped slide grooves 101 are respectively provided on both sides of the horizontal plate of the n-shaped base 1, and the horizontal plates of the first T-shaped slide blocks 18 are respectively slidably installed in the horizontal grooves of the two first T-shaped slide grooves 101; First rotating shafts are fixedly installed on the outer sides of the vertical plates of the two first T-shaped sliding blocks 18, and the two first rotating shafts are fixedly connected to the bottom ends of the two operating rods 11 respectively; The outer ends of the two first rotating shafts are rotatably mounted with the first ends of the first connecting rods 3, and the two first connecting rods 3 are rotatably arranged on the outer sides of the two operating rods 11. The outer sliding sleeve of the vertical plate 16 is provided with a sliding sleeve 13, and the second ends of the two first connecting rods 3 are rotatably connected to the left and right side walls of the sliding sleeve 13 respectively; First massage wheel frames 14 are respectively vertically mounted on both ends of the front side wall of the sliding sleeve 13, and a plurality of first massage wheels 15 for massaging the patient's back are rotatably mounted in the two first massage wheel frames 14; The sliding sleeve 13 works by sliding the transmission mechanism. The user slides the operating rods 11 on both sides of the reciprocating sliding device. The two operating rods 11 drive the first T-shaped sliders 18 on both sides to slide reciprocatingly along the first T-shaped slide grooves 101 on both sides through reciprocating sliding. The cooperation between the first T-shaped sliders 18 and the first T-shaped slide grooves 101 ensures the sliding tracks of the two operating rods 11 and ensures that they will not fall off during the sliding process. The two operating rods 11 drive the first connecting rods 3 on both sides to start to deflect up and down during the reciprocating sliding activity. The two first connecting rods 3 are moved upward and downward. During the downward deflection, the sliding sleeve 13 is driven to slide up and down along the vertical plate 16. The interior of the sliding sleeve 13 is a rectangular through groove that cooperates with the vertical plate 16 to ensure that it will not separate during the sliding process. During the up and down sliding process of the sliding sleeve 13, the first massage wheel frame 14 is driven to slide up and down. During the up and down sliding process of the first massage wheel frames 14 on both sides, the first massage wheels 15 inside thereof are driven to slide up and down. The user's back contacts the first massage wheel 15, driving the first massage wheel 15 to roll, thereby massaging the user's back.

[0023] The transmission mechanism comprises a rack plate 22, a first spur gear 21, and a second spur gear 23; Rack plates 22 are fixedly mounted on both sides of the middle end of the rear side wall of the sliding sleeve 13, and the two rack plates 22 are arranged back to back; The outer sides of the two rack plates 22 are respectively meshed with first spur gears 21, and the two first spur gears 21 are respectively rotatably arranged on the outer wall of the first vertical plate of the n-shaped base 1 through the second rotating shaft; The lower ends of the two first spur gears 21 are respectively meshed with second spur gears 23, and the two second spur gears 23 are rotatably mounted on the outer wall of the first vertical plate of the n-shaped base 1 through thrust bearings; The diameter of the first spur gear 21 is greater than the diameter of the second spur gear 23; The two second spur gears 23 respectively drive the calf massage mechanism to work by rotating, and the sliding sleeve 13 drives the two rack plates 22 fixed thereon by sliding up and down. The two rack plates 22 also start to slide up and down driven by the sliding sleeve 13 and drive the first spur gears 21 meshing therewith to start reciprocating rotation during the sliding process. The two first spur gears 21 respectively drive the second spur gears 23 meshing therewith by reciprocating rotation. The second spur gear 23 also starts to reciprocate under the drive of the first spur gear 21, and drives the calf massage mechanism described later to start working during the reciprocating rotation. The diameter of the second spur gear 23 is smaller than that of the first spur gear 21. The purpose is to ensure that the second spur gear 23 can have a faster rotation speed.

[0024] The calf massage mechanism comprises a T-shaped slide plate 25, a flip plate 6, a threaded rod 2502, a second massage wheel 7, and a first return spring 2501; Guide rails 24 are vertically mounted at both ends of the inner wall of the first vertical plate of the n-shaped base 1, and the lower ends of the two guide rails 24 are respectively provided with second T-shaped sliding grooves 2401; T-shaped slide plates 25 are slidably installed in the two second T-shaped slide grooves 2401 respectively; The first ends of the two T-shaped slide plates 25 are respectively threadedly connected to the first ends of the threaded rods 2502, and the other ends of the two threaded rods 2502 are respectively rotated to penetrate the first vertical plate of the n-shaped base 1 and are fixedly connected to the two second spur gears 23; The threads of the two threaded rods 2502 are in opposite directions; The second ends of the horizontal plates of the two T-shaped slides 25 are respectively rotatably mounted with the first ends of the flip plates 6, and the bottom walls of the two flip plates 6 are respectively connected to the second end vertical plates of the two T-shaped slides 25 through the first return springs 2501; The second ends of the two flip plates 6 are respectively rotatably mounted with second massage wheels 7 for massaging the patient's calves. The two second spur gears 23 start to reciprocate at a faster speed driven by the two first spur gears 21, and transmit the rotational driving force to the threaded rods 2502 on both sides. The threaded rods 2502 on both sides respectively drive the T-shaped slide plates 25 on both sides to slide reciprocatingly along the second T-shaped slide grooves 2401 on both sides during the reciprocating rotation. The two second T-shaped slide grooves 2401 will respectively drive the flip plates 6 on both sides to slide along the second T-shaped slide grooves 2401 during the reciprocating sliding process. Figure 5When the T-shaped slide plate 25 slides out to the left, it drives the flip plate 6 connected thereto to start sliding out to the left. When the T-shaped slide plate 25 slides to the leftmost end of the second T-shaped slide groove 2401, the flip plate 6 will also maintain a horizontal state under the elastic force of the first return spring 2501. The first return spring 2501 provides an upward elastic force for the flip plate 6 that is not less than the gravity of the flip plate 6 itself. When the flip plate 6 slides out to the left, it drives the second massage wheel 7 on the front side to slide forward as well. At this time, the user's calf is just in the process of rotating downward. During this process, the user's calf begins to contact the second massage wheel 7, causing the second massage wheel 7 to roll along the bottom of the user's calf to achieve massage. The second massage wheel 7 moves along the As the calf rolls downward, the flip plate 6 also starts to rotate downward and begins to compress the first return spring 2501. The first return spring 2501 provides an upward elastic force for the flip plate 6 during the compression process. At this time, the second massage wheel 7 can also massage the back of the patient's calf with a certain force. When the patient's calf starts to rotate upward with the movable mechanism, the calf will gradually break away from the contact with the second massage wheel 7. At this time, the flip plate 6 is no longer subjected to the pressure of the user's calf. The first return spring 2501 resets the flip plate 6 to a position flush with the T-shaped slide plate 25 again, and gradually retracts into the second T-shaped slide groove 2401 as the T-shaped slide plate 25 slides to the right.

[0025] The movable mechanism comprises a second T-shaped slider 17, a second connecting rod 2, a third connecting rod 4, a first rotating connecting block 5, a first main shaft 27, a second main shaft 2701, and a guide rod 8; The second vertical plate of the n-shaped base 1 is provided with third T-shaped slots 102 on both sides, and the horizontal plates of the second T-shaped sliders 17 are slidably installed in the horizontal grooves of the two third T-shaped slots 102, and the third rotating shafts are fixedly installed on the outer side walls of the vertical plates of the two second T-shaped sliders 17; The first ends of the second connecting rods 2 are rotatably mounted on the outer ends of the two third rotating shafts, and the second ends of the two second connecting rods 2 are rotatably connected to the two first rotating shafts respectively; The second ends of the two second connecting rods 2 are respectively arranged on the inner sides of the two operating rods 11; The first ends of the third connecting rods 4 are rotatably mounted on the two third rotating shafts, and the two third connecting rods 4 are respectively arranged on the inner sides of the two second connecting rods 2; The inner walls of the second ends of the two third connecting rods 4 are rotatably mounted with first rotating connecting blocks 5, and the inner side walls of the two first rotating connecting blocks 5 are respectively fixedly mounted with first T-shaped connecting blocks 501; The first mounting blocks 901 are respectively installed at the middle of the lower ends of the two calf fixing barrels 9, and the first ends of the first main shafts 27 are respectively rotatably installed on the inner walls of the vertical rods of the two first T-shaped connecting blocks 501; The second ends of the two first main shafts 27 rotate through the vertical plates of the two first mounting blocks 901 on which the second T-shaped connecting blocks 502 are mounted, and the second rotating connecting blocks 503 are fixedly mounted on the outer walls of the horizontal plates of the two second T-shaped connecting blocks 502; The two first rotating connecting blocks 5 and the two second rotating connecting blocks 503 respectively drive the two thigh massage mechanisms to work through movement; The lower ends of the two thigh fixing barrels 10 are respectively fixedly mounted with second mounting blocks 1001, and the two second mounting blocks 1001 are respectively connected to the upper ends of the second vertical plates of the n-shaped base 1 through limitable telescopic rods 28; Guide rods 8 are slidably installed in the vertical rods of the first T-shaped connecting block 501 and the second T-shaped connecting block 502 located on both sides of the same calf fixing barrel 9, and a second main shaft 2701 is installed between the upper ends of the guide rods 8 located on both sides of the same calf fixing barrel 9. The second main shaft 2701 is rotatably connected with the second mounting block 1001 at the lower end of the thigh fixing barrel 10 of the calf fixing barrel 9 on the same side. As the user pushes and pulls the operating rods 11 on both sides back and forth, the two operating rods 11 will also drive the second connecting rods 2 on both sides to start to deflect up and down during the reciprocating sliding process. During the process of the two second connecting rods 2 deflecting up and down, the second T-shaped sliding blocks 17 on both sides will be driven to slide up and down along the third T-shaped sliding grooves 102 on both sides. During the process of sliding up and down, the second T-shaped sliding blocks 17 on both sides will drive the third connecting rods 4 on both sides to start to deflect up and down. During the up and down deflection process of the rod 4, the first rotating connecting blocks 5 on both sides of its end portion respectively start to deflect up and down. During the up and down deflection process, the first rotating connecting blocks 5 on both sides also start to rotate under the restrictions of the first main axis 27 and the second main axis 2701. During the rotation process, the two first rotating connecting blocks 5 start to drive the guide rod 8 on one side to slide along the first T-shaped connecting block 501 and the second T-shaped connecting block 502 on both sides of the calf fixing barrel 9 on the same side. During this process, the two guide rods 8 start to rotate up and down and drive the two first mounting blocks 901 to rotate up and down during the rotation process. During the up and down rotation process, the two first mounting blocks 901 will drive the two calf fixing barrels 9 to start to rotate up and down. During the up and down rotation process, the two calf fixing barrels 9 drive the two calves to start to rotate up and down, thereby realizing the exercise needs of their own joints.

[0026] The thigh massage mechanism comprises a connecting plate 12, a second massage wheel frame 1201, and a third massage wheel 26; The first ends of the connecting plates 12 are fixedly mounted on the tops of the outer walls of the first rotating connecting block 5 and the second rotating connecting block 503 located on both sides of the same calf fixing barrel 9, respectively.

As the first rotating connecting blocks 5 and the second rotating connecting blocks 503 on both sides of the same calf fixing barrel 9 start to rotate during the deflection process, the connecting plates 12 located on the upper sides of the first rotating rod connecting blocks 5 and the second rotating connecting blocks 503 also move accordingly and drive the second massage wheel racks 1201 fixed thereto to start moving during the movement. The second massage wheel racks 1201 located on both sides of the same thigh fixing barrel 10 will drive the third massage wheels 26 rotatably installed therein to start moving as they move, and the third massage wheels 26 on both sides of the thighs start to roll as they move on both sides of the thighs, thereby achieving a massage effect on the patient's thighs.

[0027] The upper ends of the thigh fixing barrel 10 and the matching calf fixing barrel 9 are respectively provided with arc grooves for facilitating the patient's joint movement. The arc grooves are used to reserve movable parts for the patient's joint movement to avoid rigid contact between the joint and the equipment. Flexible arc plates 29 are movably installed in the two thigh fixing barrels 10 and the two calf fixing barrels 9. The four flexible arc plates 29 are respectively connected to the inner walls of the two thigh fixing barrels 10 and the inner bottom walls of the two calf fixing barrels 9 through a plurality of second return springs 2901. The flexible arc plates 29 are used to support the patient's legs and can meet the requirements of wearing of legs of different thicknesses under the elastic force of the second return springs 2901, and have a wider range of applications. The flexible heat-conducting pads in the thigh fixing barrel 10 and the calf fixing barrel 9 located on the same side are respectively arranged in two arc grooves that cooperate with each other.

Figure 1 When the user pushes the operating rods 11 on both sides forward, the user's calf will gradually drop down and become perpendicular to the ground under the drive of the calf fixing barrel 9, and at the same time, the T-shaped slide plate 25 will be pushed forward and drive the flip plate 6 to be pushed forward. At this time, the second massage wheel 7 in front of the flip plate 6 starts to roll behind the user's calf along with the pressed calf, so as to achieve the massage effect on the calf; When the user pushes and pulls the operating rods 11 on both sides back and forth, the connecting plates 12 on both sides of the same thigh fixing barrel 10 begin to move. During the movement, the connecting plates 12 drive the second massage wheel frame 1201 to move on both sides of the user's thighs. At this time, the third massage wheel 26 in the second massage wheel frame 1201 also rolls on both sides of the user's thighs with the second massage wheel frame 1201, thereby achieving a massage effect on the thighs.

[0030] The present invention avoids the traditional method of using insulation bags to keep joints warm, which limits the patient's joint activities. It adopts the method of installing flexible thermal pads at the joint activities, which not only satisfies the need to keep the joints warm, but also provides a certain amount of movement space for the joints. The movable mechanism of the present invention can drive the calf to bend when driven by the patient's own arms, thereby exercising the joints. The thigh massage mechanism of the present invention will work synchronously with the movable mechanism to massage both sides of the patient's thigh. The back massage mechanism of the present invention can massage the patient's back when driven by the patient's own arms. The calf massage mechanism of the present invention works synchronously with the movable mechanism to massage the back of the patient's calf, thereby increasing the comfort of use.
