Description

Technical Field

[0001] The invention relates to the field of therapeutic device technology, specifically a therapeutic device for spastic muscles. Background Technology

[0002] The purpose of a spastic muscle therapy device is generally to treat spastic paralysis and relieve spasms. A low-frequency spastic muscle therapy device is a type of low-frequency pulse physical therapy device, typically used to treat spastic paralysis. The low-frequency pulsed current directly stimulates neuromuscular tissue, causing muscle excitation and contraction. It can alternately output two sets of pulses with adjustable pulse width and frequency, simultaneously stimulating the patient's spastic and antagonistic muscles. Through interactive stimulation, the spastic muscles relax, thereby improving the function of the affected area and achieving the goal of rehabilitation.

[0003] When using a muscle spasm treatment device, a suction cup and electrodes are typically used together. While helping to relax muscles and relieve spasms, the suction cup generates negative pressure, which can increase blood circulation and oxygen supply, promoting the recovery and rehabilitation of muscle tissue. However, when using the existing suction cups, the patient's muscle groups may harden due to electrical stimulation, muscles may tremble, and the influence of hair and the human skeleton itself may cause loosening, resulting in incomplete electrode contact and reduced treatment effectiveness. For safety reasons, if the suction cup falls off, the treatment device needs to be powered off and the suction cup needs to be reset. This not only interrupts the treatment but also increases the workload of medical staff.

[0004] Therefore, we propose a muscle spasm treatment device. Summary of the Invention

[0005] The purpose of this invention is to provide a treatment device for spastic muscles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the invention provides the following technical solution: a spastic muscle treatment device, comprising a treatment device body, a tube connected to the front end of the treatment device body, and a suction cup connected to the end of the tube away from the treatment device body;

[0007] The adsorption component is located at the connection between the tube body and the suction cup, and it is adsorbed onto the patient's muscle surface using a negative pressure method.

[0008] An alarm component is located on the surface of the suction cup. The alarm component triggers the suction to increase the suction force, and the suction cup can be re-attached to the patient's skin surface when it falls off.

[0009] Preferably, the alarm component includes a socket 30, which is opened on the outer surface of the suction cup. An alarm is fixedly connected inside the socket 30. A trigger groove is opened on the lower outer surface of the alarm. A trigger plate is slidably connected inside the trigger groove. A push rod is fixedly connected to the upper end of the trigger plate. A switch is fixedly connected to the upper end of the inner surface of the trigger groove at a position corresponding to the push rod.

[0010] Preferably, the alarm assembly further includes a vent hole, which is opened at the upper end of the inner surface of the trigger groove and passes through the alarm. A reset spring is fixedly connected between the upper end of the inner surface of the trigger groove and the upper outer surface of the trigger plate, and a blocking block is fixedly connected to the lower edge of the inner surface of the trigger groove.

[0011] Preferably, the adsorption assembly includes an air inlet, which is opened on the outer surface of the tube body one near the end. An electrode is fixedly connected to the end of the tube body one away from the main body of the therapeutic device. The electrode is located inside the suction cup. The tube body one penetrates the suction cup and is fixedly connected to the suction cup. A tube body two is sleeved inside the tube body one. The tube body two is electrically connected to the electrode. The diameter of the tube body one is larger than the diameter of the tube body two.

[0012] Preferably, the adsorption assembly further includes an eccentric hole, through which a tube passes, and a diaphragm is provided between the tube and the eccentric hole. The tube consists of a rigid tube and a flexible tube. The rigid tube is located inside the eccentric hole and is fixedly connected to the diaphragm. An annular groove is formed on the outer surface of the rigid tube. A rotating ring is rotatably connected to the lower outer surface of the inner surface of the annular groove via a bearing. A fan blade is fixedly connected to the inner surface of the rotating ring. The upper end of the rotating ring is rotatably connected to the upper end of the inner surface of the annular groove via a bearing. The upper end of the rigid tube is fixedly connected to the flexible tube. A speed reduction device is provided on the outer surface of the rotating ring. A push rod is fixedly connected to the outer surface of the speed reduction device away from the rigid tube. The push rod contacts the annular inner surface of the eccentric hole.

[0013] Preferably, the speed reduction device includes gears, which are rotatably connected to the rigid tube body via a rotating shaft. Teeth are fixedly connected to the annular outer surface of the rotating ring, and the gears mesh with the teeth. There are three sets of gears, all of which are rotatably connected to the rotating ring. A toothed ring meshes with the annular outer surface of the gears, and the annular outer surface of the toothed ring is fixedly connected to the push rod.

[0014] Preferably, the push rod has an L-shaped structure design, and the annular outer surface of the push rod is rotatably connected to a roller through a bearing. The annular outer surface of the roller contacts the annular inner surface of the eccentric hole.

[0015] Preferably, tube body three is fitted outside tube body two. The diameter of tube body three is larger than the diameter of tube body two and smaller than the diameter of tube body one. Electrorheological fluid is injected into the gap between tube body three and tube body two. A space for flowing gas is formed between tube body three and tube body two. Connecting blocks are connected between tube body one, tube body two and the inner surface of tube body one.

[0016] Preferably, an annular embedding groove is formed on the inner surface of the eccentric hole, and an embedding plate is fixedly connected to the corresponding position of the annular outer surface of the rigid tube body and the embedding groove. Both the embedding plate and the embedding groove are made of rubber.

[0017] The invention has at least the following beneficial effects:

[0018] By setting an alarm component, an alarm will sound when the suction cup slips off. At the same time, the main body of the treatment device will be controlled by switch one to increase the suction force of tube one and quickly reset the suction cup. If increasing the suction force of tube one alone cannot reset the suction cup, the surface of tube one will rotate through a wind-driven ring, which will drive a deceleration device to reduce the speed of the push rod and increase the torque. The push rod will contact the eccentric hole, forcing the suction cup to change position and then try to re-adhere in conjunction with the suction force. Through the cooperation of the above structures, medical staff can be quickly alerted. At the same time, the suction cup has the ability to automatically adsorb, which can reduce the workload of medical staff and maintain the continuity of treatment. Attached Figure Description

[0032] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0033] Please see Figure 1-12 The invention provides a technical solution:

[0034] Example 1,

[0035] A spastic muscle treatment device includes a treatment device body 1, a tube 20 connected to the front end of the treatment device body 1, and a suction cup 10 connected to the end of the tube 20 away from the treatment device body 1.

[0036] The adsorption component 2 is located at the connection between the tube body 20 and the suction cup 10. It is adsorbed onto the patient's muscle surface using a negative pressure method. The negative pressure fixation method can increase blood circulation and oxygen supply, promote the rehabilitation and recovery of muscle tissue, and thus improve the treatment effect on spastic muscles.

[0037] Alarm component 3 is located on the surface of suction cup 10. Alarm component 3 triggers adsorption to increase suction force, so that suction cup 10 can be re-adsorbed onto the patient's skin surface when it falls off. Alarm component 3 will sound an alarm when there is a loss of pressure inside suction cup 10 or when suction cup 10 falls off. At the same time, switch 35 controls adsorption component 2 to generate greater suction force inside tube 20, forcing suction cup 10 to automatically reset, maintaining the continuity of treatment, and reducing the workload of medical staff.

[0038] The alarm component 3 includes a socket 30, which is opened on the outer surface of the suction cup 10. An alarm 31 is fixedly connected inside the socket 30. A trigger groove 32 is opened on the lower outer surface of the alarm 31. A trigger plate 33 is slidably connected inside the trigger groove 32. A push rod 37 is fixedly connected to the upper end of the trigger plate 33. A switch 35 is fixedly connected to the upper end of the inner surface of the trigger groove 32 at a position corresponding to the push rod 44.

[0039] When installing the suction cup 10, the user first pinches the suction cup 10 to deform it, and then attaches it to the patient's muscle surface. At this time, the suction cup 10's own elasticity seals the covered area. Then, air is drawn out of the suction cup 10 through the tube 20, causing the air pressure inside the suction cup 10 to drop. The deformable electrode 24 of the suction cup 10 comes into contact with the patient's muscle, forcing the trigger plate 33 to move downward along the trigger groove 32. The trigger plate 33 drives the top rod 37 to disengage from the switch 35. In this scheme, the trigger plate 33 and the trigger groove 32 remain sealed. When the internal pressure of the suction cup 10 is lost, the air pressure inside the suction cup 10 is restored. At this time, the trigger plate 33 moves upward along the trigger groove 32 until the top rod 37 touches the switch 35. At this time, the alarm 31 sounds an alarm to remind medical staff that the suction cup 10 has fallen off.

[0040] The alarm component 3 also includes a vent 36, which is located on the upper part of the inner surface of the trigger groove 32 and extends through the alarm 31. A return spring 34 is fixedly connected between the upper part of the inner surface of the trigger groove 32 and the upper outer surface of the trigger plate 33. A blocking block 38 is fixedly connected to the lower edge of the inner surface of the trigger groove 32. Unlike the above scheme, the return spring 34 is used to replace the counter-pull force generated by the seal between the trigger plate 33 and the trigger groove 32. The vent 36 can discharge the air between the trigger groove 32 and the trigger plate 33 to ensure the stability of the alarm component 3. The design of the blocking block 38 prevents the trigger plate 33 from detaching from the trigger groove 32.

[0041] The adsorption component 2 includes an air inlet 23, which is opened on the outer surface of the tube body 20 near the end. An electrode 24 is fixedly connected to the end of the tube body 20 away from the treatment device body 1. The electrode 24 is located inside the suction cup 10. The tube body 20 passes through the suction cup 10 and is fixedly connected to the suction cup 10. A tube body 22 is sleeved inside the tube body 20. The tube body 22 is electrically connected to the electrode 24. The diameter of the tube body 20 is larger than the diameter of the tube body 22.

[0042] When the suction cup 10 detaches or the internal pressure of the suction cup 10 is lost, the push rod 37 of the alarm component 3 will contact the switch 35, which will increase the suction force of the tube 20 of the treatment device body 1. The air inside the suction cup 10 will enter the tube 20 through the air intake hole 23, and the suction cup 10 will be reset by negative pressure. When the internal pressure of the suction cup 10 is restored, the trigger plate 33 and the push rod 37 will move downward and disengage from the switch 35. Through the cooperation of the adsorption component 2 and the alarm component 3, an alarm will be sounded when the suction cup 10 detaches. At the same time, the suction cup 10 can reset itself and clear the alarm, maintaining the continuity of treatment and preventing the treatment from being interrupted due to the suction cup 10 falling off.

[0043] According to the above embodiments, Embodiment Two

[0044] The adsorption assembly 2 also includes an eccentric hole 25, through which the tube body 20 passes. A diaphragm 26 is provided between the tube body 20 and the eccentric hole 25. The tube body 20 is composed of a rigid tube body 201 and a flexible tube body 202. The rigid tube body 201 is located inside the eccentric hole 25 and is fixedly connected to the diaphragm 26. An annular groove 46 is provided on the outer surface of the annular tube body 201. A rotating ring 40 is rotatably connected to the lower end of the inner surface of the annular groove 46 via a bearing. A fan blade 41 is fixedly connected to the inner surface of the rotating ring 40. The upper end of the rotating ring 40 is rotatably connected to the upper end of the inner surface of the annular groove 46 via a bearing. The upper end of the rigid tube body 201 is fixedly connected to the flexible tube body 202. A speed reduction device 4 is provided on the outer surface of the rotating ring 40. A push rod 44 is fixedly connected to the outer surface of the speed reduction device 4 away from the rigid tube body 201. The push rod 44 is in contact with the annular inner surface of the eccentric hole 25.

[0045] When the gap between the suction cup 10 and the skin is too large due to factors such as the patient's skin shape or body hair, simply increasing the suction force of the tube 20 is insufficient to achieve the repositioning effect of the suction cup 10. As the suction force inside the tube 20 increases, the rotating ring 40 rotates inside the rigid tube 201 via the fan blade 41, driving the reduction device 4. This causes the push rod 44 to slowly contact the inner wall of the eccentric hole 25 with the center point of the rotating ring 40 as the fulcrum, forcing the electrode 24 or the suction cup 10 to change position. The diaphragm 26 covers the surface of the eccentric hole 25, preventing air from escaping from the suction cup 10. When the body leaks out, the electrode 24 changes position, which can change the center of gravity of the entire suction cup 10, allowing the suction cup 10 to automatically find a suitable adsorption position. At the same time, the change in the position of the electrode 24 can also treat the surrounding muscles. When the gap between the suction cup 10 and the skin is small enough, it attempts to adsorb again under the suction force generated by the tube 20. Through the above scheme, the adsorption component 2 can automatically reset the suction cup 10, which improves the continuity of treatment. At the same time, it also eliminates the need for medical staff to fix the suction cup 10 after it falls, reducing the workload of medical staff.

[0046] The speed reduction device 4 includes a gear 42, which is rotatably connected to the rigid tube 201 via a rotating shaft. The outer annular surface of the rotating ring 40 is fixedly connected with teeth, and the gear 42 meshes with the teeth. There are three sets of gears 42, all of which are rotatably connected to the rotating ring 40. The outer annular surface of the gear 42 is meshed with a gear ring 43, and the outer annular surface of the gear ring 43 is fixedly connected to the push rod 44. By reducing the drag, the rotational speed of the push rod 44 is reduced, thereby increasing the torque generated by the push rod 44, making it easier to push the electrode 24 or the suction cup 10 to move, so that the suction cup 10 can be reset more quickly after being dislodged.

[0047] The push rod 44 has an L-shaped structure design. The annular outer surface of the push rod 44 is rotatably connected to the roller 45 through the bearing. The annular outer surface of the roller 45 contacts the annular inner surface of the eccentric hole 25, reducing the friction between the push rod 44 and the eccentric hole 25 and ensuring the effective operation of the speed reduction device 4.

[0048] Tube body 22 is fitted with tube body 3 21. The diameter of tube body 3 21 is larger than that of tube body 22, and the diameter of tube body 3 21 is smaller than that of tube body 1 20. Electrorheological fluid is injected into the gap between tube body 3 21 and tube body 22. A space for flowing gas is formed between tube body 3 21 and the tube body. Connecting blocks 27 are connected between tube body 1 20, tube body 22, and the inner surface of the tube body. The connecting blocks 27 can support tube body 1 20, tube body 22, and tube body 3 21.

[0049] If the position of electrode 24 cannot be changed, at the instant switch 35 is turned on, the electrorheological fluid inside tube 21 and tube 22 will be energized and become solid, thereby restricting the movement of the entire tube 20. By restricting the movement of tube 20, the movement of electrode 24 is prevented. The thrust generated by push rod 44 acts inside the eccentric hole 25, and suction cup 10 moves in the opposite direction along push rod 44 to find a suitable position for re-adhesion. Through the above structure, the position of suction cup 10 can be adjusted without changing the contact position between electrode 24 and skin, ensuring the accuracy of muscle treatment.

[0050] According to the above embodiments, in Embodiment 3,

[0051] An annular embedding groove 28 is formed on the inner surface of the eccentric hole 25. An embedding plate 29 is fixedly connected to the annular outer surface of the rigid tube 201 at the corresponding position of the embedding groove 28. Both the embedding plate 29 and the embedding groove 28 are made of rubber. In the above embodiment, the diaphragm 26 blocks the air inside and outside the suction cup 10. The diaphragm 26 has a large deformation, which is not conducive to the rapid adsorption of the suction cup 10. The embedding plate 29 is inserted into the embedding groove 28 instead of the diaphragm 26. The diameter of the embedding groove 28 is larger than the diameter of the embedding plate 29, and the diameter of the eccentric hole 25 is smaller than the radius of the embedding plate 29. This ensures that the embedding plate 29 is always located inside the embedding groove 28 when the suction cup 10 is moving. By reducing the deformation of the diaphragm 26, the reaction speed of the suction cup 10's secondary adsorption is increased, further maintaining the continuity of treatment.
