Examples

The embodiment of the application provides an electrical stimulation device 100 for treating sarcopenia, adopts pulse current and mechanical vibration to stimulate muscles, and has a good treatment effect on the sarcopenia patients. The structure of the electrostimulation device 100 for treating sarcopenia is explained in detail below with reference to fig. 1 to 4.

As shown in fig. 1, 2, the electrical stimulation apparatus 100 for treating sarcopenia includes an outer case 10, a plurality of electrode bodies 20, a pulse current generator (not shown in fig. 1, 2), and a plurality of mechanical vibration apparatuses 30.

The interior of the housing 10 forms a treatment passage 11 for the legs of the human body. The electrode body 20 is mounted in the case 10 and is adapted to be in contact with the leg portions. The pulsed current generator is used to send pulsed current to the electrode body 20 to stimulate contraction of the leg muscles. Each electrode body 20 is connected to the housing 10 via a mechanical vibration device 30, and the mechanical vibration device 30 is used to drive the electrode bodies 20 to vibrate.

As shown in fig. 3, in actual use, the legs of the human body are positioned in the treatment channel 11, the electrode bodies 20 are in contact with the skin surface of the legs, and the pulse current generated by the pulse current generator is conducted to the legs through the electrode bodies 20, thereby stimulating muscle contraction and promoting blood circulation; meanwhile, the mechanical vibration device 30 drives the electrode body 20 to vibrate to stimulate the muscle to vibrate and promote the blood circulation, so as to achieve the purpose of treatment. The device stimulates muscles by adopting a pulse current and mechanical vibration mode, and has good treatment effect.

Illustratively, as shown in FIG. 1, the housing 10 is cylindrical and the treatment channel 11 inside the housing 10 is conical. The two axial ends of the housing 10 are respectively a first end 12 and a second end 13, and the two ends of the treatment channel 11 respectively penetrate through the first end 12 and the second end 13. Wherein the opening of the treatment channel 11 at the first end 12 is larger than the opening of the treatment channel 11 at the second end 13.

Further, the electrical stimulation apparatus 100 for treating sarcopenia further comprises a first leg clamp 40 and a second leg clamp 50. A first leg clamp 40 and a second leg clamp 50 are attached to the first end 12 and the second end 13, respectively, the first leg clamp 40 and the second leg clamp 50 each being adapted to clamp a leg.

As shown in fig. 3, after the leg of the human body enters the therapeutic treatment passage 11, the thigh of the human body can be clamped by the first leg clamping device 40, and the calf of the human body can be clamped by the second leg clamping device 50, so that the shell 10 is firmly fixed on the outer side of the leg of the human body, and the current and vibration stimulation treatment can be conveniently carried out on the leg muscle.

Optionally, the first leg rest 40 comprises an elastic collar 41 and an outer sleeve 42, the elastic collar 41 being provided at the first end 12. The outer sleeve 42 is screwed to the housing 10, and the outer sleeve 42 has an inner tapered surface 421.

When the elastic collar 41 rotates relative to the housing 10, the inner tapered surface 421 can press the elastic collar 41 against the leg portion.

In practice, after the legs of the human body enter the treatment passage 11, the thighs will be located in the elastic sleeve 41, and during the process of tightening the outer sleeve 42, the outer sleeve 42 will move axially, so that the inner conical surface 421 of the outer sleeve 42 presses the elastic sleeve 41 to deform, so that the elastic sleeve presses the legs. The first leg unit 40 of this construction can easily clamp the leg. In addition, the elastic collar 41 has elasticity and has good protection effect on the leg.

Wherein the elastic collar 41 is located within the outer sleeve 42. The elastic collar 41 may be made of elastic plastic, elastic sponge, etc.

Furthermore, the outer sleeve 42 is screwed to the outside of the housing 10, i.e. the outer sleeve 42 is provided with an internal thread and the housing 10 is provided with an external thread matching the internal thread of the outer sleeve 42.

The elastic collar 41 is provided at the first end 12 of the housing 10, and both the elastic collar 41 and the housing 10 may be connected together or may be separate structures.

In this embodiment, the elastic collar 41 and the housing 10 are separate structures, that is, the elastic collar 41 and the housing 10 are only in contact relationship and are not connected together. This structure makes the elastic collar 41 more likely to be deformed by being shrunk inward as a whole after receiving the pressing force of the inner conical surface 421.

Although the elastic collar 41 and the housing 10 are not directly connected, since the elastic collar 41 is located in the outer sleeve 42 and the inner conical surface 421 of the outer sleeve 42 has a limiting effect on the elastic collar 41, the elastic collar 41 is always limited in the outer sleeve 42 when the outer sleeve 42 is not separated from the housing 10.

In other embodiments, the first leg-gripping means 40 may have other configurations, for example, the first leg-gripping means 40 comprises an elastic loop 41 and a binding-rope, the elastic loop 41 is connected to the first end 12 of the shell 10, and the elastic loop 41 is pressed against the leg by the binding-rope.

Of course, the second leg unit 50 may have various configurations. In this embodiment, the second leg unit 50 has the same structure as the first leg unit 40, and will not be described herein.

The mechanical vibration device 30 is used for driving the electrode body 20 to vibrate, and the mechanical vibration device 30 can be in various structures.

The positive electrode body 22 and the negative electrode body 23 are electrically connected to the pulse current generator, and the positive electrode body 22 and the negative electrode body 23 are each adapted to be in contact with the leg portion. The mechanical vibration device 30 further includes a top-pressing member 34, and the top-pressing member 34 is movably disposed on the movable seat 32.

The driving device 33 has two functions, namely, driving the movable seat 32 to swing back and forth, and driving the ejection member 34 to move back and forth. In the process of driving the ejection member 34 to reciprocate by the driving device 33, the ejection member 34 intermittently ejects the elastic deformation portion 211 from the ejection hole 322, so that the elastic deformation portion 211 intermittently ejects the leg, which can be regarded as the ejection member 34 driving the elastic deformation portion 211 to vibrate in one direction, to stimulate leg muscles. In addition, when the elastic deformation portion 211 is vibrated by the knock-out member 34, the elastic deformation portion 211 is elastically deformed, and the positive electrode body 22 and the negative electrode body 23 are reciprocally moved, and the positive electrode body 22 and the negative electrode body 23 are considered to be vibrated in the other direction.

In other embodiments, the moving direction of the knock-out member 34 and the arrangement direction of the slide hole 321 may be at other angles, such as an obtuse angle or an acute angle.

The insulating elastic sheet 21 has elasticity and insulating ability, and may be made of elastic plastic, elastic rubber, or the like. The positive electrode body 22 and the negative electrode body 23 are both conductors, and may be made of metal such as copper, iron, aluminum, or the like.

After the pulse current enters the leg, the muscle of the leg can be contracted.

Alternatively, the elastic deformation portion 211 is arc-shaped, and the elastic deformation portion 211 is caught in the through hole 322.

The elastic deformation portion 211 has a circular arc structure, so that the elastic deformation portion 211 has good deformation and deformation recovery capabilities. The elastic deformation portion 211 is clamped in the through hole 322, and the elastic deformation portion 211 has a limiting function, so that the electrode body 20 is not easy to slide out of the sliding hole 321.

As shown in fig. 5, the movable seat 32 includes a base plate 323 and a connecting plate 324, the connecting plate 324 is arranged perpendicular to the base plate 323, the connecting plate 324 is connected to the upper surface of the base plate 323, and the base plate 323 extends upward along the height direction of the connecting plate 324.

The knock-out member 34 is movably disposed in the coupling hole 325; both the first sheet body 212 and the second sheet body 213 of the electrode body 20 are movably disposed in the slide hole 321. During the elastic deformation of the elastic deformation portion 211 under the action of the top-pressing member 34, the first sheet 212 and the second sheet 213 will move in the sliding hole 321, so as to drive the positive electrode 22 and the negative electrode 23 to move.

The connecting base 31 has a contact portion 312, when the driving element 332 drives the eccentric 331 to rotate, the eccentric 331 can contact the contact portion 312 to make the movable base 32 swing back and forth relative to the connecting base 31, and the eccentric 331 can make the knock-out member 34 move back and forth relative to the movable base 32.

When the driving element 332 drives the eccentric 331 to rotate, the eccentric 331 will drive the movable seat 32 to swing back and forth, so that the electrode body 20 vibrates following the movable seat 32, and at the same time, the eccentric 331 will drive the ram 34 to move back and forth, so that the elastic deformation portion 211 vibrates vertically, and the positive electrode body 22 and the negative electrode body 23 vibrate laterally. The eccentric wheel 331 rotates to realize the reciprocating swing of the movable seat 32 relative to the connecting seat 31 and the reciprocating movement of the ejection piece 34 relative to the movable seat 32, and the structure is simple.

Wherein, a plurality of guide rods 311 are arranged on the connecting seat 31, a plurality of guide holes 14 are arranged on the housing 10, and one guide rod 311 is correspondingly inserted in one guide hole 14 to realize the stable movement of the connecting seat 31.

The guide rods 311 may be two, three, four, etc. Illustratively, the number of the guide rods 311 is two.

Illustratively, the driving unit 35 includes a driving motor 351 and a lead screw 352, the driving motor 351 is fixed to the housing 10, the lead screw 352 is connected to an output shaft of the driving motor 351, and the connecting seat 31 is screwed to an outer side of the lead screw 352. The driving motor 351 drives the screw rod 352 to rotate in the positive direction, so that the electrode body 20 can be gradually close to the leg; the driving motor 351 drives the screw rod 352 to rotate reversely, so that the electrode body 20 can be gradually away from the leg.

In the process of stimulating the muscle of the leg of the human body by the pulse current, the pulse current generated by the pulse current generator is increased, the heart rate of the human body is increased, and therefore the pulse current is not suitable to be too large.

In some embodiments of the present application, as shown in fig. 6, the electrical stimulation apparatus 100 for treating sarcopenia further comprises a heart rate sensor and a controller. The heart rate sensor is used for detecting heart rate signals of a human body. The controller is used for controlling the size of the pulse current sent by the pulse current generator according to the heart rate signal so that the heart rate of the human body represented by the heart rate signal does not exceed a preset value.

When the heart rate sensor detects that the heart rate of the human body is about to reach a preset value, the controller controls the pulse current generator to reduce the pulse current and ensure that the heart rate of the human body is not over the preset value.

Wherein, the pulse current generator and the heartbeat sensor are both electrically connected with the controller. The controller can be a single chip microcomputer or a PLC controller.

Illustratively, the preset value of the heart rate is 100 times/minute.

In addition, a pressure sensor electrically connected to a controller may be provided on both the positive electrode body 22 and the negative electrode body 23 of the electrode body 20, and the driving motor 351 of the driving unit 35 may be electrically connected to the controller. When the driving motor 351 is operated and the electrode body 20 is gradually brought close to the leg portion, the controller controls the driving motor 351 to stop operating when the pressure value detected by the pressure sensor reaches a preset pressure value.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
