Description

Technical Field

[0001] The present invention specifically relates to a medical nerve and muscle stimulator, belonging to the technical field of medical devices. Background Art

[0002] A medical nerve and muscle stimulator is a medical device that stimulates nerve or muscle tissues through electrical pulses to achieve the purposes of treatment, rehabilitation, or diagnosis. It can be used in aspects such as rehabilitation treatment, muscle function recovery, and pain management. A nerve and muscle stimulator usually consists of one or more electrodes and a controller. The electrodes are pasted or placed on the skin to transmit current into the nerve and muscle tissues of the body. The controller can set the intensity, frequency, and duration of the current to achieve the treatment purpose.

[0003] After retrieval, in the patent with the Chinese patent publication number CN220513277U, a nerve and muscle stimulator is disclosed, including: a housing with a micro-current circuit board inside, and a circuit strip with a plurality of electrode pads connected to the bottom. A connection mechanism is provided between the housing and the circuit strip; the connection mechanism includes wing plates provided on both sides of the housing. A clamping post is clamped inside the wing plate. A connecting block is provided at the lower part of the clamping post. The bottom of the connecting block is fixed to the top of the circuit strip; a metal contact rod is provided at the output end of the circuit strip. The metal contact rod penetrates through the side walls of the housing and the wing plate and contacts a contact point provided on the clamping post. Although in this patent, the circuit strip can be directly laid flat under the housing through the connection mechanism, making the coverage range of the circuit more comprehensive, the micro-current circuit board can transmit the micro-current to the electrode pads on the circuit strip through the metal contact rod and the contact point to perform micro-electrical stimulation on the nerves and muscles of the user. The setting of the connection mechanism not only prevents the circuit strip from detaching from the housing but also facilitates the replacement of the circuit strip.

[0004] However, during the use of this stimulator, problems such as poor contact between the electrode pads and the user's skin are likely to occur, such as loosening of the electrode pads, drying of the gel, or obstruction by hair, resulting in unstable current or ineffective stimulation. When the wearer moves (such as walking or raising the hand), the electrode pads may detach from the skin, interfering with the continuity of treatment, easily delaying a lot of time for adjustment, and reducing the use efficiency of the stimulator. Summary of the Invention

[0005] The purpose of the present invention is to provide a medical nerve and muscle stimulator aiming at the deficiencies of the prior art, so as to achieve the dynamic fitting of the electrode pads to the skin of the wearer, effectively reduce the probability of problems such as poor contact between the electrode pads and the skin of the wearer, and effectively improve the use efficiency of the stimulator body.

[0006] A medical nerve and muscle stimulator, comprising a stimulator body and a connecting base. An electrode patch is provided at the bottom end of the connecting base, and a conductive gel is adhesively attached to the lower surface of the electrode patch. A strap is disposed through the inside of the connecting base, and a protective pad is provided on the lower surface of the strap. The protective pad is made of rubber and is in a circular shape. A spring is disposed inside the connecting base, and the top end of the spring is connected to the lower surface of the protective pad.

[0007] With the above technical solution, by using the first magic tape and the second magic tape to adhere, the adjustable tightness of the strap can be achieved, adapting to different limb circumferences (such as the arm and thigh), meeting the needs of different body types, improving versatility. When the strap is tightened, during the tightening process, the rubber protective pad can squeeze the spring and deform. The spring enables the electrode patch to adaptively fit with the limb movement, avoiding detachment, realizing the dynamic fitting of the electrode patch to the skin of the wearer, effectively reducing the probability of problems such as poor contact between the electrode patch and the skin of the wearer, effectively improving the usage efficiency of the stimulator body. The protective sleeve made of silicone rubber with good elasticity can be sleeved outside the stimulator body. The protective sleeve and the convex columns can increase the friction of holding the stimulator body, preventing the stimulator body from slipping during operation. The protective sleeve and the convex columns can increase the anti-drop performance of the stimulator body. The multiple groups of oval ventilation holes opened inside the strap are used to provide ventilation for the skin of the wearer, avoiding the skin of the wearer and the contact surface of the strap from being stuffy during long-term wearing, preventing sweat accumulation, and being suitable for long-term rehabilitation use.

[0008] Preferably, a display screen is provided at the display end of the stimulator body, and control buttons are provided at the regulation end of the stimulator body.

[0009] Preferably, a protective sleeve is provided outside the stimulator body, and multiple groups of convex columns are provided on the outside of the protective sleeve. Both the protective sleeve and the convex columns are made of silicone rubber.

[0010] Preferably, an adjustment switch is provided at the control end of the stimulator body, and a first through groove is penetrated through the inside of the protective sleeve, and the adjustment switch movably penetrates through the inside of the first through groove.

[0011] Preferably, two second through grooves are penetrated through the inside of the protective sleeve, and two connection ports are opened at the connection end of the stimulator body. The inside of the two connection ports communicates and is located behind the two second through grooves.

[0012] Preferably, connection wires are connected inside the two connection ports, and the other ends of the connection wires are electrically connected to the connecting base.

[0013] Preferably, a microcurrent circuit board and a metal contact rod are provided inside the connecting base for delivering microcurrent into the electrode patch.

[0014] Preferably, a plurality of groups of oval ventilation holes are penetrated and opened inside the strap. One end of the strap is provided with a first magic tape, and the other end of the strap is provided with a second magic tape, and the second magic tape can be adhered to the first magic tape.

[0015] Beneficial effects:

[0016] 1. By providing components such as springs, the conductive gel can be attached to the skin of the wearer through the conductive gel, enhancing conductivity, reducing skin impedance, and improving the stimulation efficiency. By using the adhesion of the first magic tape and the second magic tape, the strap can be tightened. During the tightening process of the strap, the rubber - material protection pad can squeeze the spring and deform. The spring enables the electrode patch to adaptively fit with the limb movement, avoiding detachment, realizing the dynamic fit of the electrode patch to the skin of the wearer, effectively reducing the probability of problems such as poor contact between the electrode patch and the skin of the wearer, and effectively improving the use efficiency of the stimulator body.

[0017] 2. By providing components such as a protective cover and convex columns, the elastic silicone - rubber - material protective cover can be sleeved outside the stimulator body.
