Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-4, a muscle stimulation device for thigh comprises an electrode patch 1, a conductive sleeve i 2 is arranged in the middle of one side of the front surface of the electrode patch 1, a fixing buckle 3 is fixedly mounted on one side of the outer surface of the conductive sleeve i 2, the bottom end of the fixing buckle 3 is fixedly connected with the middle of the top end of the electrode patch 1, an annular air bag retainer ring 4 is arranged on the inner wall of the fixing buckle 3, the outer wall of the annular air bag retainer ring 4 is clamped with the inner wall of the fixing buckle 3, a limiting plate 5 is fixedly mounted on one side of the annular air bag retainer ring 4, a conductive connector 6 is movably sleeved on the inner wall of the limiting plate 5, one end of the conductive connector 6 penetrates through the inner part of the annular air bag retainer ring 4 and extends to the inner wall of the conductive sleeve i 2, the outer surface of the conductive connector 6 is movably sleeved with the inner part of the annular air bag retainer ring 4, and the outer surface of one end of the conductive connector 6 is contacted with the inner wall of the conductive sleeve i 2, a fixed handle rod 7 is fixedly arranged at one side of the limiting plate 5, a movable block 8 is fixedly arranged at the other end of the conductive joint 6, the outer wall of the movable block 8 is contacted with the inner wall of the fixed handle rod 7, self-feeding springs 9 are fixedly arranged at the upper end and the lower end of one side of the movable block 8, one ends of the two self-feeding springs 9 are respectively and fixedly connected with the top and the bottom of one side of the inner cavity of the fixed handle rod 7, a conductive rod 10 is fixedly arranged at the middle part of one side of the movable block 8, a conductive sleeve II 11 is arranged at the middle part of one side of the inner cavity of the fixed handle rod 7, the two groups of self-feeding springs 9 are arranged, so that the upper side and the lower side of the movable block 8 are uniformly stressed, when the conductive joint 6 is accidentally dropped, the movable block 8 can be timely pushed to move forwards, the connection between the conductive rod 10 and the conductive sleeve II 11 is broken, and the inclined blocking of the movable block 8 in the inner cavity of the fixed handle rod 7 caused by nonuniform stress is effectively avoided, and then lead to its unable timely disconnection low frequency pulse current signal, and cause the problem of burn to patient's skin, the effectual reliability and the security that improve this muscle stimulation device in the use.

Among this technical scheme, the inner wall of fixed buckle 3 is even is equipped with a set of dog, and the length of every dog all is greater than annular gasbag retaining ring 4's thickness 1mm, to the setting of dog and length, both can effectually ensure fastness and the stability of annular gasbag retaining ring 4 when the chucking, can prevent that the device from taking place the phenomenon that annular gasbag retaining ring 4 drops automatically at the in-process that uses, can dismantle the washing to its quick again, stability is good during the use, high reliability, easy dismounting.

In the technical scheme, the initial length of the self-feeding spring 9 is more than 3mm of the sum of the lengths of the conducting rod 10 and the conducting sleeve II 11, and the maximum elastic force of the self-feeding spring 9 is smaller than the clamping force between the fixed buckle 3 and the annular air bag retainer ring 4, the initial length and the maximum elastic force of the self-feeding spring 9 are set, so that the self-feeding spring 9 has enough elastic force to bounce off the conductive rod 10, the low-frequency pulse current signal of the conductive joint 6 is cut off in time, meanwhile, the fixing handle rod 7 can not be reversely pushed due to overlarge elasticity of the self-feeding spring 9 in the clamping process of the annular air bag retainer ring 4, so that the annular air bag retainer ring 4 is separated from the stop block on the fixing buckle 3, further, the conductive connector 6 and the conductive sleeve I2 are separated, so that the muscle of the patient cannot be effectively stimulated and treated, and the treatment time and the treatment effect of the patient are delayed.

In this technical scheme, the degree of depth of conductive sleeve I2 inner chamber is less than the at least 5mm of length that conductive contact 6 stretches out annular gasbag retaining ring 4, to the setting between the degree of depth of conductive sleeve I2 and the conductive contact 6 stretch out length, can ensure that conductive contact 6 has sufficient length to reverse the conductive contact 6 when inserting conductive sleeve I2 inner chamber bottom, make contact take place between conducting rod 10 and conductive sleeve II 11, put through the low frequency pulse current on the conductive contact 6, can not lead to contact failure between conducting rod 10 and conductive sleeve II 11 because the length of conductive contact 6 takes place for the short excessively, even the problem of unable contact.

Among this technical scheme, the slotted hole has been seted up to the inside of conductive sleeve II 11, and the slotted hole on conductive sleeve II 11 and conducting rod between the phase-match, to the setting of slotted hole and position on conductive sleeve II 11 for contact that can be stable between conducting rod 10 and the conductive sleeve II 11, even at rotatory in-process can not take place contact failure's problem yet, further improved the stability and the reliability of this equipment in the course of the work.

The use method and the working principle of the embodiment are as follows:

when the electrode patch is used, firstly, the electrode patch 1 is fixed on thigh muscles of a patient needing electrical stimulation, then the conductive connector 6 is inserted into the conductive sleeve I2, the limiting plate 5 is pushed inwards with force, the stop block on the fixing buckle 3 can press the annular air bag check ring 4 and enable the annular air bag check ring to generate elastic deformation, then the annular air bag check ring 4 with elastic deformation can penetrate through the stop block on the fixing buckle 3 and be clamped with the stop block, meanwhile, as the depth of the inner cavity of the conductive sleeve I2 is smaller than the extension length of the conductive connector 6, when the conductive connector 6 moves to the bottom of the inner cavity of the conductive sleeve I2, the conductive connector 6 can be pressed to move towards the right side to compress the self-feeding spring 9, the conductive rod 10 is communicated with the slotted hole of the inner cavity of the conductive sleeve II 11, when the stop block on the fixing buckle 3 is clamped by the annular air bag check ring 4, the conductive rod 10 and the conductive sleeve II 11 can also be stably communicated with a circuit, then, the low-frequency pulse current signal is started, so that the electric stimulation can be carried out on the muscle on the thigh of the patient;

when the in-process that uses drops because of the accident is automatic between current-conducting sleeve I2 and current-conducting terminal 6, at first under the spring action from sending spring 9, can automatic drive movable block 8 and conducting rod 10 to the left side removal, make conducting rod 10 break away from current-conducting sleeve II 11, thereby cut off the electricity between current-conducting terminal 6 and the low frequency pulse current and be connected, make current-conducting terminal 6 uncharged, even take place direct contact with patient's skin, also can not cause the burn to patient's skin, there is not the problem of potential safety hazard, even take place medical malpractice.
