Description

Technical Field

[0001] This utility model relates to the field of knee and ankle antispasm meridian acupoint stimulation technology, specifically to a wearable knee and ankle antispasm meridian acupoint stimulation device. Background Technology

[0002] Patients with stroke, paralysis, and traumatic brain injury often have long rehabilitation cycles and require prolonged bed rest. After rehabilitation, they frequently experience limb stiffness, difficulty moving, foot cramps, and a tendency to fall. Stimulating acupoints on the knees and ankles can prevent foot cramps and improve foot drop.

[0003] In existing technologies, wearable stimulation devices are often used to stimulate the anti-spasm meridian acupoints of the knee and ankle. The stimulation device mainly consists of electrode pads, a controller, and an elastic band. Medical staff attach the electrode pads to the patient's knee and ankle, and the elastic band is fixed to the electrode pads. The elastic band is then wrapped around the patient's knee and ankle for adhesion and fixation. Then, the controller controls the electrode pads to deliver different levels of stimulation to the anti-spasm meridian acupoints of the patient's knee and ankle, which can effectively relieve spasms and improve rehabilitation efficacy.

[0004] However, the length of the elastic band is fixed. When the patient's knee and ankle are too wide, it is difficult and laborious for medical staff to attach the elastic band to the patient's knee and ankle. The patient's knee and ankle are subjected to a lot of pressure from the elastic band, and the electrode pads are also subjected to a lot of pressure from the elastic band, which leads to poor operation of the electrode pads and thus affects the effectiveness of the stimulation device. Utility Model Content

[0005] The purpose of this invention is to provide a wearable knee and ankle anti-spasm meridian acupoint stimulation device to solve the technical problem that in the prior art, the length of the elastic band is fixed. When the patient's knee and ankle are too wide, it is troublesome and laborious for medical staff to attach the elastic band to the patient's knee and ankle. The patient's knee and ankle are subjected to great pressure from the elastic band, and the electrode pads are also subjected to great pressure from the elastic band, which leads to poor operation of the electrode pads and thus affects the effectiveness of the stimulation device.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A wearable knee and ankle anti-spasm meridian acupoint stimulation device includes:

[0008] A base plate, the top of which is provided with a support plate, the base plate and the support plate are connected together, and an electrode sheet is fixedly connected to the inner wall of the support plate;

[0009] An elastic band, one end of which is fixedly connected to a support plate, and the other end of which is fitted with a locking seat, which is fixedly connected to an electrode plate;

[0010] A locking assembly is fixedly connected to a locking seat and is also connected to an electrode plate.

[0011] As a further embodiment of this utility model: a threaded rod is provided between the base plate and the support plate, an adjustment seat is fixedly connected to the side end of the support plate, the adjustment seat has a threaded hole in the longitudinal direction, the threaded rod is threadedly connected to the inner wall of the threaded hole, and the bottom end of the threaded rod is engaged with the base plate.

[0012] As a further embodiment of this utility model: a rotating seat is fixedly connected to the bottom end of the threaded rod, and a rotating groove is opened inside the base plate. The rotating seat is snapped into the rotating groove and rotatably connected to the inner wall of the rotating groove.

[0013] As a further embodiment of this utility model: the support plate has a plurality of heat dissipation holes through it, and the heat dissipation holes cooperate with the electrode sheet.

[0014] As a further embodiment of this utility model: the locking seat is provided with a sliding groove, the electrode plate is slidably connected to the inner wall of the sliding groove, and the locking assembly includes: a connecting pipe and a bolt, the connecting pipe is provided with a locking hole through the locking seat in the axial direction, the locking hole is connected to the sliding groove, and the inner wall of the locking hole is threadedly connected to the bolt.

[0015] As a further embodiment of this utility model: a plurality of protrusions are fixedly connected to the side end of the bolt, the bolt is abutted against the electrode plate, the protrusions are hemispherical in shape, and the protrusions cooperate with the electrode plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. Medical staff place the base plate on the patient's sole for fit, then attach the electrode pads to the patient's knee and ankle. Next, an elastic band is wrapped around the patient's knee and ankle, with the other end of the band passed through a locking seat. The elastic band, in conjunction with the locking seat, secures the support plate to the patient's knee and ankle, thus fixing the electrode pads in place. The locking seat is flexible and has sufficient length to accommodate different patients' knees and ankles, preventing excessive pressure from the elastic band on patients with overly wide knees and ankles, thereby improving the effectiveness of the stimulation device.

[0018] 2. After the elastic band is wrapped around and fitted to the patient's knee and ankle, the locking assembly of the locking seat is used to lock and fix the elastic band, ensuring that the elastic band will not loosen from the patient's knee and ankle. This ensures that the electrode pads are fully fitted and fixed to the patient's knee and ankle. When the stimulation device is to be removed, the medical staff controls the locking assembly to open, releasing the locking and fixing of the elastic band, and thus the stimulation device can be removed from the patient's knee and ankle.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-7 As shown, a wearable knee and ankle anti-spasm meridian acupoint stimulation device includes: a base plate 1, an elastic band 2, and a locking assembly.

[0030] The base plate 1 has a support plate 6 on top, and the base plate 1 is connected to the support plate 6. Electrode 3 is fixedly connected to the inner wall of the support plate 6. One end of the elastic band 2 is fixedly connected to the support plate 6, and the other end of the elastic band 2 is connected to the locking seat 7. The locking seat 7 is fixedly connected to the electrode 3. Medical staff place the base plate 1 on the patient's foot for fit, then fit the electrode 3 to the patient's knee and ankle, and then wrap the elastic band 2 around the patient's knee and ankle. The other end of the elastic band 2 is passed through the locking seat 7. The elastic band 2 fits and fixes the support plate 6 to the patient's knee and ankle by cooperating with the locking seat 7, thereby fixing the electrode 3 to the patient's knee and ankle. The locking seat 7 is plastic and can be reserved with sufficient length to ensure that the locking seat 7 can be fitted and fixed to the knee and ankle of different patients, avoiding the phenomenon that the elastic band 2 will cause excessive pressure on the patient due to the patient's knee and ankle being too wide, thus improving the effect of the stimulation device.

[0031] The locking assembly is fixedly connected to the locking seat 7 and the locking assembly is also connected to the electrode pad 3. After the elastic band 2 is wrapped around the patient's knee and ankle, the locking assembly fixed by the locking seat 7 locks the elastic band 2 to ensure that the elastic band 2 will not loosen from the patient's knee and ankle, thus ensuring that the electrode pad 3 is fully attached and fixed to the patient's knee and ankle. When the stimulation device is to be removed, the medical staff controls the locking assembly to open, release the locking of the elastic band 2, and then remove the stimulation device from the patient's knee and ankle.

[0032] In some specific implementations, a threaded rod 4 is provided between the base plate 1 and the support plate 6. An adjusting seat 5 is fixedly connected to the side end of the support plate 6. The adjusting seat 5 has a threaded hole 10 in the longitudinal direction. The threaded rod 4 is threadedly connected to the inner wall of the threaded hole 10. The bottom end of the threaded rod 4 is connected to the base plate 1. Medical staff can move the position of the electrode pad 3 according to the knee and ankle of different patients. By rotating the threaded rod 4, the threaded rod 4 drives the adjusting seat 5 to move through the threaded connection with the threaded hole 10. The adjusting seat 5 drives the support plate 6 to adjust its height, thereby moving the electrode pad 3 to the anti-spasm meridian acupoint of the knee and ankle that the patient needs to stimulate. When rotating the threaded rod 4, medical staff can control the support plate 6 to align the electrode pad 3 on the support plate 6 with the anti-spasm meridian acupoint of the patient's knee and ankle. The support plate 6 can rotate on the threaded rod 4 through the adjusting seat 5, which further improves the applicability of the electrode pad 3. When the threaded rod 4 stops rotating, the threaded rod 4 transfers the supporting effect of the base plate 1 to the support plate 6.

[0033] In some specific implementations, a rotating seat 12 is fixedly connected to the bottom end of the threaded rod 4, and a rotating groove 13 is provided inside the base plate 1. The rotating seat 12 is engaged in the rotating groove 13 and rotatably connected to the inner wall of the rotating groove 13. When the threaded rod 4 rotates, the threaded rod 4 carries the rotating seat 12 to rotate in the rotating groove 13. The engagement of the rotating seat 12 and the rotating groove 13 ensures that the threaded rod 4 will not become loose on the base plate 1.

[0034] In some specific implementations, the support plate 6 has several heat dissipation holes 16 through it. The heat dissipation holes 16 cooperate with the electrode plate 3. When the electrode plate 3 is running for a long time, it will generate heat. The heat dissipation holes 16 can dissipate the heat and prevent the heat generated by the electrode plate 3 from accumulating in the anti-spasm meridian acupoints of the patient's knee and ankle, which would affect the patient's use effect.

[0035] In some specific embodiments, the locking seat 7 has a through groove 11, and the electrode plate 3 is slidably connected to the inner wall of the groove 11. The locking assembly includes a connecting tube 8 and a bolt 9. The connecting tube 8 has an axially formed locking hole 14 that penetrates the locking seat 7. The locking hole 14 communicates with the groove 11. The inner wall of the locking hole 14 is threadedly connected to the bolt 9. Several protrusions 15 are fixedly connected to the side end of the bolt 9. The bolt 9 abuts against the electrode plate 3. The protrusions 15 are hemispherical in shape and cooperate with the electrode plate 3. When the elastic band 2 wraps around the patient's knee and ankle... The other end of the elastic band 2 passes through the groove 11. When the elastic band 2 is fully in contact with the patient's knee and ankle, the bolt 9 is rotated. The bolt 9 rotates through the threaded connection with the locking hole 14. When the protrusion 15 on the bolt 9 abuts against the electrode plate 3, the protrusion 15 abuts against the electrode plate 3 and rotates, thereby deforming the electrode plate 3. When the bolt 9 abuts against the electrode plate 3, the rotation of the bolt 9 is stopped. The bolt 9 locks and fixes the electrode plate 3 by abutting against the electrode plate 3. The protrusion 15 further improves the locking effect of the bolt 9 on the electrode plate 3.

[0036] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
