A migraine treatment supporting device, comprising: a device body (100). Provided on the device body (100) are a U-shaped frame (2), a connecting portion (1), and a handle (3). The connecting portion (1) is provided on a top end of the U-shaped frame (2). The handle (3) is provided at a bottom end of the U-shaped frame (2). The U-shaped frame (2) is internally provided with a micro power source (22) and a micro-controller (23). A micro-vibrator (21) is disposed on an inner wall surface of the U-shaped frame (2). The micro-vibrator (21) is controlled by the micro-controller (23) to provide a vibration massage. The micro-vibrator (21) forms a hemispherical protrusion on a side facing a human head. A magnetic tip (211) is disposed on the hemispherical protrusion. The migraine treatment supporting device is easy and convenient to use, and improves an effect of magnetic therapy to promote the physical health of a user.
A: A headache therapeutic instrument, comprising a wearing frame matched with a human head (8), a massage and percutaneous administration device (3), a liquid medicine infusion tube (4), a liquid medicine infusion device (5), and a liquid medicine storage box (6). The wearing frame is provided with at least one acupuncture point positioning hole (12, 23) with respect to the human head (8); the massage and percutaneous administration device (3) is mounted on the wearing frame and is provided opposite to the acupuncture point positioning holes (12, 23); the liquid medicine infusion device (5) conveys a medicine in the liquid medicine storage box (6) to the massage and percutaneous administration device (3) by means of the liquid medicine infusion tube (4); the massage and percutaneous administration device (3) is capable of simultaneously carrying out administration and massage on the corresponding acupuncture points. The headache therapeutic instrument, which is different from the conventional medicine administration and injection, infuses a medicine into human acupuncture points by means of the skin in a percutaneous treatment mode, thereby overcoming the defects of oral administration and injection, and massage is carried out while the medicine is infused, thereby effectively relieving migraine of a patient.
B: A cap for adjuvant therapy on a patient with cerebrovascular and cardiovascular disease, comprising a cap body (100) having a crown (1), a peripheral edge (2), and a brim (3). The crown (1) and the peripheral edge (2) form an integrally-connected structure. Magnets are provided on an outer surface of an inner layer of the peripheral edge (2). Heating pieces (12), a temperature controlled switch (13), an electric massaging pad (14), and a controller (15) are provided on the crown (1). The temperature controlled switch (13) is connected to the heating pieces (12) by means of wires. The electric massaging pad (14) is connected to the controller (15) by means of a wire. The temperature controlled switch (13) controls the heating pieces (12) to heat the cap body (100). The heating pieces (12) are provided at the inner layer of the crown (1). The electric massaging pad (14) massages head acupoints of a patient with cerebrovascular and cardiovascular disease according to the control of the controller (15). The cap is easy to use and can improve the physical health condition of patients with cerebrovascular and cardiovascular disease.
C: A limb dysfunction rehabilitation device (100), comprising a vertical pole (1), a base (2), and a seat (3). The vertical pole (1) and the seat (3) are fixed onto the base (2), and a rotary disc (4) is provided on the base (2) between the vertical pole (1) and the seat (3). A movable arm (10) is mounted on the top end of the vertical pole (1); one end of the movable arm (10) is connected to the top end of the vertical pole (1), and the other end is provided with a near infrared lamp (11); the near infrared lamp (11) is electrically connected to a power supply (22) by means of a switch button (21). The seat (3) is provided with an arm magnetic therapy part (5) and a backrest (6); the arm magnetic therapy part (5) comprises an arm sleeve (51) and elongated permanent magnets (52); when the power supply (22) is electrified, the elongated permanent magnets (52) induce magnetism to yield a magnetic therapy effect on an arm of a patient. The top end of the backrest (6) is provided with a headrest (7); a massage vibrator (72) is provided inside the headrest (7); the massage vibrator (72) is electrically connected to the power supply (22) by means of the switch button (21), so as to carry out vibration massage on head of the patient when the power supply (22) is electrified. The device (100) can perform safe and effectual rehabilitation training treatment on patients suffering from limb dysfunction, without producing any toxic and side effect of medicine, and thus is easy to operate, economical and practical.
D: A neck massager for health management, comprising a U-shaped support (100) and further comprising a massage tip (1), a controller (2), a heat emitting mesh (3), a draw string (5), and a cord lock (6). The heat emitting mesh (3) is provided on the massage tip (1). A temperature sensor (4) detects a surface temperature of the U-shaped support (100) and sends a detected temperature value to the controller (2). The controller (2) is used to control a heat emission of the heat emitting mesh (3) for heating the massage tip (1). The controller also controls the massage tip (1) to massage a neck of a user. The draw string (5) comprises a first draw string (51) and a second draw string (52). The cord lock (6) is disposed on the first draw string (51) and the second draw string (52) and is used to fix the first draw string (51) and the second draw string (52). When the first draw string (51) and the second draw string (52) are loosened, the cord lock (6) is able to move along the first draw string (51) and the second draw string (52). The neck massager provides a warming effect during massaging, thereby accelerating blood circulation in the neck area, providing effective alleviation of discomfort experienced by neck muscles, and improving user comfort.
