Description

Technical Field

[0001] The utility model relates to the technical field of devices for relieving cramps, and particularly relates to a device for relieving cramps. Background Art

[0002] Cramps are a common symptom, mainly manifested as involuntary muscle contractions, resulting in pain and discomfort. Cramps may be related to various reasons, such as fatigue, mineral deficiency, nervous system diseases, etc. And cramps in the hands and feet are a common symptom clinically. When a patient has a cramp, usually methods such as hot compress, massage, and applying force in the opposite direction are needed to quickly relieve it. However, these relief methods generally require the help of others. In some scenarios where it is impossible to obtain help from others in time, it is very difficult for the patient to relieve the symptoms by themselves. For example, patients undergoing hemodialysis are very likely to have leg cramps during dialysis. At this time, the patient cannot take measures to relieve the symptoms by themselves. When medical staff cannot provide help immediately, the patient will feel very uncomfortable and unable to relieve the cramp symptoms.

[0003] Currently, the main ways to relieve cramps on the market are mainly external application (applying drugs externally) and oral medications. Oral medications have a slow effect, and externally applied drugs have a slightly faster effect but usually also require the help of others to apply, and neither can achieve the effect of quickly relieving symptoms and reducing the workload of medical staff or caregivers.

[0041] Application scenario of an exemplary embodiment:

[0042] As Figures 1 to 7 shown, place the device for relieving cramp symptoms disclosed by the present utility model at the end of the hospital bed, and the patient can control the device for relieving cramp symptoms through the controller. Before the patient undergoes hemodialysis, the patient needs to wear a disposable sock or shoe cover first. According to the patient's needs, place a medicine bag containing Chinese herbal medicine in the cloth bag 57. Then, the patient lies flat on the hospital bed, and the medical staff assist the patient to place the calf in the leg placing channel 55 surrounded by the auxiliary component 5, and use the second fixing strap 36 to fix the auxiliary component 5, and then place the patient's calf together with the auxiliary component 5 in the first accommodating cavity 11 of the first fixing housing 1. At the same time, the medical staff also assist the patient to place the sole of the foot in the second accommodating cavity 21 of the second fixing housing 2, and use the first fixing strap 34 to fix the sole of the foot of the patient in the second accommodating cavity 21. Before the patient's calf has cramp symptoms, the patient can control the heating body 53 to apply hot compress to the calf through the controller, and can control whether the heating body 53 performs heating and control the heating temperature or heating intensity. The patient can also control the massage airbag 521 on the airbag layer 52 to massage the calf through the controller, and can control whether to perform massage and adjust the massage intensity. Through the cooperation of hot compress and massage, the occurrence of cramp symptoms in the patient can be prevented.

[0043] When the patient's calf has cramp symptoms, the patient can also control the stepping motor 31 to work through the controller. The stepping motor 31 drives the second fixing housing 2 to rotate around the connecting shaft 33 through the gearbox 4. The second fixing housing 2 rotates around the connecting shaft 33 in the direction close to the patient's head to apply a reverse force to the sole of the foot to quickly relieve the cramp symptoms. At this time, hot compress and massage can also be used in combination to assist in relieving the cramp symptoms. After the patient's cramp symptoms are relieved, the patient can control the second fixing housing 2 to rotate to the normal position through the controller to ensure the comfort of the foot.

[0044] When a patient has a foot cramp, without their assistance, the patient can operate the device for relieving cramp symptoms disclosed by the present utility model by themselves, which can massage and apply hot compress to the calf, and can further enhance the effect of relieving cramp by cooperating with a hot compress and a medicine bag, and can also be used for preventing cramp. The device for relieving cramp symptoms disclosed by the present utility model can also quickly relieve cramp symptoms by applying a reverse force. The device for relieving cramp symptoms disclosed by the present utility model can not only help the patient relieve cramp symptoms by themselves, but also reduce the workload of medical staff.
