Description

Rehabilitation training bed for stroke patients

technical field

The invention relates to the technical field of medical devices, in particular to a rehabilitation training bed for stroke patients.

Background technique

Stroke, also known as stroke, refers to the loss of brain function that develops rapidly due to blockage of blood supply to the brain. 80% of strokes are ischemic strokes, which are caused by insufficient blood supply to the brain, leading to brain tissue dysfunction and necrosis. With the development of my country's economy, the pace of life is getting faster and faster, people's life pressure is increasing, and the number of stroke patients is also increasing. When stroke patients enter the rehabilitation period, most of them will leave sequelae such as hemiplegia, muscle spasm and atrophy, and aphasia to varying degrees. Among them, hemiplegia is the most common limb disorder, causing great pain to themselves and their families.

In order to avoid limb muscle spasms and complete paralysis, it is necessary to regularly perform functional positioning exercises for the patient's limbs clinically. At present, the existing technology mainly relies on manual positioning of the patient's limbs, which is very troublesome and time-consuming. strenuous. Especially for some more serious stroke patients, due to the sequelae caused by brain damage, they cannot sit up and stand up by themselves. During the rehabilitation period, specialized medical staff or family members need to manually lift the patient up and sit up again and again. Moreover, this kind of exercise needs to be repeated many times a day, and the labor intensity is high, which adds great work difficulty and burden to the medical staff, and it is not easy for the patient to persist. It is for this reason that some patients cannot perform functional position placement exercises and joint activities in the best activity period in time, resulting in joint stiffness, muscle atrophy and other adverse consequences, which seriously affect the patient's ability to take care of themselves in life and bring psychological problems. pressure. Therefore, it is of great significance to set up a rehabilitation training bed for stroke patients with a high degree of automation and good training effect for the rehabilitation and treatment of stroke patients' motor dysfunction.

Contents of the invention

The technical problem to be solved by the present invention is to provide a rehabilitation training bed for stroke patients, which can automatically perform rehabilitation training for stroke patients sitting up and lying down under the action of program control without excessive manual assistance.

When the rehabilitation training bed for stroke patients of the present invention is used for specific use, let the patient lie flat on the treatment bed first, make the neck correspond to the position of the neck bracket set on the support plate, and put the head on the fixed headgear Inside, if necessary, the goggles on the headgear can be rotated and fixed to cover the patient's eyes. Afterwards, an external airbag is used to inflate the inflatable chamber of the neck brace through the air guide tube detachably connected with the inflation chamber, so that the upper surface of the neck brace It forms an inwardly concave arc shape, and the higher parts on both sides can comfortably and stably cover and fix the patient's entire head and neck; the surface of the fixed headgear forms a hollow cover-shaped cap, Comfortably and stably cover and fix the head of the patient except the face. After inflating, the head and neck brace is evenly provided with a plurality of massage protrusions on the outer surface that can be in contact with the patient's head and neck. Through the inflation and deflation process of the inflatable cavity in the head and neck brace, the patient's head and neck blood vessels and nerves can be stimulated to a certain extent. Massage stimulates to help it recover function quickly.

When the sit-up training of the upper trunk is to be performed, the device can be activated by the control mechanism, and the rehabilitation training bed can perform sit-up and lie-down training for the patient for a period of time according to the program setting.

When it is necessary to perform training on changing the functional position of the patient's upper limb, the patient's forearm is firmly fixed with a clamp by means of the elastic connection belt provided on the forearm fixing plate. Then, through the control mechanism to start the device, the power mechanism in the functional position placement device can drive the slider to move back and forth on its corresponding track according to the program setting, and then perform forward and backward flexion and extension and left and right swings on the upper affected limb of the patient. The functional position is changed, and the anti-spasmodic function recovery training is performed.
