Description

A wearable airbag device for upper limb rehabilitation training and protection

technical field

The invention relates to the technical field of medical and health equipment, in particular to a wearable airbag device for upper limb rehabilitation training and protection.

Background technique

According to statistics, there are more than 2 million new stroke patients in China every year. On average, one person has a stroke every 12 seconds, and one person dies every 21 seconds. Stroke has become the number one cause of death in China. The acute stage of stroke is several days to 2 weeks after the onset of stroke. The affected limbs of stroke patients cannot actively move or move very weakly, and the muscle tone is low. Early rehabilitation can help patients remodel their nerves and build confidence in rehabilitation.

Stroke patients are prone to arm dislocation and other injuries during rehabilitation training due to insufficient muscle strength during the flaccid stage. However, in the existing upper limb rehabilitation equipment, there is no equipment specially designed to provide shoulder joint protection for early stroke patients during rehabilitation training. At the same time, the current airbag structure can only perform simple massage for patients with varicose veins, and is not suitable for preventing upper limb joint swelling and muscle atrophy in stroke patients. In addition, the wearing structure of this type of airbag is unreasonable, and an external pipe is used to connect the airbag cover, which is inconvenient to use.

Among them, the arm part 2 of the airbag body is composed of four airbag covers connected in sequence, from the shoulder joint part 1 to the hand part 3 are the first airbag cover 21, the second airbag cover 22, the third airbag cover 23 and the fourth airbag cover 24. The air chambers 25 of each air bag cover are independent of each other, and the inflation and deflation port 4 is composed of four airway openings 41, and the four airway openings 41 respectively pass through mutually independent embedded airways (the first embedded airway 26, the second Two built-in air passages 27, the third built-in air passage 28 and the fourth built-in air passage 29) communicate with the air chambers 25 of four airbag covers, and each built-in air passage is connected with the air chamber of the airbag body. 25 inner walls are bonded and connected (the built-in airway can be made of the same material as the airbag body), as shown in Figures 3-4, the inner diameter of the built-in airway matches the size of the air chamber 25 of the corresponding airbag cover, so that When inflating, the air chambers of each airbag cover can be filled at the same time, and the pressure in the air chambers of each airbag cover during the restart process can be guaranteed to be consistent. For example, in this embodiment, the air chamber volumes of the first airbag cover 21 and the fourth airbag cover 24 Greater than the air chamber volume of the second air bag cover 22 and the third air bag cover 23, so the diameter (gas channel diameter) of the first built-in air channel 26 and the fourth built-in air channel 29 is larger than the second built-in air channel 27 and the diameter of the third built-in air channel 28.

The air passage port 41 of this embodiment adopts a valve core type inflation and deflation structure, and a thimble is provided inside the air passage port 41, and a connecting thread is provided outside the air passage port 41, and the air supply mechanism includes an air pump 10, an air delivery pipe 11 and a sealed connection pipe connected in sequence 12. An electromagnetic valve 13 is provided on the air delivery pipe 11, and the connecting thread of the sealing connecting pipe 12 and the airway port 41 is detachably connected, as shown in FIG. 5 .

In this embodiment, the outer surface of the elbow joint of the arm part 2 of the airbag body is provided with an organ-like cover 9 for providing support for the elbow joint of the human body while ensuring the degree of freedom of the elbow joint of the human body.

In this embodiment, the inner surface of the elbow joint of the arm 2 of the airbag body is attached with an elbow Velcro 51, and the support rod 5 is detachably connected to the inner surface of the elbow joint of the arm 2 of the airbag body through the elbow Velcro 51.

The end of the hand part 3 of the airbag body in this embodiment is provided with an opening.

The application of the wearable airbag device for upper limb rehabilitation training and protection is used for human upper limb rehabilitation training, which has an active training mode and a passive training mode;

In the active training mode, the human body wears the device, the air supply mechanism inflates the airbag body to the set pressure, and then disconnects, so that the device is used to protect the human shoulder joint during rehabilitation training;

In the passive training mode, the human body wears the device, and the air supply mechanism circulates and gradually inflates and deflates the airbag body, so that the device can be used to promote blood circulation in the upper limbs of the human body during rehabilitation training.

When in use, the patient first wears the arm and hand, then uses the underarm adjustment plate and the connecting belt to adjust the tightness of the wearer, adjusts the Velcro on the wearing part, passes through the armpit of the left shoulder and adjusts the tightness to complete the wearer. When using rehabilitation training modules such as nursing beds for active training, the active training mode can be selected on the controller, and the airway port and the air delivery tube can be threaded with a sealed connecting tube. At this time, the electromagnetic valve is in the open state, the valves of the airway opening and the air delivery pipe are opened, the air pump starts to work, and the output gas flows through the electromagnetic valve and the air delivery pipe to the airway opening set on the surface of the air bag, and then through the airway opening. In the built-in airway inside the airbag. Each embedded airway is independent of each other and does not affect each other. The surface of each airbag cover in contact with the human body is equipped with a thin-film pressure sensor. During the inflation process, the pressure formed by the airbag on the surface of the upper limb increases continuously. When the pressure reaches the predetermined value of the sensor, the electromagnetic valve corresponding to the corresponding airbag cover is closed, and the air pump stops working. After inflating, the airbag forms a good protection for the patient's shoulders and upper limbs. At this time, the sealed connecting tube can be unscrewed, the air delivery tube can be removed, and the airbag can be combined with the handle of other rehabilitation training robots through the connection structure set on the hand for rehabilitation training. . At this time, the patient has 3 degrees of freedom of the shoulder, elbow, and wrist joints, which can train the entire upper limb and effectively prevent upper limb dislocation.

In the passive training mode, install the support rod on the inner side of the elbow of the arm, connect the airway opening and the air tube, and select the passive mode. The airbag can control the gas flow of each airbag cover by adjusting the opening and closing of the solenoid valve and the inflation and deflation of a single air pump, so as to realize the cycle inflation and deflation of four airbag covers and control the inflation and deflation of a single airbag cover. Pinch the muscles to achieve the effect of preventing muscle atrophy of the upper limbs and promoting blood circulation.

The above descriptions of the embodiments are for those of ordinary skill in the art to understand and use the invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described here to other embodiments without creative effort. Therefore, the present invention is not limited to the above-mentioned embodiments. Improvements and modifications made by those skilled in the art according to the disclosure of the present invention without departing from the scope of the present invention should fall within the protection scope of the present invention.
