Description

Rehabilitation device after vitrectomy of the inner eye

technical field

The invention belongs to the technical field of medical rehabilitation devices, and in particular relates to a rehabilitation device for patients after vitrectomy.

Background technique

After vitrectomy, it is necessary to maintain a face-down position to rely on the upward force of silicone oil or gas to support and press the detached retina, so as to reset the retina and seal the tear. If the patient does not strictly maintain the body position and head position, not only is it not conducive to the reattachment of the detached retina, but it may also cause complications such as cataract and secondary glaucoma. Generally speaking, after silicone oil or gas filling, it is required to maintain a face-down position. When facing down, the mandible should be as close to the sternum as possible. This position should be maintained for about 16 hours a day. No matter sitting, prone, or walking, it is necessary to keep facing down. It lasts for 1 to 2 weeks. Since the patient needs to maintain a face-down position for a long time, resulting in a decline in self-care ability and limited movement, many patients experience postoperative gait instability, which increases their risk of falls; patients generally need to be supported by others to complete independent tasks. Walking, due to prolonged bed rest, most patients have constipation.

In view of the above problems, it is necessary to develop a rehabilitation device for patients after vitrectomy, which can walk automatically, and can perform 360-degree imaging of the forward scene, so that patients can walk or go out safely independently, which can improve the quality of life to a certain extent. The patient's self-care ability and exercise ability make him feel happy, thereby accelerating the patient's rapid recovery.

As an improvement of this embodiment, it also includes a manipulation system 5. The manipulation system includes a control chip 51 and a control button 52. The control chip is electrically connected to the telescopic mechanism, the multi-stage electric push rod, the display and the control button. The control button is connected to the telescopic mechanism, The multi-stage electric push rods are electrically connected. The height and width values of the scooter are displayed on the display. When adjustment is required, the patient sends the adjusted height and width values through the control button. After receiving the instruction, the control chip sends specific adjustment parameters to the telescopic mechanism and the multi-stage electric push rod. , The multi-stage electric push rod works, and the result is displayed on the monitor, and the patient observes it in real time. After the adjustment is in place, the adjustment step is completed. In this embodiment, for convenience, the control button is fixed under the display through a soft belt, which is convenient for patients to use and will not be lost. Meanwhile, in this embodiment, the control chip 51 and the control button 52 are integrated into one body.

As an improvement of this embodiment, the central area of the elastic cushion is provided with a through hole 32, and the display is connected with the elastic cushion through a foldable flexible rod 44, and is connected by a ball hinge 45 at the joint, so that the display is connected between the flexible rod and the ball hinge. Under the action, the spatial position can be adjusted, and after the flexible rod is rotated and bent, the display can be located in the lower area of the through hole. When the patient stays in the car for a long time, he can get off the car, turn off the drive motor, and make the scooter move forward under the push of the patient. The patient leans his head down on the elastic cushion, and his sight passes through the through hole and falls on the monitor. On the screen, the function of the scooter is enhanced by observing the obstacles in progress or moving dangerous objects through the display. The flexible rod 44 has been widely used in the prior art, such as lamp support, microphone support and other fields, and will not be described here.

As an improvement of this embodiment, a covering cushion 33 is provided above the through hole, and a cushion placement hole 34 is provided on the elastic seat cushion. When using the present invention as a substitute for walking, the covering cushion is placed in the cushion placement hole. When it is necessary to push it manually, the covering cushion is taken out. On the one hand, it is used as a scooter to cover the cushion to make sitting more comfortable; When used as a rickshaw, remove the covering cushion to avoid direct contact with the human face and reduce the spread of bacteria. At the same time, the device has multiple functions, so that patients can have more choices.

As an improvement of this embodiment, the shell of the left base or the shell of the right base is provided with a cushion storage hole 19, which can accommodate and store the covered cushion. Avoid dropping and also convenient for storage.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be carried out Modifications or equivalent replacements, without departing from the spirit and scope of the technical solution, should be included in the scope of the claims of the present invention.
