Description

Technical Field

[0001] The present invention relates to the technical field of medical care devices, and particularly to a prone frame for retinal repositioning of fundus disease patients. Background Art

[0002] Medical care devices refer to instruments, equipment, appliances, and other similar or related items directly or indirectly used on the human body. These devices are mainly used for the diagnosis, prevention, monitoring, treatment, or alleviation of diseases, as well as the inspection, replacement, adjustment, or support of physiological structures or physiological processes. They also include in vitro diagnostic reagents for examining samples from the human body, providing information for medical or diagnostic purposes. To ensure the physical health of patients, medical care devices need to undergo strict disinfection before and during use to prevent bacteria from infecting the patients' wounds.

[0003] After retrieval, the invention patent with the Chinese patent number CN117547422A discloses a prone device for retinal repositioning after eye surgery. Compared with the prior art, the invention patent with the Chinese patent number CN117547422A includes a body support assembly and a head support assembly. The bed board includes a fixed plate, a first sliding plate, and a second sliding plate arranged in sequence from the bed tail to the head of the bed. The first sliding plate and the second sliding plate are rotatably connected, and a support member for supporting the back of the first sliding plate is also rotatably provided on the bed frame; the head support assembly includes a base, a lifting assembly is provided on the base, and a support ring is provided at the top of the lifting assembly. This enables the patient to maintain a prone position while sleeping, which is beneficial for postoperative recovery. The first sliding plate and the second sliding plate can slide and then flip during the day. The first sliding plate is supported to be in an inclined state, making the first sliding plate become a backrest and the second sliding plate become a seat plate. The legs of the patient are placed at the slid-out interval, and at this time, the patient can sit upright and also place the face on the support ring.

[0004] However, in the actual use process of the above device, due to the relatively fixed design of the support ring, it is not easy to support according to the head circumference of the patient, resulting in limitations in the use process of the above device. At the same time, the adjustable range of the body support assembly is relatively small. Since fundus disease patients need to keep their heads down and maintain a relatively fixed state, when the patient lies prone on the hospital bed for a long time, the body posture is not adjusted for a long time, which is likely to cause muscle fatigue and other situations. Therefore, a prone frame for retinal repositioning of fundus disease patients is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages of limitations in the use process and the inability to adjust the prone posture of patients for a long time in the prior art, and to propose a prone frame for retinal repositioning of fundus disease patients.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Retinal repositioning prone frame for fundus disease patients, including a support frame. A first electric telescopic rod is installed at the bottom of the support frame.

A second electric telescopic rod is installed on the body support plate. The telescopic movement of the second electric telescopic rod drives the driving column to move. The movement of the driving column drives the turning shaft and the connecting shaft to flip. The turning shaft and the connecting shaft drive the first cross brace and the second cross brace to drive the plurality of body support plates arranged thereon to rise or fall. The first electric telescopic rod drives the fourth cross brace to flip through telescopic movement, driving the angle change between the body support plate and the support frame to achieve lifting and lowering;

[0008] A head support ring is fixedly connected to the outside of the support frame. A head support assembly is arranged on the support frame. The head support assembly includes a plurality of adjusting sector plates rotatably arranged inside the head support ring, a support airbag jointly installed by the plurality of adjusting sector plates, a driven gear installed on the adjusting sector plate, a worm rotatably arranged inside the head support ring, a first gear and a second gear rotatably arranged on the inner side of the head support ring. The worm drives the first gear to rotate self - rotatably, driving the plurality of second gears to rotate synchronously.

The multiple armrest braces 5 are fixedly connected to an armrest frame 4 in common. The head support ring 6 is used to support the patient's head, and the armrest frame 4 is used to limit the prone area of the patient.

[0041] Two third cross braces 13 are fixedly connected to the support frame 1 in common. Two second cross braces 12 and a third support column 15 are rotatably connected to the support frame 1 in common. A connecting buckle 16 is symmetrically and rotatably connected between the first cross brace 11 and the second cross brace 12. The first cross brace 11, the second cross brace 12, the third cross brace 13 and the fourth cross brace 14 are all fixedly connected to the body support plate 2. The first cross brace 11, the second cross brace 12, the third cross brace 13 and the fourth cross brace 14 are respectively used to adjust the prone positions of the patient's lower limbs and upper limbs.
