Detailed Description

The following description is made with reference to the accompanying drawings and a specific embodiment.

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

The mobile prone position support described in this embodiment is used for post-operative head or torso support. For example, in the rehabilitation stage after eye surgery, when the rehabilitation patient is not lying prone in bed, the forehead of the rehabilitation patient is supported; or after cardiac surgery, some patients have too high postoperative foot blood pressure, and after sitting down, the feet need to be lifted up by using the bracket. Therefore, the prone position support is mainly used for eye surgery, but the support is not limited to be used by rehabilitation patients after eye surgery.

See fig. 1-6. In this embodiment, the movable prone position support comprises a base 100, and the base 100 supports a foot 110. In this embodiment, the supporting legs 100 are 3 arc-shaped supporting rods arranged in a radial manner, and mainly function to keep the stand stable in an upright state. A lifting rod for adjusting the height of the bracket is installed above the base 100. The supporting seat is arranged at the top of the lifting rod and used for supporting the head, the trunk or the affected limb of a rehabilitation patient.

The support seat comprises a substrate 310, the substrate 310 is detachably connected with the inner rod 220, a flexible pad 230 is mounted on the substrate 310, and the flexible pad 230 completely covers or completely wraps the substrate 310. The flexible pad 230 is of a cuboid structure, the height of the cuboid is 5-10 cm, the width of the cuboid is 10-15 cm, and the length of the cuboid is 20-30 cm. The width of the flexible pad 230 is slightly larger than the width of the forehead, and the thickness of the flexible pad 230 should ensure the comfort of the forehead; the length of the flexible cushion 230 can ensure that the forehead is rested safely and effectively. The flexible cushion 230 is a cloth-covered asbestos cushion, and may be a replaceable water bag or an inflatable bag. The flexible pad 230 is detachably connected to the substrate 310 for cleaning and replacement.

The lifting rod is composed of an outer cylinder 210, an inner rod 220 and a nut 230, and the lifting rod is adjustable in length and can be fixed on a preset length. The inner rod 220 is assembled in the outer cylinder 210, and the outer cylinder 210 is matched with the nut 230 through conical threads. The inner rod 220 is slidably engaged with the outer barrel 210, and the length of the inner rod 220 is equal to the length of the outer barrel 210.

The nut 230 is used for fastening the inner rod 220 and the outer cylinder 210, and adjusting the sliding fit relation and the fastening fit relation between the inner rod 220 and the outer cylinder 210.

In one embodiment, the nut 230 has a grab bar 231 removably mounted thereto. The two grab bars 231 are symmetrically disposed at both sides of the nut 230. The grab rail 231 is convenient for the rehabilitation patient to place hands or arms during the use of the support, and on the other hand, the nut can be rotated through the grab rail 231, and the nut 230 can be rotated more easily by delaying the rotation moment.

Referring to fig. 6, the upper end of the outer cylinder 210 is an external thread end, the external thread end is longitudinally provided with a plurality of notches 212, and the notches 212 are used for slightly deforming the top end of the outer cylinder 210 when the nut 230 is fastened, so that the inner wall of the top end of the outer cylinder 210 is attached to the inner rod 220 more tightly, and the friction force is larger.

In a further embodiment, in order to further improve the positioning performance of the inner rod 220, positioning teeth 213 are arranged on the inner side surface of the external thread end; a plurality of positioning grooves 221 with the same size are uniformly formed in the inner rod 220 from top to bottom; the positioning teeth 213 are in clutch contact with the positioning groove 221. The vertical cross section of the positioning teeth 213 and the vertical cross section of the positioning groove 221 are semi-circular with equal size. The distance between the positioning groove 221 and the center of the adjacent positioning groove 221 is not more than 0.5cm.

The nut 230 is tightened, and the top end of the outer cylinder 210 is slightly deformed, so that the positioning teeth 213 are engaged with the positioning grooves 221, thereby preventing the inner rod 220 from sliding up and down.

In order to slightly deform the top of the outer cylinder 210, the external thread end is provided with a conical external thread 211 or/and the nut 230 is provided with a conical internal thread. I.e., the external threads on the externally threaded end, or the internal threads on the nut 230, have at least one of a conical thread. Fig. 4 shows a case where the external thread 211 and the nut internal thread are both conical threads. The tapered thread design makes the external thread end of the outer cylinder 210 have a necking function, and the notch 212 makes the external thread end capable of necking, so that the inner rod 220 is fixed.
