DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figure 1:

A good limb positioning auxiliary device comprises an auxiliary shell 1 and a plurality of support columns 2 vertically movable inside the auxiliary shell 1, wherein the support columns 2 can extend out of the upper surface of the auxiliary shell 1;

The height of the plurality of support columns 2 can be adjusted independently, and can actively adapt according to the shape and posture of the patient's limbs. In other words, the plurality of support columns 2 can provide targeted support for the shape and posture of any limb, thereby improving the patient's comfort level.

As shown in Figure 9, taking arm 7 as an example, when the patient is in the healthy side lying position, for example, when the patient faces the right side, the left arm 7 will be suspended in the air and cannot directly contact the bed board 9. The traditional way is to support the suspended arm 7 through a support pad 8. The support pad 8 is a soft pad 6 that can support the patient's limbs. A pillow is commonly used. As shown in the figure, the higher part of the support pad 8 is subjected to less force, while the flattened part of the support pad 8 is subjected to greater force, resulting in obvious local compression of the patient's limbs. For the same reason, the support for the legs will also have the problem of obvious local compression due to uneven force.

More specifically:

As shown in Figure 1 to Figure 8:

In combination with the above content: the good limb positioning auxiliary device also includes the auxiliary shell 1 having one end fixedly connected to a hose 3, one end of the hose 3 being fixedly connected to a hand-held pressurized ball 31, the other end of the hose 3 being fixedly connected to a distribution main pipe 32, one end of the distribution main pipe 32 being fixedly connected to the bottom of a plurality of soft branch pipes 33, the inner side of the auxiliary shell 1 at the bottom spatial position for the support column 2 to move is fixedly connected to the top of the soft branch pipe 33, the outer surface of the support column 2 is mechanically sealed with the inner wall surface of one end of the auxiliary shell 1 by a sliding type, and the plurality of support columns 2 can move independently in the vertical direction.

In this embodiment: the external gas is input into the inner side of the hose 3 by holding the pressurizing ball 31, the air inside the hose 3 will enter the inner side of the distribution main pipe 32, the air inside the distribution main pipe 32 will enter the inner side of the soft branch pipe 33, the air inside the soft branch pipe 33 will enter the inner side of the space of the auxiliary shell 1 for the support column 2 to move, and under the influence of the gas pressure, the support column 2 will move upward, and when the support column 2 needs to move downward, the gas can be released by holding the pressurizing ball 31.

Going further;

In an optional embodiment, two parallel fixed plates 4 are fixedly connected to the inner side of the bottom end of the auxiliary shell 1, and the two fixed plates 4 are each provided with a first through hole 41, and the first through hole 41 can allow the soft branch pipe 33 to pass through. The left and right side edges of the two fixed plates 4 are fixedly connected with connecting brackets 42, and a movable plate 43 is arranged between the two fixed plates 4. The movable plate 43 is provided with a second through hole 44 corresponding to the position of the first through hole 41, and the second through hole 44 can allow the soft branch pipe 33 to pass through.

In an optional embodiment, the left and right ends of the movable plate 43 are fixedly connected with a sliding bar 45, one end of the connecting bracket 42 is provided with a sliding groove that can match the sliding bar 45, and one end of the movable plate 43 is provided with a threaded hole 46 on the inner side, and a threaded rod 47 is threadedly connected at the position of the threaded hole 46 of the movable plate 43, and a smooth surface part 471 is provided at one end of the threaded rod 47, and the smooth surface part 471 of the threaded rod 47 is rotatably connected to the inner side of one end of the auxiliary shell 1, and one end of the threaded rod 47 extending to the external space of the auxiliary shell 1 is fixedly connected with a knob 48.

In this embodiment: under the influence of gas pressure, the support column 2 will move upward. When the support column 2 touches the patient's limbs while moving upward, the support column 2 will stop moving. Other support columns 2 that have not yet contacted the patient's limbs will continue to move under the influence of gas pressure until the support column 2 contacts the patient's limbs, or the support column 2 stops after reaching the maximum stroke. The limit ring 21 fixedly installed on the outside of the support column 2 slides in the limit groove 22 opened on the inner side of one end of the auxiliary shell 1. The moving stroke of the support column 2 is controlled by the length of the limit groove 22. When the support column 2 meets the shape of the supported patient's limb, the position of each support column 2 at this time needs to be fixed. By turning the knob 48, the knob 48 drives the threaded rod 47 to rotate. The rotation of the threaded rod 47 will drive the movable plate 43 to move. The movement of the movable plate 43 will cause the second through hole 44 to be staggered with the first through hole 41 on the fixed plate 4, so as to clamp the soft branch tube 33, so that the soft branch tube 33 is disconnected and no longer ventilated, and finally the position where each support column 2 stays is fixed.

In an optional embodiment, the left and right ends of the auxiliary shell 1 are fixedly connected with the second magic tape 52, the outer surface of the auxiliary shell 1 is covered with a non-elastic cloth 5, and the inner sides of the left and right ends of the non-elastic cloth 5 are fixedly connected with the first magic tape 51, the first magic tape 51 and the second magic tape 52 can be adhered and fixed to each other, and there are multiple non-elastic cloths 5.

In this embodiment: when the large-area support column 2 does not need to be moved, that is, when the large-area support column 2 does not contact the patient's limbs, the part of the support column 2 is covered by the non-elastic cloth 5, so that the part of the support column 2 cannot move upward, and the position covered by the non-elastic cloth 5 can be replaced by the cooperation of the first magic adhesive 51 and the second magic adhesive 52.

As shown in FIG. 8 , a soft pad 6 may be placed between the patient's limb and the device as needed to achieve a more uniform force distribution.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
