Example 1

A lower limb position adjustment device as shown in figure 1, the adjustment device may hold and support a patient's lower limb during use by the patient. The adjusting device at least comprises a base 1, a first supporting rod 2, a spherical connecting piece 4 and a leg accommodating piece 3, wherein the near-ground end of the first supporting rod 2 is connected to the base 1 so that the first supporting rod 2 is positioned at a specific position of the base 1. The distal end of the first support rod 2 is connected to the ball-shaped connection member 4. The distal end of the first support bar 2 is arranged as a recess 21 for receiving the ball joint 4. The first support rod 2 has an adjustable height, the first support rod 2 includes at least one adjusting portion 22, and a fitting portion between the adjusting portion 22 and the first support rod 2 is provided with a positioning pin 221 for controlling the height of the lower limb position adjusting device and an adjusting hole 222 for receiving the positioning pin, as shown in fig. 6. The positioning pin 221 is pulled out from the adjusting hole 222, the first supporting rod 2 is pulled out from the inside of the adjusting part 22, when the height of the lower limb needed by the patient is adjusted, the positioning pin 221 is inserted into the adjusting hole 222 at the corresponding position, and the lower limb position adjusting device is kept at the height; similarly, when the height of the adjustment device needs to be reduced, the positioning pin 221 is pulled out from the adjustment hole 222, the first support rod 2 is retracted into the adjustment portion 22, and then the positioning pin 221 is inserted into the adjustment hole 222 at the corresponding position, so that the lower limb position adjustment device can be maintained at the height. Preferably, the adjusting part 22 may be a tubular rod body wrapping the first support rod 2. Preferably, the first support rod 2 is not completely wrapped inside the adjustment portion 22, so that the first support rod 2 located inside the adjustment portion 22 is partially exposed.

The leg accommodating member 3 is provided with a concave surface 31 formed by splicing two tangential surfaces in the axial direction, which can restrict the lower limb from slipping off the support portion, as shown in fig. 1-2. The lower part of the concave surface 31 of the leg accommodating member 3 is provided with a hollow passage 32. The gap formed by the concave surface 31 and the hollow passage 32 is smaller than the width of the lower limb so as to avoid the lower limb placed on the concave surface of the leg container 3 from collapsing. The hollow channel 32 allows ventilation of the lower limb portion placed on the leg housing 3.

As shown in fig. 3, the area on the ball-shaped connector is described, and when the ball-shaped connector 4 is in the first state, the healthcare worker places the lower limb of the patient lying on the leg receiving member and adjusts the leg receiving member to the proper position, and the contact area of the ball-shaped connector 4 with the first support bar 2 is the first area 42. The second area 43 is provided as an area which is not in contact with the first support rod 2 when the ball joint 4 moves relative to the first support rod 2.

The first region 42 of the ball joint 4 is connected to the distal end of the first support rod 2. A second support bar 41 extending from the ball-shaped connection member 4 is connected to the leg receiving member 3 so that the leg receiving member 3 can rotate with respect to the first support bar 2. The ball-shaped connection 4 may allow the leg receptacle 3 to rotate in at least one direction. When the patient changes from lying to lying on his side, the third region 44 of the ball-shaped link 4 comes into contact with the distal end of the first support bar 2, the lower limb placed in the leg-receiving member 3 can rotate in the same direction as the ball-shaped link 4, and since the leg-receiving member 3 is provided with the concave surface 31 restricting the slippage of the lower limb, the lower limb of the patient can be held in the leg-receiving member 3 while lying on his side without slipping out. The recess 21 is provided with a protrusion 211 resisting rotation, as shown in fig. 4. According to a preferred embodiment, the protrusion 211 is a separate sphere adapted to the recess 431. The second region 43 of the ball-shaped connector 4 is provided with grooves 431 that can be engaged with the protrusions 211 of the recess 21, and the second region 43 is provided with a plurality of grooves 431. Preferably, the grooves 431 disposed on the second area 43 are arranged circumferentially. The interaction of the protrusion 211 and the groove 431 may limit the range of movement of the leg receiver 3. When the patient lies on the back, the lower limb placed on the leg accommodating part 3 can move towards the upper limb end, and when the leg accommodating part 3 moves towards the direction far away from or near to the upper limb end to reach the first position, the medical staff places the protrusion 211 into the groove 431, and the leg accommodating part 3 cannot move along the axial direction of the human body but can turn right and left due to the fact that the groove 431 on the spherical connecting part 4 is clamped with the protrusion 211. Moreover, since the grooves 431 disposed on the second region 43 are circumferentially arranged, the protrusions 211 may engage with the grooves 431 at different positions, so that the lower limb of the patient may move toward the upper limb by different distances, and the patient may select the engaging position according to the comfort level. After the protrusion 221 is engaged with the groove 431, the lower limb of the patient can be kept at a proper height and angle, that is, the patient does not need to use the lower limb force to keep the leg accommodating member 3 at a required position, so that the force of the patient can be saved.

The ball joint 4 is detachably connected to the distal end of the first support bar 2. Preferably, the ball-shaped connection 4 may be comprised by the first support bar 2 as part of the first support bar 2. Preferably, the ball-shaped connection 4 may be comprised by the leg receptacle 3 as part of the leg receptacle 3. The spherical connecting piece is detachably connected with the leg accommodating piece, and the spherical connecting piece 4 is detachably connected to the distal end of the first support rod 2. The detachable connection facilitates cleaning or sterilization of the ball-shaped connector and the leg receptacle. For example, the ball joint 4 and the leg receptacle 3 may be removed from the adjustment device, and the removed components sterilized using an autoclave or other similarly functioning machine. Preferably, the ball-shaped connector 4 and the leg receiving member 3 are provided as a unitary structure, and the ball-shaped connector 4 is detachably connected to the distal end of the first support rod 2, so that the ball-shaped connector 4 and the leg receiving member 3 can be integrally detached for cleaning or sterilization. Preferably, the leg receiving member 3 may be disposable, while the base 1, the first support bar 2 and the ball joint 4 are reusable.

Example 2

The repeated contents in embodiment 1 will not be repeated in this embodiment.

The ball joint 4 comprises a ball 45 and a ball-receiving adapter 46, as shown in fig. 5. The adapter 46 is provided with a recess that receives at least a portion of the ball, the recess being sized and shaped to allow the ball to be friction or snap fit within the recess. The ball 45 is movable relative to the adapter 46. Preferably, the adapter 46 may include an opening 462 and a fastener 461, the ball 45 being placed in a recess of the adapter 46, the fastener 461 being rotatable to tighten both sides of the opening 462 toward each other. Preferably, the fastener 461 may be a nut. The adapter 46 is clamped to the ball so that the ball and the adapter interfere with each other. At the same time, the degree of clamping between the adapter 46 and the ball 45 can be adjusted as the case may be, so as to vary the resistance to movement of the ball joint 4. Preferably, the adapter 46 is detachably connected to the ball 45.

The resistance to movement of the ball joint 4 is adjustable. The movement resistance of the spherical connecting piece 4 can be configured to be small, so that the patient can easily and conveniently adjust the angle of the lower limb; the movement resistance of the spherical connecting piece 4 can be configured to be larger, for example, the lower limbs of some special patients cannot move to a larger extent, and the larger movement resistance can ensure that the lower limbs of the patients do not move frequently, so that the accident of secondary injury is prevented.
