[0042] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0043] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] The present disclosure provides an infusion chair, comprising a base, a backrest, a first locking mechanism, an infusion bracket, a second locking mechanism, a leg support and a third locking mechanism, wherein the backrest is rotatably arranged on the base; the first locking mechanism is configured to lock the backrest and the base after the backrest is rotated by a preset angle relative to the base; the infusion bracket is rotatably arranged on the backrest; the second locking mechanism is configured to lock the infusion bracket and the backrest after the infusion bracket is rotated by a preset angle relative to the backrest; the leg support is rotatably arranged on the base; the third locking mechanism is configured to lock the leg support and the base after the leg support is rotated by a preset angle relative to the base.

[0045] In this way, when the patient is receiving an infusion, the backrest and leg support can be rotated to a preset angle according to their own needs to adapt to the lying position of the human body, and the backrest and leg support are fixed by the first locking mechanism and the third locking mechanism, thereby ensuring the safety of the patient lying on the infusion chair. The infusion bracket can be rotated to a certain angle relative to the backrest to maintain a vertical position, and the position of the infusion bracket is fixed by the second locking mechanism for hanging the infusion bottle. Compared with sitting, the patient can reduce fatigue when receiving an infusion in a lying position on the infusion chair.

[0046] For ease of understanding, refer to Figures 1 to 5 , the specific structure and working principle of the infusion chair disclosed in the present invention are explained in detail in combination with an embodiment.

[0047] like Figure 1As shown, the present disclosure provides an infusion chair, which includes a base 1, a backrest 2, a first locking mechanism 3, an infusion support 4, a second locking mechanism 5, a leg support 6 and a third locking mechanism 7.

[0048] Specifically, in one embodiment of the present disclosure, the backrest 2 also includes a U-shaped bracket 21 and a back support 22. The two cantilever ends of the U-shaped bracket 21 are connected to the base 1 through a rotating shaft and can rotate relative to the base 1. The back support 22 is connected to the inner side of the U-shaped bracket 21 at multiple locations.

[0049] Specifically, the U-shaped bracket 21 can be made of aluminum alloy or stainless steel, which can reduce weight and ensure the safety of the bracket. The U-shaped bracket 21 rotates relative to the base 1 through a rotating shaft and can be rotated to a preset angle that matches the lying position of the human body. The inner side of the U-shaped bracket 21 is connected to the back support 22 at multiple locations. A plurality of hooks can be provided on the back support 22, which are connected to the cantilever rod of the U-shaped bracket 21, or directly connected by bundling. The back support 22 can be made of flexible materials such as nylon, leather, sponge, etc. When the patient lies on the infusion chair, the back support 22 can adaptably fit the human back completely, provide support force to the human back, and enable the patient to reduce fatigue and maintain comfort during a longer infusion time.

[0050] like Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, the first locking mechanism 3 also includes a slot 31, a connecting plate 32 and a block 321. Specifically, the slot 31 is arranged at the cantilever end of the U-shaped bracket 21, the base bracket 11 has a protruding end through a bolt connection, the connecting plate 32 has a groove and can be rotatably arranged on the base 1 around the protruding end, and the block 321 is arranged at one end of the connecting plate 32.

[0051] Specifically, when the backrest 2 is rotated to a preset angle, the slot 31 approaches the connecting plate 32 and the block 321, and the connecting plate 32 is rotated and pushed into the slot 31 by an external force, thereby completing the locking of the backrest 2 and the base 1. Under the gravity of the backrest 2, the backrest 2 generates a torque relative to the base 1, and the block 321 contacts the slot 31 to generate a torque in the opposite direction, and the torques of the two offset each other, so that the backrest 2 is fixed in a lying position. When the patient's infusion is finished, the connecting plate 32 is rotated under the action of an external force and pushed out of the slot 31, and the backrest 2 can be rotated relative to the base 1 through the rotating shaft and restored to a neutral position, saving space.

[0052] like Figure 4 As shown, in one embodiment of the present disclosure, the second locking mechanism 5 further includes a screw 51, which is threadedly connected to the backrest 2, and the infusion bracket 4 is arranged on the screw 51 in a threaded connection or an interference fit connection.

[0053] Specifically, the screw rod 51 is threadedly connected to the backrest 2, and the end of the screw rod extends out. The infusion bracket 4 is threadedly connected to a sleeve extending from the end of the rod, and the sleeve is connected to the end of the screw rod 51 through an interference fit. When the backrest 2 is rotated to a preset angle, the infusion bracket 4 is rotated to a neutral position by an external force to facilitate hanging of an infusion bottle.

[0054] A circular baffle is also provided at the end of the screw 51 to prevent the sleeve from slipping out. The circular baffle can be fixed to the end of the screw 51 by bonding or welding. Since the infusion bottle is light in weight, and the infusion bracket 4 will be adaptively adjusted to a neutral position by external force as the backrest 2 rotates, there is no torque relative to the screw 51, or the infusion bracket 4 has a small angle with the vertical position. At this time, the infusion bracket 4 generates a small torque relative to the screw 51, and the pre-tightening force of the interference fit between the screw 51 and the sleeve can completely offset the small torque of the infusion bracket 4. In addition, the sleeve and the end of the screw can also be threaded to improve stability.

[0055] In one embodiment of the present disclosure, the leg support 6 also includes a leg bracket 61 and a leg support member 62, the leg bracket 61 includes two rods hinged to each other, and the two ends of one side of the two rods are slidably arranged on the base 1 through sleeves, and the leg support member 62 is connected to the other ends of the two rods of the leg bracket 61.

[0056] Specifically, the leg support 61 has two rods, the middle section of the rod has a through hole and a rotating shaft, the two rods are hinged by the rotating shaft, and rotate relative to the hinge point by a preset angle under the action of an external force, and the preset angle is that one end of the two rods is far away from the human leg or the leg support 62 is fully unfolded. The leg support 61 can be made of aluminum alloy or stainless steel, which can reduce the weight and ensure the safety of the support. The leg support 62 can be made of flexible materials such as nylon, leather, sponge, etc., and is provided with multiple hooks, which are fixed to the inner side of the leg support 61 at multiple points.

[0057] like Figure 5 As shown, in one embodiment of the present disclosure, the third locking mechanism 7 also includes a fixing member 71 and a hinge 72.

[0058] Specifically, the shape of the fixing member 71 is not limited, and can be round or square, with a slot on the top to accommodate the rods of the base bracket 11 and the leg bracket 61. The part of the slot that accommodates the rod is a circular slot, so that the rod is placed vertically in the fixing member 71, and also includes a trapezoidal slot to accommodate the rotation of the rod.

[0059] The hinge 72 is arranged in the circular groove of the fixing member 71, and is connected to one end of the base bracket 11 and the leg bracket 61. Under the action of external force, the leg bracket 61 can rotate on the hinge 72, and the maximum rotation angle is to rotate to the step surface of the trapezoidal groove. At this time, the leg support member 62 is fully unfolded, and can accommodate the human calf to be placed on the leg support member 62. One side of the rod of the base bracket 11 and the leg bracket 61 is in contact with the step surface. The torque generated by the support force of the step surface on the rod is offset by the torque generated by the rod relative to the hinge 72 under its own weight. The rod is fixed relative to the trapezoidal groove, and the leg bracket 61 and the base bracket 11 are locked.

[0060] In one embodiment of the present disclosure, the base 1 also includes a base bracket 11 and a base support 12. The base bracket 11 and the leg bracket 61 are both foldable brackets, and the base support 12, the back support 22 and the leg support 62 are integrally formed flexible supports.
