[0002] Portable nursing infusion vehicle is a mobile infusion tool specially designed for the medical care field. It is usually composed of one or more wheelchairs, infusion stands, infusion pumps, pipes, valves, pressure gauges, blood bags, etc., and is used to provide infusion services in hospitals or outdoors. Portable nursing infusion vehicles are usually used in surgery, first aid, rehabilitation care, temporary medical facilities and other fields. It can provide fast, safe and reliable infusion services and improve the quality and efficiency of medical care services.

[0003] When the existing portable nursing infusion cart is in use, a driving force is usually applied to the universal wheels at the bottom to drive the portable nursing infusion cart to move. However, when the universal wheels arranged at the four corners of the bottom of the portable nursing infusion cart are fixed, medical staff are usually required to limit or release the limits respectively, and the fixing efficiency is relatively low. In addition, the hook on the top of the portable nursing infusion cart for hanging the infusion bottle is usually in a fixed state. When the user needs to move, the range of his movement is limited by the fixed distance of the hook, thereby reducing the user's range of movement and reducing his use experience.

[0004] Therefore, it is necessary to provide a new portable nursing infusion vehicle to solve the above-mentioned technical problems. Utility Model Content

[0007] The fixing assembly includes a double-headed screw and a sliding round rod respectively arranged on both sides of the inner wall of the supporting bracket, and the outer surfaces of both ends of the double-headed screw and the sliding round rod are respectively movably connected to two movable brackets, and the ends of the two movable brackets adjacent to the brake wheel are respectively oppositely provided with first limit brackets, and the outer side wall of the brake wheel is provided with a plurality of first deep grooves matching the size of the first limit bracket, and the ends of the two movable brackets adjacent to the universal wheel are respectively fixedly connected to the second limit bracket, and the second limit bracket is attached to the outer side wall of the rotating shaft set by the universal wheel.

[0008] Furthermore, movable holes matching the radial dimensions of the double-headed screw are respectively provided at two ends of one side of the support bracket adjacent to the double-headed screw.

[0009] Furthermore, one end of the double-ended screw rod extends out of the outer side wall of the support bracket, and the extended end of the double-ended screw rod is fixedly connected to an auxiliary rocker.

[0010] Furthermore, two first fixing blocks are respectively fixedly connected to two ends of the bottom of one side of the first limiting bracket adjacent to the brake wheel.

[0011] Furthermore, the cross-sectional size of the first fixing block matches the first deep groove formed on the brake wheel.

[0012] Furthermore, the cross section of one end of the first fixing block away from the first limiting bracket is arranged in a trapezoidal shape.

[0013] Furthermore, a second fixing block is fixedly connected to the bottom of one end of the second limiting bracket adjacent to the universal wheel, and the second fixing block is in contact with the outer side wall of the rotating shaft of the universal wheel.

[0014] Compared with the related art, the portable nursing infusion vehicle provided by the utility model has the following beneficial effects:

[0015] 1. The portable nursing infusion cart applies a force to the double-headed screw to make it rotate, thereby driving the movable bracket and the first limit bracket and the second limit bracket at the bottom thereof. When the double-headed screw rotates forward, the first limit bracket and the brake wheel are in a fit state, and the second limit bracket and the universal wheel are in a fit state, thereby limiting the movement of the infusion cart body and ensuring its stability during operation. When the double-headed screw is reversed, the first limit bracket can be separated from the first deep groove of the brake wheel, and the second limit bracket can be separated from the outer surface of the universal wheel, so that the infusion cart body can move freely and its flexibility is improved.

[0016] 2. The portable nursing infusion cart is provided with a sliding hook, which can hang the infusion bottle at its bend. When the user moves, the sliding hook can slide on the infusion cart body. When the infusion cart body is fixed, the user can move along the sliding distance of the sliding hook, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The fixing assembly includes a double-headed screw 6 and a sliding round rod 7 respectively arranged on both sides of the inner wall of the support bracket 2, and the outer surfaces of both ends of the double-headed screw 6 and the sliding round rod 7 are respectively movably connected to two movable brackets 8, and the ends of the two movable brackets 8 adjacent to the brake wheel 4 are respectively oppositely provided with first limit brackets 9, and the outer side wall of the brake wheel 4 is provided with a plurality of first deep grooves matching the size of the first limit bracket 9, and the ends of the two movable brackets 8 adjacent to the universal wheel 3 are respectively fixedly connected to the second limit bracket 11, and the second limit bracket 11 is attached to the outer side wall of the rotating shaft set on the universal wheel 3;

[0027] When the infusion vehicle body 1 moves, the two first limiting brackets 9 are in a state of not contacting the brake wheel 4, and the two second limiting brackets 11 are in a state of not contacting the universal wheel 3, so that the universal wheel 3 and the brake wheel 4 are in a movable state, so that the infusion vehicle body 1 can move freely;

[0028] When the infusion vehicle body 1 needs to be fixed, a rotational force is applied to the double-headed screw 6 to make it rotate and drive the two movable brackets 8 on its outer surface to move relative to each other. The other side of the movable bracket 8 will slide on the outer surface of the sliding round rod 7, so as to maintain stability during movement. During the movement, the movable bracket 8 will drive the two first limiting brackets 9 and the two second limiting brackets 11 to move synchronously.

[0032] The working principle provided by the utility model is as follows: during the specific implementation of the utility model, when the infusion vehicle body 1 needs to be fixed, a rotational force is applied to the double-headed screw 6 to make it rotate and drive the two movable brackets 8 on its outer surface to move relative to each other, and the other side of the movable bracket 8 will slide on the outer surface of the sliding round rod 7, so as to maintain stability during movement. During the movement, the movable bracket 8 will drive the two first limiting brackets 9 and the two second limiting brackets 11 to move synchronously. During the movement, the first limiting bracket 9 will contact the first deep groove of the brake wheel 4 and fit to its inner wall, so as to limit the center angle of the circle on both sides thereof. During the movement, the second limiting bracket 11 will contact the rotating shaft of the universal wheel 3 and squeeze it, so as to limit the rotation angle of the top of the universal wheel 3, so as to fix the infusion vehicle body 1;

[0033] When the infusion vehicle body 1 needs to be moved, a force is applied to the double-headed screw 6 to make it rotate in the opposite direction, so that the first limiting bracket 9 and the second limiting bracket 11 are disengaged, thereby allowing the infusion vehicle body 1 to move freely.
