[0006] Furthermore, the shell is provided with an open side and a closed side, and a compression spring connecting the two is provided at one end of the control rod close to the closed side, the clamping column is located at this end and faces the reel, and a press cover is provided at one end of the control rod close to the open side, and the press cover keeps synchronous movement with the clamping column.

[0007] Furthermore, one end of the movable hook is hinged to the shell, and the other end is provided with a screw nut which can be screwed into a screw hole provided on the shell.

[0008] Furthermore, the hanging device is located above the transparent bag body, and the distance between the bag body and the hanging device is 0 cm to 50 cm.

[0009] Furthermore, the control rod is cylindrical in the inner section of the reel, and is provided with a square column in the outer section of the reel. The square column is located in a square hole provided in the shell and can translate but cannot rotate.

[0010] Furthermore, the lower end of the hanging rope is connected to the bag body via a connecting piece.

[0011] Furthermore, a groove concave upwards is provided in the middle of the movable hook.

[0012] Furthermore, the reel is connected to the housing via a bearing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model has a firm suspension and strong adaptability. By pressing the cover, the clamping column and the clamping slot provided on the reel can be separated, and the reel can rotate freely. As the length of the suspension rope extending out of the shell changes, the distance between the bag body and the suspension device also changes, so the distance between the bag body and the suspension device connected thereto can be adjusted from 0cm to 50cm according to actual use requirements, and the utility model has strong adaptability. In addition, the tightness of the connection between the movable hook and the fixed object can be adjusted, and the tightness of the connection can be increased to prevent the PVC soft bag from slipping and other accidents, thereby improving the safety of infusion.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 to Figure 4As shown, a PVC soft bag that is easy to hang includes a bag body 1 and a hanging device 2 connected thereto. The bag body 1 is made of transparent medical-grade material and has a volume of 50 to 600 ml. The hanging device 2 includes a shell, on which is provided a movable hook 2a for fixing to an object such as an infusion stand, and inside which is provided a rotatable reel 2b, which is connected to the shell through a bearing 2k. A hanging rope 2c whose end is connected to the bag body 1 is wound around the outside of the reel 2b, and a control rod 2d is passed through the inside. The control rod 2d is non-rotatable and connected to a clamping column. When the clamping column extends into a clamping groove provided on the reel 2b, the reel 2b does not rotate. The hanging device 2 is located above the bag body 1, and the lower end of the hanging rope 2c is connected to the bag body 1 through a connecting piece 2j. As the length of the hanging rope 2c extending out of the shell changes, the distance between the bag body 1 and the hanging device 2 also changes, and the value is 0 cm to 50 cm.

[0022] Specifically, in order to realize the function of the control rod 2d, the shell is provided with an open side and a closed side, and a compression spring 2e connecting the two is provided at one end of the control rod 2d close to the closed side, and a clamping column is located at this end and faces the reel 2b, and a press cover 2f is provided at one end of the control rod 2d close to the open side, and the press cover 2f keeps synchronous movement with the clamping column. When the press cover 2f is pressed into the shell body by overcoming the force of the compression spring 2e, the clamping column is separated from the clamping groove provided on the reel 2b, and the reel 2b can rotate freely, thereby realizing that the distance between the bag body 1 and the suspension device 2 connected thereto is adjusted according to actual use requirements, and the adaptability is strong and can be adapted to infusion stands of different heights; in addition, in order to limit the rotation of the control rod 2d, the control rod 2d located in the inner section of the reel 2b is a cylinder, and a square column 2i is provided in the outer section of the reel 2b, and the square column 2i is located in the square hole provided in the shell body and can translate but cannot rotate.

[0023] In order to enhance the connection convenience and stability of the movable hook 2a, one end of the movable hook 2a is hinged to the shell, and the other end is provided with a screw nut 2g, which can be screwed into the screw hole 2h opened on the shell. The middle part of the movable hook 2a is provided with an upward concave groove to facilitate fixation with a columnar object. By screwing the nut 2g, the tightness of the connection between the movable hook 2a and the fixed object can be adjusted. Increasing the connection tightness can prevent the PVC soft bag from slipping and other accidents, thereby improving the safety of infusion.

[0024] The utility model discloses a PVC soft bag which is easy to hang and has the functions of connection locking and length adjustment. When the bag is fixed to an infusion stand, the tightness of the connection between the movable hook 2a and the fixed object can be adjusted by screwing the nut 2g, thereby improving the tightness of the connection so that the PVC soft bag is not prone to accidents such as slipping, thereby improving the safety of infusion. When it is necessary to adapt to infusion stands of different heights, the cover 2f can be pressed to separate the card column from the card slot provided on the reel 2b, and the reel 2b can rotate freely. As the length of the hanging rope 2c extending out of the shell changes, the distance between the bag body 1 and the hanging device 2 also changes, thereby achieving the adjustment of the distance between the bag body 1 and the hanging device 2 connected thereto according to actual use requirements. The bag has strong adaptability and is suitable for hanging connection points of various heights.

[0025] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, relevant changes, modifications or additions should all fall within the protection scope of the utility model.
