[0018] 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 of 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.

[0019] See also Figure 1-3The utility model provides a technical solution: a mechanism for assisting the cover of an enteral nutrition infusion device, comprising a bottom plate 1, side plates 2 are symmetrically fixed on both sides of the bottom plate 1, a top plate 3 is fixed on the side plates 2, a swivel seat 4 is fixed on the top plate 3, a swivel rod 5 is hinged on the swivel seat 4, a handle 6 is fixedly connected to the end of the swivel rod 5 away from the swivel seat 4, an upper ear plate 7 is fixedly provided at the bottom of the swivel rod 5, a connecting plate 8 is hinged on the upper ear plate 7, a lower ear plate 9 is hinged on the side of the connecting plate 8 away from the upper ear plate 7, and a pressing cylinder 10 for assisting the cover is fixedly connected to the side of the lower ear plate 9 away from the upper ear plate 7.

[0020] Specifically, a groove 11 is formed on the side wall of the pressing cylinder 10 for the pipe on the buckle cover to pass through, and a pressing plate 12 is fixedly provided at the bottom of the pressing cylinder 10. A rubber pad is provided at the bottom of the pressing plate 12 to increase the pressing area of ​​the cover when the pressing cylinder 10 presses down, so that the cover can be more stably covered on the infusion set, and the rubber pad prevents the cover from being damaged by pressure when the pressing cylinder 10 is pressed down.

[0021] Specifically, a rubber pad is provided on the inner wall of the side where the two side panels 2 are close to each other, and the two side panels 2 are in contact with the side wall of the infusion set. When the infusion set is covered, the infusion set is placed between the two side panels 2, and the side panels 2 are in contact with the side wall of the infusion set. The rubber pad can increase the friction with the infusion set and prevent the side wall of the infusion set from being worn.

[0022] Specifically, a rubber ring is provided on the handle 6 to improve the hand feel. The distance from the upper ear plate 7 to the hinge of the swivel seat 4 is much smaller than the distance from the upper ear plate 7 to the end of the handle 6, so that the force arm is greater than the resistance arm, thereby reducing the force exerted when buckling the cover and making the operation labor-saving.

[0023] Specifically, an extension rod 13 is fixedly provided at one end of the rotating rod 5 away from the grip 6, an upper ring 15 is fixedly provided on the extension rod 13, a lower ring 14 is fixedly provided on the top plate 3, and a tension spring 16 is hooked between the lower ring 14 and the upper ring 15. Through the setting of the tension spring 16, the rotating rod 5 can maintain a balanced state when not in use, which is convenient for use when the cover is buckled. After the cover buckling operation is completed, the rotating rod 5 moves up under the elastic force of the tension spring 16 and drives the pressing cylinder 10 to move up and away from the infusion set, thereby improving the convenience of operation.

[0024] Specifically, a suction cup 17 is fixedly provided on the bottom plate 1, and four suction cups 17 are evenly arranged along the bottom plate 1, which can improve the stability of the device placement and prevent the device from moving on the desktop.

[0025] A specific application example of this embodiment is:

[0026] When the device is in use, the device is placed on a flat surface, the infusion set is placed on the bottom plate 1 and between the two side plates 2, the cover is pre-covered at the cover-fastening position of the infusion set, the grip 6 is pressed downward to drive the pressing cylinder 10 to press down the cover, and the cover can be easily fastened on the infusion set by utilizing the lever principle. During the pressing process of the grip 6, the tension spring 16 is stretched. After the cover is fastened, the rotating rod 5 is reset under the elastic force of the tension spring 16 and drives the pressing cylinder 10 to reset, and the infusion set with the cover fastened can be taken out, which is convenient and labor-saving to operate.
