Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides an anti-drag device for transfusion system, which comprises a buckle 1 for hanging on a transfusion stand and a fixing component 2 for clamping a transfusion needle, wherein the buckle 1 is connected with the fixing component 2 through an adjusting belt 3.

In the embodiment, the retaining ring 1 is in a common annular structure and is used for being hung on a hook of an infusion support, and when the infusion support is actually used, the retaining ring can be made into a clamp shape and directly clamped on the infusion support, or made into an annular frame and directly clamped on a round hole of an infusion bag, and the specific structure of the retaining ring 1 is not limited; the upper end of the adjusting belt 3 is fixed on the infusion support through the retaining ring 1, and the lower end of the adjusting belt 3 is fixed at the bottom of the clamping piece of the infusion joint through the fixing component 2, so that the infusion joint is prevented from being separated from the infusion bag or the infusion bottle due to the fact that the infusion tube is pulled by a hand arm.

Wherein, fixed subassembly 2 includes the equipment ring body 201 be equipped with a plurality of plastic housing 202 on the equipment ring body 201 plastics housing 202 internal rotation is installed plastics ratchet 203, just the claw body 204 that plastics ratchet 203 bottom was installed, just the claw body 204 extends to the external world and rotates along with plastics ratchet 203 from plastics housing 202, plastics housing 202 has backstop inserted sheet 206 through arc shell fragment 205 slidable mounting, just the one end nestification of backstop inserted sheet 206 is in the intertooth space of plastics ratchet 203.

The assembling ring body 201 is an annular structure far larger than the bottom end of an infusion bottle or an infusion bag, before the infusion connector is connected, the assembling ring body 201 is sleeved at the bottom end of the infusion bottle, the infusion connector is inserted into the infusion bottle or the infusion bag, at the moment, the claw body 204 moves towards the circle center of the assembling ring body 201, so that the inner end of the claw body 204 clamps the bottom of a clamping piece of the infusion connector, and the infusion connector is prevented from sliding downwards.

Taking the left pawl 204 as an example, that is, the pawl 204 rotates counterclockwise to approach the infusion connector, only the pawl 204 needs to be rotated counterclockwise manually, the pawl 204 is transferred to the plastic ratchet 203 after being stressed, so that the plastic ratchet 203 has a tendency of rotating counterclockwise, and the anti-back insert 206 nested at the lower end of the plastic ratchet 203 is movably mounted on the plastic housing 202 through the arc-shaped elastic sheet 205, and can slide linearly along the initial position, through the special physical shape of the plastic ratchet 203, the anti-back insert 206 cannot block the rotation of the plastic ratchet 203 when the plastic ratchet 203 rotates counterclockwise, and when the plastic ratchet 203 backs (i.e. rotates clockwise), the anti-back insert 206 forms a great resistance to block the clockwise rotation of the plastic ratchet 203, so as to adjust and lock the position of the plastic ratchet 206.

Wherein the end of the claw body 204 is U-shaped.

The infusion joint is clamped and fixed from different sides by the claw bodies 204 through the U-shaped end parts of the claw bodies 204 to be attached to the surface of the infusion joint; in particular, the bottom heights of the respective claws 204 are set to be slightly different in order to prevent the claws 204 from interfering with each other and affecting the clamping effect.

As shown in fig. 1, fig. 2 and fig. 4, the adjusting belt 3 includes a belt body 301 fixedly connected to the buckle 1 and a slide hole 302 formed in the assembly ring body 201, the belt body 301 is nested in the slide hole 302, a clamping groove 306 is formed in the belt body 301, a movable cavity 303 is formed in one side of the slide hole 302, an elastic pressing body 304 for nesting the clamping groove 306 is installed in the movable cavity 303, and an operating rod 305 hinged to the elastic pressing body 304 is arranged in the movable cavity 303.

The height of the fixing component 2 can be adjusted by adjusting the structure of the belt 3 so as to adapt to structures of different types of infusion joints, infusion bags, infusion bottles and the like.

The elastic pressing body 304 can be made of a slightly elastic plastic material, and the elastic pressing body 304 is arranged at the top end of the movable cavity 303, so that the right end of the elastic pressing body 304 is nested on the clamping groove 306 of the belt body 301, and the belt body 301 is fixed; when the belt body 301 needs to slide in the sliding hole 302 to adjust the height of the fixing assembly 2, the operating rod 305 is pulled to the right side manually, and the elastic pressing body 304 is pulled by the operating rod 305 to move to the left side, so that the elastic pressing body 304 does not limit the position-locking groove 306.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
