Example one

As shown in figure 1, the safety transfusion needle comprises a puncture-proof sleeve 1, an upper pipe clamp 2, a lower pipe clamp 3, a liquid pipe 4 and a needle handle 5, wherein one end of the needle handle 5 is connected with the liquid pipe 4, the other end of the needle handle is fixedly connected with a needle head, a needle wing 6 is arranged on the handle side of the needle handle 5, the puncture-proof sleeve 1 is a hollow round pipe with an opening seam 7 on one side, the upper pipe clamp 2 and the lower pipe clamp 3 are arranged on one side of the puncture-proof sleeve 1, which is back to the opening seam 7, and form a clamp structure, one end of the puncture-proof sleeve 1 is sleeved on one end of the needle handle 5, which is fixedly connected with the needle head, and the needle head is completely positioned in an inner cavity of the puncture-proof sleeve 1.

The tube body of the puncture-preventing sleeve 1 is connected with the liquid tube 4 or the needle handle 5 through the connecting rope 8.

The clip structure of the puncture-preventing sleeve 1 is connected with the liquid tube 4 or the needle handle 5 through the connecting rope 8.

The puncture-preventing sleeve 1 is made of plastic materials.

As shown in fig. 1-6, which are schematic views of the use process of the present invention, during the infusion process, the puncture-proof cannula 1 will not be lost due to the existence of the connecting rope 8, the puncture-proof cannula 1 can be recycled after the infusion is completed, the use method is the same as that of a common intravenous infusion needle, and the puncture-proof cannula 1 does not need to be recycled to a rear fluid tube during the use, thereby reducing the contact and the infection risk. Meanwhile, the utility model adopts the clamp structure to press open the puncture-proof sleeve 1 with the opening seam so that the puncture-proof sleeve can be directly sleeved on the needle handle 5, thereby well solving the problem of colloid viscous resistance when the puncture-proof sleeve 1 slides to cover the needle after the transfusion is finished, and the residual transfusion paste can increase the friction force between the needle handle 5 and the puncture-proof sleeve 1 instead, so that the jacket is more stable, the puncture risk is further reduced, meanwhile, the whole use and operation are simple and safe, and the connection rope of the puncture-proof sleeve 1 can not influence the fixation of the needle.

Example two

As shown in fig. 7-9, the basic structure of this embodiment is the same as that of the first embodiment, except that: the two sides of the needle wing 6 of the needle handle 5 are both provided with annular clamping grooves, the end part of the puncture-proof sleeve 1 is provided with a semicircular buckle corresponding to the annular clamping groove, as shown in fig. 7, the state schematic diagram of the puncture-proof sleeve 1 and the needle handle 5 is shown, when the infusion apparatus is not used, the combination state of the puncture-proof sleeve 1 and the needle handle 5 is shown in fig. 8, when the infusion apparatus is recovered, the combination state of the puncture-proof sleeve 1 and the needle handle 5 is shown in fig. 9, the semicircular buckle of the puncture-proof sleeve 1 is clamped in the annular clamping groove corresponding to the needle handle 5, the needle wing 6 of the needle handle 5 is positioned in the open groove of the puncture-proof sleeve 1 to circumferentially position the puncture-proof sleeve 1, and the annular clamping groove and the semicircular buckle realize axial positioning, so that the sleeving stability of the puncture-proof sleeve 1 is ensured, and the needle head is effectively protected.

The rubber plug strip 9 is filled in the tube cavity of one end, far away from the needle handle 5, of the puncture-proof sleeve 1, as shown in fig. 8-9, the rubber plug strip 9 inside the puncture-proof sleeve 1 is separated from the needle head when the infusion apparatus is not used, infection to the needle head and the like can not be caused, even the effect of isolation protection can be realized, after infusion is finished and the puncture-proof sleeve 1 needs to be recycled, the whole puncture-proof sleeve 1 is sleeved on the needle handle 5 through the clamp structure, at the moment, the needle head is positioned in the tube cavity of the puncture-proof sleeve 1, the puncture-proof sleeve 1 is moved slightly again, the end part of the needle head can be punctured into the rubber plug strip 9, the liquid medicine in the liquid tube 4 is prevented from overflowing, and the possibility that the needle head is bent and punctured is further avoided.

Preferably, the connecting rope 8 is an elastic rubber string, when the infusion apparatus is not used, the connecting rope 8 is in a tensioned state, that is, when the infusion apparatus is not used, the puncture-proof sleeve 1 cannot automatically separate from the needle under the action of the elastic force to cause a needle puncture risk, and when the puncture-proof sleeve 1 is needed, only a small amount of pulling force is applied to remove the exposed needle for infusion.
