The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-6, an embodiment of the present utility model is provided: a sterile injection needle, which comprises a shell 1, wherein a needle tube 10 is arranged in the shell 1; a baffle 11 is arranged in the needle tube 10, and a plurality of needles 12 with consistent structures are also arranged on the outer end face of the needle tube 10; the outer wall surface of the needle tube 10 is provided with a bulge 15, and the inner wall surface of the shell 1 is provided with a chute 14; a fixed cover 3 is further arranged on the shell 1, and a drainage tube 32 is fixed in the shell 1 after the fixed cover 3 is connected with the shell 1; the side of the drainage tube 32 facing the baffle 11 is also provided with a flow dividing plate 34, and the medicament inside the drainage tube 32 is distributed to each needle 12 through the flow dividing plate 34.

In summary, since the needle tube 10 is provided with the plurality of needles 12, for example, when the number of needles 12 is 5; so that the device can synchronously realize synchronous injection of multiple points, and simultaneously, after the drainage tube 32 introduces the medicament, the medicament is led to each needle 12 by the splitter plate 34, so that the medicament can be uniformly injected to each point; meanwhile, the device is cylindrical in whole, so that the device is convenient for a user to hold, and particularly, the problem that the needle tube 10 axially rotates in the shell 1 can be solved by mutually matching the sliding groove 14 with the protrusion 15. In particular, the drainage tube 32 is fixed on the housing 1 by the fixing cover 3, so that the fixing cover 3 is disassembled to facilitate the separation of the fixing cover 3 and the housing 1, and further the cleaning of the interior of the housing 1 and the cleaning of the drainage tube 32 and the like are facilitated for a user.

In addition, since the seal ring is mounted on the outer wall surface of the needle tube 10, the internal cavity of the injection needle is sealed after the seal ring is mounted, the liquid return passage is blocked and positive pressure is formed during injection, and the liquid is forced to be completely injected into the skin, thereby preventing leakage.

Further, since the diversion trenches 30 are disposed on the opposite surfaces of the diversion plate 34 and the baffle 11, when the medicament enters the diversion trenches 30 of the diversion plate 34 and the baffle 11, more medicament can be contained in the space by using the space, so that the diversion trenches 30 can guide the medicament to enter the needle 12 and simultaneously perform a steady flow function.

Meanwhile, grooves 35 are formed in the outer circumferential surfaces of the baffle 11 and the flow dividing plate 34, and the grooves 35 are connected with positioning strips 16 formed in the inner wall surface of the needle tube 10 in a matching manner. This in turn prevents axial rotation of the shield 11 and the splitter plate 34 within the needle cannula 10.

On the basis of the scheme, the shell 1 is also provided with an outer cover 17; the housing 17 is provided with a connection port 13, and the connection port 13 is connected and communicated with the inside of the housing 17, so that after the negative pressure device is connected with the connection port 13 through a pipeline, the inside of the housing 17 can be promoted to form vacuum, and the skin of a user can be adsorbed.

Further, as the inside of the shell 1 is also provided with a baffle plate 19; wherein, the baffle 19 is provided with a mounting seat 110 for mounting the needle 12. Further, a limiting boss 18 is disposed in the mounting seat 110, and the receptacle 111 disposed on the baffle 11 is limited to move downward by the limiting boss 18.

In summary, the distance between the needle 12 can be limited, so that the problem of over-deep insertion of the needle 12 can be effectively avoided, and the limiting boss 18 can also make a sound when the socket 111 is impacted, so as to remind the user of ending the needle insertion action.

Since the cover 17 is further provided with the protective cover 2, the needle 12 can be protected by the protective cover 2.

Meanwhile, the fixed cover 3 is connected with an external thread 33 arranged on the drainage tube 32 in a matching way through an internal thread 31 arranged on the fixed cover, and the fixed cover 3 is matched with the shell 1 in a threaded way. Therefore, the position between the fixed cover 3 and the shell 1 and the drainage tube 32 after installation is stable and reliable, so that the reliable use of the equipment is ensured.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
