Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and/or" as it appears throughout includes three parallel schemes, for example "A and/or B", including the A scheme, or the B scheme, or the scheme where A and B are satisfied simultaneously. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be regarded as not exist and not within the protection scope of the present application.

Referring to fig. 1 to 2, the embodiment of the present application provides a safety type infusion needle, which includes a needle body 100, a protective tube 200 and a needle cap 400, wherein the needle body 100 includes a needle head 101, a needle seat 102 and a wing 103 as in the conventional intravenous needle, and the needle head 101 and the wing 103 are fixed on the needle seat 102.

The protection tube 200 is a hollow tube body, a through hollow inner cavity is formed in the protection tube 200 along the axial direction of the protection tube, the inner diameter of the hollow inner cavity is the same as the outer diameter of the needle seat 102, and the protection tube 200 can be matched and sleeved on the needle seat 102 and slide back and forth on the needle seat 102.

In one embodiment, in order to avoid the obstruction of the fins 103 and ensure the smooth movement of the protection tube 200, referring to fig. 3, the outer wall of the protection tube 200 is provided with a long and narrow avoidance groove 300 along the axial direction, and the fins 103 penetrate through the protection tube 200 from inside to outside through the avoidance groove 300. The width of the escape groove 300 is the same as the thickness of the fin 103, and thus the escape groove 300 restricts the fin 103 and prevents the needle body 100 from rotating relative to the protective tube 200. It is not inconceivable that the protection tube 200 can be freely moved back and forth without being blocked by the design of the escape groove 300. Of course, in one embodiment, referring to fig. 3, in order to prevent the protection tube 200 from being separated from the needle holder 102, baffles integrally formed with the protection tube 200 are provided at both side ends of the avoidance groove 300 to limit the sliding limit position of the protection tube 200 and prevent the needle holder 102 from sliding out of the protection tube 200.

In this embodiment, referring to fig. 1, the needle cap 400 is detachably sleeved on the protection tube 200, specifically, referring to fig. 3, the protection tube 200 includes a protection tube section 201 and a connection tube section 202, the avoidance groove 300 extends from the protection tube section 201 to the connection tube section 202, and the length of the avoidance groove 300 on the connection tube section 202 is greater than the width of the wing piece 103, so that when the wing piece 103 slides to the connection tube section 202, a space can be reserved for fixing the needle cap 400. The inside diameter of the protective sleeve pipe section 201 is the same as the outside diameter of the needle seat 102, the protective sleeve pipe section 201 is sleeved on the needle seat 102, the protective sleeve pipe section 202 slides back and forth along the needle seat 102, the protective sleeve pipe section 202 is integrally formed at the tail end of the protective sleeve pipe section 201, the inside diameter of the protective sleeve pipe section 202 is the same as the inside diameter of the protective sleeve pipe section 201, the outside diameter of the protective sleeve pipe section 202 is larger than the outside diameter of the protective sleeve pipe section 201, one end of the protective sleeve pipe section 202, which is close to the protective sleeve pipe section 201, is provided with an external thread 203, the inside diameter of the needle cap 400 is the same as the outside diameter of the protective sleeve pipe section 202, one end inner wall of the needle cap 400 is provided with an internal thread 401 matched with the external thread 203, the other end of the needle cap 400 is sealed, the needle cap 400 is sleeved on the protective sleeve pipe section 201 and is in threaded connection with the protective sleeve pipe section 202, and the needle cap 400 can form sealing protection for the needle body 100 when the needle body 100 is not used.

As can be seen from the above, the usage method and working principle of the safety infusion needle provided in the embodiments of the present application are as follows:

when the infusion needle is required to be used, the cap 400 is first unscrewed from the protective tube 200, and then the protective tube 200 is pinched and moved backward, so that the needle body 100 is exposed out of the protective tube 200, and venipuncture can be performed. After the transfusion is finished, the needle body 100 is withdrawn out of the vein, if the sharp instrument box is not beside the medical staff at the moment, the medical staff can cover the needle body 100 by moving the protective tube 200 forwards, so that the danger of injuring the staff by mistake caused by the naked placement of the needle body 100 can be avoided, the design based on the protective tube 200 is described from the side, and the trouble that the medical staff needs to carry the sharp instrument box every time is avoided. In addition, it should be understood that, in order to avoid the exposure of the needle body 100, the needle cap 400 is used to re-cover the needle body 100 in the conventional method, but since the needle body 100 and the needle cap 400 are relatively small, when the needle cap 400 is covered on the needle body 100, the hand is easy to be pricked, so that the occurrence of such a situation can be avoided through the design of the protection tube 200.

The foregoing description of the preferred embodiments of the present application is not intended to limit the utility model to the particular embodiments of the present application, but to limit the scope of the utility model to the particular embodiments of the present application.
