After the blood returns in the extension tube, tear off the medical anti-allergic double-sided adhesive on the surface of the single-winged needle wing, so as to fix the single-winged needle wing on the skin surface of the blood sampler, and complete the fixing operation of the blood collection needle;

The user pinches the fixed cap with his fingers and inserts the blood collection tube into the fixed cap. At this time, the protective cover connected to the needle is squeezed, and the connected needle is pierced into the blood collection tube, and the blood flows into the blood collection tube from the extension hose;

After the blood collection is completed, the blood collection tube is pulled out from the fixed cap to complete the blood collection operation.

Compared with the prior art, the utility model sets a single-winged needle wing with a width greater than or equal to the length of the needle bar on the blood collection needle, so that the user can hold the single-winged needle wing stably and reliably when wearing double-layer gloves, and then The needle insertion operation is completed; by setting a fixed cap at one end of the extension hose, the fixed cap is set on the outside of the connecting needle, so that the user can quickly and stably hold the fixed cap while wearing double-layer gloves, so as to accurately insert the connecting needle The blood collection tube also plays the role of fixing the blood collection tube. Thus, the fast and reliable fixation of the blood collection needle and the blood collection tube is realized, so that medical workers can conveniently, efficiently and accurately perform blood collection operations while wearing double-layer gloves.

The utility model is provided with anti-slip raised lines on the end surface of the single-winged needle wing, and provided with anti-slip vertical stripes on the outer surface of the fixed cap, which can further increase the friction between the user's fingers and the single-winged needle wing and the fixed cap, and improve the operation stability.

The utility model is equipped with a deformable and telescopic protective sleeve outside the connecting needle, which can protect the connecting needle without affecting the connection needle piercing into the blood collection tube; in addition, the utility model is equipped with a medical Anti-allergic double-sided tape, after the needle is inserted, the double-sided tape can be torn off and directly attached to the skin surface of the blood-collected person. There is no need to prepare additional tape to fix the blood-collecting needle, which further saves operating time and improves blood-collecting efficiency.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example

As shown in Figure 1, a round-cap blood collection needle device includes a blood collection needle 1, the blood collection needle 1 is connected to one end of an extension hose 3 through a needle rod 2, and the other end of the extension hose 3 is connected to the needle for piercing a blood collection tube. The connecting needle 5 of 4 is connected with each other, the other end of the extension hose 3 is provided with a fixed cap 6, and the fixed cap 6 is set on the outside of the connecting needle 5, and the blood collection needle 1 is provided with a single-winged needle wing 7, and the single-winged needle wing The width of 7 is greater than or equal to the length of needle bar 2.

As shown in FIG. 2 , the end surface of the single-wing needle wing 7 is provided with anti-slip raised lines, and in addition, one side surface of the single-wing needle wing 7 is provided with medical anti-allergic double-sided adhesive tape.
