Examples:
as shown in fig. 1 to 5, in the present embodiment, there is described a double safety belt blood collection tube vein blood collection needle comprising a needle body 1, a needle holder 2, a connection hose 3, a needle penetration prevention sleeve 5, and a blood collection tube 6.
Wherein, needle body 1 installs on needle file 2, and needle body 1 one end is the puncture end, and the other end is non-puncture section, and the non-puncture end of needle body 1 links to each other with the one end of coupling hose 3.
The anti-needling sleeve 5 is sleeved on the outer side of the needle seat 2, the needle seat 2 can move along the inner side of the anti-needling sleeve 5, and after the needle is withdrawn, the needle seat 2 can drive the needle body 1 to be accommodated in the anti-needling sleeve 5.
The other end of the connecting hose 3 is provided with a joint, for example a conical joint 4. Correspondingly, the opening end of the blood collection tube 6 is provided with a silica gel valve 7 which is matched with the joint.
In the non-blood collection state, the blood collection tube 6 is sealed by the silicone valve 7.
In the preferred embodiment of the present utility model, the needle holder 2, the connection hose 3 and the needle penetration prevention cannula 5 may be made of transparent materials, so that the internal structure and the blood flow state can be conveniently observed.
The anti-needling cannula 5 can be made of hard materials, so that the needle body 1 is prevented from piercing the anti-needling cannula 5.
The connecting hose 3 is a hose made of a silica gel material.
In addition, the intravenous blood taking needle in the present embodiment further includes a first limit portion for preventing the needle holder 2 from moving forward after withdrawing the needle and a second limit portion for preventing the needle holder 2 from moving backward after withdrawing the needle.
The first limiting part comprises a limiting block 8 arranged on the inner side wall of the rear end of the anti-needling sleeve 5 and a limiting groove 9 arranged at the front end of the needle seat 2, as shown in fig. 4 and 5.
The limiting block 8 has certain elasticity, and when the limiting block 8 moves to the limiting groove 9, the limiting block 8 can be clamped into the limiting groove 9, and the limiting block 8 and the limiting block are matched and clamped with each other, so that the needle seat 2 can be prevented from moving forwards.
The second limiting part comprises a first limiting stop 10 arranged on the inner side wall of the rear end of the anti-needling sleeve 5 and a second limiting stop 11 arranged at the front end of the needle seat 2.
In the embodiment of the present utility model, the first limit stop 10 is a first annular protrusion, and the second limit stop 11 is provided as a second annular protrusion.
After the blood collection work is finished, the worker moves the needle penetration prevention sleeve 5 to store the needle body 1, and at the moment, the first annular protrusion is in clamping fit with the second annular protrusion, so that the needle seat 2 can be prevented from moving backwards.
In this embodiment, the number of the blood collection tubes 6 is 1, for example, and when blood collection is required, the blood collection operation can be conveniently performed by inserting the conical connector 4 into the silicone valve 7.
Because the blood collection tube 6 and the blood collection needle main body part are connected in a needleless way in the embodiment, the problem that medical staff is easy to be stabbed when the blood collection needle is used for penetrating the traditional blood collection tube in the traditional mode is well avoided.
Of course, the number of the blood collection tubes 6 in the embodiment is not limited to 1, and a plurality of blood collection tubes can be arranged according to the needs, for example, 2, 3, 4, 5 and other specifications can be selected clinically, so that multiple blood collection can be realized.

When the patient needs more samples to be collected, the blood collection tube 6 can be continuously replaced, the needle insertion and blood collection are not needed again, and the damage to medical staff caused by the exposed needle body 1 can be avoided.
The specific operation process of the utility model is as follows:
when blood collection is carried out, a worker inserts the conical connector 4 into the silicone valve 7, and the hand-held needle seat 2 pierces the puncture end of the needle body 1 into a blood collection part, and simultaneously opens the hemostatic clamp 12 to collect blood.
After the blood sampling work is finished, when the needle body 1 is pulled out, one hand of a worker holds the puncture-proof sleeve 5, the other hand holds the needle seat 2 to withdraw the needle, after the needle withdrawal is finished, the needle body 1 is completely contained in the puncture-proof sleeve 5, and meanwhile, the limit of the position of the needle seat 2 is realized through the first limit part and the second limit part, so that the needle body 1 cannot slide out from the puncture-proof sleeve 5 after the needle withdrawal is ensured.
When the patient needs more samples to be collected, the hemostatic clamp 12 can be closed, the blood collection tube 6 can be directly replaced, the needle insertion is not needed again for blood collection, and the damage to medical staff caused by the exposed needle body 1 can be avoided. By the above structure, double safety protection during the process of puncturing a patient and puncturing the blood collection tube 6 is realized.
The utility model can prevent the needle tube with blood from being exposed in the air and the medical staff from being pricked, thereby ensuring that the intravenous blood taking needle is safer to use and realizing double safety protection in the processes of puncturing patients and puncturing the blood taking tube 6.
The present embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art will clearly recognize that a double safety belt blood collection tube intravenous blood collection needle of the present utility model
Of course, the above-mentioned embodiments are only preferred embodiments of the present utility model, and not limiting the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model and should be protected by the present utility model.
