Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, blood can be collected into different containers through the mutual matching of the butterfly needle, the blood collection tube and the puncture needle, the puncture of the butterfly needle can be kept at a proper angle through the arranged blood collection tube, and the butterfly needle is not required to be pulled out when the container is replaced, so that the pain of a patient is reduced, and meanwhile, the blood collection tube is applicable to blood collection containers with different volumes and sizes through the arranged protective cover and the clamping mechanism, and the protection of medical staff is improved.
Drawings
FIG. 1 is a schematic view showing the whole structure of a lancet for convenient use according to the present utility model;
fig. 2 is a schematic view of a sectional view of a lancet for convenience in use.
In the figure:
11. a butterfly needle; 12. a blood collection tube; 13. a puncture needle; 20. a protective cover; 31. a clamping plate; 32. pulling blocks; 33. a pull rod; 34. and (3) a spring.
Detailed Description
The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.
Example 1
Referring to fig. 1-2, the convenient-to-use blood taking needle provided by the utility model comprises a butterfly needle 11, wherein a blood taking tube 12 is fixedly connected to a liquid outlet of the butterfly needle 11; wherein, heparin tube 12 is the hose, adopts heparin tube 12 to make butterfly needle 11 nimble removal, and then the puncture angle of adjustable butterfly needle 11.
A puncture needle head 13 is fixedly arranged at one end of the blood collection tube 12 far away from the butterfly needle head 11, a shield 20 is fixedly arranged at the end part of the outer wall of the blood collection tube 12 close to the puncture needle head 13 (the shield 20 is made of transparent materials), and the puncture needle head 13 is positioned in the shield 20; wherein, can protect medical personnel through the protection casing 20 that sets up, avoid inserting the puncture needle 13 to the in-process of blood sampling container by the stab.
The protective cover 20 is provided with a clamping mechanism for fixing the blood collection container; wherein, through the clamping mechanism who sets up can guarantee the stability between blood sampling container and the pjncture needle 13, avoid drawing the time spent because and draw and lead to pjncture needle 13 slippage from blood sampling container, the follow-up operation of playing the needle of being convenient for.
The clamping mechanism comprises two clamping plates 31 (the clamping plates 31 are transparent arc plates), two pull rods 33 are symmetrically arranged on the outer wall of the protective cover 20, the pull rods 33 movably penetrate through the side wall of the protective cover 20, the end walls of the two pull rods 33 are respectively and fixedly connected to the outer wall of the clamping plates 31, one end, far away from the clamping plates 31, of each pull rod 33 is fixedly connected with a pull block 32, a spring 34 is sleeved outside the pull rod 33, and two ends of each spring 34 are respectively and fixedly connected to the outer wall of the clamping plates 31 and the inner wall of the protective cover 20; when the puncture needle 13 is inserted into the blood collection container, the index finger and the thumb of one hand can be respectively inserted into the annular grooves of the two pull blocks 32, then the two pull blocks 32 are moved in the direction away from each other, the two pull rods 33 and the two clamping plates 31 are driven to move in the direction away from each other, then the blood collection container is inserted into the puncture needle 13, the index finger and the thumb are moved out of the pull blocks 32, and at the moment, the two clamping plates 31 fix the blood collection container under the action of the elasticity of the two springs 34, so that the subsequent needle lifting operation is facilitated.
