Description
TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field especially relates to a prevent blood taking needle of falling off and prevent. BACKGROUND
[0002] Blood taking needle is a kind of instrument for collecting blood sample in medical examination process, and the commonly used blood taking needle of prior art is mostly split type blood taking needle, and its structure is that a blood collecting needle is connected to the tail end needle seat of the hose of intravenous infusion needle. When using, the blood collecting needle needs to be rotated and fixed at the front end of the needle holder outer cylinder, the intravenous puncture needle is held by hand to implement puncture to the vein, after success, the vacuum blood collection tube is inserted into the rear end cavity of the needle holder, the blade of the blood collecting needle penetrates through the blood blocking sleeve and pierces into the vacuum tube rubber plug, under the action of negative pressure, the blood is absorbed into the blood collection tube. When needed, repeat the above process, and multiple tubes of blood can be collected. After blood collection, the intravenous puncture needle is pulled out, local hemostasis is performed, the blood taking needle is taken off from the needle holder, and the intravenous puncture needle is discarded in the waste box.
[0003] In the production process of the split type blood taking needle of prior art, glue needs to be coated for sealing when the intravenous needle is connected with the catheter, but in the actual coating operation, glue overflow is prone to occur, thereby blocking the catheter, and the connection mode between the catheter and the insertion end is mostly still the insertion mode, and the intravenous needle is prone to falling off during use.
[0004] Based on the above reasons, the present design provides a prevent blood taking needle of falling off and prevent. SUMMARY
[0005] The utility model discloses a prevent blood taking needle of falling off and prevent.
[0006] To achieve the above object, the utility model is through such technical scheme to realize, a prevent blood taking needle of falling off and prevent, including blood taking needle, the blood taking needle is butterfly type blood taking needle, the blood taking needle includes intravenous needle and catheter, the catheter is inserted with the end of the intravenous needle and is handled with the insertion of glue, and the insertion of the catheter with the intravenous needle is provided with recess, the recess is annular distribution, the recess extends the catheter and is all cone shape arrangement.
[0007] Further, the upper end of the catheter is also provided with a bottle insertion end, the bottle insertion end is connected with the catheter through threads, and the upper end of the bottle insertion end is provided with a needle insertion end.
[0008] Further, the left and right ends of the blood taking needle are provided with butterfly type plates.
[0009] The utility model is through the recess of annular distribution at the insertion of the catheter and intravenous needle, prevents the overflow of glue in the process of coating and blocks the catheter or intravenous needle, greatly improves the yield of production, and also prevents accidental falling off in the actual use process through the threaded connection between the catheter and the insertion end, influences use. BRIEF DESCRIPTION OF DRAWINGS

[0012] In the figure: 1, blood taking needle; 101, venous needle; 2, catheter; 3, bottle insertion end; 4, needle insertion; 5, butterfly plate; 6, recess. DETAILED DESCRIPTION
[0013] The utility model will be further clearly and completely explained in conjunction with the drawings of the specification, but the protection scope of the utility model is not limited to this. EMBODIMENT
[0014] As Figures 1 to 2 It is shown in the figure, a kind of blood taking needle of anti-dropping and anti-blocking, including blood taking needle 1, the blood taking needle 1 is butterfly blood taking needle, the blood taking needle includes venous needle 101 and catheter 2, the catheter 2 is connected with the end of the venous needle 101 and is coated with glue at the insertion, and the insertion of the catheter 2 and the venous needle 101 is provided with recess 6, the recess 6 is annularly distributed, the recess 6 extends the catheter 2 and is integrally conical, by setting recess 6, for storing overflow glue, avoid the overflow glue produced in production process to cause the catheter 2 or venous needle 101 to be blocked at the insertion of catheter 2 and venous needle 101.
[0015] In the embodiment, the upper end of the catheter 2 is further provided with bottle insertion end 3, the bottle insertion end 3 is connected with the catheter 2 by screw thread, the screw thread connection avoids that bottle insertion end 3 and catheter 2 are connected and fall off in use process, and the upper end of the bottle insertion end 3 is provided with needle insertion 4.
[0016] In the embodiment, the left and right ends of the blood taking needle 1 are provided with butterfly plate 5, and the setting of butterfly plate 5 can make the user better grip, so that the needle insertion angle is better grasped, and the pain in the blood taking process is reduced.
[0017] The embodiment of the utility model discloses the preferred embodiment, but is not limited to this, and the ordinary skill in the art, the spirit of the utility model is easily understood according to the above-mentioned embodiment, and different induction and change are made, but as long as not departing from the spirit of the utility model, it is within the protection scope of the utility model.
