AI Technical Summary
During the discarding process of existing blood collection needles after use, the needle end lacks effective protection, which can easily cause harm and contamination to the operator.
A safe anti-acupuncture blood collection needle is designed, adopting a butterfly blood collection needle, and a protective sleeve is connected to the catheter. The upper end of the protective sleeve is large and the lower end is small, and it is transitioned through a conical barrel. A guide groove is symmetrically arranged on the side wall of the lower end to jammed the blood collection needle to prevent injury.
After exiting the needle of the blood collection needle from the blood collection site, cover the protective cover of the entire blood collection needle, rotate the blood collection needle to the guide groove and get stuck and thrown into the trash can, effectively preventing the operator from being stabbed during the abandonment of the blood collection needle.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a safe anti-needle puncture blood collection needle. Background Art
[0002] The disposable blood collection needles used on a large scale in clinical practice in the prior art are split-type blood collection needles, which are structured such that a blood collecting needle is connected to the needle seat at the tail end of the hose of the intravenous infusion needle. When in use, the blood collecting needle needs to be rotated and fixed on the front end of the outer tube of the needle holder, and the vein is punctured by the hand-held venous puncture needle. After success, the vacuum blood collection tube is inserted into the rear end cavity of the needle holder, so that the cutting edge of the blood collecting needle passes through the blood blocking sleeve and pierces the vacuum tube plug. Under the action of negative pressure, blood is sucked into the blood collection tube. When necessary, this process is repeated to achieve multi-tube blood collection. After blood collection is completed, the venous puncture needle is pulled out, local bleeding is stopped, the blood collection needle is removed from the needle holder, and discarded in a waste box together with the venous puncture needle.
[0003] However, in actual practice, when the blood collection needle is discarded after use, the needle end of the blood collection needle lacks effective protection, which can easily cause damage to the operator's hands and cause contamination.
[0004] Based on the above reasons, this design proposes a safe anti-needlestick blood collection needle. Summary of the invention
[0005] The utility model aims to provide a safe anti-needle-puncture blood collection needle.
[0006] To achieve the above-mentioned purpose, the utility model is implemented through such a technical solution, a safe anti-needlestick blood collection needle, including a blood collection needle, the blood collection needle is a butterfly-shaped blood collection needle, the upper end of the blood collection needle is connected to a catheter, a protective sleeve is sleeved on the catheter, the upper end of the protective sleeve is large and the lower end is small, the upper end and the lower end of the protective sleeve are transitioned by a conical barrel, and guide grooves are symmetrically arranged on the side wall of the lower end of the protective sleeve, the guide grooves are arranged in a side T-shape, and the long side length of the guide grooves is longer than the overall length of the blood collection needle.
[0007] Furthermore, the short side width of the guide groove is wider than the width of the blood collection needle.
[0008] Furthermore, the material of the protective cover is medical-grade plastic.
[0009] The utility model has the following steps: after the needle of the blood collection needle is withdrawn from the blood collection site, the protective cover is pulled downward so that the protective cover covers the entire blood collection needle, and the blood collection needle is rotated to the short side of the guide groove to be stuck and then thrown into a waste bin to wait for subsequent processing. Due to the presence of the protective cover, the operator can be prevented from being stabbed during the discarding and processing of the blood collection needle. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the utility model structure;
[0011] Figure 2 It is a schematic cross-sectional view of the utility model protective cover.
[0012] In the figure: 1. blood collection needle; 2. catheter; 3. protective cover; 4. upper end; 5. lower end; 6. conical barrel; 7. guide groove. DETAILED DESCRIPTION
[0013] The present invention is further explained in detail below in conjunction with the accompanying drawings of the specification, but the protection scope of the present invention is not limited thereto. Example
[0014] like Figure 1 to Figure 2 As shown, a safe anti-needlestick blood collection needle comprises a blood collection needle 1, wherein the blood collection needle 1 is a butterfly-shaped blood collection needle, wherein the upper end of the blood collection needle 1 is connected to a catheter 2, wherein a protective sleeve 3 is sleeved on the catheter 2, wherein the upper end 4 of the protective sleeve 3 is larger than the lower end 5, wherein a conical barrel 6 transitions between the upper end 4 and the lower end 5 of the protective sleeve 3, wherein guide grooves 7 are symmetrically arranged on the side wall of the lower end 5 of the protective sleeve 3, wherein the guide grooves 7 are arranged in a side T-shape, and wherein the long side length of the guide grooves 7 is longer than the overall length of the blood collection needle 1.
[0015] In this embodiment, the short side width of the guide groove 7 is wider than the width of the blood collection needle 1 .
[0016] In this embodiment, the material of the protective cover 3 is medical grade plastic.
[0017] Working principle:
[0018] After the operator completes the blood collection operation, after withdrawing the needle tip of the blood collection needle 1 from the blood collection site, he pulls the protective cover 3 downwards so that the protective cover covers the entire blood collection needle 1, and rotates the blood collection needle 1 to the short side of the guide groove 7 to lock the blood collection needle 1 and then throw it into a waste bin to wait for subsequent processing. Due to the presence of the protective cover 3, the operator can be prevented from being stabbed during the abandonment of the blood collection needle 1.
[0019] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Ordinary technicians in this field can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present utility model, they are all within the protection scope of the present utility model.
