Description

Technical Field

[0001] The utility model belongs to the technical field of medical consumables, and in particular relates to a blood sugar collection needle. Background Art

[0002] The most accurate way to check blood sugar is through intravenous blood sugar monitoring, which requires going to the hospital to draw blood, and then sending the blood to the hospital laboratory for testing. In addition, there are also some ways to test blood sugar by yourself.

[0003] There are many blood glucose test strips on the market, which are equipped with blood collection needles. The handle of the blood collection needle is made of flat plastic material, and the bottom is an exposed needle. At the same time, there is a protective cap on the needle, which is integrated with the bottom of the needle handle. When using, just unscrew the protective cap. After use, just discard the test strip, protective cap and needle handle together. Although this type of blood collection needle has a simple structure, the needle is always exposed after being discarded, which is dangerous. In addition, there are some blood collection needles with complex structures, which have built-in springs. After use, they are retracted by the spring, but this type of blood collection needle is expensive and not easy to promote in large quantities. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a blood glucose collection needle to solve the above technical problems.

[0005] The utility model adopts the following technical solutions:

[0006] The blood glucose collection needle comprises a shell and a needle handle. The shell has slide grooves on both sides. The needle handle is installed between the slide grooves. A needle head is provided at the bottom of the needle handle. The needle head is located in the shell. The upper part of the shell is also connected to a flip cover by a rotating shaft. The bottom of the flip cover has a protrusion. The front of the shell has an opening that matches the shape of the flip cover, and the flip cover is buckled with the shell.

[0007] Furthermore, the back side of the shell has an escape opening corresponding to the protrusion.

[0008] Furthermore, a clamping point for clamping with a side edge of the flip cover is formed on the inner side of the top of the shell.

[0009] Furthermore, the bottom of the shell has a countersunk groove facing the needle position.

[0010] Furthermore, the front side of the needle handle has convex patterns.

[0011] Furthermore, the top of the flip cover is provided with a hook, the front of the shell is provided with a buckle groove, and the hook is locked into the buckle groove.

[0012] The beneficial effects of the utility model are as follows: in this structure, when in use, it is only necessary to open the flip cover and rotate it to a vertical state, the protrusion contacts the top of the needle handle, and during the rotation of the protrusion, a downward squeezing force is generated on the needle handle, so that the needle can directly pass through the bottom of the shell, and then the subsequent finger-pricking blood collection process can be carried out. After use, the flip cover is put back, and before it is completely buckled, the needle handle can be retreated into the shell by its own gravity, or by slightly manually pushing the needle handle back, and finally the flip cover is completely buckled. There is pressure on the front of the flip cover and the needle handle, and the needle handle will not slide in the shell. This makes it convenient to recycle the blood collection needle, and the needle will not be exposed, thereby ensuring safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0018] like Figure 1-3 As shown, the blood glucose collection needle provided in this embodiment includes a shell 1 and a needle handle 2. The shell 1 has slide grooves 11 on both sides. The needle handle 2 is installed between the slide grooves 11. The needle handle 2 is provided with a needle head 3 at the bottom, and the needle head 3 is located in the shell 1 (the figure shows a schematic diagram of the use state, and the needle head is exposed from the shell after use). The upper part of the shell 1 is also connected to a flip cover 4 with a rotating shaft. The bottom of the flip cover 4 has a convex block 41. The front of the shell 1 has an opening 12 that matches the shape of the flip cover, and the flip cover 4 is buckled with the shell 1. After buckling, the flip cover can press the needle handle tightly, and the needle handle will not slide in the shell, so as to prevent the needle from piercing the shell. In order to ensure the extrusion force, the front of the needle handle 2 has a convex pattern 21, and the convex pattern 21 generates extrusion and friction with the flip cover.

[0019] As shown in the figure, a hook 42 is provided on the top of the flip cover 4 , and a buckle groove 10 is provided on the front side of the housing 1 , and the hook 42 is locked into the buckle groove 10 .

[0020] When it needs to be used, open the flip cover and turn it. The protrusion at the bottom of the flip cover turns with the flip cover until it turns to a vertical position. During the rotation, the protrusion first contacts the top of the needle handle, and then during the continued rotation, the protrusion exerts a downward squeezing force on the needle handle, so that the needle can directly pass through the bottom of the shell. Finally, you can directly prick your finger with the needle. After taking it out, squeeze the finger to complete the blood sugar collection and use a blood sugar test strip to test the blood sugar.

[0021] In order to ensure that the flip cover remains stable during use, a clamping point 13 is formed on the inner side of the top of the housing 1 for clamping with the side edge of the flip cover 4. When the flip cover is rotated to a vertical state, the sides of the flip cover are squeezed with the clamping point, resulting in a slight deformation, forming a squeezing force on both sides of the flip cover, which can prevent the flip cover from rotating accidentally. In addition, the protrusion is a discrete arc, and the back of the housing 1 has an avoidance opening 14 corresponding to the protrusion 41.

[0022] After use, put the flip cover back on, and before it is completely buckled, the needle can be retracted into the shell by the gravity of the needle handle or by slightly manually pushing the needle handle back (of course, you can also directly use the desktop to push the needle back into the shell. The friction between the needle handle and the shell slide groove is very small, and it can even slide freely. Place the bottom of the shell on the desktop and the needle will automatically retract). Finally, completely buckle the flip cover. There is pressure on the front of the flip cover and the needle handle, and the needle handle will not slide in the shell. This makes it convenient to recycle the blood collection needle, and the needle will not be exposed, ensuring safety.

[0023] Finally, a countersunk groove 15 is provided at the bottom of the shell 1 facing the needle to reduce the thickness of the shell facing the needle, so that the needle can easily pass through the bottom of the shell after the flip cover is opened.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
