[0029] The present application embodiment discloses a needle with biological detection function. Figure 1 - Figure 4 A needle with biological detection function, comprising a needle tube 1; a positioning connection component 2 is fixedly installed on the edge of the needle tube 1, and the positioning connection component 2 comprises a connecting head 201, a fixing block 204, a connecting rod 205 and a detection head 206;

[0030] A slow-flow guide assembly 3 is fixedly installed on the inner side of the needle tube 1 , and the slow-flow guide assembly 3 includes a threaded leaf 301 .

[0031] Reference Figure 1 , Figure 2 and Figure 3 , the positioning connection assembly 2 also includes a clamping ring 202, a sealing ring 203 and a pull ring 207;

[0032] The inner edge of the needle tube 1 is slidably connected to the outer side of the connecting head 201, the outer edge of the connecting head 201 is fixedly connected to the inner side of the clamping ring 202, the outer side of the clamping ring 202 is clamped and connected to the inner side of the needle tube 1, so that the position of the connecting head 201 after movement can be fixed, one end of the needle tube 1 is fixedly connected to one side of the sealing ring 203, the outer side of the sealing ring 203 is extruded and connected to the inner side of the connecting head 201, so that the connection between the needle tube 1 and the connecting head 201 can be sealed, the inner edge of the connecting head 201 is fixedly connected to the outer side of the fixing block 204, one side of the fixing block 204 is fixedly connected to one end of the connecting rod 205, and the other end of the connecting rod 205 is fixedly connected to the outer side of the detection head 206, the connecting rod 205 and the detection head 206 are both slidably connected to the inner side of the needle tube 1, so the moving directions of the connecting rod 205 and the detection head 206 can be limited, and the outer edge of the needle tube 1 is fixedly connected to the inner side of the pull ring 207.

[0033] Reference Figure 1 and Figure 4 , the slow flow guide assembly 3 also includes a guide plate 302;

[0034] The inner end of the needle tube 1 is fixedly connected to the outer side of the threaded leaf 301, and the inner edge of the needle tube 1 is fixedly connected to the outer side of the guide plate 302. The threaded leaf 301 is located on one side of the guide plate 302, which can slow down the flow speed of blood inside the needle tube 1. A groove is provided in the middle of the top of the guide plate 302, which can limit the flow direction of the blood. The top of the guide plate 302 contacts the outer side of the detection head 206, which can limit the position of the detection head 206.

[0035] Working principle: The staff moves the connecting head 201, which can move the position of the fixed block 204 fixedly installed on the inner side of the connecting head 201. During the movement of the fixed block 204, the fixed connection between one side of the fixed block 204 and the connecting rod 205 can move the position of the detection head 206 fixedly connected to one end of the connecting rod 205. During the movement of the detection head 206, the detection head 206 is slidably connected to the inner side of the needle tube 1, so that the moving direction of the detection head 206 can be limited. When the detection head 206 moves to a suitable position, the clamping ring 202 fixedly installed on the outer side of the connecting head 201 is clamped to the inner side of the needle tube 1, so that the position of the moving connecting head 201 can be fixed. At this time, the end of the needle tube 1 is connected to the inner side of the needle tube 1. One side of the sealing ring 203 fixedly installed on the inside is squeezed against the outside of the connecting head 201, so as to seal the connection between the needle tube 1 and the connecting head 201, thereby completing the installation of the connecting head 201. At this time, the guide plate 302 fixedly installed on the inside of the needle tube 1 contacts the outside of the detection head 206, so as to support and limit the detection head 206. Finally, when the needle tube 1 draws blood from the user, the threaded leaf 301 fixedly installed on the inner end of the needle tube 1 can slow down the flow speed of the blood on the inside of the needle tube 1. Afterwards, the guide plate 302 fixedly installed on the inside of the needle tube 1 can divert the blood, so as to make the blood contact with the detection head 206, and the blood can be detected through the detection head 206.
