One side of the limit plate 23 is in contact with the pen cap 2, and the limit plate 23 is perpendicular to the central axis of the pen cap 2. The pressure sensor 24 is located on the outside of one of the limit plates 23. When the patient's fingertip is aligned with the through slot 21, the pressure of the fingertip on the pressure sensor 24 can make the pressure sensor 24 sense the patient's fingertip and transmit the signal to the processor 14. The processor 14 controls the ejector 11 to eject the blood collection needle. Ejection, reduce the patient's fear, so that the patient can insist on self-testing of blood sugar, the inner side of the through groove 21 is movably connected with a needle tip protection component 3, through which the needle tip can be wrapped during withdrawal, thereby isolating the needle tip from the pen cap 2, and avoiding the needle tip from contacting with blood and causing contamination to the inside of the pen cap 2, the needle tip protection component 3 includes a connecting ring 31, a movable ring plate 32 and a silicone layer 33, the connecting ring 31 matches the size of the through groove 21, when the connecting ring 31 enters the inner side of the through groove 21, the outer arc surface of the connecting ring 31 is tightly attached to the inner side of the through groove 21, the inner side of the connecting ring 31 is movably connected with an annular plate 312, the sliding direction of the annular plate 312 is parallel to the connecting ring 31, and the movable ring plate 32 The ring plate 312 is connected to the ring plate 312 through a PVC film 313. The movable ring plate 32 is located on the side of the connecting ring 31 away from the limiting plate 23. The needle tip protection component 3 can be limited by the limiting plate 23. The PVC film 313 is a deformable elastic film and also has a certain adsorption property. The silicone layer 33 is fixedly connected to the inner side of the movable ring plate 32, and a through hole 331 is provided on the silicone layer 33. Since the silicone layer 33 is an elastic and deformable material and the size of the through hole 331 is smaller than the size of the needle, when the needle pops out, the needle will pass through the inside of the through hole 331 and expand the through hole 331. Since the limiting plate 23 can limit the connecting ring 31, the silicone layer 33 will not interfere with the ejection of the needle.Since the friction between the silicone layer 33 and the needle is greater than the friction between the annular plate 312 and the connecting ring 31 and the friction between the connecting ring 31 and the pen cap 2, when the needle is withdrawn, the silicone layer 33 and the movable ring plate 32 will move with the needle toward the pen bolt 1, and the movable ring plate 32 will pull the PVC film 313 outward when moving, so that it wraps around the needle tip, thereby achieving the purpose of isolating the needle tip from the pen cap 2. When the pen cap 2 and the pen bolt 1 are disassembled and the blood collection needle is removed, it can also prevent the blood collection needle from being exposed to the outside and causing damage to the pen cap 2 and the patient's skin. The blood collection needle can be automatically ejected through the sensing of the processor 14, which is conducive to reducing the patient's fear and enabling the patient to insist on self-testing of blood glucose. The needle tip protection component 3 can wrap the blood collection needle when it pierces the skin and is withdrawn, thereby achieving the purpose of isolating the needle tip from the pen cap 2 and preventing the needle tip from contacting the blood from contaminating the inside of the pen cap 2.

A test strip can be connected to the test strip connection slot 121 , so that the blood glucose meter 12 can measure the patient's blood glucose index.

[0019] Two connecting shafts 22 are provided at one end of the pen cap 2 away from the pen bolt 1 , and the limiting plate 23 is rotationally connected to the connecting shafts 22 via a damper; the connecting ring 31 can be limited or given way by the rotation of the limiting plate 23 .

[0020] A through groove 311 is provided inside the connecting ring 31, and the annular plate 312 is slidably connected inside the through groove 311, and a limit block 314 is provided on the inner side of the through groove 311; the inner diameter of the limit block 314 is smaller than the size of the annular plate 312, so the limit block 314 can limit the annular plate 312.

[0021] A fixed plate 321 is provided on one side of the movable ring plate 32, and the PVC film 313 is fixedly connected to the ring plate 312 and the fixed plate 321 respectively; when the distance between the movable ring plate 32 and the connecting ring 31 increases, the movable ring plate 32 will drive the PVC film 313 and the ring plate 312 to move.

[0022] The working principle and use process of the present invention are as follows: when in use, first, the unused needle tip protection assembly 3 needs to be inserted into the inner side of the through groove 21, and the movable ring plate 32 needs to be located on the side of the connecting ring 31 away from the limiting plate 23, and then the two limiting plates 23 need to be rotated to limit the connecting ring 31, and then the pen cap 2 needs to be removed, and the blood collection needle needs to be connected to the blood collection needle mounting seat 15, and then the pen cap 2 needs to be connected to the pen bolt 1, so that the blood collection operation can be performed. When the end of the pen cap 2 is aligned with the patient's fingertip, and when the patient's fingertip is aligned with the through groove 21, the pressure of the fingertip on the pressure sensor 24 can make the pressure sensor 24 sense the patient's fingertip and transmit the signal to the processor 14. The processor 14 controls the ejector 11 to eject the blood collection needle, so that the blood collection needle pierces the patient's skin. When the needle pops out, the needle will pass through the inner side of the through hole 331 and expand the through hole 331. Since the limiting plate 23 can limit the connecting ring 31, the silicone layer 33 will not interfere with the ejection of the needle. Since the friction between the silicone layer 33 and the needle is greater than the friction between the annular plate 312 and the connecting ring 31 and the friction between the connecting ring 31 and the pen cap 2, when the needle is retracted, the silicone layer 33 and the movable ring plate 32 will move with the needle toward the pen bolt 1, and the movable ring plate 32 will pull the PVC film 313 outward when moving, so that it is wrapped around the needle tip.
