Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to a diabetes detection and analysis instrument. Background Art

[0002] Diabetes detection analyzers are currently commonly used blood sugar testing devices. With the development of technology, diabetes detection analyzers are becoming smaller and smaller, more and more accurate, and are widely used in homes and hospitals. At present, diabetes detection analyzers can be divided into fixed type (i.e., instruments collected at fixed locations), wearable type (i.e., instruments worn on the body that can perform dynamic detection), and portable type (i.e., instruments that are easy to carry) according to different usage scenarios. Among them, portable diabetes detection analyzers are very commonly used due to their low cost and convenience to carry. For example, the Yuyue 590 blood glucose meter currently on the market is used by inserting the test strip into the test strip socket of the blood glucose meter, pricking the finger with a blood collection nose, and squeezing the blood onto the test strip.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention can integrate detection, blood collection and storage by fixing the blood collection pen and the storage slot on the left side wall of the blood glucose analyzer, so as to achieve the effect of completing blood glucose detection in one stop, which is convenient for carrying and can avoid the situation that one or more of the blood collection needle, blood collection pen, test paper and blood glucose analyzer are not taken or missed, thereby ensuring that the blood glucose detection can be carried out on time.

[0017] 2. The present invention drives the slider, the elastic sheet and the card block to move upward along the guide rod as a whole and compress the spring by moving the toggle block upward until the card block moves to the through groove. Under the force of the elastic sheet, the card block will be stuck in the through groove, thereby fixing the position of the slider, and when the user presses the elastic pad, the fixed block will push the card block out of the through groove. At this time, the restriction of the slider is released, so it will move downward under the elastic force of the first spring and push or impact the blood collection needle, so that the blood collection needle moves downward and pierces the patient's finger. After that, the elastic force of the second spring causes the needle pierced into the patient's finger to withdraw and retract into the placement tube, thereby realizing the effect of automatic needle withdrawal and achieving the purpose of blood collection.

[0018] 3. The used blood collection needle in the present invention is not only independently placed in the placement tube, but also has no connection with the firing mechanism. When taking out the blood collection needle, one only needs to remove the placement tube and invert it to remove the used blood collection needle without contact. The used blood collection needle is completely hidden in the placement tube. Therefore, compared with the traditional blood collection pen that needs to be manually removed after use, it is safer, especially when the needle cap or needle cover is lost.

[0019] 4. The present invention prevents the needle tip of the blood collection needle from being directly exposed to the air through the blood collection needle cover, thereby improving the safety when removing the needle. When withdrawing the needle, the blood collection needle can be pushed out of a part of the blood collection pen cap by the fixed rod by pushing the toggle block downward, so that the blood collection needle cover can be put on the blood collection needle after use, thereby further improving the safety of needle withdrawal.

[0020] 5. The present invention rotates the blood collection pen cap so that the shift plates of different heights are rotated to just below the limit plate. When the blood collection needle is impacted by the fixed rod and moves downward, it can only move to the position where the limit plate contacts the corresponding shift plate. Since the position of the blood collection needle is fixed after placement, the shift plates of different heights are rotated to just below the limit plate to adjust the maximum moving distance of the blood collection needle, and further the depth of the needle penetrating the patient's finger can be adjusted to accommodate blood collection from patients of different body shapes.
