Description

Technical Field

[0001] This utility model relates to the field of medical testing tools, specifically to a portable blood collection card for rapid detection of vitamin K2 serum concentration. Background Technology

[0002] Vitamin K2 is a fat-soluble vitamin containing a methylnaphthoquinone structure, mainly distributed in extrahepatic tissues such as the kidneys, pancreas, bones, reproductive organs, and blood vessel walls. Vitamin K2 is an important and essential vitamin for the human body. Studies have shown that, in addition to its basic blood clotting function, vitamin K2 participates in the metabolism and regulation of bone and calcium in the body, playing an indispensable fundamental role in promoting and maintaining bone health. Therefore, quantitative detection of vitamin K2 concentration in human serum has significant clinical implications.

[0003] A blood collection card is a tool used to preserve blood samples. Collecting and preserving human serum using blood collection cards for subsequent testing is a common medical testing method, primarily suitable for centralized batch testing. However, its application to vitamin K2 concentration testing presents the following problems: Before vitamin K2 concentration testing, blood samples must be preserved at a low temperature. For batch testing, existing blood collection cards can be used to preserve blood samples, with each card placed sequentially in a cold box for storage, and then the cold box transported to the laboratory. However, when individual blood samples are collected using blood collection cards and need to be sent to the laboratory individually for rapid testing, the cold box transfer method is cumbersome and extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a portable blood collection card for rapid detection of vitamin K2 serum concentration that has a reasonable structure and reliable use, which solves the above-mentioned problems. Compared with existing blood collection cards, it not only has the function of preserving blood samples, but also the function of maintaining low temperature, thereby ensuring the preservation requirements before vitamin K2 concentration detection, improving detection accuracy, and is convenient to carry and suitable for rapid individual testing.

[0005] The technical solution of this utility model is:

[0006] A portable blood collection card for rapid detection of vitamin K2 serum concentration includes a card shell and a blood collection strip disposed within the card shell. The key technical features are: the card shell is rectangular with a side opening; the card shell contains an upper support cavity corresponding to the blood collection strip and a cooling material cavity located below the upper support cavity; a support shoulder is provided between the upper support cavity and the cooling material cavity; the blood collection strip has a blood collection cavity; the upper surface of the blood collection strip has a blood injection component communicating with the blood collection cavity; the lower surface edge of the blood collection strip is supported on the upper surface of the support shoulder; a large through hole is provided in the middle of the lower surface of the blood collection strip; a leak-proof protective membrane is affixed to the inner bottom surface of the blood collection strip to seal the large through hole; a packaging bag is provided in the cooling material cavity; the packaging bag contains cooling gel for bonding with the blood collection strip and the lower surface of the leak-proof protective membrane.

[0007] The aforementioned portable blood collection card for rapid detection of vitamin K2 serum concentration includes a reduced conical cap, a blood injection port connected to the center of the reduced conical cap, a transfusion tube connected to the blood injection port, and a blood collection needle connected to the transfusion tube. The reduced conical cap is fixed to the middle of the upper surface of the blood collection strip.

[0009] The portable blood collection card for rapid detection of vitamin K2 serum concentration described above has a damping layer on the two inner walls of the upper support cavity of the card shell to increase the friction with the blood strip and prevent them from coming loose.

[0010] The aforementioned portable blood collection card for rapid detection of vitamin K2 serum concentration has a pull-out plate on one side of the outer wall of the blood collection strip. The pull-out plate has a cap that matches the opening side of the card case. The upper surface of the end of the pull-out plate has a corrugated anti-dislodgement surface that facilitates pulling.

[0011] The beneficial effects of this utility model are:

[0012] Staff use a blood injection device to draw blood into the storage chamber, then attach cooling gel to the storage strip and the lower surface of the impermeable protective membrane. The thin membrane facilitates rapid heat exchange, achieving low-temperature preservation of the blood. Compared to existing blood collection cards, this method not only preserves blood samples but also maintains a low temperature, ensuring the preservation requirements for vitamin K2 concentration testing and improving accuracy. It is also portable and suitable for rapid, individual testing. Attached Figure Description
