[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] To address the technical problem of blood collection cards failing to dry effectively and promptly after blood collection, this invention provides a blood collection card that enables timely and effective drying after blood collection.

[0033] Please see Figure 1 , Figure 1This is a three-dimensional structural diagram of a blood collection card according to an embodiment of the present invention. The blood collection card includes a collection card 1, a collection recess 2, a desiccant pad 3, and a collection cover 4. The collection recess 2 is disposed on the collection card 1 and protrudes downward from the bottom of the collection card 1. Ventilation holes 201 are formed on the outer periphery of the collection recess 2, and a blood collection ring 202 is provided on the inner bottom wall of the collection recess 2. Blood drips onto the blood collection ring 202 for collection. The ventilation holes 201 on the outer periphery of the collection recess 2 form an internal and external communication channel for air circulation and protect the blood collection ring 202 under the upper surface of the collection card 1. The desiccant pad 3 is disposed at the bottom of the collection recess 2 to absorb excess moisture from the collected blood. The desiccant pad 3 absorbs and dries the blood, improving drying efficiency. The collection cover 4 extends outward from one side of the collection card 1 and flips with the collection card 1 through the crease 101. It has a position where it is closed to the top of the collection card 1 and a position where it is open to the side of the collection card 1. Since the blood collection ring 202 has a concave design, after blood is collected, the top of the collection card 1 can be closed by the collection cover 4. At this time, the entire blood collection card can be placed in a sunny place. With the collection cover 4 closed, the sun will not directly dry the blood collection ring 202. Moreover, the protective effect of the blood collection ring 202 is improved by closing it. With the concave design and ventilation hole 201, it will not have too much impact on air circulation and moisture drying. It can still be effectively dried after closing.

[0034] Understandably, when the collection recess 2 is closed with the collection cover 4, it can prevent the collection cover 4 from contacting the blood collection ring 202 and also form a shield for the blood collection ring 202; furthermore, after the blood collection ring 202 is closed and folded, air circulation can be formed through the ventilation hole 201 to prevent moisture retention.

[0035] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 In order to facilitate the collection of blood by pricking the finger, the blood collection card also includes a blood collection needle assembly 5, which is installed on one side of the collection card 1 for pricking the finger.

[0036] Specifically, the blood collection needle assembly 5 includes a base cylinder 51, a spring 52, a telescopic cylinder 53, a central column 54, and a needle 55. The base cylinder 51 is fixedly connected to the collection card 1. The spring 52 is built into the inner side of the base cylinder 51. One end of the spring 52 is fixedly connected to the base cylinder 51, and the other end is connected to the telescopic cylinder 53. The telescopic cylinder 53 is hollow inside. The central column 54 is fixed inside the base cylinder 51 and coaxially inserted into the inner side of the spring 52 and the telescopic cylinder. The needle 55 is located at the end of the central column 54. The telescopic cylinder 53 has a first position where the spring 52 is compressed and the needle 55 extends out, and a second position where the spring 52 is released and the needle 55 retracts in.

[0037] In this embodiment, a finger presses on the end of the telescopic cylinder 53, pushing it towards the inside of the bottom cylinder 51, compressing the spring 52. The telescopic cylinder 53 slides relative to the bottom cylinder 51, gradually moving until its end is close to the needle 55. The needle 55 extends and pierces the finger, thereby achieving the purpose of pricking the finger to collect blood. When the pressure on the telescopic cylinder 53 is released, the spring 52 rebounds, which retracts the needle 55 into the inside of the telescopic cylinder 53, preventing the needle 55 from being exposed to the outside.

[0038] Furthermore, to enhance the protection of the needle 55 and prevent cross-infection, the blood collection needle assembly 5 also includes a plug 56, which is fixedly connected to the collection card 1 and inserted into the telescopic cylinder 53 in the second position to form a seal. This provides a good sealed environment when the needle 55 is not in use and isolates the needle 55 from the external environment after use, thus preventing cross-infection.

[0039] Furthermore, in order to limit the extension length of the needle 55, a limiting ring 57 is provided on the inner side of the bottom cylinder 51, which abuts against the telescopic cylinder 53 when the telescopic cylinder 53 is in the first position, thereby preventing the needle 55 from extending too far and causing it to penetrate the finger too deeply.

[0040] Furthermore, in order to fit the fingers at the telescopic cylinder 53, the end of the telescopic cylinder 53 away from the bottom cylinder 51 is provided with an upward-facing slope to facilitate finger pressing.

[0041] In one embodiment, please refer to Figure 1 In order to support the bottom space of the collection card 1, the two sides of the collection card 1 are folded downward with support edges 102, thereby supporting the bottom of the collection card 1 and suspending its bottom in the air to provide a good air circulation space.

[0042] Furthermore, an opening 103 is provided on the support along the 102 to allow air circulation.

[0043] In one embodiment, please refer to Figure 2In order to increase the coverage of the desiccant pad 3, the outer periphery of the desiccant pad 3 extends upward to the ventilation hole 201, covering part of the ventilation hole 201, and covering the outer periphery of the blood collection ring 202 for drying.

[0044] Understandably, desiccant pad 3 can be made of silica gel, which can absorb water vapor in the air, but it does not absorb liquids as much as paper towels. Other desiccant materials besides silica gel can also be used, such as calcium chloride and molecular sieves. These materials have strong moisture absorption properties, but their ability to absorb liquids is limited.

[0045] In one embodiment, please refer to Figure 1 The number of the sampling recesses 2 is multiple, and the multiple sampling recesses 2 are distributed in an array for sampling multiple samples.

[0046] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: By pressing the finger against the telescopic cylinder 53, the telescopic cylinder 53 is pushed back and moved into the bottom cylinder 51. After the plug 56 is removed, the entire fingertip can be pressed against the inclined surface of the telescopic cylinder 53. The telescopic cylinder 53 is pushed until it abuts against the limiting ring 57, and the needle 55 extends and pierces the finger. After the finger is pierced, blood is dripped onto the blood collection ring 202 on the collection recess 2. Then the collection cover 4 is closed. At this time, the blood collection card can be air-dried indoors or outdoors. Under the cover of the collection cover 4, the sun will not shine directly on the blood collection ring 202.

[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
