DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a sample collection device for genetic diagnosis of inherited metabolic diseases in newborns comprises a blood sample collection card 1, on which a blood sample protection component 2 is installed, the blood sample protection component 2 is composed of a connecting cardboard 7, a covering cardboard 8 and a protective film 9, there are two covering cardboards 8 and they are fixedly installed at both ends of the connecting cardboards 7, there are two protective films 9 and they are fixedly installed at one end of the two connecting cardboards 7, a protection component limiting structure 3 is slidably installed on the blood sample collection card 1, the protection component limiting structure 3 is composed of a connecting base rod 10, a limiting connecting plate 11 and a limiting baffle 12, the limiting connecting plate 11 is fixedly installed at both ends of the connecting base rod 10, the limiting baffle 12 2 are respectively fixedly mounted at one end of the two limiting connecting plates 11. When genetic diagnosis of genetic metabolic diseases is performed on newborns, the blood sample collection card 1 can be used to collect blood from the newborns. The method is to first use a needle to puncture the heel of the newborn, and then collect the blood on the blood sample collection card 1, and then use the blood sample protection component 2 to protect the collected blood sample. At this time, the connecting paperboard 7 on the blood sample protection component 2 can be bent so that the two protective films 9 on the two covering paperboards 8 are respectively attached to the two sides of the blood sample collection card 1, and then the protection component limiting structure 3 is slid on the blood sample collection card 1, so that the blood sample protection component 2 can be fixed using the protection component limiting structure 3.

[0024] Specifically, the blood sample collection card 1 is provided with an information filling area 4 and a blood collection area 5, an installation groove 6 is opened on the blood sample collection card 1 and between the information filling area 4 and the blood collection area 5, and an installation guide groove 13 is opened at the edge of the blood sample collection card 1 and near the blood collection area 5. The installation groove 6 and the installation guide groove 13 both penetrate the blood sample collection card 1. When using the blood sample collection card 1 to collect blood samples, the blood sample can be dropped into the blood collection area 5 on the blood sample collection card 1, so that the blood is immersed in the blood collection area 5.

[0025] Finally, by setting a blood sample protection component 2 on the blood sample collection card 1, the blood sample protection component 2 can protect the blood sample collected on the blood sample collection card 1, thereby preventing the blood spot on the blood sample collection card 1 from contacting with foreign objects during the transfer, transportation and storage of the blood sample collection card 1, thereby preventing the blood spot from being contaminated, and ultimately ensuring the accuracy of the test result. By setting a protection component limiting structure 3, the blood sample protection component 2 can be conveniently fixed, and the blood sample protection component 2 can also be conveniently released, thereby making the blood sample collection card 1 easier to use.

[0026] Furthermore, the connecting cardboard 7 on the blood sample protection component 2 passes through the installation groove 6 opened on the blood sample collection card 1, and the two covering cardboards 8 are respectively located on both sides of the blood sample collection card 1, and the protective film 9 is close to the blood collection area 5 on the blood sample collection card 1. When the blood sample protection component 2 is used to protect the blood sample, the connecting cardboard 7 can be bent, so that the two protective films 9 are respectively attached to the two sides of the blood collection area 5. Conversely, when the blood collection area 5 needs to be used, the connecting cardboard 7 can be bent in the opposite direction, so that the protective film 9 is out of contact with the blood sample collection card 1, thereby exposing the blood collection area 5.

[0027] Furthermore, the connecting base rod 10 on the protection component limiting structure 3 is slidably installed in the installation guide groove 13 opened on the blood sample collection card 1, and the two limiting connecting plates 11 on the protection component limiting structure 3 are respectively located on both sides of the blood sample collection card 1. When the protection component limiting structure 3 is used to fix the blood sample protection component 2, the protection component limiting structure 3 can be pulled, so that the two limiting baffles 12 are finally blocked on the outside of the two covering cardboards 8 respectively, and the blood sample protection component 2 is fixed at this time. Conversely, when the fixation of the blood sample protection component 2 needs to be released, the protection component limiting structure 3 can be pushed in the opposite direction, so that the two limiting baffles 12 are finally moved away from the outside of the two covering cardboards 8 respectively, and the fixation of the blood sample protection component 2 is released at this time; when the protection component limiting structure 3 moves on the blood sample collection card 1, the connecting cardboard 7 will slide in the installation guide groove 13.
