Embodiment 1
[0029] refer to Figure 1-9 , a rapid detection test strip for diagnosing heart disease provided in this embodiment includes a test strip body 20 , a sample collector 10 and a plastic support frame 30 . Wherein, the test paper body 10 is composed of a bottom plate 25, a sample pad 21, a binding pad 22, a reaction membrane 23, an absorption pad 24, a blood cell filter membrane 26, a stable liquid storage tank 28, and a negative pressure chamber 27; Part 11 and anticoagulant sample tube 12 constitute.
[0030] like Figure 1-2 As shown, the negative pressure member 11 in the sample collector 10 is an elastic ball, and the anticoagulant sample tube 12 is a siphon tube filled with anticoagulant 14, and one end of the siphon tube is sealed and inserted into the elastic ball, so that the siphon tube and the elastic ball The other end of the siphon tube is sealed with a sealing film 13 so that the anticoagulant 14 is preserved in the siphon tube. In this embodiment, the anticoagul...
Embodiment 2
[0037] The rapid detection test paper provided in this embodiment for detecting heart disease is basically the same in structure as the rapid detection test paper described in Example 1, except that the pressure in the negative pressure chamber is set to 10Pa. The prepared rapid detection test paper is marked as TP2.
Embodiment 3
[0039] The rapid detection test paper provided in this embodiment for detecting heart disease is basically the same in structure as the rapid detection test paper described in Example 1, except that the pressure in the negative pressure chamber is set to 20Pa. The prepared rapid detection test paper is marked as TP3.
