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.

Abstract

The invention relates to the technical field of in vitro detection, and particularly relate to trace sample test paper which comprises a test paper body and a sample collector. A hemocyte filter membrane is arranged on a sample pad, a stabilizing solution storage tank is arranged on the hemocyte filter membrane, and the sample collector comprises a negative pressure piece and an anti-coagulation sample pipe. According to the trace sample test paper, the anti-coagulation sample pipe is arranged in the sample collector, and thus the blood coagulation of a blood sample can be remarkably reduced, the loss of blood plasma is reduced, and thus the collecting quantity of a blood sample can be reduced. the stabilizing solution storage tank is arranged on the sample pad, the blood sample is dropwise added in the stabilizing solution storage tank so that the blood sample can be stabilized and diluted, thus the coagulation is reduced, and thus blood plasma in the blood sample is fully utilized, blood in fingertip can be used as a detection sample of rapid detection test paper, and the sample collecting quantity can be less than 1 mu L. By arranging a negative pressure bin, a liquid in the storage tank can completely and rapidly flow in the sample pad, and thus the utilization rate of the sample is increased.

Description

technical field [0001] The invention relates to the technical field of in vitro detection, in particular to a micro sample detection test paper. Background technique [0002] With the progress of society and the improvement of living standards, people pay more and more attention to their own health, and pay more and more attention to the early diagnosis and screening of diseases. Therefore, more accurate and convenient diagnostic testing methods are needed to meet this requirement. Diagnostic test strips, as a detection method widely accepted by testing personnel, medical workers and users, are characterized by fast, convenient and low price, and are more and more valued by everyone. [0003] Rapid diagnostic test paper is a solid reagent developed in the past two decades. It has the advantages of simplicity, speed, accuracy and low price. The simplest is to use a piece of test paper, soak the specimen, and compare it with the standard color plate to get the test result. ...
