Problems solved by technology

[0002] In the experiment of immunomagnetic reaction, in order to check the positive reaction, it often needs to be implemented with the help of magnetoelectric conversion equipment. The existing experimental equipment often needs to combine the test paper with the magnetic The electric induction device is connected to form a corresponding circuit, and then the detection is carried out. However, in this way, the position of the magnetic induction device and the test paper is relatively fixed, and the electrical signal in the formed circuit changes weakly. Therefore, the test paper with weak immune magnetic response When testing, there are often situations that cannot be detected

Embodiment 1

[0057] like figure 1 and figure 2 As shown, this embodiment discloses an immunomagnetic test paper. The immunomagnetic test paper includes a test paper body 1 and a carrier 2, and the test paper body 1 is fixed to the carrier 2. Wherein: the bottom plate of the test paper body 1 is sequentially pasted with sample pads, magnetic particle-labeled binding pads, chromatographic membranes and water-absorbent pads pre-coated with detection lines and quality control lines; the carrier 2 includes a fixed Connected loading body 21 and loading portion 22, the loading body 21 is provided with an assembly hole 23, the assembly hole 23 is used to cooperate with the rotating shaft, so as to realize the synchronous rotation of the loading body 21 and the rotating shaft The surface of the loading part 22 parallel to the rotation axis is the first side, the test paper body 1 is fixedly connected to the first side, and the detection line and the quality control line are parallel to the rotat...

Embodiment 2

[0063] like Figure 3 to Figure 6 As shown, this embodiment provides an immunomagnetic test paper, which is different from the immunomagnetic test paper embodiment 1 in that: the loading body 21 is oval, the assembly hole is triangular, and the loading part 22 is arranged on The major axis of the ellipse. So that the distance between the test paper body 1 and the magnetoelectric induction device 4 is relatively close, thereby increasing the electrical signal in the magnetoelectric reaction.

[0064] Preferably, a buffer is provided between the test paper body 1 and the loading portion 22 to allow the test paper body 1 to elastically contact the magnetoelectric induction device 4 . Specifically, a groove is provided on the loading portion 22, and the buffer member 9 is arranged in the groove. In this embodiment, the buffer member 9 is a sponge.

[0065] In order to realize the reutilization of the loading body 21, the loading part 22 is detachably connected to the loading bo...

Embodiment 3

[0077] like Figure 7 As shown, this embodiment provides an immunomagnetic test paper, which is different from the immunomagnetic test paper embodiment 1 in that three test paper bodies 1 are provided on one carrier 2 . Through this embodiment, when one carrier 2 rotates, it can simultaneously drive three test paper bodies 1 to rotate.

[0078] In a specific implementation, the thickness of the object body 21 is between 1.5 cm and 15 cm. In the embodiment where the thickness of the loading body 21 is greater than 4 cm, since the width of each test paper body 1 is generally less than 2 cm, each loading body 21 may be provided with more than two test paper bodies 1 . That is to say, a plurality of test paper bodies 1 are provided on one said object body 21 .

[0079] As an alternative embodiment, two test paper bodies 1 may also be provided on one carrier 2 .

[0080] As an alternative embodiment, four, five, six, seven or eight test paper bodies 1 may also be provided on one...
