[0002] A gold label reader is a reader that can be used for qualitative and quantitative detection of colloidal gold immunochromatography reagent plates. This product is widely used in fields such as clinical medical diagnosis, metabolic tests, drug testing, food safety, and scientific research. Currently, reagent plates using the colloidal gold immunochromatography method mainly rely on visual inspection to judge the results, that is, the colors of the test line and the control line on the colloidal gold immunochromatography reagent plate are observed with the naked eye, which can only achieve qualitative judgment, and there is a large human error, and it is impossible to save, print, and trace the test results.

[0003] In the medical device industry, gold label readers are widely used products. The replaceable chamber body is the connection bridge between the gold label reader and the product to be tested. At present, most of the same type of gold label readers on the market are desktop type and have a large volume, which are suitable for laboratory operations. The outdoor application scenarios are easily restricted, and they cannot intelligently identify the types of consumables. Therefore, it is particularly important to develop a portable and small-sized instrument, and it is equipped with several replaceable chamber bodies to adapt to different consumable products, making the application scenarios of the instrument more diverse. Summary of the Invention

[0004] The purpose of the utility model is to provide a replaceable chamber body for a portable gold label reader.

[0005] A replaceable chamber body for a portable gold label reader provided by the utility model includes a housing and a reading window and a magnetic attraction component arranged on the same side of the housing. The reading window is used to expose the detection consumables. During use, the detection consumables are installed on the housing, and the area to be detected is aligned with the reading window. The magnetic attraction component includes multiple magnets; the outer magnetic poles of some or all of the magnets are different, so that there is only a unique relative suction position when the replaceable chamber body is magnetically connected to the gold label reader.

[0006] Preferably, one or more magnets are arranged on both sides of the reading window; the outer magnetic poles of the magnets on both sides of the replaceable chamber body are arranged asymmetrically.

[0007] Preferably, the replaceable cartridge for the portable gold label reader further includes a cartridge type identification component; the cartridge type identification component includes a reference metal contact and a group of identification metal contacts. The group of identification metal contacts includes one or more identification metal contacts. The reference metal contact and the identification metal contacts are both arranged on the outer shell; any number (including 0) of identification metal contacts are electrically connected to the reference metal contact. Different connection sequences between the group of identification metal contacts and the reference metal contact correspond to different types of replaceable cartridges. Therefore, by identifying the connection situation between the group of identification metal contacts and the reference metal contact, the type of the replaceable cartridge can be automatically identified, and then the detection indexes corresponding to the detection consumables in the currently used replaceable cartridge can be reflected.

[0008] Preferably, a gold-plated protective layer is provided on the surfaces of the reference metal contact and the identification metal contacts.

[0009] Preferably, the replaceable cartridge is provided with an inner cavity, and an opening is provided at the top of the inner cavity; a light-shielding cover is rotatably connected to the edge of the opening.

[0010] Preferably, a light-shielding sill is further provided on the outer side surface of the outer shell; the light-shielding sill is in a ring-shaped convex structure and surrounds the outside of the reading window.

[0011] Preferably, the inner cavity of the replaceable cartridge includes a plurality of chambers with different sizes. The chambers are arranged in sequence along the depth direction of the reading window. A communication structure is provided on one side of each chamber facing the reading window; the communication structure is specifically a notch provided on the partition between adjacent chambers for exposing the detection area of the consumable. Different sizes of detection consumables can be inserted into different chambers, so that one replaceable cartridge can match multiple detection consumables.

[0012] Preferably, the replaceable cartridge further includes a heating unit. The heating unit is used to heat the detection consumable.

Detailed implementation manners

[0030] The present utility model will be further described below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] As Figure 1 and Figure 2 shown, a replaceable cartridge for a portable gold label reader includes a light-shielding cover 1, a housing, a fixing hole 4, a cartridge type identification component 5, and a magnetic component 11. The housing includes a rear shell 2 and a front shell 3; a plurality of screw mounting positions 6 are provided on the front shell 3, and the front shell 3 and the rear shell 2 are fixed together by screws mounted on the screw mounting positions 6; one side of the light-shielding cover 1 is hinged to the edge of the top opening of the rear shell 2 through a hinge 7, so that the light-shielding cover 1 can be manually opened and closed, and the replaceable cartridge can be switched between the open state and the closed state;

[0033] As Figure 3 shown, the magnetic component 11 includes two magnets respectively arranged on both sides of the front shell 3. The magnetic poles of the two magnets facing the outside of the front shell 3 are opposite; a reading window 9 and a light-shielding sill 10 are provided on one side surface of the front shell 3; the reading window 9 communicates with the inner cavity of the housing. The reading window 9 is used to expose the detection consumable 8 in the inner cavity. During use, the detection consumable 8 is installed on the housing, and the detection area is aligned with the reading window 9; the light-shielding sill 10 is in a ring-shaped convex structure and is arranged around the outside of the reading window 9.

[0034] The head end of the gold standard reader matching this embodiment is provided with a magnetic structure matching the magnetic component 11. Since the magnetic poles of the two magnets are designed asymmetrically, the replaceable cartridge cannot be misinstalled, thus playing an anti-fooling role and effectively preventing users from installing the cartridge in the reverse direction. When the replaceable cartridge is magnetically installed on the gold standard reader, the light-shielding sill 10 matches the inner side wall of the limit groove section provided on the gold standard reader, fully isolating the light during the detection process from the external natural light and ensuring uniform and stable illumination. The fixing hole 4 matches the fixing post provided on the gold standard reader, enabling the replaceable cartridge to be accurately positioned at the head end of the housing 1.

[0035] In some embodiments, such as Figure 4 and Figure 5 shown, the inner cavity of the outer shell includes three rectangular chambers with different sizes arranged in sequence along the depth direction of the reading window 9; a communication structure is provided on one side of each chamber facing the reading window 9; the communication structure is specifically a notch provided on the partition between adjacent chambers for exposing the consumable detection area. Different chambers can store different types of detection consumables 8, and an anti-fooling device is provided at the position of each detection consumable 8. If the user puts the detection consumable 8 in an inappropriate position, it will not be able to be placed due to incorrect length and width dimensions, reducing the learning cost of the user and also reducing the risk of operation errors;

[0036] Such as Figure 6 shown, the replaceable cartridge has multiple types for realizing the installation of different types of detection consumables. The cartridge type identification component 5 is used to indicate the type of the replaceable cartridge and its corresponding detection mode; the cartridge type identification component 5 includes an identification metal contact group 5-1 and a reference metal contact 5-2. The identification metal contact group 5-1 includes multiple identification metal contacts. The reference metal contact 5-2 and the identification metal contacts are both arranged on the front shell 3 and arranged in sequence along a straight line; any number (including 0) of identification metal contacts are electrically connected to the reference metal contact.

[0037] The head end of the gold standard reader matching this embodiment is provided with metal probes matching the cartridge type identification component 5. After the metal contacts on the replaceable cartridge come into contact with the metal probes of the gold standard reader, a complete circuit is automatically formed. The gold standard reader realizes the type reading of the replaceable cartridge by reading the connection situation between different identification metal contacts and the reference metal contact. Specifically, by allocating different numbers of metal contacts, multiple signal circuit combinations are formed, corresponding to different types of replaceable cartridges. Therefore, by identifying the connection situation between the identification metal contact group and the reference metal contact, the type of the replaceable cartridge can be automatically identified, and then the detection index corresponding to the detection consumable 8 in the currently used replaceable cartridge can be reflected.

[0038] Figure 7The white dots indicate that the metal contacts are undefined (i.e., it is marked that the metal contacts are not connected to the reference metal contacts). The metal contacts in different columns represent the cartridge type identification components 5 on different replaceable cartridges, corresponding to different detection modes. If all metal contacts are undefined, it means that intelligent switching of detection types is not supported, and the user needs to manually select the detection type in the gold standard reader. For example:

[0039] In the first column, the white dots indicate that all metal contacts are undefined, indicating that the low - version does not support intelligent identification, and the user needs to check the detection type manually in the software interface; the detectable mode 1 can be used;

[0040] In the second column, the black dots indicate that all metal contacts are defined, and the detectable mode 2 can be used;

[0041] The third column indicates the detectable mode 3;

[0042] And so on.

[0043] The surface of the metal contacts is provided with a gold - plated antioxidant protection layer, which ensures that the surface of the metal contacts will not rust, improves the reliability of the connection, and also extends the service life.

[0044] In some embodiments, the cartridge type identification component 5 further includes a power supply control metal contact; the head end of the gold standard reader matching this embodiment is provided with a metal probe matching the power supply control metal contact; thus, the electronic device in the replaceable cartridge can be powered through the power supply control metal contact.

[0045] The working principle of the present utility model is as follows: Put the detection consumable 8 into the chamber of the replaceable cartridge and close the light - shielding cover 1; as Figure 8 shown, install the replaceable cartridge onto the gold standard reader through the fixing holes 4, the light - shielding sill 10 and the magnetic attraction component 11 for measurement. By using different distributions of the metal contacts on the replaceable cartridge, the gold standard reader can switch the inspection mode to detect the detection consumable 8. If there are multiple detection consumables 8 in the chamber of the replaceable cartridge, the gold standard reader only detects the detection consumable 8 closest to the reading window 9.
