Description

Technical Field

[0001] The utility model relates to the technical field of detection auxiliary devices, in particular to a biological detection card and a matching structure thereof. Background Art

[0002] In the hospital disinfection supply center, surgical instruments need to be cleaned by medical cleaning machines. At present, there is no precise cleaning effect judgment system for medical cleaning machines. In the field of food safety, there are ATP fluorescence testers that detect bacterial content alone and protein residue testers that detect protein content alone. However, the quantitative detection technology of bacteria and protein has not been applied to the field of medical device cleaning effect detection. There is currently no systematic cleaning machine cleaning effect detection method in the field of medical device cleaning effect detection. For example, the Chinese patent, the authorization announcement number is CN215297561U, which discloses a sampling device for semiconductor detection equipment, which includes a carrier, a limit assembly and a push assembly; the carrier: the upper surface is provided with a groove, the bottom surface of the groove is provided with a vortex partition plate, and the bottom surface of the groove is provided with an avoidance groove; the limit assembly is arranged at the right end of the carrier, and the limit assembly is installed in conjunction with the V-shaped spring symmetrically arranged at the left end of the upper surface of the carrier. However, this scheme can only perform a single concentration test at a time, which is not efficient enough, resulting in low detection efficiency; there is no disposable tank body that cooperates with the equipment for multiple tests, which is easy to cause cross infection and affect the detection effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a biological detection card and a matching structure thereof.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A biological detection card comprises a card body, a carrier plate arranged on the card body, and a bacterial liquid layer coated on the carrier plate, wherein:

[0006] The card body, which is a sheet of metal or plastic;

[0007] The carrier plate is rectangular and located in the center of the card body, and has several groups of partitions symmetrically arranged along the center line of the long side of the card body; each group of partitions is a detection area;

[0008] The bacterial liquid layer is coated on the central area of ​​each group of partitions, and the bacterial liquid adhesion and concentration in the bacterial liquid layer are different.

[0009] This technical solution can detect the cleaning effect of the cleaning machine at the same time by improving the biological detection card, thereby improving the detection efficiency. First of all, the card body needs to be reused, so it is made of corrosion-resistant metal material or lighter plastic material; the carrier plate is the detection area, which can be set by additionally sticking it on the card body and then torn off after use; it can also be a plate processed integrally with the card body; lines are processed on the carrier plate to distinguish different partitions; each group of partitions is a detection area, and multiple samples are tested at the same time to improve the detection efficiency. The difference in adhesion and concentration of the bacterial liquid in the bacterial liquid layer is to meet different detection needs. For example, in some application scenarios, spores may have lower adhesion, while in other scenarios they may have higher adhesion; by testing the spore liquid in these two situations, the performance of the biological detection card in different environments can be evaluated.

[0010] In addition, the above-mentioned biological detection card and its matching structure according to the utility model may also have the following additional technical features:

[0011] According to an embodiment of the present invention, the bacterial liquid layers on the same side of the center line of the long side of the card body have the same adhesion, and the concentrations are arranged one by one from low to high.

[0012] In this technical solution, on the same side, since the concentrations are arranged one by one from low to high, the growth or reaction of microorganisms at different concentrations can be observed. On different sides, the concentrations are the same but the adhesion is different, so the effect of adhesion on the growth or reaction of microorganisms can be observed. In order to improve the efficiency of detection, multiple biological detection cards can be put into the same cleaning machine to comprehensively judge the cleaning effect and improve the detection efficiency.

[0013] According to an embodiment of the utility model, the edge of the card body is a blank area, which is used to hold the blank area and put it into a cleaning machine for cleaning, and then put it into a detector for residual concentration detection.

[0014] In this technical solution, the blank area is the hand-held area, which can avoid affecting the coated bacterial liquid layer when holding it, and reduce the influence of the operator on the test results. The biological detection card has two functions in total. One function is to be placed in a cleaning machine for cleaning, thereby diluting the concentration of the bacterial liquid on the bacterial liquid layer; the other function is to be placed in a detector for testing, so as to determine whether the cleaning of the cleaning machine meets the standards.

[0015] According to an embodiment of the utility model, the bacterial liquid attached to the bacterial liquid layer is a spore bacterial liquid. After the spore bacterial liquid is cleaned, the residual bacteria or spores react with adenosine triphosphate to emit fluorescence.

[0016] In this technical solution, the fluorescence detection method usually has a high sensitivity, and a small amount of bacteria or spores remaining on the biological detection card can also be accurately detected. The spore liquid is the detection object, and the fluorescence is emitted after the reaction, and the fluorescence is used to determine whether the residual concentration exceeds the threshold.

[0017] The technical solution adopted by the utility model is as follows:

[0018] A matching structure of a biological detection card, using the above biological detection card, includes a disposable lysis tank, including a tank body, a groove arranged on the tank body, and a partition arranged between the tank bodies, wherein:

[0019] The tank body is in the shape of a rectangular parallelepiped and is used to hold the biological detection card and put it into the detector for residual concentration detection;

[0020] A groove is transversely arranged at the bottom of the tank body, has the same size as the biological detection card, and is used to accommodate the biological detection card;

[0021] The partition is vertically arranged between the slots and is spaced into a plurality of detection holes, each detection hole corresponding to a partition of the biological detection card one by one.

[0022] This technical solution can detect the partitions on the biological detection card at the same time by specially setting up a disposable lysis tank that matches the biological detection card; the disposable lysis tank is provided with a number of corresponding detection holes, and synchronous detection helps to reduce operational errors, improve detection accuracy, and reduce operating steps, thereby improving the detection efficiency of the biological detection card. Among them, the shape of the tank body meets the needs of convenient insertion and removal of the biological detection card, and also takes into account the compatibility with the detector; the size of the groove is the same as that of the biological detection card, which is used to accurately place it in the correct position in the lysis tank; the partition divides the tank body into a number of detection holes, reducing cross contamination between different partitions and ensuring the accuracy and reliability of the results.

[0023] In addition, the above-mentioned biological detection card and its matching structure according to the utility model may also have the following additional technical features:

[0024] According to an embodiment of the utility model, the disposable cracking tank is a plastic structure that is formed in one go.

[0025] In this technical solution, the disposable lysis tank is not allowed to carry contaminants, so it is necessary to use products made of disposable materials, which are safer and more hygienic, and are especially suitable for use in medical or laboratory environments.

[0026] According to an embodiment of the present invention, the partition plate extends from the top of the slot body to the groove at the bottom. After the biological detection card is inserted into the slot body, the partition plate and the biological detection card form an independent detection hole.

[0027] In this technical solution, the partition needs to reduce the gap between the partition and the biological detection card in the horizontal direction to avoid mutual influence; the partition needs to maintain independent detection of each detection hole in the vertical direction to provide a closed environment for fluorescence detection.

[0028] According to an embodiment of the utility model, the detection hole is used to place a tube filled with diluted lysis solution and a sensor for detecting fluorescence.

[0029] In the present technical solution, the detection hole is a detection channel of a disposable lysis tank, which is used for both the addition channel of adenosine triphosphate (ATP), where adenosine triphosphate (ATP) is used as an indicator or marker, and the collection channel of a fluorescent sensor. The fluorescent signal generated by the fluorescent sensor detection reaction can be used to indirectly measure or analyze the residual bacteria or spores.

[0030] Compared with the prior art, the utility model has the following beneficial effects:

[0031] (1) By improving the biological detection card, the cleaning effect of the cleaning machine can be tested at the same time, thereby improving the detection efficiency.

[0032] (2) By specially setting up a disposable lysis tank to match the biological detection card, the partitions on the biological detection card can be detected at the same time; the disposable lysis tank is provided with a number of corresponding detection holes, and synchronous detection helps to reduce operational errors, improve detection accuracy, reduce operating steps, and thus improve the detection efficiency of the biological detection card.

The biological detection card has two functions, one is to be placed in a cleaning machine for cleaning, thereby diluting the concentration of the bacterial liquid on the bacterial liquid layer 3; the other is to be placed in a detector for testing, so as to determine whether the cleaning of the cleaning machine meets the standards.
