The invention relates to the technical field of biological sample detection, in particular to a biological sample reaction box. A reagent storage part and a push rod capable of moving relative to the reagent storage part are packaged in the reaction box; the reagent storage part is provided with at least one reagent accommodating cavity, and the reagent accommodating cavity is sealed by a sealing element; the push rod is connected with the sealing element, and the push rod is used for being matched with external equipment mutually so that the sealing element is separated from the reagent storage part. The reagent storage part and the push rod are both packaged inside the biological sample reaction box; during reaction, the biological sample reaction box is matched with a detection box only, the biological sample reaction box is inserted in the external equipment through one-step operation, and quick release of reagents in the reagent storage part can be realized.

The invention provides a human urine automatic detection system. The system comprises a control module, a urine collection module, a detection module, an output module, and a cleaning module. The control module controls operation of a whole system and includes an instruction input unit. The urine collection module is used to collect urine to be detected. The detection module includes a detection probe seat and is used for detecting the collected urine to be detected, and obtaining a corresponding detection report according to a detection result. The output module is used to output the detection report, and the cleaning module is used to clean a system component which the urine to be detected flows through or where the urine to be detected is stored in the system. By using the human urine automatic detection system, automatic collection of human urine and subsequent automatic detection can be integrated into one body, a whole urine inspection process is effectively simplified, an operation process is humanized and a user experience is good.

The disposable polymer-structured filtering kit includes a disposable, polymer-structured filtering funnel with a stem having a distal tip. A flow discharge end is formed at the distal tip. Preferably, a polymer fritted filter disc is positioned in the funnel, providing filtering for liquids passing therethrough. The kit preferably also includes a glass vacuum take-off adapter having a port for connecting to a vacuum source for providing negative pressure. The adapter securely and snuggly receives the funnel and maintains position of the distal tip thereof with the flow discharge end below the port, thus preventing contaminants from entering the adapter. A reusable, glass round bottle flask or a disposable vial receives the adapter and the stem of the funnel. The funnel and fritted disc are formed from disposable materials, thus removing the necessity of cleaning them following use. The adapter is reusable, since no contaminants come in contact therewith during filtering.

The invention discloses a lossless transfer device for droplets. The device comprises a power generation part and a clamping part, the power generation part comprises a movable friction material and at least two fixed friction materials, the clamping part comprises a supporting mechanism, a left dielectric wetting clamping plate and a right dielectric wetting clamping plate, the left dielectric wetting clamping plate and the right dielectric wetting clamping plate are installed on the supporting mechanism, the movable friction materials are connected with the left dielectric wetting clamping plate, and the at least two fixed friction materials are connected with the right dielectric wetting clamping plate. The invention also discloses a lossless droplet transfer method and a droplet micro-reaction method. The device is more portable; by using a crank connecting rod mechanism, the left dielectric wetting clamping plate moves in the horizontal direction, and the device can adapt to liquid drops of different sizes conveniently; the accuracy of horizontal movement of the left clamping plate is ensured; a bolt and a spring are arranged, so that the left dielectric wetting clamping platecan horizontally move leftwards or rightwards conveniently; and the movement of droplets can be controlled, and the driving and fusion of the droplets are realized.
