The invention belongs to the technical field of tissue engineering, in particular to a decellularization method. The biological material to be treated is placed in a container, and then the cell eluent flows through the container until the decellularization of the biological material is completed. The decellularization method decellularizes the biological material, so that the biological material can be completely processed, the effect of decellularization is greatly improved, and the internal structure and mechanical properties of the biological material are well preserved. Moreover, the method of the present invention can automatically discard waste liquid and automatically clean, greatly reducing the operation steps and water consumption in the process of cell elution and cleaning.

The invention discloses a search and rescue robot, comprising a basal body, a middle framework, motors, PVC (polyvinylchloride) tubes, a camera and a light source module. The basal body is a circular cylinder, both two ends of which are of semi-spherical elastic soft structures. The middle framework is of a transverse I-shaped structure. The basal body is sleeved on the middle framework. A motor groove and four PVC tube grooves are arranged on the middle framework. A plurality of motors are fixed on the basal body and form a ring by being connected from end to end through a rope. The ring passes through the motor groove of the middle framework. The tail ends of the motors are provided with light sensitive resistors. A plurality of PVC tubes are fixed on the basal body. Each four PVC tubesin a vertical plane of a motor shaft of one corresponding motor are connected with the corresponding motor through a rope and correspond to the four PVC tube grooves of the middle framework respectively. The camera and the light source module are fixed at the front and rear ends of the middle framework respectively. By means of the structure of the invention, the search and rescue robot can advance in a clearance, which is smaller than self size, so as to search and rescue trapped persons under ruins.

The invention discloses an optical cable cross-connecting box for capacity expansion transformation. The box comprises a top frame with a cuboid structure, vertical rods, a motor I and a line concentration frame. The top frame is horizontally arranged at the top of the cross-connecting box, the vertical rods are vertically arranged below four corners of the top frame, and a bottom plate with the cuboid structure is vertically arranged at the bottoms of the vertical rods. The beneficial effects of the box are that a motor II drives a gear II to roll in a rolling groove I in cooperation with a rack I so as to adjust a height of a transverse connecting rod and the height of the line concentration frame; a motor III on the line concentration frame drives a gear III to roll in a rolling grooveII so that the line concentration frame is driven to move back and forth; and multiple branching assemblies can be arranged on a sleeve shaft in a sleeving mode through rubber leather sleeves in sliding holes to adjust the positions so that a distance between the multiple branching assemblies is changed. The cross-connecting box can be ensured to be used for adjusting the branching assemblies containing optical cables in multiple directions, and positions where the branching assemblies are connected with the optical cables in a centralized mode are more accurate and appropriate.

The invention discloses an optical fiber junction box capable of controlling incoming lines, comprising a bottom plate. One end of the bottom plate is fixedly connected with a fixing cover. Pressing blocks are arranged on the outer side of the fixing cover. Springs are connected to the inner side of the pressing blocks. The ends of the springs are connected with fixing blocks. Connecting rods areconnected to the outer sides of the springs. Hook blocks are connected to the tail ends of the connecting rods. According to the optical fiber junction box capable of controlling incoming lines, the sliding connection structure of the optical fiber junction box can be achieved by arranging sliding grooves and sliding blocks, so that the optical fiber junction box is more convenient to use comparedwith conventional optical fiber junction boxes, and maintenance personnel do not need to carry a large number of tools to open and dismount when checking and maintaining, thus the opening difficultyof maintenance personnel in maintenance is reduced, the opening and closing time is reduced; the connecting structure of a fixing cover and a sliding cover is achieved through arranging the hook blocks and the blocking blocks; and the purpose of opening and closing of the fixing cover and the sliding cover is achieved by pressing the pressing blocks, so that the opening structure of the optical fiber junction box is simple, the sealing effect is good, the dismounting is convenient, and the junction box is suitable for household use.

The invention belongs to the technical field of tissue engineering, and in particular relates to a decellularization device. The decellularization device comprises a first pipeline, a first container, a second pipeline, a second container and a third pipeline, and a third container connected to the third pipeline in sequence; one end of the first pipeline is connected to the second pipeline. The first opening of a container; one end of the second pipeline is connected to the second opening of the first container; the other end of the second pipeline and one end of the third pipeline are respectively connected to two ends of the second container; the second The container is used to place biological material, and biological material cannot enter into the second pipeline and the third pipeline. The device is used to decellularize the biological material, so that the biological material can be completely processed, and the effect of decellularization is greatly improved. And the waste liquid can be automatically discarded and cleaned automatically, which greatly reduces the operation steps and water consumption in the process of cell elution and cleaning.
