According to the scheme, the functions of centrifugation, separation and blood return are integrated in one tank body, and the whole process is not contacted with air, so that sealed centrifugation, sealed separation and sealed blood return are realized, the blood can be prevented from being polluted, and the safety in an autologous platelet-rich plasma process is ensured.

This invention relates to a quick-change device and a surgical robot. The quick-change device includes: a first mounting assembly including a first mounting base mounted on the end of a robotic arm; a second mounting assembly including a second mounting base disposed on the end of a surgical instrument, the second mounting base being detachably mounted on the first mounting base; and a wireless transmission assembly including a transmitting component and a receiving component. The transmitting component is disposed on the first mounting base and electrically connected to the controller of the robotic arm, and the receiving component is disposed on the second mounting base. After the first and second mounting bases are connected, the transmitting component and the receiving component wirelessly power and transmit signals. This enables the rapid installation, removal, and replacement of surgical instruments. Simultaneously, the use of a wireless transmission component for non-contact transmission of power, control, and other signals ensures the entire quick-change device is sealed, reducing blood contamination.

The utility model provides a glucometer, which belongs to the technical field of glucometers and comprises an upper shell, a penetrating opening is arranged on the surface of the upper shell, a connecting component is arranged on the inner wall of the upper shell and is used for connecting and limiting the upper shell and a lower shell, a pushing component is arranged below the upper shell and is used for pushing test paper, and the test paper is arranged in the penetrating opening. The pushing assembly comprises a lower shell, two sets of male buckles are symmetrically arranged on the edge of the lower shell, two sets of limiting columns are symmetrically arranged on the inner wall of the lower shell, multiple sets of screw cylinders are symmetrically arranged on the inner wall of the lower shell, the limiting columns are sleeved with a circuit board, and conductive silica gel is welded to the top of the circuit board. A display screen is arranged on the top of the conductive silica gel, and a battery body is arranged in the bottom of the lower shell. Through the arrangement of the pushing assembly, a user can conveniently push test paper out of equipment without pulling out the test paper with effort, fingers or instruments are prevented from being polluted by blood, and the risk of cross infection is reduced.

The invention discloses a portable deer blood sterile collection and preservation device which comprises a portable box structure, the portable box structure comprises a box body, and the top surface of the interior of the box body is sleeved with an upper-layer placement groove; according to the collection and storage structure, the vacuum blood collection bin and the vacuum blood storage bin are integrated together and separated through the partition assembly, blood enters the vacuum blood collection bin after blood collection, and during storage, the short tube is opened through the partition assembly, so that the blood is transferred into the vacuum blood storage bin, and the blood is in a closed state during transfer; a self-locking female connector assembly is arranged in the collection and storage structure, a self-locking male connector assembly is arranged in the blood taking needle structure, blood taking is carried out through connection of two connectors, the mode that the tail end of a needle tube is inserted into a traditional vacuum blood taking device is abandoned, and therefore when the collection and storage structure is continuously replaced for blood taking, after the collection and storage structure is pulled out, blood taking can be carried out conveniently. The self-locking male connector assembly is immediately closed, so that the condition of blood pollution in the process is avoided, and the sterile blood collection is realized by the device.

This application discloses a blood collection system and method based on disposable blood collection needles. The blood collection system includes: an image acquisition unit for acquiring real-time images of the blood collection operation area; an AI processing unit connected to the image acquisition unit for receiving the real-time images and using deep learning algorithms to identify and monitor the blood collection actions and sequence in the real-time images to determine the integrity of the blood collection process and the compliance of the blood collection operation, and generating detection results; and a human-computer interaction unit connected to the AI ​​processing unit for receiving the detection results and providing prompts for each operation step of the blood collection process based on the detection results. According to this application, it standardizes the blood collection operation process and reduces blood contamination.
