4 results about "Blood contamination" patented technology

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.

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.
