  • Patent number: 11511036
    Abstract: The infusion pump for stem cells includes a liquor storage device and an infusion pipe. The inner wall of the liquor storage sac of the liquor storage device and inner walls of the infusion pipe are provided with an anionic protective film to prevent stem cells from adhering to the infusion pump by mutual repulsion between anions. The infusion method includes checking an infusion pump for integrity, losing a liquor stop clamp, injecting a mixed liquor of stem cells and medicine, covering a protective cap, opening the liquor stop clamp, closing the liquor stop clamp for use, connecting an external cone joint with a venous cannula, and then opening the liquor stop clamp. The method also includes steadily placing the liquor storage sac on a horizontal plane using an auxiliary placing device, and after infusion ends, closing the liquor stop clamp, and disconnecting the external cone joint.

  • Publication number: 20190175830
    Abstract: The special infusion pump for stem cells includes a liquor storage device and an infusion pipe. The inner wall of the liquor storage sac and the infusion pipe is provided with a layer of anionic protective film, to prevent stem cells in physic liquor from adhering to the inner wall of the liquor storage sac and the infusion pipe using mutual repulsion between anions. The infusion method includes: checking an infusion pump for integrity; closing a liquor stop clamp, injecting a mixed liquor of stem cells and medicine; covering a protective cap, opening the liquor stop clamp, closing the liquor stop clamp for use; connecting an external cone joint with a venous cannula, and then opening the liquor stop clamp; steadily placing the liquor storage sac on a horizontal plane using an auxiliary placing device; and after infusion ends, closing the liquor stop clamp, and disconnecting the external cone joint.

  • Patent number: 9516482
    Abstract: Provided are a call request processing method and device. The method includes: obtaining state information of a second communication identification card located in a same terminal with a first communication identification card; processing a call request according to the state information, wherein the call request is used for calling the first communication identification card. According to the solution, the technical problem that because only one radio frequency transceiving chip is set in a dual-mode dual-card phone, if one card is in a communication state, a call to another card is easily lost is solved, thereby reducing call loss.
