3 results about "Throat swab sample" patented technology

The disclosure provides a throat swab loaded with a reticular MOF black phosphorus nanocomposite for SERS detection and a preparation method thereof, the throat swab is composed of a throat swab sampling cotton swab and a reticular MOF coated sheet-shaped black phosphorus, the reticular MOF coated sheet-shaped black phosphorus is coated on the head of the throat swab sampling cotton swab; the foam hole density of the head of the throat swab sampling cotton swab is 300 ppi; the reticular MOF has a pore size of 200-300 nanometers and a nanoscale gap structure on the surface; the sheet-shaped black scale has a diameter of 1000-5000 nanometers; the black phosphorus has good biocompatibility with the reticular MOF, the throat swab sampling cotton swab is used as a bearing matrix, and the throat swab is simple to make and low in cost, and the open reticular foam structure of the throat swab is helpful for complete release of a sample into a culture solution, and a large number of protruding structures on the surface of the throat swab can further enhance the Raman signal of an adsorbed molecule.

The application belongs to the technical field of biological detection, and particularly relates to an isothermal amplification detection reagent and kit for detecting varicella-zoster virus (VZV). The application designs a specific primer pair with a target of a conservative region of an ORF62 of a VZV genome, performs RPA reaction, combines a modified detection probe, and uses lateral flow chromatography test paper to realize a detection sensitivity of not higher than 1 copy / µL for a crude extract of a vesicle fluid or throat swab sample, realize rapid and high-sensitivity detection, and has good popularization and application value.

The application relates to a swab unpacking device and a throat swab sampling robot. The swab unpacking device is used for taking out swabs in a swab connected package, the swab connected package comprises a plurality of sequentially connected packaging bags, and the swab unpacking device comprises a rack, a cutting station arranged on the rack, a cutting mechanism configured to cut the packaging bag located at the cutting station, a conveying mechanism configured to convey the swab connected package so that the packaging bag in the swab connected package moves to the cutting station along a first direction, and an ejection mechanism comprising a first driving member and an ejecting member connected with the driving member, wherein the first driving member is configured to drive the ejecting member to move along a second direction so as to eject the swab in the packaging bag at the cutting station and cut by the ejecting member. The swab unpacking device in the application can replace manual work to complete the swab unpacking work, and can release medical staff from the heavy and tedious unpacking work, thereby reducing the work burden of the medical staff.
