This invention belongs to the field of biodetection technology and discloses specific PCR primers and identification methods for the subspecies of Mycobacterium abscessus. The differentiation effect of this invention on the three subspecies of Mycobacterium abscessus is equivalent to whole-genome sequencing, while the established detection method does not rely on sequencing, is rapid and low-cost, and has low requirements for equipment and personnel, making it applicable to laboratories at all levels. The amplification method has low template requirements; it is applicable to raw samples such as sputum, bronchoalveolar lavage fluid, pleural and peritoneal fluid, cultures, and extracted nucleic acids, and is not culture-dependent. Identification of the three subspecies is based on product length rather than amplification negative / positive (presence or absence of bands), avoiding false negative results. The product length differences are significant (above 1000 bp), making results easy to interpret, reducing the impact of electrophoresis errors on results, and improving the accuracy and stability of detection. The detection reagents based on this invention can be widely used in clinical precision testing and epidemiological monitoring, among other related fields.

This invention relates to a sensor (e.g., an optical sensor) that can be implanted in a living animal (e.g., a human) and used to determine analytes (e.g., glucose or oxygen) in intracellular media (e.g., interstitial fluid, blood, or peritoneal fluid). The sensor may include a sensor substrate, electrodes or a housing, an analyte indicator covering at least a portion of the sensor, and one or more probes for identifying degradation substances in the sensor environment.

Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,”“pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

This utility model relates to the field of puncture needle technology, specifically a puncture needle with a guiding function. The utility model includes an injection tube and a puncture needle head, which are fixed together. A piston is provided on the inner wall of the injection tube, and an operating rod is fixedly connected to the right end of the piston. A guiding component is provided on the left end of the injection tube, and an auxiliary collection component is provided at the lower end of the injection tube. By using the auxiliary collection component, when aspirating peritoneal fluid from a patient, a rubber tube is inserted into a connecting tube, the puncture needle head is inserted into the patient's abdomen, and the operating rod is dragged to move the piston, aspirating the fluid. Once the injection tube can aspirate the fluid, the cap is opened, and the collection bag is pressed, causing the air inside the collection bag to escape from the operating tube, thus creating a negative pressure inside the collection bag. The fluid in the injection tube is then drawn into the collection bag through the rubber tube, potentially achieving the goal of completely aspirating the patient's peritoneal fluid in one procedure.

The application discloses a drug-loadable suspension microbubble, a preparation method and application thereof. The microbubble with a shell and an internal gas cavity is constructed through emulsification, cross-linking and drying, and the particle size of the microbubble and the size of the gas cavity are adjusted by controlling the concentration of shell-forming material, stirring speed and cross-linking agent concentration in the preparation process, so that the density of the microbubble is controlled. The density of the obtained microbubble is between 0.990 and 1.010 g / cm 3 The microbubble can be stably and uniformly suspended in physiological saline and peritoneal fluid. That is, the application creatively takes the controllable density as a core design principle, develops a microbubble which can be suspended and uniformly distributed in peritoneal fluid, and ingeniously solves the problem of uneven distribution of drug carriers in the peritoneal cavity by loading drugs, and meanwhile integrates the ultrasonic visualization and drug release functions, so as to provide a new solution for precise diagnosis and treatment of peritoneal cancer and other body cavity diseases.
