The utility model discloses a centrifugal machine and a workstation for extracting and enriching trace microorganisms from a complex matrix, the centrifugal machine comprises a main body frame, a partition plate is arranged in the middle of the main body frame, and the centrifugal machine is divided into a centrifugal chamber and an accessory chamber by the partition plate; the rotor assembly is arranged above the partition plate, is positioned in the centrifugal chamber and is used for placing a sample; a refrigeration assembly is arranged on the outer wall of the centrifugal chamber and used for cooling or refrigerating the centrifugal chamber; the positioning assembly is arranged below the partition plate and located in the accessory chamber. When the centrifugal machine is used for separating and enriching infectious samples, most of impurities such as human cells, proteins, saccharides, salts and the like in uncultured or cultured clinical samples such as blood, cerebrospinal fluid, urine, hydrothorax and ascites and the like can be effectively removed, and relatively pure living pathogens are obtained.

The utility model relates to a device for preventing hydrothorax and ascites from leaking, which effectively solves the problems that patients feel uncomfortable and the workload of medical staff is increased due to repeated seepage of puncture holes. Comprising an annular non-woven fabric, an anti-seepage ring is fixed to the inner side of the non-woven fabric, a circular water-absorbing dressing bag with a downward opening is fixed to the upper end of the anti-seepage ring, a polyester foam sleeve with a downward opening is fixed to the inner side of the water-absorbing dressing bag, the polyester foam sleeve is filled with an inverted-T-shaped cotton cushion, the large end of the cotton cushion is located in the anti-seepage ring, and the small end of the cotton cushion is located in the anti-seepage ring. A transparent shell located on the outer side of the water-absorbing dressing bag is fixed to the non-woven fabric, the upper end of the transparent shell is detachably connected with two elastic bands which are opposite left and right, and the free ends of the two elastic bands can be connected together. The drainage tube is ingenious in structure, enables the cotton pad to press the puncture hole, improves penetrating fluid absorption capacity, enables the puncture hole to be gradually shrunk or even closed, can reduce seepage of tube openings of drainage tubes of the chest cavity and the peritoneal cavity, reduces times of dressing change, and improves life quality of a patient.

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.
