A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable hand piece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. The reusable hand piece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. A saline valve positioned by the reusable hand piece communicates a saline supply through the probe assembly to perform saline flush of the cutter tube and outer cannula.

The present invention describes IV regulators that allow interruption of normal controlled-flow for a safe and convenient bolus flush, either for a specific period of time or for a specific volume of saline flush. Two time-controlled IV regulators are shown, one employing a pneumatic cylinder counter-opposed by elastic band(s) for administering a bolus flush, and one employing a compressible lever and torsion spring counter-opposed by a rotary damper. In both cases the mechanisms disengage the roller-clamp from the IV tube for a predetermined amount of time to fully open fluid flow there through for a bolus flush before return to the regulated-flow position. The volume-controlled flow regulator employs two internal bladders and allows one bladder to fill while the other bladder drains (and vice versa) by flipping a slider paddle-type toggle, thus enabling the administration of a set volume of flush fluid.

The invention discloses a self-laying type saline-alkali land tree pit flushing system, which comprises a main pipeline, branch pipelines and an automatic laying device, wherein the main pipeline is connected with a water pump, and the branch pipelines are connected with the main pipeline; the automatic laying device comprises driving platforms and driven platforms, each driving platform is arranged at the end of the corresponding branch pipeline, and each driven platform is arranged at the bottom part of the corresponding branch pipeline; traveling wheels are respectively arranged at the bottom parts of the driving platforms and the driven platforms; after a traveling motor on each driving platform is started by a control part, the automatic laying device walks, the connected branch pipelines are driven to expand, the driven platforms on the branch pipelines also walk, and the pipeline is automatically laid; after the pipeline is laid, because an automatic flushing part comprises a plurality of spray pipes which are connected with the branch pipelines, water can enter a spray head to flush a tree pit through the corresponding branch pipeline. The self-laying type saline-alkali land tree pit flushing system has the advantage that the tree pit flushing pipeline can be automatically laid, and the conveying of water is not needed, so that the labor intensity is decreased, and the labor force is saved.

The invention discloses a method for controlling volatile components of shallots in vacuum freeze-drying, and belongs to the technical field of vegetable food processing. The main processing process is as follows: first select the green onion raw material, wash, remove the stalk, remove the clothes, cut, rinse, soak in microwave to kill enzymes, drain, vacuum freeze-dry, cool, and pack. The invention adopts techniques such as washing with salt water, impregnating trehalose, and inactivating enzymes with microwaves, so as not to change the quality of vacuum freeze-dried shallot products, and at the same time, it is more conducive to the preservation of allyl sulfide and volatile capsaicin.

The invention discloses a preparation method of a medical porcine or bovine pleura biological dressing, which comprises the following steps: (1) selecting healthy adult swine or cattle, slaughtering, and integrally taking down the parietal pleura; (2) removing the incidental fat from the pleura; (3) soaking to disinfect the pleura having the fat removed in a disinfection liquid, and rinsing out with sterile normal saline; and (4) under sterile working conditions, putting the disinfected and rinsed pleura into a medical plastic bag, adding a proper amount of skin storage liquid into the bag, and refrigerating for later use, wherein the product is preferably used within one week. The preparation method disclosed by the invention has a simple process, and raw materials can be easily acquiredfrom wide-range sources, so that the preparation method can be easily completed by grass-roots medical treatment units. The prepared pleura dressing is low in cost, is relatively stable in size specification and flexibility and has high transparency, thereby providing convenience for observing the change of a wound surface; the prepared pleura dressing has soft texture and good elasticity and randomness, has less reject reaction on the wound surface and can not cause the occupation problem; and the prepared pleura dressing can relieve the pain of the burning wound surface, reduce the exudation of the wound surface, protect the wound surface, promote the healing of the wound surface and lower the scar hyperplasia degree.
