Abstract: A syringe needle destructor consists of a housing with a multiple-electrode type needle destroying device in the housing and an elastic needle supporting frame disposed above the housing over the destroying device. The frame consists of a sliding face plate with a needle inserting hole and an elastic frame body. The housing is provided with an opening to contain a number of electrode members of the destroying device. Two snap holes are provided on two sides of the opening to install the elastic supporting frame. The opposite inner edges of the snap holes are provided with spring grooves to support two springs of the supporting frame respectively. The needle destroying device has at least two electrode members in the housing connected to the power source. Different electrode configurations are disclosed.

Abstract: The present invention relates to an instant pressure-reducing process and device for a blood-gathering tube which comprises a blood-gathering tube in a state of normal pressure and a pressure reducing device, wherein the blood-gathering tube in a state of normal pressure comprises a tube body made of plastic or other cheap material and an elastic cork. One end of the tube body is an opening and another end is closed. The central part of elastic cork is thinner in favor of being pierced through by the injection needle head, the elastic cork is tightly nested into the opening of tube body under normal pressure so as to separate inside of the tube body from outside. The pressure-reducing device comprises an injection needle head and a pressure-reducing transformer at least. The needle head is nested into the pressure-reducing transformer.
