Title: Retention needle in vein
Inventor: SOTOMA YASUO
IPC: A61M5/32
Filed: 1992-02-22
Abstract: PURPOSE:To surely and easily pierce a retention needle in vein into a vein by slantly extending the cut end of the outer needle tip of the retention needle. CONSTITUTION:An outer needle tip 2 is slantly extended to shrink the difference in length between an outer needle 3 and an inner needle to the utmost and to provide the piercing capability of only the outer needle 3. When a retention needle in vein is pierced into a vein, the outer needle 3 can be inserted into the vein even if the inner needle is extracted when the extended outer needle tip 2 reaches a vein cavity, and piercing can be shortened by the quantity of the extended outer needle tip 2. In case of incomplete piercing that the outer needle tip 2 does not reach the vein cavity, the outer needle tip 2 has an angle, and the outer needle 3 can be advanced through a transit passage after the inner needle is extracted, and vein retention may possibly succeed. The danger of the failed installation action of the retention needle due to insufficient piercing can be reduced.

Abstract: PURPOSE:To improve a generation efficiency of discharge sparks in terms of the subjected device for an FF heater, by providing a second capacitor in addition to a discharge capacitor, and discharging discharge electric charges of the second capacitor into a charging cycle of the discharge capacitor so that they may serve as switching control signals. CONSTITUTION:A capacitor 4 for discharge energy accumulation is charged in a positive semi cycle of an AC power source 1 while a capacitor 9 is charged in a negative semi cycle. A differential discharge voltage of the both capacitors 4 and 9 are detected on an anode side of a diode 3. When a differential discharge voltage reaches a preset value, base currents of a transistor 13 flow during the discharge cycle to the capacitor 4 by way of resistors 2, 11, and 15 so that the transistor 13 may become conductive. As a result, a thyristor 6 is turned on so that accumulated charges of the capacitor 4 are discharged to an ignition transfer 5; thereby igniting. In this manner, discharge sparks can be generated at high efficiency.
