CONSTITUTION:A heating furnace 2 with an operating lid 3 is provided on a device base, and a heat-resistant container supporting bed 4 on the inner side of the operating lid 3. Furthermore, electric heaters 5 are connected to the side and the bottom of a heating furnace 2 and a far infrared ray heater 6 is arranged on the upper surface of the heating furnace 2. In addition, a lid operating drive device 7, an intrafurnace temperature control device 8, a heating furnace shutdown time control device 9 and an intrafurnace generated gas deodorizing device 10 are provided. After this, the used syringe of synthetic resin and needle are stored in a heat-resistant container, and the container 1 is inserted into the heating furnace. Then the syringe is heated at a specified temperature from inside and outside the container 1 and the molten syringe is kept in that state for a specified time and sterilized. The molten substance is cooled and cured in the container 1 and allowed to contract. As a result, the used syringe is subjected to treatment of the remaining blood for safety and deformed in a state which allows easy dumping.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for disposing of used syringes and an apparatus therefor.

"Prior Art" Conventionally, attempts have been made to prevent secondary blood infections from used syringes by crushing and shredding used syringes and disposing of them. However, since such mechanical processing devices cannot contain or destroy blood, there is still concern about secondary infection during the handling stage.

"Problems to be Solved by the Invention" The present invention aims to safely dispose of used syringes and residual blood, and to transform them into a state that is easy to dispose of.

"Meaning for Solving Problems" The present invention stores used synthetic resin syringes and injection needles in a heat-resistant container, inserts the container into a heating furnace, and inserts the syringe into a predetermined position from inside and outside of the container. It is characterized in that it is heated to melt and sterilized by maintaining that state for a predetermined period of time, and then the molten product is cooled and hardened in the container, so that the outer periphery of the cured product shrinks smaller than the inner periphery of the container. This invention relates to a method for disposing of used syringes and an apparatus therefor.

"Operation" Therefore, a large number of used synthetic resin syringes and needles are put into the heat-resistant container 1, and the container 1 is placed on the support stand 4! When the heating furnace 2 is closed by operating the opening/closing drive device 7, the container 1 is accommodated in the furnace 2. In this state, the electric wire and infrared heater 5.6 are heated. The furnace temperature is set to the synthetic resin melting temperature and sterilization by the controller 8, and the heating time is set to a predetermined time by the closing time controller 9. The heating causes the syringe to melt and generate gas. This gas enters the deodorizing device 10 from inside the heating furnace 2 and eliminates the odor. Heating by the electric heater 5 heats the side and bottom surfaces of the container 1 and heats the syringe from the outside to raise the temperature of the inner surface contacting part of the container 1. permeates, thereby increasing the temperature of the center, heating the center and the periphery evenly, and increasing the temperature, sterilizing the remaining blood in the syringe and needle, and sterilizing it over a predetermined period of time. is sufficient, and then the drive device 7
is operated to open the furnace 2 and move the support stand 4 out of the furnace to cool and harden it, and the cured product is molded into the same shape as the bottom and side walls of the container 1, forming a block 34 containing a syringe needle. . This block 34 has a higher shrinkage rate than the container 1, and when hardened, its outer periphery becomes smaller than the inner periphery of the container 1, forming a gap 1it (FIG. 3). Therefore, the container 1
When the block 34 is removed from the support stand 4 and turned over, the block 34 falls from the container 1.

"Example" A reheating furnace 2 is provided with an opening/closing lid 3 on a machine base 11, and a support base 4 for a stainless steel heat-resistant container 1 is provided inside the opening/closing lid 3. The support base 4 may be the upper surface of the heat-resistant material of the lid 3 as shown in FIG. 1, or the upper surface of the horizontal heat-resistant material of the L-shaped opening/closing lid 3 as shown in FIG. In this manner, when the lid 3 is closed, the bottom surface of the heating furnace 2 is formed by the support base 4, and in FIG. An electric heater 5 is wired, and a far-infrared heater 6 is arranged on the upper surface. A screw rod 12 is connected to the outside of the lid 3, and the screw rod 1
2 with a female screw 13, a worm gear is formed on the outer periphery of the female screw 13, a worm 14 is engaged with the gear so as to be rotatable in the forward and reverse directions, and a forward and reverse rotation motor 15 is connected to the worm 14. By sliding the lid 3 in forward and reverse directions toward the opening of the heating furnace 2, the opening/closing drive device 7 for the lid 3 is formed. The closing time of the heating furnace 2 by the lid 3 is set by a timer-based time control device 9, and is set to about 45 minutes. Furnace temperature is measured by a temperature sensor 16 inserted into the furnace, compared with a set temperature of 180°C by a comparator, and calculated to operate a variable resistor 17 to adjust the current of the electric heater 5 to control the furnace temperature. A device 8 is formed. 1 and 2, a generated gas guide pipe 18 is provided on the ceiling side, one end of a heater pipe 20 containing a heating wire 19 is connected to the skeleton 18, and the other end is opened to the atmosphere. The inside of this pipe 20 is heated to a high temperature of 200 to 250°C, and a deodorizing bag WI for the gas generated in the furnace is used.
O is formed, and the generated gas passes through the pipe 20, whereby odor components are burned and deodorized. As shown in FIGS. 5 and 7, this deodorizing device 10 stores water 22 in a water tank 21, and connects a pump 24 to the bottom via piping 23, and connects the discharge port of the pump 24 to the upper surface of the water tank 21. By connecting the upper end of the ejector 25 penetrating through the heating furnace 2 with a pumping pipe 26, and connecting the generated gas guide pipe 18 penetrating through the ceiling of the heating furnace 2 with the middle suction port of the ejector 25 through a suction pipe 27. The generated gas may be sucked into the ejector 25, and the suction gas may be brought into contact with the water 22 together with the water ejected from the ejector 25, so that the odor components of the generated gas are absorbed into the water 22. In addition, 28 in the figure indicates a water supply port, 29 indicates an operating limit switch, 30 in FIG. This is the control panel that houses it.

"Effects" Since the present invention is based on the method described above, the used synthetic resin syringe is melted and hardened into the block 34, in which the needle is mixed and sealed, and this can be safely and conveniently disposed of. Any remaining blood will be sufficiently sterilized.

Furthermore, since the present invention is constructed as described above, the syringe or the like is heated from the inside and outside when placed in the heat-resistant container 1, rapidly melts, and can be heated at a predetermined temperature and for a predetermined time to sufficiently sterilize blood and extinguish generated gas. A safe used syringe disposal device that does not cause odor and harm the environment can be obtained.
