Abstract

PURPOSE:To dispose medical appliances after perfect sterilizing treatment by heating the exhaust gas discharged from an exhaust duct to deodorize the same. CONSTITUTION:A case 4 is received in a main body box l and a door 3 is closed to drive heaters l, 17, 22. Whereupon, the medical appliances 6 in the case are heated by a heater 2 to be melted. At this time, the medical appliances 6 melted under heating are pressed by a press plate 6 to be compressed. In this case, since the press plate 16 is also heated by the heater 17, the medical appliances 6 are rapidly melted. When the medial appiiances 6 are melted, gas is generated to leak to the main body box l from the case and discharged to the outside from an exhaust duct 19 but, on the way of discharge, said gas is heated by the heater 22 to be burnt perfectly and also deodorized by a deodorant 21.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for disposing of medical instruments such as used syringes.

(Background of the Invention) Medical instruments such as syringes used in medical institutions such as hospitals are made of synthetic resin or glass, and used medical instruments are disposed of by crushing means.

However, with these processing methods, it is not possible to completely sterilize blood and chemical solutions that adhere to medical instruments, and there is a risk of secondary infection due to waste, and waste must be handled with care. It was something.

Therefore, it is an object of the present invention to provide a means by which medical instruments can be completely sterilized and disposed of.

(Means for Solving the Problems) The present invention includes a main body box 1 provided with a heater 2, a case 4 installed inside this main body box 1, and a medical instrument 6 housed in this case 4 on a press board. 16, an exhaust duct 19 for exhausting gas leaked from the case 4 into the main body box 1 to the outside of the main body box 1, and heating and deodorizing the exhaust gas discharged from the exhaust duct 19. The deodorizing means 20 constitutes a medical instrument processing device.

(Function) In the above configuration, the medical instrument 6 housed in the case 4 is heated and melted by the heat generated by the heater 2 of the main body box 1. Further, the heated and melted molten material is pressed and compressed by the pressing means 10. At this time, the gas leaking from the case 4 into the main body box l is discharged from the exhaust duct 9, but on the way, this exhaust gas is heated by the deodorizing means 20 to completely burn it and deodorize it.

When the pressing of the molten material is completed, the drive of the heater 2 is stopped to solidify the molten material, and the solidified material is taken out from the case 4 and disposed of.

(Example) Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of the processing device, and FIG. 2 is a sectional view. l
is a main body box, and the inner wall thereof is equipped with a heater 2 such as a nichrome wire. 3 is a door that can be opened and closed.

4 is a case installed inside the main body box 1. The case 4 is made of a material that is hard to corrode and has high strength, such as stainless steel, and a used medical instrument 6 such as a syringe is stored inside the case 4. 5 is a handle, and 8 is a cart for transporting the case 4.

10 is a press means, which includes a motor 11, a gear 12.13 driven by the motor 11, a vertical feed screw 14 inserted into the gear 13, and a shaft 15 connected to the lower part of the feed screw 14. , shirt) 15 supported by a press plate 16. This press plate 16 has a built-in heater 17 such as a nichrome wire. Further, the motor 11 is installed on a frame 18 provided at the top of the main body box 1.

Reference numeral 19 denotes an exhaust duct erected on the upper surface of the main body box 1, and a deodorizing means 20 is provided inside the exhaust duct. This deodorizing means 20 includes a deodorizing agent 21 and a heater 22. 23 is a filter. As this deodorizing agent 21, a material having high heat resistance such as ceramic particles is used.

This apparatus has the above-mentioned configuration, and the processing method will be explained next.

A case 4 containing used medical instruments 6 is placed on a trolley 8 and transported to a main body box 1. Next, the case 4 is stored inside the main body box 1, the door 3 is closed, and the heater 2 is closed.
, 17.22. Then, the medical instrument 6 inside the case 4 is heated by the heater 2 and melted. At this time, the press plate 16 presses down the medical instrument 6 from above. Then, the heated and melted medical device 6 is pressed onto the press plate 16.
Compressed by In this case, the press plate 16 also
7, the medical device 6 melts quickly.

When the medical instrument 6 is heated and melted, gas is generated, and this gas leaks from the case 4 to the main box 1 (see arrow N). This gas is discharged to the outside from the exhaust duct 19, but on the way there, it is heated by the heater 22 and completely combusted, and is deodorized by the deodorizer 21.

Once the medical instrument 6 has melted, drive the motor 11 to
While raising the press plate 16, the heaters 2, 17 .
22 is stopped. Then, the molten material in the case 4 is gradually cooled and solidified. Then, the door 3 is opened, the case 4 is taken out from the main body box l onto the trolley 8, and the case 4 is transported to a predetermined location, and the solidified material inside the case 4 is discarded. Note that the temperature and heating time of the heaters 2, 17, 22 are appropriately set depending on the type of medical device 6, especially the material. ℃, and the processing time is about 40 minutes.

(Effects of the Invention) As explained above, the present invention includes a main body box equipped with a heater, a case installed inside the main body box, and a press means for pressing medical instruments housed in the case with a press plate. A treatment device for medical instruments is composed of an exhaust duct for discharging gas leaked from the case into the main body box to the outside of the main body box, and a deodorizing means for heating and deodorizing the exhaust gas discharged from the exhaust duct. This allows used medical instruments to be completely sterilized and disposed of.

Furthermore, since medical instruments are melted and solidified, they are easy to dispose of, and the gases generated as a result of melting can be completely disposed of.
