DE2621750A1 - Treatment of infectious rubbish esp. from hospitals - applies disinfection by use of hot air, steam IR or eddy current heating - Google Patents

Abstract

Rubbish and waste products from medical institutions is liable to contain infectious media which need to be neutralised by sterilisation so that the rubbish can be handled as normal domestic waste. The necessary disinfection is achieved continuously or discontinuously using a hot air chamber which is cylindrical in shape and is rotated while in an inclined position. A crushing or similar fragmentation process facilitates the passage of the disinfection medium. A metal heating unit employs IR radiation, or eddy current heating is employed. A press is placed at the outlet in order to reduce the volume of the emerging disinfected waste.

Description

Procedure for the disposal of infected (infectious) waste,

especially from hospitals.

The rubbish that arises in hospitals, medical practices, etc. is marked through the possibility of being a carrier of pathological germs to the source of infection to become. Therefore it is compulsory to read garbage on the hospital premises to destroy.

Otherwise this MUII contains parts, e.g. glass or plastics, dle make a combustion very difficult, especially considering environmental protection only with enormous additional effort (filter and gas scrubbing).

The invention proposes to disinfect and disinfect pathological MUII to be treated like household waste, i.e. to be deposited in an orderly manner or to be mashed together incinerate with household waste from other sources.

The disinfection of devices and devices is state of the art (Helss air of 180 ° C, moist heat of 120 ° C / 1atü or high pressure steam 134 ° C / 2atü.

According to the invention, a hot air or hot steam chamber can be used for this purpose in which the garbage is placed in bins.

Preferably, every continuous operation should be striven for: For this purpose, according to the invention, a tubular hot air (or hot steam) Chamber used, which rotates at an inclined position and is constantly transported and so the Ensures that the items to be disinfected will lapse over time. So treated Waste is pressed at the exit - if necessary to increase its volume - for normal waste disposal guided.

Basically, the appropriate interpretation is the technical one Data ensures perfect disinfection. For a better flow It should also be possible to obtain narrow cross-sections before or during the disinfection process a fragmentation should be provided, for example in the form of elnes mahiganges. Special problems offer metallic tubes such as syringes and hollow needles, in which e.g. Dried blood-smeared residues are contained. These would be the mowing process Borrow, yes even cause additional problems with cross-section bruises.

To solve this problem, an infrared radiation source can odo Eddy current heating additionally spec. for heating the necessary for disinfection Metal parts.

Claims (8)

Claim: Process for the disposal of infected (infectious waste characterized in that: 1) The garbage is made free of gums by disinfection and then can be treated like normal household waste. 2) After 1) disinfection through a hot air chamber in discontinuous Operation is achieved. 3) After 1) discontinuously through a superheated steam chamber. 4) According to 1) and 2) or 3) by rotating tubular, possibly inclined chamber through which the garbage is continuously transported can be. 5) According to 1) and 2) or 3) a shredding device is built in Is that facilitates access to the disinfection medlum. 6) According to 1) and 2) or 3) if necessary 4) and / or 5) an additional metal heating device is provided by infrared rays. 7) According to 1) and 2) or 3) if necessary 4) andZ or 5) and 6) by hot-air heating is achieved. 8) According to 1) - 7), with a press at the exit to reduce the volume is connected downstream.
