DE20304082U1 - Vacuum cabinet for cleaning and preparation of medical endoscopes, e.g. endoscopes used for gut inspection, has a U-shaped profile in which the endoscope is stored during cleaning under vacuum - Google Patents

Abstract

Vacuum cabinet for the cleaning and preparation of an endoscope has a U-shape in which the endoscope is hung with cleaning agent supply and removal connecting and a vacuum connection. The cabinet is covered and sealed with a gas-tight cover.

Description

1. Vacuum cabinet shape for the preparation of Endoscopes according to claim 1 Previous systems for endoscope processing work manually or semi or fully automatically similar to tub systems or commercial Dishwashers.

The devices haven't turned out that way yet strongly differentiated in terms of development in the task assigned to them , so they consume more chemicals and are not environmentally friendly.

It's higher costs in every way estimated for each processing cycle.

With this stand version stronger negative pressure applied. This results from the static pressure of the liquid column. The applied vacuum brings the liquid level approximately Cabinet height.

The negative pressure supports in a positive way the device tightness , Conversely, leaves the seal on endoscopes - like e.g. for watches - in a great depth of liquid so high pressure after. It can easily leak with harmful Consequences come.

The endoscope is used for reprocessing Completely into the acting liquid immersed.

The endoscope, which e.g. for a colonoscopy has been used, is pre-cleaned according to general requirements. Then it gets into the vacuum cabinet shape for reprocessing endoscopes hooked.

The U-profile comes with the lid tightly closed and the vacuum phase can begin. By The desired liquid in this hollow system rises under negative pressure until the endoscope is complete is immersed. The negative pressure and the liquid level are determined by the desired Exposure time held.

By eliminating the negative pressure flows the liquid back again in the appropriate tank or waste water.

The exact process of the Application of the liquids results from the instructions for use of the chemical and endoscope manufacturers.

The final step is the final rinse and drying the endoscope outside like inside (channels).

The inner canal system of the Endoscopes exposed to these liquids. For this purpose, the endoscope is hooked into the profile so that hollow pins are in the openings of its inner channel system and through which the inner channels are flushed out.

Air bubbles must not be present because the disinfection result deteriorates.

The bottom line is an inside and sterile outside, chemical-free, dry endoscope, which then without problems at the next Patients can be used.

It is easier and safer Hang the endoscope in a cabinet. Endoscopes are very sensitive instruments.

The closet is also more space-saving.

Is used instead of the U-profile worked a half-pipe, so results with the lid on a tight, closed tube.

If the cover profile is already in the cabinet door is installed, so is the closing of the cabinet at the same time also the lid is placed tightly on the U - profile or the half tube. The U-profile or the half-tube or the lid have a shape that that of the to be processed Endoscope corresponds. This also has the advantage of being between the endoscope and form a narrow space only, which helps fluid and thus save expensive chemicals. Lid and U-profile are sealed by means of a seal in the closed state. Neither the vacuum still the liquid or gases escape.

To do this, the lid or U profile additionally a lever or screw closure, the pressure on the seal exercises.

Added to this is the sealing moment the negative pressure that presses the lid onto the U-profile.

The vacuum has many advantages and impact

• - he eliminates fine gas bubbles in the liquid as a result of this of vacuum get bigger and thus easier from the liquid rising up.
• - he serves especially for the endoscope as a leakage protection, since this is the pressure of the liquid is balanced on the endoscope.
• - he additionally presses the lid on the U-profile.
• - he helps to significantly improve the disinfection result because of germs more sensitive to the disinfectant when exposed to negative pressure react.
• - the Vacuum can be controlled by control valves e.g. at the beginning and end of the U-profile can still be varied, that is , it can be started up easily so that it can be tested for leaks corresponds or equals. To do this, efficiency of disinfection elevated and thus the chemical consumption is reduced.
• - at the drying causes an acceleration: faster Evaporation of the rinsing liquid.
• - On Alternation of pressure and vacuum is possible and accelerates the Drying process at a low temperature.

The suspended endoscope is successively immersed in various liquids from separate tanks for a certain period of time due to negative pressure. The liquids can be passed through reusable systems. Also, by means of automatic program control, different liquids with different tasks can act on the immersed endoscope in turn, after which they return to the tanks provided flow or be discharged into the drain.

The system can be controlled that the liquid after the negative pressure has disappeared into the associated tank or into the drain or disposal tank flows back.

When hanging the endoscope in the cabinet or the U-profile, the hollow pins in the cylinder of the endoscope introduced right away or connected. about the hollow pins are the inner channels of the endoscope with the outer system connected. Measurements of the individual are also made using measuring probes channels of the endoscope possible. This Measurements clarify whether the inner canal system is free, narrowed or is even locked. Depending on the choice, liquid can be applied via the hollow pins with pressure or negative pressure in the inner channel system of the endoscope and clean and disinfect it. By means of pulsed liquid flows the effect of these measures and operations still increase. With such pulsed pumps, special measurement processes discharge or more easily remove gas bubbles and particles.

The hollow pins can have special holes or Have profiles that create vortices in the liquid. Through the Vortex there is practically a seal as there is a forward flow is slowed down by eddies.

A standing cupboard-like Form is for the handouts of the staff more convenient and compact than one lying arrangement of the endoscope. The dimensions of the closet can be small hold when the U-profile, which receives the insertion part of the endoscope, is designed curved.

The vacuum cabinet shape for reprocessing of endoscopes allows it to be in a favorable temperature range work that prevents the generation of harmful vapors and thus to Helps keep employees healthy. Possibly. resulting minimal Amounts of steam can be filtered out or discharged to the outside.
