Definitions
- the invention relates to a disinfection quiver for receiving a rigid endoscope, wherein in the quiver, a cleaning liquid is provided.
- Endoscopes should be cleaned after use as part of a medical examination or treatment.
- the endoscope is immersed in a disinfection quiver in which a cleaning liquid, in particular a disinfectant, is located.
- a cleaning liquid in particular a disinfectant
- the shaft of the endoscope touches the upper edge of the quiver and thus contaminates the edge. If, when the endoscope is pulled out of the quiver, the shaft of the endoscope is pulled over the outer edge of the quiver, the shaft is again contaminated. Thus, the cleaning process was free.
- the object of the invention is therefore to provide a disinfection quiver of the type mentioned in such a way that the endoscope to be disinfected therein is not contaminated again during the cleaning process.
- the disinfectant quiver from an outer Spülmatikeitsköcher (hereinafter abbreviated "rinsing quiver”) consists for receiving the cleaning liquid, in which a designed as a floating body Tauchgrocher is located, which immersed with the exception of its upper end in the cleaning liquid is and that the diving quiver by means of the endoscope is inserted into the rinsing quiver so far that the dipping quiver is completely immersed in the cleaning liquid.
- the dive quiver can be easily and safely pressed into the quiver, openings are formed according to an embodiment of the invention in the wall of the dip bag. Through these openings, the cleaning liquid can easily penetrate into a submersible quiver when immersing the dip bag into the cleaning liquid and also emerge from the dipping quiver when the endoscope is withdrawn.
- the bottom of the dip bag has a perforation. This makes it possible, on the one hand, for the endoscope with its distal end (with the tip) to be able to press the immersion quiver into the cleaning fluid and, moreover, for the perforated base to ensure a rapid inflow and outflow of the fluid when the immersion retainer enters and exits.
- the perforation of the soil favors when pulling out of the endoscope a quick puffing that is avoided by the free flow of fluid due to the perforation a buoyancy-inhibiting fluid difference between the outer and inner quiver. So the diving quiver can rise by his buoyancy following the endoscope to the top.
- the diving quiver consists of a material whose density (density) generates sufficient buoyancy of the diving bag in the quiver. With a sufficiently high buoyancy rate, this ensures that the endoscope does not touch the possibly contaminated edge of the toilet bowl when it is pulled out.
- the immersion quiver is designed as a hollow body.
- the compression spring is guided securely in the Spülgrocher, it has proven to be expedient that in the bottom of the Spülgrochers a recess is formed, in which the compression spring is supported.
- the buoyancy of the dive must be so large that the endoscope when pulling out of the diving quiver does not come into contact with the edge of the sink. This is particularly ensured when the buoyancy rate is so great that the diving quiver even at a rapid withdrawal of the endoscope (> 1m / sec) at least as fast expels that its upper edge surmounted the upper edge of the Spülköchers. It has proven to be expedient that the filling level of the cleaning liquid in the rinsing quiver is so high that when the dipping quiver is inserted into the quiver, the upper edge of the dipping pocket projects beyond the upper edge of the rinsing box.
- the filling level of the disinfecting fluid is expediently about 3/4 of the height of the rinsing bag.
- the upper edge of the dip bag protrudes beyond the upper edge of the outer bag when the endoscope is pulled out of the disinfection bag except for a residual length which corresponds to the diameter of the swimming or diving bag.
- a recess for receiving a laterally projecting light entry nozzle of the endoscope is formed in the upper end section of the dip bag.
- the recess in the immersion quiver has an upwardly projecting lateral wall portion.
- the immersion quiver has constricted portions on its inside.
- FIG. 2 shows in a longitudinal section an embodiment of a dive bucket according to the invention designed as a floating body
- FIG. 3 is a perspective view obliquely from above the immersion quiver shown in Fig. 2,
- FIG. 4 is a perspective view obliquely from below the immersion quiver shown in Fig. 2,
- FIG. 5 shows in a longitudinal section a disinfection quiver according to the invention with a dipping quiver inserted into a rinsing quiver
- FIG. 7 is a representation corresponding to FIG. 5 of the situation in which the endoscope pushes the dipping quiver down into the cleaning liquid, FIG.
- Endoscope is completely submerged in the cleaning fluid
- Endoscope is moved back up
- FIGS. 11 to 16 correspond in the illustration and arrangement to FIGS. 5 to 10 with the only difference that a pressure spring is arranged between the bottom of the rinsing bag and the immersion quiver used.
- FIG. 11 corresponds to FIG. 5 with inserted compression spring
- FIG. 12 corresponds to FIG. 6 with inserted compression spring
- FIG. 13 corresponds to FIG. 7 with inserted compression spring
- FIG. 14 corresponds to FIG. 8 with inserted compression spring
- FIG. 9 corresponds to FIG. 9 with inserted compression spring
- FIG. 16 corresponds to FIG. 0 with inserted compression spring
- FIG. 17 is a longitudinal section of another embodiment of a disinfection bag with an endoscope being inserted into the immersion quiver
- FIG. 18 shows a diving quiver according to FIG. 17, in which the endoscope is pressed down into the diving quiver
- FIGS. 17 and 18 shows a diving quiver according to FIGS. 17 and 18, in which the endoscope is inserted into its abutment until it stops.
- FIGS. 1.1 to 1.3 an exemplary embodiment of the prior art illustrates which problem is solved with the present invention.
- the quiver 1 shown in the figures is about 3/4 filled with a cleaning liquid (disinfectant solution) 2.
- a cleaning liquid disinfectant solution
- FIG. 1.1 the shaft 4 of the endoscope 3 comes into contact with the upper edge 5 of the quiver 1 and thereby contaminates the edge.
- FIG. 1.2 the shaft of the endoscope 3 is completely immersed in the cleaning liquid 2 in the quiver 1.
- the shaft 4 of the endoscope 3 is disinfected.
- FIG. 1.3 now shows, when the endoscope 3 is withdrawn from the quiver 1, the shaft 4 of the endoscope can be pushed over the outer edge 5 of the quiver and thus contaminated again. This would have been the cleaning process in vain.
- the invention now provides a disinfection quiver 6, which consists of a Spülköcher 7, in which a designed as a floating body additional immersion quiver 8 is inserted.
- This diving quiver floats in the washing quiver 7 except for its upper end portion 9 in the cleaning liquid 2 (Fig. 5).
- the immersion quiver 8 can be pushed into the rinsing quiver 7 by means of the endoscope 3 until the immersion quiver 8 completely dips into the cleaning liquid 2.
- the diving quiver 8 is shown in more detail in FIGS. 2 to 4.
- 8 circular openings 10, 11 are formed in the upper and lower regions of the wall of the dip tank, which support an inflow and outflow of cleaning fluid when entering and emerging in the quiver 7.
- the bottom 12 of the dip bag 8 is formed perforated.
- This floor 12 fulfills two tasks. On the one hand, it allows the endoscope 3 with its distal end (with the tip) to push the immersion quiver 8 into the cleaning liquid 2 and, on the other hand, ensures rapid inflow and outflow of the liquid when the immersion pocket 8 enters and emerges.
- the perforation 13 of the bottom 12 favors a quick expulsion when the endoscope 3 is withdrawn, because due to the free outflow of the liquid 2 due to the perforation 13 a buoyancy-inhibiting liquid level difference between the flushing quiver 7 and the inner immersion quiver 8 is avoided.
- FIG. 6 shows the moment when the endoscope 3 is inserted into the diving quiver 8.
- the shaft 4 of the endoscope 3 touches the upper edge 14 of the inner submersible bag 8. This is contaminated.
- Fig. 7 shows the moment in which the diving quiver 8 is pressed by the endoscope 3 in the cleaning liquid 2 down. If the immersion quiver 8 is pressed completely into the quiver 7, then, as FIG. 8 shows, it is completely covered with cleaning liquid 2. This ensures that even the edge 14 of the dip bag, which could possibly be contaminated by the endoscope 3 used, cleaned (disinfected) is.
- Fig. 9 shows the retraction of the endoscope 3 with the result that the diving quiver 8 also moves upward due to its buoyancy. If the buoyancy of the diving bag 8 is sufficiently large, the diving quiver is moved out of the flushing quiver 7 so fast that the shaft 4 of the endoscope 3 touches only the upper edge 14 of the diving bag and does not contaminate the possibly contaminated edge 5 of the washing bag 7 (FIG. 10). In order to ensure this mode of operation, the buoyancy rate of the immersion pocket 8 must be so great that the endoscope 3 can never touch the edge 5 of the flushing pocket 7 when pulled out.
- a sufficient buoyancy can be achieved either by a suitable choice of material by the immersion quiver 8 consists of a material whose density produces a buoyancy of the immersion tank in the Spippoköcher 7, or the Tauchgrocher 8 may be formed as a hollow body, which has the same effect.
- a compression spring 15 may be arranged in the lower region of the mud box 7, at which the immersion quiver 8 immersed in the mud quiver 7 is supported.
- the compression spring 15 is securely guided in the rinsing quiver 7, a recess 16 is additionally formed in the bottom 12 of the Spülköchers 7, in which the compression spring 15 is supported. This is shown in FIGS. 11 to 16. These figures differ from FIGS. 5 to 10 only by the additionally arranged compression spring 15.
- FIGS. 17 to 19 show a further embodiment of a disinfection bag 17, in which an open-top lateral recess 19 is formed in the upper region of the washing bag 18, the bottom 20 of which has a bearing surface 21 for a laterally projecting section 22 of the immersion bag 23 inserted therein forms.
- the laterally projecting portion 22 of the dip tank 23 expediently has an inclined support surface 24, which has an approximately same inclination angle as the support surface 21 of the Spülköchers 18.
- a recess 26 is formed, in which a laterally projecting light inlet nozzle 27 of the endoscope 3 can engage.
- the recess has an upwardly projecting lateral wall section 28.
- the shaft 4 of the endoscope 3 can be immersed in the rinsing box 18, but also its other parts such as the middle part, the light inlet nozzle 27 and the Okulartrichter 29.
- the immersion quiver 23 has narrowing sections 30 and 31 on its inner side.
