Definitions
- the present invention relates to a Sterilisiersiebschale, also called screen basket, such as a sterilization or disinfection screen basket, according to the preamble of claim 1.
- Sterilisiersiebschale also called screen basket, such as a sterilization or disinfection screen basket, according to the preamble of claim 1.
- Generic screen baskets are used to in a
- AEMP Processing unit for medical devices
- a screen basket has the primary task, in his Siebkorbinneren several
- a screen basket should have as few or no sections as possible, in which cleaning liquid (i.e., water added with additive) used during the cleaning process collects, so that the filter cartridge used
- Cleaning liquid drains as completely as possible from the strainer basket after the cleaning process.
- screen baskets should be careful not to break or crack, even after intensive use, during which they are exposed to shock and cutting stress, minimizing the risk of injury and cutting an operator.
- a screen basket which is adapted for receiving objects to be disinfected or sterilized.
- the screen basket has a bottom, in particular a sheet metal bottom, which, with a variety of
- the floor has a ground plane bounded by sidewalls.
- This ground plane is designed as a kind of perforated plate plan.
- a mat is inserted into the screen basket. This mat prevents the drip basket from dripping efficiently, so that even after removing the strainer basket from the RDG, any residual water will disturb the humidifying of various strainer basket areas, in particular the
- Wire mesh configured instead of a perforated plate.
- a wire mesh has a corrugated ground plane, the slipping or slipping of the recorded
- a wire mesh causes fewer surface contacts, for example, with a flat surface and consequently a lower capillary action.
- strainer wire mesh is that not only residual water but also dirt accumulates in the individual nodes of the braid. Furthermore, inevitably occurs in a wire mesh after appropriate period of use Breaking or detachment of the individual wires, which significantly increases the risk of injury emanating from a Siebkorb-wire mesh.
- the wall perforation corresponds to the bottom perforation.
- the baskets of the prior art all have the disadvantage that they cause disturbing even after removal from the RDG of adhering residual water caused further surfaces. Furthermore, they have, depending on the embodiment about the disadvantage of increased risk of injury, the disadvantage of slipping or slipping of the recorded objects and / or the disadvantage of contamination or the accumulation of germs.
- the object of the present invention in view of this prior art, is to remedy or at least mitigate the disadvantages of the prior art, and in particular to provide a strainer basket which drips efficiently, so that it is (almost) non-irritating after removal from the RDG
- Sieve bottom processed plan perforated plate if necessary, reduced the contact area between the strainer and a flat surface and thus could improve the overall dripping behavior, however, the production of such a special plate would be costly and expensive and thus uneconomical overall.
- the spacer feet / nubs would be at a certain distance from each other over the
- Forming contact areas in the form of correspondingly three-dimensionally extending plate webs between the plate holes / retrofit, such as by the first plane perforated plate is subjected to a corresponding deformation step.
- a slipping or slipping of the recorded objects can be prevented even without inserting a (silicone) mat.
- the subject of the invention is accordingly a sieve basket for the purpose of being disinfected or sterilized (generally: to be cleaned) medical
- a medical article is understood to be one which has its use, for example, in surgery or in a related medical field.
- ground plane refers to a plate with almost constant thickness extending in two main spatial directions.
- the bottom of the bottom plate or sheet receives a three-dimensional, varying structure that deviates from that flat plate with the constant plate thickness. It is advantageous not to form the bulges / bulges in the macro range, i. to form a single indentation / bulge over a plurality of number of lands, but to provide the microinjection / bulging, i. the denting / bulging
- the invention can be described functionally such that the screen basket has a bottom made of sheet metal (perforated plate / perforated plate), which (by
- the inventive idea lies in the fact that by forming a braid-like hole sheet on the one hand slipping the to be cleaned
- the bottom of a plurality of in the ground plane in each case parallel extending L jossstrebencruparen / Leksstegcruen and cross strut pairs / Querstegcruen constructed in the ground plane preferably perpendicular (or at a different angle) to each other, so that the bottom of a lattice structure with for example, rectangular
- the openings when viewed through the openings in the ground plane, the openings have a rectangular shape and form a three-dimensional roof shape (or butterfly shape) of the two triangles through the corrugations or bumps to Siebkorbinneren and / or Siebkorbutereren, which in each case in a plane opposite to each other Gradients are formed, that of the
- the (hypothetical) vertex of the roof shape preferably extends in each case between two diagonally arranged nodes of a grid structure of the ground, as has already been explained above.
- a further advantageous embodiment is characterized in that in each case a web / strut pair of two struts with a waveform is formed in order to form the corrugations or indentations / bulges.
- each strut / strut has for itself (approximately) a sinusoidal shape, ie the shape of a sine function, in order to ensure that it protrudes into the strainer basket interior or protrudes into the strainer basket exterior.
- the one strut of a strut pair (approximately) reflects the course of a sine function and the adjacent strut the course of a cosine function, wherein the x-axis of those functions corresponds to the parallel strut pairs.
- one strut has a sine shape
- the adjacent strut of the strut pair has a cosine shape or is phase-shifted by half a pi in the course.
- the preferably smooth, i. even side walls also openings / holes / pores, but differ in their shape and size of the perforations / holes of the bottom optionally.
- the perforations / holes in the side walls are smaller / more fine mesh to design than those of the bottom, to protrude from the screen basket in the recorded objects from the
- the invention thus allows a flexible adaptation of the individual surfaces (floor / side surfaces) to their respective (partial) functional area.
- the mesh simulation differs in the desired manner from a mesh to the disadvantage of a braid, namely the dirt-enriching Overlap at the nodes, not to take over in the braid simulation, so that the sheet metal floor according to the invention simulates / imitates / maps / projects the advantages of a braid, without bringing its disadvantages.
- the metal floor forms both to the inside, as well as to the outside of each point contacts, which develop no residual liquid attracting capillary action.
- the floor further advantageously has such a structure that a hypothetical connection line of the bottom nodes projecting towards the screen basket extends diagonally to the grid structure (ie diagonally through the openings in the ground plane) and at right angles to a hypothetical connection line to the screen basket exterior protruding bottom node runs.
- an advantageous embodiment of the strainer is characterized in that caused by the corrugations or dentures three-dimensional soil structure, such as ribbing, investment and
- fixation surfaces to be inserted into the screen basket items, which increases the positional stability of the recorded items. It is therefore no (silicone) mat to lay on the ground to ensure a secure, positive adhesion of the individual items.
- Fig. 1 a perspective view of a screen basket
- FIG. 2 the area indicated by II in FIG. 1 enlarged schematically;
- Fig. 3 the area indicated by III area of Fig. 1 schematically
- FIG. 4 is a perspective view of a mesh-imitated floor
- FIG. 6 shows a detail of the strainer basket with inserted objects.
- Fig. 1 shows a screen basket 1 for receiving objects to be cleaned, with a plurality of openings 2, as can be seen in the detail view of FIG.
- the present case with a rectangular base / ground level screen basket 1 has a bottom 3 and from each side edge outgoing, in this case four, side walls 4.
- the bottom 3 is designed as a sheet metal part, which, as can be seen in the detail view from FIG. 3, has periodic corrugations or indentations 5. These corrugations 5 protrude from the ground plane to Siebkorbinneren 6 and in the present case also to Siebkorbutereren 7 out, so that the sheet metal part / the bottom of a
- the bottom 3 has a lattice structure in the projection. This consists of a plurality of in the ground plane, i. in the present plan view, respectively parallel longitudinal strut pairs 8 (also called longitudinal web pair) and cross strut pairs 9 (also called cross bar pair) together.
- a single longitudinal strut pair 8 is composed of two longitudinal struts 10, 11 together. These longitudinal struts 10, 11 extend in the ground plane, ie in the present plan view, parallel to each other. When viewed spatially (see Figures 3 and 4) it can be seen that each strut 10, 11 in the third spatial direction, namely towards Siebkorbinneren 7 and / or Siebkorbäußeren, one another
- a single cross strut pair 9 is composed of two transverse struts 12, 13 together. These transverse struts 12, 13 extend in the ground plane, i. in the present plan view, parallel to each other. When viewed spatially (see Figures 3 and 4) it can be seen that each strut 12, 13 in the third spatial direction, namely towards Siebkorbinneren 3 and / or Siebkorbutereren out 7, one another
- the area spanned by the openings 2 performs two functions. Firstly, it releases a contact and fixing surface 14 at the edge surface of each strut 10 to 13 which faces towards the aperture 2. This area 14 increases with the size of the apertures 2. The larger the objects to be inserted, the greater consequently the perforations 2 are to be designed so that sufficient contact and fixing surface 14 is released. Second, the allows of the
- Openings 2 spanned surface dripping out of the cleaning liquid from the strainer basket 1 out. Also, the drip function increases with the size of the
- Openings 2 spanned area set in it must be small enough to prevent Fieraus fallen to be cleaned devices.
- the grid structure defined by the floor 3 has floor nodes 15. According to the invention, these bottom nodes 15 are not in the same plane, since the corrugations 5 are formed.
- a particular advantage of the invention unfolds in that the bottom nodes 15, which are each formed by the cutting of a longitudinal strut 10, 11 with a transverse strut 12, 13, have approximately the same material thickness as the respective longitudinal or transverse strut 10 to 13.
- the mesh simulation according to the invention not only makes it possible to imitate a mesh, but also has the advantage over mesh that there is no overlap, ie doubling of the material thickness, but the same constant material thickness as in the rest of the floor.
- two further characteristics of the present invention are introduced.
- bottom nodes 15 such bottom nodes 15, which according to a
- advantageous embodiment of the invention are each arranged at the same height and protrude into Siebkorbinnere 6. They represent a wave crest 18 (see FIG. 3) of the periodic corrugations 5, so to speak.
- the base nodes 15 connected by the second hypothetical connecting line 17 represent those base nodes 15 which, according to an advantageous embodiment of the invention, are each arranged at the same height and protrude towards the screen basket outer 7. They represent, so to speak, a wave trough 19 (see FIG. 3) of the periodic corrugations 5.
- FIG. Fig. 3 shows a sectional drawing through the bottom 3 (see area III of Fig. 1).
- the strut shown here represents a longitudinal strut 10, 11, which structurally but in their basic form does not differ from a transverse strut 12, 13.
- a first transverse strut 12 branches off from each corrugation peak 18 of the longitudinal strut 10, 11, while a second transverse strut 12 emerges from each wave crest 19
- Cross strut 13 goes off.
- the reciprocity of the wave peaks 18 and wave troughs 19 described above can be easily recognized here.
- the longitudinal strut 10, 11 in this case has an angular course. However, this form has only exemplary character. In other embodiments
- FIG. 3 furthermore shows that the material thickness of the bottom knot 15 does not exceed that of the remaining longitudinal strut 10, 11, as a result of which, despite the braid simulation, there is no unfavorable overlap of the struts, as was described in the introduction.
- the corrugations 5 are shown in perspective.
- the first hypothetical connection line 16 (see Fig. 2) connects the wave crests 18, the second hypothetical connection line 17 (see Fig. 2) connects the wave troughs 19.
- the three-dimensional roof shape formed between four adjacent floor nodes 15 is composed of two triangles , The apex of those triangles can, depending on the consideration, between the two wave crests 18 of the four adjacent floor nodes 15 set (then the roof is closed to Siebkorbinneren 6) or between the two troughs 19 of the four adjacent floor node 15 set (then the roof towards Siebkorbinneren 6 open towards and closed Siebkorbutereren 7 out).
- Fig. 4 shows that the surface formed by the apertures 2, which in the projected plan view of Fig. 2 shows a rectangular lattice structure, has a high degree of spatiality in perspective, which tends to wetting that surface of drops after removal from the RDG
- the structure caused by the corrugations 5 provides sufficiently large contact and fixing surfaces 14.
- Fig. 5 shows the three-dimensional corrugations 5 as well as those of them
- Fig. 6 illustrates a portion of a strainer basket 1. Therein are several
- the strainer 1 has, in addition to the bottom 3, the side walls 4. These also have openings 21, which, however, may differ geometrically from those in the bottom 3. In the present case, the openings 21
- the side walls 4 are also possibly smooth, ie explicitly designed not wavy.
