Description

Dishwasher rack

The subject of the innovation concerns a dishwashing machine carrier for hoses used in hospitals or laboratories, such as endotracheal tubes, suction hoses or the like, consisting of a flushing pipe that can be inserted into one end of a hose to be cleaned and a spring clamp that can be moved along the pipe with a pipe clamping part and hose clamping bracket.

In the case of automatic rinsing machines used in laboratories and hospitals, it is known that narrow-volume tubes, endotracheal tubes or similar are individually placed on rinsing tubes in

‘ form of spray nozzles, which are provided as separate washware carriers alongside other washware holders, such as basket inserts, wash sleeves or injector nozzles for surgical instruments, etc. in the dishwasher's dish or service trolley. Such wash pipes, which are to be adapted to the hose ends, have spring clips pushed on to secure the hose, which press against the flexible hose ends. If necessary, the height of the pushed-on spring clips can also be adjusted. During the rinsing and cleaning process, the rinsing liquid is sprayed under pressure through the pulled-on hose via the open nozzle end of the wash pipe, which cleans the inside of the contaminated hose. After the cleaning or rinsing process, the residual water from the hose can flow out via the leak in the hose coupling, after which a subsequent drying process can be carried out.

One problem with the known hose locking system using a spring clamp is that the attached hose or its end cannot be aligned centrally to the flush pipe axis due to the one-sided spring effect of the hose clamp, which means that inner wall areas of the items being washed are covered and therefore cannot be flushed sufficiently.

A further problem is that if the hose to be cleaned has an inner diameter that is much larger than the outer diameter of the associated flushing pipe, a column of water that flows optimally through the hose during the cleaning or flushing process may not be able to form if an excessive amount of flushing water branches off through a large leak at the open end of the hose, thereby weakening the main flow in the hose.

The innovation is based on the task of creating an opportunity for optimal internal cleaning in a dishwashing rack equipped with a clamping spring for hoses, whereby even different internal diameters of the hoses do not represent an obstacle.

According to the innovation, this task is solved by the features specified in claim 1. Advantageous embodiments and further developments of the innovation emerge from the following subclaims.

The innovative combination of the spring clip with a hose plug that takes into account different hose diameters makes it possible to optimally align and adapt hoses used in medical technology for rinsing in the washware carrier and to optimally flood them during the rinsing process, regardless of their respective inner diameter. This enables very good internal cleaning of the hoses.

An embodiment of the innovation is shown purely schematically in the drawings and is described in more detail below. It shows

Figure 1 shows a washware carrier designed as a flushing pipe for the internal cleaning of

Hospital or laboratory tubes used, such as endotracheal tubes or similar, in the view and

Figure 2 shows a hose plug of the spool carrier in plan view,

A dish carrier marked (1) in Fig. 1 serves to hold and retain a hose (2) used in the hospital or laboratory area, such as an endotracheal tube, suction hose or the like, which, after use, must be reprocessed inside and out in a special rinsing process in the dishwasher (not shown). Several such dish carriers (1) are arranged separately in the dish or service trolley (not shown) of the dishwasher, alongside other dish holders, such as basket inserts, rinsing sleeves or injector nozzles for surgical instruments, etc.

The dishwashing rack (1) has a straight flush pipe (3) for cleaning the inside of the hose (2) that is pulled on. A spring clip (4) with a pipe clamping part (5) and hose clamping bracket (6) is pushed onto it. The pipe clamping part (5) of the spring clip (4) has two spring legs (5a, 5b) that are almost V-shaped and extend transversely to the flush pipe axis and are designed with guide openings (7) for the flush pipe (3). The hose clamping bracket (6) is molded onto the upper spring leg (5a), and its bracket end (8) rests springily on the hose (2) or, if the hose (2) is not pushed on, on the flush pipe (3). The spring clamp (4) is held on the flush pipe (3) in a force-locking manner but can be adjusted in height by its spring tension effect and can be released from its locking position and moved on the flush pipe (3) by pressing the two spring legs (5a, 5b) together.

For the purpose of optimal cleaning of the inside of the hose, without different inner diameters of the hoses representing an obstacle, the innovation for centering and holding the attached hose (2) (Fig. 1) combines the spring clip (4) with a hose plug (9), Fig. 2, attached to the flushing pipe (3). The hose plug (9) is conical in shape to accommodate hoses with different inner diameters and is arranged on the flushing pipe (3) above the pipe clamp part (5) of the spring clip (4), whereby the hose clamp bracket (6) of the spring clip (4) springily grips over the hose plug (9).

To drain residual water from the flushed hose (2), the hose plug (9) has one or more drainage channels (10) for the flushing liquid on its conical surface, running in the axial direction of the flushing pipe (3). The hose plug (9) is arranged on the flushing pipe (3) so that it can be adjusted in height and is held on the flushing pipe (3) by friction via a central inner bore (11). The combination of the spring clip (4) with the hose plug (9) advantageously makes it possible to adapt hoses used in medical technology in a position that is optimally aligned for flushing in the washware carrier (1) regardless of their respective inner diameter, and therefore to clean them optimally in the flushing process.

A hose (2) prepared for internal cleaning, e.g. an endotracheal tube, is pulled with its hose end (12) over the flushing tube (3) and pushed onto the conical hose plug (9), which centers it in relation to the axis of the flushing tube (3). The hose (2) seals tightly with the plug, except for the intended leaks (drainage channels 10), whereby its inner walls (13) in the area of the inserted flushing tube (3) do not touch the tube and thus remain free for the flushing liquid to be fed through the flushing tube.

During the flushing process, a water column builds up unhindered in the hose (2) and optimally flows through the hose (2). At the end of the flushing, the remaining water flows out of the hose (2) evenly via the drainage channels (10) of the hose plug (9), whereby any dirt particles deposited at the hose end (12) are also advantageously flushed out. The unhindered buildup of a water column will occur equally for hoses with small or large hose inner diameters. With a typical pipe outer diameter of the flushing pipe (3) of approx. 4mm, series hoses with inner diameters of = 4mm, preferably up to 10mm, can be optimally adapted and cleaned inside using the conical hose plug (9). The hoses are cleaned from the outside in a conventional manner using flushing nozzles arranged on the emergency vehicle or using separate spray arms on the program-controlled flushing machine.
