Description

The The invention also relates to a portable application as trays and a process for product preparation and Produktdarreichung. The invention includes transportation and use on site.

Trays and machine inserts are in the field of reprocessing, medicine in particular in dental technology or in restaurant operations as well as in general the processing of instruments and are state of the art.

Trays and stakes be about it also widely used in the transportation of medical devices as well as in the household and in canteen kitchens. Trays have to be clean and reusable. The usual trays have, for example only the function of transporting or positioning products. Special processing operations z. B. in machines are used in reprocessing of medical devices as well as in the household and in canteen kitchens.

A solution in the form of a tray was in the US 5743734 Patent document shown. A portable instrument holder for dental instruments is described here. However, this cannot be used for cleaning and cannot be used for instruments with cavities or can be placed in an ultrasonic bath. Further inadequate solutions for dental instruments can also be found in the DE 196 46 024 C2 Patent application.

was standing Removable machine inserts are made of today's technology Stainless steel nets or perforated sheet steel, sometimes also with a bracket. These sieves are placed with the instruments in ultrasonic baths, for example. This is followed by further cleaning steps in dishwashers. A vote and significant change treatment conditions and validation of cleaning procedures and traceability is not guaranteed. Extremely disadvantageous With the current processes, the necessary repackaging is repackaging and sorting the products because the instrument inserts are either unwieldy or only with bulky accessories like trolleys etc. are portable. Product damage and product mix-ups cannot be avoided in a comprehensible manner.

The Disadvantages in the reprocessing or reprocessing of Medical devices, in particular instruments and devices, are transferable on other products that go through a cleaning process. For this belong Products in everyday Use where high processing performance and effectiveness combined with high Economy is required. Disadvantages, which are also still expand because there is no suitable purpose-oriented product arrangement after the reprocessing exists, which means the follow-up costs and this also increases the total costs.

The The invention is therefore based on the object of providing a transportable versatile insert and tray as well as a process for the Preparation and subsequent product presentation develop. In particular, the effective cleaning of product surfaces, products with cavities and with difficult to access Areas guaranteed be inclusive the requirements for documentation, security, validation and product transportation. The tray can also be used in processing machines be introduced as an insert.

This The object is achieved by a portable insert according to claim 1 and by a tray Claim 15 or solved by a method according to claim 18. The dependent claims advantageous embodiment of the invention.

These ricochets have to not just designed as pure surfaces but can be area Rebound structures or other rebound structures such. B. Surveys or contain deformations. Such impact structures in the deflection surface can even preferred in relation to a specific preparation process his. For simplification, the invention speaks of rebound surfaces and not generally of flat Rebound structures or of rebound structures. It is preferred if the invention back and baffles on the front formed. This ricochet is aligned to a treatment source and reflects waves or lets Bouncing off media. You could also throw back or jump back speak. In the case of ultrasound, the sound waves reflect on these surfaces dependent on the sound level. The ricochet also has an influence on the plasma treatment in combination in a vacuum with radio waves. For example, there is the back of the product be at a suitable distance from the inventive rebound surface the treatment waves such as B. ultrasonic waves depending on the angle of incidence (Angle of incidence equal to angle of reflection) reflected back and so the rear surface of the Product. There are no cleaning or treatment shadows, because the reflected waves hit the back wall of the Meet products. About that In addition, the full cleaning power of the waves is used so can also hidden areas of products such as B. cavities of the waves of treatment can be achieved. In the case of light such as B. UV light could the rebound surface reflect the light waves like a mirror.

Already a ricochet can be a treatment room in the direction of a treatment source constrict and the efficiency of treatment with light, ultrasonic waves or microwaves or in a combination of light and ultrasonic waves increase. Such a treatment room can only be changed on one side. In another arrangement, the treatment source can also be arranged spatially be and the waves are spaced apart by baffles this treatment source is reflected. The rebound surfaces can each be smooth or structured after application. It can be an advantage be transparent if the insert or the tray or parts thereof are. The impact force or speed of propagation depends on the type of media used. This is for ultrasonic waves in the presence of aqueous Media favors.

The cleaning power of the medium is improved by using these shafts. The rebound surfaces support the product treatment processes e.g. B. in the form of increased ultrasound massage by targeted throwing back or reflecting the waves. The number of vacuum bubbles is increased. In other words, the cavitation is improved. These bubbles implode in a fraction of a second and generate a high level of cleaning power, especially on the product surfaces. There is better utilization by specifically reflecting the waves towards the product. When ver Using transparent inserts, chemical reactions can be initiated by light. Alternatively, mirror surfaces increase the killing of germs, bacteria or cells, especially in the rear wall areas of a product, or improve the disinfection performance of medium in a treatment bath by reflecting UV waves.

In a preferred method can be the ultrasound treatment with a Pretreatment can be combined with a medium flow. The medium will here in the treatment room z. B. an ultrasound device introduced for pre-cleaning or post-cleaning of the products or exchanged. The tray forms the rebound surface for this Treatment media. Temperature control and a defined medium flow or medium treatment a validable treatment with simple means. Through high temperatures of the medium promotes drying of the tray. Alternatively, here compressed air is also used for drying after the ultrasound treatment become.

at the application by low pressure plasma and an excitation, for example, via radio frequencies can the rebound surface radical formation favorable influence. Light energy could also be used for radical formation become. The product preparation is furthermore traceable Positioning on the inventive tray supports. Without Repackaging the products can be followed by further processing like z. B. sterilization with subsequent transport to the customer respectively. A product damage is avoided. There is no need to reorder the products.

In a general embodiment the materials of the tablet have a simple chemical, physical surface modification or mechanically modified surface structuring. The surface modifications can be used around surfaces easier to clean.
