Description

The The invention relates to a device for storage, sterilization and / or cleaning and providing for the use of medical Instruments.

Currently There are various storage baskets and sieve pads that either exclusively for the Storage and / or sterilization of medical instruments, especially micro-instruments. The cleaning takes place in a separate process by removing the instruments from or from these baskets / pads taken down in ultrasonic cleaners or thermal disinfectors be placed and positioned.

All Cavity instruments, these are medical instruments that have a Cavity, for example. A tubular Lead, ent, must be dealt with separately by referring to special adapters in the Thermodisinfectors are connected. Or they will be in one manual process by means of cleaning pistol or large volume Syringe treated and cleaned.

Then be all instruments once again for sterilization in the sterilization boxes positioned.

To sterilization is carried out a further repositioning on the sterile Instrumentation table, so that the instruments, e.g. be used for an operation can.

These Overall, processes are less standardized, relatively confusing, offer a variety of possible errors and promote that Wear the Instruments.

Especially in ophthalmic surgery finds a number of very standardized microsurgical procedures in and on the eye.

All used instruments are characterized by their low Allowances Fineness and accuracy but especially its sensitivity across from mechanical and chemical influences.

One particular problem is the need to work with fine cannulas and suction / rinsing systems in the eye.

regardless whose can and allowed only correct and complete cleaned and then sterilized Instruments are used.

Especially the findings of possibility the transmission diseases due to protein deposits on used instruments, have too far-reaching new requirements regarding one mechanical cleaning of the instruments.

So the demand is for implementation, all for reuse Instruments alkaline in a validated machine process to clean.

These Requirements already have a very structured way of working and led to the development of instrumentation screen sizes.

crux However, these screen covers have always been safe and structured Operation on the operating table during instrumentation.

With The automatic reprocessing of these instruments is now emerging new challenges.

The Handling the instruments must be the system of thermal disinfectors be adjusted. In particular, the preparation of the cannulas and suction / irrigation systems currently require a considerable additional expenditure of time and also on handles. The clarity and systematic is lost through these many manipulations, and new sources of error arise. In particular the demand for alkaline Cleaning (cleaner with a PH value of 9 to 11) brings in one barely reproducible manual cleaning process new dangers for the to be operated patients. These alkaline cleaners require after neutralization after the cleaning process, the PH value must be adjusted accordingly. If that does not happen, it almost happens inevitably at a risk for the patient, which is many times higher and very short term irreparable damage to lead can.

Accordingly hardly leads a way past the machine cleaning in which the required to make chemical processes reproducible and safe in the Result in creating a validated procedure.

The invention is therefore intended to provide a combined Instrumentensiebauflagen for medical instruments, in particular for microsurgery, which is suitable for a continuous process of gentle cleaning, sterilization, storage and instrumentation of such medical instruments, in particular micro and Holrauminstrumente. In particular, it should be ensured that each of a plurality of medical cavity instruments connected in the device for cleaning is verifiable nigt and / or sterilized.

These Task is solved through a device for storage, sterilization and provision for the use of medical Instruments with the features of the protection claim 1. Advantageous Further developments of the invention are in the dependent claims 2 to 11 closer characterized.

According to the invention the device comprises a frame and a screen support held in the frame on. On the frame are flushing pipes (at least two), each individually and separately from one another Connection connection with a sterilization or disinfection device and over a rinse connection to connect a medical cavity instrument for connecting the cavity have the same with the sterilization or disinfection device.

By this embodiment can in the device according to the invention "normal" medical instruments placed on the screen in an orderly manner, while on the Rinse pipes Cavity instruments at the Spülanschlüssen also ordered can be determined. With one and the same device, the orderly filed Instruments are disinfected (for the "normal" instruments in a corresponding bath, for the Cavity instruments by connecting the connecting terminals of used rinsing pipes with a sterilization or disinfection device, for example a thermodisinfector). After disinfection or sterilization, the Instruments in the orderly filed manner on the device and either storage or instrumentation for the Use during an OP supplied become.

Of the The essential advantage of the invention lies in the possibility of a connection the cleaning and sterilization of medical instruments, in particular microsurgical and holraum instruments on one Platform in a continuous machine process that can be validated and thus the new more extensive legal hygiene requirements equivalent. It is essential that the rinse pipes individually and separately each with a cavity instrument and with the disinfection or Sterilization device can be connected. That is the only way to be sure be that a failure of a pipe, for example, by an obstruction, detected and a faulty cleaning / disinfection of a medical Instrument recognized and sorted out the instrument concerned and can be cleaned. Monitoring the correct treatment an instrument can, for example, by measuring the flow in one to one of the rinse pipes leading Conducted. Is a measurable flow missing or is such too low, a mistake can be detected and a specific instrument be assigned.

On the other side allows the invention a gentle and cost-conscious operation with the instruments while creating a very systematic Operation. Each instrument retains during the subprocesses Cleaning, sterilization, storage and transport through to instrumentation always the same place on the operating table. Unnecessary handling is eliminated as well like unsafe storage. This will be the largest part of the known sources for damage the instruments, but also an unwanted contamination of the same locked out. The created system also allows a secure control of the Care and cleaning state of the instruments.

In According to an advantageous development of the flushing connections are in two different parallel to the level of Siebauflage located levels. This can do more stored medical instruments in the device according to the invention or be stored by dividing into different positions also possible in a third dimension.

there is of particular advantage when provided as in claim 3 a the levels with flushing connections above and another level below the level of Siebauflage lie. In this way, then a total of three levels of storage for instruments created, the overall more space for an orderly arrangement the instruments to be deposited or stored in the device results.

A further advantageous embodiment of the invention is claimed 4 indicated. Accordingly, the flushing connections in the different levels arranged on different sides of the frame. There are several Spülanschlüssen within one level of these all preferably on one and the same side, the flushing connections in the second level all on a different side of the frame from the first page of the frame. This too leads as a result, the possibility within the device according to the invention very orderly to attach a variety of instruments clearly arranged.

Another contribution to an ordered arrangement or storage of medical instruments in the device according to the invention is achieved by a preferred embodiment, as indicated in claim 5. This means:
As a result of the different levels already separated by instrument type, common specify economic storage locations within the device.

Especially for longer flushing pipes it is advantageous if these, as described in claim 6, in the device in use position in the direction of her Connection terminals are inclined. Such a tendency namely a drain of residual disinfecting or cleaning fluid from the rinsing pipes sure, so that non-residual fluid will undergo a later disinfecting or cleaning process obstruct or even undermine.

Prefers the device is particularly preferred, at least with the rinsing tubes also with and the connection and flushing connections as well as the sieve support, formed of metal (claim 7). This material can be on the one hand, easy to process the shape of the invention, he is also suitable for the different processes of sterilization / disinfection, Survive storage and instrumentation without damage. Of course you can Other materials are used, such as different Plastics or the like. The choice of material will be apparent to those skilled in the art the specific application, taking into account the production costs make.

Feet, like they are the device in a specified in claim 8 advantageous Further education may serve to the device in disinfection / sterilization containers or at the storage location or in the area of an operating table to be able to.

Handle elements, as they according to a advantageous development are provided according to claim 9 serve a simplified handling of the device, in particular under Reducing the risk of contamination in the device stored medical instruments.

The according to a specified further advantageous development (claim 10), preferably made of silicone, settable in the screen support Instrument holders allow for a fixation of in the device deposited on the screen support, the others an individual arrangement of them as needed. So can in particular an operating team working with the instruments yourself one for the own requirements suitable arrangement of the instruments set up the screen pad, which then retained for further procedures can be.

At a rinsing pipe arranged clamping elements provide another means to medical Determine instruments or their parts in the device (see. Claim 11). For example. may be a connection or the like in the end a hose to be cleaned and disinfected from the inside too be fixed in on such a clamping element.

Further Features and advantages of the invention will become apparent from the following Description of an embodiment with the attached Characters. Showing:

1 a plan view of an embodiment of a device according to the invention;

2 a view of the embodiment of the in 1 on the right side; and

3 a view of the embodiment of the in 1 below shown longitudinal side.

In The figures are the same elements with the same reference numerals. The figures are schematic representations and in particular not to scale.

In the figures, an inventive device for storage, sterilization and providing for the use of medical instruments is generally with 1 designated. The device according to the invention 1 contains a frame 2 , In the frame 2 is within its level a screen pad 3 arranged. This consists essentially of one in the frame 2 clamped mesh 4 which is in the 1 is shown only in the upper left corner, but extends within the entire frame.

At the frame 2 are rinse pipes 5 and 6 set, each via a connection port 7 for connection to a thermal disinfector. They also have flushing connections 8th respectively. 9 that (cf. 2 and 3 ) in a plane below the through the screen pad 3 level formed (Spülanschlüsse 8th ) or in a plane above the latter level (Spülanschlüsse 9 ) lie. The rinsing pipes 5 . 6 lie on a common end face of the device 1 on the frame 2 firm and have their connection connections 7 at this end face in a common plane (one level below the plane of the screen pad 3 ). The rinsing pipes 6 are below the sieve pad 3 along to the opposite end of the device 1 guided and there with their Spülanschlüssen 9 in a plane above the level of the sieve pad 3 bent. The rinsing pipes 6 run in their below the level of Siebauflage 3 guided region inclined with respect to a horizontal (considered in a position of use of the device, as in 3 is clearly visible). This passion is chosen so that the connection connection 7 at the lowest point of the flushing pipe 6 lies. This tendency has the purpose that after a cleaning or sterilization run the cleaning or

Sterilization fluid almost residue-free from the rinsing tubes 6 can expire. Thus it can be prevented that residual fluid remaining in a subsequent cleaning or sterilization run in the flushing tube cools the fresh cleaning or sterilizing fluid as condensate formed during heating and thus a required sterilization temperature, for example when using saturated steam as the sterilizing fluid currently 134 ° C. , is undershot. For the same reason, even the shorter rinse pipes 5 run correspondingly inclined.

The device 1 has feet on both its underside and top 10 on, for placing the device on straight documents, possibly also "overhead" 10 have a standing height, which is dimensioned so that the below or above the level of the screen support 3 lying flushing connections 8th respectively. 9 on on the feet 10 shut off device 1 are floating freely. Below the level of the sieve pad 3 are only on one end of the device 1 two feet 10 arranged on the opposite end face is the device 1 on an extension 12 of the frame 3 , on which also the rinsing pipes 5 . 6 are fixed. An arrangement of feet 10 both at the bottom and top of the device 1 serves to turn the device especially for the removal of on the bottom (on the rinsing tubes 5) set, sterile medical instruments turn off and defined, without the risk of contaminating the instruments located on the top of the device or even to to damage.

The feet 10 are on the frame 2 the sieve pad 3 established.

Also fixed to the frame are grab handles 11 located at the front ends of the device 1 above the level of the sieve support 3 are located.

The device 1 In this exemplary embodiment, furthermore, silicone holding elements (not illustrated here), which are provided with a corresponding fixing device in the mesh braid 4 the sieve pad 3 can be set positionable. These serve to fix the position of medical instruments that are not cavity instruments.

In use is the device 1 versatile use. In particular, instruments arranged therein may be placed on the screen pad 3 discarded "normal" medical instruments as well as at the flushing outlets 8th respectively. 9 fixed cavity instruments are disinfected or sterilized in a predetermined arrangement on this device. For this purpose, the device can be set in total in a sterilization bath, and the connection terminals 7 the rinsing pipes 5 . 6 can be connected to a thermodisinfector. Disinfecting fluid exiting the thermodisinfector then flows through the flushing tubes 5 . 6 and via the flushing connections 8th respectively. 9 into the cavity instruments connected to these flushing ports.

After disinfection, the device can 1 on the handles 11 collected and stored in their entirety, ie with the medical instruments placed on them or attached to irrigation ports, or instrumented for re-use in the surgical area.

Out the above description of the embodiment it follows that the device according to the invention a considerable Further development in the field of storage, sterilization and Providing medical instruments.
