Applicant claims priority under 35 U.S.C. §119 of German Patent Application No. 10 2006 060 176.9, filed on Dec. 18, 2006, the contents of which are incorporated herein by reference thereto.
The present invention pertains to a marking device for a storage and/or transport container for medical equipment.
It is known from the prior art to accommodate medical devices for and/or after sterilization for storage and/or transport in a storage and/or transport container. Marking of the container and/or the medical devices is then desirable in order to permit tracing.
It is known from the prior art to automatically identify (radio identification) and localize objects by radio frequency identification or RFID.
An RFID system then includes a transponder, also referred to as an RFID label, smart tag, smart label, snifter chip, RFID chip, RFID tag or radio label, read device with corresponding antenna and is integrated in a server, services or other systems, for example, point of sale systems or product inventory systems.
The transponder stores data that can be read without contact and without visual contact, depending on the design (passive/active, i.e., with a power supply via radio waves/with power supply by an integrated power source), employed frequency band, transmission power and environmental effects, to distances between a few centimeters and more than a kilometer. Data transmission between the transponder and reader occurs by means of electromagnetic waves. At low frequencies this occurs inductively via a near field, at high frequencies via an electromagnetic far field.
The basic structure and function of RFID tags is disclosed for example in U.S. Pat. Nos. 4,075,632, 4,360,801, 4,390,880, 4,739,328 and 5,030,807.
It is known from US 2006/0145871 A1 to identify sterilized medical devices situated within a sealed sterilization container before a surgical intervention. For this purpose an RFID tag is connected to each medical device and communicates information concerning the corresponding medical device via radio frequency to a RFID tag reader, which is situated outside of the sealed sterilization container consisting of a material that transmits electromagnetic energy, for example, radio frequency signals. Without opening the sealed sterilization container a user can thus obtain information concerning the contents of a sterilization container.
US 2006/0109105 A1 also discloses a transport container for medical devices in which each transport container has an RFID transponder tag and a barcode. The barcode contains information on the point of origin, the destination and optionally the content of the transport container, i.e., the identification number of each medical device contained in the transport container, whereas each set of medical devices contained in the transport container has an RFID tag. The RFID tag can contain information on the manufacturer, part number, series number and manufacturing date, use and storage and the like.
However, incorporation of RFID tags in each individual medical device is costly and in particular each new medical device must be equipped with an integrated RFID tag or retrofitting of RFID tags in already existing equipment is necessary.
In addition, there is interest in knowing the contents of the storage and/or transport container, optionally also its origin and/or destination, as well as the date of sterilization (since the medical devices only remain sterile for a predetermined time after sterilization) and/or external influences to which the storage and/or transport container was exposed.
One object of the present invention is therefore to design a marking device for a storage and/or transport container, by means of which simple, reliable and easy-to-read marking and tracing are possible.
According to the invention, this task is solved by a marking device for a storage and/or transport container for medical devices which comprises the features of claim 1, namely (a) a mat made of a sterilizable material; and (b) a marking element for storage of electronic information on characteristic parameters of medical devices stored and/or transported in the storage and transport container, which can be read out in wireless fashion. Advantageous modifications of the invention are mentioned in the dependent claims. An RFID tag can be used, for example, as the marking element, in which information concerning sterilization processes, sterilization time and/or other parameters characteristic for the medical devices accommodated in the storage and/or transport container is stored.
In this way the user can acquire, without significant expense, information concerning the content and history of a storage and/or transport container without having to open the container and is thus able to maintain sterility and track the storage and/or transport container.
These and other objects and advantages of the invention will more fully appear from the following description, made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
The present invention will be described in detail below by means of practical examples of a marking device according to the invention for a storage and/or transport container.
A marking device according to the invention for introduction into a storage and/or transport container is shown in
In a preferred modification of the marking device the mat 2 has spacers 3 on its side facing the inside surface of the storage and/or transport container, which can be formed, for example, as small knobs, as shown in
In this practical example according to
A marking element 4 is formed on the mat 2 preferably on the bottom, which contains electronic information, for example, concerning sterilization processes, sterilization time and/or other parameters characteristic for the medical devices accommodated in the storage and/or transport container. The marking element 4 can be glued to the bottom of the mat or connected to it in some other way. As an alternative the marking element 4 can also be integrated in mat 2.
The marking element 4 can also additionally have a marking field 4′, which is advantageously formed on the top of mat 2 and contains information directly readable for the user, for example, a series number. Preferably an RFID tag is used as a component of the marking element 4 for electronic storage of information, whose information can be read out without contact via a reading device (not shown). Both an active and passive RFID tag can be used whose properties were already discussed above, in which the passive RFID tag can be designed smaller because of the absence of a requirement for a power supply. As an alternative, another electronic component can be used as long as it permits storage of data and can be read out in wireless fashion.
In a modification of the invention the marking element 4 additionally has a device for recording and/or storing a temperature trend to which the storage and/or transport container including the medical devices contained in it was exposed. In this way, prior to use of the medical devices stored and/or transported in the storage/transport container it can now be reliably recognized whether the medical devices were exposed to influences and/or an unduly long period has elapsed, due to which sterilization is no longer reliably ensured.
A modification of the present invention is shown in
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of the invention which comprises the matter shown and described herein and set forth in the appended claims.
