Abstract

The present invention relates to a medical-technical identification device for identifying a sterile product (4, 62, 72, 82), and to a method of identifying such a product, for example a product intended for one-time-use only, when connected to a piece of medical equipment (1, 60, 70, 80), wherein the sterile product (4, 62, 72, 82) includes a fixedly mounted information carrier (9, 63, 73, 83) which is adapted to deliver or to offer specific product information in a contactless fashion to a reading element (12, 64, 74, 84) connected to the equipment (1, 60, 70, 80).

Claims

1. A medical-technical identification device for identifying a sterile product that is intended for a one-time-use only, when connected to a piece of medical equipment, the identification device comprising:

a holder fixedly connected to the sterile product, the holder including a first oblique slide surface, as seen in the direction in which the sterile product is mounted,

an information carrier fixedly attached to the holder, which is adapted to deliver, or to offer specific product information in a contactless fashion,

a seat fixedly mounted on the piece of medical equipment, the seat including a second oblique slide surface, as seen in the direction in which the sterile product is mounted,

a reading element that is connected to the seat and to a registering unit which, in turn, is connected to both a storage unit and an analysing unit,

the information carrier being mounted in a fixed relation to the first oblique slide surface wherein the first oblique slide surface and the second oblique slide surface are angled so that when the holder is fitted within the seat, the first oblique slide surface and the second oblique slide surface are brought directly together, placing the information carrier and the reading element into contactless alignment with one another,

the sterile product being a sterile elastic hose part, a sterile saw blade, a sterile drill bit, or a sterile shaver blade,

the analysing unit functioning to deliver signals to an equipment actuating control unit,

the device further comprising a presentation unit which functions to present information from both the analysing unit and the storage unit, and

a programming unit connected to the analysing unit or the storage unit, wherein bringing the information carrier and the reading element into contactless alignment with one another enables identifying of the sterile product.

2. An identification device according to claim 1, characterised in that the information carrier is mounted in or on one side of a holder and in that the reading element is mounted in or on one side of the fixation seat, wherein the exchange of information between the information carrier and the reading element does not take place until the holder is in place in the seat, until connection of the hose part to the equipment has been completed.

3. An identification device according to claim 2, characterised in that the information carrier and the reading element are adapted to take fixed positions relative to one another when the hose part is connected actively to said equipment.

4. An identification device according to claim 3, characterised in that the holder of the information carrier includes a planar slide surface which is angled such that the normal to said surface will not extend parallel with the symmetry axis of said hose part and in that said slide surface conforms to or fits with a correspondingly directed slide surface in the seat.

5. An identification device according to claim 4, characterised in that both slide surfaces are directed so that an applied force intended to press the surfaces together will cause the information carrier and the reading element to be aligned mutually in the direction of an X-axis and Y-axis.

6. An identification device according to claim 5, characterised in that both slide surfaces are directed so that the information carrier and the reading element will also be mutually aligned in the direction of an Z-axis.

7. An identification device according to claim 1, characterised in that the transmission of information between the information carrier and the reading element is caused to take place with the aid of one or more of the following devices:

bar codes, Blue Tooth, radio waves, light waves, infrared light, electromagnetism, radioactivity or chemical transmission.

8. A device for identifying a sterile product that is intended for a one-time-use only, when the sterile product is connected to a piece of medical equipment, the device comprising:

a reading element for receiving or reading product information for products connected to the piece of medical equipment,

an information carrier mounted in a fixed relation to a first oblique slide surface, as seen in the direction in which the sterile product is mounted, of the sterile product and adapted to deliver, or to offer specific product information in a contactless fashion to the reading element, and

a seat, configured to receive the information carrier, fixedly mounted on the piece of medical equipment, the seat including the reading element and a second oblique slide surface, as seen in the direction in which the sterile product is mounted, with which the first oblique slide surface co-acts directly when the sterile product is connected to the piece of medical equipment, the second oblique slide surface corresponding to the first oblique slide surface so as to bring the information carrier and the reading element into contactless alignment with one another, wherein bringing the information carrier and the reading element into contactless alignment with one another enables identifying of the sterile product.
