Description
MARKER FOR SURGICAL PRODUCTS, AS WELL AS APPARATUS AND METHOD FOR ITS DETECTION
The present invention relates to a marker for surgical products, like for example tampons, compresses, gauzes, bandages and the like. The present invention also relates to an apparatus and a method for detecting said marker.
US 3834390 discloses a surgical tampon provided with a marker detectable with X-rays. However, an X-ray apparatus for detecting this marker is expensive and complex to be used and furthermore is not always available in the operating theatre. For overcoming these drawbacks, US 3097649 discloses radioactive markers, US
4114601 and US 4193405 disclose radiofrequency transponders and WO 97/45057 discloses a light and/or acoustic signaling device which can be activated by an electromagnetic field. These known markers are expensive to be manufactured, so that they are not suitable for being applied to disposable surgical products. WO '94/17767 discloses a metallic marker which can be detected by a metal detector, which however may give incorrect signals due to the high number of metallic articles present in an operating theatre.
EP 948940 discloses a magnetic marker and an electromagnetic detector, which are however quite unreliable and relatively expensive. WO 98/10367 discloses a marker with a bar code, which however cannot be correctly detected if it is covered by the corporal fluids of a patient, even if the code is written with a fluid-repellent ink.
It is therefore an object of the present invention to provide a marker which is free from said disadvantages. Said object is achieved with a marker, a surgical product, an apparatus and a method, the main features of which are disclosed in claims 1, 18, 19 and 25, respectively, while other features are disclosed in the remaining claims.
Thanks to the signs opaque to infrared light, the marker according to the present invention is not only inexpensive to be manufactured and reliable in the detection, but can also be detected with a simple and quick method by an apparatus, also simple and inexpensive.
The marker preferably comprises more layers manufactured with particular
materials and/or thicknesses, so as to improve the mechanical resistance and to optimize the reading features of the signs opaque to infrared light. For the latter purpose, the signs are preferably obtained from particular inks, which can also be opaque to X-rays, so as to carry out a double check, if desired. For a greater security and/or privacy, the marker can further comprise one or more layers of ink transparent to infrared light but opaque to visible light, so as to cover the signs opaque to infrared light.
The apparatus according to the present invention preferably works with synchronized pulses, so as to improve the reading precision without excessive electric consumptions. For improving its detection, the marker is preferably arranged between the infrared illuminator and sensor.
Further advantages and features of the marker, the apparatus and the method according to the present invention will become clear to those skilled in the art from the detailed and non-limiting description of some embodiments thereof with reference to the attached drawings, wherein:
- figure 1 shows a top view of a tampon provided with a first embodiment of the marker;
- figure 2 shows an enlarged view of detail II of figure 1 ;
- figure 3 shows an enlarged view of a second embodiment of the marker; - figure 4 shows an enlarged sectioned view of plane IV-IV of figure 3;
- figure 5 shows a schematic view of a first embodiment of the detecting apparatus; and
- figure 6 shows a schematic view of a second embodiment of the detecting apparatus.
Referring to figures 1 to 3, it is seen that the marker according to the first embodiment of the invention comprises in a known way a label 1 suitable for being applied onto a surgical product 2, for example a tampon. More in detail, label 1 is a tape or thread and has one or more signs, for example alphanumerical symbols 3 and/or bars
4, which act as codes and can be detected by an external detecting apparatus.
According to the invention, signs 3 and/or 4 are made of a material opaque to infrared light, in particular to infrared light having a wavelength comprised between 900 and 1000 nm, so that they can be detected by a detecting apparatus provided with an
infrared sensor. Width L of label 1 and width V of signs 3 and/or 4 are preferably comprised between 2 and 10 mm.
Referring to figure 4, it is seen that label 1 comprises a first support layer 5, in particular made of polyester, which is transparent to infrared light and has a thickness comprised between 7 and 50 μm, in particular between 15 and 25 μm. Support layer 5 is preferably transparent also to visible light. A first layer 6 of ink transparent to infrared light and opaque to visible light can be applied on support layer 5. Ink layer 6 has a thickness comprised between 0,5 and 10 μm, in particular between 2,5 and 3,5 μm. Signs 3 and/or 4 opaque to infrared light are in turn applied on ink layer 6. Signs 3 and/or 4 can also be opaque to X-rays and can be obtained from an ink containing metal pigments, in particular aluminum, iron oxides or their alloys, such as for example aluminum and nickel alloys. The ink granulometry is comprised between 0,2 and 20 μm, in particular between 0,2 and 2 μm, while the ink thickness is comprised between 0,5 and 10 μm, in particular between 5 and 10 μm. A first adhesive layer 7, preferably transparent to infrared light, is applied on ink layer 6 already provided with signs 3 and/or 4. A second support layer 5', which is similar to the first support layer 5 and can be provided with a second ink layer 6' similar to the first ink layer 6, is applied on adhesive layer 7, so that signs 3 and/or 4 are sealed between two support layers 5, 5'. The so obtained label 1 can then be overturned and applied by means of a second adhesive layer 8 onto the surgical product 2, as shown in figure 4. In other embodiments, label 1 can be applied to the surgical product in other way, for example my means of seams or even insertion into the same product. Label 1 can be applied at different positions, also external with respect to the surgical product.
Figure 5 shows the detecting apparatus according to a first embodiment, which comprises an infrared light illuminator 9, preferably provided with NIR (Near Infrared) LED diodes, which emit infrared light with a wavelength greater that 650 nm, and an electronic infrared camera 10, which acts as an infrared sensor for detecting signs 3 and/or 4 of label 1. Illuminator 9 and camera 10 are preferably connected to an electronic control unit 11, so that illuminator 9 and camera 10 are activated in a synchronized manner with periodic pulses having a duration comprised between 5 and 20 ms, in particular 10 ms. Label 1 is preferably arranged between illuminator 9 and
catnera 10, so that signs 3 and/or 4 can be detected by camera 10 against the light.
In an alternative embodiment, which is shown in figure 6 and is necessary when the surgical product 2 is not transparent to infrared light, illuminator 9 and camera 10 are arranged on a same side of label 1, so that signs 3 and/or 4 are detected through reflection of the infrared light.
