Definitions
- the present invention relates to a gauze for surgical use, the presence of which is remotely detectable.
- Multi-web gauzes made of hydrophilic warp and weft tissue, for example cotton, are known to be normally used in the surgical field for temporarily tamponing any loss of blood or fluids from a patients being subjected to an operation.
- the object of the present invention is to provide a gauze or other material for surgical use which can be remotely detected, is cost- effective and simple to manufacture. SUMMARY OF THE INVENTION It is therefore an object of the present invention to meet such requirements by providing a gauze or other material for surgical use, wherein at least one presence detection device is comprised for remotely identifying said gauze or said other surgical material.
- said detection device is capable of changing the intensity of a magnetic field, in which it may be immersed. Furthermore, said detection device can be thread-like and interlaced in the warp or weft of said gauze.
- Fig. 1 is a view of the gauze according to a first embodiment
- - Fig. 2 is a view of the gauze in accordance with a second embodiment of the present invention.
- the gauze according to the invention has been generally designated with 1 .
- the gauze 1 is made of warp and weft hydrophilic tissue, such as cotton, and is provided with webs 2 having a substantially rectangular shape. It should be also observed that said gauze 1 can further comprise a radiopaque thread-like element 3 arranged in the warp and/or weft of the hydrophilic tissue, which is capable of allowing said gauze 1 to be detected through a radiographic examination.
- said gauze 1 comprises a presence detection device 4 in a substantially rectangular shape, which is fastened, for example by bonding, to the upper surface 7 of said gauze 1 or between said webs 2 or inserted within a suitable housing pocket (not shown) obtained on said gauze 1.
- said detection device 4 can be provided with gripping elements (not shown) that can be inserted between the meshes of the warp and weft of said webs 2 thus fastening to said gauze 1.
- Said detection device 4 is provided with an integrated electronic circuit 5 (CHIP) and a communication antenna 6 that is capable of receiving and/or transmitting any information in case processed by said electronic circuit 5.
- CHIP integrated electronic circuit
- said detection device 4 is subjected to a specific external radio frequency signal, it is activated and transmits, in turn, ⁇ specific signal to the emitting source of the radio frequency signal.
- Said detection device 4 can further comprise a memory element 10 capable of containing further information, such as the identification number or type or sterility life of the gauze, or other useful information for the medical or paramedical staff either before, during or after the surgical operation.
- a memory element 10 capable of containing further information, such as the identification number or type or sterility life of the gauze, or other useful information for the medical or paramedical staff either before, during or after the surgical operation.
- said detection device 4 is substantially thread-like and is inserted in the warp and/or weft of said gauze 1.
- Said detection device 4 is made of a material capable of changing the intensity of a magnetic field to which it is subjected, such as, magnetizable or magnetically active metal.
- Said gauze 1 in the event it is inadvertedly left in the patient's body during the surgical operation, can be easily identified by means of an external device for signal generation and reception (not shown herein).
- Said signal-generating and receiving device is placed at a certain distance from the patient undergoing a surgical operation and generates a signal that is recognized by the detection device 4 constrained to said gauze 1 , for example of the radio frequency type, as in the first embodiment of the gauze 1 , or magnetic type, as in the second embodiment of the gauze 1. Subsequently, this signal- generating and receiving device is capable of receiving a feedback signal from said detection device 4 indicative of the presence of said gauze 1, provided that the latter is within the working range of said signal-generating and receiving device. Said detection devices 4 also operate in the most serious cases, i.e. when said gauze 1 is left in the patient's body even after the surgical operation, in fact said radio or magnetic signal that are generated and received by the detection device and signal-generating and receiving device are capable of passing through the tissues in the human body without being affected by substantial interferences.
