Definitions

  • This invention refers to an oral support for imaging devices, which provides stability and control of tip pressure applied to the sublingual region for the study of blood microcirculation.
  • This invention comprises means of stabilizing and supporting the equipment such as a sublingual microcirculation imaging microscope.
  • the oral support of this invention comprises a transparent disposable tip, with thread, which covers the optical tip of the microscope image capture micro scan, as well as an oral threaded support to be positioned in the mouth of the patient, and this support has an inclined threaded seat, capable of receiving the transparent tip adjustable in its depth, allowing the reading of the blood microcirculation in the sublingual region without it being pressed by the disposable cap of the optical tip, allowing the physician or healthcare provider to operate the equipment and capture the image with a more accurate result and without loss or changes in data, since the device is firmly fixed between the mandible and maxilla of the patient, generating greater stability with the desired contact pressure, for a more accurate reading.
  • This invention also reveals a constructive alternative, consisting of a ring adjustment support, with two independent rotation axes, providing an orbital movement and a greater degree of freedom in regulating the positioning of the transparent tip in the sublingual reading region.
  • imaging equipment for medical treatment, such as, for example, sublingual microcirculatory imaging microscopes applying a force and generating an exacerbated pressure of the tip of the equipment on the tissue of the sublingual region.
  • a serious systemic disease e.g: Sepsis
  • the term 'artifact' refers to results that are not manifestations of the natural phenomena under investigation and can be classified as pressure, lighting, focus, content and focus.
  • HVM Hand-held Vital Microscopes
  • the microscope is sensitive to movement and pressure artifacts, thus, during the handling of this device by the physician on the surface of the sublingual tissue, a change in microcirculatory blood flow may occur, compromising the monitoring data. Once the microcirculation is just below the microscope, excess pressure applied to the area can collapse it, and the investigation becomes unreliable (De Backer 2007). The risk of obtaining biased results is high when one depends on the researcher's ability to handle pressure artifacts.
  • this invention reveals an oral support with transparent threaded tip and a threaded oral support to be positioned in the mouth of the patient, and this support has an inclined threaded seat, which can receive the transparent tip adjustable in its depth, allowing reading the blood microcirculation in the sublingual region, eliminating the known obstacles of the prior art.
  • This invention also includes a constructive alternative, consisting of a ring adjustment support, with two independent rotation axes and threaded inner seat, providing an orbital movement and a greater degree of freedom in regulating the positioning and depth of the transparent tip in the sublingual reading region.
  • a constructive alternative consisting of a ring adjustment support, with two independent rotation axes and threaded inner seat, providing an orbital movement and a greater degree of freedom in regulating the positioning and depth of the transparent tip in the sublingual reading region.
  • the oral support of this invention is more portable, lighter than the known supports, providing the patient and operator with greater comfort in its handling and operation.
  • Another great advantage of this invention lies in the fact that the accuracy in the reading of monitoring data is increased, avoiding data compromise or alteration.
