Definitions

  • the present utility model refers to a wireless portable oximeter, i.e. a device that measures the oxygen saturation and heart rate of a patient non-invasively, comprising a unit for installation in the patient's finger .
  • Oximeters are already known comprising a unit that fits the patient's finger, which is provided with oxygenation sensors of the blood and heart rate.
  • One such device which is described in patent document BR 10 2015 028372 5 entitled “Pulse Oximeter Wireless for continuous use '' discloses in its Fig. 1, a unit 10 in the form of clamp for installation in finger of the patient.
  • Another object is to provide retention means which are easy to apply and remove.
  • Another object is to ensure the repeatability of the fixation regardless of the skill of the operator, while ensuring that the pressure exerted on the finger is that specified by the oximeter manufacturer.
  • a constructive arrangement of its two-part housing forming a gripper comprising first and second parts, configured so as to fit the patient's finger when closed, in order to enclose the its end, said first part being provided, at its proximal end, with a half-cane-shaped extension dimensioned to fit the finger.
  • the attachment of the oximeter to the patient's finger is provided by the juxtaposition of said extension to the finger and by a strap having semipermanent retention means, surrounding the finger with the extension thereto juxtaposed .
  • the oximeter comprises at least one spring attaching the first and second portions of its housing, which presses said parts against each other providing the closure of said housing over the of the patient, without, however, collaborating to the retention of the oximeter.
  • Figure 1 is a perspective view of the oximeter affixed to the patient's finger.
  • Figure 2 is a side elevational view showing the position of the finger within the oximeter.
  • Figure 3 shows the position of the spring with respect to the two-part housing.
  • FIG. 1 shows the oximeter 11, which housing comprises a first portion 13 and a second portion 14, the patient's finger 12 enclosing therebetween by mutual compression between said portions.
  • the figure further shows the approximate half-cane extension 15 provided at the proximal end of said first portion, with dimensions that provide for its adaptation to the finger.
  • the fixation of the oximeter is provided by a strap 16 provided with retaining means, which surrounds the patient's finger 12 together with said extension 15 which is juxtaposed thereon.
  • Said retention means are selected from the group comprising an adhesive, a push button or a Velcro fastener.
  • FIG. 2 is a simplified elevational view where the position of the finger 12 is shown in dashed line within the oxymeter 1 where, for clarity, the oxygenation sensors of the blood and the heart beat are not shown .
  • the retention of the oximeter 11 to the patient's finger 12 is provided exclusively by the compression of the strap 16 which envelops therein both the finger 12 and the extension 15 of the first part 13 of the housing, the dimensions and curvature allow you to adjust your concavity to the convexity of the finger.
  • the illustrated arrangement makes it possible to separate the retention functionality and the one relating to the pressure of the clamp effect exerted on the finger.
  • FIG 3 shows, in simplified view, one of the springs 17 which, in addition to attaching the first part 13 and the second part 14 of the housing, exerts a force 18 which presses said parts against each other, providing the closure of said envelope on the patient's finger, without, however, collaborating for the retention of the oximeter.
  • the pressure exerted on the patient's finger no longer depends on the skill level of the operator. Both the possibility of excessive pressure, which would tend to impair circulation, and an insufficient pressure that could result in errors in reading the physiological conditions monitored by the oximeter sensors 11 are avoided.
  • the springs 17, the characteristics of which are determined during manufacture of the oximeter by the manufacturer, ensure that the pressure maintains a uniform and predetermined value irrespective of the time in which the device is installed in the patient and the operator's ability, ensuring the uniformity of measurements and the reliability of the results.

Abstract

L'invention concerne un agencement structural destiné à un oxymètre portatif pour utilisation en continu, comprenant une enveloppe en deux parties (11) formant pince constituée par une première partie (13) et une seconde partie (14) conçues pour serrer entre elles l'extrémité du doigt (12) du patient en position fermée, ladite fixation étant assurée par superposition, sur ledit doigt (12), d'une extension (15) en forme de demi-tige pourvue au niveau de l'extrémité proximale de ladite première partie (13), et par une bande (16) dotée de moyens semi-permanents de retenue entourant le doigt (12) conjointement avec ladite extension (15), la pression (18) de fermeture entre lesdites première partie (13) et seconde partie (14) de l'enveloppe étant produite par des ressorts (17) reliant lesdites première et seconde parties entre elles.
