Definitions

  • Apparatus and method for determining the position of a vein or artery Apparatus and method for determining the position of a vein or artery.
  • the present invention relates to an apparatus for determining the position of a vein or artery in a member of a living being, according to the preamble of claim 1.
  • Vessel puncture is a common procedure in daily hospital/health care practice for e.g. blood withdrawal, catheter placement or to administer medicine and fluids. Normally, superficial veins and arteries are visible and easy to access. However, in a significant percentage of patients (up to 20%) the vessels are not visible and the technician or nurse has to rely on indirect signs like tactile feedback, pressure, pulsation or experience. This results in a relative high failure rate to access the vessel at the first and even secondary puncture attempts. This is a painful experience for the patient and inefficient for the procedure.
  • US 2004/0171923 Al describes a magnifying glass to obtain details of the related member.
  • this can be replaced by an infrared sensor and associated liquid crystal display. These are incorporated in a single housing wherein the line of sight onto the surface of the display is in the extension with the observation line of the infrared sensor. I.e. this alternative embodiment is used in the same way as the magnifying glass.
  • WO 2007/016048 shows an observation system for an animal wherein a camera is provided with a filter to highlight some aspects of the related animal.
  • a monitor is positioned in another location and connected through a cable of the like with the camera.
  • US 6 424 858 discloses a box in which a member can be entered. In the box a camera is provided being connected to an external monitor. The camera can be moved to the optimum position.
  • Transferring light through a member of a living being, or trans-illumination is for example known from WO 96/36273.
  • it is proposed to trans- illuminate the related member with a light source.
  • the observer is provided with a helmet having a telescope device using a filter and further night vision techniques.
  • US 6178340 a method for three dimensional infrared imaging of a part of member of a human being on base of reflectance is used. In other words camera and light source are used on the same side of the member to be observed and this results in the impossibility to observe arteries or veins which are somewhat deeper in the related member.
  • the present invention aims to provide a relatively simple apparatus which is easy to use, cheap to produce and improves the procedure of vessel puncture. However the apparatus could also be used for non diagnostic and non therapeutic purposes. This aim is realized with an apparatus having the features of claim 1.
  • a display is used being spaced from the observer.
  • the related member and display are about the same distance from the eyes of the observer with regard to focusing of the eyes of the observer. This means that in one glance the observer can both observe the related member and the display.
  • the observer can from a single position observe the related position both through the display and through direct observation, i.e. without camera and display.
  • additional certainty is obtained for the observer for example for entering a syringe in a vessel. In this way accuracy is improved.
  • this angle is between 35 and 145°.
  • the light source can comprise an IR led preferably provided with a strap for connecting to the finger or hand of the observer or patient in order to manipulate it in the correct position relative to the member to be observed.
  • the camera can comprise any camera such as a usual CCD camera.
  • the display can comprise any display such as an LCD display. According to a preferred embodiment of the invention the display is fixedly connected to the camera in the position of use. However it might also be possible to allow relative movement of the camera and display. According to a preferred embodiment this can only be effected in one direction. For example the camera can be displaced in a plane being in a range between +25° - -25° to a plane perpendicular to the surface of the display.
  • More preferable display and camera can be freely manipulated together and to that end they are mounted on the extremity of a swivel arm. After placing the related member in the desired position the combination camera and display can be moved together such as to obtain an optimum image of the member and more particular the arteries and veins thereof. If the required position is reached the observer can take the related measure for example puncturing the artery or vein. More preferable the swivel arm together with camera, display and other auxiliaries is weight balanced i.e. is stable in any position in which it is placed. This means that the observer manipulates the combination of camera and display to the desired position with one hand whilst preferably the other hand is used to manipulate the light source.
  • the light source is present in a support on which the member such as a hand is laid or connected to the patient. After correctly positioning of the camera/display the observer no longer engages the swivel arm and can use his hand to operate a syringe or other means for treating the related extremity.
  • the camera or the centre axis thereof is, in the position of use, at the same distance or nearer to the observer than the surface (or part thereof) of the display.
  • the apparatus according to the invention can be used for example with incubators wherein display and camera can be kept outside the incubator in which a child is present.
  • a control grip is provided for engagement by the hand of the observer. If any operating means such as adjusting means for focusing of the camera or controlling the intensity of the light emerging from the infra red source, such control means can be provided on the grip and controlled by a single hand.
  • the swivel arm is embodied such that the mounting of the camera and display will always have the same orientation (preferably vertical) irrespective of the position of the swivel arm.
  • This can for example be effected by constructing the swivel arm from a number of sub-arms producing a parallelogram structure. In this way parallax can be further avoided.
  • the invention also relates to a method for determining the position of a vein or artery in a member of a living being by an observer, comprising trans-illumination of said member with an IR light beam from one side of said member to the other side thereof, scanning said opposite side of said member with an IR sensitive camera and producing a visible image of said camera scanned area, wherein producing of a visible image comprises showing said image on a display spaced at least 30 cm (b) from the eyes of the observer. Determining this position can be both for therapeutic/diagnostic reasons and for other reasons.
  • the position of the observer, display and vein or artery in said member is such that the line of sight of the observer to the display substantially corresponds to the line of sight of the observer to said vein or artery.

Abstract

La présente invention concerne un appareil et un procédé pour déterminer la position d’une veine ou d’une artère dans un membre d’un être vivant. Avec une source lumineuse IR, plus particulièrement une source lumineuse LED IR, le membre en question tel qu’une extrémité et plus particulièrement une main, est éclairé transversalement. La lumière IR sortant du membre est analysée avec une caméra et l’image est générée sur un écran adjacent à la caméra. La caméra et l’écran sont de préférence montés sur un bras manœuvrable qui peut être placé dans une position souhaitée quelconque par rapport au membre et à l’observateur. Le déplacement de l’unité caméra/écran peut être effectué grâce à la présence d’une poignée actionnée par la main de l’observateur. Si la position de repos est trouvée par rapport au membre, la main de l'observateur peut être utilisée pour exécuter le traitement associé de la veine ou de l’artère.
