Description

    RELATED APPLICATIONS
  • This application is related to, and claims priority from U.S. Ser. No. 10/366,021 filed Feb. 13, 2003, and U.S. Ser. No. 11/032,953 filed Jan. 11, 2005, the entirety of which is hereby incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • The present invention relates to an illumination method and device for use during interventional or diagnostic procedures. It further relates to the illumination of intravenous (IV) drip components such as IV medication/solution bags, their drip chambers and tubing during interventional or diagnostic procedures. IV fluids are generally supplied to a patient under the force of gravity by positioning an IV bag containing the IV fluid at an elevated position relative to the patient. The rate of flow is set by a manually adjustable clamp positioned in the line between the IV bag and the patient. The fluid flows to the patient via a drip chamber attached to the lower, or outlet end of the IV bag. The drip chamber generates discrete, successive drops that fall from the drip chamber into a reservoir defined at the lower end of the drip chamber from which the fluid flows to the patient via an IV delivery tube.
  • The IV bag is transparent so that its fluid level may be observed by medical personnel. The drip chamber is also transparent so that the drips may be observed by an anesthesiologist or other medical personnel to ensure that the drippage is occurring and to further ensure that the drippage rate is within the appropriate predetermined limits.
  • It is especially critical that a proper drippage rate be maintained and verified during surgical or diagnostic procedures. However, an increasing number surgical procedures are being performed using fluoroscopy, in a dark room or a room with only ambient lighting since any direct light will compromise the performance of the radiologist or any medical professional, or integrity of the procedure, with resulting risk to the patient. The medical team must be able to clearly view the IV drip chamber and confirm a constant fluid drip is being maintained in order to prevent a life-threatening clot from forming at the tip of a catheter which is utilized throughout the interventional procedure.
  • It is also critical that a proper drippage rate be maintained and verified for patients who require medical infusions of medication around the clock. Often, a patient requires medication every two or four hours. In order to properly administer medication to patients on a 24-hour basis, including during the hours of darkness or in patient rooms that are dark, the healthcare worker must either turn the lights on in the patient's room or use a portable flashlight.
  • The constant disturbing of the patient every two or four hours to administer medication, check the IV drip rate or to check the amount of solution in the Iv bag results in the patient being unable to obtain a necessary period of restful sleep. This lack of uninterrupted sleep results in a recognized psychological disorder referred to as Intensive Care Unit Psychosis. Importantly, the ability of patients to recover from their ailments is endangered because of the deprivation of proper rest.
  • It is therefore an object of the invention to provide a compact and portable device that is able to support IV drip components such as an IV bag, its drip chamber and tubing and provide a localized light source that is accurately directed thereat so that a healthcare professional in an unlit, dimly or normally lit room can easily and accurately determine that drippage is in fact occurring and/or is occurring at the predetermined satisfactory rate. It is especially critical that proper drippage rate be maintained and verified during any medical, surgical or diagnostic procedure.
  • SUMMARY OF THE INVENTION
  • In accordance with the present invention, there is provided a compact and portable device that is able to support IV drip components such as an IV medication/solution bag, its drip chamber and tubing. The device also provides a localized light source that is accurately directed at the IV drip components so that a determination that drippage is in fact occurring and/or is occurring at the predetermined satisfactory rate may be easily and accurately made, even in an unlit, dimly lit or normal ambient lit environment.
  • In its most general form, the device consists of a light containing base portion and an adjustable and removable back portion. The base portion contains a light source that can be powered by internally stored batteries, rechargeable or not, or an external low-voltage power supply or by a combination of batteries and external power source. In one embodiment of the invention, light emitting diodes (LEDs) are used as the light source. Other light sources while being in association the other aspects of the present invention form several embodiments. Examples of such other light sources include, but are not limited to fiber optic lights, phosphorescent lights, fluorescent lights or tungsten containing devices (e.g., light bulbs), etc.
  • The back portion is designed for supporting IV drip components such as an IV medication/solution bag, its drip chamber and tubing. The back portion may be adjustable in order to accommodate IV drip components of different sizes or to accommodate other situations wherein the greater overall height of the IV drip components might be useful.
  • The invention can be used in a wide variety of ambulatory field environments. In one embodiment, the invention may be used as a stand-alone device. That is, it may be attached to a tabletop or any surface or plane by way of a retention means. In another embodiment, the invention may be hung from virtually any conceivable support structure. In yet another embodiment, the invention may be attached to a vertical IV support pole by means of brackets on the back portion.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The present invention is an intravenous illuminator apparatus designed for illuminating an intravenous (IV) drip chamber, IV tubing and medication/solutions bag(s). The apparatus consists of a universal, adjustable, holder bracket for use with a solution/medication bag and IV drip chamber and tubing, and it incorporates a base illuminator assembly or light source that is battery powered (DC) and/or AC powered via the use of a universal power supply/charger.
  • The IV illuminator apparatus according to the present invention also employs attachment brackets that facilitate the use of this device with any standard IV pole. More generally, the apparatus is comprised of a base portion and a detachable back portion. The detachable back portion is designed to hold or support any typical IV solution bag or bottle along with an IV drip chamber and tubing. The inventors envision that the present apparatus may be ganged, or attached together, for use when multiple IV solutions or medications are being dispensed or infused into a patient. The inventors also envision that the invention may be used in desk-top or table-top settings, attached to or located near procedure tables and that it may be attached to any surface, plane, hook, loop, etc by way of a retention means, thereby allowing the apparatus to be used in a wide range of ambulatory field environments.
  • A preferred embodiment of the invention uses light emitting diodes (LEDs) as a light source, though other light sources such as electroluminescent lights might conceivably also be used. The LEDs can be powered by internally stored batteries, rechargeable or not, or by an external low-voltage power supply or by a combination of batteries and external power source or by other suitable methods.
  • FIG. 1A is a perspective view of the front and one side of the single intravenous drip components illumination device 10 according to the present invention, showing the two main components which are a light containing base portion 12 and a moveable back portion 14. FIG. 1B is a perspective view of one side and the rear of the single intravenous drip components illumination device 10 comprised of the base portion 12 and moveable back portion 14. In both FIGURES, a base illuminator assembly 16 on the base portion 12 incorporates a window 18 beneath which (i.e., inside the illuminator 16) is an array of LEDs (not shown). FIG. 1C shows an intravenous drip bag 20 hanging from the hook nib 22 at the top of the moveable back portion 14. The bag 20 is being lit by light rays 24 emanating from the base illuminator assembly 16.
  • FIGS. 1A, 1B and 1C also show the on/off switch 26, electrical input receptacle 28 and, in the partial backside view shown in FIG. 1B, the IV pole support brackets 30 with which the present invention can be attached to a vertical IV support pole (not shown). The presence of the power receptacle 28 is not meant to imply that external power is the only source of energy for the light source in the base illuminator assembly 16;
  • the inventors conceive that batteries, rechargeable or not, can be incorporated within the base portion 12 and used with or without the benefit of a source of electrical energy that is external to the invention. FIG. 1B also shows a large hook ring 32 from which the single intravenous drip component illumination device 10 can be hung from a support structure (not shown). The hook ring 32 is attached to the back portion 14 by way of the integral structure 34 having a hole therethrough. And a spring release latch device 36, with a finger pull ring 38 secured thereto, serves to lock the moveable back portion 14 to the base portion 12 in a plurality of vertical positions, as described hereinbelow.
  • The darkened surface 13 on the base portion 12 provides a background that enhances the visibility of the IV drip components being lit by the illuminator assembly 16.
  • FIG. 2A is an orthogonal side view of the base portion 12 of the present single intravenous drip components illumination device, with the moveable back portion 14 removed and shown separately in orthogonal rear view in FIG. 2C and in orthogonal side view in FIG. 2D. FIG. 2E shows the fully assembled single intravenous drip component illumination device 10 in orthogonal side view. FIG. 2B shows the base illuminator assembly 16 from the direction of the arrow A in FIG. 2A. The base illuminator assembly 16 is comprised of a transparent window 18 beneath which are light sources such as light-emitting diodes (LEDs). Other portions of the base illuminator assembly are made of translucent to opaque material so as to prohibit lateral scattering of light from the LEDs or other light sources, so that the light shines primarily upward, toward and illuminates a suspended IV bag and the other IV drip components. The base illuminator assembly 16 of the preferred embodiment of the present invention contains four white LEDs 21 which are mounted upon a circuit board located in the portion of the base illuminator assembly opposite the window 18. Light from the LEDs 21 shines upward upon the intravenous drip bag 20 and the other IV drip components as shown in FIG. 1C.
  • An additional feature of the assembled single intravenous drip component illumination device 10 according to the present invention is shown in FIGS. 3A and 3B. In FIG. 3A, the moveable back portion 14 is shown in its lowest position relative to the bottom 44 of the base portion 12. In FIG. 3B, the moveable back portion 14 is shown in its elevated position relative to the base portion. The two or more different positions of the back portion of the invention 10 are intended to accommodate IV drip bags of varying sizes, or to accommodate other situations wherein the greater overall height of the invention might be useful. The spring-loaded plunger type latch or locking device 36 has a finger pull ring 38 with which the plunger can be withdrawn from the hole 42 in the base portion 12, as shown in FIG. 3B, thereby freeing the moveable backing plate 14 to be moved to and locked into two or more different positions. The spring-loaded plunger type locking device 36 engages a hole 42, shown in FIG. 3B, so as to lock the backing plate 14 firmly to the base portion 12 in the elevated position.
  • The flange plate 40 shown in FIGS. 3A and 3B is also shown in side view in FIG. 2A. Those skilled in the art will readily understand the way that the slot 46 in the moveable back plate 14 (as shown in FIGS. 2C and 3B) engages a corresponding sheet of material 48, shown in FIG. 2A to be disposed between the flange 40 and the back wall 47 of the base portion 12.
  • The inventors envision that two or more of the single intravenous drip components illumination devices 10 according to the present invention can be ganged together so as to hold multiple bags or bottles of IV solutions of different types, for use with multiple patients or with single patients or for other purposes. The inventors further envision that ganged single intravenous drip components illumination devices 10 can be distinguished from one another in dark settings by way of the use of color filters that can be laid over or otherwise attached to the respective windows 18 of the illuminator assemblies 16 of each unit 10 ganged together. Alternatively, the inventors envision that the illuminator assembly can use red, green and blue LEDs having individual controls so that individual primary colors can be “dialed in,” thereby producing any desired identifying illuminating light color.
