Definitions

  • Sprung ABSTRACT A medical light especially useful in combating hyperbilirubinemia of neonates.
  • the light comprises a neon bulb mounted in a housing of size and construction such that the light can be placed in an incubator.
  • TRANSFORMER REGULATOR PATENIEU JUL 91924 SHEEI 2 [IF 2 MEDICAL LIGHT AND COMBATING OF I-IYPERBILIRUBINEMIA BACKGROUND Radiation in the visible spectrum range has become recognized as a treatment, both therapeutically and prophylactically, for hyperbilirubinemia. Blue light is generally regarded as the most effective.
  • a housing containing, e.g., 8 to 10, fluorescent bulbs in planoparallel array, is mounted on a floor stand.
  • the height of the housing can be adjustable.
  • the-lamps are disposed with the light housing positioned outside and over an incubator, which is outfitted with a transparent top cover,.for radiation through the incubator cover to the infants body.
  • a filter for light of wave length shorter than that of blue can be provided. Thereby ultra-violet radiation, which is generally considered to be undesirable, can be eliminated.
  • masking is done by wrapping the babys head, including the eyes, in bandages.
  • Another disadvantage is that the light tends to heat up the incubator.
  • the energy output of the fluorescent bulbs decreases with use.
  • the decrease in radiation of blue light of wavelength 400 to 480 nm (nanometers) is reported to be as high as 44 percent in 200 hours. Treatment periods are, for example, 48 to 144 hours.
  • blue light may cause nausea so that the nursing staff may be bothered by the treatment.
  • Still another disadvantage is that the floor stand, fluorescent lamps are awkward to use. They are bulky and inconvenient to move about. To regulate intensity of radiation, the height of the light housing is-adjusted, or the bulbs are changed.
  • Ruiter U.S. Pat. No. 1,337,798, discloses a housing outfitted with lights for receiving a part of the trunk of a patient.
  • Riess et al. U.S. Pat. No. 2,300,008, disclose a neon light for placement on parts of the body.
  • Bacon, U.S. Pat. No. 2,003,527 discloses I a light adapted to be moved over the body.
  • Hess U.S. Pat. No. 1,900,342, discloses an incubator for infants outfitted with a therapeutic light.
  • the invention provides for treatment of hyperbilirubinemia of neonates unaccompanied by the aforementioned disadvantages of the prior art practices.
  • the infant is treated by directing radiation of a neon light onto the infant for a time sufficient to counteract hyperbilirubinemia. It is particularly contemplated that the infant be in an incubator during the'treatment, with the neon light positioned within the incubator.
  • the light comprises a housing opened at the bottom and at one end thereof for placement of the housing over the infant with the head without the housing and the trunk covered by the housing.
  • a neon light is mounted within the upper part of the housing for directing of emitted light to the trunk of the infant.
  • the light includes a shield mounted on the end adjacent the infants head, for shielding the infants head from the emitted light.
  • the light emits radiation in the blue por-. tion of the visible spectrum, and filter means are provided for absorption of ultra-violet radiation before transmission of the light to the infant.
  • the housing can have closed sides, which can be transparent, or, if desired, the inner surface of the sides can be reflecting for inward reflection of radiation to the infant.
  • the end of the housing opposite the head end can be opened for disposition of the infants legs, at least partially, without the housing.
  • the housing can be of such dimensions that the infants arms can be disposed without the housing.
  • the lamp of the instant application provides substantial reduction in lght spillage. Also, masking of the infants head is not necessary as the shield provided with the lamp prevents radiation from striking the infants head. By reason of the character of the neon light, undesirable heating up does not occur. Also, reduction in light intensity with use does not occur to an objectionable extent. To avoid.
  • FIG. 1 is a perspective view of a medical light according to the invention, including a schematic illustration of the power supply for the light; and I FIG. 2 is an end view from the head end, taken along 2 2 in FIG. 1.
  • the medical light 1 includes a housing 2 composed of a closed top 3, closed sides 11, foot end 4 having an opening'6 for projection therefrom of an infants legs, and head end 5 which is open to permit projection of the infants head from the housing.
  • the opening 8 in the head end 5 is an inverted U-shaped opening formed in a plate 9 which is slidably mounted on the head end 5 by way of guides so that the plate can be manually moved up and down.
  • the overall size of the medical light in inches, can be 8 8 8to 12X 12X l2,preferably9 9 9to 11 X ll X 11.
  • a height of 9% inches and a length and width of 10 inches has been found to be particularly well suited.
  • the light is sized so that it can fit within an incubator, i.e., within the incubator with the incubator top cover in place.
  • the lamp is light weight and can be easily moved about by members of the nursing staff.
  • a handle 7, (FIG. 2), is provided for the unit.
  • the light is sufficiently heavy so that it resists movement by the infant.
  • the top 3 and the upper portion 11a of the housing can be and preferably is opaque so that light is not transmitted therethrough.
  • the lower portion 1 lb of the sides can be transparent or opaque. Also, it can have an inner surface which is reflecting so that radiation is reflected toward the infant. Desirably the lower portion of the sides is amber plastic, e.g., Plexiglas which does not transmit radiation in the range of 400 500 nm, i.e., blue light.
  • the head end and the foot end of the housing can be of the same construction as is mentioned for the sides.
  • the neon light comprising the tubing 12 and electrode caps 14, rest on support bars 13 in the upper portion of the housing.
  • Air vent holes 18 are provided in the upper portion of the housing to prevent any undesirable heat build up.
  • the tubing 12 can be 9 mm id, 6 feet in length.
  • the tubing can be Corning 6-1 lead glass, non ultra-violet emitting, filled with a noble gas, e.g., argon, and can be coated with fluorescent lamp phosphor, so that the lamp will preferentially emit blue light, e.g., radiation of wave length in the range of 400 500 nm, preferably in the range of 425 475 nm.
  • the ends of the tubing are connected with power leads from the cable 15, via electrode caps 14.
  • the contents of the tubing are non-toxic, and free of mercury.
  • a pure noble gas is used, e.g., pure argon. Then breakage would not contaminate the incubator.
  • Plexiglas plate 17 is positioned between the upper portion 11a and the lower portion 11b of the sidewalls.
  • the plate can be UVA B plexiglass of Rohn and Hass, Vs inch thick.
  • the power supply is indicated in P16. 1.
  • a neon light transformer for transforming 120V supply to 3,000 4,000 output is used.
  • Cable 23, including a voltage regulator 22 is provided for connection to the 120V supply.
  • the power unit includes an on-off switch 25, and an indicator light 24.
  • a safety plug 21 which is a four contact CPI-I No. 49,638 plug, is provided for connecting cable to the power supply. The safety plug insures that the high voltage side of the transformer will be closed, before closing of the low voltage power input side.
  • the output of the neon light can be controlled by the voltage regulator 22, so that a selected degree of radiation can be utilized.
  • the current of the output side of the transformer can be about 30 miliamps.
  • a medical light suitable for placement in an infant incubator with the incubator top cover in place comprising:
  • a neon light mounted within the upper part of the housing for directing of emitted light to the trunk of the infant with the housing placed as aforesaid
