Definitions

  • This technical disclosure relates generally to apparatus used in the care of infants. Specifically, this technical disclosure relates generally to apparatus and methods for providing patient access in connection with warming therapy devices.
  • Warming therapy devices such as incubators and radiant warmers, have been used to maintain the appropriate body temperature of newborn infants.
  • An incubator generally provides a transparent enclosure within which heated air is circulated to warm an infant patient.
  • heat may be transferred to the infant patient via convective heat transfer.
  • Warming therapy devices typically include access doors to allow for placement or removal of the infant patient from the warming therapy device.
  • these access doors are often heavy and require two hands to operate, making it difficult to open the door and place the infant simultaneously.
  • These access doors also often comprise the entire side of the enclosure, resulting in significant heat loss when such doors are opened. Further, these access doors often open outwardly, exposing their inner surface to contaminants within the patient treatment area.
  • US Pat. No. 6,641 ,521 discloses an incubator 12 which includes a hood 18 with one or more side walls which are hinged so as to rotate and permit access to a patient chamber 17 containing an infant patient 44.
  • the single hinge of the side wall lies along the bottom of the patient support, resulting in the interior surface of the side wall being exposed to contaminants in the patient treatment area when the infant is placed on the mattress, or removed therefrom.
  • One or more of the side walls also include hand ports formed within the side wall for accessing the infant patient 44.
  • some conventional warming therapy devices also include additional access doors, such as hand ports, which minimize heat loss but still allow for routine examination and care of the infant patient. Some of these hand ports are also difficult to operate, and often require two hands.
  • U.S. Pat. No. 5,817,004 discloses a warming therapy device including a hood 4 with access flaps 6,7 (i.e., hand ports) which may be pivoted about hinges 5 to provide access to an infant patient disposed within the hood.

Further, those of ordinary skill in the art will realize that multiple four (4) bar linkages may be utilized. Such linkages may allow partial opening of a panel 20 by moving only one of the four bar linkages.
  • the use of multiple four bar linkages may also facilitate keeping the panel 20 closer to the base 14 during operation, thereby minimizing the chance of the infant or other medical devices from falling out of the incubation chamber 10, or contaminants entering the incubation chamber.
  • the outer surface or edges of the panels 20, 22 may have handles, knobs, ridges, indentations or other gripping structures to facilitate operating the panels from a first position to a second position. Alternatively an operator may grasp an outside edge of the panel 20, 22.
  • a side panel 20 may be normally disposed in a first, closed position, as shown in Figure 3.
  • a caretaker may grip one of the gripping structures or the side panel 20 itself and pull outwardly (away from the base 14) and downwardly to move the side panel 20 to a second, open position as best seen in Figure 6. If a completely open side panel 20 is not desired, a caretaker may adjust the side panel 20 to a third position between the first and second positions. Exemplary third positions are shown in 4 and 5.

  • both side panels 20 and the end panel 22 are coupled to linkages, and where the top portion 18 is capable of being pivoted away from the patient (as shown in Fig. 2), there may exist approximately two hundred and seventy degrees (270°) of patient access.
  • only one side panel 20 may be mounted to the base 14 through one or more linkages 34, and the other side panel 20 and end panel 22 may be mounted to the base using hinges, sliding tracks, or some other equivalent means.
  • Opening the side and end panels 20, 22 using the linkages 34 generally maintains the panels 20, 22 in substantially the same vertical position throughout the entire range of motion, as shown in Figures 3-7. Accordingly, an outer surface of the panels 20, 22 is always facing outward, and the inner side of the panels 20, 22 always faces inwardly. Keeping the relative orientation of the panels 20, 22 consistent helps to reduce the risk of contamination entering the incubation chamber 10 because outside contact with the inner surface of the panels is minimized.
  • the gaskets or soft protrusions may also help keep contaminants out of the incubation chamber 10 and help keep lines or monitoring devices from falling out of the incubation chamber when the panels 20, 22 are opened.

Preferably, the grommets 36 are located on the edges of each panel 20, 22 (i.e., adjacent to the corner formed by adjoining panels 20, 22). The grommets 36 allow sensor lead wires, air tubes and any other medical lines (e.g., lines 38 in Fig. 8) to remain attached to the infant regardless of whether the panels 20, 22 are open or closed.
  • the grommets 36 may be used in connection with strain reliefs to hold the lines 38 in place, reducing the strain placed on the line as the result of movement of the infant within the incubation chamber 10.
  • the grommets 36 may be constructed of softer material than the side and end panels 20, 22 (e.g., soft rubber).
  • lines 38 may be inserted into the grommets 36 and coupled to the infant patient (if appropriate) prior to closing the panels 20, 22. In this way, the lines 38 are not affected by the opening and closing of the panels 20, 22.
  • the corners of the incubation chamber 10 may also have guards 39, located adjacent to the linkages 34.
  • the guards are positioned between the linkages 34 and the mattress 24, so as to minimize the ability of the infant to contact the linkages 34 from inside the incubation chamber 10.

Abstract

L'invention porte sur un appareil destiné à permettre à un patient l'accès à un dispositif de traitement par la chaleur (par exemple, une couveuse, un dispositif chauffant, etc.). Dans un mode de réalisation exemplaire, l'appareil inclut une base et un couvercle, le couvercle comportant au moins un panneau couplé à la base et pouvant passer d'une première position à une seconde position, le ou les panneaux étant couplés à la base par l'intermédiaire d'au moins un élément de liaison. L'utilisation de l'élément de liaison permet de maintenir le panneau dans une orientation sensiblement identique dans la première et dans la seconde position, empêchant ainsi sensiblement la pénétration de contaminants dans l'enceinte réservée au patient.
