Description

    BACKGROUND OF THE INVENTION
  • An embodiment of this invention relates to a head harness assembly for supporting an interface device for communicating a fluid to a user. More particularly, an embodiment of this invention relates to an adjustable head harness for supporting a respiratory device.
  • In the art of respiratory devices, there are a variety of devices that engage the nose and/or mouth of the user in order to provide a gas at positive pressure for consumption by the user. The uses for such respiratory devices range from high altitude breathing (i.e., aviation applications) to mining and fire fighting applications, to various medical diagnostic and therapeutic applications.
  • One requisite of such a respiratory device has been that they are secured to a head of the user to provide the mouth and/or nose with the gas being supplied. Commonly, in prior respiratory devices, methods of securing the respiratory device to the user's head are either ineffective, effective for only a short time, or cause considerable discomfort for the user. This problem is most crucial in those applications, especially medical applications, which require the user to wear a respiratory device continuously for hours or perhaps even days. In such situations, the user will not tolerate the respiratory device for long durations and optimum therapeutic or diagnostic objectives thus will not be achieved, or will be achieved with great difficulty and considerable user discomfort.
  • Past methods of securing the respiratory device to the user's head have included a rubber cap in combination with elastic bands and safety pins to hold the respiratory device. Such a device has been ineffective as a long-term solution since it requires repeated adjustments, which irritate the user and may reopen existing wounds. Additionally, the rubber cap retains body heat and causes additional discomfort to the user.
  • To overcome these problems, a head harness is needed which effectively secures the respiratory device to the head of the user, but does not create discomfort. Additionally, it is desirable that the head harness be made of a material that is suitable for use in a medical diagnostic imaging method or apparatus or device, such as X-ray, magnetic resonance imaging (MRI) devices, computed tomography (CT) scanning devices, ultrasound scanning devices and the like.

  • DETAILED DESCRIPTION OF THE INVENTION
  • An embodiment of the invention will be described below with reference to a head harness for a respiratory device fitted to the head of a user for communicating breathable gas to airways of the user, for example in the administering of continuous positive airway pressure (CPAP) or a bi-level positive airway pressure (BIPAP) treatment. However, the embodiment of the invention is not limited to this particular field of use and is equally suited for respiratory devices used in assisted respiration or mechanical ventilation, and other interface devices, for example, feeding tubes, etc.
  • FIG. 1 depicts an exemplary embodiment of a head harness 10 for a respiratory device, as worn by a patient. The head harness 10 is disposed about the head 12 of the patient such that the head harness 10 supports a bilateral tube assembly 14 supplying a gas to the patient. More specifically, supplying a gas to a nose of the patient via a lateral tube in fluid communication with the bilateral tube assembly. It will be appreciated by one skilled in the art that although this exemplary embodiment discloses a bilateral tube assembly 14, the head harness 10 is also adaptable to support other respiratory devices. The head harness 10 includes a headband section 20, an adjustable crown support section 22, an upper tube support section 24, and a lower tube support section 26.
  • FIG. 2 illustrates the head harness 10 of FIG. 1 removed from the patient and disassembled. The headband section 20 provides adjustable attachment of the head harness 10 to the head 12 via a single flexible member. The headband section 20 includes a main strap 30, an attachment device 32 (see FIG. 1), and a plurality of connectors 34. The main strap 30 is made of an elastic material configured to extend around the head 12 at a level above the patient's eyes and ears. In an exemplary embodiment, the main strap 30 is made of an approximately 1½-inch elastic cotton band to provide a comfortable yet secure fit. Additionally, the relatively small width of the main strap 30 prevents an excessive buildup of body heat inside the main strap 30. The main strap 30 includes a first end portion and a second end portion. In an exemplary embodiment, the head harness 10 is disposed on the head 12, such that the attachment device 32 is located at a position above and between the left eye and left ear, as shown in FIG. 1, to facilitate operation of the head harness 10 from a frontal direction relative to the head 12.
  • Although the main strap 30 is made of elastic material, the length of the main strap 30 is optionally selected to conform to a head circumference of the patient. For example, the main strap 30 is of three separate lengths corresponding to small, medium, and large head circumferences.
  • The attachment device 32 includes a first attachment part 35 and a second attachment part 36 disposed at first and second end portions of the main strap 30, respectively. The attachment device 32 is configured to affix first and second end portions to each other.

The adjusting member 44 according to an exemplary embodiment includes a plastic apparatus shaped like a figure “8” having a central bar 46 defining two apertures 47. The second end of the strap 40 is attached to the central bar 46 and a portion of the strap 40 is fed through each of the two apertures 47 to provide a means for adjusting a length of the strap 40 by sliding the adjusting member 44 along the strap 40 in a direction closer to the S-hook 38 in order to lengthen the strap 40, and by sliding the adjusting member 44 along the strap 40 in a direction closer to the center ring 42 to shorten the length of the strap 40.
  • FIG. 5 is an enlarged view of the S-hook 38 of the head harness 10 of FIG. 2 according to an exemplary embodiment. The S-hook 38 is an engaging device, which connects the strap 40 to one of the plurality of connectors 34. The S-hook 38 of an exemplary embodiment includes a closed end portion 48 and an open end portion 49. The strap 40 passes through the closed end portion 48 and the open end portion 49 is insertable into the receiving loop of one of the plurality of connectors 34 to form a connection between the headband section 20 and the adjustable crown support section 22. The S-hook 38 is made of non-metallic material, for example, plastic, to allow the head harness 10 to be worn in the MRI, CT scan, etc.
  • In an alternative exemplary embodiment, one S-hook 38 and one corresponding connector 34 are replaced by one strap 40 that is permanently affixed to the headband section 20. As shown in FIG. 6, permanently affixing one strap 40 to the headband section 20 ensures that the adjustable crown support section 22 does not become separated from the headband section 20 and get lost, while still allowing substantial freedom to adjust locations of remaining S-hooks 38. Although in FIG. 6, permanently affixing one strap 40 to the headband section 20 is accomplished by passing a portion of one strap 40 through a fixed loop, which forms one connector 34, other suitable methods of permanently affixing one strap 40 to the headband section 20 are also envisioned. Additionally, in an exemplary embodiment, one strap 40 is permanently affixed to the headband section 20 at a region of the headband section 20 corresponding to a position behind a back left ear of the head 12 in order to provide an alignment reference for the remaining straps 40.
  • FIG. 7 is an enlarged view of the upper tube support section 24 of the head harness 10 of FIG. 2 to an exemplary embodiment. The upper tube support section 24 provides support for an upper portion of the bilateral tube assembly 14 by ensuring that the upper portion of the bilateral tube assembly 14 is secured to the head 12. In an exemplary embodiment, the upper tube support section 24 includes two tube holders 50. The two tube holders 50 are disposed such that each tube holder 50 is near a corresponding right or left temple region of the head 12, thereby preventing the bilateral tube assembly 14 from interfering with vision, hearing or comfort of the user. Each tube holder 50 includes a holder strap 52 and rings 54. The holder strap 52 has a first end and a second end. The first end of the holder strap 52 is attached to a first ring 56 and the second end of the holder strap 52 is attached to a second ring 57. A portion of the holder strap 52 near the first end is affixed to the headband section 20. A third ring 58 provides for adjustment of the holder strap 52 to engage and clasp the upper portion of the bilateral tube assembly 14. Following the portion of the holder strap 52 that is affixed the headband section 20, the holder strap 52 is passed through the third ring 58, passed through the first ring 56, and passed back through the third ring 58 before extending toward the second end, thereby forming an adjustable clasping mechanism to engage and clasp the upper portion of the bilateral tube assembly 14. However, it is contemplated that the upper tube support section 24 may include other means of securing the bilateral tube assembly including hook and loop fasteners, straps, buckles, laces, etc.
  • Referring to FIGS. 2 and 6, the lower tube support section 26 provides support for a lower portion of the bilateral tube assembly 14 by ensuring that the lower portion of the bilateral tube assembly 14 is secured to the head 12. Supporting the bilateral tube assembly 14 at two separate locations provides superior support for the respiratory device, which prevents a need to continually readjust or tighten the head harness 10 which can irritate the patient's wounds or cause discomfort, both of which may prevent proper and timely healing.
  • The lower tube support section 26 includes a base member 60, a cross member 62, and tube loops 64. The base member 60 extends from the headband section 20 and is affixed at one end to the headband section 20 at a portion of the headband section 20 corresponding to a back of the patient's neck. The base member 60 is made of a flexible material or fabric, for example, cotton, which extends downward from the headband section 20 toward the patient's back. The base member 60 extends from about 2 inches to about 3 inches from the headband section 20 and terminates in a loop of fabric, which forms a through hole 61. The cross member 62 is made of a similar material to that of the base member 60. The cross member 62 passes through the through hole 61 and extends toward oppositely disposed ends. The cross member 62 slides freely within the through hole 61. The cross member 62 extends in a direction substantially perpendicular to the direction of the base member 60. A tube loop 64 is disposed at each of the oppositely disposed ends. The tube loop 64 according to an exemplary embodiment includes a loop of material that is attached at both ends of the cross member 62. In an alternative exemplary embodiment, the tube loop 64 is adjustable using a figure “8” shaped adjuster similar to the adjusting member 44. The figure “8” shaped adjuster is slidable along the cross member 62 to adjust the size of the tube loop 64 and thereby adjust a tightness with which the tube loop 64 engages the bilateral tube assembly 14. The lower portion of the bilateral tube assembly 14 passes through each corresponding tube loop 64, which provides support to the bilateral tube assembly 14. The tube loop 64 and the cross member 62 are elastic to allow the head 12 to turn freely without displacing the bilateral tube assembly 14.
  • An embodiment of a head harness 10 has been described, which is capable of providing support for a respiratory device while enhancing the comfort of the patient.
