  • Publication number: 20190262201
    Abstract: A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

  • Patent number: 6705862
    Abstract: A convertible buccal tube is disclosed which includes an arch wire slot covered by a separable cover. The cover includes a mesial or front flared portion to facilitate placing the end of an arch wire therein without undesirably stressing the cover. The cover is further secured to the buccal tube body by integral seams, brazing or other adhesive means that are varied in strength mesially-distally, with about 50% greater force being required to separate the cover at the mesial end thereof. The cover and increased strength seams provide that the cover is not prematurely separated from the buccal tube, particularly during installation of an arch wire.

  • Patent number: 5292248
    Abstract: An orthodontic appliance has a tooth-abutting surface oriented at an acute angle relative to the base of an arch-wire slot. A lip bumper tube of the appliance is reverse offset relative to the base of the arch-wire slot to obtain more accurate manipulation of the force and torque vectors applied to the tooth. The angle of the base also reduces occlusal interference by gingivally inclining the lip bumper. Wedge-shaped occlusal tie wings further reduce occlusal interference. An auxiliary hook of the appliance is shaped so that its extension in the buccal direction is less than that of the lip bumper tube to reduce patient irritation and discomfort.
