Patent Application
20210129956
This disclosure is in the field of lift vests that enable a caregiver to assist a patient wearing the vest to move from one position to another. The vests typically include a base garment shaped to cover at least a substantial portion of the torso (chest, abdomen, and back) of the patient and belts connected to the base garment that provide hand holds for the caregiver. U.S. Pat. No. 6,122,778 to Cohen, the contents of which are incorporated by reference herein, provides an example.
The prior art lift vests work best in non-emergency situations, where there is sufficient time to equip the patient with the vest, and when worn by patients that can bear weight. Even when worn by weight-bearing patients, the vest may slide upwards during use, causing the top or chest belt to move upwards towards the patient's arms.
Embodiments of a lift vest of this disclosure include a base garment shaped to cover at least a substantial portion of an upper torso of a patient, a waist belt connected to the base garment, and a pair of crotch belts removably connected to the waist belt. Removable connections may include quick-release buckles of a kind known in the art, hook-and-loop fastener of a kind known in the art, or some combination of the two. The connections may be adjustable connections.
In other embodiments, the base garment includes a chest and a waist belt interconnected by cross-webbing. Pulling on one or both of the belts in any direction causes the webbing to tighten about the wearer's torso.
In some embodiments, the lift vest includes a pair of knee belts connected to the waist belt. The knee belts can be fixed to the waist belt or removably connected to it. The knee belt may include a removable connection along its length.
Other embodiments of a lift vest of this disclosure include a base garment covering the upper torso below the armpits and having a single belt connected to garment that provides a hand hold.
In embodiments of a lift vest of this disclosure, the vest includes a garment with a lifting structure that helps transfer a caregiver's lifting force to the wearer's torso so the wearer may be lifted or moved. For purposes of this disclosure, torso refers to an area generally containing the chest, abdomen, and back. Upper torso means the chest and upper back (opposite that of the chest).
Lower torso means the abdomen and the lower back (opposite that of the abdomen). A lift vest means a device worn by a patient as a clothing item and configured for safe patient handling and mobility during transfer and repositioning of the patient in any direction: front, back, or side. The vest may be made of fabric suitable for clothing items. The vest is foldable and rollable (unlike vests that contain flotation)
Referring to the drawings, embodiments of a lift vest 16 of this disclosure include a basic fabric garment 18 that is similar in many respects to a sleeveless vest but includes a lifting structure surrounding and forming a part of the vest that provides numerous hand hold places that enable a caregiver to assist the vest wearer. The garment 18 may include sleeve holes 20, a front 24 that may be closeable open front, a neck opening 26, and may be sized to cover the wearer's torso. The neck opening 26 may be a V-shape or rounded neck opening. In other embodiments, the garment 18 is a poncho-style garment (no closeable open front). In some embodiments, the garment 18 does not include sleeve holes 20 and is intended to only cover the upper torso below the armpits. The garment 18 may include a fire-resistant fabric of a kind known in the art.
The lifting structure may include one or more belts 32, 36, 40, 54 made of webbing and received by respective loops 72, 74, 84, 86 connected to the garment 18. A double belt loop 70 may form loops 72, 74. In some embodiments, the garment 18 includes only a chest belt 36. Waist belt 32 may include a single or double adjustable buckle 34 so that the length of waist belt 32 can be adjusted to snugly but comfortably fit around the waist of the wearer. Similarly, chest belt 36 may include a single double adjustable buckle 38 so that the length of the chest belt 36 can be adjusted to snugly but comfortably fit around the upper torso portion of the patient. Waist belt 32 and chest belt 36 may be arranged horizontal and parallel to each other. In embodiments, the vest 16 may include shoulder straps 40, 54 the same or similar to those as disclosed in U.S. Pat. No. 6,122,778 to Cohen, the contents of which are incorporated by reference herein. The straps 40, 54 may include a shoulder lift strap secured to the straps 40, 54. Loops 84, 86 may serve as the lift strap.
Embodiments of the lift vest 16 may include a pair of crotch belts 102 removably connected to the waist belt 32 by connectors 104. Connectors 104 may include quick-release buckles of a kind known in the art, hook-and-loop fastener of a kind known in the art, or some combination of the two. The connections may be adjustable connections. The crotch belts 102 help prevent the vest 16 from sliding upwards during vertical lifting movements. This is especially helpful when the wearer cannot bear her or his own weight. The crotch belts 102 may be crossed. See
