1. Field of the Invention
The present invention relates to physical therapy, more particularly, to devices that aid in helping therapists to lift and transfer patients and to aid in walking, as well as reduce the physical strain on the therapist.
2. Description of the Related Art
Gait belts are traditionally used for safety and to provide a secure hold for therapists when assisting a patient with transfers or gait training. There is a “text book” way to use a gait belt, but unfortunately unique and difficult situations present themselves regularly during the process of physical rehabilitation. Gait belts are mostly applied while the patient is sitting and they often loosen as the patient is lifted, especially with patients who are larger or lack good pelvic and trunk control, causing the belt to ride up to their chest and change the center of gravity. This makes it difficult for the therapist to give manual facilitation where needed and offers the patient little support. Often this causes caregivers to grab patients by their arms or their pants to gain control, which can be harmful and uncomfortable for the patient.
There are harnesses on the market that are used for transfers and gait training. None of them attach to gait belts. They appear difficult to don with many straps and fasteners, and are expensive.
Thigh straps wrap around the patient's thigh, through the crotch, and around the gait belt. They are uncomfortable because they are narrow and dig into the patient's crotch area during use.
The patient lift assist harness of the present invention attaches easily to any gait belt and provides support for a patient by a person aiding the patient.
The harness is single piece of flexible material in a generally elongated X shape with a central crotch portion, two first arms extending from the crotch portion, and two second arms extending from the crotch portion. The first arms are at an angle of approximately 30° to approximately 65° to each other, as are the second arms.
Each arm end has a belt loop through which a gait belt extends. The present invention contemplates a number of different methods for forming the belt loops. In the first, the ends of the arms are folded over and sewn. In the second, separate portions of material are sewn over the ends of the arms.
In the third method, two mirror image harness shape sections are formed from a single sheet, folded to overlap, and the edges sewn. One pair of loops is between the two sections at the fold. The other pair of loops is formed by folding the arm ends over and sewing.
In the fourth method, two mirror image harness shape sections are formed from a single sheet, folded to overlap, and the edges sewn. One pair of loops is between the two sections at the fold. The other pair of loops is formed by sewing the ends of the arms.
The size of the harness will depend on the size of the patient with which it will be used. Typically, the harness is made in standard sizes that fit a range of patients.
After the harness is put in a patient, the gap between the first arms, the gap between the second arms, and the space between first and second arms at the sides expose the gait belt around the patient. These exposed sections of the gait belt provide hand holds for the therapist.
Objects of the present invention will become apparent in light of the following drawings and detailed description of the invention.
For a fuller understanding of the nature and object of the present invention, reference is made to the accompanying drawings, wherein:
The patient lift assist harness of the present invention provides support for a patient by a physical therapist or other person aiding the patient. It attaches easily to any gait belt through robust loops and can be put on and removed while the patient is sitting, laying down, or standing. It offers support through the pelvis, a secure lifting point, and keeps the gait belt at the patient's waist to ensure good body mechanics for both the patient and therapist.
The patient lift assist harness 10 of the present invention is shown in the figures. As seen in
The harness 10 has a central crotch portion 12 with two first arms 14 extending from the crotch portion 12 to free ends 44 and two second arms 16 extending from the crotch portion 12 to free ends 46. The two first arms 14 are at a first angle 20 from each other in the range of from approximately 30° to approximately 65° angle. The two second arms 16 are at a second angle 22 from each other in the range of from approximately 30° to approximately 65°. The preferred angle is in the range of from approximately 40° to approximately 50°. The first arm free ends 44 are generally collinear and the second arm free ends 46 are generally collinear. There is a gap 26 between the first arm free ends 44 and a gap 28 between the second arm free ends 46. The widths of the gaps 26, 28 depend on the size of the harness 10, as described below.
Each arm 14, 16 has a belt loop 38 adjacent to and parallel to the arm free end 44, 46. The present invention contemplates a number of different methods for forming the belt loops 38. In the first, shown in
Alternatively, the harness 10 is composed of two or more layers that are sewn together at the edges. Preferably, the layers are sewn together inside out, and then inverted so that the outside is out. This has the advantage of hiding the sewn seams around the edges.
In the second method, shown in
In the third method, shown in
The second belt loops 38 are formed by a loop extension 82 at the arm ends. The loop extension 82 is at an angle to the rest of the arm 16 so that when the loop extension 82 is folded over an extension fold line 88, as at 84, the loop extension 82 lays over the arm 16, as in
In the fourth method, shown in
The belt loop 38 is wide enough to accommodate gait belts with belt buckles. The typical gait belt is 2 inches wide with a buckle that is 2½ inches wide. The belt loop 38 is in the range of from approximately 2 inches to approximately 4 inches.
The size of the harness 10 will depend on the size of the patient with which it will be used. Typically, the harness 10 is made in standard sizes that fit a range of patients.
In one configuration, the harness 10 is made in two sizes. The small harness is intended for patients up to approximately 200 pounds and up to a 42-inch waist. The width 60 at the crotch is approximately 6½ inches, which increases to approximately 17 inches at the ends, as at 62. Each arm 14, 16 has a width 64 of approximately 5 inches. The gaps 26, 28 are approximately 6 inches. The total length 58 is approximately 27 inches.
The large harness is intended for patients from approximately 175 to approximately 350 pounds and up to a 60-inch waist. The width 60 at the crotch is approximately 8 inches, which increases to approximately 21 inches at the ends, as at 62. Each arm 14, 16 has a width 64 of approximately 6 inches. The gaps 26, 28 are approximately 6 inches. The total length 58 is approximately 35 inches.
To put the harness 10 on the patient, the crotch portion 12 is place between the patient's legs at the crotch. The first arms 14 and second arms 16 are lifted upwardly toward the patient's waist. The gait belt 2 is threaded through the four loops 38, as shown in
The gap 26 between the first arms 14 and the gap 28 between the second arms 16 expose the gait belt 2 at the front and rear of the patient 4. The gait belt 2 is also exposed at the sides of the patient 4. As shown in
The patient lift assist harness 10 of the present invention has a number of advantages over the current belts and harnesses.
1. It has no attached straps or fasteners.
2. It prevents the gait belt from riding up, thereby maintaining where it is designed be. As a consequence, it is safer for patients with G-tubes as it keeps the gait belt from rising and putting pressure on the tube site.
3. It provides secure, comfortable support through patient's pelvis during lifting and sliding. The wide crotch area of the harness minimizes digging into the patient's skin during use.
4. It provides improved leverage for the clinician during lifting which allows for better body mechanics and decreased risk of strain. It decreases the risk of patient falls and injuries during transfers. The increased support provides patients with a sense of security which will improve functional outcomes.
5. It is easy to put on the user with the gait belt by rolling in a supine position or by weight shifting in a sitting position. It is applied to a debilitated patient in the same manner as an adult brief.
Thus it has been shown and described a patient lift assist harness. Since certain changes may be made in the present disclosure without departing from the scope of the present invention, it is intended that all matter described in the foregoing specification and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
