Patent Application
20170189253
The present invention generally relates to improvements in wheelchair to enable the disabled patient to stand up with little or no assistance.
The art is replete with a wide variety of prior art devices, designed to assist the wheelchair users in achieving a standing position from a sitting position. Such devices have ranged from simple hand rails, which require the user to lift most of his or her body weight without mechanical assistance, to fully mechanized devices which perform the lifting and support functions almost completely independently of the user of the device.
Wheelchairs, as a matter of interest to hospitals, patient facilities, and private persons, are a major concern. For the most part, wheelchairs are designed to transport patients from one location to another with a minimum of difficulty. Indeed, most wheelchairs include the capability of allowing the wheelchair occupant to move the chair of his own accord. Predominantly, this is done using human arm and hand power. However, there are those designs that involve motorized driving means.
In cases where a patient is capable of driving their own chair, the difficulties of the hospital or support staff that may be concerned with such propulsion are minimal. Usually, such handicapped persons can manage for themselves and are able to help the attendant in whatever fashion necessary during transfer to and from the wheelchair. However, there is a much larger concern when medical officials are required to move a patient that is incontinent or has the functional loss of one or more limbs. Such patients often must be moved completely with the help of others as they do not have the capacity of independent motion. In such circumstances, especially in the hospital environment, these patients may require the help of two or more attendants to move the individual from chair to bed or vice versa.
Wheelchairs are already known, which are especially used for paraplegic patients, and which enable the patient to stand up. It is indeed a recognized fact today, that it is necessary for multiple reasons—and in particular physiological and psychological ones—to enable a handicapped person to stand up to a vertical position during the day. This operation which many specialists call “uprighting”, has been essentially developed with the help of fixed installations giving the handicapped person the facilities of standing up.
Certain wheelchairs have a movable seat and backrest, which also enable the patient to stand up. Various prior arts have disclosed hair extensions for example, U.S. Pat. No. 3,964,786 issued Jun. 22, 1976 to Mashuda discloses a wheelchair in which the seat, back and leg portions are so articulated and separately actuable, by power means, under control of the occupant, as to enable the occupant to assume any of one of three positions, either sitting, standing or reclining. From the figures and description, it does not appear that the anthropometric averages would be maintained.
U.S. Pat. No. 4,437,537 issued Mar. 20, 1984 to Ausmus describes an occupant operated motor driven vehicle for supporting handicapped occupants adapted to be tilted forward by the occupant for retrieving articles lying on the vehicle's support surface, and to be restored to vertical operating position. The platform means does not appear to be integrated into any sort of wheelchair, nor does it appear to maintain anthropometric averages.
U.S. Pat. No. 4,456,086 issued Jun. 26, 1984 to Wier et al. discloses an integrated wheelchair and ambulator which allows a paraplegic to stand, although it contains a platform which is undesirable in order to maintain anthropometric averages. Therefore, it is a primary object of the present invention to provide an invalid mobility device or stand-up wheelchair in accordance with the present invention which is capable of allowing an invalid to stand, while maintaining the anthropometric averages to allow the invalid to experience approximate normal motion and simulated normal activities and mobility but will allow routine functions to be performed like non-invalid counterparts.
The foregoing patents reflect the state of the art of which the applicant is aware and are tendered with the view toward discharging applicant's acknowledged duty of candor in disclosing information which may be pertinent in the examination of this application. It is respectfully stipulated, however, that none of these patents teach or render obvious, singly or when considered in combination, applicant's claimed invention.
It is therefore desirable to have a dependable, mechanically simple device to enable even persons with a full lower body disability to easily and safely move themselves between sitting and standing positions while utilizing their own skeletal structure for support. Additionally, it is desirable that such a device is enabled with lift assisting tilting that is suitable for all types of disabled patients.
In view of the foregoing disadvantages inherent in the known types of wheelchair in the prior art, the present invention provides an improved wheelchair for better mobility of people with disabilities. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved arrangement for a wheelchair, which has all the advantages of the prior art and none of the disadvantages.
It is an object of the present invention to provide an improved wheelchair. With the instant apparatus, the transportation and handling of disable patients in simple way requiring no help. Accordingly, one of the objects of the present invention is to provide an improved wheelchair that facilitates the movements of patients from sitting position in a wheelchair to standing position.
This invention provides for a wheelchair including a hydraulic pump below the patient seat panel actuated using a push button to lift the user to their feet without limited or no help. Thus, the attendant is not required to summon help as he or she does not need to physically lift the patient from the chair. The individual may be moved from the seated position to standing posture. The wheelchair has large rear wheels that allow the patient to be independently mobile. The use of the large rear wheels allows the patient to push himself to whatever destination they may have in mind.
An aspect of the invention is to provide a hydro wheel chair having an adjustable seat belt for safety of the patient from falling during using the chair.
Another aspect of the invention is to provide a hydro wheel chair having a lift and tilt feature.
Still another aspect of the invention is to provide a hydro wheel chair having a remote control or push button or hand gear.
