Description
Description AID APPARATUS Technical Field
[0001] The present invention relates generally to an aid apparatus for enabling the assisted mobility of a disable person e.g. to be raised from a sitting position to a standing position, transferring and vice versa
Background Art
[0002] Today, there is a large number of patients; e.g. disable, old and physically challenged persons; who are limited to beds, wheelchairs, chair or toilets and who need the assistance of care givers; e.g. therapists, relatives; to help them to a standing position from a sitting position or to help them to be transferred from a bed and/or a wheelchair.
[0003] Some of these patients live in special living homes and other in their ordinary homes. The special living homes are becoming twice as costly as home care. It is not hard to predict that the costs for special care within the near future will raise due to the increasing number of elderly people. Therefore, it would be very profitable for the society if the elderly people could be taken care of in their home environment as long as possible with the care being performed by relatives in the homes, such as a husband or a wife. This would also very much likely be appreciated by the fimily concerned.
[0004] There are however a number of presumptions for the elderly person to remain at home. For instance, the environment must be safe and secure, comfortable and functionally adapted. For a person with reduced capability and disability a big concern is the concept of raising from a sitting position into a standing position.
[0005] Such attempts are often avoided both from the patients and the care givers due to the fear that the patients can fill and receive lesions. When such attempts are done, sometimes the patients are so heavy that the care givers may injury themselves and/or may in a lapse of time result in muscle strains and back injuries.
[0006] In order to solve these problems, numerous devices, which assist the patients, have been developed. Nowadays, some of these devices make use of slings, or the like, which hold and secure the patient and lifting mechanisms, which enable the patient to be moved from a sitting position to a standing position in a walking or transferring device.
[0007] US 6,568,002 discloses an aid apparatus for raising a disabled person from a sitting
position to a standing position, which apparatus includes a wheeled base and a lifting arm having a free end, which supports a lifting sling brought round the body of a disiile person, approximately at breast-high.
[0008] US 6,389,619 discloses a sit-to-stand lift that can cause a person to follow a natural path of standing up and sitting down. During standing up, the most natural path comprises of carrying the body drove the feet by a substantially horizontal movement in forward direction of the person, where after the body is brought into a standing position by a substantially vertical movement, wherein the shoulders describe a concave, elliptical path. This path can be followed in reverse direction when sitting down. The existing sit-to-stand lift makes use of an articulated carrying body which consists of two arms pivotally connected to each other and which moves along the desired path through a compound movement of the two arms of the part of the carrying body adapted to engage on the person, for instance handgrips or a sling. A drawback of this apparatus is that the movements of the two arms must be adjusted very precisely to each other. The apparatus is therefore relatively complex and in general relatively susceptible to malfunction and expensive to produce. The slings are place under the arms of a patient and the patient is leaning backward, which causes an unpleasant feeling of insecurity to the patient.
[0009] US 6,175,973 discloses an apparatus for assisting a person in achieving a standing position. The apparatus include a base, a frame extending upward from the base, a lifting arm pivotally coupled to the frame, a platform upon which a person can stand, and an actuator which is controlled to raise and lower the lifting arm. The apparatus also includes a sling assembly which is remov±ily attach±ile to the lifting arm. The sling assembly is designed to encircle the body of a person. The sling assembly also includes at least one caregiver handle on an outer back portion thereof.
[0010] US 6,135,131 discloses a device for use in cooperation with an apparatus for lifting a person from the seated position to a standing position wherein the apparatus has at least one hollow handle extending downwardly when the person is in a standing position. A harness is strapped to and secured around the back of an individual.
[0011] These lifting and/or transferring devices suffer from a number of drawbacks e.g.:
[0012] - the physical size of these devices is so large that it is almost impossible to manoeuvre and pass through narrow door passages;
[0013] - uncomfort±ile slings that are place under the arms of a patient, making the patient to lean backward, which causes an unpleasant feeling of insecurity to the patient, when he is raised from a sitting position to a standing position;
[0014] - many complicated adjust±ile parts of the devices;
