Description
本創作屬於醫療用的移動輔助工具的領域,特別是指一種人力驅動式輪椅,將負責移動用的主動輪及從動輪隱藏於本體內部,大幅縮減體積而能在狹窄的空間中做移動,並能利用操作移動時的動作來訓練上肢者。 This creation belongs to the field of medical mobility aids, especially a human-driven wheelchair, which hides the driving wheels and driven wheels for movement inside the body, greatly reduces the volume and can move in a narrow space, And can use the movement of the operation to train the upper limbs.
按,台灣每年全體身心障礙人口中,以肢體障礙者占最多,針對不良於行的病患,大多會利用如:柺杖、輪椅或助行器等輔具來輔助進行移動,而輪椅是肢體障礙者不可或缺的輔具之一,約有將近70%的行動不便者屬於天天仰賴輪椅的重度使用者,目前大多數的輪椅係採用手推式設計,由以往常見的手推式輪椅也發展出許多不同種類的輪椅,但手推式輪椅仍然是市占率最高的一項,也存在著許多待解決的問題。 According to the press, physically disabled persons account for the most of the total number of people with physical and mental disabilities in Taiwan each year. For patients who are not good at walking, most of them use assistive devices such as crutches, wheelchairs or walking aids to assist in movement, and wheelchairs are physical disabilities It is one of the indispensable assistive devices. About 70% of people with reduced mobility are heavy users who rely on wheelchairs every day. Most of the wheelchairs are currently designed by hand-push type. There are many different types of wheelchairs, but hand-push wheelchairs still have the highest market share, and there are still many problems to be solved.
以國內輪椅輔具市占率第一的品牌為例,此品牌的產品有三大類,其中手推輪椅就佔了60%,且以價格來說,大部分的消費者會選擇購買,相較電動輪椅便宜的傳統手推輪椅;而,本創作人針對手推式輪椅作了許多的資料收集與調查,以及根據使用者的經驗顯示,發現這些手推式輪椅的推進方式都是利用推動輪子外圈的握持部,這些使用者透過沿著輪子的切線方向施力帶動輪子前進,其操作動作過大而容易造成長期雙臂的使用傷害,並且,由於輪椅的體積龐大及長期使用傷害的問題,都降低了輪椅使用 者的自主性,使得他們不得已要仰賴另外一個人的照顧,也是使用者的自主性及自信心降低的主要原因。 Take the brand with the largest market share of wheelchair assistive devices in China as an example. There are three major categories of products for this brand. Among them, hand-held wheelchairs account for 60%. In terms of price, most consumers will choose to buy, compared to electric. Wheelchairs are cheap traditional hand-push wheelchairs; however, the author has done a lot of data collection and investigation on hand-push wheelchairs, and according to user experience, it is found that these hand-push wheelchairs are propelled by means of pushing wheels. The grip part of the circle, these users push the wheel forward by applying force along the tangential direction of the wheel. The operation action is too large and it is easy to cause long-term injury to the arms. Moreover, due to the large size of the wheelchair and the problem of long-term use injury, Both reduce wheelchair use The autonomy of the user makes them have to rely on the care of another person, which is also the main reason for the reduction of the user's autonomy and self-confidence.
而,手推式輪椅的體積較寬,當輪椅使用者獨自在某些室內環境時,行動會相較不便,如:經過某些狹小通道時,容易被卡住或撞倒物品,使得輪椅使用者無法獨自到達他們想去的地方,另外,目前傳統手推輪椅的推進方式是一項效能相當低的動作,在推進的過程中因不斷重複的上肢動作,造成三到五成的輪椅使用者,有肩膀、手肘、腕關節疼痛的經驗。 However, the hand-held wheelchair is relatively bulky. When wheelchair users are alone in certain indoor environments, their movements are relatively inconvenient. For example, when passing through certain narrow passages, they are easily caught or knocked down, which makes the wheelchair use. The person cannot reach the place they want to go alone. In addition, the current traditional hand-push wheelchair propulsion method is a very low-efficiency action. During the propulsion process, the repeated upper limb movements cause 30 to 50% of wheelchair users. , With experience of shoulder, elbow and wrist pain.
為了改善這些問題,本創作人特別針對操作方式重新做了設計,利用操作手把連動齒輪帶動輪子移動的原理,使乘坐者不須用雙臂推動自身重量,即可用更加省力的方式做移動,更由於這樣的新操作方式不須直接接觸兩側的大輪,以將大輪縮小移至座椅下方大幅縮減輪椅的寬度,讓本創作與現有的手推式輪椅相比,在操作上更省力能夠減輕上肢的壓力,也使得輪椅使用者更願意出門與社會接軌提升自信。 In order to improve these problems, the author has redesigned the operation mode in particular, using the principle that the operating hand moves the linked gear to move the wheel, so that the occupant can move in a more labor-saving manner without pushing his own weight with both arms. Because this new operation method does not need to directly touch the large wheels on both sides, the large wheels are reduced to move under the seat to greatly reduce the width of the wheelchair, making this creation more labor-saving in operation than the existing hand-held wheelchairs. Reducing the pressure on the upper limbs also makes wheelchair users more willing to go out and connect with the society to enhance self-confidence.
有鑒於此,本創作之一目的,旨在提供一種人力驅動式輪椅,俾利用精心設計的一本體、一扶手架及一傳動模組,改變原有的手推式輪椅的使用缺陷及操作方式,達成縮減體積而能在狹窄空間中透過操作該等操作把手來進行移動,並能有助於行動不便者進行上肢運動等功效。 In view of this, one of the purposes of this creation is to provide a human-driven wheelchair, using well-designed a body, an armrest frame and a transmission module to change the use defects and operation methods of the original hand-push wheelchair It achieves a reduction in volume and can be moved by operating these operating handles in a narrow space, and can help people with disabilities to perform upper limb movements and other functions.
