Description

Improved writing auxiliary tool

Technical Field

The present utility model relates to writing instruments and, more particularly, to an improved writing aid.

Background

Patients with cerebral stroke, peripheral nerve injury, hand burns, hand trauma, etc. often suffer from hand sensory and motor dysfunction, such as limited thumb and index finger pair, limited finger function, and inability to control hand muscles to perform fine movements, such as pen-hold writing, spoon-hold feeding, etc. These disorders can affect the ability of the patient to use the upper limbs and hands, reducing their daily life/work capacity and quality of life. For patients with hand limb function training disorder and reduced finger flexibility, rehabilitation therapists generally perform upper limb rehabilitation training and finger fine function training on the patients; for patients with limited functions such as contracture of the tiger mouth, palm alignment of the thumb and the index finger, finger alignment and the like, modes such as making hand orthoses or drawing/training by manipulation are generally selected to improve the hand functions of the patients, however, for patients needing urgent writing demands by pens, for example, for special important occasions such as examination, signature and the like which cannot be replaced by electronic signatures, how to improve/train the writing functions of the patients is one of important points and difficulties of the rehabilitation process. Meanwhile, therapists can use various writing auxiliary devices to help patients maintain the palm and finger functions and fix the sign pen at the same time, and guide or help the patients to perform hand function rehabilitation training aiming at recovering or improving hand movement functions and practical capacities of daily life.

In fact, because of the different causes and limited types/degrees of hand dysfunction caused by cerebral stroke, peripheral nerve injury, hand burn, hand trauma, the training tools/auxiliary tools for the above people to hold pens for writing are different in size and various in variety, and the auxiliary tools for writing commonly used in the market mainly comprise: pen-holding cap, soft pen cap, triangle pen cap, three-finger pen-holding cap, pen-holding clip, thickened pen, book clip, mouth stick and accessories (the mouth occlusion capability is utilized to replace part of fine functions of hands, and the pen-holding cap is suitable for patients with upper limb functional paralysis or missing), etc. The existing tiger-mouth hand-shaped positioning pen holding device can fix the pen at the tiger mouth, but the human body efficacy, wearing comfort and writing practicability have larger improvement space; the existing thickening pen, triangular pen cap and three-finger pinching pen cap have conditional restrictions on the hand functions of a patient, and the patient needs to have certain finger-to-finger and thumb-to-palm functions to be used normally.

However, the above-mentioned conventional writing aid is not ideal for patients with limited functions such as contracture of hand and tiger mouth, palm alignment of thumb and index finger, and finger alignment, and has no aid style/product for specific people with hand dysfunction, and is difficult to popularize.
