Aluminium alloy crutch and stainless steel crutch

Let me introduce how to better protect crutches and avoid the embarrassing situation of changing a pair of crutches every six months.

Material Selection of Crutches

Crutches are generally divided into aluminium alloy and stainless steel. Aluminum alloy is lighter than stainless steel and does not rust. It is suitable for the old people who are physically weak. Stainless steel bears heavy loads, is heavier than aluminium alloy. It is firm, not easy to deform, and has good safety. It is suitable for young people.

Selection of Anti-skid Sleeve Pad

After limb patients use axillary crutches, the weight of crutches is stressed by the base of crutches. Generally, medical manufacturers add an anti-skid sleeve pad on the base. Low-performance anti-skid pads are easy to fall down when they meet the situation of smooth ground or water. There are numerous experiences. At present, there is a kind of bull tendon anti-skid pad on the market, which is wear-resistant, stable and anti-skid.

Selection of Inner Pipe Support Points

Each person's height and arm length may be different, adjust the middle part of the crutch, the inner tube is covered by rubber tube, the whole crutch will bend outward in the process of continuously giving pressure to the metal tube in the arm, unless changed one side at intervals, otherwise the middle or slightly downward part will break, the crutch made of aluminum alloy material is the most obvious.

Height Selection of Special Design Telescopic Pipe

As a telescopic tube supporting the weight of the whole body, the importance is self-evident. It can adjust the height. Generally, the longest height is less than or equal to the length of 1/2 of the tube. For a single crutch like me, once it exceeds the height, the tube will break.

Replacement Selection of Spring Head (Marbles)

As the main culprit of most crutches re-purchased, the spring head is mainly used to adjust the height of the telescopic tube to make users more comfortable. During the friction process between the spring head and the tube hole, the wear and tear of the spring head will eventually break, and the user will fall and hurt his heel, the heavy one can not imagine.

Protective measures of crutches

When the spring head of the crutch is broken, insert the expansion tube into the adjusting gear, find the original hole, and select the right length screw nut for installation.
