Walking stick with ventilation effect

Abstract

The invention belongs to the field of medical treatment and especially relates to a walking stick with a ventilation effect. The walking stick comprises a supporting handle, wherein a first cavity isformed in the supporting handle, a plurality of first ventilation holes communicated with the outside are formed in a lateral wall of the first cavity, supporting blocks are fixedly connected to the two sides of the lower end of the supporting handle, grooves are formed in lower end faces of the supporting blocks, the first cavity is communicated with the grooves through connection pipes, telescopic pipes are fixedly connected to the lower ends of the connection pipes, supporting rods are arranged in the grooves, the lower ends of the telescopic pipes are fixedly connected with the upper endsof the supporting rods, three-way valves are arranged in the supporting rods, first air exhaust ends of the three-way valves are communicated with the grooves through first air exhaust channels, firstair exhaust openings are arranged on lateral walls of the grooves, control valves are arranged in the first air exhaust openings, a holding handle is fixedly connected between the two supporting rods, and a second cavity is formed in the holding handle. The walking stick disclosed by the invention not only has better ventilation and reduces patient pain, but also is convenient to use; furthermore, the length of the walking stick is convenient to adjust.

Description

technical field [0001] The invention belongs to the medical field, in particular to a crutch with ventilation effect. Background technique [0002] Crutches are a support device that can assist patients with mobility issues to move. The existing crutches are relatively simple in structure and generally consist of two support parts, one is to support the armpit and the other is to support the grip of the arm. Because when the patient uses the crutches, a considerable part of the weight of the body will be pressed on the crutches, resulting in a very close contact between the patient's body and the supporting parts of the crutches. The patient's palms and underarms, especially the underarms, are always in close contact with the crutches. , over time, it is easy to cause the patient's skin to fester and bring greater pain to the patient; in addition, the common crutches on the market generally have a telescopic function in order to be easy to carry (for example, put in a car), ...

[0002] Crutches are a support device that can assist patients with mobility issues to move. The existing crutches are relatively simple in structure and generally consist of two support parts, one is to support the armpit and the other is to support the grip of the arm. Because when the patient uses the crutches, a considerable part of the weight of the body will be pressed on the crutches, resulting in a very close contact between the patient's body and the supporting parts of the crutches. The patient's palms and underarms, especially the underarms, are always in close contact with the crutches. , over time, it is easy to cause the patient's skin to fester and bring greater pain to the patient; in addition, the common crutches on the market generally have a telescopic function in order to be easy to carry (for example, put in a car), while the existing telescopic The crutches generally realize the telescopic function through mechanical parts, so that the adjustment process of the existing crutches is not only cumbersome, it is difficult for the patient to complete independently, but also because there are more mechanical parts, the weight of the crutches is increased. In order to ensure the portability of the crutches , only more expensive lightweight materials can be used, increasing the cost
