Problems solved by technology

[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

Embodiment 1

[0023] Such as Figure 1-2 As shown, a crutch with ventilation effect includes a support handle 1, a first cavity 2 is arranged inside the support handle 1, and a plurality of first air holes 3 communicating with the outside world are provided on the side wall of the first cavity 2 A plurality of first ventilation holes 3 are densely distributed in the middle and sparsely distributed on both sides on the support handle 1, so that the first ventilation holes 3 are concentrated directly below the patient's armpit to achieve a better ventilation effect, and both sides of the lower end of the support handle 1 are evenly distributed. A support block 33 is fixedly connected, the lower end surface of the support block 33 is provided with a groove 5, the first cavity 2 communicates with the groove 5 through a connecting pipe 6, and the lower end of the connecting pipe 6 is fixedly connected with a telescopic tube 7, which needs to be explained Yes, the telescopic tube 7 is made of a l...

Embodiment 2

[0030] Such as image 3As shown, in this embodiment, the communication mechanism includes a fourth cavity 25 arranged in the support seat 16, and the second exhaust end of the three-way valve 9 communicates with the fourth cavity 25 through the second exhaust pipe 26, The side wall of the fourth cavity 25 is provided with a second exhaust port 27, a one-way pressure valve 28 is installed in the second exhaust port 27, and the second exhaust port 27 passes through the third exhaust pipe 29 and the telescopic pipe 7. The side wall of the third exhaust pipe 29 communicates with the second cavity 14 .

[0031] In this embodiment, when the gas enters the fourth cavity 25 along the second exhaust pipe 26, under the action of the one-way pressure valve 28 and the first one-way valve 19, the gas is discharged in the fourth cavity 25 Collect and accumulate, as the air pressure increases slowly until it is greater than the critical value of the one-way pressure valve 28, the gas pushes...
