Description

Traction device for children

Technical Field

The utility model relates to the field of medical instruments, in particular to a traction device for children.

Background

Traction therapy is a method for applying external force to a certain part or joint of a body to separate the part or joint to a certain extent, and properly stretching surrounding soft tissues so as to achieve the aim of treatment. Traction therapy requires the use of traction devices. The traction device is often installed on a patient bed for use, and the structure of the traction device often comprises pulleys, traction ropes and weights. The traction rope bypasses the pulley, two ends of the traction rope are respectively connected with the traction part of the patient and the weight, the gravity of the weight is converted into traction force to carry out traction, and the weight is generally a weight.

The weight of traction should be adjusted according to the needs of illness, and can not be increased or decreased at will. The traction weight is too small. Is not beneficial to fracture reduction or deformity correction; excessive traction can cause excessive traction, resulting in soft tissue strain of the child, even fracture disunion. For children traction, the weight requirements are as follows: 1. the traction weight of the skin of the upper limb is usually 1/10 of the weight of the infant; traction of skin of lower limbs is 1/10-1/7; the weight of bone traction is generally 1/8-1/7 of the weight of the infant. The standard weight of male and female preschool children is 24Kg and 22.6Kg respectively, and is generally not more than 35Kg. The minimum traction weight adopted by the newborn can be as small as 0.1Kg, so that the traction weight of the preschool child ranges from 0.1Kg to 5Kg. The traction mode can be changed by adopting different weight weights, but after all, the number of the weights is limited, the traction is better and needs to be realized by combining weight weights with different weights, so that the traction mode is inconvenient and the traction is not easy to accurately adjust by a small amount. The traction force required by the traction of the children is small, the traction force difference required by different traction is also small, and the traction device which is convenient to adjust the traction force and convenient to adjust the traction force slightly can be used for the traction of the children.
