Description

Limb fixer for arteriovenous puncture of children

Technical Field

The utility model relates to a clinical care equipment technical field especially relates to a children artery and vein puncture limbs fixer.

Background

In the pediatric clinical arteriovenous puncture process, because the infant is small in age, poor in matching degree and not easy to fix due to the fact that the arm shakes, a nurse hardly masters the needle insertion angle, the puncture success rate is low, the pain of the infant is increased, and the workload of the nurse is increased. In the prior art, researches on related fixing devices for arteriovenous puncture of a child patient are few, and certain limitations exist.

The main drawbacks are as follows: 1. the limb placing table is horizontal, blood is easy to flow back during venipuncture, blood vessels cannot keep a full state, and meanwhile, the comfort level of a child patient is reduced; 2. the wrist support design is not adopted during radial artery puncture, so that a nurse is difficult to master the bending degree of the wrist joint of the child patient, and the puncture success rate is reduced; 3. the radial artery puncture locator is lacked, and nurses often perform puncture location by virtue of working experience, so that the scientificity is lacked; 4. the restraint device is lacked, the palm of the infant patient can move in a non-directional manner during puncturing, the success rate of puncturing is reduced, and even the infant patient who is not in cooperation with the operation can scratch the puncturing person; 5. the prior art can only be used for simple artery or venipuncture fixing, and the problem that radial artery and upper limb venipuncture of a child patient are difficult to fix can be solved simultaneously without a fixing device.
