Analyzer for judging hordeolum swelling by pressure change value

Abstract

The present invention relates to an analyzer for judging needle hole swelling by pressure change value, comprising a limb fixing belt and a monitor, the monitor is arranged on the limb fixing belt, and the monitor includes a single-chip microcomputer, a pressure sensor, an input display module, a bee The buzzer and the system power supply module, the single-chip microcomputer is respectively connected with the pressure sensor, the input display module, the buzzer and the system power supply module, the pressure sensor is arranged on the limb fixing belt through the connection block, and the connection block is provided There is an air bag in close contact with the skin at the needle eye, the air bag is connected with the pressure sensor, one end of the limb fixing belt is fixedly connected with one end of the connecting block, and the other end of the connecting block is provided with a bayonet of the fixing belt. The pressure change value is measured by the pressure sensor, and the occurrence of swelling is judged, and the buzzer alarms.

Description

technical field [0001] The invention relates to an analyzer, in particular to an analyzer for judging needle hole swelling by pressure change value. Background technique [0002] One of the common complications of using IV catheters in newborns is fluid leakage leading to redness and swelling of the surrounding skin. Venous indwelling needles, also known as trocars, are widely used in clinics as replacement products for scalp needles because of their simple operation, soft cannula, long indwelling time in veins and difficulty in puncturing blood vessels. In recent years, the scope of clinical application of venous indwelling needles has continued to expand, especially in the rescue of critically ill patients and children's infusion. It can reduce the pain caused by repeated venipuncture in children and the fear of injections, and reduce the anxiety of parents. , Reduce the workload of nurses and reduce the pain of children. However, there are also some adverse effects duri...

Problems solved by technology

However, there are also some adverse effects during the application process. The most common is the leakage of liquid, which causes redness and swelling of the surrounding skin.

Those who need to use indwelling needles are generally those who need multiple injections or are hospitalized, and sometimes due to busy work, medical staff are not able to take care of them in time, and fluid leakage is prone to lead to redness and swelling of the surrounding skin
