Automatic pulse cold compressing system and cold compressing method

Abstract

The invention discloses an automatic pulse cold compressing system, including an air refrigerating unit in which an evaporator is arranged in a large water tank, and also including a circulating path composed of a small water tank, a membrane pump, an ice bag and the large water tank; a central processing unit, which is electrically connected with the compressor of the air refrigerating unit and a first temperature sensor respectively. The central processing unit collects the value of the first temperature sensor, and controls the compressor according to the collected temperature value; meanwhile, the central processing unit outputs PWM waves to a pulse control circuit which outputs adjustable voltage to the membrane pump according to the PWM waves, so that the rotation speed of the membrane pump changes and outputs water with different pressure into the ice bag. The cold compressing method includes the steps that: the compressor refrigerates and cools water in the large water tank, the membrane pump pumps the water into the ice bag, and thereby cold compress therapy to an infected part is achieved. Meanwhile, the membrane pump of the invention also can output the water with different pressures into the ice bag, thus also achieving massage to the infected part, and further increasing the cold compressing effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic pulse cold compress system and a cold compress method. Background technique [0002] Cold compress method is one of the treatment methods. Most of the cold compress treatment methods currently used are: apply ice packs or cold wet towels to the lesion, the main purpose is to promote local vasoconstriction, control the bleeding of small blood vessels and relieve the pain of large tension masses. Achieve the effect of reducing swelling and relieving pain; for patients with high fever, apply it on the forehead and back of the neck to reduce body temperature and improve discomfort. Especially in hospitals, cold compress is an important measure for clinical treatment and nursing of patients with high temperature. However, cold water and ice cold compresses cannot control the temperature of the cold source, and will also soak other supplies, which brings great harm...
