A heat-insulating cold compress dressing pad

Abstract

The invention discloses a heat-insulating cold compress type dressing pad, which belongs to the technical field of cold compress for medical care. By adding a cooling valve and a flexible cold transfer sheet, when the dressing bag needs to be cooled, the semiconductor refrigeration sheet is used to cool the refrigeration bag column, and the outside world The air is introduced into the refrigeration capsule column through the air-introduction channel, and the air is cooled and introduced into the refrigeration chamber. On the one hand, the cold air is cold-transferred to the dressing bag through the cold-transfer flexible sheet, so that the temperature of the dressing bag is lowered, and it plays a role of cold compress. At the same time, the heat at the dressing bag is transferred outward through the cold delivery flexible sheet, and the flowing airflow improves the heat exchange effect. Both sides of the upper end simultaneously play a pressing role, which is beneficial to moderately compress the medicinal material in the dressing bag and effectively improve the dressing effect.

Description

technical field [0001] The invention relates to the technical field of cold compress for medical care, in particular to a heat-insulating cold compress dressing pad. Background technique [0002] At present, the method of external application of medicine is to spread the ointment on oily paper, textile gauze, etc., then apply it to the affected area, and then wrap it with a bandage. good environment. [0003] In order to improve the temperature of the affected part of the patient after trauma or surgery, it is traditional to wrap ice cubes with towels or gauze and place them on the parts that need cold compresses. By reducing the temperature of local tissues, local blood vessels can be shrunk, pain relieved, and inflammatory swelling reduced. Various effects, for acute trauma, local inflammation and other diseases, cold compresses are widely used. [0004] However, there are certain defects in the traditional simple cold compress method: firstly, the position of the cold c...

Problems solved by technology

[0004] However, there are certain defects in the traditional simple cold compress method: firstly, the position of the cold compress is not fixed, and it is easy to shift; secondly, ice cubes are wrapped in gauze for cold compress, and when exposed to the heat of the skin, it is easy to liquefy and stick to the skin, resulting in poor dressing effect.
