Description

Portable device for precise and rapid ice compress pressurization dosing

Technical Field

The invention relates to the technical field of medical equipment, in particular to a portable device for precise and rapid ice compress pressurization dosing.

Background

In clinical practice, after operation and sports sprain, PRICE is a basic means (PRICE: P protection, R rest, I ice compress, C pressurization and E elevation), has the functions of easing pain, reducing swelling and diminishing inflammation, and is a basic physical mode within 48 hours of tissue bleeding; currently, the well-recognized and indispensable method for treating acute injury and early pain and swelling after operation is recommended by clinical guidelines.

In clinic, the ice compress is mainly continuously applied within 24-48 hours after injury or operation (every 2 hours, the ice compress is 15 minutes, and the ice compress is stopped in the rest time, so that secondary vasodilatation reaction is avoided); or after functional training. The ice compress effect mainly stimulates a cold receptor, small blood vessels are immediately contracted through axonal reflection, the blood viscosity is increased, the blood flow speed is reduced, the tissue temperature is reduced, the hemostatic effect is achieved, the metabolic activity of cells and the damage of other tissues caused by cell hypoxia are further reduced, and the swelling is controlled; the speed of conduction of sensory nerves, especially the pain-sensitive fibrils, is reduced, the pain valve is raised, and the pain is relieved by blocking the conduction of pain impulses by a valve control mechanism.

The pressurization limits bleeding and swelling of tissues and plays a role in hemostasis by compression, particularly in places with many soft tissues and capsule masses, such as knee joints, ankle joints, radial joints and the like. Pressurization realizes full-period swelling stopping by reducing tissue gaps, limiting the volume of a sac cavity, and changing the pressure difference between tissue fluid and a circulatory system.

At present, medical staff usually adopt an ice bag or an ice bucket filled with ice blocks to ice the injured part of a patient, but the conventional ice compress mode has the defects that the comprehensive heat conductivity of a cold transfer path is smaller, air gaps exist on a contact interface (micro), the heat transfer efficiency is lower, and the actual skin ice compress normal temperature is not low enough; in addition, the heat release process of the ice blocks is not easy to control, and the temperature difference between the cold source and the surface is not controllable; the ice blocks are in a cold storage mode, the precooling period is long, hours are taken as a metering unit, and the ice blocks lack timeliness outdoors and in emergencies;

conventional bandage, gasbag, sand bag pressurization mode receive human structure and position influence, complex operation, and normal pressure to injured position ice compress is on the low side, and effective pressurization efficiency is on the low side, experiences and feels poor.

Influenced by independent icing and pressurization, the normal temperature and the pressure value of the conventional icing and pressurization carried out simultaneously often can not reach the ideal value, are uncontrollable, have poor experience feeling, often need professional operation, and the treatment effect is relatively poor. When the ice compress and the pressurization are used together, the treatment effect is poor.
