Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a medical cold compress bag.
Background
Cold compress is a medical treatment method, namely ice bags or cold wet towels are applied to the skin of the forehead, the back of the neck or the diseased region; the main purpose is to promote local vasoconstriction, control bleeding of small blood vessels and relieve pain of mass with large tension, so as to achieve the effects of relieving swelling and pain and improving discomfort.
Gout is a clinical syndrome caused by increased purine biosynthesis metabolism, excessive uric acid production or rise of uric acid in blood due to urinary excretion, precipitation of urate crystals in joint synovium, bursa, cartilage or other tissues, inflammatory reaction caused by external stimulation, and tissue damage. It is a group of heterogeneous diseases caused by the deposition of mono-natriuretic urate (MSU) crystals or uric acid in the extracellular fluid to form a supersaturated state. The initial clinical symptom of gout is acute gouty arthritis, which is manifested by acute single or multiple joint pain with sudden episodes during the night. With the improvement of the living standard of China and the change of the dietary structure and the living style, the gout incidence is rapidly increasing, and the pain is severe and attacks repeatedly, which has become a serious problem to bother gout patients. Gout does not directly endanger the life of a patient, but the pain during the onset, the damage to the body and the cost required for treatment all seriously affect the life and the work of the patient, and bring great economic and mental burden to the patient. Under the influence of external conditions, such as cold, drinking and the like, the common and applicable relieving method of acute gout joint pain is cold compress, the treatment of the cold compress is various, and many patients do not have a long waiting time for a long treatment process due to various reasons, such as work, life and the like.
Most of the existing cold compress is realized by pressing a bag filled with ice blocks and cold water close to the affected part or by adopting an antipyretic patch. Direct cold compress with bagged ice-cubes-disadvantage: the device is simple and crude, is not easy to fix the cold compress position, has hard texture, has small contact area with the ice compress part, and causes discomfort for patients. Although the problems of hardness, poor comfort and poor adhesion can be partially solved after the ice is crushed into crushed ice with small diameter, the ice often leaks after being slowly melted, and the injured part is infected, thereby affecting the health of the human body; the problem of water leakage can be solved by adopting the waterproof bag, but the temperature of ice in the cold compress bag is generally 0 ℃ or even lower, so that low-temperature frostbite can be caused to the skin, and secondary damage can be caused; in addition, the ice water bag is at 0 ℃ during use, and water in the air is condensed, so that the ice water bag is wet and brings discomfort during use.
The universal cooling patch or the cooling patch containing the medicinal components is used for cold compress, the fixation problem does not exist, but 1, the use loss is large, the effect of repeated use is difficult to achieve, the cost is high, and the economic burden is increased; 2. the cold compress effect is poor; 3. the appearance is single, is difficult to use to each aorta department ice compress of body, and bursts easily in the clinical use, makes the gel composition leak outward, causes environmental pollution.
