Abstract

The invention discloses a cooling head sleeve carrying a microfluid flow channel, which comprises a head sleeve body and a microfluid flow channel, and is characterized in that the head sleeve body is used for coating the head of a patient suffering from fever, the microfluid flow channel attached to the inner wall of the head sleeve body is carried in the head sleeve body, and the microfluid flow channel can be tightly attached to the afterbrain part of a human body and is used for cooling the head; wherein the microfluid flow channel has a special geometric structure, the special geometric structure is a flow channel designed on the basis of distribution of blood vessels and nerves at the afterbrain part, the flow channel bypasses a local sensitive area of the afterbrain, one side of the flow channel is provided with a microfluid flow channel inlet, the other side of the flow channel is provided with a microfluid flow channel outlet, and a cooling solution with high specific heat capacity is injected into the microfluid flow channel. Therefore, the efficient heat absorption and cooling effects are achieved. The cooling head sleeve carrying the microfluid flow channel has the advantages of being low in cost, easy to machine, good in cooling and heat absorption effect and the like, and can meet the use requirement for assisting in physical cooling of the head of a patient suffering from fever.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to the structural design, preparation method and application of a cooling headgear equipped with a microfluidic flow channel. The cooling headgear equipped with a microfluidic flow channel can be used to assist in the physical cooling of the head of a febrile patient, in the field of adjuvant therapy. Background technique [0002] Fever as a disease has commonly appeared in daily life. Most fevers are caused by infections, such as pathogenic microorganisms such as viruses, bacteria, and parasites. There are also some non-infectious fevers that manifest as complications of some diseases, such as endocrine and metabolic diseases, tumor fever caused by malignant tumors, organic diseases, tuberculosis, etc. Under normal circumstances, the body's thermoregulatory center regulates the dynamic balance of the body's heat production and heat dissipation process. When the body is infected wit...
