Title:
COOLING HEAD SLEEVE EQUIPPED WITH MICROFLUID FLOW CHANNEL
Document Type and Number:
WIPO Patent Application WO/2022/127618
Kind Code:
A1
Abstract:
A cooling head sleeve equipped with a microfluid flow channel (4), comprising a head sleeve body (1) and a microfluid flow channel (4). The head sleeve body (1) is configured to coat the head of a patient suffering from fever. The head sleeve body (1) is equipped with the microfluid flow channel (4) attached to the inner wall of the head sleeve body (1). The microfluid flow channel (4) can be tightly attached to the afterbrain part of a human body and is used for cooling the head. The microfluid flow channel (4) 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, and 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 (5), and the other side of the flow channel is provided with a microfluid flow channel outlet (6). A cooling solution with high specific heat capacity is injected into the microfluid flow channel (4). Therefore, the efficient heat absorption and cooling effects are achieved. The cooling head sleeve equipped with the microfluid flow channel (4) has the advantages of low cost, simple processing, and good cooling and heat absorption effect, and can meet the use requirements for assisting in physical cooling of the head of a patient suffering from fever.
