Abstract: The present disclosure provides a device and a method for cooling living tissues for a medical purpose and other purposes. The cooling device includes a cooling medium contacting the living tissues to be cooled. The cooling medium comprises: a first fluid medicine reservoir configured to be installed outside a main body that couples with a medical cooling device and to move into the main body, wherein the first fluid medicine reservoir stores a first fluid medicine to be injected through a hole at a tip of the main body.

Abstract: The present disclosure provides a device and a method for cooling living tissues for a medical purpose and other purposes. The cooling device comprises: a container configured to accommodate a cooling medium, the container including a plurality of divided members each having a contact surface which is thermally coupled with the cooling medium; a cooling generator configured to provide cooling energy to the container, and disposed on another surface of the divided member other than the contact surface; and a lubricating member provided to the contact surface of the divided member, wherein the container is configured to be thermally coupled with the cooling medium via the lubricating member.

Abstract: The present disclosure provides a device and a method for cooling living tissues for a medical purpose and other purposes. The cooling device comprises: a container configured to accommodate a cooling medium and thermally coupled with the cooling medium by directly contacting the cooling medium; a cooling generator configured to be thermally coupled with the container by a direct contact and thereby to provide cooling energy to the cooling medium; and a heat sink dissipating heat from the cooling generator, the heat sing being configured to be spaced apart from the cooling generator and to be thermally coupled with the cooling generator without a direct contact with the cooling generator.

Abstract: The present disclosure provides a device for cooling a living tissue that solves severe patient's waiting and clinic work load due to time-consuming anesthesia required by conventional therapies and significantly reduces psychological burden and pain of the patient for ocular anesthesia.
