Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an external cooling sleeve. Background Technique

[0002] After cerebral hemorrhage, patients often have fever symptoms, which may be caused by various factors such as absorption fever, infection, and central hyperthermia caused by bleeding. High fever not only increases the metabolic burden of patients, but may also exacerbate brain tissue damage and affect the recovery of the disease. Therefore, effective cooling care for cerebral hemorrhage patients is particularly important. In the past, traditional physical cooling methods such as applying ice cubes and wearing ice caps were often used for patients with high fever in clinical practice. Although these methods can reduce body temperature to a certain extent, they have disadvantages such as cumbersome operation, unstable cooling effect, and easy local frostbite. Especially for comatose patients with cerebral hemorrhage, traditional cooling methods often fail to achieve the ideal cooling effect. In summary, the external cooling sleeve, as a new emerging cooling care method, has broad application prospects and research value.

[0003] Chinese Patent Publication No. CN214342887U discloses a cooling cap for patients with cerebral hemorrhage. A cooling cap for patients with cerebral hemorrhage includes a cap body, a water tank, and a cooling mechanism. The cooling mechanism includes a micro water pump, a water supply pipe, and a water return pipe. The micro water pump is fixed on the inner wall of the water tank. The micro water pump is externally connected with a power supply device. The inner wall of the water tank is communicated with a water supply pipe. The water supply pipe and the water return pipe are respectively communicated with the water tank. The water supply pipe is connected to the water outlet end of the micro water pump. A heat dissipation pipe is arranged on the cap body. Both ends of the heat dissipation pipe are respectively communicated with the water supply pipe and the water return pipe. This cooling cap for patients with cerebral hemorrhage, through the combination of structures such as the water supply pipe, the return pipe, the water inlet head, the water outlet head, and the heat dissipation pipe, takes away the temperature of the patient's head through the circulating flow of liquid water, reduces the heat in the skull, and thus reduces the patient's blood pressure.

[0034] First, the outer coat 1 covers the part of the patient that needs to be cooled, and is adjusted to the accurate position by sliding the sliding sleeve 3. Then, according to the patient's body type, the tightness is adjusted through the buckle 9 and the snap fastener 10 on the strap 2. Then, the storage battery 14 is started to supply power to the semiconductor refrigeration sheet 13 to make it start working, and heat is dissipated through the ventilation opening 12 of the sliding sleeve 3. Finally, if it is necessary to increase the pressure to promote blood circulation or relieve pain, the core cap 18 can be opened, and air is inflated into the airbag 5 through the inflation valve 17. After adjusting to the appropriate pressure, the core cap 18 is re-closed.
