Water circulation cooling blanket and control method thereof

Abstract

The invention provides a water circulation cooling blanket which comprises a blanket body, warm-keeping patches, a cooling water tank and a water pump, wherein the warm-keeping patches can be attachedto the inner layer of the blanket body and can protect the perineum, the abdomen and the heart of a patient; the cooling water tank communicates with a water inlet and a water outlet of a water circulation pipeline and can form a water flow loop with the water circulation pipeline; and the water pump is arranged in the cooling water tank and can pump water in the cooling water tank into the watercirculation pipeline. The water circulation cooling blanket can wrap a patient, the water circulation pipeline is arranged in the interlayer of the blanket body, cold water is pumped into the water circulation pipeline without manual intervention to achieve physical cooling, the water circulation cooling blanket is further provided with the warm-keeping patches capable of being attached to the inner layer of the blanket body, the perineum, the abdomen and the heart of the patient can be protected, and safe cooling is guaranteed. The invention further provides a control method of the water circulation cooling blanket.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a water circulation cooling blanket and a control method for the water circulation cooling blanket. Background technique [0002] Cooling is an important part of the treatment of heat stroke patients or patients with high temperature and fever. In addition to infusion of 4 ℃ normal saline, ice blanket, ice cap and CRRT, we also need to strengthen the use of physical cooling. Usually physical cooling uses Wipe the whole body with a wet towel, the water evaporates, and the heat on the body surface is taken away. However, this method requires the nursing staff to wipe the patient continuously, which is time-consuming and laborious. Therefore, there is an urgent need for a cooling device that can be wrapped on the patient without manual intervention to achieve cooling. [0003] The invention application document with the application number 201720010997.8 discloses a medical sleeping ...

[0002] Cooling is an important part of the treatment of heat stroke patients or patients with high temperature and fever. In addition to infusion of 4 ℃ normal saline, ice blanket, ice cap and CRRT, we also need to strengthen the use of physical cooling. Usually physical cooling uses Wipe the whole body with a wet towel, the water evaporates, and the heat on the body surface is taken away. However, this method requires the nurse to wipe the patient continuously, which is time-consuming and laborious. Therefore, there is an urgent need for a cooling device that can be wrapped on the patient's body to achieve cooling without manual intervention.

[0003] The invention application document with the application number 201720010997.8 discloses a medical sleeping bag that can realize physical cooling. A water-proof interlayer is installed in the sleeping bag, and cold water is pumped into the interlayer of the sleeping bag through the water circulation pipeline. However, this design is equivalent to putting the sleeping bag The overall design is a large water bag. When the patient is lying down, the sleeping bag is pressed against the bottom of the body, which hinders the flow of water and affects the cooling effect. The fully-wrapped sleeping bag covers the whole body, and physical cooling needs to avoid sensitive parts of the body for cooling. such as the perineum, abdomen, and heart

[0004] The invention application document with the application number 201721815743.X discloses a medical cooling blanket. Water pipes are installed in the interlayer of the blanket body. Although the problem that the cooling blanket is pressed against the bottom of the body, hindering the flow of water and affecting the cooling effect is solved, the cooling effect cannot be reduced. The problem that the blanket needs to avoid sensitive parts of the body for cooling has not been solved, and the safety during the physical cooling process cannot be guaranteed
