Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a medical limb warming and insulation device. Background Technology

[0002] Currently, in hospitals, patients need to maintain a certain body temperature during or after surgery, depending on the type of surgery. Generally, the patient's body temperature needs to be controlled at around 37 degrees Celsius.

[0003] For example, Chinese utility model patent CN214318274U proposes a medical limb warming and keeping device, including a heating device that provides hot air to the left hand, right hand, left foot, and right foot covers via a first, second, third, and fourth air outlet pipe, respectively. The heating device generates hot air at a specific temperature, which is then worn on the patient's left hand, right hand, left foot, and right foot (i.e., on their limbs). A skin temperature probe within the heating device detects the patient's current skin temperature, preventing excessive heat or burns. When a limb requires warmth, the corresponding air outlet pipe is activated, delivering the hot air to that limb; other limbs do not require heating, allowing patients to choose which area to heat. Therefore, this invention, by providing left hand, right hand, left foot, and right foot protectors corresponding to the four limbs of the human body, can selectively provide hot air to the patient's limbs, thereby controlling the body temperature of the corresponding limbs within a preset temperature range and improving user comfort. Furthermore, since the left hand, right hand, left foot, and right foot protectors are directly applied to the patient's limbs and can be easily removed when not in use, their temperature regulation effect is far superior to traditional heated blankets, heated sheets, and heating pads.

[0004] In existing technologies, heat preservation is achieved by using air heating. This requires continuously heating the air, which consumes a lot of energy. Furthermore, the warm air is directly dissipated to the outside after use, resulting in a waste of heat. Utility Model Content

[0038] In related technologies, the use of air heating for heat preservation requires the continuous heating of air, which consumes a lot of energy. Furthermore, the warm air is directly dissipated to the outside after use, resulting in a waste of heat.

[0039] To address some of the problems in related technologies, this application provides a medical limb warming and insulation device. By setting up a heat supply component, which is connected to the suction and inlet pipes of the upper and lower limb sleeves via a liquid extraction component and a circulating liquid inlet component, the device provides warmth by heating the water via the heat supply component. The heated water is then continuously pumped into the upper and lower limb sleeves through the suction and inlet pipes. Compared to air heating, water heating reduces energy consumption and improves comfort, avoiding the waste of warm air and preventing the constant blowing of warm air onto the limbs, which can cause dry and cracked skin.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] Combination Figures 1-5 This application provides a medical limb warming and heat preservation device, including an upper limb sheath 10 and a lower limb sheath 20.
