Problems solved by technology

[0002] Cesarean section is an important operation in the field of obstetrics. It can effectively deal with dystocia and pregnancy complications, and reduce perinatal mortality. However, the anesthesia method during the operation will dilate blood vessels, which will increase the heat loss in the spinal canal block, further Increased radiation heat loss of the patient's body, coupled with factors such as postpartum hemorrhage during the operation, long operation time, and the operating environment, often lead to hypothermia symptoms in the puerpera, and hypothermia increases the mortality and disability rate

Abstract

The invention relates to the technical field of medical instruments, and discloses an intraoperative limb heat preservation device which comprises a base layer. A supporting layer is fixedly mounted at the bottom of the base layer, and plastic packaging films are fixedly mounted at the bottom of the supporting layer and the top of the base layer. Two carbon nano tube heating elements are fixedly mounted between the base layer and the plastic packaging film on the upper side, copper electrodes with one ends extending to the outer side of the plastic packaging film are fixedly mounted at the two output ends of the two carbon nano tube heating elements, and electrode connecting wires are fixedly mounted on the outer sides of the four copper electrodes. According to the intraoperative limb heat preservation device, the problems that the existing common low-body-temperature recovery modes mainly comprise infusion heating, passive heating, active heating and the like, the modes are mainly achieved through heating devices such as metal resistance wires, direct contact between limbs and air is blocked to reduce the heat dissipating capacity, heat is supplied to maintain the core body temperature of a patient, however, the modes are slow in raising the temperature of the patient and poor in stability can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a limb heat preservation device during operation. Background technique [0002] Cesarean section is an important operation in the field of obstetrics. It can effectively deal with dystocia and pregnancy complications, and reduce perinatal mortality. However, the anesthesia method during the operation will dilate blood vessels, which will increase the heat loss in the spinal canal block, further Increased radiation heat loss of the patient's body, coupled with factors such as postpartum hemorrhage during the operation, long operation time, and the operating environment, often lead to hypothermia symptoms in the puerpera, and hypothermia increases the mortality and disability rate of the patient. Therefore, in cesarean section It is very necessary to increase heat preservation measures to prevent the occurrence of hypothermia in patients with massive bleeding. [0003] At ...
