Problems solved by technology

[0003] Since extracorporeal membrane oxygenation (ECMO) evolved from extracorporeal circulation in cardiac surgery, hyperthermia of core body temperature usually does not exist during extracorporeal circulation. The role of blood warming, for patients with new coronary pneumonia, fever is one of the symptoms, therefore, when the existing ECMO is applied to the treatment of patients with infectious disea

Example Embodiment

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] Since the existing in vitro-vital membrane lung oxygenation (ECMO) is mainly used in severe patients in cardiopulmonary failure, the emergency patient is in a lower metabolic state, so the existing ECMO has only heating function, does not have cooling function, in the application In the treatment of patients with cardiopulmonary disease with fever conditions, there is no problem to cool down as needed.

[0035] In order to solve the above technical problems, such as figure 1 As shown, a structural diagram of the temperature control system for CDMO for cardiopulmonary failure is given, and the ECMO is composed of power pump 1, an oxygenator 2, a blood flow pipe 3, and a blood return pipe 4. The pump 1 is used to simulate artificial heart, and the oxygenator 2 is used to simulate artificial pulmonary, the inlet of the power pump 1 is in communication with the blood flow pi

Abstract

The invention provides a temperature control system of ECMO for cardiopulmonary failure treatment, which comprises a power pump, an oxygenator, a blood outflow pipe and a blood return pipe, a temperature management device is composed of a shell, a water tank, a circulating pump, a cooling fan, a heating resistance wire and a control circuit, a cooling device is the cooling fan or a compression refrigerating machine, a water outlet of the water tank is communicated with a water inlet of the oxygenator through a circulating pump and a water supply pipe in sequence; a first temperature sensor is arranged on the blood outflow pipe, and a fifth temperature sensor and a sixth temperature sensor are arranged on the water supply pipe and a water return pipe which are connected with the water tank respectively. According to the temperature control system and method, the technical problem that an existing ECMO system can only heat up but not cool down and cannot perform accurate body temperature management is solved, the risk of frostbite caused by in-vitro cooling of an ice blanket and an ice cap is avoided, and necessary premise and technical support are provided for long-term treatment of cardiopulmonary failure.
