Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0043] The ECMO heat exchange water tank used clinically in the prior art solution is automatically cooled at room temperature and has no active cooling function. Therefore, the present invention provides a heat exchange water tank capable of active cooling.

[0044] figure 1 A frame of a heat exchange water tank according to an embodiment of the present invention is shown.

[0045] Such as figure 1 As shown, the heat ...

Abstract

The invention discloses a heat exchange water tank and a temperature control method. The temperature control method comprises the steps that the real-time temperature of liquid in a liquid storage tank is obtained according to a temperature sensor; the temperature difference value between the real-time temperature and the set temperature of the heat exchange water tank is calculated through the controller, and the heating or refrigerating current value of the heat exchange assembly is calculated according to the temperature difference value; an inner circulation pipeline is started, and heat convection is conducted on liquid in the liquid storage tank through the heat exchange assembly; and the external circulation pipeline is started to realize heat exchange between the liquid in the liquid storage tank and external equipment. According to the heat exchange water tank, the semiconductor refrigeration principle is utilized, temperature adjustment within the range of 15-39 DEG C is achieved, and the temperature adjustment time is shortened; and meanwhile, high-precision temperature control is achieved by combining a PID temperature control method, the method is suitable for the extracorporeal membrane oxygenation system, and the requirement for refrigeration of medical equipment during cardiac surgery is met.

Description

technical field [0001] The invention relates to the field of development of an extracorporeal membrane oxygenation system, in particular to a heat exchange water tank and a temperature control method thereof. Background technique [0002] Extracorporeal membrane lung is an important means to treat respiratory failure. Extracorporeal Membrane Oxygenation (ECMO) represents the advanced technology in the field of extracorporeal circulation, and the oxygenator (membrane lung) is the key core device in the ECMO system, and its main function is to exchange blood oxygen and remove carbon dioxide. [0003] The ECMO heat exchange water tank currently used in clinical practice does not have both the ability to heat up and cool down, that is, it cannot provide a stable temperature for the extracorporeal membrane oxygenator within a certain temperature range. Contents of the invention [0004] The purpose of the present invention is to provide a heat exchange water tank that provides...
