Description

Energy-saving medical temperature control instrument

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a medical accuse temperature appearance of energy-saving.

Background

Medical temperature control instruments are commonly used to regulate the temperature of an external circulation line (e.g., an external water blanket) to meet the needs of a user. When the external water blanket is an external circulation pipeline, the external water blanket can be divided into a blanket, a cap, an elbow sleeve, an ankle sleeve, a waist sleeve, a shoulder sleeve and the like according to different body parts, and the capacity of each external circulation pipeline is different. In the conventional medical temperature controller, an evaporator or a heater is generally arranged in a water tank, liquid in the water tank is cooled or heated to a set temperature, and the liquid in the water tank is circularly conveyed in the water tank and an external circulating pipeline, so that the liquid circulation and the temperature control of the medical temperature controller are realized.

The design method has the disadvantages of energy waste and inconvenience in maintenance. Wherein, the energy waste is that: 1. the variety, single capacity and use number of the external circulation pipelines are different, so that the actually required circulation liquid capacity of the medical temperature controller is uncertain in actual operation. Therefore, aiming at the existing medical temperature control instrument, enough liquid can be added into the water tank only so as to ensure the liquid using requirements for connecting different external water blankets. The preset liquid amount in the water tank exceeds the actual liquid consumption amount, and the heating and cooling of the exceeding part of liquid consumes energy, thereby forming energy waste. 2. The evaporator and the heater are arranged in the water tank, the liquid level in the water tank must cover the evaporator and the heater, and the liquid volume is present so that the evaporator does not frost and the heater does not dry out in the actual operation of the temperature controller. The liquid in the part of the volume also needs to be heated and cooled as the liquid participating in circulation, energy is consumed, and energy waste is also formed. 3. The compressors used by the existing medical temperature control instruments are all alternating-current compressors, the rotating speed is fixed, and the refrigerating output can not be adjusted under the standard working condition. The refrigeration is stopped when reaching the set temperature, and the refrigeration is started after deviating from the set temperature, so that the temperature fluctuation of the controlled liquid is large, the control is difficult, the start and the stop are frequent, and the energy waste exists. Secondly, the maintenance is inconvenient in that: 1. the evaporator and the heater are arranged inside the water tank, so that the maintenance is inconvenient. 2. The alternating-current compressor is large in size, and a refrigeration assembly formed by the alternating-current compressor and the water tank evaporator is large in size, inconvenient to assemble and disassemble and difficult to maintain.
