example 1

[0067] In the table below an example of information related to the correct decision of the control unit that the patient is in a trembling state is shown. For the sake of simplicity, this example only concerns one cooling circuit comprising only one distribution device. However, within the scope defined here, it is also possible to have more than one cooling circuit and / or more than one distribution device. In this example, the fluid temperature in the fluid supply is set to -7°C.

[0068]

[0069]As can be seen from the table, during the first 100 minutes, no indication of shivering was apparent. After 100 minutes of cooling therapy, the patient's core temperature had dropped from 37°C to 35.5°C, and the return flow temperature stabilized at about -4.9°C. After 120 minutes had elapsed from the start of treatment, the situation had changed. Now the return temperature has risen to -1°C, which leads to a significant increase in power consumption. Based on this information...

example 2

[0071] Shivering can be detected based on monitoring different control process parameters according to the stage of the cooling process. Such as image 3 As shown, the cooling process can be divided into three main stages: a first stage S1, wherein in the first stage S1, the body temperature is lowered from normal body temperature to a specific reduced body temperature; a second stage S2, in which in the second stage S2 During this period, the body temperature is maintained at a specified reduced core body temperature; and a third stage or rewarming stage S3, wherein in the third stage, the body temperature is raised from the specified reduced body temperature to normal body temperature. image 3 The solid line curve for core body temperature shown generally represents the appearance of common hypotherapeutic cooling treatments. The reference curve represented by the dashed line is used as the target temperature for the medical cooling device. In well known systems, the medi...

Abstract

A medical cooling device for reducing the body core temperature of a patient and a method for operating the same are provided. The cooling process provided by the medical cooling device is based on the state or degree of shivering of the patient.

Description

technical field [0001] The present invention relates to medical cooling devices and methods for reducing the body core temperature of a patient by medically cooling the patient's body parts, and in particular the patient's brain, in a non-invasive manner. [0002] Cross References to Related Applications [0003] Filed October 15, 2015 titled "Device And Method For Reducing The BodyCore Temperature Of A Patient For Hypothermia Treatment By Cooling At LeastTwo Body Parts Of The Patient" and requests SE 1451236-2 filed October 15, 2014 The entire content of the priority co-pending international application PCT / EP2015 / 073910 is incorporated by reference. Background technique [0004] Targeted medical cooling of body parts to lower the body's core temperature for hypothermia is a useful tool for mitigating adverse effects of body parts under specific conditions. For example, medical cooling can be used to cool the brains of patients suffering from strokes. By lowering the tem...
