Description

Multi-plug-in hypothermia therapeutic instrument

Technical field

The invention relates to the technical field of medical devices, and in particular to a multi-plug-in sub-hypothermic treatment instrument.

Background technique

With more and more high-quality research evidence in recent years, mild hypothermia treatment can reduce the mortality of newborns with HIE (hypoxic-ischemic encephalopathy) and the incidence of severe disability at 18 months. The Ministry of Health also issued a protocol for the treatment of neonatal HIE with mild hypothermia in 2011, which set an overall standard for HIE treatment. Foreign research on the treatment of neonatal hypothermia started earlier than in China, and many clinical research centers have also confirmed that hypothermia treatment can improve the prognosis of neonatal HIE. In the treatment of neonatal HIE, it is necessary to pay attention to the physiological parameters of the newborn in real time, such as ECG, blood oxygen, blood pressure, amplitude EEG, especially EEG parameters in the pre-treatment screening of the condition, real-time monitoring during treatment, and prognosis after treatment. Played an important role. The neonatal hypothermia treatment program has different characteristics from adults, so there is an increasing need for a hypothermia treatment instrument dedicated to neonatal departments.

technical problem

Traditional sub-low temperature therapeutic equipment usually includes heating/cooling system, water circulation system, temperature detection system, and host display control system. If the patient's physiological parameters such as ECG, blood oxygen, blood pressure, and EEG parameters need to be monitored during the treatment process, additional instruments need to be connected, which results in complicated operations, confusion, and low efficiency in the treatment process. One solution is to integrate part of the physiological parameters into the system, which is not disassembled as a whole with the system. This method has high cost and poor flexibility.

The water circulation system generally consists of a water tank, a water pump, and pipes connected to it. The general water circulation system includes two cycles: cold water cycle and mixed water cycle; cold water cycle requires a cold water tank and pump for the cooling treatment process; mixed water cycle is a mixed water cycle after cold water and hot water are mixed, and requires a mixed water tank and pump; so Adopting this method requires two water tanks and two water pumps, with complex structure, high noise and large volume of the whole machine.

During sub-hypothermia treatment, there is a risk of clogging or leakage of pipelines and water blankets (caps) in the water circulation system. Once such risks occur, the treatment may be interrupted or the treatment effect may be poor, or even the machine may be damaged. The machines on the market basically ignore such problems, and there is no good solution.

The temperature detection system detects the patient's body temperature and water temperature, and controls the water temperature through body temperature feedback. The circulating water transfers heat to the patient through the water blanket, thereby changing the patient's body temperature. During the heating or cooling process, the water temperature should be kept within a safe range (generally 4°C-42°C). If it exceeds the range, it may cause frostbite or burns. In the case of a single fault failure, the temperature sensor of the traditional hypothermia treatment device lacks multiple protection mechanisms, and the water temperature may exceed the limit value.

There are currently two types of refrigeration technologies used in heating/refrigeration systems, one is the use of compressor refrigerants for refrigeration, and the other is the use of semiconductor refrigeration chips for electronic refrigeration. The use of compressors for refrigeration is noisy and the machine is large, which is an obvious disadvantage for the NICU department with harsh noise requirements.

At present, most of the hypothermia treatment devices used in the neonatal department are directly used in the adult department after minor changes, and some are even used without modification, which cannot truly meet the specific needs of the neonatal department, so for HIE disease The treatment of hypothermia requires more professional equipment.

Therefore, how to improve the therapeutic performance of the hypothermia therapeutic apparatus has become an urgent technical problem to be solved.

Based on this, the present invention discloses a multi-plug-in mild hypothermia treatment instrument, which improves the treatment performance of the hypothermia treatment instrument by solving the above-mentioned technical problems.
