Abstract
A medical cooling device comprises an air pressure device, a liquid nitrogen container, a liquid nitrogen conduit, a cooling head, a temperature setting device, a temperature sensor and a controller, wherein the air pressure device is communicated with the liquid nitrogen controller, one end of the liquid nitrogen conduit is communicated with the liquid nitrogen container, and the other end of the liquid nitrogen conduit is communicated with the cooling head. The temperature sensor is arranged inside the cooling head and used for detecting temperature of the cooling head and transmitting temperature signals to the controller, the temperature setting device is used for presetting the temperature required by the cooling head, and when the temperature displayed by the temperature signals received by the controller is lower than the preset temperature, the controller controls a resistance wire in the cooling head to work so as to lead the temperature to rise to the preset temperature. The cooling device can fast reduce local temperature of patients, is particularly suitable for reducing temperature of heart areas of patients when acute myocardial infarction attacks, is expected to fast reduce local temperature of patients, and achieves the aim of easing pain of the patients, relieving over-fast heartbeat and gaining time for operation rescue.
Description
Technical field
This utility model belongs to the cooling system field, particularly a kind of medical cooling system.
Background technology
(acute myocardial infarction AMI) is acute myocardial infarction again, is meant because of the cardiac muscle of the part due to lasting and serious myocardial ischemia acute necrosis in acute myocardial infarction.Clinical manifestation has an intense pain after persistent breastbone is often arranged, rising and the myocardium acute injury and downright bad carrying out property of electrocardiogram differentiation of acute circulatory function obstacle, arrhythmia, heart failure, heating, numeration of leukocyte and serum myocardial damage marker enzyme.General Symptoms in the pathogenic process mainly is heating, increases with erythrocyte sedimentation rate with tachycardia, leukocyte to speed etc., because downright bad material absorbing causes.Body temperature is generally about in the of 38 ℃, the sustainable long period.Generally speaking, when the patient fell ill at home, if can make patient temperature apace, especially the chest temperature was reduced to normal body temperature; Or even be lower than normal body temperature, and both possibly alleviate patient's pain, slow down tachycardia; Can seek medical advice for delivering to hospital again, operative treatment gains time, and saves patient's life.
In clinical, generally adopt two kinds of methods of Physical temperature-lowering and chemicals cooling to reach the purpose that reduces body temperature to the patient.Chemicals cooling mainly is to adopt oral or inject corresponding medicine and realize, but this method cooling rate is slow, the time long (about 30 minutes), and be only applicable to the cooling of patient's bulk temperature, can not realize the local or focus zone cooling of patient.The physical cooling method simple, intuitive mainly is to adopt cold-producing medium (piece) directly is placed on the patient body somewhere, reaches local cooling and then realizes whole purpose of lowering the temperature.The Physical temperature-lowering curative effect reliably, safely, have no side effect, applied range.Its simple and direct way places ice bag to obtain cool effect for exactly the patient body somewhere; Clinical proof; Advantage is that the patient shiver with cold seldom occurs, generally body temperature reduced to below 30 ℃, but shortcoming is also apparent in view, and is slow like cooling rate, the cooling-down effect that is used to be grown up is poor.In order to overcome these shortcomings of direct ice compress, domestic-developed several kinds of physical hypothermal devices, the Medical Refrigerating Instruments (being mainly hypothermic blanket) that proposes like people such as Fan Xiang virtue in 2002; Primary structure is made up of refrigeration system, blood circulation, control system and hypothermic blanket, and blanket face minimum temperature is no more than 8 ℃, and unloaded temperature fall time is no more than 15 minutes; Through the clinical development good refrigeration effect; But this system structure is complicated, and refrigeration system comprises that compressor etc. is difficult to move, and is not suitable for standing at home.Need wear the 3-4 layer to medical personnel in the SARS virus isolation area in 2003 for another example isolates clothes, layer 2-3 medicated cap, the mask more than 12 layers, rubber gloves and causes the phenomenon that medical personnel suffer heatstroke and fall in a swoon with the good plastic goggles of face driving fit all around; Open third of the twelve Earthly Branches equality people and develop the medical cooling clothes of a cover; This device can be good at reducing medical personnel's whole body temperature, but this device can not be applicable to local cooling.The Luo Hui tinkling of pieces of jade in 2009 propose the development thinking of combined type medical cooling hat; Although obtained some good effects clinically; But because it does not have the intelligent temperature control design; Can not change temperature according to patient's needs, and it is bigger influenced by patient self body temperature, hospital environment temperature etc., is difficult to realize extensive clinical practice.Liquid nitrogen has in medical science widely to be used, common as cleaning and sterilization etc.The earliest calendar year 2001, domestic scholars Li Yong proposes to adopt liquid nitrogen to make medical sleeping bag to satisfy the function to patient's Physical temperature-lowering.This system has rapid cooling and advantages of simple operation, but bulky, is difficult to be applicable to local cooling, is not suitable for domestic environment.In sum, Physical temperature-lowering safely, have no side effect, can realize local cooling and become the common means that medical institutions realize patient's cooling.And existing physical hypothermal device, comprise that also the simplest ice compress cooling, the problem that all exists some to be difficult to overcome,, system complex wayward like cooling rate are difficult to carry or are difficult to realize problem such as local cooling certainly.
The utility model content
In order to solve the defective that being difficult to of existing in the above-mentioned existing cooling system realize that local cooling, cooling rate are slow, do not have intelligent temperature control, the purpose of this utility model be to provide a kind of very convenient, be easy at home and the fast medical heat sink of cooling rate.
In order to achieve the above object; This utility model adopts following technical scheme: a kind of medical cooling system, comprise pneumatic shuttle, liquid nitrogen container, liquid nitrogen conduit, cold head, temperature setting device, temperature sensor and controller, and said pneumatic shuttle is connected with said liquid nitrogen container; Said liquid nitrogen conduit one end is connected with said liquid nitrogen container; The liquid nitrogen conduit other end is connected with said cold head, and it is inner that said temperature sensor is positioned at said cold head, is used to detect the temperature of said cold head; And temperature signal passed to said controller; Said temperature setting device is used for the temperature of preset said cold head needs, and the temperature signal temperature displayed that receives when said controller is lower than preset temperature, and then the resistance wire work controlled in the said cold head of controller makes the temperature rising reach preset temperature.
Preferably, said cooling system also comprises alarm, and said alarm is connected with said cold head, is used for temperature and crosses warning when hanging down.
Preferably, said cold head is made up of close skin material and porous copper product.
Preferably, said temperature sensor uniform distribution in said cold head.
Preferably, said pneumatic shuttle is foot-operated pneumatic shuttle.
The beneficial effect of this utility model: the cooling system in this utility model can reduce patient's local temperature rapidly; The reduction of heart area temperature when being particularly useful for the Acute Myocardial Infarction Patients morbidity; Be expected to reduce rapidly patient's local temperature; Reach and alleviate patient's slight illness, alleviate tachycardia, save the purpose that gains time for operation.
