Description
Technical field
The present invention relates to blood purification and Multi-organ systems life support technology, particularly relate to a kind of self-balance displacement apparatus supported for multiple organ.
Background technology
War, the perils of the sea, earthquake and various natural disaster cause a large amount of injury to personnel, and damage is extensive, traumatic condition is complicated, seriously injured, and then multiple organ dysfunction syndrome appears in rapid progression, causes mortality rate obviously to increase.In addition away from hospital, can not in time after give, must give treatment at the scene.Therefore, early stage Multi-organ systems life support treatment is carried out to save life at a line to these severely injured personnel, significant.
Multi-organ systems life support treatment comprises: continuous blood purification renal function substitutes, oxygenation (mould lung) respiratory function support and artificial liver support system etc.Conventional multiple organ supportive device is integrated with the modules such as artificial kidney, artificial liver, artificial lung more, wherein artificial kidney and artificial liver function all adopt blood purification technology to realize, and artificial lung many employings membrane lung technology realizes, membrane lung module is by being aided with the function that oxygen circuit can realize oxygenation in doughnut device serial or parallel connection to blood circuit, the basis of blood purification circuit only needs add pressure monitoring, therefore do not need to configure more equipment on device.And artificial kidney and artificial liver function are all realized by blood purification technology, therefore the function body of multiple organ supportive device is apparatus for purifying blood, and the type selecting of apparatus for purifying blood and implementation determine the main feature of multiple organ supportive device.
Apparatus for purifying blood, according to the filter of apolegamy during treatment and device drive manner, can realize the treatment to kidney and liver, substitutes and support.Blood purification partial devices accounts for the overwhelming majority of whole machine.Fluid infusion and the ultrafiltrate path driving device of conventional multiple organ back-up system blood purification part all adopt peristaltic pump mode, peristaltic pump and occlusion pump, such pump has range of flow large, but flow accuracy fluctuation also larger feature, i.e. pump line inlet and outlet pressure change peristaltic pump can be caused often to rotate fluid flow fluctuation that a circle drives, therefore only cannot meet the requirement to fluid flow precision in blood purification treatment by peristaltic pump self precision.Therefore in blood purification technology application at present, assist while carrying out selecting peristaltic pump driving and with electronic scale weighing system, the liquid weight that peristaltic pump drives is monitored, regulate the rotating speed of peristaltic pump in real time, realize the closed-loop adjustment to peristaltic pump rotating speed by Weight control.
Current multiple organ back-up system on the market arranges an electronic scale device bottom it, this device outside is in hooking shape, inner and electronic scale molality block is connected, liquid bag is suspended from this hook portion, control system calculates the weight of this liquid bag by internal electron scale module, by calculating the weight change of feed liquor bag and fluid bag, control the rotating speed of peristaltic pump.
Because electronic scale all adopts suspended structure, therefore the multiple organ supportive device of these parts is adopted all to be furnished with higher bottom bracket, being lifted by body to certain altitude is that underhung liquid bag reserves requisite space, therefore such machine height is higher, center of gravity is also higher, often topples over the situation damaged machine and injure nurse by a crashing object in moving process, and bulky, difficult, portability is poor.
At present, at medical field, also have and to adopt counter balance pocket system to carry out Flow-rate adjustment, existing counter balance pocket system is made up of the equal chamber of two capacity and eight electromagnetic valves being installed on it.Chamber is divided into left and right two parts by one piece of soft diaphragm by each chamber, and counter balance pocket system, according to the switching combining of electromagnetic valve, has two kinds of mode of operations: normal dialysis pattern and to-fill procedure pattern.This counter balance pocket is in reality dialysis uses, reliable, safeguard simple, and can well ensure the balance of liquid in-out, but if existing counter balance pocket is placed on portable dialysis machine just there are some problems, subject matter has two:
First is that electromagnetic valve is more, and the volume that 8 electromagnetic valves take is comparatively large, and portability is very poor.
Second due to diaphragm be flexible, so in vehicle-mounted mobile process, or waving in the hospital ship of rocking, under the impact of liquid inertia, flexible membrane often produces rub-out signal, cause commutation inaccurate.
