Abstract
The utility model relates to a blood drainage purifying device, comprising an intelligentized asynchronous module realized by a PLC (programmable logic controller) and a controlled solenoid valve provided with a flow sensor and additionally arranged on commonly used blood purifying equipment and a blood drainage apparatus. An asynchronous dual-needle induction blood drainage and asynchronous blood returning mechanism is adopted, the blood flow requirement of the blood purifying equipment is achieved by providing single-time less blood flow, subjected to combining, to the traditional blood purifying equipment through utilizing an electronic intelligent control system to control the blood flow direction and the blood returning moment in the vitro and vivo blood exchange process, so hemodialysis induced by low flow is realized. The blood drainage purifying device is capable of reducing the pain caused by puncture during blood drainage, reducing the coagulation possibility, and improving the safety of blood purifying, and can facilitate and simplify the operation and reduce the training cost if being clinically applied.

Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining this utility model, is not for limiting scope of the present utility model.
As shown in Figure 1, a kind of blood drainage purifier, comprise the intelligent asynchronous control module that is realized by PLC, and the controlled solenoid valve of the band flow transducer that installs additional at blood cleaning equipment commonly used and blood drainage device and device thereof, specifically comprise the injection puncture needle, two-way miniature peristaltic pump 1, the first blood buffer kettle 2, the second blood buffer kettle 3, normal saline bottle 4, blood purification kettle 5, blood pump 6, blood purification 7, silica gel infusion tube 8, glass tubing 10, rubber purge hose 9 and intelligent asynchronous control module, described injection puncture needle by silica gel infusion tube 8 respectively with the lower end of the first blood buffer kettle 2, the lower end of the second blood buffer kettle 3 links to each other, link to each other by glass tubing 10 between 3 upper ends of the lower end of the described first blood buffer kettle 2 and the second blood buffer kettle, the lower end of the described first blood buffer kettle 2, the lower end of the second blood buffer kettle 3 links to each other with normal saline bottle 4 respectively by glass tubing 10, the lower end of the described first blood buffer kettle 2, the lower end of the second blood buffer kettle 3 links to each other with the lower end of blood purification kettle 5 by silica gel infusion tube 8, described normal saline bottle 4 links to each other with the upper end end of blood purification kettle 5 by glass tubing 10, described blood purification kettle 5 upper and lower sides are provided with opening in addition, and link to each other with blood purification 7 respectively by rubber purge hose 9;
Be provided with two-way miniature peristaltic pump 1 at described silica gel infusion tube 8, the rubber purge hose 9 that described blood purification kettle 5 lower ends are linked to each other with blood purification 7 is provided with blood pump 6;
Be equipped with controlled solenoid valve 11 on described glass tubing 10, silica gel infusion tube 8 and the rubber purge hose 9;
The asynchronous control module of described intellectuality is carried out on-off control to controlled solenoid valve 11 and two-way miniature peristaltic pump 1.
This utility model adopts asynchronous crosspointer to induce to draw blood and asynchronous blood back mechanism, carry out single channel by the injection puncture needle at medium-sized vein and venule and draw blood, this process is not carried out earlier blood back, enter the first blood buffer kettle 2 when drawing blood, behind the second blood buffer kettle 3, monitoring to the blood of each phase-splitting, obtain each phase-splitting of blood and purify index, pass through the controlled solenoid valve 11 of accommodation zone flow transducer on this basis, with blood process interflow, restart the loop after differentiation and the multistage purification and make blood backflow body, this moment, remaining blood continued to carry out further purification process in the high speed blood circulation, then under intelligence system control, when arriving to the next backflow window time, proceed asynchronous blood back process, move in circles, the blood purification rate of major cycle will be higher than the single purification like this, simultaneously because first of blood drainage ceaselessly adds the blood that does not purify in circulation, major cycle purifies like this, and asynchronous backflow continues to carry out, and finally reaches the normal requirement of blood purification.Simultaneously, adopt buffering and intelligent control technology, accelerate blood drainage and blood back time, reducing blood coagulation may, and utilize external high speed closed cycle to improve blood purification efficient and safety, and the used injection puncture needle of this device also can alleviate patient's misery, the professional operator's of minimizing training simultaneously expense and time.
The asynchronous crosspointer that this utility model adopts is induced and is drawn blood and asynchronous blood back mechanism, and the specific embodiment is:
At first when drawing blood, utilize time difference, directly do not carry out blood back, and be to use two-way injection puncture needle respectively in the first blood buffer kettle 2, the second blood buffer kettle 3 body of drain simultaneously inner blood to system, to accelerate the drain total amount; The first blood buffer kettle 2, the second blood buffer kettle 3 are sent blood wherein in the blood purification kettle 5 to then;
This moment, blood entered in the independent secondary repetitive cycling, and namely the blood circulation of blood purification kettle 5, rubber purge hose 9, blood pump 6 and blood purification 7 formation circulates repeatedly at this;
(this moment, the blood purification index was up to standard substantially after repeatedly when blood purification then, the body project has difference according to the blood cleaning equipment difference), blood is back to the second blood buffer kettle 3 and is back to human body under the control of corresponding two-way miniature peristaltic pump 1, meanwhile, 1 right execution of the first blood buffer kettle 2 and its related bidirectional miniature peristaltic pump is drawn blood to the process of blood purification kettle 5;
At last, when blood purification total time to the time, open the first blood buffer kettle 2, the second blood buffer kettle 3 and related bidirectional miniature peristaltic pump 1 simultaneously and start the blood back process, fast whole blood in blood purification kettle 5 and the whole extracorporeal blood circulation system is back to human body.
Above process is because to draw the blood blood back be not carry out simultaneously under relatively independent situation, induces and draws blood and asynchronous blood back mechanism so abbreviate the step crosspointer as.
The above only is preferred embodiment of the present utility model, and is in order to limit this utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
