Technical scheme of the present invention is as follows: a kind of apparatus for purifying blood of process capable of circulation, comprise osmotic engine (3) and drive (9), its key is: a film nipple of described osmotic engine (3) is connected with time catheter (2), another film nipple of osmotic engine (3) is connected with main catheter (1), and this main catheter (1) walks around main circulation pump (4); The side of the film coupling of described osmotic engine (3) is connected with main logical liquidus, opposite side is connected with time logical liquidus, and described master is led to after liquidus walks around secondary circulating pump (5), is connected with filling bag (6), described time logical liquidus is walked around after circulating pump (7), is connected with waste discharge bag (8); Described main circulation pump (4), secondary circulating pump (5) and be electrically connected with driving (9) respectively by wire from circulating pump (7).
The present invention is mainly used in acute or chronic renal failure patient, and the main purpose of running is: 1, remove the toxin in blood of human body, make human internal environment reach acid-base balance simultaneously; 2, ultrafiltration from human body is realized.
Primary and secondary catheter in the present invention is connected with the blood vessel of human body respectively, forms blood circuit.Under the driving of main circulation pump, blood enters in the film of main catheter and osmotic engine from human vas successively, then enters time catheter, and finally feeds back in human vas, forms continuous print extracorporeal circulation of blood.Meanwhile, under the driving of secondary circulating pump, the liquid in filling bag enters the film of osmotic engine from main logical liquidus, and the liquid outside this osmotic engine film is entering time logical liquidus under the driving of circulating pump, and finally enters in waste discharge bag.The present invention does not need external water treatment facilities, not only greatly reduces production cost, and simple to operate, and the quick rescue of emergency department and bed side can be facilitated to move.
Described catheter is provided with air monitor (10) and clamp (11), and this air monitor (10) and clamp (11) are electrically connected with driving (9) respectively by wire.When air monitor monitors in time catheter and has bubble, can report to the police and bubble information is transferred to driving, sending instruction by driving, making blocking-up clamp time catheter, to prevent air from entering human body, not only safe but also reliable.
Occur that hemocyte enters in logical liquidus for preventing osmotic engine rupture of membranes, described logical liquidus is provided with sensor (12), this sensor (12) is electrically connected with driving (9) by wire, hemocyte in Sensor monitoring time logical liquidus, treatment is then stopped, in order to avoid cause patient to lose blood if any warning.
Described filling bag (6) and waste discharge bag (8) are symmetricly set on same balance (13), and this balance (13) is electrically connected with driving (9) by wire; Or described filling bag (6) and waste discharge bag (8) are arranged on two balances (13) respectively, these two balances (13) are electrically connected with driving (9) by wire.Drive the weight change according to the filling bag on balance and waste discharge bag, feedback control time circulating pump and the rotating speed from circulating pump, the secondary circulating pump control unit interval enters the fluid flow outside osmotic engine film, control unit interval amount of liquid out from osmotic engine film from circulating pump, and be the ultrafiltration amount from human body from the amount of liquid of circulating pump unnecessary circulating pump.
The invention has the beneficial effects as follows:
1) complete machine structure is simple, easy and simple to handle, the convenient quick rescue being used for emergency department.
2) do not need external water treatment facilities, greatly reduce production cost, and facilitate the bed of emergency department other mobile.
3) displacement liquid or dialysis solution freely can be prepared according to the different situations normal saline of patient and other injection, and the disease of adaptation is wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, the present invention by main catheter 1, secondary catheter 2, osmotic engine 3, main circulation pump 4, secondary circulating pump 5, filling bag 6, from circulating pump 7, waste discharge bag 8, drive 9, air monitor 10, clamp 11, the parts such as sensor 12 and balance 13 form.Wherein, the main side of catheter 1 is connected with the side of human vas, after the opposite side of this main catheter 1 walks around main circulation pump 4, be connected with a film nipple of osmotic engine 3, another film nipple of this osmotic engine 3 is connected with a side connector on time blood vessel road 2, the opposite side joint on secondary blood vessel road 2 is connected with the opposite side of human vas, forms blood circuit.
As can be known from Fig. 1, the side of the film coupling of osmotic engine 3 and main logical liquidus are connected, and opposite side is connected with time logical liquidus, and described master is led to after liquidus walks around secondary circulating pump 5, and be connected with filling bag 6, described secondary logical liquidus is walked around after circulating pump 7, is connected with waste discharge bag 8.Described filling bag 6 and waste discharge bag 8 can be symmetricly set on same balance 13, also can be arranged on two balances 13 respectively, and described balance 13 is electrically connected with driving 9 by wire.Described main circulation pump 4, secondary circulating pump 5 and 9 to be electrically connected with driving respectively by wire from circulating pump 7.Described catheter is provided with air monitor 10 and clamp 11, and this air monitor 10 and clamp 11 are electrically connected with driving 9 respectively by wire.Described logical liquidus is provided with sensor 12, and this sensor 12 is electrically connected with driving 9 by wire.
Operation principle of the present invention is as follows:
Under the driving of main circulation pump 4, blood enters in the film of main catheter 1 and osmotic engine 3 successively from human vas, then enters time catheter 2, and finally feeds back in human vas, forms continuous print extracorporeal circulation of blood.Meanwhile, under the driving of secondary wriggling 5, the liquid in filling bag 6 enters the film of osmotic engine 3 from main logical liquidus, and the liquid outside this osmotic engine 3 film enters time logical liquidus under the driving from circulating pump 7, and finally enters in waste discharge bag 8.
Drive the weight change according to the filling bag 6 on balance 13 and waste discharge bag 8, feedback control time circulating pump 5 and the rotating speed from circulating pump 7, when being greater than the flow of time circulating pump 5 from the flow of circulating pump 7 in the unit interval, the difference of two circulating pumps is from the ultrafiltration inside blood of human body.In the process, toxin in blood of human body constantly moves in osmotic engine 3 film to film, reach the object removing toxin in blood of human body, because the normal concentration of the liquid electrolyte in filling bag 6 and blood of human body is close, therefore while can the acid-base balance of warrantor's internal milieu.Air monitor 10 in monitoring of blood with or without air, if any then reporting to the police, and making clamp 11 clamp time catheter by driving 9, preventing air from entering human body.Sensor 12 has achroacyte for monitoring in logical liquidus, if any then reporting to the police, and stops treatment, in order to avoid cause patient to lose blood by driving 9.
Two balances are connected with waste discharge bag and filling bag respectively.
