Abstract
The utility model is a hemodialysis device, which comprises a hemodialyzer (1). The utility model is characterized in that the blood inlet and outlet end of one end of the hemodialyzer (1) is connected with an artery blood circulation conduit (2), a three way tube (3) is connected on the artery blood circulation conduit (2), a decoagulant addition conduit (4) is connected with the three way tube (3), the tail end of the decoagulant addition conduit (4) is connected with a decoagulant injector (5), the blood inlet and outlet end of the other end of the hemodialyzer (1) is connected with a vena blood circulation conduit (6), a drug adding short-tube is arranged on the vena blood circulation conduit (6), the dialyzate holes of the both side ends of the hemodialyzer (1) are connected with two dialyzate circulation conduits (8,9), and the other ends of the two dialyzate circulation conduits (8,9) are connected with two dialyzate bags (10,11).
Description
Technical field
This utility model relates to a kind of armarium, relates in particular to the device that a kind of hemodialysis is used.
Background technology
Hemodialysis is the important means that the anxious poison of treatment, chronic uremia and some drugs are poisoned, but the general complex structure of in hospital, using at present of haemodialysis equipment, bulky and depend on water source and power supply, when cutting off the water or having a power failure suddenly, bring great influence can for ongoing hemodialysis, increase patient's misery.
The utility model content
Technical problem to be solved in the utility model provides a kind of water source, power supply and haemodialysis equipment simple in structure of not relying on.
For solving the problems of the technologies described above, the technical solution of the utility model is: haemodialysis equipment, comprise hemodialyzer, blood manhole appendix at described hemodialyzer one end is connected with the arterial blood circulation conduit, be connected with tee T on the described arterial blood circulation conduit, described tee T is connected with and appends the anticoagulant conduit, the described end that appends the anticoagulant conduit is connected with the anticoagulant syringe, blood manhole appendix at the described hemodialyzer other end is connected with the venous blood circulation conduit, described venous blood circulation conduit is provided with the dosing short tube, be connected with dialysis liquid circulating tube on the dialysate hole of the two side ends of described hemodialyzer, the other end of described dialysis liquid circulating tube is connected with dialyzate bag.
As a kind of improvement, described arterial blood circulation conduit is provided with the arterial blood drawing specimen hole, and described venous blood circulation conduit is provided with the venous blood collection specimen hole.
Owing to adopted technique scheme, haemodialysis equipment, comprise hemodialyzer, blood manhole appendix at described hemodialyzer one end is connected with the arterial blood circulation conduit, be connected with tee T on the described arterial blood circulation conduit, described tee T is connected with and appends the anticoagulant conduit, the described end that appends the anticoagulant conduit is connected with the anticoagulant syringe, blood manhole appendix at the described hemodialyzer other end is connected with the venous blood circulation conduit, described venous blood circulation conduit is provided with the dosing short tube, be connected with dialysis liquid circulating tube on the dialysate hole of the two side ends of described hemodialyzer, the other end of described dialysis liquid circulating tube is connected with dialyzate bag; Simplified the structure of haemodialysis equipment greatly, this device does not rely on water source, power supply, be not subjected to the influence of cutting off the water suddenly or having a power failure in the therapeutic process, and this device is easy to use, and low being convenient to of cost is popularized and is promoted.
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment;
The specific embodiment
Haemodialysis equipment as shown in drawings, comprise hemodialyzer 1, blood manhole appendix at described hemodialyzer 1 one ends is connected with arterial blood circulation conduit 2, be connected with tee T 3 on the described arterial blood circulation conduit 2, described tee T 3 is connected with and appends anticoagulant conduit 4, the described end that appends anticoagulant conduit 4 is connected with anticoagulant syringe 5, blood manhole appendix at described hemodialyzer 1 other end is connected with venous blood circulation conduit 6, described venous blood circulation conduit 6 is provided with dosing short tube 7, be connected with dialysis liquid circulating tube 8 on the dialysate hole of the two side ends of described hemodialyzer 1,9, the other end of described dialysis liquid circulating tube 8 is connected with dialyzate bag 10,11.
Described arterial blood circulation conduit 2 is provided with arterial blood drawing specimen hole 21, and described venous blood circulation conduit 6 is provided with venous blood collection specimen hole 61.
The operation principle of present embodiment is as follows:
When through sterilization, flushing, emptying the substitute the bad for the good hemodialyzer 1 of anticoagulant of gas and desiring, arterial blood circulation conduit 2 and venous blood circulation conduit 6 are with after human body artery, vein are connected respectively, blood promptly leans on the driving force of heart, from tremulous pulse → arterial blood circulation conduit 2 → hemodialyzer 1 → venous blood circulation conduit 6 → vein, be back in the body, circulation repeatedly is without blood pump.
When the dialyzate bag 10 of dialysis solution is filled in rising, promptly by gravity, atmospheric pressure is through dialysis liquid circulating tube 8 for dialysis solution, flow into hemodialyzer 1, flow out at another dialysate hole, flow in the sky dialyzate bag 11, treat that elevated dialyzate bag stream is empty through dialysis liquid circulating tube 9 from hemodialyzer 1, upset at once, replace repeatedly, regularly change fresh dialysis solution, the liquid pump of need not dialysing.
According to the state of an illness, the general per 30 minutes once fresh dialysis solution of replacing, each 2000ml.After the diafiltration treatment beginning, regularly append anticoagulant conduit 4 injection anticoagulant, as using the hemodialyzer that does not need anticoagulant, then without anticoagulant.
Claims (2)
1. haemodialysis equipment, comprise hemodialyzer (1), it is characterized in that: the blood manhole appendix at described hemodialyzer (1) one end is connected with arterial blood circulation conduit (2), be connected with tee T (3) on the described arterial blood circulation conduit (2), described tee T (3) is connected with and appends anticoagulant conduit (4), the described end that appends anticoagulant conduit (4) is connected with anticoagulant syringe (5), blood manhole appendix at described hemodialyzer (1) other end is connected with venous blood circulation conduit (6), described venous blood circulation conduit (6) is provided with dosing short tube (7), be connected with dialysis liquid circulating tube (8 on the dialysate hole of the two side ends of described hemodialyzer (1), 9), described dialysis liquid circulating tube (8,9) the other end is connected with dialyzate bag (10,11).
