Description
Technical field
The utility model relates to medical instruments, especially a kind of hemodialysis simulator.
Background technique
Haemodialysis is to treat the main method of various acute and chronic renal failures, and there is the dimension of registration record in the current whole nation
Holding property hemodialysis patients in 600,000 people or so, the hemodialysis platform time conservative estimation carried out every year also 60,000,000 times with
On.Haemodialysis be under the cooperation of hemo system by by internal blood drainage to external, through one by thousands of hollow fibres
In the dialyzer of composition, blood electrolyte solution (dialyzate) similar with concentration containing body inside and outside hollow fibre one by one,
Mass exchange is carried out by disperse/convection current, intracorporal metabolic waste is removed, maintains electrolyte and acid-base balance；Body is removed simultaneously
Interior excessive moisture, and will be by the whole process of the blood recovery purified.Specific therapeutic process is shown in schematic diagram below:
The process of haemodialysis is a kind of extracorporal circulatory system, need patient's body blood drainage is internal out, in hemo system
It drains intracorporal blood under cooperation to be purified in vitro, this process complication occurs there are bigger Operative risk
A possibility that it is larger, at present by national relevant regulations be required to carry out haemodialysis nursing staff have to pass through certain profession
Training, can clinically be operated after having certain qualification.However, at present due to lacking special trained equipment, shield
The study of reason personnel also according to: this mode is practiced in theory study-clinical probation-clinical tutor guidance-with patient
It carries out, the maximum drawback of this mode is that the nursing staff in study stage can not simulate before treating to patient and really controls
Treatment process, although there is clinical tutor, guidance cannot still avoid the health and lives for jeopardizing patient because of operation error completely on one side.Together
When, the patient that China's chronic kidney hypofunction needs maintenance hemodialysis to treat at present is in explosive growth, the Blood Dialyzing Center people of various regions
Full to suffer from, care-giving professional lacks very much, and traditional band religion mode is difficult to fast and efficiently turn out enough personnel's satisfactions
Clinic needs.
Summary of the invention
The purpose of the utility model is to provide a kind of hemodialysis simulators.
The purpose of this utility model is completed by following technical scheme: a kind of hemodialysis simulator, including the end A is i.e. dynamic
Arteries and veins end interface, the end V, that is, vein end interface, human body soft tissue simulator 3, between the end A and the end V are provided with adjustable electric magnetic clutch
Pipe valve 6, peristaltic pump 8, controller 9, liquid bag 11, it is characterised in that: simulated equipped with vascular puncture 3 one end of human body soft tissue simulator
Section 2,2 one end of vascular puncture analog section are connect by connecting line 1 with peristaltic pump 8, peristaltic pump 8 also pass through connecting line respectively with
Liquid bag 11, air intake duct 10 connect, and air intake duct 10 is equipped with band pipe clamp, and the end V is equipped with bloody path conduit 5, simulate for blood
Liquid passes in and out human body soft tissue simulator 3, and bloody path conduit 5 is equipped with adjustable electromagnetic pinch valve 6, and adjustable electromagnetic pinch valve 6 is another
End is equipped with air pot 12 and air detectors 13, and air pot 12 is exhaust apparatus, and controller 9 passes through control route 7 and peristaltic pump
8, adjustable electromagnetic pinch valve 6 and air detectors 13 connect.
The utility model needs and hemo system, internal fistula puncture needle, haemodialysis filter, hemodialysis pipeline and water process dress
It sets and is used cooperatively.The product can Reusability.The utility model does not need Preservation in sterile condition.The function that the utility model has, 1,
Needs are external out by the blood drainage of intravascular flow from patient's body when haemodialysis, so simulator is firstly the need of simulation people
The blood of intracorporal flowing, general clinical treatment need the blood flow velocity drained in 200-350ml/min or so, patient vessel
Interior blood flow velocity at least will be in 600ml/min or more.2, it can simulate and establish vascular access, blood is drawn from patient's body,
After treatment and in defeated ex vivo.Clinically this access it is usual there are two types of: (1) internal arteriovenous fistula: using two it is dedicated
Internal fistula puncture needle punctures patient vessel, and one drains blood flow internal (commonly referred to as arterial end), and another blood flow defeated time
(commonly referred to as vein end) in vivo.(2) single-needle two-cavity central venous catheter: this conduit is placed in the central vein of patient,
There are two port, one end, and blood flow to be drained at patient's body (commonly referred to as transcatheter arterial end) as outlet for conduit, and the other end is made
Blood flow is drained into patient's body (commonly referred to as conduit vein end) for entrance.3, most maintenance hemodialysis patients make
It with internal arteriovenous fistula, needs to be punctured using internal-fistula needle before treatment, hemodialysis internal-fistula needle is big more than general transfusion needle internal diameter, wears
It is also big many to pierce difficulty, puncture failure will lead to treatment can not carry out, bleeding, infection, the complication such as aneurysm, and nursing
The difficult point of personnel education.Simulator wants the internal arteriovenous fistula that can simulate patient to practice puncturing for nursing staff, and this simulation will use up
It is possible close with true man.
There is one section of pipeline to manufacture in simulator circulation line using artificial blood vessel material-expanded PTFE material, it is interior
Diameter is consistent with the internal arteriovenous fistula of real human body, the human body soft tissue simulator that this section of pipeline heeling-in is manufactured in resin material
It is interior, it can simulate and practice internal fistula puncture for nursing staff using the patient of internal arteriovenous fistula, can preferably be mentioned under the cooperation of B ultrasound
The feel of high practice personnel.The other pipelines of simulator are manufactured using medical PVC material, and this material price is cheap, are easy to add
Work, can Reusability, internal diameter and structure can be adjusted arbitrarily.Simulator pipeline is provided with the end A (arterial end) interface, the end V (vein
End) interface to simulate use central venous catheter patient.Drive blood simulated solution in simulator pipe using medical peristaltic pump
It is flowed in the circulation of road, pump speed range 0-1000ml/min, can be very good blood flow in simulation patient vessel, pass through adjusting
Pump speed can simulate the situation of blood flow deficiency in patient vessel.Use physiological saline+colorant as simulation blood.Using adjustable
Formula electromagnetism pinch valve can simulate clinically artery and vein end drainage not with the flow velocity of separately adjustable arterial end and vein end simulated solution
Smooth situation；Directly close the case where vein end pinch valve can simulate the filter blood coagulation clinically occurred.Arterial end is provided with
Air intake duct can simulate in therapeutic process and gas caused by operation error occurs and enter extracorporal circulatory system.Using different
Toner can simulate the case where filter rupture of membranes.Pipeline is provided with air pot and air detectors, and extracorporal circulatory system is protected after entering air
Accurate, timely processing that reason personnel such as fail, air, which enters air pot and detected by air detectors, alarms, and prompts practice
Personnel are mishandling.
The utility model hemodialysis simulator needs the patient for carrying out haemodialysis and was treating to simulate
The special circumstances being likely to occur in journey, can preferably cultivate care-giving professional, at the same can also for hemodialysis equipment manufacturer into
Row product test and detection.
