Description

Multifunctional monitoring device for hemodialysis machine pipeline

Technical Field

The utility model relates to the field of medical equipment, especially, relate to multi-functional monitoring device of hemodialysis machine pipeline.

Background

Hemodialysis machines (also known as hemodialysis machines) are the main extracorporeal circulation devices used to treat acute and chronic renal failure. The hemodialysis machine mainly comprises a blood pipeline, a blood pump, a dialyzer, a dialysate supply device, an arterial pot, a venous pot and a pressure monitoring device, wherein the blood pump, the arterial pot, the dialyzer and the venous pot are sequentially connected through the blood pipeline, the blood pump is connected with a human artery, and the venous pot is connected with a human vein. The operating principle of the hemodialysis machine is as follows: the blood pipeline leads the blood in the human body out of the body under the action of the blood pump and conveys the blood to the arterial pot, and then leads the blood into the dialyzer from the arterial pot, and the blood and the qualified dialysate prepared by concentrated solution and water through the dialysate supply device in the dialyzer carry out solute diffusion, osmosis and ultrafiltration; the blood of the patient after the action is introduced into the venous pot and then is conveyed back to the body of the patient through a blood pipeline by the venous pot, and the liquid after dialysis is taken as waste liquid and is discharged by the dialysate supply device; the whole dialysis process is completed by continuous circulation.

In the hemodialysis process, the pressure in an external circulation pipeline formed by connecting a blood pump, an arterial pot, a dialyzer and a venous pot can be high and low, different problems occurring in the external circulation pipeline can be explained by different changes of the pressure, and if the pressure changes cannot be found and treated in time, a plurality of problems are brought to clinical care, great influence is brought to treatment, and even the life of a patient is endangered. Therefore, the monitoring and control of pressure during hemodialysis is one of the difficulties in clinical care work, and the pressure monitoring device mainly comprises an arterial pressure monitoring mechanism and a venous pressure monitoring mechanism, wherein the arterial pressure monitoring mechanism can be divided into a pre-pump arterial pressure monitoring mechanism and a post-pump arterial pressure monitoring mechanism according to the difference of the types of the hemodialysis machine and the used blood pipeline. The pre-pump arterial pressure monitoring mechanism mainly reflects the arterial blood vessel access problem, and the post-pump arterial pressure monitoring can better explain the blood coagulation problem of the dialyzer. Most dialysis center (room) only monitors venous pressure at present, think can know with it whether the blood flow of blood pipeline is sufficient, actually not so, if the blood pump rotational speed that the machine set up is too high, and the flow of patient's blood pipeline is not enough just can not arouse venous pressure to report to the police, only leans on preceding arterial pressure monitoring mechanism of pump to explain artery vascular access problem betterly, and preceding arterial pressure monitoring of pump has reflected and has inhaled the blood of patient's blood pipeline artery end and reach the required pressure of blood pump section pipeline. Because the blood treated by the dialyzer is easy to coagulate and can cause the blockage of the venous pot, the existing hemodialysis machine generally monitors the pressure of the venous pot and the pressure of the artery before the pump, but because the blood condition of a patient is high, the blood concentration of some patients is easy to coagulate, and after the blood is introduced into the arterial pot through a blood pump, the blood can coagulate in the arterial pot, which can cause the blockage of the arterial pot, the pressure of the arterial pot needs to be monitored, but the problem of coagulation in the arterial pot does not occur frequently, the arterial pot does not need to be monitored in real time, the pressure in the arterial pot only needs to be monitored at intervals, if a pressure monitoring mechanism is specially equipped for the arterial pot, the resource waste can be caused, the cost is increased, the venous pressure of the venous pot and the pressure of the artery before the pump need to be monitored in real time, the existing hemodialysis machine does not have good capability of monitoring the hemodialysis machine pipeline.

And when the external circulation pipeline of the existing dialysis machine monitors the blood coagulation, the whole external circulation pipeline can only be replaced, so that a large amount of blood is lost for a patient, time is required for replacing medical appliances, and better emergency treatment can not be realized on the problems.
