Description
Technical field
The invention belongs to medical instruments field, more particularly to a kind of gravity type haemodialysis equipment.
Background technology
Haemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy, and it is by the way that internal blood is drawn
Flow to it is external, through one by the dialyzer that is formed without several hollow fibres, the blood electrolyte similar to concentration containing body is molten
Liquid（Dialyzate）One by one inside and outside hollow fibre, mass exchange is carried out by disperse/convection current, remove internal metabolic waste,
Maintain electrolyte and acid-base balance；Moisture excessive in vivo is removed simultaneously, and by by the whole process of the blood recovery purified
Referred to as haemodialysis.Haemodialysis will use haemodialysis control unit, traditional haemodialysis control unit be divided into blood monitoring warning system and
Dialysis liquid supply system two parts, blood monitoring warning system include blood pump, heparin pump, the monitoring of sound pulse pressure and air monitering
Deng；Dialyse liquid supply system include temperature control system, liquid mixing system, off gas system, monitored conductivity system, ultrafiltration monitoring and
The parts such as blood monitoring are leaked to form.Its operation principle is：Dialysis concentrate and water for dialysis are prepared by dialysis liquid supply system
Into qualified dialyzate, by haemodialyser, the patient blood drawn with blood monitoring warning system carries out solute dispersion, oozed
Saturating and ultrafiltration；Patient blood after effect is guarded warning system by blood and returned in patient body, while after use of dialysing
Liquid is discharged as waste liquid by dialysis liquid supply system, is constantly moved in circles, and completes whole dialysis procedure.Due to traditional blood
Dialysis apparatus is dialysed by the way of force (forcing) pump, and shortcoming is that volume is big, it is high to spend, flow complexity.Product of the present invention is using different
Impurity in the nucleopore UF membrane blood or body fluid in aperture, is dialysed according to the filtration needs that patient is different, and nucleopore membranes are situated between
Matter density can be selected 0.2 micron, 3 microns, 5 microns, and this product does not need dialysis machine, can be carried out in community clinic, and price is low,
Process operation is simple, and market prospects are had an optimistic view of.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of gravity type haemodialysis equipment, and the device is by a cylinder group
Into the upper end of, cylinder be provided with blood inlet, be provided with filter membrane in cylinder, the lower end of cylinder is provided with blood outflow port.
The technical solution adopted by the present invention is：
A kind of gravity type haemodialysis equipment, the device are made up of a cylinder, including：Blood inlet 1, filter membrane 2, blood
Flow export 3；Blood inlet 1 is arranged at the upper end of cylinder, and filter membrane 2 is arranged in cylinder, and blood outflow port 3 is arranged at cylinder
Lower end.
The present invention further technical scheme be：
Described cylinder is made up of medical polyvinyl material.
Described filter membrane is vertically installed in the centre of cylinder, and the space of inner barrel is divided into two.
Described filter membrane is that three layers of nucleopore membranes form.
The Media density of three layers of described nucleopore membranes is 5 microns, 3 microns, 0.2 micron, the distributing order of three layers of nucleopore membranes
It is from left to right 5 microns, 3 microns, 0.2 micron.
The beneficial effects of the invention are as follows：A kind of gravity type haemodialysis equipment is provided, the gravity type haemodialysis equipment
The advantages that simple in construction, cheap, simple to operate, haemodialysis can be carried out in community clinic, and using effect is good.
Brief description of the drawings
Structure chart for the present invention as shown in Figure 1.
Embodiment
With reference to specific embodiment, the present invention is described in further detail.
1. after first carrying out strict sterilization before this product before using, it would be desirable to which the blood of dialysis fills from gravity type haemodialysis
The blood inlet 1 put is pumped into the cylinder of gravity type haemodialysis equipment, stands a few hours, work of the blood in gravity in cylinder
Under, the right side of filter membrane is gradually penetrated on the left of filter membrane, the impurity part in blood is obstructed in filter membrane by filter membrane
Left side or nucleopore membranes interlayer in, what right side obtained is exactly the blood after dialysis, after processing feed back human body in.
Certainly, the present invention also has other embodiments, any skill done under the spiritual background without departing from the present invention
The improvement of art, principle and technique, is within the scope of the present invention.
