Background technology
Hemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy.Along with blood purification technology development and maturation, obtain extensive and general application, it is by being drained to external by body inner blood, through one by the dialyser forming without several hollow fibres in, blood to containing the similar dialysis solution of body concentration inside and outside hollow fibre one by one, carry out mass exchange by disperse convection current, remove metabolic waste in body, maintain electrolyte and acid-base balance; Remove too much moisture in body simultaneously
Traditional dialyser adopts hollow fibre composition, and its dialytic efficiency is low on the one hand, and is difficult for sealing between hollow fibre, easily occurs that dialysis solution sneaks into the generation of blood situation; On the other hand, dialyser lacks temperature control mechanism, easily causes patient temperature fluctuation excessive, particularly in cold winter, needs other auxiliary blood that dialysis is refluxed that arrange to heat, and it is very inconvenient to use.
Utility model content
It is high and have a haemodialysis equipment of heating and heat preserving function that the purpose of this utility model is to provide a kind of dialytic efficiency.
For realizing the technical scheme that the purpose of this utility model adopts be: a kind of haemodialysis equipment, comprise dialysate chamber, blood input pipe, blood outlet tube, dialysis solution input pipe and dialysis solution outlet tube, described dialysate chamber comprises dialysate chamber and is arranged on the blood temporary storing bin in described dialysate chamber, blood converges storehouse and some semipermeable membrane interlayers, described blood temporary storing bin and described blood converge storehouse and are communicated with by described semipermeable membrane interlayer, described blood input pipe is communicated with described blood temporary storing bin, described blood outlet tube converges storehouse with described blood and is communicated with, described dialysis solution input pipe and described dialysis solution outlet tube are all communicated with described dialysate chamber, described dialysate chamber arranges temperature control mechanism outward.
Described dialysis solution input pipe and described blood outlet tube are arranged on the lower end of described dialysate chamber.
Described dialysis solution outlet tube and described blood input pipe are arranged on the upper end of described dialysate chamber.
Described temperature control mechanism comprises the electrothermal layer and the temperature sensor that are arranged on outside described dialysate chamber, and described electrothermal layer is all connected with power line by temperature controller with temperature sensor.
On described dialysis solution input pipe, be arranged on booster pump.
On described dialysis solution outlet tube and described blood outlet tube, be provided with and detect liquid outlet.
Described semipermeable membrane interlayer is cellulose dialyser product.
Haemodialysis equipment of the present utility model converges storehouse by the blood temporary storing bin and the blood that are communicated with by semipermeable membrane interlayer are set in dialysate chamber, on the one hand arterial blood is fully distributed in each semipermeable membrane interlayer in blood temporary storing bin, in converging storehouse, blood converges on the other hand, thereby effective guarantee returns to the blood flow in patient body, and adopt semipermeable membrane sandwich, can fully improve the contact area of blood and dialysis solution, effectively improve the dialytic efficiency of blood; By at dialysate chamber, temperature control mechanism being set outward, thereby the blood heat after effective guarantee dialysis avoids blood heat too low, patient is caused to discomfort, and adopt temperature sensor and temperature controller to control the heat that electrothermal layer produces, be convenient to realize temperature automatically controlled, handling safety, easy.Dialysis solution input pipe and blood outlet tube are arranged on the lower end of dialysate chamber, dialysis solution outlet tube and blood input pipe are arranged on the upper end of dialysate chamber, make blood and dialysis solution adopt reverse flow, can effectively make blood fully be dialysed, and blood relies on self gravitation to flow, and avoids adopting mechanism's supercharging to cause the unnecessary damages such as blood macromole cell rupture; On dialysis solution input pipe, be arranged on booster pump, effectively realize the low in and high out of dialysis solution; Detect liquid outlet by arranging on dialysis solution outlet tube and blood outlet tube, can effectively detect dialyse dialysis solution composition later and the composition of blood, ensure the safety of dialysis.
