Description
Technical field
The utility model belongs to technical field of medical instruments, is specifically related to a kind of uremic patient hemodialyzer.
Background technology
Uremia is not an independent disease, but the clinical syndrome that the nephropathy in various late period is total, is the syndrome that a series of clinical manifestations that chronic renal failure occurs when entering end stage eventually form. Hemodialysis, is called for short hemodialysis, and popular saying is also referred to as kidney machine, washes kidney, is the one of blood purification technology. It utilizes semi-permeable membranes principle, by diffusion, moves out external to various harmful and unnecessary metabolic wastes and too much ionogen in fluid, reaches the object of purification blood, and reach the object correcting Water-Electrolyte and acid base equilibrium.
The semi-permeable membranes thickness that hemodialysis uses is 10-20 micron, and the aperture averaging on film is 3 nanometers, thus only allow molecular weight be less than 1.5 ten thousand small molecules and part medium molecular substance pass through, and the macromolecular substance that molecular weight is greater than 3.5 ten thousand not by. Therefore, protein, pyrogeneous substance, virus, bacterium and hemocyte etc. all can not appear; In the composition of urine, major part is water, wants to substitute kidney with kidney machine and just must discharge a large amount of moisture from blood, and kidney machine can only utilize osmotic pressure and ultrafiltration pressure to reach the object removing too much moisture. The kidney machine and the haemodialysis equipment that use now all possess these functions above-mentioned, thus are regulated by the quality and quantity of blood, make it to be bordering on physiological status.
Hemodialyzer needs the sufferer carrying out hemodialysis to have significance on clinical. As application number be 201420280946.3 practical novel just propose a kind of haemodialysis equipment, there are the following problems for hemodialyzer in the apparatus: one, to contact dialysis area with dialyzate limited for blood; Two, dialyzer inner blood pressure is less, and dialytic efficiency is lower.
Practical novel content
Technical problem to be solved in the utility model overcomes above-mentioned defect, it is provided that a kind of effectively increase blood and dialyzate contact area, it is to increase the hemodialyzer of internal blood pressure.
In order to realize above-mentioned purpose, the utility model is achieved by the following technical solutions:
A kind of uremic patient hemodialyzer, comprise housing 1, it is characterized in that: housing 1 top is connected with pressure ring lid 2, pressure ring lid 2 side is provided with blood entry port 21, spiral semipermeable membrane device 3 is installed in housing 1, spiral semipermeable membrane device 3 comprises the spiral semi-permeable membranes passage 32 of rotating shaft 31 and upper coiling thereof, rotating shaft 31 is hollow structure, its top is provided with dialyzate entrance 311, bottom is provided with hole 312, housing 1 upper side is provided with dialyzate outlet 11, and housing 1 bottom is connected with bottom 4, and bottom 4 side is provided with blood outlet 41.
Encapsulation process is all made in described housing 1 and the junction of pressure ring lid 2 and bottom 4.
Described spiral semi-permeable membranes passage 32 adopts high strength semipermeable membrane material.
Its useful effect is: the utility model adopts spiral semipermeable membrane device, namely add the contact area of blood and dialyzate, turn improve liquid pressure in dialyzer, and it is adjustable to achieve internal pressure, be conducive to improving hemodialysis efficiency, for Urology Department's medical work is provided convenience.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model shells body sectional view.
Shown in figure: housing 1, dialyzate outlet 11, pressure ring lid 2, blood entry port 21, spiral semipermeable membrane device 3, rotating shaft 31, dialyzate entrance 311, hole 312, spiral semi-permeable membranes passage 32, store battery 8, bottom 4, blood outlet 41.
Embodiment
Below in conjunction with accompanying drawing 1,2, structure of the present utility model and useful effect thereof are illustrated further.
Example 1
A kind of uremic patient hemodialyzer, comprise housing 1, it is characterized in that: housing 1 top is connected with pressure ring lid 2, pressure ring lid 2 side is provided with blood entry port 21, spiral semipermeable membrane device 3 is installed in housing 1, spiral semipermeable membrane device 3 comprises the spiral semi-permeable membranes passage 32 of rotating shaft 31 and upper coiling thereof, rotating shaft 31 is hollow structure, its top is provided with dialyzate entrance 311, bottom is provided with hole 312, housing 1 upper side is provided with dialyzate outlet 11, and housing 1 bottom is connected with bottom 4, and bottom 4 side is provided with blood outlet 41.
Also separate by high strength semipermeable membrane material between described semi-permeable membranes passage 32 and rotating shaft 31, blood can flow along with spiral semi-permeable membranes passage 32 after entering from the blood entry port 21 of pressure ring lid 2 side, simultaneously, after dialyzate enters from the dialyzate entrance 311 at rotating shaft 31 top, flow out from the hole 312 of bottom, just relative with direction of flow of blood, dialyzate is upwards discharged through the dialyzate outlet 11 of housing 1 upper side along with the rotation of spiral semipermeable membrane device 3, and the blood through dialysis flows out from the blood outlet of bottom 4 side again.
The power set that the rotating speed of described spiral semipermeable membrane device 3 is connected by outside can regulate, thus when other condition is constant, it is achieved the adjustment of internal pressure in dialysis procedure.
Above embodiment is only the utility model a kind of enforcement mode wherein, and it describes comparatively concrete, but therefore can not be interpreted as the restriction to the utility model patent scope. It is noted that for the person of ordinary skill of the art, not departing under prerequisite of the present utility model, it is also possible to make some distortion and improvement, these all belong to the protection domain of this practicality. Therefore, the protection domain of the utility model patent should be as the criterion with claims.
