Description
Technical field
This utility model relates to field of medical technology, particularly relates to a kind of de-airing device for purifying blood.
Background technology
Hemodialysis is the Main Means for the treatment of uremia, acute or chronic renal failure.In blood dialysis, easily produce bubble in reverse osmosis water heating link, finally cause in dialysis solution containing bubble, if bubble not eliminated, can air embolism be produced to blood and threaten patient vitals, dialysate flow also can be caused simultaneously unstable, affect dialysis-effect.Usually adopt bubble filtering device to eliminate bubble at present, eradicating efficacy is not good, can not be discharged by gas completely, and add certain medical-risk.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of de-airing device for purifying blood.
This utility model is achieved through the following technical solutions:
A kind of de-airing device for purifying blood, comprise depassing unit, the lower end of described depassing unit is provided with feed tube, described feed tube is connected with the VERTICAL TUBE being positioned at depassing unit, the leakage fluid dram of described VERTICAL TUBE be positioned at be arranged on depassing unit inside base plate on, sealing ring is provided with between described VERTICAL TUBE and base plate, the lower surface of described base plate is provided with at least one vibrating device, negative pressure pump is provided with outside the upper end of described depassing unit, described negative pressure pump is connected with the sucker being arranged on depassing unit inside top, described sucker lower surface is provided with several suction nozzles, the side of described depassing unit is provided with suction catheter, and the liquid feeding end of suction catheter has certain distance between base plate upper surface, the outside of described suction catheter is connected with peristaltic pump.
As preferably, described suction nozzle is horn-like structure, and the diameter of upper end is less than the diameter of lower end.
As preferably, the distance of liquid feeding end between base plate upper surface of described suction catheter is 1mm ~ 2mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, this utility model by carrying out blood micro-ly shaking, vacuum suction double filtration mode, can make air in blood under vibration with suction function with fluid separation applications, easy to use, bubble efficiency is effective, has significant practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. depassing unit; 2. feed tube; 3. VERTICAL TUBE; 4. base plate; 5. sealing ring; 6. vibrating device; 7. negative pressure pump; 8. sucker; 9. suction nozzle; 10. suction catheter; 11. peristaltic pumps.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1, a kind of de-airing device for purifying blood, comprise depassing unit 1, the lower end of described depassing unit 1 is provided with feed tube 2, described feed tube 2 is connected with the VERTICAL TUBE 3 being positioned at depassing unit 1, the leakage fluid dram of described VERTICAL TUBE 3 be positioned at be arranged on depassing unit 1 inside base plate 4 on, sealing ring 5 is provided with between described VERTICAL TUBE 3 and base plate 4, the lower surface of described base plate 4 is provided with at least one vibrating device 6, in practice, in order to keep the balance of base plate 4 in vibration processes, generally guarantee that vibrating device 6 is for even number, and be arranged symmetrically with, microvibration can be carried out to blood, acceleration bubble is separated with blood, negative pressure pump 7 is provided with outside the upper end of described depassing unit 1, described negative pressure pump 7 is connected with the sucker 8 being arranged on depassing unit 1 inside top, described sucker 8 lower surface is provided with several suction nozzles 9, described suction nozzle 9 is in horn-like structure, and the diameter of upper end is less than the diameter of lower end, the bubble in negative pressure pump 7 pairs of blood is made to attract area large like this, effective.
The side of described depassing unit 1 is provided with suction catheter 10, and the liquid feeding end of suction catheter 10 has certain distance between base plate 4 upper surface, in practice, the distance of liquid feeding end between base plate 4 upper surface of getting described suction catheter 10 is 1mm ~ 2mm, guarantee to interfere with the feed tube of suction catheter 10 in the vibration processes of base plate 4, the outside of described suction catheter 10 is connected with peristaltic pump 11.
Its detailed description of the invention is: flowed into from feed tube 2 by blood, through VERTICAL TUBE 3, blood is drained on base plate 4, Vibration on Start-up device 6 and negative pressure pump 7, now there is microvibration in base plate 4, negative pressure pump 7 produces negative pressure in depassing unit 1, make the bubble in blood and blood separation, start peristaltic pump 11 simultaneously and the blood after separation on base plate 4 is discharged by suction catheter 10.Like this by carrying out blood micro-ly shaking, vacuum suction double filtration mode, can make air in blood under vibration with suction function with fluid separation applications, easy to use, bubble efficiency is effective, has significant practicality.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
