Problems solved by technology

[0004] The present invention provides a hemodialysis device for nephrology, which has the beneficial effect of real-time deployment of dialysate on-site for the patient's blood concentration, required electrolyte and base concentration and other conditions to achieve the best curative effect, and solves the problems mentioned in the background technology above. When the existing hemodialysis equipment is dialyzed, the dialysate is prepared in advance by diluting the concentrated dialysate containing electrolytes and bases and the reverse osmosis water in proportion, and it cannot be based on the real-time concentration of the patient's blood and the required electrolytes and The on-site preparation of the base concentration leads to the problem that the curative effect of dialysis cannot be optimal

Embodiment 1

[0030] see Figure 1-7 , a kind of hemodialysis equipment for nephrology, comprising a dialysis machine 1, a blood detector 2 and a tank body 3 are arranged on the dialysis machine 1, and a plurality of feeding pipes 301 are arranged on the tank body 3, and inside the plurality of feeding pipes 301 are A solenoid valve 302 is provided, and a frame 4 is also provided on the tank body 3;

[0031] The tank body 3 is provided with a first mixing mechanism 5, the first mixing mechanism 5 includes a first rotating rod 501 rotatably arranged on the tank body 3, and a plurality of first stirring blades 502 are arranged on the first rotating rod 501;

[0032] The tank body 3 is also provided with an infusion mechanism 7, the infusion mechanism 7 includes an infusion tube 701 rotatably arranged on the frame 4, the infusion tube 701 is rotatably arranged in the first rotating rod 501, and the infusion tube 701 is connected with the dialysis machine 1, the second A rotating rod 501 is pr...

Embodiment 2

[0039] see Figure 1-7 , the tank body 3 is provided with a second mixing mechanism 6, the second mixing mechanism 6 includes two second rotating rods 601 which are rotatably arranged on the tank body 3, and the two second rotating rods 601 are symmetrically arranged in the tank body 3 , the two second rotating rods 601 are provided with a plurality of second stirring blades 602 .

[0040] In this embodiment: in order to make the mixing of the components more uniform and the formation of the dialysate more rapid, a second mixing mechanism 6 is also provided in the tank body 3, and two second rotating rods 601 are symmetrically arranged on both sides of the first rotating rod 501. side, and two second rotating rods 601 are provided with three second stirring blades 602, two first stirring blades 502 and six second stirring blades 602 are staggered, through two first stirring blades 502 and six The rotation of the second stirring blade 602 can further enhance the mixing speed a...

Embodiment 3

[0042] see Figure 1-7 , the second mixing mechanism 6 also includes a first gear 603 arranged on the first rotating rod 501, a second gear 604 is arranged on the two second rotating rods 601, the first gear 603 and the two second gears 604 are both engage.

[0043] In this embodiment: in order to realize the operation of driving the second mixing mechanism 6, when the first rotating rod 501 rotates, the first gear 603 will also rotate together, and then drive the two second gears 604 to rotate, and the two second gears 604 will drive the two second rotating rods 601 to rotate, so that when the first mixing mechanism 5 is in operation, the second mixing mechanism 6 will operate passively without further driving.

Abstract

The invention relates to the technical field of medical instruments, and discloses nephrology department hemodialysis equipment which comprises a dialysis machine, a blood detector and a tank are arranged on the dialysis machine, a plurality of feeding pipelines are arranged on the tank, and electromagnetic valves are arranged in the feeding pipelines. According to the hemodialysis equipment for the nephrology department, when blood of a patient is input into the hemodialysis machine through the blood detector, the blood of the patient can be detected, specific components of dialysate needing to be prepared are calculated according to data, then the specific content of the input components is controlled through the three electromagnetic valves, and after all the components are injected into the tank body, the blood of the patient is detected. The components are mixed through the first mixing mechanism and the second mixing mechanism so that dialysate can be formed, then the dialysate is evenly injected into the dialysis machine through operation of the infusion mechanism to be subjected to the dialysis process, and therefore the dialysate can be prepared on site according to the blood concentration of a patient, needed basic groups, electrolyte and other specific conditions in the dialysis process. Therefore, the optimal dialysis curative effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to hemodialysis equipment for nephrology. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. The whole process of exchanging substances with the principle of convection, removing metabolic waste in the body, maintaining electrolyte and acid-base balance; at the same time removing excess water in the body, and returning the purified blood is called hemodialysis. Dialysate is a solution with a concentration close to that of blood electrolytes. In order to maintain normal electrolyte levels, it provides bases to the body through a higher base concentration to correct the acidosis in patients. The commonly used dialysate base is mainly bicarbonate, and also cont...
