Problems solved by technology

[0005] In the prior art, the nutritional analyzer and the hemodialysis instrument are placed separately, and the patient needs both intubation for dialysis and needing a needle to draw blood. Nutritional analysis can be carried out at the same time, which can reduce the number of needle injections, reduce the pain of patients, and reduce the infection rate

Embodiment 1

[0044] A traditional hemodialysis machine includes a liquid inlet pipe 1 and a liquid outlet pipe 2. The patient's blood enters the hemodialysis machine through the liquid inlet pipe 1, and flows into the patient's body through the liquid outlet pipe 2 after purification to complete the blood purification process.

[0045] The present invention provides a special nutritional analysis device for chronic renal failure secondary hyperparathyroidism. A shunt device is installed on the liquid inlet pipe 1. The shunt device can shunt part of the blood and pass it to the nutrition analyzer body 3. for analysis. The nutrition analyzer body 3 adopts the brand of the prior art, aiming to realize the analysis of blood nutrients. Therefore, the device provided by the present invention can be used in patients undergoing dialysis, which can reduce the number of needle sticks for patients, reduce the suffering of patients, and reduce the infection rate.

[0046] The flow distribution device...

Embodiment 2

[0055] A dedicated nutritional analysis device for chronic renal failure secondary hyperparathyroidism, which has basically the same structure as that of Example 1, the difference is that the extrusion block drive assembly includes a telescopic rod 501, a controller 502, and a housing switch 503, The movable end of the telescopic rod 501 is fixedly connected with the extrusion block 51, the fixed end of the telescopic rod 501 penetrates and is fixedly connected to the inner top wall of the hollow box body 431, and the top outer wall of the hollow box body 431 A controller 502 for controlling the operation of the telescopic rod 501 is installed, and a shell switch 503 is installed on the outer wall of the hollow box body 431, and the controller 502 is electrically connected with the telescopic rod 501 and the shell switch 503 respectively. The controller 502 is also connected to a power source. By operating the housing switch 503, the telescopic rod 501 can drive the extruding ...

Embodiment 3

[0058] A dedicated nutritional analysis device for chronic renal failure secondary hyperparathyroidism, basically the same structure as in Example 1, the difference lies in the branch pipe 433 and the connection between the branch pipe 433 and the branch pipe 433 There is a blood anticoagulant filling body 435 inside. Due to the limited number of samples taken for nutritional analysis during the dialysis process, the blood anticoagulant filling body 435 can prevent blood coagulation for smooth sampling.

[0059] Preferably, the blood anticoagulant filling body 435 is divided into a hose segment 6 and two hard tube segments 7 connected to both ends of the hose segment 6 , the position of the hose segment 6 is in line with that of the extruding block 51 Corresponding positions, when the extruding block 51 extrudes the branch pipe 433, the hose segment 6 and its internal filling can be extruded at the same time, and after the extruding block 51 squeezes the branch pipe 433, The h...

Abstract

The invention belongs to the technical field of medical detection equipment, and particularly relates to a special nutrition analysis device for chronic renal failure secondary hyperparathyroidism. The device comprises a flow dividing device, wherein the flow dividing device is used for being arranged on a liquid inlet pipe of a hemodialysis instrument; the flow dividing device comprises a sampleinlet pipe, a sample outlet pipe, a flow dividing pipe and a flow rectifying box; the flow rectifying box comprises a hollow box body; a three-way pipe is arranged in the hollow box body; three portsof the three-way pipe are detachably communicated with one end of the sample inlet pipe, one end of the sample outlet pipe and one end of the flow dividing pipe; the other end of the sample inlet pipeand the other end of the sample outlet pipe are communicated with the liquid inlet pipe; the other end of the flow dividing pipe is used for being connected with a sample inlet of a nutrition analyzer body; a control assembly capable of controlling whether blood circulation exists or not is arranged on one section of pipe, connected with the flow dividing pipe, on the three-way pipe; and a control switch of the control assembly is arranged on the hollow box body. The device has the advantages that the nutrition analysis can be performed during the dialysis of a patient; the needle inserting times of the patient can be reduced; the pain of the patient is reduced; and the infection rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical detection equipment, and in particular relates to a special nutritional analysis device for chronic renal failure secondary hyperparathyroidism. Background technique [0002] Chronic renal failure (CRF) refers to chronic progressive renal parenchymal damage caused by various reasons, resulting in obvious atrophy of the kidneys, unable to maintain basic functions, clinical manifestations of retention of metabolites, and imbalance of water, electrolytes, and acid-base balance. The renal function of patients with chronic renal failure often meets their own metabolic needs, so regular hemodialysis is required. [0003] Chronic renal failure secondary hyperparathyroidism mainly refers to that in the case of chronic renal insufficiency, the parathyroid glands are stimulated by hypocalcemia, hypomagnesemia or hyperphosphatemia for a long time to secrete excessive PTH to improve A chronic compensatory cl...
