Embodiment 1

[0024] When it is necessary to control the blood temperature and flow rate, after connecting the venous needle 1 and the arterial needle 5 to the human vein and artery respectively, close the valve A22 and the valve B42, turn on the inlet pump A21 and the outlet pump B41, and the blood enters from the venous needle 1→ Liquid pipe 2 → liquid inlet pump A21 → hemodialysis device 3 → liquid outlet pipe 4 → liquid outlet pump B41 → blood sensor 45 → arterial needle 5, return to the body, and circulate repeatedly.

Embodiment 2

[0026] When it is necessary to control the blood temperature, connect the venous needle 1 and the arterial needle 5 to the human veins and arteries respectively, then turn off the inlet pump A21 and the outlet pump B41, the blood is driven by the heart, and the arterial needle 5 → the inlet tube 2→Valve A22→Hemodialysis device 3→Outlet pipe 4→Valve B42→Blood sensor 45→Venous needle 1, return to the body, and circulate repeatedly.

Embodiment 3

[0028] While carrying out Embodiment 1 or 2, when other medicaments need to be injected, the valve C44 can be opened to inject from the liquid filling port 43 at a certain speed.

Abstract

The invention relates to the field of medical instruments, in particular to a renal medicine hemodialysis device. The renal medicine hemodialysis device comprises a vein syringe needle, a liquid-in pipe, a hemodialysis device body, a liquid-out pipe, an artery syringe needle and a control cabinet. A liquid-in pump A and a valve A are connected to the liquid-in pipe, the liquid-in pump A and the valve A are connected in parallel, a liquid-out pump B and a valve B are connected to the liquid-out pipe, the liquid-out pump B and the valve B are connected in parallel, a liquid feeding opening is connected to a liquid-out pipe branch, a valve C is arranged between a liquid feeding opening connection pipe and the liquid-out pipe, the hemodialysis device body is provided with a heating and heat preservation jacket, the heating and heat preservation jacket is provided with a temperature sensor, and a blood sensor is connected to the liquid-out pipe between the artery syringe needle and the liquid-out pump B. According to the renal medicine hemodialysis device, the temperature sensor, the blood sensor, the liquid-in pump A, the liquid-out pump B, a touch screen, a mobile phone or a notebook computer are configured, technical parameters of blood, including the temperature, flow velocity and blood constituents can be set, controlled and displayed, remote control is achieved, and it is convenient to conduct clinical recording and research.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hemodialysis device for nephrology. Background technique [0002] Nephrology hemodialysis device is a commonly used medical device for detoxification of blood. It acts as an artificial kidney. It has a semi-permeable membrane inside, and the semi-permeable membrane only allows small molecules and some middle molecules with a molecular weight of less than 15,000. Substances pass through, but macromolecular substances with a molecular weight greater than 35,000 cannot pass through. Therefore, proteins, pyrogens, viruses, bacteria, and blood cells are all impenetrable; most of the components of urine are water. If you want to use an artificial kidney To replace the kidney, a large amount of water must be discharged from the blood. The artificial kidney can only use osmotic pressure and ultrafiltration pressure to remove excess water. The artificial kidney used, that is, the hemodial...
