Problems solved by technology

[0003] During hemodialysis, the blood is drawn out of the body, passes through the dialysis device to the dialysis machine, to the dialyzer, and then returns to the human body. At this time, the blood circulates outside the body, prone to prothrombin generation and fibrin deposition, which easily cause blood coagulation , seriously affecting the effect of hemodialysis
[0004] Therefore, it is often necessary to add anticoagulant to the dialyzer before dialysis for preflushing, and add heparin treatment during dialysis, but the use of heparin will cause damage to the patient's liver, kidney and heart function

Embodiment 1

[0035] An instrument for preventing blood coagulation in hemodialysis, comprising an instrument body 1 and a support shell 2 for installing the instrument body 1, the top of the support shell 2 is fixedly connected with an installation base 3, and the instrument body 1 is installed and fixed in the installation base 3, The instrument body 1 includes an operation table 4 and an anti-coagulation power assembly 5, and the anti-coagulation power assembly 5 and the operation table 4 are connected by a connection line 6, and also includes:

[0036] The moving mechanism 7, the moving mechanism 7 is arranged in the inner cavity of the supporting shell 2, and is used to improve the mobility of the instrument body 1;

[0037] Lifting mechanism 8, the lifting mechanism 8 is arranged in the inner cavity of the supporting shell 2, and is used to drive the moving mechanism 7 to lift;

[0038] A driving mechanism 9, the driving mechanism 9 is arranged on one side of the lifting mechanism 8, ...

Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that: the bottom of the horizontal plate 23 is fixedly connected with a U-shaped supporting plate 39, the servo motor 25 is installed and fixed in the U-shaped supporting plate 39, and the rear end surface of the supporting shell 2 is fixed. It is connected with a push handle 40 for conveniently pushing the support shell 2, and the surface of the push handle 40 is provided with a latex anti-slip sleeve. In the inner cavity of the support shell 2, two stable plates 41 are fixedly connected, and two threaded rods 24 are used in principle. One end of the disc 27 is respectively connected to two stable plates 41 in rotation; the setting of the U-shaped support plate 39 can effectively support the servo motor 25, improve the running stability of the servo motor 25, and prevent it from falling during use. The setting of the push handle 40 can facilitate the promotion of the hemodialysis anticoagulation instrument, and ...

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, in particular to an instrument for preventing blood coagulation in hemodialysis. 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. [0003] During hemodialysis, the blood is drawn out of the body, passes through the dialysis device to the dialysis machine, to the dialyzer, and then returns to the human body. At this time, the blood circulates outside the body, prone to prothrombin generation and fibrin d...
