Description

Technical Field

[0002] Heparin sodium is an anticoagulant with strong negatively charged physicochemical properties. It can interfere with multiple steps of blood coagulation and has anticoagulant effects both in vivo and in vitro. Its anticoagulant mechanism is relatively complex. It mainly works by binding to antithrombin III, thereby inhibiting activated coagulation factors.

[0003] Chinese patent document CN222342155U discloses a purification mechanism for heparin sodium, belonging to the field of heparin sodium technology. It includes a stirring tank, a filter box located on the outside of the stirring tank, a water storage tank fixedly connected to the upper surface of the filter box, and a water pump fixedly connected to the upper surface of the filter box. The input end of the water pump's power passes through the water storage tank and extends into its interior, while the output end of the water pump passes through the filter box and extends into its interior. The output end of the water pump's power is fixedly connected to a water outlet pipe. This purification mechanism for heparin sodium, by incorporating a miniature reversible motor, a threaded rod, a moving plate, and a cleaning plate, provides the power required for cleaning under the action of the miniature reversible motor. The rotation of the miniature reversible motor drives the threaded rod to rotate, which in turn drives the moving plate and the cleaning plate to move, thereby cleaning impurities adsorbed on the filter plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-3 An embodiment of this utility model provides a purification mechanism for heparin sodium, comprising a centrifuge tank 2, one end of which is sealed to a membrane separation chamber 5 via a pipeline, the membrane separation chamber 5 is sealed to a heating chamber 8 via a pipeline, the heating chamber 8 is sealed to a condenser chamber 17 via a hot gas delivery pipe 15, a liquid collection funnel 18 is installed at the bottom of the condenser chamber 17, and the liquid collection funnel 18 is connected to a liquid collection box 19 via a pipeline.

[0021] Furthermore, a centrifugal motor 1 is installed on the top of the centrifuge tank 2. The output end of the centrifugal motor 1 is fixedly connected to a centrifugal stirring rod 9 via a rotating shaft 10. By turning on the centrifugal motor 1, the rotating shaft 10 is driven to rotate the centrifugal stirring rod 9 at high speed, thereby pre-centrifuging and stirring the heparin sodium solution inside the centrifuge tank 2, which can precipitate some impurities to the bottom of the centrifuge tank 2.

[0022] Furthermore, the membrane separation chamber 5 is equipped with a primary filtration membrane 11, an ultrafiltration membrane 12, and a nanofiltration membrane 13. The pore size of the primary filtration membrane 11 is larger than that of the ultrafiltration membrane 12, and the pore size of the nanofiltration membrane 13 is smaller than that of the ultrafiltration membrane 12. By layering the primary filtration membrane 11, ultrafiltration membrane 12, and nanofiltration membrane 13, the membrane filtration structure can further filter and remove tiny impurities in the heparin sodium solution, ensuring the high purity of the heparin sodium solution.

[0023] Furthermore, an electric heating pipe 14 is installed inside the heating chamber 8. The electric heating pipe 14 can be used to heat the heparin sodium solution entering the heating chamber 8, causing it to generate water vapor. A condenser pipe 16 is installed inside the condenser chamber 17. The condenser pipe 16 can condense and liquefy the water vapor entering the condenser chamber 17 into water.

[0024] Furthermore, the centrifuge tank 2 and the membrane separation chamber 5 are connected by a first infusion pipe 4. A first filtrate pump 3 is installed on the first infusion pipe 4. By turning on the first filtrate pump 3, the solution after centrifugation and filtration inside the centrifuge tank 2 can be drawn into the membrane separation chamber 5 through the first infusion pipe 4.

[0025] Furthermore, the membrane separation chamber 5 and the heating chamber 8 are connected by a second infusion pipe 7. A second filtrate pump 6 is installed on the second infusion pipe 7. By turning on the second filtrate pump 6, the solution filtered inside the membrane separation chamber 5 can be sent into the heating chamber 8 through the second infusion pipe 7.

[0026] Furthermore, the condenser tube 16 is used to liquefy the hot steam entering the condenser chamber 17 into water and collect and store it in the liquid collection box 19, thereby achieving a good purification effect on the heparin sodium solution.

[0027] Working principle: During use, the centrifugal motor 1 is turned on to drive the control shaft 10, which in turn drives the centrifugal stirring rod 9 to rotate rapidly. This pre-centrifuges and stirs the heparin sodium solution inside the centrifuge tank 2, allowing some impurities to settle to the bottom of the centrifuge tank 2. By turning on the first filtrate pump 3, the centrifuged and filtered solution inside the centrifuge tank 2 is drawn into the membrane separation chamber 5 through the first infusion pipe 4. The membrane separation chamber 5 is equipped with a primary filtration membrane 11, an ultrafiltration membrane 12, and a nanofiltration membrane 13. Through the layered arrangement of the primary filtration membrane 11, ultrafiltration membrane 12, and nanofiltration membrane 13, the membrane filtration structure can effectively filter the heparin sodium solution. Tiny impurities in the solution are further removed through layer-by-layer filtration to ensure high purity of the heparin sodium solution. By turning on the second filtrate pump 6, the solution filtered inside the membrane separation chamber 5 can be sent to the interior of the heating chamber 8 via the second infusion pipe 7. The heating chamber 8 is equipped with an electric heating pipe 14, which can be used to heat the heparin sodium solution entering the heating chamber 8, causing it to generate water vapor. The condenser chamber 17 is equipped with a condenser pipe 16, which can condense and liquefy the water vapor entering the condenser chamber 17 into water and store it in the collection box 19, achieving a good purification effect.
