[0023] Xuesaitong Capsule is a traditional Chinese medicine preparation, and its main ingredients are usually active ingredients extracted from traditional Chinese medicines such as Panax notoginseng and Salvia miltiorrhiza. This medicine is mainly used for the adjuvant treatment of cardiovascular diseases, such as improving coronary circulation, preventing and treating angina pectoris, etc.
[0024] The production process of Xuesaitong Capsule mainly includes raw material extraction, preparation processing, quality control, packaging and labeling. Among them, raw material selection includes: selecting high-quality Panax notoginseng as the raw material to ensure the quality and purity of the medicinal materials. Extraction process: Modern extraction techniques such as water extraction, alcohol extraction, or supercritical fluid extraction are used to extract the total saponin components in Panax notoginseng. Concentration and purification: The extracted liquid is concentrated, and the effective components are further purified by methods such as column chromatography to remove impurities and increase the concentration of the effective components. In this process, a spotting instrument is needed to detect the components of the liquid medicine.
[0025] Example
[0026] As Figures 1-6 , a pipetting device of a semi-automatic spotting instrument for the production of Xuesaitong Capsule, includes a pipette gun 1 and a pipetting platform 2.
[0027] Among them, the pipetting platform 2 mainly functions to fix the pipette gun 1 and drive the pipette gun 1 to move, and includes a fixed carrier: used to locate the position of the pipette tip, which can move on the XY axis to accurately position the pipette tip at the target position; a control system: including software and hardware, used for programming and controlling the pipetting process.
[0028] The pipette gun 1 is detachably mounted on the pipetting platform 2 , and its detachable connection method is the same as the existing method of installing the pipette gun into a semi-automatic spotting instrument, and the present application does not make any improvement thereto.
[0029] The pipette gun 1 comprises a gun barrel 11, a half rod 12, an opening and closing rod 13, a limiting sleeve 14 and an end plate 15. A visual window is provided on the side wall of the gun barrel 11. A sealing plate is slidably connected in a closed manner inside the gun barrel 11. The sealing plate and the half rod 12 are fixedly connected. One end of the gun barrel 11 away from the half rod 12 extends outward to form a gun nozzle. When in use, the user pulls the half rod 12 to allow the half rod 12 to drive the sealing plate to move, and the liquid medicine is drawn into the gun barrel 11 under the action of air pressure.
[0030] Three opening and closing rods 13 are hinged on the half rod 12. The three opening and closing rods 13 are radially extended outward with the axis of the half rod 12 as the center. The three are just examples and are not intended to be limiting.
[0031] The closed opening and closing rod 13 can enter the cavity of the gun barrel 11 and will not interfere with the gun barrel 11 when moving. The opened opening and closing rod 13 can facilitate the user to apply force to drive the sealing plate to move by pulling the opening and closing rod 13.
[0032] The limiting sleeve 14 is used to be sleeved on the outside of the closed opening and closing rod 13 .
[0033] The limiting sleeve 14 is fixedly connected to the end plate 15 , and the end plate 15 is used to be squeezed by the upper, middle and lower moving parts of the liquid transfer platform 2 so as to squeeze the liquid medicine in the liquid transfer gun 1 out of the gun nozzle.
[0034] The working principle of this embodiment is as follows: by dividing the push rod into two parts, a half rod 12 and an opening and closing rod 13, the opening and closing rod 13 has an expandable characteristic, which reduces the length of the push rod on the axis of the barrel 11, and the opening and closing rod 13 does not hinder the user from pulling the half rod 12 when expanded, thereby reducing the degree of hand shaking of the user when sucking the medicine liquid.
[0035] Specifically, the opening and closing rod 13 is placed between the user's fingers, and the user's palm grasps the hinge of the half rod 12 and the opening and closing rod 13, so that the user can apply force. When the half rod 12 and the opening and closing rod 13 need to be pulled out of the gun barrel 11, the following design is used: the top of the opening and closing rod 13 extends outward to form a grippable handle end, and the handle end is always located outside the gun barrel 11 to facilitate the user to apply force. In this case, the limiting sleeve 14 can be sleeved on the outside of the handle end.
[0036] Preferably, adjacent opening and closing rods 13 are connected by two connecting rods 16, and the two connecting rods 16 are movably connected by ball bearings. The two ends of the two connecting rods 16 are movably connected to the corresponding opening and closing rods 13 through ball bearings respectively. A clearance groove is provided in the opening and closing rod 13. When several opening and closing rods 13 are closed, the two connecting rods 16 are folded and retracted into the clearance groove, thereby reducing the interference of the connecting rods 16 on the opening and closing rods 13.
[0037] The design of the connecting rod 16 can limit the excessive expansion of the opening and closing rod 13 .
[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
[0039] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
