Description

Technical Field

[0002] A quantitative instrument for cardiovascular pharmacology experiments was developed against the background of the increasing importance of cardiovascular disease research and the rising incidence rate. With the trend of younger people suffering from cardiovascular and cerebrovascular diseases and the enhancement of public health awareness, the demand for cardiovascular pharmacology experiments is growing. This quantitative instrument is designed to improve the accuracy of experimental drug preparation, thereby increasing the success rate of experiments and providing strong support for the treatment and research of cardiovascular diseases. It not only helps researchers to deeply understand the mechanism of action of drugs on the cardiovascular system, but also provides reliable experimental tools for the development of new cardiovascular drugs. With the continuous advancement of technology, this quantitative instrument is gradually becoming intelligent, automated and precise to meet the higher needs of scientific research and clinical practice.

[0003] After searching, the Chinese patent number CN218590564U discloses a quantitative instrument for pharmacological experiments, including a placing table, a pillar, a medicine cartridge and a piston pressing assembly. The pillar is arranged on the side wall of the placing table, the side wall of the medicine cartridge is provided with a fixed column, the fixed column is arranged on the side wall of the pillar, a piston is arranged in the medicine cartridge, and the piston pressing assembly is arranged on the pillar; the piston pressing assembly includes a screw, a screw pair, an active bevel gear and a driven bevel gear, the side wall of the pillar is provided with a slideway, both ends of the screw are slidably arranged on the slideway, the screw pair is threadedly connected to the screw and slidably arranged on the slideway, the bottom end of the screw pair is provided with a connecting rod, the bottom end of the connecting rod is connected to the top wall of the piston, the top wall of the placing table is provided with a placing groove, the active bevel gear is rotatably arranged on the side wall of the slideway, the driven bevel gear is fixedly sleeved on the screw, and the active bevel gear and the driven bevel gear are meshed. Compared with the prior art, the Chinese patent number CN218590564U solves the problem that when operating the prior art equipment, the worker has to manually rotate the turntable while observing the content of the solution in the test tube at the same time. During this operation, it is impossible to ensure that the worker's line of sight can be level and directly look at the scale on the test tube, which is prone to deviation.

[0004] However, in actual use of the above device, when using the device to prepare the drug solution, the personnel need to observe the drug solution in the test tube while manually controlling the dripping of the drug solution, which can easily lead to more or less drug solution dripping during the operation, resulting in quantitative deviations and affecting the accuracy of the pharmacological experiment.

[0034] The control mechanism can control the internal movable baffle 21 to rotate and control the opening and closing of the piston 19. The upper part of the drug pushing mechanism is fixedly connected to the test bench 3. The upper part of the test bench 3 is provided with a clamping mechanism. The clamping mechanism drives the clamps 7 provided on both sides to close and fix the test tube 4 placed in the middle. The test tube 4 is located directly below the drug adding barrel 1.

[0035] The medicine pushing mechanism includes a medicine adding shell 5 fixedly connected to the upper part of the test bench 3, a second motor 14 is arranged on the upper part of the medicine adding shell 5, a medicine pushing assembly is arranged at the output end of the second motor 14, and the medicine pushing assembly includes a screw rod 15 arranged at the output end of the second motor 14, the screw rod 15 is rotatably connected to the medicine adding shell 5, the screw rod 15 is threadedly connected to a transmission plate 18, a piston 19 is fixedly connected to the lower part of the transmission plate 18, the piston 19 is slidably connected to the medicine adding barrel 1, and the rear end of the transmission plate 18 is rotatably connected to two rotating wheels 17, a limit plate 16 is arranged at the middle position of the rotating wheel 17, and the limit plate 16 is fixedly connected to the medicine adding shell 5;
