Description

[0001] The invention belongs to the technical field of pharmaceutical powder preparation sampling, and in particular relates to a multi-sampling device for clinical pharmaceutical powder preparations. Background Art

[0002] Clinical pharmacy is a pharmaceutical discipline that studies the rationality and effectiveness of drug-based prevention and treatment. It primarily examines the theories and methods that enable drugs to achieve their highest efficacy during their metabolism within the human body. It focuses on the relationship between drugs and humans, directly interfering with the drugs themselves, the recipients of medication, and the methods of administration, and therefore, directly impacting the quality of healthcare.

[0003] At present, in the process of clinical pharmaceutical research, it is often necessary to use a spoon to sample powdered medicines for experimental research, etc., but it is very inconvenient to use a spoon to take powdered medicines. Some people use sampling devices to sample powdered medicines, but the existing sampling devices are complicated to operate. If they are not operated properly, the pharmaceutical powder preparations may easily splash into the eyes and ears, causing harm to the staff. At the same time, the existing sampling devices have relatively single functions. When it is necessary to sample multiple powdered medicines, after sampling one medicine, it needs to be cleaned to prevent the medicine adhering to it from mixing into other medicine bottles and causing contamination of the medicine. It is more troublesome to use, which affects the sampling and use of powdered medicines.

[0021] In the above structure, the lifting plate 5 is conveniently adjusted to move up and down by the threaded cooperation with the screw rod 4. Combined with the lifting rod 6, the sampling tube 7 is driven to move up and down synchronously along the inner cavity of the cylinder body 3. Under the action of the cone head 8, it is convenient to drive the sampling tube 7 to be inserted into the powder preparation required for sampling to implement the sampling operation.

A cover plate 15 is fixedly sleeved on the side of the outer wall of the delivery pipe 14 away from the sampling tube 7, and a sampling bottle 16 is threaded on the inner wall of the cover plate 15.

[0023] The motor 10 is used to drive the rotating shaft 11 to rotate, thereby driving the spiral blade 12 to rotate synchronously. Under the action of the sampling port 13, the powdered preparation is easily extracted and transported to the delivery tube 14 through the inner cavity of the sampling cylinder 7. Combined with the inclined setting of the delivery tube 14, the extracted powdered preparation can slide along the delivery tube 14 into the sampling bottle 16 to complete the sampling of the powdered preparation. The sampling bottle 16 is threaded with the cover plate 15 to facilitate the subsequent use of the sampled powdered preparation.

[0024] The first adjustment component includes a rotating rod 17, which is rotatably embedded in the top of the cover 1. A first gear 18 is provided in the cover 1. The first gear 18 is fixedly sleeved on the lower side of the outer wall of the rotating rod 17. A second gear 19 is fixedly sleeved on the upper side of the outer wall of the cylinder 3. The first gear 18 is meshed with the second gear 19. A top plate 20 is fixed to the upper end of the rotating rod 17. A movable rod 21 is movably provided on the top plate 20. A rubber pad 22 is fixed to the lower end of the movable rod 21. The rubber pad 22 cooperates with the top surface of the cover 1. A first spring 23 is connected between the top of the rubber pad 22 and the top plate 20. The first spring 23 is sleeved on the outside of the movable rod 21. The first gear 18 is adjusted to rotate by the rotating rod 17. Under the meshing action of the first gear 18 and the second gear 19, combined with the rotation cooperation of the movable ring 2 and the cover 1, the plurality of cylinders 3 are driven to rotate around the rotating rod 17, thereby driving the sampling barrels 7 to move synchronously, so that the plurality of sampling barrels 7 can sample different powdered preparations respectively. Under the elastic action of the first spring 23, combined with the movable cooperation of the movable rod 21 and the top plate 20, the rubber pad 22 is squeezed downward until the rubber pad 22 fits with the top of the cover 1, thereby achieving the purpose of limiting the rotating rod 17, and then achieving the purpose of limiting and fixing the first gear 18, avoiding the first gear 18 from rotating freely and driving the movable ring 2 to move, thereby ensuring the stability of the sampling barrel 7 during the sampling process.

[0025] The second adjustment component includes a fixed block 24, the upper end of the screw rod 4 passes through the fixed plate on the upper side and is fixedly connected to the fixed block 24, a cross slot 25 is provided on the top of the fixed block 24, and an L-shaped fixed rod 26 is provided on the front side of the top of the cover 1 through the damping shaft. The transverse part of the fixed rod 26 is penetrated and embedded with a piston rod 27, and the piston rod 27 is movably matched with the fixed rod 26. A fixed plate 28 is fixed to the lower end of the piston rod 27, and a cross block 29 is fixed to the bottom of the fixed plate 28. The cross block 29 cooperates with the cross slot 25. A knob is fixed to the upper end of the piston rod 27, and a second sleeve is provided on the outer side of the piston rod 27. The spring 30 and the second spring 30 are arranged between the fixed disk 28 and the fixed rod 26, and the second spring 30 is not connected to the fixed disk 28 and the fixed rod 26. The fixed rod 26 is rotated with the cover 1 to facilitate the adjustment of the fixed rod 26 for rotation until the piston rod 27 is driven to move to the top of the cylinder 3 on the front side. The active cooperation between the piston rod 27 and the fixed rod 26, combined with the elastic action of the second spring 30, facilitates the downward squeezing of the fixed disk 28, thereby driving the cross block 29 to be inserted into the corresponding cross slot 25, making it convenient to adjust the screw rod 4 for rotation, thereby facilitating subsequent sampling operations.

[0026] A pointer 31 is fixed on the upper side of the outer wall of the cylinder 3, and a centering line 32 is opened on the top of the cover shell 1. The pointer 31 and the centering line 32 cooperate with each other to facilitate the control of the rotation angle of the movable ring 2, ensuring that the cylinder 3 on the front side can stay in the appropriate position, and ensuring that the subsequent adjustment cross card block 29 is inserted into the corresponding cross card slot 25, which is convenient for subsequent sampling operations.

[0027] A movable door 33 is installed on one side of the surface of the cover shell 1 through a hinge, and a transparent plate 34 is provided on the movable door 33. Two grips are relatively fixed to the outer wall of the cover shell 1. The sampling bottle 16 is a transparent glass bottle. The transparent plate 34, combined with the transparent material of the sampling bottle 16, makes it convenient to watch the sampling progress in real time. Several U-shaped rods are arranged across the outside of the movable ring 2, and the U-shaped rods are fixed to the top of the cover shell 1.

[0028] Example: In the process of clinical pharmaceutical research, when it is necessary to sample powdered medicines, the cover 1 is first adjusted to the upper side of the powdered preparation storage bottle to be sampled under the action of the grip, and the bottom of the cover 1 is pressed against the outer wall of the upper port of the powdered preparation storage bottle. Then, under the active cooperation of the movable rod 21 and the top plate 20, the movable rod 21 is pulled upward to drive the rubber pad 22 away from the top surface of the cover 1 and squeeze the first spring 23. Through the movable rod 21 and the top plate 20, the rotating rod 17 is driven to rotate. As the rotating rod 17 rotates, the rubber pad 22 is driven to rotate. The first gear 18 rotates, and under the meshing action of the first gear 18 and the second gear 19, combined with the rotational cooperation of the movable ring 2 and the cover 1, the plurality of cylinders 3 are driven to rotate around the rotating rod 17 until the pointer 31 on the cylinder 3 is aligned with the center line 32. At this time, the movable rod 21 is released, and under the elastic action of the first spring 23, the rubber pad 22 is squeezed downward until the rubber pad 22 is in contact with the top of the cover 1, thereby limiting the rotating rod 17 and further limiting and fixing the first gear 18. Secondly, by rotating the fixing rod 26 and the cover 1, the fixing rod 26 is adjusted to rotate until the piston rod 27 is moved to the top of the cylinder 3 on the front side. Under the active cooperation of the piston rod 27 and the fixing rod 26, combined with the elastic action of the second spring 30, the fixing plate 28 is pressed downward, driving the cross block 29 to be inserted into the cross slot 25 on the lower side. At this time, the knob on the upper end of the piston rod 27 is turned. Under the mutual cooperation of the cross block 29 and the cross slot 25, the screw rod 4 is adjusted to rotate. Combined with the threaded cooperation of the lifting plate 5 and the screw rod 4, the lifting plate 5 is adjusted to move downward. In cooperation with the lifting rod 6, the sampling tube 7 is driven to move downward along the inner cavity of the cylinder 3. Under the action of the cone head 8, the sampling tube 7 is driven to be inserted into the powdered preparation to be sampled; At this time, the motor 10 is started, and the rotating shaft 11 is driven by the motor 10 to rotate, thereby driving the spiral blade 12 to rotate synchronously. Under the action of the sampling port 13, the powdered preparation is extracted and transported to the delivery tube 14 through the inner cavity of the sampling cylinder 7. Combined with the inclined setting of the delivery tube 14, the extracted powdered preparation slides along the delivery tube 14 into the sampling bottle 16, completing the sampling of the powdered preparation. The threaded fit between the sampling bottle 16 and the cover plate 15 facilitates the subsequent use of the sampled powdered preparation, thereby solving the problem that in the process of clinical pharmaceutical research, a spoon is often needed to be used to sample powdered medicines for experimental research, etc., but it is very inconvenient to use a spoon to take powdered medicine. The cover 1 is arranged on the outside of the sampling tube 7 to play an isolating role, effectively preventing the powder preparation from splashing during the sampling process and causing harm to the staff, thereby solving the problem that some sampling devices are used to sample powdered medicines, but the existing sampling devices are complicated to operate and are prone to splashing pharmaceutical powder preparations into the eyes and ears when operated improperly, causing harm to the staff; During the sampling process, the sampling progress is monitored in real time through the transparent plate 34 in combination with the transparent material of the sampling bottle 16. After the sampling is completed, the sampling cylinder 7 is adjusted to move upward until the sampling port 13 moves to the upper side of the powdered preparation, and the driving motor 10 rotates in the reverse direction to discharge the powdered preparation remaining in the sampling cylinder 7. The sampling cylinder 7 is then adjusted to move upward to the initial position. After sampling one powder preparation, when it is necessary to sample multiple powder preparations, the above steps are reversed to adjust the cross block 29 to disengage from the corresponding cross slot 25, and repeat the above operation of adjusting the rotating rod 17 until the next cylinder 3 moves to the front side, and continue to repeat the above operation to sample another powder preparation. This solves the problem that the existing sampling device has a relatively single function and needs to be cleaned after sampling one medicine when multiple powder preparations need to be sampled to prevent the medicine adhering to it from mixing into other medicine bottles, causing contamination of the medicine, and is more troublesome to use, which affects the sampling and use of powder preparations.

[0029] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the motor 10 in the present invention is purchased on the market, and technical personnel in this field can install and use it according to requirements.
