Description

Technical Field

[0001] The invention relates to the technical field of drug grinding, in particular to a device for grinding anesthetic drugs. Background Art

[0002] Grinding of drugs can effectively improve their solubility, absorbability and bioavailability, ensure that drug ingredients are evenly distributed in the preparation, reduce side effects, facilitate the preparation of different dosage forms, improve drug stability, reduce administration volume, and adapt to the needs of special patient groups, thereby ensuring the effectiveness and safety of drugs while improving the convenience of medication for patients; and due to their precise dosage requirements, the grinding method of anesthetic drugs requires more stringent control to ensure the safety, effectiveness and uniformity of the drugs.

[0003] After searching, the Chinese patent with the publication (announcement) number CN118002285B includes a shell; a feed port is arranged on the top of the shell and a discharge port is arranged on the bottom; a grinding mechanism is arranged inside the shell and used to grind the medicine; a toggle mechanism is arranged on the grinding mechanism, and the medicine inside the grinding mechanism will be toggled along with the movement during the operation of the grinding mechanism; a purge mechanism is arranged inside the grinding mechanism and used to blow away the particles generated during the grinding process. When the rotating shaft is driven clockwise by the driving motor and the output shaft, the grinding blades will also rotate clockwise. During the rotation of the grinding blades, along the direction of rotation, the toggle wheel is in front of the pressing roller, and the toggle wheel toggles the medicine sticking to the wall on the inner wall of the conical cavity, and the pressing roller that follows it re-rolls the new medicine, thereby improving the uniformity of the grinding effect.

[0004] However, in the above-mentioned patent, the process of crushing the drug only by pressing the roller, the rigid contact between the roller and the drug can easily cause the drug to fly away, affecting the grinding process and also causing the grinding effect of the equipment to be reduced; at the same time, the drug flying away makes it difficult for the above-mentioned patent to ensure the uniformity of the grinding effect, and the change of the contact position between the drug and the pressing roller will affect its grinding degree, which leads to the device being difficult to meet the drug grinding needs when used in scenarios such as anesthetic drugs with precise grinding dosage requirements, and the above-mentioned patent cannot freely control the degree of drug grinding, which further limits the use scenarios of the device.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0032] See also Figures 1 to 9 The present invention provides a technical solution: an anesthetic drug grinding device, comprising a material storage barrel 1 and a feeding assembly inside the material storage barrel 1, a grinding assembly arranged at the bottom end of the material storage barrel 1, and a collecting assembly arranged below the grinding assembly, the top end of the material storage barrel 1 is fixedly connected with a cover plate 11, the axis of the top end of the cover plate 11 is provided with a grinding knob 12 driven by a motor, both sides of the inner contour of the material storage barrel 1 are fixedly connected with a limit rod 13, and a feeding port 14 is opened on the outer contour of the material storage barrel 1 near the top end;

[0033] The feed assembly includes a threaded sleeve 2 for controlling the grinding operation of the equipment and an adjustment mechanism for controlling the grinding degree of the equipment. The threaded sleeve 2 is located inside the storage barrel 1 and is fixedly connected to the grinding knob 12. The adjustment mechanism is transmission-connected to the threaded sleeve 2.

[0034] The collecting assembly comprises a vibration mechanism for cleaning the grinding assembly, and the vibration mechanism is transmission-connected to the grinding assembly.

[0035] In this device, the storage barrel 1 and the cover plate 11 together form a temporary storage space for drugs during grinding. The grinding knob 12 drives the device to start grinding. The limit rod 13 further limits the movement direction of the feed component, and the feed port 14 realizes manual control of drug addition.

[0036] Furthermore, before grinding begins, the medicine to be ground is added to the interior of the storage barrel 1 through the feed port 14, and then the motor is turned on to drive the grinding knob 12 to rotate. At this time, the feed component works synchronously to close the feed port 14, and at the same time pushes and squeezes the medicine to be ground inside the storage barrel 1 to make it fully contact with the grinding component, thereby avoiding the medicine flying away during the grinding process and causing a decrease in grinding quality.

[0037] At the same time, the grinding component works and crushes the medicine according to the set grinding degree. The crushed medicine powder falls into the collecting component under the guidance of the grinding component; the collecting component works synchronously to collect the ground medicine powder while continuously knocking and vibrating the grinding component to prevent medicine dust from adhering to the grinding component, thereby effectively reducing the grinding error of the equipment.

[0038] On the other hand, during the equipment resetting process, the collection component automatically exports the drug dust for easy access by personnel, and at the same time scrapes and cleans the inner wall of the collection component to further reduce the equipment grinding error caused by dust adhesion. Embodiment 2:

[0039] Please refer to 3- Figure 5 This embodiment further illustrates the following on the basis of the first embodiment:

[0040] The threaded sleeve 2 passes through the cover plate 11 and extends toward the interior of the storage barrel 1. A lifting ring 21 is screwed on the outer contour of the threaded sleeve 2, and the lifting ring 21 is slidingly connected to the limiting rod 13. An extension rod 22 passes through and is clamped on one side of the upper surface of the lifting ring 21. A baffle 23 is fixedly connected to the bottom of the extension rod 22 away from the lifting ring 21. The baffle 23 and the extension rod 22 are both slidingly connected to the interior of the storage barrel 1, and the baffle 23 is adapted to the opening size of the feed port 14.

[0041] The adjustment mechanism includes a limit ring 13 fixedly connected to the upper surface of the grinding knob 12, the inner contour of the limit ring 13 is rotatably connected to the limit ring 2 31, the top of the limit ring 2 31 is fixedly connected to the adjusting knob 32, the axis of the adjusting knob 32 is penetrated by and transmission-connected with a transmission shaft 33, the transmission shaft 33 is located inside the threaded sleeve 2 and transmission-connected with the threaded sleeve 2, a threaded portion 34 is provided on the outer contour of the top of the transmission shaft 33, and the transmission shaft 33 is threadedly connected to the adjusting knob 32 through the threaded portion 34, and a limiting portion 35 is provided on the outer contour of both sides of the bottom end of the transmission shaft 33, and the transmission shaft 33 is limitedly lifted and slidably connected with the threaded sleeve 2 through the limiting portion 35.

[0042] As can be seen from the figure, the grinding knob 12 is located outside the storage barrel 1. At this time, a driving gear fixedly connected to the motor output shaft can be added by meshing the outside of the grinding knob 12. When the motor drives the driving gear to rotate, the grinding knob 12 rotates synchronously.

[0043] When the motor is turned on and the grinding knob 12 is driven to rotate clockwise, since the threaded sleeve 2 is fixedly connected to the grinding knob 12, that is, the threaded sleeve 2 rotates synchronously clockwise, the threaded sleeve 2 tends to drive the lifting ring 21 to rotate synchronously. Since the lifting ring 21 is connected to the limiting sliding connection of the limit rod 13, the limit rod 13 is fixedly connected to the inner wall of the material storage barrel 1, and the material storage barrel 1 is in a fixed state, under the limiting action of the material storage barrel 1 and the limit rod 13, the lifting ring 21 cannot rotate with the threaded sleeve 2. At this time, the screw connection between the threaded sleeve 2 and the lifting ring 21 will cause the lifting ring 21 to gradually descend along the axis of the limit rod 13.

[0044] At the same time, since the extension rod 22 is clamped with the lifting ring 21, the extension rod 22 is fixedly connected to the baffle 23, that is, the extension rod 22 and the baffle 23 synchronously descend along with the lifting ring 21, and at this time the baffle 23 slides and descends within the internal limit of the cover plate 11; when the baffle 23 descends to the position of the feed port 14, since the baffle 23 and the feed port 14 have the same size, the baffle 23 realizes the shielding of the feed port 14 at this time, and then completes the sealing function of the feed port 14 during the grinding process to avoid excessive addition of drugs and causing obstruction of the grinding process.

[0045] Furthermore, when the baffle 23 descends to the position of the feed port 14, the feed port 14 resists the baffle 23 and prevents the baffle 23 and the extension rod 22 from continuing to descend, while the lifting ring 21 continues to descend under the continuous rotation of the grinding knob 12 and the threaded sleeve 2, thereby releasing the clamping relationship between the lifting ring 21 and the extension rod 22, and the lifting ring 21 continues to descend and gradually pushes and squeezes the to-be-ground medicine inside the storage barrel 1. The lifting ring 21 continues to descend to gradually reduce the activity space of the to-be-ground medicine inside the storage barrel 1, so that the medicine is fully in contact with the grinding assembly and avoids its flying apart during grinding, thereby effectively ensuring the grinding quality of the equipment.

[0046] After the grinding is completed, the control motor drives the grinding knob 12 to rotate counterclockwise. At this time, the movement of each structure of the feeding assembly is opposite to the above process. The counterclockwise rotation of the threaded sleeve 2 causes the lifting ring 21 to gradually rise. When the lifting ring 21 rises to the position of the feed port 14, it contacts the extension rod 22 again and further drives the extension rod 22 and the baffle 23 to rise synchronously. Then, the synchronous rise of the baffle 23 gradually removes the obstruction of the feed port 14, so that the medicine to be ground can be added to the storage barrel 1 through the feed port 14 again; when the extension rod 22 rises to contact the cover plate 11, the extension rod 22 is limited by the cover plate 11 and cannot continue to rise, while the lifting ring 21 continues to rise under the rotation of the threaded sleeve 2. At this time, the lifting ring 21 and the extension rod 22 are re-engaged and accompanied by the further rise of the lifting ring 21, the degree of engagement between the lifting ring 21 and the extension rod 22 gradually increases and reaches the maximum degree when the lifting ring 21 contacts the cover plate 11. At this time, the extension rod 22 can be lowered again with the lifting ring 21 in the subsequent re-grinding process.

[0047] It should be noted that during the grinding process, the medicine in the barrel 1 may produce debris due to the rigid contact between the barrel 1 and the threaded sleeve 2 and adhere to the inner wall of the barrel 1 and the threaded groove of the lifting ring 21. At this time, during the descent of the lifting ring 21, the medicine debris attached to the inner wall of the barrel 1 and the threaded groove of the threaded sleeve 2 can be effectively scraped and introduced into the grinding assembly, thereby effectively reducing the grinding error of the equipment.

[0048] When the grinding degree of the equipment needs to be adjusted, the grinding knob 12 is kept in a fixed state and the adjusting knob 32 is manually turned. At this time, the adjusting knob 32 has a tendency to drive the transmission shaft 33 to rotate synchronously under the action of the threaded portion 34, and the bottom end of the transmission shaft 33 is slidingly connected with the threaded sleeve 2 under the action of the limiting portion 35, and the threaded sleeve 2 is fixedly connected to the grinding knob 12. That is, at this time, the transmission shaft 33 cannot rotate under the fixing action of the threaded sleeve 2 and the limiting portion 35. Further, the rotation of the adjusting knob 32 drives the transmission shaft 33 to start to rise and fall synchronously.

[0049] It should be noted that when the adjustment knob 32 rotates to cause the transmission shaft 33 to rise and fall, the rise and fall of the transmission shaft 33 also tends to drive the adjustment knob 32 to rise and fall. Since the adjustment knob 32 is fixedly connected to the limit ring 2 31, the limit ring 2 31 and the limit ring 1 3 are rotationally connected in a limited manner, and the limit ring 1 3 is fixedly connected to the grinding knob 12, that is, the overall height of the limit ring 1 3, the limit ring 2 31 and the adjustment knob 32 is in a fixed state and cannot be changed. That is, the rise and fall of the transmission shaft 33 will not affect the height position relationship of the adjustment knob 32, thereby avoiding errors in the adjustment process due to changes in the height of the adjustment knob 32.

[0050] Furthermore, the lifting and lowering of the transmission shaft 33 drives the grinding assembly at its bottom end to rise and fall synchronously, and the outlet gap in the grinding assembly changes synchronously. When the transmission shaft 33 rises, the grinding gap of the grinding assembly shrinks, and the diameter of the drug powder that can pass through is smaller, and the grinding degree of the equipment is synchronously increased; and when the transmission shaft 33 descends, the outlet gap of the grinding assembly increases synchronously, and the drug powder that can pass through is directly larger, and the grinding degree of the equipment is synchronously reduced, so that the grinding degree of the equipment can be automatically adjusted by rotating the adjustment knob 32 forward and backward, and due to the action of the threaded portion 34, there is a self-locking property between the adjustment knob 32 and the transmission shaft 33, thereby avoiding the change of the grinding degree of the equipment during the grinding process, which leads to a decrease in the grinding quality. Embodiment three:

[0051] Please refer to 6. This embodiment further explains on the basis of the second embodiment:

[0052] The grinding assembly includes a fixed ring 4 fixedly connected to the bottom end of the storage barrel 1, the upper half of the inner contour of the fixed ring 4 is provided with a guide tooth groove 41, the lower half of the inner contour of the fixed ring 4 is provided with a grinding tooth groove 42, a guide head 43 is arranged inside the guide tooth groove 41 and the guide head 43 is fixedly connected to the bottom end of the transmission shaft 33, the bottom end of the guide head 43 is fixedly connected to a grinding head 44, and the bottom end of the grinding head 44 is fixedly connected to a guide plate 45 extending outward.

[0053] The guide head 43 is arranged in the same rotation direction as the guide tooth groove 41 , and the grinding head 44 is arranged in the same rotation direction as the grinding tooth groove 42 .

[0054] The medicine to be ground inside the storage barrel 1 gradually enters the guide tooth groove 41 and contacts the outer surface of the guide head 43 under the squeezing and pushing of the lifting ring 21. At this time, since the guide head 43 is fixedly connected to the transmission shaft 33, the transmission shaft 33 is slidingly connected to the threaded sleeve 2 through the limit portion 35, and the threaded sleeve 2 rotates clockwise under the action of the grinding knob 12, that is, the guide head 43 rotates clockwise synchronously at this time, but the guide tooth groove 41 and the fixing ring 4 are in a fixed state along with the storage barrel 1, that is, at this time, relative rotation occurs between the guide head 43 and the guide tooth groove 41, and similarly, relative rotation also occurs between the grinding head 44 and the grinding tooth groove 42.

[0055] At this time, the medicine located between the guide tooth groove 41 and the guide head 43 is gradually guided along the rotation direction of the guide tooth groove 41 toward the grinding tooth groove 42 under the clockwise rotation of the guide head 43, and in this process, the guide head 43 simultaneously crushes the medicine to refine the medicine particles; then, when the medicine particles reach the grinding tooth groove 42, they are crushed again by the grinding head 44 to complete the grinding of the medicine, and the ground medicine dust falls into the collection component under the guidance of the guide plate 45.

[0056] It should be noted that when the adjusting knob 32 is rotated to cause the transmission shaft 33 to rise and fall, the guide head 43 and the grinding head 44 rise and fall synchronously. At this time, the size of the gap between the grinding head 44 and the guide plate 45 changes synchronously, and the size of the gap between the grinding head 44 and the guide plate 45 directly determines the final grinding degree of the drug. When the gap between the grinding head 44 and the guide plate 45 increases, the passing diameter of the drug powder increases, and the grinding degree of the equipment decreases. When the gap between the grinding head 44 and the guide plate 45 decreases, the passing diameter of the drug powder decreases, and the grinding degree of the equipment increases. Embodiment 4:

[0057] Please refer to 7- Figure 8 This embodiment further illustrates the following on the basis of the third embodiment:

[0058] The vibration mechanism includes a rotating disk 5 fixedly connected to the bottom end of the grinding head 44, a plurality of transmission teeth 51 are fixedly connected to the periphery of the bottom end of the rotating disk 5, and the transmission teeth 51 are distributed in a circular array along the axis of the rotating disk 5, a lifting disk 52 is arranged below the rotating disk 5, a plurality of positioning blocks 53 are fixedly connected around the outer contour of the lifting disk 52, and the positioning blocks 53 are distributed in a circular array along the axis of the transmission teeth 51, a compression spring 54 is fixedly connected to the bottom end of the transmission teeth 51, a retaining ring 55 is fixedly connected to the other end of the compression spring 54, and the retaining ring 55 is engaged with the positioning block 53, a connecting shaft 56 is fixedly connected to the bottom end of the retaining ring 55, and a ratchet gear 57 is fixedly connected to the bottom end of the connecting shaft 56.

[0059] The inclination direction of the transmission tooth 51 is set to be clockwise and the ratio of the length of the positioning block 53 to the height of the transmission tooth 51 is two to one.

[0060] The collecting assembly also includes a collecting barrel 6 for collecting drug dust and a limiting plate 61 for scraping and cleaning the collecting barrel 6. The collecting barrel 6 is located directly below the storage barrel 1 and is penetrated by a ratchet gear 57 through the axis and connected for unidirectional rotation. The limiting plate 61 is slidingly connected to the inner contour of the collecting barrel 6 and is threadedly connected to the connecting shaft 56.

[0061] Furthermore, when the grinding knob 12 drives the grinding head 44 to rotate clockwise, since the rotating disk 5 is fixedly connected to the bottom end of the grinding head 44, and the bottom end of the rotating disk 5 is fixedly connected with the transmission tooth 51, that is, the rotating disk 5 and the transmission tooth 51 rotate synchronously clockwise with the grinding head 44. At this time, the transmission tooth 51 continuously squeezes the positioning block 53 and has a tendency to drive the positioning block 53 and the lifting disk 52 to rotate synchronously. Since the positioning block 53 and the retaining ring 55 are engaged, the retaining ring 55 is fixedly connected to the connecting shaft 56, and the ratchet gear 57 at the bottom end of the connecting shaft 56 is connected to the collecting barrel 6 in a one-way transmission manner, the collecting barrel 6 is in a fixed state, that is, under the fixing action of the collecting barrel 6, the ratchet gear 57, the connecting shaft 56, the retaining ring 55, the positioning block 53 and the lifting disk 52 cannot realize clockwise rotation. At this time, under the inclined direction setting of the transmission tooth 51, the rotation of the transmission tooth 51 will continuously squeeze the positioning block 53 and cause the positioning block 53 and the lifting disk 52 to move downward.

[0062] When the positioning block 53 is squeezed by the transmission tooth 51 and moves downward, the compression spring 54 is compressed synchronously, and when the positioning block 53 and the transmission tooth 51 are out of contact, the compression spring 54 rebounds and drives the lifting plate 52 and the positioning block 53 to reset. At this time, the lifting plate 52 hits the bottom end of the rotating plate 5. Therefore, during the grinding process, the lifting plate 52 and the positioning block 53 are continuously lifted and lowered and hit the rotating plate 5, and then the grinding head 44, the guide head 43 and the grinding head 44 are continuously struck by the rotating plate 5 to cause a small vibration to remove the drug dust attached to the outer surfaces of the grinding head 44, the guide head 43 and the grinding head 44 to reduce the grinding error of the equipment.

[0063] When the equipment is reset, the grinding knob 12 drives the rotating disk 5 and the transmission tooth 51 to rotate counterclockwise. Due to the one-way rotation connection between the collecting barrel 6 and the ratchet gear 57, the transmission tooth 51 further drives the positioning block 53, the lifting disk 52, the retaining ring 55, the connecting shaft 56 and the ratchet gear 57 to rotate clockwise synchronously, and the limit plate 61 continues to be in a fixed state with the collecting barrel 6, that is, there is relative rotation between the limit plate 61 and the connecting shaft 56. Further, the rotation of the connecting shaft 56 causes the collecting barrel 6 to start to rise and fall.

[0064] It should be noted that, in the process of the drug dust passing through the guide plate 45 and being collected on the upper surface of the limit plate 61, some of the drug dust is attached to the inner wall of the collecting cylinder 6. Therefore, when the equipment is reset, the inner wall of the collecting cylinder 6 is scraped by the rising of the collecting cylinder 6 to remove the drug dust attached thereto, thereby further reducing the grinding error of the equipment. At the same time, the limit plate 61 drives the collected drug powder to rise synchronously, which is more conducive to subsequent use by personnel.

[0065] It should be noted that since there is no rigid connection between the rotating disk 5 and the lifting disk 52, the collecting assembly can be freely disassembled to facilitate personnel to take out the ground drug powder. After taking out the drug powder, the connecting shaft 56 can be controlled to rotate clockwise to achieve the resetting process of the collecting assembly.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
