Description

Technical Field

[0001] This application relates to the field of medicine bottle clamping and shaking, and in particular to a semi-automatic medicine bottle clamping mechanism. Background Technology

[0002] In the medical field, handling medicine bottles is an important and common task. With the continuous development of medical technology, the requirements for the efficiency and accuracy of medicine bottle storage and mixing are becoming increasingly stringent. Efficient and safe medicine bottle handling methods can improve the overall efficiency of medical work, reduce the workload of medical staff, and also help ensure the quality and safety of medicines, which is of great significance for improving the level of medical services.

[0003] Prior to this technical solution, various methods were conventionally used for holding medicine bottles and mixing medications. For bottle holding, simple manual clamps were commonly used, requiring medical staff to manually adjust the position and force of the clamps to secure the bottle. This method was cumbersome and prone to damaging the bottle due to uneven force. For mixing medications, medical staff typically relied on manually shaking the bottle, which was not only physically demanding but also difficult to guarantee uniformity and consistency due to variations in shaking methods and force among different personnel. Furthermore, some medical institutions used simple mechanical shaking devices, but these devices were often structurally limited and functionally insufficient to simultaneously meet the holding and mixing needs of different types of medicine bottles.

[0004] The shortcomings of existing technologies are that manual clamps are inconvenient to operate and easily damage medicine bottles, manual shaking of the liquid cannot guarantee consistent mixing, and simple mechanical shaking devices cannot meet the processing needs of various medicine bottles. These problems lead to low efficiency in medicine bottle processing and may affect the quality and efficacy of the medicines. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a semi-automatic medicine bottle clamping mechanism.

[0006] To achieve the above objectives, the following technical solution is proposed: A semi-automatic medicine bottle clamping mechanism includes a frame. A vial clamping seat is connected to the bottom of the frame via a shaking device. An ampoule holder is provided at the top of the frame. The vial clamping seat has a fixed vial holder. The ampoule holder includes an ampoule clamping seat with several vial slots fixed to the frame. A first clamping plate and a second clamping plate are slidably connected to the left and right sides of the ampoule clamping seat via sliding rods. The first and second clamping plates are equipped with a first semi-automatic clamping mechanism. For holding ampoules, the vial holder uses a second semi-automatic clamping mechanism to hold the vials. The shaking device includes a main shaft rotatably connected to the bottom of the frame. A drive gear is fixed at one end of the main shaft located below the frame, and a driven main gear is fixed at the other end of the main shaft located above the frame. A driven secondary gear meshing with the driven main gear is rotatably connected to the bottom of the frame. An eccentric connecting column offset from its axis is provided at the upper end of the driven secondary gear. A bearing fixed to the vial holder is sleeved on the eccentric connecting column.

[0007] The working principle of the shaking device in this application is as follows: The drive gear is connected to an external drive assembly, which provides power. When the drive gear rotates, it drives the driven main gear to rotate coaxially, thereby driving the driven secondary gear to rotate. Due to the eccentric setting of the eccentric connecting column and the driven secondary gear, the vial holder and the frame make relative shaking motion, thereby causing the vial holder fixed to make shaking motion. The vial usually stores powdered medicine. After the liquid medicine from the ampoule is manually injected into the vial, it needs to be shaken to mix. The vial holder holds the vial and shakes it to achieve mixing of the liquid medicine in the vial. In addition, multiple sets of driven secondary gears can be set to increase the stability of the shaking motion.

[0008] Preferably, the first semi-automatic clamping mechanism includes a slide rail disposed at the bottom of the ampoule clamping base. The first clamping plate and the second clamping plate are symmetrically arranged on the slide rail. A first slider and a second slider are slidably connected on the slide rail. A first bolt is fixed below the first slider, and a second bolt is fixed below the second slider. A first connecting rod and a third connecting rod are respectively hinged to the bottom ends of the first clamping plate. A second connecting rod and a fourth connecting rod are respectively hinged to the bottom ends of the second clamping plate. The first connecting rod and the second connecting rod are simultaneously hinged to the first bolt, and the third connecting rod and the fourth connecting rod are simultaneously hinged to the second bolt. A clamping spring is connected between the first bolt and the second bolt.

[0009] The working principle of the first semi-automatic clamping mechanism of this application is as follows: In the initial state, the clamping spring is in a contracted state, and the first slider and the second slider are closest to each other. Under the action of the first link, the second link, the third link and the fourth link, the first clamping plate and the second clamping plate are in the clamping position. When the ampoule is manually placed between the first clamping plate and the second clamping plate from top to bottom, the first clamping plate and the second clamping plate move away from each other. Under the action of the first link, the second link, the third link and the fourth link, the first slider and the second slider move away from each other. Until the ampoule is placed in the medicine bottle slot, the hand leaves the ampoule. Under the contraction force of the clamping spring, the first slider and the second slider tend to move closer and further apart, thus achieving the clamping of the ampoule. This application only requires placing the ampoule between the first clamping plate and the second clamping plate to achieve semi-automatic clamping.

[0010] Preferably, a slide rod spring is fixed on the slide rod, and flexible card interfaces are provided on the first clamp plate and the second clamp plate, which are arranged symmetrically on the left and right sides and are V-shaped.

[0011] Since ampoules are mostly made of fragile materials such as glass, the purpose of this application in setting up a sliding rod spring and a flexible locking interface is to change the rigid frictional contact to a flexible contact, so as to ensure that the ampoule is not easily broken when clamped and improve operational safety.

[0012] Preferably, the second semi-automatic clamping mechanism includes a clamping base plate and clamping claws fixed on a vial clamping seat. The clamping base plate is slidably connected to an I-shaped limiting block. The I-shaped limiting block includes upper and lower parallel limiting plates and a connecting block connecting the upper and lower limiting plates. Limiting bolts are connected to both ends of the upper and lower limiting plates. The connecting block is connected to the clamping base plate through a limiting spring. The clamping claws include clamping components arranged symmetrically on the left and right sides. Each clamping component has an integrally formed arc-shaped chuck and a sliding connecting block. The sliding connecting block has a sliding groove. The sliding grooves of the left and right clamping components are at a certain angle and symmetrically arranged. The limiting bolts are locked in the sliding grooves. The sliding connecting block is slidably connected between the upper and lower limiting plates.

[0013] The working principle of the second semi-automatic clamping mechanism of this application is as follows: The sliding grooves of the left and right clamping components are arranged at a certain angle and symmetrically, and are distributed in a figure-eight shape from the inside to the outside of the clamping base plate. In the initial state, the limiting spring is in a relaxed state, pushing the I-shaped limiting block outward to the front end of the figure-eight distributed sliding groove. When the manual inserts the vial from the outside of the arc-shaped clamp into the inside of the arc-shaped clamp, the left and right arc-shaped clamps move away from each other. Since the limiting bolt of the I-shaped limiting block is stuck in the sliding groove, the I-shaped limiting block is forced to move closer to the inside of the clamping base plate, thereby squeezing the limiting spring. When the vial is stuck inside the arc-shaped clamp, the manual releases the vial. At this time, the limiting spring relaxes, causing the I-shaped limiting block to tend to move away from the inside of the clamping base plate, causing the left and right arc-shaped clamps to tend to move closer to each other, thus achieving clamping of the vial. This application only requires placing the vial between the left and right curved clamps to achieve semi-automatic clamping.

[0014] Preferably, the front end of the arc-shaped chuck has a circular arc surface.

[0015] The purpose of providing an arc surface at the front end of the arc-shaped chuck in this application is to allow the vial to smoothly transition to the inside of the arc-shaped chuck, thereby reducing placement resistance and improving work efficiency.

[0016] Preferably, the bottom of the vial holder is connected to a reset link, the reset link passes through the clearance groove of the frame, and one end of the reset link passing through the clearance groove of the frame is connected to the frame through a reset spring of the holder.

[0017] The purpose of this application in setting the reset linkage and the clamping seat reset spring is to reset the vial clamping seat when the external drive component disconnects the power, so that the operator can put in and take out vials from the same position.

[0018] The beneficial effects of this utility model are: after the medicine liquid in the ampoule is manually injected into the vial, it is necessary to shake it to mix it. The vial holder is used to hold the vial and shake it to mix the medicine liquid in the vial. Attached Figure Description

[0025] Example

[0026] This embodiment proposes a semi-automatic medicine bottle clamping mechanism, referencing... Figure 1 The device includes a frame 1, with a vial holder 3 connected to the bottom of the frame 1 via a shaking device 2. An ampoule holder 4 is located at the top of the frame 1. A vial holder 5 is fixed to the vial holder 3. The ampoule holder 4 includes an ampoule holder 41 fixed to the frame 1 and having several vial slots 11. (See reference...) Figure 5 The ampoule holder 41 has a first clamping plate 42 and a second clamping plate 43 slidably connected to its left and right sides via slide rods 44, respectively. The first clamping plate 42 and the second clamping plate 43 are equipped with a first semi-automatic clamping mechanism for clamping the ampoule 8. The vial holder 5 uses a second semi-automatic clamping mechanism to clamp the vial 7. The shaking device 2 includes a main shaft rotatably connected to the bottom of the frame 1. (Reference) Figure 3 The main shaft is fixed with a drive gear 21 at one end below the frame 1 and a driven main gear 22 at the other end above the frame 1. A driven secondary gear 23 that meshes with the driven main gear 22 is rotatably connected to the bottom of the frame 1. An eccentric connecting column 24 that is offset from its axis is provided at the upper end of the driven secondary gear 23. A bearing 25 fixed to the vial holder 3 is sleeved on the eccentric connecting column 24.

[0027] The working principle of the shaking device 2 in this application is as follows: The drive gear 21 is connected to an external drive assembly, which provides power. When the drive gear 21 rotates, it drives the driven main gear 11 to rotate coaxially, thereby driving the driven secondary gear 23 to rotate. Due to the eccentric setting of the eccentric connecting column 24 and the driven secondary gear 23, the vial holder 3 and the frame 1 are driven to make relative shaking motion, thereby driving the vial holder 5 fixed to make shaking motion. The vial usually stores powdered medicine. After the medicine liquid in the ampoule is manually injected into the vial, it needs to be shaken to mix. The vial holder 5 holds the vial and shakes it to achieve mixing of the medicine liquid in the vial. In addition, multiple sets of driven secondary gears 23 can be set to increase the stability of the shaking motion. The bottom of the frame is connected to the vial holder via a shaking device, and the top of the frame is equipped with an ampoule holder. The vial holder is fixed on the vial holder. This structure allows the mechanism to simultaneously hold ampoules and vials and mix the medicine, improving the efficiency and accuracy of vial processing.

[0028] For details, please refer to Figure 4 The first semi-automatic clamping mechanism includes a slide rail 47 disposed at the bottom of the ampoule clamping base 41. The first clamping plate 42 and the second clamping plate 43 are symmetrically arranged on the slide rail 47. A first slider 48 and a second slider 49 are slidably connected on the slide rail 47. A first bolt 410 is fixed below the first slider 48, and a second bolt 411 is fixed below the second slider 49. A first connecting rod 412 and a third connecting rod 414 are respectively hinged to the bottom ends of the first clamping plate 42. A second connecting rod 413 and a fourth connecting rod 415 are respectively hinged to the bottom ends of the second clamping plate 43. The first connecting rod 412 and the second connecting rod 413 are simultaneously hinged to the first bolt 410, and the third connecting rod 414 and the fourth connecting rod 415 are simultaneously hinged to the second bolt 411. A clamping spring 416 is connected between the first bolt 410 and the second bolt 411.

[0029] The working principle of the first semi-automatic clamping mechanism of this application is as follows: In the initial state, the clamping spring 416 is in a contracted state, and the first slider 48 and the second slider 49 are closest to each other. Under the action of the first connecting rod 412, the second connecting rod 413, the third connecting rod 414 and the fourth connecting rod 415, the first clamping plate 42 and the second clamping plate 43 are in the clamping position. When the ampoule is manually placed between the first clamping plate 42 and the second clamping plate 43 from top to bottom, the first clamping plate 42 and the second clamping plate 43 move away from each other. Under the action of the first link 412, the second link 413, the third link 414 and the fourth link 415, the first slider 48 and the second slider 49 move relatively away from each other until the ampoule is placed in the medicine bottle slot 11. When the hand leaves the ampoule, under the contraction force of the clamping spring 416, the first slider 48 and the second slider 49 tend to move relatively closer and further apart, thus achieving the clamping of the ampoule. This application only requires placing the ampoule between the first clamping plate 42 and the second clamping plate 43 to achieve semi-automatic clamping.

[0030] Specifically, a slide rod spring 45 is fixed on the slide rod 44, and flexible card interfaces 46 are provided on the first clamping plate 42 and the second clamping plate 43, which are symmetrically arranged on the left and right sides. The flexible card interfaces 46 are V-shaped.

[0031] Since ampoules are mostly made of fragile materials such as glass, the purpose of this application in setting up the slide spring 45 and the flexible clamping interface 46 is to change the rigid frictional contact to a flexible contact, so as to ensure that the ampoule is not easily broken when clamped and improve the operational safety.

[0032] For details, please refer to Figure 2 The second semi-automatic clamping mechanism includes a clamping base plate 51 and a jaw 55 fixed on a vial clamping seat 3. The clamping base plate 51 is slidably connected to an I-shaped limiting block 52. The I-shaped limiting block 52 includes upper and lower parallel limiting plates and a connecting block connecting the upper and lower limiting plates. Limiting bolts 54 are connected to both ends of the upper and lower limiting plates. The connecting block is connected to the clamping base plate 51 through a limiting spring 53. The jaw 55 includes clamping components arranged symmetrically on the left and right. The clamping components are provided with an integrally formed arc-shaped chuck 551 and a sliding connecting block 552. The sliding connecting block 552 is provided with a sliding groove 553. The sliding grooves 553 of the left and right clamping components are at a certain angle and symmetrically arranged. The limiting bolts 54 are locked in the sliding grooves 553. The sliding connecting block 552 is slidably connected between the upper and lower limiting plates.

[0033] The working principle of the second semi-automatic clamping mechanism of this application is as follows: The sliding grooves 553 of the left and right clamping components are arranged at a certain angle and symmetrically, and are distributed in a figure-eight shape from the inside to the outside of the clamping base plate 51. In the initial state, the limiting spring 53 is in a relaxed state, pushing the I-shaped limiting block 52 outward from the outside of the clamping base plate 51 to the front end of the figure-eight distributed sliding groove 553. When the vial is manually inserted from the outside of the arc-shaped clamp 551 into the inside of the arc-shaped clamp 551, the left and right arc-shaped clamps 551 move away from each other. During operation, the limiting bolt 54 of the I-shaped limiting block 52 is engaged within the sliding groove 553, causing the I-shaped limiting block 52 to move closer to the inside of the clamping base plate 51, thereby compressing the limiting spring 53. When the vial is secured inside the arc-shaped clamp 551, the user releases the vial, at which point the limiting spring 53 relaxes, causing the I-shaped limiting block 52 to tend to move away from the inside of the clamping base plate 51. This causes the left and right arc-shaped clamps 551 to tend to move closer together, thus clamping the vial. This application only requires placing the vial between the left and right arc-shaped clamps 551 to achieve semi-automatic clamping.

[0034] Specifically, the front end of the arc-shaped chuck 551 is provided with an arc surface. The purpose of providing an arc surface at the front end of the arc-shaped chuck 551 in this application is to allow the vial to smoothly transition to the inner side of the arc-shaped chuck 551, thereby reducing placement resistance and improving work efficiency.

[0035] Specifically, the bottom of the vial holder 3 is connected to a reset link 31, which passes through the clearance groove 12 of the frame 1. One end of the reset link 31 passing through the clearance groove 12 of the frame 1 is connected to the frame 1 through the holder reset spring 32.

[0036] The purpose of this application in setting the reset link 31 and the clamping seat reset spring 32 is to reset the vial clamping seat 3 when the external drive component disconnects the power, so that the operator can put in and take out vials from the same position.
