Description

Technical Field

[0001] This utility model relates to the field of drug dispensing equipment technology, and in particular to a biomimetic breaking device for the mouth of an injectable drug bottle. Background Technology

[0002] In the medical field, injectable medications are widely used. The process involves cutting or breaking the vial (such as an ampoule) at the neck to extract the medication. For large-volume extractions, automated dispensing equipment is required. When breaking the already cut vial neck, a breaking device is needed. Manually breaking the vial neck involves using the thumb and forefinger to apply force to the top and bottom of the neck, applying pressure to break it off at the cut or scratch. After breaking, the neck portion can be held and placed into a collection container.

[0003] Compared to the manual breaking process, the existing breaking devices operate more roughly, mostly pushing the bottle opening off by inference, which has a certain impact on the subsequent collection and breaking quality. Existing technologies, such as the ampoule bottle processing assembly disclosed in Chinese invention patent CN105329827A and the hospital ampoule dispensing machine disclosed in Chinese utility model patent CN221797014U, both utilize a single movable lever or L-shaped breaker to push the bottle neck. There is no subsequent processing of the pushed-off bottle neck portion. Firstly, the direction of the fallen bottle neck portion cannot be effectively controlled, allowing it to scatter freely, potentially landing on or being obstructed by equipment components, making collection difficult and increasing the complexity of subsequent processing. Secondly, during the pushing process, there is a probability of adhering or incompletely broken fragments at the broken end of the bottle neck. If the bottle neck is further pushed away from the medicine bottle, these adhering or incompletely broken fragments are more likely to be pushed off and fall into the bottle, contaminating the medicine. This results in poor breakage processing effectiveness.

[0004] Furthermore, existing breaking devices also have limitations in their structural design. They are poorly adaptable to the mouths of injection vials of different sizes and materials, lack a flexible and adjustable structure, and cannot accurately break or clamp the mouths. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a biomimetic breaking device for the mouth of an injectable drug bottle, which solves the problem that the breaking components in the prior art all rely on inference to handle the bottle mouth, resulting in the bottle mouth scattering in all directions after breakage.

[0006] The technical solution of this utility model is as follows: a biomimetic breaking device for the mouth of an injectable drug bottle includes a support component. An opening and closing mechanism is fixedly installed on the support component. The two opening and closing ends of the opening and closing mechanism are respectively provided with a biomimetic gripper I and a biomimetic gripper II. A pressure block is provided on the biomimetic gripper II, and an adjustment mechanism for adjusting the position of the pressure block is provided on the biomimetic gripper II.

[0007] Preferably, the lower end of the bionic gripper I is provided with a replaceable gripper finger pad for insertion; the lower end of the bionic gripper II is provided with a fingertip support block corresponding to the gripper finger pad. The gripper finger pad includes a contact end, one side of which is connected to a connecting part, and the connecting part is provided with an insertion block. The bionic gripper I has an insertion groove for inserting the insertion block; the bionic gripper I also has a concave area that mates with the pressure block. Both the bionic gripper II and the bionic gripper I are L-shaped grippers and are respectively connected to the two opening and closing ends of the opening and closing mechanism by bolts. By inserting the insertion block into the insertion groove on the bionic gripper I, gripper finger pads of different specifications or materials can be quickly replaced to adapt to different bottle opening shapes or specifications. This design not only facilitates equipment maintenance and adjustment but also provides optimized gripping effects for different types of medicine bottles.

[0008] Preferably, the bionic gripper II has a receiving groove, and the adjustment mechanism includes a first lead screw rotatably disposed within the receiving groove, a slider slidably disposed within the receiving groove, the first lead screw engaging with a lead screw nut fixedly disposed on the slider, an adjustment knob fixedly disposed on the first lead screw, and a pressure block fixedly connected to or integrally formed with the slider. As one of the optional adjustment structure forms, it can meet both high-precision adjustment requirements and enable rapid on-site adjustment.

[0009] Preferably, the bionic gripper II has an elongated hole, and a stud is connected to one side of the pressure block. The stud passes through the elongated hole and is locked in place by a nut. As another optional adjustment structure, this design can meet both high-precision adjustment requirements and rapid on-site adjustment.

[0010] Preferably, the clamping block is a rubber clamping block, and the gripper finger pads are rubber blocks. The rubber material has good elasticity, wear resistance, and coefficient of friction, which can provide sufficient friction when clamping the bottle mouth to prevent the bottle mouth from slipping during the breaking process. At the same time, the elasticity of the rubber can buffer the clamping force, protect the bottle mouth from excessive compression and damage, and effectively reduce the generation of fragments.

[0011] Preferably, the opening and closing mechanism includes an electric or pneumatic opening and closing cylinder fixedly mounted on the support assembly. This provides a stable and reliable opening and closing force, ensuring the accurate opening and closing actions of the bionic gripper I and bionic gripper II.

[0012] Preferably, the support assembly includes a motor support, on which a driver is fixedly mounted. The driving end of the driver is connected to a second lead screw. A telescopic guide tube assembly is sleeved on the second lead screw. The lower end of the telescopic guide tube assembly is connected to the motor support, and the upper end is connected to a support platform. The opening and closing mechanism is fixedly mounted on the support platform. A lead screw nut is fixedly mounted on the telescopic guide tube assembly. The lead screw nut is in transmission engagement with the second lead screw. The driver can drive the second lead screw to rotate and move the lead screw nut along the axial direction of the second lead screw. The support assembly not only provides a stable installation foundation for the opening and closing mechanism, but also, through the cooperation of the driver, the second lead screw, and the telescopic guide tube assembly, enables precise telescopic movement of the device in the vertical direction, allowing the entire breaking device to flexibly adapt to different working positions and operational requirements.

[0013] Preferably, the telescopic guide tube assembly includes an inner sleeve fixedly mounted on the motor support, an outer sleeve connected to the support platform, the inner sleeve and the outer sleeve being nested and both being fitted over the second lead screw, the lead screw nut being fixedly mounted on the top of the outer sleeve, the inner sleeve being provided with a guide groove, and the outer sleeve being fixedly provided with a guide post that cooperates with the guide groove.

[0014] The beneficial effects of this invention are as follows: By setting up a support component, a supporting connection foundation can be provided for the entire device. The opening and closing mechanism, in conjunction with bionic grippers I and II, and a pressure block on bionic gripper II, mimics the manual breaking method to clamp the medicine from the bottle neck. After clamping, the broken bottle neck can be further held to prevent it from scattering, facilitating subsequent processing. The bionic breaking method of this device is gentler and more precise, reducing the risk of adhesion at the broken bottle neck or the risk of incompletely broken fragments falling again.

[0015] Furthermore, by setting an adjustment mechanism, the position of the pressure block can be adjusted, which facilitates equipment debugging. At the same time, it also makes it easy to break and clamp medicines of different specifications, thus improving applicability through flexible adjustment. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 , 2 As shown in Embodiment 1, a biomimetic device for breaking the neck of an injectable drug bottle includes a support component 2, which provides a supporting connection base for the entire device. An opening and closing mechanism 3 is fixedly mounted on the support component 2. The two opening and closing ends of the opening and closing mechanism 3 are respectively equipped with biomimetic grippers I 4 and II 5. A pressure block 6 is mounted on the biomimetic gripper II 5, and an adjustment mechanism 7 is provided on the biomimetic gripper II 5 to adjust the position of the pressure block 6 to adapt to bottle necks of different heights and shapes, ensuring that the pressure block 6 can accurately apply pressure to the bottle neck and achieve a stable breaking effect. The opening and closing mechanism 3, in conjunction with the biomimetic grippers I 4 and II 5, and the pressure block 6 mounted on the biomimetic gripper II 5, can mimic the action and force applied by fingers when manually breaking a bottle neck. It accurately simulates the gripping and breaking process of a human hand on the bottle neck, mimicking the manual breaking method to break the drug from the bottle neck. After breaking, the broken bottle neck can be further gripped to prevent the broken pieces from scattering, facilitating subsequent processing. Compared to the inference method in existing technologies, the biomimetic breaking method of this device is gentler and more precise, reducing the risk of adhesion at the bottle mouth or incompletely broken fragments being broken and falling again.

[0020] Specifically, in this embodiment, both the bionic gripper II5 and the bionic gripper I4 are L-shaped grippers, symmetrical and connected to the two opening and closing ends of the opening and closing mechanism 3 by bolts. The opening and closing mechanism 3 includes an electric or pneumatic opening and closing cylinder fixedly mounted on the support assembly 2, which can provide stable and reliable opening and closing force and opening and closing action, ensuring that the opening and closing actions of the bionic gripper I4 and the bionic gripper II5 are accurate, thereby realizing precise clamping and breaking operations on the mouth of the medicine bottle.

[0021] Example 2: A biomimetic breaking device for the mouth of an injectable drug bottle, based on Example 1, such as... Figure 2 As shown, the lower end of the bionic gripper I 4 is provided with a replaceable gripper finger pad 41 that can be inserted. Different sizes of gripper finger pads 41 can be quickly replaced via this insertion method to adapt to different bottle mouth shapes or specifications. The lower end of the bionic gripper II 5 is provided with a fingertip support block 51 corresponding to the gripper finger pad 41. The fingertip support block 51 is connected to the lower end of the bionic gripper II by adhesive, bolts, or insertion. In this embodiment, the pressure block 6 is a rubber pressure block, and the gripper finger pad 41 is a rubber block. The rubber pressure block 6 and gripper finger pad 41 have good elasticity, wear resistance, and coefficient of friction, providing sufficient friction when gripping the bottle mouth to prevent slippage during breakage. Simultaneously, the elasticity of the rubber buffers the clamping force, avoiding rigid contact and protecting the bottle mouth from excessive pressure and damage.

[0022] Specifically in this embodiment, such as Figure 6 As shown, the gripper finger pad 41 includes a contact end 411, with a connecting part 412 connected to one side of the contact end 411. The connecting part 412 is provided with an insertion block 413. The bionic gripper I4 is provided with an insertion groove for inserting the insertion block 413. By inserting the insertion block 413 into the insertion groove on the bionic gripper I4, quick connection and replacement are facilitated. The bionic gripper I4 is provided with a concave area 414 that cooperates with the pressure block 6. The concave area provides space for accommodating and avoiding the bottle opening during the breaking process, resulting in more stable gripping.

[0023] By using interchangeable gripper finger pads of different sizes in conjunction with adjustable pressure blocks, the equipment can be easily maintained and adjusted, and can also provide the best gripping effect for different types of medicine bottles.

[0024] Example 3: A biomimetic breaking device for the mouth of an injectable drug bottle, based on Example 2, such as... Figure 3 As shown, the bionic gripper II5 has a receiving groove 52. The adjustment mechanism 7 includes a first lead screw 53 rotatably disposed in the receiving groove 52. A slider 54 is slidably disposed in the receiving groove 52. The first lead screw 53 is in transmission cooperation with the lead screw nut fixedly disposed on the slider 54. An adjustment knob 55 is fixedly disposed on the first lead screw 53. The pressure block 6 is fixedly connected to the slider 54 or integrally formed.

[0025] In this embodiment, rotating the adjusting knob 55 drives the first lead screw 53 to rotate, and then, under the transmission cooperation of the lead screw nut and the first lead screw, the slider 54 connected to the lead screw nut slides within the receiving groove 52, achieving precise adjustment of the position of the pressure block 6. This adjustment method can meet the requirements of high-precision adjustment and is suitable for breaking bottle mouths of different heights and shapes, improving the versatility and adaptability of the device. For example, when it is necessary to break a medicine bottle with a high mouth, the pressure block 6 can be adjusted upward to a suitable position; conversely, when the bottle mouth is short, the pressure block 6 can be adjusted downward.

[0026] As a further specific implementation, bearing seats are provided at both ends of the receiving groove 52, and the two ends of the first lead screw 53 are respectively connected to the two bearing seats to achieve rotational connection.

[0027] Example 4: A biomimetic breaking device for the mouth of an injectable drug bottle, based on Example 2, such as... Figure 7 As shown, unlike Embodiment 3, the bionic gripper II5 has an elongated hole 56, and a stud 57 is connected to one side of the pressure block 6. The stud 57 passes through the elongated hole 56 and is locked by a nut. In this embodiment, the pressure block is connected to the gripper through the stud and nut. By loosening the nut and moving the stud in the elongated hole, the position of the pressure block can be quickly adjusted. After adjusting it to the correct position, tightening the nut will fix the pressure block.

[0028] Example 5, based on Example 4, such as Figure 4 , 5 As shown, the support assembly 2 includes a motor support, on which a driver 21 is fixedly mounted. The driver 21 can be a drive motor. The drive end of the driver 21 is connected to a second lead screw 22. A telescopic guide tube assembly is sleeved on the second lead screw 22. The lower end of the telescopic guide tube assembly is connected to the motor support, and the upper end is connected to the support platform 23. The opening and closing mechanism 3 is fixedly mounted on the support platform 23. A lead screw nut 24 is fixedly mounted on the telescopic guide tube assembly. The lead screw nut 24 is in transmission cooperation with the second lead screw 22. The driver 21 can drive the second lead screw 22 to rotate and drive the lead screw nut to move axially along the second lead screw 22.

[0029] In this embodiment, this device is part of a conventional automated injectable drug dispensing equipment. It is connected and fixed to the equipment using a motor support. It can be used to replace the existing ampoule bottle breaking device disclosed in Chinese invention patent CN105329827A or the ampoule bottle head breaking component disclosed in Chinese utility model patent CN221797014U, which can achieve high-quality bottle opening operation.

[0030] Specifically, in this embodiment, the telescopic guide tube assembly includes an inner sleeve 25 fixedly mounted on the motor support. One end of the inner sleeve 25 has a flange, which is bolted to the motor support. An outer sleeve 26 is connected to the support platform 23. The inner sleeve 25 and the outer sleeve 26 are nested and both are fitted over the second lead screw 22. The lead screw nut 24 is fixed inside the outer sleeve 26. The inner sleeve 25 has a guide groove 27, and the outer sleeve 26 has a guide post 28 that mates with the guide groove 27.

[0031] When the driver 21 starts, its driving end drives the second lead screw 22 to rotate. The transmission engagement between the second lead screw 22 and the lead screw nut 24 causes the lead screw nut 24 to move axially along the second lead screw 22, driving the outer sleeve to move axially. At the same time, the guide post 28 on the outer sleeve 26 moves along the guide groove 27 of the inner sleeve 25 under the drive of the lead screw nut 24. The cooperation between the guide groove 27 and the guide post 28 plays a guiding role in the movement, ensuring the stability of the movement of the outer sleeve 26, thereby driving the support platform 23 and the opening and closing mechanism 3 installed on it to perform precise actions.

[0032] As a further optional implementation, a branch pipe is provided at the upper end of the inner sleeve, which is located inside the outer sleeve with a gap between them. A bearing seat is provided at the upper end of the branch pipe, which rotates with the second lead screw to support the middle part of the second lead screw 22 and improve the overall rotational stability of the second lead screw.

[0033] Furthermore, in this embodiment, the guide chute 27 is an approximately L-shaped chute. The long section of the L-shaped chute is vertically arranged, and the short section of the L-shaped chute is located at the upper end of the long section and is arranged obliquely. During the breaking operation, the support platform 23 is located in a lower position. The medicine bottle is moved between the bionic gripper I4 and the bionic gripper II5 manually or through the conveying mechanism of existing equipment. At this time, the opening and closing mechanism closes, and the pressing block gradually contacts the mouth of the medicine bottle to break it off and clamp the broken mouth of the medicine bottle. At this point, the inner sleeve 25 and the outer sleeve are in a contracted state relative to each other along their length. Simultaneously, the guide post is located at the lower end of the long groove section of the guide slide 27. As the second lead screw rotates and drives the outer sleeve upward, the guide post moves upward with the outer sleeve. The long groove section of the guide slide 27 limits the movement of the guide post, causing it to move upward axially. At the same time, the support platform moves upward, causing the bottle mouth to separate axially from the bottle, reducing contact between the disconnected bottle mouth and the bottle. When the guide post moves to the upper end of the long groove section of the guide slide 27, it enters the short groove section of the guide slide 27 during its continued upward movement. The outer sleeve rotates under the drive of the second lead screw and moves obliquely upward along the short groove section, causing the support platform to rotate relative to the axis of the outer sleeve, moving the bottle mouth to one side. Furthermore, a collection chamber is set on one side of the equipment. When the bottle mouth moves above the collection chamber, the opening and closing mechanism releases, allowing the bottle mouth to fall into the collection chamber for collection, preventing scattering.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
