Description

Technical Field

[0001] This invention relates to the field of breaking the neck of an ampoule, specifically to an ampoule breaker. Background Technology

[0002] Ampoules are used to hold medications. Because they are made of glass, they are relatively hard, and breaking them directly at the neck is not easy. Currently, a grinding wheel is often used to score the neck of the ampoule before breaking it. To make it easier, hospitals have developed an integrated design with a grinding wheel on the handle and multiple circular slots of different diameters for breaking the ampoule. This is more convenient than the traditional design, but it still has some drawbacks. First, it requires two steps: first, scoring with the grinding wheel, then changing the position to fit the slot onto the ampoule and break it. The diameter of the ampoule must also be considered when selecting a slot of the appropriate diameter. If the hole is too large, the gap is too big, making it difficult to break; if the gap is too small, it is difficult to lock in place. This is very inconvenient, especially in emergency situations. Therefore, how to break ampoules more easily is a problem that technicians in this field urgently need to solve. Summary of the Invention

[0003] The purpose of this invention is to provide an ampoule breaker to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an ampoule breaker, comprising a vertical left handle and a right handle located to the right of the left handle. The lower end of the left handle is bent horizontally inward and fitted with a downward-facing left clamping plate, and the lower end of the left clamping plate is bent horizontally outward to form a horizontal section. The lower end of the right handle is bent inward and connected to a downward-facing right clamping plate, which is arc-shaped parallel to the axis of the ampoule to prevent slippage. The end of the horizontal section is bent downward to form a mounting section, the lower end of which does not extend downward beyond the lower end of the right clamping plate to avoid contact with the lower side of the ampoule neck. The left and right handles are connected by an elastic telescopic mechanism. The telescopic mechanism serves as a guide and elastic return mechanism.

[0005] It also includes two circular grinding wheels, one above the other, located inside the mounting section. A flexible clearance mechanism is provided between the grinding wheels and the mounting section. The clearance mechanism allows the two grinding wheels to slide to both sides on the ampoule to form scratches that facilitate breakage. The clearance mechanism is flexible, ensuring that the pressure can produce scratches, while the force is not too great to avoid crushing the ampoule. A storage gap is provided between the grinding wheels and the mounting section. The grinding wheels are circular, and the end near the mounting section can be flat, thus providing more storage space. At the same time, when the grinding wheels squeeze the ampoule, they will slide to both sides.

[0006] Preferably, the avoidance mechanism includes a connecting rod connected to the left end of the grinding wheel, and the connecting rod is rotatably connected to the mounting part by a pin. The connecting rod is equipped with a mounting hole for mounting the pin, and an elastic return component is provided between the connecting rod and the mounting part. The upper and lower connecting rods are arranged in an intersecting "X" shape. The intersecting "X" shape facilitates sliding to both sides to form an arc.

[0007] Preferably, the return component is an elastic rubber sleeve, which is fitted onto the pin, with one end of the rubber sleeve fixedly connected to the pin and the other end fixedly connected to the connecting rod. Alternatively, a torsion spring can be used; compared to a torsion spring, the rubber sleeve is smaller and more convenient.

[0008] Preferably, the left clamp is an arc shape parallel to the axis of the ampoule, making it easy to wrap around the ampoule and preventing slippage.

[0009] Preferably, the grinding wheel has a cutting edge arranged circumferentially, and the cutting edges of the two grinding wheels are close to each other. The closer the two scratches are, the easier it is to break them off.

[0010] Preferably, the two grinding wheels are fitted together, one on top of the other. This allows the scratches to connect, forming a single, continuous line that is easy to break off.

[0011] Preferably, the telescopic mechanism includes a square-section guide block fixed to the inner wall of the right handle and a guide sleeve fitted onto the guide block. The other end of the guide sleeve is fixed to the inner wall of the left handle, and the guide block and the guide sleeve are connected by a spring. The guide block and the guide sleeve provide guidance and cooperate with each other, while the spring provides a return function.

[0012] Preferably, the device also includes a rotating mechanism disposed between the left clamp and the mounting portion to ensure that the left clamp adheres to the ampoule. The ampoule is tapered at the top and thicker at the bottom, and is tilted when viewed from one side. Therefore, to better adhere to the ampoule, the left clamp is rotated, resulting in a larger contact area and better fixation. The rotating mechanism, disposed between the mounting portion and the left clamp, primarily accommodates the forces acting on both the grinding wheel and the left clamp.

[0013] Preferably, the rotating mechanism includes an "L"-shaped connecting plate connected to the lower end of the left handle, and the lower end of the connecting plate is flipped and connected to the horizontal part. The connecting plate drives the horizontal part to compress.

[0014] Preferably, the lower end of the connecting plate is connected to the horizontal part by a rubber strip. The rubber strip can bend and deform when the connecting plate is stressed, so that the grinding wheel and the left clamp plate abut against the ampoule. A rubber strip with a certain toughness and strength is used here. A hinged connection combined with a torsion spring can also be used. However, this rubber strip connection has a more compact structure. At the same time, the cross-section of the rubber strip can be trapezoidal, with the smaller diameter end connected to the connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When using, simply place the right and left clamps onto the ampoule, align the grinding wheel with the neck of the ampoule, squeeze the left and right handles, and bring the left and right clamps closer together. The grinding wheel will press against the neck of the ampoule, and at the same time, the cross-shaped "X"-shaped connecting rod will cause the two grinding wheels to slide to both sides. Under the elastic force of the rubber sleeve, they will elastically press against the neck of the ampoule, thus creating scratches. Then, pry it to the right handle to break the ampoule. This method is different from the traditional method, which can be done in one step by simply clamping and flipping without changing the position. It is simple and convenient, and it is applicable regardless of the diameter of the ampoule.

[0017] 2. Place the two grinding wheels together with their cutting edges close together to ensure that the skid marks can be connected into a single piece, making it easy to break off;

[0018] 3. The connecting plate design allows the left clamp to fit better against the ampoule, resulting in a better breakage effect. Attached Figure Description

[0028] Example 1

[0029] Please see Figures 1 to 5 This invention provides a technical solution for an ampoule breaker: an ampoule breaker includes a vertical left handle 1 and a right handle 2 located to the right of the left handle 1. The lower end of the left handle 1 is bent inward horizontally and fitted with a downward-facing left clamp 11, and the lower end of the left clamp 11 is bent outward horizontally to form a horizontal portion 12. The lower end of the right handle 2 is bent inward and connected to a downward-facing right clamp 21, which is arc-shaped parallel to the axis of the ampoule to prevent slippage. The end of the horizontal portion 12 is bent downward to form a mounting portion 13, the lower end of which does not extend downward beyond the lower end of the right clamp 21 to avoid contact with the lower side of the ampoule neck. The left handle 1 and the right handle 2 are connected by an elastic telescopic mechanism. The telescopic mechanism serves as a guide and elastic return mechanism. The telescopic mechanism includes a square-section guide block 4 fixed to the inner wall of the right handle 2 and a guide sleeve 41 sleeved on the guide block 4. The other end of the guide sleeve 41 is fixed to the inner wall of the left handle 1, and the guide block 4 and the guide sleeve 41 are connected by a spring 42. The guide block 4 and the guide sleeve 41 play a guiding role and cooperate with each other, while the spring 42 plays a returning role.

[0030] It also includes two circular grinding wheels 3, one above the other, located inside the mounting part 13. A flexible clearance mechanism is provided between the grinding wheels 3 and the mounting part 13. This mechanism allows the two grinding wheels 3 to slide to both sides on the ampoule to create scratches that facilitate breakage. The clearance mechanism is flexible, ensuring pressure is applied to create scratches without excessive force that could crush the ampoule. A storage gap is provided between the grinding wheels 3 and the mounting part 13. The grinding wheels 3 are circular, with one end near the mounting part 13 being flat, providing more storage space. Furthermore, when the grinding wheels 3 press against the ampoule, they slide to the sides. The grinding wheels 3 have blades on their circumference, and the blades of the two grinding wheels 3 are close to each other. This closer proximity of the scratches makes breakage easier. The two grinding wheels 3 are fitted together vertically, allowing the scratches to connect and form a single, continuous scratch, facilitating breakage.

[0031] The avoidance mechanism includes a connecting rod 31 connected to the left end of the grinding wheel 3, and the connecting rod 31 is rotatably connected to the mounting part 13 via a pin. The connecting rod 31 has a mounting hole for the pin.

The "X" shape facilitates sliding to both sides, forming an arc. The return component is a flexible rubber sleeve 32, which is fitted onto the pin, with one end of the rubber sleeve 32 fixedly connected to the pin and the other end fixedly connected to the connecting rod 31. A torsion spring can also be used; compared to a torsion spring, the rubber sleeve 32 is smaller and more convenient. The left clamping plate 11 is an arc shape parallel to the axis of the ampoule, facilitating its wrapping. It is not prone to slippage.

[0032] Example 2

[0033] Please see Figures 6 to 7 This invention provides a technical solution for an ampoule breaker: an ampoule breaker includes a vertical left handle 1 and a right handle 2 located to the right of the left handle 1. The lower end of the left handle 1 is bent inward horizontally and fitted with a downward-facing left clamp 11, and the lower end of the left clamp 11 is bent outward horizontally to form a horizontal portion 12. The lower end of the right handle 2 is bent inward and connected to a downward-facing right clamp 21, which is arc-shaped parallel to the axis of the ampoule to prevent slippage. The end of the horizontal portion 12 is bent downward to form a mounting portion 13, the lower end of which does not extend downward beyond the lower end of the right clamp 21 to avoid contact with the lower side of the ampoule neck. The left handle 1 and the right handle 2 are connected by an elastic telescopic mechanism. The telescopic mechanism serves as a guide and elastic return mechanism. The telescopic mechanism includes a square-section guide block 4 fixed to the inner wall of the right handle 2 and a guide sleeve 41 sleeved on the guide block 4. The other end of the guide sleeve 41 is fixed to the inner wall of the left handle 1, and the guide block 4 and the guide sleeve 41 are connected by a spring 42. The guide block 4 and the guide sleeve 41 play a guiding role and cooperate with each other, while the spring 42 plays a returning role.

[0034] It also includes two circular grinding wheels 3, one above the other, located inside the mounting part 13. A flexible clearance mechanism is provided between the grinding wheels 3 and the mounting part 13. This mechanism allows the two grinding wheels 3 to slide to both sides on the ampoule to create scratches that facilitate breakage. The clearance mechanism is flexible, ensuring pressure is applied to create scratches without excessive force that could crush the ampoule. A storage gap is provided between the grinding wheels 3 and the mounting part 13. The grinding wheels 3 are circular, with one end near the mounting part 13 being flat, providing more storage space. Furthermore, when the grinding wheels 3 press against the ampoule, they slide to the sides. The grinding wheels 3 have blades on their circumference, and the blades of the two grinding wheels 3 are close to each other. This closer proximity of the scratches makes breakage easier. The two grinding wheels 3 are fitted together vertically, allowing the scratches to connect and form a single, continuous scratch, facilitating breakage.

[0035] The avoidance mechanism includes a connecting rod 31 connected to the left end of the grinding wheel 3, and the connecting rod 31 is rotatably connected to the mounting part 13 via a pin. The connecting rod 31 has a mounting hole for the pin. A flexible return component is provided between the connecting rod 31 and the mounting part 13, and the upper and lower connecting rods 31 are arranged in an intersecting "X" shape. The "X" shape facilitates sliding to both sides, forming an arc. The return component is a flexible rubber sleeve 32, which is fitted onto the pin, with one end of the rubber sleeve 32 fixedly connected to the pin and the other end fixedly connected to the connecting rod 31. A torsion spring can also be used; compared to a torsion spring, the rubber sleeve 32 is smaller and more convenient. The left clamping plate 11 is an arc shape parallel to the axis of the ampoule, facilitating its wrapping. It is not prone to slippage.

[0036] It also includes a rotating mechanism disposed between the left clamp 11 and the mounting part 13 to cause the left clamp 11 to adhere to the ampoule. The ampoule is tapered at the top and thicker at the bottom, and is tilted when viewed from one side. Therefore, in order to better adhere to the ampoule, the left clamp 11 is flipped, resulting in a large contact area and good fixation. The rotating mechanism is disposed between the mounting part 13 and the left clamp 11, mainly to balance the force on the grinding wheel 3 and the left clamp 11. The rotating mechanism includes an "L"-shaped connecting plate 5 connected to the lower end of the left handle 1, and the lower end of the connecting plate 5 is flipped and connected to the horizontal part 12. The horizontal part 12 is pressed by the connecting plate 5. The lower end of the connecting plate 5 is connected to the horizontal part 12 by a rubber strip 51. The rubber strip 51 can be bent and deformed when the connecting plate 5 applies force so that the grinding wheel 3 and the left clamp 11 press against the ampoule. Here, a rubber strip 51 with a certain toughness and strength is used. It can also be connected by a hinge and combined with a torsion spring. However, this rubber strip 51 connection has a more compact structure. At the same time, the cross-section of the rubber strip 51 can be trapezoidal, with the small diameter end connected to the connecting plate 5.

[0037] Working principle: In use, simply place the right clamp 21 and left clamp 11 onto the ampoule, align the grinding wheel 3 with the neck of the ampoule, and squeeze the left handle 1 and right handle 2. The left clamp 11 and right clamp 21 will move closer together, and the grinding wheel 3 will press against the neck of the ampoule. At the same time, the cross-shaped "X"-shaped connecting rod 31 will cause the two grinding wheels 3 to slide to both sides, and under the elastic force of the rubber sleeve 32, they will elastically press against the neck of the ampoule, thus creating scratches. Then, bend the ampoule towards the right handle 2 to break it. Compared to the traditional method, this method can be completed in one step by simply clamping and flipping it without changing positions. It is simple and convenient, and it is applicable regardless of the diameter of the ampoule. The two grinding wheels 3 are pressed together with their blades close together, ensuring that the scratches are connected as a whole, making it easy to break. The connecting lever 5 allows the left clamp 11 to fit better against the ampoule, resulting in a better breaking effect.
