Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ampoule bottle breaking device. Background Technology

[0002] Ampoules, as a common type of sealed, small-capacity liquid medication packaging container, are widely used in medical, pharmaceutical, and laboratory fields due to their excellent sealing and light-proof properties. Ampoules are typically made of glass, with a pre-fired ring-shaped groove between the body and neck. This groove allows for easy and neat breaking of the neck to expose the mouth for dispensing the medication. Users usually use their fingers, or with the aid of gauze or cotton balls, to hold the ampoule body and neck and bend it in opposite directions. Some users may use a grinding wheel to pre-scrape the groove to weaken the force, or use simple metal pieces or plastic clips as auxiliary tools. However, the existing technology has the following problems:

[0003] Because the glass surface is extremely sharp when breaking the bottle by hand, the operator is very likely to cut their fingers if they are not careful or apply uneven force. The risk is even higher during emergency or continuous operation. Flying glass shards may also injure the eyes or skin. Furthermore, the fingers may come into direct contact with the broken part of the bottle, increasing the risk of microbial or foreign object contamination of the liquid. When using methods such as pre-scraping with a grinding wheel or using plastic slots, it is difficult to control the scratching force of the grinding wheel evenly, which may result in uneven scratches. The simple slot structure is simple and cannot be accurately adapted to different sizes of ampoules, resulting in inconsistent breaking results and the possibility of producing shards or irregular breaks. Utility Model Content

[0004] This invention provides an ampoule breaking device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An ampoule-breaking device includes four bottle-body positioning cylinders. Each of the four positioning cylinders has a breaking mechanism at its top. A connecting plate is fixedly connected between the opposing surfaces of two adjacent positioning cylinders. Two sliding rods are fixedly installed between the front and rear sides of the inner wall of each positioning cylinder. Two sliding plates are slidably installed on the outer walls of each sliding rod. An arc-shaped clamping plate is fixedly installed between the opposing surfaces of the two sliding plates. Rubber pads are fixedly adhered to the opposing surfaces of the two arc-shaped clamping plates. A return spring is fixedly installed between the opposing surfaces of the two sliding plates on the outer walls of each sliding rod. The return spring is sleeved on the outer wall of the sliding rod. A first pressure rod is fixedly installed on the opposing back surfaces of the two arc-shaped clamping plates. The other ends of the two first pressure rods pass through the front and rear sides of the positioning cylinder and are fixedly installed with first pressure plates.

[0007] A further improvement of this utility model is that: the bottle-breaking mechanism includes a protective cap, the inner cavity of the protective cap is vertically connected to the inner cavity of the bottle positioning cylinder, the outer wall of the protective cap is rotatably connected to a movable ring, springs are fixedly installed on both the left and right sides of the inner wall of the protective cap, pressure plates are fixedly installed on the opposite ends of the two springs, grinding wheels are fixedly installed on the opposite surfaces of the two pressure plates, and arc-shaped grooves with vertical penetration are opened on the opposite surfaces of the two grinding wheels.

[0008] A further improvement of this utility model is that: a second pressure rod is fixedly installed on the opposite sides of the two pressure plates, the second pressure rod is located inside the spring, and the other ends of the two second pressure rods respectively penetrate to the left and right sides of the protective cover and are fixedly installed with a second pressure plate, the second pressure plate being located below the movable ring.

[0009] A further improvement of this utility model is that the top of the protective cover has a discharge hole that penetrates its inner cavity.

[0010] A further improvement of this utility model is that: an extension plate is fixedly installed on the bottom rear side of the movable ring, a T-shaped hinge plate is hinged to the bottom of the extension plate, a fixing box is fixedly installed above the rear end of the bottle positioning cylinder, the fixing box is located above the first pressure plate, the fixing box has a sliding chamber, and the horizontal part of the T-shaped hinge plate is slidably connected to the sliding chamber.

[0011] A further improvement of this utility model is that the gap between the arc-shaped grooves of the two grinding wheels and the gap between the opposite surfaces of the two arc-shaped clamping plates are on the same vertical line.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides an ampoule bottle breaking device. Through the closed design of the protective cap and built-in grinding wheel, the hands do not come into contact with the glass cross-section during operation. After the cap is broken, it is discharged directly through the discharge hole, which completely eliminates the risk of glass shards flying and cuts caused by breaking the bottle by hand. At the same time, the rubber pad of the arc clamping plate prevents the fingers from contacting the bottle body when fixing the bottle body. Moreover, there is no need to touch the broken surface of the bottle neck during the entire operation, which significantly reduces the possibility of microorganisms or foreign objects contaminating the medicine.

[0014] 2. This utility model provides an ampoule bottle breaking device. The bottle positioning cylinder is equipped with a return spring and a sliding plate. By pressing the first pressure plate, the arc clamping plate is driven to adapt to bottles of different diameters. The grinding wheel of the bottle breaking mechanism is pre-tightened by the spring. Pressing the second pressure plate can automatically fit the bottle neck, ensuring uniform scratch force and avoiding uneven cross-section caused by different depths. With the design of four parallel bottle positioning cylinders, it can achieve efficient and stable adaptation to multiple bottle sizes, improving compatibility and bottle breaking efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2As shown, this utility model provides an ampoule-breaking device, including four bottle-body positioning cylinders 1. Each of the four bottle-body positioning cylinders 1 has a breaking mechanism 2 at its top. A connecting plate 3 is fixedly connected between the opposite faces of two adjacent bottle-body positioning cylinders 1. The four bottle-body positioning cylinders 1 connected in parallel by the connecting plates 3 can hold ampoules of different sizes and break them one by one, improving breaking efficiency. Two sliding rods 11 are fixedly installed between the front and rear sides of the inner wall of each bottle-body positioning cylinder 1. Two sliding plates 12 are slidably installed on the outer walls of the two sliding rods 11. An arc-shaped clamping plate 122 is fixedly installed between the opposite faces of the two left and right sliding plates 12. A rubber pad 123 is fixedly adhered to the opposite faces of the two arc-shaped clamping plates 122. A return spring 121 is fixedly installed between the opposite faces of the two sliding plates 12 on the outer wall of the two sliding rods 11. The return spring 121 is sleeved on the outer wall of the sliding rod 11. A first pressure rod 13 is fixedly installed on the opposite back faces of the two arc-shaped clamping plates 122. The other ends of the two first pressure rods 13 pass through the front and rear sides of the bottle positioning cylinder 1 and are fixedly installed with a first pressure plate 14.

[0023] By pressing the first pressure plate 14 simultaneously with the index finger and thumb, the two arc-shaped clamping plates 122 move closer together with the help of the first pressure rod 13. During the movement, the sliding connection between the sliding plates 12 on both sides of the arc-shaped clamping plates 122 and the sliding rod 11 maintains stability. At the same time, the rubber pad 123 clamps the bottle body to prevent scratches and improve clamping stability. Meanwhile, the two sliding plates 12 on the outer wall of the sliding rod 11 also compress the return spring 121. Once the first pressure plate 14 is released, the arc-shaped clamping plates 122 can quickly rebound under the return spring 121, making it easy to remove the bottle body without affecting the next placement of the ampoule. The bottle body containing the medicine, with the cap broken off, can be removed from the bottle body positioning cylinder 1 by releasing the first pressure plate 14 while holding the bottle body with your hand, preventing the bottle body from falling downwards.

[0024] like Figure 3As shown, the bottle-breaking mechanism 2 includes a protective cap 21. The inner cavity of the protective cap 21 is vertically connected to the inner cavity of the bottle positioning cylinder 1. A movable ring 22 is rotatably connected to the outer wall of the protective cap 21. Springs 23 are fixedly installed on both the left and right sides of the inner wall of the protective cap 21. Pressure plates 24 are fixedly installed on the opposite ends of the two springs 23. Grinding wheels 25 are fixedly installed on the opposite surfaces of the two pressure plates 24. The opposite surfaces of the two grinding wheels 25 are provided with vertically connected arc-shaped grooves. A second pressure rod 26 is fixedly installed on both sides of the protective cover 21. The second pressure rod 26 is located inside the spring 23. The other ends of the two second pressure rods 26 pass through the left and right sides of the protective cover 21 respectively and are fixedly installed with second pressure plates 27. The second pressure plates 27 are located below the movable ring 22. The top of the protective cover 21 has a discharge hole 28 that passes through its inner cavity. The gap between the arc grooves of the two grinding wheels 25 and the gap between the opposite surfaces of the two arc clamping uprights 122 are on the same vertical line.

[0025] In use, insert the ampoule cap downwards into the inverted positioning cylinder 1 until it passes through the cylinder, causing the bottle neck to be engaged in the arc-shaped groove between the two opposing grinding wheels 25. The ampoule is then positioned by the compressive force generated by the grinding wheels 25 pressing against the spring 23 and the pressure plate 24. The positioning cylinder 1 can then be flipped back to its original position, with the protective cap 21 facing upwards. While the ampoule is held in place by the arc-shaped clamping plate 122, the other hand can simultaneously press the second pressure plate 27 with the index finger and thumb, thereby engaging the clamping plates on both sides of the bottle neck. The grinding wheel 25 is pressed against the neck of the bottle. Then, the protective cover 21 and the inner ring of the movable ring 22 are rotated to reciprocate. The grinding wheel 25 can be used to grind the neck of the ampoule bottle to avoid breakage when the bottle is broken directly. Then, the entire protective cover 21 can be flipped backward to pry open the bottle cap. At the same time, the first pressure plates 14 on both sides of the bottle positioning cylinder 1 also need to be pressed firmly to ensure the stability of the bottle. At the moment the protective cover 21 is flipped and the bottle cap is pried off, the hand holding the second pressure plate 27 can be released so that the broken bottle cap can fall out through the discharge hole 28.

[0026] like Figure 4 , Figure 5 As shown, an extension plate 221 is fixedly installed on the bottom rear side of the movable ring 22, and a T-shaped hinge plate 222 is hinged to the bottom of the extension plate 221. A fixing box 15 is fixedly installed above the rear end of the bottle positioning cylinder 1. The fixing box 15 is located above the first pressure plate 14. The fixing box 15 has a sliding chamber 151. The horizontal part of the T-shaped hinge plate 222 is slidably connected to the sliding chamber 151.

[0027] When the protective cover 21 is flipped, the T-shaped hinge plate 222 hinged to the bottom of the extension plate 221 will slide in the sliding compartment 151 opened in the fixed box 15, so that the protective cover 21 flips backward and moves downward at the same time, providing a good bottle-opening angle.

[0028] The working principle of this ampoule-breaking device will be explained in detail below.

[0029] like Figure 1-5 As shown, in use, the ampoule is inserted into the inverted positioning cylinder 1 with the cap facing down until it passes through the positioning cylinder 1, causing the neck of the ampoule to be locked in the arc-shaped groove between the two opposing surfaces of the grinding wheels 25. The ampoule is then positioned by the compressive force generated by the grinding wheels 25 being squeezed to both sides in conjunction with the pressure plate 24 and the spring 23. The positioning cylinder 1 can then be flipped back to its original position, with the protective cap 21 facing upwards. At this point, the first pressure plate 14 can be pressed simultaneously with the index finger and thumb, causing the two arc-shaped clamping plates 122 to move closer together using the first pressure rod 13. During this movement, the circular... The sliding connection between the two side slide plates 12 of the arc-shaped clamping plate 122 and the slide rod 11 remains stable. Simultaneously, the rubber pads 123 clamp the bottle body, preventing scratches and improving clamping stability. Meanwhile, the two slide plates 12 on the outer wall of the slide rod 11 compress the return spring 121. Once the first pressure plate 14 is released, the arc-shaped clamping plate 122 quickly rebounds as the return spring 121 returns, facilitating bottle removal without affecting the next ampoule placement. When the ampoule body is firmly clamped by the arc-shaped clamping plate 122, the other hand can simultaneously press the second pressure plate 122 using the index finger and thumb. The second pressure plate 27 can drive the grinding wheels 25 clamped on both sides of the bottle neck to press against the bottle neck. Then, by utilizing the rotational connection between the protective cover 21 and the inner ring of the movable ring 22, the entire protective cover 21 can be rotated back and forth. This allows the grinding wheels 25 to grind the bottle neck, preventing breakage when directly prying the bottle. Then, the entire protective cover 21 can be flipped backward to pry open the bottle cap. At the same time, the first pressure plates 14 on both sides of the bottle positioning cylinder 1 also need to be pressed firmly to ensure the stability of the bottle. When the protective cover 21 is flipped, the T-shaped hinge plate 222 hinged to the bottom of the extension plate 221 will open the fixing box 15. The slide chamber 151 is designed to slide, thereby causing the protective cover 21 to flip backward and move downward at the same time, providing a good bottle-breaking angle. At the moment the protective cover 21 flips and breaks off the bottle cap, the hand holding the second pressure plate 27 can be released, so that the broken bottle cap can fall out through the discharge hole 28. The bottle body containing the medicine, which has been broken off, is in the bottle body positioning cylinder 1. When the hand is holding the bottle body, the first pressure plate 14 can be released to remove it, preventing the bottle body from falling downward. At the same time, the four bottle body positioning cylinders 1 connected in parallel by the connecting plate 3 can hold ampoules of different sizes and break them one by one, improving the bottle-breaking efficiency.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
