Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an ampoule opener. Background Technology

[0002] In clinical nursing work, daily medication preparation is a demanding task. Currently, a large number of injection solutions and drug solvents are commonly packaged in glass ampoules. Therefore, safely and efficiently opening ampoules has become a key operation that nurses frequently perform on a daily basis.

[0003] Traditional opening methods rely on using a grinding wheel to scratch the slender "neck" of the ampoule, and then having caregivers break off the "head" by hand to open it, which can easily result in cuts to the caregivers' fingers.

[0004] Currently, the most common type of ampoule opener on the market is the handheld ampoule opener. While this type of opener offers some protection for the fingers, its dual-hold operation mode of "holding the ampoule in one hand and the opener in the other" presents the following technical problems: 1. During use, both of the nurse's hands are suspended in the air, lacking stable support, making it difficult to maintain precise alignment and force application. This not only easily leads to operational fatigue but also, if the force is applied incorrectly, can cause the opener to slip or the ampoule to break accidentally, still threatening operational safety; 2. In modern hospital management, to improve efficiency and safety, centralized medication preparation centers are commonly used for medication preparation. In this scenario, nurses need to open ampoules continuously and in large quantities. The advantage of handheld ampoule openers being easy for individuals to carry is no longer present. On the contrary, as a personal tool, it is easily forgotten or misplaced, which may force nurses to revert to unsafe manual operation when urgently needed because they cannot find the tool, creating a management loophole. Therefore, an ampoule opener is proposed. Utility Model Content

[0005] The purpose of this application is to provide an ampoule opener to solve the technical problems of poor operational stability and incompatibility with centralized drug dispensing mode in the dual-handling operation mode of handheld ampoule openers.

The drive handle is connected to the clamping mechanism. The drive handle can drive the clamping mechanism to move toward the fixed plate to apply a counterforce to the ampoule, thereby separating the ampoule body from the head.

[0007] In the above scheme, the scratch strip is slidably installed on the strip block and connected to the strip block through an elastic abutment mechanism.

[0008] Preferably, the scratch strip is slidably mounted on the strip block and connected to the strip block through an elastic abutment mechanism.

[0014] In the above scheme, the driving mechanism includes a first gear connected to the end of the rotating rod, and an arc-shaped rack is connected to the wall of the sliding groove, with the first gear meshing with the arc-shaped rack.

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings, and the structural features will be further detailed in conjunction with the working state. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figures 1 to 5 This application provides an ampoule opener, the technical solution of which is as follows: An ampoule opener, see reference Figures 1 to 5 The device includes a fixing plate 1, a mounting plate 2, two strip blocks 3, a scoring assembly 4, a clamping mechanism 5, and a drive handle 6. When a caregiver holds the ampoule body, passes its neck through the two strip blocks 3, and pushes the ampoule to slide so that it contacts the scoring assembly 4, a score can be made on the neck of the ampoule. After the caregiver continues to move the ampoule to the connection between the strip block 3 and the mounting plate 2, the clamping mechanism 5 can clamp the head of the ampoule above the strip block 3, and the drive handle 6 is used to drive the clamping mechanism 5 to move, so as to apply a counterforce to the ampoule, thereby separating the ampoule body from the head.

[0020] Fixing plate 1 is fixedly installed on the wall inside the intravenous medication preparation center. It should be noted that this application needs to be used in conjunction with the existing waste bin. The aforementioned waste bin is a standard feature in hospital intravenous medication preparation centers, usually close to the hospital wall, and is used to collect ampoule waste heads. Fixing plate 1 is installed on the wall above the waste bin, specifically by bolts / magnetic fixation to the wall, etc. A mounting plate 2 is vertically connected to it. Mounting plate 2 is a vertical plate, perpendicular to the ground.

[0021] Two strip blocks 3 are arranged in a parallel and spaced-apart configuration, and the two strip blocks 3 are located on the same horizontal line, and as shown... Figure 1 The two strip blocks 3 are spaced apart from the fixed plate 1, and their ends are perpendicularly connected to the mounting plate 2. It should be specifically noted that the distance between the two strip blocks 3 is less than the outer diameter of the ampoule body and greater than the outer diameter of the ampoule neck. The bottom side of the two strip blocks 3 is constructed with a slope 9 that can be movably overlapped with the top of the ampoule body.

[0022] The nurse can hold the ampoule with one hand and move it. The neck of the horizontally moving ampoule can pass through the two strip blocks 3. After the top of the ampoule touches the inclined surface 9, the nurse can push the ampoule to slide along the length of the strip block 3 toward the mounting plate 2.

[0023] The scoring component 4 is movably mounted on the strip block 3. The scoring component 4 can create scoring on the neck of the ampoule that moves between the two strip blocks 3. By creating weak points, it is easier to separate the ampoule body from the head later.

[0024] The clamping mechanism 5 is movably mounted on the mounting plate 2. When the ampoule moves to the connection between the strip block 3 and the mounting plate 2, the clamping mechanism 5 can clamp the head of the ampoule that is higher than the strip block 3.

[0025] The drive handle 6 is connected to the clamping mechanism 5. The drive handle 6 can drive the clamping mechanism 5 to move towards the fixed plate 1 to apply the opposite force to the ampoule, thereby separating the ampoule body from the head. It should be specifically noted that after the ampoule head is separated from the clamping mechanism 5, it can fall into the waste bin below through the gap between the strip block 3 and the fixed plate 1.

[0026] Compared with existing technologies, this application solves the stability and safety problems caused by hands being suspended in the air during long-term operation of handheld tools, while fundamentally eliminating the risk of the operator's hands coming into contact with the broken glass, achieving inherent safety. It also provides stable support through the fixing plate 1, and through the cooperation of the scoring component 4, the clamping mechanism 5 and the drive handle 6, it can ensure the precision and controllability of scoring and breaking actions, significantly improving operating efficiency and safety, and is suitable for the centralized drug preparation needs of intravenous drug preparation centers.

[0027] As one embodiment of this application, refer to Figure 1 and Figure 2 The scoring assembly 4 includes two scoring strips 41, which are symmetrically installed on opposite sides of two strip blocks 3. The scoring strips 41 can be made of silicon carbide. When the medical staff passes the ampoule neck through the two strip blocks 3 and drives the ampoule to slide between the two strip blocks 3, the two sides of the ampoule neck will come into contact with the two scoring strips 41, thereby creating a score on the ampoule neck. It should be noted that when the ampoule neck comes into contact with the scoring strips 41, the caregiver can also rotate the ampoule so that the scoring strips 41 can grind a ring-shaped score on the surface of the glass of the ampoule neck, thereby forming a ring-shaped fracture guide line, which facilitates the separation of the ampoule head from the bottle.

[0028] As one embodiment of this application, refer to Figure 1 and Figure 2 The scratch strip 41 is slidably mounted on the strip block 3 and connected to the strip block 3 through the elastic abutment mechanism 42. When the caregiver pushes the ampoule to move, the scratch strip 41 on the two strip blocks 3 will retract into the mounting groove 422 under the abutment of the ampoule neck, and squeeze the elastic abutment mechanism 42. The elastic abutment mechanism 42 will generate a reverse elastic force on the scratch strip 41, which will continuously and stably act on the scratch strip 41, so that it will always press tightly against the surface of the ampoule neck with a constant pressure. It should be noted that the elastic design of the elastic abutment mechanism 42 enables the component to automatically adapt to the slight differences in the neck diameter of ampoules of different brands and batches, ensuring that all types of ampoules can obtain effective scratches, and it has strong versatility.

[0029] As one embodiment of this application, refer to Figure 1 and Figure 2 The elastic abutment mechanism 42 includes a flexible block 421, a mounting groove 422, and a cover plate 423. The flexible block 421 is a rubber block that can deform. The mounting groove 422 is formed on the top of the strip block 3. The scratch strip 41 is slidably disposed in the mounting groove 422 and is connected to the inner wall of the mounting groove 422 through the flexible block 421. The two sides of the flexible block 421 are respectively adhered to the scratch strip 41 and the mounting groove 422. When the scratch strip 41 slides toward the inside of the mounting groove 422 under the abutment of the ampoule neck, the flexible block 421 can abut the scratch strip. 41 generates a reverse counterforce. The cover plate 423 is detachably installed on the top of the strip block 3. The cover plate 423 is detachably connected to the strip block 3 by a bolt assembly and covers the mounting groove 422. During long-term use, the edge of the scratch strip 41 will gradually become dull due to normal wear, resulting in a decrease in scratching efficiency and even affecting the fracture quality. By adopting the above design, when it is necessary to replace the scratch strip 41 or clean the inside of the mounting groove 422, the cover plate 423 can be removed to replace and maintain the scratch strip 41 and the flexible block 421.

[0030] As one embodiment of this application, refer to Figures 3 to 5 The clamping mechanism 5 includes a slider 51 that slides with the mounting plate 2. A rotating rod 52 is rotatably mounted on the slider 51. A U-shaped rod 53 is connected to the end of the rotating rod 52. Both ends of the U-shaped rod 53 are fitted with flexible sleeves 54 made of rubber. A driving mechanism 55 is provided at the end of the rotating rod 52. The driving mechanism 55 can drive the rotating rod 52 to rotate the U-shaped rod 53, so that the U-shaped rod 53 can clamp the inner neck of the ampoule. When the operating handle drives the slider 51 to move along its trajectory, the drive mechanism 55 fixed at the end of the rotating rod 52 will drive the rotating rod 52 and the U-shaped rod 53 to rotate synchronously. This rotational movement causes the U-shaped rod 53 to quickly rotate from its initial state, that is, the state in which the two ends of the U-shaped rod 53 are on the same horizontal plane, to the clamping state, that is, the two ends of the U-shaped rod 53 are at different heights and respectively abut against the two sides of the ampoule. In the clamping state, the flexible sleeve 54 on the inner side of the U-shaped rod 53 can clamp the head of the ampoule from both sides. As the slider 51 continues to move, the head of the ampoule that has been clamped by the U-shaped rod 53 will be pulled backward as a whole, thereby forming a pair of opposite forces between it and the bottle body blocked by the strip block 3, and finally achieving a precise and neat breakage of the ampoule at the preset scratch. It should be specifically noted that when the slider 51 slides away from the fixed plate 1, the drive mechanism 55 can drive the rotating rod 52 to rotate the U-shaped rod 53 in the opposite direction to reset it.

[0031] As one embodiment of this application, refer to Figure 3 and Figure 4 The drive handle 6 includes a movable grip 61, which is used to drive the slider 51 to slide. A fixed grip 62 is fixedly connected to the outside of the mounting plate 2. The fixed grip 62 serves as the force point for the caregiver. After the caregiver hooks the fixed grip 62 with four fingers, the movable grip 61 can be squeezed with the fixed grip 62 under the drive of the caregiver's thumb, thereby driving the slider 51 to move. A return spring 63 is connected to the end of the slider 51 and is connected to the mounting plate 2. The return spring 63 is used to provide elastic force to force the slider 51 to slide away from the fixed plate 1. When the slider 51 slides towards the fixed plate 1, the head of the ampoule separates from the bottle under the action of the U-shaped rod 53 on it. The slider 51 can be driven by the return spring 63 to drive the movable grip 61 to reset itself after the caregiver releases it.

[0032] As one embodiment of this application, refer to Figures 3 to 5The mounting plate 2 has a sliding groove 7, and the slider 51 is slidably disposed in the sliding groove 7. Its shape is adapted to the sliding groove 7 to eliminate unnecessary shaking. The return spring 63 is connected to the end of the sliding groove 7. This arrangement allows the return spring 63 to be completely contained inside the mounting plate 2, making the structure compact and protected. The sliding groove 7 has waist holes 8 on both sides. The drive shaft of the movable handle 61 and the rotating shaft of the rotating rod 52 pass through the two waist holes 8 respectively and are connected to the slider 51. The drive shaft of the movable handle 61 passes through one of the waist holes 8 and is connected to the slider 51. When the operator squeezes the movable handle 61, its force is directly transmitted to the slider 51 through this drive shaft, driving it to move along the sliding groove 7. The root of the rotating rod 52 passes through the other waist hole 8 and is rotatably connected to the slider 51 so that the rotation of the rotating rod 52 is not affected during the movement of the slider 51. In this application, by integrating the sliding guide, spring reset and motion transmission into the mounting plate 2, a compact module with good rigidity and small gap between moving parts is formed, which can effectively improve the rigidity and motion accuracy of the entire clamping and breaking mechanism. At the same time, the length of the waist hole 8 naturally constitutes the mechanical limit of the sliding stroke of the slider 51, preventing damage to the internal mechanism due to excessive operation, and can play a role in safety protection.

[0033] As one embodiment of this application, refer to Figures 3 to 5 Both the sliding groove 7 and the waist hole 8 are arc-shaped, and the movement trajectories of the slider 51 and the U-shaped rod 53 are also arc-shaped. The main purpose is that when the U-shaped rod 53 breaks the ampoule head, the ampoule head moves in an arc shape under the drive of the U-shaped rod 53. When using straight pulling or breaking by hand, the ampoule neck mainly bears tensile stress, which is prone to irregular cracking and a large number of glass particles. This design forces the ampoule head to move along an arc trajectory to simulate the progressive bending fracture process, so that the scored area of ​​the ampoule neck mainly bears uniform bending stress, so that the crack can be smoothly extended along the score line, thereby producing a relatively flat and smooth fracture surface, which can reduce the generation of glass fragments.

[0034] As one embodiment of this application, refer to Figure 4The drive mechanism 55 includes a first gear 551, which is connected to the end of the rotating rod 52 and can rotate together with the rotating rod 52. The wall of the sliding groove 7 is connected to an arc-shaped rack 552, which is concentric with the sliding groove 7. The first gear 551 meshes with the arc-shaped rack 552. When the operator drives the slider 51 to move along the arc-shaped sliding groove 7 through the drive handle 6, the rotating rod 52 fixed on the slider 51 will move accordingly. Since the first gear 551 installed at the end of the rotating rod 52 and the arc-shaped rack 552 fixed on the groove wall are always meshed, the movement of the slider 51 will force the first gear 551 to "roll" on the arc-shaped rack 552. By adopting the above design, the clamping action of the ampoule head and the sliding action of the slider 51 occur automatically and synchronously. No additional operation steps are required. The nursing staff only needs to perform a simple pinching action to automatically complete the continuous process of "forward-clamping-breaking", which greatly simplifies the operation and reduces the learning cost.

[0035] The usage process of this embodiment is as follows: 1. Insertion: The nurse holds the ampoule in one hand and inserts its neck through the two strip blocks 3; 2. Scratches: After the ampoule body comes into contact with the inclined surface 9, the caregiver pushes the ampoule to slide along the length of the strip block 3 toward the mounting plate 2, and scratches are made on the neck of the ampoule by the scratch strips 41 on the opposite sides of the two strip blocks 3. 3. Breakage: After the ampoule passes the scratch strip 41, the continuing to move ampoule will enter the inner side of the U-shaped rod 53 in the initial state. When the caregiver squeezes the movable handle 61, it will drive the slider 51 to move in an arc towards the fixed plate 1, and drive the rotating rod 52 on the slider 51 to rotate through the gear and the arc rack 552, so that the U-shaped rod 53 can rotate during the movement. When the U-shaped rod 53 rotates to the clamping state, it can tighten the ampoule head. Subsequently, the rotating rod 52 drives the U-shaped rod 53 to continue to rotate as the slider 51 moves, so that the U-shaped rod 53 can break the ampoule head. 4. Collection: The broken ampoule head can continue to move under the action of the U-shaped rod 53 and fall into the waste bin below through the gap between the strip block 3 and the fixed plate 1; 5. Reset: After the nursing staff releases the movable handle 61, the slider 51, under the action of the reset spring 63, can drive the movable handle 61 and the U-shaped rod 53 to reset, so that the operation can be performed again next time.
