Description

Technical Field

[0001] The utility model relates to the technical field of bottle openers, in particular to a safe and pollution-free multifunctional ampoule bottle opener. Background Art

[0002] An ampoule is a fusible, sealable, rigid glass container commonly used to store injectable medications, vaccines, and serums. Whether the liquid inside the ampoule is contaminated is directly related to the patient's health and life, and aseptic opening of the ampoule is crucial, ensuring that the liquid inside the ampoule is free of contamination between opening and infusion.

[0003] Currently, there are various ampoule opening devices on the market, but most of them are difficult to ensure that the bottle is opened sterilely or that there are no infected objects above the bottle. For example, patent publication number CN214734346U discloses an ampoule bottle opener, which includes a cutting mechanism, a bottle opening mechanism, a lever handle, a sliding member, and a body. The body is provided with a grip portion, the middle portion of the lever handle is hinged to the body, the upper end of the lever handle is used to push the sliding member to slide, the cutting mechanism is rotatably connected to the body, and the sliding member is used to push the cutting mechanism to swing. The body is also provided with a positioning member, the bottle opening mechanism is located above the positioning member, the bottle opening mechanism includes a breaking plate and a clamping member located in front of the breaking plate, the upper ends of the breaking plate and the upper ends of the clamping member are respectively hinged to the body, the sliding member is used to push the breaking plate to swing, and the swinging of the breaking plate drives the clamping member to swing. Although the aforementioned ampoule opener can open the ampoule, some structural parts inevitably remain on the ampoule body after opening. These structural parts are undoubtedly a serious source of contamination for the opened ampoule, and thus cannot guarantee that the liquid medicine in the ampoule will not be contaminated after opening.

[0004] In addition, in order to achieve the synchronous opening of multiple ampoules, the conventional practice is to cluster the structure of the single ampoule opener. Although this can achieve the synchronous opening of multiple ampoules, the corresponding parts will inevitably increase. For example, the number of cutting mechanisms and ampoules needs to be consistent, resulting in the overall structure of the bottle opener being relatively complex, large in size, and light in weight, which is not conducive to carrying and using, and the cost is also relatively high.

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] See also Figures 1 to 6 As shown, a safe and pollution-free multifunctional ampoule bottle opener includes a main seat 1, a clamping arm 2 and a breaker.

[0040] The main base 1 is provided with an ampoule placement portion 101. The ampoule placement portion 101 is a groove structure provided on one side of the main base and extending through the top and bottom surfaces thereof. It is provided with at least two ampoule placement positions 1011 (the ampoule placement positions 1011 are adapted to the body of the ampoule bottle a). In this embodiment, for example, the ampoule placement portion 101 is provided with two ampoule placement positions 1011, and the two ampoule placement positions 1011 are suitable for accommodating ampoules a of different specifications.

[0041] The clamping arms 2 are flexible structural members. The number of clamping arms 2 matches the number of ampoule placement positions 1011 provided in the ampoule placement portion 101. The clamping arms 2 are fixed to the top surface of the main base 1 and are located above the ampoule placement portion 101, corresponding to each ampoule placement position 1011. In this embodiment, the clamping arms 2 are, for example, rubber members.

[0042] The breaker includes a breaking arm 3 and a linear displacement device. The linear displacement device is arranged on the main seat 1. The side of the breaking arm 3 is connected to the linear displacement device and is located above the main seat 1. The linear displacement device is used to drive the breaking arm 3 to move translationally toward the clamping arm 2, breaking the bottleneck of the ampoule bottle a placed in the ampoule bottle placement part 101, and at the same time clamping the nipple part of the ampoule bottle a with the clamping arm 2 and pushing it to the front side of the ampoule bottle placement part 101.

[0043] The main base 1 also includes a cutting device disposed on the top surface thereof. The cutting device is configured to cut the neck of the ampoule A when the breaking arm 3 is not in contact with the ampoule A placed in the ampoule placement portion 101. The cutting device comprises a cutter 4, which is rotatably mounted on the main base 1 via a rotating shaft 12, and a first drive mechanism connected to the rotating shaft 12. The first drive mechanism is configured to rotate the cutter 4. Each of the ampoule placement positions 1011 provided in the ampoule placement portion 101 is located within the motion path of the cutter head of the cutter 4. That is, during its motion, the cutter 4 can sequentially cut the neck of the ampoule A placed in the corresponding position 1 of the ampoule placement position 1.

[0044] In the above technical solution, in order to ensure that the ampoule bottle a is accurately placed in the ampoule bottle placement portion 101, the preferred design is as follows:

[0045] A stopper plate 9 is provided on the top surface of the main base 1, in front of the ampoule placement portion 101. A stopper opening 901 is formed at the position corresponding to each clamping arm 2. The stopper opening 901 is V-shaped. When ampoule a is placed in the ampoule placement portion 101, the neck of the ampoule a is locked into the stopper opening 901, keeping the ampoule a relatively fixed and virtually motionless.

[0046] In the above technical solution, in order to ensure that the breaking arm 3 and the clamping arm 2 can well clamp the nipple part of the ampoule bottle a, the preferred design is as follows:

[0047] A first limiting groove 201 is provided on the side of the clamping arm 2 near the breaking arm 3, and a second limiting groove 301 is provided on the side of the breaking arm 3 near the clamping arm 2. The number of second limiting grooves 301 matches the number of clamping arms 2, and the positions of the second limiting grooves 301 correspond one-to-one with the first limiting grooves 201 provided on each clamping arm. When the breaking arm 3 and the clamping arm 2 clamp the nipple portion of the ampoule bottle a, the nipple portion of the ampoule bottle a is embedded in the first limiting groove 201 and the second limiting groove 301, thereby effectively limiting the nipple portion of the ampoule bottle a.

[0048] The breaking arm 3 is in an inclined state, and its upper side is closer to the clamping arm 2 than its lower side. When the breaking arm 3 and the clamping arm 2 clamp the nipple portion of the ampoule bottle a and push it toward the front side of the ampoule bottle placement portion 101, the clamping arm 2 is in a bent state, and the breaking arm 3 in the inclined state can remain relatively parallel to the clamping arm 2 at this time, thereby forming a good clamping position for the nipple portion of the ampoule bottle a.

[0049] In this embodiment, illustratively, the first limiting groove 201 and the second limiting groove 301 are V-shaped groove structures or arc-shaped groove structures; the inclination angle of the breaking arm 3 is reasonably designed according to the final bending shape of the clamping arm 2.

[0050] See also Figures 1 to 10 As shown, as one embodiment, the linear displacement device includes a slider 11 and a second driving mechanism. A slide groove 102 adapted to the slider 11 is provided in the main seat 1. The slider 11 is arranged in the slide groove 102. The side of the breaking arm 3 is connected to the slider 11. The second driving mechanism is arranged on the main seat 1, and the second driving mechanism is used to drive the slider 11 to slide in the slide groove 102.

[0051] Specifically, the second driving mechanism includes a first handle 5, a second handle 6 and a first reset assembly, wherein:

[0052] The first handle 5 is fixedly connected to the main seat 1;

[0053] The middle portion of the second handle 6 is rotatably connected to the main seat 1. The front end of the second handle 6 extends into the slide groove 102 provided in the main seat 1 and abuts against the slider 11. When the second handle 6 is rotated, the front end of the second handle 6 pushes the slider 11 to slide forward from the initial position in the slide groove 102.

[0054] A limit block 10 is provided in the slide groove 102 , and a first reset component is provided between the limit block 10 and the slider 11 . The first reset component is used to drive the slider 11 back to its initial position after the second handle 6 pushes the slider 11 to slide to a specified position.

[0055] More specifically, the first reset assembly includes a rotary compression spring 19 and a guide rod 18. The slider 11 is provided with a receiving cavity 1101 that mates with the stop block 10. The stop block 10 is provided with a through hole 1001 that mates with the guide rod 18. The guide rod 18 is fixed in the receiving cavity 1101. The rotary compression spring 19 is passed through the guide rod 18, with one end abutting against the end surface of the receiving cavity 1101 and the other end abutting against the stop block 10. As the front end of the second handle 6 pushes the slider 11 to slide forward in the slide groove 102 from its initial position, the stop block 10 can enter the receiving cavity 1101 provided on the slider 11, and the guide rod 18 can enter the through hole 1001 provided on the stop block 10.

[0056] To prevent foreign matter from entering the chute 102, the preferred design is as follows:

[0057] A protective cover 7 is provided on the slider 11 and is located above the main seat 1. When the slider 11 slides in the slide groove 102, the protective cover 7 always covers the slide groove 102.

[0058] In order to ensure that the slider 11 has sufficient sliding space without increasing the volume of the main seat 1, the slide groove 102 extends forward through the front side of the main seat 1, so that the slider 11 can slide out of the slide groove 102. Similarly, to prevent foreign matter from entering the slide groove 102, the preferred design is as follows:

[0059] A protective door 8 is installed on the front side of the main seat 1, corresponding to the chute 102. The protective door 8 is rotatably connected to the main seat 1 via an automatic reset shaft. The automatic reset shaft generally includes a rotating shaft and a reset torsion spring. The reset torsion spring is installed on the rotating shaft, with one end abutting the protective door 8 and the other end abutting the main seat 1. The slider 11 slides out of the chute 102, pushing the protective door 8 open. The slider 11 slides back into the chute 102, and the protective door 8 automatically closes.

[0060] See also Figures 4-10 As shown, as one of the embodiments, a sleeve 13 is fixedly provided on the rotating shaft 12, and the first driving mechanism includes a first driving member 14 and a second driving member 15. The first driving member 14 is connected to the sleeve 13, and the second driving member 15 is connected to the slider 11, and the first driving member 14 and the second driving member 15 are abutted against each other. When the slider 11 slides forward from the initial position in the slide groove 102, the first driving member 15 is pushed to rotate by the second driving member 14, thereby causing the rotating shaft 12 to drive the tool 4 to rotate from the initial position to the specified position.

[0061] To achieve automatic resetting of the tool, a second resetting assembly is also included, comprising a rotary torsion spring 16 and a stopper 17. The rotary torsion spring 16 is threaded through the rotating shaft 12. The stopper 17 is connected to a sleeve 13 provided on the rotating shaft 12 and abuts against one end of the rotary torsion spring 16, while the other end of the rotary torsion spring 16 abuts against the main base 1. As the rotating shaft 12 drives the tool 4 to rotate from its initial position to its designated position, it also drives the stopper 17 to rotate and causes the rotary torsion spring 16 to store energy. As the tool 4 returns from its designated position to its initial position, the rotary torsion spring 16 drives the rotating shaft 12 to rotate the tool 4.

[0062] In this embodiment, for example, there is a cavity in the main seat 1, and the cavity in the main seat 1 is connected to the slide groove 102, and the rotating shaft 12, the sleeve 13, the first driving member 14, the second driving member 15, the rotary torsion spring 16 and the limit member 17 are all in the cavity of the main seat 1.

[0063] The use process of this multifunctional ampoule opener is as follows:

[0064] Place ampoules a of different specifications in the corresponding ampoule placement positions 1011 in the ampoule placement portion 101, so that the bottleneck of the ampoule a is embedded in the limiting opening 901;

[0065] Holding the first handle 5, pull back the second handle 6. The front end of the second handle 6 pushes the slider 11 to slide forward from its initial position in the slide groove 102. During this process, on the one hand, the slider 11 drives the cutter 4 to rotate, cutting the bottleneck of each ampoule a in sequence. On the other hand, the slider 11 drives the breaking arm 3 to move horizontally toward the clamping arm 2, breaking the bottleneck of each ampoule a. At the same time, the slider 11 and the clamping arm 2 clamp the nipple of each ampoule a and push it toward the front side of the ampoule placement section 101. At this point, the slider 11 slides to the designated position, and there are no structural parts on the body of the ampoule a.

[0066] Take out the body of each ampoule bottle a laterally;

[0067] Align the recovery tray and release the second handle 6. The rotary compression spring 19 drives the slider 11 back to the initial position, thereby driving the breaking arm 3 to move translationally away from the clamping arm 2. The nipple part of the ampoule a falls onto the recovery tray. At the same time, the rotary torsion spring 16 drives the cutter 4 back to the initial position.

[0068] The ampoule placement portion 101 and the clamping arm 2, breaking arm 3 and other structural parts are disinfected, and the next batch of ampoules a are waiting to be opened.

[0069] Of course, the above are only preferred implementation methods of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes based on the principles of the present invention should be included in the scope of protection of the present invention.
