Description

Technical Field

[0001] This invention belongs to the technical field of ampoule bottle safety opening devices, specifically a safety protection device to prevent ampoule bottle residue from spilling. Background Technology

[0002] Ampoules are small glass containers used to encapsulate injectable medications. They are made of neutral borosilicate glass using a tubular process and have a pre-opened ring at the neck for easy breaking. The inner wall is siliconized to reduce drug adsorption, and sterile isolation is achieved through high-temperature sealing. They are commonly used containers to ensure the stability of injectable drugs.

[0003] In routine medical procedures, opening ampoules is a frequent and fundamental action. Medical staff usually break the neck of the ampoule by hand. At that moment, the ampoule breaks due to stress concentration, and some of the glass at the crack will fly out in the form of fragments. This can easily cut the fingers of medical staff and pose a safety hazard to their daily care work. Therefore, it needs to be improved. Summary of the Invention

The other end of each hinge plate is hinged to a movable plate. The number of movable plates is five, and the outer surface of each of the five movable plates is movably connected to the inner surface of the first mounting box.

[0008] In a preferred embodiment of the present invention, a threaded rod is movably sleeved on the left surface of the first mounting box.

The outer surface of the threaded rod is threadedly sleeved on the inner surface of the movable plate. A handle located on the right side of the first mounting box is fixedly sleeved on the outer surface of the threaded rod. The outer surface of the handle is movably connected to the first mounting box.

[0009] As a preferred embodiment of the present invention, a guide rod located below the first threaded rod is fixedly sleeved on the left surface of the first mounting box. The right end of the guide rod passes through the first mounting box and the movable plate in sequence and extends to the right surface of the first mounting box. The outer surface of the guide rod and the inner surface of the movable plate are movably sleeved.

[0010] In a preferred embodiment of the present invention, a second mounting box is fixedly connected to the upper surface of the first mounting box, a movable block is movably connected to the inner surface of the second mounting box, a curved rod is fixedly connected to the front surface of the movable block, the outer surface of the curved rod is movably connected to the inner surface of the second mounting box, a bolt is fixedly connected to the other end of the curved rod, a frosted plate is movably sleeved on the outer surface of the bolt, a hexagonal nut is movably connected to the lower surface of the frosted plate, and the inner surface of the hexagonal nut is threadedly sleeved on the outer surface of the bolt.

[0011] In a preferred embodiment of the present invention, a connecting plate is fixedly sleeved on the outer surface of the crank rod, the rear surface of the connecting plate is movably connected to the front surface of the second mounting box, a third mounting box is fixedly connected to the upper surface of the second mounting box, a long plate is movably connected to the inner surface of the third mounting box, a telescopic rod is fixedly connected to the outer surface of the long plate, and the front end of the telescopic rod penetrates the third mounting box and extends to the outside of the third mounting box and is fixedly connected to a pressing plate.

[0012] As a preferred embodiment of the present invention, a servo motor is fixedly mounted on the lower surface of the third mounting box, and a round shaft is fixedly sleeved on the other end of the output shaft of the first servo motor. The top end of the outer surface of the round shaft penetrates the third mounting box and extends into the interior of the third mounting box, and a drive rod is fixedly sleeved thereon. A driven rod is hinged to the other end of the drive rod, and the other end of the driven rod is hinged to the rear surface of the long plate.

[0013] As a preferred embodiment of the present invention, a second servo motor is fixedly mounted on the left surface of the second mounting box, and a second threaded rod is fixedly sleeved on the other end of the output shaft of the second servo motor.

This invention, by setting up an ampoule, a circular sleeve, a connecting plate, and a connecting line, ensures that when the circular sleeve covers the ampoule, the inner surface of the sleeve will block the neck of the ampoule. If the ampoule is broken at this time, the flying glass fragments generated at the neck of the ampoule will be blocked by the circular sleeve, thereby preventing the glass fragments from flying and cutting the fingers of medical staff. The design of the connecting line also ensures that the circular sleeve and the top of the ampoule will not fall off and be lost if they are broken off.

[0015] 2. This invention, by setting up a fixed clamping block, a first mounting box, a hinge plate, and a movable plate, allows the movable plate to move to the left when medical personnel rotate the first threaded rod. During this process, the hinge plate rotates, and the other end of the hinge plate drives the movable clamping block, causing it to move towards the ampoule. Ultimately, the ampoule is clamped by the fixed clamping block and the movable clamping block, thus preventing the ampoule from moving or rotating during opening.

[0016] 3. This invention, by setting up a long plate, a pressing plate, an active rod, and a driven rod, allows the circular shaft and the active rod to rotate when the first servo motor is started. The rotation of the active rod drives the driven rod, causing it to rotate as well. Simultaneously, the other end of the driven rod drives the long plate, causing the long plate, the telescopic rod, and the pressing plate to move towards the connecting plate. Finally, during this movement, the pressing plate applies force to the ampoule through the circular sleeve, breaking the ampoule from the neck. This not only ensures the safe opening of the ampoule but also reduces the daily physical exertion of medical staff. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, this embodiment of the invention provides a safety protection device to prevent ampoule splattering, including a trapezoidal block 1, a triangular base 2 fixedly connected to the lower surface of the trapezoidal block 1, an ampoule 3 movably connected to the inner surface of the trapezoidal block 1, a circular sleeve 4 movably fitted onto the outer surface of the ampoule 3 above the trapezoidal block 1, a connecting plate 5 fixedly connected to the top of the circular sleeve 4, the top of the ampoule 3 movably connected to the lower surface of the connecting plate 5, and connecting lines 6 fixedly connected to both the left and right sides of the upper surface of the connecting plate 5, with two connecting lines 6, the other ends of which are movably connected to the outer surfaces of the left and right sides of the trapezoidal block 1 respectively.

[0021] The lower side of the inner surface of the sleeve 4 will cover the neck of the ampoule 3, thus ensuring that when the ampoule 3 is broken, the glass fragments generated at the broken part of the neck of the ampoule 3 will not fly to the outside of the sleeve 4. The design of the connecting line 6 ensures that the connecting plate 5 will not be accidentally lost.

[0022] Among them, the rear surface of the trapezoidal block 1 is fixedly connected to the No. 1 mounting box 8, the lower surface of the No. 1 mounting box 8 is fixedly connected to the upper surface of the triangular base 2, the front side of the inner surface of the trapezoidal block 1 is fixedly connected to the fixed clamping block 7, there are five fixed clamping blocks 7, the inner surface of the five fixed clamping blocks 7 are the same size, the rear side of the inner surface of the trapezoidal block 1 is movably connected to the movable clamping block 9, the outer surface of the movable clamping block 9 is movably connected to the inner surface of the No. 1 mounting box 8, and both the fixed clamping block 7 and the movable clamping block 9 are movably connected to the outer surface of the ampoule 3.

[0023] The surfaces of the fixed clamping block 7 and the ampoule 3 that come into contact with each other, as well as the surfaces of the movable clamping block 9 and the ampoule 3 that come into contact with each other, are rough. This makes it impossible for the ampoule 3 to move or rotate when it is clamped by the fixed clamping block 7 and the movable clamping block 9 due to the large frictional force.

[0024] Among them, there are five movable clamping blocks 9, and each of the five movable clamping blocks 9 has a hinge plate 10 hinged to its rear surface. The other end of the hinge plate 10 is hinged to a movable plate 11. There are five movable plates 11, and the outer surface of each of the five movable plates 11 is movably connected to the inner surface of the first mounting box 8.

[0025] The movement of the movable plate 11 will cause the hinge plate 10 to move, thereby causing the other end of the hinge plate 10 to drive the movable clamping block 9, so that the movable clamping block 9 moves back and forth along the inner surface of the trapezoidal block 1.

[0026] Among them, the left surface of the first mounting box 8 is movably sleeved with a first threaded rod 12. The right end of the first threaded rod 12 passes through the first mounting box 8 and the movable plate 11 in sequence and extends to the right surface of the first mounting box 8 and is fixedly connected to a limiting plate 13. The outer surface of the first threaded rod 12 and the inner surface of the movable plate 11 are threadedly sleeved. The outer surface of the first threaded rod 12 is fixedly sleeved with a handle 14 located on the right side of the first mounting box 8. The outer surface of the handle 14 is movably connected to the first mounting box 8.

[0027] The rotation of the first threaded rod 12 will drive the movable plate 11, thereby causing the five movable plates 11 to move left and right.

[0028] Among them, the left surface of the first mounting box 8 is fixedly sleeved with a guide rod 15 located below the first threaded rod 12. The right end of the guide rod 15 passes through the first mounting box 8 and the movable plate 11 in sequence and extends to the right surface of the first mounting box 8. The outer surface of the guide rod 15 and the inner surface of the movable plate 11 are movably sleeved.

[0029] The guide rod 15 is designed to restrict the direction of movement of the movable plate 11.

[0030] Among them, the upper surface of the first mounting box 8 is fixedly connected to the second mounting box 16, the inner surface of the second mounting box 16 is movably connected to the movable block 17, the front surface of the movable block 17 is fixedly connected to the curved rod 18, the outer surface of the curved rod 18 is movably connected to the inner surface of the second mounting box 16, the other end of the curved rod 18 is fixedly connected to the bolt 19, the outer surface of the bolt 19 is movably sleeved with the abrasive plate 20, the lower surface of the abrasive plate 20 is movably connected to the hexagonal nut 21, and the inner surface of the hexagonal nut 21 is threadedly sleeved with the outer surface of the bolt 19.

[0031] The design of the hexagonal nut 21 and bolt 19 serves to clamp and fix the abrasive plate 20.

[0032] Among them, the outer surface of the curved rod 18 is fixedly sleeved with a sleeve plate 22, the rear surface of the sleeve plate 22 is movably connected to the front surface of the second mounting box 16, the upper surface of the second mounting box 16 is fixedly connected to the third mounting box 23, the inner surface of the third mounting box 23 is movably connected to a long plate 24, the outer surface of the long plate 24 is fixedly connected to a telescopic rod 25, the front end of the telescopic rod 25 passes through the third mounting box 23 and extends to the outside of the third mounting box 23 and is fixedly connected to a pressing plate 26.

[0033] The telescopic rod 25 can move back and forth along the inner surface of the No. 3 mounting box 23, with the long plate 24 limiting the forward distance of the extrusion plate 26.

[0034] Among them, a servo motor 27 is fixedly installed on the lower surface of the third mounting box 23. A round shaft 28 is fixedly sleeved on the other end of the output shaft of the servo motor 27. The top end of the outer surface of the round shaft 28 passes through the third mounting box 23 and extends into the interior of the third mounting box 23, and is fixedly sleeved with an active rod 29. A driven rod 30 is hinged to the other end of the active rod 29. The other end of the driven rod 30 is hinged to the rear surface of the long plate 24.

[0035] When the first servo motor 27 is started, the circular shaft 28, the driving rod 29 and the driven rod 30 will start to rotate, thereby causing the long plate 24 to move back and forth as a whole.

[0036] The second servo motor 31 is fixedly installed on the left surface of the second mounting box 16. The other end of the output shaft of the second servo motor 31 is fixedly sleeved with the second threaded rod 32. The right end of the second threaded rod 32 passes through the second mounting box 16 and the movable block 17 in sequence and extends to the right surface of the second mounting box 16. The outer surface of the second threaded rod 32 and the inner surface of the movable block 17 are threaded together.

[0037] When the second threaded rod 32 starts to rotate, the entire movable block 17 will begin to move to the right under the drive of the second threaded rod 32.

[0038] Working principle and usage process: First, the medical staff places the ampoule 3 between the fixed clamping block 7 and the movable clamping block 9, ensuring that the blue dot on the outer surface of the ampoule 3 faces the compression plate 26. Then, the medical staff rotates the handle 14, causing the handle 14 and the first threaded rod 12 to rotate as a whole. At this time, the movable plate 11 will start to move to the left under the action of the first threaded rod 12. At the same time, the hinge plate 10 will also rotate with the movement of the movable plate 11. The other end of the hinge plate 10 will drive the movable clamping block 9, thereby causing the movable clamping block 9 to start moving towards the ampoule 3. Finally, the movable clamping block 9 and the fixed clamping block 7 will clamp the ampoule 3, thus ensuring that the ampoule 3 will not move during the process of being scratched by the abrasive plate 20 or being opened.

[0039] Then, the medical staff activates the second servo motor 31. As the second servo motor 31 operates, the second threaded rod 32 begins to rotate, causing the movable block 17 to move to the right. During this process, the abrasive disc 20 slightly scratches the neck of the ampoule 3, reducing the difficulty of opening the ampoule 3. Then, the medical staff places the sleeve 4 on top of the ampoule 3 and activates the first servo motor 27. As the first servo motor 27 operates, the circular shaft 28, the driving rod 29, and the driven rod 3... The ampoule 3 will begin to rotate. At the same time, the long plate 24, the telescopic rod 25, and the squeezing plate 26 will all move forward under the drive of the driven rod 30. When the squeezing plate 26 contacts the circular sleeve 4, the force on the neck of the ampoule 3 from the squeezing plate 26 will gradually increase. Eventually, the ampoule 3 will break from the scratch on the neck. During this process, the glass fragments on the neck of the ampoule 3 will be blocked by the circular sleeve 4, thus preventing the glass fragments from flying everywhere and fully ensuring the safety of medical staff.
