Abstract
Description
Technical Field
[0001] This invention relates to the field of bottle opening device technology, and in particular to an ampoule bottle opening device and opening method. Background Technology
[0002] Ampoules are small, sealed glass bottles commonly used to store liquid medications, especially injectable solutions. They offer excellent sealing and stability, effectively protecting medications from external contamination. Before use, flick the medication from the tip of the ampoule into the body. Make a small saw mark on the neck of the ampoule with a grinding wheel. After disinfecting the neck with 75% ethanol, place a sterile gauze or cotton ball under the neck and break the ampoule. If the ampoule neck has a blue mark, a saw mark is unnecessary; after disinfecting the neck, simply break the ampoule with a sterile gauze or cotton ball under the neck. Tapping the ampoule during opening can easily cause liquid to leak out, resulting in waste. When ampoules are cut using an opener, scissors, or a grinding wheel, glass powder fragments are easily generated. These fragments can easily fall into the ampoule and be drawn into a syringe along with the liquid, eventually being injected into the body. They can directly block blood vessels, causing insufficient local blood supply, tissue ischemia, hypoxia, and even necrosis. When these particles enter the pulmonary capillaries, they can cause macrophage proliferation, including the formation of pulmonary granulomas, affecting lung function. In addition, if red blood cells aggregate on the particles, they can form thrombi, causing vascular embolism and phlebitis. The particles can also irritate tissues, causing inflammation or forming masses.
[0003] The currently pending patent CN202110430926.4 discloses a fully automatic heated ampoule opening device for biological experiments. It includes an opening device working unit and a working frame. The working frame has an array of working slots, each containing a power supply post. The opening device working unit has a power port at its bottom and is movably inserted into a corresponding working slot on the working frame. The opening device working unit includes a rotary locking heating device, a cooling device, and a main body. The rotary locking heating device is installed in a front support of the main body, and the cooling device is installed on the outer ring. An ampoule placement slot is located in the middle of the opening device working unit. This patent allows ampoules to be opened on demand, is suitable for unmanned operation, and meets the needs of opening ampoules in automated laboratory experiments. While the aforementioned patents utilize heating and cooling to open ampoules, preventing debris from entering the body, the separate heating and cooling systems, multiple cooling nozzles around the ampoule, and the need for a separate robotic arm to clean broken glass result in a complex structure and uneven cooling. Furthermore, heating and cooling alone are insufficient to effectively open the ampoule; manual breaking of the cap is still required, leading to low automation and inconvenience. Summary of the Invention

[0018] S4. The first solenoid valve opens, and the low-temperature chilled water in the refrigerator enters the contact ring through the main inlet pipe and the branch inlet pipe. The contact ring rapidly cools the contact surface. Based on the principle of thermal expansion and contraction and the effect of thermal stress, the ampoule cap breaks uniformly at the contact point with the contact ring. Subsequently, the low-temperature chilled water flows back into the refrigerator through the branch outlet pipe and the main outlet pipe. After cooling is completed, the first solenoid valve and the refrigerator are closed.
[0019] S5. The telescopic hinge retracts, the ampoule moves downward, the ampoule separates from the contact ring, and the spring returns to its original position; the motor reverses, the motor drives the slide block to slide outward along the lead screw, the ampoule slides outward, the ampoule cap contacts the baffle, the baffle is restricted by the slotted top hinge and cannot rotate, the ampoule cap, after being rapidly heated and cooled and evenly broken, falls into the collection frame under the action of the baffle, and the ampoule body moves to the pick-and-place area, waiting to be used;
[0020] S6. The air compressor starts, the second solenoid valve opens, and compressed air enters the water inlet main pipe through the air inlet pipe. The low-temperature cold water in the water inlet main pipe flows back into the refrigeration unit through the water inlet branch pipe, contact ring, water outlet branch pipe, and water outlet main pipe; waiting for the next bottle opening operation.
[0021] The advantages and positive effects of the ampoule opening device and opening method described in this invention are:
[0022] 1. This invention uses a contact ring to contact the ampoule cap, and an electromagnetic induction heating coil to rapidly heat the contact ring. The heated contact ring then rapidly heats the ampoule, improving the uniformity and efficiency of ampoule heating. The contact ring is connected to a chiller via an inlet and outlet water pipe, allowing for rapid cooling of the ampoule. This rapid heating and cooling of the ampoule through the contact ring simplifies the structure, improves the heating and cooling effect, enhances the flatness of the fracture surfaces of the ampoule body and cap, and prevents glass powder fragments from entering the liquid during cutting.
[0023] 2. Springs are installed on the inlet and outlet branch pipes. The springs tightly press the contact ring against the upper part of the ampoule, ensuring full contact between the contact ring and the ampoule. This improves the heating and cooling effect of the ampoule and provides important technical support for the uniform breakage of the ampoule cap.
[0024] 3. A baffle is provided on the fixed plate. The inner surface of the top of the baffle is hinged to the fixed plate by a simple hinge. The top surface of the slot has a limiting effect on the outward rotation of the baffle, so that the baffle can only rotate or reset inward into the shell, but cannot rotate outward into the shell. This separates the bottle body and the cap during the ampoule reset process, realizing automatic opening of the ampoule and ensuring the opening effect of the ampoule. The structure is simple, easy to use, and the effect is obvious.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0044] like Figure 1-3As shown. An ampoule opening device includes a housing 1, with a base 2 supporting the bottom of the housing 1. Inside the housing 1 is a movable frame 3, a rectangular frame for top opening. A fixing rod 8 is fixedly mounted on the top of the movable frame 3, and receiving boxes 9 are fixedly mounted on the fixing rod 8. Five receiving boxes 9 of different sizes are mounted on the fixing rod 8, respectively for holding 1mL, 2mL, 5mL, 10mL, and 20mL ampoules, meeting the opening needs of various ampoule sizes and allowing simultaneous opening of multiple sizes. The inner diameter of the receiving box 9 is slightly larger than the outer diameter of the ampoule, ensuring the ampoule is stably inserted into the receiving box 9.

[0045] The housing 1 is equipped with a control panel 5 and a controller, which are electrically connected. A battery can be installed inside the housing 1 as needed, or it can be directly connected to an external AC power source via a plug. Both the battery and the plug are electrically connected to the controller. The control panel 5 has a one-button automatic operation button, with buttons for 1mL, 2mL, 5mL, 10mL, and 20mL ampoules.
[0046] like Figure 13 , Figure 14 As shown. A baffle structure is provided on the housing 1 to separate the ampoule body and cap from any ampoule that breaks after heating and cooling. A collection frame 4 is located below the baffle structure. The glass caps in the collection frame 4 are cleaned periodically. The baffle structure includes a fixing plate 6, which is fixedly mounted on the inner wall of the housing 1. One side of the fixing plate 6 is a placement area for inserting or removing ampoules from the receiving box 9. The fixing plate 6 has slots corresponding to the ampoules, and baffles 7 are installed in these slots. The inner surface of the top of the baffle 7 is hinged to the fixing plate 6. The top surface of the slot limits the outward rotation of the baffle 7, ensuring that the baffle 7 can only rotate inward or reset within the housing 1, and cannot rotate outward. This separates the broken ampoule body and cap during the ampoule reset process, achieving automatic ampoule opening and ensuring effective ampoule opening.
[0047] like Figure 4-8 As shown, the housing 1 is equipped with a heating / cooling mechanism for rapidly heating and cooling the ampoule caps. The heating / cooling mechanism includes a support plate 10, which is fixed to the inner wall of the housing 1 by a support frame 11. A contact ring 22 is provided at one end of the support plate 10 near the fixing plate 6, which contacts the ampoule cap. The ampoule cap is inserted into the contact ring 22. Each contact ring 22 corresponds to one ampoule, and the inner diameter of the contact ring 22 is adapted to different sizes of ampoules, ensuring sufficient contact between the ampoule and the contact ring 22.
[0048] Contact ring 22 is connected to the refrigeration structure for rapid cooling of the ampoules. The refrigeration structure includes a refrigerator 12, which is fixedly mounted on the support plate 10. The refrigerator 12 is electrically connected to the controller.

[0049] An air inlet pipe 25 is installed on the main water inlet pipe 17, and the air inlet pipe 25 is connected to the air outlet of the air compressor 14. The air compressor 14 is fixedly mounted on the support plate 10. A second solenoid valve 27 is installed on the air inlet pipe 25 to control the opening and closing of the air inlet pipe 25. The second solenoid valve 27 and the air compressor 14 are electrically connected to the controller using existing technology as needed. Through the air compressor 14, all the cold water in the main water inlet pipe 17, the branch water inlet pipe 18, the contact ring 22, the branch water outlet pipe 19, and the main water outlet pipe 20 can flow back into the refrigeration unit 12, keeping the pipeline hollow and improving the heating effect and efficiency of the contact ring 22 on the ampoules.
[0050] A heating structure is provided on the outside of the contact ring 22 to heat it. The heating structure includes a heating coil 23, which corresponds one-to-one with the contact ring 22. The contact ring 22 is located directly below the heating coil 23, and the contact ring 22 and heating coil 23 are coaxially arranged. The heating coil 23 is connected to an electromagnetic induction heater 13, which is fixedly mounted on the support plate 10. The heating coils 23 can be connected in series or parallel with the electromagnetic induction heater 13 as needed. Parallel connection allows for targeted heating of ampoules of a specific size. When the heating coils 23 are connected in parallel, a switch is installed on the circuit of each heating coil 23. The switch and controller are electrically connected using existing technology as needed, thereby selecting the appropriate heating coil 23 to operate.
[0051] The contact ring 22 is made of steel pipe, which can be alloy steel pipe or stainless steel pipe. The heating coil 23 has a high heating efficiency for steel pipe, which can improve the heating effect on the ampoule cap. The water inlet branch pipe 18 and water outlet branch pipe 19 can be made of copper pipe as needed to reduce the heating effect of the heating coil 23 on the copper pipe.
[0052] The support plate 10 is provided with an elastic structure that presses the contact ring 22 onto the ampoule cap. The elastic structure includes a compression spring 24, which is sleeved on the outside of the inlet branch pipe 18 and the outlet branch pipe 19. Positioning plates are fixedly installed on both the inlet branch pipe 18 and the outlet branch pipe 19, and the two ends of the compression spring 24 are respectively fixed to the positioning plates and the upper limit plate 15. The upper limit plate 15 and the lower limit plate 16 are provided with through holes through which the inlet branch pipe 18 and the outlet branch pipe 19 pass, and the inlet branch pipe 18 and the outlet branch pipe 19 are slidably connected to the upper limit plate 15 and the lower limit plate 16. The upper limit plate 15 and the lower limit plate 16 are both fixed to the support plate 10. The inlet branch pipe 18 is connected to the main inlet pipe 17 via a telescopic pipe 21, and the outlet branch pipe 19 is connected to the main outlet pipe 20 via a telescopic pipe 21. The telescopic pipe 21 is a telescopic flexible hose or telescopic corrugated pipe, which meets the lifting and lowering needs of the outlet branch pipe 19 and the inlet branch pipe 18.
[0053] The housing 1 is equipped with a moving mechanism that drives the moving frame 3 to move within the housing 1. The moving mechanism drives the ampoule to move between the contact ring 22 and the fixed plate 6, thereby realizing the feeding, heating / cooling, separation and unloading of the ampoule.
[0054] like Figure 9-12 As shown. The moving mechanism includes a base plate 28, which is fixed to the bottom inner surface of the housing 1. A slide block 31 is slidably mounted on the base plate 28, and the slide block 31 has a threaded hole through which a lead screw 30 passes and is adapted to the lead screw 30. The lead screw 30 is rotatably connected to the base plate 28 via a bearing seat. A motor 29 is mounted on the base plate 28 to drive the lead screw 30 to rotate. The motor 29 is electrically connected to the controller using existing technology as needed. A guide rail 32 is mounted on the base plate 28 to guide the sliding of the slide block 31. A lifting plate 33 is fixedly mounted above the slide block 31. A telescopic hinge 34 is provided between the lifting plate 33 and the moving frame 3 to drive the lifting plate 33 to move up and down. The telescopic hinge 34 is an existing electric telescopic hinge 34, which realizes the lifting of the lifting plate 33. The electric telescopic hinge 34 is electrically connected to the controller using existing technology as needed.
[0055] The ampoule opening method based on the above ampoule opening device includes the following steps:
[0056] S1. Place the ampoule into the corresponding container 9 and press the corresponding button on the control panel 5. The motor 29 rotates under the action of the controller, and the motor 29 drives the lead screw 30 to rotate. The lead screw 30 drives the slide block 31 to slide along the lead screw 30 into the housing 1. The ampoule cap pushes the baffle 7 to rotate, and the ampoule passes through the slot of the fixing plate 6 through the baffle 7. The ampoule moves to directly below the contact ring 22, and the motor 29 stops moving.
[0057] S2. The telescopic hinge 34 is in operation. The telescopic hinge 34 drives the receiving box 9 and the ampoule to move upward through the moving frame 3. The cap of the ampoule is inserted into the contact ring 22. The ampoule pushes the contact ring 22 to move upward. The contact ring 22 drives the water inlet branch pipe 18 and the water outlet branch pipe 19 to move upward synchronously. The compression spring 24 is compressed, and the contact ring 22 is pressed against the outside of the ampoule cap.
[0058] S3. The electromagnetic induction heater 13 is activated, and the heating coil 23 rapidly heats the contact ring 22. The heated contact ring 22 then rapidly heats the ampoule cap through the contact surface. After heating is complete, the electromagnetic induction heater 13 stops working, and the switch is turned off.
[0059] S4. The first solenoid valve 26 opens, and the low-temperature chilled water in the refrigerator 12 enters the contact ring 22 through the main inlet pipe 17 and the branch inlet pipe 18. The contact ring 22 rapidly cools the contact surface. Based on the principle of thermal expansion and contraction and the effect of thermal stress, the ampoule cap breaks uniformly at the contact point with the contact ring 22. Subsequently, the low-temperature chilled water flows back into the refrigerator 12 through the branch outlet pipe 19 and the main outlet pipe 20. After cooling is completed, the first solenoid valve 26 and the refrigerator 12 close.
[0060] S5. The telescopic hinge 34 retracts, the ampoule moves downward, the ampoule separates from the contact ring 22, and the compression spring 24 returns to its original position. The motor 29 reverses, and the motor 29 drives the slide block 31 to slide outward along the lead screw 30 via the lead screw 30. The ampoule slides outward, and the ampoule cap contacts the baffle 7. The baffle 7 is restricted from swinging outward by the slotted top hinge. After the ampoule is rapidly heated and cooled and broken evenly, the ampoule cap falls into the collection frame 4 under the action of the baffle 7. The ampoule body moves to the pick-and-place area, ready for use.
[0061] S6. Air compressor 14 starts, second solenoid valve 27 opens, compressed air enters water inlet main pipe 17 through air inlet pipe 25, and the low-temperature chilled water in water inlet main pipe 17 flows back into refrigeration unit 12 through water inlet branch pipe 18, contact ring 22, water outlet branch pipe 19, and water outlet main pipe 20. Second solenoid valve 27 closes. Waiting for the next bottle opening operation.
[0062] Therefore, the ampoule opening device and method described in this invention can solve the problems of existing opening devices generating glass powder fragments, having complex structures, and low reliability during the opening process.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.

4. A method for opening an ampoule bottle based on the ampoule opening device according to claim 3, characterized in that: Includes the following steps: S1. Place the ampoule into the corresponding container, press the corresponding button on the control panel, the motor rotates under the action of the controller, the motor drives the lead screw to rotate, the lead screw drives the slide block to slide along the lead screw into the housing, the ampoule cap pushes the baffle to rotate, the ampoule passes through the baffle through the slot of the fixed plate, the ampoule moves to directly below the contact ring, and the motor stops moving. S2. The telescopic hinge is in operation. The telescopic hinge moves the container and ampoule upward through the moving frame. The ampoule cap is inserted into the contact ring. The ampoule pushes the contact ring upward. The contact ring drives the inlet branch pipe and outlet branch pipe to move upward synchronously. The compression spring is compressed and the contact ring is pressed against the outside of the ampoule cap. S3. The electromagnetic induction heater starts, and heats the contact ring through the heating coil. The heated contact ring then rapidly heats the ampoule through the contact surface. After heating is complete, the electromagnetic induction heater stops working. S4. The first solenoid valve opens, and the low-temperature chilled water in the refrigerator enters the contact ring through the main inlet pipe and the branch inlet pipe. The contact ring rapidly cools the contact surface. Based on the principle of thermal expansion and contraction and the effect of thermal stress, the ampoule cap breaks uniformly at the contact point with the contact ring. Subsequently, the low-temperature chilled water flows back into the refrigerator through the branch outlet pipe and the main outlet pipe. After cooling is completed, the first solenoid valve and the refrigerator are closed. S5. The telescopic hinge retracts, the ampoule moves downward, the ampoule separates from the contact ring, and the spring returns to its original position; the motor reverses, the motor drives the slide to slide outward along the lead screw, the ampoule slides outward, the ampoule cap contacts the baffle, the baffle is restricted by the slotted top hinge and cannot swing outward, the ampoule cap, after being rapidly heated and cooled and evenly broken, falls into the collection frame under the action of the baffle, and the ampoule body moves to the pick-and-place area, waiting to be used; S6. The air compressor starts, the second solenoid valve opens, and compressed air enters the water inlet main pipe through the air inlet pipe. The low-temperature cold water in the water inlet main pipe flows back into the refrigeration unit through the water inlet branch pipe, contact ring, water outlet branch pipe, and water outlet main pipe; waiting for the next bottle opening operation.
