[0021] Compared with the prior art, implementing the embodiments of the present invention has the following beneficial effects:

[0022] The method of using the vial opener of this invention is as follows: When opening a vial with a pure aluminum cap, which has a single-layer structure and is relatively thick, the medical staff engages the first support plate in the slot of the second handle away from the arc-shaped plate. At this time, the distance between the arc-shaped plate and the first connecting plate is relatively large. Simultaneously, the arc-shaped plate can be engaged with the bottom of the thicker pure aluminum cap while the pressing plate is pressing down on it. When opening a vial with an aluminum-plastic cap, which has a double-layer structure of aluminum and plastic, with the plastic cap being thinner, the medical staff engages the first support plate in the slot of the second handle near the arc-shaped plate. At this time, the distance between the arc-shaped plate and the first connecting plate is relatively small. Simultaneously, the arc-shaped plate can be engaged with the bottom of the thinner plastic cap while the pressing plate is pressing down on it. Then, by gripping and rotating the first handle, the arc-shaped plate lifts the pure aluminum or plastic cap. Furthermore, rotating the second handle to clamp the pure aluminum or plastic cap with the arc-shaped plate prevents the cap from flying off during opening. Attached Figure Description

[0044] Reference Figures 1 to 7 This embodiment provides a method for using a vial opener. The vial opener 100 includes an opening component 1, a pressing component 2, a adjusting component 3, and a first handle 4. The pressing component 2 includes a first connecting plate 21 and a pressing plate 22 obliquely connected to the first connecting plate 21. The opening component 1 includes a second connecting plate 11 and an arc-shaped plate 12. One end of the second connecting plate 11 is hinged to the first connecting plate 21, and the other end is connected to the arc-shaped plate 12. One end of the first handle 4 is fixedly connected to the end of the first connecting plate 21 away from the pressing plate 22. The adjusting component 3 includes a first torsion spring 31, a first support plate 32, and a second handle 33. The second handle 33 has at least two slots 331 on the side near the pressing plate 22. One end of the second handle 33 is fixedly connected to the end of the second connecting plate 11 away from the arc-shaped plate 12. One end of the first support plate 32 is hinged to the first connecting plate 21 or the pressing plate 22 via the first torsion spring 31, and the other end is engaged in a slot 331. Specifically, in this embodiment, there are four slots, which allows the vial opener 100 to be used for vial caps of different sizes, as well as for opening other bottle caps such as those for oral liquids.

[0045] The above-mentioned vial opener 100 has two usage methods: opening pure aluminum vials and opening aluminum-plastic vials.

[0046] Opening a pure aluminum vial involves: rotating the second handle 33, resetting the first support plate 32 under the action of the torsion spring 31, resetting the second handle 33 so that the first support plate 32 is engaged in the slot 331 of the second handle 33 away from the arc plate 12, attaching the pressing plate 22 to the upper surface of the pure aluminum cap, abutting the arc plate 12 to the bottom of the pure aluminum cap, gripping the first handle 4 and rotating the first handle 4 to pry up the pure aluminum cap through the arc plate 12, then rotating the second handle 33 to drive the arc plate 12 to rotate so that the arc plate 12 and the pressing plate 22 work together to clamp the pure aluminum cap and prevent the pure aluminum cap from flying out;

[0047] Opening the aluminum-plastic vial involves rotating the second handle 33 and the first support plate 32, causing the first support plate 32 to engage with the slot 331 of the second handle 33 near the arc plate 12, bringing the pressing plate 22 into contact with the upper surface of the plastic cap, and bringing the arc plate 12 into contact with the bottom of the plastic cap. The first handle 4 is then gripped and rotated, causing the plastic cap to be lifted by the arc plate 12. The second handle 33 is then rotated, causing the arc plate 12 to rotate, so that the arc plate 12 and the pressing plate 22 work together to clamp the plastic cap, preventing it from flying out.

[0048] When opening a pure aluminum cap vial, the pure aluminum cap is a single-layer structure and relatively thick. Medical personnel engage the first support plate 32 in the slot 331 of the second handle 33, away from the arc-shaped plate 12. At this time, the distance between the arc-shaped plate 12 and the first connecting plate 21 is relatively large. Simultaneously, the arc-shaped plate 12 can be engaged with the bottom of the thicker pure aluminum cap while the pressing plate is pressing down on it. When opening an aluminum-plastic cap vial, the aluminum-plastic cap has a double-layer structure of aluminum and plastic, with the plastic cap being thinner. Medical personnel engage the first support plate 32 in the slot 331 of the second handle 33, near the arc-shaped plate 12. At this time, the distance between the arc-shaped plate 12 and the first connecting plate 21 is relatively small. Simultaneously, the arc-shaped plate 12 can be engaged with the bottom of the thinner plastic cap while the pressing plate 22 is pressing down on it. By gripping and rotating the first handle 4, the arc-shaped plate 12 lifts up either the pure aluminum cap or the plastic cap. In addition, turning the second handle 33 to clamp the pure aluminum cover or plastic cover through the arc plate 12 can prevent the pure aluminum cover or plastic cover from flying out when opening.

[0049] Better, refer to Figures 1 to 4In this embodiment, the gear shifting assembly 3 further includes a first spring 34. The first handle 4 has a first opening slot 41 for receiving the second handle 33. One end of the first spring 34 is connected to the second handle 33, and the other end is connected to the inner wall of the first opening slot 41. In use, the operator holds the first handle 4 and pulls the first support plate 32 to rotate. The first support plate 32 pushes the second handle 33 and drives the arc plate 12 to rotate, thereby changing the gear shift and changing the angle of the arc plate 12. At the same time as shifting gears, the first spring 34 is compressed. When it is necessary to return to the gear position, the medical staff can move the second handle 33 to separate the second handle 33 from the first support plate 32. Under the action of the first spring 34, the first support plate 32 returns to the position corresponding to the slot 331 farthest from the arc plate 12, thereby achieving quick reset.

[0050] Better, refer to Figures 1 to 5 In this embodiment, the second handle 33 is provided with several numbered sections 332, each corresponding to a specific slot 331. In practical applications, vials come in various sizes and heights. By adjusting the angle of the arc-shaped plate 12 according to the different slots 331 into which the first support plate 32 engages, the applicable size of the multi-functional vial opener 100 can be adjusted, and this is marked by the numbered sections 332. The operator can quickly select the desired slot 331 by matching the size of the required vial with the markings on the numbered sections 332, and then rotate the first support plate 32 to insert it into the slot 331, thereby switching to the desired position.

[0051] Better, refer to Figure 5 and Figure 6 In this embodiment, the vial opener 100 also includes a needle removal assembly 5. The needle removal assembly 5 includes a third connecting plate 51 with a clamp-shaped part. The end of the third connecting plate 51 away from the clamp-shaped part is connected to the pressing plate 22. Between the step of lifting the bottle cap and the step of resetting, there is also a step of using the vial. The use of the vial includes drawing the medicine in the vial with a syringe and then pulling out the syringe through the clamp-shaped part.

[0052] In practical applications, after the vial is used up, medical staff still need to remove the used syringe needle. To do this, they can quickly pull out the needle by clamping it with forceps. Using a single tool for rapid vial opening and needle removal improves the efficiency of medical staff, saving them time and preventing injury during manual needle removal.

[0053] Better, refer to Figures 5 to 7In this embodiment, the vial opener 100 further includes a pen-cutting assembly 6. The pen-cutting assembly 6 includes a locking member 61, a pen-cutting body 62, and a second spring 63. The pressing plate 22 has a first blind hole. The pen-cutting body 62 is inserted into the first blind hole. One end of the second spring 63 abuts against the end of the pen-cutting body 62 away from the sharp part, and the other end abuts against the inner wall of the first blind hole. The locking member 61 has a first through hole 611 and a first threaded part that is threadedly connected to the first blind hole. The pen-cutting body 62 passes through the first through hole 611. The diameter of the first through hole 611 gradually decreases from the side closer to the first blind hole to the side farther away from the first blind hole, and the outer wall of the sharp part of the pen-cutting body 62 fits against the inner wall of the first blind hole. In practical applications, medical personnel may encounter situations where they need to pierce specific items with a tool. In such cases, by rotating the locking member 61, the pen body 62 can be extended under the action of the second spring 63, allowing the piercing operation to be performed through the pen body 62. After use, by rotating the locking member 61, the pen body 62 is pushed to compress the second spring 63, thus allowing the pen body 62 to be stored inside the first blind hole and the first through hole 611.

[0054] Specifically, in this embodiment, the cutting pen body 62 is made of diamond. In practical applications, in addition to conventional pure aluminum cap vials and aluminum-plastic cap vials, medical staff also use glass ampoules during their work. Due to uncertainties in the manufacturing of ampoules, such as different wall thicknesses and varying cutting marks at the neck after processing (some have no cutting marks, while others have insufficient depth), they are easily broken when broken, causing injury and environmental pollution. Medical staff can use the cutting pen body 62 to cut glass ampoules for use, avoiding the adverse effects of broken bottles, injuries, glass shards scattered everywhere, and environmental impact during use.

[0055] Better, refer to Figure 1 In this embodiment, the vial opener 100 also includes a third handle 7, with the first handle 4 extending vertically and the third handle 7 extending horizontally. Depending on the actual usage, medical personnel can select either the first handle 4 or the third handle 7 to apply the multifunctional vial opener 100 to suitable opening scenarios. Specifically, refer to... Figure 5 In this embodiment, the second handle 33 and / or the third handle 7 are provided with a plurality of second through holes 71. By breaking the glass ampoule through the second through holes 71, it is possible to prevent injury to the hands of personnel during the breaking process.

[0056] Better, refer to Figure 5 In this embodiment, the first handle 4 has a threading hole 42. Medical personnel can carry it by threading a binding thread through the threading hole 42.

[0057] Better, refer to Figure 6 In this embodiment, the pressing component 2 further includes a toothed pressure surface 23, which is disposed on the side of the pressing plate 22 near the arc-shaped plate 12. During the process of the pressing component 2 pressing the bottle cap or fitting with the bottle cap, the toothed pressure surface 23 can increase the friction between the multifunctional vial opener 100 and the pressing component 2, thus preventing slippage during use.

[0058] This embodiment provides a method for using a vial opener 100. When it is necessary to open a vial with a pure aluminum cap, the pure aluminum cap has a single-layer structure and is relatively thick. Medical personnel engage the first support plate 32 with the slot 331 of the second handle 33, which is away from the arc-shaped plate 12. At this time, the distance between the arc-shaped plate 12 and the first connecting plate 21 is relatively large. At this time, the arc-shaped plate 12 can be engaged with the bottom of the relatively thick pure aluminum cap while the pressing plate is pressing the pure aluminum cap. Then, by gripping the first handle 4 and rotating the first handle 4, the arc-shaped plate 12 lifts up the pure aluminum cap or plastic cap.

[0059] When opening an aluminum-plastic cap vial, the vial has a double-layer structure consisting of an aluminum cap and a plastic cap, with the plastic cap being thinner. Medical personnel engage the first support plate 32 with the slot 331 of the second handle 33 near the curved plate 12. At this point, the distance between the curved plate 12 and the first connecting plate 21 is small. Simultaneously, while the pressing plate 22 presses down on the plastic cap, the curved plate 12 is engaged with the bottom of the thinner plastic cap. Then, by gripping and rotating the first handle 4, the curved plate 12 lifts up either the pure aluminum cap or the plastic cap.

[0060] Clamping: After opening the vial cap through the arc plate 12, turn the second handle 33 to clamp the pure aluminum cap or plastic cap through the arc plate 12, which can prevent the pure aluminum cap or plastic cap from flying out when opening.

[0061] When it is necessary to remove the needle, medical staff can quickly pull it out by clamping the needle tip with forceps.

[0062] When it is necessary to open the glass ampoule, the locking member 61 can be rotated to extend the cutting pen body 62 under the action of the second spring 63. The cutting pen body 62 can then cut the glass ampoule, allowing medical personnel to break and open it through the second through hole 71. After use, rotating the locking member 61 pushes the cutting pen body 62 to compress the second spring 63, thus retracting the cutting pen body 62 into the first blind hole and the first through hole 611.

[0063] The method of using the vial opener 100 in this embodiment has the following beneficial effects:

[0064] 1. When opening a vial with a pure aluminum cap, the cap is a single-layer structure and relatively thick. Medical personnel engage the first support plate 32 with the slot 331 of the second handle 33, away from the arc-shaped plate 12. At this time, the distance between the arc-shaped plate 12 and the first connecting plate 21 is relatively large. Simultaneously, while pressing the pure aluminum cap with the pressing plate, the arc-shaped plate 12 can be engaged with the bottom of the thicker cap. Then, by gripping and rotating the first handle 4, the arc-shaped plate 12 lifts the pure aluminum or plastic cap. Furthermore, by clamping the pure aluminum or plastic cap with the arc-shaped plate 12, it prevents the cap from flying off during opening.

[0065] 2. When it is necessary to open the aluminum-plastic cap vial, the aluminum-plastic cap has a double-layer structure of aluminum and plastic, with the plastic cap being thinner. Medical staff engage the first support plate 32 with the slot 331 of the second handle 33 near the arc-shaped plate 12. At this time, the distance between the arc-shaped plate 12 and the first connecting plate 21 is small. Simultaneously, the arc-shaped plate 12 can be engaged with the bottom of the thinner plastic cap while the pressing plate 22 presses down on the plastic cap. Then, by gripping and rotating the first handle 4, the arc-shaped plate 12 lifts up either the pure aluminum cap or the plastic cap.

[0066] Thirdly, in practical applications, after the vial is used up, medical staff still need to remove the used syringe needle. When this is necessary, medical staff can quickly remove the needle by clamping it with forceps. Using a single tool for rapid vial opening and needle removal improves the efficiency of medical staff, saves them time, and avoids potential injury to medical staff during manual needle removal.

[0067] Fourth, in practical applications, medical personnel may encounter situations where they need to use tools to pierce specific items. In such cases, by rotating the locking member 61, the pen body 62 can be extended under the action of the second spring 63, allowing the piercing operation to be performed through the pen body 62. After use, by rotating the locking member 61, the pen body 62 is pushed to compress the second spring 63, thus allowing the pen body 62 to be stored inside the first blind hole and the first through hole 611.

[0068] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
