Description

Technical Field

[0001] This utility model relates to the field of medical care tools, specifically to a medical bottle opener. Background Technology

[0002] In the process of dispensing medications in clinical settings, medical staff often need to handle a variety of drug packaging: for ampoules, they need to first scratch them with a grinding wheel and then pry them open by hand or by knocking them open; for aluminum bottle caps and plastic bottle caps, they need to use tools such as scissors and hemostatic forceps to open them, which is cumbersome and poses a risk of accidental injury from instruments.

[0003] The known patent publication number CN202558594U discloses a medical multifunctional bottle opener, which is equipped with a handle, body, capping groove, punching fork, percussion hammer, bottle cap hook, grinding wheel, medicine bottle opening pull ring hook, scale, ampoule folding hole, pupil size comparison hole, pen refill groove, etc. Although this design realizes the opening of the ampoule through the combination of grinding wheel and ampoule folding hole, different specifications of ampoule folding holes need to be preset. During operation, the size needs to be checked separately. Medical staff must insert the ampoule into the matching hole before it can be broken, which increases the complexity of the procedure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a medical bottle opener.

[0005] The technical solution of this utility model: A medical bottle opener includes a handle with a first circular block and a second circular block at each end. The lower part of the first circular block has a grinding wheel, the upper part of the first circular block has a hollow structure, the lower part of the first circular block has a lower arc groove on its inclined surface, the hollow structure has an upper pressing block inside, the upper pressing block has an upper arc groove that cooperates with the lower arc groove to clamp the ampoule, one end of a connecting rod is connected to the upper pressing block, and the other end passes through the hole of the first circular block and has a pressing block. The second round block has indentations on both the front and rear sides of the side away from the handle, forming a thin sheet-like needle removal pry bar in the middle, with a pry bar groove on the needle removal pry bar. The upper side of the second circular block is provided with an opening groove, and a bottle cap hook is provided at the opening of the opening groove near the handle side.

[0006] Furthermore, guide posts are provided on both sides of the lower arc groove. The guide posts pass through the through hole of the upper pressure block and are locked by the first nut. A spring is sleeved on the guide post. One end of the spring abuts against the inclined surface of the lower part of the first circular block, and the other end abuts against the upper pressure block.

[0007] Furthermore, a grinding wheel mounting groove is provided in the middle of the outer circumference of the lower oblique part of the first circular block, and the grinding wheel is installed in the grinding wheel mounting groove by screws and a second nut.

[0008] The beneficial effects of this utility model are: The first circular block of this utility model features a hollowed-out structure in its upper sloping portion, with an upper pressing block containing an upper arc-shaped groove inside. This upper pressing block, in conjunction with the lower arc-shaped groove in the lower sloping portion, forms a clamping mechanism. The synergistic effect of the upper and lower arc-shaped grooves achieves stable clamping of the ampoule. This structure's ergonomic tilt design allows the thumb to naturally position and press the block when gripping the handle, optimizing the force application angle, improving operational comfort, and enhancing clamping efficiency through mechanical transmission. Compared to CN202558594U, it eliminates the need for multi-specification ampoule folding holes, saving the size matching process, simplifying the operation, and reducing the risk of misoperation.

Detailed Implementation

[0010] The present invention can be further described through the following embodiments; however, the scope of the present invention is not limited to the following embodiments. It should be understood that the embodiments described herein are disclosed by way of illustration only, and the present invention is not intended to limit its scope to the details of the construction and arrangement of the components described below or illustrated in the figures. Furthermore, in describing preferred embodiments, specific terminology will be used for clarity. It should be understood that each specific term includes all technical equivalents that operate in a similar manner to achieve a similar purpose.

[0011] Example 1: Please refer to Figures 1 to 4 As shown, the device includes a handle 1, with a first circular block 2 and a second circular block 3 at each end. The lower part of the first circular block 2 is equipped with a grinding wheel 14. The upper part of the first circular block 2 has a hollow structure, and the lower part of the first circular block 2 has a lower arc groove 81 on its inclined surface. The hollow structure has an upper pressing block 5 inside, and the upper pressing block 5 has an upper arc groove 51 that cooperates with the lower arc groove 81 to clamp the ampoule. One end of the connecting rod 15 is connected to the upper pressing block 5, and the other end passes through the through hole of the first circular block 2 and has a pressing block 6. By pressing the pressing block 6, the upper pressing block 5 can be moved to clamp the ampoule. The inclined clamping design inside the first circular block 2 makes it convenient to press the pressing block 6 with the thumb when holding the handle 1, which makes it easier to apply force through the pressing block 6, thus improving the comfort and efficiency of the clamping operation. The second round block 3 has indented front and rear sides on the side away from the handle 1, forming a thin sheet-like needle removal pry bar 9 in the middle, with a pry bar groove 10 on the needle removal pry bar 9. The upper side of the second circular block 3 is provided with an opening and closing groove 11. The opening and closing groove 11 is provided with a bottle cap hook 4 near the opening on the side of the handle 1. By setting the opening and closing groove 11 in conjunction with the bottle cap hook 4, the opening operation of aluminum bottle caps and plastic bottle caps can be achieved quickly and stably.
