[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples:

[0035] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0036] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0037] Example 1, combined with Figures 1 to 5 As shown, this embodiment provides a closed ampoule opening device, including a housing 1 and a cap 4 that engages with the housing 1. The housing 1 has sequentially formed an opening 13 for the ampoule head to enter, a cavity 14 for receiving the ampoule head, and a storage cavity 15 for storing the ampoule head. The storage cavity 15 is connected to the cap 4. A clamping member 3 is used to clamp the ampoule head. The clamping member 3 is movably disposed on the housing 1 corresponding to the position of the cavity 14. A cutting component 2 is movably mounted on the housing 1. The cutting component 2 includes a grinding wheel 27, which is positioned within the opening 13. The ampoule head enters the cavity 14 through the opening 13 and is adjacent to the storage cavity 15. Under external force, the cutting component 2 moves, causing the grinding wheel 27 to abut against the connection between the bottle body and the ampoule head. The bottle body and housing 1 rotate relative to each other, causing scratches to appear on the ampoule 5. The ampoule head and bottle body are then separated by bending the bottle body and housing 1. Because the housing 1 has a closed space, when the ampoule head enters the cavity 14, the connection between the ampoule head and the bottle body is located at the opening 13. This ensures that the sharp edges after separation during the opening of the ampoule 5 are contained within the opening 13, thus preventing medical personnel from directly contacting the sharp edges and causing injury.

[0038] In practical application, after the ampoule head enters the cavity 14 through the opening 13, the clamping member 3 clamps the ampoule head. The connection between the ampoule head and the bottle body (the connection between the ampoule head and the bottle body, which is the pre-cracked part 51) corresponds to the cutting member 2. The cutting member 2 is moved so that the grinding wheel 27 of the cutting member 2 abuts against the outer wall of the ampoule 5. The bottle body and the shell 1 are rotated relative to each other, so that the grinding wheel 27 cuts a scratch at the pre-cracked part 51. By bending the bottle body and the shell 1, the ampoule head and the bottle body are separated. The clamping member 3 is moved so that the ampoule head is released from the control of the clamping member 3. At this time, the shell 1 is still in the state of tilting upward through the opening 13. The ampoule head finally falls into the storage cavity 15. The shell cap 4 is opened later to process the ampoule head uniformly, thereby reducing contact with the external environment.

[0039] In this embodiment, the housing 1 and the cover 4 adopt an elastic buckle and slot design (not shown in the figure). The elastic buckle and slot engage to make the housing 1 and the cover 4 detachably connected. After the housing 1 and the cover 4 are assembled, their connection stability can be guaranteed. In addition, the housing 1 and the cover 4 can be made of medical transparent plastic material. The transparent plastic material helps medical personnel to observe the operating status of the ampoule 5.

[0040] Specifically, the first step is to achieve the clamping action of ampoule 5, combined with... Figure 4 , Figure 5 As shown, the clamping member 3 includes two opposing clamping parts, one of which is screwed to the housing 1, and the other clamping part is movably connected to the housing 1. The position of one of the clamping parts screwed to the housing 1 is adjusted according to the specifications of the ampoule head. Medical personnel control the movement of the other clamping part, causing it to move towards the ampoule head, and driving the ampoule head towards the clamping part (the clamping part screwed to the housing 1), where it abuts against the outer wall of the ampoule head, thus clamping the ampoule 5 between the two opposing clamping parts.

[0041] In this embodiment, the first clamping member 31 includes a first clamping part 314 and a first control rod 312 connected to the first clamping part 314. The housing 1 has a through hole 12 corresponding to the first control rod 312. The first control rod 312 is slidably connected in the through hole 12. The first control rod 312 is provided with a first control cap 311 for medical personnel to press with their fingers. The first control cap 311 is used to control the movement of the first control rod 312. The first control cap 311 is provided with a protrusion 315. The protrusion 315 helps to increase the friction with the medical personnel's fingers and prevent the medical personnel's fingers from slipping off the first control cap 311. The second clamping member 32 includes a second clamping part 324 and a second control rod 322 rotatably connected to the second clamping part 324. The housing 1 has a threaded hole corresponding to the second control rod 322. The outer wall of the second control rod 322 has an external thread that mates with the threaded hole so that the second control rod 322 is screwed to the housing 1. The second control rod 322 is provided with a second control cap 321 for controlling the movement of the second control rod 322.

[0042] In specific operation, the second clamping member 32 is adjusted according to the same batch of ampoules of the same specifications. The second control lever 322 is rotated to move the second clamping part 324. After the adjustment is completed, the medical staff presses the first control cap 311. The first control cap 311 drives the first control lever 312 to move, so that the first clamping part 314 and the second clamping part 324 clamp the ampoule head.

[0043] In this embodiment, the clamping part has a clamping surface 33, which is arc-shaped and conforms to the shape of the ampoule head. Both the first clamping part 314 and the second clamping part 324 have clamping surfaces 33. The arc-shaped design of the clamping surfaces 33 allows them to fit more closely to the outer wall of the ampoule head, enabling the clamping member 3 to clamp the ampoule more stably.

[0044] In this embodiment, an anti-slip layer is provided on the clamping surface 33. The anti-slip layer covers the surface of the clamping surface 33 and abuts against the outer wall of the ampoule head. The anti-slip layer is made of rubber. The rubber anti-slip layer can increase the friction with the ampoule head and enhance the clamping stability between the two, but does not affect the rotation of the ampoule head within the area enclosed by the first clamping part 314 and the second clamping part 324.

[0045] In this embodiment, a second elastic element is sleeved on the control rod, with its two ends abutting against the housing 1 and the clamping part, respectively. The second elastic element includes a second spring 313 and a third spring 323. The second spring 313 is sleeved on the first control rod 312, with its two ends connected to the housing 1 and the first clamping part 314, respectively. After the medical personnel release their fingers, the second spring 313 restores its elasticity, causing the first clamping part 314 to rebound, thereby realizing the automatic reset function of the first clamping part 314. The third spring 323 is sleeved on the second control rod 322, with its two ends connected to the housing 1 and the second clamping part 324, respectively. The third spring 323 helps to ensure the linear movement of the second clamping part 324 and improves the connection stability between the second clamping part 324 and the housing 1. The second clamping part 324 may also be provided with auxiliary rods. Two auxiliary rods are provided, one on the left end and the other on the right end of the second clamping part 324, and both slidingly connected to the housing 1, to ensure the linear reciprocating movement of the second clamping part 324.

[0046] Specifically, after the clamping member 3 clamps the ampoule head, the cutting member 2 further includes a connecting rod 22 and a sliding rod 23 sleeved on and screwed to the connecting rod 22. The sliding rod 23 is slidably disposed in the housing 1, and the grinding wheel 27 is disposed on the sliding rod 23. The end of the connecting rod 22 is provided with a rotating cap 21, which is used to control the movement of the connecting rod 22. The beginning end of the connecting rod 22 is provided with a connecting seat 26, and the grinding wheel 27 is disposed on the connecting seat 26. By rotating the rotating cap 21, the connecting rod 22 is driven to rotate, thereby driving the sliding rod 23 screwed to the connecting rod 22 to move along the hole in the housing 1, thereby driving the grinding wheel 27 on the connecting seat 26 to move towards the ampoule 5, relative to the rotation of the bottle and the housing 1, so that the pre-cracked part 51 is cut with scratches, thereby realizing the pre-cutting operation of the pre-cracked part 51 of the ampoule 5.

[0047] In this embodiment, the housing 1 has screw holes corresponding to the connecting rod 22 and the sliding rod 23, respectively. The screw holes are screwed to the connecting rod 22. The housing 1 has a sliding groove, and the sliding rod 23 has a slider 24 corresponding to the sliding groove. The slider 24 is slidably disposed in the sliding groove. The outer wall of the connecting rod 22 has an external thread that is screwed to the screw hole. By rotating the screw cap 21, the connecting rod 22 is rotated, thereby moving the connecting rod 22 along the hole direction of the screw hole. The sliding rod 23 is screwed to the connecting rod 22, and the slider 24 is slidably disposed in the sliding groove to restrict the rotation of the sliding rod 23 in the circumferential direction. This allows the sliding rod 23 to drive the grinding wheel 27 to move linearly, so that the cutting edge of the grinding wheel 27 always corresponds to the pre-scraping part 51, thereby realizing the pre-cutting and scratching operation of the pre-scraping part 51.

[0048] In this embodiment, a first elastic element is sleeved on the slide rod 23, and the two ends of the first elastic element abut against the grinding wheel 27 and the housing 1, respectively. The first elastic element is a first spring 25, and the two ends of the first spring 25 are connected to the connecting seat 26 and the housing 1, respectively. The first spring 25 uses its own elasticity to ensure the movement stability of the connecting seat 26.

[0049] In this embodiment, a protrusion 16 is provided in the storage cavity 15 near the cavity 14. The inner diameter of the protrusion 16 is larger than the outer diameter of the ampoule head, so as to facilitate the ampoule head after it is separated from the bottle to enter the storage cavity 15, and also to block the ampoule head from entering the storage cavity 15.

[0050] In this embodiment, the housing 1 is a rectangular structure with a recess 11 in the middle to make the rectangular structure fit the shape of the hand so as to better fit the hand and help medical personnel hold the housing 1 for operation.

[0051] The working principle of this utility model is as follows: During operation, medical personnel adjust the second clamping member 32 according to the same batch of ampoules of the same specifications. Specifically, rotating the second control lever 322 drives the second clamping part 324 to move. After moving to the appropriate position, the ampoule head enters the cavity 14 from the opening 13 and then enters the storage cavity 15. When the ampoule head enters the cavity 14, the pre-splitting part 51 is located at the opening 13. Then, by rotating the cap 21, the connecting rod 22 is rotated, which drives the slide rod 23 screwed to the connecting rod 22 to move along the hole of the housing 1, thereby driving the connecting seat. The grinding wheel 27 on 26 moves toward the ampoule 5, so that the grinding wheel 27 abuts against the pre-cracked part 51, and rotates the bottle and shell 1 relative to each other, so that the pre-cracked part 51 cuts a scratch, thereby realizing the pre-cutting operation of the pre-cracked part 51 of the ampoule 5. Then, by bending the bottle and shell 1, the ampoule head and the bottle are split. The split ampoule head enters the storage cavity 15 because the shell 1 is in an inclined state. This means that the sharp edge after splitting is sealed inside the shell 1 during the opening of the ampoule 5, thereby avoiding direct contact between medical personnel and the sharp edge, which could lead to injury.

[0052] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
