Abstract

To provide an ampoule opener which is easy to assemble and whose entire structure can be stabilized by joining parts without using fastening members such as bolts. [Solution] The ampoule opener (10) comprises a lid (20), a middle body member (30), a guide member, a body base member (50), and one or more elastic members. The first joining structure of the lid and the second joining structure of the middle body member combine to form a sandwiched space (70) between the middle body member and the lid. The guide member is inserted into a support plate inside the middle body member. The body base member is joined to the guide member by a third joining structure. One end of the elastic member abuts the bottom surface of the support plate of the middle body member, and the other end abuts the body base member. Thanks to the above-mentioned structural features, by inserting the top of the ampoule into the sandwiched space and applying force to the lid, the middle body member moves along the guide member from a first position (P1) to a second position (P2), clamping the top of the ampoule and easily cutting the neck of the ampoule.

Description

[Technical Field]

[0001] The present invention relates to an ampoule opener, and more particularly to an ampoule opener whose parts are joined together by a joint structure, making assembly easy and easy to use. [Background technology]

[0002] An ampule is a small, thin glass container for storing medicine that is sealed by melting the glass at high temperatures, allowing the medicine to be stored securely. To open an ampule, the user simply breaks the top off the ampule to separate it from the main body, allowing the medicine inside to be removed. However, because the ampule is made of a hard material, if the ampule is not opened properly, the user may injure their hand or fragments may get into the medicine, rendering it unusable.

[0003] Ampoule opening tools have been developed to create a safe medical environment and prevent users from getting injured when opening ampoules. Patent Document 1 (Patent Document 1) describes an ampoule opening device consisting of a first body and a second body connected by a rail. The body of the ampoule is placed within the first body, and the top is inserted into the second body. As the second body slides along the rail, the top of the ampoule is cut off by a cutting hole. However, Patent Document 1 limits the size of the ampoule; it can only accommodate ampoules whose necks are located at the joint between the first and second bodies. If the neck of the ampoule is not securely located at the joint between the first and second bodies, the ampoule will not only not break incompletely, but glass fragments may fall into the medicine inside.

[0004] In contrast, there are many other types of ampoule openers currently available on the market, but the more complex the structure, the higher the manufacturing cost. Therefore, the objective of this invention is to provide an ampoule opener that is easy to assemble and use. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Taiwan Utility Model Patent No. M652944 Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the shortcomings of current ampoule openers, the main purpose of this invention is to provide an ampoule opener that is easy to assemble and can stabilize the entire structure by joining parts without using fastening members such as bolts. [Means for solving the problem]

[0007] To solve the above-mentioned problems, the ampoule opener comprises a lid, a middle body member, a guide member, a body base member, and one or more elastic members. The lid has a first joining structure. The first joining structure is formed on the bottom edge of the lid. The middle body member has a second joining structure and a support plate. The second joining structure is formed on the top edge of the middle body member and joins with the first joining structure of the lid to form a space between the middle body member and the lid. The support plate is disposed inside the middle body member. The guide member is inserted into the support plate of the middle body member. The middle body member moves along the guide member between a first position and a second position. The body base member has a third joining structure. The third joining structure is formed on the inside of the body base member to join with the guide member. One end of the one or more elastic members abuts the bottom surface of the support plate of the middle body member, and another end abuts the body base member. When the middle body member is placed in the first position, the elastic members remain in a released state. The top surface of the support plate abuts the bottom surface of the guide member. When the middle main body member is placed in the second position, the cover approaches the guide member and the elastic member is compressed by the support plate of the middle main body member, thereby reducing the volume of the sandwiched space.

[0008] Specifically, the ampoule opener of the present invention has three connecting structures, namely, a first connecting structure, a second connecting structure, and a third connecting structure, which simplifies assembly and secures the parts without the need for additional fastening members, effectively reducing manufacturing costs. To open an ampoule, the top of the ampoule is pushed into the space between the ampoule opener and the middle member of the main body compresses the elastic member toward the base member, clamping and securing the top of the ampoule between the lid and the guide member. The neck of the ampoule can then be cut by rotating it around the axis, allowing for easy and safe opening of the ampoule. After opening the ampoule, and to dispose of the ampoule top held within the ampoule opener, the middle member of the main body moves from the second position to the first position due to the repulsive force of the elastic member, disposing of the ampoule top into the waste disposal bin. This reduces the force exerted on the lid and prevents injury from contact with the cut ampoule top.

[0009] In a more preferred embodiment, the lid has a first opening with an arc-shaped end, and the middle body member has a second opening with an arc-shaped end. The first and second openings are connected by a sandwiching space. The above-described structural features allow the necks of ampoules of different sizes to be easily cut by aligning them with the first and second openings, improving convenience during use.

[0010] In a more preferred embodiment, the support plate of the main body middle member has one or more axial holes. The guide member has one or more protruding shafts. The shafts pass through the axial holes and fit into the third joining structure of the main body base member. The elastic member is disposed over the shafts. With the above structural features, the main body base member and the guide member are fixed together. The main body middle member remains movable and can move along the shafts of the guide members.

[0011] In a more preferred embodiment, the support plate of the middle main body member further has two connecting holes, and the guide member has two protruding connecting rods. The connecting rods are inserted into the connecting holes. Due to the above-mentioned structural features, the connecting rods limit the movement path of the middle main body member and provide a guiding function, thereby preventing the middle main body member from shifting during movement.

[0012] In a more preferred embodiment, the middle body member has two guide blocks protruding from both sides of its inner periphery. The two guide blocks are mounted on the top surface of the support plate. The guide member has two recessed guide grooves recessed from both sides. The two guide blocks fit into the recessed guide grooves. Specifically, the present invention uses a connecting rod to limit the movement path of the middle body member, and the guide blocks and recessed guide grooves allow the middle body member to move along the guide members, ensuring linear movement of the middle body member between the first and second positions, thereby improving convenience when opening the container.

[0013] In a more preferred embodiment, the base member has a guide surface recessed into its outer periphery. When the middle member moves from the first position to the second position, it surrounds the guide surface and moves along the guide surface. Due to the above-described structural feature, the middle member compresses the elastic member toward the base member, and a portion of the middle member overlaps the base member when it is placed in the second position, thereby reducing the volume of the ampoule opener.

[0014] In a more preferred embodiment, the ampoule opener further includes a first cushion member and a second cushion member. The first cushion member and the second cushion member are disposed within the clamping space. The first cushion member is disposed on the inner surface of the lid. The second cushion member is disposed on the top surface of the guide member. Due to the above-described structural features, when the ampoule is clamped and secured, the lid and the guide member do not come into direct contact with the top of the ampoule, thereby preventing the top of the ampoule from bursting.

[0015] In a more preferred embodiment, the main body base member has a hanging ring, which is located at one end of the bottom of the main body base member. With the above-mentioned structural features, the user can hang the ampoule opener on clothes or a string by the hanging ring, and quickly take out the ampoule opener for use when needed.

[0016] In a more preferable case, the main body base member further includes a scraper, which is disposed at one end of the bottom of the main body base member. Because medical institutions need to check patients' prescriptions using a large number of labels, the scraper can be used to peel off the labels and quickly stick them in the designated position, improving work efficiency.

[0017] The detailed structure, features, assembly and usage of the ampoule opener of the present invention will be made clear through the following detailed description of the embodiments. It should be understood by those skilled in the art that the following detailed description and the embodiments presented by the present invention are merely examples for explaining the present invention and cannot limit the scope of the claims of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The ampoule opener of the present invention will now be described with reference to the drawings. In the specification, the same reference numerals in the drawings indicate the same or similar components or structural features. To clarify the technical features of the present invention, the proportions of the drawings presented in the embodiments may not coincide with the actual proportions. The features of each embodiment are not limited to one-sided arrangements and may be mutually applied. The arrangement of one component on another component is not limited to direct arrangement, but may also be indirect arrangement. In other words, the indirect arrangement of one component on another component involves placing one or more components between the two components. The direct arrangement of one component on another component involves placing nothing between the two components.

[0020] (One embodiment) 1 to 3, an ampoule opener 10 according to an embodiment of the present invention includes a cap 20, a main body middle member 30, a guide member 40, a main body base member 50, and one or more elastic members 60. The number of elastic members 60 is not particularly limited, and only one is required to perform the function of cutting the ampoule. This embodiment employs two elastic members 60 to improve stability during use.

[0021] The lid 20 has a first connecting structure 21 and a first opening 22. The first connecting structure 21 is formed on the bottom side edge of the lid 20 and has one or more protrusions on the inner peripheral surface of the lid 20. The first opening 22 is formed on one end of the lid 20 and has an arc shape.

[0022] The middle main body member 30 has a second connecting structure 31, a support plate 32, and a second opening 33. The second connecting structure 31 is formed on the top side of the middle main body member 30 and has one or more hooks on the inner peripheral surface of the middle main body member 30. The second connecting structure 31 connects with the first connecting structure 21 of the cover 20 to connect the middle main body member 30 and the cover 20. The support plate 32 is disposed inside the middle main body member 30 and connects the four walls of the middle main body member 30. It has two axial holes 321 and two connecting holes 322. The two axial holes 321 and two connecting holes 322 penetrate the top and bottom surfaces of the support plate 32. The support plate 32 further has an annular wall 323. The annular wall 323 protrudes from the bottom surface of the support plate 32 around the axial hole 321 and the connecting hole 322. The second opening 33 is formed at one end of the middle main body member 30 and is arc-shaped. When the lid 20 is placed over the intermediate body member 30, a sandwiching space 70 is formed between the lid 20 and the intermediate body member 30. The first opening 22 and the second opening 33 correspond to each other.

[0023] The guide member 40 is composed of a plate member and is disposed in the space 70 between the cover 20 and the support plate 32 of the middle body member 30. It has two shafts 41 and two connecting rods 42 protruding from its bottom surface. The two shafts 41 are inserted into the axial holes 321 of the middle body member 30, respectively. The two connecting rods 42 are inserted into the connecting holes 322 of the middle body member 30, respectively. Thanks to the above-described structural features, the middle body member 30 can move between the first position P1 and the second position P2 along the guide member 40. To suppress vibration of the middle body member 30 during movement, the guide member 40 has two recessed guide grooves 43 formed on both sides. The middle body member 30 has two guide blocks 34 corresponding to the recessed guide grooves 43. The guide blocks 34 are formed on both sides of the inner circumferential surface of the middle body member 30 and on the top surface of the support plate 32, and their ends are connected to the second connecting structure 31. The two guide blocks 34 are respectively housed in the guide grooves. Due to the above-described structural features, the moving intermediate body member 30 moves along the connecting rod 42 of the guide member 40 and the guide grooves 43, allowing for smooth and linear movement between the first position P1 and the second position P2, improving user convenience.

[0024] The main body base member 50 has a bottom plate 51 and a third connecting structure 52. The third connecting structure 52 is formed on the inner bottom of the main body base member 50. The bottom plate 51 fits into the inside of the third connecting structure 52 from below the main body base member 50. The third connecting structure 52 is a circular hole. The two shafts 41 of the guide member 40 pass through axial holes 321 in the middle main body member 30 and are fixed within the third connecting structure 52, connecting the guide member 40 and the main body base member 50. The main body base member 50 further has a guide surface 53 formed as a recess on its outer periphery. The guide surface 53 is surrounded by the inner periphery of the bottom of the middle main body member 30.

[0025] The main body base member 50 has a hanging ring 54 at one end of the bottom and a scraper 55 at the other end of the bottom. The hanging ring 54 allows the ampoule opener 10 to be hung on clothing or a string, and the ampoule opener 10 can be quickly removed and used when needed. The scraper 55 allows the label to be peeled off and quickly attached to the specified location, improving work efficiency.

[0026] The two elastic members 60 are made up of springs and are respectively disposed over the two shafts 41 of the guide member 40. One end of each elastic member 60 abuts against the annular wall 323 of the shaft hole 321 of the support plate 32 of the main body intermediate member 30, and the other end abuts against the inner bottom of the main body base member 50.

[0027] As shown in Figures 4 to 7, when opening ampoule 80, the top of ampoule 80 is inserted into sandwiching space 70 through first opening 22 and second opening 33, and the neck of ampoule 80 is aligned with first opening 22 and second opening 33, thereby maintaining the top of ampoule 80 between lid 20 and guide member 40. In this invention, to prevent lid 20 and guide member 40 from hitting the top of ampoule 80 and causing it to burst, lid 20 further has a first cushion member 90 on its inner surface. Guide member 40 further has a second cushion member 91 on its top surface. The top of ampoule 80 is positioned between first cushion member 90 and second cushion member 91. The above-mentioned structural features reduce the risk of ampoule 80 bursting due to impact or careless use.

[0028] Next, if a force is applied to the lid 20 while holding the lid 20 and the main body base member 50 with one hand, the middle main body member 30 moves along the connecting rod 42 and the concave guide groove 43 of the guide member 40, moving the lid 20 toward the guide member 40. The support plate 32 of the middle main body member 30 moves toward the main body base member 50, moving the middle main body member 30 from the first position P1 to the second position P2. During the movement, the elastic member 60 is compressed by the annular wall 323 of the support plate 32, contracting with one end abutting the main body base member 50 as a fulcrum, and increasing the width of the guide surface 53 of the main body base member 50 surrounded by the middle main body member 30. Because the guide member 40 and the main body base member 50 are fixed together and their positions do not change, the volume of the sandwiched space 70 gradually decreases as the lid 20 moves toward the guide member 40. After the top of the ampoule 80 is sandwiched and fixed between the first cushion member 90 and the second cushion member 91, the neck of the ampoule 80 can be easily cut by turning the ampoule opener 10 around the neck of the ampoule 80 as an axis, and the ampoule 80 can be separated into two parts, the top and the body, and the medicine inside can be taken out.

[0029] After opening the ampoule 80, when the top trapped inside the ampoule opener 10 is to be removed, the force on the lid 20 is released, releasing the elasticity of the elastic member 60. As the middle body member 30 moves from the second position P2 to the first position P1, the lid 20 gradually separates from the guide member 40, bringing the top surface of the support plate 32 of the middle body member 30 closer to the bottom surface of the guide member 40. When the top surface of the support plate 32 of the middle body member 30 then abuts against the bottom surface of the guide member 40, the middle body member 30 is no longer able to move, and the first cushion member 90 and the second cushion member 91 maintain a state in which the top of the ampoule 80 is released. This prevents the top of the ampoule 80 from dropping into a waste disposal bin and causing injury to a hand that comes into contact with the cut edge of the top of the ampoule 80.

[0030] The ampoule opener 10 of the present invention has the following advantages over the prior art.

[0031] 1. Compared to conventional ampoule opening devices, which have a relatively complex structure and a relatively large volume, the present invention assembles the lid 20, the main body middle member 30, the guide member 40, and the main body base member 50 of the ampoule opening device 10 using a joint structure without using fastening members such as bolts, thereby simplifying the assembly work and reducing manufacturing costs.

[0032] 2. In the present invention, the guide member 40 is inserted into the support plate 32 of the middle body member 30 to fix the guide member 40 and the support plate 32 together, and then the guide member 40 and the body base member 50 are joined together, i.e., the middle body member 30 and the body base member 50 are joined together via the guide member 40. Due to the above-mentioned structural features, the middle body member 30 can be moved toward the guide member 40 to adjust the volume of the clamping space 70, which not only allows the clamping of the ampoule 80 but also allows the neck of the ampoule 80 to be easily and safely cut off.

[0033] As described above, the present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the spirit of the invention. [Explanation of symbols]
