Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a medicine bag opening device and an atomizer. Background Technology

[0002] In existing technology, nebulizers atomize their internal medication into tiny particles, which are then expelled through the mist outlet. Nebulizers can be used for nebulized treatment of respiratory diseases. Before nebulization, the user needs to open the medication bag and pour the medication into the nebulizer. The inventors discovered that during this process, medication contamination or spillage can easily occur; or, for specially designed medication bags, specialized cutting tools are required, making the nebulizer inconvenient to use.

[0003] For example, the nebulizers disclosed in the invention patent application (application number: 202011232821X; application date: 2020-11-06) and the utility model patent (application number: 2021207245147; application date: 2021-04-09) all adopt an nebulizer cup design. First, the medicine bag is placed in the nebulizer cup, and then the medicine bag is opened by rotating the nebulizer cup. This method is only suitable for compressor-type nebulizers. Due to the limitations of the compressor-type nebulizer principle, the volume of the nebulizer cup cannot be reduced, and because the medicine bag is built into the nebulizer cup... The method of opening by rotation requires a certain amount of torque from the user when twisting the nebulizer cup. This can also lead to difficulties in determining whether the jamming is due to cutting or other reasons when the cup gets stuck during rotation, making it inconvenient to use. The nebulizer disclosed in the invention patent application (application number: 2021100950786; application date: 2021-01-25) is suitable for vibrating nebulizers. However, due to the limitation of the opening method, the medicine bag needs to be opened outside the nebulizer first. During the process of the user opening the medicine bag and pouring the medicine into the nebulizer, problems such as medicine contamination or medicine splashing are likely to occur.

[0004] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0005] To address at least one of the above-mentioned problems or other similar issues, embodiments of the present invention provide a medicine bag opening device and an atomizer that can conveniently and reliably open medicine bags.

[0006] According to one aspect of the present invention, a medicine bag opening device is provided, which is applicable to medicine bags that at least include a medicine sac portion, a liquid dispensing portion, and a sealing portion. The medicine bag opening device includes:

[0007] The main body has a receiving portion for accommodating the medicine bag;

[0008] The door is located on one side of the main body of the medicine bag opening device and has a mounting part for installing the medicine bag;

[0009] The medicine bag opening part has a cutting blade, which is located inside the main body, directly opposite the liquid outlet of the medicine bag when the door is closed, and can cut it;

[0010] The medicine compartment is located on the lower side of the main body, and its inlet end is located on the lower side of the opening part of the medicine bag. When the medicine bag is opened, the medicine flows out from the outlet part and into the medicine compartment.

[0011] Furthermore, the cutting blade has two parts, left and right, with its blades located on opposite sides of the two parts. The distance between the blades of the cutting blade gradually narrows from the door towards the main body. When the door is closed, the liquid outlet can be cut by the two parts of the cutting blade.

[0012] Furthermore, the left and right portions of the cutting blade are of different sizes, and / or the central axis at the narrowest distance between the blades is located on one side of the plane of motion of the central axis of the liquid outlet during the closing of the compartment door.

[0013] Furthermore, the opening part of the medicine bag is also provided with a thrust stop, which is located inside the main body and below the cutting blade, directly opposite the sealing part of the medicine bag when the compartment door is closed. During the closing process of the compartment door, when the thrust stop contacts the sealing part, the compartment door is not completely closed.

[0014] Furthermore, one end of the compartment door is connected to one end of the main body via a pivot or hinge. When the compartment door is opened or closed, it rotates around the pivot to move away from or towards the main body.

[0015] Furthermore, one end of the compartment door is connected to one end of the main body via a guide rail. When the compartment door is opened or closed, the plane on which the compartment door is located is parallel to or close to the plane on which the main body is located.

[0016] Furthermore, the mounting part includes a buckle. When the medicine bag is installed on the door, the buckle can engage the liquid outlet on the door. When the door is closed, the buckle is located above the cutting blade.

[0017] Furthermore, the mounting portion includes a receiving cavity that can accommodate at least a portion of the medicine bag and secure the medicine bag to the compartment door.

[0018] Furthermore, a pressing part is provided on the other side of the compartment door opposite to the main body. When the medicine bag is placed inside the mounting part, the pressing part is opposite to the medicine bag part.

[0019] The beneficial effects of the embodiments of the present invention are at least as follows:

[0020] 1. By setting up a medicine bag opening device and installing a cutting blade in the opening device, the medicine bag can be cut while the chamber door is closed after the medicine bag is installed, so that the medicine liquid can directly enter the medicine chamber. This not only makes it convenient and reliable to open the medicine bag installed in the nebulizer cup / nebulizer, but also effectively avoids medicine liquid contamination or spillage caused by opening the medicine bag outside the nebulizer cup / nebulizer.

[0021] 2. The cutting blade is equipped with two blades, left and right, and the distance between the two blades gradually narrows. During the closing process of the compartment door, the blades can gradually cut the liquid outlet from both sides, achieving uniform cutting force and avoiding the situation where women with less hand strength do not have enough force when opening the medicine bag.

[0022] 3. By setting two cutting blades of different sizes, the two blades can cut the liquid outlet section in a staggered manner, preventing the blades from blocking the liquid outlet section after cutting it and causing poor liquid flow.

[0023] 4. By setting a thrust stop inside the main body, the thrust stop restricts the movement trajectory of the sealing part during the opening of the medicine bag. Combined with the action of the cutting blade to cut the liquid outlet part, the liquid outlet part can be cut open more quickly, thus opening the medicine bag. At the same time, it can also effectively prevent the sealing part from blocking the liquid outlet part after it is cut open, thus preventing poor liquid flow.

[0024] 5. The opening and closing mechanism of the compartment door opening device and the main body is set to rotate. The distance between the cutting blade and the rotating shaft is less than the distance between the point of force applied to the compartment door and the rotating shaft when a person closes the compartment door. That is, the lever arm of the cutting blade is less than the lever arm of the point of force applied by the person. Under the same torque, the cutting force of the cutting blade on the liquid outlet is greater than the force applied by the person. This can help people with less strength to quickly and easily cut the liquid outlet and open the medicine bag.

[0025] 6. The door opening mechanism is designed to open and close in parallel with the main body. This allows the person applying force to be positioned directly opposite the cutting blade, preventing the door from deforming due to insufficient strength or the torque of the cutting blade if the force point is elsewhere. Lower-strength materials can be used to make the door, saving costs.

[0026] 7. Buckles are installed on the door to secure the medicine bag. At the same time, by securing the liquid outlet with buckles, the liquid outlet is prevented from shaking when the cutting blade cuts through it, thus achieving better cutting results.

[0027] 8. A receiving cavity is set on the door to accommodate the medicine bag, which can save the overall volume of the medicine bag opening device and save costs. At the same time, it is also convenient to install the medicine bag opening device on the nebulizer cup, handheld nebulizer, and nebulizer mask, minimizing the impact of the medicine bag opening device on the volume and weight of the nebulizer cup, handheld nebulizer, and nebulizer mask.

[0028] 9. A pressing part is set on the side of the medicine bag facing the medicine sac. After the medicine bag is opened, the operator can manually squeeze the medicine in the medicine sac into the medicine chamber without waiting for the medicine to flow out naturally, which is convenient and quick.

[0029] According to another aspect of the present invention, an atomizer is also provided, the atomizer comprising the medicine bag opening device described in any of the above embodiments.

[0056] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0057] First aspect of the embodiments

[0058] Figure 1 This is a schematic diagram of the overall structure of the medicine bag opening device according to an embodiment of the present invention.

[0059] Figure 7 This is a front view of the internal structure of the medicine bag opening device according to an embodiment of the present invention.

[0060] Figure 9 This is a schematic diagram of the structure of the medicine bag applicable to the embodiments of the present invention.

[0061] This invention provides a medicine bag opening device. The applicable medicine bag 5 includes at least a medicine sac portion 51, a liquid outlet portion 52, and a sealing portion 53. The medicine sac portion 51 contains liquid medicine, and one end is the liquid outlet portion 52, which communicates with the interior of the medicine sac portion 51. The sealing portion 53 is located at the other end of the liquid outlet portion 52 and seals that end. When opening the medicine bag 5, the sealing portion 53 needs to be cut and separated from the liquid outlet portion 52, allowing the liquid medicine in the medicine sac portion 51 to flow out through the liquid outlet portion 52.

[0062] The medicine bag opening device provided in this embodiment of the invention includes:

[0063] The main body 1 has a receiving portion 15 for accommodating the medicine bag 5; the main body 1 may exist as a separate component or may be directly disposed on the atomizing cup 4 or atomizer 4 as part of the atomizing cup 4 / atomizer 4.

[0064] The door 2 is located on one side of the main body 1 of the medicine bag opening device and has a mounting part for installing the medicine bag 5. When the medicine bag 5 is installed on the door 2, the medicine bag 5 will move synchronously with the movement of the door 2.

[0065] The medicine bag 5 has an opening part with a cutting blade 11. The cutting blade 11 is located inside the main body 1, directly opposite the liquid outlet part 52 of the medicine bag 5 when the door 2 is closed, and can cut it.

[0066] The medicine chamber 3 is located below the main body 1, with its inlet end positioned below the opening portion of the medicine bag 5. When the medicine bag 5 is opened, the liquid medicine flows out from the outlet portion 52 and into the medicine chamber 3. The outlet end 31 of the medicine chamber 3 is directly connected to the atomizing cup 4 / nebulizer 4, allowing the liquid medicine to flow directly into the medicine chamber 3 of the atomizing cup 4 / nebulizer 4. In one embodiment, the medicine chamber 3 of the medicine bag opening device can share a single medicine chamber 3 with the atomizing cup 4 / nebulizer 4, meaning the liquid medicine from the medicine bag 5 is directly atomized by the atomizing device of the atomizer 4 through the medicine chamber 3. For example, when the medicine bag opening device is applied to the vibrating nebulizer 4, the liquid outlet 31 of the medicine chamber 3 of the medicine bag opening device can be directly connected to the vibrating plate, so that the liquid medicine in the medicine chamber 3 can be directly atomized; when the medicine bag opening device is applied to the compressor nebulizer 4, the medicine bag opening device can be integrated with the nebulizing cup 4, and the medicine chamber 3 of the medicine bag opening device can be part of the medicine chamber 3 of the nebulizing cup 4, or the medicine chamber 3 of the medicine bag opening device can be connected to the medicine chamber 3 of the nebulizing cup 4 through a channel. The structure of the nebulizing cup 4 of the compressor nebulizer 4 is existing technology and will not be described in detail here.

[0067] By setting up a medicine bag opening device and installing a cutting blade 11 in the medicine bag opening device, the medicine bag 5 can be cut while the chamber door 2 is closed after the medicine bag 5 is installed, so that the medicine liquid can directly enter the medicine chamber 3. This not only makes it convenient and reliable to open the medicine bag 5 installed in the atomizing cup 4 / atomizer 4, but also effectively avoids medicine liquid contamination or spillage caused by opening the medicine bag 5 outside the atomizing cup 4 / atomizer 4.

[0068] Figure 2 This is a schematic diagram of the structure of the cutting blade 11 in the opening part of the medicine bag 5 of the medicine bag opening device according to an embodiment of the present invention;

[0069] In one embodiment, the cutting blade 11 has two parts 111 (112) on the left and right sides, and its cutting edge 111a (112a) is located on the opposite side of the two parts 111 (112). The distance between the cutting edges 111a (112a) of the cutting blade 11 gradually narrows from the door 2 toward the main body 1. That is, the distance between the two cutting edges 111a (112a) in the left and right direction gradually narrows from the back to the front direction. When the door 2 is closed, the liquid outlet 52 can be cut by the two parts 111 (112) of the cutting blade 11.

[0070] During the closing of the compartment door 2, the cutting blade 111a (112a) can gradually cut the liquid outlet 52 from both the left and right sides, achieving uniform cutting force and avoiding insufficient force when opening the medicine bag 5 for women with weak hands.

[0071] Figure 3This is a schematic diagram of another structure of the cutting blade 11 in the opening part of the medicine bag 5 of the medicine bag opening device according to an embodiment of the present invention;

[0072] In one embodiment, the left and right portions 111 (112) of the cutting blade 11 are of different sizes, and / or the central axis at the narrowest distance between the blades 111a (112a) is located on one side of the plane of motion of the central axis of the liquid outlet portion 52 during the closing of the compartment door 2.

[0073] After the door 2 is closed, the surface that passes through the center of the liquid outlet 52 of the medicine bag 5 and is parallel to both the front-back direction and the vertical direction (i.e., the plane of motion of the central axis of the liquid outlet 52 during the closing of the door 2) is designated as surface A; the surface that passes through the center point of the narrowest point of the blade 111a (112a) of the left and right parts 111 (112) of the cutting blade 11 and is parallel to surface A is designated as surface B. In one embodiment, surface A and surface B are not coplanar.

[0074] By setting two cutting blades 11 of different sizes, 111 (112) on the left and right sides, and / or making the A and B sides non-coplanar, the two blades 111a (112a) can achieve staggered cutting when cutting the liquid outlet 52. For example, one blade 111a first contacts the liquid outlet 52 and cuts one side of the liquid outlet 52, and then the door 2 is closed. The other blade 112a then contacts the liquid outlet 52 and cuts the other side of the liquid outlet 52. In this embodiment, it can prevent the blades 111a (112a) from blocking the liquid outlet 52 after cutting the liquid outlet 52, thus preventing poor liquid discharge. At the same time, it can also reduce the force required for the cutting blade 11 to cut the liquid outlet 52.

[0075] In one embodiment, the narrowest point between the blades 111a (112a) of the left and right parts 111 (112) is not 0. That is, after the blades 111a (112a) of the left and right parts 111 (112) have finished cutting the liquid outlet 52 of the medicine bag 5, the liquid outlet 52 and the sealing part 53 of the medicine bag 5 are still connected. When the atomization is completed and the medicine bag 5 needs to be removed, the user can remove the medicine bag 5 at once. The sealing part 53 will not remain in the medicine bag opening device due to being cut off, which makes it convenient for the user to clean the medicine bag opening device and related devices of the atomizer 4 (such as the atomizing cup 4) after the atomization is completed.

[0076] In one embodiment, the blade 111a (112a) has a serrated structure (not shown in the figure). The serrated structure can be a semi-circular serration or a triangular serration. The present invention does not limit the serrated structure of the blade 111a (112a). Using a serrated structure can more conveniently and quickly cut the liquid outlet 52 of the medicine bag 5.

[0077] In one embodiment, the cutting blade 11 is positioned relative to the rear of the liquid outlet 52 after the door 2 is fully closed. That is, during the closing process of the door 2, the cutting blade 11 cuts the liquid outlet 52. After the cutting blade 11 completes the cutting, the door 2 is not yet fully closed, and the liquid outlet 52 continues to move with the door 2. This results in the cutting blade 11 being positioned rear of the liquid outlet 52 after the door 2 is fully closed. In this embodiment, the cutting blade 11 will not block the liquid outlet 52, preventing poor liquid flow.

[0078] Figures 4a and 4b are schematic diagrams of the overall structure of the medicine bag 5 opening part of the medicine bag opening device according to an embodiment of the present invention.

[0079] In one embodiment, the opening part of the medicine bag 5 is further provided with a thrust stop 12. The thrust stop 12 is located inside the main body 1 and below the cutting blade 11, directly opposite the sealing part 53 of the medicine bag 5 when the door 2 is closed. When the thrust stop 12 contacts the sealing part 53 during the closing process of the door 2, the door 2 is not completely closed.

[0080] By setting a thrust stop 12 inside the main body 1, during the opening of the medicine bag 5, the thrust stop 12 restricts the movement trajectory of the sealing part 53. In conjunction with the action of the cutting blade 11 cutting the liquid outlet part 52, a faster cutting operation of the liquid outlet part 52 can be achieved. That is, when the cutting blade 11 cuts the liquid outlet part 52, the thrust stop 12 can restrict the sealing part 53 from continuing to move backward. The liquid outlet part 52 is both cut by the cutting blade 11 and torn by the sealing part 53, which no longer moves forward, thus causing the cut to continue to tear open, enhancing the cutting effect and realizing the opening of the medicine bag 5. At the same time, it can also effectively prevent the sealing part 53 from blocking the liquid outlet part 52 after it is cut open, thus preventing poor liquid flow.

[0081] In one embodiment, the thrust portion 12 can be closer to the door 2 on one side in the left-right direction than the other side. That is, during the closing of the door 2, the side of the thrust portion 12 closer to the door 2 contacts the sealing portion 53 first. When the door 2 continues to close, the liquid outlet portion 52 continues to move forward, while the sealing portion 53 will rotate under the obstruction of the thrust portion 12, thereby achieving greater tearing and better cutting of the sealing portion 53 and the liquid outlet portion 52.

[0082] Figure 5 This is a schematic diagram of one opening and closing method of the medicine bag opening device according to an embodiment of the present invention;

[0083] In one embodiment, one end of the door 2 is connected to one end of the main body 1 via a pivot 13 or a hinge. When the door 2 is opened or closed, the door 2 rotates around the pivot 13 to move away from or towards the main body 1.

[0084] The opening and closing mechanism of the door 2 opening device and the main body 1 is set to rotate. The distance between the cutting blade 11 and the rotating shaft 13 is less than the distance between the point of force applied to the door 2 and the rotating shaft 13 when a person closes the door 2. That is, the lever arm of the cutting blade 11 is less than the lever arm of the point of force applied by the person. Under the same torque, the cutting force of the cutting blade 11 on the liquid outlet 52 is greater than the force applied by the person. This can help people with less strength to quickly and easily cut the liquid outlet 52 and open the medicine bag 5.

[0085] Figure 6 This is a schematic diagram of another opening and closing method of the medicine bag opening device according to an embodiment of the present invention;

[0086] In one embodiment, one end of the door 2 is connected to one end of the main body 1 via a guide rail 14. When the door 2 is opened or closed, the plane on which the door 2 is located is parallel to or close to the plane on which the main body 1 is located.

[0087] The opening mechanism of the storage door 2 is designed to open and close in parallel with the main body 1. This allows the point of force application to be located directly opposite the cutting blade 11, preventing the storage door 2 from deforming due to insufficient strength or the torque exerted by the cutting blade 11 if the point of force application is elsewhere. In this embodiment, the manufacturer can use a lower-strength material to make the storage door 2, saving costs.

[0088] In one embodiment, the mounting part includes a buckle 21. When the medicine bag 5 is installed on the door 2, the buckle 21 can engage the liquid outlet 52 on the door 2. When the door 2 is closed, the buckle 21 is located above the cutting blade 11.

[0089] A buckle 21 is installed on the door 2 to secure the medicine bag 5. At the same time, by fixing the liquid outlet 52 with the buckle 21, the liquid outlet 52 can be prevented from shaking when the cutting blade 11 cuts the liquid outlet 52, thus achieving better cutting.

[0090] like Figure 1 As shown, in one embodiment, the mounting part includes a receiving cavity 22, which can accommodate at least a portion of the medicine bag 5 and fix the medicine bag 5 to the door 2.

[0091] A receiving cavity 22 is provided on the door 2 to accommodate the medicine bag 5, which can save the overall volume of the medicine bag opening device and save costs. At the same time, it is also convenient to install the medicine bag opening device on the atomizing cup 4, the handheld atomizer 4, and the atomizing mask, minimizing the impact of the medicine bag opening device on the volume and weight of the atomizing cup 4, the handheld atomizer 4, and the atomizing mask.

[0092] like Figure 1As shown, in one embodiment, a pressing part 23 is also provided on the other side of the compartment door 2 opposite to the main body 1. When the medicine bag 5 is placed inside the mounting part, the pressing part 23 is opposite to the medicine bag part 51.

[0093] The door 2 of the medicine bag opening device may also include a pressing part 23, which is provided on the outer wall of the door 2. When the medicine bag 5 is installed in the door 2, the pressing part 23 and the medicine bag part 51 are positioned opposite each other in the front-back direction. Thus, the pressing part 23 can squeeze the medicine bag part 51 of the medicine bag 5 placed in the medicine bag opening device. After the medicine bag 5 is opened, the operator can manually squeeze the liquid medicine in the medicine bag part 51 into the medicine chamber 3 without waiting for the liquid medicine to flow out naturally, which is convenient and quick.

[0094] In one embodiment, the pressing part 23 may be transparent. This allows the user to observe the remaining medication in the sac 51 through the pressing part 23, facilitating the use of the nebulizer cup / nebulizer.

[0095] Second aspect of the embodiments

[0096] This application also provides a nebulizer, which includes the medicine bag opening device described in the first aspect embodiment. The nebulizer can provide, for example, a gas and / or liquid for nebulization, and its nebulization method includes, but is not limited to, compression nebulization and vibration nebulization.
