Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a medicine bag shearing device and an atomizing cup. Background Art

[0002] Atomization therapy mainly refers to aerosol inhalation therapy. An aerosol refers to tiny solid or liquid particles suspended in the air. Therefore, aerosol inhalation therapy is to use an atomizing device to disperse the drug into tiny droplets or particles, make them suspended in the gas, and enter the respiratory tract and lungs to achieve the purpose of cleaning the airway, humidifying the airway, local treatment and systemic treatment. Existing atomizers generally use the method of atomizing the liquid medicine. Before the start of atomization therapy, the medicine bag is first torn open and then poured into the medicine storage cavity of the atomizer. During the operation process, it is easy to cause liquid medicine pollution or splashing. In order to ensure the flatness of the medicine bag shearing, a special shearing tool is also required, which is inconvenient to use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a medicine bag shearing mechanism and an atomizing cup aiming at the above defects of the prior art, aiming to solve the problems of inconvenient opening of the medicine bag, easy pollution or splashing of the liquid medicine existing in the existing atomizer.

[0004] The technical solution adopted by the present invention to solve its technical problem is: to provide a medicine bag shearing device, including:

[0005] A rotating mechanism, including an installation through hole penetrating through the rotating mechanism and a pressing part arranged on the side wall of the rotating mechanism;

[0006] A shearing mechanism, arranged at the bottom of the rotating mechanism, including an installation cavity and a liquid guiding hole penetrating through the shearing mechanism, and a cutting knife is arranged on the side wall of the liquid guiding hole; and

[0007] A cup cover, which is openably and closably arranged on the top of the rotating mechanism;

[0008] Wherein, when the cup cover is opened, a medicine bag composed of a medicine capsule, a connecting part and a fixing part can be correspondingly placed in the accommodation space jointly formed by the installation cavity and the installation through hole; when the cup cover is closed, the cup cover abuts against the top end of the medicine capsule. At this time, if the rotating mechanism is rotated relative to the shearing mechanism, so that the installation through hole and the medicine capsule therein are changed from a position above the installation cavity to a position above the liquid guiding hole, then the cutting knife can correspondingly separate the connecting part from the fixing part.

[0009] Furthermore, there are two installation through holes, two installation cavities and two pressing parts. The two installation through holes and the two pressing parts are symmetrically arranged on the rotating mechanism respectively, and the two installation cavities are arranged in parallel on both sides of the liquid guiding hole.

[0010] Further, the shearing mechanism further includes two parallel installation grooves, the two installation grooves are perpendicular to the two installation cavities, a pushing block and a second elastic member are arranged in the installation grooves, and two ends of the second elastic member are respectively abutted against the bottom of the installation groove and the pushing block; and bearing plates are arranged at both ends of the pushing block, and the bearing plates extend into the installation cavity to support the bottom end of the fixing portion of the medicine bag.

[0011] Further, a second through hole is provided on the side wall of the installation cavity to facilitate the replacement of the medicine bag.

[0012] Further, the rotating mechanism is provided with a base, an annular sliding groove is arranged inside the base, and a convex strip matched with the annular sliding groove is arranged at the top of the shearing mechanism.

[0013] Further, a plurality of expansion openings are formed in the side wall of the base to facilitate the convex strip to enter the annular sliding groove.

[0014] The present invention further provides an atomizing cup, which includes the aforementioned medicine bag shearing device, as well as a cup body, a liquid guiding funnel and an atomizing rod. The cup body is provided with a mist suction port, a medicine storage cavity and a conical portion. The mist suction port is communicated with the medicine storage cavity.

An air inlet pipe communicating the inside and outside of the medicine storage cavity is arranged inside the conical portion. The liquid guiding funnel is matched with the conical portion to form a liquid guiding channel; the atomizing rod is installed at the bottom of the medicine bag shearing device, and a partition is arranged at the bottom of the atomizing rod, and the partition is located above the air inlet pipe.

[0015] Further, the top of the atomizing rod is fixedly connected to the rotating mechanism. A liquid receiving plate and a baffle arranged on the liquid receiving plate are arranged on the atomizing rod. The liquid receiving plate is used for receiving the liquid medicine from the liquid guiding hole, and the baffle is used for blocking and opening the mist suction port.

[0016] Further, a fourth through hole is arranged in the middle of the rotating mechanism, a groove is arranged at the bottom of the fourth through hole, and an annular clamping ring and a convex portion are arranged at the top of the atomizing rod; when the convex portion is located in the groove, the annular clamping ring abuts against the top of the fourth through hole.

[0040] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0041] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art.

[0042] Embodiment 1

[0043] As Figures 1 to 4 shown, the present invention provides a medicine bag shearing device 10, which includes a cup cover 1, a rotating mechanism 2 and a shearing mechanism 3. The cup cover 1 is disposed on the top of the rotating mechanism 2 in an openable and closable manner, with one side rotatably connected to the rotating mechanism 2 and a card slot 11 provided on the other side. A buckle 21 is provided on the rotating mechanism 2 and is engaged with the card slot 11. When the buckle 21 is engaged with the card slot 11, the cup cover 1 is closed on the rotating mechanism 2. The rotating mechanism 2 is provided with a base 22, and an annular sliding groove 221 is provided inside the base 22. A convex strip 31 is provided on the top of the shearing mechanism 3 and is engaged with the annular sliding groove 221. After the convex strip 31 is installed in the annular sliding groove 221, the rotating mechanism 2 and the shearing mechanism 3 are fixedly connected to each other in the central axis direction of the rotating mechanism 2, and under the cooperation of the convex strip 31 and the annular sliding groove 221, the rotating mechanism 2 can rotate relative to the shearing mechanism 3 around the central axis. Further, a plurality of expansion openings 222 are formed on the side wall of the base 22, and the expansion openings 222 divide the annular sliding groove 221 into several segments. When the convex strip 31 is pressed into the annular sliding groove 221, the expansion openings 222 are deformed, and the diameter of the annular sliding groove 221 can be enlarged to facilitate the convex strip 31 to enter the annular sliding groove 221. The convex strip 31 is an annular convex strip 31 to increase the connection stability between the rotating mechanism 2 and the shearing mechanism 3.

[0044] As Figure 3 and Figure 4As shown in the figure, the shearing mechanism 3 is arranged at the bottom of the rotating mechanism 2, and the rotating mechanism 2 can rotate relative to the shearing mechanism 3. The rotating mechanism 2 includes an installation through hole 23 penetrating through the rotating mechanism 2 and a pressing part 24 arranged on the side wall of the rotating mechanism 2. The shearing mechanism 3 includes an installation cavity 32 and a liquid guiding hole 33 penetrating through the shearing mechanism 3. A cutter 331 is arranged on the side wall of the liquid guiding hole 33 for shearing the connecting part 302 of the medicine bag 30. The installation through hole 23 cooperates with the installation cavity 32 to form a receiving space for respectively accommodating the medicine sac 301 and the fixing part 303 of the medicine bag 30. The connecting part 302 of the medicine bag 30 is respectively connected to the medicine sac 301 and the fixing part 303. When the cup cover 1 is covered on the rotating mechanism 2, the medicine sac 301 corresponds to the position of the pressing part 24, the fixing part 303 is located in the installation cavity 32, and the connecting part 302 corresponds to the position of the cutter 331.

[0045] When it is necessary to shear the medicine bag 30, open the cup cover 1, put the medicine bag 30 through the installation through hole 23 until the fixing part 303 reaches the inside of the installation cavity 32; then cover the cup cover 1. The cup cover 1 can abut against the top end of the medicine sac 301, and rotate the rotating mechanism 2. The rotating mechanism 2 drives the medicine sac 301 to rotate around the central axis of the rotating mechanism 2 through the installation through hole 23. At the same time, the fixing part 303 is located in the installation cavity 32 and does not rotate together with the medicine sac 301. Therefore, a torsion force will be generated between the medicine sac 301 and the fixing part 303, and the connecting part 302 will be deformed and contact the cutter 331 until the connecting part 302 is completely cut off by the cutter 331 and is located above the liquid guiding hole 33. At this time, by pressing the medicine sac 301 through the pressing part 24, the liquid medicine can flow out of the medicine sac 301 and flow into the liquid guiding hole 33 for guiding.

[0046] Preferably, in this embodiment, the pressing part 24 is a first through hole penetrating through the side wall of the rotating mechanism 2. The user can put a finger into the first through hole to press the medicine sac 301, and the user can observe the installation position of the medicine bag 30 through the first through hole to ensure that the medicine bag 30 is correctly placed in the medicine bag shearing device 10. In other embodiments, the pressing part 24 can be a first elastic member, and the user can press the first elastic member to further press the medicine sac 301.

[0047] For the medicine bag shearing device 10 provided by the present invention, only by rotating the rotating mechanism 2 can the shearing of the medicine bag 30 be realized, and there is no need to additionally equip a special shearing tool for the medicine bag 30, and the operation is convenient and fast. Moreover, when the medicine bag 30 is sheared, the user does not contact the shearing position of the medicine bag 30, which can avoid the liquid medicine pollution caused by human contact. After the medicine bag 30 is sheared, the liquid medicine can directly flow into the liquid guiding hole 33, and the liquid medicine will not splash, which can prevent the waste of the liquid medicine.

[0048] More preferably, there are two mounting through holes 23, two mounting cavities 32 and two pressing parts 24. The two mounting through holes 23 and the two pressing parts 24 are symmetrically arranged on the rotating mechanism 2 respectively, and the two mounting cavities 32 are arranged in parallel on both sides of the liquid guiding hole 33. Before use, two medicine bags 30 can be loaded into the medicine bag cutting device 10, which is beneficial to improving the space utilization rate of the medicine bag cutting device 10, and is convenient to carry around, avoiding forgetting the medicine bag 30 when going out; and when the rotating mechanism 2 is rotated, two medicine bags 30 can be cut, improving the cutting efficiency, and a large amount of liquid medicine can be injected into the liquid guiding hole 33 at one time.

[0049] The cutting mechanism 3 further includes two mounting grooves 34 arranged in parallel. The two mounting grooves 34 are perpendicular to the two mounting cavities 32. A push block 341 and a second elastic member 342 are arranged in the mounting groove 34. Two ends of the second elastic member 342 are respectively in contact with the bottom of the mounting groove 34 and the push block 341, and the second elastic member 342 can push the push block 341 to move up and down along the mounting groove 34. Bearing plates 3411 are arranged on both sides of the push block 341, and the bearing plates 3411 can extend into the mounting cavity 32 to support the bottom end of the fixing part 303. When the medicine bag 30 is placed in the mounting cavity 32, its fixing part 303 is in contact with the bearing plate 3411. When the cup cover 1 is closed on the rotating mechanism 2, the cup cover 1 and the bearing plate 3411 are respectively in contact with both ends of the medicine bag 30 to tightly fix the medicine bag 30 inside the medicine bag cutting device 10. After the connecting part 302 is cut off, the second elastic member 342 can push the push block 341 to reset, driving the fixing part 303 to move up. When replacing the medicine bag 30, it is convenient to take out the fixing part 303. Preferably, when the rotating mechanism 2 rotates 90°, the connecting part 302 can be cut off, and the connecting part 302 can rotate from above the mounting cavity 32 to above the liquid guiding hole 33. A second through hole 321 is arranged on the side wall of the mounting cavity 32, which is convenient for pushing up the fixing part 303 through the second through hole 321 to prevent the fixing part 303 from being blocked in the mounting cavity 32 when replacing the medicine bag 30.

[0050] As Figure 4 shown, a handle 35 is further arranged on the side wall of the cutting mechanism 3, which is convenient for the user to hold and carry the medicine bag cutting device 10, and the medicine bag cutting device 10 can be hung through the handle 35.

[0051] Embodiment 2

[0052] As Figures 5 to 10As shown in the figure, this embodiment provides an atomizing cup 20, which includes the medicine bag shearing device 10 described in Embodiment 1, as well as a cup body 4, a liquid guiding funnel 5, and an atomizing rod 6. The cup body 4 is provided with a mist suction port 41, a medicine storage cavity 42, and a conical part 43. The mist suction port 41 is communicated with the medicine storage cavity 42. The conical part 43 is arranged at the bottom of the medicine storage cavity 42. An air inlet pipe 431 communicating the inside and outside of the medicine storage cavity 42 is arranged in the conical part 43. The liquid guiding funnel 5 is matched with the conical part 43 to form a liquid guiding channel. The atomizing rod 6 is installed at the bottom of the medicine bag shearing device 10 and extends into the medicine storage cavity 42. A partition 61 is arranged at the bottom of the atomizing rod 6, and the partition 61 is located above the air inlet pipe 431.

[0053] Specifically, as Figure 8 shown, the liquid guiding funnel 5 is in a shape with a narrow top and a wide bottom, and it corresponds to the aforementioned conical part 43. The top of the liquid guiding funnel 5 is provided with a liquid outlet 51. The liquid guiding funnel 5 can be stacked and covered on the conical part 43. A liquid guiding channel is formed between the outer side surface of the conical part 43 and the inner side surface of the liquid guiding funnel 5. As a preference, a plurality of convex columns 52 are arranged at the bottom of the liquid guiding funnel 5, and the convex columns 52 are in contact with the bottom of the medicine storage cavity 42, which is convenient for the liquid medicine to flow into the liquid guiding channel.

[0054] When a compressor is connected to the air inlet pipe 431 and the compressor conveys high-pressure gas into the medicine storage cavity 42 through the air inlet pipe 431, a low pressure will be generated near the outlet of the air inlet pipe 431, that is, a low-pressure environment will be generated in the liquid guiding channel. The liquid medicine in the medicine storage cavity 42 will flow upward through the liquid guiding channel to the liquid outlet 51 under the action of the air pressure difference. The partition 61 is close to the upper part of the liquid outlet 51, and the liquid medicine sprayed out from the liquid outlet 51 will hit the partition 61 to generate a spray.

[0055] Furthermore, the top of the atomizing rod 6 is fixedly connected to the rotating mechanism 2. A liquid receiving plate 62 and a baffle 63 arranged on the liquid receiving plate 62 are also arranged on the atomizing rod 6. The liquid receiving plate 62 is used to receive the liquid medicine from the liquid guiding hole 33. The liquid receiving plate 62 is in a funnel shape with a wide top and a narrow bottom, and a third through hole 621 is arranged in the middle of the liquid receiving plate 62 for pouring the collected liquid medicine into the medicine storage cavity 42. The baffle 63 is used to block and open the mist suction port 41. Preferably, baffles 63 are symmetrically arranged on both sides of the liquid receiving plate 62, which is convenient for the rotating mechanism 2 to open the mist suction port 41 whether it rotates forward or backward. A hollow cylinder 64 with both ends penetrating is arranged below the third through hole 621, which is convenient for the liquid medicine to flow into the medicine storage cavity 42. The partition 61 is arranged inside the hollow cylinder 64. A support frame 53 is arranged outside the liquid guiding funnel 5, and the support frame 53 can be in contact with the hollow cylinder 64, so that there is a certain distance between the partition 61 and the liquid outlet 51, ensuring that the liquid medicine sprayed out from the liquid outlet 51 can be atomized when it reaches the partition 61.

[0056] Before the rotating mechanism 2 rotates to cut the medicine bag 30, the baffle 63 can block the mist suction port 41. When the rotating mechanism 2 rotates, the atomizing rod 6 rotates together with the rotating mechanism 2. At the same time, the baffle 63 moves away from the position of the mist suction port 41 to open the mist suction port 41.

[0057] Specifically, as Figure 3 and Figure 9 shown, a fourth through hole 25 is provided in the middle of the rotating mechanism 2, and a groove 251 is provided at the bottom of the fourth through hole 25. An annular snap ring 65 and a convex portion 66 are provided at the top of the atomizing rod 6. When the convex portion 66 is located in the groove 251, the annular snap ring 65 abuts against the top of the fourth through hole 25, that is, the distance between the annular snap ring 65 and the convex portion 66 is equal to the distance between the top of the fourth through hole 25 and the groove 251, so that the atomizing rod 6 is more tightly connected to the rotating mechanism 2. More preferably, a conical inclined surface 67 and a telescopic groove 68 are provided at the top of the atomizing rod 6. The conical inclined surface 67 is located above the annular snap ring 65. The telescopic groove 68 penetrates through the top of the atomizing rod 6 and extends to the position of the convex portion 66. When the atomizing rod 6 needs to be assembled to the rotating mechanism 2, the atomizing rod 6 first passes through the liquid guide hole 33, and the conical inclined surface 67 contacts the bottom of the fourth through hole 25. When a certain thrust is applied, the two sides of the telescopic groove 68 approach each other, and the diameter of the top of the atomizing rod 6 decreases, facilitating the annular snap ring 65 to pass through the fourth through hole 25.

[0058] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
