Description

Technical Field

[0001] This invention relates to the technical field of respiratory sprays, and more particularly to a dual-channel respiratory medication delivery device. Background Technology

[0002] Respiratory medicine treatments often involve the use of multiple medications to achieve optimal therapeutic effects. For example, in treating conditions such as asthma, chronic obstructive pulmonary disease (COPD), or allergic rhinitis, it is often necessary to use anti-inflammatory drugs and bronchodilators simultaneously. These medications can be administered directly to the respiratory tract via inhaler, thus providing rapid onset of action and reducing systemic side effects.

[0003] Currently, most nasal sprays on the market are single-channel sprayers, meaning they can only hold one medication. For cases requiring combination therapy, patients must use different sprayers in batches, which not only increases the difficulty of operation and prolongs treatment time but may also reduce patient compliance. Furthermore, the discomfort caused by multiple sprays of different medications reduces patient acceptance, especially for children and the elderly, where the experience is even worse.

[0004] In summary, since existing nasal sprays fail to effectively integrate the administration of two drugs and lack an immediate mixing mechanism, this invention designs a dual-channel respiratory drug delivery device. Summary of the Invention

[0005] To overcome the shortcomings of existing nasal sprays in effectively integrating the administration of two drugs and lacking an immediate mixing mechanism, this invention provides a dual-channel respiratory drug delivery device.

[0006] A dual-channel respiratory medication delivery device includes a housing with an upper chamber and a lower chamber. A spray hood is connected to the side of the housing near the upper chamber. The housing has a first channel and a second channel, both connecting to the upper and lower chambers. A first one-way valve is fixedly connected to both the first and second channels, restricting the unidirectional flow of medication into the upper chamber. At least two rotating doors are rotatably connected to the side of the housing near the lower chamber. A first spray canister is placed in the lower chamber, with its nozzle communicating with the first channel. A lifting frame is slidably connected to the lower chamber, and the housing has a groove for raising and lowering the lifting frame, which passes through the groove. A second spray canister is placed in the lower chamber, with its nozzle communicating with the second channel. Both the first and second spray canisters are in contact with the lifting frame.

[0007] More preferably, both the first spray can and the second spray can consist of a can body, a pump assembly, a nozzle, and a conduit, wherein the pump assembly consists of a piston and a spring.

[0008] More preferably, it also includes a first connecting frame, which is slidably connected to the housing. The housing is rotatably connected to a rotating rod. The first connecting frame is fixedly connected to a bellows, which is slidably connected to the upper chamber of the housing. The bellows and the upper part of the housing form a cylinder piston structure. The rotating rod is rotatably connected to a push-pull rod, which is rotatably connected to the first connecting frame. A second one-way valve is fixedly connected to the side of the housing near the bellows. The second one-way valve restricts the liquid medicine in the upper chamber of the housing from flowing out unidirectionally to the spray hood.

[0009] More preferably, it also includes a second connecting frame, which is fixed to the side of the upper chamber of the outer shell near the spray hood. The second connecting frame has circumferentially distributed guide vanes fixed inside it. When the liquid medicine in the upper chamber of the outer shell enters the spray hood, it passes through the guide vanes. The guide vanes disperse the liquid medicine in a vortex-like manner to assist in the mixing of the liquid medicine.

[0010] More preferably, it also includes a locking tooth, which is fixedly connected to the first connecting frame. A fixing frame is fixedly connected to the side of the outer shell near the locking tooth. The fixing frame is rotatably connected to a first screw. The first screw is threadedly connected to a lifting block. The lifting block is slidably connected to the fixing frame. The lifting block is slidably connected to a locking block. The locking block moves to one side and engages with the locking tooth. A spring is fixedly connected between the locking block and the lifting block.

[0011] More preferably, it also includes a handle, which is rotatably connected to the housing and fixedly connected to the rotating rod.

[0012] More preferably, it also includes a connecting rod, which is rotatably connected between the handle and the lifting frame.

[0013] More preferably, it also includes a rotating block, which is rotatably connected to the outer casing. The rotating block is fixedly connected to a second screw, which is threadedly connected to a sliding block. The sliding block is slidably connected to the outer casing. The handle is fixedly connected to a blocking block, which rotates to contact the sliding block.

[0014] More preferably, the sliding block has a blocking groove, which is composed of a slanted groove and a straight groove, and the blocking block rotates to contact the blocking groove of the sliding block.

[0015] The present invention has the following advantages:

[0016] 1. This invention uses a first spray can and a second spray can to hold two different medications respectively. By repeatedly pushing the lifting frame up and down, the two medications can be sprayed simultaneously, achieving a synergistic effect of the medications, enhancing the therapeutic effect, avoiding the inconvenience of administering medications in batches, and improving the convenience of use.

[0017] 2. The design of this invention, which sprays the medication into the nasal cavity simultaneously, can reduce the discomfort caused by multiple sprays and improve patient acceptance. Moreover, since the medication is mixed immediately and sprayed directly into the nasal cavity, the time the medication is exposed to the air is reduced, preventing unnecessary volatilization or contamination.

[0018] 3. By rotating the rotating rod and compressing the bellows, the liquid medicine in the first and second channels is accelerated into the upper chamber of the outer shell under negative pressure. The liquid medicine in the upper chamber is pushed out of the spray hood by the bellows reset, which solves the problem that the pump assembly of the first and second spray cans is not enough to pump out the liquid medicine, and ensures the effective supply of medicine.

[0019] 4. By adjusting the first screw, the present invention can make the locking block lock the locking teeth. Under the action of the spring, the locking teeth move slowly upward, thereby slowing down the reset speed of the bellows and allowing the liquid medicine to be slowly and in small amounts to be discharged, reducing the patient's discomfort. It is especially suitable for sensitive groups such as the elderly and children, and improves their medication comfort and compliance.

[0020] 5. This invention simplifies the operation by replacing the manual operation of simultaneously pushing up the lifting frame and rotating the lever by pressing the handle, reducing the difficulty of operation for users and improving the convenience and labor-saving of use.

[0021] 6. This invention adjusts the rotating block to change the rotatable angle of the handle, allowing for flexible control of the amount of medicine sprayed each time. This enables personalized adjustments based on the patient's specific needs, providing more precise treatment plans and meeting the needs of different patients. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0035] Example 1: A dual-channel respiratory drug delivery device, such as... Figure 1-Figure 5As shown, the device includes a housing 101, which has an upper chamber and a lower chamber. A spray hood 102 is connected to the side of the housing 101 near the upper chamber. A first channel 103 and a second channel 104 are respectively opened on the left and right sides of the housing 101, both connecting to the upper and lower chambers. A first one-way valve 105 is fixedly connected to both the first channel 103 and the second channel 104, restricting the unidirectional flow of the liquid medicine into the upper chamber of the housing 101. The first one-way valve 105 has multiple spray holes. Two rotating doors 106 are rotatably connected to the left side of the housing 101. A first spray can 107 is placed on the upper side of the lower chamber of the housing 101. The nozzle of spray can 107 is connected to the first channel 103. A lifting frame 108 is slidably connected to the lower cavity of the outer shell 101. A sliding groove for lifting the lifting frame 108 is opened on the lower right side of the outer shell 101. The lifting frame 108 passes through the sliding groove. A second spray can 109 is placed on the lower side of the lower cavity of the outer shell 101. Both the first spray can 107 and the second spray can 109 are composed of a can body, a pump assembly, a nozzle, and a conduit. The pump assembly is composed of a piston and a spring. The nozzle of the second spray can 109 is connected to the second channel 104. Both the first spray can 107 and the second spray can 109 are in contact with the lifting frame 108. When the lifting frame 108 rises, it drives the can bodies of the first spray can 107 and the second spray can 109 to move upwards simultaneously.

[0036] When two medications need to be administered to the respiratory tract, the two medications can be stored in the first spray can 107 and the second spray can 109, respectively. Then, open the upper and lower rotating doors 106, and place the first spray can 107 and the second spray can 109 on the upper and lower sides of the lower cavity of the outer shell 101, respectively, so that the first spray can 107 and the second spray can 109 are both placed on the lifting frame 108. The nozzles of the first spray can 107 and the second spray can 109 are against the inner wall of the outer shell 101 and are respectively connected to the first channel 103 and the second channel 104. Then, close the rotating doors 106, cover the nostrils with the spray mask 102, and then push it upwards. The lifting frame 108 causes the canisters of the first spray can 107 and the second spray can 109 to move upward relative to the pump assembly, thereby compressing the air in the pump chamber and increasing the internal pressure. This pressure forces the liquid medicine in the first spray can 107 and the second spray can 109 to be rapidly discharged into the first channel 103 and the second channel 104 through their respective nozzles, and then converges in the upper chamber of the outer shell 101 for mixing. Finally, it is sprayed into the nasal cavity in the form of a spray through the spray nozzle 102. During this process, the first one-way valve 105 prevents the sprayed liquid medicine from flowing back downward. Afterward, the lifting frame 108 is pulled down, and this process is repeated to administer the medicine into the respiratory tract multiple times.

[0037] In summary, by setting up a first spray can 107 and a second spray can 109 to hold two different drugs respectively, and by repeatedly pushing the lifting frame 108 up and down, the two drugs can be sprayed simultaneously, achieving a synergistic effect of the drugs, enhancing the therapeutic effect, avoiding the inconvenience of administering drugs in batches, and improving the convenience of use.

[0038] The design of this invention, which involves simultaneous spraying into the nasal cavity, can reduce the discomfort caused by multiple sprays and improve patient acceptance. Furthermore, because the medication is mixed instantly and sprayed directly into the nasal cavity, it reduces the time the medication is exposed to the air, preventing unnecessary volatilization or contamination.

[0039] Example 2: Based on Example 1, such as Figure 6 and Figure 7 As shown, it also includes a first connecting frame 201, which is slidably connected to the housing 101. A rotating rod 202 is rotatably connected to the lower front side of the housing 101. A bellows 203 is fixedly connected to the top of the first connecting frame 201. The first connecting frame 201 moves downward to compress the bellows 203. The bellows 203 is slidably connected to the upper chamber of the housing 101. The bellows 203 and the upper part of the housing 101 form a cylinder piston structure. A push-pull rod 204 is rotatably connected to the rotating rod 202. The push-pull rod 204 is rotatably connected to the first connecting frame 201. A second one-way valve 205 is fixedly connected to the upper side of the housing 101. The second one-way valve 205 restricts the liquid medicine in the upper chamber of the housing 101 from flowing out unidirectionally to the spray hood 102. The second one-way valve 205 is also provided with multiple spray holes.

[0040] When the lifting frame 108 is pushed up, the rotating rod 202 is rotated simultaneously, causing the rotating rod 202 to pull the first connecting frame 201 downward through the push-pull rod 204. This causes the bellows 203 to be compressed downward, so that the liquid medicine in the first channel 103 and the second channel 104 is accelerated and drawn into the upper chamber of the outer shell 101 under negative pressure. During this process, the second one-way valve 205 prevents external air from entering the upper chamber of the outer shell 101. When the lifting frame 108 is pulled down, the rotating rod 202 is released, and the bellows 203 returns to its original position, thereby pushing the liquid medicine in the upper chamber of the outer shell 101 out of the spray hood 102. This avoids the pump assembly of the first spray can 107 and the second spray can 109 being insufficient to pump out the liquid medicine. At the same time, the return of the bellows 203 causes the first connecting frame 201 to move upward. The first connecting frame 201 drives the rotating rod 202 to reverse and return to its original position through the push-pull rod 204.

[0041] like Figure 8 and Figure 9As shown, it also includes a second connecting frame 301, which is fixed to the upper cavity of the outer shell 101. Guide blades 302 distributed in a circumferential manner are fixed inside the second connecting frame 301. When the liquid medicine in the upper cavity of the outer shell 101 enters the spray hood 102, it passes through the guide blades 302. The guide blades 302 disperse the liquid medicine in a vortex-like manner to assist in the mixing of the two liquid medicines.

[0042] like Figure 10 and Figure 11 As shown, it also includes a locking tooth 401, which is fixedly connected to the first connecting frame 201. A fixing frame 402 is fixedly connected to the side of the outer shell 101 near the locking tooth 401. A first screw 403 is rotatably connected to the fixing frame 402. A lifting block 404 is threadedly connected to the first screw 403. The lifting block 404 is slidably connected to the fixing frame 402. A locking block 405 is slidably connected to the side of the lifting block 404 near the locking tooth 401. The locking block 405 moves to one side and engages with the locking tooth 401. A spring 406 is fixedly connected between the locking block 405 and the lifting block 404.

[0043] If the bellows 203 quickly returns to its original position, it will rapidly push all the medication in the upper chamber of the outer shell 101 into the nasal cavity each time, causing severe discomfort to patients, especially the elderly and children. Therefore, in this situation, it is necessary to slow down the speed of medication delivery so that the medication can be delivered slowly in small amounts. The specific adjustment operation is as follows: Before releasing the rotating rod 202, first rotate the first screw 403 so that the lifting block 404 moves the locking block 405 through the spring 406 to lock the locking tooth 401. Then, after releasing the rotating rod 202, the first connecting frame 201 moves the locking tooth 401 upward. Under the elastic resistance formed by the spring 406 and the locking block 405, the locking tooth 401 moves upward slowly, thereby causing the first connecting frame 201 to move upward slowly, which in turn causes the bellows 203 to move upward slowly, thus allowing the medication to be delivered slowly in small amounts, avoiding discomfort to the patient.

[0044] Example 3: Based on Example 2, such as Figure 11 As shown, it also includes a handle 501, which is rotatably connected to the right side of the housing 101, fixedly connected to the rotating rod 202, and rotatably connected to the lifting frame 108 by a connecting rod 502.

[0045] Since each spraying requires simultaneously pushing up the lifting frame 108 and rotating the lever 202, the operation is inconvenient and laborious. Therefore, by pressing the handle 501 on the side closer to the outer casing 101, the pressing handle 501 drives the lifting frame 108 to move upward through the connecting rod 502, and at the same time drives the lever 202 to rotate, making the operation simple, convenient and labor-saving.

[0046] like Figure 11As shown, it also includes a rotating block 601, which is rotatably connected to the right side of the outer casing 101. A second screw 602 is fixedly connected to the rotating block 601, and a sliding block 603 is threadedly connected to the second screw 602. The sliding block 603 is slidably connected to the outer casing 101. A blocking groove is opened on the front side of the sliding block 603. The blocking groove is formed by connecting a lower inclined groove and an upper straight groove. A blocking block 604 is fixedly connected to the upper part of the handle 501. The blocking block 604 can rotate towards the side closer to the outer casing 101 to contact the blocking groove of the sliding block 603.

[0047] The rotation angle of the handle 501 can be adjusted to adjust the rotation angle of the rotating rod 202, thereby adjusting the amount of pesticide sprayed each time. The specific operation of adjusting the rotation angle of the handle 501 is as follows: When it is necessary to reduce the amount of pesticide sprayed each time, control the rotating block 601 to rotate, so that the second screw 602 rotates, thereby driving the sliding block 603 to move downward. The more the sliding block 603 moves downward, the earlier the blocking block 604 will contact the blocking groove of the sliding block 603 when the handle 501 rotates, thus making the rotation angle of the handle 501 smaller, and thus making the amount of pesticide sprayed each time smaller. Conversely, the more the handle 501 rotates, the more the amount of pesticide sprayed each time.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
