Description

Technical Field

[0001] The invention relates to the technical field of respiratory medicine spraying, in particular to a double-channel respiratory medicine dispenser. Background Art

[0002] Respiratory treatment often involves the use of multiple drugs to achieve the best therapeutic effect. For example, when treating diseases such as asthma, chronic obstructive pulmonary disease (COPD) or allergic rhinitis, it is often necessary to use anti-inflammatory drugs and bronchodilators at the same time. These drugs can act directly on the respiratory tract in the form of a spray, so as to quickly take effect and reduce systemic side effects.

[0003] At present, nasal sprayers on the market are usually single-channel sprayers, which can only hold one drug. For situations where combined medication is required, patients must use different sprayers in batches, which not only increases the difficulty of operation and prolongs the treatment time, but may also reduce patient compliance. In addition, the discomfort caused by multiple sprays of different drugs will reduce patient acceptance, especially for children and the elderly, the experience is even worse.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example 1: A dual-channel respiratory medicine dispenser, such as Figure 1-Figure 5As shown, it includes a shell 101, the shell 101 has an upper chamber and a lower chamber, the side of the shell 101 close to the upper chamber is connected to a spray hood 102, the left and right sides of the shell 101 are respectively provided with a first channel 103 and a second channel 104, the first channel 103 and the second channel 104 are connected to the upper chamber and the lower chamber of the shell 101, the first channel 103 and the second channel 104 are both fixed with a first check valve 105, the first check valve 105 limits the one-way flow of liquid medicine into the upper chamber of the shell 101, the first check valve 105 is provided with a plurality of spray holes, the left side of the shell 101 is rotatably connected to an upper and lower rotating door 106, a first spray can 107 is placed on the upper side of the lower chamber of the shell 101, and the first The nozzle of the spray can 107 is communicated with the first channel 103, and a lifting frame 108 is slidably connected in the lower chamber of the shell 101. A slide groove for lifting the lifting frame 108 is opened at the lower right part of the shell 101, and the lifting frame 108 runs through the slide groove. A second spray can 109 is placed on the lower side of the lower chamber of the shell 101. The first spray can 107 and the second spray can 109 are both composed of a tank body, a pump assembly, a nozzle and a conduit, wherein the pump assembly is composed of a piston and a spring, and the nozzle of the second spray can 109 is communicated with the second channel 104, and the first spray can 107 and the second spray can 109 are both in contact with the lifting frame 108. When the lifting frame 108 rises upward, it drives the tank bodies of the first spray can 107 and the second spray can 109 to move upward at the same time.

[0035] When two drugs need to be administered to the respiratory tract, the two drugs can be stored in the first spray can 107 and the second spray can 109 respectively, and then the upper and lower rotating doors 106 are opened, and the first spray can 107 and the second spray can 109 are placed in the upper and lower sides of the lower chamber of the shell 101 respectively, and the first spray can 107 and the second spray can 109 are placed on the lifting frame 108, and the nozzles of the first spray can 107 and the second spray can 109 are respectively against the inner wall of the shell 101, and are connected with the first channel 103 and the second channel 104 respectively, and then the rotating door 106 is closed, and the spray cover 102 covers the nostrils, and then pushes upward. The lifting frame 108 enables the first spray can 107 and the second spray can 109 to move upward relative to the pump assembly to compress the air in the pump chamber and increase the internal pressure. This pressure forces the liquid medicine in the first spray can 107 and the second spray can 109 to be quickly discharged into the first channel 103 and the second channel 104 through their respective nozzles, and to be gathered in the upper chamber of the shell 101 for mixing, and finally sprayed into the nasal cavity in the form of a spray through the spray cover 102. In this process, the first one-way valve 105 prevents the sprayed liquid medicine from flowing back downward. Afterwards, the lifting frame 108 is pulled down, and this process is repeated to administer the medicine into the respiratory tract multiple times.

[0036] In summary, the present invention provides a first spray can 107 and a second spray can 109 to respectively contain two drugs, and then repeatedly pushes the lifting frame 108 up and down to simultaneously complete the spray administration of the two drugs, thereby achieving the synergistic effect of the drugs and enhancing the therapeutic effect, while avoiding the trouble of administering the drugs in batches and improving the convenience of use.

[0037] The design of synchronous spraying into the nasal cavity of the present invention can reduce the discomfort caused by multiple spraying and improve the patient's acceptance. Moreover, since the drugs are mixed immediately and sprayed directly into the nasal cavity, the exposure time of the drugs in the air is reduced, thus preventing unnecessary volatilization or pollution.

[0038] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, it also includes a first connecting frame 201, which is slidably connected to the shell 101, and the lower front side of the shell 101 is rotatably connected to a rotating rod 202, and the top of the first connecting frame 201 is fixedly connected to a bellows 203. The first connecting frame 201 moves downward to compress the bellows 203, and the bellows 203 is slidably connected to the upper chamber of the shell 101. The bellows 203 and the upper part of the shell 101 form a cylinder piston structure, and the rotating rod 202 is rotatably connected to a push-pull rod 204, and 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 shell 101, and the second one-way valve 205 limits the one-way outflow of the liquid in the upper chamber of the shell 101 to the spray hood 102, and the second one-way valve 205 is also provided with a plurality of spray holes.

[0039] When the lifting frame 108 is pushed up, the rotating rod 202 is rotated at the same time, so that the rotating rod 202 pulls the first connecting frame 201 downward through the push-pull rod 204, thereby driving the bellows 203 to compress downward, so that the liquid medicine in the first channel 103 and the second channel 104 is accelerated to be drawn into the upper chamber of the shell 101 under the action of negative pressure. In this process, the second one-way valve 205 prevents external air from entering the upper chamber of the shell 101. When the lifting frame 108 is pulled down, the rotating rod 202 is released, and the bellows 203 is reset upward, thereby pushing the liquid medicine in the upper chamber of the shell 101 out of the spray hood 102. In this way, it is prevented that the pump assembly of the first spray can 107 and the second spray can 109 is insufficient to pump out the liquid medicine. At the same time, the bellows 203 is reset to drive the first connecting frame 201 to move upward, and the first connecting frame 201 drives the rotating rod 202 to reverse and reset through the push-pull rod 204.

[0040] like Figure 8 and Fig. 9As shown, it also includes a second connecting frame 301, which is fixedly connected to the upper chamber of the shell 101. The second connecting frame 301 has circumferentially distributed guide blades 302 fixedly connected therein. The liquid medicine in the upper chamber of the shell 101 passes through the guide blades 302 during the process of entering the spray hood 102. The guide blades 302 evenly disperse the liquid medicine in a vortex manner to assist in mixing the two liquid medicines.

[0041] like Fig.10 and Fig.11 As shown, it also includes a latch tooth 401, which is fixedly connected to the first connecting frame 201, and a fixing frame 402 is fixedly connected to the side of the housing 101 close to the latch tooth 401, and a first screw rod 403 is rotatably connected to the fixing frame 402, and a lifting block 404 is threadedly connected to the first screw rod 403, and the lifting block 404 is slidably connected to the fixing frame 402, and a latch block 405 is slidably connected to the side of the lifting block 404 close to the latch tooth 401, and the latch block 405 moves to one side to engage with the latch tooth 401, and a spring 406 is fixedly connected between the latch block 405 and the lifting block 404.

[0042] If the bellows 203 is quickly reset upward, the bellows 203 will quickly push all the medicine in the upper chamber of the shell 101 into the nasal cavity each time, causing great discomfort to the patient, especially the elderly and children. Therefore, in this case, it is necessary to slow down the speed of pushing out the medicine so that the medicine can be pushed out slowly and in small quantities. The specific adjustment operation is as follows: before loosening the rotating rod 202, first rotate the first screw rod 403 so that the lifting block 404 drives the clamping block 405 to move to the clamping tooth 401 through the spring 406. In this way, after loosening the rotating rod 202, the first connecting frame 201 drives the clamping tooth 401 to move upward. Under the elastic resistance formed by the spring 406 and the clamping block 405, the clamping tooth 401 slowly moves upward, thereby causing the first connecting frame 201 to slowly move upward, and then causing the bellows 203 to slowly move upward, and then causing the medicine to be slowly pushed out in small quantities, avoiding discomfort to the patient.

[0043] Embodiment 3: Based on embodiment 2, Fig.11 As shown, a handle 501 is also included. The handle 501 is rotatably connected to the right side of the housing 101 . The handle 501 is fixed to the rotating rod 202 . A connecting rod 502 is rotatably connected between the handle 501 and the lifting frame 108 .

[0044] Since each time the medicine is sprayed, it is necessary to push up the lifting frame 108 and rotate the rotating rod 202 at the same time, which is inconvenient and laborious to operate. Therefore, by pressing the handle 501 toward the side close to the shell 101, the lifting frame 108 is driven to move upward through the connecting rod 502 by pressing the handle 501, and the rotating rod 202 is driven to rotate at the same time, which is simple, convenient and labor-saving to operate.

[0045] like Fig.11As shown, it also includes a rotating block 601, which is rotatably connected to the right side of the shell 101, a second screw 602 is fixedly connected to the rotating block 601, and the second screw 602 is threadedly connected to a sliding block 603, the sliding block 603 is slidably connected to the shell 101, a blocking groove is opened on the front side of the sliding block 603, and the blocking groove is composed of an oblique groove on the lower side and a straight groove on the upper side, and a blocking block 604 is fixedly connected to the upper part of the handle 501, and the blocking block 604 can be rotated toward the side close to the shell 101 to contact the blocking groove of the sliding block 603.

[0046] By adjusting the rotatable angle of the handle 501, the rotatable angle of the rotating rod 202 can be adjusted, thereby adjusting the amount of medicine sprayed each time. The specific operation of adjusting the rotatable angle of the handle 501 is as follows: when it is necessary to reduce the amount of medicine sprayed each time, control the rotation 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 contacts the blocking groove of the sliding block 603 when the handle 501 rotates, thereby making the rotatable angle of the handle 501 smaller, and then making the amount of medicine sprayed each time smaller, conversely, the amount of medicine sprayed each time is larger.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
