Description

Technical Field

[0001] This utility model relates to the field of aerosol storage tank technology, specifically an aerosol storage tank with a replacement structure. Background Technology

[0002] A spacer is an auxiliary tool for metered-dose inhaler therapy. The mist from the metered-dose inhaler is fully mixed with air in the spacer before being inhaled by the patient. Using a spacer can solve the problem of asynchronous inhalation and inhalation. Furthermore, because the patient can inhale several times, the amount of medication inhaled into the airways and lung tissue is significantly increased compared to using a metered-dose inhaler alone.

[0003] Traditional mist storage tanks are not easily disassembled, and the air intake hoods on them are not easy to replace. Therefore, it is not convenient for staff to disinfect them after long-term use, which reduces the practicality of the mist storage tanks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aerosol storage can with a replaceable structure, which solves the problem mentioned in the background art that traditional storage cans cannot be easily disassembled and the air intake cover on the storage can is not easy to replace. Therefore, it is not convenient for staff to disinfect the storage can after long-term use, which reduces the practicality of the storage can.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aerosol storage can with a replacement structure, comprising a can body, a threaded end at the top of the can body, a top cover at the top of the can body, the top cover being fixed to the can body via the threaded end, a connecting tube at the top of the can body, a face mask on the connecting tube, a fastening ring between the face mask and the connecting tube, a bottom cover at the bottom of the can body, a connecting end fixedly installed on the bottom cover, a protrusion on the bottom cover, the bottom cover being connected to the can body via the connecting end, and a pressurized metered aerosol being disposed at the bottom of the bottom cover.

[0006] Using the above technical solution, the threaded end at the top of the canister facilitates the connection between the top cover and the canister. The mask on the top cover allows the patient to inhale the aerosol. A fastening ring is provided between the mask and the connecting tube, so when the staff removes the fastening ring, the mask and the top cover can be easily removed, making it easy for the staff to replace and disinfect the mask later, thus preventing cross-infection.

[0007] Preferably, a connecting cylinder is provided on the front surface of the tank near the bottom, a mounting bracket is fixedly installed at the front end of the connecting cylinder, a connecting rod passes through the mounting bracket, and a mounting block is fixedly installed at the outer end of the connecting rod.

[0008] Using the above technical solution, by pulling the mounting block, the mounting block causes the connecting rod to move outward. Then the spring will contract, and the sealing block installed at the bottom of the limiting plate at the bottom of the connecting rod will be drawn out from the connecting cylinder, allowing air to enter the canister. This facilitates the user to fully inhale the aerosol inside the mist canister, avoids stuffiness during use, and improves the utilization rate of the drug inside the mist canister.

[0009] Preferably, a limiting plate is fixedly installed at the bottom of the connecting rod, a sealing block is fixedly installed at the inner end of the limiting plate, a spring is fixedly installed on the limiting plate, and the other end of the spring is connected to the mounting bracket.

[0010] By adopting the above technical solution, the spring drives the limiting plate to reset by loosening the mounting block, thereby allowing the sealing block installed inside the limiting plate to be inserted into the connecting cylinder, thus sealing the connecting cylinder.

[0011] Preferably, the sealing block is made of rubber, and the diameter of the sealing block is the same as the diameter of the opening inside the connecting cylinder.

[0012] By adopting the above technical solution, and using rubber material for the sealing block, a good sealing effect can be achieved.

[0013] Preferably, the top cover has a threaded groove, which makes it easy to fix the top cover to the threaded end at the top of the can, and the bottom of the can has a threaded groove, which makes it easy to connect to the connecting end on the bottom cover.

[0014] By adopting the above technical solution, a bottom cover is provided at the bottom of the tank, and a connecting end is provided on the bottom cover. The connecting end and the threaded groove inside the tank engage with each other, so the bottom cover can be kept stable with the tank. Furthermore, because there are protrusions on the bottom cover, the bottom cover is easy to disassemble.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This aerosol storage canister with a replaceable structure allows the top cover to be easily connected to the canister body via a threaded end. The face mask on the top cover allows patients to inhale the aerosol. A fastening ring is provided between the face mask and the connecting tube, so the face mask and top cover can be easily removed by the staff after the fastening ring is removed. This facilitates the subsequent replacement and disinfection of the face mask, thereby preventing cross-infection.

[0017] 2. This aerosol storage canister with a replacement structure allows the connecting rod to move outward by pulling the mounting block. The spring then contracts, causing the sealing block at the bottom of the limiting plate on the connecting rod to be drawn out of the connecting cylinder. This allows air to enter the canister, facilitating the user's full inhalation of the aerosol inside, preventing stuffiness during use, and improving the utilization rate of the medication inside the storage canister.

[0026] Working principle: The threaded end 2 at the top of the canister 1 facilitates the connection between the top cover 3 and the canister 1. The mask 5 on the top cover 3 allows the patient to inhale the aerosol. A fastening ring 6 is provided between the mask 5 and the connecting tube 4. Therefore, when the staff removes the fastening ring 6, the mask 5 and the top cover 3 can be easily removed, making it easy for the staff to replace and disinfect the mask 5 later, thus preventing cross-infection. The bottom of the canister 1 is provided with a bottom cover 17, and the bottom cover 17 is provided with a connecting end 7. The connecting end 7 and the threaded groove inside the canister 1 are interlocked, thus ensuring the stability of the bottom cover 17 and the canister 1. The protrusion 8 on the bottom cover 17 makes the disassembly of the bottom cover 17 relatively simple. After the bottom cover 17 and the top cover 3 are removed, the staff can disinfect the aerosol canister.

[0027] Example 2:

[0028] Referring to Figures 1-4, an aerosol storage can with a replacement structure is described. A connecting cylinder 10 is located near the bottom of the front surface of the can body 1. A mounting frame 11 is fixedly installed at the front end of the connecting cylinder 10. A connecting rod 12 passes through the mounting frame 11.
