Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a respirator for asthma. Background Art

[0002] Asthma respirators generally include dry powder inhalers, nebulizer inhalers, and push-in inhalers. Traditionally, the drug is sprayed out by pressing, and the drug is sprayed out by human force. However, the pressing force is different for different people, which will result in different amounts of drug sprayed out. The push-in inhalers on the market cannot guarantee that the drug is pressed and sprayed out while inhaling the drug, that is, it is impossible to achieve hand-mouth consistency, resulting in most of the drug sprayed out during the pressing process being directly inhaled into the patient's mouth and unable to reach the patient's lungs, causing difficulty in breathing and poor treatment effect. Existing asthma respirators are mechanically pressed with preset pressure, which alleviates the situation where some vulnerable groups with low grip strength and pressing force cannot effectively press and spray the drug.

[0003] For example, the announcement with publication number CN115105695B discloses an asthma respirator and a method for using the asthma respirator, the asthma respirator comprising: a shell having a mounting cavity, a mounting hole being provided on the top thereof, and a medicine inhalation nozzle being provided on the bottom thereof; a push mechanism comprising a button, a push seat and a pre-compression spring, the button being arranged in the mounting hole, the push seat being arranged in the mounting cavity, a locking portion being provided on the push seat, and the pre-compression spring being arranged between the button and the push seat; a locking member being movably arranged on the button, the locking member being lockable to the locking portion to connect the button and the push seat; when the locking member is locked to the locking portion, the pre-compression spring is compressed; an unlocking mechanism comprising an unlocking member, the unlocking member being movably arranged on the push seat; when the patient inhales medicine from the medicine inhalation nozzle, the unlocking member can be driven to unlock the locking member from the locking portion.

[0004] Although the above-mentioned asthma respirator solves the problem of inconsistent hand and mouth when the patient inhales the medicine, when the patient inhales the medicine, the locking part must first be unlocked by the suction generated by the inhalation. During this process, the patient's inhalation process is nearing the end, the suction force is reduced, and the medicine has just been sprayed out. The amount that the patient can inhale is limited. Therefore, the patient inhales a small amount each time, which is not only wasteful, but also easily leads to blockage of the spray port. Summary of the invention

[0035] like Figures 1 to 12 As shown, an embodiment of the present invention provides a respirator for asthma, including a body, a power storage mechanism, a trigger mechanism and a transmission mechanism. A first cavity 104 for placing a medicine bottle 406 is provided in the body, a medicine suction nozzle 105 is provided at the bottom of the body, and a second cavity 106 is provided at the top of the body. The line connecting the second cavity 106 and the first cavity 104 extends in the body in a vertical direction. The power storage mechanism is arranged in the second cavity 106, and the power storage mechanism can accumulate energy that allows the medicine bottle 406 to slide in the first cavity 104 in the vertical direction; the trigger mechanism includes an airbag 201, a first airway, a first baffle, a second airway and a second baffle. The airbag 201 is arranged on the medicine suction nozzle 105. , the patient can bite the airbag 201, the first airway is opened in the body, and the first airway is connected to the airbag 201, the first baffle is slidably arranged in the first channel 202, the second airway is opened in the body, and one end of the second airway passes through the suction nozzle 105 and is connected to the patient's mouth, and the second baffle is slidably arranged in the second channel 204; the transmission mechanism includes a paddle 401, and an installation cavity 402 is opened on the body, and the paddle 401 is slidably arranged in the installation cavity 402. In the sliding direction of the paddle 401, the first baffle and the second baffle are respectively located on both sides of the paddle 401, and the first baffle and the second baffle can both contact with the paddle 401, and the paddle 401 is connected to the power storage mechanism.

[0036] When the patient squeezes the airbag 201 with his mouth, the force storage mechanism completes energy storage in advance, the first baffle plate is out of contact with the paddle plate 401, and the paddle plate 401 can rotate in the installation cavity 402; when the patient's mouth is isolated from the outside world and the patient blows gas into the second airway, the second baffle plate slides in the second airway and pushes the paddle plate 401 toward the first baffle plate, and the force storage mechanism releases energy.

[0037] By cooperating with the slider 203 and the paddle 401, when the patient does not squeeze the airbag 201, the paddle 401 will not overcome the obstruction of the slider 203 and rotate, thereby improving the safety of the asthma respirator. By setting a second airway, when the patient uses the asthma respirator, the patient can offset a series of transmission processes before the medicine bottle 406 releases the medicine through the exhalation process, so that the release of the medicine in the medicine bottle 406 can be synchronized with the patient's conversion from exhalation to inhalation as much as possible, thereby increasing the amount of medicine inhaled by the patient each time he inhales, so that the patient can be better treated.

[0038] In this embodiment, the first air channel includes a first channel 202 and a first slide 206, and the second air channel includes a second channel 204 and a second slide 207. One end of the first channel 202 and the second channel 204 respectively penetrates the drug suction nozzle 105, and the other end of the first channel 202 and the second channel 204 extends into the interior of the body. The first slide 206 and the second slide 207 are both arranged in the body, and the first slide 206 is respectively communicated with the first channel 202 and the installation cavity 402, and the second slide 207 is respectively communicated with the second channel 204 and the installation cavity 402. The first baffle includes a first piston 209 and a slider 203. The first piston 209 is slidably arranged in the first channel 202, and the slider 203 is slidably arranged in the first slide 206. The first piston 209 and the slider 203 are connected, and the first piston 209 and the airbag 201 are connected. A channel 202 is a closed channel, and the trigger mechanism also includes a first spring 208. The first spring 208 is arranged in the first slideway 206. The two ends of the first spring 208 are respectively connected to the body and the slider 203. The first spring 208 is used to reset the slider 203. The first spring 208 is located on the side of the slider 203 away from the first piston 209. The slider 203 is L-shaped and has two sides. The paddle 401 can contact the two sides of the slider 203. After the slider 203 moves and compresses the first spring 208, the paddle 401 is out of contact with one side of the slider 203, and the other side of the slider 203 moves to the rotation path of the paddle 401. There is a gap between the other side of the slider 203 and the paddle 401. When the paddle 401 rotates and approaches the slider 203, the paddle 401 will contact the slider 203 again.

[0039] The second baffle includes a second piston 210 and a push block 205. The second piston 210 is slidably disposed in the second channel 204. The second piston 210 divides the second channel 204 into two parts. The two parts of the second channel 204 are not connected to each other. The push block 205 is slidably disposed in the second slideway 207. The second piston 210 and the push block 205 are connected. The side of the slider 203 that contacts the dial plate 401 is an inclined surface. When the push block 205 moves away from the second channel 204, the dial plate 401 is pushed by the inclined surface around its own axis to the slider 203. When the patient squeezes the airbag 201, the volume of the airbag 201 decreases, and the gas in the airbag 201 enters the first channel 202. The gas in the first channel 202 pushes the first piston 209 to move. The first piston 209 moves the slider 203 and compresses the first spring 208. The paddle plate 401 has room to move in the first direction. At this time, the push block 205 can push the paddle plate 401 to rotate around its own axis through the inclined surface. The rotating paddle plate 401 can control the release of energy of the power storage mechanism.

[0040] In this embodiment, the main body includes an upper shell 101, a middle shell 102 and a lower shell 103, which are arranged in sequence from top to bottom in the vertical direction, and the middle shell 102 is connected to the upper shell 101 and the lower shell 103 respectively, and the upper shell 101, the middle shell 102 and the lower shell 103 are connected by bolts, which is convenient for disassembly, maintenance and installation of the medicine bottle 406; the medicine suction nozzle 105 is arranged on the lower shell 103, and a receiving groove 107 and a medicine channel 108 are opened on the lower shell 103, and a column 109 is provided in the receiving groove 107, and the receiving groove 107 is connected to the outside of the lower shell 103, and the medicine bottle 406 can be inserted into the column 109, and a nozzle is slidably provided on the column 109, and the nozzle and the medicine bottle 406 are always connected. , the medicine channel 108 is connected with the containing groove 107, and the medicine channel 108 passes through the medicine suction nozzle 105 and is located on the same surface of the medicine suction nozzle 105 as the second channel 204, the nozzle can slide in the medicine channel 108, and a second spring 111 is provided on the column 109, and the second spring 111 is used to push the nozzle to slide on the column 109. When the patient exhales, the gas flowing in the medicine channel 108 can push the nozzle to move in the medicine channel 108, and the nozzle compresses the second spring 111, so that the nozzle is separated from the medicine channel 108, and the flowing gas can enter the containing groove 107, and the surface of the nozzle is cleaned. When the patient inhales, the nozzle can move to the medicine channel 108 again under the action of the second spring 111, and the medicine coming out of the nozzle enters the patient's body through the medicine channel 108.

[0041] In this embodiment, the nozzle includes a straight column 112 and a frustum 113, a mounting hole 114 is provided on the column 109, the straight column 112 is slidably arranged in the mounting hole 114, a third cavity 115 is provided inside the straight column 112, a through groove 116 is provided on the peripheral surface of the straight column 112, the through groove 116 is connected to the third cavity 115, and the through groove 116 is always connected to the medicine bottle 406, the peripheral surface of the straight column 112 is in contact with the mounting hole 114, and the medicine bottle 406 is connected to the medicine bottle 406.

The straight column 112 will compress the second spring 111 during the patient's exhalation process. At this time, the medicine channel 108 and the receiving groove 107 will be connected. When the patient no longer blows into the medicine channel 108, the second spring 111 will recover at this time, and push the cone 113 to slide into the medicine channel 108 through the straight column 112, so that the medicine coming out of the through hole 110 will not enter the receiving groove 107. One end surface of the nozzle sliding on the medicine channel 108 is an arc surface. When the gas exhaled by the patient acts on the nozzle through the medicine channel 108, since the medicine bottle 406 is not in the medicine spraying stage at this time, the gas will not flow in the space between the nozzle and the medicine bottle 406. At this time, the gas in the medicine channel 108 can push the compressed second spring 111 to make the nozzle slide in the medicine channel 108. After sliding out of the medicine channel 108, the arc surface of the nozzle is in the receiving groove 107. At this time, the middle part of the arc surface of the nozzle is closer to the medicine channel 108 than its edge part. Under the flow of gas, impurities on the arc surface of the nozzle are more easily cleaned away.

[0048] The working principle and working method of a respirator for asthma provided in this embodiment are as follows:

[0049] First, install the medicine bottle 406 into the first cavity 104, and insert the medicine outlet end of the medicine bottle 406 into the column 109, and then install the upper shell 101 to the middle shell 102. At this time, the push plate 315 abuts against the support block 305, and the block is located in an edge of the card slot 306 extending along the vertical direction. Then press the button 301, and the button 301 pushes the card plate 308 to slide in the first slide groove 311 through the pressure plate 302. The pressure plate 302 approaches the abutment plate 303 and compresses the third spring 304 together with the abutment plate 303. When the card plate 308 slides in the first slide groove 311, it drives the latch pin 313 Move together, at this time the pin 313 is located in the second groove 316, and the pin 313 abuts against the ear 310 under the action of the fourth spring 314, and the button 301 continues to be pressed until the block on the upper shell 101 slides to the other side of the groove 306. At this time, the second groove 316 is connected to the second slide groove 312, and the pin 313 slides into the second slide groove 312 under the action of the fourth spring 314. Then rotate the button 301, the block slides to the other side of the groove 306, and the button 301 no longer moves in the vertical direction. At this time, the asthma respirator completes the energy storage before use.

[0050] When the patient needs to use the asthma respirator, he / she should first bite the inhalation nozzle 105 and the airbag 201 to isolate the oral cavity from the outside world. When the patient bites the airbag 201, the airbag 201 is deformed, and the gas inside the airbag 201 flows to the first channel 202. The gas in the first channel 202 pushes the first piston 209 to slide, and the first piston 209 pushes the slider 203 to compress the first spring 208. At the same time, the slider 203 is out of contact with the paddle 401. Then the patient exhales through his / her mouth, and the gas exhaled by the patient is discharged. The gas entering the medicine channel 108 pushes the nozzle to slide in the medicine channel 108 and compresses the second spring 111 until the nozzle is separated from the medicine channel 108, and the medicine channel 108 is connected with the receiving groove 107. The gas in the medicine channel 108 is discharged through the receiving groove 107. At the same time, the flowing gas cleans the surface of the nozzle through the surface of the nozzle. The gas entering the second channel 204 pushes the second piston 210 to slide in the second channel 204. The second piston 210 pushes the push block 205 to slide in the second slideway 207. The push block 205 pushes the dial plate 401 to rotate around its own rotation axis through its own inclined surface. The dial plate 401 slides in the installation cavity 402 and contacts the slider 203 again. After contacting the slider 203, the dial plate 401 stops moving. When the dial plate 401 rotates around the bracket 403, it drives the protrusion 405 to push the push plate 315 to move. The moving push plate 315 slides in the second slide groove 312 and abuts against the latch 313. 315 continues to slide and disengages from the support block 305, and then the push plate 315 pushes the latch 313 to slide out of the second slide groove 312, and the third spring 304 releases energy. The third spring 304 pushes the abutment plate 303 to approach the middle shell 102, and the abutment plate 303 pushes the medicine bottle 406 to slide in the first cavity 104. After sliding, the medicine bottle 406 starts to spray medicine. The medicine sprayed from the medicine bottle 406 enters the third cavity 115 through the through groove 116, and then enters the medicine channel 108 through the through hole 110, and is finally inhaled by the patient.

[0051] When the patient exhales and then inhales quickly, the nozzle is no longer subjected to thrust, and the second spring 111 recovers and pushes the nozzle to move in the mounting hole 114, and the nozzle slides into the medicine channel 108 again, and the medicine channel 108 is separated from the receiving groove 107. After the medicine in the medicine bottle 406 flows into the medicine channel 108, the patient can inhale the medicine into the body by inhaling.

[0052] After the medicine bottle 406 finishes spraying, the dial plate 401 is reset under the action of the seventh spring 404, and then the button 301 is rotated, the plate 303 is reset under the action of the sixth spring 318, and the plate 303 pushes the button 301 to move through the third spring 304, and the push plate 315 is reset under the action of the fifth spring 317 and is located above the support block 305 again.
