Description

Technical Field

[0001] This invention belongs to the field of medical device technology research, specifically relating to a nebulizer bottle for the treatment of bronchial asthma. Background Technology

[0002] Asthma is a heterogeneous disease characterized by chronic airway inflammation and airway hyperresponsiveness. Asthma attacks are extremely painful for patients. The most effective way to reduce suffering is usually to immediately infuse asthma medication into the mouth and throat, delivering the medication directly to the trachea. Therefore, nebulizers are an important medical device for treating asthma. However, current nebulizers require pressing the nozzle of the nebulizer canister to administer medication, but they do not provide a precise dosage.

[0003] Patent CN206880917U discloses a drug delivery device for treating bronchial asthma, comprising a shell, a drug delivery box, a drug delivery container, a spring, and a push rod extending through the drug delivery container. The push rod also includes a movable stop, a finger pressure handle, a spring limiting block, and a piston limiting block. When a patient uses this drug delivery device, they simply press the finger pressure handle. The handle, through the push rod and the movable stop, sprays the medication loaded in the quantitative drug delivery container directly into the patient's mouth via a nebulizer. After the patient releases the finger pressure handle, the push rod, under the rebound of the spring, moves the movable stop upward again, refilling the quantitative drug delivery container with the medication from the drug delivery box, thus achieving the purpose of quantitative drug delivery with each press.

[0004] However, in the above technical solution, the liquid in the dosing tank decreases continuously after repeated use, causing the pressure difference between the dosing tank and the dosing container to gradually decrease. Therefore, after use, the pressure in the dosing tank is insufficient to draw the liquid into the dosing container. When used again, the liquid cannot be effectively sprayed out. Therefore, it is necessary to press the button multiple times to increase the pressure in the dosing tank, so as to increase the pressure difference between the dosing tank and the dosing container, and then draw the liquid into the dosing container until the liquid is sprayed out. Therefore, in emergency medication, the liquid cannot be effectively sprayed out after one press. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem that existing drug delivery devices cannot effectively dispense medication after multiple uses with a single press. The technical approach of this invention is to add a drug storage bottle pressurizing mechanism and a dispensing cylinder between the spraying lever and the drug storage bottle. During use, while the spraying lever sprays a measured amount of medication from the dispensing cylinder through the nozzle, the spraying lever pressurizes the drug storage bottle multiple times through the drug storage bottle pressurizing mechanism, so that sufficient medication is drawn from the drug storage bottle into the dispensing cylinder. In this way, in emergency medication use, it can be ensured that the patient receives a sufficient and measured amount of medication with a single press.

[0006] Based on the above technical concept, the technical solution adopted by this invention is as follows: A nebulizer bottle for treating bronchial asthma includes: a drug reservoir, a nozzle, and a spraying lever; the nozzle is disposed at the upper end of the drug reservoir and connected to the spraying lever; it also includes: a drug reservoir pressurization mechanism and a spray tube; the spray tube is disposed between the nozzle and the drug reservoir. The spraying pressing rod is connected to the spraying cylinder and the storage bottle respectively through the storage bottle pressurization mechanism. It is used to spray a metered amount of medicine from the spraying cylinder from the nozzle, and at the same time, the storage bottle pressurization mechanism pressurizes the storage bottle multiple times to input the metered amount of medicine from the storage bottle into the spraying cylinder.

[0007] For further refinement of the above technical solution, preferably, the medicine storage bottle pressurization mechanism includes a pressurization drive unit and a pressurization cylinder; The pressurization drive unit is disposed inside the pressurization cylinder, and the pressurization drive unit passes through the pressurization cylinder and is connected to the spraying pressing rod; The pressurizing cylinder is connected to both the spray nozzle and the medicine storage bottle.

[0008] The above technical solution is further specified to include a first piston and a second piston; The spraying pressing rod is set at the same horizontal line as the second piston, and is used to control the second piston to spray a metered amount of medicine from the nozzle in the spraying cylinder; The spraying press rod is perpendicular to the first piston and is used to control the first piston to pressurize the medicine storage bottle multiple times through the pressurization drive unit while spraying a metered amount of medicine from the nozzle, so as to input the metered amount of medicine in the medicine storage bottle into the spraying cylinder.

[0009] Furthermore, in the above technical solution, the booster drive unit includes a drive gear set, a push rod, and a rotating cylinder; the drive gear set is sleeved on the rotating cylinder. The push rod passes through the rotating cylinder and is connected to the second piston; The drive gear set is connected to the first piston.

[0010] For the first piston in the above technical solution, the first piston further includes a first piston body and a linear rack disposed on the first piston body; The drive gear set is meshed with the linear rack.

[0011] Furthermore, in the above technical solution, the drive gear set includes a direction control gear and a drive gear; the direction control gear is fixedly connected to the drive gear.

[0012] Furthermore, in the above technical solution, the second piston is provided with a return spring at the end of the second piston away from the booster drive unit.

[0013] Furthermore, in the above technical solution, the pressure booster cylinder is provided with an air outlet at the connection between the pressure booster cylinder and the medicine storage bottle; and an air inlet connected to the outside is provided on the side of the pressure booster cylinder. The air inlet and the air outlet are the same, and both are equipped with a one-way ball valve inside.

[0014] This invention also provides a method of using a nebulizer bottle for the treatment of bronchial asthma. After pressing the spraying lever once, the spraying lever controls the second piston to move towards the side of the spraying cylinder via the push rod, so that the liquid medicine in the spraying cylinder is sprayed out from the nozzle. At the same time, the spraying lever drives the rotating cylinder to rotate via the push rod, and then the rotating cylinder drives the first piston to move up and down reciprocally via the drive gear set. Atmospheric pressure enters the medicine storage bottle multiple times to increase the internal pressure of the medicine storage bottle, so that the liquid medicine in the medicine storage bottle enters the spraying cylinder.

[0015] Further specifying the method of using the above-mentioned nebulizer bottle for the treatment of bronchial asthma, preferably, after releasing the spraying press lever, the reset spring drives the push rod to move in the opposite direction, and the push rod drives the first piston to move up and down again through the drive gear set, so that atmospheric pressure enters the storage bottle multiple times to increase the internal pressure of the storage bottle, and draws the liquid medicine in the storage bottle into the spraying cylinder again.

[0016] The beneficial effects of this invention are: This invention adds a medicine bottle pressurization mechanism and a spray nozzle between the pressing rod and the medicine bottle. In use, the pressing rod sprays the medicine from the nozzle of the spray nozzle, while the driving gear set in the medicine bottle pressurization mechanism controls the first piston to move up and down repeatedly. This draws in atmospheric pressure from the air inlet and inputs it into the medicine bottle through the air outlet, increasing the pressure inside the medicine bottle. This ensures that enough medicine is drawn from the medicine bottle into the spray nozzle, so that in emergency medication use, the patient can receive a sufficient and measured amount of medicine with just one press.

[0017] In addition, after the spraying press lever is released, the reset spring on one side of the second piston drives the push rod back to the initial position. Therefore, the push rod drives the drive gear set to rotate in the opposite direction, which in turn drives the first piston to move up and down again to increase the pressure in the storage bottle and draw the liquid medicine in the storage bottle into the spraying cylinder again, further ensuring that enough liquid medicine in the storage bottle is drawn into the spraying cylinder.

[0018] Furthermore, the number of times the first piston reciprocates up and down can be controlled by controlling the number of revolutions of the track inside the rotating cylinder connected to the drive gear set. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example

[0025] like Figure 1-15 As shown, this invention provides a nebulizer bottle for the treatment of bronchial asthma, comprising: a drug storage bottle pressurization mechanism 1, a spray cylinder 2, a drug storage bottle 3, a nozzle 4, and a spraying pressure rod 5.

[0026] The spray nozzle 2 is positioned above the medicine storage bottle 3, and the spray nozzle 2 and the medicine storage bottle 3 are interconnected by a one-way suction tube 15 so that the medicine in the medicine storage bottle 3 can enter the spray nozzle 2.

[0027] Specifically, the one-way suction tube 15 is installed in the medicine storage bottle 3, and a one-way ball valve is provided inside the opening connecting the spray cylinder 2 and the medicine storage bottle 3. When the medicine in the medicine storage bottle 3 enters the spray cylinder 2, the one-way ball valve in the one-way suction tube 15 opens. When the pressurization of the medicine storage bottle 3 stops, the one-way ball valve in the one-way suction tube 15 closes, so that the medicine in the spray cylinder 2 cannot fall back into the medicine storage bottle 3 due to gravity.

[0028] Nozzle 4 is positioned at the upper end of the spray cylinder 2 so that the liquid medicine in the spray cylinder 2 can be sprayed out from nozzle 4.

[0029] The medicine bottle pressurization mechanism 1 includes a pressurization drive unit 11 and a pressurization cylinder 12.

[0030] like Figure 2 As shown, the booster cylinder 12 is an "L"-shaped cylindrical structure, with one end connected to the spray nozzle 2 and the other end connected to the medicine storage bottle 3 through the air outlet 8. Inside the booster cylinder 12, a second piston 7 is horizontally connected to the booster drive unit 11, and inside the booster cylinder 12, a first piston 6 is vertically connected to the booster drive unit 11.

[0031] The pressurization drive unit 11 is located inside the pressurization cylinder 12 and passes through the side of the pressurization cylinder 12 to connect with the spraying press lever 5. During use, the patient presses the spraying press lever 5 once. Simultaneously, the spraying press lever 5 sprays the liquid medicine from the nozzle 4 into the spraying cylinder 2. At the same time, the medicine storage bottle pressurization mechanism 1 repeatedly pressurizes the inside of the medicine storage bottle 3, thus inputting the liquid medicine from the medicine storage bottle 3 into the spraying cylinder 2. At this time, the one-way ball valve in the one-way suction tube 15 opens. After the pressurization of the medicine storage bottle 3 ends, the one-way ball valve in the one-way suction tube 15 closes, preventing the liquid medicine in the spraying cylinder 2 from falling back into the medicine storage bottle 3 under gravity.

[0032] The booster drive unit 11 includes a drive gear set 11a, a push rod 11b, and a rotating cylinder 11c. The drive gear set 11a is sleeved on the rotating cylinder 11c.

[0033] like Figure 6 and 11 As shown, one end of the push rod 11b passes through the rotating cylinder 11c and connects to the second piston 7, while the other end is connected to the spraying pressing rod 5 via a pin. The second piston 7 and the spraying pressing rod 5 are horizontally positioned so that when the spraying pressing rod 5 presses the push rod 11b to move linearly to one side of the spraying cylinder 2, the second piston 7, located near the end of the push rod 11b close to the spraying cylinder 2, moves towards the spraying cylinder 2, increasing the internal pressure of the spraying cylinder 2, and thus causing the liquid medicine in the spraying cylinder 2 to be sprayed out from the nozzle 4. Since the size of the cavity between the spraying cylinder 2 and the second piston 7 is limited by the return spring 13, the second piston 7 can only compress a certain space to spray out a measured amount of liquid medicine from the spraying cylinder 2.

[0034] Among them, a return spring 13 is provided on the side of the second piston 7 away from the push rod 11b; correspondingly, as Figure 11 As shown, a locking block is provided at the connection between the pressure cylinder 12 and the spray cylinder 2 to lock the return spring 13 in the spray cylinder 2 and prevent the return spring 13 from falling off. Specifically, during the process of the second piston 7 moving towards the spray cylinder 2, the return spring 13 is squeezed at the connection between the pressure cylinder 12 and the spray cylinder 2. At this time, the internal pressure of the spray cylinder 2 increases, causing the liquid medicine in the spray cylinder 2 to be sprayed out from the nozzle 4. After the patient releases the spraying press rod 5, the return spring 13 returns to its initial state, thereby driving the second piston 7 and the push rod 11b to move away from the spray cylinder 2, so that the push rod 11b returns to its initial position.

[0035] Furthermore, such as Figure 3 As shown, the upper end of the spraying lever 5 is rotatably connected to the pressurizing cylinder 12 via a rotating rod. Thus, during use, the upper end of the spraying lever 5 is fixed to the pressurizing cylinder 12 so that the patient can press the spraying lever 5, causing the spraying lever 5 to push the push rod 11b to one side of the spraying cylinder 2.

[0036] Not only that, such as Figure 7 As shown, multiple sliders 11d are provided on the part where the push rod 11b is sleeved with the rotating cylinder 11c. Specifically, the push rod 11b is a stepped connecting rod that is narrower at the front and wider at the back. Its narrow end is connected to the second piston 7, and its wide end is connected to the spraying pressing rod 5. The sliders 11d are arranged on its wide connecting rod.

[0037] like Figure 8 As shown, the inner wall of the rotating cylinder 11c is provided with a threaded track.

[0038] Specifically, the number of orbital rotations on the inner wall of the rotating cylinder 11c determines the number of rotations of the drive gear set 11a, which in turn determines the number of reciprocating motions of the linear rack 62. For example, if the number of orbital rotations is 1, then during one press of the spraying push rod 5, the linear rack 62 performs two linear motions, one up and one down, which constitute a set of reciprocating motions. The upward linear motion pressurizes the pressurizing cylinder 12, and the downward linear motion pressurizes the medicine storage bottle 3, thereby filling the medicine storage bottle 3 into the spraying cylinder 2. During the release of the spraying push rod 5, similarly, the linear rack 62, under the action of the rotating cylinder 11c, performs another set of reciprocating motions, once again filling the medicine storage bottle 3 into the spraying cylinder 2.

[0039] The embodiment of the present invention is illustrated by taking the case where the inner wall of the rotating cylinder 11c is provided with three threaded tracks, that is, the medicine storage bottle 3 is pressurized six times during a set of pressing and releasing the spraying press rod 5.

[0040] The slider 11d is mounted on a track on the inner wall of the rotating cylinder 11c. Thus, when the push rod 11b drives the second piston 7 to move linearly, the slider 11d drives the rotating cylinder 11c to rotate under the action of the push rod 11b.

[0041] Specifically, the rotating cylinder 11c is sleeved on the end of the push rod 11b that has the slider 11d, and the other end of the push rod 11b is connected to the spraying pressing rod 5 by a pin.

[0042] The drive gear set 11a includes three drive gears 11a-2 and two direction control gears 11a-1.

[0043] The three drive gears 11a-2 are arranged linearly around the straight rack 62, and the three drive gears 11a-2 mesh with each other; the drive gear in the middle has a through hole in the center so that the rotating cylinder 11c can pass through, and the drive gear in the middle is fixedly connected to the rotating cylinder 11c.

[0044] A fixing block 14 is provided on the side of the drive gear located in the middle near the spray cylinder 2. The fixing block 14 is horizontally coaxial with the push rod 11b and is used to connect with the first piston 6. The drive gear located in the middle can be fixedly connected to the rotating cylinder 11c in an integral connection or a pin connection, etc.

[0045] The fixing block 14 is sleeved on the rotating cylinder 11c and rotatably connected to the rotating cylinder 11c. In this way, when in use, the rotation of the rotating cylinder 11c will not drive the fixing block 41 to rotate, thus ensuring that the linear rack 62 remains vertical.

[0046] Two directional control gears 11a-1 are fixedly connected to the drive wheels 11a-2 on both sides, and the two directional control gears 11a-1 have the same structure and orientation, and both directional control gears 11a-1 are connected to the first piston 6. Specifically, the directional control gears 11a-1 have a sector-shaped structure.

[0047] The longer the arc length of the direction control gear 11a-1, the longer the linear movement distance of the first piston 6.

[0048] like Figure 15 As shown, the first piston 6 includes a first piston body 61 and a linear rack 62; wherein the linear rack 62 is disposed above the first piston body 61. The first piston body 61 is perpendicular to the spraying pressing rod 5.

[0049] Specifically, such as Figure 9 and 15 As shown, the linear rack 62 has a slide at its center for holding the fixing block 14 in place, and the linear rack 62 moves linearly in its vertical direction under the restriction of the fixing block 14.

[0050] The linear rack 62 is meshed with both directional control gears 11a-1 so that the two control gears 11a-1 control the linear motion direction of the linear rack 62 in the vertical direction.

[0051] In use, when the push rod 11b moves to one side of the spray cylinder 2 under the action of the spraying pressing rod 5, the slider 11d set on the push rod 11b moves linearly with the push rod 11b, so that the slider 11d moves on the track on the inner wall of the rotating cylinder 11c, so that the rotating cylinder 11c rotates under the action of the slider 11d, and then the rotating cylinder 11c drives the drive gear located in the middle to rotate, and the drive gear located in the middle drives the drive gears located on both sides to rotate, so that the direction control gear 11a-1 set on the drive gears on both sides rotates with the drive gear 11a-2.

[0052] Since the two directional control gears 11a-1 are oriented in the same direction, during one rotation cycle of the drive gear 11a-2, after one directional control gear 11a-1 controls the linear rack 62 to move downward, the other directional control gear 11a-1 controls the linear rack 62 to move upward. During the next rotation cycle of the drive gear 11a-2, the two directional control gears 11a-1 control the linear rack 62 to perform a set of reciprocating motions. This cycle is repeated to achieve multiple pressurization of the medicine storage bottle 3, thereby drawing the liquid medicine from the medicine storage bottle 3 into the spray nozzle 2.

[0053] Similarly, after releasing the press lever 5 for spraying, the reset spring drives the push rod 11b to move away from the spray cylinder 2. At this time, the slider 11d on the push rod 11b drives the rotating cylinder 11c to rotate in the opposite direction. The rotating cylinder 11c drives the drive gear set 11a to rotate in the opposite direction, which pressurizes the medicine storage bottle 3 multiple times and draws the medicine liquid in the medicine storage bottle 3 into the spray cylinder 2 again.

[0054] A pressurizing chamber is formed between the lower part of the first piston body 61 and the pressurizing cylinder 12. This pressurizing chamber has an air inlet 9 communicating with the outside on its side, and an air outlet 8 communicating with the medicine storage bottle 3 at its bottom. The air outlet 8 and the air inlet 9 have the same structure, and both are equipped with a one-way ball valve 10 inside. Figure 12 As shown, the present invention is illustrated using the air outlet 8 as an example.

[0055] like Figure 1 As shown, the present invention is illustrated by taking the case where the side of the pressurization chamber has three air inlets 9 as an example.

[0056] When in use, the first piston 6 moves downward. At this time, the one-way ball valve in the air outlet 8 moves downward under pressure, and the air outlet 8 opens. At the same time, the air inlet 9 moves outward under air pressure, and the air inlet 9 closes, so that the pressure in the pressurization chamber is squeezed from the air outlet 8 into the medicine storage bottle 3, thereby increasing the internal pressure of the medicine storage bottle 3. When the first piston 6 moves upward, the one-way ball valve in the air inlet 9 moves inward under the action of air pressure. At this time, the air inlet 9 opens, and the external atmospheric pressure enters the pressurization chamber. At this time, the one-way ball valve in the air outlet 8 moves upward under the action of atmospheric pressure, and the air outlet 8 closes, thereby increasing the internal pressure of the pressurization chamber. In this way, after the first piston 6 moves up and down repeatedly, the air pressure in the pressurization chamber can be squeezed into the medicine storage bottle 3 multiple times, thereby increasing the pressure in the medicine storage bottle 3 multiple times, and then the medicine liquid in the medicine storage bottle 3 enters the spray tube 2 from the one-way suction tube 15.

[0057] Taking the method of pressurizing the spray lever 5 six times in a single press as an example, the usage process of the nebulizer bottle for treating bronchial asthma provided in this embodiment of the invention is as follows: After the patient presses the spraying lever 5, the spraying lever 5 pushes the push rod 11b to one side of the spraying cylinder 2, thereby pushing the second piston 7 located at one end of the push rod 11b to one side of the spraying cylinder 2, so that the metered amount of medicine in the spraying cylinder 2 is sprayed out through the nozzle 4.

[0058] During the process of the push rod 11b moving to one side of the spray cylinder 2, the push rod 11b drives the rotating cylinder 11c to rotate through the slider 11d, which in turn drives the drive gear 11a-2 to rotate. The drive gear 11a-2 then drives the direction control gear 11a-1 to rotate. In the first rotation cycle of the drive gear 11a-2, one direction control gear 11a-1 drives the linear rack 62 to move downward, and the other direction control gear 11a-1 drives the linear rack 62 to move upward. This cycle repeats, and the drive gear set 11a drives the first piston body 61 to perform three sets of reciprocating motions through the linear rack 62, which pressurizes the inside of the medicine storage bottle 3 three times. This allows the medicine storage bottle 3 to be pressurized three times while the patient presses the spray button 5 to spray the metered amount of medicine from the nozzle 4 into the spray cylinder 2, thereby squeezing the medicine from the medicine storage bottle 3 into the spray cylinder 2.

[0059] After the patient releases the spraying lever 5, the reset spring 13 returns to its initial state. Therefore, the reset spring 13 drives the push rod 11b to move away from the spraying cylinder 2. At this time, the slider 11d on the push rod 11b drives the rotating cylinder 11c to rotate in the opposite direction. In turn, the rotating cylinder 11c drives the drive gear 11a-2 to rotate in the opposite direction. Similarly, within one rotation cycle of the drive gear 11a-2, the linear rack 62 performs a set of reciprocating motions. This cycle causes the first piston body 61 to pressurize the medicine storage bottle 3 three more times under the drive of the linear rack 62, and draw the medicine liquid in the medicine storage bottle 3 into the spraying cylinder 2 again, further ensuring that enough medicine liquid is filled into the spraying cylinder 2 from the medicine storage bottle 3.
