Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an atomization drug delivery device. Background Art

[0002] When treating chest diseases in children, it is often necessary to use a medical nebulizer, such as colds, fevers, coughs, asthma, rhinitis and other diseases. Nebulizer inhalation therapy is an important and effective treatment method for respiratory diseases. Specifically, the drug solution is injected into the nebulizer. After the nebulizer mechanism atomizes the drug solution and water into tiny particles, the drug solution is inhaled through breathing to prevent it from entering the human respiratory tract and lungs. Compared with injections, it has a painless and rapid treatment effect.

[0003] The piezoelectric ultrasonic nebulizers commonly used at present are all in the form of continuous atomization. The nebulizer cannot work intermittently according to the human breathing rhythm. During the atomization process, the drug solution is continuously atomized by the atomization mechanism and discharged from the equipment. When the patient receives atomization treatment, the atomized liquid will not be inhaled into the body during the exhalation phase. At this time, the atomized drug solution will spread in the surrounding environment and on the patient's skin and clothing, resulting in a waste of drug solution. At the same time, the skin on the face and chest of children is thinner than that of adults. The drugs attached to the skin can easily irritate this part of the skin, causing rashes, itching or other skin discomfort. Summary of the invention

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, by providing a push valve and a squeeze block, when the push valve is triggered, the push valve blocks the passage between the medicine liquid hopper and the hose, so that the medicine liquid cannot continue to enter the hose. At this time, because the triggering states of the push valve and the squeeze block are opposite, the squeeze block is not triggered, so that the medicine liquid in the hose enters the water pump along the medicine liquid pipe, and enters the atomizer to be atomized as the water pump extracts, mixes and transports. As the motor rotates, the fixed wheel and the rotating wheel no longer contact the triggering component of the push valve. At this time, the push valve opens, so that the medicine liquid hopper and the hose are connected. At the same time, the outer plate and the inner plate contact the squeeze block, so that The squeezing block squeezes the hose, so that the connection between the hose and the medicine liquid pipe is interrupted, so that the medicine flowing out of the medicine liquid bucket is accumulated in the hose. As the motor continues to rotate, the state of the pressing valve and the squeezing block is switched. At this time, the medicine in the hose flows into the medicine liquid pipe, and the medicine in the medicine liquid bucket will not continue to flow down, so that the device intermittently supplies medicine liquid to the nebulizer. By pre-adjusting the rhythm of supplying and stopping medicine supply to be the same as the patient's breathing rhythm, the device can only atomize water during the patient's exhalation stage, thereby reducing the waste of medicine liquid and avoiding irritation to the patient's skin after excessive medicine liquid adheres to it.

[0017] 2. Secondly, in the present invention, by setting the slider to a structure that can slide up and down, by adjusting the height of the slider, after adjusting the slider, the capacity of the upper half of the liquid medicine carrier formed by the squeezing block squeezing the hose is different, and different single drug supply amounts are adjusted according to different treatment needs. By setting the number of rotations of the motor, the device can inject a fixed amount of liquid medicine into the nebulizer, which can not only control the amount of medicine used for a single time, but also control the total amount of medicine used, thereby avoiding waste of liquid medicine and preventing patients from inhaling or getting stained with excessive liquid medicine, causing treatment problems.

[0018] 3. Finally, by setting the outer plate and the inner plate sliding on the rotating shaft, while driving the slider to move up and down, the linkage frame drives the outer plate and the inner plate to move up and down together, so that the relative height of the slider and the outer plate and the inner plate remains unchanged, so that the outer plate and the inner plate can always trigger the extrusion block, and at the same time, by setting the first arc groove and the third arc groove, the angle between the fixed wheel and the rotating wheel, the outer plate and the inner plate is changed by rotating the rotating wheel or the inner plate, so as to control the amount of medicine in a single triggering process when the motor speed remains unchanged, so as to more flexibly adjust the amount of medicine supplied at a single time and reduce the waste of medicine in the atomization process.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 7As shown, an embodiment of the present invention provides an atomization drug delivery device, including a shell 1, an adjustment door 2 is hingedly connected to the front side of the shell 1, an observation window 7 is opened on the adjustment door 2, an atomizer 3 is fixedly arranged inside the shell 1, and its top mist outlet passes through the top of the shell 1 and extends out, a bracket 20 is fixedly connected to the left inner side of the shell 1, a liquid medicine hopper 13 passing through the top surface of the shell 1 is fixedly connected, a pressing valve 14 is fixedly connected to the bottom of the liquid medicine hopper 13 through a bent pipe, a hose 15 is fixedly connected to the bottom of the pressing valve 14, the bottom of the hose 15 is fixedly sleeved in the bracket 20, a slider 16 is slidably sleeved on the outer side of the hose 15 through a mounting hole 26, a linkage frame 17 is fixedly connected to the side of the slider 16, a motor 21 located inside the bracket 20 is fixedly connected to the inner bottom surface of the shell 1, and the bracket 20 is fixedly connected to the inner bottom surface of the shell 1. A mounting plate 23 is rotatably installed inside, the output shaft of the motor 21 passes through the center of the mounting plate 23 and is fixedly connected with a coaxial rotating shaft 22, a fixed wheel 32 is fixedly sleeved on the rotating shaft 22, and a rotating wheel 33, an inner plate 25 and an outer plate 24 are sequentially slid downwardly sleeved on the rotating shaft 22, the top surfaces of the rotating wheel 33 and the inner plate 25 are provided with a first arc groove 36 that passes through, and the top surface of the outer plate 24 is provided with a third arc groove 38 that passes through, a first connecting column 34 is fixedly connected to the ground of the fixed wheel 32, and a second connecting column 35 is fixedly connected to the bottom surface of the rotating wheel 33, the bottom end of the first connecting column 34 passes through the first arc groove 36 and passes through the outer plate 24 and is fixedly connected to the top surface of the mounting plate 23, and the bottom end of the second connecting column 35 passes through the inner plate 25 and passes through the third arc groove 38 and is fixedly connected to the top surface of the mounting plate 23.

[0029] In the present invention, by setting the pressing valve 14 and the squeezing block 27, when the pressing valve 14 is triggered, the pressing valve 14 blocks the passage between the liquid medicine hopper 13 and the hose 15, so that the liquid medicine cannot continue to enter the hose 15. At this time, because the triggering states of the pressing valve 14 and the squeezing block 27 are opposite, the squeezing block 27 is not triggered, so that the liquid medicine in the hose 15 enters the water pump 12 along the liquid medicine pipe 18, and enters the atomizer 3 to be atomized as the water pump 12 extracts, mixes and transports. As the motor 21 rotates, the fixed wheel 32 and the rotating wheel 33 no longer contact the triggering component of the pressing valve 14. At this time, the pressing valve 14 is opened, so that the liquid medicine hopper 13 and the hose 15 are connected. At the same time, the outer plate 24 and the inner plate 2 5 contacts the squeezing block 27, so that the squeezing block 27 squeezes the hose 15, so that the connection between the hose 15 and the liquid medicine pipe 18 is interrupted, and then the liquid medicine flowing down from the liquid medicine bucket 13 is accumulated in the hose 15. As the motor 21 continues to rotate, the states of the pressing valve 14 and the squeezing block 27 are switched, and the liquid medicine in the hose 15 flows into the liquid medicine pipe 18, and the liquid medicine in the liquid medicine bucket 13 does not continue to flow down, so that the device intermittently supplies liquid medicine to the nebulizer 3. By pre-adjusting, the rhythm of supplying and stopping the supply of medicine is the same as the breathing rhythm of the patient, so that the device can only atomize water during the patient's exhalation link, thereby reducing the waste of liquid medicine and avoiding irritation to the patient's skin after excessive liquid medicine adheres to the patient's skin.

[0030] Secondly, in the present invention, the slider 16 is set to a structure that can slide up and down, and the height of the slider 16 is adjusted. After adjusting the slider 16, the capacity of the upper half of the liquid medicine carrier formed by the squeezing block 27 squeezing the hose 15 is different, and different single drug supply amounts are adjusted according to different treatment needs. By setting the number of rotations of the motor 21, the device can inject a fixed amount of liquid medicine into the nebulizer 3, which can not only control the amount of medicine used for a single time, but also control the total amount of medicine used, thereby avoiding waste of liquid medicine and avoiding problems in treatment caused by the patient inhaling or being stained with excessive liquid medicine.

[0031] Finally, by setting the outer plate 24 and the inner plate 25 sliding on the rotating shaft 22, while driving the slider 16 to move up and down, the linkage frame 17 drives the outer plate 24 and the inner plate 25 to move up and down together, so that the relative heights of the slider 16 and the outer plate 24 and the inner plate 25 remain unchanged, so that the outer plate 24 and the inner plate 25 can always trigger the extrusion block 27, and at the same time, by setting the first arc groove 36 and the third arc groove 38, the angle between the fixed wheel 32 and the rotating wheel 33, the outer plate 24 and the inner plate 25 is changed by rotating the rotating wheel 33 or the inner plate 25, so as to control the amount of medicine in a single triggering process when the speed of the motor 21 remains unchanged, so as to more flexibly adjust the amount of medicine supplied at a single time and reduce the waste of medicine during the atomization process.

[0032] Among them, the fixed wheel 32, the rotating wheel 33, the outer plate 24 and the inner plate 25 are all circular plates with notches, and the pressing valve 14 and the extrusion block 27 are triggered when the largest diameter part thereof contacts them. The triggering states of the pressing valve 14 and the extrusion block 27 are opposite. When the linkage frame 17 moves up and down, the outer plate 24 and the inner plate 25 move up and down with it. A plurality of first springs 28 are fixedly connected to the left side of the extrusion block 27. After the extrusion block 27 is pushed and the first spring 28 contracts, the extrusion block 27 squeezes the hose 15 and divides it into two upper and lower sections from this part.

[0033] After the squeezing block 27 is pushed by the outer plate 24 and the inner plate 25 to squeeze the hose 15, the upper half of the hose 15 is filled with the medicine flowing down from the medicine bucket 13. As the outer plate 24 and the inner plate 25 are no longer in contact with the squeezing block 27, the squeezing block 27 no longer squeezes the hose 15 under the action of the first spring 28. At this time, the medicine flows into the water pump 12 along the medicine pipe 18 below. While the medicine in the hose 15 flows down, the pressing valve 14 closes the passage between the medicine bucket 13 and the hose 15 to prevent the medicine in the medicine bucket 13 from flowing into the hose 15, causing the amount of medicine provided to the water pump 12 to increase.

[0034] Among them, a first slide groove 4 is opened on the left side of the shell 1, and the left end of the slider 16 is slidably connected in the first slide groove 4 and extends out of the shell 1. After the slider 16 slides up and down, the capacity of the upper and lower sections of the hose 15 separated by the extrusion block 27 changes. The symmetrical inner side surfaces of the first slide groove 4 are opened with grooves, and teeth 41 are fixedly connected therein. The two sides of the slider 16 located in the first slide groove 4 are slidably connected with inclined blocks 19, and a second spring 29 is elastically connected between the inclined block 19 and the slider 16. A symmetrical second slide groove 30 is opened on the left side of the slider 16, and a lever 31 passing through the second slide groove 30 is fixedly connected to the left side of the inclined block 19.

[0035] The setting of the slider 16 allows the user to adjust the amount of liquid medicine received in the hose 15 at a time according to actual needs, so as to provide the patient with a quantitative amount of liquid medicine during the patient's inhalation phase, thereby avoiding waste caused by providing too much liquid medicine and irritating the patient's skin.

[0036] By providing the inclined block 19 and the teeth 41 , the slider 16 can only move upward in one direction when the lever 31 is not pushed inward, thereby preventing the liquid medicine in the hose 15 from squeezing the slider 16 to slide down, causing excessive liquid medicine to accumulate in the hose 15 .

[0037] Among them, the inside of the shell 1 is fixedly connected to a water tank 11, and a water inlet 6 is opened on the top of the shell 1. When the regulating door 2 is closed, the front side of the water tank 11 abuts against the inner side of the regulating door 2. The inside of the shell 1 is fixedly connected to a water pump 12 located behind the water tank 11. The water pump 12 has two input ends and one output end. The bottom end of the hose 15 is fixedly connected to a liquid medicine pipe 18, and the other end of the liquid medicine pipe 18 is connected to one input end of the water pump 12, and the other input end of the water pump 12 is connected to the water tank 11. The output end of the water pump 12 is connected to the input port of the atomizer 3.

[0038] After the medicine liquid and water are pumped by the water pump 12, the two are mixed in the water pump 12, and then output from the output end and injected into the nebulizer 3. At this time, the sprayed water mist corresponds to the patient's inhalation link, so that the medicine liquid is inhaled by the patient. When the water pump 12 only draws water, only water is injected into the nebulizer 3. At this time, the atomized water mist corresponds to the patient's exhalation link, thereby avoiding the waste of medicine liquid caused by providing medicine in the exhalation link. At the same time, only water mist will form a certain flushing and moisturizing effect on the patient's skin, thereby avoiding the medicine adhering to the patient's skin and causing irritation.

[0039] Among them, a second arc groove 37 is opened on the top surface of the inner plate 25, and a stud 39 is fixedly connected to the top surface of the outer plate 24. The stud 39 passes through the second arc groove 37, and a fixing nut 40 is threadedly connected to the stud 39. When the fixing nut 40 is tightened, the outer plate 24 and the inner plate 25 are relatively fixed.

[0040] When rotating the inner plate 25 or the rotating wheel 33, the fixing nut 40 is loosened to make the rotation of the inner plate 25 or the rotating wheel 33 easier. After the rotation is completed, the fixing nut 40 is tightened to fix the outer plate 24 and the inner plate 25 relatively to avoid the inner plate 25 or the rotating wheel 33 from deflecting during operation, resulting in a change in the notch angle, thereby causing a change in the amount of liquid medicine supplied at a single time.

[0041] The top of the liquid medicine hopper 13 is fixedly sleeved with a liquid medicine cup cover 5 , and the tops of the liquid medicine cup cover 5 and the water inlet 6 are both provided with ventilation holes penetrating therethrough to balance the internal and external air pressures.

[0042] If no ventilation holes are provided at the medicine cup cover 5 and the water inlet 6, as the medicine flows from the medicine hopper 13 into the hose 15, factors such as air pressure will cause the speed of the medicine flowing downward to change, thereby failing to ensure that a fixed amount of medicine is provided to the nebulizer 3, thereby affecting the treatment effect.

[0043] A display screen 8 , a switch 9 and a plurality of knobs 10 are fixedly disposed on the front side of the housing 1 , and one knob 10 controls the rotation speed of the motor 21 .

[0044] Working principle:

[0045] When using the device to perform aerosol drug administration treatment on a patient, the patient's breathing frequency is first measured, and then the angle between the notches of the outer plate 24 and the inner plate 25 is adjusted. While rotating the inner plate 25, the rotating wheel 33 is driven by the second connecting column 35 to rotate synchronously. After the adjustment is completed, the inner plate 25 and the outer plate 24 are fixed by the fixing nut 40.

[0046] At the same time, according to the different dosages of medicine required for treatment, the slider 16 is slid up and down so that the dosage of medicine loaded in the hose 15 at a time is the same as the actual single supply requirement. At this time, driven by the linkage frame 17, the outer plate 24 and the inner plate 25 move up and down together.

[0047] After the preparation is completed, the medicine liquid is injected into the medicine liquid bucket 13, and then water is injected into the water tank 11 from the water inlet 6, and then the water pump 12 and the motor 21 are turned on. As the motor 21 rotates, the pressing valve 14 and the squeezing block 27 are triggered intermittently, so that the medicine liquid in the medicine liquid bucket 13 intermittently flows into the hose 15, and then as the water pump 12 draws, a certain amount of medicine liquid and water are mixed by the water pump 12 and input into the nebulizer 3, and then the mixed liquid is atomized by the nebulizer 3 and inhaled by the patient.
