Description

Technical Field

[0001] The present invention particularly relates to an atomization drug delivery device. Background Art

[0002] At present, inhalation aerosols are basically required for treating respiratory diseases such as bronchitis, asthma, pneumonia, etc. Most of the existing inhalation aerosol atomization drug delivery devices use a combination of an atomizer, an atomizer cup, and an atomizer mask. When in use, the atomizer mask is connected to the atomizer cup, and then the atomizer cup is connected to the atomizer body through the trachea. When in use, the mask is first placed on the mouth and nose, and then the atomizer is started, and the medicine in the atomizer cup is atomized and enters the human body through the mouth and nose.

[0003] In the process of using the existing mask, in order to keep the breathing unobstructed, the left and right sides of the mask are provided with vents that connect the inner cavity of the mask with the outside world. However, since the work of the nebulizer is carried out continuously during the atomization process, during the atomization process of the patient, the aerosol can be inhaled into the human body when inhaling, but when exhaling, the exhaled gas of the human body and the new gas entering the mask will enter the atomization cup at the same time, which will cause the air pressure of the atomization cup to increase sharply in a short time, thereby causing part of the aerosol to be squeezed out of the atomization cup through the vents along with the exhaled gas of the human body, which will cause this part of the aerosol to be unable to be effectively utilized, resulting in a waste of aerosol. According to specific statistics, since the normal time ratio of human breathing is inhalation: exhalation = 1:1.5, the exhalation time is greater than the inhalation time. It can be seen that in the completion of a complete atomization process, about half of the aerosol may be wasted, and the efficacy will also be reduced. Summary of the invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an atomization drug delivery device, which can greatly improve the utilization rate of aerosol and improve the atomization efficacy.

[0014] Furthermore, a guide groove is provided on the push plate, and the push end can be slidably disposed in the guide groove.

[0015] Furthermore, the driving mechanism also includes a pulley group, and the pulley group is arranged outside the medicine feeding tube. The pull rope passes through the guide of the pulley group and is parallel to the medicine feeding tube.

[0016] Furthermore, the driving mechanism also includes a stop-rotation structure, which includes a friction plate and an adjusting rod. The friction plate is arranged on the outer wall of the medicine feed tube through the adjusting rod, and the friction plate abuts against the outer wall of the rotating rod.

When the patient exhales, a large amount of gas comes from the air outlet. The gas drives the baffle to block the drug inlet through the driving mechanism to close the drug inlet, preventing the atomized aerosol from continuing to flow into the mask and being discharged from the air outlet. When the exhalation is completed and the inhalation is started, the air pressure in the mask decreases rapidly, and basically no gas is discharged from the outlet.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0031] See also Figures 1 to 5 The present invention provides an atomization drug delivery device, including a mask 100, a drug inlet tube 200, a blocking member 300 and a driving mechanism 400.

[0032] Specifically, the mask 100 is provided with a drug inlet 110 and an air outlet 120. The drug inlet pipe 200 is a hard pipe, which is connected to the drug inlet 110 of the mask 100, and can be connected to the air pipe of the atomizer cup. The blocking member 300 includes a baffle, which can be blocked on the drug inlet 110 to close the drug inlet 110. The driving mechanism 400 is arranged outside the drug inlet pipe 200 and connected to the baffle. When gas is discharged from the air outlet 120, the driving mechanism 400 can drive the baffle to block the drug inlet 110 through the gas discharged from the air outlet 120 and drive the baffle to disengage from the drug inlet 110 when no gas is discharged.

[0033] When in use, first connect the medicine inlet pipe 200 to the trachea of ​​the nebulizer cup, then place the mask 100 over the mouth and nose, then start the nebulizer body, when the patient inhales, the baffle is not blocked on the medicine inlet 110, and the atomized aerosol is taken in from the medicine inlet 110, when the patient exhales, a large amount of gas comes from the air outlet 120, and the gas drives the baffle to block the medicine inlet 110 through the driving mechanism 400 to close the medicine inlet 110, preventing the atomized aerosol from continuing to flow into the mask 100 and being discharged from the air outlet 120, when the exhalation is completed and the inhalation is started, the air pressure in the mask 100 decreases rapidly, and basically no gas is discharged from the air outlet, the driving mechanism 400 drives the baffle to disengage from the medicine inlet 110, and the atomized aerosol can enter the mask 100 from the medicine inlet 110, completing the atomization inhalation action.

[0034] By adopting the above device, by closing the drug inlet 110 during exhalation, the waste of aerosol caused by the aerosolization process can be greatly reduced, thereby improving the utilization rate of the aerosol, achieving the purpose of saving costs and improving the treatment effect. At the same time, due to the increased utilization rate of the drug, the treatment time and course of treatment can be further shortened.

[0035] In this embodiment, the driving mechanism 400 includes a rotating rod 410 , a propeller blade 420 , a fixing frame 430 , a movable frame 440 , a first elastic member 450 , a supporting rod 460 and an intermediate transmission member 470 .

[0036] The rotating rod 410 is rotatably disposed on the outer wall of the medicine inlet tube 200, and there are a plurality of propeller blades 420, which are circumferentially spaced and disposed on the rotating rod 410. The propeller blades 420 can sequentially pass through the gas outlet 120, and when gas can flow out of the gas outlet 120, the outflowing gas can push the propeller blades 420 aligned therewith, thereby driving the rotating rod 410 to rotate;

[0037] The fixed frame 430 and the movable frame 440 are both in a hollow state. The fixed frame 430 is fixed in the medicine inlet pipe 200, and the movable frame 440 is arranged in the medicine inlet pipe 200 so as to be able to slide up and down, and is located near the side of the mask 100 relative to the fixed frame 430. The first elastic member 450 is supported between the fixed frame 430 and the movable frame 440, and the baffle is located in the mask 100. The support rod 460 is arranged on the movable frame 440, and is supported on the baffle through the medicine inlet port 110. The side wall of the medicine inlet pipe 200 is provided with a through hole that connects the medicine inlet pipe 200 with the outside world, and an elastic film 480 covering the through hole is arranged on the through hole, and a push plate connected to the movable frame 440 is embedded in the middle of the elastic film 480, and the intermediate transmission member 470 is connected between the rotating rod 410 and the push plate. When the rotating rod 410 rotates clockwise, the push plate can be driven to descend through the intermediate transmission member 470.

[0038] Specifically, the intermediate transmission member 470 includes a mounting rod 471, a lever 472 and a pull rope 473. The mounting rod 471 is vertically arranged on the outer wall of the medicine inlet tube 200, and a hinge is arranged on the mounting rod 471, and is located on the side close to the mask 100 relative to the push plate. The lever 472 is hinged on the hinge, one end of the lever 472 is a pushing end, and the other end is a pulling end, and the distance between the hinge and the pushing end is smaller than the distance between the hinge and the pulling end. The pushing end can slide against the push plate, and the end of the pull rope 473 is fixed on the rotating rod 410 and connected to the pulling end. When the rotating rod 410 rotates clockwise, the pull rope 473 can be wrapped around the rotating rod 410.

[0039] When inhaling, the baffle is separated from the medicine inlet 110, and no gas flows out of the gas outlet 120. When exhaling, gas flows out quickly from the gas outlet 120 and impacts the propeller blade 420. When the rotating rod 410 is driven to rotate clockwise, the rotating rod 410 is driven to rotate, so that the pull rope 473 is wound around the rotating rod 410, thereby driving the pulling end to rise and the pushing end to fall, and then driving the baffle to fall until the baffle closes the medicine inlet 110. When exhalation is completed and inhalation is performed, no gas flows out of the gas outlet 120. Under the action of the first elastic member 450, the movable frame 440, the push plate and the baffle are pushed up, so that the baffle is separated from the medicine inlet 110 and the pushing end is pushed in the opposite direction, driving the pulling end to fall, and the pull rope 473 drives the rotating rod 410 to rotate in the opposite direction to release the line. It is used for the next breathing process.

[0040] In a specific implementation, a guide groove can be provided on the push plate, and the push end can slide in the guide groove to guide the lever 472, thereby preventing the lever 472 from moving randomly. In addition, a pulley block 700 can be provided outside the medicine inlet pipe 200, and the pull rope 473 passes through the pulley block 700 and is parallel to the medicine inlet pipe 200, thereby preventing the pull rope 473 from winding randomly.

[0041] As a preferred embodiment, the driving mechanism 400 further includes a rotation-stopping structure 490. The rotation-stopping structure 490 includes a friction plate 491 and an adjustment rod 492. The friction plate 491 is arranged on the outer wall of the medicine feeding tube 200 through the adjustment rod 492, and the friction plate 491 abuts against the outer wall of the rotating rod 410. The adjustment rod 492 can adjust the pressing force of the friction plate 491 and the rotating rod 410 on the rotating rod 410.

[0042] During assembly, the friction plate 491 is adjusted to press against the outer wall of the rotating rod 410 through the adjusting rod 492, thereby adjusting the friction force between the friction plate 491 and the rotating rod 410 to prevent the rotating rod 410 from continuing to rotate due to inertia when the rotating rod 410 is pulled counterclockwise by the pull rope 473, and affecting the subsequent pulling action of the lever 472.

[0043] As another preferred embodiment, the device further comprises an outer tube 600. The outer tube 600 is coaxially arranged with the drug inlet tube 200 and is sealedly connected with the outer cover, and the drug inlet tube 200 is connected with the outside, and the outer tube 600 covers the drug inlet 110, the gas outlet 120 and the driving mechanism 400.

[0044] During operation, the outer tube 600 can be held by hand for operation. As a further preferred embodiment, the device further comprises a drainage tube 500, which is connected to the air outlet 120 and is aligned with the propeller blade 420. Through the drainage effect of the drainage tube 500, the airflow blowing toward the propeller blade 420 can be concentrated, thereby driving the propeller blade 420 to rotate rapidly.

[0045] The use of the above-mentioned atomizing drug delivery device:

[0046] When in use, the outer tube 600 is held by hand, the medicine inlet tube 200 is connected to the airway of the nebulizer cup, and then the mask 100 is placed on the mouth and nose, and then the nebulizer body is started.

[0047] By adopting the above device, by closing the drug inlet 110 during exhalation, the waste of aerosol mist caused by the aerosolization process can be greatly reduced, thereby improving the utilization rate of the aerosol, achieving the purpose of saving costs and improving the treatment effect. At the same time, due to the improved utilization rate of the drug, the treatment time and course of treatment can be further shortened, further facilitating patients.
