Description

Technical Field

[0001] The present invention belongs to the technical field of respiratory drug delivery devices, and in particular relates to a drug delivery device for respiratory medicine. Background Art

[0002] In the treatment of respiratory diseases, inhalation drug delivery devices (such as dry powder inhalers (DPIs), metered-dose inhalers (pMDIs), and soft mist inhalers) have become a mainstream treatment option because they can deliver drugs directly to airway targets and reduce systemic side effects. However, the design of existing devices is highly dependent on the patient's spontaneous inhalation ability. When used in patients with respiratory muscle weakness, advanced chronic obstructive pulmonary disease (COPD), neuromuscular diseases (such as amyotrophic lateral sclerosis), or postoperative weakness, their drug delivery efficiency is significantly reduced, or even ineffective. This limitation has become a prominent pain point in clinical practice. Summary of the Invention

[0003] In view of the above situation, in order to solve the current problems of respiratory muscle weakness of patients, difficulty in obtaining medicine, excessive dosage due to mismanagement of medicine, and backflow of medicine due to patient breathing when the disease occurs, the present invention provides a respiratory medicine drug delivery device, which gradually solves the above problems and solves the problem that the patient's mouth is difficult to open in the state of muscle weakness, thereby achieving the design effect of autonomous drug delivery after the device is placed in the mouth.

[0004] The technical solution adopted by the present invention is as follows: A respiratory medicine drug delivery device provided by the present invention includes a casing, in which a single-press drug delivery device, an anti-backflow spraying structure, and an assembly loading device are provided. The single-press drug delivery device is installed at the end of the casing, the anti-backflow spraying structure is installed at the front end of the casing, and the assembly loading device is installed in the middle position of the casing, and the two ends of the assembly loading device are respectively connected to the single-press drug delivery device and the anti-backflow spraying structure.

[0005] Furthermore, the housing includes a hand-holding portion and a lip-pressing portion, the hand-holding portion is designed as a three-dimensional structure with a constant thickness, and the lip-pressing portion is designed as a three-dimensional trapezoidal structure with a gradually changing thickness.

[0006] Furthermore, a first card slot is provided on the side wall of the lip pressing portion, and a lip tooth pressing slider that is engaged and slidable is provided in the first card slot.

[0007] Furthermore, the single-press medicine-feeding device includes a pressing plate, a driving rack, a driving gear, a limiting ratchet, a limiting ratchet ring, a limiting protrusion, a worm gear, and a worm. The driving rack is engaged and slid on the casing, and the pressing plate is fixedly installed on the driving rack. The driving rack and the casing are connected by a spring. The driving gear is engaged and rotatable in the casing, and the driving gear and the casing are connected by a torsion spring. The driving rack is meshed with the driving gear, and the limiting ratchet is fixedly connected to the driving gear through a bracket. The limiting ratchet ring is engaged and rotatable on the inner wall of the casing, and the limiting protrusion is engaged and rotatable in the limiting ratchet ring. The limiting protrusion is engaged and rotatable with the limiting ratchet ring. The rings are connected by a torsion spring, the limiting protrusion is in contact with the limiting ratchet, the worm wheel is engaged and rotated in the casing, the worm is fixedly connected to the limiting ratchet ring, and there is no fixed bracket for connection between the limiting ratchet and the limiting ratchet ring. The limiting ratchet applies rotational power to the limiting ratchet ring through the limiting protrusion, the worm wheel is engaged with the worm, and the limiting ratchet rotates, pushing the limiting protrusion to rotate in the limiting ratchet ring. When the torsion spring on the driving gear and the spring on the driving rack apply reaction force, the driving gear presses the limiting protrusion to rotate in the opposite direction, and the limiting protrusion contacts and presses the protrusion in the limiting ratchet ring, causing the limiting protrusion to drive the limiting ratchet ring to rotate, thereby realizing the rotation of the worm.

[0008] Furthermore, the single-press medication device also includes a gear assembly, a medicine tray and a strip-shaped medicine combination. The gear assembly is engaged and rotatably arranged in the housing, and the gear assembly is connected to the worm gear. The medicine tray is fixedly arranged on the gear assembly, and the strip-shaped medicine combination is engaged and installed in the medicine tray.

[0009] Furthermore, the assembly loading device includes a snap-fit ​​cover, a circular pressing plate, a circular pressing groove, a pressing cone, a guide tube, and a baffle. The snap-fit ​​cover is snap-fitted and installed on the casing, and the snap-fit ​​cover is fixed relative to the casing after being assembled on the casing. The circular pressing groove is provided on the snap-fit ​​cover, and the circular pressing plate snaps and slides on the circular pressing groove. The pressing cone is fixedly installed on the bottom wall of the circular pressing plate. A medicine discharge port is provided on the bottom wall of the medicine tray, and the guide tube is fixedly connected to the medicine discharge port. The baffle is snap-fitted and rotatably arranged in the guide tube. After the pressing cone punctures the medicine package, it is further moved downward to press and tilt the baffle, and the medicine flows downward along the guide tube. A torsion spring is provided at the connection between the guide tube and the baffle.

[0010] Furthermore, in order to make it easier to puncture the medicine package, a cross cutting line is provided on the medicine package of the strip medicine combination, and it is more labor-saving to press the cone to puncture the medicine package; in order to facilitate the observation of how many groups of medicine packages in the strip medicine combination have not been punctured, the snap cover is set to a transparent material, and the circular pressing plate and the circular pressing groove are connected by a spring.

[0011] Furthermore, the anti-backflow spraying structure includes an air duct, a fan, a medicine receiving trough, and a Tesla valve medicine spraying trough. The air duct is fixedly installed in the casing, the fan is snap-fitted into the air duct, the medicine receiving trough is fixedly connected to the air duct, and the Tesla valve medicine spraying trough is fixedly set in the medicine receiving trough. After the medicine enters the medicine receiving trough, the fan is energized, and the medicine is driven by wind to pass through the Tesla valve medicine spraying trough and enter the oral cavity. In order to improve the smoothness of the medicine entering the Tesla valve medicine spraying trough, the connection between the Tesla valve medicine spraying trough and the medicine receiving trough is provided with a chamfer with an inclination angle of 80°.

[0012] Furthermore, in order to realize the ability of the equipment to automatically spray medicine, and to achieve the effect that the medicine can be automatically sprayed after the lips or teeth press the lip and teeth pressing slider, a block-shaped protrusion is provided on the lip and teeth pressing slider, and a pressure sensor is provided on the card slot one. A controller is provided in the housing, and an electrical connection is adopted between the controller and the pressure sensor, and an electrical connection is adopted between the controller and the fan. When the protrusion on the lip and teeth pressing slider contacts the pressure sensor on the card slot one, the pressure sensor transmits an electrical signal to the controller, and the controller controls the fan to power on. When the pressure sensor is disconnected from the protrusion, the controller disconnects the power supply. In order that the lip and teeth pressing slider can automatically reset, a spring is provided between the card slot one and the lip and teeth pressing slider.

[0013] Furthermore, in order to avoid applying too much medicine to the patient, it is necessary to control the amount of medicine. An electromagnet is provided on the bottom wall of the pressing plate, and an electromagnet is also provided on the casing. The two sets of electromagnets are electrically connected, and the electromagnets are electrically connected to the controller. After the fan is powered on once, the controller disconnects the power supply of the electromagnet for 1 second.

[0014] This solution provides a respiratory medicine drug delivery device, which has the following beneficial effects: (1) Using the lip pressure area with a gradual thickness, the patient's lips are opened. The lip and teeth pressing slider on the lip pressure area is squeezed and slid by the lips and teeth. The pressure sensor obtains kinetic energy, thereby driving the controller to release an electrical signal to achieve automatic pressurization, blowing the medicine into the deep part of the mouth. The powder is guided through the Tesla valve spray tank, which can effectively avoid the backflow of powder. (2) The pressing plate controls the rotation of the medicine tray to a fixed angle when pressed once. Under the attraction effect of the electromagnet on the pressing plate, the medicine tray cannot be moved before the last medicine is used, effectively avoiding the problem of excessive medicine.

[0029] An electromagnet is provided on the bottom wall of the pressing plate 9 , and an electromagnet is also provided on the housing 1 . The two sets of electromagnets are electrically connected, and the electromagnets are electrically connected to the controller 32 .

[0030] Before use, first assemble the medicine, open the snap cover 20, install the ring-shaped strip medicine assembly 19 on the medicine tray 18, make the medicine tray 18 and the strip medicine assembly 19 relatively fixed, snap the snap cover 20 onto the housing 1, and when the medicine tray 18 rotates in the housing 1, the snap cover 20 and the housing 1 are always in a relatively fixed state; Before use, the medicine pack is punctured and the medicine is delivered into the device. When the previous set of medicine packs has been punctured, the next set of medicine packs needs to be moved to the medicine delivery port 26; Pressing the pressing plate 9 drives the rack 10 downward, the driving gear 11 rotates, the limiting ratchet 12 rotates, and the limiting protrusion 14 is pressed by the limiting ratchet 12 to generate displacement. The rotation angle of the limiting protrusion 14 is limited by the protrusion in the limiting ratchet ring 13. The limiting protrusion 14 is pressed by the limiting ratchet 12, and the limiting protrusion 14 drives the limiting ratchet ring 13 to rotate. The worm 16 drives the worm wheel 15 to rotate. After the transmission of the gear assembly 17, the medicine tray 18 rotates the set angle, and the new medicine package moves to the bottom of the pressing cone 23. After the pressing plate 9 is pressed, it is fixed to the housing 1 by the action of the electromagnet, and the position of the medicine tray 18 does not change. Press the circular pressing plate 21, and the pressing cone 23 pokes the medicine bag below downwards.
