Description

Drug delivery device

The present invention relates to a delivery device, and more particularly to a drug delivery device for spraying aerosolized medicinal liquid on a human body treatment site and supplying a bead size required for treatment.

Respiratory diseases of the human body have a significant impact on the quality of daily life of patients. Taking the symptoms of nasal cavity as an example, the use of nebulizer products for medical treatment by spray method is a popular medical method in recent years. Its advantages can avoid long-term systemic administration of oral medicines, which leads to drug residues that are not easy to be excluded from the body and side effects. And other issues.

Check, the atomization method of the conventional nebulizer can be roughly divided into the pneumatic principle or the ultrasonic principle technology as the action mechanism; however, due to the various areas of the nasal cavity (such as the sinus area including the upper nose, middle nose, lower nose Tract, olfactory cleft, oral and nasal tract complex, and sinus cavity) have different diameters of the medicament mist. Patients often have to receive various types of equipment for treatment, and there is a lack of a large amount of medical resources.

Please refer to the third figure, which is a schematic diagram of the controller of the drug delivery device of the present invention. As shown in the figure, the controller 14 is a rotatable adjustment button. As an operation interface, it has the options of OFF, the number of oscillating segments 2, 3, 4, 5, 6, and other options for users to choose. Turn clockwise or counterclockwise to enable or disable related options. Among them, except that OFF is the option to turn off the operation of the atomizing module 12, and the spraying module 16, the rest of the vibration segments 2 to 6 are also started together to start the atomizing module 12. 、 The state of the spray module 16 (ON). The number of oscillating segments 2 to 6 is used to turn on the electrical connection relationship between the power supply 18 and the ultrasonic oscillating sheets 120. For example, the number of oscillating segments 2 represents the selection of the highest oscillating frequency segment, and the number of oscillating segments 3 The number of segments representing the next highest oscillation frequency is selected by analogy. The number of oscillating segments is not limited to 2 to 6. When the appearance preset of the drug delivery device 1 of the present invention can be used, the number of oscillating segments and the number and specifications of the ultrasonic oscillating film 120 are determined. The purpose of the controller 14 is to match the power supply 18 to enable / disable the atomization module 12, the spray module 16, and change the operation mode of the atomization module 12. However, the above-mentioned controller 14 is a rotatable adjusting button, which is only one of the aspects, and may also be constituted by a plurality of button arrangements, and is not limited to the examples in the embodiment of the present invention.

Please refer to the fourth figure, which is a schematic diagram of an ultrasonic vibration tablet of the drug delivery device of the present invention. As shown in the figure, in the fourth figure, five ultrasonic oscillating sheets 120 having the same thickness D are stacked to form the atomizing module 12, and the second accommodating space 1024 (as shown in the first figure) is used for illustration. Electrodes (or conductive materials) are respectively provided at both ends of each ultrasonic oscillating sheet 120. Since the ultrasonic oscillating sheets 120 are stacked to form the atomizing module 12, two adjacent ultrasonic oscillating sheets 120 can share one electrode The ultrasonic oscillating pieces 120 are connected to the controller 14 and the power supply 18 by the electrodes E1 to E6, and it is determined that at least one of the ultrasonic oscillating pieces 120 is turned on and starts to operate. For example, the power supply 18 maintains a connection relationship with the electrode E1. When the controller 14 selects the number of oscillating segments 2, it means that the electrode E2 is connected to the power supply 18, and the ultrasonic vibration sheet 120 of the first layer L1 is turned on. At this time, the electrodes E1 and E2 apply a voltage to the surface of the ultrasonic oscillating sheet 120 of the first layer L1. According to the design principle of the ultrasonic oscillating sheet 120 itself, it starts to resist the change to extend along the direction of the electric field to generate mechanical energy, causing the drug delivery device 1 to vibrate. . Similarly, when the controller 14 selects the number of oscillating segments 3, it means that the electrodes E1 and E3 are connected to the power supply 18, and the ultrasonic oscillating sheet 120 of the first layer L1 and the ultrasonic oscillating sheet 120 of the second layer L2 are turned on. Began to operate; however, since each ultrasonic oscillating sheet 120 is of the same thickness D, when the ultrasonic oscillating sheet 120 of the second layer L2 is actuated, the thickness of the ultrasonic oscillating sheet 120 of the first layer L1 is added. D, will make the oscillation frequency of oscillation number 3 less than the oscillation number 2. That is, as the distance from the first accommodating space 1022 increases, the vibration frequency generated when the ultrasonic oscillating sheet 120 on the lower level is turned on is smaller. Of course, the thickness of each layer of the ultrasonic oscillating sheet 120 of the present invention does not necessarily have to be the same, and can also be arranged in combination, and the atomizing module 12 is formed in the same, completely different, or partially the same manner.

The operation of the drug delivery device 1 of the present invention will be described below. First, a liquid W has been set in the first accommodating space 1022 (as shown in the first figure), and the liquid W is a medicinal solution for the user's mouth and nose to inhale. When the user wants to implement the present invention, one of the number of oscillating segments 2 to 6 of the operation controller 14 may be selected. This embodiment is described on the premise that the user selects the number of oscillating segments 2. When the user rotates the controller 14 and selects the number of start-up oscillation stages 2, the controller 14 and the atomization module 12, the spray module 16, and the power supply 18 have an electrical connection relationship, so the power supply 18 starts to supply together. The electric power is supplied to one of the ultrasonic wave oscillating sheet 120 of the atomizing module 12 and the exhaust fan 162 of the spraying module 16. That is, the number of oscillation stages of the controller 14 is selected, so that one of the ultrasonic vibration plates 120 and the electrical connection relationship between the exhaust fan 162 and the power supply 18 is rendered conductive.

For the previous paragraph, please refer to the fifth figure, which is a schematic diagram of the operation of the drug delivery device of the present invention. As shown in the figure, the ultrasonic oscillating sheet 120 acts to vibrate the casing 100 based on the principle of ultrasonic oscillation, so that the liquid W of the first accommodating space 1022 starts to oscillate and atomize into a plurality of liquid beads W ', and the fan 162 will be suspended in The liquid beads W ′ in the first accommodating space 1022 are transported toward the nozzle 160, and finally leave the drug delivery device 1 and be discharged to the external environment. When starting the present invention, the user can first point the nozzle 160 at the mouth / nose part. When the liquid W is atomized into liquid beads W 'and discharged to the external environment, it will directly enter the mouth / nasal cavity for the user to absorb the medicinal solution (liquid Beads W ').

The operating frequencies of the ultrasonic oscillating plates 120 of the present invention are in the range of 0.1MHZ to 10MHZ, and include frequencies of 0.1MHZ and 10MHZ, or as long as they belong to the specification of the ultrasonic vibration frequency range (KHZ ~ MHZ interval). It is not limited to this. Therefore, according to the number and specifications of the ultrasonic oscillating sheet 120 of the atomizing module 12, the number of oscillating sections can be set correspondingly. The liquid W is actuated by the ultrasonic oscillating sheets 120 to generate liquid beads W 'having a particle diameter ranging from 1 m to 10 m. For example, the ultrasonic vibration sheet 120 with a vibration frequency of 0.3MHZ and the vibration liquid W generate liquid beads W 'with a particle size of about 10 μm, and the ultrasonic vibration sheet 120 with a vibration frequency of 0.5MHZ correspond to the liquid beads with a particle size W ′ of 7 μm and a vibration frequency. The ultrasonic vibration sheet 120 of 1MHZ specification forms liquid beads W ′ with a particle diameter of 4.3 μm. Therefore, the drug delivery device 1 of the present invention can adjust the controller 14 according to the needs of the user, thereby obtaining a way for the user to easily absorb the medicinal solution (liquid beads W '). Until the user no longer needs to suck the liquid beads W 'for treatment, or the liquid W set in the first accommodating space 1022 has been used up and needs to be filled, the controller 14 can select the OFF option to stop the drug delivery device 1 to stop operation.

In summary, the effects that the drug delivery device can achieve are: 1. The present invention has multiple vibration frequency options to supply the user's treatment needs, and the particle size absorbed by the liquid beads can be adjusted in time to improve the user's treatment efficiency. Furthermore, the traditional application of the mouth / nose atomizing device can only obtain a single bead particle size in a single frequency manner, and the provided bead particle size is too large to be conducive to user absorption. 2. The liquid beads can be continuously treated for the user after the invention is started, unless the drug delivery device is turned off by the user, or the liquid is not enough for the user to treat, and only the atomizing module and the exhaust fan are left idle. Need to close. In this way, the conventional mouth / nose atomization device has a certain time limit when it is started, such as the lack of self-closing after 1 minute of startup.

In summary, it is only a description of the preferred implementations or examples of the technical means adopted by the present invention to solve the problem, and is not intended to limit the scope of patent implementation of the present invention. That is, all changes and modifications that are consistent with the meaning of the scope of patent application of the present invention, or made according to the scope of patent of the present invention, are covered by the scope of patent of the present invention.
