Description of the invention (1) (please read the note on the back before filling in this page) The present invention generally relates to the field of drug delivery, especially drug delivery to the lungs ", especially The present invention relates to aerosolization of medicines for inhalation by patients. Effective drug delivery to patients is very important for the treatment of drugs. ° Currently, different delivery methods exist, each with its own advantages and disadvantages. Tablets 'capsules, oral drug delivery of drug fermentation may be the most convenient method of delivery', but many drugs will be broken down by digestive enzymes in the digestive tract before they are absorbed. Modern protein medicines are especially problematic. Subcutaneous injection is often an effective method of systemic drug delivery, including protein delivery, but patient acceptance is low β. Because drugs, such as insulin, injections, often cause pain to patients once or several times a day, many different forms of medication have been developed It comes out, including trans-canal delivery, intranasal, intra-vaginal delivery, and pulmonary delivery. Β Printed by the Cooperative Society of the Ministry of Economic Affairs, temporary intellectual property bureau. The most interesting aspect of the present invention is that pulmonary drug delivery depends on dispersing or nebulization. The drug is inhaled by the patient so that the active drug in the dispersal can reach the far (alveolar) area of the lungs. It has been found that certain drugs can be directly absorbed into the blood circulation through the alveolar region and β-pulmonary delivery is particularly effective for proteins and polypeptides which are more difficult to rotate by other inhalation methods. This type of pulmonary delivery is very effective for systemic and local delivery to treat lung disease. Pulmonary drug delivery (both systemic and local) can be performed in different ways on its own, including fluid neutralizers, fixed dose inhalers (MDI's), and dry powder dispersing devices. The dry powder body powder device is particularly effective for delivering protein and poly (peptide) medicines made into dry powder. Many other unstable proteins and polycondensation acids can be freeze-dried stably by themselves with proper powder loading.

When aerosolizing the powder is required, the aerosolizing mechanism 32 is inserted into the container 12 to contact the powder. Then, the release valve 28 is quickly opened to quickly release the metered gas in the metering chamber 26. The metering gas passes through the tube 30 and enters the powder in the gas atomizing mechanism 32 'extraction container 12, and sucks the powder in a high-pressure gas stream to form a mist. The mist can be captured in a capture chamber so that it can be inhaled by a patient. Therefore, the system 101 is constructed to operate simply by releasing a metered amount of pressurized gas, and the pressurized gas system is obtained by extracting the gaseous portion of a propellant that has previously been in equilibrium with a liquid portion. The system 10 is structured to allow a fixed pressure gauge to a fixed amount of gas. In this way, the gas atomizing mechanism 32 can evenly accommodate a known gas vessel under a known pressure, so that this paper size is applicable to the Chinese national standard (CNS > A4 specification (210x297 public love).

Description of the invention (8) It can ideally extract and aerosolize the powder in the container 12. With this configuration, several advantages can be prepared * For example, 'The system 10 is easy to operate, because only The metering valve 24 is opened and the release valve 28 is opened to aerosolize the powder. Another advantage is that the size of the system 10 can be reduced by using a propellant. "Basically" only a small amount of propellant is needed to make the size of the storage tank 14 It can be quite small. This configuration reduces the overall size of the system 10, so that the user can conveniently and easily carry and store it "Basically, the system 10 has a longer service life than the MDI device because the system 10 only One gaseous state using propellant Some are aerosolized powder, not the liquid part used in MDI devices. In addition, the system is easier to manufacture and use than MDI devices (because the patient does not need to shake the propellant) because the drug does not need to be suspended Hanging in the liquid portion of the propellant. Preferred propellants that can be used in system 10 include HFA or HFC, such as hydrofluorocarbon 134a (HFC-134a, 1,1,2-tetrafluoroethane and hydrofluorocarbon 227ea Deuterium (: -2276 &, 1,1,1,2,3,3,3-heptafluoropropane). These propellants are of conventional skill and can be purchased from Minnesota Mining & Manufacturing Co. and Dupont. Such propulsion Agents are particularly useful because they do not require the use of CFCs. Other propellants that can be used in the present invention include C02, CFC3, etc. Now referring to Section 2A, an exemplary τ device 34 for aerosolizing a powder drug will be described below The device 34 includes a base unit 36 and a capture chamber 38 removably connected to the base unit 36. The capture chamber is configured to slide on the base unit 36 to reduce the entire size of the device 34 during storage, so that Internal components provide some level of protection Room 38 also includes a mouth tube.

Printed inventor (9) 40, it can be turned on a level and Between the open position. When the gas is atomized, the nozzle tube .40 is in the closed position as shown in Figure 2. When the patient is ready to inhale the aerosolized medicine, the mouthpiece 40 is rotated 180 degrees to the open position so that the patient can place his mouth on the mouthpiece and inhale the powder medicine in the capture chamber 38. Except for the small size, the overall shape and appearance of the capture chamber 38 and the bottom element 36 are similar to those disclosed in the application 60 / 087,929. "When using a propellant to aerosolize a medicine, the bottom element 36 does not need to be round. The cylinder compresses the gas in the gas of the cylinder, and does not require a lever to place the patient's hand to prepare the energy of the compressed gas. Therefore, the size of the bottom unit 36 can be reduced. By way of example only, the height of the bottom unit 36 may be between about 8 cm and 12 cm. The height of the capture chamber 38 is between about 9 cm and 13 cm. Referring again to Fig. 2, the bottom unit 36 includes a hole 42 into which a container containing a powder medicine is inserted. The base unit 36 also includes a fire button 44 which is ground to perforate the container and releases a certain amount of pressurized gas to aerosolize the medicine in a container such as described below. A release button 46 is provided to allow the container to be removed from the hole 42 after aerosolization of the drug. The bottom unit 36 further includes a lever 48, which can be operated to calculate the amount of pressurized gas as described below. Referring now to Figures 3 and 3A, the elements within the base unit 36 will be explained. Arranged in the bottom unit 36 is an aerosolization mechanism 50, which extracts medicines from a container 52 to suck away the medicines in a high-pressure air stream, and sends the aerosolized medicines to the capture chamber 38 by turns. The base unit 36 also includes a rack assembly 54. When the fire button 44 is pressed down, it moves the container 52 to connect the gas atomizing mechanism 50, the gas atomizing mechanism 50, the stage assembly 54 and the related components. In general, the disclosures in the 60 / 087,929 patent are the same. In this way, the method of its construction < Please read the notes on the back before filling this page) h The size of the bound paper is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) 12 A7 B7 Main and Invention Description (i 〇) Only briefly described here. To operate the device 34, the container 52 is inserted into the hole 42 as described above (see Fig. 2). Then, push the fire button 44 to engage the container 52 and the aerosolization mechanism 5 '. In particular * when the fire button 44 is pushed, the gear teeth 56 rotate around a pivot pin 58, causing a pusher 60 of the stage assembly 54 to move the container 52 toward the aerosolization mechanism 50. When the fire button 44 is fully depressed, a tip 62 and a side punch 64 are perforated 'through the container 52 and enter the container. Pressing the fire button 44 also operates a valve 66 to allow a metered high-pressure gas to be released into the gas atomizing mechanism 50, so that the powder in the container 52 can be gas atomized. In particular, the pressing of the fire button 44 caused the valve actuator 68 of a starting arm 70 to be released from a center position to open the valve 66 »Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs once the valve 66 is opened 'on the bottom unit The metered high-pressure gas in 36 caused the valve 66 to "open suddenly. In particular, the release of the valve actuator 68 caused the metered high-pressure gas to contact the underside of the membrane 72, causing a valve seat 74 to lift from a slot 76. In this way, the propellant can flow through the tank 76 and enter the aerosolization mechanism 50. Then, the high-pressure gas extracts the powder medicine from the container 52, disperses the powder medicine, and drives the powder medicine device into the capture chamber 38 as described above. To operate the device 34, the user only needs to insert the container 52, and then press the fire button 44, which will cause the aerosolized medicine to enter the capture chamber 38, and can be withdrawn through the mouth tube 40. Referring again to FIGS. 3 and 3A, the following A method for supplying pressurized gas to the gas atomizing mechanism 50 through the valve 66 will be explained. The bottom unit 3 < 5 includes a storage tank unit 78, which is composed of a bottom element 80 and a top element 82. The bottom element 80 is also shown in the first In the figure, the top element 82 Shown in Figures 10A and 10B. The button element 80 includes a hole 84 and the top element 82 includes a hole 86.

The printed housing 98 of the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs can be conveniently divided into a bottom portion 11 and a top portion 112 ^ when the metering valve 96 is closed When in position, the gaseous propellant is maintained within 11% of the bottom portion. When the counter valve 96 is opened, the gaseous propellant quickly enters the top portion 112 and enters a metering tube 114. Thus, the volume in the top portion 112 and the metering tube 114 defines a metering chamber 116. On the opposite end of the metering chamber 116 is a valve 66 whose function is to prevent pressurized gas from flowing out of the metering chamber 116 until the valve actuator 68 is released as described above. When the valve 66 opens, the The gas pan rapidly enters the groove 76, where the gas enters the gas atomizing mechanism 50 »As shown in Figs. 3, 4 and 12, a valve actuator 118 is disposed on the general body 98. The valve starter 118 has a slot 120, which allows an internal 122 and a measuring tube 114. 14 This paper size applies to the Chinese National Standard (CNS) A4 (210 X 297 mm). Printed by A7.

In this way, when the lever 48 is moved, the valve actuator 118 is moved down to open the valve 96 (see FIG. 3A). Therefore, the operation of the lever 48 closes the valve 66 and then opens the metering valve 96. In this way, the metering chamber can be filled with pressurized gas. When the lever 48 is moved backward, the 'metering valve 96 is closed, so that the pressurized gas is maintained in the metering chamber. As shown in Figures 4 and 5, the base unit 36 has a lever 48 in an original position. As before, in this position, the metering valve 96 is in its normal closed position. When the fire button 44 has been depressed, the valve 66 is in its normal open position. As shown in Figures 6 and 7, the lever 48 begins to move away from its original position. As such, the extension 138 engages the bottom member 80 to move the arms 130 and 132 downward. In turn, the valve block arm 148 moves below the protrusion 150 to close the valve 66. At the same time, the valve actuator 118 moves downwards until it engages the valve valve 104 (see FIG. 7). As shown in FIG. 5, the valve actuator 118 is separated from the valve valve 104 when the lever 48 is in its original position. . Thus, when the position of Fig. 7 is reached, the starter 118 has not pushed the valve valve 104 downward. As such, the valve 66 is closed before the metering valve 96 is opened. As shown in Fig. 8, the lever 48 is fully pivoted, causing the valve actuator us to force the valve valve 104 downward. As such, the metering valve 96 is opened to allow the pressurized gas in the bottom portion 110 to flow out into the metering chamber 116. Then, the lever 48 can be moved back to its original position to close the metering valve 96 < * When the lever 48 is moved back to its original position, the valve group arm 148 is maintained below the protrusion 150 so that the pressurized gas is maintained in the metering chamber 116 .

Description of the invention (l5) < Please read the note on the back before filling this page) The advantage of using the storage tank unit 78 to support a propellant is that the entire size of the bottom unit 36 can be cut back. At the same time, the storage tank unit 78 can support a sufficient amount of propellant so that many doses can be supplied to the patient. By way of example only, the holes 88 may be configured to support HFC fluids of approximately 2cc. This allows the device 34 to be activated 100 times using a gaseous HFC of about 0.65 cc. Thus, the metering chamber 116 is preferably configured to support a gaseous HFC of about 0.65 cc. It should be understood, however, that the storage tank unit 78 and the metering chamber 16 may be configured to support other amounts of propellant. Although the storage tank unit 78 is shown in the figure, it should be understood that other embodiments of the propellant source may be provided. For example, the storage tank unit 78 may be replaced with a container or other replaceable tank, so that the container or tank can be replaced when the propellant runs out. Since the aerosolization mechanism 50 is preferably replaced periodically, the propellant source can be configured to connect to the aerosolization mechanism so that both can be removed and replaced when the propulsion system is used up. Printed by Temporary Property of the Ministry of Economic Affairs and Employee Consumer Cooperatives. When HFA is used as the propellant, the pressure of the gaseous portion in the metering chamber 116 is preferably between about 40 psi and about 120 psi, more preferably between about 50 psi and about SOpsi. It is advantageous to configure the device 34 to operate with a wide range of pressures, as the pressure of the HFC can be changed depending on the atmospheric temperature. In this way, the device 34 can be used in many different environments and climates.
