Definitions
- the present invention relates to an apparatus and a method for dispensing a powdered body, and more particularly to a multi-dose device for a powdered drug.
- the present invention relates to a multi-dose powder medicine that can be divided and weighed into a small amount of powder medicine for a single administration operation with a high degree of quantitative quantification, and the powder medicine for multiple administration operations stored in the main unit can be sprayed.
- the dosing device related to the dosing device.
- the present invention provides a method for continuously and accurately dividing a single administration operation into a powdered drug and spraying it into a body cavity such as a nasal cavity, an oral cavity, a trachea, a bronchus, an alveoli, or other affected areas. It is intended to provide a relatively inexpensive powder drug multi-dose device for inhaled administration, which is sanitary, convenient to carry, easy to use, and relatively inexpensive. Background art
- Powdered drugs are administered to the body cavities, such as the nasal cavity, oral cavity, and respiratory tract by inhalation or inhalation.
- a powdery drug is sprayed into the nasal cavity for nasal allergy patients, and administered to the respiratory tract by inhalation for asthma patients.
- it is administered by spraying into the oral cavity.
- a drug delivery system that allows a drug to be absorbed into the systemic bloodstream through mucous membranes such as the nasal cavity and lungs has attracted attention, and attempts have been made to administer powdered drugs to those mucous membranes.
- peptide-protein drugs such as insulin and calcitonin, or drugs that require immediate action such as migraine drugs, etc.
- inhalants and the like have been carried out, and many reports have shown that the absorbability is better than that of oral preparations.
- a powdered drug dispenser In the administration of such powdered drugs, a powdered drug dispenser is used, and such dispensers are roughly classified into the following two types depending on the method of storing the powdered drug.
- the amount of powdered drug for a single administration operation is stored as a unit in the dispenser itself, or in a suitable container such as a capsule. It is a so-called single dose device that can only administer drugs. Some of these are disposable types that can be discarded after a single administration operation.
- the second is that a plurality of (multiple) administrations of the powdered drug are collected and stored in an appropriate container, and a single operation of the powdered drug can be divided and administered from the container. This is called a dispenser.
- the amount of the single dose operation of the powdered medicine is referred to as “single dose”, and the amount of the multiple dose operation is referred to as “multiple dose”.
- a single-dose dispenser for a powdered drug is disclosed in Japanese Patent Application Laid-Open No. 59-34267 and the like, which enables spraying into the nasal cavity.
- a single dose of the powdered drug is generally stored in a container such as a capsule, and a holder for the container, a means for piercing the container, and a device for transferring the powdered drug from the container to the patient.
- a means for introducing an air flow for spraying into the nasal cavity and the like is provided.
- Japanese Patent Publication No. 2-500172 discloses a fine powder drug, and the head has an opening for spraying or inhaling the drug.
- a dispenser comprising: a holding portion configured to be formed; and air introduction means, and a bottom portion of the holding portion connected to the air introduction means via a drug-impermeable gas-permeable diaphragm.
- WO / 04826 an improved dosing device is disclosed.
- Many single dose dispensers for powdered drugs to be inhaled into the respiratory tract have been published.
- a dispenser for inhalation using capsules usually used in pharmacy.
- the capsule contains a single dose of the powdered drug to be inhaled and is provided with a respective means for piercing the capsule with a respective dispenser.
- the powdered medicament is administered by the air flow created by the suction action by the user.
- each of the dispensers is characterized by the air flow at the time of inhalation and the state of the capsule, and is disclosed in US Pat. Nos. 3,906,950 and 4,013,075.
- No. 3,807,400 discloses a capsule in which both ends of a capsule are pierced and the capsule becomes stationary during inhalation, and a capsule in which the capsule is moved during inhalation.
- the specification of W094 / 26338 is disclosed as a device capable of administering a spray.
- the specification includes an apparatus main body, a storage chamber detachably attached to the apparatus main body and capable of storing multiple doses of a drug, and a storage chamber having a capacity for a single dose.
- the medicine dispensing means movably attached to the main body of the device for communicating the storage room with the storage room at the filling position and enabling the administration of the medicine in the storage room, and the storage room through the storage room at the filling position.
- the disclosed device is disclosed.
- a nasal content administration device is described in European Patent Publication No. 0744188, which discloses a manual source of air flow for spraying powdered medicine, and multiple dose administration.
- a nasal applicator comprising a reservoir for a quantity of powdered drug, a drain for the powdered drug, and a facility for dispensing multiple doses of powdered drug into a single dose.
- the equipment for the powdered drug consists of a drum-shaped powdered drug storage room and a plurality of single It consists of a rotating sleeve with a storage chamber for storing the dose of the drug.
- the dispenser As a dispenser for a powder drug to be administered by inhalation into the respiratory tract, there is one as described in JP-A-0211595.
- the dispenser is designed to be filled with a disc-shaped pack inside the device, which has a series of air bubbles near each other and equidistant from each other and from the center of the pack. I have. These bubbles contain a fixed amount (single dose) of powdered drug.
- the pack is mounted on a rotatable circular tray about its center line. This tray has a hole at the position corresponding to the air bubble, and when the air bubble moves to a predetermined position where it can be broken by an appropriate opening device, the powdered drug can be taken out and inhaled. It is structured
- a scraper device is also provided to level the side of the through-hole formed in the plate facing the powder drug container.
- the scraper device provides a complete filling of the through-holes and thus ensures a constant dose.
- the description states that this scraper device is not necessary.
- the inhaler is essential for proper operation. This is because without this scraper the dose would be extremely different. This is because the powdered drug used often has poor flowability, and it often happens that the through-holes are not completely filled with the powdered drug.
- a multiple dose device tends to be more desirable in terms of convenience and marketability. That is, in the case of a single dose device, for example, a device such as Japanese Patent Application Laid-Open No. 59-34267 requires a container such as a capsule in which a single dose of a drug is enclosed in advance, and the inside of the device. Are equipped with means for piercing the container. Therefore, according to the usage of each dispenser, the user needs to mount a container containing the powdered medicine and perforate it. This is not convenient for users. Also, the user must carry the dosing device and a container with the powdered medicament in preparation for dosing, which is also problematic in terms of convenience. Also, the specification of W097 / 04826 shows a simplified administration operation. In this case, a user who needs multiple administrations is required to prepare a plurality of single-dose drugs. It requires an enclosed dispenser and remains a portability issue.
- 0744188 also discloses a drum type powder drug storage chamber and a storage chamber for storing a plurality of single dose drugs inside the drum type powder drug storage chamber as means for quantitatively dividing the drug. Although it is proposed to be composed of a rotating sleeve with a slab, it is relatively complex and formed from a large number of parts, and the difficulty in molding and the accompanying high cost are problems.
- Japanese Patent Application Laid-Open No. 3-18376 discloses a multiple dose device which compresses a large amount of powdered drug and continually divides the resulting powdered drug into fixed quantities and scrapes it off. .
- the powdered drug is compressed to ensure the quantitativeness of the drug to be divided.However, in this method as well, vibration is applied to the entire dispenser, so that the powdered drug compact is compressed.
- This has the disadvantage that the bulk density of the powder changes, and as a result, the weight of the powdered drug compact to be scraped off changes, and as a result, the amount of drug administered to the living body becomes inconsistent.
- the means for uniformly dividing these powdered drugs is relatively complicated, and in actual use for clinical use, there are also problems such as difficulty in molding and the accompanying high cost.
- the multi-dose dispenser as described in W094 / 26338, etc. is constructed such that by passing an air flow through the collected powder medicine in the storage chamber immediately before each dividing operation, the collected medicine is moved in the storage chamber space. Prevents changes in the density of the powdered drug and dispenses a single dose of powdered drug into suction and / or gravity A single dose of drug can be divided and administered continuously and quantitatively by storing it in a powdered drug storage room.However, a storage unit, a drug storage room for a single dose, and a drug quantitative dividing means , A large size that is composed of pump means, etc., and that requires ample space to move the powdered medicine so that the density does not change. The challenge is to become a dosing device.
- the drug to be administered is dispersed in the primary powder particles constituting the drug and deposited at the administration site when the drug is separated from the administration device.
- some particles undergo agglomeration during storage to form secondary particles, and the primary particles tend to have a larger particle size distribution. Therefore, when the powdered drug leaves the dispenser, it is desirable that even if it agglomerates during storage in the dispenser, it can be dispersed to primary particles by contriving the structure of the dispenser.
- the conventional powder drug dispenser has the following advantages: quantitativeness of the dose of drug to be administered, portability due to miniaturization, simplicity of operation, quick operation, simplicity of the manufacturing process, simplicity of components, and low cost for manufacturing. At present, none of them satisfy all the conditions, such as stability and dispersion of powdered drug particles. Disclosure of the invention
