20100108062 | MEDICATION INHALER - A medication inhaler comprising an inhaler body, having a medication container chamber for receiving a medication container and an air passage coupling the medication container chamber with exterior air, and a mouthpiece axially engageable with the inhaler body. The mouthpiece has a mouthpiece chamber and a medication delivery needle communicating with the mouthpiece chamber. The needle extends toward the medication container chamber and has an opening for supplying exterior air and medication from an interior cavity of the medication container, accommodated within the medication container chamber, through the needle and to mouthpiece chamber. In the first position, the mouthpiece engages with the inhaler body with such that the needle is spaced from the medication container, and, in the second position, the needle axially traverses the medication container so that the opening in the needle communicates with the air passage and the interior cavity of the medication container to deliver the medication to the patient. The medication inhaler also includes an air bypass which bypasses the needle and supplies supplemental exterior air to the mouthpiece chamber to increase airflow through the medication inhaler. | 05-06-2010 |
20110046573 | Anti-Drawback Medical Valve - A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. To that end, the valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. In addition, the variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume (i.e., when the valve is in the open mode) that is no less than its closed volume (i.e., when the valve is in the closed mode). | 02-24-2011 |
20110066119 | Anti-Drawback Medical Valve - A medical valve includes a housing having an interior forming an inlet and an outlet. A longitudinally movable member is secured within the interior of the housing. External to the movable member and within the interior is a fluid path. Movement of the movable member controls fluid flow between the inlet and the outlet via the fluid path. The outlet produces no greater than a negligible drawback or positive push during withdrawal of a nozzle. | 03-17-2011 |
20110220106 | MEDICATION INHALER FOR DISPENSING MULTIPLE CAPSULES - A medication inhaler for concurrently delivering multiple doses of medications including an inhaler body having a medication container chamber for receiving a plurality of medication containers and at least one air passage connecting the medication container chamber with external air, a mouthpiece axially engageable with the inhaler body and having a mouthpiece chamber for communication with a patient's respiratory system, and a hollow medication delivery needle communicating with the mouthpiece chamber. A medication delivery needle penetrates the medication containers when the inhaler is actuated and has at least one opening for passing exterior air and medication from interior spaces of the medication containers and through the needle to mouthpiece. | 09-15-2011 |

20090025721 | Powder inhaler devices - An improved inhalation device is provided for facilitating inhalation by a patient of powder medicaments contained in a receptacle. The inhalation device includes a staple assembly comprising a plunger and staple that are securely and robustly coupled to one another. Embodiments of the inhalation device have a cap that prevents or reduces the amount of dust and grime entering into the device. The cap is additionally configured to prevent or reduce inadvertent and unintentional operation of the device. The body portion and first casing portion of certain embodiments of the inhalation device are sealably coupled, restricting or reducing undesirable flow pathways that have an adverse effect on the operation of the device. | 01-29-2009 |

20100249724 | Medical Valve with Distal Seal Actuator - A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the valve has a housing with an inlet and an outlet, a post member moveably mounted within the housing and a distal seal member. The post member moves distally within the housing to fluidly connect the inlet and outlet upon insertion of a medical implement into the inlet. The post member also moves proximally within the housing to fluidly disconnect the inlet and outlet upon withdrawal of the medical implement. The distal seal member has a tapered wall region that surrounds a normally closed aperture. The distal movement of the post member opens the aperture and inverts the tapered wall region. | 09-30-2010 |
20100249725 | Medical Valve with Multiple Variable Volume Regions - A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. The valve has a housing, a valve member with a distal seal having a normally closed aperture, a first variable volume region and a second variable volume region longitudinally spaced from the first. Insertion of a medical implement into the inlet opens the aperture and fluidly connects the valve inlet and outlet via a fluid path. Withdrawal of the implement closes the aperture and fluidly disconnects the inlet and outlet. The first variable volume region contracts and the second variable volume expands upon withdrawal of the implement. Both variable volumes may be part of the fluid path. The fluid path may have a closed volume before insertion of the implement and an open volume when in an open mode. The closed volume may be substantially equal to the open mode. | 09-30-2010 |
