摘要:
The present invention relates to a medical device coated with a composition comprising a therapeutic agent and a water soluble additive, which additive is at least one selected from a surfactant and a chemical compound having one or more hydroxyl, amino, carbonyl, carboxyl, acid, amide or ester groups and Log P of the therapeutic agent is higher than Log P of the additive for accelerate releasing of the therapeutic agent from the medical device.

Respiratory therapy apparatus includes an expiratory therapy device (100) that produces an oscillating resistance to breathing. The device has a vibration sensor (20) mounted on its housing (2) that transmits signals to a receiver (200) indicative of operation of the device. An accelerometer (201) is secured to the chest of the patient; this also transmits signals to the receiver (200). The apparatus prompts the user to use the device (100) at each of its different settings and the receiver (300) monitors the effect of the different settings and computes which gives the most benefit. The receiver (300) then prompts the user to select the optimum set ting for further therapy.

A catheter (2) for removing fluid from a patient comprises a tubing (4) having a distal end (6) for insertion into the patient and a proximal end secured to a vacuum control (10) for connection to a vacuum source for effecting removal of the fluid. The vacuum control (10) comprises a first, colour-coded, opaque portion (12) that is gripped by the operator, whereby the degree of suction applied to the catheter tubing (4) from the vacuum source is manually controlled by occlusion of a vent (24) of the first portion (12). A second portion (14) of the vacuum control (10) extends from the first portion (12) and receives the catheter tubing (4). The second portion (14) is substantially transparent and defines an observation chamber to allow the operator to observe the material drawn from the patient.
摘要:
A portable suction device comprising: a gas inlet for receiving pressurized gas from an enclosed source; a gas flow path that extends from the gas inlet to an exhaust; a suction generator that has a suction inlet, the gas flow path extending through the suction generator, such that gas flow through the flow path generates a low pressure at the suction inlet; a collection container with a collection inlet and an outlet that is coupled to the suction inlet; a suction tube that has proximal and distal ends, the proximal end being connected to the collection inlet of the collection container; a valve for controlling gas flow through the flow path, the valve having a stem that is configured to pierce the source with movement of the valve from a closed position.
摘要:
Methods for treating inflammatory pulmonary diseases by administering to the patient an effective amount of one or more pharmaceutical agents are disclosed. The pharmaceutical agents administered can include antibiotics, steroids, NSAIDs, DMARDs, growth factor receptor inhibitors, PI3K inhibitors, neurotransmitter receptor inhibitors, or protease inhibitors. The dose administered is effective to suppress or prevent initiation, progression, or relapses of disease, including the progression of established disease. The pharmaceutical agent is administered to a patient determined to have the disease and at an amount effective to suppress or prevent activity of the disease. The pharmaceutical agent is administered using a transtracheal, transbronchial, or transvascular drug delivery catheter. The pharmaceutical agent can be administered to the patient's pulmonary tissue to suppress reactions in response to bronchial thermoplasty either before, during, or after bronchial thermoplasty.
摘要:
Described here are devices, systems, and methods for positioning a suction catheter in the airway of a patient. The systems may comprise a suction catheter, a delivery device, and/or a stylet. The delivery device may comprise an elongate shaft, an atraumatic distal end, an elongate passageway, and a retention element configured to releasably couple to an endotracheal tube. The suction catheter may be positioned in the elongate passageway, and the delivery device may help advance the suction catheter into the airway of a patient. In some variations, the delivery device may comprise elements configured to release the suction catheter in the airway after positioning.
摘要:
A dilation system includes a balloon catheter and a puncturing assembly. The balloon catheter includes a shaft, a dilator coupled to a distal end of the shaft, and a lumen extending through the shaft and the dilator. The dilator is expandable from a collapsed state to an expanded state. The puncturing assembly includes at least one cutting member. The puncturing assembly is positionable within the lumen of the balloon catheter or along an exterior of the shaft when the puncturing assembly is in a first position. The puncturing assembly transitions to a second position to puncture the lumen of the balloon catheter and/or to puncture the dilator, to thereby drain fluid from the dilator.
