摘要:
A talking tracheostomy tube (10) is shown in the preferred embodiment as including an inner cannula removably received within an outer cannula. The tracheostomy tube further includes, a first cuff (16) for sealing between the outer cannula and the trachea for substantially preventing air introduced through the inner cannula to escape from the trachea through the larynx. Air is introduced into the trachea above the first cuff by ports (40) directionally drilled through the outer cannula and in fluid communication with a secondary passageway formed by and between the inner and outer cannulas. The inner end of the secondary passageway is formed by a sealing obstruction integrally formed in the inside surface of the outer cannula adjacent the inner end for the sealing receipt of the inner cannula. The outer end of the secondary passageway is sealed by a collar (42) integrally formed on the outer end of the inner cannula which abuts and seals within a recess of a collar integrally formed on the outer end of the outer cannula. The tracheostomy tube further includes a second cuff (18) for sealing between the outer cannula and the stoma of the patient for preventing the secondary air introduced through the ports from escaping through the stoma in the neck of the patient.
摘要:
A tracheal tube assembly includes an outer cannula configured to be positioned in a patient airway and an inner cannula configured to be disposed inside the outer cannula. The tracheal tube assembly further includes a flange member secured about the outer cannula, and an outer cannula connector coupled to a proximal end of the outer cannula. The inner cannula includes a compressible proximal end region that is compressed while secured inside the outer cannula connector.
摘要:
The invention relates to tube (1) for endobronchial intubation, comprising an endotracheal portion (100) being designed to be inserted into the trachea (10) of a person, particularly a child, the endotracheal portion (100) being in fluid communication with an inlet (O) at a proximal end (10) of the tube (1) for feeding a ventilation gas (G), particularly air, into the tube (1), an end region (101) of the endotracheal portion (100) opposing the proximal end (2), said end region (101) comprising a first opening (102) for discharging said ventilation gas (G) in one of the main bronchi (11) and a second opening (103) for discharging ventilation gas (G) in the other main bronchus (12), an endobronchial portion (200) being designed to be inserted into said other main bronchus (12), wherein the endobronchial portion (200) is connected to said end region (101) and is in fluid communication with said second opening (103) such that said ventilation gas (G) can be discharged through the second opening (103) into the endobronchial portion (200), wherein the endobronchial portion (200) further comprises an outlet (O') at a distal end (3) of the tube (1), so that said ventilation gas (G) can be discharged through said outlet (O') into said other main bronchus (12), and wherein particularly said endotracheal portion (100) and said endobronchial portion (200) of the tube (1) surround a single lumen (I) for the passage of said ventilation gas (G) through the tube (1) from said inlet (O) to said outlet (O'). According to the invention, the tube (1) comprises a particularly rotatable closure element (300; 400; 500; 600) for closing and opening said first and/or second opening (102, 103).

A loading dilator (20) for positioning a medical apparatus (80) across an opening (94) formed through a body wall of a patient includes a tubular body having a relatively rigid proximal portion and a distal portion, the distal portion including a first relatively flexible segment (32) and a second relatively rigid segment (34). The first segment is axially extendable from a first length that has a greater diameter than the second segment, to a second length having a diameter that does not substantially exceed the diameter of the second segment. A stylet (50) is movable in a passageway of the tubular body between a first position wherein the first segment has the first length, and a second position wherein the stylet distal end exerts an axially displacing force on the second segment such that the first segment is movable from the first length to the second length.

Multi layer endotracheal tube apparatus (800) comprising an outer flexible elongated tube layer (802) having a proximal end (816) and a distal end (818), defining an inner surface (820) therebetween, at least one flexible elongated inner tube layer (804) having a proximal end (822) and a distal end (824), defining an inner surface (828), the distal end (824) of the inner tube layer (804) defining a distal port section (830), the inner tube layer (804) extending along inner length of the outer tube layer (802), the distal end (824) of the inner tube layer (804) detachably coupled along a closed circumference of the inner surface (820) of the outer tube layer (802), and at least one closure mechanism (806) operative to close the distal port section (830), and detach the distal end (824) of the inner tube layer (804) from the inner surface (820) of the outer tube layer.
摘要:
There is provided a reinforced (100) tracheostomy tube (26). Various mechanisms may be used to reinforce the tube, which is reinforced on the upper portion which extends as much as two thirds of the distance from the flange near the proximal end to the distal tip. The tube extends at an angle of from 85 to 120 degrees from the flange to the distal tip and has a length between about 70 and 100 mm.
摘要:
Devices systems and methods are disclosed for preventing or inhibiting secretions from entering the lumen of a functional assessment catheter for the lungs, or removing collected secretions. The catheter comprises an expandable element, a cover, or an internal component configured to prevent or inhibit secretion flow into the lumen. The catheter alternatively or additionally comprises a distal end configured to facilitate air flow, absorb secretions or repel secretions away from the catheter tip. The catheter alternatively or additionally comprises an internal element such as a coilable wire, or an obturator configured to prevent secretions from being drawn into the lumen, or to actively remove the secretions. The catheter alternatively or additionally comprises an element to dry, aerate or aspirate the lung passageways.
摘要:
