Disclosed herein is a method for monitoring and management of a patient's oxygen therapy and breathing. Accordingly, the method may include a step of receiving, using a communication device, at least one sensor data from a sensor device. Further, the method may include a step of analyzing, using a processing device, the at least one sensor data. Further, the method may include a step of generating, using the processing device, a notification based on the analyzing. Further, the method may include a step of transmitting, using the communication device, the notification to at least one external device. Further, the method may include a step of storing, using a storage device, the notification.

Devices, systems for localized delivery of a chemotherapy, hormonal therapy or targeted drug/biologic therapy to a target tissue area of an internal body organ of a patient. A catheter 10 forms a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin. The drug may saturate the target tissue area and pass therethrough into the lymphatic system or interstitial space, which may serve as a reservoir of the drug for continued therapeutic treatment after withdrawal of the catheter. The chamber is evacuated at the end of the treatment session.

There is provided system for monitoring spontaneous breathing of a mechanically ventilated target individual, comprising: a feeding tube for insertion into a distal end of an esophagus of the individual, sensor(s) disposed on the feeding tube at a location such that the sensor(s) is located at the distal end of the esophagus of the individual when the feeding tube is in use, wherein the sensor(s) is positioned for sensing values by contact with the tissue of the esophagus including a lower esophageal sphincter (LES) and/or tissue in proximity to the LES, and code for computing an indication of a frequency band of diaphragm movement of the individual according to an analysis of values sensed by the sensor(s), and for adjustment of parameter(s) of a mechanical ventilator for mechanically ventilating the individual, wherein the instructions for adjustment are computed while the feeding tube is in use.

Disclosed is a three-cavity flushable fish mouth laryngeal mask airway catheter, including a cover, the cover is provided with a respiratory chamber for communicating with a respiratory tract and a digestive chamber for communicating with a digestive tract; the digestive chamber is provided with a digestive opening for communicating the digestive chamber and the digestive tract; a peripheral wall of the digestive chamber is tapered from an end away from the digestive opening to the digestive opening; an edge of the digestive opening includes a plurality of protrusions; and the plurality of protrusions are configured to be close to each other due to a squeezing force during a process of inserting the three-cavity flushable fish mouth laryngeal mask airway catheter into a throat to narrow the digestive opening.

An apparatus to remove liquid from a ventilation system can include a housing, a first port extending into an interior volume of the housing and a second port extending toward the first tube, into the interior volume, separated from the first port by a gap that is at least 5 mm in length, such that ventilating fluid transfers from the first port to the second while secretions and condensate escape through the gap, to be trapped in the housing. The first port joins with a ventilator. The second port joins with an intubation tube coupled to a tracheostomy or endotracheal tube. An extraction port is in a floor of the housing so that accumulated liquids in the housing can drain downward and out the extraction port, while minimizing positive end expiratory pressure loss in the ventilation system, and without exposing caregivers to biological material in the drained liquid.

a dilatable balloon catheter, comprising: a guide wire inserted and disposed in the inside of the catheter, an operation portion is fixedly connected to one end of the catheter, a balloon is disposed at the outer side of the catheter remote from the operation portion, the lumen of the catheter and the inner cavity of the balloon are connected by a communication structure provided on the catheter, the guide wire includes a first guide wire and a second guide wire which are separated from each other, the rear end of the first guide wire is connected to insertion-extraction structure in the rear end of the operation portion, the second guide wire is fixed to the inside of the catheter by a fixing process. The guide wire of the dilatable balloon catheter and the liquid injection lumen can share the same lumen, greatly reducing the diameter of the catheter in the present invention, so that the dilatable balloon catheter can be inserted into a narrow duct or lumen that needs to be expanded in human body through an device channel of an endoscope, and realize visualization operation.

Disclosed is a closed suction catheter for removing respiratory secretions secreted from a patient's airway, the closed suction catheter including: a tube (10) covered with a flexible outer skin (20); a suction controller (30); and a connection adaptor (40), wherein the suction controller (30) includes a main body (31) being connected to the flexible outer skin (20) by a coupling ring (32) and including: two tube holes (311 and 312) formed in the main body (31); a longitudinal groove (313) formed between the tube holes (311 and 312), with a roller (33) installed in the groove (313); a guide portion (315) formed on a side wall (314) of the groove (313); and a bottom surface (316) inclindly formed at the main body (31) with the tube (10) placed on the bottom surface (316), such that an opening ratio of the tube (10) is controlled by movement of the roller (33).

An apparatus for performing a balloon dilation procedure at the site of a stenosis or for deploying a stent in a patient, the apparatus including a single lumen catheter having a proximal end and a distal end, and a high pressure balloon attached to the distal end of the catheter. The high pressure balloon is fabricated from a semi-compliant material that has an average rated burst pressure of between about 15 and about 27 atmospheres of pressure and exhibits a dumbbell-shaped outer periphery when inflated to a first atmospheric pressure and a substantially linear outer periphery when inflated to a second atmospheric pressure.
