wherein the pre-chamber is provided with a pressure sensor and the processor is configured to receive pressure signal from the pressure sensor to be able to detect air leakage and/or to calculate the amount of air leakage.
Automated optical detection of air leaks in chest tube drainage system
An air leak detection system for chest tube collection systems includes a light emitting element, such as an LED, and a photodetector that can detect reflected light emission generated by the light emitting element. The air leak detection system can include a securement component, such as a transparent clip or adhesive, so that the air leak detection system is compatible with any conventional chest tube collection system. In certain embodiments, the light emitting element is positioned closer to the bottom portion of the water seal tube than the photodetector. In certain embodiments, the photodetector is positioned closer to a bottom of the water seal chamber than the light emitting element. In certain embodiments, the air leak detection system is part of a chest tube drainage system. A method of detecting an air leak in a chest tube collection system is also disclosed.
Systems and methods for controlling operation of a reduced pressure therapy system
Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.
Systems and method for delivery of therapeutic gas to patients, in need thereof, receiving breathing gas from a ventilator that varies at least pressure and/or flow using enhanced therapeutic gas (NO) flow measurement
Provided herein are systems and methods for delivery of therapeutic gas to patients, in need thereof, by receiving breathing gas from a high frequency ventilator using at least enhanced therapeutic gas (e.g., nitric oxide, NO, etc.) flow measurement. At least some of these enhanced therapeutic gas flow measurements can be used to address some surprising phenomenon that may, at times, occur when wild stream blending therapeutic gas into breathing gas a patient receives from a breathing circuit affiliated with a high frequency ventilator. Utilizing at least some of these enhanced therapeutic gas flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives can at least be more accurate and/or under delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.
Occlusive chest wound seal with a one-way vent for preventing and treating tension pneumothorax
A vented chest wound seal for a penetrating chest wound includes a flexible sheet including a top surface and a bottom surface, an adhesive hydrogel layer covering a portion of the bottom surface of the flexible sheet, and a plurality of vent channels. The adhesive hydrogel layer includes an inner perimeter and an outer perimeter, and the outer perimeter forms a continuous perimeter of hydrogel along a bottom surface of the flexible sheet. A plurality of vent channels, each including a first opening to a space inside of the inner perimeter, extend radially outward to an outer terminal end vent to the top surface of the flexible sheet. The outer terminal end is spaced apart from the outer perimeter of the adhesive hydrogel layer towards the central portion of the chamber.
TEMPERATURE MANAGEMENT SYSTEM FOR PATIENTS DURING STATIONARY AND MOBILE ECLS/ECMO THERAPY
The present disclosure relates to a system for temperature management for patients in stationary and mobile ECLS and/or ECMO therapy, with a disposable and a fluid circuit, wherein the disposable comprises a reservoir or bag provided with at least one supply line and a drain line, further comprising a pumping unit element as part of the disposable, by means of which liquid in the reservoir or bag can be pumped through the fluid circuit, wherein in the mounted state of the system all fluid-guiding parts of the system are completely encapsulated and separated from intracorporeal and extracorporeal blood circuit of the patient undergoing the ECLS and/or ECMO therapy.
MEDICAL DEVICE DISLODGMENT DETECTION
In examples described herein, a system includes an elongate member configured to be introduced into vasculature of a patient. The elongate member includes a pressure sensor configured to generate a pressure signal indicative of pressure in the vasculature adjacent the needle. The system includes processing circuitry configured to receive the pressure signal from the pressure sensor, detect, based on the pressure signal, dislodgment of the elongate member from the vasculature, and generate an output in response to detecting the dislodgment of the elongate member from the vasculature.
APPARATUSES AND METHODS FOR DETECTING LEAKS IN A NEGATIVE PRESSURE WOUND THERAPY SYSTEM
Leak location devices and methods of using leak location devices that can be used in conjunction with negative pressure wound therapy systems are disclosed. In some embodiments, a leak location device can include a microphone for detecting sound pressure produced by a leak. Detected sound pressure can be compared to a threshold, which can correspond to background or ambient sound pressure. Background or ambient sound pressure can correspond to sound produced by a negative pressure source. The leak detection device can include a display configured to visually depict the detected sound, and a light source which creates a visual depiction of the coverage angle of the microphone.
INFUSION SYSTEM FOR SHORT-LIVED RADIOPHARMACEUTICALS
A non-surgical method of delivering a liquid radioactive solution from a source to a recipient comprising the steps of: determining a desired recipient level of radioactivity and recipient volume of the radioactive solution to be delivered to the recipient, providing a first valve having a waste position and a recipient position, providing a bolus conduit, a waste conduit and a recipient conduit, each conduit having a valve end being connected to said first valve, so that the first valve can establish a waste flow path in the waste position and a recipient flow path in the recipient position, the recipient flow path being different from said waste flow path, the bolus conduit comprising a measuring section and an internal volume, the internal volume being approximately equal to the desired recipient volume of the radioactive solution to be delivered to the recipient, arranging said first valve in the waste position, transporting a first amount of said radioactive solution through said waste flow path, the first amount of said radioactive solution having an initial level of radioactivity that is at least approximately equal to or higher than the desired recipient level of radioactivity and an initial volume that is larger than the internal volume of said bolus conduit, providing a radiation detector, the radiation detector being operable to measure a level of radioactivity of the radioactive solution in said measuring section, measuring a reference level of radioactivity of said radioactive solution present in said measuring section, wherein when the reference level of radioactivity is approximately equal to an injection level of radioactivity, the method further comprises the steps of: arranging the first valve in the recipient position, and transporting the radioactive solution present in the bolus conduit through the recipient flow path.
