The electrodes are configured to (i) attach to a patient, and (ii) receive a first electromyographic signal from the patient. The control module is connected to the electrodes. The control module is configured to (i) detect the first electromyographic signal, and (ii) generate a first voltage signal. The physical layer module is configured to: receive a payload request from a console interface module or a nerve integrity monitoring device; and based on the payload request, (i) upconvert the first voltage signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the sensor to the console interface module or the nerve integrity monitoring device.
Wireless stimulation probe device for wireless nerve integrity monitoring systems
A stimulation probe device including a first electrode, a stimulation module, a control module and a physical layer module. The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.
FLOW-OPTIMIZED SUPPLY TO A BALLOON ELEMENT THAT SEALS DYNAMICALLY AND IN SYNC WITH ORGANS
The invention relates to a device for the dynamically adapting sealing of an organ or a body cavity, e.g. the windpipe (trachea) of an intubated and ventilated patient, wherein the sealing balloon element is produced via particularly rapid shifting of filling medium from an extracorporeal reservoir or an extracorporeal source to the sealing balloon, and wherein, in the dynamic sealing of the trachea according to the example case, a balloon-type foil body preferably formed with residual material in the diameter, i.e. exceeding the tracheal diameter, is in contact with the inner wall of the trachea in a sealing manner and with a pressure that is as constant as possible, wherein fluctuations in the balloon volume, caused by fluctuations in the intrathoracic pressure relating to the mechanics of breathing, are compensated as quickly as possible by supplying volume from an extracorporeal reservoir or an extracorporeal source, and the tracheal secretion sealing of the balloon is thereby kept continuous. This is both made possible by a sufficiently high-volume supply of the balloon filling medium to the cuff, and also prevents steps, gaps or ridges in the supply system, whereby volume flow directed towards the balloon can be minimised, which is crucial for a rapid-as-possible stabilising of the filling volume in the balloon, in particular with small pressure differences between 15 and 30 mbar that are driving the volume flow.
Airway management device and method of manufacture
An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.
ENDOTRACHEAL TUBE
An endotracheal tube (1) comprises a tubular body (2) having a form of a flexible curved transparent tube with open proximal (3) and distal (4) ends, a connector (7) mounted on the proximal end of the tube and served for attaching a tube cavity to a ventilation device, an inflatable cuff (9) having a cavity, said inflatable cuff fixed hermetically around the distal end of the curved tube and configured to be inflated to seal the cuff against a wall of a patient's trachea and to hold the distal end of the endotracheal tube in the desired position in a patient's larynx, a longitudinal air supply channel (10) in the wall of the tubular body, said channel being in communication with the cavity of the inflatable cuff, a sealed balloon (12) having elastic walls and configured to maintain and monitor pressure in the cuff cavity, the sealed balloon connected to an air supply port, and connected via a catheter (13) to the longitudinal air supply channel to supply an air into the cuff cavity, and a mark (14) made on the surface of the tube from the side of the proximal end at a distance of 2.5-3 cm from the inflatable cuff, wherein the inflatable cuff comprises two layers (15,16), wherein an outer layer (15) of the inflatable cuff is made of a porous biocompatible polymer material and serves as a depot for input and hold the drug in the pores of the polymer material and remove the drug from the pores of the zone of contacting of the cuff with the trachea when the cuff is inflated providing infusion of the drug into the tracheal mucosa.
System and method for an endotracheal tube cuff assembly
A cuff assembly for an airway tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the airway tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A pressure controller independently adjusts the pressure within the inner cuff and the outer bladder. A secretion collection receptacle is formed by the cuff assembly and is evacuated via a suction catheter or channel.
ENDOTRACHEAL DEVICE FOR MECHANICAL VENTILATION OF A PATIENT
An endotracheal device for mechanical ventilation of a patient includes a ventilation tube and a barrier. The ventilation tube includes a distal part, with a distal end, intended to be inserted into an airway of a patient, and a proximal part, with a proximal end, intended to be connected to a ventilation machine. The barrier is made of solid viscoelastic material, covers the ventilation tube in the distal area, and is configured to occupy, when inserted, the subglottic region, as well as the glottic region and also the supraglottic region of the larynx of the patient, for which reason the barrier has a variable cross section along the length thereof. The device provides greater safety and a lower incidence of complications in mechanical ventilation of patients.
