摘要:
The present disclosure pertains to a nasal therapy system. In one embodiment, the nasal therapy system includes at least one flow sensor is configured to determine a flow rate of a gas flow to be provided to a patient via a nasal interface; at least one pressure sensor configured to determine an amount of pressure of the gas flow based, at least in part, on a prescribed pressure; a valve operable to control an amount of the gas flow being provided to the nasal interface; and a controller configured to determine a flow rate difference between a prescribed flow rate and the flow rate, and cause an output setting of the valve to be adjusted to control the amount of the gas flow being provided to the nasal interface such that the amount of the gas flow is maintained at the prescribed flow rate and the prescribed pressure.
摘要:
A patient circuit of a ventilation system, such as a non-invasive open ventilation system, wherein the patient circuit comprises a nasal pillows style patient interface that incorporates at least one "Venturi effect" jet pump proximal to the patient. The patient circuit further comprises a pair of uniquely configured 3-way connectors which, in cooperation with several uniquely configured tri-lumen tubing segments, facilitate the cooperative engagement of the patient interface to a ventilator of the ventilation system.

A nasopharyngeal catheter for administration of oxygen and monitoring for a patient includes a first catheter having a first lumen, and a second catheter having a second lumen. The first end of the first catheter is operably connected to an oxygen source, the second end of the first catheter operably runs to the posterior oropharynx of the patient, and the first lumen is adapted for oxygen delivery. The second catheter is attached to the first catheter, and the second lumen is adapted for capnography monitoring. The nasopharyngeal catheter further includes an in-line pressure release valve placed proximate to the first end of the first catheter for monitoring pressure of a patient. The nasopharyngeal catheter may also include a pH monitoring sensor for monitoring breath and risk of gastric content translocation of a patient.
摘要:
Systems, methods, and devices for humidifying a breathing gas are presented. The system includes a base unit, a vapor transfer unit, a nasal cannula, and a liquid container. The base unit includes a blower. The vapor transfer unit is external to the base unit and includes a gas passage, a liquid passage, a gas outlet, and a membrane separating the gas passage and the liquid passage. The membrane permits transfer of vapor into the gas passage from liquid in the liquid passage. The nasal cannula is coupled to the gas outlet. The liquid container is configured to reversibly mate with the base unit.
摘要:
System and method for monitoring respiratory quantities during the administration of oxygen at various concentrations by nasal cannulas, in particular by means of an HFNC (High Flow Nasal Cannula) apparatus (100) or a CPAP (Continuous Positive Airway Pressure) apparatus (200), which system and method provide the use of: - a first flow detector (21 or 1021, DPT-A) configured to measure a delivered flow (Φ HFNC_PNT-A or Φ ΟΡΑΡ_ΙΠ_ΡΝΤ-Α ) of oxygen at different concentrations administered upstream the nasal cannulas (105 or 205); - a second flow detector (22 or 1022, DPT-B) configured to measure a residual flow (Φ Mask_PNT-B or Φ ΟΡΑΡ_out_ΡΝΤ-Β ) that crosses an oro-nasal mask (3) worn above the nasal cannulas (105) of an HFNC apparatus (100) or expiratory branch (206) of the ventilation circuit in the case of a CPAP apparatus (200); - a pharyngeal catheter (4) associated with a pressure transducer (DPT-D) for measuring pharyngeal pressure (Pphar); - an esophagus-gastric catheter (5) associated with two pressure transducers (DPT-E, DPT-F) for measuring the esophageal pressure (P Es ) and gastric pressure (P Ga ); - a catheter associated with a pressure transducer (DPT-C) configured to measure the internal pressure of the oro-nasal mask (3) (P Mask ) or a circuit catheter (1006) associated with a pressure transducer (DPT-C ) configured to measure the pressure inside the ventilation circuit near the nasal cannulas (205) (P Circ ); - an oscilloscope (7); - a processing unit (10 or 1010) for the determination of parameters representative of respiration and/or pulmonary mechanics.
摘要:
A gas sensor kit includes a gas sensor that measures a gas concentration of an exhalation gas of a subject and a gas supply unit that supplies a therapeutic gas, supplied through a tube, to the subject. In the gas sensor, the gas sensor has a convex portion that is supported when connected with the gas supply unit, and the gas supply unit has at least one locking claw that supports the convex portion when connected with the gas sensor.
摘要:
A head positioning aid (100) includes positioning members (102) secured to a headwear member (110). The positioning members maintain an infant's head in midline. At least one strap (120) on the headwear member secures the head positioning aid to an infant's head. Optional securing devices (200) secure and orient tubing (172, 174) for CPAP and nasal cannulas to the headwear member.
摘要:
An apparatus for delivering a flow of gas, has a housing 3202' with a recess, and an outlet port 3210' for a flow of gas. The recess is defined by at least one wall 3256, 3262 that is substantially continuous, gas impermeable, and unbroken, other than a gasflow passage from the recess to the outlet port of the housing.
摘要:
A disposable nasal air moisturizing device is removably attached to a nasal cannula to release a moisturizing liquid into a breathing gas and a patient's nasal airway. The intranasal sponges and moisturizing liquid prevents and treats both abrasions from the nasal cannula and excessive drying of the mucosa. This reduces the incidence of nosebleeds in patients using supplemental nasal oxygen.
摘要:
An apparatus including a tubular channel having a pathway extending between a proximal end and a distal end of the tubular channel. The proximal end is configured to connect directly or indirectly to an end tidal CO 2 monitor. The distal end has an opening. The apparatus further includes a detection member including a chamber disposed in fluid communication with the pathway of the tubular channel such that gas entering the tubular channel via the opening on the distal end passes into the chamber. A detection element is disposed within the chamber and includes a component that is sensitive to one or more systemic biomarkers such that, upon exposure to a predetermined concentration level of the one or more systemic biomarkers contained in the gas, a state of the detection element experiences a permanent alteration and the detection member indicates that the predetermined concentration level of the one or more systemic biomarkers is present in the gas.
