3 results about "End tidal" patented technology

The utility model discloses a kind of pipeline kits for collecting end tidal carbon dioxide while inhaling oxygen, it is related to oxygen inhalation tube technical field, the utility model, including oxygen pipe and shell, shell inside is connected with heat conduction cylinder, and heat conduction cylinder inside is connected with heat conduction plate, heat conduction cylinder outside is sleeved with electric heating rod, heat conduction cylinder and shell back side side are penetrated with temperature sensor;Shell top side is penetrated with support, and support outer part is respectively sleeved with sealing sleeve and moisture absorption sleeve.The utility model is set through heat conduction cylinder, electric heating rod, heat conduction plate and temperature sensor, electric heating rod starts after heat conduction cylinder and heat conduction plate are heated, pass through multiple heat conduction plate staggered distribution and prolong the time of oxygen passing through heat conduction cylinder, to make oxygen can have more time to be heated, and the temperature before oxygen enters oxygen pipe is detected by temperature sensor, avoid that oxygen temperature is too high and scalds patient respiratory tract;It improves heating efficiency and ensures oxygen warm and comfortable, and avoid that temperature is too high and appears scald or discomfort.

A system (100) and a method (200) for providing intermittent hypoxia using sequential gas delivery to a subject are disclosed. The method (200) comprises the step (204) of inducing a normoxic end tidal partial pressure of oxygen using a sequential gas delivery system within a first specific number of breaths for a first duration and the step (208) of inducing a hypoxic end tidal partial pressure of oxygen using the sequential gas delivery system within a second number of breaths for a second duration and repeating the steps for a target number of cycles until a therapeutically effective dose of intermittent hypoxia is attained. The sequential gas delivery system (100) may control the end tidal partial pressure of carbon dioxide simultaneously and independently of the end tidal partial pressure of oxygen. The method (200) may be applied in the treatment of a pathological condition in a subject or for improving a health condition of a subject.

The invention relates to the technical field of oxygen inhalation masks, and discloses an oxygen inhalation mask capable of adsorbing and detecting end-tidal carbon dioxide, which comprises an oxygen inhalation mask body, the oxygen inhalation mask body is worn on the face of a patient through an elastic band, a nose bridge buckle opening is formed in the oxygen inhalation mask body, and the oxygen inhalation mask body is made of polyethylene. A sealing layer is arranged on the side, facing the skin, of the oxygen inhalation mask body, and an oxygen supply mechanism for providing breathing oxygen is arranged on the oxygen inhalation mask body. According to the breathing mask, the in-human sticky frame is stuck to the middle of a wearer, and the swing film arranged on the in-human sticky frame generates two different swing states during inspiration and exspiration, namely, during inspiration, the swing film is pressed downwards, and oxygen cannot be prevented from being inhaled into the nasal cavity; and during expiration, the swinging film jacks up and expands the opening, so that exhaled airflow can be completely contained in the sticking frame in the human body, and exhaled air cannot be leaked, thereby being beneficial to improving the accurate detection of end-expired carbon dioxide in the exhaled air.
