Description
Technical Field
The utility model relates to the technical field of autogenous cutting cannulas.
Background
Tracheotomy establishes an artificial airway, and is an important measure for solving respiratory obstruction and improving ventilation function of critically ill patients. However, after the autogenous cutting, the warming, humidifying and purifying effects of the upper airway on the inhaled gas are lost, so that respiratory mucosa is easy to dry, sputum is easy to thicken, sputum embolism is formed, the defending function of a respiratory system is reduced, and conditions are created for pathogen invasion. Therefore, the reduction of the loss of the moisture in the respiratory tract and the enhancement of the airway humidification of a patient after the tracheotomy are important measures for keeping the airway moist, the sputum dilution and the respiratory tract unobstructed, and are also key for reducing the occurrence of pulmonary infection.
Currently, the accepted nasal oxygen cannula consists of a gas delivery tube, a tracheal cannula interface and an open splash cap. The gas enters the lung of a patient along with the gas delivery pipe and then is exhaled through the outlet, because the individual difference of the patient, the required flow velocity gas delivery port cannot be met, and partial gas is required to be inhaled from the outlet when the patient inhales, so that the moisture molecular weight in the gas is reduced, the saturated humidity of the water molecules in the gas is reduced, the airway humidification effect of the patient cannot be effectively ensured, sputum scab and tube blockage phenomena often occur in the tracheal intubation, and the life of the patient is endangered.
Disclosure of utility model
The utility model aims at solving the technical problems, and provides the nasal oxygen cannula applied to the autogenous cutting patient, which ensures the smooth air intake of the original air delivery side, and improves the humidity of the inhaled air by additionally arranging the detention tube on the exhalation side, so that the sputum of the patient is diluted and is easy to discharge.
The utility model adopts the technical proposal that a nasal oxygen cannula applied to an autogenous cutting patient is provided, which comprises
An endotracheal tube interface configured for sealed conductive connection with an endotracheal tube worn in the patient's autogenous cutting section;
The device comprises a central tube, a cap, a first interface, a second interface, a cap and a cap, wherein one end of the central tube is in sealing conduction connection with the trachea cannula interface, the cap is connected to the sputum suction port, one end of the central tube, which is close to the trachea cannula interface, is provided with the first interface, one end of the central tube, which is close to the sputum suction port, is provided with the second interface, and the side wall of the end of the central tube, which is close to the sputum suction port, is provided with the second interface;
One end of the air pipe is connected with the first interface in a sealing way, and the other end of the air pipe is in butt joint with external air inlet equipment;
One end of the detention pipe is connected with the second interface in a sealing way, and the other end of the detention pipe is communicated with the outside atmosphere.
Further optimizing the technical scheme, the detention tube of the nasal oxygen cannula applied to the autogenous cutting patient is a settable telescopic hose.
Further optimizing the technical scheme, the central tube of the nasal oxygen cannula applied to the autogenous cutting patient is in axial rotatable sealing plug-in connection with the tracheal cannula interface.

Further optimizing this technical scheme, the inner wall of the detention pipe of a nose oxygen pipe that is applied to the autogenous cutting patient is coated with hydrophilic coating.
Further optimize this technical scheme, a material that is applied to the detention pipe of aerobics patient's nose oxygen pipe is PET, and the inner wall of detention pipe is corona treatment's roughness.
In the technical scheme, the detention pipe can form a section of air passage which is relatively closed, heat and moisture in the gas exhaled by a patient are collected and reserved, the evaporation of the moisture is reduced, no stimulation is caused to the respiratory tract, and the gas inhalation is closer to a physiological state. The detention pipe is crisscross with the gas-supply pipe and sets up, and all is less than 90 degrees with the angle of center tube in inhaling phlegm mouth same direction, and the air current gets into and the exhaust pressure is less relatively, has guaranteed simultaneously to inhale phlegm mouth and trachea cannula interface and is in coaxial center, does not disturb patient's sputum aspiration. The distance between the gas pipe and the trachea cannula interface is closer than that between the gas pipe and the trachea cannula interface, oxygen in the gas pipe is preferentially inhaled during inhalation, and then the retention gas exhaled from the interior of the retention pipe is supplemented, so that the utilization rate of the oxygen can be ensured.
The structure of the detention pipe is set as a settable telescopic hose, so that the length of the detention pipe can be adjusted through the telescopic setting of the structure, and the breathing dead space of a proper patient can be adjusted according to the vital capacity, the gas transmission flow, the humidity and the blood gas analysis index of different patients.
The central tube is connected with the trachea cannula interface in a rotatable sealing and inserting mode, and the central tube adopts a two-section rotary sealing and inserting structure, so that the degree of freedom of relative rotation of the gas transmission tube, the central tube, the detention tube and the central tube can be realized, a patient can change along with the state of an illness and adjust the body position, and the two pipelines can be respectively rotated to proper positions, so that the trachea cannula is more convenient to wear.
The inner wall of the detention pipe is coated with a hydrophilic coating, or the inner wall adopts a rough surface treated by a corona process, so that the adsorption rate of the expired water vapor can be improved, the condensed water vapor can present a water film with larger surface area on the inner wall of the detention pipe, but not in the form of water drops, and thus, when the gas is expired from the detention pipe, the recycling of the water vapor is easier to realize.
