Problems solved by technology

[0003] However, the existing nasal cannula for oxygen supply and nasal congestion are not convenient and safe to use. For example, the nasal cannula is easy to fall off when the nasal cannula is used by oxygen patients, and the nasal cannula is a developed type of oxygen supply that cannot guarantee the concentration of oxygen infusion and cannot meet the needs of patients. ventilation pressure
Such as nasal congestion, nasal mask and face mask used by patients, in order to make the patient have a certain air delivery pressure to form a closed oxygen supply, it is necessary to adopt very cumbersome tools and methods to keep the nostrils and air delivery tubes in close fit. Applying a certain amount of force may cause some deformation of the facial body of the patient as the recipient of the force, which will bring unnecessary pain to the patient. The dual-line system of the input and output of the breathing circuit of the ventilator will bring a lot of trouble to the operation. It takes up space and is fixed and cumbersome, and the operation of medical operators is cumbersome, and the patient's activity space is limited

Embodiment 1

[0028] like Figure 1 to Figure 3 As shown, a pressure-controllable respiratory nasal plug includes a nasal plug head 1 and an air source inlet pipe 2, the air source inlet pipe 2 is provided with an air source input port 3, the number of which is one, and the air source The other end of the access tube 2 is provided with a one-way valve 15. When the nasal plug has a gas supply, the one-way valve 15 is always closed under gas pressure or in a natural state. When the equipment fails, there is no gas supply. Pneumatic action, the one-way valve 15 opens and communicates with the atmosphere to supply air to the patient under a small inspiratory pressure to ensure the patient's aerobic respiration. The air source connection tube 2 is also provided with a test pressure connection port 16 for real-time The air pressure in the pipeline is monitored, and the nasal plug head 1 is connected to the air source connecting pipe 2, and the air source connecting pipe 2 is provided with a fixed...

Embodiment 2

[0031] like Figure 4 As shown, a pressure-controllable respiratory nasal plug includes a nasal plug head 1 and an air source inlet pipe 2, the air source inlet pipe 2 is provided with an air source input port 3, the number of which is one, and the air source The other end of the access tube 2 is provided with a one-way valve 15. When the nasal plug has a gas supply, the one-way valve 15 is always closed under gas pressure or in a natural state. When the equipment fails, there is no gas supply. Pneumatic action, the one-way valve 15 opens and communicates with the atmosphere to supply air to the patient under a small inspiratory pressure to ensure the patient's aerobic respiration. The air source connection tube 2 is also provided with a test pressure connection port 16 for real-time The air pressure in the pipeline is monitored. The nasal plug head 1 is connected to the air source access tube 2. The air source access tube 2 is provided with a fixed structure for fitting and f...

Embodiment 3

[0034] like Figure 5As shown, a pressure-controllable respiratory nasal plug includes a nasal plug head 1 and an air source inlet pipe 2, the air source inlet pipe 2 is provided with an air source input port 3, and the number of the air source input port 3 is two. Two gas source input ports 3 are respectively located at the two ends of the gas source inlet pipe 2, and gas can be input through the two gas source inlet ports 3. The side wall of the gas source inlet pipe 2 is provided with a check valve 15. When under gas pressure, or in the natural state, the one-way valve 15 is always closed. When the equipment fails, there is no gas supply. As long as the patient has an inhalation action, the one-way valve 15 is opened under a very small inspiratory pressure to meet the atmosphere. Connected to supply air to the patient to ensure the patient's aerobic respiration. The air source connection pipe 2 is also provided with a test pressure connection port 16 for real-time monitorin...

Abstract

The invention discloses a pressure-controllable breathing nose plug. The pressure-controllable breathing nose plug comprises a nose plug head and an air source connecting-in pipe, wherein the air source connecting-in pipe is provided with one or two air source input openings, the nose plug head is connected with the air source connecting-in pipe, the air source connecting-in pipe is provided witha fixing structure used for fixing the nose plug in an attaching manner, the air source connecting-in pipe is provided with a pressure adjusting valve used for adjusting the air conveying pressure, the pressure adjusting valve sequentially comprises an adjusting sleeve, a pressure adjusting spring, a sealing gasket and a base from top to bottom, a connecting pipe is arranged below the base and connected with the air source connecting-in pipe, air output openings used for exhausting air are formed in the bottom of the base, and a respiratory rate control connector is arranged on the side wall of the base. The nose plug provided by the invention is firm in fixing and comfortable to wear, is safe and reliable, and is an upgraded product of oxygen supply, noninvasive and invasive breathing products in the future.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to a pressure-controllable respiratory nasal obstruction and a single-tube ventilator thereof. Background technique [0002] With the continuous improvement of oxygen supply, non-invasive breathing, sleep breathing and snoring treatment, the requirements for breathing and oxygen supply equipment are also increasing, especially the requirements for closed ventilation nasal congestion combined with man-machine are getting higher and higher, so patients need a safer Effective, convenient oxygen delivery, nasal congestion that can adjust the ventilation pressure is very necessary. [0003] However, the existing nasal cannula for oxygen supply and nasal congestion are not convenient and safe to use. For example, the nasal cannula is easy to fall off when the nasal cannula is used by oxygen patients, and the nasal cannula is a developed type of oxygen supply that cannot g...
