Description

Technical Field

[0001] The present application relates to the technical field of bronchial examination, and in particular to a nasopharyngeal airway for preventing hypoxia during painless fiberoptic bronchoscopy examination. Background Art

[0002] Electronic fiber bronchoscopy is often used in respiratory medicine, emergency department, ICU and other departments to examine the patient's airway condition, etc. However, the invasion of the fiber bronchoscope is a strong stimulation to the patient, which can cause strong discomfort to the patient, resulting in the patient's inability to cooperate or even give up the examination.

[0003] With the development of modern medical technology, more and more patients choose to undergo fiberoptic bronchoscopy or operation under intravenous anesthesia, that is, painless fiberoptic bronchoscopy. Currently, the commonly used management tools for painless fiberoptic bronchoscopy are conventional nasal oxygen tubes, fiberoptic bronchoscopy masks, etc.

[0004] Among them, the application of conventional nasal oxygen tube in fiberoptic bronchoscopy is to place the nasal oxygen tube in one nostril, and the fiberoptic bronchoscope enters from the other nostril and into the glottis to complete the examination. Under the action of intravenous anesthetic drugs, the subject is prone to respiratory depression. In the state of respiratory depression, the patient is prone to tongue posterior fall, so that the oxygen blown into the nasal cavity is likely to be blocked by the tongue and cannot really reach the patient's respiratory tract.

[0005] The fiberoptic bronchoscopy mask is worn on the patient's nose and mouth, and then the fiberoptic bronchoscope enters through a valve hole on the mask and passes through the patient's nasal cavity to complete the examination. However, the valve hole on the fiberoptic bronchoscope mask is fixed, and the facial structures of different patients vary greatly, which can easily lead to a large angle between the mask hole and the patient's nostrils, making it difficult for the fiberoptic bronchoscope to enter the nostrils. Utility Model Content

[0042] See also Figure 1 A nasopharyngeal airway for preventing hypoxia during painless fiberoptic bronchoscopy provided in an embodiment of the present application includes: an insertion tube 10, a camera 20, a depth control jacket 40 and an oxygen source assembly 50; the camera 20 is arranged at the front end of the insertion tube 10; the depth control jacket 40 is sleeved on the insertion tube 10 for controlling the insertion depth of the insertion tube 10; the oxygen source assembly 50 is connected to the rear end of the insertion tube 10.

[0043] The insertion tube 10 may be arc-shaped, which can better fit the nasopharyngeal airway of the patient. The front end of the insertion tube 10 refers to the end thereof that extends into the nasopharyngeal airway.

[0044] In this embodiment, the camera 20 can be a miniature camera, and is electrically connected to the display screen 60 via wires buried inside the insertion tube 10, so as to assist in adjusting the depth of the insertion tube 10 to prevent the insertion tube 10 from being too shallow and failing to pass through the narrow part of the nasopharynx, thereby reducing the possibility of hypoxia in the patient.

[0045] In application, the display screen 60 is disposed at the rear end of the insertion tube 10 and is electrically connected to the camera 20 to facilitate observation by medical staff.

[0046] In this embodiment, oxygen can be delivered to the insertion tube 10 through the oxygen source assembly 50, and only one side of the patient's nasal cavity needs to be occupied during use, which can avoid the patient from suffering from hypoxia and adapt to patients with different face shapes.

[0047] For more specific examples, see Figure 1 and Figure 2 The depth control jacket 40 is an airbag component provided with an inflation port and an deflation port; the inflation port of the depth control jacket 40 is connected to an inflation bag 41; the inflation bag 41 is used to inflate the depth control jacket 40.

[0048] Specifically, in this embodiment, the depth control of the insertion tube 10 is achieved by inflating and deflating the depth control jacket 40. The outer diameter of the depth control jacket 40 is larger than the insertion tube 10 and cannot be inserted into the patient's nasal cavity.

[0049] When the depth control jacket 40 is inflated, the depth control jacket 40 tightens the insertion tube 10, so that the insertion tube 10 and the depth control jacket 40 are fixedly connected. Then, the depth control jacket 40 abuts against the nose wing of the user and cannot enter the nasal cavity, thereby achieving the effect of limiting the insertion depth.

[0050] When deflation is required, the deflation port of the depth control jacket 40 can be opened; when the depth control jacket 40 is deflated, the depth control jacket 40 and the insertion tube 10 are loose, so that the insertion tube 10 can slide relative to the depth control jacket 40, thereby realizing the insertion adjustment of the insertion tube 10.

[0051] Furthermore, the outer circumference of the insertion tube 10 is provided with a friction protrusion 11 for increasing the friction force between the insertion tube 10 and the depth control sleeve 40, so as to ensure that the insertion tube 10 can be fixed when the depth control sleeve 40 is tightened.

[0052] In a more specific embodiment, the oxygen source assembly 50 includes: an oxygen source airbag 51, an oxygen supply tube 52 and an oxygen source generator 53; the oxygen source generator 53 is connected to the oxygen source airbag 51 through the oxygen supply tube 52; the oxygen source airbag 51 is connected to the rear end of the insertion tube 10.

[0053] In this embodiment, the oxygen source airbag 51 can store oxygen, increase the oxygen concentration during the patient's breathing, reduce the probability of hypoxia in the patient, and at the same time, assist ventilation of the insertion tube 10 through the oxygen source airbag 51.

[0054] In one embodiment, it further includes: an artificial nose 30; and an oxygen source air bag 51 connected to the rear end of the insertion tube 10 through the artificial nose 30.

[0055] The artificial nose 30 can filter the exhaled air, etc., and play the functions of cleaning the exhaled air, preventing the spread of infectious gases, and protecting the equipment, etc. The artificial nose 30 can be connected to the insertion tube 10 through a curved adapter 31 .

[0056] In one embodiment, see Figures 1 to 4 , further comprising: an air regulating valve 70; a vent 54 connected to the external air is provided on the oxygen source air bag 51; the air regulating valve 70 is provided on the vent 54 to control the opening of the vent 54.

[0057] The pressure of the oxygen source air bag 51 can be controlled by the air regulating valve 70, thereby adjusting the patient's breathing pressure.

[0058] Furthermore, the air regulating valve 70 includes: a valve body 71 and a movable gasket 72; the valve body 71 is arranged on the vent 54, and an opening 73 is arranged on the valve body 71; the movable gasket 72 can be slidably arranged on the opening 73, and is used to control the opening of the opening 73 to control the opening of the vent 54.

[0059] The valve body 71 is provided with an indication mark indicating the opening direction of the opening 73 .

[0060] The opening 73 may be an arc-shaped channel; correspondingly, the movable gasket 72 is arc-shaped. An adjustment column is connected to the movable gasket 72, which can drive the movable gasket 72 to slide. When the opening 73 is opened, the gas in the oxygen source airbag 51 can overflow through the opening 73; when the opening 73 is closed by the movable gasket 72, the oxygen source airbag 51 is in a closed state, and the pressure of the oxygen source airbag 51 is the maximum.

[0061] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
