Description

Amplified airway examination system

The present invention relates to an expanded respiratory examination system; and more particularly to an intubation assist system for timely observation and accurate airway examination.

In medical technology, intubation is required for special patients. The intubation referred to in this case refers to the insertion of a breathing tube, also known as an "intratracheal cannula", so that oxygen can be quickly administered; see Figure 10. As shown, the breathing tube 70 is mainly accessed from the patient's mouth or nasal cavity, and then the esophagus 82 is pushed away and the escaping 80 is pushed into the trachea 81. The breathing tube 70 can be inflated and erected in conjunction with the inflation of the inflating unit 71 so as to be dense. It is fitted to the peripheral wall of the trachea 81, and the breathing tube 70 is connected to a respirator (not shown) to assist the patient in breathing.

However, when intubating, it is necessary to use an auxiliary tool, that is, the augmented respirator is inserted from the mouth to push the patient's epiglottis 80 away, so that the breathing tube 70 can be safely and quickly inserted, and then the augmentation is performed after the intubation is completed. Respirator removal; currently a more common augmented respirator as shown in Fig. 11, the augmented respirator 90 has a grip 91 and a tab 92, and is connected at one end of the augmented respirator 90. The screen 93 has a bracket 94 with a roller 95 under the screen 93. When the augmented respirator 90 is used, the hand grip 91 extends the tab 92 from the patient's mouth for the purpose of expanding the trachea. The end of the piece 92 is provided with a photographic head, and the condition of the front end is displayed on the screen 93 to facilitate the insertion of the cannula. Although the movable bracket 94 is provided under the screen 93, the screen 93 can be conveniently pushed to the most convenient. The position of the viewing, but in the operation of the operation, in addition to the current operation of expanding the trachea on the one hand, the medical practitioner must turn his head and look at the information of another screen 93, combined with the contents of the two to jointly achieve the best intubation work. State, but when the surgeon performs surgery or instrument operation, on the one hand, he has to look down at the current state of the human body, and he has to look up or turn around to watch the information on the screen 93, which is very inconvenient and easy to fatigue. Moreover, the roller 94 under the bracket 94 The space of the frame makes the adjustment position limited, and it is very dangerous to trip over the doctor or the nursing staff. In addition, if a senior medical practitioner is required to guide the patient, the senior medical practitioner must instruct the information on the screen, and On the one hand, it is necessary to guide the surgery of new medical practitioners. It is more busy and difficult to go back and forth. An oversight will cause medical regrets and is its main drawback.

Referring to Fig. 12, it is a more advanced amplifying respirator 90', including a grip 91' and a tab 92' having a small screen 93', which solves the problem that the medical practitioner does not need a big action to raise or turn the head. Troubled, but placing the screen 93' on the grip 91' is also a risky design, because the grip 91' is for the medical practitioner to hold the force, so the grip 91' itself will be shaken during operation, while watching The screen 93' is not very convenient, and the small screen 93' has a small viewing angle range, and is easily reflected by the light above the roof. If necessary, it is necessary to take the time to temporarily put down the operation, use the other hand or ask someone to assist. Adjusting the angle of the screen 93' is actually not very convenient in practical operation; at the same time, since the augmented respirator 90' with the small screen 93' is more expensive, it is mostly reused, but the small screen 93' Above the grip 91', so the bleeding from the patient's mouth during surgery often splashes on the small screen 93' and the grip 91', which is likely to cause bacterial contamination. Although it will be disinfected during repeated use, it will still cause safety concealment. .

The main purpose of the invention is to make the use of the invention more convenient and precise, and An expanded airway examination system that can be used to discard some components, including an augmented respirator and a head-mounted video unit and an optical system; wherein the augmented respirator is integrally formed of a plastic that is sterilized. And the curved insert; the image taken by the augmented respirator can be transmitted to the video unit through the connecting unit, and the image is displayed on the optical system; when the user holds the amplified respirator to insert the patient During the treatment of the tube, the amplified respirator will clearly inject the immediate image of the intubation operation back to the video unit assembly and the optical system; the user can not only see the surgical site in front of the eye, but also the operating image of the augmented respirator is the same The orientation is displayed on the optical system to allow the practitioner to concentrate on the operation and reduce accidents; and after use, the amplified respirator can be discarded for better health care.

In order to achieve the above object, the present invention can be achieved in the following manner: an amplifying respirator comprising a grip and a curved insert, and the grip and the insert are integrally formed of a sterilized plastic, wherein The end of the insert has a protruding pressing piece, and a slot for inserting the buzzing tube is provided on the side of the inserting piece, and a video hole and an illumination hole penetrating through the grip are provided inside the inserting piece; The image processing controller and the battery are mounted on the inside of the grip, and an image sensor and a light source are respectively disposed on the end of the video channel and the illumination channel of the grip, and the end of the image sensor can be provided with an optical lens; a connecting unit transmits the image taken by the augmented respirator to the video unit; a video unit has a head frame, which can be worn on the head of the doctor, and the head frame is pivotally connected to one side of the head frame a frame having a receiving slot, an image circuit board and a battery are disposed in the receiving slot, and a socket and a control switch are protruded outward; and the outer end of the frame (ie, facing the user's face) is pivoted Have an image display The lens assembly box is further provided with an adjustable orientation camera lens at the outer end of the lens assembly box, which can transmit the current scene to a remote or video recording, and is further disposed under the lens assembly box.
