Problems solved by technology

Because the catheter needs to pass through the glottis before it is sent into the bronchus, and because most bronchial examinations are performed without anesthesia, the patient feels a lot of foreign body during the examination and operation; Damage to tracheal tissue due to improper operation

Embodiment 2

[0039] Such as Figure 4 As shown, there are also two support bars 2 in this embodiment. One support bar is solid with an outer diameter of 1.0 mm, and the other support bar 2 is a hollow structure and serves as a trachea 4, that is, a support bar. Combined with the inflation tube; the outer diameter of the support bar of the hollow structure is 1.2mm, the inner diameter is 0.8mm; the lower port of the support bar 2 is inserted into the cavity of the airbag 3, and the upper end extends outward , The upper port is connected to the inflation source.

[0040] The rest is the same as in Example 1.

Abstract

The invention relates to a bronchoscope introduction cannula. The bronchoscope introduction cannula comprises an intubation tube (1) and is characterized in that the intubation tube (1) comprises a first end tube (11) and a second end tube (12) which are arranged at two end openings respectively, the first end tube (11) and the second end tube (12) are connected through a hollow flexible membranesac (13), and at least two support bars (2) which can be deformed in the length direction are also connected between the first end tube (11) and the second end tube (12) at intervals. Compared with the prior art, the bronchoscope introduction cannula has the advantages that the foreign body sensation of a patient is greatly relieved, and the surgical comfort of the patient is greatly improved; thebronchoscope introduction cannula is particularly suitable for the surgical operation and detection of bronchial bleeding without ventilator support under non-general anesthesia.

Description

Technical field [0001] The invention relates to the field of medical devices, and in particular to a bronchoscope introduction sleeve. Background technique [0002] CNCN93229374.3 discloses a "right-side single-lumen bronchial catheter", which consists of a tracheal intubation connector, a tracheal catheter, a cuff, a side hole and a valve. CN95203456.5 discloses a "transnasal tracheal catheter", which comprises a catheter, a plastic film cuff mounted on the catheter, and a free inflation tube similar to the plastic film cuff. Another example is the "New Disposable Visual Tracheal Intubation" published by CN201520907883.4, which is mainly composed of the intubation body, airbag mechanism, image transmission mechanism, and light transmission mechanism. [0003] There are also many patented technologies and existing technologies in which the endoscopic catheter is composed of the same elastic plastic tube with the same diameter. Because the catheter needs to go through the glottis ...
