The traditional single-lung ventilation anesthesia mode is a single-lung ventilation mode inserted into a double-cavity bronchial catheter, the technology can realize simultaneous separated ventilation of two lungs, can effectively prevent various secretions from overflowing from an affected side lung to a healthy side lung, is relatively applicable to patients with lung dampness lesion and empyema, and has a relatively wide application range in clinic. However, this technique is difficult to intubate, and it takes a long time to intubate and position, and has many complications in throat, vocal cords, and bronchi. In recent years, the development of the bronchial occlusion technology is more and more rapid, and the application of the bronchial occlusion device in the intrathoracic operation is gradually started. The traditional bronchial catheter has the pipe diameter of 6Fr, the pipe diameter is too thin, the effect is not good when a sputum aspirator smokes, and the time is too long when patients feel suffocated and deflate.

In the disposable blocking bronchial cannula disclosed in the prior patent CN 205460314U, a syringe joint with a blocking head arranged at the upper end of a bronchial catheter cannot realize sealing, and when a sputum aspirator is connected in the operation process, the operation process is complex and the connection with the sputum aspirator is inconvenient; the buckle in this application is single buckle, and the buckle is the plastics material, and at the operation in-process, the buckle is fixed insecure with trachea cannula, takes place to shift easily, influences the operation effect.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a convenient operation fixes a position accurate bronchus plugging device.

The utility model adopts the following technical scheme:

a bronchial occluder comprises a bronchial catheter, wherein a cuff is arranged at the air outlet end of the bronchial catheter, an inflation piston is arranged close to the air inlet end of the bronchial catheter and is communicated with the cuff through an inflation tube, a composite joint is arranged at the air inlet end of the bronchial catheter and is of a three-way structure, the upper port of the composite joint is provided with a plugging head, the lower port of the composite joint is connected with the bronchial catheter, and the side port of the composite joint is externally connected with a sputum aspirator; the middle part of the bronchus is provided with a buckle.

Compared with the prior art, the device has the beneficial effects that:

the device can be better applied to the external plugging of the bronchus on the traditional basis, so that the operation of the bronchus plugging is simpler, and the positioning is more accurate.

Further, the following technical scheme is adopted:

the buckle includes buckle one and buckle two, and buckle two all is U type structure, and the symmetry is provided with the arch on the inner wall of every buckle, connects through the connecting piece between buckle one and the buckle two.

The connecting piece is rectangular shape, and the both ends of connecting piece set up to globular end respectively.

The inflation tube is positioned inside the bronchial tube.

The inner diameter of the bronchial tube was set at 10Fr (3 Fr =1 mm).

The buckle material is silica gel.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses be applied to the bronchus shutoff, through this technical improvement on traditional plugging device, the better bronchus shutoff that carries on, the shutoff in the shutoff was handed over to the outside of tubes can be more simple and convenient in the operation, and the location is more accurate, fixes more stably, conveniently inhales the phlegm more.

Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

A bronchial occluder comprises a bronchial catheter 2, wherein a cuff 1 is arranged at the air outlet end of the bronchial catheter 2, an inflating piston 7 is arranged at the air inlet end close to the bronchial catheter 2, and the inflating piston 7 is communicated with the cuff 1 through an inflating tube 6 penetrating through the bronchial catheter 2.

A composite joint 8 is arranged at the air inlet end of the bronchial catheter 2, the composite joint 8 is of a T-shaped three-way structure, an upper port 803 of the composite joint 8 is provided with a blocking head 9, a lower port 801 is connected with the bronchial catheter 2, and a side port 802 is externally connected with a sputum aspirator; 2 middle parts of bronchus pipe are provided with the buckle of silica gel material, the buckle comprises buckle one 3 and buckle two 5, buckle one 3 and buckle two 5 all are U type structure, the symmetry is provided with the arch on the inner wall of every buckle, buckle one 3 the card is on bronchus pipe 2, buckle two 5 the card is on trachea cannula, connect through connecting piece 4 between buckle one 3 and the buckle two 5, connecting piece 4 is rectangular shape structure, the both ends of connecting piece 4 set up respectively to globular joint 401, every globular joint 401 passes the connecting hole of a buckle tail end respectively, because the buckle is the silica gel material, the globular joint 401 of connecting piece 4 can inject the connecting hole, and prevent that connecting piece 4 from droing from the buckle.
