Description

Closed sputum aspirator tube of tracheotomy

Technical Field

The utility model relates to the field of medical appliances, in particular to a tracheotomy closed sputum aspirator.

Background

At present, a closed type sputum suction pipe on the market, such as CN216394890U, comprises a sputum suction pipe (1), solid-state return bend (2) have been cup jointed to the external fixation of sputum suction pipe (1), sputum suction sleeve (3) have been cup jointed to the fixed one end of sputum suction pipe (1), sputum suction hole (4) have been seted up to the inside of sputum suction sleeve (3), the outside of sputum suction sleeve (3) is provided with clearance mechanism (5), the top of sputum suction pipe (1) is provided with negative pressure pipe (6), top cap stopper (7) have been cup jointed in the activity of the top of negative pressure pipe (6), connecting pipe (8) have been cup jointed to the other end of sputum suction pipe (1).

When the autogenous cutting patient needs fibre bronchoscopy, need to be with inhaling phlegm pipe and patient end and break the connection, connect the feasible fibre bronchoscope in right-angle joint rear, thereby this kind of way increases patient's sputum and splashes thereby medical personnel takes place the possibility that occupational exposure, has also increased the consumptive material to a certain extent and has used, patient's medical cost.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model aims to provide a sputum suction tube for reducing the splashing of sputum of a patient when the tracheostomy patient performs a fiber bronchoscopy.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a trachea opens closed sputum aspirator, is provided with three way connection, connects tracheal connecting pipe, sputum aspirator pipeline and breathing machine pipeline on three way connection way, be provided with the inspection opening on tracheal connecting pipe's the lateral wall or on three way connection, the inspection opening matches with the fibre bronchoscope, can let the fibre bronchoscope pass through and follow tracheal connecting pipe gets into the respiratory track.

As a development, the examination opening is provided with a one-way valve which allows the passage of the fiberbronchoscope and prevents the flow of gas from the interior of the sputum aspirator tube from the examination opening to the exterior of the sputum aspirator tube.

As an improvement scheme, the check valve comprises an elastic sheet, wherein the elastic sheet is provided with a notch formed by a plurality of cutting lines which are intersected at the same point, preferably, the notch is in a shape of a Chinese character 'mi', and when the fiber bronchoscope enters the inspection opening through the check valve, the triangular elastic sheets on the notch in the shape of the Chinese character 'mi' are attached to the fiber bronchoscope, so that gas is prevented from flowing from the interior of the sputum suction tube to the exterior of the sputum suction tube from the inspection opening.

As a further development, the diameter of the examination opening is no more than 150% of the diameter of the fiberoptic bronchoscope.

As a further development, the diameter of the examination opening is no more than 70% of the diameter of the tracheal tube. This prevents obstruction of respiratory airflow during bronchofiberscope examination.

As a further development, the inspection opening is provided with a closing cap on the outside.

As an improvement scheme, be equipped with connector and extension pipe on the breathing machine pipeline.

As an improvement scheme, be equipped with injection unit and water injection unit on the sputum suction pipeline.

As an improvement scheme, a control valve matched with the negative pressure aspirator is arranged on the sputum suction pipeline.

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

an inspection opening is formed in the side wall of the tracheal connecting pipe or the three-way joint, the inspection opening is matched with the fiber bronchoscope, and the fiber bronchoscope can pass through and enter the respiratory tract along the tracheal connecting pipe. The right-angle connector is not required to be connected, consumable use is reduced, only the side opening is opened, sputum splashing is reduced, and occupational exposure possibility of medical staff is reduced.

The inspection opening is provided with the check valve which allows the fiber bronchoscope to pass through and prevents gas from flowing from the inspection opening to the outside of the sputum suction tube in the sputum suction tube, so that the structure is simple and reliable, and sputum leakage can be effectively prevented.

Detailed Description

The utility model will now be further described with reference to the accompanying drawings and examples:

embodiment case one:

as shown in fig. 1 and 2, a tracheotomy closed sputum aspirator tube is provided with a three-way joint 4, a tracheal connecting tube 1 connected on the way of the three-way joint 4, a sputum aspirator tube 2 and a breathing machine tube 3, wherein an inspection opening 5 is arranged on the side wall of the tracheal connecting tube 1 or on the three-way joint 4, the inspection opening 5 is matched with a fiber bronchoscope 6, and the fiber bronchoscope 6 can enter the respiratory tract through and along the tracheal connecting tube 1.

The examination opening 5 is provided with a one-way valve 7 allowing the passage of a fiberbronchoscope 6 and preventing gas from flowing from inside the sputum aspirator tube from the examination opening 5 to outside the sputum aspirator tube.
