Description

Closed sputum suction tube

Technical Field

The utility model relates to the field of medical supplies, in particular to a closed sputum suction tube.

Background

The prior sputum suction tube has the following problems:

when a tracheal intubation patient humidifies an airway, humidifying liquid cannot be effectively pumped into the airway, so that the humidifying airway is insufficient. The designed humidifying liquid inlet is in an open state when being operated, so that the protection on workers and patients is insufficient, and the infection risk is high; when the sputum specimen is retained and taken, the whole closed sputum aspirator needs to be pulled out, so that the pain of a patient is easily caused, and the pollution of sputum to the environment is increased; the port connected with the connecting respirator is easy to cause the backflow of the humidification liquid, and the humidification liquid of the air passage and the sputum with bacteria of the patient are easy to cause the pollution of the pipeline of the respirator.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a closed sputum suction tube which is convenient to operate and can reduce pollution.

In order to solve the technical problem, the utility model provides a technical scheme as follows:

on the one hand, the utility model provides a phlegm pipe is inhaled to closed, including inhaling phlegm pipe body and connecting at the attraction connection port and the tee bend port of inhaling phlegm pipe body both ends, attract connection port to be used for being connected with the attraction switch, the tee bend port includes breathing machine connection port and trachea cannula port, it is equipped with the tubulose interface in the connection port to attract, the tubulose interface communicates with each other with inhaling phlegm pipe body for grafting phlegm sample sampling tube or grafting humidifying liquid pipe.

Further, the tubular interface is a hard plastic interface.

Furthermore, a circular membrane group consisting of at least two pieces of membrane sheets is arranged in the connecting port of the respirator and is used for preventing the sputum from flowing backwards.

Furthermore, a circular diaphragm group consisting of two semicircular diaphragms is arranged in the connecting port of the respirator.

Further, the closed sputum suction tube is packaged in a disposable sterile mode.

After adopting such design, the utility model discloses following advantage has at least:

the tubular interface added in the utility model can be used as an interface for reserving and taking a sputum sample, a closed sputum aspirator is not required to be disassembled, the tubular interface is directly connected with the sputum aspirator, and the device is sterile, convenient and quick, can be repeatedly used for multiple times to reserve and take the sputum sample, reduces the environmental pollution and protects medical staff from cross infection; and because the design of tubulose interface, pour into humidifying liquid dilution sputum into from the tubulose kneck after inserting the phlegm suction pipe to can omit the humidifying liquid entry design of tee bend port department, the utility model discloses the port position of improvement humidifying air flue has effectively promoted the intensity of humidifying air flue, has prevented the refluence of humidifying liquid, takes the fungus humidifying liquid and takes the fungus sputum splash when having avoided using, also reduces medical staff infection risk simultaneously. The added thin film piece of the connecting port of the respirator pipeline prevents the splash of the sputum with bacteria and the pollution of the humidifying liquid backflow to the respirator pipeline.

Drawings

The foregoing is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clear, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
