Sputum culture and suction device

Abstract

The invention discloses a sputum culture and suction device. The sputum culture and suction device comprises a culture dish, a sputum suction tube, an eduction tube and a culture dish cover which is located above the culture dish. The sputum suction tube and the eduction tube are inserted in the culture dish cover which comprises a rotatable round switch block and a selector channel which is formed in the round switch block. The round switch block further comprises a knob arranged on the outer side of the culture dish cover. The selector channel transversely penetrates through a fixing block. The two ends of the selector channel can be communicated with the sputum suction tube and the eduction tube. Sputum can be selectively preserved by controlling the round switch block.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a sputum suction device. Background technique [0002] In clinical work, it is often necessary to take sputum samples from patients for examination in order to provide a basis for clinical treatment. Generally, patients can cough up sputum and leave it in a sterile petri dish for examination, but it is difficult for patients with endotracheal intubation to cough up sputum from the endotracheal tube, so a sputum aspirator is generally used to collect specimens. [0003] At present, the commonly used clinical method is to use a disposable sputum culture special suction tube to connect a negative pressure suction device when the patient’s sputum is blocked and needs to suck sputum. Submit for inspection. [0004] This method solves the shortcomings of the traditional method that the sputum may be contaminated and is not easy to operate, but it also has the following di...

AI Technical Summary

Problems solved by technology

[0004] This method solves the shortcomings of the traditional method that the sputum may be contaminated and is not easy to operate, but it also has the following disadvantages: clinically, the patient has a lot of sputum, and the use of the sputum culture suction tube cannot continue after the amount of sputum sucked reaches the test volume. Aspirate the sputum in the patient's trachea to clear the airway and relieve the patient's dyspnea. At this time, another sputum suction tube must be changed to continue to suck sputum.

This not only wastes time and resources, but also increases the hidden danger of violating the principle of sterility

Often some operators do not pay attention to the aseptic principle when suctioning sputum for the second time because of gaining time, such as not changing disposable gloves and suction water, etc.

In addition, the traditional sputum culture suction tube can not control the selection of the location and properties of the sputum. If you want to keep the sputum from the deep part of the trachea, you want to avoid the sputum mixed with sputum, blood, and saliva. Or find abnormal sputum during sputum suction, etc.
