Description

A new type of suction tube

technical field

The utility model relates to a medical appliance, in particular to a novel sputum suction tube which can be used for collecting sputum samples for inspection.

Background technique

In clinical nursing work, accurate and effective collection of sputum samples for inspection, bacterial culture and drug sensitivity test is the key to the rational use of antibiotics for patients with respiratory system infections. For patients who are unable to expel sputum on their own while using ventilator-assisted breathing, how to correctly collect sputum samples through the suction tube and suction device is a key issue.

At present, the sputum suction tube used clinically generally adopts a flexible pipe, one end of the flexible pipe is a sputum suction end, and the other end of the flexible pipe is a connecting end. When in use, the connecting end of the hose is connected with the aspirator, and then the sputum suction end of the hose is inserted into the patient's respiratory tract, and the sputum is sucked out by the negative pressure of the aspirator.

In the process of suctioning sputum for patients, it is often necessary to take samples for testing. When collecting sputum samples through the existing sputum suction tube for inspection, the operation process is cumbersome, and the sputum samples retained are not easy to collect; at the same time, the retained sputum samples Sputum samples are easily contaminated, which leads to deviations in laboratory results, so it cannot accurately and objectively characterize the disease, and cannot provide a scientific basis for clinical practice.

Contents of the invention

The technical problem to be solved by the utility model is to provide a new type of sputum suction tube, which is convenient to use and easy to operate. It improves the accuracy of the test results, improves the qualitative diagnosis rate of the disease, and provides a scientific basis for clinical practice.

In order to solve the problems of the technologies described above, the technical scheme adopted by the utility model is as follows:

A new type of sputum suction tube, including a flexible tube, one end of the flexible tube is a sputum suction end, and the other end of the flexible tube is a connecting end. Aspirator connecting pipe, one end of the above-mentioned intermediate connecting pipe is detachably sealed with the connecting end of the hose, and the other end of the intermediate connecting pipe is fixedly arranged on the sputum storage cavity and communicated with the sputum storage cavity; the above-mentioned suction device The connecting pipe is fixedly arranged on the sputum storage chamber, one end of the aspirator connecting pipe is located in the sputum storage chamber and communicates with the sputum storage chamber, and the other end of the aspirator connecting pipe is the aspirator connecting end.

When in use, connect one end of the intermediate connecting tube to the connecting end of the flexible tube in a sealed manner, connect the connecting end of the suction device connecting tube to the suction device, then insert the suction end of the flexible tube into the patient's respiratory tract, and pass through the suction device The negative pressure effect of the patient's sputum flows into and is stored in the sputum storage cavity after passing through the hose and the intermediate connecting tube. Then, the operator gently folds back the middle part of the suction device connecting tube to prevent the sputum from being sucked and sucked. At the same time, close the suction device; then, separate the flexible tube from the intermediate connecting tube, and according to the principle of aseptic operation, put the sputum in the sputum storage chamber into the culture bottle for inspection by gravity.

The sputum storage cavity is preferably made of transparent material. In this way, when sucking sputum, the operator can conveniently observe the inflow of sputum samples in the transparent sputum storage cavity, and make the sputum storage cavity be filled with enough sputum samples.

As a preferred structure of the present utility model, the sputum storage chamber adopts a Muffer's dropper. The above-mentioned Murphy's dropper is prior art, and this part is a part on a commonly used disposable infusion set.

As a further improvement of the utility model, a switch valve is provided on the connecting pipe of the suction device. Through the control of the switch valve, it is convenient to make the connecting pipe of the suction device in a conduction state or in a non-conduction state.

Said hose preferably consists of a transparent silicone material. Because the transparent silica gel material has certain elasticity, it is convenient to connect, so, adopting the hose made of transparent silica gel material can make the connection of the new type of sputum suction tube more convenient, and can be properly adjusted during connection, so that the new type The operation of the suction tube becomes simpler and more convenient.

The suction end of the hose is preferably provided with an opening and a side hole. Through the opening and the side hole, the sputum can be sucked more conveniently.

The beneficial effects of the utility model compared with the prior art are:

Since the new type of sputum suction tube adds a sputum storage cavity on the basis of the existing sputum suction tube, the sputum sucked during operation will automatically gather in this storage cavity to keep an appropriate amount of sputum. When the specimen is collected, it can be taken out from the sputum storage cavity and sent for testing. Therefore, the new sputum suction tube is convenient to use, easy to operate, and saves time and effort;

At the same time, the new sputum suction tube can effectively avoid contamination of the collected sputum specimens during sputum suction, and realize aseptic operation. Moreover, the new sputum suction tube is a disposable product, which is directly used for taking sputum samples. Reduce the pollution caused by mechanical expectoration and affect the test results, thereby ensuring the accuracy of test results, improving the qualitative diagnosis rate of diseases, and providing scientific basis for clinical practice.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
