A separable liquid-collecting type sputum suction device

Abstract

The invention discloses a detachable liquid-collecting type sputum suction device, which comprises a liquid-collecting bottle, a negative-pressure suction tube and a collecting tube. The negative-pressure suction tube is connected with the negative-pressure device and the liquid-collecting bottle. The suction port of the bronchoscope is connected, and the liquid collection bottle includes an upper cover, a lower cover, a collection bottle and a sampling test tube; Semi-closed type, the cavity between the outer bottle and the isolator is sealed at the lower ends of the two, and the unsealed space at the lower end of the outer bottle is used for the passage of the sampling test tube; the sampling test tube is nested in the collection bottle The inside of the isolation body, the lower end of the sampling test tube is sealed, and the outer wall of the lower end of the sampling test tube is attached to the lower end of the outer bottle; Cap the test tube connected to the sampling test tube. The invention integrates common sputum suction and sample collection, and achieves the purpose of collecting sputum samples accurately without pollution.

Description

Technical field: [0001] The invention relates to the field of medical instruments, in particular to a separable liquid-collecting sputum suction device. Background technique: [0002] In the field of clinical medicine, the liquid-collecting sputum suction device is a common device that provides an important basis for the diagnosis of lung diseases. [0003] ICU patients often use artificial airways, mechanical ventilation, etc., and there are many airway secretions. Due to long-term bed rest, combined with disturbance of consciousness, cough and swallowing reflexes are weakened or disappeared, and the patient's ability to expectorate is reduced, which can easily lead to pulmonary infection. When airway ventilation is blocked, the bronchial tubes are blocked, air cannot enter the lungs, and the air in the original alveoli is absorbed again, the lungs are extremely atrophied, and atelectasis is very likely to occur. [0004] Ordinary sputum suction is performed under blind su...

Problems solved by technology

However, when the ordinary suction box is used in conjunction with the bronchoscope, the collection tube needs to be cut by itself, which destroys the sterile state, which not only affects the work efficiency, but also may cause pollution, resulting in inaccurate culture results and affecting the anti-infection treatment of patients.

Moreover, an ordinary suction box is connected between the negative pressure device and the bronchoscope to collect sputum samples. After sampling, the negative pressure device is directly connected to the suction port of the bronchoscope to suck up the upper respiratory secretions. Obviously, this operation It is cumbersome, and the fiberoptic bronchoscope stays in the body for too long, which increases the stimulation of the patient's airway. The ordinary suction box in the prior art cannot meet the needs of use.
