Description

A sputum collector for artificial airway patients that is convenient for aseptic operation

technical field

The utility model relates to the technical field of medical devices, in particular to a sputum collector for artificial airway patients which is convenient for aseptic operation.

Background technique

Sputum is a secretion produced by the trachea, bronchi, and alveoli, and normally produces very little. The main components of sputum are mucus and inflammatory exudates. If accompanied by respiratory diseases or other system diseases with respiratory symptoms, the volume of sputum will increase, and its transparency and properties will also change. In clinical practice, sputum culture specimens are often taken to examine pathogenic bacteria in sputum to provide a basis for selecting antibiotics. Therefore, the collection of correct sterile sputum culture specimens is to provide the basis for clinical examination, diagnosis and treatment.

The sputum collector is a commonly used medical auxiliary device in clinical practice, and is often used for the collection of sputum specimens from those who are unable to expectorate sputum or who are uncooperative. The existing sputum collector includes: a sputum storage box body, a sputum suction tube, a negative pressure interface, a spare sputum storage box cover, and the sputum storage box cover is provided with a sputum suction tube and a negative pressure interface. When a patient with artificial airway mechanical ventilation needs to collect sputum for culture, it is necessary to connect the negative pressure interface to a negative pressure source to provide negative pressure, wear sterile gloves, and insert the end of the suction tube with a side hole into the patient's artificial airway. The sputum in the trachea is sucked into the sputum storage box through the suction tube. But this structure has the following disadvantages:

1. Two-person operation is required when using, that is, the first operator needs to wear sterile gloves, take out the negative pressure tube, and connect the negative pressure; the assistant is responsible for connecting and disconnecting the ventilator and assisting in fixing the artificial airway. This is cumbersome and increases workload, labor costs and medical costs. 2. Because the suction tube is soft and has no fixed device, such patients are a little restless and uncooperative, and the suction tube is easily contaminated; after the suction is completed, if the patient has less sputum, it is necessary to pour sterile saline or open it for external use. Washing with sterile normal saline is more troublesome and increases medical costs. During the movement of the suction tube, it is easy to increase the risk of contamination, increase the probability of specimen contamination, and increase the positive rate of specimens. Unreasonable specimen collection will affect the accuracy of test results, which may affect the diagnosis and treatment of diseases by clinicians. 3. When discarding the waste, it is often necessary to turn the gloves to wrap the contamination of the suction tube. Improper operation may cause body fluids to splash and increase the occupational exposure risk of medical staff. 4. There is no special sputum collector for patients with artificial airway.
