Problems solved by technology

In addition, there is Torres’ protective alveolar lavage with a distal plugged double catheter (TPC). However, due to the difficulty in making PSB, PBTC and TPC, the cost is high, and due to the large diameter of the tube, it is only suitable for the diameter of the suction tube. 2.6 mm bronchoscope
At present, the diameter of the bronchoscope suction tube used by many domestic medical units is 2.0 mm, so it is difficult to popularize and apply.
In order to solve this problem, Wang Jiazhai and Lei Zhenzhi of the First Affiliated Hospital of Dalian Medical College in China designed a double-plug protection measure that plugged the end of the single cannula brush and added a protective plug to the suction hole at the far end of the bronchoscope. Good anti-pollution effect has been achieved, but the operation is complicated and the anti-pollution is limited, especially during alveolar lavage, which is easily polluted, and it is easy to bring pathogens from the upper respiratory tract to the lower respiratory tract, resulting in secondary infection after surgery

Embodiment Construction

[0014] As shown in the figure, a bronchoscope anti-pollution device is in the shape of a sleeve, which consists of a tube body 1, an anti-pollution cap 2 and a joint 3, wherein the anti-pollution cap for closing the tube body 1 is located at the far end of the tube body , there is a slender tail sticking on the outer wall of the tube body 1 on the brim of the anti-pollution cap 2; a joint 3 is set on the proximal end of the tube body 1, and the part of the joint 3 inserted into the proximal end of the tube body 1 is elongated Conical shape, the other end of which expands and protrudes into a cylindrical shape, and there is a protruding small piece on the outer wall. This protruding small piece is on the same level as the tail of the anti-pollution cap glued to the outer wall of the tube. It marks the bonding direction of the anti-pollution cap and the tube body, and it is also used by the doctor to operate the bronchoscope with the anti-pollution device. 4 When the operating h...

Abstract

An anti-polluting unit for fibroscope used to sample the pathogenic bacteria of lung infection has a sleeve tube shape, and is composed of tube body, an anti-polluting cap at the far end of tube body and having a slender tail adhered to external surface of tube body, and an jointer at the near end of said tube body. Its advantages are high safety and effect, and simple operation.

Description

technical field [0001] The invention relates to a device for preventing contamination of pathogenic bacteria specimens of lung infection collected by fiberoptic bronchoscope. Background technique [0002] Pulmonary bacterial infection is still one of the main diseases that seriously endanger human health, and its mortality rate has increased in recent years. Definitive diagnosis of pathogenic bacteria is of great significance for rational application of antimicrobial therapy and improvement of prognosis. Bronchoscopy provides a new way to directly collect secretions from the lower respiratory tract, but the front end and suction tube of the bronchoscope are often polluted when passing through the upper respiratory tract, so direct sampling with the bronchoscope cannot be used for bacteriological examination. In order to solve this difficult problem, the medical circle has carried out research and experiments from two aspects of anti-pollution in the suction hole of the bron...
