Description

Two-way valve with multi-azimuth rotation function

Technical Field

The utility model belongs to the technical field of medical auxiliary components, and particularly relates to a two-way valve with a multi-directional rotation function.

Background

The ultrasonic bronchoscope guided transbronchial needle biopsy (EBUS-TBNA) is a commonly used diagnosis means for the enlargement diseases of the pulmonary portal and mediastinal lymph nodes at present, and particularly becomes the most commonly used diagnosis technology beyond the common bronchoscope examination in the clinical work of respiratory department and thoracic surgery of various hospitals.

The basic principle of the technology is that an ultrasonic probe at the tail end of a bronchoscope is used for detecting the swollen tissues outside the bronchus or the lung portal of a trachea, so that accurate transmural needle aspiration and puncture are performed in a bronchial cavity to obtain high-quality tissues for definite disease diagnosis.

In operation, there is a very important step that the probe device at the end of the bronchoscope is covered with a water bag, and the water bag is filled by injecting sterile water from the perfusion opening of the bronchoscope operation handle part, so as to be tightly attached to the airway wall for improving the definition of the ultrasonic image. In short, the water-filled balloon acts as a "coupling agent" between the ultrasound probe and the airway wall.

At present, two common water filling operations are adopted, one is that a 10ml syringe is connected with a bronchoscope perfusion opening through an extension tube, and after water injection is finished, a pipeline is clamped and closed through a clamp on the extension tube, so that water in a balloon is prevented from reversely flowing back into the syringe, and the filling degree of the water balloon is ensured. The second is that the injector is directly connected with the perfusion opening through the two-way valve, and the water can not flow back by rotating the knob of the two-way valve after the water injection. The inconvenience of the above operation is that the operator and the assistant are required to complete the operation together, the water bag can be inflated to a proper degree through tacit cooperation, and the assistant needs to quickly clamp the extension pipe or rotate the knob of the two-way valve to prevent the water bag from retracting due to reverse flow. The disadvantage of the two-person cooperation operation is that the risk of instrument contamination is increased, and the assistant is generally responsible for processing the puncture specimen during the operation, so that gloves are not replaced, and 2-3 times of repeated puncture operations are needed for each part of the operation, and the assistant has the risk of instrument contamination due to the fact that the assistant touches different areas for multiple times.

Although the second method can be independently completed by an operator, the second method is very inconvenient, the operator needs to stare at the screen during operation, the water injection action of the injector is usually 'blind operation', and the operator needs to move a hand from the injector to the position of the two-way valve after the water injection is finished, so that the injector is very easy to fall off, the water bag is retracted along with the water bag, and the time cost is increased.
