Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a single-lung ventilation isolation valve. Background Art

[0002] Single-lung ventilation refers to a method of ventilation in which patients undergoing thoracic surgery use only one lung (the non-surgical side) via a bronchial tube. When a double-lumen bronchial tube is used for lung isolation (single-lung ventilation) during clinical thoracic surgical anesthesia, the usual operation is to use an isolation forceps to clamp the plastic hose on one side of the double-lumen bronchial tube connection set, so that the ventilator gas only enters the non-clamped airway and not the clamped airway, so as to achieve the purpose of single-lung ventilation.

[0003] The respiratory tract of the clamped lung can be opened to facilitate the release of residual air and suction of secretions in the clamped lung, while the contralateral non-clamped lung remains ventilated to maintain the patient's oxygen supply. The disadvantage of this method is that the isolation forceps are bulky and inconvenient to operate, and the operation of suctioning lung secretions requires separate equipment, which increases the operation steps and is not conducive to improving surgical efficiency.

[0004] Therefore, there is a need for a single-lung ventilation isolation valve that is easy to operate, can suction the patient's lung secretions, and improve work efficiency. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a single-lung ventilation isolation valve, which can effectively absorb the patient's lung secretions and at the same time achieve the purpose of single-lung ventilation and regulating ventilation volume, thereby improving work efficiency.

[0006] In order to achieve the above purpose, the utility model proposes the following specific solutions:

[0007] The closure of the valve body is connected with the closure of the valve body by the spring, and the closure of the valve body is connected with the closure of the valve body by the spring.

[0008] As an optimal technical solution of a single-lung ventilation isolation valve of the utility model, an adjustment component is provided on the edge of the outer wall of the valve body, and the adjustment component includes an air guide tube, a connecting tube, a hollow adjustment plate, a sealing plate and an adjusting screw. The air guide tube is fixedly connected to the edge of the outer wall of the valve body, a hollow adjustment plate is fixedly provided at one end of the air guide tube, a rotating hole is provided in the middle of the top surface of the inner wall of the hollow adjustment plate, a sealing plate is movably provided in the hollow adjustment plate, a second thread groove is provided in the middle of the top surface of the sealing plate, an adjusting screw is threadedly connected on the inner side of the second thread groove, one end of the adjusting screw is movably inserted in the rotating hole, a limiting ring is sleeved on the outer wall of one end of the adjusting screw, the limiting ring is located on one side of the rotating hole, and a connecting tube is fixedly provided on the side end surface edge of the hollow adjustment plate.

[0009] As an optimal technical solution for a single-lung ventilation isolation valve of the utility model, a vent pipe is provided in the middle of the outer wall of the valve body, the vent pipe is located on one side of the adjustment component, a sealing plug is clamped at one end of the vent pipe, a connecting belt is provided at the edge of the outer wall of the vent pipe, and one end of the connecting belt is connected to the outer wall of the sealing plug.

[0010] As a preferred technical solution of a single-lung ventilation isolation valve of the utility model, a sealing ring is sleeved on the outer wall of one end of the valve body, and the valve cover is clamped on the outer side of the sealing ring.

[0011] As a preferred technical solution of a single-lung ventilation isolation valve of the utility model, the airway tube, the connecting tube and the internal space of the hollow adjustment plate are interconnected.

[0012] As a preferred technical solution of a single-lung ventilation isolation valve of the utility model, the size of the sealing plug is adapted to the size of the deflation tube, and the sealing plug is made of a flexible material.

[0013] As a preferred technical solution of a single-lung ventilation isolation valve of the utility model, the pull-out tube is made of a flexible material, and the pull-out rod is made of a flexible material.

[0014] As a preferred technical solution of a single-lung ventilation isolation valve of the utility model, a plurality of liquid guide holes are provided.

[0015] Compared with the existing technology, the utility model has the following beneficial effects:

[0016] The utility model uses a liquid collecting component to absorb secretions such as mucus in the patient's lungs, inserts an elastic catheter into the patient's bronchus to connect it with the lungs, and pushes the pull-out rod to drive the liquid collecting cylinder to move to the patient's lungs. Since the pull-out rod and the pull-out tube are made of flexible materials, they can be bent and adapted according to the curvature of the pipeline. The multiple liquid guide holes at the bottom of the liquid collecting cylinder can easily allow mucus to pass through and be adsorbed on the moisture-absorbing pad. If the patient has too much mucus in the lungs, the pull-out tube can be pinched with one hand, and then the end of the pull-out rod can be pulled with the other hand to drive the moisture-absorbing pad to move inside the liquid collecting cylinder. Since mucus fills the liquid guide holes, negative pressure is generated at one end of the liquid collecting cylinder as the moisture-absorbing pad moves, thereby extracting the patient's lung mucus. The liquid collecting cylinder and the threaded cover are threadedly connected, and the pull-out rod and the moisture-absorbing pad are also threadedly connected, which is convenient for subsequent cleaning and replacement of the moisture-absorbing pad, thereby improving the work efficiency of medical staff.

[0017] The utility model controls the patient's single-lung ventilation through the arranged adjustment component, and a hollow adjustment plate is provided between the airway tube and the connecting tube. By connecting the connecting tube to the double-lumen bronchial catheter and twisting the adjustment screw in the hollow adjustment plate, the blocking plate is driven to move, so as to block the airflow between the airway tube and the connecting tube, and also to adjust the airflow passing amount between the airway tube and the connecting tube, thereby blocking or adjusting the ventilation volume of the patient's single lung. By connecting two devices to the two lungs of the patient respectively, the ventilation volume of the two lungs of the patient can be adjusted at the same time. Compared with the traditional use of clamps for ventilation blocking, the present solution has a high degree of adjustability, is simpler and more convenient to operate, and is conducive to improving efficiency.

[0018] The utility model discharges the patient's lung gas through the provided venting tube. By pulling out the sealing plug, the patient's lung gas can be discharged from the body through the valve body and the venting tube, which is convenient for subsequent use of the liquid collecting component to attract the patient's lung mucus and also convenient for the doctor to perform subsequent surgery.
