Description

Technical Field

[0001] The utility model relates to the technical field of equipment sealing structures, in particular to a dual-purpose joint sealing structure. Background Art

[0002] Oxygen inhalation and nebulized drug administration are both commonly used treatment methods in clinical practice. Usually, in order to ensure the humidity of the oxygen inhaled by the patient during oxygen inhalation, the oxygen needs to be humidified through a humidifier bottle before inhalation and then supplied to the patient for oxygen inhalation therapy. Nebulized drug administration is to use high-speed oxygen or air flow in the nebulizer to break up the drug solution into mist. After inhalation into the patient's respiratory tract, it can eliminate local inflammation, edema, relieve spasms and dilute sputum.

[0003] Deficiencies of existing technology:

[0004] At present, in the actual treatment process, some patients need both oxygen inhalation and liquid nebulization treatment. If two different devices are used for operation, they need to be frequently replaced, which not only increases the workload of nurses, but also reduces work efficiency and wastes medical resources. Therefore, a dual-use connector is used for exchange, which can effectively improve the work efficiency of nurses and reduce the time of repetitive work. However, the service life of this dual-use connector is not long. During use, the O-ring sealing structure is easily damaged, resulting in air leakage and reduced work efficiency.

[0007] a reversing valve stem, the reversing valve stem being arranged inside the dual-use joint body;

[0008] An O-ring is provided on both sides of the reversing valve stem along the second direction.

[0009] Preferably, a plurality of U-shaped grooves are provided on both sides of the reversing valve stem, and the O-rings are assembled in the U-shaped grooves.

[0010] Preferably, the material of the O-ring is EPDM.
