Description

Hip joint flushing and drainage assembly

Technical Field

The utility model relates to the technical field of medical devices, in particular to a hip joint flushing and drainage component.

Background technique

Drainage tubes are medical devices that guide pus, blood, and fluids accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some for urinary catheterization, some for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc.

For children, the hip joint is the main site of suppurative arthritis. Compared with other joints, the harm and consequences it brings are more serious, including femoral head necrosis, growth deformity, and unequal length of lower limbs. Early and active surgical treatment is the key to improving prognosis and reducing the incidence of sequelae. However, suppurative hip arthritis in children is often accompanied by infection, such as osteomyelitis, subperiosteal abscess, soft tissue abscess, etc., which requires debridement and drainage to avoid residual infection after surgery.

At present, hip joint debridement and drainage is performed by placing one end of a flushing hose in the joint cavity and the other end connected to an infusion bottle. The infusion bottle is higher than the patient's affected part to continuously flush the patient's joint cavity. At the same time, one end of the drainage hose is also placed in the joint cavity and the other end is connected to the drainage bottle. The drainage bottle is lower than the patient's affected limb for continuous drainage to form a flushing and drainage path. The above-mentioned flushing hose and drainage hose are both long and thin pipes with single-hole flushing and single-hole drainage, which have the following problems:

(1) In case of small blood clots or thick pus, a single flushing hole and a single drainage hole are prone to blockage, resulting in poor flushing or drainage.

(2) If the patient's body position changes or the affected limb moves, the drainage tube may move in the joint cavity, causing poor drainage.

Utility Model Content
