Description

Technical Field

[0001] This utility model relates to the field of drainage devices, specifically to a protective connector for a subcutaneous drainage tube. Background Technology

[0002] Subcutaneous drainage tubes are widely used for medical purposes such as postoperative drainage and fluid drainage. They are usually connected to a negative pressure suction ball or waste fluid bag through an external drainage tube to achieve the drainage of body fluids.

[0003] However, in existing technologies, the end of the subcutaneous drainage tube is directly exposed on the outer side of the patient's abdomen, making it susceptible to external forces and leading to the following problems:

[0004] Dragging and displacement issues: When moving a patient or when the patient moves, the subcutaneous drainage tube may be pulled by external forces, causing the end of the drainage tube to move or even fall off.

[0005] Loose connections: Due to the uncertainty of the external environment, the connection between the negative pressure suction ball or waste bag and the subcutaneous drainage tube is easily affected, resulting in decreased sealing and air leakage, which in turn affects the effect of negative pressure suction.

[0006] Increased risk of infection: Subcutaneous drainage tubes are exposed to the external environment and lack effective protective measures, making them susceptible to contamination by external germs and dust, increasing the risk of infection for patients.

[0007] Leakage of bodily fluids: When the external drainage tube is disconnected or replaced, failure to take effective sealing measures may lead to leakage of bodily fluids, which may affect the patient's comfort and may also contaminate the surrounding environment. Utility Model Content

[0008] The purpose of this invention is to provide a protective connector for a subcutaneous drainage tube to solve the problem that the end of the subcutaneous drainage tube is directly exposed on the outside of the patient's abdomen and is easily subjected to external forces.

[0009] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0010] A protective connector for a subcutaneous drainage tube includes a bowl, an adhesive portion, a two-way connector, and a protective cap. The adhesive portion is connected to the rim of the bowl and is a flexible sheet with adhesive properties that allow the bowl, when inverted on a patient, to adhere to the patient's skin. The two-way connector extends through the bowl, with its two ends located inside and outside the bowl, respectively, and both ends of the two-way connector are used to connect the drainage tube. One end of the protective cap is connected to the bowl via a hinge, and the other end of the protective cap can be engaged or disengaged from the bowl. When operated, the protective cap can cover or expose the end of the two-way connector located outside the bowl.

[0011] Furthermore, a sealing plug is provided on the side of the protective cover facing the two-way connector. When the protective cover covers the surface of the bowl, the sealing plug is inserted into the interior of the two-way connector to seal the subcutaneous drainage tube and prevent the leakage of bodily fluids.

[0012] Furthermore, the bowl body is provided with a buckle, and the end of the protective cover away from the hinge is provided with a corresponding snap-fit. After the buckle and the snap-fit ​​are engaged, the protective cover covers the end of the two-way connector located outside the bowl body. The buckle and the snap-fit ​​can engage or disengage, so that the protective cover can engage with or not engage with the bowl body.

[0013] Furthermore, the hinge includes a fixed shaft, a swing arm, and a movable shaft. The fixed shaft is fixedly connected to the bowl body, the movable shaft is fixedly connected to the protective cover, and the two ends of the swing arm are respectively connected to the fixed shaft and the movable shaft. The swing arm can rotate around the fixed shaft, so that the movable shaft and the protective cover can swing on the outside of the bowl body through the swing arm.

[0014] Furthermore, a spring contact is provided on one side of the two-way connector located outside the bowl body, connected to the bowl body. The outward-facing end of the spring contact is bent in a direction away from each other to form a smooth curved surface. When no external force is applied, the minimum distance between the spring contact and the two-way connector is less than the wall thickness of the external drainage tube, and the maximum distance between the spring contact and the two-way connector is greater than the wall thickness of the external drainage tube. When the external drainage tube is inserted into the two-way connector located outside the bowl body, the spring contact abuts against the outer wall of the drainage tube to prevent the external drainage tube from separating from the two-way connector when dragged.

[0015] Furthermore, the spring is connected to the bowl body by bolts.

[0016] Furthermore, the bottom of the bowl is provided with a handle, which faces away from the patient when the bowl is inverted on the patient.

[0017] Compared with the prior art, this application has the following advantages:

[0018] A protective connector for a subcutaneous drainage tube is provided. During use, the subcutaneous drainage tube and the external drainage tube are connected through a two-way connector to form a drainage channel from the patient's body to the outside of the body. When not in use, the external drainage tube is removed, and the end of the two-way connector located outside the bowl is covered by a protective cap to prevent external pathogens and dust from entering the subcutaneous drainage tube.
