Description

Technical Field

[0001] The utility model belongs to the technical field of drainage tube connectors, and in particular relates to a drainage tube connecting component. Background Art

[0002] Drainage tubes are used for clinical surgical drainage. They are a kind of medical device that guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. When using a drainage tube, it needs to be used in conjunction with a drainage bag. The connection between the existing drainage tube and the drainage bag is achieved by inserting the two ends of the hard connecting tube into the interface of the drainage tube and the drainage bag respectively. During actual use, the connected drainage tube and the drainage bag are easily affected by factors such as the patient turning over, getting out of bed, changing clothes, or negligence, which may pull the drainage tube or the drainage bag, causing the connection between the drainage tube and the drainage bag to loosen or even slip, thereby causing the drainage fluid to overflow, which has an adverse effect on the surrounding environment.

[0003] The Chinese patent document with authorization announcement number CN219071736U discloses a drainage tube fixing device, including a drainage tube support plate, a fixing belt is installed at the left end of the drainage tube support plate, and a support rod is installed on the upper surface of the drainage tube support plate, and two drainage tube fixing plates are installed on the upper end of the support rod, and the left and right sides of the upper drainage tube fixing plate are movably penetrated and connected with fixing bolts, and a fastening component is arranged at the right edge of the upper surface of the drainage tube support plate. The utility model is provided with a fastening component. After the medical staff puts the fixing belt on the outside of the limb part of the drainage patient, the motor is turned on to drive the rotating rod to rotate through the first gear and the second gear to store the fixing belt, so that the device can be firmly fixed on the patient, thereby effectively avoiding the phenomenon of displacement and pulling the drainage tube, and airflow exchange can be carried out on the skin of the area through the ventilation hose to avoid the skin of the area being stuffy and sweating profusely. The two drainage tube fixing plates in the drainage tube fixing device are connected by a fixing bolt, which is inconvenient to disassemble and install. Before drainage, the drainage tube needs to be inserted between the two drainage tube fixing plates to limit the position of the drainage tube. This is very inconvenient in actual use, seriously affecting the patient's usage experience, and is also likely to cause the end of the drainage tube to contact with pathogens, endangering the patient's health. Utility Model Content

[0004] In order to solve the above problems, this patent provides a drainage tube connection assembly.

[0010] Preferably, a clamping belt corresponding to the clamping spring one by one is provided on the fan ring adjustment plate, and the clamping belt is connected to the clamping claw through an adjustment hole arranged on the fan ring clamping plate; the end of the clamping claw away from the adjustment handle is provided with a transverse guide rod, and the transverse guide rod cooperates with the guide grooves arranged on both sides of the clamping groove.

[0011] Preferably, a limiting groove is provided on the top surface of the limiting column, and the limiting groove cooperates with the limiting protrusion arranged on the fan ring adjustment plate; a guide wheel cooperating with the clamping belt is provided in the clamping groove.

[0012] Preferably, an inner-sunk clamping plate is provided at one end of the clamping claw away from the clamping slot, the inner-sunk clamping plate is arranged close to the center side of the fan ring clamping plate, and clamping particles are evenly distributed on the inner side surface of the inner-sunk clamping plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] (1) The utility model can clamp and fix the connection between the drainage tube and the drainage bag through a pair of fan-ring clamping plates connected by a clamping shaft, thereby preventing the connection between the drainage tube and the drainage bag from loosening or slipping due to external force, improving the connection stability and safety between the drainage tube and the drainage bag, and effectively preventing drainage fluid from overflowing. The clamping claws on the side of the fan-ring clamping plate can prevent the drainage tube near the connection between the drainage tube and the drainage bag from bending, twisting and deforming, reducing the interaction force generated by the drainage tube at the hard connecting tube, reducing the probability of the drainage tube and the drainage bag falling off, and improving the connection stability between the drainage tube and the drainage bag.

[0015] (2) The clamping spring exerts a force on the clamping claw, so that the distal end of the clamping claw always keeps the drainage tube vertically connected to the hard connecting tube, thereby reducing the interaction force generated by the drainage tube at the hard connecting tube and reducing the probability of the drainage tube falling off; the adjustment ball facilitates the movement of the clamping claw in the adjustment slot in the clamping slide, facilitates the adjustment of the position of the clamping claw, and facilitates the clamping claw to squeeze or detach from the drainage tube, thereby facilitating the fixation or removal of the drainage tube; the fan ring adjustment plate is rotated on the adjustment column along the adjustment axis through the adjustment handle, and the clamping spring in the clamping slide is adjusted through the clamping belt and adjustment hole on the fan ring adjustment plate, driving the clamping claw to move along the adjustment slot, facilitating the clamping claw to detach from the drainage tube. When the clamping claw close to the limit column moves to the end of the clamping slide, continue to press the adjustment handle, and the clamping claw drives the fan ring clamping plate to rotate along the clamping axis. A pair of clamping axes along the fan ring clamping plate are opened, which is convenient for removing the drainage tube connection component and realizing the rapid disassembly of the component.

[0016] (3) The limiting column limits the position of the fan ring clamping plate so that the fan ring clamping plate is in a suitable position during the clamping process, which is convenient for the assembly to clamp and fix the connection between the drainage tube and the drainage bag; the adjustment handle is rotatably connected to the fan ring adjustment plate through the handle shaft, so that the adjustment handle can be folded on the fan ring adjustment plate when not in use, reducing the impact on the patient during the clamping process. The limiting plate can limit the adjustment handle to a specified position, which is convenient for opening the drainage tube connection assembly through the adjustment handle; the setting of the inner-sunk clamping plate can further increase the fit between the clamping claw and the drainage tube, and cooperate with the clamping particles to further clamp and fix the drainage tube, effectively preventing the drainage tube from bending, twisting and deforming near the connection.
