Description

Technical Field

[0001] The present invention relates to the technical field related to medical devices, and in particular to a disposable thoracentesis and drainage kit. Background Art

[0002] Pleural effusion, pneumothorax, traumatic hemothorax, etc. are relatively common in emergency treatment. Some patients require emergency closed chest drainage to relieve their symptoms.

[0003] Traditional closed chest drainage requires medical staff to prepare multiple instruments, and the operation steps are cumbersome. There is a risk of damaging intercostal arteries and veins, nerves, etc., and increasing the risk of infection. It is difficult for doctors with insufficient operation experience to operate. When fixing the drainage tube, it is sutured with needle and thread, and when removing the tube, a suture removal tool is required. Fixing and removal are inconvenient and increase the pain of the patient. The traditional drainage tube is not firmly connected to the drainage bottle, which is easy to fall off, especially during the patient's transportation process. When replacing the drainage bottle, air or external pollutants can easily enter the chest cavity along the drainage tube, causing contamination. Summary of the invention

[0009] Furthermore, a plurality of limiting notches are provided at one end of the connecting sleeve corresponding to the position of the locking rod, and the locking rod is located in the limiting notches. The outward extension angle of the locking rod is limited by the limiting notches, and the limiting notches are driven to rotate by rotating the connecting sleeve to adjust the maximum outward rotation angle of the locking rod.

[0010] Furthermore, one end of the limiting gap gradually narrows toward the other end, and by rotating the connecting sleeve, the limiting gap is driven to rotate along its gradually widening end. When the limiting gap rotates to the narrowest end, the maximum outward extension angle of the locking rod is ≤0°.

[0011] Furthermore, the rotation direction of the locking sleeve toward the connecting pipe after rotation is consistent with the rotation direction of the limiting notch along the gradually widening end thereof.
