In other embodiments, the four support wings may be the same size.
In this embodiment, the included angle between two adjacent support wings 16 is an obtuse angle, so that the cross-sectional dimension of the drainage groove is large, and the drainage groove is favorable for flowing out pus. In this embodiment, the front end of the support wing 16 is arc-shaped, which is beneficial to inserting the drainage tube into the pus cavity and avoiding the bleeding caused by puncturing the blood vessel of the wound surface.
It should be noted that the drainage tube is made of a soft material, such as rubber, so as to avoid damage to the wound abscess.
At the drainage postoperative, the initial stage of pustule healing, the pustule is bulky, and the pus is also more, with the whole pus intracavity of inserting of drainage tube, the pus is flowed out by drainage groove 14, if need wash, then connect the syringe with the connector 17 of drainage tube, push the flush fluid in to centre bore 18 through the syringe to wash the pus in the pus intracavity, final pus and flush fluid flow out from drainage groove 14 together. In pustule healing later stage, the pustule cavity is less, and the pus is also less, can extract the back support section 15 of drainage tube, and only support section 12 is in the pustule intracavity before remaining for preceding support section 12 matches the volume in pustule, need not to change the drainage tube like this, just can continue the drainage, and is comparatively convenient. Wherein the rear support section 15 may be cut away in order to avoid affecting the patient's movement.
