Description

Multifunctional drainage tube and positioning assembly thereof Technical Field The utility model relates to the technical field of medical instruments, in particular to a multifunctional drainage tube and a positioning assembly thereof. Background The drainage tube is used as a medical instrument and is mainly used for clinical surgery drainage and is used for guiding pus, blood and liquid accumulated in human tissues or cavities to the outside of the body so as to prevent postoperative infection and promote wound healing. In the use, because the drainage tube has certain length, easily take place offset not hard up scheduling problem, in order to prevent that the drainage tube from taking place to remove and rocking, need carry out fixed processing to it, under the partial circumstances, when needs keep somewhere the drainage tube in the patient, in order to avoid the drainage tube to deviate from the affected part, more need carry out firm fixation to it. At present, the drainage tube is fixed clinically, namely, the drainage tube is fixed from the outside of the drainage tube in a manner of using friction force, a common method is to fix the drainage tube on the skin by using a medical adhesive tape so as to prevent the displacement of a tube body, the adhesive tape is fixed insufficiently and easily to fall off due to the relative smoothness of the surface of the existing drainage tube, the adhesive tape is required to be replaced regularly, the problem that the sensitive part or the guiding-out part of the adhesive tape is inconvenient to be attached to part of patients also exists, the outer wall of the drainage tube is surrounded and fastened by a medical bandage or gauze, and the surface of the drainage tube is relatively smooth, so that the positioning effect of fixing by using the friction force is not ideal, and the situation that the drainage tube falls off easily occurs. The other mode is to clamp the drainage tube, and the drainage tube is fixed through a special fixing device, such as clamping or binding fixing by using a drainage tube fixing clamp or a special fixing belt and other devices, so that the drainage tube can be fixed more firmly, the risk of tube body displacement and falling is reduced, but the drainage tube is easy to squeeze and deform, so that blockage occurs, the drainage effect is poor, the structure of the special fixing device is relatively complex, the occupied space is large, the practical use is inconvenient, and the use is more inconvenient especially when the reserved position of the joint of the drainage tube and the skin is relatively small. In addition, the price of the special fixing device is relatively high, and thus the economic burden of the patient is increased. ‌ Is also a mode of fixing through stitching, generally after the drainage tube is stably placed, 1 to 2 needles are stitched at the joint of the drainage tube and the skin, the caliber of the joint of the skin is tightened, and then the suture is knotted on the drainage tube to fix the drainage tube, but the stitching is the most firm, the operation process is relatively complex, the positioning accuracy and the firmness mainly depend on the clinical experience of operators, the requirements are higher, the infection risk exists, strict aseptic operation is needed, and the problem that needs to be considered when the drainage tube is used is avoided how to avoid infection. Therefore, there is an urgent need for a multifunctional drainage tube and a positioning assembly thereof that has a simple structure, is convenient to fix, has good drainage and fixing effects, and effectively reduces infection risk to solve the above problems. Disclosure of utility model The utility model aims to provide the multifunctional drainage tube which has the advantages of simple structure, convenience in fixation, good drainage and fixation effects and effectively reduces the infection risk. Another object of the present utility model is to provide a positioning assembly for fixing the above-mentioned multifunctional drainage tube. In order to achieve the above purpose, the utility model discloses a multifunctional drainage tube, which comprises a tube body and penetrating grooves arranged on the tube body, wherein the penetrating grooves are arranged along the radial direction or the axial direction of the tube body and are positioned between the inner wall and the outer wall of the tube body, penetrating holes and penetrating holes are formed in the outer wall of the tube body, the number of the penetrating grooves is one or more, and the penetrating grooves are distributed at intervals along the axial direction of the tube body. Compared with the prior art, the multifunctional drainage tube comprises the tube body and the penetrating groove arranged on the tube body, and the penetrating groove is arranged between the inner wall and the outer wall of the tube body, and the penetrating hole are formed in the outer wal
