DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the device of the present invention more clear, the technical solution in the embodiment of the device of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the device of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiment of the device of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the device of the present invention.

[0018] likeFigures 1 to 5 As shown in the figure, a disposable sterile multi-serous cavity effusion drainage device provided by the present invention is an improvement on the original drainage facility. The purpose of the improvement is to make clinical work easier, improve efficiency, reduce waste of unnecessary medical materials, and reduce costs. The improved disposable sterile multi-serous cavity effusion drainage device can be made into a drainage package, which includes the following configurations in the operation sequence: drainage package wrapper, disposable sterile gloves, disposable forceps, dry cotton balls and disinfectant, disposable non-woven fabric hole, disposable 5-ml syringe, small gauze piece, disposable blade, skin dilator 1, graduated inner tube 7, flexible drainage tube 9, upper stop clamp 13, lower stop clamp 14, drainage catheter fixation patch, disposable syringe, disposable effusion bag 12. The requirements for the manufacturing process of the skin dilator 1 are as follows: plastic material can be selected for injection molding, 3-5 disconnection seams 4 can be selected and evenly distributed on the peripheral wall of the conical tip 3. The disconnection seams 4 must disconnect the wall of the conical tip 3, and no burr adhesion is allowed. The width of the disconnection seams 4 should be minimized. It is necessary to make the conical tip 3 smoothly screw into the patient's serous cavity and make the inner tube 7 smoothly expand the conical tip 3 to implement drainage. Axial slot holes 6 are provided on the peripheral surface of the lower end of the inner tube 7, and their function is to increase the drainage fluid discharge flow rate. Especially when encountering viscous drainage fluid, it can also prevent the drainage fluid from being blocked. If blockage occurs, it will not only increase medical expenses, take time and energy, but also require re-puncture to increase the patient's pain.

[0019] The operation steps of the present invention: (see Figure 3 , Figure 4 ) One, the doctor clamps the upper stop clamp 13 on the upper part of the inner tube 7, and the lower end of the inner tube 7 is located inside the skin dilator 1. After selecting the puncture site of the patient and injecting anesthetic for sufficient anesthesia, the conical tip 3 is slowly rotated and aligned with the puncture point and inserted into the patient's drainage site. Two, the doctor holds the skin dilator 1 firmly with one hand to keep it in position, and slowly presses down the inner tube 7 with the other hand to expand the lower port to open the disconnection seams 4 on the peripheral wall of the conical tip 3. Three, (see Figure 5 ) Rotate the skin dilator 1 in the reverse direction to move it upward along the inner tube 7 and away from the patient's body, and clamp the lower stop clamp 14 on the inner tube 7 below the skin dilator 1. Four, remove the upper stop clamp 13. To avoid the outflow of the liquid in the inner tube 7, the internal liquid can be drawn out with a disposable syringe. The skin dilator 1 can be sleeved on the inner tube 7 or withdrawn. Five, connect the inlet 8 of the flexible drainage tube 9 to the upper end of the inner tube 7, insert the outlet 11 of the flexible drainage tube 9 into the effusion bag 12, and remove the lower stop clamp 14 to allow the effusion in the patient's serous cavity to enter the effusion bag 12 through the inner tube 7 and the drainage tube 9.

[0020] In addition, the device can also take the following measures: First, increase the inner diameters of the skin dilator 1 and the inner tube 7. Second, configure a suitable liquid accumulation tank or liquid accumulation bottle. Third, at the beginning of the operation, use a blade to make a small incision in the patient's drainage skin to facilitate the rotation of the skin dilator 1. The above measures can enable the present invention to be used for the drainage of gas and gas-liquid mixtures and for the treatment of pneumothorax and hydropneumothorax.

[0021] According to the disclosure and teaching of the above specification, those skilled in the art to which the device of the present invention pertains can also make appropriate changes and modifications to the above embodiments. Therefore, the device of the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the device of the present invention should also fall within the protection scope of the claims of the device of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the device of the present invention.
