Detailed ways

In order to make the purposes, technical solutions and advantages of the device implementation of the present invention clearer, the technical solutions in the device embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the device embodiments of the present invention. Obviously, the described The embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the device of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the device of the present invention.

As shown in Figures 1 to 5, the present invention provides a one-time sterile multi-serous cavity effusion drainage device, which is an improvement on the original drainage facility. The purpose of the improvement is to make clinical work more comfortable and improve efficiency. Reduce unnecessary waste of medical materials and reduce costs. The improved disposable sterile polyserosal effusion drainage device can be made into a drainage bag, which includes the following configurations according to the operation sequence: drainage foreskin, disposable sterile gloves, disposable tweezers, dry cotton balls and sterilization Liquid, disposable non-woven fabric hole, disposable 5ml syringe, small gauze block, disposable blade, skin expander 1, built-in tube with scale 7, flexible drainage tube 9, upper stop clip 13, lower stop clip 14. Drainage catheter fixing stickers, disposable syringes, and disposable effusion bags 12. The requirements for the manufacturing process of the skin expander 1 are: plastic injection molding can be selected, and 3-5 lines can be selected for the breaking seam 4, which are evenly distributed on the peripheral wall of the cone tip 3, and the wall of the cone tip 3 must be broken by the breaking seam 4. Open, no burr adhesion is allowed, and the width of the breaking seam 4 should be minimized. Not only the conical tip 3 can be smoothly screwed into the serous cavity of the patient, but also the built-in tube 7 should be able to open the conical tip 3 smoothly to implement drainage. The peripheral surface of the lower end of the built-in tube 7 is provided with an axial slot 6, which is used to increase the discharge flow of the drainage fluid, especially when the drainage fluid is viscous, it can also prevent the drainage fluid from clogging. If a blockage occurs, not only does it increase medical expenses, time and effort, but also re-puncture increases the pain of the patient.

Operation steps of the present invention: (see Fig. 3, Fig. 4) First, the doctor clamps the upper stop clip 13 on the upper part of the built-in tube 7, the lower end of the built-in tube 7 is located inside the skin expander 1, selects the patient's puncture site and injects it The anesthetic is fully anesthetized, and the cone tip 3 is aligned with the puncture point and slowly rotated into the drainage site of the patient. Second, the doctor holds the skin expander 1 firmly with one hand to keep it fixed, and the other hand slowly presses the inner tube 7 so that the lower port opens the broken seam 4 on the peripheral wall of the conical tip 3. 3. (See Fig. 5) Reversely rotate the skin expander 1 to move upward along the built-in tube 7 away from the patient's body, and clamp the lower stop clip 14 on the built-in tube 7 below the skin expander 1. Fourth, remove the upper stop clip 13, in order to prevent the liquid in the built-in tube 7 from flowing out, a disposable syringe can be used to extract the internal liquid, and the skin expander 1 can be sleeved on the built-in tube 7 or withdrawn. Fifth, connect the liquid inlet 8 of the flexible drainage tube 9 to the upper end of the built-in tube 7, insert the liquid outlet 11 of the flexible drainage tube 9 into the fluid collection bag 12, remove the lower stop clip 14, and make the patient's serosal cavity The effusion inside enters into the effusion bag 12 through the built-in tube 7 and the drainage tube 9 .

In addition, the device can also take the following measures: First, increase the inner diameter of the skin expander 1 and the built-in tube 7 . Second, configure a suitable effusion tank or effusion bottle. Third, use a blade to cut a small incision on the patient's drainage skin at the beginning of the operation, so that the skin expander 1 can be screwed in conveniently. The above measures can enable the present invention to be used for the drainage of gas and gas-liquid mixture, and for the treatment of pneumothorax and hydropneumothorax.

According to the disclosure and teaching of the above description, those skilled in the art to which the apparatus 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 the convenience of description and do not constitute any limitation to the device of the present invention.
