Each of the two support blocks has symmetrically arranged springs fixedly connected to it, and pressure blocks are fixedly connected to the side walls of the clamping ring.

[0004] After the drainage tube is brought out from the body surface, it is often necessary to directly glue and fix the drainage tube to the skin surface with adhesive tape to prevent the tube from shifting, falling off or becoming infected. However, when removing the drainage tube, the adhesive tape on the skin surface needs to be peeled off first, which is not conducive to the removal of the drainage tube. Utility Model Content

[0005] The purpose of this invention is to provide a tumor fluid drainage device that facilitates convenient fixation of the drainage tube on the body surface.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tumor fluid drainage device, including a drainage bag, a drainage tube connected to the drainage bag at one end, and adhesive tape adhered to the skin surface. The adhesive tape has a connecting strip at one end fixed to the upper surface of the adhesive tape and used to cover the drainage tube. A Velcro female is provided at the end of the connecting strip away from the adhesive tape. A Velcro female is provided on the upper surface of the adhesive tape for the Velcro female to adhere. An air balloon tube with a C-shaped cross-section for the drainage tube to pass through is adhered and fixed on the inner wall of the connecting strip. An air tube leading out to the outside of the adhesive tape is provided at the end of the air balloon tube. An inflation / deflation assembly for inflating and deflating the air balloon tube is provided on the outside of the adhesive tape.

[0007] A further feature of this invention is that the inflation / deflation assembly includes a piston cylinder connected to the end of the air tube away from the airbag tube, a piston block embedded in the piston cylinder, a piston rod disposed on the piston block, and a pressure block disposed at the end of the piston rod away from the piston block.

[0008] A further feature of this invention is that an internal threaded ring is provided on the periphery of the pressure block, and an external threaded surface is provided on the outer periphery of the piston cylinder end for threaded connection of the internal threaded ring.

[0009] A further feature of this invention is that a positioning plate is fixed on the drainage tube for abutting against the side wall of the connecting strip.

[0010] A further feature of this invention is that a hanging ring is provided on the upper side of the drainage bag.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. When fixing the drainage tube on the skin, first stick the adhesive tape to the skin surface, then embed the drainage tube into the balloon tube of the connecting strap, then stick the Velcro nut of the connecting strap to the Velcro nut, then use the inflation and deflation assembly to inflate the balloon tube. After the balloon tube inflates, it will press against the drainage tube inside, thereby tightening and fixing the drainage tube. Finally, the drainage tube can be stably fixed on the adhesive tape.

[0013] When it is necessary to remove the drainage tube from the tape, simply use the inflation / deflation device to deflate the airbag tube, thereby loosening the drainage tube inside the airbag tube. Then, remove the Velcro nut from the Velcro nut, and then open the connecting strap to remove the drainage tube from the airbag tube. This will facilitate the convenient fixation of the drainage tube on the body surface.

[0014] 2. When it is necessary to inflate or deflate the airbag tube, simply press the pressure block to move the piston block inside the piston cylinder via the piston rod, thus completing the inflation or deflation of the airbag tube.

[0015] 3. After the piston block moves toward the piston cylinder and inflates toward the air bladder tube, the internal thread on the periphery of the pressure block is connected to the external thread surface outside the piston cylinder end to position the piston block inside the piston cylinder. This ensures stable air pressure inside the air bladder tube and stable tensioning of the drainage tube.

[0016] 4. The positioning plate fixed on the drainage tube can play a positioning role, preventing the part of the drainage tube in the body from shifting when the drainage bag or drainage tube is pulled.

[0017] 5. The drainage bag can be easily hung using the hanging loop on the upper side of the drainage bag. Attached Figure Description
