Description

Drainage tube fixer

Technical Field

The utility model relates to the field of medical equipment, particularly, relate to a drainage tube fixer.

Background

The drainage tube is widely used in the medical field, and the clinical surgical drainage tubes are various and are respectively used for thoracic drainage, brain cavity drainage, gastrointestinal drainage, biliary tract drainage, catheterization and the like. The surgical drainage aims to guide various effusion in human tissues or body cavities to the outside of a body, prevent postoperative infection and accelerate wound healing; on the other hand, the utility model is convenient for observing whether active bleeding or suture (anastomosis) leakage exists in the operation area after operation, and checking and monitoring the change of the character, quantity and component of various drainage fluids. A drainage tube commonly used in clinic is a tube made of medical plastic or rubber. In order to ensure the smoothness of the drainage tube, the drainage tube needs to be fixed after the operation. The common fixing mode is suture fixing by silk threads, but the suture operation is easy to increase tissue trauma and tissue infection chances, and the suture traction tissue is easy to cause pain for patients. In addition, tissue cutting is easily caused by long-time suture line dragging, tissue trauma is aggravated, and the suture line falls off after the tissue is cut off, and needs to be sutured again to fix the drainage tube. Further, many instruments are required for suturing and fixing, and the operation is inconvenient.

In view of the above disadvantages of the sewing method, the adhesive method is often used. For example, chinese patent application publication No. CN101130124 discloses a drainage tube fixer, which directly binds a drainage tube through a drainage tube binding band on an adhesive substrate sheet to fix the drainage tube. Although this approach eliminates the need to sew the drain tube to the patient's skin, tying the drain tube by a tie, if the tie is loose, the drain tube tends to fall off when the patient is moved, rolled over or taken up or lying down, which can affect drainage if the tie is tied. Chinese utility model patent publication No. CN2796719 discloses a drainage tube fixing sticker, which comprises a fixing section and a plurality of winding strips connected with the fixing section, and the drainage tube is fixed by winding the winding strips. Above-mentioned two kinds of drainage tube fixed mode, no matter directly bind or adopt the winding mode fixed through the bandage, its troublesome poeration, and inconvenient wound situation of looking over or handle the wound.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

Example 1

Referring to fig. 1 and 2, a drainage tube fixer comprises a patch 10 and a fixing component, wherein a through hole and a support rod penetrating through the through hole are arranged in the middle of the patch 10. The fixing assembly includes a base 20, a stand pipe 30, and a cap 40, and the base 20, the stand pipe 30, and the cap 40 are hollow cylindrical members so that the drainage tube can pass through the base 20, the stand pipe 30, and the cap 40. The base 20 is mounted on the support rod (the base may be integrally connected with the support rod, or may be connected in sections, which is not limited in this embodiment), and the stand pipe 30 is connected to the base 20 by screwing or fastening. In this embodiment, a clamping groove (not shown in the drawings) is disposed at an upper end of the base 20, a clamping structure matched with the clamping groove is disposed on an inner wall of a lower end of the vertical pipe 30, and the base 20 and the vertical pipe 30 are fastened or separated by the clamping structure. As another embodiment, the outer wall of the upper end of the base 20 is provided with external threads (not shown in the drawings), the inner wall of the lower end of the stand pipe 30 is provided with internal threads (not shown in the drawings), and the base 20 is screwed with the stand pipe 30. The end of the stand pipe 30 far away from the base 20 is provided with a plurality of elastic clamping jaws 31, the pipe cap 40 is connected with the stand pipe 30 in a rotating mode, the pipe cap 40 is in a cone frustum shape, and the clamping degree of the elastic clamping jaws 31 can be controlled by adjusting the rotating depth of the pipe cap 40. The elastic claw 31 is a multi-petal structure, and is folded to form a ring shape when being contracted, and the ring with different calibers can be formed by applying contraction force with different degrees to the ring. In this embodiment, the outer wall of the stand pipe 30 is provided with an external thread 32, the inner wall of the pipe cap 40 is provided with an internal thread 41 matched with the external thread 32, and the stand pipe 30 is connected with the pipe cap 40 through a thread. The patch 10 comprises a surface layer 11, an adhesive layer 12 contacting with human skin, and a ring part 13 for fixing the strut, wherein the ring part 13 is arranged between the surface layer 11 and the adhesive layer 12, and two ends of the strut are adhered to the ring part 13. The surface layer 11 of the patch 10 is also provided with a waterproof layer to prevent the surface of the patch 10 from being immersed in water.

Referring to fig. 2, the struts include a first strut 14 and a second strut 15 parallel to the first strut 14, and the outer wall of the lower end of the base 20 is connected to the first strut 14 and the second strut 15. The first support rod 14 is used for supporting a base 20, and the outer wall of the base 20 is connected with the first support rod 14 into a whole. The supporting rod is made of elastic materials, so that the supporting rod has certain elasticity, and when the supporting rod is in direct contact with the skin, the skin cannot be injured by compression.

Example 2

Referring to fig. 3 and 4, embodiment 2 is different from embodiment 1 in that the struts include a first strut 14 and a second strut 15 connected to the first strut 14, the first strut 14 is circular, the second strut 15 is radially distributed along the circumference of the first strut 14, and the lower end surface of the base 20 is connected to the first strut 14. The diameter of the circle formed by the first support rod 14 is the same as the inner diameter of the base 20, the lower end surface of the base 20 is connected with the first support rod 14 into a whole, and the base 20 is integrally supported by the first support rod 14.

Prior to use of the present drain holder, the stand pipe 30 is disconnected from the base 20, and the cap 40 is also disconnected from the stand pipe 30. In use, the drainage tube is passed through the base 20, the stand tube 30 and the cap 40, the patch 10 is adhered to a suitable position around the wound of the patient, then the stand tube 30 is fastened to the base 20, and the cap 40 is screwed to the stand tube 30. Since the diameter of the upper end of the cap 40 is smaller than that of the lower end, the cap 40 is rotated clockwise, and the cap 40 moves downward, causing the elastic jaws 31 to contract inward, clamping the drainage tube, thereby fixing the drainage tube. When the drainage tube is removed, the elastic claw 31 can be expanded outwards by screwing the tube cap 40 anticlockwise, and the clamping force on the drainage tube is released. The drainage tube fixer has good universality, is suitable for drainage tubes with various diameters, and adjusts the screwing degree of the tube cap 40 according to the diameter of the drainage tube so that the vertical tube 30 clamps the drainage tube.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
