      ABSTRACT

      Objective: Drainage tubes (e.g., intracranial, abdominal cavity and thoracic) are commonly used to drain blood and fluid collections after surgery. It usually fails due to the lack of fixation perpendicular to the skin and the variety of tube materials. The objective of the article is to describe a new drainage tube device.

      Methods: This new device consists of a drainage tube fixator and diverter with a rotating handle. The fixator and diverter are fixed to the skin with a pair of wings, and the base comprises acircular arc with chamfering of the edge. The removable stopper and plastic diverter have a memory function. There are 2 holes on either side of the wings, by which they can be sewn to the skin or stapled for strength and stability.

      Results: The removable limiting stopper and plastic diverter with memory function work together to ensure that the drainage tube is firmly fixed. Therefore, the tube will not move either vertically or horizontally on the skin. Moreover, the device is fit for drainage tubes with different specifications and materials.

      Conclusions: The limiting stopper can be moved easily, which is conducive to local skin disinfection around the drainage tube. The device deserves clinical promotion.

      Drainage tubes (e.g., intracranial, abdominal cavity, and thoracic) are commonly used to drain blood and fluid collections after surgery. Drainage tubes are mostly made from medical plastic or rubber[1], and are sewn to the skin. However, these usually fail due to the lack of fixation perpendicular to the skin and the variety of tube materials. The tube can fall out or penetrate even deeper into the brain, which can lead to inade‐quate drainage, bleeding, infection, delayed healing, or even secondary puncture and repeat surgery[2–4]. Significant drain movement can endanger a patient’s life[5, 6]. Not only does pain increase, but medical resources are also wasted. In addition, almost all drainage tube devices in present clinical use only attach to a single drainage tube material, and the specifications are limited. Thus, the useful range is narrow. To address these problems, we designed a new device, consisting of a drainage tube fixator and diverter with a rotating handle (Figure 1).

      The drainage tube fixator and diverter are made of plastic and contain a pair of skin‐fixation wings, a base with a circular arc and chamfering of the edge, a removable stopper, and a plastic diverter with memory function (Figure 2). There are 2 holes on either side of the skin‐fixation wings, through which the wings can be sewn to the skin or stapled for strength and stability. A base with a circular arc and chamfering of the edge can effectively avoid trauma caused bycontact. There is a groove between the intines inside the base. The limiting stopper can be moved in the base by rotating the thread (Figures 3 and 4). As a result, the device can be used with tubes of different specifications and materials. The stopper firmly fixes the tube to the skin exit and prevents both vertical and horizontal movement on the skin. The groove in the plastic diverter with memory function forms a round downward hole. After tube placement, elastic closure due to the memory function will fix the tube, which makes it convenient to insert and remove.

      How is the device used? First, the drainage tube and surrounding skin are cleaned. Second, the base is fixed to the skin using the wings. The tube is then inserted through the hole and the rotating handle is used to move the limiting stopper towards the opposite side until the tube is pinched. This will prevent the tube from moving perpendicular to the skin. Finally, the tube is bent and inserted into the plastic diverter with memory function to prevent horizontal movementon the skin. Our experience shows that the new drainage tube device has a feasible design. In addition to being sewn or stapled to the skin, the removable stopper and plastic diverter with memory function work together to ensure that the drainage tube is fixed firmly (Figure 5). Therefore, the tube will not move either perpendicular or horizontal to the skin. In addition, the fixture can be used with drainage tubes with different specifications and materials. The limiting stopper can be moved easily, which enables local skin disinfection around the drainage tube. In conclusion, the device deserves clinical promotion.
