Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a reinforcement device for fixing a chest drainage tube. Background Technology

[0002] Thoracic drainage is a routine treatment in general thoracic surgery. It typically involves inserting one end of a drainage tube into the pleural cavity, while the other end is connected to a drainage bottle or bag via an extension tube. However, in clinical practice, there are currently some problems with the methods of securing drainage tubes. When performing thoracic drainage, initial fixation is usually performed at the incision site, followed by a second fixation near the incision. Existing methods for this second fixation often involve using ropes or rubber bands to secure the drainage tube, and then attaching it to the patient's body with tape. While this method is relatively simple, it has several drawbacks. First, the fixation effect of ropes or rubber bands is limited; with increased use, friction between the drainage tube and the rope can cause the rope to gradually loosen, and friction between the rope and the tape can easily cause the tape to detach. Second, the procedure is inconvenient; adjusting the tightness of the fixation requires re-applying the tape, which undoubtedly increases the difficulty of care. Furthermore, repeated application and removal of tape can easily cause skin allergies or damage. Utility Model Content

[0003] The present invention aims to provide a reinforcement device for fixing chest drainage tubes, so as to solve the problems of poor fixation effect and easy loosening and falling off of existing drainage tubes.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reinforcement device for fixing a chest drainage tube, comprising a base and a fixing sleeve. An adhesive plate is fixedly connected to the bottom end of the base. An arc-shaped groove is formed at the top end of the base. Two fixing devices are symmetrically arranged within the arc-shaped groove. Each fixing device includes three connecting columns. The arc-shaped groove has three sliding grooves that mate with the connecting columns. The three sliding grooves are slidably connected to the three connecting columns respectively. The three sliding grooves are evenly distributed on the arc-shaped groove. A fixing block is fixedly connected to the top end of each of the three connecting columns. A sliding hole is formed in the middle section of the side wall of each connecting column. A movable groove is formed inside the base. A pull rope is provided within the movable groove. Both ends of the pull rope are fixedly connected to the top sides of the movable groove near the arc-shaped groove. A through hole is formed near the position of the movable groove near the arc-shaped groove. The through hole connects to the outside from the side wall of the base. The pull rope passes through the sliding hole of the three connecting columns and exits through the through hole. The fixing sleeve has two fixing holes. The free ends of the pull ropes of the two fixing devices pass through the two fixing holes respectively.

[0005] Preferably, the top of the adhesive plate is made of silicone, and the bottom of the adhesive plate is made of hydrogel.

[0006] Preferably, the top of the fixing block is made of silicone.

[0007] Preferably, the diameter of the fixing hole is slightly smaller than the diameter of the pull cord.

[0008] Preferably, the base and the fixing sleeve are made of medical-grade plastic.

[0009] The principle and beneficial effects of this technical solution:

[0010] By combining the base, adhesive plate, fixing device, and pull cord, the drainage tube is securely fixed by utilizing the high friction between the hydrogel of the adhesive plate and the skin, as well as the clamping effect of the silicone fixing block. Specifically, the hydrogel material at the bottom of the adhesive plate adheres tightly to the skin, providing strong adhesion and effectively preventing the device from shifting during use. The silicone material at the top of the adhesive plate provides a soft and highly frictional contact surface for the drainage tube, ensuring that it will not damage the tube while preventing it from easily slipping during fixation.

[0011] The fixing device is slidably connected to the sliding groove within the arc-shaped slot via three connecting posts, allowing the fixing block to be flexibly adjusted to accommodate drainage tubes of different diameters. The sliding hole in the middle section of the connecting post sidewall, in conjunction with the pull rope, ensures that the fixing block tightly clamps the drainage tube when the pull rope is pulled, further enhancing the stability of the fixation. Furthermore, the diameter of the fixing hole is slightly smaller than the diameter of the pull rope; this design ensures that the pull rope will not easily slip off during the fixing process, thus guaranteeing the reliability of the fixation effect.

[0012] The device in this technical solution is simple to operate and easy to use. In actual use, simply place the device on the patient's skin; the close adhesion of the hydrogel to the skin and the secondary fixation with 3M adhesive ensure the device's stability. Then, place the drainage tube in the arc-shaped groove, and quickly fix the drainage tube by pushing the fixing sleeve and pulling the pull cord. After fixation, the fixation effect can be confirmed by gently moving the drainage tube. If the fixation effect is unsatisfactory, continue pulling the pull cord for adjustment until a satisfactory fixation effect is achieved. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0018] Example:

[0019] like Figures 1-2 The diagram illustrates a reinforcement device for fixing a chest drainage tube. The device mainly comprises a base and a fixing sleeve. An adhesive plate is fixedly connected to the bottom of the base, and an arc-shaped groove is formed at the top. Two fixing devices are symmetrically arranged within the arc-shaped groove. Each fixing device consists of three connecting columns, which are slidably connected to sliding grooves within the arc-shaped groove. The sliding grooves are evenly distributed on the arc-shaped groove. A fixing block is fixedly connected to the top of each connecting column, and a sliding hole is formed in the middle of its side wall. A movable groove is provided inside the base, and a pull rope is installed within the movable groove. The two ends of the pull rope are fixed to the top sides of the movable groove near the arc-shaped groove. A through hole is formed near the arc-shaped groove in the movable groove, connecting to the outside from the side wall of the base. The pull rope passes through the sliding hole of the connecting column and exits the device through the through hole. Two fixing holes are formed on the fixing sleeve, and the free ends of the pull ropes of the two fixing devices pass through the two fixing holes respectively.

[0020] The adhesive plate has a silicone top and a hydrogel bottom. The silicone material provides greater friction against the drainage tube wall and is soft, preventing deformation or damage. The hydrogel adheres tightly to the skin, providing strong adhesion and preventing movement during use. The fixing block also has a silicone top, further enhancing the clamping effect on the drainage tube.

[0021] The specific implementation process is as follows:

[0022] First, the device is placed on the patient's skin, using the high friction between the hydrogel and the skin to ensure initial fixation. Then, 3M adhesive is used to further secure the device to the patient's skin through the tip of the adhesive plate, enhancing its stability. Figure 3 Next, place the drainage tube in the arc-shaped groove, push the fixing sleeve towards the base, and simultaneously pull the pull rope in the opposite direction to clamp the drainage tube with the fixing block, thus achieving a stable fixation of the drainage tube. The diameter of the fixing hole is slightly smaller than the diameter of the pull rope. This design ensures that the pull rope will not easily slip during the fixing process, thereby guaranteeing the reliability of the fixing effect. After fixing, the drainage tube can be gently moved by hand to confirm the fixing effect. If the fixing effect is good, the two pull ropes can be tied with knots to complete the final fixation; if the fixing effect is not good, continue to gently pull the pull ropes for adjustment until the desired effect is achieved.

[0023] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solution of this utility model, and these should also be considered within the scope of protection of this utility model.
