Description

Technical Field

[0001] The present invention relates to the field of chest tube fixation, and in particular to a chest tube fixation device. Background Art

[0002] After thoracic surgery, a chest tube is usually inserted into the chest cavity. The chest tube can drain the pus, blood or other fluids accumulated in the chest cavity to the outside of the body, preventing postoperative infection and promoting wound healing. When the patient is moving, the chest tube may cause a certain amount of pulling on the patient's wound under gravity, so the chest tube generally needs to be fixed.

[0003] Currently, some chest tube fixation devices thread the chest tube through several hinged fixing blocks, then rotate adjacent fixing blocks perpendicular to each other to secure the chest tube. However, this method poses a problem: the bend in the chest tube may cause stenosis or closure, thus affecting the smooth drainage of body fluids. Summary of the Invention

[0004] The present invention aims to provide a chest tube fixing device to dredge the chest tube during the bending and fixing process to ensure smooth discharge of body fluids.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a chest tube fixing device, comprising a fixing patch, a base connected to the fixing patch, a bending seat rotatably connected to the base, and two dredging mechanisms, wherein the fixing patch, the base, and the bending seat are all provided with through holes, and each dredging mechanism comprises a frame and two upper and lower dredging units, wherein the frame is fixed to the bending seat and is located on one side of the base and in contact with the base; each dredging unit comprises a ball, a pressing rod, and an arc-shaped clamp, and the frame is provided with a connected arc-rod slideway and an arc-ball The slide, the arc ball slide is located in the middle of the arc rod slide, wherein the upper sphere is fixed in the arc ball slide, and the lower sphere is slidably set in the arc ball slide and is magnetically attracted to the upper sphere; the pressing rod is slidably connected to the sphere, and an annular groove is provided in the sphere. The pressing rod is provided with a clamping piece and the clamping piece can be clamped into the annular groove. The arc clamp is fixedly connected to the pressing rod and the arc clamp located at the bottom can clamp the chest tube and be magnetically attracted to the base, and the arc clamp above can squeeze the bent chest tube.

[0006] The beneficial effects of this solution are as follows: the chest drainage tube outside the patient's body passes through the through holes on the fixing patch, the base and the bending seat in sequence. When the patient moves, the bending seat can be rotated to fix the chest drainage tube. After rotating the bending seat to a certain angle, the patient can press the pressing rods on both sides of the base to move, thereby snapping the connecting parts into the annular groove to fix the pressing rods. At this time, the arc-shaped clamp located below clamps the chest drainage tube and is magnetically attracted to the base, preventing pulling on the wound during further bending of the chest drainage tube.

[0007] When the patient continues to rotate the bending seat, the two spheres separate. The feeling of separation and the friction generated by the contact with the base during the rotation of the frame make it easy for the patient to grasp the force of rotating the bending seat. This is very useful for patients who have never operated it before, because patients may worry that the poor control of the rotation force will affect the bending of the chest tube.

[0008] During the rotation of the bending seat, the upper arc-shaped clamp squeezes the side wall of the bent chest tube, which is equivalent to pinching the chest tube inward, thereby avoiding stenosis or closure of the chest tube and ensuring smooth discharge of body fluids; and during the rotation of the bending seat, the friction and vibration generated by the arc-shaped ball slide and the lower ball, and the arc-shaped rod slide and the lower pressing rod will be transmitted to the bending part of the chest tube through the pressing rod and the arc-shaped clamp, promoting the passage of body fluids through the bending part, and further ensuring smooth discharge of body fluids.

[0009] After the chest tube is bent, the arc-shaped clamp on the top clamps the chest tube, thereby further strengthening the fixation effect of the chest tube and preventing the wound from being pulled during movement.

[0010] Furthermore, the side walls of the curved rod slide and the curved ball slide are wavy.

[0011] Furthermore, the frame is provided with scale lines, which can be aligned with the corner lines of the base. The beneficial effect of this solution is that when the patient rotates the bending block, when the scale lines are aligned with the corner lines of the base, the patient can smoothly press the pressing rod to move.

[0012] Furthermore, the clamping member includes a spring and a hemisphere, a blind hole is provided on the pressing rod, one end of the spring is fixed to the bottom of the blind hole, and the other end of the spring is fixed to the hemisphere.

[0013] Furthermore, the sphere is provided with a channel along its radial direction, the pressing rod is slidably connected to the channel, a limiting groove is provided on the channel, the pressing rod is provided with a limiting block, and the limiting block is slidably arranged in the limiting groove.

[0014] Furthermore, the base and the fixing sticker are detachably connected.

[0015] Furthermore, the bending seat is rotated 90 degrees and then abuts against the base.

[0016] Furthermore, a groove is provided on the base, a hinge is provided at the groove, and the bending seat is rotatably connected to the base through the hinge.

[0017] Furthermore, the diameter of the through hole on the bending seat is larger than the diameter of the chest tube. BRIEF DESCRIPTION OF THE DRAWINGS
