Description

TECHNICAL FIELD

[0001] The present application relates to the field of chest tube fixation, in particular to a chest tube fixation device. BACKGROUND

[0002] After thoracic surgery of a patient, a chest tube is generally inserted into the chest cavity, which can guide the pus, blood or other liquid 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 pull the wound of the patient under the action of gravity, so the chest tube generally needs to be fixed.

[0003] At present, some chest tube fixation devices are to pass the chest tube through several mutually articulated fixing blocks, and then rotate the adjacent fixing blocks to be perpendicular to each other to fix the chest tube. However, this has a problem that the bending position of the chest tube may cause stenosis or closed blockage, thereby affecting the smooth discharge of body fluid. SUMMARY

[0004] The present application aims to provide a chest tube fixation device to unblock the chest tube during the bending and fixing process, and ensure the smooth discharge of body fluid.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a chest tube fixation device, comprising a fixing patch, a base connected with the fixing patch, a bending seat rotationally connected with the base, and two unblocking mechanisms, the fixing patch, the base and the bending seat are all provided with through holes, each unblocking mechanism comprises a frame and two unblocking units above and below, the frame is fixed with the bending seat and located on one side of the base and in contact with the base; each unblocking unit comprises a ball, a pressing rod and an arc-shaped clamp, the frame is provided with a communicating arc-shaped rod slide and an arc-shaped ball slide, the arc-shaped ball slide is located in the middle of the arc-shaped rod slide, the upper ball is fixedly arranged in the arc-shaped ball slide, and the lower ball is slidingly arranged in the arc-shaped ball slide and magnetically attracted to the upper ball; the pressing rod is slidingly connected with the ball, the ball is provided with an annular groove, the pressing rod is provided with a clamping piece which can be clamped into the annular groove, the arc-shaped clamp is fixedly connected with the pressing rod and the lower arc-shaped clamp can clamp the chest tube and be magnetically attracted to the base, and the upper arc-shaped clamp can extrude the bent chest tube.

[0006] The beneficial effects of the present application are as follows: the chest tube outside the patient's body passes through the through holes of the fixing patch, the base and the bending seat in turn, when the patient is moving, the bending seat can be rotated to fix the chest tube, after rotating the bending seat by a certain angle, the patient can press the pressing rods on both sides of the base to move, so as to clamp the clamping piece into the annular groove to fix the pressing rod, at this time, the lower arc-shaped clamp clamps the chest tube and is magnetically attracted to the base, which prevents the wound from being pulled during further bending of the chest tube.

[0007] When the patient continues to rotate the bending seat, the two balls are separated, and the separated touch feeling, in combination with the contact with the base and the friction generated in the process of rotating the frame, facilitates the patient to master the force of rotating the bending seat, which is very useful for the patient who has not operated before, because the patient will worry that the grasping of the rotating force will affect the bending of the chest drainage tube.

[0008] In the process of rotating the bending seat, the upper arc-shaped clamp extrudes the side wall of the bent chest drainage tube, which is equivalent to the effect of pinching the chest drainage tube inward, thereby avoiding the narrowing or closure of the chest drainage tube, and ensuring the smooth discharge of body fluid; and in the process of rotating the bending seat, the friction generated between the arc-shaped ball slide and the lower ball and the arc-shaped rod slide and the lower pressing rod is transmitted to the bent part of the chest drainage tube through the pressing rod and the arc-shaped clamp, which promotes the body fluid to pass through the bent part, and further ensures the smooth discharge of body fluid.

[0009] After the chest drainage tube is bent, the upper arc-shaped clamp clamps the chest drainage tube, thereby further enhancing the fixing effect of the chest drainage tube and preventing the chest drainage tube from being pulled during the movement.

[0010] Further, the side walls of the arc-shaped rod slide and the arc-shaped ball slide are wavy.

[0011] Further, the frame is provided with a scale line, and the scale line can be aligned with the edge line of the base. The beneficial effects of the present scheme are as follows: during the process of rotating the bending block by the patient, when the scale line is aligned with the edge line of the base, the patient can smoothly move the pressing rod at this time.

[0012] Further, the clamping piece includes a spring and a hemisphere, and the pressing rod is provided with a blind hole, 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] Further, the ball is provided with a channel along the radial direction thereof, the pressing rod is slidably connected with the channel, a limiting groove is arranged on the channel, and a limiting block is arranged on the pressing rod and slidably arranged in the limiting groove.

[0014] Further, the base is detachably connected with the fixing patch.

[0015] Further, the bending seat is abutted with the base after being rotated by 90°.

[0016] Further, the base is provided with a groove, a hinge is arranged at the groove, and the bending seat is rotatably connected with the base through the hinge.

[0017] Further, the diameter of the through hole on the bending seat is greater than the diameter of the chest drainage tube. BRIEF DESCRIPTION OF DRAWINGS
