Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a ventricular drainage tube clamping device. Background Art

[0002] Drainage tubes are used for clinical surgical drainage. They are used to guide pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. Drainage tubes are often used in ventricular drainage operations. Commonly used drainage tubes require a clamping device to fix the drainage tube during operation to limit the movement of the drainage tube.

[0003] During ventricular drainage, a clamp is often used to directly clamp the drainage tube. Because the drainage tube has bending plasticity, when the clamping force is too large, it is easy to cause deformation of the drainage tube, affecting the drainage flow. On the contrary, when the clamping force is small, it cannot meet the stability of the drainage tube limit. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combined with reference Figure 1-Figure 4 The utility model provides a ventricular drainage tube clamping device, including a fixed bracket 1, a fixed structure 2 is arranged on the fixed bracket 1, a pair of tubes 3 are fixedly connected to the fixed bracket 1, and each tube 3 is provided with a pipe opening 31 for the ventricular drainage tube to enter and exit. Without moving the positions of the two ends of the drainage tube, the tube 3 can be directly entered and exited through the pipe opening 31, a pair of tubes 3 are fixedly connected with a clamping rod 32, and the clamping rod 32 can be used for the support of the drainage tube to be fixed, each tube 3 is rotatably connected with a rotating ring 4, and the rotating ring 4 is provided with a first notch, and the first notch can cooperate with the pipe opening 31 to pass the drainage tube, a pair of rotating rings 4 are fixedly connected with a winding structure 5, and a fixed winding belt 6 is wound on the winding structure 5, and one end of the fixed winding belt 6 is fixedly connected to the clamping rod 32, and a rotating driving unit 7 for driving the rotating ring 4 to rotate is arranged on the fixed bracket 1.

[0023] The fixing structure 2 includes a holder 21 fixedly connected to the fixing bracket 1 and a fastening bolt 22 threadedly passing through the holder 21. The holder 21 can cooperate with the fastening bolt 22 to clamp the mounting surface, so that the position of the fixing bracket 1 to provide support for the drainage tube can be stabilized.

[0024] The outer surface of the tube 3 is fixedly connected with a slip ring 8 , and the rotating ring 4 is slidably connected to the slip ring 8 . The slip ring 8 can provide rotation and support for the rotating ring 4 , and a third notch matching the size of the pipe opening 31 is provided on the slip ring 8 .

[0025] The winding and unwinding structure 5 includes a storage box 51, a shaft 52 fixedly connected to the storage box 51, a winding drum 53 rotatably connected to the shaft 52, and a spiral spring 54 sleeved on the shaft 52, wherein the inner end of the spiral spring 54 is fixedly connected to the shaft 52, and the outer end of the spiral spring 54 is fixedly connected to the winding drum 53, each rotating ring 4 is fixedly connected to a fixed rod 9, and the storage box 51 is fixedly connected to a pair of fixed rods 9. The arrangement of the spiral spring 54 can give the winding drum 53 rotational tension when the winding drum 53 rotates forward and reverse, so that there is a tensioning effect when the fixed winding belt 6 is wound and released, so that the tightness of the fixed winding belt 6 can be guaranteed when the fixed winding belt 6 is constrained and clamped to clamp the drainage tube.

[0026] The fixed winding tape 6 is wound on the winding drum 53 , and a tape insertion opening 10 for the fixed winding tape 6 to pass through is opened on the storage box 51 , and the tape insertion opening 10 can be limited to allow the fixed winding tape 6 to pass through.

[0027] Specifically, after the drainage tube is placed in a pair of tubes 3, the storage box 51 is driven by the rotation drive unit 7 to rotate in a circle around the center of the tube 3. Since one end of the fixed winding belt 6 is fixed on the clamping rod 32, the rotation of the storage box 51 can make the fixed winding belt 6 be wound on the clamping rod 32. Since the spiral spring 54 has a bending elastic force, when the winding drum 53 rotates on the shaft rod 52 to unwind the fixed winding belt 6, the fixed winding belt 6 can first bind the drainage tube to the clamping rod 32 and wind it layer by layer to tighten the drainage tube on the clamping rod 32 to complete the clamping and fixing. In this way, the uniformity of the force clamping of the drainage tube can be ensured, and while stabilizing the fixed position, the problem of clamping deformation can be avoided.

[0028] Similarly, by driving the storage box 51 to rotate in the opposite direction through the rotating drive unit 7, the fixed winding belt 6 can release the winding of the drainage tube, and utilize the elastic force of the bending spiral spring 54 so that the fixed winding belt 6 can be conveniently wound onto the winding drum 53. By releasing the clamping of the drainage tube by the fixed winding belt 6, the drainage tube in the tube tube 3 can be easily taken out.

[0029] The rotary drive unit 7 includes a support plate 71 fixedly connected to the fixed bracket 1, three gears 72 rotatably connected to the support plate 71, a toothed ring 74 meshingly connected to the two gears 72 located on both sides, and a motor 73 fixedly connected to the support plate 71. The three gears 72 are meshedly connected in sequence, the output end of the motor 73 is fixedly connected to the gear 72 located in the middle, the toothed ring 74 is fixedly connected to one of the rotating rings 4, and the motor 73 in the present application can be used in conjunction with a miniature worm gear reducer. By giving the motor 73 a self-locking property, the toothed ring 74 can be prevented from rotating. By driving one of the gears 72 to rotate through the motor 73, the meshing motion of the other two gears 72 can achieve the same direction, so that the toothed ring 74 can be driven to rotate at the same time, and the toothed ring 74 can drive the winding and unwinding structure 5 through the rotating ring 4 to perform a circular motion of winding and unwinding the fixed winding belt 6.

[0030] A second notch is provided on the gear ring 74, and the gear ring 74 can accommodate the pipe opening 31 to enter and exit the drainage tube. Since the second notch is provided on the gear ring 74, three gears 72 are provided for transmission coordination, wherein two gears 72 rotate in the same direction and mesh with the gear ring 74, so that the second notch of the gear ring 74 can be easily transitioned to ensure the stability of the transmission of the gear ring 74.
