Description

Technical Field

[0001] The present invention relates to the technical field of effusion drainage, and specifically relates to an effusion drainage device for postoperative care in hepatobiliary surgery. Background Art

[0002] In the field of hepatobiliary surgery, after hepatobiliary surgery, inflammatory effusion, pus, blood, or leaked digestive fluid will be generated in the patient's body. If not drained out in time, it will not only hinder wound healing, but also easily cause serious complications such as infection, which will have a great negative impact on the patient's recovery process.

[0003] The existing effusion drainage devices generally directly insert a drainage tube and form a negative pressure through an external negative pressure device for extraction. When the nozzle of the tube exerts suction, it is easy to adsorb the human flesh and blood near the nozzle, thus blocking the nozzle and causing discomfort or secondary injury to the human body. Therefore, it is necessary to propose an effusion drainage device for postoperative care in hepatobiliary surgery. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides an effusion drainage device for postoperative care in hepatobiliary surgery.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an effusion drainage device for postoperative care in hepatobiliary surgery, including a drainage tube, one end of the main tube is fixedly connected with a spherical filter net,

[0006] A support rod is fixedly installed on the tube wall of the drainage tube. The upper end of the support rod is fixedly connected with a support ball. A lifting cavity is opened inside the support ball. A threaded hole is penetrated through the support rod. A threaded rod is threadedly connected in the threaded hole. The upper end of the threaded rod extends into the lifting cavity and is rotationally connected with a pushing block through a bearing. The pushing block is made of magnet. A first moving hole is penetrated through the spherical filter net. A second moving hole is penetrated through the lifting cavity. A moving block is slidably connected in the second moving hole. The moving block is made of iron and is adsorbed to the pushing block. The other end of the moving block is fixedly connected with a filter net cylinder. One end of the filter net cylinder away from the moving block is fixedly connected with a sealing plate. A blocking ring is fixedly sleeved on the outer side wall of the filter net cylinder.

[0007] Specifically, the end of the support rod away from the support ball extends outside the drainage tube. An installation block is fixedly sleeved on the rod wall of the support rod outside the drainage tube. An installation screw hole is opened on the installation block.

[0008] Specifically, the lower end of the threaded rod extends outside the support rod. One end of the threaded rod outside the support rod is fixedly connected with a handle.

[0009] Specifically, a fixing rod is fixedly connected to the outer side wall of the supporting ball, and one end of the fixing rod away from the supporting ball is fixedly connected to the inner wall of the spherical filter net.

[0010] Specifically, there are five first moving holes and five second moving holes, and the five first moving holes and the five second moving holes are respectively arranged on the outer side walls and the top wall of the spherical filter net and the supporting ball.

[0011] Specifically, the outer side wall of the sealing plate fits with the outer side wall of the spherical filter net.

[0012] Specifically, the first moving hole and the corresponding second moving hole are arranged in parallel.

[0013] Specifically, the pushing block is arranged in a semi-spherical shape, and four of the moving blocks are adsorbed to the pushing block to transfer magnetic force and are adsorbed to the other moving block.

[0014] The beneficial effects of the present invention: For the fluid drainage device for postoperative nursing in hepatobiliary surgery described in the present invention, when in use, the spherical filter net separates the flesh and blood from the pipe orifice of the main pipe, avoiding blockage caused by the pipe orifice attracting flesh and blood. When the flesh and blood cover the spherical filter net and affect drainage, by rotating the threaded rod to drive the pushing block to rise, and the pushing block pushes the moving block, the filter net cylinder and the sealing plate outwards. It will open up a gap in the flesh and blood near the spherical filter net, and continue to absorb the exudate through the filter net cylinder and the spherical filter net near the opened gap, avoiding affecting the absorption of exudate and causing discomfort to the human body.

Detailed implementation manners

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0025] As Figures 1 - 7 shown, the present invention provides the following technical solutions:

[0026] Example 1: A drainage device for postoperative care in hepatobiliary surgery, including a drainage tube 1, one end of the drainage tube 1 is fixedly connected with a spherical filter mesh 2,

[0027] During use, the spherical filter mesh 2 is placed at the position where the patient's exudate accumulates. The spherical filter mesh 2 isolates the human flesh and blood outside the spherical filter mesh 2, and the exudate will enter the spherical filter mesh 2 after filtration. Then, the drainage tube 1 is connected to an external negative pressure drainage device, and then the negative pressure drainage device is started. The negative pressure drainage device pumps the exudate that has entered the spherical filter mesh 2 through the drainage tube 1, avoiding the situation that when the drainage tube 1 extracts the exudate, it will pull the flesh and blood into the pipe orifice of the drainage tube 1, causing blockage and discomfort to the patient.

[0028] Embodiment 2: The technical solution of this embodiment different from that of Embodiment 1 includes: A support rod 3 is fixedly installed on the pipe wall of the drainage tube 1. The upper end of the support rod 3 is fixedly connected to a support ball 4. A lifting cavity 5 is opened inside the support ball 4. A threaded hole 6 is penetrated through the support rod 3. A threaded rod 7 is threadedly connected inside the threaded hole 6. The upper end of the threaded rod 7 extends into the lifting cavity 5 and is rotatably connected to a pushing block 8 through a bearing. The pushing block 8 is made of magnet. A first moving hole 9 is penetrated through the spherical filter net 2. A second moving hole 10 is penetrated through the lifting cavity 5. A moving block 11 is slidably connected inside the second moving hole 10. The moving block 11 is made of iron and is adsorbed to the pushing block 8. The other end of the moving block 11 is fixedly connected to a filter net cylinder 12. One end of the filter net cylinder 12 away from the moving block 11 is fixedly connected to a sealing plate 13. A blocking ring 14 is fixedly sleeved on the outer side wall of the filter net cylinder 12.

[0029] When the flesh and blood of the patient covers the spherical filter net 2 and affects the drainage of exudate, by rotating the threaded rod 7, the threaded rod 7 rises inside the threaded hole 6. When the threaded rod 7 rises, it will drive the pushing block 8 to rise synchronously through the bearing. When the pushing block 8 rises, it will push the moving block 11, the filter net cylinder 12 and the sealing plate 13. The moving block 11, the filter net cylinder 12 and the sealing plate 13 move outward from the spherical filter net 2 along the tracks of the first moving hole 9 and the second moving hole 10. The filter net cylinder 12 and the sealing plate 13 will extend outside the spherical filter net 2. The sealing plate 13 will prop up the flesh and blood to form a gap, avoiding the flesh and blood from covering the spherical filter net 2. At this time, the drainage tube 1 drains the exudate through the spherical filter net 2 and the filter net cylinder 12 at the gap.

[0030] After the drainage is completed, rotate the threaded rod 7 in the reverse direction. The threaded rod 7 pulls the pushing block 8 to descend through the bearing. When the pushing block 8 descends, it will pull the moving block 11 to reset by magnetic force, so that the moving block 11, the filter net cylinder 12 and the sealing plate 13 are reset, and the surface of the spherical filter net 2 returns to be flat, avoiding discomfort to the patient caused by long-term protrusion.

[0031] Embodiment 3: The technical solution of this embodiment different from that of Embodiment 1 includes:

[0032] Wherein, one end of the support rod 3 away from the support ball 4 extends outside the drainage tube 1. An installation block 15 is fixedly sleeved on the rod wall of the support rod 3 located outside the drainage tube 1. An installation screw hole 16 is opened on the installation block 15. The installation block 15 can be installed through the installation screw hole 16, and the installation block 15 supports the support rod 3 and the support ball 4.

[0033] Wherein, the lower end of the threaded rod 7 extends outside the support rod 3. One end of the threaded rod 7 located outside the support rod 3 is fixedly connected to a handle 17. It is more simple and convenient to rotate the threaded rod 7 through the handle 17.

[0034] Wherein, a fixing rod 18 is fixedly connected to the outer side wall of the supporting ball 4, and one end of the fixing rod 18 away from the supporting ball 4 is fixedly connected to the inner wall of the spherical filter net 2, and the supporting ball 4 supports the spherical filter net 2 through the fixing rod 18.

[0035] Wherein, both the first moving holes 9 and the second moving holes 10 are provided with five, and the five first moving holes 9 and the five second moving holes 10 are respectively arranged on the outer side walls and the top wall around the spherical filter net 2 and the supporting ball 4, so that when the filter net cylinder 12 and the sealing plate 13 are pushed outwards, the flesh and blood at the surrounding and top positions are pushed open respectively.

[0036] Wherein, the outer side wall of the sealing plate 13 coincides with the outer side wall of the spherical filter net 2, so that the surface of the spherical filter net 2 is flat to avoid discomfort.

[0037] Wherein, the first moving hole 9 and the corresponding second moving hole 10 are arranged in parallel.

[0038] Wherein, the pushing block 8 is arranged in a semi-spherical shape, and four of the moving blocks 11 are adsorbed to the pushing block 8 and transmit magnetic force, and are adsorbed to the other moving block 11.
