[0008] To achieve the above object, the present invention also provides the following technical solutions: An implantable infusion port detection device, comprising a base, one side of the base is connected with a connecting plate, the other side of the base is connected with a column, a fixing hoop is fixedly connected to the column, a chute is opened on the column, a rack is slidably connected to the column, one end of the rack is connected with a cross arm, a liquid storage bottle is installed above the cross arm, a pressure detector is connected below the cross arm, and a liquid pump is installed above the cross arm;

[0009] Two connecting pipes are connected to the liquid pump, a pressure sensor is electrically installed on the pressure detector, a communicating pipe is connected to the pressure detector, a threaded rod is threadedly connected to the connecting plate, a hand wheel is connected to one end of the threaded rod, and a clamping plate is rotatably connected to the other end of the threaded rod. An activity plate is slidably connected to the fixing hoop, a pulling plate is connected to one side of the activity plate, and a tooth block is connected to the other side of the activity plate.

[0010] As a further solution of the present invention: A connecting strip is connected to one side of the rack, the connecting strip is integrally designed in a T shape and is connected to the cross arm, the connecting strip is slidably connected to the chute, and the rack is engaged with the tooth block.

[0011] As a further solution of the present invention: A first anti-slip pad is connected below the base, a second anti-slip pad is connected above the clamping plate, two guide rods are connected to the clamping plate, the two guide rods are located on both sides of the threaded rod, and the guide rods are slidably connected to the connecting plate.

[0012] As a further solution of the present invention: A liquid injection pipe is connected to one side of the liquid storage bottle, the liquid pump is connected to the inside of the liquid storage bottle through one connecting pipe, and the liquid pump is connected to the communicating pipe through the other connecting pipe, and the pressure sensor is arranged between the connecting pipe and the communicating pipe.

[0013] As a further solution of the present invention: A fixing rod is connected to the fixing hoop, a buckle plate is rotatably connected to the pulling plate through a pin shaft, torsion springs are connected to both sides of the buckle plate, one end of the torsion spring is connected to the pulling plate, and an arc-shaped groove is arranged on the buckle plate and is engaged with the fixing rod.

[0014] The using method of the implantable infusion port detection device, the using method comprises the following steps:

[0015] By placing the base on the medical desk, at this time, medical staff can rotate the threaded rod by turning the hand wheel, so that the threaded rod pulls the clamping plate to move upward, so that the clamping plate can contact the edge of the desk, so that the clamping plate cooperates with the base to clamp and fix the edge of the desk, and the base is fixed on the medical desk to avoid accidental sliding and falling damage. After that, medical staff can rotate the buckle plate to make the buckle plate disengage from the fixing rod;

[0016] Furthermore, the movable plate is pulled by the pull plate to slide on the fixed hoop, causing the tooth block to move away from the rack, so that medical staff can push the cross arm to make the connecting bar and the rack slide in the column along the chute. Then, by pushing the movable plate, the tooth block and the rack are engaged with each other, thereby fixing the position of the rack to prevent it from sliding down.

[0017] When the snap plate is rotated, the torsion spring will be twisted. Thus, after the tooth block and the rack are engaged, the snap plate is released, and the torsion spring rotates to make the snap plate buckle on the fixed rod through the arc groove on one side, thereby fixing and limiting the movable plate to prevent accidental sliding from causing the tooth block to disengage from the rack. Furthermore, the height adjustment of the pressure detector is completed to facilitate the medical staff to observe and use. Then, the medical staff connects an infusion pipeline to one end of the communicating pipe, and makes the injection needle on the infusion pipeline pierce through the diaphragm and extend into the liquid injection cavity.

[0018] After that, the liquid pump is started, and the liquid pump extracts the normal saline in the storage bottle through the connecting pipe connected to the storage bottle and transports it to the communicating pipe through another connecting pipe. At this time, the pressure sensor senses and detects the pressure of the normal saline. The normal saline is transported to the liquid injection cavity through the infusion pipeline and flows into the catheter from the liquid injection cavity. If the catheter is blocked, the hydraulic pressure in the catheter, the communicating pipe and the infusion pipeline will change and be detected by the pressure sensor and transmitted to the pressure detector, thus facilitating the staff to detect whether the catheter is blocked to ensure the normal progress of the treatment.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, by setting the positioning ring, the first magnet, the second magnet, the first protective film, the second protective film and the toothed ring, the cover is screwed to be threadedly connected with the housing, so that the cover and the housing clamp and fix the diaphragm. At this time, the toothed rings in the cover and the housing will bite the diaphragm, thereby preventing the diaphragm from moving and making the diaphragm seal the cover and the housing. After the infusion port is implanted under the patient's skin, medical staff can hold the positioning ring close to the cover, so that the first magnet and the second magnet can adsorb each other, thereby combining the positioning ring and the cover together, and making the positioning ring located on the patient's skin surface. Thus, medical staff can find the specific position of the diaphragm by observing the position of the positioning ring, which is convenient for medical staff to perform puncture and infusion treatment. The first protective film and the second protective film can prevent the first magnet and the second magnet from directly contacting the skin and prevent adverse reactions.

[0021] 2. In the present invention, by providing a chute, a connecting bar, a rack, a toothed block, a fixing hoop, a movable plate, a fixing rod, a snap plate and a torsion spring, the medical staff first rotates the snap plate to disengage the snap plate from the fixing rod, and then pulls the movable plate to move the toothed block away from the rack, enabling the medical staff to push the cross arm, so that the connecting bar and the rack can slide in the column along the chute. Then, the movable plate is pushed to engage the toothed block with the rack, thereby fixing the rack to complete the height adjustment of the pressure detector for the convenience of the medical staff to observe and use. When the snap plate is rotated, the torsion spring will be twisted, and thus the torsion spring's rotation is utilized to make the snap plate latch onto the fixing rod through the arc-shaped groove to fix and limit the movable plate, preventing accidental sliding and causing the toothed block to disengage from the rack.

[0022] 3. In the present invention, by providing a handwheel, a threaded rod, a clamping plate and a second anti-slip pad, the medical staff rotates the threaded rod by turning the handwheel, causing the threaded rod to pull the clamping plate upward. At this time, the guide rod will slide on the connecting plate, so that the clamping plate cooperates with the base to clamp and fix the edge of the table, fixing the base on the medical table, thereby preventing the base from sliding. The operation is simple and convenient for the medical staff to place and fix. When the clamping plate clamps the edge of the table, the second anti-slip pad will be in contact with the table edge, thereby increasing the friction and improving the stability of the clamping.

[0033] The present invention also provides a technical solution: an implantable infusion port detection device, including a base 9. One side of the base 9 is connected to a connecting plate 10, and the other side of the base 9 is connected to a column 11. A fixing hoop 12 is fixedly connected to the column 11. A chute 13 is formed on the column 11. A rack 14 is slidably connected to the column 11. One side of the rack 14 is connected to a connecting bar 28. The connecting bar 28 is integrally designed in a T shape and is connected to the cross arm 15. The connecting bar 28 is slidably connected to the chute 13. The rack 14 is engaged with a tooth block 27. By sliding the connecting bar 28 in the chute 13, the connecting bar 28 and the chute 13 can guide the movement of the rack 14, preventing the rack 14 and the cross arm 15 from skewing during movement.

[0034] One end of the rack 14 is connected to a cross arm 15. A liquid storage bottle 16 is installed above the cross arm 15. A pressure detector 17 is connected below the cross arm 15. A liquid pump 18 is installed above the cross arm 15. Two connecting pipes 19 are connected to the liquid pump 18. A pressure sensor 20 is electrically installed on the pressure detector 17. A communicating pipe 21 is connected to the pressure detector 17. One side of the liquid storage bottle 16 is connected to a liquid injection pipe 32. The liquid pump 18 is connected to the inside of the liquid storage bottle 16 through one connecting pipe 19, and the liquid pump 18 is connected to the communicating pipe 21 through the other connecting pipe 19.

By arranging the pressure sensor 20 between the connecting pipe 19 and the communicating pipe 21, the pressure sensor 20 can detect the hydraulic pressure of the physiological saline in real time, facilitating medical staff to detect and determine whether the physiological saline is flowing.

[0035] A threaded rod 22 is threadedly connected to the connecting plate 10. One end of the threaded rod 22 is connected to a handwheel 23, and the other end of the threaded rod 22 is rotatably connected to a clamping plate 24. A first anti-slip pad 29 is connected below the base 9, and a second anti-slip pad 30 is connected above the clamping plate 24. Two guide rods 31 are connected to the clamping plate 24. The two guide rods 31 are located on both sides of the threaded rod 22. The guide rods 31 are slidably connected to the connecting plate 10. During the process of the threaded rod 22 pulling the clamping plate 24 upward, the guide rods 31 will slide on the connecting plate 10, thereby restricting and guiding the clamping plate 24 through the two guide rods 31 to prevent the clamping plate 24 from rotating and skewing. Both the first anti-slip pad 29 and the second anti-slip pad 30 can increase the friction with the medical table, thereby preventing the base 9 from accidentally sliding.

[0036] A movable plate 25 is slidably connected to the fixing hoop 12. One side of the movable plate 25 is connected to a pulling plate 26, and the other side of the movable plate 25 is connected to a tooth block 27. A fixing rod 33 is connected to the fixing hoop 12. A snap plate 34 is rotatably connected to the pulling plate 26 through a pin shaft. Two sides of the snap plate 34 are connected to torsion springs 35. One end of the torsion spring 35 is connected to the pulling plate 26. An arc-shaped groove is provided on the snap plate 34 and is engaged with the fixing rod 33. Through the elastic rotation of the torsion spring 35, the snap plate 34 can be self-fastened on the fixing rod 33, so as to fix and limit the movable plate 25 through the snap plate 34 and prevent the movable plate 25 from accidentally sliding.

[0037] The using method of the implantable infusion port detection device includes the following steps:

[0038] By placing the base 9 on the medical staff's table, at this time, the medical staff can rotate the threaded rod 22 by turning the hand wheel 23, so as to prompt the threaded rod 22 to pull the clamping plate 24 to move upward, so that the clamping plate 24 can contact the edge of the table, so that the clamping plate 24 cooperates with the base 9 to clamp and fix the edge of the table, and fix the base 9 on the medical staff's table to prevent accidental sliding and falling damage. After that, the medical staff can rotate the snap plate 34 to disengage the snap plate 34 from the fixing rod 33;

[0039] Furthermore, the movable plate 25 is pulled by the pulling plate 26 to slide on the fixing hoop 12, so as to prompt the tooth block 27 to move away from the rack 14, so that the medical staff can push the cross arm 15 to make the connecting strip 28 and the rack 14 slide in the column 11 along the sliding groove 13. After that, by pushing the movable plate 25, the tooth block 27 and the rack 14 are engaged with each other, so as to fix the position of the rack 14 and prevent it from sliding down;

[0040] When the snap plate 34 is rotated, the torsion spring 35 will be twisted. Thus, after the tooth block 27 and the rack 14 are engaged, the snap plate 34 is released. Through the rotation of the torsion spring 35, the snap plate 34 is buckled on the fixing rod 33 through the arc-shaped groove on one side, so as to fix and limit the movable plate 25 and prevent the tooth block 27 from disengaging from the rack 14 due to accidental sliding. Furthermore, the height adjustment of the pressure detector 17 is completed to facilitate the medical staff's observation and use. After that, the medical staff connects an infusion pipeline to one end of the connecting pipe 21 and makes the injection needle body on the infusion pipeline pierce through the diaphragm 5 and extend into the liquid injection cavity 4;

[0041] After that, start the liquid pump 18, so that the liquid pump 18 extracts the physiological saline in the liquid storage bottle 16 through the connecting pipe 19 connected to the liquid storage bottle 16 and transports it to the connecting pipe 21 through another connecting pipe 19. At this time, the pressure sensor 20 will sense and detect the pressure of the physiological saline, and the physiological saline will be transported to the injection cavity 4 through the infusion pipeline and flow into the catheter 3 from the injection cavity 4. If the catheter 3 is blocked, at this time, the hydraulic pressure in the catheter 3, the connecting pipe 21 and the infusion pipeline will change, and will be detected by the pressure sensor 20 and transmitted to the pressure detector 17, so as to facilitate the staff to detect whether the catheter 3 is blocked to ensure the normal progress of the treatment.
