Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of drug perfusion equipment, and in particular to a drug perfusion equipment for tumor interventional treatment and a use method thereof. Background Art
[0002] Tumor interventional therapy refers to a minimally invasive treatment method that uses imaging techniques such as X-ray, CT, ultrasound, and MRI to accurately focus radiofrequency, microwaves, ultrasound, or chemical substances on the lesion site to kill tumor cells and thus achieve the purpose of treating tumors. Clinically, tumor interventional therapy is divided into vascular interventional therapy and non-vascular interventional therapy. Interventional therapy has the characteristics of no surgery, less trauma, quick recovery, and good effect. It is the development trend of future medicine.
[0003] During interventional treatment of tumors, the puncture needle must first be inserted into the designated area. After the puncture is successful, a guide wire is introduced through the puncture needle, and then the catheter is inserted into the blood vessel along the guide wire. After that, it reaches the designated place under the guidance of the guide wire, and then the drug is delivered to the place that needs treatment through the catheter. Generally, existing devices directly maintain the sealing of the connection between the needle and the catheter by the medical staff holding the needle to prevent leakage. However, this method requires medical staff to maintain the same action for a long time. At this time, the medical staff is prone to hand fatigue, which may result in the connection between the needle and the catheter not being able to achieve a good sealing effect. During the perfusion process, external bacteria and other microorganisms may enter the body due to failure to be completely sealed, thereby affecting the surgical effect. Summary of the invention

[0015] Furthermore, a method for using a drug perfusion device for tumor interventional treatment, the drug perfusion device for tumor interventional treatment, the method comprising the following steps:
[0016] S1: First, the medical staff uses sterile tools to connect the tube containing the medicine between the connection port and the airbag, then connects the tube to be perfused to the bottom of the connection port, and then starts the external perfusion device to allow the medicine to flow into the connection port along the tube;
[0017] S2: When the drug passes through the connection port, it will be transported into the patient's body along the connecting pipe at the bottom of the connection port to complete the perfusion work.
[0018] The present invention has the following beneficial effects:
[0019] (1) In the present invention, when the medicine flows into the interior of the connecting port along the pipeline, when the medicine flows to the top of several fan blades, the fan blades will be subjected to the impact force generated by the flow of the medicine. Under the action of the impact force, the fan blades will rotate. When the fan blades rotate, they will drive the grille ring to rotate together. When the grille ring rotates, the medicine liquid flows along the inner wall to the interior of the airbag. At the same time, the airbag will expand outward due to the continuous entry of the medicine liquid. When the airbag expands, the distance between the airbag and the connecting port will become smaller and smaller, thereby achieving a sealing effect. When the device is about to finish infusing, part of the medicine liquid in the airbag will flow out from several trapezoidal grooves opened on the connecting port. When the medicine liquid flows out of the trapezoidal grooves, part of the medicine liquid will flow to the top of the fan blades, thereby further promoting the rotation of the fan blades. The device plays a sealing role while infusing the medicine, reducing the possibility of external microorganisms such as bacteria, fungi, viruses, etc. entering the medicine.
[0020] (2) According to the present invention, when the fan blades rotate, the gear plate 1 and the gear plate 2 will be driven to rotate together, and at the same time, the limit plate will limit the cylinder. When the gear plate 1 and the gear plate 2 rotate, the rotating column 1 will be caused to rotate back and forth. When the rotating column 1 rotates, the square limit plate 1 rotatably connected to its outer surface will limit the rotating column. When the rotating column 1 rotates back and forth, it will drive the rotating column 2 to rotate back and forth. When the rotating column 2 rotates, the square limit plate 2 rotatably connected to its outer surface will limit the rotating column 2. When the rotating column 2 rotates, one of the rotating blocks will be driven to rotate back and forth through the rotating plate 1. When the rotating block fixedly connected to the rotating plate 1 rotates back and forth, it will drive The remaining rotating blocks are driven to rotate back and forth together. When several rotating blocks rotate back and forth together, the rotating frame will drive the circular plate to produce an opening and closing effect. When the drug stops flowing in, the fan blades will also stop rotating, thereby stopping the opening and closing of the circular plate. When the circular plate stops opening and closing, the springs fixedly connected between the rotating blocks will make the rotating blocks return to the starting position. When the rotating blocks return to the starting position, the circular plate will be closed, thereby preventing the drug from flowing back, reducing the possibility that highly irritating drugs such as chemotherapy drugs may seep into the tissues around the blood vessels due to drug reflux, and reducing harm to the human body. The device can effectively reduce this risk by preventing drug reflux and ensure the normal flow of drugs in the blood vessels.
[0021] (3) In the present invention, when the infusion is about to end, the medicine inside the airbag will flow out from the hole opened at the bottom due to gravity. When the medicine flows out of the airbag, it will generate an impact force on the side of the rotating plate 2 close to the airbag. When the rotating plate 2 is impacted, it will rotate accordingly. When the rotating plate 2 rotates, it will drive the spring block to rotate together, thereby enhancing the rotation efficiency. When the rotating plate 2 rotates, it will drive the crank rod to rotate. When the crank rod rotates, it will drive the disc to swing up and down through the flexible rod. When the disc swings up and down, it will squeeze the bottom of the airbag, thereby making the medicine inside the airbag flow out better. Generally, the existing device does not apply an external force to the outside of the airbag when working. At this time, it is difficult for the medicine inside the airbag to flow out completely, thereby failing to ensure complete infusion of the medicine. The device is provided with an extrusion device at the bottom of the airbag, which can generate an external force to push the airbag, thereby reducing the waste caused by drug residues, and at the same time increasing the possibility that the patient receives a relatively complete therapeutic dose, thereby improving the therapeutic effect.

[0046] A method for using a drug perfusion device for tumor interventional treatment, the drug perfusion device for tumor interventional treatment, the method comprising the following steps:
[0047] S1: First, the medical staff uses a sterile tool to connect the pipe containing the medicine between the connection port 102 and the airbag 206, and then connects the pipe to be perfused to the bottom of the connection port 102, and then starts the external perfusion device to make the medicine flow into the connection port 102 along the pipe;
[0048] S2: After the medicine passes through the connection port 102, it will be transported into the patient's body along the connection pipe at the bottom of the connection port 102, completing the perfusion work.
[0049] When in use, the medical staff first uses a sterile tool to place the pipe containing the medicine between the connecting port 102 and the airbag 206, and then starts the device containing the medicine. The medicine then flows into the connecting port 102 along the pipe. When the medicine flows to the top of the plurality of blades 201, the blades 201 will be subjected to the impact force generated by the flow of the medicine. Under the action of the impact force, the blades 201 will rotate. When the blades 201 rotate, the grille ring 203 will rotate together. When the grille ring 203 rotates, the liquid medicine flows along the inner wall to the inside of the airbag 206. At the same time, the airbag 206 will be affected by the liquid medicine. It continues to enter and expand outward. When the airbag 206 expands, the distance between the airbag 206 and the connecting port 102 will become smaller and smaller, thereby achieving a sealing effect. When the device is about to finish infusing, part of the medicine in the airbag 206 will flow out from a plurality of trapezoidal grooves opened on the connecting port 102. When the medicine flows out of the trapezoidal grooves, part of the medicine will flow to the top of the fan blade 201, thereby further promoting the rotation of the fan blade 201. The device plays a sealing role while infusing the medicine, reducing the possibility of external microorganisms such as bacteria, fungi, viruses, etc. entering the medicine.
[0050] When the fan blade 201 rotates, it will drive the gear plate 1 204 and the gear plate 205 to rotate together. At the same time, the limit plate 202 will limit the cylinder. When the gear plate 1 204 and the gear plate 205 rotate, the rotating column 1 301 will rotate back and forth. When the rotating column 1 301 rotates, the square limit plate 1 rotatably connected to its outer surface will limit the rotating column 1 301. When the rotating column 1 301 rotates back and forth, it will drive the rotating column 2 302 to rotate back and forth. When the rotating column 2 302 rotates, the square limit plate 2 rotatably connected to its outer surface will limit the rotating column 2 302. When the rotating column 2 302 rotates, one of the rotating blocks 304 will be driven to rotate back and forth through the rotating plate 1 303. When the rotating block 304 fixedly connected to the rotating plate 1 303 is rotated, When the rotating blocks 304 rotate back and forth, they will drive the other rotating blocks 304 to rotate back and forth together. When several rotating blocks 304 rotate back and forth together, they will drive the circular plate 306 to produce an opening and closing effect through the rotating frame 305. When the medicine stops flowing in, the fan blades 201 will also stop rotating, so that the circular plate 306 stops opening and closing. When the circular plate 306 stops opening and closing, the springs fixedly connected between the rotating blocks 304 will make the rotating blocks 304 return to the starting position. When the rotating blocks 304 return to the starting position, the circular plate 306 will be closed, thereby preventing the medicine from flowing back, reducing the possibility that highly irritating drugs such as chemotherapy drugs may seep into the tissues around the blood vessels due to drug reflux, and reducing the harm to the human body. The device can effectively reduce this risk by preventing drug reflux and ensure the normal flow of drugs in the blood vessels.
[0051] When the infusion is about to end, the medicine inside the airbag 206 will flow out from the hole at the bottom due to gravity. When the medicine flows out of the airbag 206, it will generate an impact force on the side of the rotating plate 203 close to the airbag 206. When the rotating plate 203 is impacted, it will rotate accordingly. When the rotating plate 203 rotates, it will drive the spring block 404 to rotate together, thereby enhancing the efficiency of the rotation. When the rotating plate 203 rotates, it will drive the crank rod 402 to rotate. When the crank rod 402 rotates, it will drive the disk 406 to swing up and down through the flexible rod 405. When the disk 406 is rotated, the spring block 404 will rotate together. When the disk 406 swings up and down, it squeezes the bottom of the airbag 206, so that the medicine inside the airbag 206 can flow out better. Generally, the existing device does not apply an external force to the outside of the airbag 206 when working. At this time, it is difficult for the medicine inside the airbag 206 to flow out completely, and thus it is impossible to ensure complete infusion of the medicine. The device is provided with a squeezing device at the bottom of the airbag 206, which can generate an external force to push the airbag 206, thereby reducing the waste caused by drug residues, and at the same time increasing the possibility that the patient receives a relatively complete therapeutic dose, thereby improving the treatment effect.
