Description

Technical Field

[0001] The invention relates to the technical field of thermal perfusion instruments and equipment, in particular to a perfusion pipeline collecting and diverting regulating disk. Background Art

[0002] Hyperthermia chemotherapy is a new therapy that combines chemotherapy and hyperthermia to treat tumors. Its principle is to use physical energy to heat chemotherapy drugs with good thermal effects, infuse them into the human body cavity, so that the temperature of the tumor tissue rises to an effective treatment temperature and maintains it for a certain period of time. By taking advantage of the difference in temperature tolerance between normal tissues and tumor cells, the therapeutic purpose of causing tumor cell apoptosis without damaging normal tissues can be achieved.

[0003] When using a hot perfusion instrument, multiple perfusion hoses need to be installed. Medical staff often need to switch the conduction of the hoses back and forth according to the treatment situation to allow the perfusion liquid to circulate in different circuits. For example, during preheating, the perfusion liquid needs to circulate in the extracorporeal tubes; during hot perfusion flushing treatment, the perfusion liquid needs to circulate in the internal tubes. The switching of the two circulation modes needs to be regulated by opening and closing the switches on the hoses (such as water stop clamps), but the existing multiple switches are independent of each other and cannot be controlled synchronously. Moreover, the existing perfusion hoses are relatively long, crisscrossed together, and scattered beside the bed. If the perfusion hoses are accidentally pulled during treatment, it will cause pain to the patient, which further leads to the difficulty of operating the switches. Summary of the Invention

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 7 As shown, the adjustment disk body 1 is disassembled and connected to one side of the hot perfusion chemotherapy device 28, and the adjustment disk body 1 is vertically arranged to the side of the hot perfusion chemotherapy device 28, so as to facilitate the insertion of the hose 29 connected to the hot perfusion chemotherapy device 28 into the adjustment disk.

[0030] like Figure 1 As shown, four flow regulating devices and four line gathering devices are fixedly installed inside the regulating disk body 1. The flow regulating devices and line gathering devices surround the regulating disk body 1 and are arranged alternately.

[0031] Specifically, four hoses 29 are required for hot perfusion therapy. Each hose 29 passes through a flow regulating device and a line collection device. Every two hoses 29 form a loop. The two loops are a loop passing through the human body cavity (internal circulation loop) and a loop outside the human body cavity (external circulation loop). In this way, the two hoses 29 in each loop can be clamped to stop the flow and the pipelines can be collected separately.

[0032] refer to Figure 6 , Figure 6 The hose 29 indicated by the dotted line represents the inner circulation loop, the hose 29 indicated by the solid line represents the outer circulation loop, A represents the outlet pipe on the hot perfusion chemotherapy apparatus, and B represents the return pipe on the hot perfusion chemotherapy apparatus, wherein the outlet pipe is connected to the peristaltic pump;

[0033] Two hoses 29 in the internal circulation loop, one of which is connected to the outlet pipe A of the hot perfusion chemotherapy device 28 at one end near its flow regulating device, and the other hose 29 is connected to the return pipe B of the hot perfusion chemotherapy device 28 at one end near its flow regulating device. The ends of the two hoses 29 near their respective line collection devices are respectively connected to the inlet catheter 30;

[0034] There are two hoses 29 in the external circulation loop, one of which is connected to the outlet pipe A of the hot perfusion chemotherapy device 28 at one end near its flow regulating device, and the other hose 29 is connected to the return pipe B of the hot perfusion chemotherapy device 28 at one end near its flow regulating device. The two hoses 29 are connected in series to a medical filter 31 at one end near their respective line collection devices.

[0035] Further, as Figure 3 As shown, a support plate 12 is installed in the upper port of the above-mentioned regulating disk main body 1, and the lower end of the support plate 12 is fixedly connected to the inside of the regulating disk main body 1 through a plurality of vertical plates. Four grooves 13 are provided on the outside of the support plate 12, and each groove 13 corresponds to a flow regulating device and a line collection device. Four notches 14 and four slots 15 are provided on the outer edge of the above-mentioned regulating disk main body 1, and the four notches 14 correspond one-to-one to the four flow regulating devices, and the four slots 15 correspond one-to-one to the four line collection devices.

[0036] like Figure 2 As shown, two movable disks 2 are coaxially arranged in the regulating disk body 1, and two push rods 3 are hinged on the same diameter line on the outside of the movable disk 2, and one push rod 3 controls a flow regulating device. The plane where the two push rods 3 on the upper movable disk 201 is located is perpendicular to the plane where the two push rods 3 on the lower movable disk 202 are located. The two movable disks 2 are coaxially threaded with threaded rods 4, and the threads on the threaded rods 4 acting on the two movable disks 2 turn in opposite directions. One movable disk 2 controls the action of the two flow regulating devices in the lower inner circulation loop, and the other movable disk 2 controls the action of the two flow regulating devices in the outer circulation loop. Under the control of the same threaded rod 4, the two movable disks 2 move synchronously. When the two movable disks 2 are close, the two hoses 29 in the inner circulation loop are clamped to stop the flow, and the two hoses 29 in the outer circulation loop are both connected. When the two movable disks 2 are away from each other, the two hoses 29 in the inner circulation loop are both connected, and the two hoses 29 in the outer circulation loop are clamped to stop the flow, thereby realizing automatic switching between internal and external circulation.

[0037] like Figure 3 As shown, the flow regulating device includes an outer support seat 5 and an inner support seat 6 fixedly connected to the bottom of the regulating disk body 1, an outer clamping wheel 7 is slidably connected to the outer support seat 5, and an inner clamping wheel 8 is slidably connected to the inner support seat 6. The clamping wheels are composed of a plastic bracket and a plastic roller. The opening and closing of the two clamping wheels realize the opening and closing of the hose 29; the outer clamping wheel 7 and the inner clamping wheel 8 are kept in linkage through a hinged connecting rod assembly, and the lower end of the inner clamping wheel 8 is provided with a sliding member slidably connected to the bottom of the regulating disk body 1;

[0038] The sliding member in each of the above flow regulating devices is hinged to the push rod 3 on the corresponding side;

[0039] Furthermore, if Figure 3 As shown, the above-mentioned hinged link assembly includes a vertical rod 16, a middle link 17 and two end links 18. The vertical rod 16 is fixedly connected to the bottom of the adjusting disk body 1. The length of the vertical rod 16 is equal to that of the two support seats. The middle section of the middle link 17 is rotatably connected to the upper end of the vertical rod 16. The two ends of the middle link 17 are respectively hinged with end links 18. Among them, the free end of one end link 18 is hinged to the outer clamping wheel 7, and the free end of the other end link 18 is hinged to the inner clamping wheel 8, so that the two clamping wheels move synchronously. In this way, the opening and closing of the two clamping wheels can be controlled by controlling the inner clamping wheel 8. Tension springs 26 are respectively provided between the above-mentioned outer clamping wheel 7 and the outer support seat 5 and between the inner clamping wheel 8 and the inner support seat 6. The two tension springs 26 can assist in pulling the two clamping wheels apart, making the opening and closing of the two clamping wheels smoother.

[0040] Furthermore, if Figure 3 As shown, the above-mentioned sliding parts include a slide plate 19, a slide rail 20 and a multi-section connecting rod 21. The slide rail 20 is fixedly connected to the bottom of the adjusting disk main body 1 along the radial direction of the adjusting disk main body 1, and the slide plate 19 is slidably clamped on the slide rail 20. The end of the slide plate 19 away from the movable disk 2 is fixedly connected to the inner clamping wheel 8 through the connecting rod 21. The end of the slide plate 19 close to the movable disk 2 is hinged to the push rod 3 on the corresponding side. Among the four slide plates 19, the height of the slider hinged to the push rod 3 on the upper movable disk 201 is greater than the height of the slider hinged to the push rod 3 on the lower movable disk 202. With this arrangement, the push rod 3 on the upper movable disk 201 will not interfere with the lower movable disk 202 when it moves.

[0041] Specifically, the downward movement of the movable plate 2 can press down one end of the push rod 3, so that the other end of the push rod 3 pushes the slider to move outward along the slide rail 20, thereby pushing the inner clamping wheel 8 outward. Under the action of the above-mentioned hinged connecting rod assembly, the outer clamping wheel 7 moves inward, and the two clamping wheels approach each other to clamp the hose 29 to stop the flow. Similarly, when the movable plate 2 moves upward, the two clamping wheels move away from each other, disengaging from the clamping of the hose 29, and the liquid in the hose 29 flows.

[0042] Further, if Figure 3 and Figure 4 As shown, the flow regulating device is further provided with an auxiliary pushing device, which includes a fixed block 22 and a movable block 23. The fixed block 22 is fixedly connected to one end of the outer support seat 5 close to the inner support seat 6, and the movable block 23 is fixedly connected to a connecting seat 24 on the side away from the support seat. Two auxiliary connecting rods 25 of equal length are hinged on the connecting seat 24, wherein the free end of one auxiliary connecting rod 25 is hinged on the outer clamping wheel 7, and the free end of the other auxiliary connecting rod 25 is hinged on the inner clamping wheel 8. The movable block 23 is made of rubber. A gap is left between the fixed block 22 and the inner support seat 6. The hose 29 passes through the gap and enters between the two support seats. The auxiliary pushing device can help the squeezed hose 29 to recover.

[0043] Specifically, after the hose 29 is clamped and flow-stopped by the two clamping wheels, even if the two clamping wheels have been released from the squeezing effect on the hose 29, the squeezed part of the hose 29 sometimes cannot be quickly restored, which can easily cause pipe blockage during infusion; the movable block 23 in the auxiliary pushing device can move with the movement of the two clamping wheels. When the two clamping wheels move away from each other, the movable block 23 approaches the fixed block 22, thereby giving the deflated hose 29 an auxiliary pushing effect, helping the squeezed part of the hose 29 to restore to a round shape, and the minimum distance between the movable block 23 and the fixed block 22 is greater than the diameter of the hose 29, and the movable block 23 will not further squeeze the hose 29. In addition, when the two clamping wheels approach each other, the movable block 23 is away from the fixed block 22, which will not affect the clamping and flow-stopping of the hose 29 by the two clamping wheels.

[0044] like Figure 5 As shown, the above-mentioned line collection device includes a positioning disk 9 and a pipe collecting disk 10. The positioning disk 9 is fixedly connected to the bottom of the adjusting disk body 1. The pipe collecting disk 10 is coaxially fixedly connected to the positioning disk 9. A pipe collecting rack 11 for winding the hose 29 is provided on the outside of the pipe collecting disk 10. The above-mentioned pipe collecting rack 11 includes a plurality of bent rods arrayed along the circumference of the pipe collecting disk 10. The bent rods are used to block the hose 29 wound around the outside thereof. One line collection device corresponds to one flow regulating device, so that each hose 29 can be reasonably wound on the pipe collecting rack 11. This winding method is relatively loose and will not cause blockage to the hose 29.

[0045] Furthermore, a turning handle 27 is installed on the upper end of the threaded rod 4, and the turning handle 27 is located outside the support plate 12. By manipulating the turning handle 27 to control the rotation of the threaded rod 4, the switching flow of the perfusion liquid in the external circulation pipe and the internal circulation pipe is realized.

[0046] Furthermore, the upper surface of the support plate 12 is provided with two rotation marks located on the outside of the threaded rod 4, wherein the clockwise rotation mark represents extracorporeal circulation, that is, when the threaded rod 4 rotates clockwise, the hose 29 in the internal circulation loop is clamped to stop the flow, the hose 29 in the external circulation loop flows, and the perfusion liquid circulates in the external circulation loop; the counterclockwise rotation mark represents intracorporeal circulation, that is, when the threaded rod 4 rotates counterclockwise, the hose 29 in the external circulation loop is clamped to stop the flow, the hose 29 in the internal circulation loop flows, and the perfusion liquid circulates through the human abdominal cavity for hot perfusion treatment.

[0047] The working principle of the perfusion pipeline collection and diversion regulating disk of this embodiment is described in detail below:

[0048] First, the medical staff plugs the four hoses 29 into the flow regulating device and the line collection device respectively. Here, the threading method of one of the hoses 29 is introduced as an example. The hose 29 passes through the notch 14 corresponding to a flow regulating device, passes between the two clamping wheels in the flow regulating device, then goes around the back side of the tube receiving disk 10 in a line collection device, and then extends out from the corresponding slot 15 of the line collection device. At this time, the hose 29 has not been wound around the tube receiving disk 10 and has not been clamped. The hose 29 can be stretched at will to adjust the length of the two ends of the hose 29 from the regulating disk respectively. Since the hose 29 is located at one end of the flow regulating device and is connected to the hot perfusion chemotherapy device 28, the length of the hose 29 extending in the direction of the flow regulating device is moderate, and the length of the hose 29 extending in the direction of the line collection device is longer; after the four hoses 29 are installed, a set of internal circulation loop and external circulation loop are formed, the two inlet catheters 30 on the internal circulation loop are respectively inserted into the human abdominal cavity, and a medical filter 31 is connected in series to the external circulation loop;

[0049] After the hoses 29 are arranged, the longer hoses 29 are wound on the hose collection rack 11. The multiple bends can prevent the hoses 29 from falling out, thereby arranging the hoses 29 and collecting the messy hoses 29 next to the bed.

[0050] During hyperthermic perfusion therapy, extracorporeal circulation is required to preheat the entire perfusion fluid, that is, extracorporeal circulation is required first, followed by intracavitary circulation;

[0051] When extracorporeal circulation is performed, the threaded rod 4 is rotated clockwise, the upper movable plate 201 moves upward, and one end of the push rod 3 connected to the upper movable plate 201 moves upward. Under the cooperation of the tension spring 26, the inner clamping wheel 8 and the slider move along the radial axis of the adjusting plate body 1, and the two clamping wheels open, so that the hose 29 in the external circulation loop is conductive, and when opened, the movable block 23 and the fixed block 22 in the auxiliary pushing device slightly push the deflated hose 29 to help the recovery of the squeezed part of the hose 29. At the same time, the lower movable plate 202 also moves downward, and one end of the push rod 3 connected to the lower movable plate 202 moves downward. The other end of the push rod 3 pushes the slider to move outward along the slide rail 20, and the two clamping wheels approach to clamp the hose 29 in the internal circulation loop to stop the flow. At this time, after the peristaltic pump is turned on, the perfusion liquid circulates through the external circulation loop, and the heating body continues to heat the perfusion liquid until the temperature stabilizes for internal circulation;

[0052] When performing intracavitary circulation, the threaded rod 4 is rotated counterclockwise, similar to the above operation, so that the hose 29 in the external circulation loop is clamped to stop the flow, and the hose 29 in the internal circulation loop is connected. Under the action of the peristaltic pump, the perfusion liquid circulates in the hose 29 of the internal circulation loop and circulates in the human abdominal cavity through the two inlet catheters 30, thereby realizing hot perfusion and flushing treatment of the abdominal cavity.

[0053] The present invention cooperates with the outer clamping wheel and the inner clamping wheel, the upper movable plate and the lower movable plate, and the pushing rod, and utilizes the forward or reverse rotation of the threaded rod to clamp different hoses to stop the flow, thereby realizing automatic switching of the perfusion liquid between the inner circulation loop and the outer circulation loop, and the opening and closing of the two loops are carried out simultaneously to prevent accidents; through the arrangement of the tube collecting disc and the tube collecting rack, one tube collecting disc corresponds to a flow regulating device, which can wrap the hose around the tube collecting rack, thereby playing a role in reasonably collecting longer hoses and avoiding the phenomenon that the hoses are messy and cause difficulties in monitoring during perfusion; through the cooperative arrangement of the hinged connecting rod assembly, the sliding part and the tension spring, the outer clamping wheel and the inner clamping wheel can be made to slide synchronously, and the stability of the two clamping wheels during operation is guaranteed; through the arrangement of the auxiliary pushing device, the movable block moves synchronously with the opening and closing of the two clamping wheels, repairs the squeezed part on the hose, helps the hose to recover, and ensures the normal conduction of the hose.

[0054] It can be seen that the use of the perfusion pipe collection and diversion adjustment disk provided by the present invention can effectively solve the problems of unchanged circulation loop switching in the hot perfusion therapy device and the messy perfusion hose interfering with monitoring.
