Description

Technical Field

[0001] This invention relates to the field of tumor chemotherapy technology, and in particular to a portable tumor chemotherapy device and its method of use. Background Technology

[0002] During chemotherapy for tumors, an infusion pump is used to slowly deliver medication to the patient, thereby producing a sufficient killing effect on tumor cells. Chemotherapy regimens are usually performed in cycles of 21, 14, or 28 days. Therefore, to facilitate patient movement, chemotherapy devices are typically designed as portable devices. Portable chemotherapy devices can usually provide continuous infusion for 44-48 hours. After each infusion, the next infusion is performed after an appropriate interval as prescribed by the doctor. The entire treatment course lasts 6-10 days. Therefore, multiple infusions are required throughout the entire treatment course. In addition, the needles need to be replaced during this process to avoid infection from prolonged use of the needles.

[0003] In the aforementioned prior art, portable tumor chemotherapy devices, due to their portability, may be used by patients outdoors or in areas where there is no garbage collection. In this case, once the needles are removed, the discarded needles are usually thrown away indiscriminately, polluting the surrounding environment. If the discarded needles are stored directly inside the portable tumor chemotherapy device, bacteria and odors will grow due to residual blood, tissue fluid, body fluid, or cell culture on the needles. Therefore, in the use of portable tumor chemotherapy devices, it is inconvenient to replace and dispose of the needles anytime and anywhere, affecting the user experience. Summary of the Invention

The rod spring 28, the support block 18 has a groove 29, the pressing and disassembly mechanism includes two limiting sliders 30, two limiting plates 31 and two locking blocks 32, the limiting plate 31 has a transverse groove 33 and a longitudinal groove 34, the needle replacement assembly also includes a needle cleaning unit, the needle cleaning unit includes a cleaning fixing chamber 36, a contact pad 37, an internal moving block 38, a linkage rod 39, a linkage rod spring 40, multiple rotating plates 41, multiple cleaning cotton 7 telescopic mechanisms, a sewage collection mechanism, an annular plate 42, two levers 43 and multiple telescopic stabilizing components, the cleaning cotton 7 telescopic mechanism includes a telescopic shell 45, multiple cleaning protrusions 46, a water storage tank 47, a water pump 48 and a telescopic hose 49, the sewage collection mechanism includes a sewage collection pump 50, a collection pipe 51 and a sewage tank 52, the cleaning fixing chamber 36 has multiple sewage outlets 53 and a sewage transfer trough 54.

[0033] The two shoulder straps 2 are located on one side of the portable housing 1, the control panel is located on the other side of the portable housing 1, the infusion pump 4 is located inside the portable housing 1, the infusion needle 5 is connected to the outlet end of the infusion pump 4, the cleaning rotating chamber 6 is located inside the portable housing 1, multiple cleaning cotton 7 are sequentially arranged inside the cleaning rotating chamber 6, multiple storage racks 8 are located on the inner top of the portable housing 1, and the quick-release unit is located on the infusion needle 5. The portable chemotherapy device can be carried by the patient using the shoulder strap 2. During use, the patient's skin is disinfected, and then the infusion needle 5 is inserted into the patient's blood vessel. The needle 5 is then secured with a 3M transparent dressing. The infusion control panel 3 is operated to start the infusion pump 4, which delivers the chemotherapy drug into the patient's body until one complete chemotherapy infusion is finished. The infusion needle 5 is then removed and inserted into the cleaning rotating chamber 6. The cleaning rotating chamber 6 rotates, and the cleaning cotton 7 cleans the infusion needle 5. The cleaned infusion needle 5 is then quickly removed using the quick-release unit and stored using the storage rack 8. After the patient has rested, a new infusion needle 5 is installed on the quick-release unit to begin the next round of continuous chemotherapy drug infusion.

[0034] Secondly, the two ends of the outlet pipe 9 are respectively connected to the infusion pump 4 and the outlet transfer tank 10. The outlet transfer tank 10 is located at one end of the portable housing 1. The two ends of the outlet telescopic pipe 11 are respectively connected to the outlet transfer tank 10 and the quick-release unit. The storage box slide rail 13 is located inside the portable housing 1. The temporary storage box 12 is slidably connected to the storage box slide rail 13. The liquid storage box 14 is placed on the inner bottom wall of the portable housing 1. The infusion pump 4 is connected to the liquid storage box 14. The storage support mechanism is located on the inner top of the portable housing 1. Multiple storage racks 8 are sequentially arranged on the storage support mechanism. The portable casing 1 also houses a battery pack to power various devices and ensure normal outdoor use. The temporary storage box 12 can store new infusion needles 5 for easy replacement. When needed, the temporary storage box 12 can be pulled out using the sliding rail 13. The storage support mechanism supports the storage rack 8. The tumor chemotherapy drug solution passes through the infusion pump 4 to the outlet tube 9, then enters the outlet transfer tank 10, and finally reaches the infusion needle 5 through the outlet telescopic tube 11. The outlet transfer tank 10 supports the outlet telescopic tube 11, which can freely extend and retract, facilitating flexible adjustment of the infusion needle 5. It also allows for easy access to the cleaning rotating chamber 6 from the side of the portable casing 1 for cleaning, and facilitates quick disassembly of the infusion needle 5 from above the portable casing 1.

[0035] Meanwhile, the storage groove 15 is disposed on the inner top wall of the portable housing 1, and multiple storage racks 8 are slidably connected to the storage groove 15. One end of the sliding lever 16 is fixedly connected to the storage rack 8, and the other end of the sliding lever 16 is slidably connected to the portable housing 1. Multiple disassembly posts 17 are sequentially disposed above the corresponding storage racks 8. When disassembly is required, the sliding lever 16 is first moved to slide, causing the storage rack 8 to slide on the storage groove 15, thereby moving the free storage rack 8 to below the infusion needle 5. At this time, the infusion needle 5 is inserted from above the portable housing 1 and then placed on the storage rack 8. Simultaneously, the disassembly post 17 activates the quick-release unit, thereby quickly disassembling the infusion needle 5.

[0036] In addition, the support block 18 is fixedly connected to the end of the liquid outlet telescopic tube 11 away from the liquid outlet transfer tank 10. The disassembly block 19 is located on one side of the support block 18. The disassembly block 19 has two through holes 22, both of which are adapted to the limiting post 20 and the auxiliary post 21. The infusion needle 5 is connected to the liquid outlet telescopic tube 11. The rotation unlocking mechanism is located on one side of the support block 18, and the pressing disassembly mechanism is located on the rotation unlocking mechanism. The disassembly block 19 is made of metal, and the upper surface of the storage rack 8 is made of magnets. Therefore, after the disassembly block 19 is placed on the storage rack 8, the shaking and falling off can be reduced, making it convenient for patients to carry outdoors. When the infusion needle 5 needs to be quickly disassembled, the limiting post 20 is first released by the rotating unlocking mechanism. At this time, the infusion needle 5 is pressed down, so that the limiting post 20 and the disassembly post 17 abut against each other, activating the pressing disassembly mechanism. Then, the disassembly post 17 pushes the limiting post 20 to retract, and the limiting post 20 enters the groove 29 and disengages from the through hole 22. At the same time, the limiting post 20 is no longer limited, and the auxiliary post 21 used for auxiliary stabilization on the other side is also pushed out of the through hole 22, thereby completing the quick disassembly of the infusion needle 5.

[0037] Then, the support block 18 has a groove 29, the rotating cylinder 26 is located inside the groove 29, the telescopic rod 27 is slidably connected to the rotating cylinder 26, the two ends of the telescopic rod spring 28 are movably connected to the inner walls of the telescopic rod 27 and the rotating cylinder 26 respectively, one end of the rotating shaft 24 passes through the support block 18 and is fixedly connected to the rotating cylinder 26, the other end of the rotating shaft 24 is fixedly connected to the rotating block 23, and the torsion spring 25 is disposed between the support block 18 and the rotating block 23. When the limiting post 20 is in contact with the telescopic limit, the rotating block 23 is first rotated, which drives the rotating shaft 24 to rotate, causing the rotating cylinder 26 to rotate, which in turn drives the telescopic rod 27 to rotate, thereby activating the pressing and disassembly mechanism and releasing the limiting post 20. At this time, the infusion needle 5 is pressed down, causing the disassembly post 17 to push the limiting post 20 to retract. After use, the telescopic rod spring 28 first drives the telescopic rod 27 to rebound, causing the limiting post 20 to reset. At this time, the rotating block 23 is released, and the torsion spring 25 drives the rotating block 23, the rotating shaft 24, the rotating cylinder 26 and the telescopic rod 27 to reset, so as to re-limit the limiting post 20.

[0038] Furthermore, the limiting plate 31 has a transverse groove 33 and a longitudinal groove 34, which are connected. The two limiting plates 31 are symmetrically arranged inside the groove 29. The two limiting sliders 30 are symmetrically arranged outside the telescopic rod 27. The other ends of the two limiting sliders 30 are respectively located inside the corresponding transverse groove 33. The other ends of the limiting sliders 30 are adapted to the transverse groove 33 and the longitudinal groove 34. The two locking blocks 32 are symmetrically arranged outside the limiting post 20. The disassembly block 19 has two slots 35, and the locking blocks 32 are adapted to the slots 35. When the telescopic rod 27 rotates, it drives the limiting slider 30 to slide in the transverse groove 33 of the limiting plate 31. After sliding to the end, it is exactly on the trajectory of the longitudinal groove 34, so that the telescopic rod 27 can move longitudinally (i.e., extend and retract). Since the telescopic rod 27 is connected to the limiting post 20, the rotation of the telescopic rod 27 has already driven the limiting post 20 to rotate, so that the locking blocks 32 on both sides of the limiting post 20 move to the corresponding slots 35. At this time, the limiting post 20 is not limited by the locking blocks 32 and the limiting slider 30, so it can extend and retract, and finally disengage from the through hole 22 to complete the quick release. In addition, when installing and connecting the support block 18 and the disassembly block 19, it is also necessary to first rotate the rotating block 23 to drive the limiting post 20 to rotate, so that the locking blocks 32 on both sides correspond to the slots 35, so that the limiting post 20 can be smoothly inserted into the through hole 22.

[0039] Furthermore, the needle cleaning unit is disposed inside the portable housing 1; the cleaning fixing chamber 36 is disposed inside the portable housing; the cleaning rotating chamber 6 is rotatably connected to one end of the cleaning fixing chamber 36; the linkage rod 39 is slidably connected to the interior of the cleaning fixing chamber 36; the internal moving block 38 is disposed at one end of the linkage rod 39; the contact point is disposed at one end of the internal moving block 38; the other end of the linkage rod 39 is rotatably connected to one end of a plurality of rotating plates 41; and the two ends of the linkage rod spring 40 are respectively connected to the internal moving block 38 and the cleaning fixing chamber 36. The inner wall is movably connected, and multiple cleaning cotton 7 telescopic mechanisms are sequentially arranged inside the cleaning rotating chamber 6. The cleaning cotton 7 is arranged on the cleaning cotton 7 telescopic mechanism. The sewage collection mechanism is arranged on one side of the cleaning fixed chamber 36. The annular plate 42 is rotatably connected to the inner side wall of the portable shell 1. Both ends of each telescopic stabilizing component are respectively connected to the annular plate 42 and the corresponding cleaning cotton 7 telescopic mechanism. The portable shell 1 has two arc-shaped grooves 44. One end of each of the two levers 43 is fixedly connected to the annular plate 42, and the levers 43 are slidably connected to the arc-shaped grooves 44.The cleaning fixing chamber 36 supports the cleaning rotating chamber 6. During cleaning, the infusion needle 5 is first brought into contact with the contact pad 37 to prevent damage. Then, the infusion needle 5 is pressed into the cleaning rotating chamber 6. The contact pad 37 drives the internal moving block 38 to move, causing the linkage rod 39 to move, which in turn drives the rotating plate 41 to move. The rotating plate 41 drives the telescopic mechanism of the cleaning cotton 7 to move, so that the cleaning cotton 7 contacts the outer wall of the infusion needle 5. At this time, the cleaning rotating chamber 6 rotates to perform the cleaning operation. The wastewater generated during cleaning is collected by the wastewater collection mechanism. Thus, after the infusion needle 5 is inserted into the cleaning rotating chamber 6, the cleaning cotton 7 can quickly contact it and rotate to complete the cleaning. The operation is smooth and simple, without too many cumbersome operations, significantly improving cleaning efficiency. This allows for quick cleaning and disassembly and storage of the used infusion needle 5 when used outdoors. To improve convenience, the rotating cleaning chamber 6 rotates, causing the annular plate 42 to rotate as well, maintaining stability. Simultaneously, by moving the lever 43, it slides in the arc-shaped groove 44, and through the connection between the annular plate 42 and the telescopic stabilizing component, the rotating cleaning chamber 6 rotates, allowing the cleaning cotton 7 to rub against the infusion needle 5 for cleaning. When the cleaning cotton 7 telescopic mechanism extends or retracts, the telescopic stabilizing component extends or retracts accordingly, maintaining stability. The telescopic stabilizing component consists of a spring and a telescopic rod. Furthermore, the telescopic stabilizing component can also cause the cleaning cotton 7 telescopic mechanism to spring back, so that the cleaning cotton 7 can spring back after the infusion needle 5 leaves the rotating cleaning chamber 6. Additionally, the portable outer shell 1 is equipped with a bolt-fixed back plate; removing the back plate facilitates disassembly and maintenance of the internal components.

[0040] Thus, the telescopic shell 45 is slidably connected to the cleaning rotating chamber 6, the cleaning cotton 7 is disposed at one end of the telescopic shell 45 and located inside the cleaning rotating chamber 6, a plurality of cleaning protrusions 46 are sequentially disposed on one side of the cleaning cotton 7, the water storage tank 47 is disposed outside the cleaning fixed chamber 36, the water pump 48 is connected to one side of the water storage tank 47, one end of the telescopic hose 49 is connected to the water pump 48, and the other end of the telescopic hose 49 passes through the telescopic shell 45 and contacts the cleaning cotton 7. When the rotating plate 41 moves, it contacts the inclined surface of the telescopic shell 45, thereby causing the telescopic shell 45 to extend and retract. Finally, the cleaning cotton 7 contacts the infusion needle 5. At this time, the lever 43 can slide in the arc groove 44 to perform cleaning. In addition, the cleaning protrusion 46 can improve the cleaning effect. During cleaning, the water pump 48 can be started to extract the cleaning liquid in the water tank 47 and deliver it to the cleaning cotton 7 through the telescopic hose 49. After the cleaning cotton 7 absorbs the cleaning liquid, the cleaning effect is enhanced. In addition, due to the setting of the telescopic hose 49, the telescopic hose 49 can extend and retract with the rotating cleaning chamber 6 when it rotates without being obstructed. At the same time, the rotating plate 41 also rotates on the linkage rod 39, thereby avoiding the rotating plate 41 being unable to rotate, which would hinder the rotation and cleaning of the cleaning cotton 7.

[0041] Finally, the cleaning fixed chamber 36 has multiple sewage outlets 53 and a sewage transfer trough 54. The sewage collection pump 50 is located on one side of the cleaning fixed chamber 36. All the sewage outlets 53 are connected to the sewage transfer trough 54. The inlet of the sewage collection pump 50 is connected to the sewage transfer trough 54. The collection pipe 51 is connected to the outlet of the sewage collection pump 50. The sewage tank 52 is located below the collection pipe 51 and is connected to the collection pipe 51.
