Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for preparing infusion chemotherapy drugs in the field of oncology. Background Technology

[0002] Arterial infusion chemotherapy, as a minimally invasive, safe, and less painful cancer treatment, boasts advantages such as being non-surgical, minimally traumatic, allowing for rapid patient recovery, and exhibiting significant therapeutic effects. In practice, this technique skillfully combines multiple highly effective anticancer drugs, using advanced catheter technology to precisely locate the tumor's feeding artery and directly inject the anticancer drugs into the tumor tissue, achieving precise targeting of the tumor.

[0003] Patent publication number CN117205825A discloses a chemotherapy perfusion dispensing device for oncology. It involves adding pre-stored drugs to different drug storage tanks via a dosing tube. When mixing is required, a setting panel is used to set the dosage, and a starter activates a pump to add the drug solution to the dispensing tank via a transfer pipe. After dispensing, a stirring and heating device controls the temperature and improves mixing efficiency. Finally, the drug is dispensed via a dispensing tube. The drug storage tanks can be removed from the locking claws for cleaning, making it convenient to use and dispense drugs.

[0004] However, the above-mentioned solution has certain limitations in practical application. On the one hand, during the medication preparation process, it is necessary to manually use a syringe to draw the medication from the vial and inject it into the corresponding container; moreover, after stirring, the medication needs to be discharged and collected before use. Both of these steps involve exposure of the medication to air, which undoubtedly increases the risk of occupational exposure for medical personnel and poses a potential threat to their health. On the other hand, after medication preparation, some unused medication may remain in the storage container. Due to the lack of effective preservation measures, these residual medications are difficult to store properly, easily leading to medication waste and potential loss of efficacy.

The motor 55 is bolted to the top of the drum cover 52. The output shaft end of the motor 55 is fixedly connected to the upper end of the stirring shaft 53. The motor 55 is electrically connected to the control panel 21.

[0032] like Figure 7As shown, the metering assembly includes a connecting pipe 61, a metering pump a62, a suction pipe a63, a metering pump b64, an injection pipe 65, and a suction pipe b66. Five connecting pipes 61 are welded and fixed at intervals on the upper side wall of the stirring drum 51. A metering pump a62 is installed at the front end of each of the five connecting pipes 61. A suction pipe a63 is welded and fixed through the rear side of each of the five covers 34. The upper ends of the five suction pipes are respectively connected to the front side of the five metering pumps a62. A metering pump b64 is installed on the upper right side of the water storage tank 37 by screws. An injection pipe 65 is connected to the right side of the metering pump b64. The lower end of the injection pipe 65 passes through the cover 52 and communicates with the upper space of the stirring drum 51.

Both the metering pumps a62 and b64 are electrically connected to the control panel 21.

[0033] like Figure 7 , Figure 9 and Figure 10 As shown, the pre-filling assembly includes a drain pipe 71, a water pump 72, a hose 73, a horizontal plate 74, a slide rail 75, a connecting block 76, a needle 77, a placement rack 771, a medicine bag 78, and a protrusion 79. The bottom of the stirring drum 51 is connected to the drain pipe 71, which penetrates the right side panel of the housing 1. The water pump 72 is installed on the upper outer wall of the right side panel of the housing 1 by screws. The upper end of the drain pipe 71 is connected to the water pump 72. A horizontal plate 74 is welded and fixed to the upper outer wall of the right side panel of the housing 1. A slide rail 75 is welded and fixed to the right side of the horizontal plate 74. A connecting block 76 is slidably arranged in the slide rail 75. A needle 77 is connected to the lower part of the connecting block 76. A hose 73 is connected to the upper side of the water pump 72. The hose 73 penetrates the horizontal plate 74, and its right end is connected to the upper part of the connecting block 76. The housing 1 has a connecting block 76 with a mounting bracket 771 welded to the upper side of the outer wall of the right panel. A medicine bag 78 is slidably placed on the mounting bracket 771. A needle 77 can be inserted into the self-sealing membrane set on the upper part of the medicine bag 78. The connecting block 76 has protrusions 79 integrally formed on both sides. The inner walls of both sides of the slide rail 75 have grooves 710 that cooperate with the protrusions 79 at intervals. Initially, the connecting block 76 limits the needle 77 to the position inside the slide rail by cooperating with the protrusions 79 and the upper grooves 710, so as to avoid medical staff being accidentally injured by the needle. When it is necessary to inject the medicine into the medicine bag 78, the medicine bag 78 is first placed on the mounting bracket 771, and then the connecting block 76 is slid down. The water pump 72 is electrically connected to the control panel 21.

[0034] When using this oncology infusion chemotherapy preparation device, medical staff first take the medicine bottle 23 containing chemotherapy drugs and place it in the placement tube 22. Initially, the contact plate 43 is pushed to the position where it fits against the bottom of the placement tube 22 under the action of the return spring 44. The staff presses the medicine bottle 23 down, and the contact plate 43 moves towards the stabilizer 47 under the guidance of the guide rod 42 until it contacts the stabilizer 47. At this time, the suction head 46 will puncture the self-sealing film on the medicine bottle 23 and extend into the bottle. When the contact plate 43 moves, it will drive the L-shaped rack 411 to move together. The L-shaped rack 411, through its cooperation with the gear 410, drives the connecting rod 49 to rotate, thereby opening the valve tube a36 and... The valve on valve b48 is opened, connecting valves a36 and b48 to the inlet pipe 45 and the negative pressure pipe 412, respectively. Then, the operator starts the air pump 413 via control panel 21. The air pump 413 extracts air from the drug storage box 32 through the negative pressure pipe 412 and valve b48, creating a negative pressure state in the drug storage box 32. Under this negative pressure, the medication in the medicine bottle 23 is sequentially drawn into the drug storage box 32 through the suction head 46, inlet pipe 45, and valve a36. Following the above steps, other medications are injected into the remaining four drug storage boxes 32. Afterward, medical staff add sufficient saline solution to the water tank 37. Finally, the information for the mixed medication to be prepared is entered via control panel 21. 1. Immediately control the start of metering pumps a62 and b64 and motor 55. After metering pump a62 starts, it draws out the medicine to be prepared through suction pipe a63 and injects it into the mixing drum 51 through connecting pipe 61. After metering pump b64 starts, it draws out physiological saline from water storage tank 37 through suction pipe b66 and injects it into mixing drum 51 through injection pipe 65. While injecting medicine and physiological saline into mixing drum 51, motor 55 starts and drives stirring shaft 53 to rotate. Stirring blade 54 then stirs and mixes the medicine and physiological saline in mixing drum 51. After injecting a measured amount of medicine and physiological saline, control panel 21 controls metering pumps a62 and b64 to turn off. After stirring for a sufficient time, control panel 21 turns off. The control panel 21 shuts off the motor 55 and starts the water pump 72. The water pump 72 draws out the mixed medicine from the mixing drum 51 through the drain pipe 71 and injects it into the medicine bag 78 on the rack 771 through the hose 73 and the needle 77, realizing the pre-filled storage of the medicine for convenient subsequent rapid use. When it is necessary to prepare other medicines of different concentrations or types, the medical staff starts the metering pump b64, the motor 55 and the water pump 72 in sequence through the control panel 21. The metering pump b64 injects physiological saline into the mixing drum 51. The motor 55 drives the stirring blade 54 to clean the inner wall of the mixing drum 51. Finally, the water pump 72 draws out the cleaning wastewater from the mixing drum 51 and injects it into other medicine bags 78. Then, other medicines can be prepared according to the above steps.

[0035] like Figure 1As shown, it also includes a rotating plate 8, and the upper side of the placement rod is rotatably connected to the rotating plate 8.

[0036] Initially, the rotating plate 8 closes the upper opening of the placement tube 22, preventing the suction head 46 from being contaminated by the external environment. After turning the rotating plate 8 open, medical staff can place the medicine bottle 23 into the placement tube 22 and press the medicine bottle 23 downwards. Then, rotating the rotating plate 8 to reset it, the rotating plate 8 can limit the medicine bottle 23, keeping it in a pressed state, eliminating the need for medical staff to continuously press, saving time and effort.

[0037] like Figure 9 As shown, it also includes a height-adjusting frame 91 and a drawer 92. The height-adjusting frame 91 is welded and fixed to the bottom of the housing 1, and the drawer 92 is slidably arranged in the height-adjusting frame 91.

[0038] The raised frame 91 increases the height of the housing 1, making it easier for medical staff to use the device. Meanwhile, the optimized drawer 92 facilitates the storage of medical supplies by medical staff.

[0039] like Figure 9 As shown, it also includes a support frame 10, and the support frame 10 is welded and fixed to the right side of the heightening frame 91.

[0040] The support frame 10 can lift the bottom of the medicine bag 78 to prevent the medicine bag 78 from being stretched and deformed due to the gravity of the medicine after it is injected into the medicine bag 78.

[0041] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
