Description

Technical Field

[0001] The present invention relates to the technical field of chemotherapy drug preparation, and particularly to a drug preparation device for perfusion chemotherapy in oncology. Background Technique

[0002] Oncology is a secondary discipline of clinical medicine, mainly responsible for the medical treatment of various benign and malignant tumors. As an important branch of clinical medicine, oncology focuses on using non-surgical methods to treat tumors, including chemotherapy, targeted therapy, and immunotherapy, etc.

[0003] Perfusion chemotherapy eliminates cancer cells in the patient's body by locally perfusing chemotherapy drugs. For malignant tumor patients with symptoms such as pleural effusion and ascites, chemotherapy drugs such as bleomycin and cisplatin can be perfused into the chest cavity and abdominal cavity through perfusion chemotherapy, so that the chemotherapy drugs circulate in the body, achieving the effect of eliminating cancer cells and promoting the recovery of the condition.

[0004] When performing perfusion chemotherapy, a drug preparation device is needed to mix solid drugs and liquid drugs together for preparation to facilitate the preparation for chemotherapy. When mixing, some drugs with large particles of solid drugs are directly mixed with the liquid, resulting in poor mixing effect and affecting the chemotherapy effect. Summary of the Invention

The observation window 3 facilitates medical staff to observe the internal situation. The feed pipe 6 facilitates the addition of solid medicine into the dispensing box 1. Through the feeding cylinder 8 and the liquid inlet pipe 7, it is convenient to add liquid medicine into the dispensing box 1, which facilitates the mixing of solid medicine and liquid medicine.

[0031] The mixing unit 5 includes a first crushing frame 501 which is fixedly connected to the lower side of the cover plate 2. Two control rods 510 are rotatably connected to the inner side of the first crushing frame 501. Crushing rollers 521 are fixedly connected to the outer sides of the two control rods 510. A first motor 509 is fixedly connected to the rear side of the first crushing frame 501. The lower end of the liquid inlet pipe 7 passes through the lower side of the cover plate 2 and is fixedly connected to a liquid adding cylinder 504.

A plurality of turntables 522 are fixedly connected to the outer side of the rotating rod 502 and inside the second crushing frame 506. Crushing knives 523 are fixedly connected to the outer sides of the turntables 522. Vertical plates 507 are fixedly connected to the lower sides of the left and right ends of the cover plate 2. Lifting grooves 515 are formed in the outer sides of the vertical plates 507. Lifting blocks 516 are slidably connected to the inner sides of the lifting grooves 515. A connecting plate 517 is fixedly connected to the outer side of the lifting block 516. A filter plate 518 is fixedly connected to the outer side of the connecting plate 517. A U-shaped plate 520 is fixedly connected to the upper side of the filter plate 518. A vibrator 519 is fixedly connected to the outer side of the U-shaped plate 520. The front ends of the two control rods 510 pass through the front side of the first crushing frame 501 and are both fixedly connected to gears 511. When preparing the medicine, first, the liquid medicine enters the medicine preparation box 1 through the liquid adding cylinder 504. The solid medicine first enters the first crushing frame 501. The first motor 509 is started. The first motor 509 drives the control rod 510 to rotate. The control rod 510 drives the gear 511 to rotate. Since the two gears 511 are meshed, the two control rods 510 rotate in opposite directions. The control rod 510 drives the crushing roller 521 to rotate. The two crushing rollers 521 initially crush and cut the solid medicine. The cut medicine falls onto the lower filter plate 518.

Under the vibration action of the vibrator 519, the medicine with large particles is transported to the middle of the medicine preparation box 1 and, under the action of gravity, the medicine with large particles falls into the second crushing frame 506. The second motor 9 is started. The second motor 9 drives the rotating rod 502 to rotate. The rotating rod 502 drives the turntable 522 to rotate. The plurality of crushing knives 523 on the turntable 522 rotate. The crushing knives 523 come into contact with the falling material with large particles, causing the medicine with large particles to be cut again, making the medicine with large particles smaller, facilitating the subsequent mixing. Under the action of gravity, the material quickly falls downward, and the liquid medicine is added to the medicine preparation box 1 through the liquid adding cylinder 504 to be mixed with the crushed medicine. The rotating rod 502 drives the stirring rod 503 to rotate, enabling the stirring rod 503 to fully mix the liquid medicine and the solid medicine.

When preparing the medicine, first, the liquid medicine enters the medicine preparation box 1 through the liquid adding cylinder 504. The solid medicine first enters the first crushing frame 501. The first motor 509 is started. The first motor 509 drives the control rod 510 to rotate. The control rod 510 drives the gear 511 to rotate. Since the two gears 511 are meshed, the two control rods 510 rotate in opposite directions. The control rod 510 drives the crushing roller 521 to rotate. The two crushing rollers 521 initially crush and cut the solid medicine. The cut medicine falls onto the lower filter plate 518.

Under the vibration action of the vibrator 519, the medicine with large particles is conveyed to the middle of the medicine preparation box 1 and, under the action of gravity, the medicine with large particles falls into the second crushing frame 506. The second motor 9 is started. The second motor 9 drives the rotating rod 502 to rotate. The rotating rod 502 drives the turntable 522 to rotate. The multiple crushing knives 523 on the turntable 522 rotate. The crushing knives 523 come into contact with the falling material with large particles, causing the medicine with large particles to be cut again, making the medicine with large particles smaller, facilitating the subsequent mixing. Under the action of gravity, the material quickly falls downward, and the liquid medicine is added to the medicine preparation box 1 through the liquid adding cylinder 504 to be mixed with the crushed medicine.
