Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a chemotherapy drug waste recovery device. Background Art

[0002] Chemotherapy drugs, or anti-tumor drugs, can act on different links of tumor cell growth and reproduction to inhibit or kill tumor cells. They are currently the main drugs for treating tumors. Clinically, cancer patients are mainly treated by infusion, but the main substance in the waste after infusion chemotherapy is cytotoxic drugs, which are extremely dangerous to the human body. If the human body is overexposed, there is a possibility of deformity, mutation, or cancer. Therefore, the recycling of empty bottles of chemotherapy drug infusion is extremely critical.

[0003] At present, most of the recycling trash cans used in hospitals have downward pressure or pedal-operated lids. The downward pressure lids are mainly opened towards the inside of the barrel under the action of gravity of the empty infusion bottle. At this time, the empty infusion bottle will directly contact the lid, and the residual drugs in the bottle may be contaminated on the outer surface of the lid, so that the drugs are exposed and evaporated into the air, which can easily cause direct contact contamination to medical staff. During the opening and closing process of the pedal-operated lid, the volatile residual substances in the barrel can easily be dissipated into the environment, and even splashed onto the medical staff during the opening and closing process, endangering their health.

[0004] In order to solve the above problems, patent CN 202120499282.X discloses a trash can for recycling empty bottles of chemotherapy drug infusion, including a barrel body, a barrel cover is provided at the upper end of the barrel body, a ramp slide extending to the inside of the barrel body is provided on the barrel cover, a baffle is hinged on the outer side of the outlet end of the ramp slide, and a first absorption layer is provided on the inner wall of the ramp slide. When medical staff need to recycle empty bottles of chemotherapy drug infusion, they can directly put the infusion bottle into the opening of the ramp slide. The infusion bottle will push the baffle at the outlet end along the slide under the action of gravity and fall into the trash can. Medical staff do not need to manually open and close the barrel cover, which avoids direct contact and avoids residual drugs from splashing on the medical staff. In addition, the absorption layer on the inner wall of the recovery slide can quickly absorb the residual drugs, avoid the volatilization of drugs into the air, and reduce the harm caused by chemotherapy waste to the human body.

[0005] However, the inventors believe that the infusion bottles used in existing chemotherapy are generally made of plastic and are relatively light in weight. Since the baffle is connected to the spring, it is not necessarily possible to push the baffle open directly. In addition, other chemotherapy waste such as syringes are relatively light in weight. Therefore, the above technology can be further improved. Utility Model Content

The waste can be further disinfected, and the harm of chemotherapy waste to the human body can be effectively reduced.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemotherapy drug waste recycling device, comprising a recycling cylinder, a partition plate is fixed inside the recycling cylinder, the partition plate divides the recycling cylinder into a recycling collection area below and a disinfectant storage area above, an arc-shaped partition plate is fixed inside the disinfectant storage area, a recycling port fixed on one side of the arc-shaped partition plate is provided, the recycling port is connected with the recycling collection area, a telescopic rubber ring is fixed at the end of the recycling port facing the recycling collection area, an angular sealing plate slidably connected to the partition plate is provided below the telescopic rubber ring, the angular sealing plate is connected with an automatic control component, an annular conduit is screwed inside the recycling collection area, a connecting pipe is fixed on the upper end of the annular conduit, the connecting pipe is connected with the disinfectant storage area away from the end of the annular conduit, a power module is fixed on the side of the recycling cylinder, a plug-in wire is connected to the outside of the power module, and the power module is connected in series with the automatic control component.

[0028] In this embodiment, the recycling cylinder 1 is mainly used to collect drug waste used in chemotherapy treatment, mainly including infusion bottles and infusion auxiliary equipment.

[0029] As an implementation mode, the automatic control part includes a support frame 13 mounted on the outside of the recovery port 6, a cylinder 14 is fixed on the support frame 13, and the cylinder 14 is symmetrically arranged about the middle part of the support frame 13. A driving rod 15 is fixed to the output end of each cylinder 14, and the driving rod 15 passes through the partition plate 2 and is fixedly connected to the angle sealing plate 8. It also includes a photoelectric control switch 16 fixed on the inner wall of the recovery port 6, and the photoelectric control switch 16 is connected in series with the power module 11 and the cylinder 14, wherein the support frame 13 is fixed inside the recovery cylinder 1, and a guide rod can also be arranged on the angle sealing plate 8 to ensure the stable movement of the angle sealing plate 8.

[0030] A spring 17 is sleeved on the outside of the driving rod 15 , one end of the spring 17 is fixed to the bottom of the partition plate 2 , and the other end is fixed to the angle sealing plate 8 .

[0031] The photoelectric control switch 16 used is a conventional product, generally including a laser transmitter and a laser receiver. When waste appears inside the recycling port 6, the photoelectric control switch 16 controls the conduction circuit, thereby conducting the cylinder 14. After the cylinder 14 is driven, the drive rod 15 is extended. Then, after the cylinder 14 is opened, the drive rod 15 moves away from the partition plate 2, and the spring 17 sleeved thereon begins to stretch. At the same time, the drive rod 15 drives the angle sealing plate 8 to move away from the bottom of the recycling port 6. At this time, the space between the recycling port 6 and the angle sealing plate 8 is There is a gap, and the waste inside the recovery port 6 can fall into the above-mentioned recovery collection area 3 along the gap. When there is no waste inside the recovery port 6, the photoelectric control switch 16 is in a closed state, and the cylinder 14 is not opened at this time.

When cleaning the recovery cylinder 1, tap water can be added to the disinfectant storage area 4 along the liquid inlet 29, and tap water can be sprayed by placing any object between the photoelectric control switches 16 to clean the recovery cylinder 1, and the cleaned waste water is discharged along the discharge port 25.

[0039] The principle of the utility model is as follows: when in use, a power module 11 of ACDC 220V to 12V is selected, and the power supply is connected by plugging in the power wire 12, and a number of disinfectants are placed inside the disinfectant storage area 4. After the waste generated during chemotherapy, such as the infusion bottle, enters along the recovery port 6, it first passes through the photoelectric control switch 16, and the cylinder 14 is automatically controlled to open by the photoelectric control switch 16, and the driving rod 15 drives the angle sealing plate 8 to move downward, and the infusion bottle automatically falls into the recovery cylinder 1. At the same time, the water pump 18 is turned on to spray the disinfectant inside the recovery cylinder 1, and then disinfection is performed after each waste falls in, and after the waste falls into the recovery cylinder 1, the angle sealing plate 8 at the bottom of the recovery port 6 can automatically contact the telescopic rubber ring 7, and the recovery port 6 is sealed again to prevent the residual medicine in the waste from volatilizing.
