Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a garbage bin for medical nuclear radiation waste that is automatically labeled and punctured. Background Art

[0002] With the advancement of medical technology, nuclear medicine diagnosis and treatment technology is being rapidly promoted and popularized. With the development of nuclear medicine, nuclear radiation protection is increasingly valued. Radionuclides have strong radioactivity. For patients, this property is used to treat and diagnose diseases. However, nuclear radiation also has certain harm to healthy people. Radioactive substances can enter the body through breathing, skin wounds and digestive tract absorption, causing internal radiation. Gamma radiation can penetrate a certain distance and be absorbed by the body, causing external radiation damage to people.

[0003] In the nuclear medicine department of the hospital, when medical staff perform radionuclide therapy and radionuclide injection operations, some radioactive medical waste with radiation is inevitably generated. According to the provisions of the "Sanitary Protection Management of Medical Radioactive Waste" issued by the Ministry of Health, these radioactive wastes must be stored in special containers. After their specific activity and surface dose rate reach the clean release level, they can be exempted from review and control and treated as ordinary waste. The current treatment method for these radioactive medical wastes is to store them in lead trash cans with a structure similar to ordinary trash cans, and then affix zebra paper as labels on them.

[0004] As for the existing lead trash bins, since the above-mentioned nuclear medical waste contains sharp cones, such as injection needles, which will scratch the trash bags, the health workers are also at high risk of needle stick injuries during the garbage cleaning process. Therefore, based on the above-mentioned trash cans, the current technology also uses sharps boxes for collection, but the sharps boxes do not have nuclear radiation detection and warning functions, which are more dangerous when the radiation is large. In addition, during use, the sharps boxes or trash cans for placing nuclear medical waste need to be labeled with relevant information such as the type of nuclide. The existing labels are pasted with zebra paper, and need to be re-pasted after use and cleaning, which not only causes waste, but also the label may be contaminated by the nuclide. Utility Model Content

[0005] The utility model aims to provide a trash can for medical nuclear radiation waste with automatic labeling and puncture-proof function. A sharp tool box is placed inside the trash can to avoid being scratched when carrying nuclear waste. The trash can can measure and warn of radiation in real time to improve safety.

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] Please also refer to Figures 1 to 3 The following will describe in detail the automatic labeling and puncture-proof medical nuclear radiation waste trash can according to the embodiment of the utility model in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the automatic labeling puncture-proof trash can for medical nuclear radiation waste includes a lead box body 1, a sharps box 2 built into the lead box body 1, a cover plate 3 threadedly connected to the top of the sharps box 2, and a sealing cover 4 clamped on the top of the lead box body 1 is provided on the periphery of the cover plate 3, a carrying plate 5 is fixed inside the lead box body 1, the sharps box 2 is placed inside the carrying plate 5, a first pressure sensor module 6 is embedded at the bottom of the carrying plate 5, a power supply mainboard 7 is provided inside the area between the carrying plate 5 and the lead box body 1, the power supply mainboard 7 is electrically connected to a battery 8, the first pressure sensor module 6 is electrically connected to the power supply mainboard 7, a radiation detection mechanism is provided on the side of the lead box body 1, the radiation detection mechanism is electrically connected to the power supply mainboard 7, a through slot 9 is opened on the side of the lead box body 1 near the bottom end of the lead box body 1, and a zebra paper 10 rotatably connected to the inside of the lead box body 1 is provided inside the through slot 9.

[0022] The radiation detection mechanism includes a mounting groove 11 fixed on the side of the lead box body 1, the mounting groove 11 is connected to the inside of the lead box body 1, a radiation detector 12 is fixed by screws inside the mounting groove 11, and an LED lamp 13 is fixed by screws on the side of the lead box body 1 above the mounting groove 11, and the LED lamp 13 is electrically connected to the radiation detector 12.

[0023] In this embodiment, the radiation detector 12 adopts a conventional product with an existing model number of HJ07-BS9521. After the radiation detector 12 is installed, the LED lamp 13 is electrically connected to the radiation detector 12. Therefore, when the detector inside the radiation detector 12 detects a large amount of radiation, the current passing through the detector increases, and thus the current flowing through the LED lamp 13 increases. At this time, the LED lamp 13 lights up, serving as a warning of the large amount of radiation.

[0024] As an implementation mode, a connecting block 14 is fixed on the inner wall of the lead box body 1, and two connecting blocks 14 are provided. The two connecting blocks 14 are distributed on both sides of the through groove 9, and a pulley 15 is rotatably connected inside the connecting block 14. A track 16 is connected between the two pulleys 15, and the zebra paper 10 is bonded to the outside of the track 16. One of the pulleys 15 is connected to a motor 17, and the motor 17 is electrically connected to the first pressure sensor module 6.

[0025] The zebra paper 10 is arranged in two sections, the colors of the two sections of zebra paper 10 are different, and the lengths of the two sections of zebra paper 10 are consistent, which is the length of the through slot 9.

[0026] The threshold value set by the first pressure sensor module 6 is the mass value of the sharps box 2. At the same time, a second pressure sensor 20 is embedded at the bottom of the supporting plate 5. The second pressure sensor 20 is electrically connected to the LED light 13. The threshold value set by the second pressure sensor 20 is the maximum weight value that the sharps box 2 can bear.

[0027] After placing medical nuclear waste inside the sharps box 2, the mass inside the sharps box 2 increases, and then the threshold value set by the first pressure sensor module 6 at the bottom is exceeded. Therefore, the first pressure sensor module 6 excites an electrical signal. Based on the existing PLC control method, the motor 17 can be controlled to turn on. After the motor 17 is turned on, the pulley 15 is driven, and then the pulley 15 drives the track 16 to rotate, and the zebra paper 10 on the track 16 is driven to rotate. In this embodiment, the color of the zebra paper 10 can be set to be gray for one section and yellow for the other section. Therefore, when the motor 17 is working, the zebra paper 10 will be driven to rotate and its yellow section will be placed inside the through groove 9 for display, indicating that nuclear medical waste is placed inside the lead box body 1.

[0028] At the same time, when the amount of medical waste placed exceeds the limit, the second pressure sensor 20 excites an electrical signal, and excites the LED light 13 to light up through the PLC control method.

[0029] A bent rod 18 is further fixed on the side of the cover 4. The bent rod 18 is provided with a plurality of grooves 19 along the circumferential direction of the cover 4. The side of the lead box body 1 is provided with a plurality of grooves 19. The end of the bent rod 18 away from the cover 4 abuts against the inside of the groove 19.

[0030] When this embodiment is used, the sharps box 2 is placed inside the lead box body 1. After the sharps box 2 is placed, the upper end is clamped on the top of the lead box body 1 using a sealing cover 4 to close the gap between the sharps box 2 and the lead box body 1. At this time, the inside of the through slot 9 near the bottom of the lead box body 1 is displayed in gray. When medical waste is placed in, the cover 3 is unscrewed. After the waste is placed, the inside of the through slot 9 is displayed in yellow. At the same time, during the placement process, the radiation amount is measured by the radiation detector 12. After the radiation amount exceeds the amount, the LED light 13 lights up for warning.

[0031] The battery is a rechargeable lithium battery board, which provides power to the power supply mainboard.
