Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a trash can for containing medical waste. Background Art

[0002] Medical waste is the waste generated after nursing or doctors perform operations on patients, such as gauze, cotton swabs, syringes, infusion sets, and needles. For example, needles are considered sharps and need to be placed in a sharps container, while other waste can be placed in the yellow trash can.

[0003] If a doctor performs a complex procedure on a patient and there is a lot of waste in the procedure bag, during the medical waste sorting process, some sharps such as needles may be mistakenly missed and placed with gauze and other items in the yellow trash can. Or some medical trainees may mistakenly place sharp medical waste in the yellow trash can. Yellow trash cans are generally cleaned and collected by dedicated staff. If there are sharp medical waste in the yellow trash cans, the cleaning staff will not be aware that there are sharp medical waste in the trash cans, which can easily cause them to be injured by the sharps, resulting in occupational exposure.

[0031] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0032] like Figures 1-4 As shown, a trash can for storing medical waste mainly includes: a trash can body 1 and a trash can cover 2.

[0033] The barrel body 1 has a holding cavity 100 for holding medical waste, and the barrel body 1 has an opening that is connected to the holding cavity 100 and is arranged upward; the barrel cover 2 is movably covered on the opening and can block the opening, and the barrel cover 2 is rotatably connected to the barrel body 1; when the barrel cover 2 is turned away from the opening, medical waste can be put into the holding cavity 100 from the opening; an alarm is provided on the barrel body 1 or the barrel cover 2 (illustrated in the figure). Specifically, the alarm can only emit an alarm sound, or only emit an alarm light, or emit both an alarm sound and an alarm light. The specific implementation method is: the alarm includes a speaker and a light-emitting diode, and the alarm emits an alarm sound through the speaker and an alarm light through the light-emitting diode. During use, the alarm not only emits an alarm sound, but also the light-emitting diode flashes and emits an alarm light, reminding the cleaning personnel that there are sharp metal objects in the medical waste in the trash can, so as to prevent the metal sharp objects from accidentally injuring the cleaning personnel and causing occupational exposure.

[0034] The bottom of the barrel body 1 is provided with a transmitting coil 10, and the lid 2 is provided with a receiving coil 20. When the lid 2 is closed over the opening of the barrel body 1, a metal detection zone is formed between the transmitting coil 10 and the receiving coil 20. The container 100 is then within the metal detection zone. When metal waste, such as a needle, is detected in the metal detection zone, an alarm sounds and illuminates. A single-chip microcontroller is provided on the barrel body 1 or the lid 2, and controls the alarm sound and / or the alarm light.

[0035] It should be explained that the transmitting coil 10 and the receiving coil 20 can be selected as a high-sensitivity detection system controlled by the AT89C51 microcontroller in the prior art. Its principle is as follows: the AT89C51 microcontroller is used to generate two different frequency signals of 10KHz and 20KHz respectively, which are output in sequence and sent to the transmitting coil 10 through a power amplifier; the receiving coil 20 on the other side generates an induced voltage and an induced current under the action of the changing magnetic field generated by the transmitting coil 10; and the area between the transmitting coil 10 and the receiving coil 20 is the metal detection area. If a metal foreign object enters the metal detection area, the induced voltage and induced current in the receiving coil 20 will change due to the eddy current effect of the metal object. The changed signal is processed by a series of hardware circuits and input into the microcontroller; the microcontroller first collects the signal in the initial state of the detector and saves it as a reference signal, while setting a fluctuation range; when the detection signal is received, the microcontroller compares it with the reference signal. If the difference is within the fluctuation range, it is allowed to pass. If the difference exceeds the set fluctuation range, an alarm is issued.

[0036] In actual use, the trash can in this embodiment has a transmitting coil 10 disposed at the bottom of the main body 1 and a receiving coil 20 disposed on the lid 2. When the lid 2 is closed on the main body 1, a metal detection zone is formed between the transmitting coil 10 and the receiving coil 20. When a sharp object (such as a needle) is present in the medical waste thrown into the trash can, an alarm on the trash can will emit an alarm sound and / or an alarm light to alert relevant personnel. On the one hand, it can remind medical staff that a sharp object is present in the medical waste they have thrown in. On the other hand, it can alert the cleaning staff to prevent them from being accidentally injured by the sharp object and avoid occupational exposure. The overall structure of the trash can is simple and easy to use.

[0037] Furthermore, a power supply and a control switch are provided on the trash can body 1 or lid 2, and are electrically connected to the transmitting coil 10. When the control switch is turned on, the power supply supplies power to the transmitting coil 10, generating a magnetic field. When the trash can is not being cleaned, i.e., during idle periods, the control switch is off, and the power supply does not need to be powered in real time, thus ensuring its service life and conserving energy. When the control switch is turned on, the power supply resumes power output. A display screen 14 may also be provided on the trash can body 1 to indicate the specific type of sharp metal objects in the trash can, such as needles.

[0038] The barrel body 1 in this embodiment comprises an outer barrel 12 and an inner barrel 11. The inner barrel 11 is movably mounted within the outer barrel 12. The transmitting coil 10 is mounted on the bottom of the outer barrel 12, below the bottom of the inner barrel 11. The barrel cover 2 comprises an outer cover 21 and an inner cover 22, which are detachably connected to the outer cover 21. The receiving coil 20 is positioned between the outer and inner covers 21 and 22. This ensures that both the transmitting coil 10 and the receiving coil 20 are easily assembled and disassembled.

[0039] The top of the inner tub 11 also features a raised rim 110 that flexibly abuts against the outer tub 12. This rim 110 prevents the inner tub 11 from falling into the outer tub 12, preventing inconvenience in removing the inner tub 11. When emptying the trash, the inner tub 11 can be easily removed from the outer tub 12. At least one through-hole is provided in the raised rim 110, which can accommodate a push-up tool or a finger.

[0040] Optionally, a foot switch 13 is provided on the barrel body 1. When the foot switch 13 is stepped on, the barrel cover 2 can be driven to rotate away from the opening, so that there is no need to manually open the barrel cover 2 to prevent hands from getting dirty.

[0041] In this solution, the trash can can detect whether there are medical waste such as metal sharps in the bin, preventing cleaning personnel from being accidentally injured by sharp objects in medical waste and preventing occupational exposure.
