[0002] When handling highly pathogenic microbial materials and waste in high-level biosafety laboratories, direct participation of personnel will bring a high risk of infection. Automated robots for waste disposal can greatly reduce the risk of human exposure and ensure the safety of laboratory personnel.

[0003] Since biosafety laboratory waste may contain pathogens, it needs to be strictly disinfected and sterilized after packaging to ensure biosafety. However, existing biosafety laboratory waste collection devices require complex packaging work and are not suitable for convenient use by automated robots. Summary of the invention

[0024] Example 1

[0025] refer to Figure 1-5 , a biosafety waste collection device that can be used by an automated robot, comprising:

[0026] Barrel 1;

[0027] A cover body 2, which is detachably arranged on the top of the barrel body 1 and is sealed and connected to the barrel body 1; a respirator 3 is detachably connected to the cover body 2, wherein when high-temperature and high-pressure steam is required for sterilization, the high-temperature and high-pressure steam can enter the barrel body 1 through the respirator 3 to sterilize the waste under high pressure;

[0028] The base 6 is provided with a U-shaped groove 8 and a placement hole 7, the U-shaped groove 8 and the placement hole 7 are arranged side by side, and the opening of the U-shaped groove 8 is located at the edge of the base 6;

[0029] The barrel body 1 is provided with a handle 13 adapted to be gripped by an automated robot, and a limit block 11 is provided at the lower part of the barrel body 1;

[0030] A cover body 2, which is detachably arranged on the top of the barrel body 1 and is sealed and connected to the barrel body 1; a respirator 3 is detachably connected to the cover body 2; a joint where the cover body 2 is connected to the respirator 3 is provided with a clamping groove 10 adapted to be clamped by an automated robot;

[0031] The base 6 is provided with a U-shaped groove 8 and a placement hole 7, the U-shaped groove 8 and the placement hole 7 are arranged side by side, and the opening of the U-shaped groove 8 is located at the edge of the base 6; the U-shaped groove 8 is provided with a limiting groove 12, and the limiting block 11 of the barrel body 1 is inserted into the limiting groove 12 to limit the vertical movement of the barrel body 1;

[0032] A positioning label is provided on the base 6, and the positioning label is provided between the U-shaped groove 8 and the placement hole 7, so as to quickly calibrate the relative position of the automated robot arm and the barrel body 1 and the cover body 2, so as to enable the automated robot arm to take the cover body, cover the cover, and replace the cover body and barrel body with a new one.

[0033] Among them, the limiting block 11 on the barrel body 1 cooperates with the limiting groove 12 on the U-shaped groove 8. When the barrel body 1 is placed in the U-shaped groove 8, the vertical movement of the barrel body 1 can be limited, thereby adapting the automated robot to remove the cover body 2.

[0034] In this embodiment, the respirator 3 uses hydrophobic and high temperature resistant (above 134°C) PTFE (polytetrafluoroethylene) multi-pleated high efficiency filter material with a filtration accuracy of 0.2 microns and resistant to high temperature and high humidity environments.

[0035] In this embodiment, the upper end of the barrel body 1 is provided with a tapered groove 4 that is sealed with the cover body 2 , and a sealing strip 5 is provided on the cover body 2 . The sealing strip 5 cooperates with the tapered groove 4 to achieve sealing between the cover body 2 and the barrel body 1 .

[0036] The sealing strip 5 is made of silicone or fluororubber with a temperature resistance of more than 134°C.

[0037] The sealing strip may be a V-shaped sealing strip or an O-shaped sealing strip, preferably an O-shaped sealing strip.

[0038] In this embodiment, the barrel body 1 and the cover body 2 are made of corrosion-resistant metal material.

[0039] In this embodiment, a handle is provided on the barrel body 1.

[0040] Specifically, the handle can be a single handle or a symmetrical handle, preferably a symmetrical handle, which is installed on the outer side wall of the barrel body 1, or can be mounted on the position of the barrel body 1 close to the cover body 2, or can be mounted on the opening of the barrel body 1, preferably installed at the opening of the barrel body 1.

[0041] The biosafety waste collection device provided in this embodiment can be used by an automated robot. When in use, the cover body 2 and the barrel body 1 are separated, and the waste is discarded into the barrel body 1. When the top of the waste does not exceed the sealing surface, the cover body 2 is clamped by a robotic arm, and the cover body 2 can be conveniently and tightly installed on the barrel body 1, thereby achieving biosafety isolation of the waste.

[0042] Due to the barrier of the high-efficiency filter material in the respirator, the pathogenic microorganisms contained in the waste inside the barrel body 1 cannot escape to the outside of the barrel through the respirator 3 with high-efficiency filtration.

[0043] When the biosafety waste collection device that can be used by an automated robot is placed in an autoclave for sterilization, high-temperature and high-pressure steam can enter the barrel body 1 through a respirator 3 with high-efficiency filtration to sterilize the waste under high pressure.

[0044] During high-pressure sterilization, due to the interconnection function of the respirator 3, high pressure will not be generated inside and outside the collection barrel, which will affect the sealing between the cover body 2 and the barrel body 1.

[0045] After high-pressure sterilization, the robotic arm can clamp the handle of the barrel 1 and take the collection barrel out of the high-pressure sterilizer. Due to the effect of the high-temperature and high-humidity high-efficiency filtering respirator, when the collector is taken out from the non-clean side, it can also ensure that the sterilized waste is not contaminated by pathogenic microorganisms in the external environment, thereby achieving biosafety during waste transfer and sterilization disposal.

[0046] In this embodiment, the positioning tag is a two-dimensional code 9, and the two-dimensional code 9 is used for positioning.

[0047] In other embodiments, the QR code 9 may also be used for other related functions such as identifying device information.

[0048] Specifically, the placement hole 7 of the base 6 is used to place the barrel body 1 of the collection barrel, the U-shaped groove 8 is used to place the cover body 2, and the QR code 9 for positioning is processed in the middle position.

[0049] In this embodiment, the position where the barrel body 1 is placed is equipped with a tapered guide device. The automated robot clamps the barrel body 1 of the collection barrel. When the bottom touches the bottom surface of the base 6, the robot pushes the barrel body 1 to conveniently place it at the predetermined position.

[0050] At the same time, during the use of the robot, the relative position of the automated robot arm and the waste collection bucket can be quickly calibrated by scanning the QR code 9 of the base 6 through the visual sensor. Thus, the collection cover can be simply and accurately taken from the collection cover position and accurately covered on the collection bucket to achieve reliable sealing. Since the base 6 has a certain wrapping height, the stability of the bucket body 1 can be ensured during the installation of the cover body 2.

[0051] In addition, the biosafety waste collection device provided in this embodiment that can be used by an automated robot does not contain electronic components, has strong adaptability to disinfection and sterilization, and is highly adaptable to the mechanical arm of an automated robot. It does not require additional electric actuators in a biosafety laboratory, thus avoiding more disinfection risks. At the same time, through the positioning verification of the QR code, it is easy and convenient to take out and cover the cover, and replace the cover and barrel with a new one.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
