The medical waste high-temperature sterilization vacuum packaging device according to at least one embodiment of the present disclosure is described below with reference to the accompanying drawings.
At least one embodiment of the present disclosure provides a medical waste high-temperature sterilization vacuum packaging device, as shown in fig. 1-4, at least one embodiment of the present disclosure provides a medical waste high-temperature sterilization vacuum packaging device, which mainly includes a high-temperature high-pressure control room 1, a high-temperature high-pressure box 2, a sterilizing device 3, an exhaust port 4, an air suction device 5, a suction hose 6, a pressure release valve 7, a medical waste inlet 8, a high-temperature high-pressure box medical waste outlet 9, a detachable outlet 10, a conveyor belt 11, a sealing device 12, a film former 13, a secondary packaging box 14, a traction device 15, a reel 16, a reel frame 17, and a single-folding film 18.
Medical waste, particularly medical waste with high-strength infectivity, is simply sterilized and packaged in medical institutions, and has a special storage place or room. Medical waste placed in the storage room is directly introduced into the high-pressure high-temperature tank 2 through the suction unit 5 and the suction hose 6 of the apparatus without being manually transported. Medical wastes are classified into infectious medical wastes carrying pathogenic microorganisms and having a risk of causing transmission of infectious diseases and traumatic medical wastes capable of stabbing or incising a human body. In medical institutions, infectious medical waste, such as masks, protective clothing, and the like, is typically packaged in bags, while traumatic medical waste, such as scalpels, syringes, and the like, is typically packaged using sharps boxes. Therefore, the high-temperature high-pressure tank 2 of the device is divided into an infectious medical waste high-temperature high-pressure tank 2.2 and an injurious medical waste high-temperature high-pressure tank 2.1, and the suction hose 6 is divided into an infectious medical waste suction hose 6.2 and an injurious medical waste suction hose 6.1; wherein the traumatic medical waste suction hose 6.1 is yellow, a material which is not easy to perforate is used, and the infectious medical waste suction hose 6.2 is red. The suction device 5 is connected with a medical waste inlet 8 through a pressure relief valve 7, so that medical waste can smoothly enter the high-temperature high-pressure tank 2 through a suction hose 6. The medical waste inlet 8 is provided as an accessible device, which facilitates the storage of medical waste in the high temperature and high pressure tank 2. The air outlet 4 of the air suction device 5 is connected with the disinfection device 3, and the disinfection device 3 is internally provided with disinfectant, so that viruses carried in exhausted air can be killed.
For example, in the medical waste high-temperature sterilization vacuum packaging device provided by at least one embodiment of the present disclosure, the high-temperature and high-pressure box 2 is operated by the high-temperature and high-pressure control chamber 1, and the sterilization manner in the high-temperature and high-pressure box 2 is damp-heat sterilization, that is, the medical waste is sterilized by high-temperature saturated steam. The high-temperature high-pressure control chamber 1 comprises a water storage device, so that sterilized medical wastes are in saturated water vapor; the temperature rising and controlling device ensures that the temperature in the high-temperature high-pressure box 2 rises and is stable; the pressure control device ensures the pressure in the high-temperature high-pressure box 2, so that the water vapor is not excessively boiled while the temperature is increased; the air leakage device enables the water vapor overflowing from the high-temperature high-pressure tank 2 to be changed into water to be stored. The high-temperature and high-pressure resistant material is used around the high-temperature and high-pressure box 2, so that the high-temperature and high-pressure box can be guaranteed to have enough high temperature and pressure, and no danger is generated.
For example, medical waste sterilized inside the high temperature and high pressure tank 2 enters the secondary packing box 14 through the high temperature and high pressure tank medical waste outlet 9. The medical waste after being sterilized by high pressure is packaged for the second time by using a film, so that the diffusion of infectious viruses in the medical waste can be further blocked, and the further treatment and disposal of the medical waste are facilitated. The secondary package 14 comprises a spool carriage 17, on which spool carriage 17 a spool 16 of single-folded film 18 is arranged, which spool 16 is fed to the film former 13 by unwinding the single-folded film 18. The traction means 15 of the single-folded film 18 comprise two driving wheels, in particular an upper driving wheel and a lower driving wheel, between which a layer of single-folded film 18 is placed, the two driving wheels rotating in opposite directions and being able to transfer the single-folded film 18 to the film former 13. The medical waste entering the secondary packaging container 14 enters the area of the film former 13 by means of the conveyor belt 11, and the film former 13 is able to unfold the single-folded film 18, so as to unfold both edges of the single-folded film 18 so as to wrap it around the medical waste. Medical waste wound by the single-folded film 18 is sent into the area of the sealing device 12 by the conveyor belt 11, the sealing device 12 can seal the single-folded film 18 still opened around the medical waste and perform vacuum packaging, the volume of the medical waste is reduced, meanwhile, the medical waste can be guaranteed not to easily overflow, and meanwhile, whether the packaging is damaged or not is conveniently checked. The packaged medical waste is fed by the conveyor belt 11 to the detachable outlet 10, and the detachable outlet 10 can be considered to be opened to facilitate the removal of the packaged medical waste.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents, and thus the embodiments of the present invention are intended to be merely illustrative examples of the invention and are not to be construed as limiting the invention in any way.

Medical waste enters the high-pressure high-temperature box through the air suction device and the suction hose, and the air suction device
The medical waste is connected with the medical waste inlet through the pressure release valve, so that the medical waste enters the high-temperature high-pressure tank through the suction hose;
s2: medical waste disinfection
The high-temperature high-pressure box is controlled by a high-temperature high-pressure control chamber, and the medical waste is subjected to damp-heat sterilization by high-temperature saturated steam;
s3: secondary package
Medical waste sterilized in the high-temperature high-pressure box enters a secondary packaging box through a medical waste outlet of the high-temperature high-pressure box, and is secondarily packaged by using a film;
s4: vacuum package
The medical waste after secondary packaging is conveyed to the sealing device area by the conveyor belt for vacuum packaging, and the packaged medical waste is conveyed to the detachable outlet by the conveyor belt.
