Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-infection isolation device and a method of using the same. Background Art

[0002] Anti-infection isolation equipment is a series of equipment designed to prevent the spread of pathogens and protect susceptible people and the environment from infection. The anti-infection isolation equipment in medical places mainly includes: personal protective equipment (masks, gloves, protective clothing, goggles, shoe covers and cap covers, etc.), environmental control equipment (air purifiers, negative pressure ward facilities and disinfection equipment, etc.), medical equipment and facilities (isolation bed curtains, isolation beds, isolation vehicles, isolation barriers and children's anti-infection isolation equipment, etc.) and medical waste treatment equipment. Since infectious medical waste (potentially infectious items formed by cotton balls, cotton swabs, drainage cotton strips, gauze and other dressings) need to be uniformly recycled and then transferred to a designated place for destruction, but before transfer and destruction, these infectious medical wastes need to be disinfected and isolated to prevent bacteria and viruses from being generated inside and causing infection, and the above-mentioned medical waste treatment equipment can disinfect and isolate infectious medical waste.

[0003] After searching, the Chinese invention patent with the publication number of CN116763458A discloses an anti-infection isolation device for respiratory internal medicine nursing, including a frame, a flip assembly, a disinfection assembly and a lifting assembly. The outer wall of the frame is provided with a common feeding port and an easily infected feeding port. The top of the frame is provided with a first top plate and a second top plate. The inner bottom of the frame and below the easily infected feeding port is provided with an easily infected box. The inner bottom of the frame and below the common feeding port is provided with a common box. Compared with the prior art, the Chinese invention patent with the publication number of CN116763458A finally realizes the reset spring to be reset inside the connection frame. When reset, the reset plate can be controlled by force to be reset to the state when no feeding is performed. Secondly, when the flip plate and the limit frame are closed, they can contact the inner wall of the conical frame, so that the overall sealing of the frame can be ensured, and bacteria and viruses can be better isolated.

[0004] Although the above-mentioned anti-infection isolation equipment used for respiratory medicine care can autonomously spray disinfectant for disinfection when feeding or cleaning the waste box, the infectious medical waste inside the equipment is exposed and not absolutely isolated, that is, the odor, infectious bacteria and viruses inside the equipment will inevitably be emitted to the outside through the feeding port or the discharging port, which will increase the chance of cross infection, resulting in poor anti-infection isolation effect of the equipment. Therefore, there is a need for an anti-infection isolation equipment that can prevent the odor, infectious bacteria and viruses inside the equipment from being emitted to the outside and causing cross infection. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that odor, infectious bacteria and viruses inside the equipment will inevitably be emitted outward through the feeding port or the discharging port, resulting in poor anti-infection isolation effect of the equipment, and to propose an anti-infection isolation device and its use method.

[0020] A method for using an anti-infection isolation device comprises the following steps:

[0021] S1: Open the cover and feed: open the sealed top cover by stepping down the foot pedal, and then the medical waste can be fed into the inner isolation barrel aligned with the feeding port through the feeding port;

[0022] S2: Open the cover and push the material: When the sealed top cover is opened, the pushing piston away from the feeding port can move outward to push out the medical waste attached to the inner wall of the corresponding inner isolation barrel;

[0023] S3: Open the cover for disinfection: When the sealed top cover is opened, the touch switch can be triggered to start the liquid discharge pump, so that the inclined liquid spray head group can spray the disinfectant onto the inner isolation barrel, the outside of the absorbent cotton sleeve on the end side of the push piston, and the medical waste for disinfection;

[0024] S4: Open the cover to store force: When the sealed top cover is opened, the gas inside the elastic airbag can be squeezed into the interior of the semi-arc fixed shell, causing the semi-arc piston ring to rotate inward to store force;

[0025] S5: Closing the cover and changing position: By releasing the foot pedal and closing the sealed top cover, the inner isolation barrel body carrying materials can be rotated and changed position. After the second change of position, the medical waste inside the inner isolation barrel body enters the garbage bag laid inside the material box body;

[0026] S6: Closing the cover for disinfection: When the sealing top cover is closed, the pushing piston away from the feeding port can be reset inwards so that the absorbent cotton sleeve at its end can smear the absorbed disinfectant onto the inner wall of the inner isolation barrel for disinfection;

[0027] S7: Full-load sealing: As the amount of medical waste in the garbage bag inside the subsequent material box increases, the placement plate is compressed, driving the movable magnetic ring to drop to the effective adsorption distance of the fixed magnetic ring, which causes the pressure alarm to be compressed and sound an alarm to remind relevant personnel to replace the garbage bag, and at the same time, the symmetrical sealing arm seals the garbage bag.

[0028] The present invention has the following beneficial effects:

[0029] 1. In the present invention, the four axially symmetrical inner isolation barrels and the inner isolation plate bodies outside thereof can always isolate the inner space of the upper isolation box into two upper enclosed spaces and a lower connecting space, that is, each time feeding, the medical waste can be isolated and assisted to enter the garbage bag laid inside the material box for centralized collection, thereby preventing the odor, infectious bacteria and viruses inside the upper isolation box and the lower equipment box from being emitted outward through the feeding port, and in the process of stepping down the foot plate to open the sealed top cover, the pushing piston can move outward to push out the medical waste attached to the inner wall of the inner isolation barrel, and in the process of loosening the foot plate to close the sealed top cover, the pushing piston can move inward to enable the absorbent cotton sleeve at its end to smear the absorbed disinfectant onto the inner wall of the inner isolation barrel for disinfection.

[0030] 2. The present invention can store force in the arc-shaped return spring every time feeding is carried out. When the placement plate is pressed to drive the movable magnetic attraction ring to drop to the effective adsorption distance of the fixed magnetic attraction ring, the stored force arc-shaped return spring will immediately drive the semi-arc piston ring to rotate clockwise through the inner ratchet groove and the self-resetting outer ratchet claw, so that the symmetrical sealing arm can seal the garbage bag and prevent the odor, infectious bacteria and viruses inside the upper isolation box and the lower equipment box from being emitted outward through the discharge port.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Embodiment 1

[0048] like Figure 1-Figure 5 , Figure 7 , Fig. 9 and Fig.11As shown, an infection prevention isolation device proposed by the present invention comprises an upper isolation box body 1, a lower equipment box body 2, a feeding port 3, a sealing top cover 4, a waste box body 5, a discharge port 6 and a magnetic side cover 7. The feeding port 3 is opened at the top of the upper isolation box body 1, and the sealing top cover 4 is rotatably arranged on the outside of the feeding port 3. The sealing top cover 4 has a certain weight to ensure the sealing of the feeding port 3. The waste box body 5 is placed inside the lower equipment box body 2 and a garbage bag 11 is laid inside. The discharge port 6 is opened on the outside of the lower equipment box body 2, and the magnetic side cover 7 is rotatably arranged on the outside of the discharge port 6. The interior of the isolation box 1 and the lower equipment box 2 are interconnected, and a foot-operated mechanism 8 for opening the sealed top cover 4 is provided on the outside. The foot-operated mechanism 8 includes a telescopic plate 801 rotatably connected to the bottom of the lower equipment box 2, one end of the telescopic plate 801 is fixedly connected to a foot-operated plate 802, and the other end of the telescopic plate 801 is rotatably connected to an upper push rod 803 slidably connected to the back of the lower equipment box 2, and the top of the upper push rod 803 is located below the connection part of the sealed top cover 4. By stepping down on the foot-operated plate 802 to rotate the telescopic plate 801, the upper push rod 803 can be pushed upward to open the sealed top cover 4;

[0049] The interior of the upper isolation box 1 is provided with an isolation mechanism 9 for isolating the upper space, and the isolation mechanism 9 includes a rotating cylinder 901 rotatably connected to the interior of the upper isolation box 1, and the exterior of the rotating cylinder 901 is fixedly connected with four axially symmetrical inner isolation barrel bodies 902, and the exterior of each inner isolation barrel body 902 is symmetrically fixedly connected with an inner isolation plate body 903, and the interior of each inner isolation barrel body 902 is provided with a pushing piston 904, and each inner isolation barrel body 902 and each pushing piston 904 are provided with a liquid absorbent cotton sleeve 905 on the side contacting the inner wall of the upper isolation box 1, and the liquid absorbent cotton sleeve 905 arranged on the outer side of the inner isolation barrel body 902 can apply disinfectant to the inner wall of the upper isolation box 1, and the liquid absorbent cotton sleeve 905 arranged on the outer side of the pushing piston 904 The cotton sleeve 905 can apply the disinfectant to the inner wall of the corresponding inner isolation barrel body 902. The isolation mechanism 9 also includes a linkage frame 906 embedded in the upper part of the upper push rod 803. The inner side of the linkage frame 906 is rotatably provided with a one-way rotating sawtooth group 907 that can rotate downward and reset upward. The back of the rotating cylinder 901 is fixedly connected with a rotating toothed ring 908 extending to the back of the upper isolation box body 1. The rotating toothed ring 908 is meshed with the one-way rotating sawtooth group 907. When the linkage frame 906 drives the one-way rotating sawtooth group 907 to move upward, the one-way rotating sawtooth group 907 will deflect downward. When the linkage frame 906 drives the one-way rotating sawtooth group 907 to move downward, the one-way rotating sawtooth group 907 can drive the rotating toothed ring 908 to rotate;

[0050] The isolation mechanism 9 also includes a sealed air pressure chamber 909 fixedly connected to the back of the upper isolation box body 1, a piston block 910 is arranged inside the sealed air pressure chamber 909, a piston rod 911 is fixedly connected between the piston block 910 and the upper push rod 803, the end of the sealed air pressure chamber 909 away from the piston block 910 passes through the rotating cylinder 901 and is fixedly connected to the inner wall of the upper isolation box body 1, and a one-way air inlet pipe 912 and a one-way air outlet pipe 913 abutting against the inner wall of the rotating cylinder 901 are arranged outside the sealed air pressure chamber 909, and the rotating cylinder 901 and each inner isolation barrel body are fixedly connected. A connecting hole 914 is provided between each of the inner and outer barrels 902. When the upper push rod 803 drives the piston block 910 to move upward, the gas inside the sealed air pressure chamber 909 can be squeezed into the inner wall of the inner isolation barrel 902 through the connecting hole 914, so that the pushing piston 904 moves to push out the medical waste attached to the inner wall of the inner isolation barrel 902. An elastic telescopic rod 915 is installed between each inner isolation barrel 902 and each pushing piston 904. The elastic telescopic rod 915 can assist the pushing piston 904 in resetting and applying disinfectant to the inner wall of the inner isolation barrel 902.

[0051] A disinfection mechanism 10 for spraying disinfectant is symmetrically arranged on the outside of the lower equipment box 2. The disinfection mechanism 10 includes a liquid storage tank 101 fixedly connected to the side of the lower equipment box 2. The inside of the liquid storage tank 101 is fixedly connected to a liquid outlet pipe 102 extending to the outside. A liquid outlet pump 103 is installed on the outside of the liquid outlet pipe 102. The end of the liquid outlet pipe 102 away from the liquid storage tank 101 is connected to a transfer box 104 embedded in the upper isolation box 1. An inclined liquid spray head group 105 is arranged on the inner side of the transfer box 104. The disinfection mechanism 10 also includes a touch switch 106 connected to the liquid outlet pump 103. The touch switch 106 is installed below the foot pedal 802. By stepping on the foot pedal 802 to open the sealed top cover 4, the touch switch 106 can be triggered to start the liquid outlet pump 103, so that the inclined liquid spray head group 105 can disinfect the inner isolation barrel 902 and the waste.

[0052] The working principle of this embodiment is as follows: Figure 7 As shown, the four axially symmetrical inner isolation barrel bodies 902 and the inner isolation plate body 903 outside thereof can isolate the inner space of the upper isolation box body 1 into two upper enclosed spaces and a lower connected space. When feeding is required, the foot plate 802 can be stepped on to rotate the telescopic plate 801, and the rotation of the telescopic plate 801 will cause the upper push rod 803 to move upward and push open the sealing top cover 4, and then the medical waste is fed into the inner isolation barrel body 902 aligned with the feeding port 3 through the feeding port 3, and finally the foot plate 802 is released to reset the foot mechanism 8 and reset and close the sealing top cover 4, and the feeding is completed;

[0053] like Fig. 9As shown, the one-way air outlet pipe 913 outside the sealed air pressure chamber 909 is aligned and connected with the connecting hole 914 on the bottom of the inner isolation barrel body 902. In the process of stepping on the foot pedal 802 to open the sealed top cover 4, the upper push rod 803 will drive the piston block 910 to move upward through the piston rod 911 to squeeze the gas inside the sealed air pressure chamber 909 into the inner isolation barrel body 902 through the connecting hole 914, so that the pushing piston 904 moves downward and stretches the elastic telescopic rod 915. At the same time, the upper push rod 803 will drive the linkage frame 90 6 and the one-way rotating sawtooth group 907 move upward, but because the one-way rotating sawtooth group 907 can rotate downward, the rotating gear ring 908 is not affected by it. When the foot pedal 802 is stepped down to the lowest point, the touch switch 106 can be triggered to start the liquid outlet pump 103, so that the disinfectant inside the liquid storage tank 101 enters the interior of the transfer box 104 through the liquid outlet pipe 102, so that the inclined liquid spray head group 105 can spray the disinfectant to the inner isolation barrel 902 and the outer side of the liquid absorbing cotton sleeve 905 on the end side of the push piston 904;

[0054] like Figure 4 As shown, in the process of loosening the foot pedal 802 to close the sealing top cover 4, the foot pedal 802 is disengaged from the touch switch 106 to close the liquid pump 103, so that the inclined spray head group 105 stops spraying disinfectant, and at the same time, the upper push rod 803 drives the piston block 910 to move downward and reset through the piston rod 911, so that the air inside the rotating cylinder 901 enters the interior of the sealed air pressure chamber 909 through the one-way air inlet pipe 912, and the upper push rod 803 drives the linkage frame 906 and the one-way rotating sawtooth group 907 to move downward, so that the rotating gear ring 908 drives the rotating cylinder 901 and the inner isolation barrel body 902 and the inner isolation plate body 903 outside thereof rotate, and the inner isolation barrel body 902 at the bottom rotates and no longer abuts and aligns with the end of the one-way air outlet pipe 913, and the stretched elastic telescopic rod 915 immediately drives the pushing piston 904 to reset inward, and makes the absorbent cotton sleeve 905 at its end smear the absorbed disinfectant to the inner wall of the upper isolation box body 1 for disinfection, so that the inner isolation barrel body 902 aligned with the feeding port 3 and loaded with materials can be rotated 90° for replacement, and at the same time, the next inner isolation barrel body 902 can be rotated 90° to align with the feeding port 3;

[0055] Subsequently, the waste inside the inner isolation barrel 902 will enter the garbage bag 11 laid inside the material box 5, that is, when feeding, the input medical waste can be isolated and assisted to enter the garbage bag 11.

[0056] The main difference between this embodiment and the prior art is that: in this embodiment, the four axially symmetrical inner isolation barrels 902 and the outer inner isolation plate body 903 can always isolate the internal space of the upper isolation box body 1 into two upper enclosed spaces and a lower connecting space, that is, each time the material is fed, the medical waste can be isolated and assisted to enter the garbage bag 11 laid inside the material box body 5 for centralized collection, so as to prevent the odor, infectious bacteria and viruses inside the upper isolation box body 1 and the lower equipment box body 2 from being emitted outward through the feeding port 3, and in the process of stepping down the foot plate 802 to open the sealing top cover 4, the pushing piston 904 can move outward to push out the medical waste attached to the inner wall of the inner isolation barrel body 902, and in the process of loosening the foot plate 802 to close the sealing top cover 4, the pushing piston 904 can move inward to enable the absorbent cotton sleeve 905 at its end to smear the absorbed disinfectant to the inner wall of the inner isolation barrel body 902 for disinfection.

[0057] Embodiment 2

[0058] like Figure 1-Figure 13 As shown, based on the first embodiment, the inner lower part of the upper isolation box body 1 is symmetrically fixedly connected with a baffle plate 17 extending to the inner upper part of the lower equipment box body 2, and the baffle plate 17 is located outside the semi-arc fixed shell 163 and located at the upper part of the waste box body 5. The setting of the baffle plate 17 can prevent medical waste and disinfectant from falling to the outside of the waste box body 5. The top of the waste box body 5 is symmetrically rotatably connected with a rotating shaft 12, and the outside of the rotating shaft 12 is fixedly connected with a sealing arm 13. The sealing arm 13 A side opening 14 is provided between the rotating shaft 12 for the edge of the garbage bag 11 to pass through. When the garbage bag 11 is laid inside the waste box 5, the two long sides of the garbage bag 11 need to be folded over the top outside of the waste box 5, and the two short sides of the garbage bag 11 need to be passed through the symmetrical side openings 14 and folded over the top outside of the waste box 5.

[0059] An auxiliary mechanism 16 for assisting the symmetrical sealing arm 13 in sealing is arranged inside the lower equipment box 2. The auxiliary mechanism 16 comprises a placement plate 161 slidably connected to the lower part of the lower equipment box 2 and an elastic telescopic frame 162 symmetrically fixedly connected to the bottom of the upper isolation box 1. The waste box 5 is placed on the top of the placement plate 161. The top of the placement plate 161 is symmetrically fixedly connected to a limit plate 166. A movable magnetic ring 167 and a pressure alarm 168 are installed at the bottom of the placement plate 161. When the pressure alarm 168 is compressed, an alarm sound will be issued to remind relevant personnel. A fixed magnetic ring 169 embedded in the bottom of the lower equipment box 2 is arranged below the movable magnetic ring 167. An extrusion spring group 170 is fixedly connected between the placement plate 161 and the lower equipment box 2. The original length of the extrusion spring group 170 is greater than the effective adsorption distance between the movable magnetic ring 167 and the fixed magnetic ring 169.

[0060] The bottom of the elastic telescopic frame 162 is fixedly connected with a semi-arc fixed shell 163, and a semi-arc piston ring 171 is arranged inside the semi-arc fixed shell 163. The outside of the semi-arc piston ring 171 is fixedly connected with a piston plate 172 located inside the semi-arc fixed shell 163. The outside of the semi-arc fixed shell 163 is fixedly connected with a connecting butt pipe 173. When gas is introduced into the interior of the semi-arc fixed shell 163 through the connecting butt pipe 173, the piston plate 172 can drive the semi-arc piston ring 171 to rotate counterclockwise. The side of the piston plate 172 away from the connecting butt pipe 173 is symmetrically fixedly connected to the semi-arc fixed shell 163. Arc-shaped return spring 174, a rotating column 164 is arranged inside the semi-arc fixed shell 163, the rotating column 164 is rotatably connected to the inner side of the semi-arc piston ring 171, both ends of the semi-arc piston ring 171 are provided with evenly distributed inner ratchet grooves 175, both ends of the outer side of the rotating column 164 are provided with two rotating grooves 176, the insides of the two rotating grooves 176 are rotatably connected with self-resetting outer ratchet pawls 177, the semi-arc piston ring 171 can drive the rotating column 164 to rotate clockwise through the inner ratchet grooves 175 and the self-resetting outer ratchet pawls 177, and the bottom of the rotating column 164 is provided with a concave driving groove 165 for driving the convex driving block 15;

[0061] The auxiliary mechanism 16 also includes a mounting box 178 fixedly connected to the back of the lower equipment box 2, the top of the mounting box 178 is provided with an upper opening 179 and the side is symmetrically provided with a lower sliding opening 180, the interior of the mounting box 178 is slidably connected to an extrusion block 181 fixedly connected to the upper push rod 803, the top of the extrusion block 181 is fixedly connected to an elastic air bag 182, the top of the elastic air bag 182 is provided with a one-way air pipe 183 passing through the upper opening 179, and the outer upper part of the elastic air bag 182 is symmetrically fixed. The fixed connection is provided with a one-way butt pipe 184 which passes through the lower sliding opening 180 and extends to the interior of the lower equipment box 2. The one-way butt pipe 184 is fixedly connected to the placement plate 161. The ends of the connecting butt pipe 173 and the one-way butt pipe 184 are both provided with elastic air sealing rings 185 which are pressed against each other. By stepping down the foot plate 802 to open the sealing top cover 4, the extrusion block 181 can press the elastic air bag 182 so that the gas inside the elastic air bag 182 is squeezed into the interior of the semi-arc fixed shell 163.

[0062] The working principle of this embodiment is as follows: Figure 4 and Fig.10 As shown, in the process of stepping down the foot plate 802 to open the sealing top cover 4, the upper push rod 803 drives the extrusion block 181 to press the elastic airbag 182, so that the gas inside the elastic airbag 182 is squeezed into the inside of the one-way butt joint 184, and the gas entering the one-way butt joint 184 enters the interior of the semi-arc fixed shell 163 through the connecting butt joint 173, and the gas entering the interior of the semi-arc fixed shell 163 pushes the piston plate 172 to move and squeezes the arc-shaped return spring 174, so that the semi-arc piston ring 171 rotates inwardly, and in the process of loosening the foot plate 802 to close the sealing top cover 4, the outside air enters the elastic airbag 182 through the one-way return air pipe 183 to reset the elastic airbag 182, that is, each time the material is fed, the semi-arc piston ring 171 can rotate once and the arc-shaped return spring 174 can store force once;

[0063] As the amount of medical waste in the garbage bag 11 placed inside the waste box 5 gradually increases, the placement plate 161 will gradually move downward to compress the spring assembly 170, and the elastic telescopic frame 162 will drive the semi-arc-shaped fixed shell 163 to gradually move downward. When the placement plate 161 is compressed and drives the movable magnetic ring 167 to drop to the effective adsorption distance of the fixed magnetic ring 169, the fixed magnetic ring 169 will immediately adsorb the movable magnetic ring 167 to make the placement plate 161 move down to the lowest point, and the pressure alarm 168 will sound an alarm when it is compressed to remind relevant personnel to replace the garbage bag. 11, and at the same time, the one-way docking tube 184 moves downward and disengages from the connecting docking tube 173, and the arc-shaped return spring 174 with stored force immediately drives the semi-arc-shaped piston ring 171 to rotate clockwise through the piston plate 172, and the semi-arc-shaped piston ring 171 rotating clockwise can drive the rotating column 164 to rotate clockwise through the inner ratchet groove 175 and the self-resetting outer ratchet 177, and the rotating column 164 rotating clockwise drives the convex driving block 15 to rotate clockwise through the concave driving groove 165, so that the symmetrical sealing arm 13 seals the garbage bag 11;

[0064] Then the relevant personnel opens the magnetic side cover 7, holds the top of the garbage bag 11 and then takes out the waste box 5. After taking out the waste box 5, the garbage bag 11 is manually tied. When the waste box 5 is taken out, the placement plate 161 is no longer under pressure, and the compressed extrusion spring group 170 will drive the placement plate 161 to reset, and make the one-way docking tube 184 move up and dock with the connecting docking tube 173, and then rotate the rotating column 164 clockwise to reset it, so that the rotating column 164 drives the concave driving groove 165 to rotate and reset, and finally replace the new garbage bag 11 and reset the waste box 5.

[0065] The main difference between this embodiment and the prior art is that in this embodiment, each time material is added, the arc-shaped return spring 174 can be charged. When the placement plate 161 is pressed and drives the movable magnetic ring 167 to drop to the effective adsorption distance of the fixed magnetic ring 169, the charged arc-shaped return spring 174 will immediately drive the semi-arc piston ring 171 to drive the rotating column 164 to rotate clockwise through the inner ratchet groove 175 and the self-resetting outer ratchet 177, so that the symmetrical sealing arm 13 can seal the garbage bag 11, thereby preventing the odor, infectious bacteria and viruses inside the upper isolation box 1 and the lower equipment box 2 from being emitted outward through the discharge port 6.

[0066] Embodiment 3

[0067] like Fig.14 As shown, based on the first and second embodiments, a method for using infection prevention isolation proposed by the present invention includes the following steps:

[0068] S1: Open the cover and feed: by stepping down the foot pedal 802 to open the sealed top cover 4, the medical waste can be fed into the inner isolation barrel 902 aligned with the feeding port 3 through the feeding port 3;

[0069] S2: Open the cover and push the material: When the sealing top cover 4 is opened, the pushing piston 904 away from the feeding port 3 can move outward to push out the medical waste attached to the inner wall of the corresponding inner isolation barrel 902;

[0070] S3: Open the cover for disinfection: When the sealed top cover 4 is opened, the touch switch 106 can be touched to start the liquid discharge pump 103, so that the inclined liquid spray head group 105 can spray the disinfectant onto the inner isolation barrel 902, the outside of the absorbent cotton sleeve 905 on the end side of the push piston 904, and the medical waste for disinfection;

[0071] S4: Open the cover to store force: When the sealing top cover 4 is opened, the gas inside the elastic airbag 182 can be squeezed into the interior of the semi-arc fixed shell 163, so that the semi-arc piston ring 171 rotates inward to store force;

[0072] S5: Closing the cover and changing position: By releasing the foot pedal 802 and closing the sealing top cover 4, the inner isolation barrel 902 carrying materials can be rotated and changed position. After the second change of position, the medical waste inside the inner isolation barrel 902 enters the garbage bag 11 laid inside the material box 5;

[0073] S6: Closing the cover for disinfection: When the sealing top cover 4 is closed, the pushing piston 904 away from the feeding port 3 can be reset inwards so that the absorbent cotton sleeve 905 at its end can smear the absorbed disinfectant onto the inner wall of the inner isolation barrel 902 for disinfection;

[0074] S7: Full load sealing: As the amount of medical waste in the garbage bag 11 inside the subsequent material box 5 increases, the placement plate 161 is compressed, driving the movable magnetic ring 167 to drop to the effective adsorption distance of the fixed magnetic ring 169, which causes the pressure alarm 168 to be compressed and sound an alarm to remind relevant personnel to replace the garbage bag 11, and at the same time causes the symmetrical sealing arm 13 to seal the garbage bag 11.
