Description

Technical Field

[0001] This invention relates to the field of medical waste recycling technology, and more specifically to a waste recycling device for preventive medicine. Background Technology

[0002] Current preventive medical waste storage bags often employ a rotating gooseneck design with binding straps for sealing during recycling. The typical process requires operators to manually rotate the gooseneck structure at the top of the bag to tighten the opening, followed by manual securing with plastic binding straps.

[0003] When healthcare workers operate the rotating and collecting garbage bags, the gas accumulated inside the bags can easily escape suddenly due to compression, potentially exposing the operator to aerosols containing pathogenic microorganisms and posing a direct risk of infection. Simultaneously, the entire binding process relies entirely on manual labor, resulting in low efficiency, poor operational consistency, and difficulty in ensuring the tightness of the binding, which may lead to incomplete sealing. Operators must be in close contact with the open waste bags, further increasing the possibility of contact exposure and cross-contamination. This method, when disposing of infectious waste, especially in the context of preventive medicine emphasizing source control and occupational protection, exposes problems such as high health risks, cumbersome operation, reliance on manual labor, and insufficient reliability of protective measures. Therefore, this paper proposes a waste recycling device for preventive medicine to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a preventive medical waste recycling device to solve the technical problem that, when medical personnel operate the rotating and collecting garbage bags, the operator needs to be in close contact with the open garbage bag. When rotating and collecting the garbage bag, the gas accumulated inside the bag can easily escape suddenly due to compression, which may expose the operator to aerosols containing pathogenic microorganisms, posing a direct risk of infection.

[0005] The technical solution adopted in this invention is a preventive medical waste recycling device, comprising: The recycling bin and the first servo motor are fixedly installed on the upper side of the recycling bin; The recycling bin is equipped with two symmetrically distributed traction hooks in the middle. The traction hooks can hook the loops of garbage bags. The output end of the first servo motor can drive the traction hooks to rotate. The traction hooks can rotate along the central axis of the first servo motor.

[0006] In a preferred embodiment, a rotating mechanism is mounted on the upper side of the recycling bin, the rotating mechanism comprising: A transmission disc is fixedly mounted on the upper side of the recycling bin, and the transmission disc has two centrally symmetrically distributed swirl grooves. The rotating rod, with its central transmission assembly connected to the output end of the first servo motor; A support rod is assembled to the end of the rotating rod and slidably assembled to the inner side of the rotary groove, and the traction hook is fixedly installed at the lower end of the support rod.

[0007] In a preferred embodiment, the support rod is slidably mounted on the lower side of the rotating rod, and the vortex groove is a spiral groove.

[0008] In a preferred embodiment, the lower end of the rotating rod is provided with a sliding groove, the upper end of the support rod is fixedly equipped with a slider that is slidably connected to the sliding groove, and an angle brace is installed between the support rod and the slider.

[0009] In a preferred embodiment, two centrally symmetrically distributed pressure plates are rotatably mounted inside the recycling bin.

[0010] In a preferred embodiment, the traction hook has an anti-slip groove in the middle.

[0011] In a preferred embodiment, the recycling bin is hinged to a door on the front side, and a movable storage box is slidably fitted inside the recycling bin, which can hold garbage bags.

[0012] In a preferred embodiment, a ramp is fixedly installed on the lower side of the recycling bin.

[0013] In a preferred embodiment, the upper side of the recycling bin is equipped with a sealing door for dispensing.

[0014] In a preferred embodiment, the dispensing sealing door is slidably and sealingly mounted on the recycling bin, and a driving mechanism is mounted on the upper side of the recycling bin, the driving mechanism comprising: The second servo motor is fixedly installed inside the recycling bin; A rotating shaft is rotatably installed inside the recycling bin and is driven by the output end of the second servo motor. The rotating shaft is connected to the delivery sealing door. A gear is fixedly installed in the middle of the rotating shaft, and the delivery sealing door is fixedly installed on a rack that meshes with the gear.

[0015] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: When medical staff need to collect the garbage bags, there is no need to manually touch the bags. They simply hook the bag's loops onto two symmetrically distributed traction hooks. Then, the first servo motor is activated, and its output drives the traction hooks to rotate along their central axis. As the traction hooks rotate, the bag's loops are also rotated, causing the bag opening to gradually tighten.

[0016] During this process, medical staff can stay away from the recycling bin, avoiding close contact with open garbage bags. When the traction hook rotates to collect the garbage bag, even if the gas accumulated inside the bag escapes due to compression, it will be released inside the recycling bin rather than directly hitting the operator. This effectively reduces the operator's risk of direct infection from pathogenic microorganism aerosols. The non-contact collection of garbage bags through mechanical transmission solves the infection risk problem caused by manual operation in existing technologies. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0021] Example: like Figure 1-7 As shown, this embodiment provides a preventive medical waste recycling device, including: The recycling bin 1 and the first servo motor 11 are fixedly installed on the upper side of the recycling bin 1. Two symmetrically distributed traction hooks 12 are installed in the middle of the recycling bin 1. The traction hooks 12 can hook the loops of garbage bags. The output end of the first servo motor 11 can drive the traction hooks 12 to rotate. The traction hooks 12 can rotate along the central axis of the first servo motor 11. An anti-slip groove 15 is provided in the middle of the traction hook 12 to prevent the loops of the garbage bag from detaching from the traction hook 12 when it rotates. Two symmetrically distributed pressure plates 14 are rotatably mounted inside the recycling bin 1. When assembling a garbage bag inside the recycling bin 1, first open the garbage bag opening so that the pressure plates on both sides are placed inside the garbage bag, and then hook the two loops of the garbage bag onto the traction hooks 12 on both sides respectively.

[0022] The two loops of the garbage bag can be hooked onto the two traction hooks 12 on both sides. The first servo motor 11 drives the two traction hooks 12 to rotate, thereby causing the opening of the garbage bag, which is three-quarters full of garbage, to twist. This eliminates the need for medical staff to manually twist the garbage bag when taking it out. They can directly use the strapping to quickly tie the opening of the garbage bag with a gooseneck knot. Twisting the opening of the garbage bag in advance can prevent the gas inside the garbage bag from spraying out and hitting the face of medical staff or being inhaled in large quantities when the garbage bag is manually twisted. The pressure plate 14 ensures that the opening of the garbage bag is open, making it easy for medical waste to enter the garbage bag. As the traction hook 12 gradually rotates the garbage bag, the pressure plates 14 on both sides will rotate upward and detach from the garbage bag due to the closing of the garbage bag opening. An exhaust device can be installed on the top or rear of the recycling bin 1, which can be equipped with deodorizing or disinfecting media to treat the gas overflowing from the garbage bag inside the recycling bin 1.

[0023] In one embodiment, a rotating mechanism is mounted on the upper side of the recycling bin 1. The rotating mechanism includes: a transmission disk 13, which is fixedly mounted on the upper side of the recycling bin 1. The transmission disk 13 has two centrally symmetrically distributed spiral grooves 131, which are vortex grooves; and a rotating rod 132, the middle of which is driven and mounted to the output end of the first servo motor 11. A support rod 133 is assembled to the end of the rotating rod 132 and slidably assembled inside the rotary groove 131. A traction hook 12 is fixedly installed at the lower end of the support rod 133. The support rod 133 is slidably assembled to the lower side of the rotating rod 132.

[0024] The lower end of the rotating rod 132 is provided with a sliding groove 1321, and the upper end of the support rod 133 is fixedly equipped with a slider 1322 that is slidably connected to the sliding groove 1321. An angle brace 1323 is installed between the support rod 133 and the slider 1322. The angle brace 1323 can increase the connection strength between the support rod 133 and the slider 1322. The sliding groove 1321 and the slider 1322 can provide stable movement for the support rod 133, prevent the support rod 133 from rotating, and also provide the support rod 133 with a movement path and movement range.

[0025] When the first servo motor 11 is started, it can drive the rotating rod 132 to rotate, thereby causing the support rod 133 to move along the vortex-shaped groove 131. The traction hooks 12 on both sides can move along the vortex-shaped groove 131 and rotate continuously along the shaft of the first servo motor 11, and come together with each other. In this way, the two hanging ears of the garbage bag can be driven to rotate along the shaft of the first servo motor 11 and come together with each other, thereby causing the opening of the garbage bag to rotate and close, forming a shape similar to a goose neck.

[0026] In one embodiment, a door 16 is hinged to the front of the recycling bin 1, and a movable storage box 161 is slidably fitted inside the recycling bin 1, which can hold garbage bags. A ramp 162 is fixedly installed on the lower side of the recycling bin 1; the ramp 162 facilitates the sliding of the storage box 161 into the door 16.

[0027] The upper side of the recycling bin 1 is equipped with a dispensing sealing door 17. The dispensing sealing door 17 is slidably and sealingly mounted on the recycling bin 1. The upper side of the recycling bin 1 is equipped with a drive mechanism, which includes a second servo motor 171, which is fixedly installed inside the recycling bin 1. The rotating shaft 172 is rotatably installed inside the recycling bin 1 and is driven by the output end of the second servo motor 171. The rotating shaft 172 is connected to the delivery sealing door 17. A gear 173 is fixedly installed in the middle of the rotating shaft 172, and the delivery sealing door 17 is fixedly installed on the rack 174 that meshes with the gear 173.

[0028] The working principle of the embodiments is explained in detail below: When using this equipment to assemble garbage bags into recycling bin 1, first open the bin door 16 and pull the storage bin 161 out of recycling bin 1. Then, place the new garbage bag into the storage bin 161, fold the opening of the garbage bag upwards and place it over the upper edge of the storage bin 161. After that, push the storage bin 161 back into recycling bin 1 along the inclined platform 162 and close the bin door 16. At this time, the opening of the garbage bag is open, and the two pressure plates 14 are located inside the garbage bag to support the bag opening. Then, hook the hanging ears on both sides of the garbage bag onto the corresponding traction hooks 12. The anti-slip grooves 15 on the traction hooks 12 can effectively prevent the hanging ears from slipping off during subsequent rotation.

[0029] When medical waste needs to be disposed of, the second servo motor 171 starts, driving the rotating shaft 172 to rotate. The gear 173 on the rotating shaft 172 meshes with the rack 174, thereby driving the disposal sealing door 17 to slide upward and open. After disposal, the second servo motor 171 reverses, and the disposal sealing door 17 slides downward and closes, achieving the sealing of the recycling bin 1 and preventing the leakage of odors and harmful gases. As medical waste is continuously added, when the garbage bag is about three-quarters full, the first servo motor 11 starts to work. Its output end drives the rotating rod 132 to rotate. The support rod 133 slides along the vortex groove 131 on the transmission disk 13 under the drive of the rotating rod 132. Due to the vortex design of the groove 131, while the support rod 133 rotates around the central axis of the first servo motor 11, it will gradually move towards the center through the slider 1322 sliding in the groove 1321 of the rotating rod 132, thereby driving the traction hook 12 to rotate and move closer to each other, twisting and closing the garbage bag opening. During this process, as the opening of the garbage bag closes, the two pressure plates 14 will rotate upwards and detach from the garbage bag. After the twist is completed, medical staff open the door 16 and pull out the storage box 161. At this time, the opening of the garbage bag is in a twisted state, and medical staff can directly use the strapping to quickly tie a gooseneck knot at the twist, avoiding the risks that may be caused by manual twisting.
