Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment technology, specifically to a medical waste bag. Background Technology

[0002] In a medical setting, the proper collection and disposal of medical waste is crucial. Traditional medical waste bags present several problems. Firstly, their sealing methods are relatively simple, typically using ordinary ties or adhesive seals. Ties require medical staff or workers to carry them and manually tie them, a cumbersome process with poor sealing results, easily leading to leakage and increasing the risk of environmental pollution and pathogen transmission. Adhesive seals, on the other hand, may crack due to the weight, shape, or storage environment of the medical waste. Secondly, there is a lack of clear indicators for determining the fullness of medical waste bags. Medical staff or workers struggle to quickly and accurately assess whether a bag is full, leading to either premature replacement without fully utilizing the bag's space, resulting in resource waste, or overfilling, increasing sealing difficulty and leakage risk. Furthermore, during medical waste disposal, especially during special periods such as pandemics, reducing the risk of airborne droplet transmission and lowering occupational respiratory exposure risks for workers becomes an urgent issue to address.

[0003] Therefore, developing a medical waste bag with a convenient and efficient sealing structure that can effectively reduce the risk of transmission is of great practical significance. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems and provide a medical waste bag. To achieve the above objective, this utility model adopts the following technical solution:

[0005] A medical waste bag includes a main body with several sealing components. Each sealing component includes a fixing rope and a knob. The two ends of the fixing rope are fixed to the knob. The knob includes a base, a rotating platform, a rotating ring, and a turntable. The bottom of the base is fixed to the main body. The rotating ring is fitted onto the rotating platform. A first ratchet is provided on the outer side of the top of the rotating platform, and a second ratchet is provided on the inner side of the rotating ring. The first and second ratchets mesh. A groove is provided in the middle of the rotating platform, and a spring is provided in the groove. Several side posts are evenly distributed on the outer side of the rotating ring, and a central post is provided on the top of the spring. The turntable is fixed to the top of the side posts and the central post.

[0006] As an improvement, the side column is provided with fixing holes, and the two ends of the fixing rope pass through the fixing holes and are fixed to the knob.

[0007] As an improvement, the top of the rotary table is provided with a limiting plate, the outer diameter of which is larger than the inner diameter of the rotating ring.

[0008] As an improvement, the thickness of the rotary table is greater than the thickness of the rotating ring.

[0009] As an improvement, the sealing assembly also includes a limiting ring, which is fixed to the waste bag body and is located on both sides of the knob. The two ends of the fixing rope pass through the limiting ring.

[0010] As an improvement, the sealing assembly includes a first sealing assembly, a second sealing assembly, and a third sealing assembly. The first sealing assembly is located at 3 / 4 of the length of the waste bag body, the second sealing assembly is located at 1 / 2 of the length of the waste bag body, and the third sealing assembly is located at 1 / 4 of the length of the waste bag body.

[0011] The advantages of this utility model are:

[0012] 1. This utility model achieves sealing by tightening the fixing rope with a rotating knob, which is simple and quick to operate, eliminating the need for carrying additional bags and tying ropes, thus saving time and labor costs. At the same time, the design of releasing the seal by pressing the turntable greatly improves the convenience of opening.

[0013] 2. This utility model sets sealing components at 1 / 4, 1 / 2, and 3 / 4 of the length of the waste bag body. When the medical waste in the waste bag is filled to the corresponding position, the position of the fixing rope can be observed to quickly determine whether the waste bag is full, which facilitates timely cleaning and packaging, improves the efficiency of medical waste treatment, and avoids overfilling or underutilization of the waste bag space.

[0014] 3. The excellent sealing effect of this utility model can effectively reduce the risk of airborne droplet transmission during the collection, transportation and storage of medical waste, reduce the possibility of occupational respiratory exposure for staff, and provide strong protection for the safety of the medical environment.

[0026] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0027] Example 1

[0028] This embodiment discloses a medical waste bag.

[0029] like Figures 1 to 4 As shown, this embodiment includes a waste bag body 1, and a plurality of sealing components are provided on the waste bag body 1. The sealing components include a fixing rope 2 and a knob 3. The two ends of the fixing rope 2 are fixed to the knob 3. The knob 3 includes a base 4, a rotating platform 5, a rotating ring 6, and a turntable 7. The bottom of the base 4 is fixed to the waste bag body 1. The rotating ring 6 is sleeved on the rotating platform 5. A first ratchet 8 is provided on the outer side of the top of the rotating platform 5, and a second ratchet 9 is provided on the inner side of the rotating ring 6. The first ratchet 8 and the second ratchet 9 mesh. A groove 10 is provided in the middle of the rotating platform 5. A spring 11 is provided in the groove 10. A plurality of side posts 12 are evenly provided on the outer side of the rotating ring 6. A central post 13 is provided on the top of the spring 11. The turntable 7 is fixed on the top of the side posts 12 and the central post 13.

[0030] The two ends of the fixing rope 2 are fixed to the knob 3. The knob 3 serves as an operating component, controlling the tightening and loosening of the fixing rope 2 by rotation. When the knob 3 is rotated, the fixing rope 2 is wound or unwound, thereby sealing and unsealing the waste bag. This embodiment has four side posts 12 and three sealing components.

[0031] The base 4 is firmly fixed to the waste bag body 1, providing a stable support foundation for the entire knob 3 structure, ensuring that the knob 3 will not detach from or shake when operating, thus guaranteeing the stability of operation.

[0032] The rotating ring 6 is fitted onto the rotating platform 5, and the two are engaged with each other by the first ratchet 8 and the second ratchet 9. This design ensures that when the rotating platform 5 rotates in the forward direction, the rotating ring 6 will rotate synchronously with the rotating platform 5 due to the engagement of the ratchet. When the rotating platform 5 attempts to rotate in the reverse direction, the one-way locking characteristic of the ratchet comes into play, preventing the rotating ring 6 from rotating in the reverse direction, thus achieving the one-way tightening function of the fixing rope 2 and ensuring that it will not loosen after sealing.

[0033] When it is necessary to unseal, press the turntable 7. At this time, the turntable 7 drives the side column 12 and the middle column 13 to move downward, compressing the spring 11. At the same time, the first ratchet 8 and the second ratchet 9 are misaligned, releasing the locking relationship between the rotating table 5 and the rotating ring 6. The rotating table 5 can then rotate in the opposite direction, releasing the fixing rope 2 and completing the unsealing operation. In this embodiment, the spring 11 is in a compressed state.

[0034] The side column 12 is provided with a fixing hole 14, and the two ends of the fixing rope 2 pass through the fixing hole 14 and are fixed to the knob 3.

[0035] The top of the rotating table 5 is equipped with a limiting plate, the outer diameter of which is larger than the inner diameter of the rotating ring 6.

[0036] The limiting disc is mainly used to prevent the rotating ring 6 from coming off upwards during rotation. In actual use of the knob 3, when the user rotates the turntable 7, causing the rotating ring 6 to rotate around the rotating platform 5, the rotating ring 6 may have an upward displacement tendency due to uneven force or improper operation.

[0037] The thickness of the rotating platform 5 is greater than the thickness of the rotating ring 6.

[0038] The thickness of the rotating platform 5 provides ample space for the rotating ring 6 to move downwards. When the rotating disk 7 is pressed down, the rotating ring 6 will not be blocked due to insufficient thickness of the rotating platform 5 during its downward movement. This allows the first ratchet 8 and the second ratchet 9 to disengage smoothly, ensuring that the user can easily rotate the rotating disk 7 in the opposite direction to untie the fixing rope 2 and complete the opening operation of the medical waste bag. This ensures the smooth operation of the sealing assembly during the opening process.

[0039] The sealing assembly also includes a limiting ring 15, which is fixed on the waste bag body 1. The limiting ring 15 is located on both sides of the knob 3, and the two ends of the fixing rope 2 pass through the limiting ring 15.

[0040] The function of the limiting ring 15 is to fix the rope 2 during the tightening process and prevent it from shifting to the left or right or getting tangled due to factors such as uneven rotation direction and force of the knob 3, which would affect the sealing effect.

[0041] The sealing assembly includes a first sealing assembly 16, a second sealing assembly 17, and a third sealing assembly 18. The first sealing assembly 16 is located at 13 / 4 of the length of the waste bag body, the second sealing assembly 17 is located at 11 / 2 of the length of the waste bag body, and the third sealing assembly 18 is located at 11 / 4 of the length of the waste bag body.

[0042] The sealing components at different locations and their corresponding fixing ropes 2 serve as intuitive indicators of full load. During daily work, staff can quickly determine the waste filling status of the waste bag simply by observing the position of the fixing ropes 2, without needing to open the bag for inspection. This greatly improves work efficiency, avoids overfilling or premature bag replacement, and ensures the efficiency and safety of the medical waste disposal process.

[0043] When sealing medical waste bags, the user rotates the turntable 7 on knob 3. Since turntable 7 is connected to side posts 12 and center posts 13, rotating turntable 7 causes rotating ring 6 to rotate synchronously. Because the second ratchet 9 inside rotating ring 6 engages with the first ratchet 8 on the outer side of the top of rotating platform 5, the rotation of rotating ring 6 causes rotating platform 5 to rotate. During the rotation of rotating platform 5, the fixing rope 2 fixed to rotating platform 5 is gradually wound and tightened, thus sealing the waste bag. Due to the one-way locking effect of the ratchet structure, fixing rope 2 will not automatically loosen after tightening, ensuring the stability of the seal.

[0044] When it is necessary to open the sealed medical waste bag, the user presses the turntable 7. At this time, the spring 11 is compressed, causing the central column 13 and the side column 12 to move downwards, thus disengaging the first ratchet 8 and the second ratchet 9 and releasing the one-way locking relationship between the rotating platform 5 and the rotating ring 6. At this time, the user can rotate the turntable 7 in the opposite direction, causing the rotating platform 5 to rotate in the opposite direction, loosening the fixing rope 2, and thus unlocking the seal.

[0045] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model should be covered within the scope of this utility model.
