Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a sharps storage box. Background Technology
[0002] A sharps container is a medical device used to collect medical waste, mainly including syringes, small glass items, blades, needles, and other sharps. Existing sharps containers have a feeding port on the top, through which medical staff put the sharps into the container. To prevent the spread of germs from inside the container to the outside, the feeding port is usually set to be small. However, due to the small size of the feeding port, it is not convenient to put the sharps in. The sharps may fall to the ground during the process, requiring medical staff to pick them up and put them back into the container. In this process, medical staff are at risk of pricking their fingers.
[0003] To address the aforementioned shortcomings, a funnel-shaped feeding section is typically installed on the feeding port. The larger opening of the feeding section is located at the top, which enlarges the feeding entrance to facilitate the feeding of sharps. When the collected sharps reach three-quarters of the sharps container's capacity, collection needs to be stopped, the feeding section is removed, and the sharps container is sealed with an end cap to prevent recyclables from falling out of the feeding port during processing. The recyclables are then collected by medical waste disposal units. However, existing sharps containers still have some shortcomings: the feeding section needs to be recycled separately. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a sharps storage box that not only expands the feeding inlet through the feeding section, but also seals the box directly through the feeding section after storage, without the need for separate recycling of the feeding section.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a sharps storage box, including a box body and a feeding part disposed on the box body. The feeding part is funnel-shaped, and a feeding port is opened in the middle of the upper side of the box body. A connecting cylinder for sliding cooperation with the feeding port is provided on the lower side of the feeding part. A fixing strip is provided on the outer circular surface of the feeding part, and a limiting structure is provided at the free end of the fixing strip. The feeding part is elastic. After storage, the feeding part is folded into a block shape and moved downwards until its upper side is aligned with the upper side of the box body. The limiting structure limits the folded feeding part.
[0006] The working principle of this solution is as follows: When the sharps container is not in use, the feeding section is folded up to align with the top of the container and is limited by a limiting structure. When the sharps container is needed to collect discarded medical sharps, the limiting structure is moved so that it no longer limits the feeding section. Because the feeding section is elastic, it returns to a funnel shape when the limiting structure no longer limits it. The connecting cylinder located on the lower side of the feeding section is connected to the feeding port, so discarded medical sharps can be put into the sharps container through the upper end of the feeding section, i.e., the large opening end. When the collection volume reaches the upper limit of the range specified by the sharps container, feeding stops. Then, the opposite sides of the feeding section are folded inward, and then the other two sides of the feeding section are folded inward, folding it into a block shape in sequence. The block is then moved downward until the upper side of the feeding section is aligned with the top of the container, sealing the feeding port. Finally, the fixing strip passes through the upper side of the folded feeding section and is limited by the limiting structure.
[0007] Compared with existing technologies, the advantages of this solution are as follows: In the initial state, the feeding section is in a retracted state. When in use, the limiting position of the feeding section is removed, allowing it to return to a funnel shape and expanding the feeding inlet. This facilitates the collection of discarded medical sharps and prevents sharps from falling out of the box due to a small feeding opening. After use, the feeding section is folded and limited. The folded feeding section can seal the feeding opening on the box, eliminating the need to remove the feeding section from the box and seal the box by covering it with an end cap. Moreover, the feeding section can be recycled simultaneously without any additional processing.
[0008] In a preferred embodiment of this utility model, the upper side of the box body has a groove, and a locking post is provided on the side of the groove near the feeding part. The limiting structure includes a connecting block provided on one side of the fixing strip, and the connecting block is provided with a through hole for the locking post to pass through.
[0009] The beneficial effects of this solution are as follows: After folding the feeding section and moving it downwards until its upper side is aligned with the upper side of the box, the fixing strip passes through the upper side of the folded feeding section. By passing the locking post through the through hole, the folded feeding section is limited. At this time, the feeding section covers the feeding port, thereby sealing the box. The locking post is set on the side close to the feeding section. Since the feeding section is elastic, it tends to fold outwards after being folded, which drives the connecting block to move towards the feeding section, thereby making the connection between the connecting block and the locking post more stable.
[0010] In a preferred embodiment of this utility model, the upper middle part of the box body is provided with a receiving groove for accommodating the folded feeding part, and the area of the receiving groove is larger than the area of the feeding port.
[0011] The beneficial effects of this solution are as follows: Since the cross-sectional area of the folded feeding section is larger than that of the connecting cylinder, the folded feeding section can be moved downward into the receiving groove by setting the receiving groove until the upper side of the feeding section is flush with the upper side of the box. This not only makes it more aesthetically pleasing, but also allows the locking post and the connecting block to be connected smoothly, which facilitates the limiting of the folded feeding section.
[0012] In a preferred embodiment of this utility model, the fixing strip is disposed on the lower side of the feeding section.
[0013] The advantages of this solution are: compared to placing the fixing strip in the middle or upper part of the feeding section, placing the fixing strip on the lower part of the feeding section will not affect the folding of the feeding section, and the folding sequence can be freely selected.
[0014] In a preferred embodiment of this utility model, two fixing strips are arranged radially offset along the feeding part, and the free ends of the two fixing strips are respectively provided with limiting structures. Two grooves are arranged radially offset along the box body, and the positions of the two grooves correspond to the positions of the two connecting blocks respectively.
[0015] The beneficial effects of this solution are: two fixing strips are arranged radially along the feeding section, and the two fixing strips are staggered, which can further strengthen the limiting of the feeding section after folding, and prevent the feeding section from automatically returning to the funnel shape and no longer sealing the box when the sharps storage box is no longer needed or after storage.
[0016] In a preferred embodiment of the present invention, a limiting block is provided at the bottom of the connecting cylinder along its radial direction, and the upper side of the limiting block can abut against the top wall inside the box.
[0017] The beneficial effects of this solution are: the limiting block can limit the connecting cylinder and the feeding part in the vertical direction, preventing the connecting cylinder from separating from the box body after the limiting of the feeding part is removed, thus affecting the storage efficiency.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only for explaining the present invention and do not limit the scope of protection of the present invention.
[0023] The terms "first," "second," etc., used in the specification, claims, and embodiments of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.
[0024] The present invention will be further described in detail below through preferred embodiments: The reference numerals in the accompanying drawings include: box body 1, feeding port 101, receiving groove 102, groove 103, feeding part 2, connecting cylinder 3, fixing strip 4, connecting block 5, through hole 501, locking post 6, and limiting block 7.
[0025] As attached Figure 1 and attached Figure 3 As shown: The sharps storage box of this embodiment includes a box body 1. The upper middle part of the box body 1 has a feeding port 101 communicating with its inner cavity. The upper middle part of the box body 1 has a receiving groove 102 communicating with the feeding port 101. In this embodiment, the receiving groove 102 is square and its area is larger than the area of the feeding port 101. The upper side of the box body 1 has a groove 103. Two grooves 103 are arranged radially offset along the box body 1. The two grooves 103 are respectively provided with a retaining post 6 on the side that is close to each other. A gap is left between the front side of each retaining post 6 and the side wall of the groove 103.
[0026] As attached Figures 1-3 As shown: A feeding part 2 is provided above the box body 1. The feeding part 2 is funnel-shaped, including a large opening end and a small opening end. The diameter of the large opening end is larger than the diameter of the feeding port 101. The feeding part 2 is elastic. In this embodiment, the feeding part 2 is preferably medical elastic plastic. A fixing strip 4 is provided on the outer circular surface of the feeding part 2. In this embodiment, both the feeding part 2 and the fixing strip 4 are made of medical elastic plastic. Two fixing strips 4 are arranged radially offset along the feeding part 2. Both fixing strips 4 are arranged on the lower side of the feeding part 2. The free ends of the two fixing strips 4 are respectively provided with limiting structures. The limiting structures include connecting blocks 5 arranged on the side of the fixing strip 4 away from the feeding part 2. The connecting blocks 5 are provided with through holes 501 for the pin 6 to pass through. The positions of the two grooves 103 correspond to the positions of the two connecting blocks 5 respectively.
[0027] The feeding part 2 is provided with a connecting cylinder 3 on its lower side for sliding cooperation with the feeding port 101. The outer diameter of the connecting cylinder 3 is the same as the outer diameter of the small opening end of the feeding part 2. The bottom of the connecting cylinder 3 is provided with a limiting block 7 along its radial direction. The upper side of the limiting block 7 can abut against the top wall inside the box body 1.
[0028] Working principle When the sharps container is not in use, the feeding section 2 is folded into a block shape and located in the receiving groove 102, and is limited by two fixing strips 4. At this time, the two locking posts 6 located in the groove 103 pass through the through hole 501 and are connected to the connecting block 5. When the sharps container needs to be used to collect discarded medical sharps, the two fixing strips 4 are stretched in the direction away from each other, so that the connecting block 5 is separated from the locking posts 6. At this time, the fixing strips 4 no longer limit the feeding section 2, and the feeding section 2 returns to the funnel shape. Discarded medical sharps can be put into the container 1 from the large opening end of the feeding section 2. When the collection volume reaches the upper limit specified by the sharps storage box, the feeding is stopped. Then, the feeding part 2 is folded into a block shape. The specific steps are as follows: First, the two opposite sides of the feeding part 2 along the front and rear directions are folded inward, so that the curved surfaces on the front and rear sides are pressed towards the central axis. This step flattens the feeding part 2, forming a flat structure extending in the left and right directions. Then, the remaining left and right sides are folded inward in the same way. At this time, the sides in all four directions are compressed to the vicinity of the central axis. The circular upper surface of the feeding part 2 gradually deforms into a quadrilateral. After the feeding part 2 is folded, it is moved downward into the receiving groove 102. At this time, the upper side of the feeding part 2 is aligned with the upper side of the box body 1, and the lower side of the feeding part 2 is attached to the bottom wall of the receiving groove 102, covering the feeding port 101 and sealing the box body 1. Then, the two fixing strips 4 are passed through the upper side of the folded feeding part 2 respectively, and the locking post 6 is re-passed through the through hole 501, so that the connecting block 5 is connected to the locking post 6, thus limiting the folded feeding part 2.
