Description

Technical Field

[0001] This utility model relates to a sharps box, specifically a novel compression-type medical sharps box. Background Technology

[0002] Sharps containers are used to collect disposable needles, suture needles, and other sharp instruments, as well as disposable medical equipment such as blood transfusion sets. They are collected and incinerated 24 hours after use. Currently, hospitals across the country use sharps containers to hold discarded sharps, especially in infusion rooms and various clinical wards, where their usage is very high. However, existing sharps containers have several drawbacks. Because sharps vary in length and size, and cannot be properly arranged during placement, the container's capacity is not fully utilized, increasing the frequency of replacements and clinical costs. Furthermore, the small opening of the container, lacking any protective barrier, leads to spillage and contamination, and even puncture wounds. The manual opening and closing of the container adds to the workload and reduces efficiency. Due to the heavy workload and time constraints of medical staff, the opening may not be closed promptly, which not only violates medical regulations but also increases the risk of sharps falling out, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a novel compression-type medical instrument box to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel compression medical sharps box, comprising a cylindrical body and a cover snapped onto the port of the cylindrical body, wherein a rotating part is rotatably provided on the end face of the cover to maintain a predetermined angle of movement; A rotating shaft is fixedly installed in the center of the cylinder, and a stop block is fixedly installed between the rotating shaft and the inner wall of the cylinder. The rotating shaft is a hollow structure, and a rotating rod is rotatably installed in the hollow structure. A lever plate with the same specifications as the baffle is fixedly installed on the rotating rod. The rotating rod passes through the through hole opened in the center of the cover and the rotating part, and is flush with the end face of the rotating part; The end face of the rotating rod is provided with a plug hole; It also includes a crank rocker arm that can be inserted into the insertion hole and drive the rotating rod to rotate synchronously with it.

[0005] Preferably, the upper surface of the cap is provided with a through hole, and the rotating part is provided with a thoroughly penetrating funnel hole; One end of the funnel-shaped hole is wide, and the other end is narrow, with the narrow opening having the same specifications as the through hole.

[0006] Preferably, the end face of the rotating part facing the sealing cover is provided with an arc-shaped groove, and an equidistant spring is provided in the arc-shaped groove; The cover is fixedly provided with a limiting part that extends into the arc-shaped compartment and abuts against the end of the equidistant spring; In the default state of the equidistant spring, the limiting part on the side of the equidistant spring maintains a predetermined distance of one space from the inner wall of the arc-shaped compartment, and the funnel hole is offset from the through hole.

[0007] Preferably, the outer wall of the rotating part is fixedly provided with a protrusion.

[0008] Preferably, the outer wall of the cap facing the cylinder is fixedly provided with a centrally distributed limiting sleeve through which the rotating rod passes; The limiting sleeve is slidably provided with a first ratchet that slides along the axial direction, and the end face of the first ratchet is symmetrically provided with two teeth. A second ratchet is fixedly installed on the rotating rod, and a tooth is fixedly provided on the end face of the second ratchet; And after the dial rotates to a predetermined angle, the first ratchet engages and locks with the second ratchet.

[0009] Preferably, the first tooth on the first ratchet facing the rotation direction of the lever and engaging with the first ratchet is an arc-shaped surface.

[0010] Preferably, the cylinder has a mounting hole, and a transparent window is fixedly embedded in the mounting hole, with scale lines provided on the transparent window.

[0011] Preferably, a retaining plate is provided on the end face of the cover, and the retaining plate is located in the movable groove opened on the side of the rotating part.

[0012] Preferably, a locking groove is provided on the side of the rotating part, and an arc-shaped ring is fixedly provided between the locking groove and the movable groove; The card plate can pass over the arc-shaped ring and be inserted into the locking groove so that the cover and the rotating part are locked in a circumferential fit.

[0013] In the above technical solution, the novel compression-type medical sharps box provided by this utility model has the following beneficial effects: The design adopts a funnel-shaped opening, with one end being wide and the other end being narrow. The narrow opening connects to the through hole on the cap, allowing waste to enter through the wide opening and then through the narrow opening. This solves the problems of traditional boxes having a small opening, lacking protection, and easily causing spillage and contamination from sharp objects, or even puncture wounds.

[0014] The design of the crank rocker arm being inserted into the rotating rod drives the rotating rod to rotate, causing the deflector plate to approach the baffle plate, thereby compressing the waste put into the internal space of the cylinder, reducing the gaps between the put-in waste, and avoiding the waste of storage space caused by excessive gaps between the put-in waste.

[0015] The device employs a crank-rocker and rotary rod plug-in design, where the crank-rocker acts as a key. The rotary rod can only be used when the crank-rocker is inserted, increasing the safety of the device.

[0016] The embodiment employs a locking design, which means that when the dial plate squeezes the already inserted waste into the predetermined space, the first and second ratchet teeth will engage and lock, thereby locking the dial plate and ensuring that the space squeezed out by the dial plate is maintained.

[0017] The added equidistant springs can automatically reset and separate when the rotating part rotates to the point where the funnel hole and the through hole are connected, thus making the funnel hole and the through hole no longer connected, which facilitates clinical operation.

[0018] The added transparent window allows nurses to directly observe the state of the waste being fed into the cylinder, thus determining whether to perform the lever operation.

[0019] When the cylinder is full of waste, the rotating part is driven to rotate, that is, the funnel hole moves away from the through hole. This allows the clamping plate to pass over the arc-shaped ring and enter the locking groove. At this time, the rotating part will be locked and cannot rotate. This prevents the rotating part from being accidentally triggered to rotate during the transfer process, that is, the funnel hole moves closer to the through hole, which would cause the funnel hole and the through hole to connect and cause accidental leakage of waste.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-7 As shown, a novel compression-type medical sharps kit includes: Example 1

[0025] This example aims to compress waste materials placed inside the cylinder 1, reducing the gaps between the waste materials and preventing wasted storage space due to excessively large gaps. The detailed disclosed structure includes a cylinder 1 and a cover 2 snapped onto the port of the cylinder 1. A rotating part 3, which maintains a predetermined angle of movement, is rotatably mounted on the end face of the cover 2. A rotating shaft 4 is centrally fixed inside the cylinder 1, and a baffle 41 is fixed between the rotating shaft 4 and the inner wall of the cylinder 1. The rotating shaft 4 is a hollow structure, and a rotating rod 6 is rotatably mounted circumferentially within this hollow structure. A lever 61, matching the specifications of the baffle 5, is fixedly mounted on the rotating rod 6. The rotating rod 6 passes through a through hole in the center of the cover 2 and the rotating part 3, and is flush with the end face of the rotating part 3. Furthermore, an insertion hole 64 is provided on the end face of the rotating rod 6 on the rotating part 3. A crank rocker arm 7 can be inserted into the insertion hole 64, driving the rotating rod 6 to rotate synchronously.

[0026] In summary, the design of the crank-rocker 7 being inserted into the rotating rod 6 drives the rotating rod 6 to rotate, causing the paddle plate 61 to approach the baffle 41, thereby compressing the waste material put into the internal space of the cylinder 1. Furthermore, the design of the crank-rocker 7 being inserted into the rotating rod 6, i.e., the crank-rocker 7 acting as a key, increases the safety of the device by allowing the rotating rod 6 to be used only when the crank-rocker 7 is inserted. Example 2

[0027] This embodiment aims to solve the problems of traditional boxes having small openings, lacking protective measures, and easily causing spillage and contamination of sharp objects, or even puncture wounds. The detailed structure includes a through hole 21 on the upper surface of the cap 2 and a fully penetrating funnel hole 31 on the rotating part 3. Furthermore, one end of the funnel hole 31 is wide, and the other end is narrow, with the narrow end matching the specifications of the through hole 21.

[0028] In summary, the design of the funnel hole 31 is adopted. One end of the funnel hole 31 is a wide opening and the other end is a narrow opening. The narrow opening is connected to the through hole 21 on the cover 2, so that the waste is put in through the wide opening and then through the narrow opening. By expanding the input port, the waste is prevented from accidentally falling in during the feeding process. Example 3

[0029] Based on Embodiment 1, this embodiment has an arc-shaped groove on the end face of the rotating part 3 facing the cover 2, and an equidistant spring 8 is provided in the arc-shaped groove. A limiting part 22 is fixedly provided on the cover 2, extending into the arc-shaped compartment and abutting against the end of the equidistant spring 8. Furthermore, in the default state of the equidistant spring 8, the limiting part 22 maintains a predetermined distance of space 1 from the inner wall of the arc-shaped compartment on the side opposite to the equidistant spring 8, and the funnel hole 31 is offset from the through hole 21.

[0030] Specifically, the added equidistant spring 8 can automatically reset and separate when the rotating part 3 rotates to the point where the funnel hole 31 and the through hole 21 are connected, thereby making the funnel hole 31 and the through hole 21 no longer connected, which is convenient for clinical operation. Example 4

[0031] Based on Embodiment 1, this embodiment features a centrally located limiting sleeve 24 fixedly disposed on the outer wall of the cap 2 facing the cylinder 1, through which the rotating rod 6 passes. A first ratchet 241, which slides axially, is mounted on the limiting sleeve 24, with two symmetrically arranged teeth on its end face. A second ratchet 62 is fixedly mounted on the rotating rod 6, with one tooth fixedly arranged on its end face. Furthermore, when the lever 61 rotates a predetermined angle, the first ratchet 241 engages and locks with the second ratchet 62.

[0032] It should be noted that the first tooth on the first ratchet 241 facing the rotation direction of the lever 61 and engaging with the first ratchet 241 is an arc-shaped surface 242.

[0033] Specifically, in this embodiment, the first ratchet 241 and the second ratchet 62 may have multiple teeth, but only the first ratchet 241 is allowed to rotate clockwise, i.e., the lever 61 moves closer to the baffle 41. When the lever 61 moves away from the baffle 41, it is locked. (Combined with...) Figure 5 It can be seen that, during the counterclockwise process, the first ratchet 241 has a straight surface, which will be blocked by the straight surface of the second ratchet 62, thus preventing it from passing.

[0034] In the second embodiment, when the first ratchet 241 and the second ratchet 62 are aligned, as the first ratchet 241 passes over the arc surface 242 and enters between the two teeth of the second ratchet 62, the second ratchet 62 will slide in the limiting sleeve 24.

[0035] Therefore, when the lever 61 squeezes the waste that has been put in into the predetermined space, the first ratchet 241 and the second ratchet 62 will engage and lock, thereby locking the lever 61 and ensuring that the space squeezed out by the lever 61 is maintained. Example 5

[0036] Based on Embodiment 1, this example includes an installation hole on the cylinder 1, with a transparent window 9 fixedly embedded within the hole. The transparent window 9 has graduated lines. The added transparent window 9 allows nurses to directly observe the state of the waste being fed into the cylinder 1, thereby determining whether to activate the lever 61. Example 6

[0037] Based on Embodiment 1, this example includes a retaining plate 25 on the end face of the cover 2, located within the movable groove 33 on the side of the rotating part 3. A locking groove 34 is formed on the side of the rotating part 3, and an arc-shaped ring 35 is fixedly disposed between the locking groove 34 and the movable groove 33. Furthermore, the retaining plate 25 can pass over the arc-shaped ring 35 and engage with the locking groove 34, thereby locking the cover 2 and the rotating part 3 in a circumferential fit.

[0038] Specifically, such as Figure 1 As shown, when the inside of the cylinder 1 is full of waste, by driving the rotating part 3 to rotate, that is, the funnel hole 31 moves away from the through hole 21, the clamping plate 25 can pass over the arc-shaped ring 35 and enter the locking groove 34. At this time, the rotating part 3 will be locked and cannot rotate, thereby avoiding the situation where the rotating part 3 is accidentally triggered to rotate during the transfer process, that is, the funnel hole 31 moves closer to the through hole 21, so that the funnel hole 31 and the through hole 21 are connected, causing the accidental leakage of waste.

[0039] It should be noted that the outer wall of the rotating part 3 in the embodiment is fixedly provided with a protrusion 32, which, in conjunction with Figure 1 and Figure 2 As shown, the added protrusion 32 makes it easier for the nurse to push the rotating part 3 to rotate, so that one hand holds the cylinder 1 and the thumb pushes the protrusion 32 to make the rotating part 3 rotate until it reaches the limit angle of rotation, that is, the narrow opening of the funnel hole 31 connects with the through hole 21 on the cap 2.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
