[0043] Figure 4 for Figure 1 A partial enlarged view of . DETAILED DESCRIPTION

[0044] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0045] Certain words are used in the specification and claims to refer to specific components. Those with ordinary knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

[0046] See also Figures 1 to 3 In some embodiments of the present invention, the medical waste storage device includes a barrel body 1, a barrel cover 2, an inner liner 3, a support plate 3p and a rope 4.

[0047] The first side s1 of the barrel cover 2 is rotatably connected to the top of the barrel body 1, for example, through a pivot r. In this embodiment, a handle 2h may be provided on the barrel cover 2, and the user may hold the handle 2h to open or close the barrel cover 2. The support plate 3p is floatingly arranged in the barrel body 1, and the inner liner 3 is supported on the upper surface of the support plate 3p, which is used to contain medical waste, and the inner liner 3 can be taken out of the barrel body 1 for direct dumping. A spring s is arranged between the support plate 3p and the inner wall of the barrel body 1, and an opening 10 is opened on the side wall of the barrel body 1 corresponding to the bottom of the first side s1. The rope 4 is passed through the opening 10, and the first end and the second end of the rope 4 are respectively connected to the barrel cover 2 and the lower surface of the support plate 3p.

[0048] Based on the above, when the barrel cover 2 is operated to be closed, the barrel cover 2 rotates and provides an upward pulling force to the rope 4 located outside the barrel body 1 (that is, the rope 4 at the first end). The opening 10 is opened at the bottom of the barrel body 1, which refers to the position of the opening 10, which is located below the lowermost end of the movable range of the support plate 3p and the inner liner 3. That is to say, the rope 4 located in the barrel body 1 passes through the opening 10 and then extends upward to connect the support plate 3p. At this time, the rope 4 (that is, the rope 4 at the second end) provides a downward pulling force to the support plate 3p, thereby driving the support plate 3p and the inner liner 3 placed thereon to move downward. The spring s is, for example, located between the support plate 3p and the inner bottom wall of the barrel body 1, and the spring s is correspondingly compressed; in other embodiments, the spring s may also be located above the support plate 3p, and the spring s is stretched when the support plate 3p moves downward, but the actual application is not limited to this. When the barrel cover 2 is opened, the barrel cover 2 releases the rope 4, which means that the rope 4 is in a relaxed state at the moment the barrel cover 2 is opened. The rope 4 further cancels the pulling force on the support plate 3p, so that the support plate 3p obtains movable space, and the support plate 3p moves upward by the restoring force of the spring s.

[0049] So, like Figure 3 As described above, when the barrel cover 2 is opened, the inner liner 3 automatically pops up from the barrel body 1, making it convenient for medical staff to take out the medical waste in the inner liner 3 for treatment; Figure 1 and Figure 2 As shown, when the barrel cover 2 is closed, the inner liner 3 can be automatically retracted downward into the barrel body 1, which will not affect the closing of the barrel cover 2. The convenience of using the medical waste storage device is improved, and medical waste is prevented from being spilled on medical staff or the surrounding environment during the treatment process, which is more hygienic and safe.

[0050] In other embodiments of the present invention, the medical waste storage device does not include a support plate (not shown in the figure), that is, the second end of the rope 4 is directly connected to the bottom of the inner liner 3, and the spring s is arranged between the inner liner 3 and the inner wall of the barrel body 1. The other structures are similar to the previous embodiment and will not be repeated here.

[0051] In a preferred embodiment, if Figure 2 As shown, the medical waste storage device also includes a pulley 11 and / or a guide member 12.

[0052] Among them, the pulley 11 is rotatably arranged on the outer wall of the barrel body 1, and the setting position of the pulley 11 is adjacent to the opening 10. The rope 4 passes through the position tangent to the outer edge of the pulley 11 to cooperate with the pulley 11, that is, the rope 4 passes through the opening 10 through the pulley 11. As described above, the two parts of the rope 4 located on the inner and outer sides of the barrel body 1 move in different directions when being pulled by the barrel cover 2. In other words, the rope 4 undergoes a direction turn at the opening 10, and the pulley 11 is located at the turning point of the rope 4, so that the rope 4 at the turning point can slide more smoothly and reduce the wear of the rope 4. In other embodiments, two positioning pieces can be arranged near the opening 10, and the two ends of the rotating shaft can be rotatably connected to the two positioning pieces respectively, and the rope 4 can cooperate with the rotating shaft to assist the turning of the rope 4 by means of the rotating shaft.

[0053] Among them, the guide member 12 is arranged at the center of the inner bottom wall of the barrel body 1. In the above-mentioned embodiment with the support plate 3p, the rope 4 is inserted into the guide member 12 and then connected to the support plate 3p, and the second end of the rope 4 is fixed to the center of the lower surface of the support plate 3p. In other words, the rope 4 between the guide member 12 and the support plate 3p extends in the vertical direction and is connected to the central part of the support plate 3p. When the rope 4 is pulled, the pulling force of the rope 4 on the support plate 3p corresponds to the central position of the support plate 3p, so that the support plate 3p can move downward more smoothly. In the above-mentioned embodiment without the support plate, the rope 4 is inserted into the guide member 12 and directly connected to the bottom center of the liner 3. The rest of the structure is similar and will not be repeated. In this embodiment, the guide member 12 can be composed of two positioning pieces and a rotating shaft. Their matching structure and function are similar to those described above and will not be repeated. The guide member 12 of this structure has the characteristics of small volume and can occupy a smaller space in the barrel body 1. In other embodiments, the guide member 12 may also be a pulley, similar to that described above, and the pulley may provide smoother guiding assistance.

[0054] It should be noted that in order to lift the inner liner 3 filled with medical waste, the above-mentioned spring s preferably has a strong restoring force. In order to prevent the restoring force of the spring s from further lifting the closed barrel cover 2, in the present embodiment, a locking member 23 is fixedly provided on the second side s2 of the barrel cover 2, and the second side s2 is preferably opposite to the first side s1. The locking member 23 is used to snap-fit ​​and fix the barrel cover 2 when it is closed on the barrel body 1, for example, snap-fit ​​and fix with the barrel body 1 or a component installed on the barrel body 1, so as to assist the barrel cover 2 in maintaining the closed state. In other embodiments, a counterweight may also be provided on the barrel cover 2 to resist the restoring force of the spring s, but the actual application is not limited to this.

[0055] In this embodiment, if Figure 2As shown, the barrel cover 2 includes a cover body 21 and an extension piece 22, a first side s1 of the cover body 21 is rotatably connected to the barrel body 1, a fixed end of the extension piece 22 is connected to the cover body 21, a free end of the extension piece 22 extends out of the cover body 21 from the first side s1, and the first end of the rope 4 is connected to the free end of the extension piece 22. In this embodiment, the free end of the extension piece 22 extends along the radial direction of the cover body 21 toward the outer side of its periphery, and the extension direction of the extension piece 22 is perpendicular to the axial direction of the rotational connection axis of the cover body 21 and the barrel body 1 (i.e., the axial direction of the pivot r). In other embodiments, the extension piece 22 can also extend in a direction inclined to the radial direction of the cover body 21, for example, when the cover body 21 is closed, the extension piece 22 can extend obliquely upward to the cover body 21, but the actual application is not limited to this. It should be noted that, since the state of the bucket cover 2 is adjustable, for the convenience of description, the upper and lower directions of the bucket cover 2 and the components installed on the bucket cover 2 mentioned in this article are all based on the state of the bucket cover 2 when it is closed (i.e. Figure 1 and Figure 2 state), which is similar to the situation of the direction of the extension piece 22 described above, and will not be described in detail below. It should be noted that, in addition to being used to cooperate with the sliding piece 24 to be described below, after the first end of the rope 4 is connected to the free end of the extension piece 22, when the bucket cover 2 switches between the open and closed states, the rope 4 can obtain a longer range of motion, and the inner liner 3 is correspondingly allowed to have a larger movement stroke, that is, the inner liner 3 can be lifted higher when the bucket cover 2 is opened, which is more conducive to medical staff to handle the medical waste therein.

[0056] Furthermore, the medical waste storage device also includes a sliding member 24 and a connecting member 25. The sliding member 24 can be slidably radially penetrated in the barrel 1. In other words, Figure 2 As shown, the barrel body 1 has a first opening Ha and a second opening Hb arranged radially, wherein when the cover body 21 is closed, the first opening Ha corresponds to the position of the first side s1 of the cover body 21, and the second opening Hb corresponds to the position of the second side s2 of the cover body 21. The sliding member 24 can slide through the first opening Ha and the second opening Hb, and the opposite first end 24a and second end 24b on the sliding member 24 are exposed from the first opening Ha and the second opening Hb respectively. In this embodiment, the two ends of the connecting member 25 are rotatably connected to the extension member 22 and the first end 24a respectively. In this embodiment, the connecting member 25 can be two strip pieces, which are respectively clamped on the opposite side surfaces of the extension member 22 and the first end 24a; in other embodiments, the connecting member 25 can also be a strip piece, and the actual application is not limited to this. Please refer to Figures 1 to 3 When the barrel cover 2 is opened, the extension member 22 drives the connecting member 25 to pivot accordingly. Figure 2For example, the connecting member 25 rotates clockwise relative to the extending member 22 and counterclockwise relative to the sliding member 24, thereby driving the sliding member 24 to slide in the second direction a2 to release the cooperation between the second end 24b and the locking member 23; when the barrel cover 2 is closed, the extending member 22 drives the connecting member 25 to pivot accordingly, so as to Figure 2 For example, the connecting member 25 rotates counterclockwise relative to the extending member 22 and rotates clockwise relative to the sliding member 24, thereby driving the sliding member 24 to slide in the first direction a1 so that the second end 24b cooperates with the locking member. The first direction a1 is a direction extending from the second end 24b to the first end 24a, and the second direction a2 is opposite to the first direction a1, that is, the first direction a1 and the second direction a2 are two opposite directions parallel to the radial direction of the barrel body 1.

[0057] In this embodiment, if Figure 4 As shown, the locking member 23 has a slit 231g extending along the side wall direction of the barrel cover 2 and opening at the lower side. The sliding member 24 has a rod portion connecting the first end 24a and the second end 24b, the width dimension of the rod portion of the sliding member 24 is smaller than the width dimension of the slit 231g, and the width dimension of the second end 24b is larger than the width dimension of the slit 231g. When the barrel cover 2 is closed, the slit 231g of the locking member 23 is inserted into the rod portion of the sliding member 24 and is laterally clamped and limited by the second end 24b. In some embodiments, the locking member 23 further has a locking groove 231c disposed adjacent to the slit 231g, and the second end 24b further has a protrusion 241 corresponding to the locking groove 231c. When the bucket cover 2 is closed, the locking groove 231c is laterally locked and limited by the protrusion 241 of the second end 24b. In other words, when the bucket cover 2 is closed, the sliding member 24 is driven to move toward the first direction a1, so that the protrusion 241 is locked in the locking groove 231c, thereby limiting the bucket cover 2. In other embodiments, the locking member 23 may also have a protrusion (not shown in the figure) near the slit 231g, and the second end 24b may have a corresponding locking groove (not shown in the figure), but the actual application is not limited thereto. In some further embodiments, the locking member 23 may further have a U-shaped lock (not shown in the figure, and it can be understood that the area below the slit 231g is a closed structure). When the barrel cover 2 is closed, the second end 24b of the sliding member 24 slides in the second direction a2 and then passes through the U-shaped lock, so that the barrel cover 2 is limited by the sliding member 24 and will not open automatically. However, the actual application is not limited to this.

[0058] In this embodiment, if Figure 4As shown, the locking member 23 also has a fixed protrusion 231 and a lock 232. The protrusion 231 can also be located above the slit 231g. In this embodiment, the lock 232 is rotatably arranged on the protrusion 231. The lock 232 is used to rotate and sleeve on the second end 24b of the sliding member 24 when the bucket cover 2 is closed. The matching structure with the protrusion / slot described above serves as a double insurance to assist the bucket cover 2 to maintain the closed state, so as to ensure the tightness of the bucket cover 2 when it is closed. In other embodiments, the lock 232 can also be sleeved with the bucket body 1 or other parts fixed to the bucket body 1; or, the locking member 23 can also have other structures that can be sleeved and fixed with the bucket body 1, which are commonly seen in the box cover structure with a lock and will not be repeated; and the actual application is not limited to this.

[0059] In the above-mentioned embodiments, the number of the inner liner 3 can be one, two or more. When the number of the inner liner 3 is one, in order to avoid the action of lifting the inner liner 3 from interfering with the sliding member 24, the side wall of the inner liner 3 can be provided with a strip groove for making way for the sliding member 24, for example, the longitudinal section of the inner liner 3 can be concave. In some embodiments of the present invention, the inner liner 3 includes a first inner liner 31, a second inner liner 32 and a support plate 3p. The rope 4 is connected to the lower surface of the support plate 3p, and the spring s is arranged between the support plate 3p and the inner wall of the barrel 1. The first inner liner 31 and the second inner liner 32 are respectively arranged on the upper surface of the support plate 3p, and the sliding member 24 is penetrated between the first inner liner 31 and the second inner liner 32, so that the sliding member 24 can slide between the first inner liner 31 and the second inner liner 32. When the support plate 3p is lifted upward, the first inner liner 31 and the second inner liner 32 are respectively driven to lift, and the two are separated by the sliding member 24 and are independent of each other, so they will not interfere with the sliding member 24. Preferably, the first liner 31 and the second liner 32 can be used to place different types of medical waste, for example, needles and syringes can be classified and stored separately. The first liner 31 and the second liner 32 can be placed directly on the support plate 3p. If necessary, the first liner 31 or the second liner 32 can be taken out of the barrel 1 for dumping, cleaning and other operations. In other embodiments, the medical waste storage device can also be configured with two sets of ropes 4 and springs s, which are respectively arranged at the bottom of the first liner 31 and the second liner 32. That is, there is no support plate 3p in this embodiment, and the first liner 31 and the second liner 32 are controlled by independent driving mechanisms to perform lifting and lowering actions separately. It can be understood that the amount of some types of medical waste is small, and the corresponding storage space (liner) can be smaller. In order to facilitate the removal of such medical waste, the corresponding liner should be lifted higher. That is to say, in the above embodiment, the movement of the two ropes 4 can be designed to be different to adapt to different liner lifting heights. When there are multiple inner containers 3, the structure may be similar to that when there are two inner containers 3. For example, when there are four inner containers 3, two inner containers may be placed on both sides of the sliding member 24, which will not be described in detail here.

[0060] In summary, the medical waste storage device provided by the present invention includes a barrel body, a barrel cover, an inner liner and a rope. The inner liner is floatingly arranged in the barrel body, and a spring is arranged between the inner liner and the inner wall of the barrel body; the first side of the barrel cover is rotatably connected to the top of the barrel body, and the barrel body is provided with an opening at the bottom corresponding to the first side, and the rope is passed through the opening, and the first end and the second end of the rope are respectively connected to the barrel cover and the bottom of the inner liner. When the barrel cover is closed, the barrel cover pulls the rope, thereby driving the inner liner to move downward; when the barrel cover is opened, the barrel cover releases the rope, and the inner liner moves upward by the restoring force of the spring.

[0061] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention.
