Description

Technical Field

[0001] The invention relates to a waste storage box, in particular to a storage box for accommodating medical waste. Background Art

[0002] Medical waste contains a large number of fungi, viruses and bacteria, and can also produce chemical toxic substances. Under the influence of airflow and wind, these harmful substances will spread and spread to the surrounding area, thus posing a serious threat to people's health. In recent years, in order to prevent nosocomial infections, a large number of disposable medical supplies have been used in clinics, becoming a new source of pollution in hospitals. After these disposable supplies become medical waste, how to collect, store and transport them is an important issue for their standardized and safe management. To this end, the Chinese utility model patent "Sharps Bucket" with patent number ZL200420012363.9 (authorization announcement number CN2719775Y) is currently widely used on the market. The sharps bucket is used to collect disposable syringes and infusion needles discarded by medical institutions such as hospitals and clinics. It includes a barrel body, a barrel cover, and a rotating opening and closing cover. The barrel body and the barrel cover are clamped together by buckles on their edges. The rotating opening and closing cover is embedded in the annular groove on the barrel cover and is fixed to it by the clamping rotating shaft at the center. However, the cover needs to be kept open during use so that the pathogens and viruses attached to the medical waste can diffuse into the air around the sharps bucket. To this end, a Chinese invention patent application with application number CN202010301455.2 (publication number CN111467558A) entitled "A Discarded Mask Disinfection Processing Machine" proposed a solution. The processing machine includes a box body and a control system; the box body includes a temporary storage bin, a heating bin and a storage bin from top to bottom; a heating device is provided inside the heating bin; the heating device is an infrared disinfection device, which includes a number of infrared light sources; after the discarded masks enter the heating bin, they are heated and disinfected by the heating device under the control of the control system, and then enter the storage bin from the first active switch and can be taken out through the outlet. After the mask is discarded, the inside of the above-mentioned processor is separated from the outside world to avoid the diffusion of harmful gases. It can be generally used in the field of medical waste storage, but it needs to consume electricity to heat and disinfect the medical waste. Firstly, it consumes a lot of energy. Secondly, it cannot be used in some places without power supply. Finally, the processor did not make further design for the storage bin. The top of the storage bin is open. When taking out, medical waste may fall out of the storage bin. If the disinfection is not thorough, harmful gases may also be released. Summary of the invention

[0003] The first technical problem to be solved by the present invention is to provide a medical waste collection box which can maximally prevent harmful gases in the collection container from spreading to the outside and can disinfect the collection container without relying on electrical energy, in response to the above-mentioned existing technical status.

[0004] The second technical problem to be solved by the present invention is to provide a medical waste storage box which can seal the container of medical waste before it is taken out in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is as follows: the medical waste storage box includes a container shell, characterized in that: the container shell includes, from top to bottom, an upper accommodating chamber and a lower accommodating chamber which are divided into relatively independent spaces by a flippable partition, and the container shell is provided with an inlet for placing waste corresponding to the upper accommodating chamber; the container shell has a disinfectant spraying chamber in the upper accommodating chamber, the disinfectant spraying chamber is connected to the upper accommodating chamber through at least one spraying channel which can guide the disinfectant, and each of the spraying channels is provided with at least one opening for the disinfectant to pass through and spray into the upper accommodating chamber, and also includes an extrusion device located outside the container shell and connected to the disinfectant spraying chamber, and driving the extrusion device can change the volume of the disinfectant spraying chamber to change the pressure in the disinfectant spraying chamber, thereby squeezing the disinfectant from the spraying channel into the upper accommodating chamber; a driving mechanism which can successively drive the partition to flip and the extrusion device is also provided outside the container shell.

[0006] Specifically, the driving mechanism is composed of a driving rod, a first elastic member connected to one end of the driving rod, and a driving box for accommodating the driving rod and the first elastic member, wherein the driving rod includes a rod body, a driving head partially exposed from the driving box, and a pulling portion, and the user can control the sliding of the rod body when operating the pulling portion, the fixed end of the first elastic member is connected to one end of the rod body facing away from the disinfectant spray chamber, and the free end of the first elastic member supports the bottom of the driving box, so that the rod body always has a tendency to squeeze the squeezing device.

[0007] In order to prevent harmful gases released when medical waste is placed on the partition from spreading to the outside, preferably, it also includes a first baffle hinged on the periphery of the input port through a first rotating shaft, and has a tendency to close the input port. The end of the first rotating shaft partially extends out of the container shell and is connected to a transmission mechanism. When the user operates the pulling part, the rod body can be driven to slide downward, and when the driving head of the driving rod triggers the transmission mechanism, the first rotating shaft can be driven to rotate, thereby realizing the rotation of the first baffle and opening the input port.

[0008] Specifically, the transmission mechanism consists of a first gear, a second gear meshing with the first gear, and a transmission bar meshing with the second gear. The first gear is connected to the end of the first rotating shaft, and the second gear is connected to the container shell. The transmission bar is embedded in the fourth slide groove of the container shell and can slide in the fourth slide groove. A transmission foot is connected to the side facing away from the container shell. The transmission foot and the transmission bar form a roughly L-shape. When the driving head contacts the transmission foot, it can drive the transmission bar to slide and transmit the relative rotation of the second gear and the first gear, thereby realizing the rotation of the first baffle and opening the input port.

[0009] In order to allow waste to fall from the upper accommodating chamber into the lower accommodating chamber, the partition is flipably arranged on the inner wall of the container shell through a second rotating shaft, and the end of the second rotating shaft partially extends out of the container shell. The end of the second rotating shaft is vertically connected to a driving block, and when the driving head moves the driving block from bottom to top, the second rotating shaft can be driven to rotate downward in the circumferential direction of its axis. A second elastic member is connected between the partition and the inner wall of the container shell, and the second elastic member always has a tendency to restore the partition to a horizontal state.

[0010] The drive box is a hollow container that can accommodate the drive rod to slide therein, and forms a first vertical groove and a second vertical groove for the drive head to slide, and a third vertical groove for the pulling part to slide on the side wall; a first transverse groove and a second transverse groove for the drive head and the pulling part to rotate are respectively formed between the top wall and the side wall, and between the bottom surface and the side wall.

[0011] In order to solve the problem of disinfecting the inside of the storage box without relying on electric energy, the extrusion device includes a peripheral wall embedded in the inside of the disinfectant spraying chamber, an extrusion plate sliding in the peripheral wall, and a spring whose one end contacts the inner surface of the top of the disinfectant spraying chamber and the other end contacts the extrusion plate. The extrusion plate and the peripheral wall can keep the disinfectant spraying chamber relatively airtight.

[0012] Preferably, the driving rod can push the extrusion plate to slide into the inside of the disinfectant spraying chamber to change the volume inside the disinfectant spraying chamber; the disinfectant spraying chamber has a one-way valve, which can prevent the gas in the disinfectant spraying chamber from diffusing outward and replenish air into the disinfectant spraying chamber when the air pressure in the disinfectant spraying chamber is lower than the external air pressure.

[0013] In order to solve the problem that the container of medical waste automatically remains in a sealed state when it is taken out, a movable collection container is also included, and an insertion port for inserting the collection container is opened corresponding to the lower containing chamber, and a second baffle that can open or close the insertion port is hinged on the periphery of the insertion port.

[0014] Furthermore, the collection container has a top cover and a box body, the top cover and the box body are hinged by a third rotating shaft, and a third elastic member is provided between the top cover and the box body, so that the top cover has a tendency to open; the movable end of the top cover of the collection container has a lock buckle, and the lock buckle has deformation ability. When the top cover falls, the lock buckle can buckle the top cover into a lock groove on the inner surface of the box body, and when the lock buckle is deformed, it can be separated from the lock groove to make the top cover flip over and leave the box body; a through hole is provided in the lock groove that passes through the box body, and an unlocking rod is provided inside the container shell, which can pass through the through hole to push the lock buckle open, so that the top cover of the collection container flips over and leaves the box body.

[0015] Compared with the prior art, the advantages of the present invention are: through the cooperation of the driving mechanism arranged on the side of the storage box and the first baffle, the partition, and the disinfectant spraying chamber, when processing and storing medical waste, the three actions of throwing the waste, the waste falling into the collection container, and the disinfection spraying can be completed by the user only needing to pull the driving mechanism once, thereby avoiding the harmful gas in the collection container from diffusing to the outside as much as possible, and the box can be disinfected without relying on electric energy; in addition, the collection container can be automatically opened after being placed in the storage box, and can be sealed by itself when taken out, thereby avoiding the medical waste from falling out and preventing the gas in the collection container from leaking as much as possible.

[0037] The present invention is further described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 19 Shown is the best embodiment of the present invention. The medical waste storage box includes a storage box container shell 12 which is surrounded by a top wall 121 and a first side wall 122, a second side wall 123, a third side wall 124, and a fourth side wall 125 in sequence. The container shell 12 is divided from top to bottom into an upper accommodating chamber 1 and a lower accommodating chamber 2 with relatively independent spaces by a flippable partition 21. A feed port 131 for throwing waste is provided on the first side wall 122 of the container shell 12 corresponding to the upper accommodating chamber 1; the container shell 12 has a disinfectant spraying chamber 3 above the upper accommodating chamber 1, and the disinfectant spraying chamber 3 is connected to the upper accommodating chamber 1 through a plurality of spray channels 31 that can guide disinfectant. Each spray channel 31 is provided with at least one opening for the disinfectant to pass through and spray into the upper accommodating chamber 1, and has deformation ability, keeps a closed state when the pressure at both ends is roughly the same, and opens when the pressure at one end changes significantly, so that the disinfectant can pass through and be sprayed into the upper accommodating chamber 1.

[0040] The interior of the storage box is divided into an upper storage chamber 1 and a lower storage chamber 2 by a partition 21. The partition 21 is connected to the inner side of the first side wall 122 of the storage box through a second rotating shaft 211. A second elastic member 213, such as a spring or a deformable rubber strip, is provided between the partition 21 and the first side wall, so that the partition 21 always has a tendency to return to a horizontal state. Therefore, when the user puts waste into the storage box from the input port 131, the waste is first placed on the partition 21. In order to allow the waste to fall from the upper storage chamber 1 into the lower storage chamber 2, one end of the second rotating shaft 211 near the fourth side wall 125 extends out of the fourth side wall 125, and a long strip driving block 212 is vertically connected to the end facing away from the partition 21. When the driving block 212 is subjected to a thrust and can rotate downward in the circumferential direction of the axis, it can turn over with the partition 21, and at this time, the waste can fall into the lower storage chamber 2. The contact surface of the disinfectant spraying chamber 3 of the present embodiment does not completely overlap with that of the upper accommodating chamber 1, and has a beyond surface 35, on which a squeezing device 32 is provided, which is composed of a peripheral wall 321 vertically embedded in the inside of the disinfectant spraying chamber 3, a squeezing plate 322 sliding in the peripheral wall 321, and a spring 323 whose one end contacts the inner surface of the top of the disinfectant spraying chamber 3 and the other end contacts the squeezing plate 322, the squeezing plate 322 being square and having the same cross-sectional shape as the peripheral wall 321, so that the squeezing device 32 extends into the disinfectant spraying chamber 3 and can also keep the disinfectant spraying chamber 3 relatively airtight. At the same time, the top wall of the disinfectant spraying chamber 3 has a one-way valve 33, which can prevent the gas in the disinfectant spraying chamber 3 from spreading outwards, and when the air pressure in the disinfectant spraying chamber 3 is less than the external air pressure, the disinfectant spraying chamber 3 is replenished with air. Therefore, when the extrusion plate 322 is pushed to move toward the top wall of the disinfectant spray chamber 3, the volume inside the disinfectant spray chamber 3 can be changed, and the pressure of the spray channel 31 toward one end of the disinfectant spray chamber 3 can be increased, so that the opening of the spray channel 31 is opened to squeeze, spray or spray the disinfectant from the spray channel 31 into the upper containing chamber 1.

[0041] In order to isolate the air inside and outside the storage box as much as possible, a first baffle 11 is provided on the input port 131, and is hinged to the upper edge of the input port 131 through a first rotating shaft 111. Due to the influence of gravity, the first baffle 11 always keeps the input port 131 closed. In order to prevent the user from touching the first baffle 11 with one hand when placing waste, the following arrangement is made: one end of the first rotating shaft 111 close to the fourth side wall 125 extends out of the fourth side wall 125, and a transmission mechanism 5 is connected to the end, which can drive the first rotating shaft 111 to rotate circumferentially along the axis, so that the first baffle 11 turns inward or outward.

[0042] Specifically, the transmission mechanism 5 is composed of a first gear 51 , a second gear 52 meshing with the first gear 51 , and a rack, ie, a transmission bar 53 meshing with the second gear 52 . The first gear 51 is connected to the end of the first rotating shaft 111, and the second gear 52 is rotatably connected to the fourth side wall 125. The transmission bar 53 is embedded in a fourth slide groove 532 opened on the fourth side wall 125 perpendicular to the horizontal plane and can slide in the fourth slide groove 532. The side facing away from the fourth side wall 125 is connected to a transmission foot 531 arranged at the lower end of the transmission bar 53. The transmission foot 531 is basically "L"-shaped, including a first foot 531a perpendicular to the fourth side wall 125 and a second foot 531b parallel to the fourth side wall 125. When the second foot 531b of the transmission foot 531 is pushed, the transmission bar 53 slides downward in the fourth slide groove 532, and the second gear 52 converts the linear kinetic energy of the transmission bar 53 into circumferential kinetic energy and transmits it to the first gear 51. The first gear 51 drives the first rotating shaft 111 to flip the first baffle 11.

[0043] In order to allow the user to complete the three steps of waste delivery, dropping into the lower accommodation chamber 13, and disinfection by pulling the driving rod 41 only once, the storage box in this embodiment has a driving mechanism 4, which is connected to the outside of the fourth side wall 125 of the storage box and is located downstream of the squeezing device 32. Specifically, the driving mechanism 4 is composed of a driving rod 41, a first elastic member 42 connected to one end of the driving rod 41, and a driving box 43 for accommodating the driving rod 41 and the first elastic member 42. The driving rod 41 is composed of a rod body 411, a driving head 412, and a pulling portion 413. The driving head 412 and the pulling portion 413 are located at the same horizontal position at the lower part of the driving rod 41, wherein the driving head 412 faces the transmission foot 531, and the pulling portion 413 is away from the transmission foot 531. The first elastic member 42 can be a spring or a rubber strip or other elastic material. The fixed end of the first elastic member 42 is connected to the end of the rod body 411 facing away from the disinfectant spray chamber 3, that is, the lower end, and the free end of the first elastic member 42 supports the bottom of the driving box 43; the rod body 411 can slide downward in a straight line inside the driving box 43 and be pushed upward by the first elastic member 42, and has a tendency to always return to the direction of the disinfectant spray chamber 3 and squeeze the extrusion device 32; the pulling portion 413 allows the user to hold and operate the rod body 411 to slide.

[0044] The drive box 43 includes a box top 431, a first column 433, a second column 434, a third column 435 and a box bottom 432 which are arranged on the four sides of the drive box 43 in sequence, and the fourth column corresponding to the four sides of the drive box 43 is missing to form a third vertical groove 4363. The first column 433, the second column 434 and the fourth side wall 125 are suspended and connected, wherein the second column 434 is connected to the fourth side wall 125 through an L-shaped connecting arm 60, wherein the L-shaped connecting arm includes a first connecting arm 601 which is directly connected to the fourth side wall 125 and perpendicular to the fourth side wall 125 and a second connecting arm 602 which is connected to the first connecting arm 601 and parallel to the fourth side wall 125. The box top 431 and the second column 434 and the third column 435 are not connected to form a first transverse groove 4371; the box bottom 432 and the second column 434 are not connected to form a second transverse groove 4372. Therefore, after the driving rod 41 reaches the position of the second transverse groove 4372, the driving head 412 of the driving rod 41 can be turned in the second transverse groove 4372 to be parallel to the first connecting arm 601, or after the driving rod 41 reaches the position of the first transverse groove 4371, the driving head 412 of the driving rod 41 can be turned in the first transverse groove 4371 to be parallel to the second connecting arm 602, wherein the first vertical groove 4361, the second column 434 and the third column 436 are formed between the first column 433 and the second column 434. 5, a second vertical groove 4362 is formed between the driving rod 41, and when the driving rod 41 reaches the position of the first transverse groove 4371, it slides along the second vertical groove 4362, and the driving rod 41 turns in the second transverse groove 4372 and then slides along the first vertical groove 4361, the second transverse groove second transverse groove first vertical groove second vertical groove first vertical groove second vertical groove first vertical groove second vertical groove the second foot portion 531b of the transmission foot 531 is embedded in the second vertical groove 4362 and can slide therein; the pulling portion 413 slides in the third vertical groove 4363. It should be noted that the drive box 43 can be a rectangular parallelepiped, a cylindrical shape, or any other shape, and the corresponding first, second, third, and fourth columns do not have to be located at the four sides of the rectangular parallelepiped. As long as the drive box is a hollow container that can accommodate the drive rod 41 to slide and rotate therein, it can be considered a homogeneous implementation method. In addition, in order to enable the pulling portion 413 to automatically return to the initial position when the drive rod 41 pushes the extrusion plate 322, a gradually upward convex curved track 4311 can be provided in the top wall 431, and a curved groove 4111 can be correspondingly provided at the upper end of the rod body 411 of the drive rod 41, so that when the pulling portion 413 and the drive head 412 are punching upward, the convex curved track 4311 guides the groove 4111 of the rod body 411, so that the drive head 412 automatically deflects in one direction in the first transverse groove 4371 to return to the initial position.

[0045] The specific operation method is:

[0046] The driving head 412 and the pulling part 413 of the driving rod 41 are firstly in the first transverse groove 4371, and toward the second vertical groove 4362. The user holds the pulling part 413 with one hand and pulls the driving rod 41 to slide downward in the second vertical groove 4362. At this time, the first elastic member 42 stores energy and the transmission foot 531 is pushed downward by the driving head 412, driving the transmission bar 53 to move downward, and sequentially transmits the energy to the second gear 52, the first gear 51, and the first rotating shaft 111, so that the first baffle 11 is flipped open, and then the user uses the other hand to put the waste into the upper containing chamber 1, and the waste is placed on the partition 21. When the driving head 412 and the pulling part 413 of the driving rod 41 reach the second transverse groove 4362, the user holds the pulling part 413 and rotates the driving head 412 to the direction of the first vertical groove 4361. At this time, the first baffle 11 is closed. Then the user releases the pulling part 413, and the driving rod 41 is pushed upward by the energy-storing first elastic member 42. The driving head 412 first hits the driving block 212, causing the driving block 212 to drive the second rotating shaft 211 to rotate clockwise, driving the partition 21 to flip downward, so that the waste falls into the lower accommodating chamber 2. Due to the large initial kinetic energy, the waste is easier to fall. The driving head 412 continues to move upward, and after leaving the driving block 212, since the second elastic member 213 has a tendency to push the partition 21 to restore to a horizontal position, the driving block 212 and the partition 21 are both restored to their initial positions. At this time, the rod body 411 continues to move, and its upper end hits the squeezing plate 322 above, so that it moves toward the internal direction of the disinfectant spraying chamber 3 so that the disinfectant spraying chamber 3 sprays disinfectant toward the upper accommodating chamber 1. When the driving rod 41 leaves the squeezing plate 322 for the next time, the squeezing plate 322 returns to the initial position under the push of the spring 323. At this time, the one-way valve 33 replenishes air into the disinfectant spraying chamber 3 so that the air pressure in the disinfectant spraying chamber 3 and the upper accommodating chamber 1 is consistent, waiting for the next spraying action. In order to facilitate the removal of medical waste, a movable and removable collection container 6 is also provided in the lower accommodating chamber 2, and a handle 67 is provided on the side wall of the collection container 6 to facilitate the user to push and pull. An insertion port 141 with the same height as the collection container is opened at the lower part of the second side wall 123 and at the position of the lower accommodating chamber 2, and a second baffle 23 that can be opened inward is hinged on its upper edge, and the collection container 6 can lift the second baffle 23 to enter the lower accommodating chamber 2.

[0047] In order to automatically keep the collection container 6 in a sealed state when it is taken out, the collection container 6 has a top cover 61 and a box body 62, which are hinged by a third rotating shaft 611, and a third elastic member 63 is provided between the top cover 61 and the box body 62, so that the top cover 61 has a tendency to remain open. The movable end of the top cover 61 has a lock 64, which has the ability to deform. When the top cover 61 falls, the lock 64 can lock the top cover 61 in a lock groove 65 on the inner surface of the box body 62; when the lock 64 is deformed, it can be separated from the lock groove 65 to make the top cover 61 flip out of the box body 62; a through hole 66 that passes through the box body is opened in the lock groove 65, and the third side wall 124 has a protruding unlocking rod 22 at a position facing the through hole 66 in the lower accommodation chamber 2, which can pass through the through hole 66 to push the lock 64 open, so that the top cover 61 of the collection container 6 flips out of the box body 62.

[0048] The specific operation method is: the user inserts the collection container 6 into the lower accommodation chamber 2 through the insertion port 141, and the second baffle 23 opens inward. When the unlocking rod 22 passes through the through hole 66 to open the lock buckle 64, the top cover 61 flips open, so that the second baffle 23 continues to flip upward to an angle perpendicular to the horizontal plane, and waste can be put into the collection container. When the collection container needs to be taken out, the user pulls the handle 67 to pull out the collection container 6. At this time, since the height of the insertion port 141 is the same as that of the collection container 6, the top cover 61 gradually falls under the limiting action of the upper edge of the insertion port 141, and finally reaches the closed position. At this time, the lock buckle 64 is buckled into the lock groove 65 to close the collection container 6.

[0049] Example 2

[0050] like Fig. 20 and 21 A waste storage box shown is another embodiment of the present invention. The difference from embodiment 1 is that the disinfectant spraying chamber 3 is connected to the side of the third side wall 124 of the storage box, and an inlet 131 is provided on the top wall 12, the baffle 11 is connected to the side of the inlet 131 toward the disinfectant spraying chamber 3 through the first rotating shaft 111, and a fourth elastic member 112 is connected inside the baffle 11 and the top wall 12 so that the baffle 11 keeps the trend of closing the inlet 131. The driving mechanism 4 is placed horizontally, and the movement direction of its driving rod 41 is horizontal.

[0051] The specific operation method is roughly the same as that of Example 1, with the main difference being that waste is put into the box from the input port 131 on the top wall of the storage box, and the pulling and releasing directions of the driving mechanism 4 are changed to horizontal to correspond to different operating habits; it should be noted that the pulling portion 413 of the driving mechanism can be controlled not only by hand but also by foot pedal, and the control method can be flexibly changed by simply changing the size of the box.
