The invention aims to provide a self-sealing type chemotherapy article garbage storage device, which solves the problem that chemotherapy wastes stored in the garbage storage device are easy to damage human health when the chemotherapy wastes are stored in the garbage storage device in the prior art.

The scheme is basically as follows: a self-sealing type chemotherapy article garbage storage device comprises a barrel body with an opening at the upper end, wherein a barrel cover capable of covering the upper end of the barrel body is rotatably connected to the upper end of the barrel body, a driving mechanism for driving the barrel cover to rotate is arranged on the barrel body, a sealing plate is movably connected in the barrel body, the sealing plate can divide an inner cavity of the barrel body into a temporary storage cavity and a storage cavity, and the temporary storage cavity is positioned above the storage cavity; a linkage mechanism is arranged between the driving mechanism and the sealing plate, and when the driving mechanism drives the barrel cover to be opened, the linkage mechanism drives the sealing plate to separate the temporary storage cavity from the storage cavity under the action of the driving mechanism; when the driving mechanism drives the barrel cover to cover the barrel body, the linkage mechanism drives the sealing plate to move under the action of the driving mechanism, so that the temporary storage cavity is communicated with the storage cavity.

The principle of the invention is as follows: the driving mechanism is used for driving the barrel cover to rotate, so that the barrel cover is opened, then the chemotherapy waste can be put into the barrel body, and meanwhile, the driving mechanism can drive the barrel cover to seal the opening at the upper end of the barrel body, so that the interior of the barrel body is isolated from the outside, and the harm of the air of the chemotherapy waste barrel cover to a human body is avoided; when the driving mechanism drives the barrel cover to be opened, the driving mechanism drives the linkage mechanism to drive the sealing plate to move, so that the temporary storage cavity and the storage cavity are isolated by the sealing plate, the storage cavity for storing the chemotherapy wastes is isolated from the outside by the sealing plate, the harm to a human body caused by the chemotherapy wastes which are placed in the storage cavity is avoided, and meanwhile, the chemotherapy wastes which are subsequently put are placed on the sealing plate; then, the driving mechanism is used for driving the barrel cover to cover the barrel body, the barrel cover seals the barrel body, meanwhile, the driving mechanism drives the linkage mechanism, the linkage mechanism drives the sealing plate to move, the temporary storage cavity is communicated with the storage cavity, and chemotherapy wastes newly input on the sealing plate fall into the storage cavity.

Has the advantages that:

1. can effectively reduce the harm of chemotherapy waste to human body: compare and utilize the diaphragm to keep apart the space and the external world of placing the chemotherapy discarded object among the prior art, when the people put into the disposal bag in to the disposal bag, the air that is full of the chemotherapy medicine in the disposal bag can directly contact with the human body and make the human body receive harm. In this application, set up the storage chamber of the interior chamber of keeping in of separating into upper portion and lower part of closing plate in with the staving, when throwing in the chemotherapy discarded object to the storage chamber, at first throw in the chemotherapy discarded object on the closing plate, the chemotherapy discarded object that the closing plate will store the intracavity and has deposited this moment is kept apart, avoid it to cause harm to the human body, and when the bung lid closed on the staving, the chemotherapy discarded object on the closing plate can fall into the storage intracavity automatically, thereby make the human body receive the harm of chemotherapy discarded object and reduce when throwing in the chemotherapy discarded object to the storage chamber.

2. Can prevent the chemotherapy waste from causing harm to human body: compared with the prior art in which the chemotherapy waste needs to be pushed into the channel of the diaphragm manually, the chemotherapy waste stored in the garbage bag can easily stab the hands of a human body, and the chemotherapy drug remained on the chemotherapy waste can cause secondary damage to the human body, so that the human body is injured by the chemotherapy waste. In this application, put in the chemotherapy discarded object, directly place the chemotherapy discarded object on the closing plate, when the bung lid was fashionable, the chemotherapy discarded object on the closing plate automatically fell into the storage intracavity and is saved, avoids human hand to be stabbed by the chemotherapy discarded object that has deposited in the storage intracavity, and is safer.

3. Simple structure, easily operation: in this application, when utilizing actuating mechanism to promote the bung to open and close with the lid, actuating mechanism automatic drive link gear acts on the closing plate for when manual to putting into the chemotherapy discarded object in the bucket, the closing plate will keep in the chamber and store the chamber and keep apart, avoid storing intracavity chemotherapy discarded object and cause harm to the human body, and when the bung lid, the chemotherapy discarded object on the closing plate can fall into automatically and store the intracavity, this garbage storage device simple structure, easily operation.

Further, actuating mechanism includes the footboard, draws piece and first elasticity to reset, and footboard sliding connection is on the staving, and the one end fixed connection of drawing the piece is on the footboard, other end fixed connection is on the bung, and first elasticity resets and fixes a connection between staving and footboard.

When the barrel cover needs to be opened, only the foot of a human body steps on the pedal, so that the pedal pulls the first traction piece to move, the first traction piece pulls the barrel cover to rotate, the opening at the upper end of the barrel body is opened, and meanwhile, the first elastic resetting piece is elastically deformed to store force; when the acting force of the foot on the pedal disappears, the pedal resets under the restoring force action of the first elastic resetting piece, so that the barrel cover is automatically covered, the structure is simple, and the barrel cover can be conveniently and quickly opened and covered.

Furthermore, the linkage mechanism comprises a second traction piece and a second elastic reset piece, one end of the second traction piece is fixedly connected to the pedal, and the other end of the second traction piece is fixedly connected to the sealing plate; the second elastic reset piece is fixedly connected between the barrel body and the sealing plate.

When the foot pedal is used for enabling the pedal to slide, the pedal synchronously drives the second traction piece to move, and the second traction piece drives the sealing plate to move when moving, so that the sealing plate moves along the inner wall of the barrel body, and the effect that the temporary storage cavity and the storage cavity are separated and communicated when the barrel cover is opened and closed by the driving mechanism is realized; the second elasticity resets between staving and closing plate fixed connection, and when the bung lid was closed, the second elasticity resets and drives the closing plate and reset to the chamber of keeping in and the storage chamber intercommunication make, the chemotherapy discarded object on the closing plate falls to the storage intracavity automatically.

Further, the closing plate rotates to be connected in the staving inner wall, and when second elasticity reset piece was in natural state, the closing plate was in the tilt state and the free end of closing plate was the low end, fixedly connected with locating part on the staving inner wall.

The closing plate rotates to be connected on the inner wall of staving, when the bung lid closes on the staving, the second elasticity resets and is in natural state, closing plate slope this moment sets up and its free end is located the low side, make the chemotherapy discarded object on the closing plate can fall into the storage chamber along the closing plate of slope, because the closing plate slope has direction cushioning effect to the chemotherapy discarded object when setting up, and when the chemotherapy discarded object falls into the storage chamber by the closing plate low side, the difference in height that drops reduces in the vertical direction, thereby make the chemotherapy discarded object receive the impact force when falling in the storage chamber and reduce, avoid the medicine ampoule breakage in the chemotherapy discarded object, thereby avoid remaining chemotherapy medicine in the medicine ampoule to overflow in a large number.

Further, fixedly connected with guide on the staving inner wall, closing plate sliding connection is on the guide.

Fixed connection guide on the staving inner wall, when the bung lid closes on the staving, there is the clearance between closing plate and the staving inner wall, make the intracavity chemotherapy discarded object of keeping in can fall into the storage intracavity, and when the bung was opened, the closing plate moved to the inner wall laminating with the staving under second elasticity piece and the second traction piece combined action, thereby utilize the closing plate to keep in the chamber and keep apart with the storage chamber, avoid storing intracavity chemotherapy discarded object and causing harm to the human body, compare in the closing plate rotation connection on the inner wall of staving, in this application scheme, the closing plate is sliding connection on the guide, it is littleer to make the closing plate occupy the staving inner space during the motion, thereby make the staving have bigger storage space.

Further, a piston cavity is arranged at the bottom of the barrel body, a piston plate is connected in the piston cavity in a sliding mode, and the piston plate is fixedly connected with the pedal; the piston cavity is provided with an air inlet hole and an air outlet hole, an air inlet pipe is connected between the air inlet hole and the temporary storage cavity, and a filter is arranged at the air outlet hole.

Because the bung lid closes when on the staving, the chamber of keeping in is in the connected state with storing the chamber for keep in the chamber all be full of by the gas that contains the chemotherapy medicine of storing intracavity chemotherapy discarded object release with storing the intracavity, although the closing plate can be temporarily keep in the chamber and keep apart when opening the bung, but keep in the intracavity still can contain the gas of taking the chemotherapy medicine, still have a small amount of chemotherapy medicine to diffuse in the air and harm health after opening the bung. In the scheme, when the foot of a human body steps on the pedal, the pedal drives the piston plate in the piston cavity to slide, so that the piston cavity sucks air from the air inlet hole, the air inlet hole sucks air from the temporary storage cavity through the air inlet pipe, and the gas diffused from the temporary storage cavity to the outside when the barrel cover is opened is reduced, so that the harm of a small amount of chemotherapeutic drugs in the temporary storage cavity to the human body is reduced, and the harm to the human body is smaller; when the pedal resets, the air in the piston cavity is exhausted through the exhaust hole, the filter filters the air, and chemotherapy drugs contained in the air in the piston cavity are prevented from being directly exhausted to the outside through the exhaust hole.

Further, the first traction piece comprises a traction rod and a first traction rope fixedly connected to the traction rod, the first traction rope is fixedly connected with the pedal, and the traction rod is fixedly connected with the barrel cover; the second traction member includes a second elastic traction cord, the first traction cord being in a relaxed state and the second elastic traction cord being in a stretched state when the first elastic member is in a natural state.

When the bung was opened, if bung and closing plate took place the motion simultaneously, not only can inhale the outside air when the intracavity gas was kept in piston chamber absorption this moment, still can the suction store intracavity portion have the gas of chemotherapy medicine simultaneously to make the reduction amount of keeping in intracavity chemotherapy medicine less, the effect that the intracavity chemotherapy medicine was kept in piston chamber absorption is not particularly obvious. In the scheme, the first traction piece comprises a traction rod and a first traction rope, the second traction piece comprises a second elastic traction rope, when the first elastic reset piece is in a natural state, the first traction rope is in a loose state, the second elastic traction rope is in a stretching state, the pedal is treaded to enable the second elastic traction rope to be pulled firstly, thereby the sealing plate isolates the temporary storage cavity from the storage cavity, the second elastic traction rope generates elastic deformation along with the continuous treading of the pedal, the sealing plate continuously isolates the temporary storage cavity from the storage cavity, the pedal can pull the barrel cover to open through the first traction rope and the traction rod, so that when the barrel cover is opened and the air inlet pipe exhausts the temporary storage cavity, the temporary storage cavity can only suck air from the outside to the temporary storage cavity, thereby avoiding the outward diffusion of the gas containing the chemotherapy drugs in the temporary storage cavity, and ensuring that the human body has less harm to the chemotherapy wastes.

Furthermore, an air supplement hole communicated with the temporary storage cavity is formed in the inner wall of the barrel body, and a one-way valve only allowing gas outside the barrel body to enter the temporary storage cavity is arranged on the air supplement hole.

When the footboard was stepped on and made the closing plate rotate and the bung not open, because the intake pipe constantly will keep in the intracavity air suction to the piston chamber for keep in the chamber and form the negative pressure, and keep in the chamber and store the chamber after keeping in the closing plate and keep apart, if the chamber of keeping in is negative pressure state, causes the bung can't be opened easily. In this scheme, more preferably, set up the tonifying qi hole of keeping in the chamber intercommunication on the staving lateral wall, when the bung lid closes and keeps in intracavity gas by suction piston chamber, can be followed external suction air by the tonifying qi hole after the chamber of keeping in forms the negative pressure for keep in intracavity atmospheric pressure and external atmospheric pressure difference are little, make things convenient for the bung to open smoothly, easily.
