[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1, as Figure 1 As shown, a disposable syringe destruction device includes a destruction chamber 1, a separation chamber 6 is fixedly connected to the upper end of the destruction chamber 1, a control cabinet 5 is fixedly installed at the front end of the destruction chamber 1, a destruction screening structure 2 is arranged in the inner cavity of the destruction chamber 1, a needle separation structure 3 connected to the inner cavity of the destruction chamber 1 is arranged in the inner cavity of the separation chamber 6, and a feeding auxiliary component 4 is arranged together at the right end of the separation chamber 6 and the right end of the destruction chamber 1.

[0036] It should be noted that the control cabinet 5 is a conventional control device, which is mainly used to control the start and stop of the motor. The device has been widely used in the prior art and is a mature prior art. Its internal structure, operating principle, wiring and control method will not be described in detail.

[0037] Further, in order to assist the medical staff to press the syringe into the needle separation structure 3, refer to Figure 2The feeding auxiliary component 4 includes an anti-lost rope 41 fixedly connected to the separation chamber 6, and the end of the anti-lost rope 41 away from the separation chamber 6 is fixedly connected to an anti-slip handle 42, and the end of the anti-slip handle 42 away from the anti-lost rope 41 is fixedly connected to a compression block 43 that is adapted to the shape of the syringe silo 31, and the right end of the destruction chamber 1 is symmetrically fixedly connected to a J-shaped plate 44 that is buckled with the compression block 43 corresponding to the position of the anti-lost rope 41.

[0038] The medical staff can hold the non-slip handle 42 and press the syringe into the needle separation structure 3 through the pressing block 43. When the syringe is stuck in the needle separation structure 3, the pressing block 43 can push the syringe to move into the destruction screening structure 2, and the syringe is stored in the destruction screening structure 2 after being crushed and classified. The J-shaped plate 44 can clamp the pressing block 43 on the right side of the destruction chamber 1, and cooperate with the anti-lost rope 41 to prevent it from being lost when not in use.

[0039] During the operation of this embodiment, the syringe and the needle are separated by the action of the needle separation structure 3, and there is no need for medical staff to perform manual separation, thereby reducing the contact between medical staff and the needle and reducing unnecessary occupational exposure. The separated syringe and needle are sent to the destruction screening structure 2 for crushing and destruction respectively through the cooperation of the feeding auxiliary component 4 and the needle separation structure 3, and the metal debris after the needle is crushed is separated from the plastic particles, thereby avoiding the metal debris from causing harm to the processing personnel during the subsequent plastic particle processing, thereby further improving safety.

[0040] Embodiment 2: Based on embodiment 1, this embodiment utilizes the syringe bin 31 and the needle bin 32 opened at the upper end of the separation chamber 6 to facilitate medical staff to put in the syringe, and limits the piston handle through the syringe limiting assembly 35. The separation guide plate 34 installed between the needle bin 32 and the syringe bin 31 and the connecting groove 341 opened on its surface can separate the needle when the pressure block 43 presses the syringe downward, and then the crushing feeding assembly 36 is used to transport the syringe downward so that it can be crushed by the destruction screening structure 2, without the need for medical staff to manually split it, thereby reducing the risk of occupational exposure.

[0041] Because the needle is inserted tightly, it is usually pulled out manually by medical staff. Although this operation method is simple, some liquid medicine will remain in the needle. During the removal process, occupational exposure will inevitably occur. Whether it is liquid medicine splashing into the mouth, nose and eyes of medical staff, or scratches by needles or fragments, it will cause infection to medical staff and affect their health.

[0042] Specifically, in order to separate the syringe and the needle, medical staff do not need to manually separate them, reduce the contact between medical staff and the needle, and reduce unnecessary occupational exposure, refer to Figure 3The needle separation structure 3 includes a syringe bin 31 opened at the front upper end of the separation chamber 6 and a needle bin 32 opened at the rear upper end of the separation chamber 6, a syringe limiting assembly 35 is symmetrically arranged at the front inner surface of the syringe bin 31, a crushing feeding assembly 36 is symmetrically arranged at the lower inner surface of the syringe bin 31, and a splash-proof assembly 33 is symmetrically arranged at the upper inner surface of the needle bin 32, and a separation guide plate 34 is fixedly connected to the junction of the needle bin 32 and the syringe bin 31, and the separation guide plate 34 is vertically Z-shaped and a connecting groove 341 connected to the rear end is opened at its front end.

[0043] The syringe bin 31 is used to accommodate the barrel of the syringe, and the syringe limiting assembly 35 arranged inside it is used to limit the syringe at the piston handle. The separation guide plate 34 is a vertically installed Z-shaped plate, and the connection between the two vertical parts is an arc track. The width of the connecting groove 341 is larger than the liquid outlet pipe at the front of the syringe, but smaller than the base of the needle.

[0044] like Figure 3 As shown, when the syringe is placed in the syringe bin 31 and the needle bin 32, the needle part will enter the needle bin 32 through the splash-proof assembly 33, and the syringe part will be in the syringe bin 31. Therefore, when passing through the arc portion of the separation guide plate 34, the needle is separated from the syringe and falls downward into the destruction screening structure 2. The syringe will also fall downward in the syringe bin 31 until it passes over the syringe limit assembly 35 and enters the range of the crushing feed assembly 36, and enters the destruction screening structure 2 under the action of the crushing feed assembly 36.

[0045] Further, in order to prevent the separated needle from being ejected from the upper side of the needle bin 32 under the action of the separation guide plate 34 and reduce safety hazards, refer to Figure 4 and Figure 5 The splash-proof assembly 33 includes a central shaft 334 rotatably connected to the rear side wall of the inner surface of the needle bin 32 and the rear end of the separation guide plate 34. The outer surface of the central shaft 334 is fixedly connected to a clockwork spring 333 fixedly connected to the inner surface of the needle bin 32. The outer surface of the central shaft 334 is fixedly connected to a flap 331. The lower part of the flap 331 away from the center of the needle bin 32 is provided with an arc surface 332. The syringe bin 31 and the needle bin 32 are both connected to the inner cavity of the destruction chamber 1.

[0046] Under the action of the curved surface 332, the flap 331 can only flip downward in one direction in a horizontal state. When the needle is pressed downward, the flap 331 drives the central axis 334 to rotate. At this time, the clockwork spring 333 is forced to accumulate elastic potential energy. When the needle passes over, the central axis 334 will drive the flap 331 to reset upward under the action of the clockwork spring 333 until the flap 331 returns to the horizontal position. When the needle in the needle bin 32 is separated from the syringe under the action of the separation guide plate 34 and the connecting groove 341, it may run around, resulting in an upward collapse. At this time, the flap 331 can prevent the needle from flying out of the needle bin 32, thereby improving safety.

[0047] Further, in order to limit the position of the syringe piston handle, the auxiliary separation guide plate 34 is used to separate the needle. Figure 6 The syringe limiting assembly 35 includes a piston handle limiting groove 353 opened on the inner wall of the syringe bin 31 away from the center of the syringe bin 31, and the rear part of the inner surface of the piston handle limiting groove 353 is slidably connected with an arc plate 351 through the opened limiting groove, and a plurality of compression springs 352 are linearly distributed and fixedly connected to the rear end of the arc plate 351. The front side of the arc plate 351 is tightly attached to the front part of the inner surface of the piston handle limiting groove 353 in the initial state.

[0048] On the front side of the syringe is the piston handle, that is, the part that the index finger and middle finger hook during the medicine pushing process. After the syringe enters the syringe bin 31, the piston handle will enter the piston handle limiting groove 353 and will contact the arc plate 351, pressing it into the piston handle limiting groove 353. At this time, the compression spring 2 352 is stressed and provides pressure to the piston handle through the arc plate 351, reducing the displacement of the syringe when the needle is pulled by the separation guide plate 34 and is about to separate from the syringe.

[0049] Further, in order to assist the syringe to enter the destruction chamber 1 and be crushed by the destruction screening structure 2, see Figure 7 The crushing feeding assembly 36 includes a mounting groove 367 opened on the inner surface of the syringe silo 31 away from the center of the syringe silo 31, and the inner surface of the mounting groove 367 is symmetrically provided with slide grooves 361, and the inner surface of the mounting groove 367 is slidably connected with a U-shaped bracket 363, and the front and rear ends of the U-shaped bracket 363 are symmetrically fixedly connected with pulleys 362 that are slidably connected to the inner surface of the adjacent slide groove 361, and the inner surface of the U-shaped bracket 363 is fixedly installed with a power shaft 365, and the outer surface of the output side of the power shaft 365 is linearly distributed and fixedly connected with a plurality of friction wheels 364, and one end of the U-shaped bracket 363 away from the friction wheel 364 is linearly distributed and fixedly connected with a plurality of compression springs 366 that are fixedly connected to the inner surface of the mounting groove 367, and the friction wheel 364 is located outside the mounting groove 367 in the initial state.

[0050] After the syringe is separated from the needle, it will move downward over the arc plate 351 and enter the range of the friction wheel 364. The friction wheel 364 will continue to rotate under the action of the slide groove 361, and give the syringe a reaction force under the action of the compression spring three 366, so that the friction wheel 364 contacts the outer surface of the syringe, and drives the syringe to move downward through rotation, pressing it into the destruction screening structure 2.

[0051] Embodiment 3. Based on embodiment 2, this embodiment further drives the crushing wheel 211 to rotate through the driving motor 1 213 to crush the needles and syringes separately, thereby destroying the needles and syringes, and the needle particles are evenly sent to the sorting component 24 or the syringe particles are directly sent to the front waste storage structure 25 through the grid 22, and the metal debris in the needle particles is further separated through the cooperation of the magnetic coating 243 and the magnetic block 244 in the sorting component 24, and is sent to the waste storage structure 25 on the rear side for storage by the action of the scraper 245, so as to realize the classified storage of metal debris and plastic particles.

[0052] Specifically, to achieve the destruction and classification of needles and syringes, refer to Figure 8 , Fig. 9 and Fig.10 The destruction and screening structure 2 includes a crushing component 21 installed on the upper part of the inner cavity of the destruction chamber 1, a grille 22 is fixedly connected to the middle part of the inner cavity of the destruction chamber 1 symmetrically in the front and back, and a separation plate 23 corresponding to the position of the separation guide plate 34 is fixedly connected to the part of the inner cavity of the destruction chamber 1 located between the two grilles 22. A sorting component 24 is arranged at the lower side of the grille 22 at the rear of the lower part of the inner cavity of the destruction chamber 1, and a waste storage structure 25 connected to the left end of the destruction chamber 1 is symmetrically arranged in the lower part of the inner cavity of the destruction chamber 1.

[0053] The crushing component 21 is used to destroy needles and syringes, crush them into fragments, and make them move downward more evenly through the action of the grille 22. The syringes and push rods dropped from the syringe bin 31 will directly enter the front control cabinet 5 through the front grille 22 after being crushed. The needles dropped from the needle bin 32 will first pass through the rear grille 22 and fall on the sorting component 24 after being crushed, and the metal fragments of the needles will be sent to the waste storage structure 25 at the rear after being classified by the sorting component 24. The plastic particles will enter the front waste storage structure 25 through the action of the sorting component 24, thereby realizing the separate storage of metal and plastic particles.

[0054] Further, to achieve the destruction of needles and syringes, see Fig. 9The crushing assembly 21 includes a crushing wheel 211 which is symmetrically connected to the inner surface of the destruction chamber 1 for rotation. A driving motor 213 is fixedly connected to the inner cavity of the destruction chamber 1. A gear set 212 is fixedly connected to the output end of the driving motor 213. The inner surfaces of the two output gears of the gear set 212 which rotate relatively to each other are respectively fixedly connected to the rear ends of the adjacent crushing wheels 211. The middle part of the outer surface of the crushing wheel 211 is rotationally connected to the inner surface of the isolation plate 23.

[0055] The gear set 212 is composed of a plurality of gears meshing with each other, so that the two gears on both sides can drive the crushing wheel 211 to rotate in opposite directions, and the direction of rotation is to rotate toward its staggered position. The driving motor 213 is used to drive the gear set 212 to rotate, thereby driving the crushing wheel 211 to rotate. The crushing wheel 211 is divided into two parts by the isolation plate 23, so as to crush the needle and the syringe separately.

[0056] Further, in order to separate the metal and plastic particles in the needle and avoid the metal debris from causing harm to the processing personnel during the subsequent plastic particle processing, refer to Fig.10 The sorting component 24 includes a conveyor belt 242 installed on the inner surface of the destruction chamber 1 and located at the lower side of the rear grille 22. The front pulley of the conveyor belt 242 is located in front of the isolation plate 23 and its outer surface is covered with a magnetic coating 243. A magnetic block 244 is fixedly connected to the position behind the front pulley of the conveyor belt 242 on the inner surface of the destruction chamber 1. A scraper 245 tightly attached to the lower end of the conveyor belt 242 is fixedly connected to the position below the magnetic block 244 on the inner surface of the destruction chamber 1. A driving motor 241 drivingly connected to the rear pulley of the conveyor belt 242 is fixedly installed at one end of the destruction chamber 1.

[0057] The second driving motor 241 drives the sorting component 24 to operate, thereby transporting the particles containing metal debris transported downward from the upper side forward. When passing through the magnetic coating 243, the metal particles will be adsorbed by the magnetic coating 243 and reach the lower side of the sorting component 24 under the action of the magnetic force. The plastic particles will enter the front waste storage structure 25 under the action of inertia, and the metal particles will be scraped off by the scraper 245 and fall into the rear waste storage structure 25.

[0058] The needle is usually made of stainless steel, which is a ferromagnetic material, so the needle can be adsorbed by a magnet. The magnetic coating 243 and the scraper 245 are both electromagnets. They are magnetic when powered on and can adsorb metal debris produced after the needle is broken. While passing through the scraper 245, the magnetic block 244 weakens the effect of the metal ions on the lower side of the sorting component 24, and the metal ions will fall off the sorting component 24 and fall into the waste storage structure 25 at the rear.

[0059] Further, in order to store the destroyed materials in the waste storage structure 25 and facilitate the medical staff to take them out, refer to Fig.11 The waste storage structure 25 includes a storage box 251 slidably connected to the inner surface of the destruction chamber 1. The storage box 251 corresponds to the position of the adjacent grille 22 in the vertical direction. A snap-fit ​​groove 255 is provided at the lower left end of the storage box 251. A T-shaped groove 253 is provided at the lower side of the left end of the destruction chamber 1. A locking tongue 252 is slidably connected to the inner surface of the T-shaped groove 253. A compression spring 254 is fixedly connected to the lower end of the locking tongue 252. A sliding block 256 slidably connected to the inner surface of the T-shaped groove 253 and the left end of the destruction chamber 1 is fixedly connected to the left end of the T-shaped groove 253.

[0060] Metal particles or plastic particles fall into the storage box 251. When it is almost full, the medical staff can move the sliding block 256 to make it move downward. At this time, the compression spring 254 is compressed by the force to compress the locking tongue 252 and retract it into the T-slot 253 and separate it from the snap-fit ​​groove 255.
