The operation is cumbersome and labor-intensive, and there is a risk of needlestick injury. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0004] An automatic medical waste sorting and processing storage box includes a box body, on which a needle remover and a shearer are mounted. The needle remover includes a mounting base, a movable plate, a fixed plate, a needle removal seat, a connecting base, and a rotating motor. The rotating motor is slidably mounted on the box body, and a needle removal electric actuator is fixedly mounted on the box body to drive the rotating motor to slide. The needle removal seat is connected to the rotating motor through the connecting base, and the rotating motor drives the needle removal seat to rotate.

[0017] Furthermore, the automatic cutting and sorting medical waste storage box also includes a control system. The control system is installed on a control panel. The control system first controls the needle removal motor to drive the movable plate to rotate, clamping and fixing the needle to the fixed plate; then controls the extension of the cutting electric actuator to control the front end of the movable shears to rotate and cooperate with the fixed shears to cut the infusion tube; then controls the retraction of the needle removal electric actuator to move the needle removal seat to the right, pulling the needle out of the infusion bag and placing it above the needle groove; then controls the rotation motor to drive the needle removal seat to rotate, causing the movable plate and fixed plate to rotate and tilt; then controls the needle removal motor to drive the movable plate to rotate and separate from the fixed plate, releasing the clamp on the needle and allowing the needle to fall into the sharps container for collection under gravity; then controls the rotation motor to drive the needle removal seat to rotate, causing the movable plate and fixed plate to return to their original positions; then controls the extension of the needle removal electric actuator to move the needle removal seat to the left and attach it to the holder; finally, controls the retraction of the cutting electric actuator to control the front end of the movable shears to rotate back to its original position.

[0018] Furthermore, the control system includes a fixing module, a cutting module, and a needle removal module;

[0019] The fixing module is used to control the needle-pulling motor to drive the movable plate to rotate and to fit or separate from the fixing plate;

[0020] The shearing module is used to control the extension of the shearing electric actuator to drive the front end of the movable shear plate to rotate closer to the fixed shear plate, or to control the retraction of the shearing electric actuator to drive the front end of the movable shear plate to rotate away from the fixed shear plate.

[0021] The needle removal module is used to control the retraction of the needle removal electric push rod to move the needle removal seat to the right and above the needle groove, or to control the extension of the needle removal electric push rod to move the needle removal seat to the left and stick to the card seat.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This invention features bottle slots, tubing slots, and needle slots on the casing, with slidably detachable bottle collection frames, tubing collection frames, and sharps containers for collecting infusion bottles, tubing, and needles respectively. A needle extractor is positioned above the needle slot, and a shearing device is located to the right of the needle slot. In use, an infusion bag with a needle inserted is placed on a holder, with the needle at the notch. A pressure plate secures the infusion bag to the holder. The infusion tubing connected to the needle is placed in the cutting slot, between the movable and fixed shearing plates of the shearing device. The needle extractor's motor drives the movable plate to rotate, clamping and fixing the needle to the fixed plate. The needle is then sheared... The extension of the electric shearing rod controls the rotation of the front end of the movable shearing plate, which works in conjunction with the fixed shearing plate to cut the infusion tube, separating the infusion tube from the needle. Then, the retraction of the needle-pulling electric rod causes the needle-pulling seat to move to the right, pulling the needle out of the infusion bag and placing it above the needle groove. The rotation of the needle-pulling seat, driven by the rotation motor, causes the movable plate and the fixed plate to rotate and tilt. The needle-pulling motor drives the movable plate to rotate and separate from the fixed plate, releasing the clamp on the needle. The needle then falls into the sharps container for collection under the action of gravity, thus achieving automatic separation and collection of the needle, avoiding hand contact, preventing needle pricks, and reducing workload through automation.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] In the daily medical waste disposal of medical institutions, such as after a routine infusion, the infusion bag and infusion set are collected together in the disposal room. The needle on the infusion set is inserted into the infusion outlet of the infusion bag. The nurse needs to use scissors to cut off the non-sharp part and throw it into the yellow garbage bag, then remove the needle and throw it into the sharps box 6 to collect the infusion bag. The operation is cumbersome and labor-intensive, and there is a risk of needle stick injury.

[0036] In this embodiment, to solve the above problems, the first consideration is to combine the three containers for collecting the infusion bag, infusion tubing, and needle into a large container for easy storage. Secondly, to avoid hand injuries during needle removal, it is necessary to minimize hand contact with the needle; therefore, the infusion bag is fixed in place, and the needle is held in place by a clamping structure for easy removal. Finally, to separate the needle from the infusion tubing, an automatic tubing-cutting mechanism is also needed. The specific design is as follows:

[0037] Please see Figure 1-8 An automatic cutting and sorting medical waste storage box includes a box body 1. The box body 1 has a bottle slot 11, a tube slot 12, and a needle slot 13. A bottle collection frame 4, a tube collection frame 5, and a sharps box 6 are slidably and detachably arranged in the bottle slot 11, tube slot 12, and needle slot 13, which can collect infusion bottles, infusion tubes, and needles respectively.

[0038] In this embodiment, to cut the infusion tube, a shearer 7 is installed on the housing 1. The shearer 7 includes scissors and a shearing electric actuator 71. The scissors are movably mounted on the housing 1, and the shearing is controlled by the extension and retraction of the shearing electric actuator 71. A cutting groove 14 is opened on the right side of the needle groove 13, and the infusion tube is placed in the cutting groove 14. The scissors of the shearer 7 include a movable shear plate 72, a fixed shear plate 73, and a connecting column. The connecting column is fixedly installed in the housing 1, and the fixed shear plate 73 is fixedly connected to the connecting column. The middle part of the movable shear plate 72 is rotatably sleeved on the connecting column. The fixed shear plate 73 is located at the bottom of the cutting groove 14. A movable groove is opened at the rear end of the movable shear plate 72, and a movable column is fixedly provided at the extended end of the shearing electric actuator 71. The movable column moves along the movable groove, and the extension of the shearing electric actuator 71 controls the front end of the movable shear plate 72 to rotate and reduce the angle between the movable shear plate 72 and the fixed shear plate 73.

[0039] The extension of the shearing electric push rod 71 of the shearer 7 controls the front end of the movable shearing plate 72 to rotate and cooperate with the fixed shearing plate 73 to cut the infusion tube, so that the infusion tube is separated from the needle.

[0040] In this embodiment, a needle puller 9 is provided on the housing 1 to remove the needle from the infusion bag outlet. The needle puller 9 includes a retainer 98, a movable plate 95, a fixed plate 97, a needle puller seat 94, a connecting seat 93, and a rotating motor 92. The rotating motor 92 is slidably mounted on the housing 1, and a needle puller push rod 91 is fixedly mounted on the housing 1 to drive the rotating motor 92 to slide. The needle puller seat 94 is connected to the rotating motor 92 through the connecting seat 93, and the rotating motor 92 drives the needle puller seat 94 to rotate. One end of the fixed plate 97 is fixedly mounted on the needle puller seat 94, and one end of the movable plate 95 is movably connected to the needle puller seat 94. A needle-pulling motor 910 drives a movable plate 95 to rotate and fit against a fixed plate 97. The needle puller 9 is installed above the needle groove 13, the needle-pulling electric push rod 91 is fixedly installed on the upper side of the needle groove 13, and the card holder 98 is fixedly installed on the left side of the needle groove 13. An arc-shaped plate 99 is fixedly installed at one end of the movable plate 95. The arc-shaped plate 99 slides into the needle-pulling seat 94 in an arc shape. The inner side of the arc-shaped plate 99 is provided with a toothed structure. A gear that cooperates with the toothed structure is fixedly installed on the output shaft of the needle-pulling motor 910. By driving the gear to rotate through the needle-pulling motor 910, the arc-shaped sliding of the arc-shaped plate 99 is controlled, thereby adjusting the angle between the movable plate 95 and the fixed plate 97.

[0041] In this embodiment, the card holder 98 includes a fixed seat 981, a pressure plate 982, a movable rod 984, and an anti-rotation plate 985. The fixed seat 981 and the anti-rotation plate 985 are fixedly installed on the housing 1. The fixed seat 981 has a notch on the side near the needle puller 94. A handle 983 is fixedly provided on the pressure plate 982. The movable rod 984 is vertically inserted into the housing 1, that is, the movable rod 984 can rotate around its own axis and slide up and down. The pressure plate 982 is fixedly connected to the movable rod 984. The purpose of this design is that the pressure plate 982 can rotate around the movable rod 984 and can slide down. Press or lift the pressure plate 982; when the pressure plate 982 rotates to be parallel with the fixed seat 981, the anti-rotation plate 985 restricts the pressure plate 982 from continuing to rotate; during use, place the infusion bag on the card holder 98 with the needle at the notch, and place the infusion outlet of the infusion bag on the fixed seat 981. By holding the handle 983, rotate the pressure plate 982 to be parallel with the fixed seat 981, that is, the pressure plate 982 is above the infusion outlet of the infusion bag. Pressing down the pressure plate 982 will fix the infusion outlet of the infusion bag on the fixed seat 981; after cutting and removing the needle, lift the pressure plate 982 to rotate it to be offset from the fixed seat 981, so as to facilitate the removal of the infusion bag;

[0042] The infusion bag with the needle inserted is placed on the holder 98 with the needle at the notch. The needle removal motor 910 of the needle removal device 9 drives the movable plate 95 to rotate, clamping and fixing the needle on the fixed plate 97. Then, the retraction of the needle removal electric push rod 91 drives the needle removal seat 94 to move to the right, pulling the needle out of the infusion bag and positioning it above the needle groove 13. The needle removal motor 910 drives the movable plate 95 to rotate and separate it from the fixed plate 97, releasing the clamp on the needle. The needle falls into the sharps box 6 for collection under gravity, thus realizing the automatic separation and collection of the needle, avoiding hand contact operation, preventing needle pricks, and reducing workload through automated operation.

[0043] Example 2:

[0044] According to Embodiment 1, after the needle is removed from the infusion bag, the horizontal position of the movable plate 95 and the fixed plate 97 ensures that the needle will not easily fall off even if the movable plate 95 and the fixed plate 97 are separated and released from their clamping position. Therefore, in this embodiment, the following design is implemented:

[0045] Please see Figure 1-8The needle puller 9 includes a retainer 98, a movable plate 95, a fixed plate 97, a needle puller seat 94, a connecting seat 93, and a rotating motor 92. The rotating motor 92 is slidably mounted on the housing 1, and a needle puller electric push rod 91 is fixedly mounted on the housing 1 to drive the rotating motor 92 to slide. The needle puller seat 94 is connected to the rotating motor 92 through the connecting seat 93. Two meshing gears are rotatably arranged inside the connecting seat 93. The connecting seat 93 is fixedly mounted on the rotating motor 92, and the output shaft of the rotating motor 92 is movably inserted into the connecting seat 93 and coaxially fixedly connected to one of the gears. A connecting rod is fixedly arranged at the rear end of the needle puller seat 94. The connecting rod is inserted into the connecting seat 93 and coaxially fixedly connected to the other gear. The rotating motor 92 drives the two gears to rotate, thereby driving the connecting rod to rotate, controlling the rotation of the needle puller seat 94, thereby causing the movable plate 95 and the fixed plate 97 to rotate and tilt, so that the needle after being released from the clamp can easily fall into the sharps box 6 for collection under the action of gravity.

[0046] Example 3:

[0047] According to Examples 1-2, to prevent the needle from falling out of the sharps container 6 due to unexpected circumstances during use, the following design is implemented:

[0048] Please see Figure 1-8 The housing 1 is equipped with a shield 8, which includes a shielding electric push rod 81 and a shielding plate 82. The shielding electric push rod 81 is fixedly installed inside the housing 1, and the shielding plate 82 is fixedly connected to the extended end of the shielding electric push rod 81. The extension of the shielding electric push rod 81 drives the shielding plate 82 to slide and shield the area above the needle groove 13, preventing the needle from falling out.

[0049] In this embodiment, to prevent the sharps container 6 from lacking a locking mechanism and easily slipping out of the needle slot 13, causing the needle to fall out, the following design is implemented:

[0050] A pin 15 is provided on the housing 1 at the position where the sharps box 6 slides and separates from the housing 1. The pin 15 is connected to the housing 1 by an elastic element 16. Under the action of the elastic element 16, the pin 15 slides to block the sharps box 6 and restricts the sharps box 6 within the needle groove 13.

[0051] In this embodiment, in order to facilitate the movement of the box 1, several casters 2 are provided at the bottom of the box 1.

[0052] Example 4:

[0053] Please refer to Examples 1-3. Figure 1-8To achieve automatic control of needle removal and shearing, a pedal controller 3 is installed on one side of the housing 1, and a control panel is installed on the housing 1 to control the operation of the shearing electric push rod 71, the blocking electric push rod 81, the needle removal electric push rod 91, the rotating motor 92, and the needle removal motor 910. When the pedal controller 3 is pressed, the following actions are performed in sequence:

[0054] 1) The needle-pulling motor 910 drives the movable plate 95 to rotate, clamping and fixing the needle tip on the fixed plate 97;

[0055] 2) The extension of the shearing electric actuator 71 controls the front end of the movable shear plate 72 to rotate and cooperate with the fixed shear plate 73 to cut the infusion tube;

[0056] 3) The retraction of the needle removal electric push rod 91 drives the needle removal seat 94 to move to the right, pulling the needle out of the infusion bag and positioning it above the needle groove 13;

[0057] 4) Rotating motor 92 drives needle removal seat 94 to rotate, causing movable plate 95 and fixed plate 97 to rotate and tilt;

[0058] 5) The needle removal motor 910 drives the movable plate 95 to rotate and separate from the fixed plate 97, releasing the clamp on the needle and allowing the needle to fall into the sharps box 6 for collection under the action of gravity.

[0059] 6) Rotate motor 92 to drive needle removal seat 94 to rotate, causing movable plate 95 and fixed plate 97 to return to their original positions;

[0060] 7) The extension of the needle-pulling electric actuator 91 causes the needle-pulling seat 94 to move to the left and stick to the card holder 98;

[0061] 8) The retraction control of the shearing electric actuator 71 causes the front end of the movable shear plate 72 to rotate back to its original position.

[0062] To achieve the above actions, a control system was designed and installed on the control panel. The control system first controls the needle-pulling motor 910 to drive the movable plate 95 to rotate, clamping and fixing the needle onto the fixed plate 97; then it controls the extension of the shearing electric actuator 71 to control the front end of the movable shearing plate 72 to rotate in conjunction with the fixed shearing plate 73 to cut the infusion tube; next, it controls the retraction of the needle-pulling electric actuator 91 to move the needle-pulling seat 94 to the right, pulling the needle out of the infusion bag and positioning it above the needle groove 13; finally, it controls the rotation motor 92 to drive the needle-pulling seat 94 to rotate. The movable plate 95 and the fixed plate 97 are rotated and tilted. Then, the needle removal motor 910 is controlled to drive the movable plate 95 to rotate and separate from the fixed plate 97, releasing the clamp on the needle and allowing the needle to fall into the sharps box 6 for collection under gravity. Then, the rotation motor 92 is controlled to drive the needle removal seat 94 to rotate, causing the movable plate 95 and the fixed plate 97 to return to their original positions. Then, the extension of the needle removal electric push rod 91 is controlled to drive the needle removal seat 94 to move to the left and stick to the card holder 98. Then, the retraction of the shearing electric push rod 71 is controlled to control the front end of the movable shear plate 72 to rotate back to its original position.

[0063] Furthermore, the control system includes a fixing module, a cutting module, and a needle removal module;

[0064] The fixing module is used to control the needle-pulling motor 910 to drive the movable plate 95 to rotate and to fit or separate from the fixing plate 97.

[0065] The shearing module is used to control the extension of the shearing electric push rod 71 to drive the front end of the movable shear plate 72 to rotate closer to the fixed shear plate 73, or to control the retraction of the shearing electric push rod 71 to drive the front end of the movable shear plate 72 to rotate away from the fixed shear plate 73.

[0066] The needle removal module is used to control the retraction of the needle removal electric push rod 91 to move the needle removal seat 94 to the right and above the needle groove 13, or to control the extension of the needle removal electric push rod 91 to move the needle removal seat 94 to the left and stick to the card holder 98.
