Description

Technical Field

[0001] The invention relates to the technical field of medical solid waste treatment, and more particularly to a harmless treatment device for discarded syringes. Background Art

[0002] The device for handling discarded syringes is an important equipment in the field of medical waste treatment. Its function is to safely and efficiently handle discarded syringes to prevent them from causing harm to personnel, being illegally recycled by illegal personnel, causing secondary spread of diseases, and becoming a potential source of pollution. With the continuous development of medical technology and the improvement of medical waste treatment requirements, the application prospects of the device for handling discarded syringes are becoming more and more broad. In the future, such devices will be more harmless, automated, and environmentally friendly, especially providing a safer, more efficient, and more convenient way to handle medical solid waste.

[0003] Existing waste syringe processing devices usually combine multiple processing technologies, and their working process is basically as follows: the syringe enters the device in a vertical posture, and the needle of the waste syringe is separated from the syringe tube by a cutting knife, or the entire syringe is chopped up. The device is manually operated during operation, and some devices later developed into automatic cutting. The driving force includes motors, current control, etc., and then the fragments are disinfected. The disinfection methods include ultraviolet irradiation, high-temperature disinfection, and disinfectant soaking. The waste after the crushing process is further processed or disposed of, such as incineration, deep burial, etc., which can basically achieve the treatment of waste syringes, but there are still some problems.

[0004] In the analysis of the existing oral spray devices, it can be found that the traditional waste syringe processing devices have the following problems: first, there is the problem of classified collection. When the entire syringe is shredded, the needle part and the injection tube part are mixed, which is not easy to carry out subsequent processing. During the processing, the needle still has a large lateral volume, which is not easy to transport and transfer, and there is a risk of injury to the staff; secondly, there are holes inside the syringe, and the material is mostly plastic parts with strong toughness. When it is crushed by a hammer crusher or a shear crusher, the fragments with the injection tube will collapse everywhere, and the fragments remaining inside the device are not easy to clean, and it is not easy to collect and process later.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The harmless disposal device for discarded syringes involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2 The present invention provides a harmless treatment device for discarded syringes, comprising a housing component 1 and a syringe to be treated 7, wherein the housing component 1 comprises an external protective shell 101, a positioning component 2 is installed above the interior of the external protective shell 101, a separation component 3 is installed on the right side of the positioning component 2, a crushing and aggregating component 4 is installed below the positioning component 2, a disinfection and stirring component 5 is installed below the crushing and aggregating component 4, and a filtering and collecting component 6 is installed below the disinfection and stirring component 5;

[0030] In this embodiment, it should be specifically explained that: the external protective shell 101 separates the internal space of the device from the outside, the user puts the syringe to be processed 7 into the interior of the positioning component 2, the syringe to be processed 7 is first positioned by the positioning component 2, and then the separation component 3 processes the tip part of the syringe to be processed 7, and then the syringe to be processed reaches the position of the crushing and aggregation component 4 and is crushed, the residue is gathered by the crushing and aggregation component 4, and is transported to the interior of the disinfection and stirring component 5 for disinfection and residue stirring, and finally filtered and recovered by the filtering and collecting component 6, completing the harmless treatment of the syringe to be processed 7.

[0031] The main difference between this embodiment and the prior art is that in this embodiment, the syringe to be processed 7 is made to enter the processing area in a horizontal posture, and a processing method of first positioning and then separating is adopted, specifically, the positioning component 2 and the separation component 3;

[0032] The above structure is the main structure of this embodiment, which solves the problem of pollution caused by discarded syringes and retained needles that hurt people.

[0033] Reference Figure 3 The positioning component 2 includes a throwing port 201, a rail receiving plate 202 is installed below the throwing port 201, a track baffle 205 is installed above the rail receiving plate 202, a movable push plate 204 is installed in the middle of the rail receiving plate 202, one end of the rail receiving plate 202 is installed on the inner side of the external protective shell 101, and a front end flap 206 is installed on the other end of the rail receiving plate 202. The front end flap 206 performs a flipping action under the drive of the control device, and an infrared sensor 203 is installed directly above the front end flap 206. The infrared sensor 203 is installed below the inside of the external protective shell 101, and the infrared sensor 203 can control the movement of the movable push plate 204. A blocking baffle 102 is installed at one end of the front end flap 206 away from the rail receiving plate 202, and the top of the blocking baffle 102 is connected to the external protective shell 101.

[0034] In this embodiment, it is necessary to specifically explain that: the user throws the syringe to be processed 7 from the upper end of the throwing port 201 into the inside of the throwing port 201, and the syringe to be processed 7 slides from the inside of the throwing port 201 to the top of the track receiving plate 202 and the front end flap 206, and the track baffle 205 limits the syringe to be processed 7 to prevent the syringe to be processed 7 from shifting left and right, and the infrared sensor 203 recognizes the change of the infrared reflected light from below, and the infrared sensor 203 controls the moving push plate 204 to move toward the direction of the front end flap 206, and the moving push plate 204 contacts the tail of the syringe to be processed 7 and pushes the syringe to be processed 7 toward the direction of the front end flap 206, so that the top of the syringe to be processed 7 is fixed inside the positioning baffle 102.

[0035] The infrared sensor 203 uses the thermoelectric effect to measure the temperature of the surface of the target object. When infrared radiation irradiates the target surface, the target surface absorbs the radiation and is heated, causing the surface temperature to rise. The thermocouple in the sensor detects the temperature difference between the target surface and the reference surface, thereby measuring the temperature of the target surface. The infrared sensor 203 can also use the photoelectric effect to determine the properties and thickness of the target surface by measuring the reflectivity and transmittance of the object to the light, so as to take corresponding actions. The infrared sensor 203 can also emit infrared rays. Due to the obstruction of the object, the light is reflected to the infrared receiving tube, and the signal processed by the microcomputer in the integrated circuit is sent to the control device, thereby realizing the control function. Therefore, the infrared sensor 203 is an existing structure, and the specific structure and connection method of the infrared sensor 203 are not described in detail in this embodiment.

[0036] Reference Figure 4 and Figure 5 The syringe to be processed 7 includes a syringe to be processed 701 and a needle to be processed 702. A connecting cover 207 is installed inside the positioning baffle 102. The connecting cover 207 is a metal mesh structure. The syringe to be processed 7 is positioned above the front end flap 206. The syringe to be processed 701 is located on the side of the positioning baffle 102 close to the front end flap 206. The needle to be processed 702 passes through the connecting cover 207 to reach the side of the positioning baffle 102 away from the front end flap 206. A driving gear 301 is installed on the side of the positioning baffle 102 away from the front end flap 206. A clamping plate 3011 is installed on the driving gear 301. There are two clamping plates 3011. The two clamping plates 3011 are installed in parallel and open between them. A flexible electrode is provided, and a distance greater than the diameter of the needle 702 to be processed is left between the two. A conical wheel 302 is installed on the side of the driving gear 301 close to the blocking baffle 102, and the conical wheel 302 is meshed with the driving gear 301. A transmission gear 303 is installed on the side of the conical wheel 302 close to the needle 702 to be processed, and the conical wheel 302 is meshed with the transmission gear 303. A perforated gear 304 is installed on one end of the transmission gear 303 close to the needle 702 to be processed, and the transmission gear 303 is meshed with the perforated gear 304. A hole is opened in the center of the perforated gear 304 so that the needle 702 to be processed can pass through the perforated gear 304. A hot air gun 305 is installed on the side of the perforated gear 304 close to the connecting cover 207.

[0037] In this embodiment, it is necessary to specifically explain that: the syringe 7 to be processed moves toward the blocking baffle 102 under the push of the moving push plate 204, and finally the needle 702 to be processed passes through the connecting cover 207 and reaches between the two clamping plates 3011. The connection between the syringe 701 to be processed and the needle 702 to be processed is located inside the connecting cover 207. The needle 702 to be processed contacts the flexible electrode on the clamping plate 3011, so that the hot air gun 305 starts to work, and at the same time, the driving gear 301 rotates counterclockwise, and the driving gear 301 drives the clamping plate 3011 and the conical wheel 302 to rotate, and the rotation of the conical wheel 302 drives the transmission The moving gear 303 rotates, and the rotation of the transmission gear 303 drives the perforated gear 304 to rotate, so that the hot air gun 305 evenly heats the connection between the injection tube 701 to be treated and the needle 702 to be treated, so that the plastic at this position is softened. At the same time, due to the downward displacement of the position of the clamping plate 3011, a downward pulling force is applied to the needle 702 to be treated. Driven by the clamping plate 3011, the needle 702 to be treated is bent and deformed. When the driving gear 301 rotates one hundred and eighty degrees, the needle 702 to be treated will be separated from the injection tube 701 to be treated due to the pulling force, and then the driving gear 301 returns to the initial position under the control of the motor.

[0038] The material of the needle 702 to be processed is mainly stainless steel, and a few are titanium alloy and nickel-titanium alloy. These metals have good electrical conductivity. Therefore, when the needle 702 to be processed contacts the electrode installed on the clamping plate 3011, it can support the circuit to be turned on. The hot air gun 305 is an existing structure. The specific working circuit and connection method of the hot air gun 305 are not described in detail in this embodiment. In addition, the control device of the driving gear 301 also belongs to the existing technology. Therefore, this application does not make detailed limitations.

[0039] Reference Figure 6 A collecting box bottom plate 103 is installed at the bottom of the blocking baffle 102, and one end of the collecting box bottom plate 103 away from the blocking baffle 102 is connected to the external protective shell 101, and a needle collecting box 306 is installed above the collecting box bottom plate 103, and the needle collecting box 306 can slide on the collecting box bottom plate 103, and a cutting drive motor 401 is installed on the inner side of the external protective shell 101, and the cutting drive motor 401 is located below the collecting box bottom plate 103, and a transmission rod 402 is installed on the side of the cutting drive motor 401 away from the external protective shell 101, and the number of the cutting drive motor 401 and the transmission rod 402 are both two, and a plurality of cutting blades 403 are installed on the transmission rod 402, and the cutting blades 403 are distributed at intervals, and the shape of the cutting blades 403 is arc-shaped.

[0040] In this embodiment, it is necessary to specifically explain that: after the needle 702 to be processed is separated from the injection tube 701 to be processed, the needle 702 to be processed naturally falls into the needle collection box 306, and the needle collection box 306 can be pulled out from the outside to facilitate the transfer of the needle 702 to be processed collected inside; then the front flap 206 is turned over, and the injection tube 701 to be processed falls from above the front flap 206 to above the cutting blade 403. The spacing distribution and arc design of the cutting blade 403 can make the cutting blade 403 on the injection tube 701 to be processed 1 is fully squeezed without causing the injection tube 701 to slip; the operation of the cutting drive motor 401 drives the transmission rod 402 to rotate, and the rotation of the transmission rod 402 drives the cutting blade 403 to rotate, and the cutting blade 403 applies a shear force to the injection tube 701 to be processed, and then the injection tube 701 to be processed is crushed into block-like debris. After the injection tube 701 to be processed falls, the front end flap 206 flips back to the initial position, and the infrared sensor 203 senses a normal infrared signal, and controls the moving push plate 204 to return to the left position below the throwing port 201.

[0041] Reference Figure 7 A telescopic cylinder 404 is installed below the cutting drive motor 401, a gathering area bottom plate 104 is installed on the inner wall of the external protective shell 101, and the gathering area bottom plate 104 is located below the telescopic cylinder 404. A gathering funnel 409 is installed at one end of the gathering area bottom plate 104 away from the external protective shell 101, and a disinfection area baffle 105 is installed on the side of the gathering funnel 409 away from the gathering area bottom plate 104. A displacement spring 406 is installed above the gathering area bottom plate 104. There are several displacement springs 406. A chip receiving plate 408 is installed on the side, a push plate 407 is installed on the side of the chip receiving plate 408 close to the telescopic cylinder 404, a switch electrode 405 is installed on the lower end of the push plate 407, another switch electrode 405 is installed on the inner wall of the external protective shell 101 and is located below the telescopic cylinder 404, the push plate 407 can slide left and right on the chip receiving plate 408, and the push plate 407 and the telescopic cylinder 404 are slidably connected, and the telescopic cylinder 404 can slide up and down on the side of the push plate 407 close to the telescopic cylinder 404.

[0042] In this embodiment, it is necessary to specifically explain that: after the injection tube 701 to be processed is crushed, its fragments will fall on the fragment receiving plate 408. Due to the gravity of the fragments, the fragment receiving plate 408 will compress the displacement spring 406 downward, driving the push plate 407 to descend. The descent of the push plate 407 drives the on-off electrode 405 to descend. After that, the on-off electrode 405 installed on the push plate 407 will contact the on-off electrode 405 installed on the inner wall of the external protective shell 101, and the drive circuit of the telescopic cylinder 404 will be turned on, and the telescopic cylinder 404 extends, and the telescopic cylinder 404 pushes the push plate 407 to move away from the telescopic cylinder 404, so that the push plate 407 will push the fragments on the fragment receiving plate 408 to the top of the gathering funnel 409, and finally make the fragments fall into the gathering funnel 409, then, the pressure above the shift spring 406 is reduced, and the shift spring 406 re-extends, driving the fragment receiving plate 408 and the push plate 407 to return to the initial position, thereby driving the two on-off electrodes 405 to separate, and the telescopic cylinder 404 returns to the initial state.

[0043] Reference Figure 8 A transport pipe 501 is installed at the lower end of the gathering funnel 409, and the two ends of the transport pipe 501 are respectively connected to the disinfection area baffle 105 and the external protective shell 101, and an auger blade 502 is installed inside the transport pipe 501. The auger blade 502 is driven to rotate by a control device, and a disinfectant pump 504 is installed on the left side of the disinfection area baffle 105. A liquid transport pipe 503 is installed above the disinfectant pump 504. The upper end of the liquid transport pipe 503 is located inside the transport pipe 501, and an outlet is opened at the bottom of the transport pipe 501 near one end of the external protective shell 101.

[0044] In this embodiment, it is necessary to specifically explain that: when the fragments of the injection tube 701 to be processed are pushed into the gathering funnel 409, the fragments are gathered inside the gathering funnel 409 and are concentratedly sent to the inside of the transport pipe 501. At the same time, the disinfectant pump 504 allows the disinfectant to be transported to the inside of the transport pipe 501 through the liquid delivery pipe 503. The auger blades 502 rotate under the drive of the control device. The auger blades 502 mix the fragments and the disinfectant and grind the fragments again during stirring. The mixture of the fragments and the disinfectant is sent to one end of the transport pipe 501 close to the external protective shell 101, and finally falls from the outlet opened at the bottom of the transport pipe 501 to the top of the filter collection component 6.

[0045] Reference Fig. 9The filtering and collecting assembly 6 comprises a swinging receiving plate 601, which is slidably connected to the inner wall of the outer protective shell 101, a cam assembly 602 is installed at the front end of the swinging receiving plate 601, and a spring is provided at the rear end of the swinging receiving plate 601 so that the swinging receiving plate 601 can maintain contact with the cam assembly 602, a solid sliding plate 603 is installed at the rear end of the inner wall of the outer protective shell 101, and a plurality of filtering holes are provided inside the swinging receiving plate 601 and the solid sliding plate 603, a debris collection area 604 is installed below the solid sliding plate 603, the debris collection area 604 is slidably connected to the outer protective shell 101, and a waste liquid transfer port 605 is installed at the bottom of the outer protective shell 101.

[0046] In this embodiment, it is necessary to specifically explain that: when the fragments of the injection tube 701 to be processed fall from the outlet of the transport pipe 501, the swing receiving plate 601 receives the mixture of the fragments and the disinfectant, and the cam assembly 602 rotates to make the swing receiving plate 601 swing back and forth, thereby accelerating the disinfectant and the original liquid inside the injection tube 701 to be processed to flow downward from the filter holes of the swing receiving plate 601. At the same time, due to the inclined angle of the swing receiving plate 601, the fragments slide further downward during the shaking and reach the top of the solid sliding plate 603. The liquid remaining on the fragments is further filtered downward through the filter holes of the solid sliding plate 603. The fragments slide further down and are finally collected in the debris collection area 604. The debris collection area 604 can be pulled out from the outside of the device to facilitate the transfer of the collected fragments. At the same time, the waste liquid collected at the bottom of the external protective shell 101 can be transferred out of the device through the waste liquid transfer port 605.

[0047] Working principle of the present invention:

[0048] The main problem solved by this embodiment is that: the device is provided with a clamping plate 3011 and a hot air gun 305, and utilizes the property that plastic is easily softened by heat and the conductivity of stainless steel to make it easy to separate the connection between the needle 702 to be processed and the injection tube 701 to be processed. At the same time, the needle 702 to be processed is deformed and bent in the process of the clamping plate 3011 pulling the needle 702 to be processed, and finally collected by the needle collection box 306, thereby reducing the lateral volume of the needles and solving the problem that the needle part of the discarded syringe is easy to stab people in the process of collection and processing;

[0049] Secondly, by providing a telescopic cylinder 404 and a shift spring 406, the gravity of the injection tube 701 to be processed is used to control the on-off of the working circuit of the telescopic cylinder 404, so that the crushing and gathering component 4 can automatically push the crushed fragments of the injection tube 701 to be processed into the gathering funnel 409, preventing the fragments generated during the extrusion and crushing of the injection tube 701 to be processed from falling everywhere, thereby solving the problem that the fragments generated after the injection tube 701 to be processed are too scattered and difficult to collect.

[0050] The specific steps are as follows: first, place the device in a flat and open area, then throw the syringe 7 to be processed from the upper end of the throwing port 201 into the inside of the throwing port 201, and the syringe 7 to be processed will slide from the inside of the throwing port 201 to the top of the track receiving plate 202 and the front end flap 206. Under the guidance of the track baffle 205, the syringe 7 to be processed will remain in the center line position of the front end flap 206 without shifting left or right. The infrared sensor 203 recognizes the change of the infrared reflected light from below, so the infrared sensor 203 controls the moving push plate 204 to move toward the front end flap 206, and the moving push plate 204 contacts the tail of the syringe 701 to be processed, and pushes the syringe 7 to be processed toward the front end flap 206, and finally makes the connection between the needle 702 to be processed and the syringe 701 to be processed press against the inside of the connecting cover 207;

[0051] The needle 702 to be processed passes through the central hole of the connecting cover 207 and the perforated gear 304, and arrives between the two clamping plates 3011. The needle 702 to be processed contacts the flexible electrode provided on the clamping plate 3011, so that the hot air gun 305 starts to work, and at the same time, the driving gear 301 rotates counterclockwise, and the driving gear 301 drives the clamping plate 3011 and the conical wheel 302 to rotate. The rotation of the conical wheel 302 changes the rotation direction, so that the transmission gear 303 rotates. The rotation of the transmission gear 303 drives the perforated gear 304 to rotate. The rotation of the perforated gear 304 causes the hot air gun 305 to rotate around the injection tube 701 to be processed and the needle to be processed. The connection of 702 is heated evenly, so that the plastic at this position is softened by heat. At the same time, due to the downward displacement of the position of the clamping plate 3011, a downward pulling force is applied to the needle 702 to be processed. Under the clamping and driving of the clamping plate 3011, the needle 702 to be processed is bent and deformed. When the driving gear 301 rotates 180 degrees, the needle 702 to be processed is separated from the injection tube 701 to be processed due to the pulling force. Then, under the control of the motor, the driving gear 301 returns to the initial position, and the needle 702 to be processed naturally falls into the inside of the needle collection box 306. The staff can draw out the needle collection box 306 from the outside of the device to transfer the collected needles 702 to be processed.

[0052] After the driving gear 301 rotates 180 degrees, the front flap 206 flips over, and the syringe 701 to be processed falls from the top of the front flap 206 to the top of the cutting blade 403. The operation of the cutting drive motor 401 drives the transmission rod 402 to rotate, and the rotation of the transmission rod 402 drives the cutting blade 403 to rotate. The cutting blade 403 applies a shear force to the syringe 701 to be processed, and then the syringe 701 to be processed is crushed into block-like debris. After the syringe 701 to be processed falls from the top of the front flap 206, the front flap 206 flips back to the initial position, and the infrared sensor 203 senses a normal infrared signal, controls the moving push plate 204 to return to the left position below the throwing port 201, and waits for the next syringe 7 to be processed to be above the track baffle 205;

[0053] When the injection tube 701 to be processed is crushed, its fragments will fall on the fragment receiving plate 408. The gravity of the fragments themselves presses the fragment receiving plate 408 downward, and the fragment receiving plate 408 compresses the displacement spring 406 downward, driving the push plate 407 to descend. The descent of the push plate 407 drives the on-off electrode 405 to descend, and then the on-off electrode 405 installed on the push plate 407 will contact the on-off electrode 405 installed on the inner wall of the external protective shell 101, and the drive circuit of the telescopic cylinder 404 is turned on, and the telescopic cylinder 40 4 extends, the telescopic cylinder 404 pushes the push plate 407 to move away from the telescopic cylinder 404, so that the push plate 407 pushes the fragments on the fragment receiving plate 408 to the top of the gathering funnel 409, and finally makes the fragments fall into the gathering funnel 409, then, the pressure above the shift spring 406 is reduced, and the shift spring 406 re-extends, driving the fragment receiving plate 408 and the push plate 407 back to the initial position, thereby driving the two on-off electrodes 405 to separate, and the telescopic cylinder 404 returns to the initial state;

[0054] The fragments of the injection tube 701 to be processed are pushed into the gathering funnel 409, where the fragments are gathered inside the gathering funnel 409 and sent to the inside of the transport pipe 501. At the same time, the disinfectant pump 504 absorbs the disinfectant, so that the disinfectant is transported to the inside of the transport pipe 501 through the liquid transport pipe 503. The auger blades 502 rotate under the drive of the control device, and the auger blades 502 mix the fragments and the disinfectant, and grind the fragments again during the stirring, and send the mixture of the fragments and the disinfectant from one end close to the gathering funnel 409 to one end close to the external protective shell 101, and finally fall from the outlet opened below the transport pipe 501 to the top of the filter collection component 6;

[0055] The fragments of the injection tube 701 to be processed fall from the outlet of the transport pipe 501 and fall above the swing receiving plate 601. The rotation of the cam assembly 602 causes the swing receiving plate 601 to swing back and forth, thereby accelerating the disinfectant and the liquid remaining inside the injection tube 701 to be processed to flow from the filter holes of the swing receiving plate 601 to the lower area. At the same time, due to the inclined angle of the swing receiving plate 601, the fragments slide further downward during the shaking and reach the top of the solid sliding plate 603. The liquid remaining on the fragments is further filtered to the bottom through the filter holes of the solid sliding plate 603. The fragments slide further down and are finally collected in the debris collection area 604. The staff can pull the debris collection area 604 out from the outside of the device to transfer the collected fragments, and at the same time transfer the waste liquid collected at the bottom of the external protective shell 101 from the inside of the device through the waste liquid transfer port 605.
