[0002] The use of disposable syringes can effectively prevent and control hospital infections, improve work efficiency and medical quality, and has been applied in clinical practice. How to deal with disposable syringes after use has become an important issue in hospital management. To this end, the state has formulated a series of regulations and standards for control, which has played a positive role in preventing the spread of pathogenic microorganisms and preventing waste from entering the society and causing secondary pollution. However, it also increases the chances of needlestick injuries and contamination of nurses. Therefore, it is important to choose a scientific treatment method. The emergence of automated dispensing has increased the number of syringes used for dispensing, resulting in a significant increase in the amount of syringes processed. At present, there are related processing equipment on the market, such as the invention patent with patent number CN112843390A, which discloses a needle and tube separation device for syringe destruction. It uses a limit plate to limit the syringe, and the limit block is stuck in the needle groove. When the push rod moves, the limit block moves to peel off the needle. It has higher requirements for the installation of the syringe, that is, it needs to be installed in a specific position to achieve the limit block aligning with the needle groove, and then separation, which increases the installation requirements and reduces the processing efficiency. The above problems need to be solved urgently. Summary of the invention

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the protection scope of the present application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0031] Referring to "embodiment" herein means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] The following will refer to the accompanying drawings to detail a waste syringe treatment device of the present invention.

[0033] As Figure 1As shown, a discarded syringe processing device includes a needle clamping device 1, a syringe clamping device 2 and a stretching assembly 3; the syringe clamping device 2 includes a second clamping assembly 21, and the second clamping assembly 21 is used to clamp the syringe A; the needle clamping device 1 includes a first clamping device 13; the first clamping device 13 can move toward the second clamping assembly 21 so that the stretching assembly 3 stretches the second clamping assembly 21, and the first clamping device 13 clamps the syringe A and is pulled out of the second clamping assembly 21. Preferably, the second clamping assembly 21 is composed of two groups; based on the setting of the syringe clamping device 2 and the stretching assembly 3, when processing the discarded syringe A, the syringe A can be placed in the syringe clamping device 2, and the stretching assembly 3 stretches the second clamping assembly 21 during the movement of the first clamping device 13 toward the second clamping assembly 21. The first clamping device 13 clamps the syringe A and drives the syringe A to separate from the second clamping assembly 21; thus, there is no need to clamp the syringe A on the first clamping device 13, and the installation and subsequent processing are separated, which facilitates the installation of the syringe A and improves the processing efficiency.

[0034] The discarded syringe processing device of the present invention is based on a clamping device to clamp off the needle. It is not only suitable for syringes with separated needles and syringes, but also suitable for syringes with integrated needles and syringes. It has a wider range of applications, and based on the syringe clamping device 2, it is convenient to install the syringe A and improve the processing efficiency.

[0035] In some embodiments, Figure 2 As shown, the needle pinching device 1 also includes a workbench 11, a pinching device 12, a first clamping device 13 and a waste recovery device 14; the pinching device 12 and the first clamping device 13 are respectively installed on the workbench 11; the first clamping device 13 is used to clamp the syringe of the syringe A; the pinching device 12 is used to pinch off the needle of the syringe A, and the needle falls into the needle recovery funnel 122 of the pinching device 12, and the needle recovery funnel 122 can move and automatically unload; the waste recovery device 14 is used to receive the syringe and needle after the syringe A is separated; preferably, the first clamping device 13 is two groups.

[0036] Exemplarily, the waste recovery device 14 is a waste box, which is arranged under the workbench 11; and the top is open, and has a needle recovery port and a syringe recovery port, and the needles and syringes are recovered respectively; if the waste recovery device 14 is configured to include a needle recovery box 141 and a syringe recovery box 142; wherein the first clamping device 13 loosens the syringe to release the syringe so that it falls into the middle syringe recovery box 142 of the waste recovery device 14; the needle recovery funnel 122 unloads the needle into the needle recovery box 141 when unloading.

[0037] The waste syringe disposal device of the present invention clamps the needle based on a clamping device, and is applicable not only to syringes with separable needles and barrels, but also to syringes with integrated needles and barrels, with a wider scope of application. By providing a needle recovery funnel for automatic discharging, it avoids human contact with the needle. Thus, the probability of harm and pollution to the staff is reduced. Moreover, the clamped needle cannot be reused to avoid secondary pollution. And based on the setting of the needle recovery funnel, it is avoided that the residual liquid in syringe A after cutting drips to the outside and pollutes the environment.

[0038] In some embodiments, as Figure 3 and 4 shown, a movable door panel 1224 is provided on the side of the needle recovery funnel 122. When the syringe A moves, the needle of the syringe A can enter the needle recovery funnel 122 through the movable door panel 1224. Exemplarily, the movable door panel 1224 is rotatably installed on the needle recovery funnel 122, and the rotation direction is towards the inside of the needle recovery funnel 122, and is reset by a return spring (that is, the movable door panel 1224 resets and closes after the needle enters the needle recovery funnel 122), and the original state of the movable door panel 1224 is the closed state. Based on the setting of the movable door panel 1224, when placing the syringe, it can be placed from one side of the first clamping device 13. During the process of placing the syringe A, the needle part of the syringe A enters the needle recovery funnel 122 through the movable door panel 1224. Thus, on the one hand, it is avoided that the needle falls outside the needle recovery funnel 122 after being cut; on the other hand, it is also more convenient to place the needle in the first clamping device 13 (when the movable door panel 1224 is not provided on the needle recovery funnel 122, to place the needle in the needle recovery funnel 122, the syringe A needs to be first moved to the opened first clamping device 13 and then moved downward so that the needle of the syringe A moves into the needle recovery funnel 122).

[0039] Preferably, the surface of the movable door panel 1224 adjacent to the main body of the needle recovery funnel 122 is inclined to form a flared structure facing the outside of the needle recovery funnel 122. Based on the flared structure, it is convenient to place the needle part into the needle recovery funnel 122.

[0040] In some embodiments, as Figure 2 and 5As shown in the figure, the clamping device 12 includes a pair of scissors assembly 121 (which can be an electric or pneumatic scissors, such as the NY-10 pneumatic scissors), a needle recovery funnel 122, and a first moving device 123 (which can be a linear module or a slider-type electric cylinder, such as the ETB5-X40-400-BM-P10-C4); the needle recovery funnel 122 is located below the pair of scissors 1211 of the pair of scissors assembly 121; preferably, the first moving device 123 drives the needle recovery funnel 122 and the pair of scissors assembly 121 to move simultaneously, such as installing the needle recovery funnel 122 on the pair of scissors assembly 121; to maintain the relative position of the two stable, so as to prevent the clamped needles from falling outside the needle recovery funnel 122 due to the change of the relative position.

[0041] The first moving device 123 drives the needle recovery funnel 122 to reciprocate between the material receiving position below the pair of scissors assembly 121 and the material discharging position above the waste recovery device 14; the needle recovery funnel 122 has a self-resetting bottom cover 1222. When the needle recovery funnel 122 moves to the material discharging position, the ejector rod 124 installed on the workbench 11 pushes open the bottom cover 1222 for discharging, and the bottom cover 1222 resets and closes after leaving the material discharging position (such as the bottom cover 1222 is rotatably connected to the main body of the needle recovery funnel 122, and the ejector rod 124 pushes to make the bottom cover 1222 rotate to open, or, such as the bottom cover 1222 can be slidably inserted and connected to the main body of the needle recovery funnel 122, and the ejector rod 124 pushes to make the bottom cover 1222 move to open).

[0042] The needle recovery funnel 122 in the present invention, as Figure 2-4 shown, includes a funnel cylinder 1221, a bottom cover 1222, and a return spring 1223; the funnel cylinder 1221 has openings at the top and bottom; the bottom cover 1222 includes a cover plate 12221 and a top plate 12222; the cover plate 12221 covers the bottom opening of the funnel cylinder 1221 and is rotatably connected to the funnel cylinder 1221, and the rotation direction is towards the outside of the funnel cylinder 1221; the top plate 12222 is fixedly connected to the cover plate 12221 and the included angle with the cover plate 12221 is greater than zero (such as a 90-degree angle. At this time, it is advisable to open an opening on the side wall of the funnel cylinder 1221 that can accommodate the top plate 12222 to prevent the top plate 12222 from protruding from the funnel cylinder 1221 and causing accidental opening); the ejector rod 124 is located on the moving line of the top plate 12222. When the needle recovery funnel 122 moves to the material discharging position, the ejector rod 124 abuts against the top plate 12222 to make the cover plate 12221 rotate to open the bottom opening of the funnel cylinder 1221 for discharging; when the top plate 12222 disengages from the ejector rod 124, the bottom cover 1222 resets and closes through the return spring 1223; based on the setting of the rotation opening and closing of the bottom cover 1222, the sliding opening method, this method enables discharging to be completed with a smaller stroke (when the bottom cover 1222 opens, the cover plate 12221 is inclined. In this way, discharging can be completed without the cover plate 12221 being fully opened), improving the efficiency.

[0043] In some embodiments, such as Figure 2 and 5 shown, the first clamping device 13 includes a first clamping assembly 131 and a second moving device 132. The first clamping assembly 131 (such as a split jaw or a rotating and opening / closing jaw, such as the IAI electric gripper RCP6 RCP6-GRT7A-WA-28P-1-30-P5-R05-CJLB) clamps the barrel of the syringe A; the second moving device 132 (which can be selected as a structure where a motor drives a synchronous belt assembly to rotate and a slider is installed on the synchronous belt, or a linear module or a slider electric cylinder can be selected instead) drives the first clamping assembly 131 to reciprocate between the material taking position and the material discharging position. When at the material discharging position, the first clamping assembly 131 releases the syringe A so that the syringe A drops into the waste recycling device 14.

[0044] Exemplarily, the first clamping assembly 131 is a split jaw (such as the IAI electric gripper RCP6 RCP6-GRT7A-WA-28P-1-30-P5-R05-CJLB); the first clamping device 13 further includes a blocking member 133. The blocking member 133 is installed on the workbench 11 and blocks the moving path of the syringe A when the first clamping assembly 131 clamps the syringe A (specifically, it blocks the moving path of the syringe tail to avoid affecting the movement of the syringe body), so that after the first clamping assembly 131 releases the syringe A, the syringe A can disengage from the clamping opening direction of the first clamping assembly 131 (that is, disengage from the side of the first clamping assembly 131). Compared with the way that the first clamping assembly 131 releases the barrel to let the syringe drop freely, the side disengagement does not require the first clamping assembly 131 to open to the width of the widest part of the barrel (such as the position held by two fingers during injection), reducing the opening stroke of the first clamping assembly 131 and improving the discharging efficiency; the material taking position can be a position convenient for manual placement of the waste syringe A.

[0045] In some embodiments, such as Figure 1 , 6 and as shown in 8, the syringe clamping device 2 further includes a fixing block 22 at the tail of the syringe. The fixing block 22 is installed on the second clamping assembly 21 and has a groove adapted to the tail of the syringe A. When the second clamping assembly 21 clamps the syringe A, the tail of the syringe A is located in the groove (preferably, the groove is arranged on the side of the fixing block 22 and is adapted to the shape of the tail of the syringe A so that the tail of the syringe A can be hung on the fixing block 22 when placed in the groove); thus, the positioning placement of the syringe A makes the clamping position of the syringe A by the first clamping device 13 fixed, and further makes the clamping position of the needle by the clamping device 12 fixed.

[0046] Preferably, the clamping device 12 can move towards the second clamping assembly 21 simultaneously with the first clamping device 13; thus, the clamping device 12 can start the clamping operation after the first clamping device 13 stably clamps the syringe A, improving the efficiency.

[0047] In some embodiments, as Figure 6 and 7 shown, the second clamping assembly 21 includes second clamping arms 211, a first guiding member 212 (such as a slider-rail assembly), a reset member 213, and a mounting base 214; the first guiding member 212 is mounted on the mounting base 214; the second clamping arms 211 are arranged in pairs, and the paired second clamping arms 211 are oppositely arranged on the first guiding member 212 and can approach or separate from each other under the guidance of the first guiding member 212 (such as the rail is mounted on the mounting base 214, and each second clamping arm 211 is mounted on a slider); both sides of the reset member 213 are respectively connected to the opposite second clamping arms 211 to keep the second clamping arms 211 in contact with the syringe A; preferably, the reset member 213 is an elastic reset member (such as a spring or elastic rubber); based on the clamping of the syringe A by the second clamping arms 211, the first guiding member 212, and the reset member 213, no power element is required. It only needs to push the syringe A from one side of the second clamping arms 211 into the space between the second clamping arms 211 to complete the installation; especially when used in cooperation with the fixing block 22, it is not only convenient for the installation of the syringe A but also convenient for the positioning of the syringe A; preferably, the minimum distance between the opposite surfaces of the second clamping arms 211 decreases from the outside to the inside, that is, the ends between the second clamping arms 211 form a flared structure to facilitate the insertion of the syringe A.

[0048] In some embodiments, as Figure 7 shown, the second clamping assembly 21 further includes a limiting member 215; the limiting member 215 is arranged on the opposite surfaces of the second clamping arms 211, and the limiting member 215 restricts the syringe A from directly disengaging from the opening side formed by the second clamping arms 211; the limiting member 215 can be selected as an elastic member for limiting based on elastic deformation, or can be selected in the form of rotational limiting, that is, the limiting member 215 rotates to allow the syringe A to pass through, and rotates in the opposite direction after the syringe A passes through, thereby restricting the syringe A from disengaging.

[0049] Specifically, an installation groove 2111 is formed on the second clamping arm 211 of the present invention; the limiting members 215 are arranged in pairs and are in the structure of sector plates. The side of the center angle of the sector is located in the installation groove 2111 and is rotatably connected to the installation groove 2111. The side corresponding to the arc edge faces the inner side between the second clamping arms 211, and the rotation direction of the limiting member 215 faces the inside of the installation groove 2111; the limiting member 215 has a limiting position where it exposes the installation groove 2111 in the rotation direction and a release position where the minimum distance between the limiting members 215 increases after rotation to allow the syringe A to pass through, and the limiting member 215 is restored from the release position to the limiting position by the second return spring 216; based on the arrangement that the limiting members 215 are arranged in pairs and are in the structure of sector plates, after the syringe A is clamped, the second clamping arm 211 and the limiting member 215 jointly clamp the syringe A. Thus, the syringe A is more stable; and during the process of pushing the syringe A in, after the syringe A contacts the sector radius edge of the limiting member 215 and continues to move inward to squeeze the limiting member 215, the limiting member 215 rotates towards the installation groove 2111, and the distance between the limiting members 215 increases. After the syringe A passes through, the arc side surface of the restored sector of the limiting member 215 abuts against the syringe A to clamp the syringe A.

[0050] Preferably, the rotation angle of the limiting member 215 is limited by a rotation guiding member 217. For example, the rotation guiding member 217 is fixedly arranged on the limiting member 215, and guiding grooves 21111 are formed on the top surface and / or the bottom surface of the installation groove 2111, and the end of the rotation guiding member 217 is located in the guiding groove 21111; thus, excessive rotation of the limiting member 215 is avoided, and the limiting effect on the syringe A fails.

[0051] In some embodiments, as Figure 7 shown, the second clamping assembly 21 further includes a synchronization assembly 218; the synchronization assembly 218 includes a synchronization pulley 2181 and a synchronization belt 2182; the synchronization pulleys 2181 are arranged in pairs and are spacedly installed on the mounting seat 214; the synchronization belt 2182 is wound around the paired synchronization pulleys 2181, and the synchronization belt 2182 has a straight section parallel to the movement direction of the second clamping arm 211; each second clamping arm 211 is installed on the straight section of the synchronization belt 2182 on both sides of the synchronization pulley 2181; based on the synchronization assembly 218, it is ensured that the movement amounts of the two paired second clamping arms 211 are the same. Thus, it is ensured that the position of the syringe A is fixed in the clamped state. Furthermore, the clamping of the syringe A by the first clamping assembly is ensured to be stable. Specifically, the synchronization belt 2182 is a steel wire rope. Compared with a synchronization pulley, the steel wire rope has very little deformation in the low-speed state and higher stability.

[0052] In some embodiments, as Figure 1 and 6As shown in the figure, the spreading assembly 3 includes a spreading member 31 and a guiding member 32; the second clamping assembly 21 has a pair of second clamping arms 211 arranged oppositely, and the guiding member 32 is installed on each second clamping arm 211; the spreading member 31 is installed on the first clamping device 13 and can extend between the guiding members 32 and abut against the guiding members 32. The width of the part of the spreading member 31 extending into the guiding member 32 gradually increases from outside to inside (the specific increasing range can be selected according to the specifications of the syringe) to spread the second clamping arms 211. When there is a conflict between the spreading member 31 and the clamped syringe A, an avoidance opening can be provided on the spreading member 31 to avoid the syringe A; preferably, the guiding member 32 is a guiding wheel, and the wheel surface faces the spreading member 31.

[0053] The working process of the waste syringe treatment device of the present invention is as follows:

[0054] After the syringe A is installed on the syringe clamping device 2, the clamping scissors assembly 121 and the first clamping assembly 131 move towards the second clamping assembly 21 respectively driven by the first moving device 123 and the second moving device 132. When the spreading member 31 moves between the guiding members 32 and continues to move to spread the pair of second clamping arms 211 of the second clamping assembly 21, when the distance between the second clamping arms 211 is sufficient for the syringe A to break away, the first moving device 123 and the second moving device 132 stop moving. At this time, the syringe A is located between the clamping arms of the first clamping assembly 131, and the needle of the syringe A is located in the needle recovery funnel 122; then the first clamping assembly 131 acts to clamp the syringe A, and the first moving device 123 and the second moving device 132 act in the reverse direction to drive the clamping scissors assembly 121 and the first clamping assembly 131 to move simultaneously, taking the syringe A away from the second clamping assembly 2. The clamping scissors assembly 121 acts to cut off the needle part of the syringe A, and the cut-off needle drops into the needle recovery funnel 122. The first moving device 123 and the second moving device 132 continue to drive the clamping scissors assembly 121 and the first clamping assembly 131 to move. First, the ejector rod 124 contacts and opens the bottom cover 1222 of the barrel to discharge the needle into the needle recovery box 141 of the waste recovery device 14. The needle recovery funnel 122 continues to move to avoid the lower part of the syringe barrel clamped by the first clamping assembly 131. At this time, the limiting member 215 contacts the tail of the syringe A and the first clamping assembly 131 releases the syringe barrel. The first clamping assembly 131 continues to move so that the limiting member 215 blocks the tail of the syringe A and the syringe barrel breaks away from the first clamping assembly 131 and drops into the syringe barrel recovery box 142 of the waste recovery device 14 to complete the unloading, and then each device resets.
