Description

Technical Field

[0002] In the prior art, there is a patent document with the name of a deforming sharp container and the application number of 201520065202.4; in this patent document, through structures such as a blade holder for installing blades, an infusion tube fixing groove, and a sharp instrument fixing groove, the functions of cutting and separating a sharp instrument (essentially an infusion needle) and an infusion tube (essentially an infusion hose) and recycling them separately are achieved.

[0003] However, the above prior art does not perform a deforming operation on the sharp instrument itself. The essential reason is that in the above prior art, the blade can only cut the connection between the sharp instrument and the infusion tube, but cannot use the blade to deform the sharp instrument.

[0056] Embodiment 1:

[0057] In this embodiment, a recycling device for recycling infusion sets is provided to solve the technical problem of how to deform the infusion needles of the infusion sets.

[0058] Specifically, referring to Figures 1 to 11 , the recycling device for recycling infusion sets (hereinafter referred to as the recycling device) in this embodiment includes a compression mechanism 1, a push rod mechanism 2, and a reamer mechanism 3;

[0059] The compression mechanism 1 is provided with a sliding channel 110, a receiving channel 111, and a plurality of compression components 120. The sliding channel 110 communicates with the receiving channel 111, and the receiving channel 111 is restricted between the plurality of compression components 120;

[0060] The reamer mechanism 3 is provided with a rigid housing 311 and a plurality of reamers 312. Among them, a crushing cavity 313 is arranged inside the rigid housing 311, and the inner wall of the crusher is configured as a plurality of limiting surfaces 314. The contour of any one of the limiting surfaces 314 is respectively a part of a reference conical surface, and a preset angle is configured between two adjacent limiting surfaces 314. The plurality of reamers 312 are movably arranged in the crushing cavity 313;

[0061] The accommodating channel 111 has a first state with the maximum capacity and a second state with the minimum capacity. A plurality of compression components 120 are used to control the transformation of the accommodating channel 111 between the first state and the second state. Among them, the accommodating channel 111 in the second state is restricted by the plurality of compression components 120 into a strip-shaped channel;

[0062] The strip-shaped channel communicates with the crushing chamber 313, and the moving path of the push rod 210 of the push rod mechanism 2 is restricted between the strip-shaped channel and the crushing chamber 313.

[0063] The specific structure and function of the infusion set are common knowledge known to those skilled in the art. The infusion set is used together with an infusion bottle or an infusion bag in clinical practice, and the rest will not be elaborated here.

[0064] In the prior art, if the infusion needle of the infusion set is to be deformed, usually medical staff use special cutting pliers to manually operate and cut off the infusion set, so as to achieve the purpose of deforming the infusion needle; however, when using the cutting pliers to deform the infusion set, medical staff have to contact the infusion needle with their hands, which increases the risk of the infusion needle piercing into the hands of medical staff in some unexpected situations;

[0065] In some known prior arts, such as the deformation device for a syringe or the deformation device for an infusion set, etc., it is provided that the infusion needle can be automatically deformed, but still, the hands of medical staff need to contact the infusion needle, and medical staff need to insert the infusion needle into the designated position of the deformation device to achieve deformation; in other words, the risk of the infusion needle piercing into the hands of medical staff has not been eliminated yet.

[0066] Therefore, one of the design purposes of the recycling device for recycling the infusion set in this embodiment is to deform the infusion needle in an automatic manner, and the second design purpose is to reduce the contact between medical staff and the infusion needle.

[0067] When designing for the above design purposes, the first technical problem actually encountered is how to position the infusion needle and the reamer mechanism 3 so that the relatively fixed infusion needle can be deformed by the reamer mechanism 3.

[0068] In this embodiment, for the above first technical problem, a technical solution of arranging a plurality of limiting surfaces 314 inside the reamer mechanism 3 is specifically adopted;

[0069] Specifically, refer to Figures 3 to 6, the inner wall of the crushing chamber 313 is configured as a plurality of limiting surfaces 314, and the contour of each limiting surface 314 is respectively a part of a reference conical surface; in other words, the contour of each limiting surface 314 after being unfolded according to a plane presents as a part of a fan-shaped contour or an annular contour; the reason for such a setting is that by using the different angles of the conical surfaces where two adjacent limiting surfaces 314 are located, a preset angle state between two adjacent limiting surfaces 314 can be naturally formed;

[0070] It should be understood that the reference conical surface is a hypothetically existing conical surface, and the reference conical surface is used as a reference object to describe the shape or contour of the limiting surface 314; in other words, the limiting surface 314 is only a part of the reference conical surface. For example, on the conical surface of a cone, a cross-section is set between the cone bottom and the cone tip, and this cross-section is tangent to the axis line of the cone. At this time, the shape or contour of the frustum-shaped circumferential surface between the cross-section and the cone bottom is the contour of the limiting surface 314.

[0071] It should be understood that the preset angle should be understood as follows: two straight lines are formed at the intersection of the contour of any limiting surface 314 and the same reference cross-section, and these straight lines are defined as side lines. In two adjacent limiting surfaces 314, the angle formed by the side line of the first limiting surface 314 and the side line of the second limiting surface 314 (refer to Figure 6 the A position in) is the preset angle; further, from the direction in which the infusion needle contacts the limiting surface 314, the preset angle is greater than 90 degrees and less than 270 degrees.

[0072] While a preset angle is formed between two adjacent limiting surfaces 314, a plurality of reamers 312 of the reamer mechanism 3 are arranged in the crushing chamber 313, and the arrangement mode of the plurality of reamers 312 matches the arrangement mode of the plurality of limiting surfaces 314; specifically, when the plurality of reamers 312 are arranged in the crushing chamber 313, the gap between any one reamer 312 and the corresponding one of the limiting surfaces 314 is configured to be the same or approximately the same;

[0073] In the above setting mode, the gap between the plurality of reamers 312 of the reamer mechanism 3 and the plurality of limiting surfaces 314 actually restricts the position of the infusion needle; in other words, when the infusion needle is arranged in the gap between the plurality of reamers 312 and the plurality of limiting surfaces 314, the infusion needle has been positioned relative to the plurality of reamers 312.

[0074] In the above setting mode, the length of the side line of any limiting surface 314 can be configured in the following two ways:

[0075] First, the length of the side line of any limiting surface 314 is greater than or equal to the length of the infusion needle;

[0076] In the first setting, the infusion needle is actually accommodated between one of the limiting surfaces 314 and one of the reamers 312, or the infusion needle is actually accommodated between two adjacent limiting surfaces 314 and the corresponding two adjacent reamers 312. Through the clamping force between the reamer 312 and the limiting surface 314, the reamer 312 cuts off the infusion needle, achieving the purpose of deforming the infusion needle.

[0077] Second, the length of the side line of any one of the limiting surfaces 314 is less than the length of the infusion needle.

[0078] In the second setting, the infusion needle is actually accommodated between two adjacent limiting surfaces 314 and the corresponding two adjacent reamers 312. Through the clamping force between the reamer 312 and the limiting surface 314, the reamer 312 cuts off the infusion needle, achieving the purpose of deforming the infusion needle.

[0079] It should be understood that if the infusion needle is only restricted between one of the limiting surfaces 314 and one of the reamers 312, then the infusion needle only receives the pressure exerted by the reamer 312 on itself and the reaction force from the limiting surface 314. Before the reamer 312 actually cuts off the infusion needle, the infusion needle itself does not deform.

[0080] It should be understood that if the infusion needle is restricted between two adjacent limiting surfaces 314 and the corresponding two adjacent reamers 312, then when the infusion needle first receives the pressure exerted by the reamer 312 on itself and the reaction force from the limiting surface 314, affected by the preset angles of the two adjacent limiting surfaces 314, the infusion needle will bend with the intersection of the two adjacent limiting surfaces 314 as the center. Then, through the pressure of the reamer 312 and the reaction force of the limiting surface 314, the effect of cutting off the infusion needle is achieved.

[0081] In the known prior art, an independent fixing device is required to fix the infusion needle in order to achieve relative fixation of the infusion needle relative to the deforming mechanism.

[0082] In this embodiment, the idea of fixing the infusion needle through an independent fixing device in the prior art is changed to setting a region that can restrict the infusion needle, achieving the effect of relative fixation of the infusion needle relative to the reamer mechanism 3 (deforming mechanism). In other words, medical staff no longer need to touch the infusion needle with their hands and no longer need to operate the infusion needle to be installed at the independent fixing device in the prior art. Thus, while reducing the contact actions of medical staff's hands with the infusion needle, the occurrence of the infusion needle stabbing medical staff's hands is reduced or avoided.

[0083] Further, on the basis of all the above, a second technical problem is formed: how to arrange the infusion set between the multiple reamers 312 and the multiple limiting surfaces 314 described above.

[0084] In this embodiment, for the above-mentioned second technical problem, the technical solutions of the compression mechanism 1 and the push rod mechanism 2 are specifically adopted;

[0085] Specifically, referring to Figure 1 、 Figure 2 、 Figures 8 to 10 The compression mechanism 1 is provided with a communicating sliding channel 110 and a receiving channel 111. The infusion set can be put into the sliding channel 110, and under the action of gravity, the infusion set slides along the sliding channel 110 into the receiving channel 111;

[0086] In addition, the multiple compression components 120 of the compression mechanism 1 can limit the capacity state of the receiving channel 111; when the receiving channel 111 is in the first state, the capacity of the receiving channel 111 is at the maximum capacity, and at this time, the infusion set can be put into the receiving channel 111 through the sliding channel 110;

[0087] After the infusion set reaches the receiving channel 111, the medical staff operates the compression mechanism 1 to make the compression mechanism 1 change from the first state to the second state. Among them, when the receiving channel 111 is in the second state, the capacity of the receiving channel 111 is at the minimum capacity, and the receiving channel 111 with the minimum capacity is actually a strip-shaped channel; during this process, the infusion set is squeezed by the multiple compression components 120 of the compression mechanism 1, so that the squeezed infusion set is restricted in the strip-shaped channel. At this time, the push rod 210 of the push rod mechanism 2 can be used to push the infusion set restricted in the strip-shaped channel to move gradually or periodically, so that the infusion set in the strip-shaped channel gradually enters the crushing cavity 313 of the reamer mechanism 3, so that the infusion set is gradually or intermittently arranged between the multiple reamers 312 and the multiple limiting surfaces 314.

[0088] Therefore, in this embodiment, by setting the compression components, the actual occupied space of the infusion set is changed. In other words, the infusion set is restricted in the strip-shaped channel by the compression components. On this basis, by setting the push rod of the push rod mechanism, the infusion set restricted in the strip-shaped channel is pushed into the crushing cavity, solving the technical problem of 'how to arrange the infusion set between the multiple reamers 312 and the multiple limiting surfaces 314 described above'.

[0089] In the above setting method, the medical staff puts the whole infusion set into the sliding channel 110 of the compression mechanism 1, reducing or avoiding the phenomenon that the medical staff's hands come into contact with the infusion needle. For example, the medical staff can use pliers to clamp the infusion set and put the infusion set into the sliding channel 110;

[0090] After the infusion set slides from the sliding channel 110 into the accommodation channel 111, multiple compression components 120 of the compression mechanism 1 squeeze the infusion set, so that the space actually occupied by the infusion set is restricted within the strip-shaped channel, and the space actually occupied by the infusion set becomes smaller. Thus, when the push rod mechanism 2 pushes the infusion set, the movement path of the infusion set is restricted between the strip-shaped channel and the crushing cavity 313;

[0091] The action of the push rod 210 of the push rod mechanism 2 to push the infusion set can be a continuous and slow action or a periodic and slow action. This is because the capacity of the crushing cavity 313 of the reamer mechanism 3 is limited and cannot completely set the infusion set in the crushing cavity 313 at one time.

[0092] It should be understood that the compression mechanism 1, the push rod mechanism 2, and the reamer mechanism 3 are respectively controlled by a controller. The controller can be a PLC or a single-chip microcomputer, which is common knowledge known to those skilled in the art; in the following content, the specific structures of the compression mechanism 1, the push rod mechanism 2, and the reamer mechanism 3 are specifically provided and will not be mentioned for the time being.

[0093] It should be understood that the infusion needle of the infusion set pushed by the push rod 210 has three states relative to the crushing cavity 313:

[0094] The first state is that the contour of the infusion needle is located outside the contour of the crushing cavity 313. Thus, the multiple limiting surfaces 314 and the multiple reamers 312 cannot contact the infusion needle respectively, and at this time, the infusion needle cannot be cut off;

[0095] The second state is that a part of the contour of the infusion needle is located inside the contour of the crushing cavity 313, and the remaining contour of the infusion needle is located outside the contour of the crushing cavity 313. Thus, at least one limiting surface 314 and at least one reamer 312 can contact the infusion needle located in the crushing cavity 313. During the actual working process, the infusion needle located in the crushing cavity 313 will be bent by the pressing force of at least one reamer 312 relative to the infusion needle located outside the crushing cavity 313, and the bent infusion needle is cut off by the acting force of at least one reamer 312 and the reaction force of at least one limiting surface 314;

[0096] The third state is that the contour of the infusion needle is located inside the contour of the crushing cavity 313. Thus, the limiting surface 314 and the reamer 312 can cut off the infusion needle. For specific details, please refer to the relevant content where the edge lengths are configured as the first and the second, and will not be elaborated here.

[0097] It should be understood that, in addition to cutting the infusion needle, the reamer 312 can also cut the infusion hose; and, the infusion needle generally includes a metal needle and a plastic handle base, and the reamer 312 can cut the metal needle and the plastic handle base respectively.

[0098] Furthermore, referring to Figure 5 , in the recycling device of this embodiment, the rigid housing 311 is provided with a first opening 321 communicating with the strip-shaped channel, a second opening 322 for discharging the crushed fragments, and a third opening 323 for inserting a plurality of reamers 312;

[0099] The opening direction of the first opening 321 and the opening direction of the second opening 322 are configured to be perpendicular to each other;

[0100] The opening direction of the second opening 322 and the opening direction of the third opening 323 are configured to be opposite to each other;

[0101] The opening direction of the third opening 323 and the opening direction of the first opening 321 are configured to be perpendicular to each other.

[0102] Among them, the first opening 321 on the rigid housing 311 communicates with the strip-shaped channel of the compression mechanism 1, so that the infusion set in the strip-shaped channel can enter the crushing chamber 313 of the reamer mechanism 3 through the first opening 321;

[0103] Specifically, the cross-sectional profile of the first opening 321 and the cross-sectional profile of the strip-shaped channel are configured to be the same; or, the cross-sectional profile of the first opening 321 is configured to be larger than the cross-sectional profile of the strip-shaped channel; in these two configurations, the push rod 210 can enter the first opening 321 from the strip-shaped channel and then enter the crushing chamber 313, which enables the infusion set pushed by the push rod 210 to enter the first opening 321 from the strip-shaped channel and then enter the crushing chamber 313; in the case where the opening direction of the second opening 322 described later is configured to be the vertical direction, the opening direction of the first opening 321 here is configured to be the horizontal direction.

[0104] And, the second opening 322 is used to discharge the fragments or pieces of the crushed infusion set. Preferably, the opening direction of the second opening 322 is configured to be the vertical direction, and the opening position of the second opening 322 is located at the bottom of the rigid housing 311 in the vertical direction, so that the fragments or pieces of the infusion set can fall from the second opening 322 to the outside of the rigid housing 311 under the action of gravity.

[0105] The third opening 323 is for the insertion of the reamer 312. In other words, the moving paths of multiple reamers 312 are restricted between the third opening 323 and the crushing chamber 313. Preferably, when the opening direction of the second opening 322 is configured to be the vertical direction, the opening direction of the third opening 323 is also configured to be the vertical direction. However, the opening direction of the third opening 323 is upward, and the opening direction of the second opening 322 is downward.

[0106] Furthermore, referring to Figure 3 or Figure 4 , in the recovery device of this embodiment, the number of reamers 312 is configured to be 4;

[0107] Any one of the reamers 312 is respectively set to be cylindrical or frustum-shaped. Among them, the axis lines of all the reamers 312 are configured to be coaxially arranged, and the rotation directions of two adjacent reamers 312 are configured to be opposite to each other.

[0108] In this embodiment, the reamer 312 as a whole is preferably configured to be frustum-shaped. Its specific structure is that both ends of the reamer 312 in the axis line direction respectively have a first cone bottom and a second cone bottom. The shapes of the first cone bottom and the second cone bottom are respectively annular. Along the vertical direction, the first cone bottom is located at the bottom of the reamer 312, and the second cone bottom is located at the top of the reamer 312. The diameter of the first cone bottom is smaller than that of the second cone bottom. Along the radial direction of the reamer 312, a conical surface or a part of the conical surface is formed between the first cone bottom and the second cone bottom; multiple cutting edges are arranged on the conical surface, and the cutting direction of each cutting edge is configured to be the circumferential direction of the reamer 312.

[0109] In this embodiment, among two adjacent reamers 312, if the first reamer 312 is configured to rotate in the clockwise direction, the second reamer 312 is configured to rotate in the counterclockwise direction; correspondingly, if the cutting edge of the first reamer 312 rotating in the clockwise direction is configured to make a cutting action along the clockwise direction, the cutting edge of the second reamer 312 rotating in the counterclockwise direction is configured to make a cutting action along the counterclockwise direction. In other words, the extending direction of the cutting edge of the cutting edge of the first reamer 312 rotating in the clockwise direction is opposite to the extending direction of the cutting edge of the second reamer 312 rotating in the counterclockwise direction.

[0110] In this embodiment, the reamer 312 can also be configured to be cylindrical; however, a relatively large gap will be generated between the cylindrical reamer 312 and the limiting surface 314 of the aforementioned crushing chamber 313, which may cause the fragments of the infusion set to accumulate between the cylindrical reamer 312 and the limiting surface 314.

[0111] In this embodiment, the four reamers 312 are configured to be coaxial and arranged sequentially along the same axis line. Among them, along the vertical direction, the maximum diameter of the lower reamer 312 is less than or equal to the minimum diameter of the upper reamer 312. Thus, the four reamers 312 as a whole form a reamer 312 combination mechanism with a relatively large diameter at the upper part and a relatively small diameter at the lower part.

[0112] In this embodiment, the four reamers 312 are configured to make lifting and lowering movements along the vertical direction simultaneously, and the four reamers 312 are configured to make rotational movements in the clockwise and / or counterclockwise directions simultaneously; for the specific content of the lifting and lowering movements and the rotational movements, please refer to the following content and will not be mentioned here for the time being;

[0113] The path of the lifting and lowering movements of the four reamers 312 has an upper dead center and a lower dead center. Among them, when the four reamers 312 are at the upper dead center, the gaps between the four reamers 312 and the limiting surface 314 of the crushing chamber 313 are at the maximum gaps. At this time, the push rod 210 of the push rod mechanism 2 can push the infusion set located in the strip-shaped channel into the crushing chamber 313. From the perspective of the infusion set, a part of the infusion set is pushed into the crushing chamber 313. Then, the four reamers 312 make a descending movement simultaneously, so that during the process of the four reamers 312 moving from the upper dead center to the lower dead center, the gaps between the four reamers 312 and the limiting surface 314 of the crushing chamber 313 gradually decrease, and at least one reamer 312 contacts the infusion set located in the crushing chamber 313, thereby forming a cut on the infusion set.

[0114] In the direction from the bottom to the top along the vertical direction, the four reamers 312 are respectively defined as the first reamer 312, the second reamer 312, the third reamer 312, and the fourth reamer 312. Among them, the diameter of the first reamer 312 is the smallest, and the diameter of the fourth reamer 312 is the largest. During the process of the four reamers 312 cutting the infusion set located in the crushing chamber 313, since the fourth reamer 312 and the third reamer 312 rotate in opposite directions, a shearing action similar to that of scissors or a shearing action similar to that of pliers is formed on the infusion set in the crushing chamber 313, avoiding the negative effect of "the reamer 312 pushing the infusion set but not being able to cut the infusion set" that may occur when rotating in a single direction (hypothetically, the fourth reamer 312 and the third reamer 312 are jointly configured to rotate clockwise or counterclockwise), and improving the efficiency of cutting the infusion set. In practical applications, since the fourth reamer 312 and the third reamer 312 are located in the upper part of the vertical direction, the fourth reamer 312 and the third reamer 312 first cut the infusion set located in the crushing chamber 313. In some cases, the infusion set located in the crushing chamber 313 may reach the lower part of the vertical direction of the crushing chamber 313. At this time, the second reamer 312 and the first reamer 312 can be used to cut the infusion set located in the lower part of the vertical direction. The movement modes and the achieved technical effects of the second reamer 312 and the first reamer 312 are the same as those of the fourth reamer 312 and the third reamer 312, and will not be elaborated here.

[0115] It should be understood that the specific structure of the cutting edge can adopt various structures. For example: the cutting edge structure of scissors, the cutting edge structure of pliers, or the cutting edge structure of a crusher in an industrial crusher. Preferably, the cutting edge is configured to have a triangular pyramid shape, and one side of the triangular pyramid is used as the cutting edge. Or, the cutting edge is configured to be a strip with a cross-section approximately triangular or composed of three curves, and along the circumferential direction of the reamer 312, the cross-sectional area of one end of the cutting edge is relatively small (approximately a point), and the cross-sectional area of the other end of the cutting edge is relatively large, and one side of the cutting edge is used as the cutting edge.

[0116] It should be understood that when the cutting edge is configured in a triangular pyramid shape, or configured as a strip with a cross-section approximately triangular or a triangle composed of three curves, multiple cutting edges are respectively provided on each reamer 312, and a gap for accommodating the fragments or pieces of the infusion set is formed between adjacent cutting edges; the fragments or pieces of the infusion set located between adjacent cutting edges are separated from the four reamers 312 by the centrifugal force generated when the four reamers 312 rotate during the movement of the four reamers 312 from the lower dead center to the upper dead center. Then, the fragments or pieces of the infusion set move downward along the vertical direction under the action of gravity in the crushing chamber 313 until they are discharged from the inside of the crushing chamber 313 to the outside of the crushing chamber 313 through the aforementioned second opening 322.

[0117] Furthermore, referring to Figure 7 , in the recovery device of this embodiment, the reamer mechanism 3 further includes a gear mechanism 330 and a transmission shaft mechanism 340;

[0118] The gear mechanism 330 is configured to have four driven gears 331 for outputting kinetic energy. The four driven gears 331 are configured to be coaxially arranged, and there is a spacing between adjacent two gears. Among them, the rotation directions of adjacent two gears are configured to be opposite to each other;

[0119] The transmission shaft mechanism 340 is provided with four transmission shafts 341. The axis lines of the four transmission shafts 341 are arranged coaxially, and the four transmission shafts 341 are jointly arranged in a sleeve structure;

[0120] Any one reamer 312 is coaxially connected to one of the transmission shafts 341 respectively, and the connection position of any one reamer 312 and the transmission shaft 341 is located at the end of the transmission shaft 341.

[0121] Among them, any one driven gear 331 is coaxially connected to one of the transmission shafts 341 respectively, so that when the driven gear 331 rotates, it can drive the transmission shaft 341 connected to the driven gear 331 to rotate simultaneously; it should be understood that the connection manner between the driven gear 331 and the transmission shaft 341 can adopt the connection manners in the prior art, including welding, positioning pin connection, etc.

[0122] Among the four driven gears 331, a certain spacing is maintained between any adjacent two driven gears 331. The size of this spacing can be determined according to the connection manner between the transmission shaft 341 and the driven gear 331, as long as the connection position of the two can be exposed outside the adjacent two driven gears 331, can be observed by the human eye, and can be contacted by a simple tool (such as a welding torch);

[0123] The axis lines of the four driven gears 331 are configured to be coaxial with the axis lines of the aforementioned four reamers 312. Similarly, the axis lines of the four transmission shafts 341 are configured to be coaxial with the axis lines of the aforementioned four reamers 312. On this basis, the four driven gears 331 are respectively defined as the first driven gear, the second driven gear, the third driven gear, and the fourth driven gear from top to bottom along the vertical direction. Among them, the first driven gear has the longest distance from the four reamers 312, and the fourth driven gear has the shortest distance from the four reamers 312. Correspondingly, the transmission shaft 341 connected to the first driven gear 331 is defined as the first transmission shaft, the transmission shaft 341 connected to the second driven gear 331 is defined as the second transmission shaft, the transmission shaft 341 connected to the third driven gear 331 is defined as the third transmission shaft, and the transmission shaft 341 connected to the fourth driven gear 331 is defined as the fourth transmission shaft. The length of the first transmission shaft is greater than the length of the second transmission shaft, the length of the second transmission shaft is greater than the length of the third transmission shaft, and the length of the third transmission shaft is greater than the length of the fourth transmission shaft.

[0124] The four transmission shafts 341 are configured to be coaxial and are configured as a sleeve structure, and the adjacent two transmission shafts 341 are configured with a clearance fit. Specifically, the first transmission shaft is sleeved by the second transmission shaft, the second transmission shaft is sleeved by the third transmission shaft, and the third transmission shaft is sleeved by the fourth transmission shaft. Thus, the two ends of the first transmission shaft are respectively connected to the first driven gear and the first reamer 312, the two ends of the second transmission shaft are respectively connected to the second driven gear and the second reamer 312, the two ends of the third transmission shaft are respectively connected to the third transmission shaft and the third reamer 312, and the two ends of the fourth transmission shaft are respectively connected to the fourth transmission shaft and the fourth reamer 312.

[0125] When the first driven gear rotates, the first driven gear drives the first transmission shaft and the first reamer 312 to rotate. Similarly, the second driven gear drives the second transmission shaft and the second reamer 312 to rotate, the third driven gear drives the third transmission shaft and the third reamer 312 to rotate, and the fourth driven gear drives the fourth transmission shaft and the fourth reamer 312 to rotate.

[0126] When the rotation directions of the first driven gear and the second driven gear are opposite, the rotation directions of the first reamer 312 and the second reamer 312 are opposite. Similarly, when the rotation directions of the third driven gear and the fourth driven gear are opposite, the rotation directions of the third reamer 312 and the fourth reamer 312 are opposite.

[0127] It should be understood that the connection method between the transmission shaft 341 and the reamer 312 can adopt the connection methods in the prior art, including welding or connection by positioning pins, etc.

[0128] Further, refer to Figure 7, for the recycling device of this embodiment, the gear mechanism 330 further includes a gear frame 332 and a driving gear 333;

[0129] The gear frame 332 is provided with a first mounting section, a second mounting section, and a third mounting section. The first mounting section and the third mounting section are configured to be parallel to each other and on the same side of the second mounting section, and the first mounting section and the third mounting section are respectively fixedly connected to the second mounting section;

[0130] The 4 driven gears 331 are respectively defined as a first driven gear, a second driven gear, a third driven gear, and a fourth driven gear according to the arrangement order of the axis lines;

[0131] The first driven gear and the second driven gear are configured as a first group. On the same gear frame 332, the first driven gear is arranged on the first mounting section, the second driven gear is arranged on the third mounting section, a driving gear 333 is arranged on the second mounting section, and the first driven gear and the second driven gear are respectively meshed with the driving gear 333;

[0132] The third driven gear and the fourth driven gear are configured as a second group. On the same gear frame 332, the third driven gear is arranged on the first mounting section, the fourth driven gear is arranged on the third mounting section, a driving gear 333 is arranged on the second mounting section, and the third driven gear and the fourth driven gear are respectively meshed with the driving gear 333;

[0133] At the connection between any one of the driven gears 331 and the corresponding gear frame 332, positioning channels penetrating the driven gear 331 and the gear frame 332 are respectively provided, and one end of any one of the transmission shafts 341 is arranged in one of the positioning channels.

[0134] The aforementioned 4 driven gears 331 are divided into two groups. Correspondingly, the first driven gear and the second driven gear are arranged on the first gear frame 332, and the third driven gear and the fourth driven gear are arranged on the second gear frame 332;

[0135] On any one of the gear racks 332, a driving gear 333 is further provided respectively. The driving gears 333 on each gear rack 332 are respectively engaged with two driven gears 331. Among them, the two driven gears 331 are configured to be coaxial, and the axis lines of the driving gears 333 are respectively perpendicular to the axis lines of the two driven gears 331. Thus, when the driving gear 333 rotates, one of the driven gears 331 is driven by the driving gear 333 to rotate clockwise, and the other driven gear 331 is driven by the driving gear 333 to rotate counterclockwise. Thus, the two driven gears 331 on the same gear rack 332 respectively form rotations in opposite directions through the driving gear 333. Furthermore, the two driven gears 331 respectively drive two reamers 312 through the transmission shafts 341 to form rotations in opposite directions.

[0136] On any one of the gear racks 332, the two driven gears 331 are arranged on the first mounting section and the third mounting section of the gear rack 332, and the driving gear 333 is arranged on the second mounting section of the gear rack 332. Since the first mounting section and the third mounting section respectively form a perpendicular connection structure with the second mounting section, thus, the two driven gears 331 respectively form a positional structure with the driving gear 333 where the axis lines are perpendicular to each other. Among them, the axis lines of the two driving gears 333 are respectively perpendicular to the first mounting section and the third mounting section, and the axis lines of the driving gear 333 are respectively perpendicular to the second mounting section.

[0137] As already mentioned in the foregoing content, the number of the transmission shafts 341 is 4; on the gear rack 332 provided with the first driven gear and the second driven gear, through holes for being penetrated by at least one transmission shaft 341 are provided. Correspondingly, the first driven gear and the second driven gear should respectively be provided with through holes for being penetrated by at least one transmission shaft 341. Thus, the through holes of the driven gear 331 and the through holes of the gear rack 332 together constitute the foregoing positioning channels.

[0138] At least one transmission shaft 341 can respectively penetrate one of the through holes of the gear rack 332 and one of the through holes on the two driven gears 331, and is connected to the other driven gear 331; specifically, from the overall view of the 4 transmission shafts 341, two gear racks 332, and 4 driven gears 331, the first transmission shaft should respectively penetrate the two gear racks 332 and the remaining three driven gears 331, and then, the first transmission shaft is connected to the first driven gear; the second transmission shaft should respectively penetrate the two gear racks 332 and the remaining two driven gears 331, and then, the second transmission shaft is connected to the second driven gear; the third transmission shaft should penetrate one of the driven gears 331 and one of the gear racks 332, and then the third transmission shaft is connected to the third driven gear; the fourth transmission shaft should penetrate one of the gear racks 332, and then is connected to the fourth driven gear.

[0139] It should be understood that a rotational pair is configured between any driven gear 331 and the gear carrier 332, and the driven gear 331 and the gear carrier 332 are connected by a bearing. Thus, when the gear carrier 332 remains relatively stationary, the driven gear 331 can be in a relatively rotating state, which is common general knowledge known to those skilled in the art.

[0140] It should be understood that the connection manner between the driving gear 333 and the gear carrier 332 is the same as the connection manner between the aforementioned driven gear 331 and the gear carrier 332, and thus will not be elaborated here.

[0141] It should be understood that the driving gear 333 and the driven gear 331 are respectively configured as bevel gears, and the specific structure of the bevel gears is common general knowledge known to those skilled in the art, and thus will not be elaborated here.

[0142] It should be understood that if the driven gear 331 is connected to the transmission shaft 341 by welding, one end of the transmission shaft 341 must be inserted into the through hole of the driven gear 331, which is common general knowledge known to those skilled in the art; similarly, if the driven gear 331 is connected to the transmission shaft 341 by a positioning pin, one end of the transmission shaft 341 must be inserted into the through hole of the driven gear 331, which is common general knowledge known to those skilled in the art.

[0143] Further, referring to Figure 2 , the recovery device of this embodiment further includes a support frame 350 and a lifting mechanism 360;

[0144] The lifting mechanism 360 is provided with a fixed part 361 and a lifting part 362, and the lifting part 362 is in a liftable state relative to the fixed part 361;

[0145] The fixed part 361 is arranged on the support frame 350, and the gear carrier 332 is arranged on the lifting part 362.

[0146] Among them, the lifting mechanism 360 has an upper dead center when moving to the top in the vertical direction and a lower dead center when moving to the bottom in the vertical direction. As the lifting mechanism 360 makes a lifting motion, the gear carrier 332 connected to the lifting part 362 of the lifting mechanism 360 also makes a lifting motion. Furthermore, the driven gear 331, the driving gear 333, which are connected to the gear carrier 332, the transmission shaft 341 connected to the driven gear 331, and the reamer 312 connected to the transmission shaft 341 respectively make lifting actions.

[0147] The lifting mechanism 360 can be implemented by using various lifting mechanisms 360 in the prior art; preferably, in this embodiment, the lifting mechanism 360 is composed of a linear motor, a lifting plate, and a guide post structure, and the lifting plate among them is the aforementioned lifting part 362.

[0148] The linear motor has a motor housing, a stator, a rotor, and a motor lead screw. Among them, the stator and the rotor are respectively located inside the motor housing. The motor lead screw can be configured to penetrate the rotor, and the motor lead screw is fixedly or detachably connected to the rotor. In the connection structure between the linear motor and the lifting plate, the motor housing should be fixedly connected to the bracket for supporting the lifting mechanism 360, and one end of the motor lead screw should be connected to the lifting plate through a bearing. Thus, during the rotation driven by the stator and the rotation of the motor lead screw, the motor housing, the stator, and the rotor remain stationary relative to the bracket, while the motor lead screw and the lifting plate remain in a vertical movement state relative to the bracket. When the motor lead screw rotates relative to the motor housing, the lifting plate remains non-rotating relative to the motor housing through the bearing. In other words, the lifting plate only makes a lifting action without making a rotating action. Specifically, in the case of having a guide post structure, the guide post can limit the lifting plate from making a rotating action, which is common general knowledge known to those skilled in the art.

[0149] It should be understood that the lifting direction of the lifting mechanism 360 is the vertical direction, and the axial line directions of the 4 reamers 312 are also the vertical direction. Therefore, the axial line direction of the driving gear 333 of the gear rack 332 is the horizontal direction, and the axial line direction of the driven gear 331 is the vertical direction. On this basis, the connection method between the two gear racks 332 and the lifting part 362 can adopt a connection by a mounting plate or a mounting frame, which is common general knowledge known to those skilled in the art. The mounting plate or the mounting frame plays a role in changing the direction of connecting the gear rack 332.

[0150] Further, referring to Figure 2 or Figure 7 , the recycling device of this embodiment further includes a driving motor 370 and a transmission 380;

[0151] The transmission 380 is configured as a gear transmission 380. The transmission 380 has an input end for receiving kinetic energy and two output ends for outputting kinetic energy. The input end forms a transmission structure with the two output ends respectively;

[0152] The motor shaft of the driving motor 370 is connected to the input end;

[0153] Any one of the output ends is respectively used to connect one of the driving gears 333.

[0154] Among them, the specific structure of the gear transmission 380 is common general knowledge known to those skilled in the art and will not be elaborated here.

[0155] The drive motor 370 drives the drive gears 333 on the two gear racks 332 through the transmission 380, enabling the two drive gears 333 to rotate by means of a single drive motor 370, which results in relatively low economic costs.

[0156] The drive motor 370 and the transmission 380 are arranged on the lifting part 362 of the aforementioned lifting mechanism 360. Along with the lifting movement of the lifting part 362, the drive motor 370 and the transmission 380 also perform lifting movements. Consequently, the drive motor 370 and the transmission 380 are respectively configured to move in the same direction and at the same speed relative to the aforementioned gear rack 332, drive gear 333, driven gear 331, transmission shaft 341, and reamer 312.

[0157] It should be understood that during the lifting action of the lifting mechanism 360, the drive motor 370 can maintain the driving state of the drive gear 333 according to the instructions of the controller.

[0158] It should be understood that the connection method between the drive gear 333 and the two output ends of the transmission 380 can adopt the connection methods in the prior art, including dowel pin connection or spline connection, etc.

[0159] Furthermore, on the basis of all the above content, refer to Figures 8 to 10 , in the recycling device of this embodiment, the number of compression assemblies 120 is 4;

[0160] Each compression assembly 120 is respectively provided with a pressure plate 121 and a motor 122;

[0161] The pressure plates 121 of two of the compression assemblies 120 are configured to be parallel to each other and are respectively located at the upper and lower parts of the accommodation channel 111, and the pressure plates 121 of the remaining two compression assemblies 120 are configured to be parallel to each other and are respectively located at the left and right parts of the accommodation channel 111.

[0162] Among them, the 4 compression assemblies 120 are respectively defined as the first compression assembly, the second compression assembly, the third compression assembly, and the fourth compression assembly;

[0163] The first compression assembly is arranged at the upper part in the vertical direction of the aforementioned accommodation channel 111, and the third compression assembly is arranged at the lower part in the vertical direction of the accommodation channel 111. Moreover, the pressure plate 121 of the first compression assembly and the pressure plate 121 of the third compression assembly are configured to be parallel to the horizontal direction. The pressure plate 121 of the first compression assembly makes a lifting movement under the drive of its motor 122, and the pressure plate 121 of the third compression assembly makes a lifting movement under the drive of its motor 122;

[0164] The second compression component and the fourth compression component are respectively arranged on both sides of the accommodation channel 111, and the second compression component and the fourth compression component are both located on the same side of the aforementioned reamer mechanism 3; wherein, the pressing plates 121 of the second compression component and the pressing plates 121 of the fourth compression component are respectively parallel to the horizontal direction, and the pressing plates 121 of the second compression component are driven by their motors 122 to make telescopic movements in the horizontal direction, and, the pressing plates 121 of the fourth compression component make telescopic movements in the horizontal direction under the drive of their motors 122.

[0165] With the above arrangement, when the accommodation channel 111 is in the state of maximum volume, medical staff can put the infusion set into the accommodation channel 111, and the infusion set is supported upward along the vertical direction by the pressing plate 121 of the third compression component. At the same time, the infusion set is restricted between the first compression component, the second compression component, the third compression component and the fourth compression component; then, first drive the first compression component and the third compression component, so that the pressing plate 121 of the first compression component makes a descending movement, and the pressing plate 121 of the third compression component makes an ascending movement, so that the infusion set is squeezed by the first compression component and the third compression component along the vertical direction, so that the space occupied by the infusion set in the vertical direction is reduced; then, after the first compression component and the third compression component squeeze the infusion set, drive the second compression component and the fourth compression component, so that the pressing plate 121 of the second compression component makes a horizontal movement along the direction from the second compression component to the fourth compression component, and the pressing plate 121 of the fourth compression component makes a horizontal movement along the direction from the fourth compression component to the second compression component, so that the infusion set is squeezed by the pressing plate 121 of the second compression component and the pressing plate 121 of the fourth compression component along the horizontal direction, so that the space occupied by the infusion set in the horizontal direction is reduced;

[0166] After the first to fourth compression components respectively make the actions of squeezing the infusion set, the strip-shaped channels as described above are formed between the pressing plates 121 of the 4 compression components 120.

[0167] In this embodiment, the specific structures of the first compression component and the third compression component can be configured as the specific structures of the lifting mechanism 360 in the aforementioned reamer mechanism 3, which will not be elaborated here.

[0168] In this embodiment, refer to Figure 10, for the specific structures of the second compression component and the fourth compression component, a common motor can be used as the power source, such as a servo motor, etc., and it is provided with structures such as a gear set 123 and a ball screw 124. Among them, both ends of the screw rod of the ball screw 124 are rotatably connected to two positioning blocks through bearings, and the two positioning blocks can be fixed relative to the ground through a bracket or the like. The ball of the ball screw 124 is connected to the pressing plate 121 of the second compression component or the pressing plate 121 of the fourth compression component. During the process of the motor 122 driving the screw rod of the ball screw 124 through the gear set 123, the motor shaft of the motor 122 drives the gear set 123 to rotate, the gear set 123 drives the screw rod to rotate, the screw rod does not generate displacement relative to the ground during rotation, the screw rod drives the ball, so that the ball generates displacement relative to the ground, and the ball drives the pressing plate 121 of the second compression component or the fourth compression component, so that the pressing plate 121 makes a horizontal movement.

[0169] It should be understood that the structure of the ball screw 124 is common knowledge known to those skilled in the art and will not be elaborated here.

[0170] It should be understood that for the connection structure between the ball and the pressing plate 121, various connection methods in the prior art can be adopted, such as bolt connection, positioning pin connection, etc.

[0171] It should be understood that the motors 122 of the first compression component to the fourth compression component should be respectively arranged on the brackets, so that the motors 122 remain stationary relative to the ground.

[0172] It should be understood that on the bracket around the accommodation channel 111, there should be an opening for extruding the infusion set out of the accommodation channel 111; specifically, if the pressing plates 121 of the first compression component and the third compression component are large enough, then the bracket does not need to be provided with a surrounding plate for restricting the position of the infusion set, and only the four pressing plates 121 of the first compression component to the fourth compression component can form an opening for extruding the infusion set out of the accommodation channel 111 (as Figure 9 shown); or, if the pressing plates 121 of the first compression component and the third compression component are relatively small, then a surrounding plate can be provided on the bracket, and an opening can be opened on the surrounding plate (not shown in the figure). When the pressing plates 121 of the four compression components 120 form a strip-shaped channel, the strip-shaped channel communicates with this opening, so that the infusion set can move from the strip-shaped channel to the inside of this opening; the contour of this opening should be the same as and coincide with the contour of the strip-shaped channel, or the contour of this opening should be slightly larger than the contour of the strip-shaped channel and make the contour of the strip-shaped channel visible within the contour range of the table opening.

[0173] Further, on the basis of all the foregoing solutions, refer to Figure 2 or Figure 11, for the recycling device of this embodiment, the push rod mechanism 2 further includes a second motor 211, a ball screw mechanism 212 and a transmission gear set 213;

[0174] The transmission gear set 213 is provided with a motor gear and a lead screw gear. Among them, the second motor 211 is coaxially connected to the motor gear, and the lead screw gear is coaxially connected to the lead screw of the ball screw mechanism 212;

[0175] The ball of the ball screw mechanism 212 is connected to the push rod 210.

[0176] Among them, the push rod 210 of the foregoing push rod mechanism 2 is configured to be fixedly or detachably connected to the ball of the ball screw mechanism 212. When the second motor 211 drives the lead screw of the ball screw mechanism 212 through the transmission gear set 213, the ball makes a horizontal forward or backward movement relative to the ground, so that the ball drives the push rod 210 to make a forward or backward movement.

[0177] The structure of the ball screw mechanism 212 here is the same as that of the foregoing ball screw, which will not be elaborated here; the structure of the transmission gear set 213 here is the same as that of the foregoing gear set 123, which will not be elaborated here, and the specific structure of the second motor 211 here is common knowledge known to those skilled in the art, which will not be elaborated here.

[0178] Further, in the foregoing content, the angle of the sliding channel 110 relative to the horizontal plane is limited between 30 degrees and 60 degrees.

[0179] Specifically, on the foregoing bracket surrounding the accommodation channel 111, a guard plate 112 and a wedge block 113 are provided. The inclined surface of the wedge block 113 is used as the bottom support surface of the sliding channel 110, and the guard plate 112 is used as the side support surface of the sliding channel 110; or a guard plate 112 and a sliding plate (not shown in the figure) are provided. The sliding plate is arranged in an inclined state relative to the horizontal plane. The plate surface of the sliding plate is used as the bottom support surface of the sliding channel 110, and the guard plate 112 is used as the side support surface of the sliding channel;

[0180] The angle of the inclined surface of the wedge block 113 or the plate surface of the sliding plate relative to the horizontal plane is limited between 30 degrees and 60 degrees, which is beneficial for the infusion device to slide into the accommodation channel 111 through the inclined surface of the wedge block 113 or the plate surface of the sliding plate.

[0181] Based on all of the above, in the recycling device of this embodiment, a positioning rod 390 is further provided on the reamer mechanism 3. Among them, the positioning rod 390 is coaxially arranged with 4 reamers 312. One end of the positioning rod 390 is inserted into one of the reamers 312 or the transmission shaft 341 of this reamer 312. A detachable connection method is adopted between the positioning rod 390 and this reamer 312 or the transmission shaft 341 of this reamer 312, such as a positioning pin connection; the other end of the positioning rod 390 is configured to form a sliding pair with the aforementioned second orifice 322. Among them, when the 4 reamers 312 are at the top dead center, the positioning rod 390 is located outside the second orifice 322. When the 4 reamers 312 move from the top dead center to the bottom dead center, the positioning rod 390 can be inserted into the second orifice 322;

[0182] On the one hand, the positioning rod 390 and the second orifice 322 form a sliding pair, which can play a positioning role in the vertical direction for the 4 reamers 312 when the positioning rod 390 is inserted into the second orifice 322. On the other hand, before the positioning rod 390 is inserted into the second orifice 322, if there are fragments or pieces of the infusion set accumulated at the second orifice 322 of the crushing chamber 313, the fragments or pieces of the infusion set at the second orifice 322 can be extruded out of the second orifice 322 through the positioning rod 390, so that the fragments or pieces of the infusion set are separated from the outside of the crushing chamber 313.

[0183] In addition to the foregoing, it should be understood that in other embodiments, the reamer mechanism 3 can also be configured with more or fewer reamers 312, driven gears 331, and driving gears 333, which is easy to think of by those skilled in the art after seeing the technical solution of this embodiment.

[0184] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
