The vibrating plate feeding device usually includes a feeding track or a feeding tray, and a vibration mechanism that drives the feeding track or the feeding tray to vibrate. The material can vibrate and move along the feeding track or the feeding tray under the self-vibration of the feeding track or the feeding tray. By selecting the specific structure and layout of the feeding track or the feeding tray, the disorderly arranged materials can be gradually arranged automatically, orderly, and directionally during the vibration movement of the materials, and accurately transported to the subsequent process.

[0043] Figure 1 A perspective view of a material delivery device 100 for delivering medical material according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 Schematic cross-sectional view of the cylindrical housing 103 of the material conveying device 100. For simplicity, Figure 2 The lower part of the middle cylindrical shell is simplified by section lines. The present invention is not intended to limit the specific internal structure of the components arranged in the lower part of the cylindrical shell 103. Those skilled in the art can arrange a suitable structure as needed.

[0044] like Figure 1 As shown, the material conveying device 100 includes a feed track 101, an electrostatic elimination mechanism 102, a cylindrical shell 103 and a vibration mechanism (not shown in the figure). The feed track 101 is arranged to extend from the inside of the cylindrical shell 103 and is arranged around the upper edge of the cylindrical shell 103. The vibration mechanism is arranged inside the cylindrical shell 103 to drive at least the proximal end of the feed track 101 (i.e., the end located in the cylindrical shell 103) to vibrate, so that the medical material on the feed track 101 can move along the feed track 101 toward its distal end (i.e., the end away from the cylindrical shell 103) under the action of the vibration, so as to output the medical material from the distal end of the feed track 101.

[0045] It should be noted that, in this article, "proximal end" refers to the end of the conveyor track or its section that receives medical materials, "upstream" refers to the side adjacent to the proximal end of the conveyor track or its section; and "distal end" refers to the end of the conveyor track or its section that outputs medical materials, and "downstream" refers to the side adjacent to the distal end of the conveyor track or its section.

[0046] Continue to refer to Figure 1The feed track 101 includes a first track segment 111, a second track segment 112 adjacent to or connected to a distal end 162 of the first track segment 111, and a third track segment 113 adjacent to or connected to a proximal end 161 of the first track segment 111. Figure 1 and Figure 2 As shown, the third track segment 113 is at least partially arranged inside the cylindrical housing 103, and generally has a spiral shape that gradually rises from its proximal end to its distal end. When the third track segment 113 is driven by the vibration mechanism to vibrate, the medical material in the cylindrical housing 103 is driven to rise along the spiral third track segment 113 through its own vibration.

[0047] like Figure 2 As shown, the proximal end 163 of the third track segment 113 is located in the cylindrical shell 103, and the distal end 164 thereof is adjacent to or connected to the proximal end 161 of the first track segment 111, and the height of the distal end 164 is substantially equal to or higher than the proximal end 161 of the first track segment 111, so that the medical material delivered from the distal end 164 of the third track 113 can easily enter the first track segment 111.

[0048] like Figure 1 As shown, the first track segment 111 includes 7 first sub-tracks 171. Although the first sub-tracks in the embodiment shown in the figure are 7, the first track segment 111 may also include other numbers of sub-tracks. For example, in some embodiments, the first track segment 111 may include 2, 3, 4, 5, 6, 8, 9, 10 or other numbers of sub-tracks. Figure 1 As shown, different sub-tracks are separated by the protrusion 172, so that the medical material entering the first track segment 111 from the distal end 164 of the third track segment 113 can be introduced into different first sub-tracks 171 by the protrusion 172. Subsequently, driven by the vibration mechanism, the multiple sub-tracks 171 of the first track segment 111 drive the material to move toward the distal end 162 of the first track segment 111 along each sub-track 171 through vibration. The distal end 162 of the first track segment 111 is adjacent to or connected to the proximal end 165 of the second track segment 112, and the height of the distal end 162 is substantially equal to or higher than the proximal end 165 of the first track segment 112, so that the medical material sent out from the distal end 162 of the first track segment 111 can smoothly enter the second track segment 112.

[0049] Figure 3 Shows Figure 1 The diagram is a partially enlarged perspective view of the adjacent portion of the first track segment 111 and the second track segment 112 of the material conveying track of the material conveying device 100 . Figure 4 Shows Figure 1 The illustrated diagram is a partial enlarged top view of the adjacent portion of the first track segment 111 and the second track segment 112 of the material conveying track of the material conveying device 100 .

[0050] like Figure 3 As shown, in the cross section, the bottom surface of the first track segment 111 is inclined at a certain angle α relative to the horizontal plane, so that one side of the bottom surface of each first sub-track 171 ( Figure 3 The right side of the Figure 3 In some embodiments, the angle α is set to 2 to 30°, preferably 5 to 15°. By setting the bottom surface of the first track segment 111 (first sub-track 171) in this way, the medical material moving along each first sub-track 171 toward the distal end 162 of the first track segment 111 during the vibration movement gradually approaches the protrusion 172 on the left side of the first sub-track 172 under the action of gravity and moves forward in sequence.

[0051] Continue to refer to Figure 1 The second track segment 112 includes multiple second sub-tracks 181, and each second sub-track 181 is arranged in alignment with the multiple sub-tracks 171 of the first track segment 111, wherein each second sub-track 181 is adjacent to or connected to the distal end of the corresponding first sub-track 171 at the proximal end 165 of the second track segment 112, and the height of the proximal end of the second sub-track 181 is approximately equal to or lower than the distal end of the corresponding first sub-track 171.

[0052] like Figure 1 As shown, the width of each second sub-track 181 is smaller than the width of the corresponding first sub-track 171. In some embodiments, the width of the second sub-track 181 can be set to be 1.1 to 1.9 times the outer diameter of the medical material (i.e., the maximum radial dimension of the medical material, for example, the outer diameter of a cylindrical medical material, and the longest diagonal length of a quadrangular prism medical material). Figure 3 As shown, the proximal end of the second sub-track 181 is arranged to be adjacent to the protrusion 172 on the lower side of the first sub-track 171, so that the medical material moving sequentially along the protrusion 172 on the first sub-track 171 can smoothly enter the corresponding second sub-track 181. Although the second sub-tracks 181 shown in the figure are 7, the second track segment 112 can also include other numbers of second sub-tracks 181 corresponding to the number of first sub-tracks 171.

[0053] Through the construction and arrangement of the third track segment 113, the first track segment 111, and the second track segment 112 of the feed track 101 described above, the medical material put into the barrel housing 103 can move along the feed track 101, and gradually separate during the movement and output from the second track segment 112 of the feed track to enter the subsequent device or processing process. In some embodiments, the surface of one or more of the third track segment 113, the first track segment 111, and the second track segment 112 can be processed, such as polishing, coating, etc., to reduce the resistance of the medical material moving thereon.

[0054] Further, if Figure 4 As shown, a plurality of suction holes 114 spaced apart along the conveying direction of the material may be provided in the region adjacent to the second track segment 112 in the first track segment 111. Correspondingly, the material conveying device 100 further includes a suction mechanism (not shown in the figure) for generating a suction airflow, the suction mechanism being in fluid communication with at least one of the plurality of suction holes 114, thereby generating a suction airflow at the suction hole 114.

[0055] By setting the suction mechanism and the suction hole 114, when the medical material is transported and passes through Figure 3 and 4 At the suction hole 114 shown, due to the suction airflow generated by the multiple suction holes 114, the particles, dust or particles attached to the surface of the medical material can be sucked into the suction holes 114, thereby effectively reducing the amount of particles, dust or particles adsorbed on the surface of the medical material.

[0056] It should be noted that although the suction hole 114 is arranged in the area of ​​the first track segment 111 relatively adjacent to the second track segment 112 as shown in the figure, in some embodiments, the suction hole 114 can also be set in other areas of the conveyor track 101, such as the third track segment 113, the area of ​​the first track segment 111 relatively adjacent to the third track segment 113, the second track segment 112, etc.

[0057] like Figure 3 The plurality of suction holes 114 shown are arranged along the conveying direction of the medical material ( Figure 3The plurality of suction holes 114 are arranged at intervals (in the direction indicated by the dashed arrow in the middle), and are arranged near the relatively lower side of the bottom surface of the first sub-track 171 in the lateral direction, but other feasible arrangements of the plurality of suction holes 114 may also be adopted. For example, in some embodiments, the plurality of suction holes 114 may be arranged on the bottom surface of the feeding track 101 along a generally S-shaped curve. In some embodiments, the plurality of suction holes 114 may be arranged at uneven intervals along the conveying direction of the medical material, for example, in the area on the first sub-track 171 that is relatively adjacent to the second sub-track 181, the distance between two adjacent suction holes 114 is shorter than the distance between two adjacent suction holes 114 in the upstream area thereof.

[0058] The shape and size of the suction hole 114 can be appropriately set according to actual needs, so that under the action of the suction mechanism, a suction airflow can be formed to effectively suck particles, dust or particles on the surface of the medical material, but the suction airflow will not significantly increase the transmission resistance of the medical material and hinder the forward movement of the medical material. Figure 3 and 4 In the illustrated embodiment, the suction hole 114 is configured as a circular hole with a diameter of 0.5 mm to 2.5 mm. Those skilled in the art should understand that the shape of the suction hole 114 is not limited to a circle, and may also have other shapes, such as a rectangle, a diamond, a racetrack, an ellipse, a trapezoid, etc.

[0059] When the medical material passes through the suction hole, due to the suction effect, the surface of the medical material is easy to stick to the suction hole, resulting in temporary blocking of the suction hole 114, which is not conducive to the effective removal of particles, dust or particles. In order to avoid the situation where the medical material sticks to the suction hole as much as possible, in some embodiments, at least one recessed portion can be provided on the bottom surface of the feed track 101, and at least one suction hole 114 is provided in each recessed portion. Due to the presence of the recessed portion, the medical material can be transported across the top of the recessed portion, and it is not easy to stick to the suction hole 114, thereby effectively improving the suction efficiency of particles, dust or particles on the surface of the material. In some embodiments, a plurality of suction holes 114 can be arranged in the recessed portion to achieve a better suction effect. Viewed from directly above the feed track, the shape of the recessed portion can be at least one of the following shapes: rectangular, circular, elliptical and runway-shaped. In order to facilitate the suction of particles on the medical material, in some embodiments, a rounded portion can be provided between the recessed portion and the surface of other parts of the feed track 101.

[0060] The suction mechanism of the medical material conveying device 100 can be any mechanism that can be fluidically connected to the suction hole 114 and generate a suction airflow at the suction hole 114, for example, a centrifugal fan, an axial flow fan, and a diagonal flow (mixed flow) fan. In some embodiments, the suction mechanism can also be a volumetric fan, such as a vane fan, a screw fan, a Roots fan, a piston fan, and a diaphragm fan. The suction mechanism can also be arranged at any position that can be fluidically connected to the suction hole 114. In some embodiments, the suction mechanism can be arranged in the cylindrical housing 103. In other embodiments, the suction mechanism can be arranged outside the cylindrical housing 103 to avoid being affected by the vibration mechanism.

[0061] Continue to refer to Figure 1 The material conveying device 100 further includes a static elimination mechanism 102, which is configured to blow airflow with positive and negative ions to the conveying track 101, so that the positive and negative ions can neutralize the charge carried by the medical material, effectively reducing the electrostatic adsorption of the medical material to particles, dust or particles. Figure 1 As shown, the ion outlet 121 (indicated by the dotted line in the figure) of the static elimination mechanism 102 is arranged to be above the conveying track 101 and generally toward the second track segment 112 and the third track segment 113, but in some embodiments, the ion outlet 121 can also be arranged in other directions.

[0062] In some embodiments, the ion air outlet 121 can be arranged to at least partially face the suction hole 114, so that it can cooperate with the suction mechanism to effectively remove the particles, dust or particles electrostatically adsorbed on the surface of the material. In some embodiments, the static elimination mechanism 102 can also be configured to enable the ion air outlet 121 to move relative to the feed track 101 to adjust the distance of the ion air outlet 121 relative to the feed track 101 and / or the orientation relative to the feed track 101 to achieve a better material static removal effect.

[0063] During the movement of medical materials on the feeding channel 100, static electricity and particles, dust or particles may be generated due to friction. Before the medical materials are put into the material conveying device 100, their surface may also adsorb particles, dust or particles. These particles will be adsorbed on the material under the action of static electricity. The particles, dust or particles adsorbed on the medical materials may enter the final product formed by subsequent assembly and processing along with the medical materials, which may cause quality problems in the final product and even lead to recall events. Therefore, measures need to be taken to prevent and reduce the retention of particles, dust or particles on the medical materials. The material conveying device 100 of the present application can more efficiently remove particles, dust or particles adsorbed on the surface of the medical materials through the static elimination effect of the static elimination mechanism 102, combined with the suction effect of the suction airflow generated by the suction mechanism at the suction port 114, thereby effectively avoiding quality problems of the final product caused by particles, dust or particles.

[0064] Figure 5 Shows Figure 1 The control system schematic block diagram of the medical material delivery device 100 is shown in FIG. Figure 5 As shown, the medical material conveying device 100 includes a controller that is communicatively connected to the static elimination mechanism 102. In some embodiments, the controller of the medical material conveying device 100 is configured to control the ion wind outlet 121 to move toward the conveyor track 101 and / or increase the air outlet speed of the ion wind outlet 121 when receiving a signal indicating that the medical material is stuck on the conveyor track 101, so as to improve the static removal effect of the medical material and avoid the adhesion effect caused by the electrostatic force between the surface of the medical material and the vibrating disk. In some embodiments, the ion wind outlet 121 of the static elimination mechanism 102 can also be provided with an adjustable fan blade structure, so that the positive and negative ion airflows blown out by it can cover a wider range on the conveyor track 101.

[0065] The static elimination mechanism 102 can be any feasible structure that can generate positive and negative ion airflow. In some embodiments, the static elimination mechanism 102 can be a DC ion blower, an AC ion blower, or a pulse ion blower. In some embodiments, the static elimination mechanism 102 mainly includes a corona discharger for generating positive and negative ions, a high-voltage power supply for supplying power to the corona discharger, and an air supply system. Although the static elimination mechanism 102 is arranged directly above the feed track 101 as shown in the figure, in some embodiments, the static elimination mechanism 102 can also be arranged in other directions of the feed track 101, such as to the side or above the side.

[0066] In the present application, the vibration mechanism that drives the feed track 101 to vibrate to drive the movement of the material can adopt any available mechanism that can drive the feed track 101 to move. In some embodiments, the vibration mechanism can be an electromagnetic vibration drive mechanism, which drives the feed track 101 or the transmission component connected to the feed track 101 to vibrate through the pulse electromagnet arranged at least partially below or to the side of the feed track 101, through the change of the magnitude of its magnetic attraction. In other embodiments, the vibration mechanism can be a mechanical vibration mechanism, for example, the feed track 101 or the transmission component connected thereto is driven to vibrate by a motor. In some embodiments, the vibration mechanism is a piezoelectric ceramic vibration mechanism, and its piezoelectric ceramic sheet is engaged with the feed track 101 or the transmission component connected to the feed track 101 to transmit the movement generated by the piezoelectric ceramic sheet to the feed track 101.

[0067] In some embodiments, the controller of the medical material conveying device 100 is configured to control the vibration mechanism to vibrate the conveyor track 101 with a higher vibration frequency and / or amplitude when receiving a signal indicating that the medical material is stuck at the conveyor track 101, so that the medical material on the conveyor track 101 can restore its orderly motion state through vibrations of higher frequency and / or larger amplitude. In some embodiments, the controller of the medical material conveying device 100 can also be configured to control the vibration mechanism to intermittently drive at least a portion of the conveyor track 101 to vibrate. In some embodiments, the vibration mechanism can drive the conveyor track 101 to vibrate for a first time period each time, and a second time period is separated between two adjacent vibrations, and the second time period is 1 to 5 times the first time period. In some embodiments, during the second time period, the static elimination mechanism 102 and the suction mechanism stop working at the same time. In other embodiments, during the second time period, at least one of the static elimination mechanism and the suction mechanism does not stop working.

[0068] The signal received by the controller indicating that the medical material is stuck at the feed track 101 can be provided by a sensor. The sensor can be any type of sensor that can detect whether there is medical material at at least one position of the feed track. In some embodiments, the sensor can be a proximity sensor arranged near the feed track 101, such as a reflective, retro-reflective or through-beam photoelectric proximity sensor. In other embodiments, the above signal can also be provided by the operator of the medical material conveying device 100. Specifically, a button or other input device for confirming that a material is stuck at the feed track can be provided on the operation panel of the medical material conveying device 100. When the operator finds that a material is stuck at the feed track 101, a signal indicating that the medical material is stuck at the feed track 101 can be sent to the controller through the button or other input device.

[0069] Figure 6FIG. 2 shows a perspective view of a medical material delivery device 600 according to another embodiment of the present application, wherein the static elimination mechanism of the medical material delivery device is removed to better show the structure of other parts thereof. Figures 1 to 4 The medical material delivery device 100 shown is substantially the same and will not be described again herein.

[0070] like Figure 6 As shown, the medical material conveying device 600 further includes a plurality of discharge pipes 604, the proximal ends of which are correspondingly connected to the distal ends of the plurality of second sub-tracks 681 of the second conveying track section 612 of the conveying track 601, so as to receive the outputted materials from the corresponding second sub-tracks 681. In some embodiments, the medical material is generally cylindrical, conical or truncated cone-shaped, and the inner diameter of the discharge pipe is 1.1 to 1.5 times the maximum outer diameter of the medical material. Although not shown in the figure, in some embodiments, the medical material conveying device 600 further includes a material pipe vibrating mechanism 605 for vibrating the discharge pipe 604.

[0071] like Figure 5 As shown, the material pipe vibration mechanism is also in communication with the controller of the medical material conveying device. In some embodiments, the controller of the medical material conveying device can be configured to drive the material pipe vibration mechanism 605 to vibrate the discharge pipe 604 when receiving a signal indicating that the medical material is stuck at the discharge pipe 604. Other structures of the material conveying device 600 are similar to Figures 1 to 4 The material conveying device 100 shown is substantially the same and will not be described in detail herein.

[0072] The signal received by the controller indicating that the medical material is stuck at the discharge pipe 604 can also be provided by a sensor. The sensor can be any type of sensor that can detect whether there is medical material at at least one position of the discharge pipe 604. In some embodiments, the sensor that provides the above signal can be a proximity sensor arranged near the discharge pipe 604, such as a reflective, retroreflective or through-beam photoelectric proximity sensor. In some embodiments, the sensor that provides the above signal can be a proximity sensor arranged near the proximal end and the distal end of the discharge pipe 604, respectively. In other embodiments, the above signal can also be provided by the operator of the medical material conveying device 600. Specifically, a button or other input device for confirming that the discharge pipe is stuck can be set on the operation panel of the medical material conveying device 600. When the operator finds that the discharge pipe 604 is stuck, the button or other input device can be used to send a signal indicating that the medical material is stuck at the discharge pipe 604 to the controller.

[0073] Figure 7FIG. 1 is a perspective view of a medical material conveying device 700 according to another embodiment of the present application, wherein the static elimination mechanism and part of the side wall of the material conveying track of the medical material conveying device are removed to better show the structure of other parts. Figures 1 to 4 The medical material delivery device 100 shown is substantially the same and will not be described again herein.

[0074] like Figure 7 As shown, the plurality of second sub-tracks 781 of the medical material conveying device 700 are arranged at intervals, and the interval between two adjacent second sub-tracks 781 is greater than the outer diameter of the conveyed medical material. The medical material conveying device 700 is provided with a return track 706 at least below the second track segment 712. Medical materials that fail to move in an orderly manner along the second sub-tracks 781 can fall into the return track 706 from the intervals between the second sub-tracks 781.

[0075] Continue to refer to Figure 7 , a return port 731 is provided at the distal end of the return track 706 adjacent to the cylindrical shell 703 of the medical material conveying device 700. The return track 706 gradually descends along the conveying direction of the medical material to the return port 731 downstream, and is connected to the third track segment through the return port 731. In this way, the medical material falling into the return track 706 from the second sub-track 781 and its gap can return to the third track segment through the return port 731, and can rise again along the spiral third track segment to the first track segment under the vibration of the third track segment to be re-conveyed and oriented. In some embodiments, the return port 731 can also be provided upstream of the return track 706, and correspondingly, the return track 706 gradually rises from the return port 731 along the conveying direction of the medical material, so that the medical material falling on the return track 706 moves to the return port 731 under the action of gravity and returns to the third track segment through the return port 731.

[0076] The medical material conveying device of the present application can be used to convey medical materials of any shape. In some embodiments, the medical material conveying device is configured to convey long materials (such as tubular materials, columnar materials, or strip materials) with uniform dimensions along the length direction. In other embodiments, the material conveying device can also be used to convey long materials with non-uniform dimensions along the length direction, such as non-uniform long materials with a first end dimension greater than a second end dimension.

[0077] Figure 8 FIG. 8 is a perspective view of a medical material delivery device 800 according to another embodiment of the present application, wherein the static elimination mechanism of the medical material delivery device is removed to better show the structure of other parts. Figures 1 to 4The medical material conveying device 100 shown is substantially the same, the main difference being that a limiting mechanism 890 is arranged at the junction of the first sub-track 871 and the second track segment 881 of the medical material conveying device 800, for adjusting the movement posture of non-uniform elongated materials (for example, the first end size of the medical material is larger than the second end size) along the conveying track 801, so that the medical material leaves the conveying track 101 with its relatively smaller second end in front.

[0078] Fig. 9 A partial enlarged perspective view of the junction of the first track segment 811 and the second track segment 812 of the medical material conveying device 800 is shown. Fig.10 A partial enlarged perspective view is shown of the medical material conveying device 800 after the limiting mechanism at the junction of the first track segment 811 and the second track segment 812 is removed. Fig.11 A schematic top view of a limit stopper of the limit mechanism of the medical material conveying device 800 is shown.

[0079] like Fig.10 As shown, the proximal end of the second sub-track 881 of the second track segment 812 is constructed to have a substantially arc-shaped transition track segment 882. The relatively high proximal end of the transition track segment 882 is adjacent to the distal end of the first sub-track 871, and the distal end of the transition track segment 882 is lower than the first sub-track 871, so that the medical material output from the distal end of the first sub-track 871 can smoothly enter the second sub-track 881 along the transition track segment 882.

[0080] like Fig. 9 As shown, the limiting mechanism 890 includes a limiting baffle 891, which is arranged along the conveying direction of the material to shield the far end of the first sub-track 871 and at least a portion of the transition track section 882 of the second sub-track 881, and the limiting baffle 891 is provided with a limiting groove 892. Fig.11 As shown, the limiting groove 892 includes a guide section 893 and a release section 894, wherein the guide section 893 extends along the medical material conveying direction at least to a position flush with the distal end of the first sub-track 871 or even beyond the distal end of the first sub-track 871, and the release section 894 is located above the transition track section 882 of the second sub-track 881.

[0081] The groove width of the guide section 893 is larger than the outer diameter of the second end of the non-uniform elongated medical material and smaller than the outer diameter of the first end thereof. Among the non-uniform elongated medical materials transported on the first sub-track 871, only the relatively small medical materials with the second end facing downward can smoothly enter the guide section 893, while medical materials in other postures cannot enter the guide section 893. These medical materials that cannot enter the guide section 893 will be squeezed out of the first sub-track 871 by the subsequent medical materials, and then fall into the return track below the second track section 812. Under the action of gravity, the relatively small second end of the medical materials that successfully enter the guide section 893 faces downward, so that the medical materials are supported in a substantially vertical posture in the guide section 893 of the limit baffle 891.

[0082] The slot width of the release section 894 is set to be larger than the outer diameter of the relatively larger first end of the medical material. When the medical material enters the release section 894 in a substantially vertical posture, the limit stopper 891 can no longer support the medical material, so that the medical material falls onto the transition track section 882 of the second sub-track section 881 under the action of gravity, and continues to be transported in the second sub-track 881 with the second end facing forward.

[0083] like Fig.10 As shown, in some embodiments, the limiting mechanism 890 also includes an upper baffle 895, which is arranged above the transition track segment 882. The upper baffle 895 and the transition track segment 882 jointly define the conveying path of the medical material, so that the medical material falling into the transition track segment 882 moves smoothly toward the distal end of the second sub-track 882 without changing its posture.

[0084] Although not shown in the figure, the medical material conveying device 800 may further include a blowing mechanism, which has a first blowing port arranged to blow airflow toward the limit baffle 891 transverse to the conveying direction of the medical material. Medical materials that have not entered the limit groove 892 of the limit baffle 891 due to incorrect movement posture can be blown off in time to avoid material jams. In other embodiments, the blowing mechanism also includes a second blowing port that blows airflow toward the second sub-track 881 transverse to the conveying direction of the medical material, which is used to blow off medical materials that are stuck at the second sub-track 881. These blown-off medical materials can fall into the return track below the second sub-track 881, and be reintroduced into the third track segment through the return port of the medical material conveying device.

[0085] The medical material conveying device of the present application can be configured to convey medical materials, such as a port tube, an end cap or an injection plug of a medical infusion system, etc. Due to the use of various components and mechanisms as described above, the medical materials can be more efficiently conveyed, and the contamination of the medical materials caused by surface adsorption of particles, dust or particles can be effectively avoided.
