[0035] The utility model embodiment provides a sharp object extraction mechanism, see Figures 1 to 3 The sharp weapon extraction mechanism comprises a fixed shaft 1, a roller 2, a claw structure 3 and a clamping claw 4; wherein:
[0036] The outer periphery of the fixed shaft 1 forms a cylindrical cam structure 11;
[0037] The drum 2 rotates around the fixed axis 1;
[0038] The claw structure 3 is connected to the roller 2 in an axially sliding manner along the fixed shaft 1; the claw structure 3 is connected to the cylindrical cam structure 11, and the claw structure 3 is used to place the target infusion bottle bag 6 and clamp the neck of the target infusion bottle bag 6; during the rotation of the roller 2, the claw structure 3 is used to move along the axial direction of the fixed shaft 1 under the drive of the cylindrical cam structure 11;
[0039] The clamping jaws 4 are disposed on the roller 2 , and are used for clamping the target infusion tube 7 of the target infusion bottle bag 6 .
[0040] In this embodiment, the cylindrical cam structure 11 refers to a component with a curved groove on the cylindrical surface or a curved profile on the cylindrical end surface, and the claw structure 3 can cooperate with the above-mentioned curved groove or curved profile through a corresponding follower; for example, when the cylindrical cam structure 11 refers to a component with a curved groove on the cylindrical surface, the claw structure 3 can be rolled in the curved groove through a wheel body structure; when the cylindrical cam structure 11 refers to a component with a curved profile on the cylindrical end surface, the claw structure 3 can be slidably fitted on the curved profile through a push rod structure, and the claw structure 3 can also be rolled on the curved profile through a wheel body structure.
[0041] The fixed shaft 1 can be inserted into the roller 2, and the target infusion bottle bag 6 can be placed on the outer peripheral surface of the roller 2. Since the cylindrical cam structure 11 can convert the rotational motion around the axis direction into the linear motion along the axis direction, when the roller 2 rotates around the fixed shaft 1 under the drive of the motor and other driving components, the claw structure 3 can rotate relative to the cylindrical cam structure 11 with the rotation of the roller 2, so that the claw structure 3 will be driven by the cylindrical cam structure 11 to move along the axial direction of the fixed shaft 1, and then drive the target infusion bottle bag 6 clamped on the claw structure 3 to move axially relative to the roller 2; and when the target infusion tube 7 of the target infusion bottle bag 6 is clamped by the clamping claw 4 and cannot move axially, when the claw structure 3 moves away from the clamping claw 4 in the axial direction under the drive of the cylindrical cam structure 11, it will cause the infusion bottle bag body and the target infusion tube 7 to be pulled relative to each other, so that the target infusion tube 7, puncture device and other sharp objects can be pulled out from the rubber plug 61 of the target infusion bottle bag 6. It can be understood that the clamp 4 can be set to be movable, and the opening and closing movement of the clamp 4 can be realized with the help of a corresponding driving assembly or mechanical structure, so that the clamp 4 can automatically clamp the target infusion tube 7 when the drum 2 rotates to the position where the target infusion tube 7 and the sharp object need to be pulled out; and after completing the above-mentioned pulling out operation, the clamp 4 can be automatically loosened, so that the pulled out sharp object falls into the sharp object collection container 10 below, so as to complete the sorting and collection of the sharp objects.
[0042] Based on the above arrangement, in actual application, after the infusion is completed, the medical staff can insert the pulled-out infusion needle back into the rubber plug 61 of the target infusion bottle bag 6. At this time, the target infusion tube 7 is bent into a U-shape; Figure 3As shown, taking the fixed axis 1 being arranged horizontally as an example, the medical staff can place the target infusion bottle bag 6 horizontally on the outer peripheral surface of the drum 2, and clamp the neck of the target infusion bottle bag 6 with the claw structure 3 to fix the target infusion bottle bag 6 on the drum 2, and place the target infusion tube 7 at the clamping claw 4; a cutting assembly 8 for cutting the target infusion tube 7 is arranged at a preset position on the left side of the drum 2; when the drum 2 starts to rotate counterclockwise, the target infusion bottle bag 6 rotates with the drum 2, and when the target infusion bottle bag 6 rotates to the cutting assembly 8, the clamping claw 4 clamps the target infusion tube 7, and at this time, the cutting assembly 8 can cut the target infusion tube 7 near the rubber plug 61 with the assistance of the clamping claw 4. ; When the main part of the target infusion tube 7 is cut off and falls into the infusion tube collection container 9 below, the claw structure 3 is also driven by the cylindrical cam structure 11 to move axially in the direction away from the clamping jaw 4, thereby pulling the target infusion bottle bag 6, so that the remaining part of the target infusion tube 7 connected with sharp tools such as puncture tools and infusion needles can be pulled out from the rubber stopper 61 of the target infusion bottle bag 6 under the pulling force, thereby realizing the separation of the sharp tools from the infusion bottle bag body; then the clamping jaw 4 can be opened, and the remaining part of the target infusion tube 7 connected with sharp tools such as puncture tools and infusion needles will fall into the sharp tool collection container 10 below, thereby completing the sorting and collection of the target infusion tube 7, infusion needles and puncture tools.
[0043] It can be seen that the sharp weapon extraction mechanism provided in this embodiment clamps the neck of the target infusion bottle bag 6 through the claw structure 3 slidably connected to the roller 2, and clamps the target infusion tube 7 of the target infusion bottle bag 6 through the clamping claw 4 arranged on the roller 2; by utilizing the cooperation between the claw structure 3 and the cylindrical cam structure 11, during the rotation of the claw structure 3 with the roller 2, the cylindrical cam structure 11 can drive the claw structure 3 to move axially, thereby driving the target infusion bottle bag 6 clamped on the claw structure 3 axially close to or axially away from the clamping claw 4; when the target infusion bottle bag 6 axially moves away from the clamping claw 4, it will cause relative pulling between the infusion bottle bag body and the target infusion tube 7, so that sharp weapons such as puncture devices and infusion needles can be pulled out from the rubber stopper 61 of the target infusion bottle bag 6. Compared with the traditional method of separating sharp objects, the separation method based on the sharp object removal mechanism realizes the removal and separation of sharp objects while avoiding excessive contact between medical staff and infusion needles, puncture devices and other sharp objects. It is more convenient to operate, has a higher sorting and collection efficiency, reduces the risk of needlestick injuries for medical staff, and has a higher safety factor.
[0044] Optionally, refer to Figures 1 to 3 A guide groove 111 is provided on the outer peripheral surface of the cylindrical cam structure 11, and the guide groove 111 extends along the first path. The first path has a first sub-path and a second sub-path. The first sub-path is the axial direction of the fixed shaft 1, and the second sub-path is the circumferential direction of the cylindrical cam structure 11; the claw structure 3 is slidably fitted in the guide groove 111 through the driven component 5.
[0045] Specifically, since the guide groove 111 extends along the axial direction of the fixed shaft 1 and the circumferential direction of the cylindrical cam structure 11 at the same time, the driven component 5 can be driven by the guide groove 111 to move along the axial direction of the fixed shaft 1 during the rotation of the claw structure 3 relative to the cylindrical cam structure 11, thereby driving the target infusion bottle bag 6 clamped on the claw structure 3 to move axially relative to the roller 2. The driven component 5 can adopt a slider structure or a wheel structure, and the groove wall of the guide groove 111 can form a limiting effect on both sides of the driven component 5, so that the driven structure can always be connected with the cylindrical cam structure 11, and the driven structure is prevented from being separated from the cylindrical cam structure 11.
[0046] Optionally, refer to Figures 1 to 3 The driven component 5 includes a roller 51 , and the roller 51 is rollingly fitted in the guide groove 111 .
[0047] Based on the rolling cooperation between the roller 51 and the guide groove 111, the friction force can be reduced, the smoothness of the axial movement of the claw structure 3 can be ensured, and the excessive wear of the device can be avoided. Figure 2 As shown, a support 52 may be provided on the claw structure 3 , and the roller 51 may be connected to the support 52 .
[0048] Optionally, refer to Figures 1 to 3 The roller 2 is arranged around the cylindrical cam structure 11, and the roller 2 is provided with an avoidance through hole (not shown in the figure), and the driven component 5 is penetrated in the avoidance through hole.
[0049] In this embodiment, the drum 2 is a hollow structure, the fixed shaft 1 is inserted into the drum 2, and the cylindrical cam structure 11 is arranged in the internal space of the drum 2, so that the space can be reasonably utilized, the volume occupied by the sharp object extraction mechanism is reduced, and the structure of the sharp object extraction mechanism is more compact. By providing an avoidance through hole on the drum 2, the claw structure 3 on the outer peripheral surface of the drum 2 can be connected to the cylindrical cam structure 11 through the driven component 5 inserted into the avoidance through hole; specifically, taking the driven component 5 as an example of the roller 51 in the previous embodiment, as shown in FIG. Figure 2 As shown, the roller 51 is connected to the claw structure 3 via a support 52, and the support 52 can be arranged through the avoidance through hole.
[0050] Optionally, refer to Figures 1 to 3 The outer periphery of the roller 2 forms a placement plane (not shown in the figure); the claw structure 3 includes a claw body 31 and a support plate 32, the claw body 31 is connected to the support plate 32, the claw body 31 is used to clamp the neck of the target infusion bottle bag 6, the support plate 32 is slidably matched on the placement plane, and the support plate 32 is used to place the target infusion bottle bag 6.
[0051] In this embodiment, the claw body 31 can be arranged on one side of the support plate 32 close to the clamping claw 4; by setting the support plate 32, on the one hand, the contact area between the claw structure 3 and the roller 2 can be increased by utilizing the cooperation between the support plate 32 and the placement plane, thereby improving the stability of the claw structure 3 during axial sliding; on the other hand, the relatively flat surface of the support plate 32 can be utilized to place the target infusion bottle bag 6, thereby improving the placement stability of the target infusion bottle bag 6.
[0052] Optionally, refer to Figures 1 to 3 A guide portion (not shown in the figure) is provided on the placement plane, and a matching portion (not shown in the figure) is provided on the support plate 32, which is slidably matched on the guide portion along the axial direction of the fixed shaft 1; one of the guide portion and the matching portion is a guide rail portion, and the other of the guide portion and the matching portion is a slider portion.
[0053] In this embodiment, a guiding effect can be formed by the sliding fit between the guide portion and the matching portion, thereby ensuring that the support plate 32 always accurately moves axially relative to the drum 2, thereby improving the stability of the subsequent sharp tool extraction operation.
[0054] Optionally, refer to Figures 1 to 3 , the sharp weapon extraction mechanism includes a driving device (not shown in the figure), which is used to drive the roller 2 to rotate;
[0055] The drum 2 is provided with a first detection through hole (not shown in the figure), and the support plate 32 is provided with a second detection through hole 321, and the second detection through hole 321 is opposite to the first detection through hole; an in-position sensor device (not shown in the figure) is arranged inside the drum 2, and the in-position sensor device is electrically connected to the driving device;
[0056] The in-place sensing device is used to output an open signal to the driving device when the presence of the target infusion bottle bag 6 on the pallet 32 is detected through the first detection through hole and the second detection through hole 321; and / or, the in-place sensing device is used to output a close signal to the driving device when the presence of the target infusion bottle bag 6 on the pallet 32 is detected through the first detection through hole and the second detection through hole 321.
[0057] In this embodiment, in order to avoid the in-position sensor device rotating together with the drum 2 and causing the cable to be entangled, the in-position sensor device can be connected to the fixed structure inside the drum 2 by direct or indirect connection. For example, the in-position sensor device can be installed on the fixed shaft 1, which is not limited here. The in-place sensing device includes but is not limited to a proximity switch, a distance sensor and a photoelectric sensor, which is used to detect whether the target infusion bottle bag 6 has been placed on the support plate 32. Taking the in-place sensing device as an example, the light beam emitted by the in-place sensing device can pass through the first detection through hole and the second detection through hole 321 in sequence and then be emitted from the placement plane of the support plate 32. When the light beam is blocked, it can be determined that the target infusion bottle bag 6 has been placed on the support plate 32 and covers the second detection through hole 321. At this time, an opening signal can be output to the drive device to trigger the drive device to start or put the drive device in a startable state; and when the light beam emitted by the in-place sensing device is not blocked, it can be determined that the target infusion bottle bag 6 is not placed on the support plate 32. At this time, a closing signal should be output to the drive device to put the drive device in a non-startable state to avoid the drive device starting automatically when the corresponding device is not deployed, causing equipment damage and personal injury. When the in-place sensing device uses other types of sensors, its detection process can also be inferred in the same way, which will not be repeated here.
[0058] It is understandable that the electrical connection between the in-place sensor device and the drive device is not limited to a direct wired connection, as long as the electrical signal transmission and signal interaction between the in-place sensor device and the drive device can be achieved. In an exemplary embodiment, the in-place sensor device can be electrically connected to the drive device through a corresponding control module, for example, the in-place sensor device can be electrically connected to the drive device through an MCU microcontroller unit; in this way, the control module can control the in-place sensor device to perform a detection operation by sending a detection signal, and the control module can output a corresponding on signal or off signal to the drive device after receiving the detection data sent by the in-place sensor device, so as to trigger the drive device to perform a corresponding operation.
[0059] This embodiment provides an in-place sensor device, which can automatically trigger the drive device to start working when the target infusion bottle bag 6 is placed, and can prevent the drive device from operating on its own when the target infusion bottle bag 6 has not been placed, thereby improving the reliability and safety of the sharp tool extraction mechanism and enhancing the automation and intelligence of the equipment.
[0060] Optionally, refer to Figures 1 to 3 The claw structure 3 has two bayonet holes 311, and the bayonet holes 311 are used to clamp the neck of the target infusion bottle bag 6.
[0061] Illustratively, when the claw structure 3 includes two bayonet holes 311 , each bayonet hole 311 can be used to clamp and fix the neck of the target infusion bottle bag 6 , so that it is compatible with single-head infusion bottle bags and double-head infusion bottle bags, thereby improving the applicability of the sharp tool extraction mechanism.
[0062] Optionally, refer to Figures 1 to 3 The sharp weapon extraction mechanism includes at least two claw structures 3 and at least two clamping jaws 4; the at least two claw structures 3 and at least two clamping jaws 4 are evenly distributed on the roller 2 along the circumference of the roller 2.
[0063] When the number of the claw structures 3 and the number of the clamping jaws 4 are two or more, the target infusion bottle bags 6 fixed on the drum 2 can also be set to two or more, and the placement position of the target infusion bottle bag 6 corresponds to the position of the claw structure 3 and the clamping jaw 4 one by one; in this way, during the rotation of the drum 2, each target infusion bottle bag 6 can be driven to the preset position in turn, and the clamping jaw 4 clamps the target infusion tube 7 of the corresponding target infusion bottle bag 6, and the puncture device, infusion needle and other sharp tools of each target infusion bottle bag 6 are pulled out in turn in the above-mentioned embodiment, so that the separation operation of the sharp tools on multiple target infusion bottle bags 6 can be completed at one time, and the continuous sorting and collection of the target infusion bottle bags 6 is realized.
[0064] Correspondingly, the present utility model embodiment also provides an infusion waste sorting device, please refer to Figures 1 to 3 The infusion waste sorting device includes the sharp object extraction mechanism in any of the above embodiments.
[0065] In this embodiment, based on the improvement of the sharp tool extraction mechanism, in actual application, after the infusion is completed, the medical staff can insert the extracted infusion needle back into the rubber plug 61 of the target infusion bottle bag 6. At this time, the target infusion tube 7 is bent into a U-shape; Figure 3As shown, taking the fixed axis 1 being arranged horizontally as an example, the medical staff can place the target infusion bottle bag 6 horizontally on the outer peripheral surface of the drum 2, and clamp the neck of the target infusion bottle bag 6 with the claw structure 3 to fix the target infusion bottle bag 6 on the drum 2, and place the target infusion tube 7 at the clamping claw 4; a cutting assembly 8 for cutting the target infusion tube 7 is arranged at a preset position on the left side of the drum 2; when the drum 2 starts to rotate counterclockwise, the target infusion bottle bag 6 rotates with the drum 2, and when the target infusion bottle bag 6 rotates to the cutting assembly 8, the clamping claw 4 clamps the target infusion tube 7, and at this time, the cutting assembly 8 can cut the target infusion tube 7 near the rubber plug 61 with the assistance of the clamping claw 4. ; When the main part of the target infusion tube 7 is cut off and falls into the infusion tube collection container 9 below, the claw structure 3 is also driven by the cylindrical cam structure 11 to move axially in the direction away from the clamping jaw 4, thereby pulling the target infusion bottle bag 6, so that the remaining part of the target infusion tube 7 connected with sharp tools such as puncture tools and infusion needles can be pulled out from the rubber stopper 61 of the target infusion bottle bag 6 under the pulling force, thereby realizing the separation of the sharp tools from the infusion bottle bag body; then the clamping jaw 4 can be opened, and the remaining part of the target infusion tube 7 connected with sharp tools such as puncture tools and infusion needles will fall into the sharp tool collection container 10 below, thereby completing the sorting and collection of the target infusion tube 7, infusion needles and puncture tools.
