[0002] The sterile silicone negative pressure drainage ball (i.e. medical drainage ball) is mainly used for liquid drainage in the medical field, such as postoperative wound drainage, closed chest drainage, etc. The main function of the medical drainage ball is to drain the liquid, blood, exudate, etc. in the wound or organ through the negative pressure effect, so as to avoid the occurrence of effusion and infection.

[0003] In the prior art, the medical drainage ball includes a drainage ball bag, a drainage tube, a one-way valve, and a connecting ball cap. Among them, the one-way valve is one of the most critical structures for maintaining negative pressure. The Chinese patent document with publication number CN219963556U discloses a closed and pollution-proof negative pressure drainage ball.

[0004] Among them, the one-way valve in the medical drainage ball is also called a duckbill valve, which is made of silicone. One end of the duckbill valve is duckbill-shaped, and an opening is formed at the end. In the prior art, the opening is mostly processed by a semi-automatic equipment or laser cutting. The semi-automatic equipment needs manual intervention for positioning, and the silicone is prone to deformation, resulting in a high scrap rate, and the opening quality cannot be detected in real time.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] An opening device for a medical one-way valve, used to open the one-way valve in a medical drainage ball. See also... Figure 1 As shown, the present invention is used to simultaneously open multiple arrays of one-way valves 51 integrally formed on the valve assembly 5.

[0023] In this embodiment, the valve assembly 5 is integrally molded from silicone through injection molding. Multiple one-way valves 51 are arranged in a rectangular array in the central region of the valve assembly 5, and an outer peripheral edge 52 protruding outwards surrounds the central region. Each one-way valve 51 has a cylindrical portion at the bottom and a duckbill-shaped valve port at the top. After injection molding, the straight valve port at the top of the valve port is closed; therefore, it is necessary to open the one-way valve 51.

[0024] Please see Figure 2 and Figure 3 As shown, the opening device includes a robot 1, and a storage mechanism 2, an opening mechanism 3, a vision inspection mechanism 4, and a control device distributed around the robot 1. The storage mechanism 2, the opening mechanism 3, and the vision inspection mechanism 4 are all located within the travel range of the robot 1. The robot 1 is used to transport the valve transfer component, which consists of a carrier 21 and a valve assembly 5. Specifically, the robot 1 is used to transport the valve assembly 5, carried by the carrier 21, between the storage mechanism 2, the opening mechanism 3, and the vision inspection mechanism 4.

[0025] Please see Figure 2As shown, the carrier 21 of the valve transfer component is U-shaped, with a hollowed-out central area. The carrier 21 consists of an upper frame 211 and a lower frame 212 that are detachably connected to each other. Both the upper frame 211 and the lower frame 212 are frames with a hollowed-out central area. In this embodiment, the upper frame 211 and the lower frame 212 are interlocked. In the valve transfer component, the outer periphery 52 of the valve assembly 5 is clamped and fixed by the upper frame 211 and the lower frame 212, and the one-way valve 51 of the valve assembly 5 is placed in the hollowed-out area of ​​the carrier 21.

[0026] In this embodiment, a carrier 21 can simultaneously clamp and fix two valve assemblies 5 to form a valve transfer component. The two valve assemblies 5 are symmetrically distributed at the front and rear ends of the carrier 21, and the carrier 21 clamps the outer periphery 52 on three sides of each valve assembly 5. Specifically, the front, left, and right outer periphery of one valve assembly 5 is clamped, and the rear, left, and right outer periphery of the other valve assembly 5 is clamped.

[0027] For further details, please refer to Figure 2 As shown, the upper frame 211 and the lower frame 212 are engaged by connecting protrusions and connecting grooves. Both the left and right sides of the outer walls of the upper frame 211 and the lower frame 212 are provided with transporting protrusions 213 that cooperate with the gripper of the robot 1. The transporting protrusions 213 are symmetrically arranged on the upper frame 211 and the lower frame 212, respectively. A first pin hole 214 is vertically formed on the carrier 21. A second pin hole 53 is correspondingly formed on the outer periphery 52 of the valve assembly 5. The carrier 21 and the valve assembly 5 are fixed together by the first pin hole 214, the second pin hole 53, and a fixing pin.

[0028] Preferably, the upper frame 211 and the lower frame 212 are frame bodies with the same structure, both having a connecting protrusion at the top and a corresponding connecting groove at the bottom. The connecting groove at the bottom of the upper frame 211 engages with the connecting protrusion at the top of the lower frame 212, and the connecting groove at the bottom of the lower frame 212 is adapted to cooperate with the positioning block 338 on the opening mechanism 3.

[0029] The storage mechanism 2 includes at least three racks 22. The racks 22 are used to place valve transfer components. In this embodiment, there are three racks 22: a processing rack, a qualified product rack, and a defective product rack. The processing rack is used to place valve transfer components that have not been opened. The qualified product rack is used to place valve transfer components with qualified openings, and the defective product rack is used to place valve transfer components with unqualified openings. The robot 1 can transport the valve transfer components in the processing rack to the opening mechanism 3. After the opening mechanism 3 processes and opens the one-way valve 51 in the valve transfer component, the robot 1 can transport the opened valve transfer component to the vision inspection mechanism 4. The vision inspection mechanism 4 is used to detect whether the opening of the one-way valve 51 in the valve transfer component is qualified. The control device is adapted to control the robot 1 to transport the corresponding valve transfer component to the corresponding rack 22 according to the detection result of the vision inspection mechanism 4; that is, the robot 1 transports the valve transfer components with qualified openings to the qualified product rack and the valve transfer components with unqualified openings to the defective product rack.

[0030] In this embodiment, the inner sidewalls on both sides of the material rack 22 are provided with horizontal pull-out grooves or horizontal support plates for supporting the valve transfer component, so that the valve transfer component can be horizontally arranged in the material rack 22. When the inner sidewall of the material rack 22 is provided with horizontal support plates, the horizontal support plates are arranged at intervals in the vertical direction.

[0031] In this embodiment, the robot 1 has a telescopic arm with a gripper at the end to flexibly move the valve transfer component to a designated location.

[0032] In this embodiment, the visual inspection mechanism 4 is a visual image inspection device that detects the position and size of the opening on the one-way valve 51 by acquiring images of the valve. The visual image inspection device is existing technology and will not be described in detail.

[0033] Please see Figure 4 and Figure 5 As shown, the opening mechanism 3 includes a lower frame 31 and an upper frame 35 arranged opposite to each other. The top of the lower frame 31 has a receiving station and an opening station. The receiving station and the opening station are spaced apart in the front-to-back direction. The receiving station is close to the vision inspection mechanism 4 and the material rack 22, while the opening station is away from the vision inspection mechanism 4 and the material rack 22. A loading platform 32 is provided on the lower frame 31, which moves back and forth between the receiving station and the opening station. The loading platform 32 is slidably mounted on the top of the lower frame 31 via a drive module 36. The drive module 36 is a linear drive module used to drive the loading platform 32 to move in the front-to-back direction, so that the loading platform 32 moves to the receiving station or the opening station. A tool assembly 33 is provided on the top of the loading platform 32. The upper frame 35 is located above the opening station, and a liftable pressure plate 34 is provided on the upper frame 35.

[0034] In this embodiment, the pressure plate 34 is vertically and flexibly mounted on the upper frame 35 via a lifting module 38. The lifting module 38 includes, but is not limited to, cylinders, lifting motors, and hydraulic cylinders. In this embodiment, the pressure plate 34 is a polyurethane board.

[0035] When the loading platform 32 is located at the handover station, the robot 1 is adapted to place the valve transfer component that has not been opened on the tool assembly 33, or to take the valve transfer component that has been opened from the tool assembly 33 and send it to the vision inspection mechanism 4.

[0036] When the unopened valve transfer component is placed on the tool assembly 33 (specifically, each one-way valve 51 is fitted onto the cutting edge of each tool 331) and transported to the opening station by the loading table 32, the valve transfer component is located between the tool assembly 33 and the pressure plate 34. The control device drives the pressure plate 34 to descend through the drive module 36, and the pressure plate 34 presses the unopened one-way valve 51 on the tool assembly 33, thereby causing the tool 331 located in the corresponding one-way valve 51 to cut open the valve port from the inside of the one-way valve 51 at the top of the one-way valve 51.

[0037] Furthermore, to ensure effective cooperation between the tool assembly 33 and the pressure plate 34, a vision positioning device 37 is provided on the upper frame 35. The vision positioning device 37 faces the opening position and is used to determine whether the loading platform 32 carrying the unopened valve transfer component has reached the opening position. When the vision positioning device 37 detects that the loading platform 32 carrying the unopened valve transfer component has reached the opening position, the control device controls the lifting module 38 to drive the pressure plate 34 to press down and cooperate with the tool assembly 33 to open the one-way valve 51.

[0038] In this embodiment, the visual positioning device 37 is placed above the pressure plate 34, and the pressure plate 34 has an avoidance notch to prevent the pressure plate 34 from blocking the image acquisition lens of the visual positioning device 37.

[0039] Furthermore, to ensure that the loading platform 32 moves accurately to the handover station, the lower frame 31 is equipped with a positioning detection device at the handover station to sense whether the loading platform 32 is positioned at the handover station. The loading platform 32 moves from the opening station to the handover station. When the positioning detection device senses the loading platform 32, the drive module 36 stops driving the loading platform 32, so that the loading platform 32 stops accurately at the handover station.

[0040] Both the visual positioning device 37 and the positioning detection device are existing technologies. Therefore, they will not be described in detail.

[0041] Please see Figures 6-8As shown, the tool assembly 33 includes a tool holder and a tool 331. The tool holder includes a top plate 332, a bottom plate 333, and support columns 334 disposed between the two. The bottom plate 333 is disposed on the loading platform 32. Specifically, the bottom plate 333 is fixed in a mounting groove at the top of the loading platform 32, and the bottom of the mounting groove has a clearance groove for avoiding the lower end of the tool 331. The top plate 332 is positioned above the loading platform 32, and the support columns 334 are distributed at the four corners of the bottom plate 333. The top of the top plate 332 is provided with a positioning block 338 for positioning the carrier 21. Specifically, the connecting groove at the bottom of the lower frame 212 is adapted to be positioned on the positioning block 338.

[0042] In this embodiment, the upper end of the cutter 331 is the cutting edge. The cutting edge slides vertically through the top plate 332 and extends upwards above the top plate 332. In this embodiment, the shape of the cutting edge is the same as the inner cavity shape of the one-way valve 51, and the top of the cutting edge has a straight cutting edge. The cutting edge of the cutting edge is formed by the intersection of two inclined planes.

[0043] Each one-way valve 51 in the valve transfer component is adapted to be sleeved on each cutting edge. The lower end of the cutting tool 331 is a limiting end. The limiting end slides vertically through the base plate 333 and extends downward to below the base plate 333. A spring 335 is sleeved on the cutting tool 331. The spring 335 is placed between the top plate 332 and the base plate 333, with its upper end abutting against the cutting tool 331 and its lower end abutting against the base plate 333.

[0044] Furthermore, the cutting tool 331 is also provided with a limiting protrusion 336. The limiting protrusion 336 is located between the top plate 332 and the bottom plate 333. The upper end of the spring 335 rests on the lower edge of the limiting protrusion 336, while the upper edge of the limiting protrusion 336 is limited to the lower surface of the top plate 332. That is, the top plate 332 is located above the limiting protrusion 336, which limits the upward movement of the cutting tool 331 in the vertical direction.

[0045] When the pressure plate 34 presses down, the cutting edge engages with the pressure plate 34 to open the upper end of the one-way valve 51. During this opening, the pressure plate 34 presses down, and the cutting tool 331, under pressure, moves slightly downwards with elasticity. After the opening is complete, the pressure plate 34 rises to reset, separating itself from the cutting edge. At this point, the cutting tool 331 moves upwards to reset under the action of the spring 335.

[0046] In this embodiment, on the same tool holder, there are several tools 331 arranged in a matrix to accommodate the various one-way valves 51 on the valve assembly 5.

[0047] Furthermore, to prevent the cutting tools 331 from rotating, a limiting shaft 337 is fixedly installed between the limiting ends of the cutting tools 331 distributed in the same row on the same tool holder. The limiting ends of the cutting tools 331 have radial through holes, which are located below the pressure plate 34. The limiting shaft 337 extends in the left-right direction, passing through and fixing itself to the corresponding radial through holes, so that the cutting edges of the cutting tools 331 distributed in the same row are flush, and the cutting edge directions of the cutting edges of the cutting tools 331 distributed in the same row are consistent. In addition, the limiting shaft 337 also effectively prevents the cutting tools 331 from rotating around their own axis, thus playing an anti-rotation role.

[0048] Additionally, as shown in Figure 7, a loading sensor 339 is also provided at the top of the top plate 332 next to the cutter 331 to monitor whether the valve transfer component is placed on the cutter 331. At the handover station, when the loading sensor 339 detects that the unopened valve transfer component has been placed on the cutter 331 by the robot 1, the loading sensor 339 transmits a signal to the control device, which can then control the drive module 36 to drive the loading platform 32 to move towards the opening station.

[0049] In this embodiment, multiple tool assemblies 33 are fixed on the loading platform 32. These tool assemblies 33 are arranged in a matrix. In this embodiment, there are eight tool assemblies 33, arranged in two rows and four columns.

[0050] In this embodiment, the control device is electrically connected to the robot 1, the drive module 36, the vision positioning device 37, the lifting module 38, the position detection device, the loading sensor 339, and the vision inspection mechanism 4.

[0051] The working principle of this invention is as follows: The control device first controls the drive module 36 to move the loading platform 32 to the handover station; When the control device determines that the loading platform 32 is located at the handover station and there is no valve transfer component on the tool assembly 33, the control device controls the robot 1 to place the valve transfer component in the storage rack to be processed on the tool assembly 33 so that each one-way valve 51 is fitted on the corresponding blade tip. When the loading sensor 339 detects a valve transfer component on the cutting tool 331, the control device controls the drive module 36 to move the loading table 32 to the opening position; After the visual positioning device 37 detects that the loading platform 32 has moved to the opening position, the control device controls the lifting module 38 to drive the pressure plate 34 to press down. The blade end cooperates with the pressure plate 34 to open the upper end of the one-way valve 51. After the opening is completed, the control device controls the lifting module 38 to drive the pressure plate 34 to rise and reset, so that the pressure plate 34 is separated from the blade end. At this time, the cutter 331 moves upward and resets under the action of the spring 335. Then, the control device controls the drive module 36 to move the loading platform 32 to the handover station, and then controls the robot 1 to transport the valve transfer component on the tool assembly 33 to the vision inspection mechanism 4; the vision inspection mechanism 4 detects whether the one-way valve 51 after opening in the valve transfer component is qualified, and the control device controls the robot 1 to transport the corresponding valve transfer component to the qualified product storage rack or the defective product storage rack according to the detection result of the vision inspection mechanism 4.

[0052] This invention, through the cooperation of a robot, storage mechanism, opening mechanism, visual inspection mechanism, and control device, eliminates the need for manual operation. It effectively opens medical one-way valves while reducing the risk of contamination, thus improving work efficiency and quality control. The effective opening of the medical one-way valve is achieved through the cooperation of a cutting tool assembly, carrier, and pressure plate.

[0053] The above is a detailed description of one embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent protection scope of the present invention.
