Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment assembly, and in particular relates to an assembly mechanism of a pump tube component and a catheter. Background Art

[0002] Medical pump tube assembly is a commonly used infusion device in the medical industry, such as Fig.11 As shown, the medical pump tube assembly includes a pump tube and a pump connecting pipe installed at both ends of the pump tube. The pump connecting pipe generally includes a large interface, a small interface and a side interface. The large interface is connected to the pump tube, and the side interfaces at both ends are respectively connected to the catheter. In order to ensure the processing and assembly efficiency and avoid bacterial contamination, the assembly of the pump connecting pipe and the catheter needs to be completed by automated equipment.

[0003] The Chinese utility model patent with application number "201620766238X" discloses an assembly device for a medical pump pipe and a catheter, including a material picking mechanism for clamping the pump pipe and a tube clamping mechanism for clamping the catheter to be assembled. The material picking mechanism includes material picking clamping fingers for clamping the pump pipe, a clamping finger driving source for driving the material picking clamping fingers to open and close, and a lifting cylinder for driving the material picking clamping fingers to rise and fall; the tube clamping mechanism includes a tube clamping assembly for clamping the catheter to be assembled and a tube clamping driving source for driving the tube clamping assembly to open and close. The material picking clamping fingers clamp the pump pipe to be assembled and the catheter on the tube clamping assembly for plug-in assembly.

[0004] Since the pump connector is a connecting tube with three channels, the above-mentioned assembly device of the medical pump connecting tube and the catheter needs to clamp and adjust the pump connecting tube multiple times before the pump connecting tube and the catheter can be assembled, and the assembly efficiency is low. In addition, the loading and unloading of the pump connecting tube requires additional control of the material taking mechanism, the assembly process and equipment structure are complicated, and the assembly efficiency of the pump tube assembly is low.

[0005] The Chinese invention patent with application number "2022115815705" discloses an automated assembly device for medical pump pipes and catheters, including a base and a pump pipe, a loading tray is installed on the top of the base, a loading trough for stacking pump pipes is arranged inside the loading tray, and a stop mechanism is arranged at the bottom of the loading trough; it also includes a material transport ring sleeved on the outside of the loading tray, a mounting frame is arranged on the top of the base, and two sets of plug-in mechanisms are arranged on the side of the mounting frame close to the material transport ring. Through the cooperation of the material transport ring and the clamping hole, the material transport ring can drive the pump pipe to move, and then through the cooperation of the clamping hole and the feeding protrusion, it can be clamped while feeding. However, in the above-mentioned automated assembly device for medical pump pipes and catheters, the disc-shaped loading and unloading structure can only operate one pump pipe at a time, and the overall assembly efficiency is still not high enough.

[0006] In addition, both of the above solutions are to take out the pump connecting pipe separately and assemble it with the catheter. However, in the actual production and processing process, in order to facilitate the transportation and assembly of the pump tube assembly, the pump connecting pipe is often installed on both ends of the pump tube first, and then the catheter is assembled to both ends of the pump connecting pipe. However, the current existing technology has not been able to provide an efficient automated equipment for installing the catheter on the side interface of the pump tube assembly. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention aims to solve the problems of low assembly efficiency and inability to cooperate with a pump tube assembly to assemble a catheter in the prior art.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A pump tube assembly and a catheter assembly device, comprising a feeding mechanism for clamping the catheter and a pump tube positioning mechanism, characterized in that the feeding mechanism comprises a gantry frame erected above the pump tube positioning mechanism, a horizontal slide rail is arranged on the crossbeam of the gantry frame, and a lifting and lowering material taking installation assembly is slidably installed on the gantry frame;

[0010] The pump pipe positioning mechanism comprises a base frame and a shell, a base plate is fixed on the base frame, a base plate slide rail is provided on the base plate, a positioning part support plate is slidably connected to the base plate slide rail, a plurality of groups of rotating clamping finger assemblies, a front bearing seat and a rear bearing seat are horizontally and equidistantly arranged on the positioning part support plate, and a positioning part cylinder for driving the positioning part support plate and the rotating clamping finger assembly to slide synchronously is fixedly connected to the bottom surface of the base plate;

[0011] The rotating finger assembly includes fingers for clamping the pump pipe, a finger driving source for controlling the opening and closing of the fingers, a rotating fixed block fixedly connected to the rear end of the finger driving source, a rotating shaft fixedly connected to the rear end of the rotating fixed block, and a rotating motor fixedly connected to the bottom surface of the positioning part support plate. The rotating shaft passes through the front bearing seat and the rear bearing seat respectively provided with bearings. Synchronous wheels are correspondingly provided on the rotating shaft and the output shaft of the rotating motor, and the two synchronous wheels are connected by a synchronous belt transmission.

[0012] The pump pipe positioning mechanism of this scheme can slide forward and backward. When the pump pipe assembly is delivered to the right place, the positioning cylinder pushes the pump pipe positioning mechanism to move toward the pump pipe delivery line. The clamping finger driving source drives the clamping finger to clamp the pump pipe and fix the side interface of the pump pipe vertically upward. After the material taking installation assembly clamps the catheter and moves it above the clamping finger, it drives the catheter to descend and plug it into the side interface. Because the catheter is relatively long, during the process of clamping and moving the catheter by the material taking installation assembly, the catheter will be dragged on the outer shell of the pump pipe positioning mechanism. At this time, the rotating motor drives the rotating clamping finger assembly to rotate and drive the pump pipe assembly to rotate, pulling the catheter to hang in the same direction on the side of the pump pipe delivery line, so that the pump pipe assembly and the catheter are placed in order to avoid mutual interference. Then the clamping finger opens, and the pump pipe positioning mechanism slides back and recovers to avoid the pump pipe positioning mechanism from touching the pump pipe assembly. The whole assembly process is simple and smooth. There is no need to clamp the catheter or pump pipe assembly multiple times. Only one clamping and assembly action is required to complete the assembly of multiple sets of catheters and pump pipe assemblies, further improving the assembly efficiency.

[0013] The assembly device of the pump tube assembly and the catheter also includes a material shifting mechanism, which includes a column, a push plate and a push plate driving source for driving the push plate to slide horizontally. A locking block is provided on the column, and a horizontally arranged material shifting pad is fixedly connected to the locking block, and the bottom surface of the material shifting pad is fixedly connected to the push plate driving source; the push plate is horizontally arranged above the outer shell, and includes a connecting part, a horizontal part and a downwardly inclined part, one end of the connecting part is fixedly connected to the push plate driving source, and the side of the connecting part is fixedly connected to the horizontal part, the horizontal part and the inclined part are integrally formed, and the inclined part is "L" shaped, and one part is close to the upper surface of the outer shell and does not touch it, and the other part is close to the side of the outer shell and does not touch it.

[0014] The column is located on one side of the pump pipe positioning mechanism, and the "L"-shaped push plate inclined portion tends to wrap around the upper surface and side of the shell. The push plate driving source can drive the push plate to move backward, move the catheter to prevent the catheter from getting stuck, and the inclined portion located on the side can also push the catheter hanging on the side of the pump pipe positioning mechanism close to the column back to the upper surface of the shell during the pushing process, so as to avoid the catheter getting stuck, pulled and damaged during transportation.

[0015] In the above-mentioned assembly device of the pump tube assembly and the catheter, the clamping finger includes a clamp, a transition section and a clamping finger connecting section. The clamp is provided with a first recess for accommodating a large interface of a pump tube, a through groove portion for clamping a side interface of the pump tube, a second recess for accommodating a small interface of the pump tube, and a clamp limit block for limiting the position of the pump tube. The outer end of the through groove portion is provided with a reduced diameter tube guide hole.

[0016] Furthermore, the slide rail is also slidably connected with a detection positioning mechanism, which includes a camera detection component with a lens facing downward and a sliding fixing frame for fixing the camera detection component. The camera detection component and the chuck are positioned accordingly, and through detection observation holes are provided on the left and right sides of the chuck.

[0017] A transition section is provided between the connection section of the clamp head and the clamp finger to increase the length of the clamp finger, which is convenient for clamping and can also avoid mutual interference between the positioning mechanism components of the catheter and the pump pipe. The first recess, the second recess and the through groove portion provided inside the clamp head of the clamp finger form a cavity corresponding to the shape of the pump pipe for accommodating and positioning the pump pipe. The clamp head limit block can press against the end of the small interface of the pump pipe when the rotating clamp finger assembly extends forward to clamp the pump pipe, so that the pump pipe can accurately fall into the cavity formed by the first recess, the second recess and the through groove portion, and when the catheter is plugged in, the insertion guide hole at the upper end of the through groove portion can guide the insertion action to achieve precise assembly; when the catheter is plugged in, the rotating clamp finger assembly drives the catheter to rotate 90°, at which time the camera detection assembly slides to the top of the clamp head, and performs video detection through the through detection observation hole to determine whether the catheter and the pump pipe are plugged in place.

[0018] In the above-mentioned assembly device of the pump tube assembly and the catheter, the material picking installation assembly includes a material picking translation plate, a sliding block compatible with the slide rail is fixedly connected to the material picking translation plate, a material picking lifting drive source is fixedly connected to the other side of the material picking translation plate, the material picking lifting drive source is fixedly connected to a horizontally arranged material picking lifting plate and can drive the material picking lifting plate to rise and fall, a flip support plate is fixedly connected to the left and right ends of the material picking lifting plate respectively, a flip plate is flipably connected between the two flip support plates, a flip assembly for driving the flip plate to flip is fixedly connected to the outer side of the flip support plate, and a plurality of catheter clamping finger assemblies are fixedly connected to the flip plate at equal distances.

[0019] In this solution, after the pump tube assembly is positioned, the side interface of the pump tube is in a vertically upward state, and the catheter needs to be stood up for plugging. The catheter is generally placed horizontally on the platform. When the material taking installation assembly clamps the catheter, the interface of the catheter is also in a horizontal state. In order to facilitate plugging, the flip plate is rotated by the flip assembly and the catheter clamping finger assembly on the flip plate and the catheter are synchronously flipped 90°, so that the interface of the catheter is in a vertical state. The catheter clamping finger assembly drives the catheter to descend to complete the plugging. There is no need to perform more operations on the pump tube assembly or the catheter, which further simplifies the assembly process and improves assembly efficiency.

[0020] Furthermore, the flip assembly includes a horizontally arranged flip driving source and a flip fixing block fixedly connected to the outer side of the flip support plate, the flip driving source is fixedly connected to the outer side of the flip fixing block and the rotating shaft passes through the flip fixing block, the flip support plate and the flip plate are fixedly connected, a square flip limiting groove is opened on the flip fixing block, a flip connecting block is fixedly connected to the rotating shaft of the flip driving source and the flip connecting block is arranged in the flip limiting groove, the flip connecting block and the flip limiting groove are arranged concentrically, the outer peripheral surface of the flip connecting block is fixedly connected to the limiting block, and when the limiting block rotates, it conflicts with the side of the flip limiting groove to limit the flip angle to 90°

[0021] Through the cooperation of the limit block and the flip limit slot, the flip angle is precisely controlled at 90°. In the initial state, the lower end face of the limit block conflicts with the lower side face of the flip limit slot. When the flip assembly is flipped to 90°, the upper end face of the limit block conflicts with the other side face of the flip limit slot. The flip angle is precisely controlled at 90° through a simple mechanical structure.

[0022] Furthermore, the catheter finger clamp assembly includes a catheter finger and a catheter finger clamp driving source for driving the catheter finger to open and close, the catheter finger clamp includes a finger clamp connecting portion and a finger clamping head portion, the finger clamping head portion is located on the side of the finger clamp connecting portion, when the catheter finger clamp assembly is closed, the clamped catheter is located on the side of the catheter finger clamp driving source and is parallel to the catheter finger clamp driving source.

[0023] In common catheter finger clamp assemblies, the catheter finger clamp driving source is vertically arranged, the finger clamping head is located at the bottom of the finger clamping connection part, and the installation direction of the catheter finger clamp is consistent with the rod head direction of the catheter finger clamp driving source. In this state, the catheter finger clamp assembly is longer as a whole, and the space for the arc required for flipping is larger. When assembling the catheter, more space needs to be left between the pump tube delivery line and the pump pipe positioning mechanism to facilitate the catheter finger clamp assembly to extend and complete the assembly. In this scheme, the finger clamping head is located on the side of the finger clamping connection part. When clamping the catheter, the flipping assembly drives the catheter finger clamp driving source to flip 90° to a horizontal state. At this time, the finger clamping head clamps the catheter downward, and then the catheter finger clamp driving source is flipped back to a vertical state. At this time, the catheter is also in a vertical state and the catheter connector is facing downward. In this state, plugging the catheter and the pump pipe can minimize the space occupied during plugging.

[0024] In the above assembly device of the pump tube assembly and the catheter, the bottom plate is provided with bottom plate limit blocks at both ends of the bottom plate slide rail, and a buffer is fixedly connected to the bottom plate limit blocks. The buffer can contact with both ends of the bottom plate to limit and buffer it.

[0025] In the assembly device of the pump tube assembly and the catheter, a baffle is provided on the side of the housing away from the column, and one end of the baffle is expanded outward. The baffle can prevent the catheter from sliding off the side of the housing, and the expansion can prevent the catheter from getting stuck here and causing damage when pulled.

[0026] In the above-mentioned assembly device of the pump tube assembly and the catheter, an auxiliary support block is arranged at the bottom of the rotating fixed block, and the auxiliary support block can play a supporting role for the rotating clamping finger assembly.

[0027] Compared with the prior art, the technical effects of the present invention are:

[0028] First, the feeding mechanism of the assembly device of the pump tube assembly and the catheter is above the pump tube positioning mechanism, the pump tube positioning mechanism accurately fixes the pump tube assembly, and the feeding mechanism plugs the catheter from above, which can effectively complete the automated assembly of the pump tube assembly and the catheter, and the material taking and installation assembly only requires one clamping and assembly action to complete the assembly of multiple sets of catheters and pump tube assemblies, without the need to clamp the catheter or pump tube assembly multiple times. The entire assembly process is simple and smooth, which further improves the assembly efficiency.

[0029] Second, the assembly device of the pump tube assembly and the catheter is provided with a material shifting mechanism to shift the catheter to prevent the catheter from being stuck during the assembly process. At the same time, the rotating clamping finger assembly drives the plug-in pump tube assembly to rotate so that the catheter falls in an orderly manner on one side of the pump tube conveying line, effectively reducing the interference between the catheter and various components. At the same time, the plug-in of the catheter is detected by the in-place detection component to screen out unqualified products, effectively improving the yield rate of the pump tube assembly.

[0030] Third, the assembly device of the pump tube assembly and the catheter optimizes the structure of the material picking installation assembly, and drives the flipping catheter clamp finger drive source through the flipping assembly, making the process from picking up materials, moving to plugging smoother, and reducing the space required during plugging.
