Description

Technical Field

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

[0002] Medical pump tubing assembly is a commonly used infusion device in the medical industry, such as Figure 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 connected to the catheter respectively. In order to ensure 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 application number "201620766238X" discloses a device for assembling a medical pump pipe and a catheter, including a picking mechanism for clamping the pump pipe and a tube clamping mechanism for clamping the catheter to be assembled. The picking mechanism includes picking clamping fingers for clamping the pump pipe, a clamping finger driving source for driving the picking clamping fingers to open and close, and a lifting cylinder for driving the 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 drive source for driving the tube clamping assembly to open and close. The 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 assembly device for the medical pump tube and the catheter requires multiple clamping and adjustment of the pump tube before the pump tube and the catheter can be assembled, resulting in low assembly efficiency. In addition, the loading and unloading of the pump tube requires additional control of the material-removing mechanism, resulting in complex assembly processes and equipment structures, and low assembly efficiency of the pump tube assembly.

[0005] Chinese invention patent application number "2022115815705" discloses an automated assembly device for medical pump tubes and catheters. The device comprises a base and a pump tube. A loading tray is mounted on the top of the base. The loading tray has a loading trough inside for stacking pump tubes, and a stop mechanism is provided at the bottom of the loading trough. The device also comprises a material transport ring that is sleeved onto the outside of the loading tray. A mounting bracket is mounted on the top of the base. The mounting bracket has two sets of plug-in mechanisms on the side of the mounting bracket near the material transport ring. The material transport ring cooperates with the material clamping hole to move the pump tube. The material clamping hole and the material feeding protrusion cooperate to clamp the tube while feeding. However, in this automated assembly device for medical pump tubes and catheters, the disc-shaped loading and unloading structure can only operate one pump tube at a time, and the overall assembly efficiency is still insufficient.

[0006] In addition, both of the above solutions involve taking out the pump connecting pipe separately and assembling 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 through the following technical solutions:

[0009] A device for assembling a pump tube assembly and a catheter comprises a feeding mechanism for gripping the catheter and a pump tube positioning mechanism, wherein the feeding mechanism comprises a gantry mounted above the pump tube positioning mechanism, a horizontal slide rail being provided on a crossbeam of the gantry, and a liftable material removal installation assembly being slidably mounted on the gantry;

[0010] The pump pipe positioning mechanism includes a base frame and a shell, a base plate is fixed on the base frame, a base plate slide is provided on the base plate, a positioning part support plate is slidably connected to the base plate slide, a plurality of groups of rotating clamping finger assemblies, a front bearing seat and a rear bearing seat are horizontally and equidistantly provided on the positioning part support plate, and a positioning part cylinder that drives 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 shafts respectively pass through the front bearing seat and the rear bearing seat 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 solution can slide back and forth. When the pump pipe assembly is delivered to its place, the positioning cylinder pushes the pump pipe positioning mechanism toward the pump pipe delivery line. The clamping finger drive source drives the clamping fingers to clamp the pump pipe and fix the side interface of the pump pipe vertically upward. The material taking installation assembly clamps the catheter and moves it above the clamping fingers, driving the catheter to descend and connect it with the side interface. Because the catheter is relatively long, during the process of the material taking installation assembly clamping the catheter and moving it, 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 fingers are opened, and the pump pipe positioning mechanism slides back and retracts to prevent the pump pipe positioning mechanism from touching the pump pipe assembly. The entire 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 assembly efficiency.

[0013] The assembly device of the above-mentioned pump tube assembly and catheter also includes a material diverting mechanism, which includes a column, a push plate and a push plate driving source that drives the push plate to slide horizontally. A locking block is provided on the column, and a horizontally arranged material diverting pad is fixedly connected to the locking block. The bottom surface of the material diverting pad is fixedly connected to the push plate driving source; the push plate is horizontally arranged above the shell, and includes a connecting part, a horizontal part and a downward-inclined 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 shell and does not touch it, and the other part is close to the side of the 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. During the pushing process, 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, 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 clamping head, a transition section and a clamping finger connecting section. The clamping head is provided with a first recess for accommodating the large interface of the pump tube, a through groove portion for clamping the side interface of the pump tube, a second recess for accommodating the small interface of the pump tube, and a clamping head 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 to 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 is adapted to the position of the chuck, and through detection observation holes are provided on the left and right sides of the chuck.

[0017] A transition section is set between the connecting section of the chuck and the clamping finger to increase the length of the clamping finger, which is convenient for clamping and can also avoid 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 chuck of the clamping finger form a cavity corresponding to the shape of the pump pipe for accommodating the pump pipe and positioning it. The chuck limit block can press against the end of the small interface of the pump pipe when the rotating clamping finger assembly is extended 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 inserted, 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 inserted, the rotating clamping finger assembly drives the catheter to rotate 90°. At this time, the camera detection assembly slides to the top of the chuck, and performs video detection through the through detection observation hole to determine whether the catheter and the pump pipe are inserted 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 slider compatible with the slide rail is fixedly connected to the material picking translation plate, and 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. The left and right ends of the material picking lifting plate are respectively fixedly connected to a flip support plate, and a flip plate is flipably connected between the two flip support plates. A flip assembly that drives the flip plate to flip is fixedly connected to the outer side of the flip support plate, and several groups of catheter clamping finger assemblies are equidistantly fixed on the flip plate.

[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 in. The catheter is generally placed horizontally on the platform. When the material taking and installation assembly clamps the catheter, the interface of the catheter is also in a horizontal state. In order to facilitate plugging in, 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] By cooperating with 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 flips 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 clamping assembly includes a catheter finger clamping finger and a catheter finger clamping driving source that drives the catheter finger clamping finger to open and close. The catheter finger clamping finger includes a finger clamping connecting part and a finger clamping head part. The finger clamping head part is located on the side of the finger clamping connecting part. When the catheter finger clamping assembly is closed, the clamped catheter is located on the side of the catheter finger clamping driving source and is parallel to the catheter finger clamping driving source.

[0023] In common catheter finger clamp assemblies, the catheter finger clamp drive source is vertically arranged, the finger clamp head is located at the bottom end of the finger clamp connection part, and the installation direction of the catheter finger clamp is consistent with the rod head direction of the catheter finger clamp drive 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 insertion of the catheter finger clamp assembly to complete the assembly. In this solution, the finger clamp head is located on the side of the finger clamp connection part. When clamping the catheter, the flipping assembly drives the catheter finger clamp drive source to flip 90° to a horizontal state. At this time, the finger clamp head faces downward to clamp the catheter, and then the catheter finger clamp drive source is flipped back to a vertical state. At this time, the catheter is also in a vertical state and the catheter connector faces downward. In this state, plugging the catheter and the pump pipe can minimize the space occupied during plugging.

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

[0025] In the aforementioned assembly device for the pump tube assembly and catheter, a baffle is provided on the side of the housing away from the upright post, with one end of the baffle flared outward. The baffle prevents the catheter from sliding off the side of the housing, and the flared end prevents the catheter from getting stuck there and causing damage when pulled.

[0026] In the assembly device of the pump tube assembly and the catheter, an auxiliary support block is provided at the bottom of the rotating fixed block, which can support the rotating clamping finger assembly.

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

[0028] First, the loading 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 loading mechanism plugs the catheter from above, which can effectively complete the automated assembly of the pump tube assembly and the catheter. Moreover, the material collection 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, further improving 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 getting stuck during the assembly process. At the same time, the rotating clamping finger assembly drives the connected 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 connection of the catheter is inspected by the in-place detection assembly 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.

DETAILED DESCRIPTION

When clamping the catheter 8, the flip assembly 37 drives the catheter finger clamping drive source 381 to flip 90° to a horizontal state. At this time, the clamping finger clamping portion 3812 clamps the catheter 8 downward, and then the catheter finger clamping drive source 381 is flipped back to a vertical state.
