Description

Technical Field

[0001] The present invention relates to the technical field of production of nursing products, in particular to the production of flexible containers, specifically to automated production equipment and a production process for a medical liquid collection bag. Background Art

[0002] Medical fluid collection bags, as an important auxiliary device, play an indispensable role. In particular, urine collection bags are designed to meet the actual needs of patients in terms of excretion, especially those with limited mobility, long-term bedridden patients, or those who require continuous medical care. This type of fluid collection bag not only greatly improves the quality of life of patients, but also reduces the workload of medical staff and improves nursing efficiency.

[0003] The production process of urine collection bags is a complex and delicate process involving multiple key steps. After the heat pressing of the front bag body and the rear bag body, two insertion holes will be left at the top and bottom for the insertion of the catheter and the drainage valve respectively. Figure 1 As shown, after the urine bag body 1a is hot-pressed, the catheter insertion hole 1b at the top and the drainage valve insertion hole 1c at the bottom are retained; in the traditional urine collection bag production process, the insertion operation of these two insertion holes is mainly completed manually. Although manual insertion can meet production needs to a certain extent, it has many shortcomings.

[0004] First, the consistency and accuracy of manual intubation is difficult to guarantee. Due to factors such as the operator's skill level and fatigue level, the position, angle and depth of the intubation may vary, thus affecting the sealing and use effect of the urine collection bag. Secondly, the production efficiency of manual intubation is relatively low and cannot meet the needs of large-scale production.

[0005] Therefore, in order to improve the production efficiency of urine collection bags, ensure product quality and hygiene standards, it is particularly important to develop a medical liquid collection bag production equipment and production process that can automatically complete the catheter and drainage valve insertion operations.

[0020] In a preferred embodiment of the present invention, the heating plate is heated by heat radiation or heat conduction.

[0021] The present invention provides a production process of an automated production device for a medical liquid collection bag, comprising the following steps:

[0022] S1. Use the mechanical arm to make the vacuum suction cups on the top of the mechanical arm vacuum-absorb the urine bags on the material-taking platform at one time, and transfer the urine bags to the urine bag positioning mechanisms, vertically fit and position them on one side of the positioning plate, and vacuum-absorb the urine bags on one side of the positioning plate through the vacuum suction holes;

[0023] S2. Inflate the inside of the urine bag through the dual-axis translation inflation mechanism. While inflating the opening, use the mechanical arm and several vacuum suction cups to vacuum-absorb several catheters and several drainage valves on the material-taking platform and transfer them to several urine bag positioning mechanisms.

[0024] S3. After the urine bag is inflated and opened, one end of the drainage valve is placed and inserted into the socket at one end of the urine bag through the mechanical arm and the vacuum suction cup. The vacuum suction cup is driven to rotate through the rotating assembly, driving the drainage valve to rotate one circle, and the drainage valve socket of the urine bag is heated through the heating plate;

[0025] S4, after the discharge valve is inserted into the hole, the two sides of the urine bag are clamped by the clamping roller assembly, and the positioning plate is driven to rotate 180 degrees by the first servo motor, and the surface of the urine bag is rolled by the clamping roller assembly to gradually discharge the gas, and the rolling stops after half of the surface of the urine bag is rolled;

[0026] S5. Place one end of the catheter into the socket at the other end of the urine bag through the mechanical arm and the vacuum suction cup. Drive the vacuum suction cup to rotate through the rotating assembly, drive the catheter to rotate one circle, and heat the catheter socket of the urine bag through the heating plate.

[0027] S6, rolling the remaining part of the urine bag surface by clamping and rolling the assembly to discharge the remaining gas inside the urine bag;

[0028] S7. Drive the retrieval disk to rotate through the power source, retrieve several urine bag positioning mechanisms that have absorbed the completed catheters and drainage valve plug-in urine bags, retrieve several urine bag positioning mechanisms that have not absorbed the urine bags, repeat steps S1-S6 to realize the automated production of medical liquid collection bags.

[0029] In a preferred embodiment of the present invention, in step S1, the urine bag is heat-pressed on the front bag surface and the rear bag surface, and holes are left on the top and the bottom; in step S2, the inflated gas is an inert gas; and the sides of the insertion ends of the catheter and the drainage valve are coated with medical sealant.

[0030] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0031] The present invention provides an automated production device and a production process for a medical liquid collecting bag. When a urine bag to be intubated, a urinary catheter with medical sealant applied to the insertion end, and a liquid discharge valve are placed on a material taking platform respectively, the automation of material taking, placing, bag supporting, intubation, colloid solidification and other steps in the production process of the medical liquid collecting bag is achieved through the cooperation of a mechanical arm, a vacuum suction cup, a rotating assembly, a dual-axis translation inflation mechanism and a urine bag positioning mechanism. This significantly improves production efficiency and reduces manual intervention while avoiding differences in urine bag intubation quality caused by manual intubation, thereby helping to improve the production quality and consistency of urine bags.

[0032] In the present invention, after one end of the urinary catheter or the drainage valve is placed and inserted into the insertion hole at one end of the urine bag, the one end of the urinary catheter or the drainage valve is rotated in the insertion hole for one circle, so that the medical sealant is more evenly distributed on the contact surface between the urinary catheter or the drainage valve and the urine bag, thereby avoiding the formation of glue tumors, and the glue can be evenly squeezed and more tightly attached to the contact surface between the urinary catheter or the drainage valve and the urine bag, which helps to improve the sealing performance of the medical liquid collection bag.

[0033] In the present invention, after the catheter or the drainage valve is inserted into the urine bag on the front side of the positioning plate, the setting of the heating plate can promote the curing of the medical sealant, improve the sealing performance of the insertion part, and thus ensure the production quality of the medical liquid collection bag.

[0034] In the present invention, after one end of the catheter or the drainage valve is placed and inserted into the insertion hole at one end of the urine bag, the insertion hole is first heated and then the gas is discharged. This can avoid the situation where the catheter or the drainage valve loses support due to the discharge of gas before the glue is cured, resulting in tilting or position displacement. This ensures that the curing process of the glue is not disturbed by the gas discharge, and ensures that the sealing performance between the catheter or the drainage valve and the urine bag reaches the optimal state, thereby improving the stability and reliability of the process while also helping to improve the overall quality and performance of the product.

[0035] In the present invention, by installing a clamping and rolling assembly on the side of the positioning plate, with the cooperation of the flip cylinder, the movable rod and the fixed rod, the two sides of the urine bag on the front of the positioning plate can be clamped. When the urine bag needs to be vented, through the cooperation of the second servo motor, the translation groove, the threaded rod, the drive block and the exhaust roller, not only can the surface of the urine bag be clamped after intubation to prevent the urine bag from shifting or deforming during the rolling process, but the gas inside the urine bag can also be gradually discharged by rolling, ensuring that the shape and size of the urine bag are stable after intubation.

[0036] In the present invention, a dual-axis translation inflation mechanism is arranged on the support plate. When the urine bag is adsorbed on the front side of the positioning plate, the support plate, the first cylinder, the limit rod, the moving block, the second cylinder and the connecting plate can cooperate to drive the air outlet head and the drill pipe to perform translational positioning in the Y-axis and Z-axis directions. At the same time, since the bottom of the drill pipe is conical, after touching the insertion hole of the urine bag downward, it can gradually penetrate into the urine bag, and with the cooperation of the gas output device externally connected to the top of the air outlet head, the urine bag can be inflated. The surface tension formed can ensure that the mouth of the urine bag is fully opened, thereby facilitating the subsequent intubation operation and avoiding the difficulty of intubation caused by the adhesion of the urine bag.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances. Example 1

[0049] like Figure 2 , Figure 3 and Figure 4 As shown, an automated production device for medical liquid collection bags comprises: a material taking platform 1 for placing urine bags, urinary catheters and drainage valves, a workbench 2 arranged on one side of the material taking platform 1, and two mechanical arms 3 located between the material taking platform 1 and the workbench 2 for transporting and placing urine bags, urinary catheters and drainage valves;

[0050] A vacuum suction cup 31 for achieving vacuum adsorption and a rotating assembly 32 for driving the vacuum suction cup 31 to rotate and adjust the angle are installed on the top of the robot arm 3; a support plate 4 is fixed on the top of the workbench 2, a retrieval plate 5 is sleeved on the bottom of the support plate 4, and a power source for driving the retrieval plate 5 to achieve rotational motion is installed on the top of the workbench 2;

[0051] A biaxial translational inflation mechanism 6 for inflating the inside of the urine bag is installed on the top of the support plate 4, and a plurality of mounting plates 7 are fixed on the side of the retrieval plate 5, and a urine bag positioning mechanism 8 is installed on the mounting plates 7;

[0052] The urine bag positioning mechanism 8 includes: a first servo motor 81 installed on the back of the mounting plate 7, a positioning plate 82 fixed to the output end of the first servo motor 81, and a plurality of vacuum suction holes 83 provided on the front of the positioning plate 82 for achieving vacuum adsorption; a heating plate 84 is provided on the front of the positioning plate 82 near the top and the bottom, and a clamping and rolling assembly for clamping and rolling the surface of the urine bag is installed on the side of the positioning plate 82.

[0053] It should be noted that there are four vacuum suction cups 31 on each robot arm 3, and each two vacuum suction cups 31 form a group, which are used to absorb a urine bag or two urinary catheters or two drainage valves; one end of the vacuum suction cup 31 is connected to an external vacuum extraction device (such as a vacuum pump) through a pipeline to form a relatively closed vacuum system. When the vacuum extraction device is started, the air pressure in the system decreases, forming a negative pressure, which causes the air pressure difference between the vacuum suction cup 31 and the object to increase, thereby achieving an adsorption effect; a gas flow channel with a vacuum suction hole 83 is provided in the positioning plate 82, and a sleeve-shaped flow channel is formed from the middle of the positioning plate 82 to the mounting plate 7, and an external vacuum extraction device is connected through a joint on the back of the mounting plate 7;

[0054] The output end of the first servo motor 81 is fixed to the middle of the positioning plate 82; the specific structure of the rotating component 32 is a mechanical mechanism or power (such as a servo motor) in the prior art that can transmit rotational motion, which is common knowledge in the field, so this application no longer explains the control method and structure in detail, and no detailed description is made here; the number of the dual-axis translation inflation mechanism 6 and the urine bag positioning mechanism 8 are both two groups; the heating plate 84 is heated by heat radiation or heat conduction. When the catheter or the drainage valve is inserted into the urine bag on the front side of the positioning plate 82, the setting of the heating plate 84 can promote the curing of the medical sealant and improve the sealing performance of the insertion site, thereby ensuring the production quality of the medical collection bag.

[0055] Specifically, when the urine bag to be inserted, the catheter with medical sealant coated on the insertion end, and the drainage valve are placed on the material collection table 1 respectively, the robot arm 3, the vacuum suction cup 31, the rotating assembly 32, the dual-axis translation inflation mechanism 6 and the urine bag positioning mechanism 8 cooperate to achieve the automation of the steps of material collection, placement, bag support, insertion and colloid solidification in the production process of the medical liquid collection bag. While avoiding the difference in the quality of urine bag insertion caused by manual insertion, the production efficiency is significantly improved and manual intervention is reduced, which helps to improve the production quality and consistency of urine bags.

[0056] In this embodiment, the clamping roller assembly includes: a fixed rod 811 fixed on both sides of the positioning plate 82, a movable rod 812 hinged at the bottom of the fixed rod 811, and a flip cylinder 813 fixed on one side of the fixed rod 811; the output end of the flip cylinder 813 is fixed to the rotating shaft of the hinge point of the fixed rod 811 and the movable rod 812.

[0057] The clamping roller assembly also includes: a second servo motor 814 installed at one end of the movable rod 812, a translation groove 815 opened on one side of the movable rod 812, and a threaded rod 816 rotatably connected to the inner side of the translation groove 815; the output end of the second servo motor 814 is fixed to one end of the threaded rod 816, and the side of the threaded rod 816 is threadedly connected with a driving block 817, and an exhaust roller 818 is arranged between adjacent movable rods 812, and both ends of the exhaust roller 818 are rotatably connected to one side of the driving block 817.

[0058] It should be noted that the number of the fixed rod 811, the movable rod 812, the flip cylinder 813, the second servo motor 814, the translation slot 815, the threaded rod 816, the drive block 817 and the exhaust roller 818 are all two; one side of the movable rod 812 is fixed to the side of the rotating shaft, the front side of the fixed rod 811 is flush with the front side of the positioning plate 82, and the angle between the movable rod 812 and the fixed rod 811 varies from 0 to 90°; the height dimension of the drive block 817 is the same as the height dimension of the translation slot 815.

[0059] Specifically, by controlling the flip cylinder 813, the rotating shaft of the hinge point is driven to rotate, so that it drives the movable rod 812 to flip upward 90°, and then the two sides of the urine bag on the front of the positioning plate 82 can be clamped. When the urine bag needs to be exhausted, the second servo motor 814 is controlled to drive the threaded rod 816 in the translation groove 815 to rotate, which can drive the driving block 817 threadedly connected to its side to translate along the length direction of the threaded rod 816, and then the exhaust roller 818 between adjacent movable rods 812 can be driven to move synchronously. Since the two ends of the exhaust roller 818 are rotatably connected to one side of the driving block 817, when the driving block 817 drives it to move, the exhaust roller 818 will rotate along the surface of the urine bag, so that it can not only clamp the surface of the urine bag after intubation to prevent the urine bag from shifting or deforming during rolling, but also gradually discharge the gas inside the urine bag through rolling, to ensure that the shape and size of the urine bag are stable after intubation.

[0060] like Figure 5 As shown, in this embodiment, the dual-axis translation inflation mechanism 6 includes: a support frame 61 fixed on the top of the support disk 4, a support plate 62 fixed on one side of the support frame 61, and a first cylinder 63 fixed on one side of the support plate 62; a plurality of limit rods 64 are fixed on the other side of the support plate 62, and a moving block 65 is sleeved on the side of the plurality of limit rods 64, and the output end of the first cylinder 63 is fixed to one side of the moving block 65; a second cylinder 66 is fixed on the other side of the moving block 65, and a connecting plate 67 is fixed to the output end of the second cylinder 66, and an air outlet head 68 is installed at one end of the connecting plate 67, and a brazing tube 69 is fixed to the bottom end of the air outlet head 68.

[0061] It should be noted that the bottom of the brazing tube 69 is conical and faces the middle of the positioning plate 82. The brazing tube 69 is a hollow structure, and the top of the gas outlet head 68 is connected to the gas output device (such as an air pump and a gas storage tank) through a pipeline.

[0062] Specifically, when the urine bag is adsorbed on the front side of the positioning plate 82, the first cylinder 63 is controlled to extend or contract, driving the moving block 65 at the output end to slide on the side of the limiting rod 64, and then driving the air outlet head 68 and the brazing tube 69 to achieve positioning relative to the Y-axis direction of the urine bag. The second cylinder 66 is controlled to extend, driving the connecting plate 67 at the output end to translate downward, and driving the air outlet head 68 and the brazing tube 69 on the connecting plate 67 to achieve translation in the Z-axis direction. Since the bottom of the brazing tube 69 is conical, after contacting the insertion hole of the urine bag downward, it can gradually penetrate into the urine bag, and with the cooperation of the gas output device externally connected to the top of the air outlet head 68, the urine bag can be inflated. The surface tension formed can ensure that the mouth of the urine bag is fully opened, thereby facilitating the subsequent intubation operation and avoiding the difficulty of intubation caused by the fit of the urine bag.

[0063] like Figure 6 As shown, in this embodiment, the power source includes: a driving motor 9 and a fixing frame 91 fixed on the top of the workbench 2, a sleeve 92 rotatably connected to the top of the fixing frame 91, and a power transmission mechanism 93 installed at the output end of the driving motor 9 for realizing rotation transmission to the sleeve 92; the top of the sleeve 92 is fixed to the bottom of the retrieval plate 5, and a connecting column 94 is fixed to the top of the fixing frame 91, and the top of the connecting column 94 is fixed to the bottom of the support plate 4.

[0064] It should be noted that the specific structure of the power transmission mechanism 93 is a mechanical mechanism in the prior art that can transmit the rotational motion of the drive motor 9 (such as gear transmission or pulley transmission), which is common knowledge in the art. Therefore, this application no longer explains the control method and structure in detail, and no detailed description is made here; the sleeve 92 is located on the side of the connecting column 94, and the sleeve 92, the connecting column 94, the retrieval plate 5 and the support plate 4 are coaxially arranged.

[0065] Specifically, by providing rotational power through the driving motor 9, with the cooperation of the power transmission mechanism 93, the rotational motion can be transmitted to the sleeve 92, so that the sleeve 92 rotates on the top of the fixed frame 91 and the side of the connecting column 94, and the connecting column 94 and the top support plate 4 will remain stationary, and then the sleeve 92 will drive the top retrieval plate 5 to rotate synchronously, which can realize the rapid retrieval and replacement of the urine bag positioning mechanism 8, improve the flexibility of the equipment, ensure the continuity of the production process, and thus improve the production efficiency.

[0066] In this embodiment, a control system 10 for realizing full-automatic production using a programmable controller is installed on the workbench 2 .

[0067] It should be noted that the control system 10 is electrically connected to the control modules of the robot arm 3, the vacuum suction cup 31, the first cylinder 63, the second cylinder 66, the air outlet head 68, the first servo motor 81, the vacuum suction hole 83, the heating plate 84, the flip cylinder 813, the second servo motor 814 and the drive motor 9 respectively; the control method of the control system 10 and the control circuit for realizing fully automatic production belong to the prior art and can be realized by programming by technicians in this field. They are common knowledge in this field. Therefore, this application no longer explains the control method and module in detail, and no detailed description is made here; it realizes fully automatic production control of the equipment, improves the intelligence level of the equipment, and facilitates the monitoring and adjustment of the production process.

[0068] In this embodiment, a placement rack 11 for placing a urine bag and a placement frame 12 for placing a urinary catheter and a drainage valve are fixed on the material taking platform 1.

[0069] It should be noted that there are two placement racks 11. The placement racks 11 are used to stack several urine bags to be inserted into the holes in a flat surface after the front bag surface and the rear bag surface are hot-pressed, so that it is convenient for the vacuum suction cup 31 to vertically absorb the surface of the urine bags; the placement frame 12 is used to vertically hang the catheter and the drainage valve to be inserted into the holes, and the insertion ends of the catheter and the drainage valve coated with medical sealant are placed toward the bottom in the vertical direction, so that it is convenient for the vacuum suction cup 31 to vertically absorb the top of the catheter and the drainage valve.

[0070] The present invention provides a production process of an automated production device for a medical liquid collection bag, comprising the following steps:

[0071] S1, using the mechanical arm 3, the four vacuum suction cups 31 at the top thereof vacuum absorb the two urine bags on the material taking platform 1 at a time, and transfer the two urine bags to the two urine bag positioning mechanisms 8, vertically fit and position them on one side of the positioning plate 82, and vacuum absorb the urine bags on one side of the positioning plate 82 through a plurality of vacuum suction holes 83;

[0072] S2, inflate the inside of the urine bag through the dual-axis translation inflation mechanism 6, and at the same time, vacuum-absorb the two urinary catheters and two drainage valves on the material-taking platform 1 through the mechanical arm 3 and four vacuum suction cups 31, and transfer them to the two urine bag positioning mechanisms 8;

[0073] S3, after the urine bag is inflated and opened, one end of the drainage valve is placed and inserted into the plug hole at one end of the urine bag through the mechanical arm 3 and the vacuum suction cup 31, and the vacuum suction cup 31 is driven to rotate through the rotating component 32, driving the drainage valve to rotate one circle, and the drainage valve plug hole of the urine bag is heated through the heating plate 84;

[0074] S4, after the discharge valve is inserted into the hole, the two sides of the urine bag are clamped by the clamping roller assembly, and the first servo motor 81 drives the positioning plate 82 to rotate 180 degrees, and the surface of the urine bag is rolled by the clamping roller assembly to gradually discharge the gas, and the rolling stops after half of the surface of the urine bag is rolled;

[0075] S5. Place one end of the catheter into the insertion hole at the other end of the urine bag through the mechanical arm 3 and the vacuum suction cup 31. Drive the vacuum suction cup 31 to rotate through the rotating assembly 32, drive the catheter to rotate one circle, and heat the catheter insertion hole of the urine bag through the heating plate 84.

[0076] S6, rolling the remaining part of the urine bag surface by clamping and rolling the assembly to discharge the remaining gas inside the urine bag;

[0077] S7. Drive the retrieval disk 5 to rotate through the power source, retrieve several urine bag positioning mechanisms 8 that have absorbed the completed urinary catheters and drainage valve plug holes, retrieve several urine bag positioning mechanisms 8 that have not absorbed the urine bags, repeat steps S1-S6 to realize the automated production of medical liquid collection bags.

[0078] It should be noted that in step S1, the urine bag is heat-pressed on the front bag surface and the rear bag surface, and holes are left on the top and the bottom; in step S2, the inflation gas is an inert gas, such as helium, argon or xenon; the sides of the insertion end of the catheter and the drainage valve are coated with medical sealant.

[0079] Specifically, in steps S3 and S5, after inserting one end of the catheter or the drainage valve into the insertion hole at one end of the urine bag, the one end of the catheter or the drainage valve is rotated in the insertion hole for one circle, so that the medical sealant is more evenly distributed on the glue contact surface with the urine bag, thereby avoiding the formation of glue tumors, and the glue can be evenly squeezed and more tightly fitted on the contact surface between the catheter or the drainage valve and the urine bag, which helps to improve the sealing performance of the medical liquid collection bag.

[0080] Specifically, in steps S4 and S6, after one end of the catheter or the drainage valve is placed and inserted into the socket at one end of the urine bag, the socket is first heated and then the gas is discharged. This can prevent the catheter or the drainage valve from losing support due to the discharge of gas before the glue has solidified, resulting in tilting or position shifting. This ensures that the curing process of the glue is not disturbed by the discharge of gas, and ensures that the sealing performance between the catheter or the drainage valve and the urine bag is in the best state, thereby improving the stability and reliability of the process while also helping to improve the overall quality and performance of the product.

[0081] This embodiment is basically the same as the embodiment 1, except that: the number of vacuum suction cups 31 on each robot arm 3 is six; the number of the dual-axis translation inflation mechanism 6 and the number of the urine bag positioning mechanism 8 are three.

[0082] It should be noted that, by increasing the number of vacuum suction cups 31, biaxial translation inflation mechanisms 6 and urine bag positioning mechanisms 8, it is possible to perform catheterization operations on three urine bags at a time, effectively increasing production capacity.

[0084] It should be noted that, by increasing the number of vacuum suction cups 31, biaxial translation inflation mechanisms 6 and urine bag positioning mechanisms 8, it is possible to perform catheterization operations on four urine bags at a time, effectively increasing production capacity.
