Description

Technical Field

[0001] The present invention relates to the technical field of infusion sets, in particular to an automatic assembly device for disposable infusion sets. Background Art

[0002] Disposable infusion sets are a common medical consumable, primarily used for intravenous infusion in hospitals. They consist of a syringe needle, an infusion hose, and a bottle puncture device. Traditionally, disposable infusion sets are made of PVC (polyvinyl chloride). Disposable infusion sets are essential tools in the medical field, and their safety and effectiveness are directly related to the health and safety of patients. In existing technology, the assembly of infusion hoses and bottle puncture devices is mostly performed manually. Without professional training or unskilled assemblers, they may not be able to complete the assembly task accurately and quickly, increasing the risk of operational errors. Therefore, operating procedures and precautions must be strictly adhered to during use.

[0003] There are still the following defects in specific use:

[0004] 1. Disposable infusion sets are most commonly assembled manually. During the manual assembly of the infusion hose and the bottle stopper puncture device, although the workshop has been sterilized, due to inadequate protective measures, the hands of the personnel are likely to touch the infusion hose and the bottle stopper puncture device, which can easily lead to contamination of the product with bacteria, hair and other foreign matter, thus affecting the safety of the disposable infusion set.

[0005] 2. During the assembly process of the infusion hose and the bottle cork puncture device, since the infusion hose and the bottle cork puncture device are small and delicate, when the personnel manually insert the bottle cork puncture device into the interior of the infusion hose, the bottle cork puncture device is likely to clash with the inner wall of the infusion hose interface, which may easily cause the interior of the infusion hose interface to be deformed and damaged. As a result, the connection between the infusion hose and the puncture device may not be tight enough, and there is a risk of leakage or falling off.

[0042] refer to Figure 2 , the rubber roller 48 is rotatably connected to the top of the support plate 49, and the size of the support plate 49 is adapted to the distance between the two special-shaped blocks 45;

[0043] Summary 1: Compared with the prior art, the connection ports of the infusion hose 2 and the bottle cork piercer 3 cannot be effectively aligned when personnel install them. The present invention uses the clamping and correction mechanism 4 to enable the connection between the infusion hose 2 and the bottle cork piercer 3 to be maintained on the same water surface, ensuring that the inner wall of the infusion hose 2 can fit tightly with the bottle cork piercer 3, improving the sealing between the infusion hose 2 and the bottle cork piercer 3, and preventing the drug solution from leaking from the connection during the infusion process. In addition, the clamping and correction mechanism 4 improves the sealing between the bottle cork piercer 3 and the bottle cork piercer 3, which not only maintains the purity and effectiveness of the drug solution, but also avoids pollution and waste caused by leakage at the connection between the infusion hose 2 and the bottle cork piercer 3.

[0044] refer to Figures 3 to 5 , the assembly mechanism 5 is used to ensure that the bottle stopper piercer 3 and the infusion hose 2 can be effectively assembled during the assembly process;

[0045] refer to Figures 3 to 5The assembly mechanism 5 includes a fixed platform 51 slidably connected to the bottom inner side of the mounting platform 1, a supporting platform 52 is fixedly connected to the inner wall of the mounting platform 1, a loading plate 53 is fixedly connected to the upper surface of the fixed platform 51, and a fixed rod 54 is symmetrically fixedly connected to the upper surface of the fixed platform 51. A torsion spring 55 is sleeved on the outer wall of the fixed rod 54, and a hinged plate 56 is rotatably connected to the outer wall of the torsion spring 55. The end of the hinged plate 56 away from the fixed rod 54 is fixedly connected to a clamping block 57, and a fixed plate 58 is fixedly connected to the side wall of the clamping block 57. A sliding rod 59 is rotatably connected to the interior of the fixed plate 58, and a spring 510 is sleeved on the end of the sliding rod 59 close to the fixed plate 58. A rubber plate 511 is fixedly connected to the end of the sliding rod 59 away from the spring 510. The top of the mounting platform 1 is slidably connected to a cover plate 512;

[0046] refer to Figure 5 , the two ends of the torsion spring 55 are fixedly connected to the fixed platform 51 and the hinge plate 56 respectively, and the two ends of the spring 1 510 are fixedly connected to the fixed plate 1 58 and the slide rod 59 respectively;

[0047] refer to Figure 3 , the outer end of the clamping block 57 is provided with a second inclined surface, and the side of the cover plate 512 close to the clamping block 57 is provided with a third inclined surface. The dimensions of the fixing platform 51 and the supporting platform 52 are adapted to the internal dimensions of the mounting platform 1;

[0048] It should be noted that the cover 512 is controlled by an external control device. The function of the cover 512 is similar to that of an electric slide. The working principle of the electric slide mainly depends on the coordinated action of its internal components, including motors, battery packs, controllers, drive systems and manipulators. When the user issues forward or acceleration instructions through the manipulator, these instructions will be received and processed by the controller. The controller outputs corresponding current signals to the motor according to the instructions. The stator inside the motor generates a magnetic field, which interacts with the magnets inside the rotor to generate a rotational force. The rotational force is transmitted to the slide tire through the drive system, pushing the slide forward or accelerating.

[0049] Summary 2: Compared with the prior art, in which personnel manually assemble the infusion hose 2 and the bottle cork piercer 3, it is easy to cause the inner wall of the connection of the infusion hose 2 to be deformed or damaged. Therefore, the assembly mechanism 5 of the present invention can achieve the effect of automatic assembly of the infusion hose 2 and the bottle cork piercer 3, avoiding the personnel from assembling the infusion hose 2 and the bottle cork piercer 3 by plugging, thereby improving the efficiency of assembling the infusion hose 2 and the bottle cork piercer 3. In addition, the assembly mechanism 5 can make the bottle cork piercer 3 evenly inserted into the interior of the infusion hose 2, and the clamping block 57 and the rubber plate 511 arranged inside the assembly mechanism 5 are pressed on the outer wall of the infusion hose 2, which not only improves the fit of the connection between the infusion hose 2 and the bottle cork piercer 3, but also improves the production quality of a one-time infusion mechanism.

[0050] refer to Figures 6 to 8 , a protective mechanism 6, which is used to protect the bottle stopper puncture device 3 and the infusion hose 2 during the assembly process to prevent bacteria in the environment from contaminating them;

[0051] refer to Figures 6 to 8 The protective mechanism 6 includes a second fixed plate 61 symmetrically fixedly connected to the mounting platform 1, a gear rod 62 is rotatably connected to the interior of the second fixed plate 61, a rectangular tooth plate 63 is symmetrically fixedly connected to the side wall of the mounting platform 1, and the end of the gear rod 62 away from the second fixed plate 61 is fixedly connected to a diagonal rod 64, a limiting groove 65 is symmetrically provided at the bottom of the side wall of the mounting platform 1, a slide plate 66 is slidably connected to the inside of the limiting groove 65, a circular ring plate 67 is fixedly connected to the top of the slide plate 66, and a slider 68 is symmetrically fixedly connected to the inner side of the circular ring plate 67, and a rubber plate 2 69 is fixedly connected to the end of the slide plate 66 away from the second fixed plate 61, a first bracket 610 is fixedly connected to the side wall of the slide plate 66, and an alcohol nozzle 611 is fixedly connected to the end of the first bracket 610 away from the second fixed plate 61, an electrical block 612 is fixedly connected to the side wall of the alcohol nozzle 611 arranged on the right side of the mounting platform 1, and an electrical slot 613 is provided on the side wall of the alcohol nozzle 611 arranged on the left side of the mounting platform 1;

[0052] refer to Figures 6 and 7 , the rectangular tooth plate 63 is meshed with the gear rod 62 , the slider 68 is slidably connected with the diagonal rod 64 , and the size of the electrical slot 613 is adapted to the size of the electrical block 612 ;

[0053] refer to Figures 6 to 8 , the two alcohol nozzles 611 are on the same horizontal plane, and the diagonal rod 64 rotates inside the circular plate 67;

[0054] It should be noted that the alcohol spray nozzle 611 is controlled by an external control device. Its functionality is similar to that of an electric spray bottle, whose operating principle relies primarily on the synergy of its core components: the motor, pump, connecting pipes, and spray nozzle. When the user activates the electric spray bottle, the motor begins operating, transmitting power to the pump via a transmission mechanism. Driven by the motor, components such as the piston and diaphragm within the pump reciprocate, generating a pressure differential. This pressure differential draws liquid from the reservoir into the pump, where it is pressurized. The pressurized liquid is then delivered to the spray nozzle through the connecting pipe. During this process, the liquid pressure is maintained, providing the power for subsequent atomization. When the liquid reaches the spray nozzle, the nozzle's special internal structure (such as the high-speed airflow at the nozzle) rapidly disperses the liquid into tiny particles, forming a uniform mist spray. Factors such as the nozzle design and gas inlet of the nozzle play a key role in this process.

[0055] Summary 3: Compared with the prior art, in the process of assembling the infusion hose 2 and the bottle stopper piercer 3, it is easy for the connection between the infusion hose 2 and the bottle stopper piercer 3 to be contaminated with bacteria, hair and foreign matter. The protective mechanism 6 of the present invention sprays the connection between the infusion hose 2 and the bottle stopper piercer 3 being assembled with alcohol, thereby preventing foreign matter in the air from adhering to the connection between the infusion hose 2 and the bottle stopper piercer 3, avoiding the contamination of the infusion hose 2 and the bottle stopper piercer 3 by bacteria and hair, and ensuring the safety of the disposable infusion set. In addition, the rubber plate 2 69 arranged inside the protective mechanism 6 is in contact with the outer wall of the bottle stopper piercer 3, thereby achieving the effect of fixing the bottle stopper piercer 3, avoiding the bottle stopper piercer 3 from falling under the interference of the infusion hose 2 and causing contamination. Finally, the alcohol nozzle 611 arranged by the protective mechanism 6 is semicircular, thereby achieving all-round spraying and disinfection of the connection between the infusion hose 2 and the bottle stopper piercer 3.

[0056] The complete working principle and steps of the above embodiment are as follows:

[0057] Initial definition: the special-shaped block 45 is in contact with the lower side of the middle portion of the curved plate 47, the rubber roller 48 provided at the bottom end of the curved plate 47 is in contact with the bottom of the contact block 410, the limit block 46 is in an uncompressed state, the control button 42 is not in contact with the bottom end of the support plate 49, the torsion spring 55 is in a relaxed state, the spring 1 510 is in an unstretched state, the annular plate 67 is at the end of the diagonal rod 64 close to the fixed plate 2 61, and the two alcohol spray nozzles 611 are in an unclosed state;

[0058] When using:

[0059] Steps for clamping and positioning the bottle stopper piercer 3 so that the bottle stopper piercer 3 can be effectively aligned with the infusion hose 2:

[0060] like Figure 2 As shown, the personnel places the bottle cork piercer 3 above the rubber roller 48 provided on the top of the support plate 49, so that the bottle cork piercer 3 hits the rubber roller 48 downward under the action of its own gravity, so that the rubber roller 48 drives the support plate 49 to move downward between the two special-shaped blocks 45 and the two limit blocks 46, and then the support plate 49 drives the contact block 410 to move downward synchronously. In the process of the contact block 410 moving downward, the contact block 410 hits the rubber roller 48 provided at the bottom end of the curved plate 47, so that the rubber roller 48 drives the curved plate 47 to start rotating, so that the top end of the curved plate 47 rotates toward the side close to the bottle cork piercer 3 with the limit rod 44 as the axis, and then the outer wall of the bottle cork piercer 3 is hit by the rubber roller 48 provided on the top of the special-shaped block 45, so that the bottle cork piercer 3 is always on the same horizontal plane with the infusion hose 2 during the placement process, thereby achieving the positioning effect, and also achieving the effect of preliminary clamping and fixing.

[0061] During the assembly process of the bottle stopper piercer 3 and the infusion hose 2, steps for ensuring that the bottle stopper piercer 3 and the infusion hose 2 can be effectively assembled are as follows:

[0062] like Figures 3 to 5 As shown, after the personnel places the infusion hose 2 on the top of the loading plate 53 and the support platform 52, the cover plate 512 is controlled by the external control device to slide on the top of the mounting platform 1 toward the side close to the bottle cork puncture device 3, so that the inclined surface 3 provided on the cover plate 512 conflicts with the inclined surface 2 provided on the outer section of the clamping block 57, so that the clamping block 57 moves toward the side close to the infusion hose 2 under the conflicting action of the cover plate 512, and then the clamping block 57 drives the hinged plate 56 to flip toward the side close to the infusion hose 2 with the fixed rod 54 as the axis, and then the hinged plate 56 drives the torsion spring 55 to start rotating synchronously. During the movement of the clamping block 57, the rubber plate 1 511 is driven to clamp the outer wall of the infusion hose 2 first, and then the clamping block 57 continues to move, which will cause the rubber plate 1 511 to rotate synchronously. 11 drives the slide bar 59 to move inside the fixed plate 58 toward the side away from the infusion hose 2, thereby causing the slide bar 59 to drive the spring 510 to extend toward the side away from the rubber plate 511, thereby causing the rubber plate 511 to elastically clamp the outer wall of the infusion hose 2, until the clamping block 57 clamps the outer wall of the infusion hose 2, the end of the bottle stopper 3 close to the infusion hose 2 has been inserted into the interior of the bottle stopper piercer 3, and the part clamped by the rubber plate 511 is at the position where the bottle stopper piercer 3 has been inserted into the interior of the infusion hose 2, thereby making the part where the bottle stopper piercer 3 has been inserted into the interior of the infusion hose 2 fit tightly, until the bottle stopper piercer 3 is completely inserted into the interior of the infusion hose 2, at which time the cover plate 512 no longer moves.

[0063] It is used to protect the bottle stopper puncture device 3 and the infusion hose 2 during the assembly process to prevent them from being contaminated by bacteria in the environment. Steps:

[0064] like Figures 6 to 8As shown, during the entire process of the cover plate 512 moving toward the side close to the bottle cork piercer 3, the cover plate 512 drives the rectangular tooth plate 63 to move synchronously toward the side close to the bottle cork piercer 3, so that the rectangular tooth plate 63 drives the gear rod 62 meshing therewith to rotate inside the fixed plate 2 61, so that the gear rod 62 drives the diagonal rod 64 to rotate synchronously, so that the oblique groove provided inside the diagonal rod 64 contacts the slider 68, so that the slider 68 slides in the oblique groove of the diagonal rod 64, and then the slider 68 drives the circular ring plate 67 to slide toward the side close to the bottle cork piercer 3, so that the circular ring plate 67 drives the slide plate 66 to move synchronously, and then the slide plate 66 drives the rubber plate 2 69 to clamp the outer wall of the non-connected part of the bottle cork piercer 3 during the sliding process inside the limiting groove 65, thereby realizing the bottle cork piercer 3. The secondary clamping effect is achieved. At the same time, during the movement of the slide plate 66, the slide plate 66 drives the first bracket 610 to move synchronously, so that the first bracket 610 drives the alcohol nozzle 611 to move to the side close to the bottle cork piercer 3, thereby causing the two alcohol nozzles 611 to converge. During the convergence of the alcohol nozzles 611, the electrical block 612 enters the interior of the electrical slot 613, and then the alcohol nozzle 611 is controlled by an external control device to spray alcohol toward the center position. During the assembly of the bottle cork piercer 3 and the infusion hose 2, a disinfection effect is achieved, and dust and hair are prevented from adhering to the connection between the bottle cork piercer 3 and the infusion hose 2. At the same time, the synchronous effect of assembly and disinfection of the infusion hose 2 and the bottle cork piercer 3 is achieved, thereby ensuring the safety of the disposable infusion set.

[0065] When the infusion hose 2 and the bottle cork piercer 3 are assembled, the personnel controls the cover plate 512 to move to the side away from the bottle cork piercer 3 through an external device, so that the cover plate 512 drives the rectangular tooth plate 63 to move synchronously, and then the rectangular tooth plate 63 drives the gear rod 62 to rotate in the opposite direction inside the fixed plate 2 61, and then the gear rod 62 drives the diagonal rod 64 to rotate in the opposite direction synchronously, so that the diagonal rod 64 drives the circular plate 67 to move in the opposite direction through the slider 68, and then the rubber plate 2 69 no longer squeezes the bottle cork piercer 3, and at the same time separates the two alcohol nozzles 611, so that the alcohol nozzle 611 no longer sprays alcohol on the connection between the bottle cork piercer 3 and the infusion hose 2.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
