Description

Technical Field

[0001] This utility model relates to the field of catheter manufacturing technology, and in particular to an automatic cutting device for anesthesia catheters. Background Technology

[0002] Anesthesia catheters are essential consumables in clinical anesthesia. Their main function is to continuously and accurately deliver local anesthetic solutions to the target nerves to achieve long-lasting analgesia. Existing anesthesia catheters are mainly made of medical-grade flexible polymer materials and are generally long and hollow.

[0003] Existing anesthesia catheters are mainly made of polyurethane and silicone during the manufacturing process. Because the overall length of the catheter is relatively long after production, it is necessary to transport the catheter by coiling it for easy delivery. Therefore, the catheter needs to be cut to meet the required size.

[0004] The existing cutting method mainly uses manual cutting. Manual cutting is difficult to guarantee cutting efficiency, which affects production efficiency. Furthermore, it is impossible to guarantee dimensional accuracy during the cutting process, which affects production quality. If the cut cannot be made evenly, it can lead to the needle of the connecting tube falling off and large gaps at the connection point, and it can also cause leakage of anesthetic liquid, affecting its use.

[0005] Therefore, how to automate the cutting of anesthesia catheters is a major technical problem that technicians need to solve. Utility Model Content

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The following is in conjunction with the appendix Figures 1 to 5 The technical solutions of the embodiments of this utility model are described in detail.

[0029] Example 1: To automate the cutting of anesthesia catheters, existing anesthesia catheters, after forming, have a certain length and need to be cut to segment them to meet the required length specifications. Furthermore, manual cutting of existing catheters is inefficient and affects production efficiency. This example includes a support base plate 1, a feeding assembly 2, a support assembly 3, and a strip cutter 4. The feeding assembly 2 and support assembly 3 are both mounted on the support base plate 1. The support assembly 3 includes two parallel support columns 31. The strip cutter 4 is horizontally mounted on the support assembly 3, and both ends of the strip cutter 4 are fixed to the two support columns 31. A pressing cylinder 32 is also mounted on the support assembly 3, with its power output end connected to a pressing plate 33. The lower surface of the pressing plate 33 corresponds to the blade of the strip cutter 4, forming a cutting station for segmented cutting of the anesthesia catheter as it passes through.

[0030] It should be noted that the feeding assembly 2 includes a conveyor belt 21 and a driven rotating shaft 22. The conveyor belt 21 is sleeved on the outside of the driven rotating shaft 22 and is used to convey the anesthesia catheter to be cut. One end of the conveyor belt 21 is aligned with the support assembly 3. A guide plate 5 is provided between the support assembly 3 and the feeding assembly 2. A circular through hole 51 is provided at the center of the guide plate 5 so as to guide the anesthesia catheter to enter the cutting station in a straight state.

[0031] Based on the above structure, a detailed description is provided. During operation, the anesthesia catheter is conveyed by the conveyor belt 21, passes through the circular through hole 51 of the guide plate 5, and reaches above the strip cutter 4. The pressing cylinder 32 drives the pressing plate 33 to move downward, cooperating with the strip cutter 4 to complete the cutting action. The entire cutting action is automated and requires no manual intervention, which significantly improves cutting efficiency and consistency and is suitable for continuous production.

[0032] Example 2: To further improve cutting accuracy and stability, ensure even cuts, and prevent displacement or deformation of the conduit during cutting, since existing conduits will have uneven cuts and affect cutting size accuracy if they are displaced during cutting, this example: guide kits 41 are provided at both ends of the strip cutter 4, and guide columns 331 are provided at both ends of the pressing plate 33. When the pressing plate 33 moves downward toward the strip cutter 4, the guide columns 331 can slide within the guide kits 41, and the guide columns 331 and the guide kits 41 form a guide structure to ensure that the pressing plate 33 remains stable during up and down movement, avoids positional deviation, and thus ensures that the cutting force is evenly applied to the conduit.

[0033] A sensor body (not shown in the figure) is provided on the guide plate 5, with its detection port facing the outlet side of the circular through hole 51. The sensor body can be an OMRON EE-SX671 photoelectric sensor or an equivalent fiber optic sensor. The working principle is as follows: when the end of the anesthesia catheter passes through the circular through hole 51 and reaches the preset cutting position of the cutting station, the sensor will send a positioning signal when the light path of the sensor is blocked. The signal is transmitted to the control system of the device (such as a PLC or microcontroller). The control system then issues an instruction to first stop the drive motor 11 so that the feeding component 2 stops feeding, and then start the pressing cylinder 32 to drive the pressing plate 33 to press down on the blade of the strip cutter 4, performing a cutting action on the anesthesia catheter between the pressing plate 33 and the strip cutter 4. This closed-loop control logic ensures the accuracy of the cutting timing and achieves a fixed-length cutting effect.

[0034] In this embodiment, it should be added that the bottom of the support component 3 is detachably provided with a mounting base 34 by bolts. The mounting base 34 has a slot for mounting the strip cutter 4. The detachable design facilitates the replacement and maintenance of the strip cutter 4 and reduces the operating cost of the equipment.

[0035] In addition, it should be added that the side of the pressing plate 33 opposite to the strip cutter 4 can be processed to form a flat cutting plane. The cutting plane can also be perpendicular to the central axis of the circular through hole 51 on the guide plate 5. This design ensures that the anesthesia catheter is evenly compressed and the force is stable during cutting, thereby obtaining a flat, burr-free cut. It effectively avoids the problem of oblique cutting or the lumen tilting and deforming due to unstable cutting force, and meets the high requirements of anesthesia catheter for cut quality.

[0036] In particular, this embodiment further optimizes the precision, reliability, and maintainability of the cutting process by introducing a precise guiding structure, sensitive photoelectric sensing control, and a detachable modular design, making it especially suitable for high-standard automated production processes of anesthesia catheters.

Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the structure in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
