Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a segmented timing dip-type dispensing device. Background Technology

[0002] In the medical industry, tubing dispensing is a common process, primarily used in the assembly of components such as catheters, infusion tubing, and endoscopic tubing in medical devices. It aims to reliably secure flexible or semi-rigid medical tubing to connectors, housings, or other critical structures. This dispensing process demands extremely high biocompatibility and precision, typically using medical-grade epoxy, silicone, or UV adhesives to ensure the adhesive is non-toxic, produces no leaching after curing, and provides a strong bond without interfering with fluid flow. This technology is widely used in urinary catheters, vascular interventional devices, and minimally invasive surgical equipment, serving as a crucial step in ensuring the safety and stability of medical devices.

[0003] Currently, most medical devices use dipping or semi-automatic dispensing methods for dispensing adhesive into tubing. However, these methods usually cannot distinguish between dispensing adhesive into the outer and inner walls of the tubing. In particular, adhesive residue often remains on the inner wall of the tubing and cannot be completely cleaned, which can lead to biological risks to the product. In addition, these dispensing methods cannot control the dispensing time or the curing time of the adhesive during the dispensing process.

[0004] Therefore, there is an urgent need for a segmented timing dip-type dispensing device that can overcome the above-mentioned defects. Utility Model Content

Figure 2 The diagram shows the structure of the dispensing module 1. The segmented timing dip-type dispensing device includes: a dispensing module 1, which includes a dispensing sleeve 3 and a dispensing needle 4; the dispensing sleeve 3 contains glue and is used to dispense glue onto the tubing; the dispensing needle 4 is disposed inside the dispensing sleeve 3 by an elastic element, and is squeezed to a fixed position at the start of dispensing and returns to its original position after dispensing; and a timing module 2, which controls the dispensing time of the tubing when the dispensing needle 4 is squeezed to the fixed position and controls the curing time of the tubing when the dispensing needle 4 returns to its original position.

[0033] Optionally, the dispensing module 1 further includes an overflow groove 5; the overflow groove 5 is connected to the dispensing sleeve 3, and the height of the overflow groove 5 is lower than the height of the dispensing sleeve 3.

[0034] Optionally, the dispensing module 1 further includes an overflow storage tank 6; the overflow storage tank 6 is disposed below the overflow tank 5, and the overflow storage tank 6 is used to store the glue overflowing from the overflow tank 5.

[0035] Optionally, the dispensing module 1 further includes a pressure sensor 7; the pressure sensor 7 is disposed at the end of the dispensing needle 4 away from the tubing; the pressure sensor 7 is used to trigger the dispensing countdown of the timing module 2 when the dispensing needle 4 is squeezed to a fixed position, and to trigger the curing countdown of the timing module 2 when the dispensing needle 4 returns to its original position.

[0036] Optionally, the segmented timing dip-type dispensing device further includes an adhesive filling module; the adhesive filling module is connected to the dispensing sleeve 3, and the adhesive filling module is used to replenish adhesive into the dispensing sleeve 3.

[0037] Optionally, the glue filling module includes a glue storage tank 8 and a glue guide tube 9; the glue storage tank 8 is used to store spare glue, and the glue storage tank 8 is connected to the glue dispensing sleeve 3 through the glue guide tube 9.

[0038] Optionally, the height of the glue storage tank 8 is greater than the height of the glue application sleeve 3.

[0039] Optionally, the segmented timing dip-type dispensing device further includes a protective cover 10; the protective cover 10 covers the dispensing module 1.

[0040] Optionally, the protective cover 10 plate is connected to the dispensing module 1 via a magnetic chuck 11.

[0041] Optionally, the protective cover 10 is provided with a first opening and a second opening; the position of the first opening corresponds to the position of the dispensing sleeve 3, and the diameter of the first opening is equal to the diameter of the dispensing sleeve 3; the position of the second opening corresponds to the position of the adhesive guide tube 9 at the connection point on the dispensing module 1, and the second opening is used to allow the adhesive guide tube 9 to pass through the second opening and connect to the dispensing module 1.

[0042] For example, the working principle of the above-mentioned segmented timing dip-type dispensing device is explained using a single pipeline dispensing process as an example: Adhesive is added to the adhesive storage tank 8, and the adhesive in the adhesive storage tank 8 flows into the dispensing sleeve 3 through the adhesive guide tube 9. At this time, the worker can immerse the pipeline into the dispensing sleeve 3, at which point the pipeline will squeeze the dispensing needle 4, and the pressure will be transmitted to the pressure sensor 7 through the dispensing needle 4. The pressure sensor 7 is connected to the timing module 2, and the timing module 2 can determine that dispensing has started. The timing module 2 immediately starts the dispensing countdown. After the countdown ends, the dispensing ends, and the worker removes the pipeline from the dispensing sleeve 3. At this time, the pipeline stops squeezing the dispensing needle 4, and the dispensing needle 4 returns to its original position. The pressure sensor 7 detects that the dispensing needle 4 has returned to its original position, and the timing module 2 can determine that curing has started, and immediately starts the curing countdown. After the countdown ends, the pipeline has been cured. During the dispensing of adhesive onto the pipe, to prevent the adhesive from overflowing from the dispensing sleeve 3 after the pipe is immersed in it, an overflow groove 5, lower in height than the dispensing sleeve 3, is specially designed. Since the overflow groove 5 is connected to the dispensing sleeve 3, excess adhesive overflows from the overflow groove 5 instead of from the dispensing sleeve 3. Furthermore, an overflow storage groove 6 is provided below the overflow groove 5 to store the adhesive overflowing from it, allowing for recycling. In addition, the protective cover 10 protects the dispensing module 1 from external contamination. The connection between the protective cover 10 and the dispensing module 1 via the magnetic connector 11 also increases the detachability of the protective cover 10, facilitating maintenance of the dispensing module 1.

[0043] Optionally, the dispensing needle 4 can be replaced with different types of dispensing needles 4 to meet different dispensing needs, such as dispensing inside the pipeline or dispensing outside the pipeline.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
