Abstract
Description
Technical Field
[0001] This application relates to the technical field of etching medical needle tubes, and in particular to an etching device for scale lines on medical needle tubes. Background Technology
[0002] In the medical field, medical needles are widely used medical devices, and their accurate information collection is crucial for medical safety and quality control. Medical needles are ubiquitous in medical settings, playing a key role in everything from routine injections and infusions to complex surgical procedures. For example, in vaccination, accurate needle specifications and drug dosages are essential to ensuring immunization effectiveness; in the operating room, precise injection of anesthetic drugs requires reliable needles; and in intensive care units, the correct use of needles is indispensable for the infusion of various medications. Medical puncture needles, in particular, need to have graduations on their surface so that medical staff can accurately determine the puncture depth when performing punctures on patients.
[0003] In the existing technology, the scale lines of medical needle tubes are etched by electrolyte. The upper electrode plate of the etching device is connected to the positive terminal of the power supply and presses down on the steel tube, which acts as the anode. The conductive cloth and the lower electrode plate are connected to the negative terminal of the power supply to form the cathode. The upper electrode plate presses down on the steel tube and rolls on the conductive cloth. The etching is completed by corroding the steel tube through the film output structure of the conductive cloth.
[0004] However, in the existing technology, the pressure of the upper electrode plate on the needle tube is unstable during the rolling process of pressing the needle tube, resulting in uneven etching, which cannot meet the needs of medical applications. Utility Model Content

[0015] In some alternative implementations, the etching stage is connected to the negative electrode and the electrode cap assembly is connected to the positive electrode, forming an electrical path consisting of the etching stage, conductive cloth, needle and electrode cap assembly.
[0016] In some alternative implementations, the adjustment hole is waist-shaped.
[0017] In some alternative embodiments, limiting grooves are also provided on opposite sides of the outer shell, and the setting direction of the limiting grooves is perpendicular to the extension direction of the needle tube.

[0020] The medical syringe scale etching device provided in this application has the following beneficial effects:

The conductive cloth is in close contact with the inner wall of the etching holes, and the etching stage can be moved at any time under the interaction of the adjustment hole, the adjustment rod and the locking head. Under the action of the motor cap device, an electrical path is formed consisting of the etching stage, the conductive cloth, the needle tube and the electrode cap assembly. This enables uniform etching during the etching process and allows for adjustment according to the etching position, effectively improving the ease of operation and etching effect.

Figure 6 This is a perspective view of the electrode cap assembly in a medical needle scale line etching device according to this application.

[0042] To facilitate understanding, the working principle of this application is further described as follows: In the medical needle scale line etching device, during operation, firstly, according to the required etched scale line position of the needle, the locking head 25 is loosened to move each etching stage 22. Simultaneously, the adjusting rod 23 moves along the direction of the adjusting hole 11. A measuring tape is used to determine the moving distance, and after the etching stage 22 is moved to the required position, the locking head 25 fixes the position of each etching stage 22. Then, a needle sequentially passes through the axially identical etching holes 26 of different etching stages 22. Each needle passes through each etching stage 22 separately. After the tube passes through the etching stage 22 and through the etching hole 26, the outer wall of the tube is tightly fitted with the conductive cloth 27 inside the etching hole 26. Then, the electrode cap assembly 31 is put on the tube near the electrode cap device 30. Finally, the power supply is turned on according to the positive and negative charges, and the electrolyte is connected. After a specified time, the etching of the tube is completed. During the etching process, there is no need to use the upper electrode plate to press the tube and make the tube roll for etching. This effectively avoids the uneven etching caused by unstable pressure, and achieves uniform etching during the etching process, which effectively improves the etching effect.
