Description

Technical Field

[0001] The present application relates to the technical field of marking tubes, and in particular to a PTFE marking tube. Background Art

[0002] In the medical field, marking tubes are often used to identify and distinguish different medical devices, catheters, circuits, etc. They can help medical staff quickly and accurately identify various devices and circuits to ensure safety and efficiency during surgery or diagnosis and treatment.

[0003] In order to facilitate users to distinguish the medical equipment, catheters, lines, etc. corresponding to each color of ink before use, a marking tube made of PTFE is often used. The marking tube is provided with a strip-shaped color portion along its length. The color portion is formed by adding a colored blank to the original PTFE blank and extruding the blank. The formed marking tube is extruded and integrally formed with a strip-shaped and colored portion along its length.

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] The embodiment of the present application discloses a PTFE marking tube.

[0031] Reference Figure 1 and Figure 2 A PTFE marking tube includes a sleeve 1 made of PTFE. The sleeve 1 is provided with a plurality of embedding grooves 12 at intervals in the circumferential direction. The embedding grooves 12 are opened along the length direction of the sleeve 1. The sleeve 1 is provided with colored strips 2 of different colors at intervals in the circumferential direction. The colored strips 2 are embedded in the embedding grooves 12 and form an interference fit with the sleeve 1. The colored strips 2 are fixed to the sleeve 1 through the interference fit between the colored strips 2 and the embedding grooves 12. The colored strips 2 embedded in the embedding grooves 12 can be replaced to improve the practical flexibility of the marking tube.

[0032] Reference Figure 1 , both ends of the sleeve 1 in the length direction are provided with guiding inclined surfaces 11. The guiding inclined surfaces 11 provided at both ends of the sleeve 1 in the length direction are utilized to facilitate the plugging and installation operation at both ends of the sleeve 1 in the length direction.

[0033] Reference Figure 1 and Figure 2The sleeve 1 is rotatably connected to a rotating ring 3, and an indicator ring 4 is rotatably provided on the sleeve 1. The indicator ring 4 is provided with an indicator port 41 that matches the colored strip 2. The outer ring surface of the rotating ring 3 is provided with a movable groove 31 along the length direction of the sleeve 1, and the inner ring surface of the indicator ring 4 is provided with a movable block 42 located in the movable groove 31. The indicator ring 4 is moved along the length direction of the sleeve 1 by the movable block 42 located in the movable groove 31. When the indicator ring 4 is located outside the rotating ring 3, the portion of the sleeve 1 with the colored strip 2 is not blocked by the indicator ring 4, making it convenient to replace the colored strip 2. When the marking tube is located at the portion of the colored strip 2 of the sleeve 1, the indicator ring 4 on the sleeve 1 is rotated, and the colored strip 2 to be marked according to the marking tube is displayed through the indicator port 41 on the indicator ring 4, making it convenient for the user to observe and use the marking tube, thereby improving the flexibility of the marking tube.

[0034] Furthermore, a first magnetic block is provided on the side of the movable groove 31 near the colored stripe 2, and a second magnetic block is provided on the movable block 42 to cooperate with the first magnetic block. When the indicator ring 4 moves to the portion of the sleeve 1 where the colored stripe 2 is located, the first and second magnetic blocks cooperate to improve the stability of the indicator ring 4 on the sleeve 1.

[0035] Reference Figure 1 The outer wall of indicator ring 4 is provided with a wear-resistant layer. The wear-resistant layer provided on the outer wall of indicator ring 4 helps to increase the service life of indicator ring 4. The outer wall of indicator ring 4 is provided with anti-slip grooves 43. The anti-slip grooves 43 provided on the outer wall of indicator ring 4 make it easier for the user to rotate indicator ring 4.

[0036] Furthermore, a fluorescent layer is provided on the color strip, which makes it easier for users to distinguish the marking tube when the light line is not good.

[0037] The implementation principle of a PTFE marking tube in an embodiment of the present application is as follows: the indicator ring 4 is moved along the length direction of the sleeve 1 by a moving block 42 located in the moving groove 31. When the indicator ring 4 is located outside the rotating ring 3, there is no indicator ring 4 outside the colored strip 2 part of the sleeve 1 to block it. The colored strip 2 and the embedding groove 12 are interfered with to achieve a card-fit fixation with the sleeve 1, which facilitates the replacement of the colored strip 2 embedded in the embedding groove 12. When the marking tube is located at the colored strip 2 part of the sleeve 1, the indicator ring 4 on the sleeve 1 is rotated, and the colored strip 2 to be marked according to the marking tube is displayed through the indicator port 41 on the indicator ring 4, which facilitates the user to observe and use the marking tube and improves the flexibility of using the marking tube.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
