Description

Technical Field

[0001] The utility model relates to the technical field of medical device processing equipment, in particular to a medical balloon eccentricity testing device. Background Art

[0002] Many medical devices need to use balloons, such as medical catheter balloons, medical lobed balloons, medical dilation balloons, balloon puncture devices, etc., which are widely used. Considering the different usage scenarios and methods of different medical devices, in some devices, the balloons are required to be arranged centrally, while in some balloons, eccentric arrangement is required. Therefore, for the production and processing process of the devices, precise position control of the balloons is needed, and thus corresponding detection and debugging devices are required to control the position of the balloons on the relevant devices.

[0003] In the prior art, the device that can currently measure the eccentricity of a balloon is a coordinate measuring machine. The coordinate values of the detected points of the balloon are read and displayed by a probe to obtain the eccentricity of the balloon. However, the actual detection process of the balloon is very inconvenient. The coordinate measuring machine is a precision detection device that requires a dedicated place for placement and professional personnel to operate and maintain it. The coordinate measuring machine takes a long time to detect a single balloon, with low detection efficiency, and has high requirements for the professionalism of the detection personnel, and is not suitable for batch detection of balloons.

[0004] In summary, aiming at the problems of cumbersome operation and low detection efficiency of the existing devices for balloon eccentricity testing, a fast and efficient detection device needs to be designed. Content of the Utility Model

[0011] The connection line of the pair of slides is perpendicular to the connection line of the pair of bases.

[0012] In an alternative embodiment of the present utility model, each base is slidably engaged with the workbench surface through a guide rail.

[0029] In order to make the content of the present utility model easier to be clearly understood, the following further details the present utility model according to specific embodiments in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1 to 4 As shown, this embodiment provides a medical balloon eccentricity testing device, which is particularly suitable for measuring the eccentricity of the balloon 100 in the catheter balloon. Specifically, its general structure includes: a test base 300 and a balloon positioning assembly and a measuring sliding table assembly provided on the test base 300, wherein the test base 300 has a working surface.

[0031] Next, specifically, regarding the balloon positioning assembly:

[0032] Generally, it includes a pair of bases 1 that are adapted to position the balloon 100 from both axial ends of the balloon 100 and are slidably engaged with the working surface. Each of the bases 1 here is slidably engaged with the working surface through a guide rail 2.

[0033] Based on the above situation, the pair of bases 1 can slide relative to the working surface to adjust the distance between the pair of bases 1. The function of such a design is as follows:

[0034] First, by adjusting the distance between the pair of bases 1, the medical balloon eccentricity testing device of this embodiment can be applicable to a large range of specification sizes of the balloon 100, thereby improving the applicability of the overall testing device to different balloons 100.

[0035] Second, when a pair of bases 1 need to achieve positioning of the balloon 100 by clamping the balloon 100, the clamping and release of the balloon 100 can be achieved by adjusting the distance between the pair of bases 1. In this process, it should be noted that there is a certain friction between the mating surfaces between the base 1 and the guide rail 2, and a certain pulling force needs to be applied to the base 1 to make the base 1 move on the guide rail 2. Of course, the pulling force here does not need to be too large, and it only needs to prevent the base 1 and the guide rail 2 from sliding relative to each other. In this way, through the friction design, there is no need to design a locking structure between the base 1 and the guide rail 2 to maintain the stability of the position of the pair of bases 1 on the guide rail 2 when the pair of bases 1 position the balloon 100.

[0036] Based on the above situation, in an optional implementation, a pair of bases 1 can limit the radial dimension of the balloon 100 by clamping the balloon 100 so that it does not produce radial shaking.

[0037] Furthermore, in an optional implementation, in order to facilitate the positioning of the balloon 100, a positioning groove 11 is provided on the top of each base 1 for embedding the catheter 200 connected to the balloon 100. The positioning groove 11 here can be optionally a V-shaped groove, so that the catheter 200 will not shake in the positioning groove 11. In this way, even if the balloon 100 is not clamped by a pair of bases 1, the balloon 100 will not shake in the radial direction of the catheter 200, thereby ensuring the reliability of the eccentricity test process of the balloon 100.

[0038] On the basis of the above structure, in order to reduce the damage to the outer surface of the balloon 100 caused by the base 1 when positioning the balloon 100, the present embodiment optionally provides a flexible pad 3 on the end face of each base 1 for positioning the balloon 100, and the flexible pad 3 is made of, for example but not limited to, a silicone pad.

[0039] Next, let’s talk about the measurement slide assembly:

[0040] Generally speaking, it includes a pair of slides 4 suitable for respectively abutting against a pair of opposite side end surfaces of the balloon 100 and slidingly cooperating with the work surface, and a pair of rulers 5 arranged one-to-one with the pair of slides 4; it should be noted that the connecting line of the pair of slides 4 and the connecting line of the pair of bases 1 are perpendicular to each other.

[0041] It should also be noted that, in order to protect the outer surface of the balloon 100 and prevent the outer surface of the balloon 100 from being worn during the test, the present embodiment also has the following designs:

[0042] A clamping plate 6 for abutting against the balloon 100 is provided on each sliding table 4. The side end face of the clamping plate 6 facing the balloon 100 protrudes from the side end face of the sliding table 4 facing the balloon 100. The side end face of the clamping plate 6 for abutting against the balloon 100 is a flat straight face. A flexible pad 8 is provided on the side end face of the clamping plate 6 for abutting against the balloon 100.

[0043] More specifically, each sliding table 4 is slidably engaged with the workbench surface through a slide rail 7. In this structure, that is to say, the guide rail 2 and the slide rail 7 are orthogonally distributed. This structure ensures the accuracy of the eccentric test results of the balloon 100. It should be noted that there is a certain friction between the mating surfaces of the sliding table 4 and the slide rail 7. A certain pulling force needs to be applied to the sliding table 4 to make the base 1 move on the slide rail 7. Of course, the pulling force here does not need to be too large, as long as it can prevent relative sliding between the sliding table 4 and the slide rail 7. In this way, through the design of friction, there is no need to design a locking structure between the sliding table 4 and the slide rail 7 to maintain the stability of the position of the pair of sliding tables 4 on the slide rail 7 when the clamping plates 6 on the pair of sliding tables 4 abut against the outer surface of the balloon 100.

[0044] On the basis of the above structure, it should also be noted that each scale 5 is fixed on the workbench surface; and scale lines 51 are designed on each scale 5; each scale 5 is perpendicular to the connection line of the pair of bases 1.

[0045] In summary, for the medical balloon eccentric test device of this embodiment, the balloon 100 fixed on the catheter 200 is clamped through the balloon positioning assembly, so that the balloon 100 will not shake during the test. Based on this situation, by adjusting the relative distance between the pair of sliding tables 4, when the clamping plate 6 on the sliding table 4 abuts against the balloon 100, the position of the sliding table 4 can be accurately known through the scale line 51 on the scale 5 to obtain the specific eccentricity of the balloon 100. The overall operation process only needs to move the pair of bases 1 and the pair of sliding tables 4, which is convenient and efficient. Even non-professional testers can do it, and the operation threshold is low.
