Description

Technical Field

[0002] In the modern medical system, medical instruments play a key role. However, due to their complex usage scenarios, they are often exposed to various chemical reagents and are subjected to temperature changes and pressure shocks, which makes the instruments prone to leakage. This will not only cause sample contamination and deviation in test results, but may also delay diagnosis and treatment, posing potential risks to patients.

[0015] Compared with the prior art, the present invention provides a medical vessel leakage detection device, which has the following beneficial effects: 1. The present invention provides a medical vessel leakage detection device. When an optical detector is used to perform leakage detection on a medical vessel, the medical vessel can be clamped and fixed with the help of an adjustment mechanism, and can also be rotated and adjusted at different angles.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limitations on the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0024] Example 1: See Figure 1-Figure 5 The present invention provides a technical solution: a medical vessel leakage detection device, comprising a detection mechanism 1, the detection mechanism 1 comprising a support frame 101, the inner wall of the support frame 101 is fixedly connected with a detection frame 102, the inner wall of the detection frame 102 is fixedly connected with an optical detector 103, the outer wall of one end of the support frame 101 close to the optical detector 103 is fixedly connected with a fixing ring 104, and the top outer surface of the fixing ring 104 is provided with a groove 105, including: The adjustment mechanism 2 includes a sliding frame 201 slidably connected to the fixed ring 104, a first auxiliary motor 202 is fixedly connected to the top outer wall of the sliding frame 201, an output end of the first auxiliary motor 202 passes through the sliding frame 201 and is fixedly connected to a driving wheel 203, an outer surface of the driving wheel 203 is rollingly connected to the inner wall of the groove 105, a first telescopic rod 204 is fixedly connected to the inner wall of the sliding frame 201, and an output end of the first telescopic rod 204 is fixedly connected to a first connecting frame 209. When the medical vessel is ready to be leak tested, the first telescopic rod 204 will adjust the distance between the first connecting frames 209 according to the actual thickness of the medical vessel so as to adapt to vessels of different thicknesses so that they can be firmly fixed. After the medical vessel is successfully clamped and fixed, the first auxiliary motor 202 drives the sliding frame 201 to slide along the outer surface of the fixed ring 104 through the driving wheel 203. During this process, the optical detector 103 performs comprehensive and uniform light irradiation on the outer surface of the medical vessel.

[0025] The inner wall of the first connecting frame 209 is rotatably connected to the rotating rod 206 through a rotating shaft, and the end of the rotating rod 206 away from the first connecting frame 209 is rotatably connected to the sliding block 207 through the rotating shaft, the inner wall of the sliding frame 201 is fixedly connected to the fixed shaft 205, and the sliding block 207 is slidably connected to the outer surface of the fixed shaft 205. The outer wall of the end of the sliding block 207 away from the rotating rod 206 is fixedly connected to the first spring 208, and the end of the first spring 208 away from the sliding block 207 is fixedly connected to the sliding frame 201. In the preparation stage before leakage detection for medical vessels, when the first telescopic rod 204 adjusts the first connecting frame 209 according to the thickness of the measured medical vessel, the first connecting frame 209 pushes the sliding block 207 to slide on the outer surface of the fixed shaft 205 with the help of the rotating rod 206, thereby ensuring that the sliding distances of the first connecting frames 209 on both sides of the first telescopic rod 204 remain consistent.

[0026] Example 2: See Figure 6-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the inner wall of the first connecting frame 209 is fixedly connected with a second telescopic rod 210, the output end of the second telescopic rod 210 is fixedly connected with a second connecting frame 211, the outer wall of the second connecting frame 211 away from the second telescopic rod 210 is fixedly connected with a second auxiliary motor 215, the output end of the second auxiliary motor 215 passes through the second connecting frame 211 and is fixedly connected with a first fixing frame 216, when preparing to perform a clamping operation on the medical vessel, the second telescopic rod 210 will automatically adjust accordingly according to the actual diameter of the medical vessel to ensure that the vessel can be firmly clamped, and the second auxiliary motor 215 drives the medical vessel to flip the angle through the first fixing frame 216, so that the optical detector 103 can perform leakage detection on the medical vessel from multiple different angles, which greatly improves the comprehensiveness and accuracy of the detection.

[0027] The outer wall of one side of the second connecting frame 211 close to the second telescopic rod 210 is fixedly connected with a connecting shaft 212, and the end of the connecting shaft 212 away from the second connecting frame 211 passes through the first connecting frame 209 and is fixedly connected with a limiting block 213. The limiting block 213 is used to limit the sliding distance of the second connecting frame 211. The inner wall of the limiting block 213 is slidably connected to the outer wall of the second telescopic rod 210, and the top outer wall of the limiting block 213 is fixedly connected with a second spring 214. The end of the second spring 214 away from the limiting block 213 is fixedly connected to the first connecting frame 209. A connecting frame 209 is fixedly connected. When the medical vessel clamping operation is performed, the second telescopic rod 210 pushes the second connecting frame 211 to move toward the medical vessel, and the second connecting frame 211 drives the limit block 213 to slide toward the side of the medical vessel via the connecting shaft 212, and then the limit block 213 exerts an extrusion effect on the second spring 214. The second connecting frame 211 forms a sliding connection with the inner wall of the first connecting frame 209 through the connecting shaft 212, thereby effectively enhancing the stability of the second connecting frame 211 during movement.

[0028] The inner wall of the first fixed frame 216 is fixedly connected with a hydraulic rod 217, the output end of the hydraulic rod 217 passes through the first fixed frame 216 and is fixedly connected with a clamping rod 218, the inner wall of the clamping rod 218 is rotatably connected with a ball 219, the ball 219 is used to assist the medical vessel in rotating, and the ball 219 is set to a rubber material to avoid damage to the glass medical vessel, the outer surface of the hydraulic rod 217 is fixedly sleeved with a second fixed frame 220, the outer wall of the second fixed frame 220 is fixedly connected with a driving motor 221, the output end of the driving motor 221 passes through the second fixed frame 220 and is fixedly connected with a driving roller 222, The inner wall of the driving roller 222 is fixedly connected with an elastic component 223. When the medical vessel is to be leak tested and its angle needs to be adjusted, the driving motor 221 drives the medical vessel through the driving roller 222. The elastic component 223 on the driving roller 222 is deformed after contacting the outer surface of the medical vessel. This deformation can increase the contact area between the elastic component 223 and the medical vessel, allowing the driving roller 222 to better drive the vessel to rotate. The hydraulic rod 217 pushes the clamping rod 218 to approach the medical vessel. The ball 219 on the inner wall of the clamping rod 218 rotates when contacting the vessel, which can not only firmly clamp the medical vessel, but also reduce damage to the vessel.
