Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of medical device cleaning technology, and more specifically, to a sample rinsing device for detecting particulate matter in medical devices. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, etc., that are used directly or indirectly on the human body. Their effects are mainly achieved through physical and mechanical means, rather than pharmacological, immunological, or metabolic methods. In order to ensure the safety and effectiveness of the devices and avoid the harm to human health or device function caused by particulate contamination, it is necessary to conduct particulate detection on medical devices. In the particulate detection of medical devices, rinsing the sample to be tested is a key step in obtaining an effective test sample. Its purpose is to transfer the particulates attached to the surface or inside of the device into the rinsing solution so that they can be quantitatively analyzed by methods such as microscopic counting and laser particle counting.

[0003] Currently, particle detection flushing devices for medical devices typically clean the exterior of the devices. However, the inner walls of some catheter-type medical devices are difficult to flush evenly, which can lead to poor flushing results and consequently affect the particle detection performance of these devices.

[0027] like Figures 1-4As shown, this embodiment illustrates a sample rinsing device for particle detection in medical devices, comprising a rinsing chamber 1, and further comprising: a support 2, a rotating plate 3, a delivery pipe 4, an adjustment mechanism, and a delivery mechanism. The support 2 is fixedly connected inside the rinsing chamber 1, and a rotating opening is provided on the support 2. The rotating plate 3 is disposed inside the rotating opening via the rotating mechanism. The delivery pipe 4 is rotatably connected to the rotating plate 3, and a rinsing mechanism is provided at the top end of the delivery pipe 4. The rinsing mechanism is used to rinse the inner wall of catheter-type medical devices. The adjustment mechanism is disposed on the rotating plate 3 for adjusting the rinsing angle of the rinsing mechanism. The delivery mechanism is disposed at the bottom end of the delivery pipe 4 for delivering rinsing fluid into the delivery pipe 4. The catheter-type medical device is secured to the support 2, so that the rinsing mechanism is located inside the catheter-type medical device. The inside of the medical device is rinsed through the delivery mechanism, the delivery pipe 4, and the rinsing mechanism. The rinsing angle is adjusted by the adjustment mechanism, thereby improving the rinsing efficiency and effect of the catheter-type medical device and minimizing the impact on the particle detection effect of the catheter-type medical device.

[0028] The rotating mechanism includes a gear ring 5, a drive gear 6, and a first motor 7. The gear ring 5 is fixedly connected to the bottom end of the rotating plate 3. The drive gear 6 is located at the bottom end of the rotating plate 3 and meshes with the gear ring 5. The first motor 7 is installed in the bracket 2. The output end of the first motor 7 is fixedly connected to the drive gear 6. The first motor 7 drives the drive gear 6 and the gear ring 5 to rotate. When the gear ring 5 rotates, it drives the rotating plate 3 and the conveying pipe 4 to rotate.

[0029] The flushing mechanism includes a connecting hose 8, a flushing box 9, and nozzles 10. The multiple nozzles 10 are of different types. The connecting hose 8 is connected to the top end of the delivery pipe 4, and the flushing box 9 is connected to the top end of the connecting hose 8. There are multiple nozzles 10, and all of the multiple nozzles 10 are connected to the flushing box 9. The flushing fluid is delivered into the flushing box 9 through the delivery pipe 4, and the inner wall of the catheter-type medical device is flushed through the multiple nozzles 10.

[0030] The adjustment mechanism includes: a drive plate 11, a sliding shaft 12, a drive rod 13, and a first electric cylinder 14. Two drive plates 11 are provided, and the two drive plates 11 are mounted at the bottom of the rinsing box 9 via a swing assembly. Two sliding grooves are formed on the two drive plates 11, and the sliding shaft 12 is slidably disposed within the two sliding grooves. The drive rod 13 is slidably connected to the rotating plate 3. The first electric cylinder 14 is mounted at the bottom of the rotating plate 3, and its output end passes through the rotating plate 3 and is fixedly connected to the drive rod 13. The swing assembly includes: a fixed frame 15, a rotating seat 16, and a connecting plate 17. The fixed frame 15 is fixedly connected to the top of the conveying pipe 4, and the rotating seat 16... 6 is fixedly connected to the top of the fixed frame 15.

Two drive plates 11 are fixedly connected to one side of the two connecting plates 17 respectively. The first electric cylinder 14 drives the drive rod 13 to move. When the drive rod 13 moves, it drives the sliding shaft 12 to move in the sliding groove opened on the drive plate 11, thereby supporting the drive plate 11 and the two connecting plates 17 to rotate in the rotating seat 16, thereby driving the rinsing box 9 to swing, thereby adjusting the rinsing angle of the multiple nozzles 10.

[0031] The conveying mechanism includes a conveying box 18 and a connecting pipe 19. The bottom end of the rinsing box 1 is fixedly connected to a base frame 20.
