Description

Technical Field

[0001] This utility model relates to the field of medical material packaging technology, and specifically discloses an integrated device for automatic bubble removal and detection during the filling process of medical gel. Background Technology

[0002] Medical gels (such as ultrasound coupling agents and surgical anti-adhesion gels) are widely used in the medical field, and their packaging process requires extremely high purity and uniformity. Due to the high viscosity of gels, air bubbles are easily incorporated during production. These air bubbles can affect product performance and may even pose risks to clinical use. Currently, medical gels are mainly packaged using canning production lines, but existing technologies still have significant shortcomings.

[0003] Traditional centrifugal degassing is incomplete in treating high-viscosity gels, often leaving residual bubbles with diameters exceeding the medical standard of 50μm. Secondly, bubble detection primarily relies on offline sampling, failing to achieve real-time quality monitoring during production. Furthermore, the independent operation of degassing, detection, and filling equipment not only leads to low production efficiency but also increases the risk of contamination in intermediate stages. Therefore, an integrated device for automatic bubble removal and detection during the medical gel filling process is needed to solve this problem. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-3 An integrated device for automatic bubble removal and detection during the filling process of medical gel includes a barrel 1 and a buffer tank 2. The barrel 1 is equipped with a centrifugal degassing mechanism. The lower end of the barrel 1 is equipped with a discharge pipe 8, and the other end of the discharge pipe 8 is connected to the buffer tank 2. A first pump body 10 is installed on the outer wall of the discharge pipe 8. A vacuum pump 11 is installed on the upper end of the buffer tank 2. The lower end of the buffer tank 2 is connected to a filling pipe 12. A connecting pipe 14 is connected to the outer wall of the filling pipe 12. The upper end of the barrel 1 is connected to an inlet pipe 13. The other end of the connecting pipe 14 is connected to the inlet pipe 13. A second pump body 15 is installed on the outer wall of the connecting pipe 14.

[0023] A high-frequency ultrasonic probe 16 is embedded in the outer wall of the filling tube 12. A mounting plate 17 is fixedly connected to the lower end face of the buffer tank 2. A visual inspection probe 18 located below the high-frequency ultrasonic probe 16 is provided on the outer wall of the mounting plate 17 near the filling tube 12.

[0024] In this embodiment: the gel raw material enters the centrifuge cylinder 4 inside the tank 1 through the feed pipe 13. The drive motor 5 drives the centrifuge cylinder 4 to rotate at high speed to achieve centrifugal degassing. The degassed gel is then transported to the buffer tank 2 by the first pump body 10 through the discharge pipe 8. The vacuum pump 11 maintains a negative pressure environment inside the tank to further eliminate bubbles. Subsequently, the gel is filled through the filling pipe 12. During the process, the high-frequency ultrasonic probe 16 and the visual inspection probe 18 simultaneously detect bubbles. Defective products can be returned to the tank 1 for reprocessing through the connecting pipe 14 via the second pump body 15. This device achieves integrated operation of automatic bubble removal and detection through the synergistic effect of centrifugal degassing, vacuum assistance, dual-mode detection, and closed-loop reflux. This utility model adopts a combination of centrifugal degassing and vacuum assistance to significantly improve the bubble removal efficiency. It integrates a high-frequency ultrasonic and visual dual-mode detection system to achieve real-time online detection of bubbles with high detection accuracy. Furthermore, the closed-loop reflux design enables automatic rework of defective products, reducing material waste.

[0025] As a technical optimization of this utility model, the centrifugal degassing mechanism includes a centrifugal cylinder 4 rotatably connected to the inside of the barrel 1 via a bearing 3. The discharge port of the centrifugal cylinder 4 is rotatably connected to the discharge pipe 8 via a rotating joint 9. A connecting frame 6 is fixedly connected to the upper end face of the centrifugal cylinder 4 via a connecting rod 7. A drive motor 5 with its output end fixedly connected to the connecting frame 6 is installed on the upper end face of the barrel 1.

[0026] In this embodiment: the drive motor 5 is started, the drive motor 5 drives the connecting frame 6 to rotate, and then drives the centrifuge cylinder 4 to rotate at high speed through the connecting rod 7. The centrifugal force generated by the high speed rotation causes the less dense bubbles to gather towards the center of rotation, while the high density gel moves outward, thereby realizing gas-liquid separation and bubble removal.

[0027] As a technical optimization of this utility model, the outer wall of the filling tube 12 is provided with an annular transparent observation window 19.

[0028] In this embodiment, the annular transparent observation window 19 serves as both a manual visual inspection window and an optical inspection channel for the visual inspection probe 18.

[0029] As a technical optimization of this utility model, solenoid valves are provided on the outer walls of the discharge pipe 8, the filling pipe 12 and the connecting pipe 14.

[0030] In this embodiment, solenoid valves are installed on the outer walls of the discharge pipe 8, the filling pipe 12 and the connecting pipe 14 to facilitate the opening and closing of the discharge pipe 8, the filling pipe 12 and the connecting pipe 14.

[0031] As a technical optimization of this utility model, the first pump body 10 is a peristaltic pump.

[0032] In this embodiment, by using a peristaltic pump as the first pump body 10, both the shearing bubbles generated by traditional pump bodies can be avoided, and the delivery process can be fully enclosed and sterile.

[0033] As a technical optimization of this utility model, the outer walls of the barrel 1 and the buffer tank 2 are fixedly connected with a bracket 20.

[0034] In this embodiment, the bracket 20 facilitates the support of the barrel 1 and the buffer tank 2.

[0035] As a technical optimization of this utility model, the outer wall of the bracket 20 is provided with a controller, and the drive motor 5, the first pump body 10, the vacuum pump 11, the second pump body 15, the high-frequency ultrasonic probe 16, the visual inspection probe 18 and the solenoid valve are all electrically connected to the controller.

[0036] In this embodiment: the controller automatically adjusts the speed of the drive motor 5 and controls the vacuum pump 11 to make the buffer tank 2 reach the set negative pressure; during operation, the first pump body 10 delivers the degassed gel to the buffer tank 2, while the high-frequency ultrasonic probe 16 and the visual inspection probe 18 detect bubbles in real time. If it is qualified, the filling is started; if it is not qualified, the gel is returned to the barrel 1 for reprocessing through the second pump body 15, realizing fully automatic closed-loop control.

[0037] The working principle and usage process of this utility model are as follows: During use, the controller first starts the drive motor 5 to rotate the centrifuge drum 4 at high speed, causing the gel raw material entering through the feed pipe 13 to undergo centrifugal degassing. The degassed gel is then transported to the buffer tank 2 via the discharge pipe 8 under the action of the first pump 10 regulated by the controller. Simultaneously, the controller starts the vacuum pump 11 to maintain a set negative pressure inside the tank for further degassing. During the filling stage, the controller receives detection signals from the high-frequency ultrasonic probe 16 and the visual inspection probe 18 in real time. If the signals are qualified, the filling pipe 12 is opened for filling. If excessive bubbles are detected, the controller immediately controls the second pump 15 to return the defective product to the tank 1 for reprocessing via the connecting pipe 14. This utility model combines centrifugal degassing with vacuum assistance, significantly improving bubble removal efficiency. It integrates a high-frequency ultrasonic and visual dual-mode detection system to achieve real-time online bubble detection with high accuracy. Furthermore, the closed-loop reflux design enables automatic rework of defective products, reducing material waste.
