[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please refer to the attached document.Figures 1-5 The embodiment of the present application provides a bubble monitoring device which is suitable for blood treatment equipment and is used for monitoring bubbles in liquid pipeline. The bubble monitoring device comprises a base 1 and a light shielding cover 2. The base 1 is provided with a fixed pipe groove 101 for embedding the liquid pipeline and a sensor embedded on the groove wall of the fixed pipe groove 101. The sensor can be one kind, for example, an infrared sensor, an ultrasonic sensor or at least two sensors with different types. The light shielding cover 2 is connected to the base 1 in an openable and closable mode and is used for covering the fixed pipe groove 101 to avoid the interference of ambient light on the monitoring accuracy of the sensor. In the present application, the light shielding cover 2 comprises an outer plate 21 and a light shielding soft pad 22 connected to the inner side of the outer plate 21. The light shielding soft pad 22 can be made of plastic, rubber, silica gel or the like and can be elastically deformed. The light shielding soft pad 22 can at least cover the fixed pipe groove 101 and tightly cover the fixed pipe groove 101 by abutting against the surface of the base 1 when the light shielding cover 2 is closed.

[0029] In this way, the bubble monitoring device provided by the present application can cover the fixed pipe groove 101 of the fixed liquid pipeline by arranging the light shielding cover 2 and tightly cover the fixed pipe groove 101 by arranging the light shielding soft pad 22 on the inner side of the light shielding cover 2, thereby avoiding the problem that the poor light shielding effect caused by the large gap between the cover and the pipeline affects the monitoring accuracy of the sensor. It can be seen that the bubble monitoring device provided by the present application can eliminate the interference of ambient light on the sensor by arranging the light shielding cover 2 and the light shielding soft pad 22 on the inner side of the cover, effectively improve the monitoring accuracy of the sensor and solve the false alarm problem of the bubble monitoring device caused by ambient light. At the same time, the good light shielding effect also enables the sensor to use the infrared sensor and the ultrasonic sensor with high sensitivity and high detection accuracy, thereby enhancing the monitoring accuracy of the sensor from this perspective.

[0030] The outer plate 21 can be a flat plate or an arc-shaped plate. Preferably, the outer plate 21 can be an arc-shaped plate.

[0031] Further, the light shielding soft pad 22 at least has a part for extending into the fixed pipe groove 101. For example, in one specific embodiment, as shown in Figure 1 and Figure 2 the light shielding soft pad 22 comprises a convex strip 222 and extension wings 221 located on both sides of the convex strip 222. The convex strip 222 is used for extending into the fixed pipe groove 101, and the extension wings 221 are used for abutting against the surface of the base 1 provided with the fixed pipe groove 101.

[0032] In this way, by extending the wings 221, the light shielding soft pad 22 can fully cover the light shielding groove, and by the protrusions 222, the liquid pipe in the groove can be more tightly covered and the gap between the liquid pipe and the light shielding cover 2 can be filled to avoid the light entering the gap and causing interference; and by setting the depth of the protrusions 222 of the light shielding soft pad 22 extending into the pipe fixing groove 101, the protrusions 222 can slightly abut against the liquid pipe to enhance the fixing of the liquid pipe and prevent the liquid pipe from shaking due to external pulling and the like, which can affect the monitoring accuracy of the sensor.

[0033] In some embodiments, as shown in Figure 1 and Figure 2 , the pipe fixing groove 101 is provided with guide surfaces 102 on both sides of the groove opening, which can be arc surfaces or inclined planes and gradually expand outward along the direction from the groove bottom to the groove opening; at the same time, the size of the protrusions 222 in the width direction of the pipe fixing groove 101 gradually increases along the direction close to the outer plate 21, that is, the size of the protrusions 222 in the width direction of the pipe fixing groove 101 gradually decreases along the direction away from the outer plate 21, and the side surfaces of the protrusions 222 on both sides are matched with the guide surfaces 102, for example, the side surfaces of the protrusions 222 on both sides are also provided as arc surfaces or inclined planes. In this way, when the light shielding cover 2 is closed, the protrusions 222 can be smoothly and accurately inserted into the pipe fixing groove 101.

[0034] In some embodiments, as shown in Figure 1 and Figure 3 , the protrusions 222 have protruding portions 2221 at both ends in the length direction, which are higher than the middle region, so as to extend deeper into the pipe fixing groove 101; and the top end surface of the protruding portions 2221 is provided as a gradually inclined inclined surface along the length direction or an arc surface with gradually changing height. In this way, at both ends in the length direction of the pipe fixing groove 101, the protrusions 222 of the light shielding soft pad 22 are embedded deeper, which can more tightly cover the area at the end of the pipe fixing groove 101 and gently press the liquid pipe in the groove, preventing the gap at the end of the pipe fixing groove 101 from entering light and causing interference to the sensor.

[0035] The connection between the light shielding soft pad 22 and the outer plate 21 can be adhesive or the light shielding soft pad 22 can be injection molded on the outer plate 21 to form an integral structure with the outer plate 21. For example, after the outer plate 21 is formed, it can be injection molded or coated to make the light shielding soft pad 22 injection molded on the outer plate 21 to form an integral structure with the outer plate 21. In this way, the light shielding soft pad 22 has high stability and durability and will not easily be warped due to frequent opening and closing.

[0036] The light shielding cover 2 is further movably connected with a locking buckle and a locking member for locking the locking buckle, the locking buckle has a hook portion, and the base 1 is provided with a pin 15 for the hook to hook. In this way, after the hook of the locking buckle hooks the pin 15, the locking buckle can be stably locked on the base 1 under the locking action of the locking member, thereby enhancing the locking stability of the light shielding cover 2, and preventing the light shielding cover 2 from being popped open by slight impact and affecting the monitoring of the sensor.

[0037] Specifically, the locking buckle can be in the form of a plate body, and the middle part of the locking buckle is rotatably connected to the light shielding cover 2 in the direction from the light shielding cover 2 to the base 1, and one end forms a pressing portion, and the inner side of the other end is provided with a hook facing the base 1; the elastic member can be a spring, one end of which abuts against the light shielding cover 2 and the other end of which abuts against the locking buckle. Specifically, it can be a torsion spring, the inside of the locking buckle is provided with a fixed shaft, the torsion spring is sleeved on the fixed shaft, and the end portion of the torsion spring abuts against the light shielding cover 2.

[0038] The sensor can be of two types, including an infrared sensor and an ultrasonic sensor.

At the same time, the groove wall of the fixed pipe groove 101 is provided with a notch 103, the fixed block 131 is used to fill the notch 103, and the surface with the sensor probe forms the groove wall of the fixed pipe groove 101 at the notch 103 area, so that the sensor is in direct contact with the liquid pipeline, ensuring the monitoring accuracy.

[0040] The fixed top block can be a block or a plate with an arc surface, or it can be a whole U-shaped tube. At the same time, in some embodiments of the present application, a protective sleeve 14 is arranged between the fixed block 131 and the inner wall of the notch 103, which is circumferentially sleeved on the outside of the fixed block 131.
