[0008] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0009] Example 1 like Figure 1-8 As shown, the hanging plate 1 is provided with a hanging groove 2 at the upper end, a support plate 3 is provided in the middle of the front end, a mixing chamber 6 is provided at the bottom, and a plate cover 4 is rotatably connected to one side; a plurality of liquid adding grooves 5 are arranged in a horizontal array on the upper part of the support plate 3 and can be detachably connected to the liquid adding tank 18; an interface 20 is provided at the bottom of the liquid adding tank 18 to connect to the liquid adding pipe 17, and a cover body 19 is provided at the upper end; a hole is provided in the middle of the liquid adding groove 5 to movably connect to the interface 20; In this embodiment, the liquid adding tank 18 is a cylindrical transparent container with scale lines marked on the tank body and a detachable cover 19 at the upper end for easy liquid addition. Furthermore, the liquid adding tube 17 is connected to the other liquid adding tubes 17 respectively, and the rear end is connected to the mixing chamber 6; it is used for liquids that need to be mixed; a liquid outlet 8 is provided at the bottom of the mixing chamber 6; when multiple liquids need to be mixed, the rear ends of multiple liquid adding tubes 17 are merged into the mixing chamber 6, and a spiral guide plate is provided in the chamber. When the liquid flows in, a rotating vortex is formed to promote rapid and uniform mixing; the diameter of the liquid outlet 8 at the bottom of the mixing chamber 6 is slightly larger than the diameter of the liquid adding tube 17, and is connected to the main input pipeline of the blood purification equipment. The liquid outlet 8 is provided with a one-way valve to prevent blood from backflowing and contaminating the mixed liquid; Furthermore, the liquid adding tubes 17 are connected to the interfaces 20 in the blood purification device respectively, and are used for liquids that need to be used separately. When a certain liquid needs to be infused separately, the connecting ring 16 of the corresponding liquid adding tube 17 is directly connected to the independent input interface 20 of the blood purification device. The liquid directly reaches the device through the liquid adding tube 17 to avoid mixing with other liquids. The paths of each liquid adding tube 17 are independent. Furthermore, a connecting ring 16 and a detachable connecting interface 20 are provided at the front end of the liquid adding tube 17; Furthermore, a plurality of suction cups 21 are arranged in an array at the lower rear end of the hanging plate 1 to assist the hanging slot 2 in fixing. By manually pressing the exhaust, the suction and fixation on the wall or equipment surface are achieved, forming a double fixing structure with the hanging slot 2, which is suitable for different usage scenarios, such as bedside, equipment side bracket, etc., to prevent the device from shaking and affecting the accuracy of fluid infusion. Furthermore, a display 15 is provided at the front end of the plate cover 4, and a groove is provided at the bottom for connecting the liquid adding tube 17; the display 15 displays in real time the current flow rate (unit: mL / h) of each liquid adding tube 17, the internal pressure of the mixing chamber 6 (unit: kPa), the remaining capacity of the liquid adding tank 18 and other parameters, supporting medical staff to set the target flow rate or mixing ratio through the touch screen; a wire groove for the liquid adding tube 17 is provided below the display 15, and an elastic rubber ring is provided at the groove, which automatically seals the liquid adding tube 17 when passing through to prevent dust from entering the interior of the plate cover 4.
[0010] Furthermore, a plurality of control columns 7 are arranged in an array at the front end of the hanging plate 1; a hole is provided in the middle of the control column 7 to accommodate a motor 10, and an abutment ring 9 is provided at the front end; the output shaft at the front end of the motor 10 is fixedly connected to a sliding sleeve 11; the sliding sleeve 11 is slidably connected to a sliding column 12; a cover plate 14 is provided at the front end of the sliding column 12; In this embodiment, an independent control column 7 is provided at the front end of the hanging plate 1 corresponding to each liquid adding tube 17. The output shaft of the motor 10 is connected to the sliding sleeve 11 via a spline. The inner wall of the sliding sleeve 11 is provided with a linear bearing, which forms a sliding pair with the sliding column 12 fixed to the front end of the control column 7. The extrusion column 13 is rotatably connected to the cover plate 14 via a bearing and can roll freely to reduce wear on the liquid adding tube 17. Furthermore, a plurality of extrusion columns 13 are arranged in a circumferential array at the lower end of the cover plate 14; the extrusion columns 13 are rotatably connected to the cover plate 14; Furthermore, one side of the middle portion of the liquid adding tube 17 is in close contact with the inner wall of the abutment ring 9, and the other side is movably connected to the extrusion column 13; the liquid adding tube 17 is made of a silicone hose. Furthermore, the abutment ring 9 is a semicircular ring, and its diameter is slightly larger than the array diameter of the extrusion columns 13; In this embodiment, the liquid adding tube 17 passes between the inner surface of the semicircular abutment ring 9 and the extrusion column 13. The inner diameter of the abutment ring 9 is 0.5-1 mm larger than the outer diameter of the liquid adding tube 17, forming a limited space. When the motor 10 drives the sliding sleeve 11 to rotate, the cover plate 14 drives the extrusion column 13 to intermittently squeeze the liquid adding tube 17. Therefore, a certain amount of liquid is circulated with each rotation of a certain angle, thereby simultaneously controlling the amount and flow rate of the liquid. In this embodiment, when the device is in use, the hanging plate 1 is hung in a suitable location, such as a hospital bed or a medical equipment stand, through the hanging slot 2. At the same time, the suction cup 21 at the lower rear end of the hanging plate 1 assists in fixing the hanging slot 2 to enhance the stability of the device. According to the need for fluid replenishment, the liquid adding tank 18 is detachably connected to the liquid adding tank 5 on the support plate 3. The interface 20 at the bottom of the liquid adding tank 18 is movably connected to the hole in the middle of the liquid adding tank 5 to ensure that the liquid adding tank 18 is securely installed. For liquids that need to be mixed, the liquid in the corresponding liquid adding tank 18 is connected to the mixing chamber 6 through the liquid adding tube 17. The liquid adding tube 17 is connected to the other liquid adding tubes 17, and the rear end is connected to the mixing chamber 6. The liquids in the mixing chamber 6 are mixed to form a balanced liquid, which flows out from the liquid outlet 8 at the bottom of the mixing chamber 6 and enters the blood purification device; For liquids that need to be infused independently, the liquid adding tube 17 of the liquid adding tank 18 is directly connected to the interface 20 in the blood purification device; the connecting ring 16 at the front end of the liquid adding tube 17 is detachably connected to the interface 20, ensuring that the liquid can be independently and accurately infused into the blood purification device; The infusion of liquid is controlled by the control column 7 arranged in the array at the front end of the hanging plate 1. When the motor 10 is working, the sliding sleeve 11 slides on the sliding column 12, driving the squeezing column 13 to squeeze the liquid adding tube 17, thereby driving the flow of liquid. By controlling the terminal speed of the motor 10, the flow rate of the liquid is controlled, and precise control of the liquid infusion speed is achieved.
[0011] Example 2 In this embodiment, 3-4 extrusion columns 13 are evenly distributed around the circumference of the lower end of the cover plate 14, arranged in a 120° or 90° array. A semi-circular abutment ring 9 is fixed to the front end of the control column 7, providing a support surface for the liquid adding tube 17, forming an extrusion channel. When the motor 10 drives the cover plate 14 to rotate, the extrusion columns 13 sequentially contact the liquid adding tube 17 and squeeze the tube wall. When the extrusion columns 13 rotate to the position of the abutment ring 9, the liquid adding tube 17 is flattened to form a sealing section, preventing liquid backflow. As the extrusion columns 13 continue to rotate away, the liquid adding tube 17 elastically recovers, generating negative pressure to suck in liquid, realizing a cycle of extrusion-delivery-release. All the squeezing columns 13 and the liquid adding tube 17 maintain a minimum squeezing distance, the liquid adding tube 17 is in a naturally stretched state, the flow cross-sectional area is maximized, and the liquid flows at the set maximum flow rate; The extrusion frequency is changed by adjusting the speed of the motor 10. The faster the speed, the more times the extrusion column 13 circulates and squeezes the liquid adding tube 17, and the more liquid flows per unit time; thereby the flow rate of the device is controlled; at the same time, the flow rate of the liquid can be measured by counting the number of extrusions.
[0012] In summary, the present invention can meet the needs of simultaneous rehydration of multiple liquids by providing multiple liquid adding tanks 18, and can achieve more precise control over the amount and speed of rehydration of each liquid, thereby avoiding the situation where excessive or insufficient rehydration affects the treatment effect and safety of the patient, and effectively ensures the maintenance of fluid balance in the patient's body during the blood purification process; At the same time, by setting up a mixing chamber 6, when liquids need to be mixed and used, the corresponding liquids can be connected to the mixing chamber 6 to form a balanced liquid to meet some special treatment needs; and when independent infusion of liquids is required, the liquid adding tube 17 can be directly connected to the blood purification equipment, ensuring the correct infusion method of liquids of different properties and improving the applicability and versatility of the device.
