[0028] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 specific circumstances.

[0029] like Figure 1-Figure 4 As shown, this embodiment provides an integrated device of a blood purification pipeline, which is used to be connected to a blood purification device, and a pump head is provided on the blood purification device. The integrated device of the blood purification pipeline includes an integrated disk 1 and a plurality of pipeline assemblies 2, the integrated disk 1 includes a bottom plate 11 and a side plate 12 arranged around the bottom plate 11, and the side plate 12 and the bottom plate 11 are enclosed to form a accommodating space; a plurality of pipeline installation positions are provided on the side plate 12, and a plurality of pipeline assemblies 2 are installed in a plurality of pipeline installation positions one by one, and each pipeline assembly 2 corresponds to a pump head arrangement. The plurality of pipeline assemblies 2 include, but are not limited to, an arterial pipeline assembly, a venous pipeline assembly, a replacement fluid pipeline assembly, a fluid infusion pipeline assembly, and a waste fluid pipeline assembly. Exemplarily, the arterial pipeline assembly is used to connect the human artery and the blood purification device, the venous pipeline assembly is used to connect the human vein and the blood purification device, and the replacement fluid pipeline assembly is used to connect the replacement fluid to the venous fluid pipeline assembly. During clinical operation, the integrated disk 1 is fixed on the blood purification device, and then multiple pipeline components 2 are connected to the blood purification device and the human body one by one. Medical personnel do not need to connect and install each pipeline component 2, which greatly simplifies the installation steps, makes the operation easy, and can be operated by inexperienced personnel, reducing the workload and learning costs of medical personnel.

[0030] Specifically, the bottom plate 11 is also provided with a fixing groove 112, which is used to fix the integrated disk 1 to the blood purification device. Two fixing grooves 112 are arranged at intervals along the length direction of the bottom plate 11, and the two fixing grooves 112 are used to connect the fixing seat, and the integrated disk 1 is fixed to the blood purification device through the fixing seat.

[0031] The pipeline assembly 2 includes a pump tube 21 and two main pipelines 22. Each pipeline installation position includes a mounting hole 122. Two mounting holes 122 are arranged at intervals. A positioning groove 121 is arranged between the two mounting holes 122. The positioning groove 121 is used to position the pump head. The pump head and the pump tube 21 are both arranged in the accommodating space. The pump tube 21 is arranged around the circumference of the pump head. The rotation of the pump head drives the liquid in the pump tube 21 to flow, providing power for the liquid flow in the pipeline assembly 2. The two ends of the pump tube 21 are respectively connected to one end of the two mounting holes 122, and the other ends of the two mounting holes 122 are respectively connected to the two main pipelines 22. The main pipeline 22 is arranged outside the accommodating space, so that the length of the main pipeline 22 is not limited, and it is more convenient for the main pipeline 22 to be connected with the blood purification equipment and the human body.

[0032] The pipeline installation position also includes a first emergency hole 111, which is arranged on the bottom plate 11 and corresponds to the central hole of the pump head. When the blood purification device is powered off, a wrench can be used to pass through the first emergency hole 111 and cooperate with the central hole of the pump head to drive the pump head to rotate.

[0033] Furthermore, the integrated disk 1 also includes a reinforcing plate 13, which is arranged in the circumference of the side plate 12, and the reinforcing plate 13 is arranged perpendicular to the side plate 12, and the mounting hole 122 extends from the side plate 12 to the end of the reinforcing plate 13 away from the side plate 12. The mounting hole 122 is used for connecting the pump pipe 21 and the main pipe 22, and needs to have a certain length to ensure the reliability of the connection. If the thickness of the side plate 12 is too large, the weight of the integrated disk 1 will be increased. Therefore, by setting the reinforcing plate 13 perpendicular to the side plate 12, the mounting hole 122 extends from the side plate 12 to the width direction of the reinforcing plate 13, which not only meets the length requirement of the mounting hole 122, but also ensures the strength of the mounting hole 122.

[0034] Specifically, the mounting hole 122 includes a plug hole and a communication hole. The plug hole is located at both ends of the mounting hole 122, and the communication hole is located between the two plug holes. The diameter of the communication hole is smaller than the diameter of the plug hole. A positioning surface is formed between the communication hole and the plug hole. The pump pipe 21 and the main line 22 are respectively plugged into the two plug holes and abut against the positioning surface. The pump pipe 21 and the main line 22 are connected through the communication hole. In order to facilitate the connection of the pump pipe 21 and the main line 22, the pump pipe 21 and the main line 22 are plugged and connected with the mounting hole 122. In order to avoid the pump pipe 21 and the main line 22 not being plugged in place during installation, a communication hole with a hole diameter smaller than the plug hole is set in the middle of the mounting hole 122, so that two positioning surfaces are formed to respectively position the pump pipe 21 and the main line 22, while ensuring the connection between the pump pipe 21 and the main line 22. Further, in order to enhance the reliability of the connection between the pump pipe 21 and the main line 22, glue can be applied on the positioning surface, and the pump pipe 21 and the main line 22 are respectively bonded to the two positioning surfaces.

[0035] In order to ensure the orderliness of the arrangement of the main lines 22 in the multiple pipeline assemblies 2 on the blood purification device, the outer periphery of the side plate 12 is also provided with multiple pipeline guide positions, each pipeline guide position includes multiple guide grooves 15, and the guide grooves 15 are used to guide and fix the main lines 22. In this embodiment, multiple pipeline guide positions are arranged at intervals below the reinforcing plate 13, and the guide grooves 15 are arranged as semicircular grooves with the notches facing upward and / or downward, which is convenient for fixing the main lines 22 and can ensure the reliability of the fixation. The guide grooves 15 guide the main lines 22 to be arranged circumferentially around the side plate 12, which can not only ensure the orderliness of the main lines 22, but also save the occupied space.

[0036] Since one of the two main lines 22 in the partial pipeline assembly 2 is further divided into two sub-lines, only one of the two sub-lines needs to be selectively opened; or, only one of the main lines 22 of one pipeline assembly 2 and one of the main lines 22 of the other pipeline assembly 2 needs to be selectively opened. A pipeline selector 3 is provided on the blood purification device, so that the pipeline selector 3 can control the opening of a sub-line or a main line 22. The integrated disk 1 also includes a pipeline selector installation position, and the pipeline selector installation position includes an installation groove 14, and the pipeline selector 3 is installed in the installation groove 14. Two through holes 142 are arranged at intervals on the opposite side walls of the mounting groove 14, wherein the two through holes 142 on one side wall and the two through holes 142 on the other side wall are arranged one by one. The pipeline selector 3 includes a selection rod 31 and two clamping plates, the selection rod 31 is located between the two clamping plates, and the two main pipelines 22 respectively pass through the two through holes 142 on one side wall and then respectively pass out from the two through holes 142 on the other side wall, one of the main pipelines 22 is located between one of the clamping plates and the selection rod 31, and the other main pipeline 22 is located between the other clamping plate and the selection rod 31, and the selection rod 31 can selectively move toward a direction close to one of the two clamping plates to close one of the main pipelines 22 so that the other main pipeline 22 is opened.

[0037] A second emergency hole 141 is provided at the bottom of the mounting groove 14 . When the blood purification device is powered off, the position of the selection rod 31 can be adjusted through the second emergency hole 141 .

[0038] Furthermore, in order to facilitate the installation and fixation of the main pipe 22 and the installation groove 14, the through hole 142 and the top of the side wall of the installation groove 14 are connected to form a through groove 143, and the through groove 143 gradually shrinks from the end away from the through hole 142 to the end close to the through hole 142. The main pipe 22 enters the through hole 142 from the through groove 143, and the notch of the end of the through groove 143 away from the through hole 142 is set to be larger than the communication port between the through groove 143 and the through hole 142, which not only facilitates the main pipe 22 to enter the through hole 142 through the through groove 143, but also prevents the main pipe 22 from easily slipping out of the through hole 142.

[0039] In this embodiment, there are seven pipeline installation positions, three pipeline installation positions are arranged on each of the two side plates 12 extending in the length direction of the integrated disk 1, and one pipeline installation position is arranged on one of the side plates 12 extending in the width direction of the integrated disk 1. That is, the integrated device of the blood purification pipeline can install seven pipeline components 2, and the aperture of the mounting hole 122 on different pipeline installation positions is not limited. The aperture of the mounting hole 122 is matched according to the diameter of the main line 22 in the pipeline component 2 connected thereto. Since only part of the pipeline components 2 need to selectively open or close one of the main lines 22, the pipeline selector installation position is set close to the pipeline installation position of the pipeline component 2 that needs to selectively open or close one of the main lines 22. In this embodiment, there are two pipeline selector installation positions, one pipeline selector installation position corresponds to one of the pipeline installation positions on one of the side plates 12, and the other pipeline selector installation position is set on another side plate 12 extending in the width direction of the integrated disk 1.

[0040] Furthermore, since the installation position of the integrated disk 1 on the blood purification device is fixed, in order to facilitate the connection of different types of pipeline components 2 with corresponding connection positions on the blood purification device, the installation positions of different types of pipeline components 2 on the integrated disk 1 are pre-set, in order to reduce the risk of incorrect installation of different types of pipeline components 2 in multiple pipeline components 2, such as Figure 4 As shown, each pipeline installation position is provided with a position mark 113 of a corresponding type of pipeline assembly 2. In this embodiment, the position mark 113 includes graphic symbols such as "△", "□", "◎", etc., and different graphic symbols represent different types of pipeline assemblies 2.

[0041] The blood purification treatment modes include treatment modes for single circulation systems, treatment modes for dual circulation systems, and treatment modes for systems with more than dual circulation systems, etc. Different treatment modes require different numbers and types of pipeline components 2. The number and type of pipeline components 2 on the integrated device of the blood purification pipeline can be set according to different treatment modes. In order to facilitate the blood purification device to obtain the number and type of pipeline components 2 on the integrated device of the blood purification pipeline, an identification position 16 is also provided in the circumference of the side plate 12, and the identification position 16 is used to paste an identification code, which contains the number and type information of the pipeline components 2. A camera is provided on the blood purification device, and the camera scans the identification code to obtain the number and type of pipeline components 2 on the integrated device of the blood purification pipeline.

[0042] In this embodiment, the identification position 16 is provided on a reinforcing plate 13 on another side plate 12 extending in the width direction of the integrated disk 1 .

[0043] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
