[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0038] like Figure 1-Figure 3 As shown, the first embodiment of the present invention provides a consumable box for peritoneal dialysis, comprising:

[0039] The box body 1 is formed with a pressure chamber 11, a connecting chamber 12 and a docking portion 13;

[0040] At least one side of the box body 1 is provided with a locking member 2 and an elastic member 3, wherein the locking member 2 is connected to the elastic member 3; the locking member 2 can be displaced in a direction perpendicular to the side of the box body 1 to be inserted into or disengaged from the corresponding locking groove;

[0041] The docking portion 13 includes a docking port 131 protruding relative to the surface of the box body 1;

[0042] The pressure chamber 11 comprises a main pressure chamber 111 and a secondary pressure chamber 112 which are connected to each other, wherein the secondary pressure chamber 112 is arranged at one side of the main pressure chamber 111 and extends in the direction of the connection side;

[0043] The connecting chamber 12 is disposed at a side where the primary pressure chamber 111 and the secondary pressure chamber 112 are connected.

[0044] Preferably, the docking portion 13 is located on the back side of the box body 1 .

[0045] The elastic member can be elastically deformed under the action of an external force, and after the external force is eliminated, the elastic member can restore the locking member to an initial position. The elastic member can stabilize the locking member in the locking groove by its own elastic force, thereby fixing the consumable box in the installation groove to prevent the consumable box from loosening in the installation groove or even accidentally detaching from the installation groove.

[0046] When using the consumable box of the present invention, it is only necessary to apply pressure to the elastic member 3 when installing the consumable box, and then install the consumable box into the installation slot of the peritoneal dialysis device. When installed in place, the pressure control port on the installation slot is sealed and connected to the docking port 131, and the locking member 2 automatically enters the locking slot to reliably fix the consumable box to the installation slot. The connection and locking of the consumable box are completed in one action, and the operation is convenient. When removing the consumable box, it is only necessary to apply pressure to the elastic member 2, and then pull the consumable box out of the installation slot. Both disassembly and assembly can be operated with one hand, which is easy to use and has high disassembly and assembly efficiency.

[0047] Preferably, the consumable box is connected with a pipeline for peritoneal dialysis. Specifically, the connecting cavity 12 is connected with a liquid supply tube 41, a first branch tube 42, a liquid infusion tube 43 and a final tube 44; the side of the secondary pressure cavity 112 is connected with a second branch tube 45 and a waste liquid tube 46. These pipelines are used to transport peritoneal dialysis liquid or human waste liquid.

[0048] It should be noted that the main pressure chamber 111 is fluidically connected to the pressure control mechanism of the peritoneal dialysis device through the interface 131, and the pressure control mechanism of the peritoneal dialysis device can provide a predetermined pressure for the pressure chamber. Specifically, the pressure control mechanism provides the required pressure for the pressure chamber by injecting gas into the pressure chamber or extracting gas from the pressure chamber. Figure 5As shown, the connecting cavity 12 can be connected to the heating bag 51 through the liquid supply tube 41, the connecting cavity 12 can be connected to the liquid infusion bag 52 through the liquid infusion tube 43, the connecting cavity 12 can be connected to the last bag 53 through the last tube 44, the secondary pressure cavity 112 can be connected to the waste liquid collector 54 through the waste liquid tube 46, and the end of the human body tube 47 close to the box body of the consumable box is connected with the first branch tube 42 and the second branch tube 45, the first branch tube 42 is connected to the connecting cavity 12, the second branch tube 45 is connected to the secondary pressure cavity 112, and the end of the human body tube 47 away from the box body of the consumable box can be connected to the human peritoneal cavity 55.

[0049] By configuring the pressure chamber 11 to include a main pressure chamber 111 and a secondary pressure chamber 112 that are interconnected, the secondary pressure chamber 112 is arranged on one side of the main pressure chamber 111 and extends laterally; the connecting chamber and the secondary pressure chamber are arranged on the same side of the main pressure chamber, so that the height of the main pressure chamber 111 will not be restricted by the height of the secondary pressure chamber 112 and the connecting chamber 12, the height of the consumable box can be lowered for easy taking, while reducing the height restriction on the peritoneal dialysis device and reducing the space occupied by the peritoneal dialysis device.

[0050] The connecting chamber 12 and the secondary pressure chamber 112 are both long strip-shaped cavities. The secondary pressure chamber 112 is arranged below the connecting chamber 12. The connecting port of the secondary pressure chamber 112 and the main pressure chamber 111 is located at the intersection of the bottom surface and the side surface of the main pressure chamber 111. The secondary pressure chamber 112 has a confluence portion 113 that is lower than the main pressure chamber 111. The secondary pressure chamber 112 is arranged on one side of the main pressure chamber 111 and extends downward along the connecting side direction. It can form a liquid collection point that is lower than the bottom of the main pressure chamber 111 at the connection between it and the second branch pipe 45 and the waste liquid pipe 46. The waste liquid in the main pressure chamber 111 can be completely discharged from the secondary pressure chamber 112, reducing the liquid residue in the pressure chamber. Preferably, the position where the confluence portion 113 is connected to the waste liquid pipe 46 is close to the lowest point of the confluence portion 113. By providing the confluence part 113 and connecting the waste liquid pipe 46 to the confluence part 113, the peritoneal dialysis waste liquid from the human peritoneal cavity can be discharged more thoroughly from the consumable box to prevent the waste liquid from affecting the next peritoneal dialysis fluid perfusion.

[0051] Preferably, the locking member is connected to the box body through the elastic member. Figure 2 As shown, the locking member 2 can be arranged on the elastic member 3. The locking member 2 and the elastic member 3 are fixedly connected or integrally formed.

[0052] According to a first specific implementation of the elastic member 3 and the locking member 2 of the consumable box of this embodiment, as shown in Figure 2As shown, the elastic member 3 is an elastic arm, and the elastic arm includes a connecting portion 31 and a pressing portion 32, and the pressing portion 32 is connected to the side of the box body 1 through the connecting portion 31; the locking member 2 is a convex rib 21 provided on the side of the pressing portion 32 away from the box body 1. The pressing portion 32 can be made of elastic material so that it has a strong rebound ability when subjected to external pressure. The shape of the convex rib 21 is not limited, and can be a strip, square, round or other arbitrary shapes.

[0053] The gap between the abutting portion 32 and the side surface of the box body 1 gradually increases in the direction away from the connecting portion 31. In this embodiment, the abutting portion 32 is used to contact and abut with the installation slot of the external device, and the gradual gap between the abutting portion 32 and the box body 1 further adapts to the installation slot structure of different sizes, thereby improving the installation adaptability of the consumable box to different external devices.

[0054] Preferably, a set of locking members 2 and elastic members 3 may be provided on the side of the box body 1. When installing the consumable box, the consumable box can be firmly installed in the external device by pressing the elastic member 3 and the side opposite to the box body 1. Two sets of locking members 2 and elastic members 3 may also be provided on the side of the box body 1. For example, the two sets of locking members 2 and elastic members 3 are respectively located on two opposite sides of the box body 1. When installing the consumable box, the consumable box can be fixed in the external device by pressing two elastic members 3 at the same time and using two locking members 2, and it is ensured that the elastic force of the two locking members 2 on the consumable box is relatively balanced, thereby ensuring that the installation position of the consumable box is accurate and without deviation. The elastic member may be an elastic arm.

[0055] Among them, a bending portion 321 is formed at the end of the pressing portion 32, and the bending portion 321 extends toward the side away from the box body 1, and the bending portion 321 is an arc surface to further increase the distance between the pressing portion 32 and the side of the box body 1, so as to facilitate the use of the bending portion 321 to press the elastic arm.

[0056] Combination Figure 4 As shown, according to the second specific implementation of the elastic member 3 and the locking member 2 of this embodiment, the elastic member 3 can be a spring 33, the locking member 2 can be a locking tongue 22, the side of the box body 1 is provided with a slide groove 14, the locking tongue 22 is arranged in the slide groove 14, and the bottom of the locking tongue 22 is provided with a spring 33. In this embodiment, the locking tongue 22 can be extended and retracted in the slide groove 14, so as to be stuck in the corresponding locking groove. The end of the locking tongue 22 can be a curved surface structure 221, so that the locking tongue 22 can enter the locking groove more smoothly, or when the user pulls out the consumable box, the locking tongue 22 automatically retracts from the locking groove. With this embodiment, the structure is more compact.

[0057] Preferably, the box body 1 is rectangular, with a height greater than its width and a length greater than its height. By increasing the length of the box body 1, the box body 1 of the same height can accommodate more liquid, and by making the height of the box body 1 greater than its width, the docking port 131 can be higher from the bottom of the pressure chamber 11 to prevent accidental equipment vibration from causing liquid to cover the docking port 131. The docking port 131 is provided with a semi-permeable membrane (not shown) that can block the passage of liquid but allow gas to pass through.

[0058] Accordingly, if Figure 6-Figure 8 As shown, the second embodiment of the present invention provides a peritoneal dialysis device for installing the consumables box for peritoneal dialysis as described above to perform peritoneal dialysis, the peritoneal dialysis device is provided with a mounting groove 6, the back of the mounting groove 6 is provided with a pressure control port 61, and the side is provided with a locking groove 62. The pressure control port 61 is connected to the negative pressure pump 7 and is used to control the pressure in the pressure chamber 11. The mounting groove is used to accommodate and fix the consumables box, the pressure control port is used to connect to the docking port of the consumables box, and the locking groove is used to engage with the locking member of the consumables box to fix the consumables box.

[0059] Specifically, the locking groove may be located on an upper side surface, a lower side surface, a left side surface or a right side surface of the mounting groove.

[0060] The docking port 131 is arranged at the upper back side of the box body 1, and a balancing protrusion 132 is symmetrically arranged just below the docking port 131. A balancing groove 63 is arranged at the corresponding position of the mounting groove 6. Regarding the upper back side, it can be understood that the distance between the center of the docking port and the top of the back side of the box body is less than 50% of the back side height of the box body, for example, less than 40% of the back side height of the box body, less than 30%, less than 25%, less than 20%, less than 15%, or less than 10%. The cooperation of the balancing protrusion and the balancing groove makes the installation of the consumable box more reliable, and avoids the skewing of the consumable box due to the unbalanced upper and lower forces, thereby preventing the docking port from leaking.

[0061] When the consumable box needs to be installed in the installation slot 6, it is only necessary to apply pressure to the curved portion 321 of the consumable box, and then naturally place the consumable box into the installation slot 6 of the peritoneal dialysis device. The pressure control port 61 and the balance groove 63 are both provided with sealing rings; when the docking port 131 contacts the sealing ring of the pressure control port 61, the balance protrusion 132 also contacts the sealing ring in the balance groove 63, forming the same resistance, ensuring that the upper and lower parts of the consumable box are balanced in force during the installation process. When installed in place, the pressure control port 61 on the installation slot 6 is sealed and connected to the docking port 131, providing a predetermined pressure to the pressure chamber 11 during operation, and the locking member 2 automatically enters the locking groove 62 to reliably fix the consumable box to the installation slot 6. The connection and locking of the consumable box are completed in one action, and the operation is convenient. When removing the consumable box, it is only necessary to apply pressure to the locking member 2, and then naturally take the consumable box out of the installation slot 6.

[0062] In order to realize automatic flow control of the pipeline, a pipeline accommodating chamber 64 is provided on one side of the installation slot 6, and a pipeline fixing slot 65 is provided in the pipeline accommodating chamber 64; the pipeline fixing slot 65 is used to fix the corresponding liquid supply pipe 41, the first branch pipe 42, the liquid infusion pipe 43, the last pipe 44, the second branch pipe 45, the human body pipe 47 and the waste liquid pipe 46. The pipeline accommodating chamber 64 is also provided with a flow regulating mechanism for independently controlling the connection and flow of the liquid supply pipe 41, the first branch pipe 42, the liquid infusion pipe 43, the last pipe 44, the second branch pipe 45, the human body pipe 47 and the waste liquid pipe 46. The flow regulating mechanism includes a pressing head 66 and a telescopic motor 67. The pressing head 66 is connected to the telescopic motor 67 and can be driven by the telescopic motor 67 to radially press the corresponding pipe body to control the flow cross-section size of the corresponding position of the pipe body, thereby controlling the liquid flow in the pipe body. Specifically, the pipeline accommodating chamber 64 is provided with a door plate (not shown in the figure), and a matching mechanism is provided at a position on the door plate opposite to the pressing head 66. The pressing head 66 and the matching mechanism squeeze the pipe body from both sides, thereby controlling the flow cross-section size in the pipeline. The independent control means that the flow rate of each pipeline can be controlled separately as needed.

[0063] In addition, the present invention also provides a peritoneal dialysis system, comprising the peritoneal dialysis device as described above and a consumable box for peritoneal dialysis.

[0064] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
