[0002] Peritoneal dialysis is a kidney replacement therapy similar to artificial blood purification. In current technologies, automated peritoneal dialysis (APD) is commonly used to automate the peritoneal dialysis process, providing patients with more freedom of movement.

[0003] Existing peritoneal dialysis machines require the use of consumable cartridges to deliver peritoneal dialysis drugs. These cartridges need to be loaded in a specific manner and require a significant portion of the peritoneal dialysis machine's sides for fixation. Common consumable cartridges are thin-film chamber cartridges consisting of a cartridge body and flexible membranes on both sides, requiring complex peritoneal dialysis equipment for control and incurring high costs. Therefore, there is a need in the art for a consumable cartridge that is low-cost to manufacture and easy to use. Utility Model Content

When assembling or disassembling the consumable box, the elastic arm can be pressed to lock and unlock the consumable box from the application equipment, effectively simplifying the installation method of the consumable box in the application equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides a consumable box, comprising:

[0006] The housing body has a docking portion and a pipeline connection portion;

[0007] At least one side of the housing body is provided with an elastic arm, a first end of the elastic arm is connected to the docking portion, and a second end of the elastic arm extends from the docking portion to the pipe connection portion, with the second end of the elastic arm located above the pipe connection portion.

[0008] The elastic arm can approach the housing body under external force and move away from the housing body under its own elastic force until it returns to its initial position.

[0009] In one embodiment, a positioning boss is formed on the side of the elastic arm opposite to the housing body.

[0010] In one embodiment, the elastic arm includes a connecting portion and a clamping portion, the clamping portion being connected to the side of the housing body via the connecting portion, and the gap between the clamping portion and the side of the housing body gradually increasing along the mating portion toward the pipeline connecting portion.

[0014] In one embodiment, the joint between the elastic arm and the housing body is integrally injection molded.

[0015] In one embodiment, the elastic arm is detachably connected to the housing.

[0016] In one embodiment, a magnetic attraction element is provided at the first end of the elastic arm and / or on the side of the housing body, and the elastic arm is magnetically connected to the housing body.

[0017] Accordingly, this utility model also provides a peritoneal dialysis device, including the consumable box described in any one of the above.

[0018] The embodiments described in this utility model can be implemented individually or in any combination, unless obviously contradictory or otherwise specified in an explicit manner.

[0019] Implementing this utility model has the following beneficial effects:

[0020] In this embodiment, the second end of the elastic arm of the consumable box extends above the tubing connection. When installing or removing the consumable box, the elastic arm can be pressed outside the mounting slot of the application device to lock and unlock the consumable box.

[0022] Figure 2 This is a schematic diagram of the main structure of the consumable box in this utility model;

[0023] Figure 3 yes Figure 2 A magnified structural diagram of point A in the middle. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0025] The consumable box of this utility model can be locked and unlocked between the consumable box and the application device by pressing the elastic arm 2 during the installation and removal of the consumable box. The locking and unlocking speed is fast and efficient, which effectively simplifies the installation method of the consumable box in the application device.

[0026] In one specific embodiment of this utility model, such as Figures 1 to 3 As shown, the consumable box includes a housing body 1, which has a docking portion 11 and a pipe connection portion 12. At least one side of the housing body 1 is provided with an elastic arm 2. The first end of the elastic arm 2 is connected to the docking portion 11, and the second end of the elastic arm 2 extends along the docking portion 11 towards the pipe connection portion 12, with the second end of the elastic arm 2 located above the pipe connection portion 12. The first end of the elastic arm 2 can also be referred to as the fixed end, and the second end of the elastic arm 2 can also be referred to as the free end. The elastic arm 2 can approach the housing body under the action of an external force, and after the external force is reduced or eliminated, it moves away from the housing body 1 under its own elastic force until it returns to its initial position. The initial position of the elastic arm 2 is the position of the elastic arm 2 in its natural state when no external force is applied.

[0027] Specifically, the second end of the flexible arm 2 is located above the tubing connection portion, meaning that the second end of the flexible arm 2 is closer to the tubing connection portion of the consumable box than to the mating portion. In particular, the second end of the flexible arm 2 should be able to protrude outside the mounting slot after the consumable box is inserted into the mounting slot of the application device for user operation.

[0028] The consumable box provided in this embodiment has a housing body 1 that can be connected to application equipment such as a peritoneal dialysis machine through the docking part 11. When the consumable box is connected to the application equipment, the pipeline connection part 12 of the consumable box needs to protrude outward from the mounting groove of the application equipment in order to facilitate pipeline connection.

[0029] When connecting the consumable box to the application device, pressing the second end of the elastic arm 2 causes it to retract inward, facilitating the insertion of the consumable box's mating part 11 into the application device. Releasing the elastic arm 2 then allows it to open outward, abutting against the application device and locking the consumable box securely in place. Since the second end of the elastic arm 2 is located above the pipe connection part 12, it is outside the mounting slot of the application device when the consumable box is installed. Therefore, when removing the consumable box, pressing the second end of the elastic arm 2 again disconnects the connection between the consumable box and the application device, allowing the consumable box to be removed.

[0030] Therefore, in this embodiment, the second end of the elastic arm 2 of the consumable box is located outside the mounting slot of the application device. When installing or removing the consumable box, the elastic arm 2 can be pressed outside the mounting slot of the application device to lock and unlock the consumable box and the application device. The locking and unlocking speed is fast and efficient, which effectively simplifies the installation method of the consumable box on the application device. Patients or medical staff can quickly and accurately install or replace the consumable box, reducing the difficulty of installing or removing the consumable box.

[0031] It should be noted that the peritoneal dialysis machine and other application equipment have an installation slot that is adapted to the shape of the consumable box. The docking part 11 of the consumable box can be inserted into the installation slot and the elastic arm 2 is used to press against the wall of the installation slot to complete the installation of the consumable box in the application equipment.

[0032] It should be noted that a flexible arm 2 may be provided on the side of the housing body 1. When installing the consumable box, the connecting part of the consumable box can be inserted into the installation slot of the application device by pressing the flexible arm 2 and the other side of the housing body 1 away from the flexible arm 2, and the consumable box can be pressed against the installation slot of the application device by the flexible arm 2 and the other side of the housing body 1 away from the flexible arm 2.

[0033] Alternatively, two elastic arms 2 can be provided on the side of the housing body 1. The two elastic arms 2 are located on opposite sides of the housing body 1. When installing the consumable box, the mating part of the consumable box can be inserted into the mounting groove by pressing the two elastic arms 2 at the same time, and the consumable box can be pressed against the mounting groove of the application device by the two elastic arms 2. This ensures that the elastic force of the consumable box 1 on the two elastic arms 2 is relatively balanced, thereby ensuring that the installation position of the consumable box 1 is accurate and without deviation.

[0034] Among them, such as Figure 1 and Figure 2 As shown, the length of the docking part 11 is greater than the length of the pipeline connection part 12 to ensure that when the consumable box is installed on the application equipment through the docking part 11, the contact area between the consumable box and the application equipment is larger, thereby ensuring the installation stability of the consumable box when it is docked to the application equipment.

[0035] In addition, the docking part 11 with a certain length can ensure that a liquid chamber with sufficient capacity can be formed inside the shell body 1, so as to ensure that the consumable box can hold a certain amount of dialysate, thereby ensuring a certain liquid transfer efficiency.

[0036] Furthermore, in order to achieve the intake and exhaust of liquid from the liquid chamber of the consumable cartridge, such as Figure 1 As shown, a liquid chamber is formed inside the housing body 1. A docking boss 13 is provided on the docking portion of the consumable box, and a pressure control port 14 is formed on the docking boss 13, which communicates with the liquid chamber of the consumable box. A corresponding docking groove is provided in the mounting slot of the application device. When the consumable box is placed in the mounting slot of the application device, the docking boss 13 of the consumable box tightly engages with the docking groove of the application device. The application device controls the pressure inside the liquid chamber through a pressure control device connected to the docking groove. For example, the pressure control device of the application device can inject or extract gas from the consumable box. Preferably, as... Figure 1 and Figure 2 As shown, the mating boss 13 is located on the surface of the mating part 11 away from the pipe connection part 12.

[0037] In this embodiment, to ensure that the mating boss 13 of the consumable box can accurately align with the mating slot in the application device mounting slot, such as Figures 1 to 3 As shown, a positioning boss 21 is formed on the side of the elastic arm 2 away from the housing body 1. When the consumable box is docked with the mounting slot of the application device, the positioning boss 21 can be used to determine the relative position between the consumable box and the application device, ensuring that the docking boss 13 of the consumable box can accurately dock with the docking slot in the application device, and ensuring the assembly accuracy between the consumable box and the mounting slot.

[0038] For example, a positioning hole can be formed in the inner wall of the mounting slot of the application device. The distance between the positioning hole and the bottom of the mounting slot is D3, and the distance between the positioning boss 21 and the bottom of the consumable box is D4. D3 and D4 are equal. When the elastic arm 2 abuts against the inner wall of the mounting slot, the displacement of the consumable box 1 is restricted by the cooperation of the positioning boss 21 and the positioning hole, thereby improving the fixing effect of the consumable box 1.

[0039] Preferably, the elastic arm 2 is made of an elastic material, so that when the consumable box is placed into the mounting slot of the application device and the elastic arm 2 is released, the elastic arm 2 can spring back and open, and adaptively fit against the inner wall of the mounting slot of the application device, so as to ensure that the consumable box and the mounting slot of the application device form a tight contact through elastic force, and ensure the installation stability of the consumable box.

[0040] Alternatively, the elastic arm 2 may include an elastic element, such as a spring, to provide the elastic arm 2 with its own elastic force.

[0041] Among them, such as Figures 1 to 3As shown, the elastic arm 2 includes a connecting portion 22 and a clamping portion 23. The clamping portion 23 is connected to the side of the housing body 1 through the connecting portion 22. The gap between the clamping portion 23 and the side of the housing body 1 gradually increases along the mating portion 11 towards the pipeline connection portion. In this embodiment, the clamping portion 23 is used to contact and clamp with the mounting slot of the application device, and the gradual gap between the clamping portion 23 and the housing body 1 further adapts to the mounting slot structure of different sizes and specifications, improving the installation adaptability of the consumable box to the application device.

[0042] For example, when the size of the mounting slot of the application device is small, the rebound amount of the elastic arm 2 is small, and a small gap is formed between the clamping part 23 and the side of the housing body 1. When the size of the mounting slot of the application device is large, the rebound amount of the elastic arm 2 is large, and a large gap is formed between the clamping part 23 and the side of the housing body 1.

[0043] Specifically, such as Figure 3 As shown, the connecting part 22 is an external protrusion formed on the side of the housing body 1, so as to increase the connection area between the abutting part 23 and the side of the housing body 1, thereby enhancing the connection strength and durability between the elastic arm 2 and the housing body 1.

[0044] In another embodiment, the connecting part 22 may also be a countersunk hole structure formed on the side of the housing body 1. The countersunk hole structure is provided with an elastic element such as a spring. The end of the elastic element away from the countersunk hole is connected to the first end of the elastic arm 2. When the second end of the elastic arm 2 is pressed, the elastic arm 2 moves toward the side of the housing body 1 and compresses the elastic element. When the elastic arm 2 is released, under the action of the elastic element, the elastic arm 2 rebounds and presses against the side wall of the mounting groove, thereby achieving the pressing and fixing of the consumable box.

[0045] In this embodiment, as Figure 1 and Figure 2 As shown, the second end of the elastic arm 2 is formed with an outward bend 24. The outward bend 24 extends away from the housing body 1, and the side of the outward bend 24 facing the housing body 1 is an arc surface, so as to further increase the distance between the second end of the elastic arm 2 and the side of the housing body 1, or the distance between the tails of the two elastic arms 2, so as to facilitate pressing the elastic arm 2 using the outward bend 24.

[0046] It should be noted that the gap between the connecting part 22 and the clamping part 23 gradually increases along the direction from the docking part 11 to the pipeline connection part, so that when the elastic arm 2 is pressed by the outer bend 24, the connecting part 22 can avoid the clamping part 23, providing a certain space for the deformation of the elastic arm 2.

[0047] In one embodiment of this utility model, the joint between the elastic arm 2 and the housing body 1 is integrally injection molded.

[0048] In another embodiment of this utility model, the elastic arm 2 is detachably connected to the housing body 1, so that the elastic arm 2 can be removed from the housing, thereby allowing the elastic arm 2 of the previous consumable box to be reassembled into the next consumable box when replacing the consumable box, which facilitates the reuse of the elastic arm 2.

[0049] The first end of the elastic arm 2 and / or the side of the housing body 1 are provided with magnetic attraction components, and the elastic arm 2 and the housing body 1 are magnetically connected to achieve quick assembly of the elastic arm 2 on the consumable box.

[0050] Specifically, the magnetic attractor can be provided only at the connecting part of the elastic arm 2, and a magnetic conductor is provided on the side of the housing body 1. The magnetic attractor can be a magnet, and the connecting part at the first end of the elastic arm 2 forms an insert groove. The magnet is embedded in the insert groove at the first end of the elastic arm 2. A magnetic conductor such as metal can be attached to the side of the housing body 1, and the outer protrusion of the elastic arm 2 is connected to the housing body 1 by the magnetic attraction between the magnet and the magnetic conductor.

[0051] Of course, the magnetic connector can also be installed on the side of the housing body 1 through the mounting slot, in which case the connecting part of the elastic arm 2 is provided with a magnetic conductor. The elastic arm 2 and the side of the housing body 1 can also be provided with magnetic connectors at the same time to magnetically connect the elastic arm 2 and the housing body 1.

[0052] Preferably, the size of the magnet is slightly smaller than the connecting part of the elastic arm 2. For example, the magnet has a rectangular structure, and the length and width of the magnet are 2-10mm smaller than the length and width of the connecting part, so as to ensure that there is a certain contact area between the magnet and the housing body 1, thereby ensuring the connection strength between the elastic arm 2 and the housing body 1.

[0053] Accordingly, this utility model also provides a peritoneal dialysis device, which includes the consumable box described in any of the above embodiments. The consumable box is assembled in the peritoneal dialysis device for controlling the delivery of peritoneal dialysis fluid. The peritoneal dialysis device possesses all the beneficial effects of the aforementioned consumable box, which will not be elaborated further here.

[0054] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
