Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a peritoneal dialysis bag outlet plug breaker. Background Technology

[0002] Membrane dialysis is one of the important renal replacement therapies for patients with end-stage renal disease (ESRD). Patients usually need to operate it themselves at home for a long period of time, changing the dialysate multiple times a day. As a core consumable for treatment, the ease of use, safety, and reliability of the peritoneal dialysis bag design directly affect the patient's operating experience, treatment adherence, infection risk, and the final treatment outcome.

[0003] In the standard peritoneal dialysis bag usage procedure, a key step is that the patient or caregiver must manually break the outlet plug on the dialysis bag before connecting the infusion tubing. This outlet plug is typically made of brittle plastic and is designed to be broken open in one go to expose the sterile connection interface.

[0004] Although existing peritoneal dialysis bags employ an "easy-break" design, the outlet plug is notoriously difficult to break in practice, posing a significant challenge in both clinical practice and home care. This manifests in several ways: 1. A large number of peritoneal dialysis patients are elderly, often experiencing weakened hand strength, decreased dexterity, joint pain, or numbness. Applying sufficient force and precisely targeting the intended break point becomes exceptionally difficult for them. 2. The outlet plug is typically small and smooth, making it prone to slippage when attempting to break it, leading to breakage failure. 3. Repeated failed attempts by patients to break the plug can easily result in improper hand contact and contamination of the area near the outlet plug, significantly increasing the risk of aseptic technique disruption and peritonitis. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a peritoneal dialysis bag outlet plug breaker.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A peritoneal dialysis bag outlet plug breaker includes: a first lever, an elastic element disposed on the first lever, and a second lever disposed on the elastic element; the first lever and the second lever are connected by the elastic element, and a bend is provided between them.

[0008] Preferably, both the first lever and the second lever are U-shaped structures used to embed the infusion tube, the connecting tube, and the outlet plug.

[0009] Preferably, the second lever has a limiting groove in the U-shaped groove to lock the infusion tube.

[0010] Preferably, the first lever and the second lever are mirrored bevels at both ends of the bend.

[0011] Compared with the prior art, this application has the following beneficial effects:

[0012] This invention employs the lever principle, embedding the infusion tube, connecting tube, and outlet plug into a first lever and a second lever. The end point of the first or second lever at the bend joint serves as a fulcrum, while the second or first lever acts as a lever arm. By moving the end of the lever arm away from the bend joint, the outlet plug can be easily broken. This prevents the patient from lacking sufficient strength to break the outlet plug and avoids the problem of slippage when bending due to the small size of the outlet plug. It also prevents the patient from directly bending it with their hands, which could easily cause contact contamination. Attached Figure Description

The terms "comprising" or "including" indicate that the element or object preceding "comprising" encompasses the element or object listed following "comprising" or its equivalents, and do not exclude other elements or objects. Terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" are used only to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0021] Example 1:

[0022] like Figures 1 to 3 As shown, a peritoneal dialysis bag outlet plug breaker includes: a first lever 11, an elastic element 12 disposed on the first lever 11, and a second lever 13 disposed on the elastic element 12; the first lever 11 and the second lever 13 are connected by the elastic element 12, and a bending slit 15 is provided between them; both the first lever 11 and the second lever 13 are U-shaped structures for embedding an infusion tube 21, a connecting tube 22, and an outlet plug 23; a limiting groove 14 is provided in the U-shaped groove of the second lever 13 for locking the infusion tube 21; the first lever 11 and the second lever 13 are mirrored bevels at both ends of the bending slit 15.

[0023] The outlet plug 23 is connected to the infusion tube 21 via the connecting tube 22, and the infusion tube 21 is connected to the peritoneal dialysis bag (this is prior art, so it is not shown in the diagram).

[0024] When in use, the infusion tube 21, the connecting tube 22, and the outlet plug 23 are all embedded into the U-shaped grooves of the first lever 11 and the second lever 13.

[0025] Furthermore, to prevent the outlet plug 23 from loosening during bending, a limiting groove 14 is provided in the U-shaped groove of the second lever 13; as is well known, such as Figure 2 and Figure 3 As shown, the infusion tube 21 is sleeved on the connecting tube 22, so that the exposed end of the infusion tube 21 can be locked in the limiting groove 14. In this way, the outlet plug 23 is prevented from being pulled and displaced when bending.

[0026] When the infusion tube 21 is locked in the limiting groove 14, the outlet plug 23 is located on both sides of the bend 15 (e.g., Figure 3 When bending, the end of the first lever 11 or the second lever 13 near the bending seam 15 can be used as a fulcrum. At the same time, force is applied to the end of the second lever 13 or the first lever 11 away from the bending seam 15. The outlet plug 23 can be easily broken by moving away from the lever.

[0027] During the bending process, in order to prevent the outlet plug 23 from running out of the U-shaped groove of the first lever 11 and the second lever 13 during bending, the first lever 11 or the second lever 13 can be bent along the elastic member 12. After the outlet plug 23 breaks, the first lever 11 or the second lever 13 is released. Under the rebound action of the elastic member 12, the first lever 11 or the second lever 13 automatically resets, and the next operation can be performed.

[0028] In addition, to ensure that the outlet plug 23 breaks completely, the first lever 11 and the second lever 13 are mirrored bevels at both ends of the bending seam 15. This design helps the first lever 11 and the second lever 13 to come into contact with each other prematurely when bending, and also increases the bending angle of both.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
