[0002] The global market size for adult and pediatric blood concentrators reached RMB 60.7 billion in 2022. Industry research predicts that the global market size for adult and pediatric blood concentrators will reach RMB 85.417 billion by 2028, with a projected compound annual growth rate of 5.8% during the forecast period.

[0003] Existing protective covers for blood concentrator connectors are generally screwed directly onto the blood concentrator connectors via threads. The protective function is achieved through the fit between the protective cover and the blood concentrator connector. However, the contact area between the existing protective cover and the blood concentrator connector is small after installation, resulting in limited sealing and protection.

[0004] Therefore, it is necessary to invent a connector protection device for blood concentrators to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a connector protection device for a blood concentrator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connector protection device for a blood concentrator, comprising a protective cover body, a sealing plug inside the protective cover body, the sealing plug being a conical structure, and a cavity inside the sealing plug, a supporting rib fixedly disposed inside the cavity, the two ends of the supporting rib being connected to the middle of the two ends of the cavity respectively, a plurality of deformation grooves being provided sequentially from bottom to top on the outer side wall of the supporting rib, the deformation grooves being annular structures, and the cross-section of the deformation grooves being a "<" shaped structure, a plurality of protruding ribs being fixedly disposed sequentially from bottom to top on the outer side wall of the sealing plug, the outer surfaces of the plurality of protruding ribs being arc-shaped structures, and a deformation cavity being provided inside the plurality of protruding ribs, a connecting groove being opened at the bottom end of the inner side wall of the protective cover body, a connecting block being fixedly disposed at the bottom end of the sealing plug, and the connecting block being detachably inserted into the interior of the connecting groove.

[0007] Preferably, a sealing gasket is fixedly provided at the bottom end of the sealing plug, and the sealing gasket is in contact with the inner wall of the bottom end of the protective cover body.

[0011] Preferably, both the protective cover body and the sealing plug are made of PP material.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model sets up a protective cover body and a sealing plug. The protective cover body is screwed onto the connector of the blood concentrator through its internal thread, thus achieving the protection of the blood concentrator connector. The sealing plug can be inserted into the blood concentrator connector. The sealing plug and the protective cover body cooperate to achieve internal and external sealing protection of the blood concentrator connector, effectively improving the protection effect. Furthermore, the sealing plug is designed with a conical structure and has a cavity and supporting ribs inside. During the process of inserting the sealing plug into the blood concentrator connector, it is squeezed and deformed by the blood concentrator connector.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5 The device shown is a connector protection device for a blood concentrator, including a protective cover body 1. The protective cover body 1 has a sealing plug 2 inside, and the sealing plug 2 is a conical structure. The sealing plug 2 has a cavity 3 inside, and a support rib 4 is fixed inside the cavity 3. The two ends of the support rib 4 are respectively connected to the middle of the two ends of the cavity 3. The outer wall of the support rib 4 has a plurality of deformation grooves 5 from bottom to top. The deformation grooves 5 are annular structures, and the cross-section of the deformation grooves 5 is a "<" shaped structure. The design of the deformation grooves 5 allows the support rib 4 to undergo lateral deformation, thereby guiding the sealing plug 2 to deform from the outside to the inside.

[0023] The outer wall of the sealing plug 2 is provided with multiple ribs 6 from bottom to top. The outer surface of each rib 6 is an arc-shaped structure, and each rib 6 has a deformation cavity 7 inside. The design of the deformation cavity 7 allows the rib 6 to deform when it is squeezed by the inner wall of the blood concentrator connector. The deformed rib 6 can fit better with the inside of the blood concentrator connector.

[0024] A connecting groove 8 is provided at the bottom of the inner side wall of the protective cover body 1, and a connecting block 9 is fixedly provided at the bottom of the sealing plug 2. The connecting block 9 is detachably inserted into the inside of the connecting groove 8. The connecting block 9 and the connecting groove 8 are used to install the sealing plug 2 inside the protective cover body 1.

[0025] A sealing gasket 10 is fixedly provided at the bottom end of the sealing plug 2, and the sealing gasket 10 is in contact with the inner wall of the bottom end of the protective cover body 1. A sealing ring 11 with an annular structure is fixedly provided on the lower surface of the sealing gasket 10. A sealing groove 12 with an annular structure is opened inside the bottom end of the protective cover body 1. The sealing ring 11 and the sealing groove 12 are adapted to each other. The sealing gasket 10, the sealing ring 11 and the sealing groove 12 cooperate to improve the sealing effect between the sealing plug 2 and the protective cover body 1, thereby preventing residual raw materials in the blood concentrator connector from seeping into the space between the protective cover body 1 and the sealing plug 2 and affecting cleaning and maintenance.

[0026] Both the connecting block 9 and the connecting groove 8 have a convex cross-section. The connecting block 9 and the connecting groove 8 are connected by an interference fit. When the sealing plug 2 and the connecting block 9 are pulled, the connecting block 9 can deform and separate from the connecting groove 8.

[0027] The inner wall of the protective cover body 1 is provided with an internal thread 13, and the outer wall of the protective cover body 1 is provided with multiple anti-slip grooves 14. The anti-slip grooves 14 make it convenient for the user to rotate the protective cover body 1. The internal thread 13 allows the protective cover body 1 to be screwed onto the external thread on the outside of the blood concentrator connector.

[0028] The protective cover body 1 and the sealing plug 2 are both made of PP material. The protective cover body 1 and the sealing plug 2 are processed by injection molding separately and then assembled after processing.

[0029] Working principle of this utility model:

[0030] When using this device, place the protective cover body 1 at one end of the blood concentrator connector and insert its sealing plug 2 into the blood concentrator connector. Then rotate the protective cover body 1 so that it is screwed onto the blood concentrator connector through the internal thread 13. During this process, the sealing plug 2 is inserted into the blood concentrator connector. The sealing plug 2 and the protective cover body 1 cooperate to achieve the wrapping protection of the blood concentrator connector.

[0031] During the insertion of the sealing plug 2 into the blood concentrator connector, its conical structure design increases the contact area between the sealing plug 2 and the inner wall of the blood concentrator connector. Furthermore, as the thicker end of the sealing plug 2 is inserted, the sealing plug 2 is deformed by the pressure of the inner wall of the blood concentrator connector. During the deformation process, the supporting rib 4 guides the deformation of the sealing plug 2, causing the sealing plug 2 to collapse from the outside to the inside. After the collapse deformation, the sealing plug 2 can continue to be inserted into the blood concentrator connector and fill the inside of the blood concentrator connector, thereby improving its sealing effect.

[0032] Before and after use, the sealing plug 2 can be pulled to move the connecting block 9, so that the connecting block 9 can be pulled out from the connecting groove 8, thereby separating the protective cover body 1 and the sealing plug 2, so that the protective cover body 1 and the sealing plug 2 can be disinfected and cleaned separately.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
