[0023] The following will describe in more detail a hemodialysis tube connector protection cap and a hemodialysis tube of the present utility model with reference to the drawings, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad knowledge for those skilled in the art and not as a limitation to the present utility model.

[0024] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the drawings. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0025] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a convenient and practical protective cap for a hemodialysis tube joint 4, which includes a cap body 1, a disinfection member 2 and a sealing member 3.

[0026] Specifically, the disinfection member 2 is installed inside the cap body 1; the sealing member 3 is arranged at one end of the cap body 1; a cross-shaped opening 30 is provided on the sealing member 3; internal threads 10 are provided on the inner wall of the cap body 1 for threaded connection with the joint 4 of the hemodialysis tube; the threads 10 are located between the sealing member 3 and the disinfection member 2 and are close to the disinfection member 2.

[0027] Among them, the cap body 1 has a T-shaped structure. The sealing member 3 is placed at the end with a larger diameter of the T-shaped structure, and the disinfection member 2 is placed at the end with a smaller diameter of the T-shaped structure. The threads 10 are also arranged in the part with a smaller diameter of the T-shaped structure, so as to facilitate threaded connection with the joint 4 of the hemodialysis tube.

[0028] In this embodiment, the sealing member 3 is made of elastic rubber or silica gel.

[0029] Furthermore, the sealing member 3 and the cap body 1 are integrally formed.

[0030] In a specific example, continue to refer to Figure 2 As shown in the figure, the width dimension of the cross-shaped opening 30 is between 0.3 - 1 mm. The length dimension of the cross-shaped opening 30 is between 2 - 3.5 cm. The size of the cross-shaped opening 30 can be set according to actual needs.

[0031] When the joint 4 passes through the cross-shaped opening 30, due to the elastic adsorption characteristic of the cross-shaped opening 30, it can adsorb the side wall of the joint 4, which can ensure the airtightness inside the cap body 1, thereby preventing foreign impurities from entering and contaminating the hemodialysis tube.

[0032] In this embodiment, the cap body 1 is made of rubber or plastic.

[0033] In one embodiment, the disinfection member 2 is a disinfection cotton.

[0034] Furthermore, a placement space is provided inside the cap body 1. Specifically, the disinfection member 2 is located inside the placement space.

[0035] Among them, the size of the placement space is greater than or equal to the size of the disinfection cotton. The size of the placement space can be set according to actual needs, and the size should not be set too large to facilitate fixing the disinfection cotton.

[0036] In addition, a fixing member for fixing the disinfection cotton can be provided inside the placement space.

[0037] In one embodiment, the placement space is close to the thread 10. When the sterilizing cotton is placed in the placement space, it can just be close to the end of the thread 10. When the joint 4 of the hemodialysis tube enters the cap body 1, after the connection of the thread 10, the joint 4 can contact the sterilizing cotton, so as to disinfect the joint 4.

[0038] In addition, as Figure 3 shown, this embodiment also proposes a hemodialysis tube, which includes the protection cap of the hemodialysis tube joint 4 as described above, and also includes the joint 4. Specifically, a connecting thread 10 is provided on the side wall of the joint 4, and the joint 4 is threadedly connected to the protection cap of the hemodialysis tube joint 4 through the connecting thread 10.

[0039] A fixing member is provided in the cap body 1 for fixing the sterilizing member 2.

[0040] In this embodiment, the joint 4 of the hemodialysis tube is inserted into the cap body 1 through the cross-shaped opening 30 and threadedly connected to the cap body 1 until the joint 4 contacts the sterilizing cotton, so as to disinfect the joint 4.

[0041] In summary, a protection cap for a hemodialysis tube joint and a hemodialysis tube proposed by the present utility model have the following advantages:

[0042] Through the settings of the cap body, the sterilizing member and the sealing member; and the sterilizing member is installed in the cap body; the sealing member is provided at one end of the cap body; a cross-shaped opening is provided on the sealing member; the inner wall of the cap body is provided with a thread for threadedly connecting with the joint of the hemodialysis tube; the thread is located between the sealing member and the sterilizing member and is close to the sterilizing member. This device can effectively disinfect the joint of the hemodialysis tube and prevent external impurities from entering the hemodialysis tube and polluting it. In addition, through the adsorption of the side wall of the joint by the cross-shaped opening, the airtightness inside the cap body can be guaranteed, thereby avoiding the entry of external impurities and polluting the hemodialysis tube.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
