[0038] See also Figures 1 to 13The present invention discloses a blood equipment connection structure, which includes: a base 1, a sleeve 2, a pipeline 3 and a Luer interface 4;

[0039] A target interface 11 is provided on one side of the base 1, and a first interface tube 121 and a second interface tube 122 are provided on the other side of the base 1. One end of the sleeve 2 is sleeved with the first interface tube 121, and the other end of the sleeve 2 is used to connect with an external device. The second interface tube 122 is connected to the pipeline 3, wherein the target interface 11 is connected to the first interface tube 121 and the second interface tube 122.

[0040] The target interface 11 is an interface designed specifically for a special interface on a specific target device, and the shape of the target interface 11 is adapted to the shape of the special interface on the target device. For example, in this embodiment, the target interface 11 includes two sub-interfaces 111 arranged in parallel. The shape of the target interface 11 is merely an example and is not intended to limit the present invention. Those skilled in the art may also configure the target interface 11 to have other shapes as needed to accommodate special interfaces of different shapes.

[0041] Specifically, in this embodiment, the interface of the sleeve 2 is designed as a Henkel interface so that it can be connected to an external Henkel interface. Furthermore, a sealing belt 21 is provided inside the sleeve 2 to ensure a sealing effect. The sealing belt 21 is a wavy or trapezoidal structure. A mounting handle 22 is provided on the outside of the sleeve 2. The provision of the mounting handle 22 facilitates the installation and tightening of the sleeve 2 by hand. Optionally, in this embodiment, the sleeve 2 is made of TPEE material and is injection molded. An installation mark 23 is provided at the other end of the sleeve 2. The installation mark 23 is used to align with the structure of the external structure itself during installation. Therefore, the position design of the installation mark 23 is based on the structure of the external structure itself. For example, in this embodiment, the installation mark 23 is two notches. Optionally, the installation mark 23 can also be a protruding structure or a marking line. The position where the sleeve 2 is connected to the first interface tube 121 is also provided with a first buckle 51.

[0042] Specifically, in this embodiment, the first interface pipe 121 is perpendicular to the base 1, and the second interface pipe 122 includes a vertical pipe 1221 perpendicular to the base 1 and an inclined pipe 1222 arranged at an angle to the vertical pipe 1221. The inclined pipe 1222 is connected to the vertical pipe 1221 and is inclined away from the first interface pipe 121. The other end of the inclined pipe 1222 is connected to the pipeline 3. More specifically, the axis of the first interface pipe 121 is perpendicular to the other side surface of the base 1, and the axis of the vertical pipe 1221 is perpendicular to the other side surface of the base 1. Due to the limited area of the base 1, the distance between the first interface pipe 121 and the second interface pipe 122 is relatively close. Therefore, the second interface pipe 122 is configured as a bent pipe to avoid interference.

[0043] Optionally, the pipeline 3 may be a hose.

[0044] Furthermore, a second buckle 52 is provided at the place where the pipeline 3 is connected to the second interface pipe 122 .

[0045] One end of the pipeline 3 away from the second interface tube 122 is provided with a Luer interface 4. The Luer interface 4 is a prior art and its specific structure is not described in detail.

[0046] A third buckle 53 is provided at the place where the pipeline 3 is connected to the Luer interface 4.

[0047] Optionally, in this embodiment, the first clip 51, the second clip 52 and the third clip 53 all include a clip body a, one end of the clip body a is provided with a through hole b, the other end of the clip body a is provided with a first leg c and a second leg d, the first leg c is provided with a protruding first snap-fitting portion e, the second leg d is provided with a second snap-fitting portion f, the first snap-fitting portion e is snap-fitted with the second snap-fitting portion f, and the through hole b is provided with a notch near one end of the first leg c and the second leg d. In this embodiment, the first engaging portion e is a protruding strip-like structure, and the second engaging portion f is a groove structure. The two sides of the strip-like structure that cooperate with the groove structure are configured in a ratchet-like manner to achieve the cooperation between the first engaging portion e and the second engaging portion f. Because the perforation b has a notch, the more the strip-like structure cooperates with the groove structure, the closer the first leg c and the second leg d are, and the smaller the diameter of the perforation b. Therefore, this type of buckle can accommodate structures of various diameters, similar to a cable tie structure that can tighten structures of various thicknesses. Optionally, the first buckle 51, the second buckle 52, and the third buckle 53 are all integrally molded plastic parts. A notch is provided on one end of the perforation b near the first leg c and the second leg d. In fact, the perforation b is configured as an open hole structure, and the closure of the perforation is achieved through the cooperation between the first buckle e and the second buckle f.

[0048] The present invention provides a blood equipment connection structure, in which the interface inside the sleeve 2 can be designed as a Henkel interface. Therefore, the blood equipment connection structure can integrate the Henkel interface and the Luer interface of the blood purification product dialysate. At the same time, the target interface 11 can realize the connection between the structure and the special interface of the target blood purification equipment, and be applied to the target scenario requirements, so as to break the technical barriers of imported brands and achieve domestic substitution.

[0049] like Figure 12 As shown, the present invention also discloses a blood purification device, which includes a filter 6 and two front blood equipment connection structures;

[0050] The sleeve 2 of each blood equipment connection structure is connected to the Henle port 61 of the filter 6, and the Luer port 4 of each blood equipment connection structure is connected to the Luer port 62 of the filter 6. The blood purification device has two target interfaces 11. The target interface 11 of each blood equipment connection structure is compatible with the corresponding interface on the hemodialysis machine (not shown). The blood purification device can be installed as a whole on the compatible hemodialysis machine. The modular design makes the application and installation of the blood purification device more convenient.

[0051] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
