[0002] The hemodialysis catheter is a tube that connects the patient's blood vessels and the dialyzer. The blood comes out from the arterial end, passes through the dialyzer, and then returns to the patient's body from the venous end. In the process of connecting the dialysis instrument and the dialysis tube, a side hole connector is often needed to assist in the connection between the instrument and the tube.

[0003] However, the existing side hole joint only has a single sleeve. During the pipe docking process, it is necessary to pinch the sleeve body by hand and insert it into the docking instrument with force. The process is very laborious, and the sleeve body is prone to deformation and distortion, which brings great instability to the docking process. Therefore, a side hole joint with wings is designed.

[0024] In this embodiment, a side hole connector structure is provided, which is mainly used in hemodialysis and hemofiltration equipment. The design is made of rubber plastic material, such as Figure 1 , 2As shown in Figure 3, side wings are added on both sides of the connector body to provide a point of force for the knob when held. Compared with the existing simple connector body, the point of force for the hand-held part is increased, which is conducive to quick and effortless screwing in, brings convenience to the side hole docking process, and is more effective in terms of force. Specifically, through the structural setting of the side wings, under the structure of the side wing cross plate 311 and the side wing end plate 312, and through a number of reinforcing plates 313 arranged in an upper and lower array, structurally, on the one hand, the oblique edges where the reinforcing plates 313 are located provide convenience for the hand to exert force, and at the same time, under the connection of the several reinforcing plates 313, the strength of the side wings themselves is further enhanced, and they will not be twisted or deformed when force is applied.

[0025] Furthermore, a ring sleeve 112 is further provided at the connection position between the sleeve body 111 and the plug port 113. The ring sleeve 112 is embedded in the side wing end plate 312. Through the further arrangement of the ring sleeve 112, as shown in FIG. Figure 1 As shown, when the plug port 113 is docked with the hemodialysis or hemofiltration equipment, the ring sleeve 112 acts on the outside of the docking position of the plug port 113 to strengthen the clamping degree when the front end of the connector body is inserted.

[0026] Furthermore, the docking sleeve assembly includes a first end sleeve 411 , which is a sleeve structure without a cover and is not connected to the rear end of the sleeve body 111 .

[0027] like Figure 2 and 4 The first end sleeve 411 is a solid interface, which is used to connect to the outlet of the hemodialysis and hemofiltration equipment and play a blocking role.

[0028] Furthermore, a horizontal bar 412 is provided inside the first end sleeve 411, and the horizontal bar 412 forms a cross section with the inside of the first end sleeve 411, such as Figure 4 As shown, the structural strength of its tail is further improved.

[0029] Example 2

[0030] As another embodiment of the present utility model, the docking sleeve assembly further includes a second end sleeve 511 , and the second end sleeve 511 is connected to the rear end of the sleeve body 111 .

[0031] In this embodiment, another structure of the docking sleeve is provided, such as Figure 3 and Figure 5 As shown, the second end sleeve 511 is connected to the interior of the sleeve body 111 through the end through hole, and the second end sleeve 511 can also serve as a docking port for the next device, playing the role of an intermediate connector.

[0032] Example 3

[0033] As other embodiments of the utility model, the cap assembly includes a connecting portion 211 arranged on the plug-in port 113, the bottom of the connecting portion 211 is connected to a cover body 212, the front side of the cover body 212 is provided with an inner ring 214 and an outer ring 213 from the inside to the outside, and the outer ring 213 and the inner ring 214 form a docking groove 217 between the cover body 212 for plugging and adapting with the plug-in port 113.

[0034] By setting the cap assembly, such as Figure 1 , 2 As shown, the connection portion 211 is a flexible connection. In a normal non-use state, the cover body 212 covers the front end of the plug-in port 113. At this time, the inner ring 214 is located on the inner side of the plug-in port 113, and a damping is arranged between the two. The docking groove 217 acts on the end position of the plug-in port 113, and the outer ring 213 is covered on the outer wall of the plug-in port 113, thereby realizing the port closure of the sleeve 111.

[0035] Furthermore, the height of the inner ring 214 is greater than that of the outer ring 213, and a groove 218 is arranged in an annular shape on the outer wall of the inner ring 214. There are four grooves 218. Since the height of the inner ring 214 is greater than that of the outer ring 213, the inner ring 214 is built deeper inside the plug-in port 113, and has better sealing performance. At the same time, through the setting of the groove 218, the groove 218 and the arc-shaped contour of the inner ring 214 form a side reinforcement rib, and the middle position of the groove 218 is recessed inward, which further facilitates the docking of the inner ring 214 with the plug-in port 113.

[0036] Furthermore, the front end of the cover body 212 is provided with an extension portion 215, the extension portion 215 is in an arc cap shape, and a convex strip portion 216 is provided thereon. Figure 1 As shown, by providing the extension portion 215 and the convex strip portion 216 , the two constitute the hand-holding portion of the cover body 212 , providing convenience for opening the cover body 212 .
