Description

Catheter seat

The present invention relates to the technique of splitting, and in particular to a catheter hub.

Some cartridges add a float to a hollow housing and seal the housing opening with an upper cover. A tube is inserted into the lid to direct some of the liquid into the housing, such as oil. A linkage rod is coupled to the bottom of the upper cover and can be pushed by the floating float of the liquid to block the nozzle to prevent the liquid from continuing to flow into the housing for storage.

When the liquid is injected into the casing, not only the flow rate is large, but also the speed is fast, and a lot of air bubbles are generated in the liquid in the impact cylinder, causing the liquid surface to fluctuate, and the floating ring is substantially inclined with respect to the casing, and the contact linkage rod blocks the nozzle in advance, so that the storage is performed. The amount is lower than expected.

Therefore, how to reduce the probability of occurrence of clogging in advance becomes an urgent problem to be solved by the present invention.

In view of this, the main purpose of the present invention is to adopt a shunting structure to buffer the liquid injected into the storage cylinder, slow down the fluctuation of the liquid surface, improve the disadvantage of the tilt of the floating ring, and reduce the probability of clogging in advance.

Due to the above object, the catheter hub of the present invention comprises: a body and a shunt disk. The body has an input end, an output end and a connection input, The flow path at the output. The splitter disc has at least one rib, and when the splitter disc is coupled to the body, a plurality of outlets are formed by the rib engaging output end.

In this way, the body directs liquid to flow from the input end to the output end, and the shunt disk is subjected to the momentum of the flow. Moreover, the flow rate of the liquid separated by the ribs to the outlet is small, the flow rate is slow, and the liquid can flow down the wall of the cylinder, so that the liquid accumulated in the storage cylinder does not generate excessive bubbles, and the fluctuation of the liquid surface is relatively slowed down, so that the floating ring stays close. In the horizontal state, the probability of clogging in advance is reduced.

In some catheter adapters, the diverter disc has at least one diverting orifice extending through the diverter disc adjacent to the rib to share the local flow of liquid.

Figure 5 is a perspective view of a second embodiment of the catheter hub of the present invention.

Referring to Figures 1 through 3, a specific configuration of the first embodiment of the catheter hub 10 is illustrated. The body 11 is comprised of a body 11 and a shunt plate 20 for coupling to one end of the tube 19.

The body 11 has an input end 12 and an output end 13. The input end 12 and the output end 13 are connected by a main channel 14. The back of the body 11 has a protruding connecting portion 17, and the connecting portion 17 is inserted into one end of the tube 19. The body 11 also has a pair of fastening portions 18, and these fastening portions 18 is generally a hook body, the root of which is designed to be integral with the output end 13 of the body 11.

The flow channel 14 distinguishes between the large and small diameter segments 15, 16: the large diameter segment 15 extends from the input end 12 toward the output end 13, the small diameter segment 16 is formed at the center of the connecting portion 17, and the two diameter segments 15, 16 are mutually The same.

The shunt plate 20 has a substantially conical shape with two notches 23 formed at the edges thereof, and the notches 23 are located at the two ends of the diameter. The splitter disk 20 has four split holes 21 and two ribs 22 which are entangled with each other on the surface of the splitter disk 20 such that each of the split holes 21 penetrates the splitter disk 20 and is located beside the ribs 22.

The notch 23 is aligned with the engaging portion 18, and the shunting disk 20 is pressed against the body 11, so that the notch 23 receives the engaging portion 18, and the engaging portion 18 catches the periphery of the notch 23, so that the shunting disk 20 is combined with the body 11 to form the catheter hub 10. At the same time, the rib 22 contacts the output end 13 of the body 11 to form four outlets 24, preventing the shunt disc 20 from moving along the length of the engaging portion 18.

As shown in Figures 3 and 4, the catheter hub 10 is coupled to the upper cover 36. The body 11 directs the liquid to flow from the input end 12 to the output end 13 and impacts the splitter disk 20 to be separated by the ribs 22, and flows to the outlet 24 in the direction of the horizontal arrow of FIG. 4, which not only has a small flow rate, a slow flow rate, but also follows the inside of the storage cylinder 30. Under the wall flow, the stored liquid 32 does not cause excessive bubbles, which relatively slows the fluctuation of the liquid surface. The floating ring 34 rising in the direction of the vertical arrow in FIG. 4 maintains a horizontal state, avoiding the linkage rod 38 that is engaged with the bottom of the upper cover 36, and reduces the probability of clogging in advance.

Wherein, the center of the shunt disk 20 facing the one side of the body 11 is higher than the periphery, and the guiding action is more effective when the force of the liquid flow is received. Further, each of the orifices 21 shares the partial flow rate of the liquid 32, and flows into the inside of the storage cylinder 30 in the direction of water droplets in the fourth drawing.

In Fig. 5, a second embodiment of the catheter adapter 10 is shown which differs from the first embodiment in that the rib 22 is designed in one piece with the output end 13 without affecting the shunting effect of the respective outlets 24.
