Figure 3 is a schematic diagram of the structure of the conduit. Refer to Figure 3. The conduit 1 includes a conduit body 12. The conduit body 12 has openings at both ends. The diameter of the top opening of the conduit body is larger than the diameter of the bottom opening. The inner wall of the top end of the conduit body 12 is provided with a locking glue. Ring 11, the inner wall of the bottom end of the catheter body 12 is provided with a catheter positioning rubber ring 13, and the catheter positioning rubber ring 13 is placed on the auxiliary tube positioning rubber ring 52.

The clamping rubber ring 11 is made of silicone or rubber. The clamping rubber ring 11 is placed above the clamping protrusion 21 on the outer wall of the funnel module 2, and is blocked by the clamping protrusion 21, so that the funnel module The funnel cup body 22 is in a tightened state. The diameter of the locking rubber ring 11 is smaller than the cross-sectional diameter at the locking protrusion 21 after the funnel cup body 22 is opened. The locking rubber ring 11 can constrain the funnel cup body 22 to shrink the opening part, so that the stored product can be Easily push it into the vagina. The locking rubber ring 11 cooperates with the locking protrusion 21 so that the funnel module 2 will not slide down during assembly. However, after a certain force is applied, the catheter 1 can slide down and the funnel module 2 will slide down. After the catheter 1 is stretched out, it is fully opened and restored to its original state.

The material of the catheter body 12 can be paper materials such as waxed paper, parchment paper, cellophane, or other plastic materials such as DPE, PVC, OPP, or aluminum foil, composite plastic, paper-plastic composite materials, etc. Since the funnel module 2 is placed in the conduit 1, the conduit 1 can not only connect the funnel module 2 and the auxiliary pipe 5 before use, but also protect the funnel module. During use, the conduit 1 acts as a force to move the blocking rubber ring 11 from above the blocking protrusion 21 to below, thereby separating the conduit from the funnel module.

The catheter positioning rubber ring 13 is made of silicone or rubber and is used for positioning and moving the clamping rubber ring 11 downward along with the catheter. The inner diameter of the catheter positioning rubber ring 13 is slightly smaller than the outer diameter of the auxiliary tube positioning rubber ring 52, and the edges are rounded. The catheter positioning rubber ring 13 is placed on the auxiliary tube positioning rubber ring 52. When dismantling, you need to pinch the auxiliary tube to position it. By pulling down the rubber ring 52 with a certain force, the catheter positioning rubber ring 13 can be removed from the auxiliary tube positioning rubber ring 52 . The catheter positioning rubber ring 13 and the auxiliary tube positioning rubber ring 52 simultaneously play the role of positioning the depth of the vagina.

The upper outer wall of the funnel cup body 22 is provided with a circle of latching protrusions that match the latching rubber ring 11. 21, the bottom end of the drain pipe 24 is provided with a liquid-dispersed cage 23.

The funnel cup body 22 is made of silicone or rubber with moderate hardness and has good stretchability. It is in a tightened state before the catheter is removed. Due to the moderate hardness, the mouth of the funnel cup body 22 will shrink under the action of the catheter. Part of it can quickly return to its original shape after the catheter is pulled off. The edge of the cup opening of the funnel cup body 22 is rounded so that it will not cause damage to the skin of the inner wall of the vagina. After unfolding, it fits the inner wall of the vagina. Due to the difference in internal and external air pressure, it can be tightly sucked and will not fall off easily. Its function is to catch the menstrual blood flowing down from the uterus and introduce the menstrual blood into the blood storage bottle 3 .

The retaining protrusion 21 is an annular protrusion provided on the outer wall of the funnel cup body 22 and is integrally formed with the funnel cup body. Its function is to cooperate with the positioning rubber ring on the conduit 1 to prevent the funnel cup body from collapsing when it is contracted. decline.

The dispersing liquid cage 23 is made of hard plastic and clamps the end of the drain pipe of the funnel cup body. The size is slightly larger than the drain pipe and is surrounded by a hollowed-out fence. Its function is to ensure that menstrual blood can flow into the blood storage bottle 3. Since the water-absorbing body 4 will expand after absorbing blood, if there is no liquid-dispersing cage, there may be a certain probability that the outlet hole of the drain pipe will be blocked, resulting in poor drainage.

Figure 5 shows a schematic structural diagram of the blood storage bottle. Refer to Figure 5. The blood storage bottle 3 includes a bottle body 32. The bottle body 32 is made of silicone or rubber and has high stretchability. Even if the water-absorbing body 4 absorbs water, its volume expands several times. It won't break. The top of the bottle body 32 is provided with 2-4 exhaust holes 31 with a diameter of 1-2 mm. The function of the exhaust holes 31 is to form a closed space after the funnel cup body and the vaginal wall fit, and the water-absorbent body 4 absorbs water. The volume expands and occupies the space of the blood storage bottle. If there is no vent hole, the positive air pressure will prevent the blood from flowing down and cause backflow. At this time, the excess gas needs to be discharged from the hole.

A drawstring 33 is provided on the bottom outer wall of the blood storage bottle 3. The drawstring is made of nylon or other high-strength fibers and is connected to the bottom of the blood storage bottle and cannot be disassembled.

The tube body 51 can be removed from the blood storage bottle 3 and discarded. The nylon drawstring 33 on the blood storage bottle 3 is placed inside the hollow auxiliary tube body when the product leaves the factory. After the auxiliary tube is pulled out, the nylon drawstring 33 will automatically come out of the tube.

However, the connection between the tube body 51 and the blood storage bottle 3 is not limited to threaded connection, and other methods can be used. For example, a star gear clamping position can be provided on the top of the tube body 51, and the tube body 51 is connected to the connecting column on the outer wall of the bottom end of the blood storage bottle 3 through the star gear clamping position, so that it can be stuck at a specific position and not easily pulled down, and can be pulled down after rotating a certain angle, and then pulled out from the blood storage bottle 3 and discarded.

The auxiliary tube positioning rubber ring 52 is made of silicone or rubber, has a rough surface and fine lines, and is used to enhance friction. The auxiliary tube positioning rubber ring 52 is not inserted into the vagina. Its function is to cooperate with the positioning rubber ring below the catheter to fix the catheter 1 so that it is not easy to loosen, and this position also serves to remind the user to extend into the vagina. The cup body has reached the ideal position.
