Description

Technical Field

[0001] This invention relates to the field of umbilical cord ligation, and more specifically to an umbilical cord ligation device. Background Technology

[0002] After the baby is born, the umbilical cord needs to be tied off to prevent infection.

[0003] In existing technologies, umbilical cord clamps and valve cores are commonly used for ligation.

[0004] The umbilical cord clamp method leaves a piece of the umbilical cord clipped to the baby's belly after use. However, because a baby's skin is very delicate, and the plastic umbilical cord clamp is relatively hard, it can stick tightly under gravity and easily scratch the skin. Furthermore, swimming is a common postpartum training method for infants both domestically and internationally. After swimming, the body needs to be wiped down and clothes changed, and having a large and heavy foreign object attached to the umbilical cord is inconvenient.

[0005] The valve core ligation method requires manually placing the valve core onto a hemostat, clamping the umbilical cord with the hemostat, and then pulling the valve core through the suture to secure it to the umbilical cord. The valve core is usually a rubber ring, and to ensure the suture can pull the valve core, the contraction force of the valve core should not be too great, which could lead to the risk of blood splattering. Summary of the Invention

[0006] The present invention aims to provide an umbilical cord ligation device that can both prevent the umbilical cord clamp from scratching the skin and reduce the risk of blood splattering.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an umbilical cord ligation device, comprising an umbilical cord clamp and two clamping plates, the umbilical cord clamp comprising two clamping arms, one end of the two clamping arms being rotatably connected, the other end of the two clamping arms being snapped together, each clamping arm being rotatably connected to at least one rotating cylinder, the clamping arm passing through the rotating cylinder along its length; the clamping plates clamping the umbilical cord on both sides, the clamping arms clamping the clamping plates and providing pressure to the clamping plates, the clamping plates passing through the space between the two clamping arms;

[0008] The clamp plate has a receiving area. After pulling the valve core into the receiving area, push the clamp arm on the clamp plate to move away from the navel. After the clamp arm passes the receiving area, continue to pull the valve core to the end of the umbilical cord.

[0009] The core idea of ​​this approach is to use both valve core and umbilical cord clamp for ligation. Initially, the umbilical cord clamp plays a primary role. After a period of time, once the risk of blood splattering decreases, the umbilical cord clamp is removed first to avoid scratching the skin. In the later stages, the valve core plays a primary role.

[0010] The core idea raises the following issue: Since the umbilical cord clamp is mainly used to prevent blood from splashing out in the early stages, it is necessary to clamp the umbilical cord tightly before cutting it. However, due to the presence of the umbilical cord clamp, it is impossible to pull the valve core to the end of the umbilical cord closest to the navel, which can easily lead to the valve core loosening. Especially after the umbilical cord clamp is removed in the later stages, the umbilical cord between the valve core and the navel will wobble, further increasing the risk of the valve core loosening.

[0011] This solution improves the umbilical cord clamp by adding a rotating cylinder to the clamp arm and a clamping plate between the clamp arm and the umbilical cord. This allows the umbilical cord clamp to move on the clamping plate after clamping the umbilical cord. The two clamping plates can then pass through the valve core, allowing the valve core to reach the end of the umbilical cord through the clamping position. Specifically, the umbilical cord clamp is held in place by the clamping plate, with the receiving area located on the side of the clamp away from the navel. One end of the clamping plate is located at the end of the umbilical cord, and the other end passes through the umbilical cord clamp, leaving space for upward movement of the clamp to facilitate its passage through the receiving area. Excess umbilical cord is cut off, and the thread is threaded through the valve core. The valve core is then placed on the two clamping plates, and the thread pulls the valve core to the receiving area, pushing the clamp arm through the receiving area. The thread continues to pull the valve core to the end of the umbilical cord, pushing the umbilical cord clamp closer to the navel.

[0012] Furthermore, the receiving area is a strip-shaped groove on the clamp plate, which is used to receive the valve core and ensure that the cylinder passes through smoothly.

[0013] Furthermore, the clamping plate is long and narrow, with strip-shaped protrusions along its length; the rotating drum has circumferential grooves that cooperate with the strip-shaped protrusions.

[0014] Furthermore, the two clamps are curved on opposite sides.

[0015] Furthermore, it also includes a docking device, which includes an outer cylinder, an inner rod inside the outer cylinder, a valve core sleeved on the inner rod, a wire threaded inside the valve core, the wire being used to pull the valve core to slide on the inner rod, and a gripper at the lower end of the inner rod.

[0016] In the initial state, the grippers are open and extend from the lower end of the outer cylinder;

[0017] The inner rod moves upward relative to the outer cylinder, and the lower end of the outer cylinder pushes the gripper inward to grip the upper part of the two clamping plates. The wire pulls the valve core to slide over the gripper.

[0018] Furthermore, the outer cylinder has a vertical strip-shaped notch on its side, with the lower end of the strip-shaped notch penetrating the bottom of the outer cylinder;

[0019] When the wire pulls the valve core, the wire passes through the strip-shaped notch.

[0020] Furthermore, the upper end of the inner rod extends through the upper end of the outer cylinder and has an end head, the radius of which is larger than the inner diameter of the outer cylinder; the upper part of the inner rod and the inner side of the outer cylinder are threaded together.

[0021] Furthermore, the inner rod includes an upper inner rod and a lower inner rod that are threaded together. The upper inner rod is threaded to the inner side of the outer cylinder. The outer diameter of the lower inner rod is smaller than that of the upper inner rod. The valve core is fitted onto the lower inner rod.

[0022] Furthermore, a linear motor is installed at the upper end of the outer cylinder, and the output shaft of the linear motor is connected to the upper end of the inner rod.

[0023] Furthermore, the gripper includes several circumferentially arranged elastic rods, the upper ends of which are all connected to the lower ends of the inner rods, and the elastic rods are provided with at least one inward bend.

[0024] This solution also has the following effects:

[0025] 1. The strip-shaped protrusions and circumferential grooves work together to guide the movement of the rotating drum, preventing the clamping plate from tilting and reducing the clamping effect, thus avoiding blood splattering.

[0026] 2. The two clamps are curved on opposite sides to facilitate fitting the umbilical cord surface. Since the umbilical cord clamps will be removed in advance, and the valve core will mainly play a ligation role later, there is no need to worry about the curved cross section not clamping tightly after the umbilical cord shrinks.

[0027] 3. The connector is mainly used to facilitate the installation of valve cores. Multiple valve cores can be pre-fitted onto the inner rod of the connector to increase operational efficiency. A strip-shaped notch is set on the outer cylinder to ensure smooth pulling of the wire, further increasing operational efficiency.

[0028] 4. After cutting the umbilical cord, push the clamps through the outer cylinder to grip the umbilical cord and the two clamps, completing the docking of the docking device and the clamps; after the clamps are clamped, the outer diameter of the clamps decreases so that the valve core can pass through the clamps, thereby allowing the valve core to be fitted onto the two clamps.

[0044] Example 1

[0045] Example 1 is basically as follows Figures 1-11 As shown: An umbilical cord ligation device includes an umbilical cord clamp 1, a connector 2, and two clamping plates 3;

[0046] like Figure 1 As shown, the umbilical cord clamp 1 includes a U-shaped portion 11 and two clamping arms. The left ends of both clamping arms are connected to the U-shaped portion 11. The U-shaped portion 11 is made of elastic material. Under the action of external force, the U-shaped portion 11 can drive the left ends of the two clamping arms to rotate relative to each other. The other ends of the two clamping arms are engaged in the same way as the umbilical cord clamp 1 in the prior art. Figure 1 The snap-fit ​​method in the diagram is a simplified illustration. One of the clamping arms has a snap-fit ​​component 13 integrally formed on the right end, and the other clamping arm has a slot component 14 integrally formed on the right end. The snap-fit ​​component 13 is used to snap-fit ​​with the slot component 14.

[0047] Both clamping arms include two rotating shafts (the rotating shafts are internal structures and are not shown in the figure). The left end of each rotating shaft is integrally formed with the U-shaped part 11, and the right end of each rotating shaft is integrally formed with the buckle part 13 or the slot part 14. A rotating cylinder 12 is rotatably connected to each rotating shaft, and the rotating shaft passes through the rotating cylinder 12 along the length direction of the rotating cylinder 12.

[0048] Two clamping plates 3 are used to hold the umbilical cord 4. The clamping arms are clamped on the clamping plates 3 and provide pressure to the clamping plates 3. The clamping plates 3 are all long strips. The two clamping plates 3 are arc-shaped on opposite sides. The width of the clamping plates 3 is less than the length of the rotating cylinder 12. The two clamping plates 3 pass between the rotating cylinder 12 of the two clamping arms. The clamping plates 3 are perpendicular to the rotating cylinder 12. A strip-shaped groove 31 is provided in the middle of the clamping plate 3 along the width direction. The strip-shaped groove 31 is the receiving area for accommodating the valve core 5.

[0049] like Figure 2 , Figure 3 , Figure 4 As shown, the docking device 2 includes an outer cylinder 21. The outer cylinder 21 has a vertical strip-shaped notch 22 on its side, and the lower end of the strip-shaped notch 22 penetrates the bottom of the outer cylinder 21. An inner rod is inserted inside the outer cylinder 21. The inner rod includes an upper inner rod 23 and a lower inner rod 24 that are threaded together. The upper inner rod 23 is threaded to the inner side of the outer cylinder 21. The outer diameter of the lower inner rod 24 is smaller than the outer diameter of the upper inner rod 23. Several valve cores 5 are fitted on the upper inner rod 23. Each valve core 5 has a thread 25 inserted inside it. The upper end of the upper inner rod 23 extends out of the upper end of the outer cylinder 21 and is integrally formed with an end 26. The radius of the end 26 is larger than the inner diameter of the outer cylinder 21. The upper inner rod 23 is threaded to the inner side of the outer cylinder 21. The lower end of the lower inner rod 24 is provided with a gripper 27. The gripper 27 includes several elastic rods arranged circumferentially. The upper end of each elastic rod is integrally formed with the lower end of the inner rod. The elastic rod has an inward bend, and the side closer to the circle is the inner side.

[0050] The wire 25 is used to pull the valve core 5 to slide on the lower inner rod 24 and the clamping plate 3;

[0051] In this embodiment, the method of using an umbilical cord ligation device is as follows:

[0052] 1. For example Figure 5 As shown, the lower end of the umbilical cord 4 is close to the navel. The umbilical cord clamp 1 clamps the umbilical cord 4 through the clamp plate 3. The receiving area on the clamp plate 3 is located on the upper side of the clamp plate 3. The lower end of the clamp plate 3 is located at the end of the umbilical cord 4. After passing through the umbilical cord clamp 1, space is reserved for the upward movement of the umbilical cord clamp 1 so that the umbilical cord clamp 1 can pass smoothly through the receiving area.

[0053] 2. For example Figure 6 As shown, cut off the excess umbilical cord 4;

[0054] 3. For example Figure 7As shown, the docking device 2 is aligned with the cut end of the umbilical cord 4. In the initial state, the grippers 27 are open and extend from the lower end of the outer cylinder 21.

[0055] 4. For example Figure 8 As shown, hold end 26 and rotate outer cylinder 21 to move outer cylinder 21 downward relative to inner rod. The lower end of outer cylinder 21 pushes gripper 27 inward to grip the upper end of two clamping plates 3.

[0056] 5. For example Figure 9 As shown, the wire 25 of the lowest valve core 5 is pulled up, so that the wire 25 passes through the strip notch 22. The wire 25 pulls the valve core 5 to slide past the lower inner rod 24 and the clamp 27, and finally slides into the receiving area on the clamping plate 3;

[0057] 6. For example Figure 10 As shown, loosen the thread 25, push the umbilical cord clamp 1 to slide upward on the clamp 3 until the umbilical cord clamp 1 passes through the receiving area, and pull the thread 25 to completely pass through the gap between the two clamp arms.

[0058] 7. For example Figure 11 As shown, continue pulling the valve core 5 to the end of the umbilical cord 4, and push the umbilical cord clamp 1 to slide downward on the clamping plate 3 to the limit position. In this embodiment, the limit position refers to the contact between the umbilical cord clamp 1 and the valve core 5.

[0059] Example 2

[0060] Example 2 is based on Example 1: as follows Figure 12 , Figure 13 As shown, the outer side of the clamping plate 3 is integrally formed with strip-shaped protrusions 32 along its length; the rotating cylinder 12 is provided with circumferential grooves that cooperate with the strip-shaped protrusions 32.

[0061] In step one of the method of using an umbilical cord ligation device, the strip protrusion 32 and the circumferential groove are aligned and cooperate with each other.

[0062] Example 3

[0063] The difference between Embodiment 3 and Embodiment 1 is that Embodiment 3 also includes a linear motor, which is bolted to the upper end of the outer cylinder 21. The lower end of the output shaft of the linear motor is bolted to the upper end of the inner rod, and the inner rod is vertically slidably disposed inside the outer cylinder 21.
