Description

Technical Field

[0001] The utility model relates to the technical field of umbilical cord clamps, in particular to an umbilical cord clamp capable of clamping at multiple angles. Background Art

[0002] In medical practice, especially after the birth of a newborn, the handling of the umbilical cord is a key step. The umbilical cord clamp avoids the problems of complicated operation and easy falling off that may be caused by traditional ligatures or bandages. Umbilical cord clamps are usually made of plastic, metal or other medical materials. The umbilical cord clamps on the market often have only two clamping blocks, which clamp the umbilical cord from two directions. After the two sides of the umbilical cord are clamped, the deformed areas on both sides are located at the junction of the two clamping blocks, which will cause the two sides of the umbilical cord to be unable to be clamped. Since the clamping area is only on both sides, the clamping stability is poor, and the umbilical cord cannot be fully clamped, which also causes the umbilical cord to fall off slowly. Wearing the umbilical cord clamp for a long time also increases the risk of scratching the newborn. Utility Model Content

The middle clamp and the side clamp are located in the same plane, and the force on the umbilical cord is uniform during clamping, avoiding the formation of shear force on the umbilical cord, which can not only clamp more firmly, but also make the part where the umbilical cord falls off more flat.

[0022] Example 1

[0023] Please refer to the attached Figures 1 to 3The present application provides an umbilical cord clamp with multi-angle clamping, including an arc-shaped middle clamping block 1 and a side clamping block 2. The first ends of the two side clamping blocks 2 are respectively hinged to the two ends of the middle clamping block 1, and the second ends of the two side clamping blocks 2 are connected to each other through a clamping piece. The second ends of the side clamping blocks 2 are connected by the clamping piece. The middle clamping block 1 and the side clamping block 2 clamp the umbilical cord from the periphery, which not only improves the stability of clamping, but also the clamping block applies clamping force to the umbilical cord from three directions, which can make the umbilical cord fall off faster. The edges of the middle clamping block 1 and the side clamping block 2 are both smoothly transitioned, and the smooth transition can prevent the edges of the clamping blocks from scratching the newborn. The middle clamping block 1 and the side clamping block 2 are located in the same plane. The force on the umbilical cord is uniform during clamping, avoiding the formation of shear force on the umbilical cord, which can not only clamp more firmly, but also make the part where the umbilical cord falls off more flat. The gap between the inner side surfaces of the middle clamp block 1 and the side clamp block 2 is provided with an elastic arc-shaped piece 3, one end of the arc-shaped piece 3 is fixedly connected to the middle clamp block 1 or the side clamp block 2, and the other end is inserted into the groove 4 provided in the adjacent middle clamp block 1 or the side clamp block 2. When the side clamp block 2 moves toward the middle to clamp the umbilical cord, the arc-shaped piece 3 slides into the groove 4. The arc-shaped piece 3 can fill the gap between the junction of the middle clamp block 1 and the side clamp block 2, so that the umbilical cord is clamped all around, that is, the stability of the clamping is improved, and the umbilical cord can also be made to fall off faster. Under the elastic force of the arc-shaped piece 3, the middle clamp block 1 and the side clamp block 2 are opened, which is convenient for medical staff to put the umbilical cord clamp on the umbilical cord and facilitate the operation of medical staff. The arc-shaped piece 3 is inserted into the groove 4 after the umbilical cord clamp is closed, so that the contact surface between the umbilical cord clamp and the umbilical cord is flat, which can make the umbilical cord bear force all around.

[0024] In the utility model, the second ends of the two side clamps 2 are separated in the initial state, and the two side clamps 2 are separated under the action of the arc-shaped piece 3, which makes it convenient for medical staff to put the umbilical cord between the two side clamps 2. After the umbilical cord clamp is placed in a suitable position, the two side clamps 2 are rotated toward the middle, and the second ends of the side clamps 2 are connected by clamping. When the side clamps 2 are rotated toward the middle, the arc-shaped piece 3 can enter the groove 4, and finally the middle clamp 1, the side clamp 2 and the arc-shaped piece 3 clamp the umbilical cord clamp from all sides. The umbilical cord can be clamped in multiple directions, and the clamping stability is high, which increases the speed of the umbilical cord falling off and reduces the risk of scratching the newborn.

[0025] Optionally, the middle clamp block 1 and the side clamp block 2 are provided with a receiving groove 5, the depth of the receiving groove 5 is the same as the thickness of the arc-shaped piece 3, the receiving groove 5 is connected to the fixed end of the arc-shaped piece 3 or to the groove 4, and the arc-shaped piece 3 located on the inner side of the middle clamp block 1 and the side clamp block 2 is placed in the receiving groove 5. The part of the arc rod that does not extend into the groove 4 is placed in the receiving groove 5, and the side of the arc-shaped piece 3 is flush with the inner side wall of the clamp block, so that multiple surfaces can contact the umbilical cord when clamping the umbilical cord, the force on all sides of the umbilical cord is more even, the clamping is more stable, and the umbilical cord is facilitated to fall off.

[0026] Specifically, the clamping member includes a clamping protrusion 6 and a clamping groove 7, wherein one of the side clamping blocks 2 is provided with the clamping protrusion 6, and the other side clamping block 2 is provided with the clamping groove 7, and the clamping protrusion 6 is used to be inserted into the clamping groove 7. The two side clamping blocks 2 are pushed to move closer to the middle, and then the clamping protrusion 6 is clamped into the clamping groove 7, so that the clamping protrusion 6 and the clamping groove 7 cooperate to clamp the umbilical cord tightly between the two side clamping blocks 2 and the middle clamping block 1. Preferably, a plurality of clamping grooves 7 can be provided, and the clamping protrusion 6 is clamped into the corresponding clamping groove 7 according to the diameter of the umbilical cord and the required clamping force. Optionally, the middle clamping block 1 and the side clamping block 2 are made of elastic plastic to facilitate the connection of the clamping member.

[0027] Example 2

[0028] Please refer to the attached Figure 4 The difference between this embodiment and the first embodiment is that the clamping member includes a connecting belt 8, a hook 9, a groove 10 and an elastic member 11. One end of the connecting belt 8 is connected to the elastic member 11, and the other end is connected to the hook 9. The elastic member 11 is connected to one of the side clamps 2. The other side clamp 2 is provided with a plurality of grooves 10. The hook 9 is matched and connected with the grooves 10. The elastic member 11 is used to drive the connecting belt 8 away from the grooves 10. The hook 9 on the connecting belt 8 is hooked in the groove 10 so that the two side clamps 2 clamp the umbilical cord toward the middle. One end of the connecting belt 8 is connected to the elastic member 11. The elastic member 11 can be a spring or other elastic member or mechanism. Under the action of the elastic member 11, the connecting belt 8 is tightened. When the umbilical cord gradually shrivels during the shedding process, the elastic member 11 pulls the two side clamps 2 to continue to gradually approach the middle, thereby maintaining the clamping force.

[0029] Example 3

[0030] Please refer to the attached Figure 5 In this embodiment and embodiment 2, the elastic member 11 includes a reel 12 and a torsion spring 13. The reel 12 is rotatably connected to the side clamp block 2. One end of the torsion spring 13 is connected to the reel 12, and the other end is connected to the side clamp block 2. The connecting belt 8 is connected to the reel 12, and the torsion spring 13 drives the reel 12 to rotate to reel the connecting belt 8. The torsion spring 13 drives the reel 12 to rotate to reel the connecting belt 8, thereby pulling the two side clamp blocks 2 to move toward the middle to clamp the umbilical cord. The torsion spring 13 can provide a stable elastic force to drive the connecting belt 8 to drive the side clamp blocks 2 to clamp the umbilical cord.

[0031] Optionally, a cam 14 is provided on the side of the reel 12, and the outer contour line of the cam 14 is a plane spiral line, so the angles of the tangent of the contour line of the cam 14 are different at different positions. The side clamp 2 is provided with a spring sheet 15, and the middle part of the spring sheet 15 is provided with a protrusion abutting against the cam 14. The spring sheet 15 pushes the cam 14 to drive the reel 12 to release the connecting belt 8. The protrusion on the spring sheet 15 is pressed on the cam 14, and the direction of the force of the protrusion on the cam 14 is perpendicular to the tangent direction of the contour line. Therefore, the force can be decomposed into a first component toward the rotation center of the cam 14 and a second component perpendicular to the first component. The second component produces the effect of driving the cam 14 to rotate. When the end with a larger diameter of the cam 14 turns to the spring sheet 15, the spring sheet 15 is gradually compressed, and the thrust of the spring sheet 15 also gradually increases, and the component that pushes the cam 14 to rotate also gradually increases. When the reel 12 releases the connecting belt 8, the end of the cam 14 with a larger diameter turns to the spring sheet 15. When the connecting belt 8 is released, the torsion spring 13 is compressed, resulting in an increase in the tension of the connecting belt 8, and the spring sheet 15 is also compressed, which increases the force of the reel 12 to release it. Therefore, the spring sheet 15 can reduce the change in the tension of the connecting belt 8 caused by the compression of the torsion spring 13. The torsion spring 13 of the utility model has a certain preload force. The tension of the connecting belt 8 changes very little or remains unchanged when it is pulled out. The retraction of the connecting belt 8 is the reverse process of the pulling out. Therefore, during the retraction of the connecting belt 8, the tension of the connecting belt 8 remains unchanged or changes very little. After the connecting belt 8 is fastened, the outer diameter decreases as the umbilical cord shrivels during the shedding process. At this time, the connecting belt 8 pulls the two side clamps to continue to move closer to the middle and clamp. During the clamping process, the clamping force will not be reduced due to the release of the elastic force of the torsion spring 13. The utility model sets the clamping force in the initial state, and can maintain the stability of the clamping force during the shedding process of the umbilical cord.

[0032] Specifically, two ends of the spring sheet 15 are bent inward to form a U-shaped structure 16, and the U-shaped structure 16 is fixedly connected to the side clamp block 2. The spring sheet 15 maintains a stable elastic force to push the cam 14.

[0033] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
