Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

As shown in FIGS. 1 to 6 , an umbilical cord cutting device includes a base 5 , a cutting knife 4 , a clamp 2 and a clamping plate 3 .

Both sides of the base 5 are symmetrically provided with draw-in slots for positioning the clamps, and a horizontal spring hole is arranged on the base, and clamp springs 22 are arranged in the spring holes, and the two clamps are respectively arranged in the draw-in slots. , and the end of the clamp spring 22 abuts against the side wall of the clamp, two clamping plates 3 are arranged symmetrically on the top of the base 5, and one end of the clamping plate 3 is provided with a hook 31, which passes through the upper clamp body The top surface of the upper clamp body is clamped on the outer wall of the upper pliers.

A pressing plate 1 is hinged on the top of the rear end of the base. The pressing plate is located on the top of the operating ends of the two clamps, and is used to open the two clamps at the same time. The center of the base is provided with a cutter groove, and the cutter 4 is arranged in the cutter groove. The end of the cutter 4 protrudes from the front end of the base, and the cutter 4 can move up and down along the cutter groove to cut off the umbilical cord between the clamping parts of the two clamps.

The cutting device detachably connects the clamps in the groove of the base 5 through hooks and springs, that is, before the operation, the base 5 and the two clamps are pre-assembled together. Control the two clamps to open at the same time to complete the clamping of the umbilical cord and realize the blocking of blood, and then control the cutter to move down along the cutter groove to cut off the umbilical cord between the two clamps. At this time, drive the clamping plate The hook is separated from the clamp, and the clamp moves from the clamp groove under the force of the spring to complete the separation of the base and the clamp, and the two clamps still hold the umbilical cord incision. The cutting device is pre-assembled before operation, and the cutting work of the umbilical cord can be completed by one person and one hand, which shortens the operation time and simplifies the operation steps.

Referring to Fig. 5 and Fig. 6, in this embodiment, the clamp 2 includes two clamp bodies that are hinged up and down, and a torsion spring is arranged on the hinge shaft, so that the clamping portion 21 of the clamp has sufficient clamping force; The clamp 2 is set in the slot of the base, and since the two clamps are arranged symmetrically on both sides of the base, after the two clamps clamp the umbilical cord, there is still a gap in the umbilical cord between the two clamps 2 Cutting off the umbilical cord will easily cause a small amount of blood to splash, so the clamping portion 21 of the clamp extends out from the end of the base 5, and the clamping portion extends toward the middle of the base, leaving a gap between the clamping portions of the two clamps. Cutting the width of the knife, the clamp of the above structure prolongs the clamping length of the umbilical cord, and the clamping is more stable, which is more convenient for the knife to cut, and also prevents blood from splashing.

Continue to refer to Fig. 3, the card groove on the base is made up of a plurality of positioning plates, comprises upper clamp body positioning plate 23 and lower clamp body positioning plate 24; Lower clamp body positioning plate 24 comprises upper positioning plate and lower positioning plate, and upper positioning plate and the shape of the lower positioning plate are respectively matched with the shape of the top surface and the bottom surface of the lower clamp body, and the lower clamp body remains still during the clamping process of the umbilical cord; the upper clamp body positioning plate 23 is located on the top of the upper clamp body. During the holding process, the upper pliers body rotates around the hinge shaft, and the top of the pliers body is provided with an arc-shaped boss, the arc-shaped boss is concentric with the hinge shaft, and the upper pliers body positioning plate 23 is located at the top of the arc surface.

Referring to Fig. 4, the top of the base 5 is provided with a cardboard groove, and the two cardboards are symmetrically installed in the cardboard groove, the middle part of the cardboard 3 is hinged with the side wall at the end of the cardboard groove, and the buckle of the cardboard extends Out of the card slot, the other ends of the two cards intersect each other, and a spring hole is arranged at the center of the bottom of the card slot, and a card spring 32 is vertically installed in the spring hole, and the card spring 32 abuts against the intersection of the two cards. When installing the clamp 2, press down on the cross end of the two clamps, the spring will compress, the cross end of the two clamps will move down, the other end of the clamp will move up, put the clamp 2 into the slot , the pressure of the clamp is canceled, the spring resets, the hook 31 of the clamp 3 is stuck on the side wall of the clamp, and the fixing of the clamp is completed; after the umbilical cord is cut off, the clamp is pressed down to make the hook 31 of the clamp Separated from the clamp, the clamp 2 is separated from the base under the elastic force of the clamp spring.

The "mountain" shape structure at the cross end of the pallet, the ends of the two pallets are staggered and inserted to realize the simultaneous operation of the two pallets, which further simplifies the operation steps and shortens the operation time.

Referring to Fig. 4 again, this cutting knife 4 is connected with knife column 42, and the inclined chute is set in the base, and knife column 42 is arranged in the chute, and the bottom of chute is provided with cutter spring 41, and the upper end of knife column 42 stretches out base. When cutting the umbilical cord on the top surface of the seat 5, the knife post 42 moves obliquely downward along the chute, so that the cutting knife applies a downward cutting force to the umbilical cord, and at the same time applies a horizontal transverse cutting force, making it easier to cut the umbilical cord. After the cutting is completed, the cutter spring 41 resets the cutter; in order to prevent the cutter from separating from the cutter groove, a bearing pin is set on the base, and the bearing pin passes through the cutter groove horizontally.

Referring to Fig. 2, further, two rotating shafts 7 are arranged symmetrically on the bottom surface of the pressing plate 1, the pressing plate is pressed down to open the two clamps, and the rotating shaft is in rolling contact with the top surface of the upper clamp body, so that opening the two clamps is more labor-saving and improves the operability. sex.
