Detailed Description

As shown in fig. 1 to 9, the present invention mainly includes a support ring 1, a clip 2, a translation mechanism, and a conduction unit, and the present invention will be described in detail with reference to the drawings.

Support ring 1:

as shown in fig. 1 to 4, the support ring 1 is a circular plastic member, and a groove 11 is formed on the upper surface of the support ring and penetrates through the inner side wall of the support ring. Four groups of through holes 12 uniformly arranged along the circumferential direction are arranged on the side wall of the support ring, and each group comprises two through holes arranged up and down. And a sliding chute 13 positioned on the inner side of the support ring is arranged between the two through holes which are arranged in groups, and the sliding chute penetrates through the inner side wall of the support ring.

The supporting ring is used for supporting and mounting the clamp and the conducting unit.

And (3) the clip 2:

as shown in fig. 6, the clip 2 includes a pair of clamp plates 21 disposed up and down, ear plates 22 fixed on the lower side walls of the clamp plates, and a slide bar 24 disposed between the two clamp plates, wherein the clamp plates include a first portion and a second portion disposed at an obtuse included angle, the first portion is disposed obliquely, the second portion is disposed horizontally, the ear plates on the two clamp plates are hinged together by a hinge shaft 23, a torsion spring is disposed between the two clamp plates, a clamping portion 211 is disposed at a first end of the clamp plate 21, and the width of the clamping portion is greater than the width of the clamp plate. The two clamping parts are contacted and pressed tightly under the action of the torsion spring. As shown in fig. 5, the slide rod is fixedly connected with the hinge shaft and is slidably connected with the slide groove, so that the whole clamp is slidably connected with the support ring along the radial direction of the support ring. The second part of the clamping plate penetrates through the through holes and then extends into one section of the support ring, so that the two clamping plates forming the clamp extend out of the support ring through the two through holes which are arranged in a group. When the second part of the two clamping plates is pinched outside the support ring, the two clamping parts can be kept away, then the umbilical cord edge is placed between the two clamping parts, and the second part of the clamping plates is loosened, so that the umbilical cord edge can be clamped. In order to drive the clamp to move along the radial direction of the support ring, a gear 3 and a worm wheel 31 which are coaxially arranged are rotatably arranged on the inner side of the support ring, a worm 32 is arranged in the support ring through a bearing 34, the worm is meshed with the worm wheel, the gear is meshed with teeth on the side wall of the sliding rod, a knob 33 arranged on the outer side of the support ring is fixed on the worm shaft of the worm, and when the knob is rotated, the rotation of the worm, the worm wheel and the gear can be driven, so that the sliding rod is driven to move along the radial direction of the support ring. Therefore, an installation groove is formed in the support ring, and the gear, the worm wheel and the worm are all arranged in the installation groove. The knob, the worm wheel and the gear form a translation mechanism for driving the sliding rod to move along the radial direction of the support ring.

The clamp is used for clamping the edge of the umbilical cord, and then the clamp is driven to move along the radial direction of the support ring and away from the axis of the support ring through the translation mechanism, so that the edge of the umbilical cord can be pulled, and the contracted umbilical cord is stretched. The drive clamps are operated outside the support ring when opened and moved radially along the support ring, thereby avoiding direct contact with the umbilical cord causing contamination.

A conduction unit:

as shown in fig. 7 to 9, the conducting unit comprises a supporting rod 4, a guide tube 5 slidably disposed on the supporting rod, and a first end of the supporting rod is disposed in the groove and is hinged to the supporting ring. An operating rod 41 is also vertically fixed at the first end of the support rod, a round hole 42 is arranged at the second end of the support rod, and a conduit is arranged in the round hole. As shown in fig. 9, the catheter comprises an outer tube 51, an inner tube 51, and a plurality of guide wires 53 disposed between the inner tube and the outer tube, the inner tube and the outer tube are disposed inside and outside, the inner tube and the outer tube are both plastic tubes, the guide wires are steel wires disposed between the inner tube and the outer tube, and a filler is disposed between the inner tube and the outer tube, and the filler plays a role in fixing the guide wires. The guide wire is arranged, so that the catheter has certain elasticity and hardness, and the catheter can be conveniently extended into an umbilical vein. The guide pipe is arranged in the round hole and is connected with the support rods in a sliding way. When in use, the support rod is swung to enable the second end of the support rod to be placed at the umbilical vein, and then the catheter is inserted into the umbilical vein. One end of the catheter extending into the umbilical vein should be tapered to facilitate insertion and a drug injection port 54 at that end of the umbilical vein to facilitate entry of the drug into the umbilical vein. The guide wire is arranged so that the catheter has a certain hardness, which facilitates the insertion into the collapsed umbilical vein.

The function of the lead-through unit is to open the collapsed umbilical vein and deliver the drug into the umbilical vein.

As shown in figure 1, a handle 6 can be fixed on the outer side wall of the support ring for the convenience of operation, so as to facilitate the holding of the support ring.

The following describes the use of the invention:

(1) placing the umbilical cord on the inner side of the support ring, clamping the edge of the umbilical cord through the clamp, driving the clamp to move towards the outer side of the support ring, further pulling the edge of the umbilical cord, and pulling the umbilical cord open;

(2) and swinging the supporting rod to enable the second end of the supporting rod to be close to the umbilical vein, then extending the catheter into the umbilical vein, and injecting the medicine through the catheter after the catheter reaches a proper position.
