One end of the upper clamp body and one end of the lower clamp body are linked ends with positioning arc flanges, the other end of the upper clamp body and the other end of the lower clamp body are open ends, an upper arc hook and a catching groove of the upper clamp body and the lower clamp body are connected to form a whole, the upper clamp body is a single-side cavity with one open side, the height of a box bottom surface of the single-side cavity is more than that of a lateral surface of the single-side cavity, the lower edge of the box bottom surface is provided with a step, and the box bottom surface and a wavy surface of the lateral surface of the single-side cavity are matched with the lower clamp body. A smooth surface of the box bottom surface faces to a new born child and does not touch the new born child, simultaneously, the phenomenon of loosening an umbilical cord does not happen, the usage is safe and reliable, the umbilical cords with different thicknesses can be automatically adjusted by using the height difference between two side edges of the single-side cavity and the box bottom surface without the midwife operation, and the single-side umbilical clamp saves time and labor. The single-side umbilical clamp is separated from the catching groove by using a special tool to toggle the arc hook to be detached, the usage is convenient, the detachment is quick, and the single-side umbilical clamp can be widely popularized and applied in clinic and can be used singly or with an umbilical cutter.

Description

Single-side umbilical clamp

Technical field

The present invention relates to a kind of medical anchor clamps, be used for the single-side umbilical clamp that umbilical cord is handled when particularly neonate is delivered a child.

Background technology

The umbilical cord that needs the mother and baby will be linked together after pregnant woman childbirth, the neonate birth is cut off, at this moment need earlier with " umbilical clamp " clamping umbilical cord, cut off with the blood blocking-up and then with the umbilical cord of neonate and placenta materna junction, stay neonate a part of umbilical cord on one's body, wait umbilical cord downright bad disengaging naturally because of depletion of blood flows.

Because of the difference of neonatal size and umbilical cord thickness very big, also distinctive sticking because of umbilical cord itself, sliding, moisture performance, so the clamping effect of existing umbilical clamp is also unstable, versatility is not strong, though through the patent No. 200620107590.9,200720106459.5,200710071198.2 the patent of " umbilical clamp " is constantly put into practice improvement, improve and simplify, make its clamping stable performance and compensating roller function is arranged, but its compensating roller midwives that also need lean on goes to regulate with manual method when using because of umbilical clamp, so trouble is regulated in the operation of the umbilical clamp of said structure, use inconvenience, versatility is not enough, also is not suitable for extensively promoting the use of clinically.

Summary of the invention

Technical problem to be solved by this invention is: a kind of single-side umbilical clamp is provided, clamps effective, stable performance, exfoliation time cord dropping is short, has significantly reduced nursing time and expense, and simple, convenient, rapid, suitablely especially apply clinically.

The present invention addresses the above problem the technical scheme that is adopted: single-side umbilical clamp, by double wedge is arranged on the outer surface, groove, on the inner surface serrate on, lower clamp is formed, and on, one end of lower clamp is for having locating flange, the disjunctor end of curved flanges, the other end is an opening, use, arc hook and catching groove on the lower clamp connect into integral body, described upper clamp is the single face chamber of an opening, the box bottom surface height in described single face chamber is greater than the lateral height in single face chamber, use facing to neonate described box bottom surface, on the lower limb of described box bottom surface step is arranged, lower end, side, single face chamber is the setback face, and lower end, box bottom surface, the setback face cooperates with lower clamp.

Compared with prior art, the invention has the advantages that: the two ends of this umbilical clamp constitute two tight locking buttons with umbilical clamp snap close jail, and in the middle of the upper clamp of umbilical clamp is the single face chamber, box bottom surface shiny surface with the single face chamber during use can not bump the pain neonate facing to neonate, the umbilical clamp phenomenon that gets loose can not take place simultaneously, safe in utilization, reliable, and cramping is carried out to umbilical cord in the gap that makes full use of between single face chamber lower limb and lower clamp, utilize single face chamber dual-side and box bottom surface that high and low difference is arranged in addition, can the umbilical cord of different thicknesses be automatically adjusted.Promptly the clamping face with single face chamber and dual-side carries out clamping to umbilical cord, umbilical cord can not misplaced, wrong to piece together mobile clamping stable, and umbilical cord is thick more to hold tightly more, and chucking power doubled than originally.Do not need midwives operation just can regulate automatically, save time, laborsaving.Make it break away from the just detachable umbilical clamp down of catching groove as long as stir the arc hook with specific purpose tool, easy to use, dismounting rapidly, therefore wide popularization and application clinically, this umbilical clamp can use separately also can with the supporting use of umbilical cord cutter.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.

Umbilical clamp is by an end disjunctor, and 1,2 pairs of integral body that are connected into of the upper and lower clamp of other end opening are formed.

The groove of connection, double wedge 3 are arranged, as shown in Figure 1 on the outer surface of upper and

lower clamp

1,2.

On the opening termination of lower clamp 2 chute 9 is arranged, the chute below cooperates also and the catching groove 10 that through hole communicates on the termination with arc hook 5 in addition, also has curved flanges 4 in the middle of the two ends inwall, that the inwall intermediate surface has is uniform, apart from one another by the triangle straight-tooth 8 of circular arc transition and at the contrate 7 on circular arc transition face and straight-tooth 8 limits, as Fig. 2, shown in Figure 3.

There is arc hook 5 the opening end of upper clamp 1, mid portion is the single face chamber of an opening, box bottom surface 11 outer surfaces have pattern, can be made into needed zodiac logo as required, the side surface in single face chamber has the setback face 13 of big rise and fall in the opening part lower end, the height of box bottom surface 11 is greater than the height of side surface, the lower limb of box bottom surface extends the circular arc plane, circular arc horizontal edge place also forms two different steps 12 of thickness, the nearly edge of opening in side surface upper end, single face chamber has locating flange 6 and curved flanges 4 staggered positions to distribute, not at grade, do not make, lower clamp 1, before does not understand 2 location, after rock, as Fig. 1, Fig. 2, shown in Figure 3.

During use, opening arc hook 5 is placed on neonatal umbilical cord between the upper and

lower clamp

1,2, and with box bottom surface 11 against neonate umbilicus place, (original umbilical clamp uses just opposite, be that chamber face with the single face chamber is against neonate,) will hold then tightly, with arc hook 5 along chute 9 fastenings in entering catching groove 10 of sliding, the locating flange 6 at the opening of at this moment upper and

lower clamp

1,2, disjunctor end place cooperates the location with curved flanges 4, two ends at umbilical clamp have constituted tight locking button, and umbilical cord locking is not buckled and can move left, right, front and rear.

Because of neonate big, little difference is very big, umbilical cord also has thickness and difference in size very big, when last, when lower clamp clamps, between setback face bigger gap is arranged because of the single face chamber box bottom edge of upper clamp and lower end, side, box bottom surface 11 lower limbs at first touch umbilical cord during use, straight-tooth 8 on the lower clamp, contrate 7 embeds umbilical cords rapidly makes the umbilical cord location not allow its slip, the sawtooth on the setback face 13 also touches umbilical cord under the upper clamp then, at this moment the inwall of sawtooth and lower clamp 2 also clamping simultaneously compress umbilical cord, promptly by having constituted twice clamping seal face between single face chamber on the upper clamp and lower clamp inwall, umbilical cord is thick more hold tight more, thereby the umbilical clamp that makes chucking power increase by a multiple proportions prior art holds tighter.

The edge that close in addition neonate is the box bottom surface on one side contacts with umbilical cord, it is less to imbed the contact surface of pushing down umbilical cord because of the edge is thin, therefore the umbilical cord of the inside is dry easily, dried as can to become flexible earlier soon, outside the chamber in existing single face chamber faces, clamping gap that setback face 13 and lower clamp are 2 and the width all area than the clamping of box bottom edge are big doubly a lot, therefore the umbilical cord drying of outside can not become flexible slowly yet, thus umbilical clamp just can not come off, safe in utilization.(originally situation is just opposite, and the umbilical clamp that has become flexible the outside will be slided outward umbilical clamp is come off, and therefore has unsafe hidden danger.)

Umbilical clamp clamps the back and shears with disinfection tool, the place of cutting off also need remake and disinfect, umbilical clamp is stayed the umbilical cord band edge, because of barrier effect has well shortened the nursing time greatly, just can make that the umbilicus head is dried-up to come off naturally general 24～36 hours umbilical clamp clamping time, existing this umbilical clamp only need just can make that the umbilicus head is dried-up to come off naturally in 18～24 hours.If umbilical clamp can not come off automatically, need only with making arc hook 5 break away from catching grooves 10 in the specific purpose tool insertion catching groove 10 and just can unload umbilical clamp, use, easy to operate, quick convenient, rapidly.

Umbilical clamp also can be connected on the umbilical cord cutter 14 by the groove on its outer surface, double wedge 3 except that above-mentioned independent use, with the 14 supporting uses of umbilical cord cutter, as shown in Figure 5.
