Definitions

  • the invention relates to a device for aspirating body fluids in surgical procedures with a pump and a pump connected to the suction head, the suction-side, free end having a plurality of suction ports.
  • Such a device has become known, for example, as a so-called “Yankauer” and usually consists of a hose or tubular suction attachment, which can optionally be connected to a conventional suction pump with the interposition of a connecting hose
  • the free, suction-side end of the suction attachment usually has a central suction opening, the diameter of which is between 2 and 10 mm, depending on the application Circular cross-section and may be formed with a tapered or a flattened tip, but also embodiments have already become known in which the free end of the suction attachment or of the suction head carries a plurality of suction openings
  • a suction tube with a plurality of distributed over the length of the tube arranged suction openings has become known.
  • Cesarean section is an operative method of termination of pregnancy or childbirth, having previously been associated with an increased risk of Mother and / or child before or at the birth carried out.
  • the caesarean section becomes more frequently also without compelling medical Reasons, because today's trend towards a planned and calculated date of birth with a short, fast and low-risk birth goes.
  • the cesarean section is performed more frequently today than it used to be. While the incidence of caesarean sections at large hospitals was 15 to 20% 15 years ago, today it is often 30%. One distinguishes between the primary cesarean section and the secondary cesarean section.
  • the primary caesarean section is decided on the operation before the natural birth has begun. This may be the case, among other things, in situations in which the cake dissolves prematurely, the cake is completely or partially in front of the inner cervix and this misplaced or suspected mismatch between the pelvic measurements of the mother and the head diameter of the child.
  • a secondary caesarean section the need for a caesarean section arises only during birth. It is usually an emergency situation, whereby the caesarean section must be carried out within 20 to 30 minutes.
  • Reasons for such a secondary caesarean section may be a threatening child emergency situation, an obstetric birth or lack of birth progress, an umbilical cord prolapse or a heavy bleeding during childbirth.
  • the constantly leaking blood is discontinuously aspirated with the aid of a so-called "Yankauer” instrument, the aspiration being performed until the amniotic fluid is reached During suction, the Yankauer aspirator is moved from one end of the injection to the other
  • the Yankauer aspirator is moved from one end of the injection to the other
  • blood immediately returns to the area of the incision as soon as the suction instrument is moved away from the relevant point and moved further along the incision
  • the wound is usually completely filled with blood again so that as a whole such a suction device is unable to aspirate the blood in such a way that the doctor has a clear view of the wound Optically do not check the progress of the cutting process in such a way that the possi with a child's injury from the cutting instrument.
  • the present invention therefore aims to provide a suction device, with which it is possible to make a more efficient suction and to ensure that the wound is always free of blood so that a visual control of the cutting process can be made by the attending physician.
  • the device of the type mentioned is characterized essentially by the fact that the suction openings are arranged distributed over the free end of the suction head over a length which exceeds the width of the free end.
  • the suction openings are thus arranged distributed over the elongated free end of the suction head and it is thereby created the opportunity in the longitudinal direction to detect a larger portion of the incision and in particular when the free end of the suction head is formed with a length, which substantially corresponds to the length of the incision, to grasp the entire area of the incision in one go and simultaneously absorb the blood emerging along the entire length of the incision.
  • the suction head is thus formed substantially elongated, wherein the suction openings extend over the length of the free end, wherein a shape is advantageous in which the length of the suction head substantially exceeds the width of the free end of the suction head.
  • the free end of the suction head has a length which corresponds to at least four times, preferably at least eight times, the width of the free end. This effectively prevents blood from flowing from the wound into the abdomen and completely flooding the area of the incision so that the doctor can no longer have visual control of the progress of the cutting process.
  • the suction head is designed such that the suction openings cover the entire area of the incision, so that the blood is sucked off directly at the outlet points before it is sucked up Quantities can reach the area of the wound.
  • the end of the suction head which houses the suction openings is bevelled. Such a beveled end of the suction head serves to better position the suction holes directly on the cutting surface and also allows unhindered access to the incision for the surgeon, so that the blood can be better sucked.
  • the suction openings are arranged here at the free end only on one longitudinal side and possibly the front side of the suction head, wherein for example the suction openings can be arranged on that longitudinal side, which, as previously mentioned, is chamfered.
  • the suction takes place on the bevelled longitudinal side, namely the front side, of the suction head, wherein the other longitudinal side, namely the back, for example, is used to hold the wound in a gaping position.
  • the suction device can thus also be used simultaneously as a holding instrument to ensure the doctor a clear view of the wound.
  • the training can be developed such that an area facing away from the free end of the suction head is formed kinked or bent. This results in particular better visibility for the treating physician, if, as it corresponds to a preferred embodiment, the free end of the remote end portion of the suction head in the direction away from the provided with the suction openings side of the suction head is bent or bent.
  • suction channels In order to ensure a uniform suction along the entire length of the suction head, extending in the interior of the suction head between the suction openings in the suction direction webs to form suction channels. Through such suction channels a directed suction flow is favored within the suction head, wherein a corresponding suction power is ensured even for the external suction openings.
  • Nisse in the interior of the suction head is further provided with advantage that in each case a projecting strip is arranged in the interior of the suction head on opposite inner walls. With such a design, a uniform suction over the entire length of the suction head is ensured.
  • a further improvement results according to a preferred development, if between the opposing strips a passage cross section for the extracted liquid remains, which corresponds approximately to the sum of the cross sections of the suction openings, in particular pressure losses are avoided and uniform flow conditions are favored.
  • the suction head can be connected via a pipe with the suction pump, wherein the variability is increased when the tube is detachably connectable to a connection opening of the suction head.
  • the suction head can be removed in a simple manner and exchanged for corresponding suction heads of other dimensions or it can be connected to a conventional "Yankauer" aspirator.
  • FIG. 2 shows a cross section through the suction head according to FIG. 1
  • FIG. 3 shows a longitudinal section through the suction head according to FIG.
  • a suction head 2 is connected to a connected to a suction pump suction pipe 1, not shown.
  • the free end 3 of the suction head 2 is formed chamfered and has a plurality of suction openings 4.
  • a cut edge guard 8 may be provided, which serves to guide a cutting instrument, in particular a scalpel, along this edge.
  • the straight region 7 of the suction head 2 merges into an angled section 9, whereby a particularly functional shaping is achieved by this bending, which allows the attending physician in a simple manner in the region of the incision.
  • connection between the tube 1 and the suction head 2 is effected in a simple manner in that the tube 1 is inserted into a connecting piece 13 of the suction head 2, which carries a stop element for limiting the insertion depth.
  • the suction openings 4 extend over a length 1 of the free end 3 of the suction head 2, which exceeds the width b.
  • a suction instrument having an elongated free end which is particularly adapted to the shape of a surgical incision, whereby as far as possible the suction openings 4 extend over such a length, and preferably over the entire length of the suction head wide area and can be kept free from escaping blood.
  • an accumulation of larger amounts of blood in the area of the wound is prevented, whereby at the same time the risk of infection is substantially reduced.
