Definitions

  • the invention relates to a catheter puncture set.
  • a catheter is usually placed according to the "Seldinger" method.
  • the vessel into which the catheter is to be inserted is first punctured with a hollow puncture needle.
  • a guide wire is then inserted into the vessel through the hollow puncture needle, after which the hollow needle is over
  • the guidewire is then withdrawn again, then the guidewire is advanced and the vessel is expanded using a dilator that is pushed over the guidewire.
  • the actual catheter is threaded over the guidewire and inserted into the vessel and moved into the desired end position The guidewire is then withdrawn through the catheter
  • this method allows the catheter to be inserted, but is extremely cumbersome. A large number of different handles and instruments are required to insert the catheter. Furthermore, due to the multiple insertion and removal of various objects, there is a risk that other objects or people will be contaminated with blood. Finally, there is a risk of air embolism if there is a slight negative pressure in the punctured vessel.
  • the invention is therefore based on the problem of specifying a puncture set that makes it easier to place a catheter.
  • the invention provides a catheter puncture set, comprising:
  • a tubular housing with an elongated housing section which merges into an extension section and from which a branch section branches off at an angle, the housing section and the branch section having a continuous lateral opening, a flexible sheath, which extends along the branch section and the housing section and closes the side opening, into which a catheter can be inserted, and a puncture needle which emerges from the housing with its tip and extends along the elongated housing section and the extension section, the housing can be drawn in behind the branching point of the branching section and then the catheter can be pushed out of the housing via the branching section and the housing section.
  • the puncture set according to the invention represents a quasi-closed system that does not require a guide wire and other additional dilatation devices and the like. Rather, in the cutlery according to the invention, only the vessel is punctured with the puncture needle protruding from the housing, the housing being pushed into the vessel as well. To ensure this in a particularly simple manner, the housing tip, the jacket tip and the needle tip can form an essentially conical shape with one another in the puncture position, which enables simple insertion. After the puncture, blood enters the puncture needle, which according to the invention can open into a blood collection container which can be moved together with it.
  • This blood collection container which is expediently made of a transparent plastic, allows the successful puncturing to be recognized immediately when blood is accumulating therein.
  • the puncture needle is withdrawn, the housing section and the jacket located therein remain in the punctured vessel and seal it from the outside.
  • the puncture needle is pulled past the branch point of the branch section, so that access from the branch section to the housing section is released.
  • only the catheter has to be pushed into the housing section via the branch section and then directly from the housing into the punctured vessel and pushed as far as desired.
  • To remove the housing it is then pulled out of the patient, after which the jacket is pulled out of the laterally open housing and detached from the catheter. The catheter is then exposed.
  • a catheter can be placed much more easily and with far fewer hand movements than is the case with the prior art according to "Seidinger".
  • a further advantage is that it is a quasi closed system in that it is a leak blood is largely avoided.
  • the puncture needle itself can be accommodated in a needle tube which only releases the needle tip and which can be moved together with the needle with respect to the housing. It is particularly advantageous if the puncture needle can only be pulled out of the housing up to a first stop. By means of this stop, it is advantageously avoided that the pointed puncture needle contaminated with blood is pulled completely out of the housing and represents a source of danger which could injure the hospital staff or the doctor. Rather, the puncture needle can only be moved up to the stop in the housing. If the puncture needle is also received in the needle tube, it is completely encapsulated, which is even more advantageous for safety reasons. This configuration also fulfills in some countries, such. B. existing safety regulations in the USA, according to which puncture needles and the like must be stored immediately after use to avoid injury.
  • a blocking element is provided to prevent the drawn puncture needle from being inserted again. This prevents the puncture needle from being pushed into the vessel again due to careless movement or by mistake, which can then be injured if necessary. It is also not possible to push the needle out after the catheter has been inserted and the housing has been removed.
  • the first and / or the second stop can be formed by means of a projection which is formed on the needle tube and which abuts a corresponding counter bearing on the housing.
  • the puncture needle advantageously opens into a blood collection container. If the needle is now withdrawn, it is at least partially filled with residual blood, which can sometimes drip from the needle after being withdrawn.
  • means on the container side are provided for sucking up residual blood located in the puncture needle.
  • These means can be designed in a simple manner in the form of a flexible and curved lid closing the blood collecting container, which can be moved between a position in the blood collecting container and an outwardly curved position. For puncturing, the lid is curved inwards, after pulling the needle the flexible lid is pulled outwards, so that a negative pressure is created in the container, which sucks the residual blood from the puncture needle into the container.
  • connection means for a syringe or the like are provided in the interior of the blood collection container, which make it possible, if necessary, for. B. in an emergency immediately after the puncture of the vessel via the puncture needle a drug or the like.
  • locking means are provided for locking the puncture needle in its puncture position against being drawn into the housing.
  • These locking means which according to an embodiment of the invention comprise a threaded attachment provided on the extension section, with which a counter bearing provided on the blood collection container cooperates, prevent the puncture needle from being accidentally pushed into the housing during the puncture and the puncture can no longer be continued.
  • a sealing element that seals the blood collection container can be provided on the extension section.
  • the flexible jacket can cross-section z. B. be semicircular, so that it can be used safely and firmly in the housing section and the branch section and on the other hand securely seals to the outside. If the sheath is pulled out of the housing after the catheter has been inserted, the catheter is automatically exposed.
  • the jacket can also be tubular and slotted. In this case, the sheath is quasi closed, but when pulled out, it can be removed from the catheter due to the longitudinal slot that the Coat goes through, be peeled off. Depending on how far the sheath is closed, it is expedient to provide an opening on the sheath in the region arranged in the branch area through which the puncture needle, which may be guided in the needle tube, enters the sheath.
  • a clamping section is provided on the jacket region arranged in the branch section and is clamp-retained in a clamping section formed on the branch section. With this clamping section it is possible to fix the casing in its position with respect to the housing.
  • a hold-down device for releasably holding the clamp of an inserted catheter is provided on the jacket end located in the branch section.
  • This hold-down device enables the catheter inserted into the branch section to be clamped in position. This makes it possible to completely prefabricate the catheter puncture set, that is to say to insert the catheter already in the branch section and to hold it there with the clamping section.
  • the doctor placing the catheter therefore does not have to first thread the catheter into the branch section, but only has to loosen the clamping section and can then insert the catheter into the vessel immediately after withdrawing the puncture needle.
  • the clamping section and / or the hold-down device can expediently be formed by means of one or more radially projecting ribs which, like the jacket, likewise consist of flexible material, in particular a soft plastic.
  • the hold-down device itself can be connected via a tab so that it cannot be lost.

This depression also has a locking effect because - regardless of the locking option provided on the container anyway - the puncture needle cannot be withdrawn as long as the housing engages in the depression. Pulling back is only possible after slight twisting and loosening of the procedure.
  • the tip of the jacket itself is expediently designed to be flexible and flap-like with a tapering shape in order to achieve the conical shape.
