Abstract

The blood-outlet is to one side of the axis of the hollow needle. The end of the needle has a collector or guide which does not cover the blood outlet. The needle occupies a small clearance volume.

Description

Technisches Gebiet der ErfindungTechnical field of the invention

  • - Medizin.- Medicine.
Stand der TechnikState of the art

Bei Frühgeborenen und reifen Säuglingen ist es üblich venöse Blutentnahmen mit handelsüblichen Injektionsnadeln nach manueller Entfernung der Plastikkupplung (Verbindungsmöglichkeit zu einer Spritze) durchzuführen. Das ist notwendig wegen schwieriger Blutabnahmeverhältnisse bei Neonaten (kleine Blutgefäße, geringe Blutmenge). Die bei oben beschriebenem Vorgehen entstehenden Schwierigkeiten bei der Blutentnahme (vgl. unten: "Der Erfindung zugrunde liegende Probleme") treten bei Verwendung der neu beschriebenen "Blutentnahmenadel für Frühgeborene und reife Säuglinge" nicht auf.In premature babies and mature infants, it is common to take venous blood samples commercially available injection needles after manual removal of the plastic coupling (Connection possibility to a syringe). This is necessary because of difficult blood draw ratios in neonates (small blood vessels, small Amount of blood). The difficulties that arise with the procedure described above when taking blood (see below: "Problems underlying the invention") occur when using the newly described "blood collection needle for Premature and mature infants "do not arise.

Der Erfindung zugrunde liegende ProblemeProblems underlying the invention

Bei einer Blutentnahme mit der von mir neu angegebenen Hohlnadel können folgende bisher bestehende Nachteile vermieden werden
The following existing disadvantages can be avoided when taking blood with the hollow needle I have specified

  • - Gefahr der akzidentellen Kontaminierung der Nadel während der Entfernung der Plastikkupplung und die damit verbundene Infektionsgefahr für die Patienten.- Risk of accidental contamination of the needle during removal of the Plastic coupling and the associated risk of infection for the patient.
  • - schlechte manuelle Kontrolle der Nadel: bei dem oben beschriebenen Vorgehen (Blutentnahme mit injektionsnadel nach Entfernung der Plastikkupplung) besteht keine Möglichkeit die Nadel geeignet anzufassen.- poor manual control of the needle: the one described above Procedure (blood is drawn with an injection needle after removal of the Plastic coupling) there is no possibility to handle the needle appropriately.
  • - Akzidentelle Nadeldislokation und Verminderung von Blutverlusten: da bei den bisher verwendeten Nadeln nur im Bereich des Blutauslasses (Ende der Nadel nach abbrechen der Plastikkupplung) die Möglichkeit zum Anfassen besteht, sind die ersten Bluttropfen erst nach loslassen der Nadel sichtbar. Dadurch besteht die Gefahr der Nadeldislokation da die intravenöse Lage leicht zu spät festgestellt wird.- Accidental needle dislocation and reduction of blood loss: there with the Previously used needles only in the area of the blood outlet (end of the needle after breaking the plastic coupling) there is the possibility to touch, the first drops of blood are only visible after releasing the needle. Thereby there is a risk of needle dislocation since the intravenous position is slightly too late is detected.
  • - Gefahr eines vermeidbaren Blutverlustes: da die ersten Bluttropfen erst nach loslassen der Nadel zu sehen sind (vgl. oben). - Danger of avoidable blood loss: since the first drops of blood only after release the needle can be seen (see above).  
  • - das Verbiegen der Nadel, das zu einer Verlegung des Lumens und zur frustranen Venen-/Arterienpunktion führen kann.- the bending of the needle, which leads to a displacement of the lumen and to the frustrating Venipuncture / arterial puncture can result.

Anwendungsgebiet des Gegentandes der ErfindungField of application of the object of the invention

Medizin; Blutentnahmen bei Frühgeborenen, reifen Neugeborenen, oder Patienten mit schlechten Venenverhältnissen.Medicine; Blood sampling from premature babies, mature newborns, or patients with poor vein conditions.

Claims (1)

Innovationen für die in den Patentansprüchen Schutz begehrt wird:
  • - die Form: seitlich zur Achse der Hohlnadel angelegter Blutauslaß,
  • - am Ende der Nadel vorhandene Anfass-, bzw. Führungsmöglichkeit ohne Verdeckung des Blutauslaß und
  • - das sich aus der bezeichneten Anordnung ergebende geringe Totraumvolumen der Nadel.
Innovations for which protection is sought in the patent claims:
  • the shape: blood outlet arranged laterally to the axis of the hollow needle,
  • - At the end of the needle, there is a possibility of touching or guiding without covering the blood outlet and
  • - The small dead space volume of the needle resulting from the designated arrangement.
