Definitions

  • the present invention relates to a device for collecting placental blood.
  • placental blood also called cord blood
  • cord blood which has particularly advantageous properties. This is usually done after the baby has been separated from the umbilical cord.
  • the person responsible for the collection then uses a system comprising one or more collection needle (s) with which he pierces the vein of the cord to collect by gravity the blood which it contains.
  • This operation is relatively long, typically of the order of twenty minutes, which taking into account the blood coagulation process, consequently limits the quantities withdrawn and the quality of the blood withdrawn.
  • the object of the present invention is to provide a device for collecting placental blood which does not have the abovementioned drawbacks.
  • the present invention aims to provide a device for collecting placental blood which is more efficient and which makes it possible to optimize the quantity and the quality of the blood collected.
  • the present invention also aims to provide such a device which is simple, inexpensive and safe to manufacture and use, especially in terms of sterility conditions.
  • the present invention therefore relates to a device for collecting placental blood, comprising at least one sampling needle intended to pierce the vein of the umbilical cord and / or the placenta, as well as a collecting reservoir connected to said at least one needle by intermediate of at least one pipe, the device comprising suction means connected to said at least one needle and suitable for sucking placental blood to supply it to said collecting tank, said suction means comprising a vacuum jar, in particular of the Redon type, simultaneously forming a collecting tank.
  • said suction means further comprise a vacuum pump.
  • the device comprises at least one injection and / or sampling site between said at least one sampling needle and said collecting tank.
  • at least one injection and / or sampling site is provided on the pipe.
  • At least one injection and / or sampling site is provided on the collecting tank.
  • said at least one suction and / or sampling site is used to inject an anti-coagulant product and / or take a blood sample for analysis and / or take the blood contained in said collecting tank.
  • said device comprises means for adjusting the flow of blood and / or means for adjusting suction.
  • said means for adjusting blood flow and / or said means for adjusting suction include an adjustable wheel.
  • said collecting tank contains an anticoagulant product before receiving said placental blood.
  • said device is packaged in a sterile manner and assembled in a common package to be ready for use after opening of said package.
  • This device comprises in known manner at least one sampling needle 10, 11.
  • two needles are provided, which makes it possible to carry out a sampling at two different places and at two successive times.
  • security systems 15 are provided on each needle 10, 11 to avoid any risk of injury before and after the sample is taken.
  • This or these needles 10, 11 is (are) connected (s) to a collecting tank 20 intended to receive the blood drawn.
  • a pipe 40 advantageously connects said collecting tank 20 to said at least one needle 10, 11.
  • the device comprises suction means 30 for sucking placental blood inside the collecting tank 20.
  • suction means 30 for sucking placental blood inside the collecting tank 20.
  • These means Aspiration therefore promotes rapid transfer of the blood to be drawn to the collecting tank 20, which makes it possible to collect a greater quantity of blood, to accelerate the collection process, to improve the quality of the blood collected and to limit the risks of coagulation thereof before it reaches the reservoir coEector 20.
  • the embodiment shown in the figure shows the use of a vacuum jar of the Redon type which is particularly advantageous for the present invention.
  • the Redon jar is a vacuum tank used after surgical procedures to aspirate the last post-operative balances on the patient. The use of such a Redon jar in the present invention makes it possible to obtain a quality and rapid sample.
  • the suction means can also include additional suction means, for example a vacuum pump or a peristaltic pump or any other type of pump. Of course other means of suction would also be possible.
  • a sampling tank connected or disposed inside a vacuum tank could also be used and other systems could also be used.
  • the sampling device comprises at least one injection and / or sampling site 51, 52, 53 provided between said at least one needle 10, 11 and said collecting tank 20.
  • an injection site 51 for injecting an appropriate anti-coagulant product for example heparin or CPD
  • a second sampling site 53 to take all of the blood contained in the collecting tank 20 at the end of the sampling process.
  • injection and / or withdrawal sites 51, 52, 53 can be arranged on the pipe 40, as shown, but they could also advantageously be produced directly on the collecting tank 20.
  • an insulated bag containing an anticoagulant can be connected to the device, for example at said injection site.
  • This pocket can for example be isolated by an adjustable or breakable device, allowing or not the passage of its contents to the collecting tank, as necessary.
  • an agitator device 25 is provided in the reservoir 20, for example a magnetic or movement agitator. This makes it possible in particular to improve the mixture of the blood drawn with the anticoagulant. To ensure proper operation of the device, the suction must not be too high, which would risk causing a constriction or blockage of the pipe 40, or too weak to be effective.
  • the device therefore advantageously comprises suction adjustment means 70, which can be produced in the form of an element adapted to modify the section of the pipe 40.
  • an adjustable wheel could be used.
  • adjustment means provided directly on the suction means 30, or even on the collecting tank 20 would also be possible.
  • means for regulating the flow of blood 60 which are advantageously disposed directly downstream of the sampling needles 10, 11, and which can also be produced in any desired manner, for example by means of '' an adjustable wheel.
  • Filters can be provided at the various sampling and / or injection sites, as well as upstream of the reservoir 20. For example, the presence of such a filter can allow the reservoir to be placed at atmospheric pressure immediately upon sampling. completed without risk of contamination and under sterile conditions.
  • a particular advantage of the present invention relates to its safety in use, and in particular its sterile nature.
  • the device of the invention can be assembled, sterilized and then packaged in a sterile manner in a common package, so that the user, when he wishes to draw placental blood, has only to open the sterile packaging and pierce the umbilical cord to draw blood without having to make any other assemblies.
  • the sterility of the device is therefore guaranteed at all times.
  • the present invention therefore makes it possible to provide a placental blood collection device which simplifies the collection process, which makes it safer and more efficient by optimizing both the quantity of blood collected and the quality thereof.
