摘要:
The present invention provides a highly automated puncture system for inserting a cannula or a needle into a blood vessel of a person or an animal. The puncture system has an acquisition module that allows for determining at least a location of a blood vessel underneath of the surface of a skin and is further enabled to determine an optimal puncture location that is well suitable for inserting a cannula into the blood vessel. Further, the puncture system has an actuator for moving and aligning the cannula to a determined position. The system is further adapted to autonomously insert the cannula into the blood vessel for multiple purposes, such as blood withdrawal, venous medication and infusions.

The invention relates to a highly automated puncture system for inserting a cannula or a needle into a blood vessel of a person or an animal. The puncture system has an acquisition module that allows for determining at least a location of a blood vessel underneath of the surface of a skin and is further enabled to determine an optimal puncture location that is potentially suitable for inserting a cannula into the blood vessel. Further, the puncture system has tissue analysis means to analyse the skin surface in the proximity of the puncture location to check whether the skin is suitable for punctuation. This prevents puncturing the skin at locations where scars, wound and the like can be found.

The present application relates to a puncture system for inserting a cannula or a needle into a blood vessel of a person or an animal. The puncture system (100) has location determination means (108) for determining at least one location of the blood vessel. The location determination means are mechanically flexible such that their shape is adaptable to the shape of a body part of the person or animal. Furthermore, the system comprises processing means (112) for determining a puncture location (124) of the blood vessel depending on the output of the location determination means.

The invention relates to a system for guiding a probe over the surface of the skin of a patient. Performing measurements with ultrasound techniques for small structures such as blood vessels need well-defined spatial relationship between the measuring probe and the tissue which has to be examined. The invention seeks to ensure a movement of the measuring probe in a controlled and precise way over the skin. Therefore, a system 1 is suggested which comprises a probe holder 2 to which a probe 4 is rigidly attachable. The probe holder 2 is moveable along at least one rail 5, 5′. The rail can be wrapped around the patient 3 or a body part 7 of the patient or the animal.

The invention relates to a phantom for simulating the ultrasound guided insertion of a needle in a blood vessel of a human body site. The phantom comprises: a skin mimicking layer (2), formed in a first material; —a tissue mimicking layer (3), formed in a second material and at least one artificial blood vessel (4a, 4b, 4c), formed in a third material, the first, second and third material being arranged to reproduce both the mechanical and the ultrasound properties of the corresponding parts of the human body site. Thanks to the invention, the phantom permits a realistic simulation of a human body site behavior.
