Abstract: A set for spinal anesthesia has a hollow introducer needle, a spinal needle introducible through the introducer needle into subarachnoid space, and a separate elongated hollow fixing element having a first portion which is fixable with the introducer needle, and a second portion surrounding exclusively the spinal needle and fixable with the spinal needle, so that the spinal needle is movable through the means between a plurality of positions and is fixed by the second portion to the fixing element in each of the positions.

Abstract: A device for IV therapy and the like has a needle and a hollow catheter for inserting the needle and provided with a tip and a rear end having a first inlet with a membrane for introducing the needle and a second separate needle for connecting a syringe or IV tubing, to prevent a blood backflow when the needle is removed. The device also has a needle tip trap in which the needle tip is trapped when the needle is removed from the catheter.

Abstract: A set for continuous epidural anesthesia has an epidural catheter and a device for determining its required length and including an epidural needle insertable into an epidural space and a ruler with shorter and longer scales designed so that when the epidural needle is inserted in the epidural space and the ruler is placed against a skin and parallel to the needle while the epidural catheter is placed parallel to the ruller, the required length of the epidural catheter for anesthesia can be determined on the longer scale.

Abstract: A set for spinal anesthesia has a spinal needle, a stylet, an introducer needle through which the spinal needle is introduced, and a clamp for fixing the spinal needle to the introducer needle to stabilize the spinal needle.

Abstract: A needle cover of an epidural needle for epidural anesthesia with the use of an epidural catheter first insertable into the needle and then into a patient when the needle is removed, has two scales including a shorter scale provided on one side of the needle cover and having a length corresponding to a length of the epidural needle and a longer scale provided on another side of the needle and being longer than said shorter scale by a length corresponding to a required length of the epidural catheter inside the epidural space.

Abstract: A spinal anaesthesia is performed with the use of a step and instruments for removing an antiseptic substance after its application of patient's skin for disinfection and before introduction of a spinal needle, to prevent contamination of central nervous system by the anticeptic substance which otherwise would be introduced with the needle tip.

Abstract: A device and a method for facilitating subcutaneous introduction of a plastic carrier includes an element having a supporting portion arranged to be supported on a skin of a patient, and a guiding portion extending substantially transversely to the supporting portion and having at least one slot formed so that when the supporting portion is placed on the skin of a patient and oriented on a surface projection line of an artery and a catheter is introduced through the slot of the guiding portion the catheter is guided on an edge formed in the guiding portion by the slot so that a tip of the catheter is introduced exactly into the artery.

Abstract: A device and a method for determining a required length of an epidural catheter for a continuous epidural anesthesia, has an element formed as a ruler and having two opposite sides, a shorter scale provided on one side of the ruler and having a length substantially corresponding to a length of an epidural needle, and a longer scale provided on the other side of the ruler and being longer than the shorter scale by a length corresponding to a required length of an epidural catheter inside an epidural space, so that when an epidural needle is inserted in the epidural space and the ruler is placed against the skin parallel to the epidural needle, then when an epidural catheter is placed parallel to the ruler extending from a hub of the epidural needle along the longer scale, its length between the hub of the epidural needle and a beginning of the longer scale corresponds to a required length of the epidural catheter to be inserted into a patient.

Abstract: For translation between a plurality of languages at least two carriers for at least two languages are provided with at least one question and at least one answer at the same locations, and the carriers are aligned with one another so that the questions and the answers are also aligned with one another so as to allow easy identification of the questions and the answer in the respective language.
