    DETAILED DESCRIPTION

    [0029] As used in this document, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. As used in this document, the term “comprising” (or “comprises”) means “including (or includes), but not limited to.” When used in this document, the term “exemplary” is intended to mean “by way of example” and is not intended to indicate that a particular exemplary item is preferred or required.

    [0030] In this document, when terms such as “first” and “second” are used to modify a noun, such use is simply intended to distinguish one item from another, and is not intended to require a sequential order unless specifically stated. The term “approximately,” when used in connection with a numeric value, is intended to include values that are close to, but not exactly, the number. For example, in some embodiments, the term “approximately” may include values that are within +/−10 percent of the value.

    [0031] FIG. 1 shows a perspective top view of a protective device 11 for the hand 12 of a medical personnel when puncturing an umbilical cord 13 of neonates. The protective device 11 comprises an umbilical cord channel 14 for receiving the umbilical cord of the neonate and two wings 15 arranged at the upper edge of the umbilical cord channel 14 as hand protection. The wings 15 extend laterally away from the umbilical cord channel 14 in the use position of the protective device 11.

    [0032] The protective device 11 further comprises two handle strips 16 arranged on the two wings 15. One handle strip 16 extends from each of the lateral wings 15 in the depth direction of the umbilical cord channel 14. The height of the two handle strips 16 corresponds at least to the depth of the umbilical cord channel 14. The umbilical cord channel 14 is thus arranged between the two handle strips 16.

    [0033] The protective device 11 may have, for example, a length between 10 cm and 20 cm, such as approximately 15 cm. The umbilical cord channel 14 of the protective device 11 is, for example, curved, U-shaped or polygonal and may have an upper width of 15 mm to 25 mm, such as approximately 20 mm. According to the embodiment example shown in FIG. 1, the umbilical cord channel 14 has a constriction 10 at the distal end 19 and at the proximal end 18, respectively, for fixing the umbilical cord 13. For example, this constriction 10 is V-shaped. The constriction 10 provides better fixation of the umbilical cord 13 in the umbilical cord channel 14, but the constriction 10 is designed in such a way that the umbilical cord 13 and in particular the blood flow through the umbilical cord 3 is not pinched off.

    [0034] As can be seen from FIG. 1, the two wings 15 extend along the entire length of the umbilical cord channel 14. The two wings 51 have a greater lateral extent at the distal end 19 of the protective device 11 than at the proximal end 18. In particular, the lateral wings 15 become continuously narrower toward the proximal end 18. For example, the two wings 15 have a width of 2.5 cm to 5.0 cm at the distal end 19 and a width of 1.0 cm to 2.5 cm at the proximal end. According to a variant, the inner side of the umbilical cord channel 14 may be designed to be softer than a puncture needle 11, so that the puncture needle 11 can be fixed in the inner side of the umbilical cord channel 14 when piercing through the umbilical cord 3 and at the same time the leakage of umbilical cord blood can be reduced. In particular, the inner side of the umbilical cord channel 14 may be designed to be flexible for this purpose. This has the advantage that after puncture and sampling, the puncture needle 11 can be pierced through the umbilical cord 13 and fixed in the inner side of the umbilical cord channel 14. The puncture needle 11 can remain there until the umbilical cord 13 has been separated and set aside. Puncture injuries after sampling are thus also reliably prevented. For example, the inside of the umbilical cord channel 14 has an extra coating or the umbilical cord channel 14 is made of a softer material, in particular plastic, but has sufficient wall thickness to prevent puncturing with the puncture needle 11.

    [0035] FIG. 2 shows a perspective view from below of the protective device 11 from FIG. 1. As can be seen in particular from FIG. 2, the two handle strips 16 extend almost over the entire length of the umbilical cord channel 14 or of the protective device 1. The two handle strips 6 each have an indentation 17, each for a finger of the hand 12 of the medical personnel, in particular the thumb and index finger of the hand 12. The indentations 17 are arranged approximately in the proximal third of the protective device 11.

    [0036] FIG. 3 shows a side view of the protective device 11 from FIGS. 1 and 2. It can be seen particularly well from FIG. 3 that the umbilical cord channel 14 is angled towards the proximal end 18 in the depth direction of the umbilical cord channel 14, i.e. downwards in the position of use of the protective device 11. According to the invention, the angle of the proximal end 18 to the distal end 19 of the umbilical cord channel 14 is between 30 degrees and 60 degrees, or between 40 degrees and 50 degrees.

    [0037] It can also be seen from FIG. 3 that the indentations 17 on the handle strips 16 are arranged approximately in the area of the bend and that the protective device 11 can be laid down in a stable manner on the two handle strips 16. Since the two handle strips 16 are arranged on opposite sides of the umbilical cord channel 14, the umbilical cord 13 can also be punctured in the laid-down state, in particular without the protective device 11 tipping away laterally.

    [0038] FIG. 4 shows a protective device 11 for the hand 12 of a medical personnel during the puncture of an umbilical cord 13 of a neonate. The medical personnel can hold the protective device 11 in one hand 12 by means of the handle strips 16 arranged below the two wings 15 in the position of use. The umbilical cord 13 of the neonate is placed in the umbilical cord channel 14 and can be punctured with the other hand of the medical personnel by means of a puncture needle 21. The umbilical cord channel 14 protects the hand 12 of the medical personnel from puncture injuries caused by piercing the umbilical cord 13, and the lateral wings 15 protect the hand 12 of the medical personnel from puncture injuries caused by slipping or the like from the umbilical cord channel 14, for example, due to unforeseen movements of the mother and/or the neonate. Since the hand 12 for holding the protective device 11 is positioned completely below the wings 15, the umbilical cord 13 placed in the umbilical cord channel 14 can be punctured anywhere along the complete length of the umbilical cord channel 14 without the risk of puncture injuries.

    [0039] The protective device can be held in one hand by the medical personnel by means of the two handle strips. The umbilical cord channel, which is arranged between the two handle strips, extends through the palm of the medical personnel's hand, which corresponds to a particularly ergonomic position for puncturing the umbilical cord. The umbilical cord channel prevents puncture injuries caused by unintentional piercing of the umbilical cord. The wings arranged on the upper edge of the umbilical cord channel, protect the hand of the medical personnel from puncture injuries caused by slipping of the needle or other unwanted movements, for example caused by movements of the mother or the neonate. The holding hand of the medical personnel is thus located below the umbilical cord channel and is protected from above by the lateral wings. Due to this arrangement, the umbilical cord can be punctured at any point of the umbilical cord channel, especially at a point where a corresponding vessel of the umbilical cord is clearly visible for blood sampling. In contrast, for example, in the prior art according to EP 2 913 004 A1, the umbilical cord can only be punctured in the puncture area of the umbilical cord channel, which is further located in close proximity to the fixing section where the medical personnel fix the umbilical cord on the upper side of the umbilical cord channel with a finger.

    [0040] The features and functions described above, as well as alternatives, may be combined into many other different systems or applications. Various alternatives, modifications, variations or improvements may be made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
