Abstract

A blood pressure cuff (10), for determining the blood pressure in newborns, includes a chamber section (20) with an air chamber (22) and a handling section (30) for placing and fastening the chamber section (20) around an arm (100) of a newborn. The air chamber (22) has a chamber wall (24), which has, along a circumferential direction (U) of the air chamber (22), a longitudinal sealing seam (40). Two longitudinal edges (26a, 26b) of the chamber wall (24) are connected to one another overlappingly opposite each other in an airtight manner by the longitudinal sealing seam (40).

First claim

What is claimed is:

1. A blood pressure cuff for determining blood pressure in newborns, the blood pressure cuff comprising:
a chamber section with an air chamber having a chamber wall;
a handling section for placing and fastening the chamber section around an arm of a patient;
a longitudinal sealing seam of the chamber wall, the longitudinal sealing seam having a longitudinal sealing seam extent along a circumferential direction of the air chamber, the longitudinal sealing seam connecting two longitudinal edges of the chamber wall to one another, the two longitudinal edges overlapping each other and extending from an opposite direction with respect to each other, with the two longitudinal edges in an overlapped state, to form an airtight seal at the longitudinal sealing seam, each of the longitudinal edges having a course comprising at least a first extent, a second extent extending from the first extent at an angle relative to the first extent and a third extent extending from the second extent at an angle relative to the second extent and with two first end transverse edges overlapping each other and two second end transverse edges overlapping each other.

2. A blood pressure cuff in accordance with claim 1 , wherein a width of the longitudinal sealing seam corresponds to an overlapping width of the two longitudinal edges of the chamber wall.

3. A blood pressure cuff in accordance with claim 1 , wherein the longitudinal sealing seam is located in at least some sections on an outer side of the chamber section relative to a placement orientation of the blood pressure cuff.

4. A blood pressure cuff in accordance with claim 1 , wherein a surface of the chamber section or of the handling section or of both the chamber section and the handling section has a rougher surface structure than other surfaces of the blood pressure cuff.

5. A blood pressure cuff in accordance with claim 1 , wherein the handling section or the chamber section or both the handling section and the chamber section have a fastening surface on at least one side for fastening the handling section on the chamber section.

6. A blood pressure cuff in accordance with claim 5 , wherein the fastening surface covers the longitudinal sealing seam at least partially.

7. A blood pressure cuff in accordance with claim 6 , wherein the fastening surface covers the longitudinal sealing seam.

8. A blood pressure cuff in accordance with claim 1 , wherein the chamber section and the handling section are formed integrally with one another.

9. A blood pressure cuff in accordance with claim 1 , wherein the air chamber is made from a tube material in at least some sections.

10. A blood pressure cuff in accordance with claim 1 , wherein the longitudinal sealing seam continues over the entire longitudinal sealing seam extent.

11. A blood pressure cuff in accordance with claim 1 , further comprising:
a first end transverse sealing seam connecting two first end transverse edges of the chamber wall to one another with an airtight connection;
a second end transverse sealing seam connecting two second end transverse edges of the chamber wall to one another with an airtight connection, wherein the longitudinal sealing seam extent along a circumferential direction is from the first end transverse sealing seam to the second end transverse sealing seam.

12. A neonate blood pressure cuff comprising:
a film piece with two longitudinal edges that, with the two longitudinal edges in an overlapped state, extend from opposite directions and overlap as overlapping edges, each of the longitudinal edges having a course comprising at least a first extent, a second extent extending from the first extent at an angle relative to the first extent and a third extent extending from the second extent at an angle relative to the second extent and with two first end transverse edges overlapping each other and two second end transverse edges overlapping each other;
a longitudinal sealing seam connecting the overlapping edges to one another with an airtight connection;
a first end transverse sealing seam connecting the two first end transverse edges to one another with an airtight connection;
a second end transverse sealing seam connecting the two second end transverse edges to one another with an airtight connection, wherein the longitudinal sealing seam follows the course of the overlapping edges to provide a chamber wall with the longitudinal sealing seam course along a circumferential direction from the first end transverse sealing seam to the second end transverse sealing seam and cooperating with the first end transverse sealing seam and the second end transverse sealing seam to form a chamber section with an air chamber having a chamber wall; and
a handling section connected to the chamber section for handling the blood pressure cuff and placing and fastening the chamber section around the arm of a neonate.

13. A blood pressure cuff in accordance with claim 12 , wherein the course of the overlapping edges, and the longitudinal sealing seam forms a zigzag configuration extending in the circumferential direction of the chamber section and the air chamber is closed by forming the transverse sealing seams at upper and lower ends of the chamber section.

14. A blood pressure cuff in accordance with claim 13 , wherein the handling section or the chamber section or both the handling section and the chamber section have a fastening surface on at least one side for fastening the handling section on the chamber section.

15. A blood pressure cuff in accordance with claim 14 , wherein the fastening surface covers the longitudinal sealing seam at least partially.

16. A blood pressure cuff in accordance with claim 13 , wherein the chamber section and the handling section are formed integrally with one another.

17. A neonate blood pressure cuff method comprising the steps of:
providing a film piece with two longitudinal edges having a zigzag shape in at least some sections;
overlapping the two longitudinal edges, with the two longitudinal edges extending from opposite directions, in an overlapped state of the two longitudinal edges, to form a chamber wall of a chamber section of a blood pressure cuff;
forming a longitudinal sealing seam for an airtight connection of the two longitudinal edges, wherein the longitudinal sealing seam has a longitudinal sealing seam extent along a circumferential direction of the air chamber section, wherein each of the longitudinal edges has a course comprising at least a first extent, a second extent extending from the first extent at an angle relative to the first extent and a third extent extending from the second extent at an angle relative to the second extent and with two first end transverse edges overlapping each other and two second end transverse edges overlapping each other;
and closing the chamber section to provide an airtight closure of the chamber section.

18. A blood pressure cuff method in accordance with claim 17 , wherein:
the air chamber is closed by forming a first transverse sealing seam at a first end of the chamber section and forming a second transverse sealing seam at a second end of the chamber section; and
the longitudinal sealing seam extent is from an upper end sealing seam to a lower end sealing seam.

19. A blood pressure cuff method in accordance with claim 17 , wherein the chamber section and a handling section are formed integrally with one another.

20. A blood pressure cuff method in accordance with claim 17 , wherein the longitudinal seali
