Patient monitoring system
A patient monitoring system has a patient monitor and a patient sensor connected to the patient monitor by a measurement cable. An electrical connector between the end of the measurement cable and the patient monitor has a male part with a shroud around a set of pins and a female part with a recess around a set of openings. An annular seal is provided between a surface of the shroud and a surface of the recess.
1. A patient monitoring system, comprising:
a patient monitor;
a patient sensor;
a measurement cable coupled to the patient sensor, for removable connection to the patient monitor at an end of the measurement cable; and
an electrical connector between the end of the measurement cable and the patient monitor, wherein the electrical connector comprises:
a male part comprising a set of pins and an annular shroud surrounding the set of pins;
a female part comprising a set of pin openings each for receiving a respective pin of the set of pins, and a recess surrounding the set of pin openings for receiving the annular shroud; and
an annular seal between a surface of the shroud and a facing surface of the recess, wherein the annular seal is between an outer surface of the shroud and an inner surface of the recess.
2. The patient monitoring system as claimed in claim 1 , wherein the male part is part of the measurement cable and the female part is part of the patient monitor.
3. The patient monitoring system as claimed in claim 1 , wherein the annular shroud extends at least to the ends of the pins of the set of pins.
4. The patient monitoring system as claimed in claim 1 , wherein the annular shroud and recess are circular or non-circular, wherein the male part and the female part are connectable with only one relative angular orientation.
5. The patient monitoring system as claimed in claim 1 , wherein the annular seal comprises a set of one or more radially protruding lips which are adapted to compress radially when the male part is received in the female part.
6. The patient monitoring system as claimed in claim 1 , wherein the annular seal is a silicone seal.
7. The patient monitoring system as claimed in claim 1 , wherein the annular seal is an Ethylene Propylene Diene Monomer, EPDM, seal.
8. The patient monitoring system as claimed in claim 6 , wherein the annular seal is integrally formed using 2K molding.
9. The patient monitoring system as claimed in claim 1 , wherein the patient sensor is for vital signs measurement.
10. The patient monitoring system as claimed in claim 1 , wherein the annular seal is connected to a radially outwardly facing surface of the shroud.
11. The patient monitoring system as claimed in claim 1 , wherein the annular seal is connected to a radially inwardly facing surface of the recess.
12. A sensor cable system for connection to a patient monitor, wherein the sensor cable system comprises:
a patient sensor;
a measurement cable coupled to the patient sensor;
a male connector at an end of the measurement cable comprising a set of pins, and an annular shroud surrounding the set of pins;
a female connector at an end of the measurement cable comprising a set of pin openings, and a recess surrounding the set of pin openings; and
an annular seal, wherein the annular seal is between an outer surface of the shroud and an inner surface of the recess.
13. A patient monitor for connection to a patient sensor by means of a measurement cable, wherein the patient monitor comprises:
a male connector comprising a set of pins, and an annular shroud surrounding the set of pins;
a female connector comprising a set of pin openings, and a recess surrounding the set of pin openings; and
an annular seal, wherein the annular seal is between an outer surface of the shroud and an inner surface of the recess.
14. The sensor cable as claimed in claim 12 , wherein the annular shroud extends at least to the ends of the pins of the set of pins.
15. The sensor cable as claimed in claim 12 , wherein the annular seal is connected to a radially outwardly facing surface of the shroud.
16. The sensor cable as claimed in claim 12 , wherein the annular seal is connected to a radially inwardly facing surface of the recess.
17. The patient monitor as claimed in claim 13 , wherein the annular shroud extends at least to the ends of the pins of the set of pins.
18. The patient monitor as claimed in claim 13 , wherein the annular seal is connected to a radially outwardly facing surface of the shroud.
19. The patient monitor as claimed in claim 13 , wherein the annular seal is connected to a radially inwardly facing surface of the recess.
