Catheter Connector for Measurement of Physiological Signals
The present invention relates to a connector, for use with a catheter provided with a catheter valve, comprising a liquid channel, for transporting a liquid from a first to a second end of the connector, or vice versa, a first coupler, provided on the first end of the connector, to couple the connector and the catheter, a second coupler, provided on the second end of the connector, to couple the connector and a liquid administering—and/or measuring device, a pin-shaped part, from the first end of the connector extending in substantially axial direction, to open the catheter valve when the connector is coupled to the catheter.
1 . Connector, for use with a catheter provided with a catheter valve, the connector comprising:
a liquid channel, for transporting a liquid from a first to a second end of the connector;
a first coupler, provided on the first end of the connector, to couple the connector and the catheter;
a second coupler, provided on the second end of the connector, to couple the connector and a liquid administering and/or measuring device;
a pin-shaped part, from the first end of the connector extending in substantially axial direction, to open the catheter valve when the connector is coupled to the catheter.
2 . The connector according to claim 1 , wherein the pin-shaped part is hollow.
3 . The connector according to claim 1 , wherein the pin-shaped part extends beyond the catheter valve when the connector is coupled to the catheter.
4 . The connector according to claim 1 , wherein one of the first and second coupler comprise rotary couplings.
5 . The connector according to claim 1 , wherein the pin-shaped part has a length between 5 and 50 mm, and a diameter between 0.5 and 2.5 mm.
6 . The connector according to claim 1 , further comprising an electric conductor which extends from the channel to an outside of the channel, to connect a measuring device.
7 . The connector according to claim 1 , connected to and in fluid communication with a liquid administering device.
8 . The liquid administering device of claim 7 further comprising an electric conductor, which extends from the channel to an outside of the channel, to connect a measuring device.
9 . A connector for use with a catheter provided with a catheter valve, the connector comprising:
a first coupler, provided on the first end of the connector, to couple the connector and the catheter;
an at least partly electrically conductive pin-shaped part, from the first end of the connector extending in substantially axial direction, to open the catheter valve when the connector is coupled to the catheter;
an electric conductor, conductively coupled to the pin-shaped part, which extends from the connector, to connect a measuring device.
10 . The connector according to claim 9 , also comprising a measuring device, such as a electrocardiograph.
