Abstract

The present invention provides a modular system for mounting one or more medical devices on an IV pole at a patient'"'"'s bedside. The system comprises a support plate, and at least one modular interconnection receptacle adapted to be detachably mounted on the support plate and adapted to receive a medical device. In one embodiment, the interconnection receptacle has electrical connection means serving as an electrical conduit between the medical device and a monitor. The means for attaching the medical device to the interconnection receptacle has a greater retention force than the means for attaching the interconnection receptacle to the support plate. Thus, in response to a threshold force on the patient line connected to the medical device, the interconnection receptacle breaks free of the support plate while the medical device remains attached to the interconnection receptacle. This maintains fluid connection to the patient and electrical connection to a monitor in the case of a medical device, such as a pressure transducer.

Claims

1. A system for holding one or more medical devices, comprising:

(a) a support;

(b) at least one modular interconnection receptacle adapted to be detachably mounted on the support and adapted to receive the medical device;

(c) the modular interconnection receptacle having attachment means for receiving and holding the medical device and means for detaching from the support in response to a threshold force on the medical device, the force required to break the attachment between the medical device and the interconnection receptacle being greater than the force required to detach the interconnection receptacle from the support.

7. A system according to claim 1 or 2, wherein the support has a cut out hole with a dimension corresponding to the outer dimension of the interconnection receptacle and a tab extending into the hole for mating with a tab on the interconnection receptacle for detachably mounting the interconnection receptacle on the support.

8. A system according to claim 1 or 2, wherein the support is provided with more than one cut out hole for connecting more than one modular interconnection means.

9. A system according to claim 1 or 2, wherein the interconnection receptacle has slots formed therein which mate to tabs on the medical device, the tabs on the medical device adapted for one hand manipulation to attach and detach the medical device from the interconnection receptacle.

10. A system according to claim 1 or 2, wherein the support has a protective cover pivotally mounted on the support, the cover being pivotal to a closed position to cover the interconnection receptacle and to an open position to expose the interconnection receptacle, the cover providing a hood to protect back side cable connections to the interconnection receptacle from fluid splash when the cover is in the open position.

2. A system for mounting one or more medical devices near a patient, comprising:

(a) a support;

(b) at least one modular interconnection receptacle adapted to be detachably mounted on the support and adapted to receive the medical device;

(c) the modular interconnection receptacle having attachment means for receiving and holding the medical device and means for detaching from the support in response to a threshold pulling force on a line connecting the medical device to the patient, the attachment means having a retention force greater than the retention force of the detachment means;

(d) the interconnection receptacle having electrical connection means serving as an electrical conduit between the pressure transducer and a pressure monitor.

3. A system according to claim 2, wherein said electrical connection means comprises first electrical contact means for making electrical connection with the medical device and second electrical contact means for connecting an electrical cable leading to the monitor.

4. A system according to claim 3, wherein wiring from the first electrical contact means to the second electrical contact means includes a shunt resistor connecting positive excitation to negative excitation, the electrical connection means between the medical device and the interconnection receptacle thereby providing monitor recognition of the medical device when the interconnection receptacle is connected to the electrical cable leading to the monitor.

6. A system according to claim 2, wherein the medical device is a pressure transducer, the attachment means has sealing means to provide an airtight seal between the pressure transducer and the interconnection receptacle when the pressure transducer is attached, and the interconnection receptacle has a port formed therein communicating with the pressure transducer to vent the pressure transducer to atmospheric pressure and for use in calibrating the pressure transducer.

5. A system according to claim 5, wherein the first electrical contact means comprises spring pins which contact a ceramic circuit board on the medical device.

11. A pressure transducer assembly for monitoring pressure in a fluid, comprising:

(a) a housing comprising a flow-through fluid chamber with inlet and outlet ports and an open chamber covered by a shroud;

(b) a pressure transducer means mounted in the open chamber having a diaphragm coupled to the flow-through chamber for sensing fluid pressure pulses within a fluid in the flow-through chamber and having means for converting the sensed pressure pulses into electrical signals;

(c) attachment means on the housing adapted to attach the housing to an interconnection receptacle to create a closed chamber within the shroud upon attachment and wherein upon attachment the pressure transducer is electrically coupled to electrical connection means on the interconnection receptacle, the interconnection receptacle being adapted to serve as an electrical conduit between the pressure transducer means and a pressure monitor.

12. A pressure transducer assembly according to claim 11, wherein the attachment means comprises tabs that mate with slots or tabs on the interconnection receptacle, wherein the tabs are adapted for one hand manipulation to attach and detach the assembly from the interconnection receptacle.

13. A pressure transducer assembly according to claim 11, wherein the pressure transducer means vents to the inside of the shroud and the shroud when couple to the interconnection receptacle forms an airtight chamber with the interconnection receptacle providing a vent to atmospheric pressure and means for calibrating the pressure transducer by applying a pressure to the inside of the shroud covered chamber.
