Abstract

A blood pressure monitor kit suitable for use in emergency scenarios such as cardiopulmonary arrest situations. The kit includes a catheter for insertion in the femoral artery of the patient, a transducer arranged to receive blood pressure signals from the catheter and operative to convert the blood pressure signals into electric signals; a housing; a monitor mounted in the housing and including electric circuitry arranged to receive the electric signals from the transducer and operative to generate at least one display indicative of a condition of the patient'"'"'s blood pressure; a battery positioned within the housing and operative to power the electric circuitry; a switch associated with the housing for connecting the battery into the electrical circuitry to power the circuitry; and a securement device on the housing operative to secure the housing to a patient'"'"'s body at a location proximate the location of the catheter insertion. The entire kit is packaged in a container which totally envelops the catheter, transducer, and monitor and forms a sealed, sterile package which may be opened upon demand. The kit is intended for one time use and is suitably disposed of after the single use.

Claims

a transducer carried by the housing and positioned in operative association with the operative portion of the conduit and operative to receive blood pressure signals from the operative portion of the conduit and convert the blood pressure signals into electrical signals;

a monitoring device mounted in the housing and including electric circuitry arranged to receive the electrical signals from the transducer and operative to generate at least one display indicative of a condition of the patient'"'"'s blood pressure;

a battery positioned within the housing and operative to power the electric circuitry;

a switch associated with the housing for connecting the battery into the electric circuitry to power the circuitry;

securement means on the housing operative to secure the housing to a patient'"'"'s body at a location proximate the location of the catheter insertion; and

a reservoir containing a flushing solution and having an outlet for communication with the conduit to flush the conduit.

2. A monitor according to claim 1 wherein the kit further includes a container totally enveloping the catheter, transducer and monitoring device and forming a sealed, sterile package which may be opened upon demand to provide a disposable blood pressure monitor kit for emergency use applications.

3. A blood pressure monitor kit according to claim 1 wherein the conduit further includes a flushing portion communicating with the operative portion and the outlet of the reservoir communicates with the conduit flushing portion.

4. A monitor according to claim 3 wherein the kit further includes a container totally enveloping the catheter, transducer and monitoring device and forming a sealed, sterile package which may be opened upon demand to provide a disposable blood pressure monitor kit for emergency use applications.

5. A miniaturized blood pressure monitor kit according to claim 3 wherein the kit further includes a stopcock at a free end of the conduit flushing portion, the reservoir outlet communicating with the stopcock to flush the conduit.

6. A blood pressure kit according to claim 5 wherein the kit is totally enveloped in a container and the kit further includes a tray positioned removably within the container and containing the catheter.

7. A kit according to claim 6 wherein the kit includes a plurality of catheters of varying sizes and configurations and all of the catheters are positioned in the tray so as to provide a selection of catheters for use with the monitor.

8. A kit according to claim 5 wherein the kit further includes a further stopcock in the conduit between the catheter and the conduit operative portion.

13. A miniaturized blood pressure monitor kit according to claim 7 wherein:

the container defines a lower level below the tray and the transducer and monitoring device are positioned in the lower level of the container beneath the tray.

9. A method of monitoring the blood pressure of a patient in an emergency situation comprising the steps of:

providing a disposable sterile blood pressure monitor kit including a housing;

a catheter adapted to be inserted into a blood vessel of the patient;

a conduit formed of a tubular material and having a flexible connector portion and an operative portion carried by the housing and communicating with the connector portion;

a transducer carried by the housing, juxtaposed to the operative portion of the conduit, and operative to receive blood pressure signals from the operative portion of the conduit and convert the blood pressure signals into electrical signals;

a battery positioned in the housing;

a switch on the housing connected to the battery;

a monitoring device positioned in the housing, powered by the battery, controlled by the switch, and including electric circuitry arranged to receive electrical signals from the transducer and operative to generate at least one display indicative of an aspect of the patient'"'"'s blood pressure;

securement means on the housing operative to secure the housing to a patient'"'"'s body at a location proximate the location of the catheter insertion; and

a reservoir containing a flushing solution and having an outlet for communication with the conduit;

moving the kit to a location proximate a blood vessel of the patient;

inserting the catheter into the blood vessel;

securing the housing to the patient'"'"'s body at a location proximate the location of the catheter insertion; and
