FR2672216A1 - Monitoring hourly diuresis on a monitor - Google Patents

Abstract

The invention relates to a device which permits a monitoring of hourly diuresis, without risk of contact with the urine and without recording on a register. The device consists of a sheath (1) enclosing, by means of its attachments (2), the connection pieces (3) and (4), thereby permitting a reconnection of the connection pieces (3) and (4) in the event of an accidental disconnection. The reservoir (5) is equipped with a level gauge (6) which sends an electrical signal to a monitor (8) to provide information on the volume of the urine (9). The monitor (8) is characterised by twenty four diodes (14) which display hour by hour, dial (14) by dial, a volume and an hour corresponding to a monitoring of hourly diuresis over 24 hours. Upon each change-over from one dial to another, a valve (10) permits the transfer of the recorded urine (9) into a bag (11). Application in all hospital environments.

Description

MONITORING OF A TIME DIURESE ON MONITOR
The present invention relates to a method which makes it possible to monitor an hourly diuresis, in closed circuit, on a display monitor.

The monitoring of an hourly diuresis is traditionally carried out by emptying into a reusable, mobile container, made of graduated glass for this purpose.

This has the consequence of - compromising the sterility of the closed system.

- Increase the risk of accidental breakage of the
container.

- Increase the risk of contamination by spraying
of urine on the manipulator's hands and his surroundings
really.

- To compel medical personnel to register, on a
register intended for this purpose, the hourly volume reached
as well as its total accumulation over twenty four hours.

Some of these graduated containers are for single use operating in a closed circuit by connection to a bladder probe. This does not eliminate the fact of an accidental disconnection with the risk of compromising the sterility of a desired closed system as well as of contaminating the environment during the incident. This system also forces medical personnel to record the hourly volume reached by urine as well as its total accumulation over twenty four hours.

The method according to the invention overcomes these drawbacks.

It comprises, as a first characteristic, a transparent sheath of flexible pleated plastic, provided at each end with self-adhesive fasteners, through which are introduced the connection of a bladder probe and the connection of the tubing of a rigid plastic tank.

These two fittings are then connected to each other and the fasteners glued or joined. During an accidental disconnection, the sheath will deploy in length, about 20 centimeters, thus guaranteeing the possibility of reconnection in a closed circuit without compromising sterility thus avoiding direct contact with urine.

As a second characteristic, it includes a completely sealed urine collection set.

The upper part of this assembly is a tight rigid plastic tank connected by its upper tube to the flexible plastic sheath, mentioned in the first characteristic, which itself is connected to the bladder probe. The transparency of this tank allows the appearance of collected urine to be controlled.

A level gauge, located on the inside length of the tank, reflects an electrical signal to a monitor when the urine is rising, which allows precise information to be displayed on the volume of urine reached in this tank.

The monitor, designed from a microprocessor, displays after 60 minutes a memorization of the volume reached in milliliters on a first dial. The medical staff then manually opens a tap located on the lower part of the tank which allows the contents to flow into a flexible and waterproof plastic bag.

After twenty four hours, the microprocessor informs the medical personnel of the volume reached hour by hour on twenty four different dials. Each dial corresponds to a monitoring of an hourly diuresis.

An additional dial calculates and stores the sum of each dial hour after hour and continuously shows the cumulative volumes and time.

The monitor can be connected to a printer in order to keep all the information on the monitoring of an hourly diuresis in the patient's file.

The accompanying drawings illustrate the invention - Figure 1 shows a section of the system
before use.

- Figures 2 and 3 show in section part of the
system during use.

- Figure 4 shows in section the general device
according to the invention.

Referring to Figure 1 the method comprises a sheath (1) of transparent flexible plastic, open at each end. By way of nonlimiting example, the size of the sheath (1) can be of the order of - 20 centimeters for the length, - 2 centimeters for the diameter.

At each end of this sheath (1) is fixed a fastener (2) glued or welded to the half circumference of the sheath (1), leaving two self-adhesive tabs (2) free. By way of non-limiting example, the dimension of the fasteners (2) can be of the order of - 10 centimeters for the length, - 2 centimeters for the width.

Referring to Figure 2, the flexibility of the sheath (1) is important so that it can be pleated during the introduction of the fittings (3) and (4). The fasteners (2) allow a hermetic closure.

Referring to Figure 3, during an accidental disconnection the sheath (1) deploys in length, about 20 centimeters, thus ensuring reconnection in a closed circuit without compromising sterility, avoiding direct contact with urine.

With reference to FIG. 4, the method consists of a tank (5) made of rigid, transparent and leaktight plastic with a non-limiting volume of the order of 200 milliliters, connected by its upper tube (4) to the probe. bladder (3). A level gauge (6) runs along the largest interior height of the tank (5) and is connected by an external cable with electrical plug (7) to the monitor (8). Whatever the basic principle of gauge (6) it then sends an electrical signal, corresponding to the rise of urine (9) in the tank (5) which is transformed by the electronics of the monitor (8) into a direct reading in milliliter.

A rigid plastic drain valve (10) with manual opening and closing is joined between the rigid tank (5) and a flexible and resistant plastic bag (11).

This tap (10) allows, every hour, to transfer the urine (9) into a flexible, resistant and waterproof plastic bag (11). Its non-limiting volume can be of the order of 4,000 milliliters.

This drain valve (10) is only put in the open position once the hourly urine (9) has been memorized by the monitor electronics (8). According to particular embodiments, the drain valve (10) can be replaced by an automated opening-closing system, managed and controlled by the electronics of the monitor.
The monitor (8), designed from a microprocessor, manages the following functions - A switch (12) for operating
ON OFF.

- A dial (13) with liquid crystal display which indicates
the time and which serves as a starting point for the microprocessor
to manage and control subsequent information.

- Twenty four dials (14) with liquid crystal display
which each correspond to the monitoring of a diuresis
24 hour schedule. Each dial (14) indi
than reading an hour and a volume.

- A dial (15) with liquid crystal display which follows
hour after hour the evolution of each dial (14), which
continuously add and display cumulative volumes
and time.

- An adapter (16) for connection to a printer.

- An electrical plug cable (17) which allows connection
at the level gauge (6).

- An electrical plug socket (18) which allows the connection
specifically to the 220 Volt sector.

By way of non-limiting example, the dimensions of the monitor (8) can be of the order of - 20 centimeters for the length, - 12 centimeters for the width, - 3 centimeters for the thickness.

By way of non-limiting example, the weight of the monitor is of the order of 250 grams.

The device according to the invention is particularly intended for monitoring an hourly diuresis for all of the hospital centers.
