JPH03143449A - Drip residue scanning apparatus - Google Patents

Abstract

PURPOSE:To automate scanning of residue and alarm operation and to improve accuracy by scanning and alarming residue of a medical fluid based on a change in weight when dripping is performed. CONSTITUTION:In a scanning apparatus part 2, setting of alarm weight and output of an alarm signal when the alarm weight is attained are performed. In an electric system, a signal from a pressure sensor is received and an initial weight and an alarm weight are set by means of a switch and when the alarm weight is attained, an alarm signal is output. In addition, in an alarm part 5, when an alarm signal is received from the scanning apparatus part 2, it is informed by ringing a buzzer that the weight of the dripping medical fluid reaches a set value.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an auxiliary device for monitoring and warning of the remaining amount of an intravenous drug solution, and more specifically to a device for monitoring the remaining amount of an intravenous drip.

2. Description of the Related Art Conventionally, there is a known method for monitoring and warning the remaining amount of an intravenous drug solution, etc., by holding the intravenous drug solution in an aid device shown in FIG. 4 and checking the remaining amount visually by a human.

Problems to be Solved by the Invention The problems described in the prior art are V! It is necessary to constantly monitor and warn the amount of A, which is extremely inefficient, the accuracy is unstable, and monitoring errors are likely to occur. The purpose of this system is to automate the monitoring of the remaining amount of 2-intravenous drug solutions and warning work so that it can be done unattended, improve work efficiency, and eliminate warning points. Easy configuration.More monitoring,
The aim is to provide a device for monitoring remaining drips that improves the accuracy of warnings.

Y! Means for Solving the Problems In order to achieve the above object, the intravenous drip amount monitoring device of the present invention uses a weight measuring device to measure changes in the weight of the intravenous drug solution, etc., and together with the monitoring device, monitors the remaining amount of the intravenous drip. When the set warning amount is reached, the linked warning device will notify you.

Alternatively, a monitoring device or a warning device may be added to the weight measuring device to form an integrated structure.

The intravenous drip remaining amount monitoring device is used by connecting the intravenous drug solution, etc. to a weight measuring device. Then, changes in the weight of the intravenous drug, etc. are measured, and the remaining amount is monitored and warnings are performed without human presence.

Example Examples will be described with reference to the drawings.

The weight measuring device (1) attached to the tip of the intravenous drip amount monitoring device shown in Figures 1 to 3 may be a mechanical type using a scale, or an electric type using a pressure sensor such as a piezoelectric element. The structure is such that it is possible to measure and hold the weight of intravenous medicine, etc.

The monitoring device section (2) sets a warning weight and outputs a warning signal when the warning weight is reached. In the case of a mechanical type, as shown in Figure 2, the weight difference is set by the warning weight contact (3) that is linked to changes in weight, and when the warning weight is reached, the warning weight contact operates the warning contact (4). Use a structure that allows Also,
If it is an electric type, it receives a signal from a pressure sensor, sets the initial weight and warning weight with a switch, and outputs a warning signal when the warning weight is reached.

Further, the warning section (5) receives a warning signal from the monitoring device section (2) and sounds a buzzer or the like to notify that the weight of the intravenous drug solution has reached the set value.

Furthermore, the monitoring device section (2) and/or the warning section (5) may have separate functions and be provided at a remote location to monitor warning signals and the like from the remote location.

Effects of the Invention Since the present invention is configured as described above, it produces the following effects.

In the intravenous drip remaining amount monitoring device of the first aspect, the remaining amount of the intravenous drug solution, etc. can be monitored without the presence of a person.

Furthermore, its accuracy is high, preventing monitoring errors from occurring.
L can do it.

In the intravenous drip 'Pi amount monitoring device holding device of claim 2.3, setting and confirmation work during work can be performed all at once.
