Abstract

<P>PROBLEM TO BE SOLVED: To practice kneading a ventilation bag for artificial respiration repeatedly and readily while measuring ventilation volume. <P>SOLUTION: A body 1 of a device for measuring ventilation volume for a ventilation bag for artificial respiration is equipped with a container body 1 which is filled with a liquid and has a transparent part at least at a part and a partitioning member 8 for partitioning the inside of the body of the container into a first chamber 4 and a second chamber. The first chamber 4 communicates with the second chamber through a liquid passing hole 3, and the second chamber communicates with the ventilation bag for artificial respiration through an air hole 2. When the ventilation bag for artificial respiration is kneaded, the air pressure acts on a liquid surface of the second chamber through the air hole 2, and the liquid in the second chamber flows into the first chamber 4 through the liquid passing hole 3. Consequently, the level of the liquid surface of the first chamber 4 fluctuates, and the ventilation volume is measured by using the fluctuations of the level of the liquid surface. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a device for measuring ventilation volume for practice of artificial respiratory ventilation bag.

  Until now, the ventilation measuring device for practice while measuring the ventilation volume of artificial respiration ventilation bag needs to calculate the ventilation volume one time or return the needle because the needle rotates like a clock, mechanically What was being measured, and some were large and expensive, with the mannequin doll's chest moving.

  Normally, a ventilator is used, but artificial respiration ventilation bag is used when the ventilator cannot be used, such as in a bath, hospital inspection, movement, or when a ventilator breaks down. The artificial respirator ventilates the tidal volume by a predetermined amount, but in the artificial ventilation ventilator, the ventilation volume is determined by experience based on the movement of the thorax. It is too expensive to practice artificial ventilation and it is a large doll-shaped object, or the mechanical ventilation measuring device causes the inconvenience that it is necessary to calculate once or to return the needle because the needle rotates clockwise .

  In order to achieve the above object, the present invention comprises a container main body filled with liquid and having a transparent part at least in part, and a partition member for partitioning the container main body into first and second chambers, The first and second chambers communicate with each other through the fluid vent, and the second chamber communicates with the artificial ventilation ventilation bag through the vent hole. Acting on the liquid level in the two chambers, the liquid in the second chamber flows to the first chamber through the liquid passage hole, thereby changing the liquid level in the first chamber. It uses a configuration that uses it to measure ventilation.

  In this invention, it is preferable that the said container main body shall be set as the structure provided with the ventilation volume scale for communicating with the said transparent part and measuring the liquid level of a liquid.

  Further, it is preferable that the transparent portion is provided in association with the second chamber, and the early ventilation volume scale is configured to measure a descending amount of the liquid level of the liquid in the second chamber.

  In addition, it is preferable that the transparent portion is provided in association with the first chamber, and the early ventilation volume scale is configured to measure an increase in the liquid level of the liquid in the first chamber.

  The artificial respiration / ventilation back ventilation measuring device of the present invention is inexpensive and can be used easily because it is simply put liquid in a container, so it can be placed in hospital outpatients, wards, etc., doctors, nurses Can be practiced easily by patient families, medical personnel, and those who use ventilators. In addition, there is an effect that can be used in a class of artificial ventilation ventilation bag. If you practice using this artificial respiration ventilation back ventilation meter, you can see the ventilation with your eyes and practice while feeling some pressure. If connected to a ventilator, the state of ventilation of the ventilator can be seen with the eye, and it can be used for ventilator classes, especially the positive end expiratory pressure (PEEP) can be explained with the eye. Further, when it is not known whether the ventilator is out of order or there is a problem with the ventilator user, it can be determined by connecting to the present invention.

  The best mode of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of an artificial respiration / ventilation back ventilation measuring device according to the present invention, and FIGS. 4 and 5 are cross-sectional views taken along lines AA and BB in the plan view of FIG. ing. In these drawings, an artificial respiration / ventilation / back ventilation measuring device main body 1 includes a container main body 1 filled with liquid and having a transparent part at least partially, and the inside of the container main body in a first chamber 4 and a second chamber 5. A partition member 8 for partitioning, and the first chamber 4 and the second chamber 5 are communicated with each other through the fluid passage hole 2 and the second chamber 5 is communicated with the artificial ventilation ventilation bag 9 through the vent hole. When the artificial respiration ventilation bag 9 is held, the air pressure acts on the liquid level of the second chamber 5 through the vent hole 2, and the liquid in the second chamber 5 enters the first chamber 4 through the liquid hole 3. As a result, the liquid level in the first chamber 4 fluctuates, and the amount of ventilation is measured using the fluctuation in the liquid level.

  FIG. 6 shows an artificial ventilation ventilation bag 9. FIG. 7 is a perspective view in which a liquid is put into the present invention and an artificial ventilation ventilation bag 9 is connected, and FIG. 8 is a perspective view when the artificial ventilation ventilation bag 9 is held in the state of FIG.

  The container body 1 is provided with a first chamber ventilation scale 6 and a second chamber ventilation scale 7 for communicating with the transparent portion and measuring the liquid level.

  The transparent part is provided in association with the second chamber 5, and the previous ventilation volume scale 7 measures the descending amount of the liquid level of the liquid in the second chamber 5.

The transparent portion is provided in association with the first chamber 4, and the pre-ventilation volume scale 6 measures the amount of increase in the liquid level of the liquid in the first chamber 4.

It is a perspective view of an artificial respiration ventilation back ventilation amount measuring device. It is a front view of FIG. It is a top view of FIG. FIG. 4 is a cross-sectional view taken along a line AA in FIG. 3. FIG. 4 is a cross-sectional view taken along the line BB in FIG. 3.
