Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a medical gas management device for managing oxygen gas and the like stored in hospitals and the like.

(Prior Art) In medical institutions such as hospitals and clinics, oxygen storage equipment is installed within the hospital to ensure that necessary oxygen is always available.

When the remaining amount of oxygen gas in the oxygen storage equipment becomes low, a company is called in to replace the gas cylinder.

(Problem to be solved by the invention) By the way, the amount of M gas used increases rapidly when an emergency patient is admitted, and the amount used suddenly decreases when the patient is discharged from the hospital. Therefore, it is difficult to manage it, and there are many cases where there is not enough remaining capacity when needed.

In view of the above-mentioned circumstances, the present invention provides a medical gas management device that allows a vendor to collectively manage the remaining amount of oxygen gas, etc., thereby ensuring the necessary amount. The purpose is to

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, a medical gas management device according to the present invention includes a sensor that detects the pressure of a bank in which medical gas is stored. a controller that sends out the detection results obtained by the sensor section onto a communication line; a controller that takes in the detection results sent out on the communication line to detect the remaining amount of gas in the bank; It is characterized by being equipped with a center device that performs predetermined processing based on the detection results.

(Function) With the above configuration, the pressure value of the bank is detected, and this is supplied to the center equipment through the path of controller → communication line → center equipment, and the remaining amount of medical gas in the bank, usage frequency, etc. Manage all at once.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of a medical gas management system d according to the present invention.

The medical gas management device shown in this figure consists of a terminal equipment 1 installed on the hospital side and a central management m installed on the information center side.
The information center transmits the amount of oxygen in the oxygen equipment 3 (see Figure 2) installed at the hospital to the information center via the communication line 4, and manages it collectively. .

The terminal device 1 includes a pressure detection section 5, a cylinder information collection section 6, a relay section 7, and a controller 8, and collects the amount of oxygen in the oxygen equipment 3, cylinder information, etc. It is sent onto the communication line 4.

The pressure detection unit 5 includes five pressure sensors 9 to 13, and each oxygen pipe 14.1 provided in the oxygen equipment 3.
When the pressure inside 5.16 becomes below a predetermined value, it is detected 81 and the detection result is supplied to the repeater 7.

In this case, the pressure sensor 9.10 is provided in the oxygen pipe 14 of the left bank 17 constituting the oxygen equipment 3, as shown in the second column, and the bank pressure is set to the values α1, α2 (α
1 〉α2) or less, the remaining amount low value signal S+,
82 and supplies it to the repeater 7. Further, pressure sensors 11 and 12 are installed in the oxygen pipe 15 of the right bank 18 constituting the oxygen equipment 3, and when the bank pressure becomes less than 1st shift α1, α2, the remaining amount is low!
IJs:+, S4 is generated and supplied to the repeater 7. The pressure sensor 13 also outputs the third oxygen equipment;
It is provided in the piping (oxygen piping 16), and when the pressure in this output piping becomes less than the value γ, it is detected and a pressure drop signal S5 is generated and supplied to the relay B7.

In addition, the cylinder information collection I46 includes information about each bank 17 and 18.
It is equipped with a cylinder exchange information switch 19 that is operated when a cylinder is exchanged, and this cylinder exchange/replacement information switch 19 generates a signal indicating the currently used bank, and this signal is transmitted to the relay PJ7. supply to.

When a read command is supplied from the controller 8, the repeater 7 sequentially takes in each signal supplied from the pressure detection section 5 and the cylinder information collection section 6, and supplies the signals to the controller 8.

The controller 8 includes a processing section composed of a microcomputer or the like, an interface connecting this processing section and the repeater 7, and the processing section J! 1! The communication section converts the processing results of the section into communication signals and sends them onto the communication line 4, and deciphers various signals supplied via the communication line 4.

When a signal is output from the repeater 7, it is taken in to generate a communication signal and sent out onto the communication line 4, and various signals supplied via this communication line 4 are transmitted. It decodes the information and controls each part of the terminal device 1.

The central management device 2 provided on the information center side includes a processing device such as a host computer and a display device that displays the processing results of this processing device, and communicates based on a predetermined program. it, I on line 4
controlling the terminal device 1 by sending out a IIl signal;
A communication signal from the terminal device 1 supplied via this communication line 4 is processed to detect whether the remaining amount of oxygen gas in the oxygen equipment 3 in which the terminal device 1 is installed is less than a predetermined value. . Then, when the remaining amount of oxygen gas is less than a predetermined value, this is displayed on the display.

In this case, each pressure sensor 9 to 13 is connected to each bank 17.
．． When the pipe pressure of 18 is below the value α1, α2,
When the output pipe pressure falls below the value γ, the signals SI to S5
occurs, so when the oxygen gas pressure in each bank 17. The switch 2 displays this to inform the staff that the oxygen gas level in the oxygen equipment 3 has become low.

As a result, the person in charge H or the like issues instructions such as replacing the gas cylinder.

Furthermore, in the embodiment described above, when the remaining amount of oxygen gas in the oxygen equipment 3 falls below a predetermined value, this is displayed. Detect and calculate the “usage amount/time”,
It is also possible to predict when the gas cylinder will be replaced.

[Effects of the Invention] As explained above, according to the present invention, the remaining ω of oxygen gas and the like can be managed collectively by the vendor, thereby ensuring the necessary amount.
