[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention resides in a hospital or the like where a gas supply source such as a gas cylinder or a liquefied gas storage tank (CE) is installed at a required place, and a gas supplier is provided with oxygen, laughter and artificial gas. By supplying a medical gas to be administered to an inpatient such as air, etc., the medical gas supply facility for administering the medical gas from the gas supply source to the patient at any time may be used. The present invention relates to a device suitable for measuring the consumption flow rate of supplied medical gas. In particular, hospitals and others can bill patients by accurately and quickly grasping the amount of gas delivered from gas suppliers to gas supply sources and the amount of medical gas actually consumed. Medical gas prescription and medical gas price to be paid to gas supplier are easily calculated and clarified, and medical gas due to gas leakage from medical gas piping, etc. or forgetting to close valve after use, etc. It is intended to detect wasteful consumption of waste gas and secure efficient consumption of medical gas.

[0002]

2. Description of the Related Art In a hospital or the like, a medical gas supply system as illustrated in FIG. 3 is already used to administer a medical gas such as oxygen or laughter to a patient. As the gas supply source a to be installed, a gas cylinder carried by a gas supplier or a liquefied gas storage tank for filling a required liquefied gas carried by a liquefied gas lorry b is used.

[0003] From the gas supply source a, medical gas is categorized according to medical subjects and the like via a gas supply pipe line c, and is supplied to each of the sick rooms d provided in a required number of rooms. Eventually, the medicine is administered to a patient having a predetermined number of members from an outlet e provided in the hospital room d or the like. On the hospital side, small gas flow meters f are respectively installed between the outlet e and the patient as disclosed in the same figure in order to charge each patient for a medication as a medical gas. , The nurse reads each patient gas consumption displayed by this,
Based on this, the bill is charged.

[0004] On the other hand, a medical gas price paid by a hospital to a gas supplier is paid based on the number of gas cylinders delivered by the gas supplier or the filling weight or filling volume from the liquefied gas lorry. That is the current situation. Here, the above-mentioned medical gas delivery amount by the gas supplier and the total consumption amount of the medical gas specified by the doctor and administered to the patient should be originally equal, but actually coincide with each other. Without consumption amount (sales amount,
Dose).

[0005] The difference between the above delivery and consumption is that
A gas leak has occurred due to a defect in the gas supply piping c in FIG. 3, a failure of various auxiliary devices, or an error in the use thereof, or a description or input leak of medical gas administered to a patient. This is because there is no charge, there is a calculation error, and it is not charged, and it is also caused by wasteful consumption due to various reasons such as forgetting to close the valve after using medical gas. is there.

[0006]

According to the above-mentioned conventional example, the purchase price of medical gas at the hospital is paid only based on the delivery amount of the medical gas, and the amount charged to the patient is the consumption amount. Because we charge only by quantity,
Even if there is a difference between the delivered amount and the consumed amount, no consideration is given to the detection of the difference, so the hospital side accepts the absurdity that the hospital will pay for the medical gas not consumed as the dose. Not only do you
Special attention should be paid to the fact that even if gas leaks from various pipes and equipment, etc., it cannot be detected and medical gas is consumed uselessly, and the hospital itself forgets to close the valve after using the equipment.
