Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for managing an oxygen cylinder provided to a patient receiving home oxygen therapy, and more particularly, to efficiently deliver a required number of oxygen cylinders to a patient when necessary. Oxygen cylinder management system.

[0002]

2. Description of the Related Art For patients suffering from severe chronic respiratory failure, oxygen therapy for inhaling a certain amount of oxygen into the body to avoid organ damage due to respiratory failure has become widespread. In particular,
For patients whose condition is stable and satisfies certain conditions, home oxygen therapy is applied, which provides a facility for inhaling oxygen at the patient's home and enables normal living.

[0003] Patients receiving such home oxygen therapy receive oxygen inhalation at home mainly from an oxygen concentrator driven by a power supply. However, patients receiving home oxygen therapy are required to go to the hospital at least once a month for a doctor's diagnosis.
Receive oxygen inhalation from a portable, lightweight medical oxygen cylinder (hereinafter simply referred to as oxygen cylinder). Alternatively, some patients use oxygen cylinders while taking a bath while at home, or use oxygen cylinders when going out or working.

[0004] As described above, the amount of oxygen cylinder used for home oxygen therapy varies depending on the patient's lifestyle, and varies from patient to patient.
There are up to 30 patients to use.

[0005] Oxygen cylinders are supplied to the homes of patients receiving home oxygen therapy by an oxygen cylinder supply company, subject to the approval of a doctor. Specifically, the oxygen cylinder supply company lends the oxygen cylinder to a filling company that fills the oxygen cylinder with oxygen and / or a delivery company that delivers the oxygen cylinder, and the sales office of the oxygen cylinder supply company requests the oxygen cylinder from the patient. In response to the request or periodically, the filling company and / or the delivery company are instructed to deliver the oxygen cylinder, or the filling company and / or the delivery company deliver the oxygen cylinder at the request of the patient. The filling company and / or delivery company fills the lent oxygen cylinder with oxygen and delivers it to the patient's home. Also, the used oxygen cylinder is collected at the time of delivery, filled with oxygen again, and prepared for subsequent delivery.

Also, the number of oxygen cylinders used by patients has increased,
If the oxygen tank of the filling company and / or the delivery company runs short, the business office is required to add an oxygen cylinder, and accordingly, the business office orders the oxygen cylinder and provides it to the filling company and / or the delivery company.

[0007]

The delivery patterns of the above-mentioned oxygen cylinders can be roughly classified into a regular delivery system in which delivery is periodically made to a patient's home and an on-demand system in which delivery is made in response to a request from a patient. . In the regular delivery method, a filling company and / or a delivery company visit a patient's house when scheduled in advance, and deposit a requested number of oxygen cylinders in the patient's house according to a request of the patient at the time of delivery. Therefore, the timing of cylinder delivery is limited. Therefore, the patient predicts the future usage amount at the time of delivery and determines the required number. In the on-demand method, a request is made irregularly according to the judgment of the patient, and in response to the request, the required number of oxygen cylinders are delivered.

[0008] In the regular delivery system, in order to avoid a situation where oxygen is not present in the oxygen cylinder when the patient wants to use it,
The number of oxygen cylinders delivered per patient tends to increase, and the operation rate of oxygen cylinders decreases. In addition, in the on-demand method, although the minimum required delivery of oxygen cylinders is sufficient, there are cases in which urgent telephone communication is required, and the delivery schedule of the filling company and / or delivery company needs to be changed. Efficiency decreases. In addition, when the number of oxygen cylinders in the patient's home tends to decrease, the worst case is when the number of necessary oxygen cylinders suddenly increases due to a sudden power failure or malfunction of the oxygen concentrator. Occurs.

[0009] After all, conventionally, the number of oxygen cylinders arbitrarily determined between the filling company and / or the delivery company and the patient is merely delivered to the patient's home, and the sales office manages the oxygen cylinder. Was managed using slips, but the actual number of cylinders required was delivered to the patient's home in a timely manner, and the oxygen cylinders were managed to increase the operation rate of the oxygen cylinders without causing oxygen shortages to the patients. Not done.

An object of the present invention is to provide an oxygen cylinder management system which enables efficient delivery of an oxygen cylinder to a patient's house.

[0011]

According to one aspect of the present invention, an oxygen flow setter or respirator attached to an oxygen cylinder measures the oxygen usage by a patient. A memory function for storing as use data is added, and such oxygen use data is transmitted to the oxygen cylinder management server as needed. Such oxygen use data is compiled into a database for each patient by the oxygen cylinder management server, and data on monthly oxygen use is stored for each patient. In addition, this database is linked to patient information such as the cylinder size used by the patient and the filling pressure at the filling station. Based on the accumulated oxygen usage data, cylinder size and filling pressure, the database can be used to determine the past oxygen usage. The future number of oxygen cylinders to be delivered is determined. The management server transmits an oxygen cylinder delivery instruction to the terminal of the business office based on the number of oxygen cylinders delivered. In accordance with the delivery instruction, the sales office causes the filling company and / or delivery company covering the patient's home to deliver the specified number of oxygen cylinders.

According to the above invention, the oxygen cylinder management server makes a database of the amount of oxygen actually used by each patient for each patient, so that the number of subsequent deliveries depends on the number of patients, fillers and / or deliverers. Optimized without any arbitrary agreement between

[0013] The preferred embodiment of the present invention relates to an oxygen flow rate setting device and a respiratory tuning device attached to an oxygen cylinder.
A mobile phone function such as HS is added, and oxygen usage data is transmitted to the oxygen cylinder management server through a communication line every time a patient uses the oxygen cylinder. As a result, the oxygen cylinder management server can dynamically monitor the amount of oxygen used for each patient. Such dynamically changing oxygen consumption is
By comparing the data with the past usage data, it is possible to detect in a timely manner the variation in the oxygen usage for each patient.
Therefore, according to past usage results and detected fluctuation factors,
The number of deliveries can be dynamically changed.

In still another preferred embodiment, the number of deliveries is corrected in consideration of the temperature at the time of using the oxygen cylinder in the patient's house. For example, the reference number of oxygen cylinders delivered based on past use results is corrected to slightly decrease in summer when the temperature is high, and to slightly increase in winter when the temperature is low.

Further, in another preferred embodiment, when the patient travels to a distant place, the oxygen usage data during the travel is transmitted to the management server, and when the oxygen cylinder during the travel becomes insufficient, the oxygen consumption is reduced. The position of the patient is detected using a mobile phone such as a PHS provided in the flow setting device or the respirator,
Instruct the filling and / or delivery company covering the area to deliver oxygen cylinders.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. However, the scope of protection of the present invention is not limited to the following embodiments.
The invention extends to the inventions described in the claims and their equivalents.

FIG. 1 is an overall configuration diagram of an oxygen cylinder management system according to this embodiment. According to this management system, the oxygen cylinder management server 10 installed in the management center, the business office terminal 20 installed in the sales office of the oxygen cylinder supply company, and the oxygen cylinder filling and / or delivery company The installed terminal 30 is connected via a communication line 40 such as a public telephone line, a dedicated telephone line, and the Internet.

As shown in FIG. 1, a filling company and / or a delivery company delivers an oxygen cylinder to a plurality of patients 50 in a service area. The patient 50 receives oxygen inhalation from the oxygen concentrator at home at rest or at bedtime, but in a situation where the oxygen concentrator cannot be used, for example, in a bathroom or on the go, the oxygen cylinder 52 has a flow setting device or respiratory synchronization. Vessel 54
And receive oxygen inhalation. Therefore, the number of oxygen cylinders used by each patient differs depending on the behavior pattern of the patient.

When the patient is receiving oxygen inhalation from the oxygen cylinder, the flow setting device or respirator 54 stores oxygen use data such as a set flow rate and oxygen inhalation time in a built-in memory function, and stores the oxygen use data. The usage data is transmitted to the management server 10 using the communication function as needed.

The oxygen cylinder management server 10 communicates with the communication means 1
00, the oxygen usage data transmitted from the patient is received, and the oxygen usage data collection unit 104 stores the oxygen usage data in the database file 102. The database file 102 contains oxygen prescription data for each patient,
In addition to personal information such as the patient ID, name, address, prescribing doctor, and sales office, data of oxygen cylinder information such as the cylinder size used by the patient and the filling pressure at the filling station are stored.

The management server 10 further has an oxygen cylinder delivery planning means (a kind of software module) 108 for determining the future number of oxygen cylinders to be delivered for each patient based on the accumulated oxygen consumption data. The oxygen cylinder delivery planning means 108 determines the number of oxygen cylinders to be delivered at the next delivery in consideration of the timing of delivery from the filling company and / or delivery company to the patient's home. The determined delivery number is stored in the database file 102 as reference delivery number data. The management server 10 also determines, according to the number of deliveries determined by the oxygen cylinder delivery planning means 108,
It has an oxygen cylinder delivery instruction means 110 for generating a delivery instruction including the delivery cylinder size and the number of deliveries for each patient every day or on the delivery day and transmitting it to the business office terminal 20.

Further, the management server 10 has an oxygen usage monitoring means 106. The oxygen usage monitoring means 106 monitors the oxygen usage data transmitted from the patient as needed, and the oxygen cylinder delivery planning means 108 It detects whether or not a change has occurred in the past usage history considered when determining the number of deliveries. If a change is detected, the oxygen cylinder delivery planning means 10
8, the oxygen cylinder delivery planning means 108 decides to increase or decrease the number of deliveries, or to cancel delivery or temporary delivery.

At the sales office of the oxygen cylinder supply company, the delivery of the oxygen cylinder is instructed to the filling company and / or the delivery company according to the delivery instruction 22 transmitted to the business office terminal 20. In response, the filling company and / or delivery company delivers the designated number of oxygen cylinders to the patient's home. Then, the used oxygen cylinder is recovered.

FIG. 2 is a diagram showing the configuration of the oxygen cylinder and the accessory parts. A pressure gauge 53 is attached to the oxygen cylinder 52 so that the remaining amount of oxygen can be known. A flow setting device 55 for reducing the oxygen pressure and setting the flow rate is attached to the tip of the main stopper of the oxygen cylinder. This flow rate setting device 55
Has a flow rate setting dial, the flow rate can be set by adjusting the dial, and the oxygen of the flow rate set by the dial setting flows out.

Further, a respirator 54 is attached to extend the use time of the oxygen cylinder. Respiratory Synchronizer 5
Numeral 4 has a function of detecting a patient's inhalation and supplying oxygen, and controls the supply of oxygen during inspiration and the supply of oxygen at the time of expiration according to the patient's breathing. Therefore, unnecessary outflow of oxygen at the time of exhalation of the patient can be prevented, and the use time of the oxygen cylinder can be extended as compared with the case where the respirator is not used. Also, the respirator 54
Because it is used when going out, it is battery powered.

FIG. 3 is a diagram showing the internal configuration of the respirator according to the embodiment. The respiratory tuner 54 has a power switch 541 and is turned on by the patient to put the respiratory tuning unit 540 and the flow rate setting unit 542 into operation. The flow rate setting means 542 displays a flow rate value set by, for example, a button switch, and according to the set flow rate, the respiratory synchronization means 5.
The opening degree of the electromagnetic valve incorporated in 40 is controlled. Further, the respiratory synchronization means 540 detects the patient's respiration by a change in pressure, supplies oxygen during inspiration, and stops supply during exhalation.

For example, in the respiratory synchronization control of the embodiment, oxygen is supplied in the first 1/3 of one respiratory period, with the time ratio between inspiration and expiration being, for example, 1: 2. Then, the oxygen supply amount at that time is adjusted to be an amount obtained by dividing the oxygen flow rate (liter / minute) set by the patient by the number of breaths per minute. Therefore, according to the respiratory-tuned oxygen supply, the set oxygen flow rate can be constantly inhaled to the patient regardless of the patient's respiratory frequency.

As a second example of the respiratory synchronization control, the respiratory synchronization means 540 may adjust the flow rate of oxygen supplied during one breath irrespective of the number of breaths of the patient. The oxygen flow rate is determined based on the set flow rate and based on the normal respiratory frequency. In the case of such control, when the patient becomes hypopnea and the respiratory frequency increases, the amount of oxygen inhaled in one minute also increases, so that the patient's hypopnea can be suppressed.

The respiratory tuner 54 of this embodiment further includes an oxygen consumption data memory 544, a portable communication device 546 such as a PHS, and communication instruction means 548.
In the oxygen consumption data memory 544, the time during which the respiratory synchronization means supplies oxygen to the patient and the set flow rate at that time are recorded at a constant sampling cycle. According to the first respiratory synchronization control method described above, the oxygen amount used by the patient can be known by recording the oxygen flow rate set by the patient and the time during which the respiratory synchronization means is operating. In the case of the above-described second respiratory synchronization control method, if the set oxygen flow rate and the number of breaths are recorded, the amount of oxygen used by the patient can be known.
Regardless of the respiratory synchronization control, it is only necessary to record usage data so that the amount of oxygen used by the patient can be recognized.

In response to the instruction from the transmission instruction means 548, the portable communication device 546 transmits the data stored in the oxygen consumption data memory 544 to the management server via the communication line as shown in FIG. Send to 10.

FIG. 4 is a diagram showing the use time of the oxygen cylinder and the transmission timing of the oxygen use amount data. In this example, set the flow rate at rest X liters / minute while on the go,
This is an example in which an oxygen cylinder is used from time t0 to t3, and thereafter, the flow rate during exercise such as walking is set to Y l / min, and the oxygen cylinder is used from time t4 to t6 and from time t7 to t8.

The oxygen reference amount data memory 54 shown in FIG.
4 stores usage data at a constant sampling cycle. Then, the transmission instructing means 548 requests the portable communication device 546 to transmit the usage data at a timing when a period dt longer than the sampling period elapses after the power switch is turned on. Further, the transmission instruction means 54
No. 8 requests transmission of usage data whenever the power switch is turned off.

Therefore, as shown in FIG. 4, at rest, at times t1 and t2 when the cycle dt has elapsed since the power was turned on.
At the time of power off,
Oxygen usage data is transmitted even though the cycle dt has not elapsed. By transmitting at such a timing, the oxygen usage data used by the patient is reliably transmitted to the management server 10.

From time t4 to time t6 at the time of exertion, the time t5 when the cycle dt has elapsed since the power was turned on, and the time t5 when the power was turned off.
At timing 6, oxygen usage data is transmitted. Further, from the time of exertion t7 to the time t8, the oxygen usage data is transmitted at the timing of the power-off time t8.

By transmitting the usage data at such a timing, the past recorded oxygen usage data can be reliably transmitted to the management server 10 while the respirator 54 is being driven by a battery. it can. It should be noted that even if the respirator is not turned off and left as it is, the cycle d
After t, the oxygen usage data is transmitted.

FIG. 5 is a diagram showing an example of the database of the management server. The database file 102 of the management server 10 is calculated from the patient's personal information such as the patient's name, address, sales office, charge supplier and / or delivery company, doctor in charge, cylinder size to be used, and the past oxygen consumption data. Information on the history of the used oxygen (liter / month) and information on the reference number of deliveries on the next delivery date calculated from the history of the amount of oxygen used. In the example of the database of FIG. 5, some of the information is omitted, and the patient ID
For each of them, the sales office in charge, the filling company and its filling pressure, the history of oxygen consumption, the cylinder size, and the standard number of deliveries are shown.

By receiving the above-mentioned oxygen usage data, the oxygen cylinder delivery planning means 108 in the management server can calculate the past oxygen usage history for each patient. Therefore, in order to calculate the required number of oxygen cylinders to be delivered from the oxygen consumption history, the filling pressure and the cylinder size of the filling station in charge of the patient are referred to. In other words, the filling stations have different filling pressures due to the filling equipment.
When the filling pressure is high, the amount of oxygen that can be charged into one oxygen cylinder increases, and when the filling pressure is low, the amount of oxygen charged decreases. Therefore, it is necessary to calculate the number of cylinders to be delivered according to the filling pressure of the filling station in charge of the patient. Furthermore, if the cylinder size is large, the amount of charged oxygen naturally increases, and if the cylinder size is small, the amount of charged oxygen decreases.

For example, 15M is added to a 2 liter oxygen cylinder.
When oxygen is filled with Pascal, the amount of oxygen charged is 30
Although it becomes 0 liters, the amount of oxygen becomes 260 liters when the same oxygen cylinder is filled with 13M pascal. If the oxygen cylinder size is different, the oxygen amount is proportionally different.
In consideration of these, the oxygen cylinder delivery planning means 108
According to Boyle-Charles' law, the required number of oxygen cylinders that match the past oxygen consumption is calculated. Then, a reference delivery number is determined by adding a certain surplus number to the required number of oxygen cylinders.

Further, the oxygen cylinder delivery planning means 108 includes:
It is preferable to correct the reference number of deliveries according to the temperature of the delivery season. The oxygen flow rate is indicated by the doctor's prescription. Thus, the patient will use the oxygen cylinder at the prescribed oxygen flow rate. In this case, if the temperature in the use environment is high, the amount of oxygen flowing out of the compressed oxygen cylinder increases, and if the temperature is low, the amount of oxygen flowing out decreases. Therefore, in summer when the temperature is high, correction is made to slightly lower the standard number of deliveries, and in winter when the temperature is low,
Correction is made to slightly increase the reference delivery number.

FIG. 6 is a flowchart showing the operation of the oxygen cylinder management system according to this embodiment.
While the patient receiving home oxygen therapy is using the oxygen cylinder, the portable communication device provided in the respiratory synchronizing device transmits the oxygen usage data to the management server 10 (S10). The oxygen usage data collection unit 104 in the management server stores the received oxygen usage data in the database file 102 for each patient (S12). By repeating the above steps S10 and S12, it is possible to accumulate oxygen usage data for the past, for example, several months of the patient. Then, the oxygen cylinder delivery planning means 108
However, the reference delivery number is determined by the above algorithm (S14). Thereby, the number of oxygen cylinders to be delivered to the patient's home by the filling company and / or the delivery company is determined. If the delivery frequency is irregular, the reference number of deliveries for each delivery date is determined according to the delivery schedule of the filling company and / or delivery company.

The above-mentioned standard delivery number is determined by the oxygen cylinder delivery instruction means 110 of the management server by sending the delivery instruction 22 to the business office terminal 20, so that the oxygen cylinder can be delivered more efficiently than before. It is possible to provide the required number of tubes for each patient, while increasing the operating rate of the oxygen cylinder.

In the present embodiment, the oxygen consumption data of the patient is further transmitted from the oxygen flow setting device or the respirator.
It is transmitted to the management server as needed (S16). This latest usage data is stored in the oxygen usage data collection unit 10 of the management server.
4, the oxygen usage monitoring means 106 monitors whether there is a large change in the oxygen usage while comparing the current oxygen usage with the past history. Then, when it is detected that the usage amount is significantly different from the past average usage amount, the oxygen usage monitoring unit 106 notifies the oxygen cylinder delivery planning unit 108 of the detection result. In response, the increase / decrease in the number of deliveries, the suspension of delivery, and extraordinary delivery are determined (S20), and the oxygen cylinder delivery instruction means 110 transmits the delivery instruction 22 to the business office terminal 20 according to the determination (S22). .

FIG. 7 is a diagram showing an example of the delivery instruction. The delivery instructions to the sales office of the oxygen cylinder supplier include:
A list of delivery cylinder sizes and delivery numbers for patients handled by the sales office is listed for each filler and / or delivery company. Therefore, upon receiving the delivery instruction (S24), the sales office delivers the data to the filling company and / or the delivery company terminal by transmitting data via the network 40, or to the filling company and / or the delivery company by telephone or fax. The patient, address, cylinder size, and number to be delivered are notified and delivery is instructed (S26). According to the delivery instruction, the filling company and / or the delivery company delivers the oxygen cylinder to the patient's home and collects the used cylinder.

At the time of delivery and collection, the filling company and / or the delivery company inputs the barcode printed on the oxygen cylinder, inputs the patient information of the delivery destination, and transmits the data from the terminal 30 to the management server 10. Can be used for oxygen cylinder management data. In other words, by managing the state of residence of the oxygen cylinder at the filling station, it is possible to manage the optimal number at the patient's home and to manage the optimal stock quantity at the filling company and / or the delivery company.

As a modification of the above embodiment, a case where a patient travels to a remote place will be described. When traveling to a remote place, the patient registers in advance the travel date and the number of oxygen cylinders to be carried in the management server via the business office. The number of cylinders to be carried depends on the patient's prediction, but the amount of oxygen used varies depending on the situation at the destination.

In such a case, oxygen consumption data during travel is transmitted to the management server one by one from the respirator attached to the oxygen cylinder of the patient. The management server 10 calculates the number of cylinders to be delivered to the destination and the date and time (delivery timing) from the oxygen consumption data. Utilizing the function of the PHS incorporated in the respirator, the destination of the patient is detected, and the delivery of an oxygen cylinder is instructed to a filling company and / or a delivery company covering the area. Even in such a case, it is preferable to instruct the delivery at the optimal timing in consideration of the filling pressure at the filling place at the destination, the temperature at the destination, and the like.

In the above embodiment, in the transmission step S10 of the oxygen usage data in FIG. 6, the data is transmitted using the communication line, but the history of the oxygen usage for determining the initial reference delivery number is stored. There is no need to send data sequentially while the oxygen cylinder is in use for storage. The data for several months may be recorded on a recording medium such as an IC card or a floppy (registered trademark) disk and delivered offline to a management center via a business office. Alternatively, data compiled by the office terminal may be transmitted to the management center. However, in the transmission step S16 in FIG. 6, it is necessary to inform the management server of the oxygen usage data of the patient in real time.
Transmission via a communication line is required.

In the above embodiment, the memory for storing the oxygen consumption data and the portable communication device for transmitting the data to the management server are built in the respiratory synchronizer. If not used, a memory and a portable communication device may be built in the flow setting device. What is necessary is just to provide in the flow setting means which can detect the use time of the oxygen cylinder and its flow rate, such as a respiratory synchronizer and a flow setting device.
