Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home medical device, and more particularly to a home medical device having a function of exchanging information with a postcard.

[0002]

2. Description of the Related Art As a home medical device, an oxygen concentrator used in home oxygen therapy is a device that concentrates oxygen in the air to 40% and supplies it. The oxygen supply flow rate is 0 to 6 liters per minute in terms of 100% concentration. By using this device, oxygen therapy can be performed at home without going to the hospital.

The oxygen flow rate during treatment is determined for several days to several weeks after hospitalization, and is determined on the basis of the improvement of subjective symptoms while observing arterial blood gas analysis, red blood cell concentration, heart rate, blood pressure and the like. In addition, the decision as to whether or not oxygen therapy is required is made by a licensed hospital, and the hospital makes an arrangement with an oxygen supply equipment supplier. The contractor rents the oxygen concentrator to the hospital, and the hospital lends it to the patient. The hospital supervises and administers home oxygen therapy to patients.

Further, there is a constant velocity exercise machine (Cybex machine) which is not currently used as a home medical device but is used in the field of knee rehabilitation. Training for recovery of knee function requires a long period of time, and it is expected that the device will be used as a home medical device because it requires a patient to visit the hospital. Cybex machine
Is a device that can perform uniform muscle strength training and muscle strength measurement at the same time. Since the speed of knee bending and stretching can be controlled, the speed does not change even if any force is applied, and the servo
The force applied by using Ta returns to the person who added it as a reaction force. In other words, strength training can be done with the power that suits each individual.

On the other hand, as a system using a postcard,
Notification of electricity charges used by electric power companies and after-sale equipment
As you can see from the examples of postcards for service and usage surveys, humans read the data on the electricity meter and wrote it down,
If you want to create a postcard by sending it to each household and send it to each household,
In some cases, the user fills in the applicable items in the device usage status survey and sends it to the manufacturer. Also, when the manufacturer of the device usage survey postcard wants to change the parameters of the device, the user who sent the postcard wrote the instructions to the user and sent the postcard. Instruct the device to see the contents of the postcard. In this way humans
Fill in the postcard with data to enter into a table, etc., and look at the data that the person who received the postcard filled in.
I was typing in the database.

[0006] Therefore, a method for saving labor by notifying with a postcard with a machine-readable code has been proposed in several application fields, for example, Japanese Patent Laid-Open No. 2-278.
Japanese Patent Laid-Open No. 490 discloses a method of inputting an irregular accident list in a card check system.
Japanese Patent No. 8668 discloses an automatic cash collecting machine capable of saving labor.

[0007]

The above-mentioned conventional home medical device is rented from the hospital by the hospital to the patient and lent it to the patient. The current situation is that it does not arrive. Since the hospital does not have a system for periodically grasping the status of home therapy for each patient, the treatment policy had to be decided based on the limited information when the patient contacted.

The home medical device of the present invention has been made in view of such a problem, and the purpose thereof is to suppress the increase of the cost burden on the hospital and the patient side and to enhance the management of home medical care. It is to provide a home medical device that can be operated.

[0009]

In order to achieve the above object, the home medical device of the present invention uses the operating status data of the medical device when it is determined that a certain period has elapsed. Recording means for recording on a postcard sent to the hospital as a readable code, reading means for reading a machine readable code indicating a change instruction recorded on the postcard from the hospital, and a medical device based on the read machine readable code. And a changing unit for changing the setting parameter.
