Description

  The present invention can manage nutrition management of hospitalized patients or patients who have dietary restrictions in a batch by a nutrition management server by accurately and electronically grasping the patient's dietary intake. The present invention relates to a hospital food intake confirmation system capable of collecting data.

As a technique for performing nutrition management of an inpatient using a computer, there is a technique as shown in Patent Document 1, for example. In the technique of Patent Document 1, a meal menu is created based on storage means for storing information on the nutritional value of ingredients, and this is transmitted to the hospital. The hospital adjusts the meal based on the menu information within the allowable range of the nutrition intake of the patient while taking into account the patient's wishes, and provides it to the patient.
JP 2003-141259 A

  However, in the technique described in Patent Document 1, the nutrition to be ingested by the patient is managed, but this cannot be confirmed for the amount of food intake after the patient has eaten. It was out. Therefore, even if the information on the nutritional value of ingredients is made into data, and a meal menu is created and the meal according to the menu is provided to the patient, how much the patient takes each food for the served meal, I couldn't figure out how much nutrition was consumed after eating. Therefore, in order to confirm the nutrition taken, hospital staff such as doctors, nurses, nurses, etc. are currently conducting interviews during patrols, etc., which is inefficient. It was not accurate and was inadequate for nutritional management of hospitalized patients.

  In view of the above-mentioned problems, the present invention is an improvement and removal of the above, and a hospital food intake confirmation system capable of electronically capturing how much food an inpatient has consumed in an actual meal. It is to be provided.

  Thus, the means of claim 1 adopted by the present invention in order to solve the above-described problem is to measure the weight of the tableware to which the wireless tag is attached, the tableware, and the storage unit of the wireless tag. A hospital food intake confirmation system comprising an electronic scale for reading / writing data, and a nutrition management server for inputting information from the electronic scale and managing nutrition intake for each patient .

  The electronic weighing of the means of claim 2 adopted by the present invention is the hospital food intake confirmation system according to claim 1, wherein the patient measures the weight of the food containing the food before the patient eats, By measuring the weight of the tableware after eating, the amount taken by the patient for each food is output as data to the nutrition management server.

  According to the first aspect of the present invention, the electronic weight as a reader / writer transmits and receives data by wireless radio waves to the wireless tag attached to the tableware. In other words, when empty tableware is placed on the electronic scale in the serving room, wireless radio waves are supplied from the electronic scale, and the wireless tag antenna of the tableware receives this to generate an operating power source. Then, in the storage unit of the wireless tag, the ID of the tableware itself (recognition number, weight data, etc.), the data about the patient, and the data about the food (type, amount, etc.) It is input via an input device such as a keyboard.

One tray is used for one patient's meal, and it is transported to the front of a hospital room etc. by a food distribution cart. Each patient takes out his name tag tray from the lunch box and eats in the hospital room. After the meal, the tray is returned as it is to the lunch box.
After the meal, the lunch trolley is taken to the leftover processing room. Here, using one tray as a unit (for each patient), data stored in the wireless tag of each tableware is read by electronic weighing. When each tableware is placed on the electronic scale, the ID of the patient, the ID of each tableware, and the type and amount of food stored in the tableware are read from the storage unit of the wireless tag. At the same time, the weight of the tableware is measured and the remaining amount of food served is calculated. That is, the patient's food intake is measured. This data is output to the nutrition management server.

  In this way, all nutrient intakes of food delivered to each patient are measured electronically in a contactless manner, with one tray as a unit. Data can be accurately managed without leaking the amount, and appropriate dietary therapy for the disease can be achieved.

  As described in claim 2, the electronic weighing unit can accurately determine the nutritional intake of food provided to a specific patient by simply measuring the weight of each tableware after the meal. Is unnecessary.

  The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. 1 to 5 relate to an embodiment of the present invention. FIG. 1 is a block diagram showing the entire hospital food intake confirmation system, FIG. 2 is a block circuit diagram of a wireless tag, and FIG. FIG. 4 is a schematic diagram showing an example of each meal, FIG. 4 is a diagram showing the relationship between the electronic weighing and the nutrition management server, and FIG. 5 is a flowchart.

  As shown in FIG. 1, the hospital food intake confirmation system of this embodiment includes a hospital system (medical system) 2 connected to a hospital database 1, an electronic scale 3, doctors, nurses, nurses, and the like. A terminal device 4 such as a notebook personal computer to be used and a nutrition management server 5 are connected online. As shown in FIG. 3, hospital meals are prepared for one patient on one tray 6 and arranged and served on dedicated dishes 7A to 7C. A wireless tag 14 (see FIG. 2) is attached to each tableware 7A to 7C by a sticking or embedding method.

  As shown in the block circuit diagram of FIG. 2, the wireless tag 14 receives a radio wave from the reader / writer (electronic weighing unit 3) side by an antenna 8 and generates a power supply for operation in each part. A memory circuit 10 that reads and writes data such as the patient ID, the ID of the tableware itself, and the types and amounts of foods arranged in the tableware 7A to 7C, and an asynchronous microprocessor (MPU) 11 that performs predetermined process control and arithmetic processing And a high-frequency circuit 12 for transmitting and receiving data in the memory circuit 10. The microprocessor 11 can perform data communication via the external communication port 13.

  Next, the operation | movement aspect of the hospital food intake confirmation system comprised in this way is demonstrated based on the flowchart of FIG. First, as for meal data for a specific patient, instructions from a doctor are stored in the hospital database 1 through the hospital system 2. In addition, the hospital system 2 extracts doctor instruction data regarding the meal of the patient stored in the hospital database 1, and outputs this to the nutrition management server 5. The nutrition management server 5 creates a meal menu corresponding to the doctor's instructions for each patient. The nutrition management server 5 performs nutrition management for each patient, for example, by recording the nutrition taken after meal for each patient. The managed data is accumulated in the hospital database 1 through the hospital system 2. Doctors and nurses can access the nutrition management server 5 from the terminal device 4 and check the nutrition management status of each patient.

  By the way, a person in charge such as a nutritionist who performs nutritional management of hospital food creates a meal menu for each patient based on instruction data from a doctor, and stores the data in the nutritional management server 5. And the meal menu for every patient from the nutrition management server 5 is displayed on the terminal device 4 of a kitchen. The person in charge of cooking cooks a meal for each patient based on the displayed meal menu, arranges it on each tableware 7A to 7C for each type in the preparation room, and distributes it to the tray 6 prepared for each patient. I have to.

  At the time of arrangement, first, an empty tableware 7A is placed on the electronic scale 3 and an empty weight is measured. As a result, a radio wave is transmitted from the electronic weight 3 serving as a reader / writer, and the antenna 8 of the wireless tag 14 attached to the tableware 7A receives it and causes the power regeneration circuit 9 to generate a power supply for operation. . Therefore, the wireless tag 14 is in an operating state. The electronic scale 3 as a reader / writer simultaneously transmits data on the measured weight of the tableware 7A itself. The wireless tag 14 receives this at the receiving unit of the high-frequency circuit 12 through the antenna 8, and stores the empty weight of the tableware 7 </ b> A in the storage circuit 10.

  The electronic scale 3 as a reader / writer includes data (name, sex, age, ward, hospital room, etc.) related to a patient input by an input device such as a barcode reader or a keyboard (none of which are shown), and the tableware 7A. Data on the type of food to enter is also transmitted by radio waves. These data are similarly stored in the storage circuit 10 of the wireless tag 14.

  After that, a meal is arranged on the tableware 7A. This time, the electronic weighing unit 3 transmits data relating to the weight after the arrangement to the wireless tag 14 side, and is similarly stored in the memory circuit 10. As a result, the weight of the tableware 7A after serving and the weight of the empty tableware 7A are clarified, and by subtracting this, the amount of food (shown in the drawing shows the case of rice) served on the tableware 7A can be understood. It becomes like this.

  Thereafter, the contents of meals served to one patient are similarly performed on the respective dishes 7A to 7C placed on the tray 6 prepared for each patient. In addition, the data obtained with the electronic weight 3 in this way is also transmitted to the nutrition management server 5 online and stored therein. On the other hand, a name tag of the corresponding patient is prepared in each tray 6.

  In this way, when the catering is performed on the tray 6 prepared for each patient by the dedicated tableware 7A to 7C, it is transported to the front of the hospital room or the like by the feeding car. Each patient takes out the tray 6 on which his / her name tag is displayed from the food distribution cart and eats it in the hospital room. Then, after the meal, the tray 6 is returned as it is to the lunch box.

  After the meal, the distribution car for lunch is brought back to the preparation room. Here, the data stored in the wireless tags 14 of the dishes 7 </ b> A to 7 </ b> C is read by the electronic scale 3 with one tray 6 as a unit (for each patient). Reading is only required to place each tableware 7A to 7C on the electronic scale 3. When each tableware 7A-7C is placed on the electronic weighing unit 3, the patient ID from the storage circuit 10 of the wireless tag 14, the ID of each tableware 7A-7C, the type of food stored in the tableware 7A-7C, and The quantity data is read out. At the same time, the weight of each tableware 7A-7C is measured.

Therefore, in the electronic scale 3, the patient ingests the meal by subtracting the weight of each tableware 7A-7C after the meal that has just been measured from the weight after serving read from the wireless tag 14 of each tableware 7A-7C. It is possible to accurately calculate the amount of food consumed. That is, the amount taken by the patient for each type of food can be accurately calculated. These data are output online to the nutrition management server 5 and recorded.
Therefore, the nutrition management server 5 can accurately manage the data of nutrition intake for each patient without omission, and enables appropriate dietary therapy for the disease.
