Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a respiratory monitoring device for monitoring the respiratory condition of a patient, and is particularly characterized in that a plurality of types of respiratory flow rate transducers are connected and used. .

[Technical background of the invention and its problems]

A patient monitoring device that continuously collects various data from a patient, stores it, displays it, and gives an alarm when appropriate, especially data related to respiratory metabolism (respiratory volume, respiratory rate, carbon dioxide output, oxygen intake, etc.) A device that handles this is called a respiratory monitoring device. Sensors such as a respiratory flow transducer, a pressure transducer, and a gas analysis transducer are connected to the respiratory monitoring device to collect data such as the flow rate, pressure, oxygen concentration, carbon dioxide concentration, etc. of the gas that the patient breathes. measurements are taken.

Respiratory flow rate transducers used to measure respiratory flow rate include differential pressure type, impeller type, ultrasonic type, etc., and the flow rate measurement range, sensitivity, etc. of all types differ depending on their shape and size. If the patient's respiratory rate is small, it is necessary to use a transducer with a sufficiently small dead space. That is, an adult whose respiratory volume is several hundred ml per breath, and an adult whose respiratory volume is several hundred ml per breath.
In children under m1, different size transducers,
- It is necessary to use a server.

FIG. 3 shows a conventional respiratory monitoring device, which includes a respiratory flow rate transducer 100 and a patient monitoring device 200 connected to the respiratory flow rate transducer 100 to perform respiratory monitoring. Note that the pressure measurement and gas analysis measurement parts are omitted. The connector 3 of the transducer 100 has connection terminals 31a...31C for signals necessary for measuring drive signals, received signals, etc. of the transducer 100.
is provided. The patient monitoring device 200 has a connector 4 connected correspondingly to the connector 3, and signals are converted into digital data by an interface 6, and are subjected to calculation, storage, display, etc. via a processing/control circuit 7.

There are different types of transducer 100, such as those for adults and children, so each time you change the type of transducer 100, the measurement constants such as measurement sensitivity and the coefficients of the display scale etc. must be changed and adjusted. In order to do this, it was necessary to manually operate the operation keys 11 such as switches provided on the device 200. However, this operation is complicated, and in medical settings where emergency treatment is often required, a device that requires nurses to be familiar with complicated operations is not appropriate.
There was a serious drawback in that the operator had to forget the operations associated with changing the type of transducer.

[Purpose of the invention]

This invention improves the drawbacks of the conventional device, and when replacing a different type of respiratory flow rate transducer, each coefficient such as sensitivity can be changed without manual operation.
The purpose is to do this automatically.

[Summary of the invention]

This invention connects or disconnects specific terminals of a connector on the transducer side of a connector that connects a respiratory flow rate transducer and a patient monitoring device main body, depending on the type of transducer. On the other hand, the main unit of the device determines whether this specific terminal is connected or disconnected, and changes each coefficient etc. by selecting a processing routine based on the determination result. The aim is to automatically replace transducers.

〔Effect of the invention〕

According to this invention, when changing the type of respiratory flow rate transducer, it is possible to automatically change each coefficient such as sensitivity. Therefore, different types of respiratory flow rate transducers can be exchanged with the minimum operation of connecting the connector, eliminating the need for complicated operations. It also prevents operational errors when replacing transducers, thereby eliminating the possibility of collecting erroneous data. Furthermore, since it becomes possible to determine and display the type of lance transducer, there is an advantage that it also helps to prevent mistakes in connecting transducers.

The connection terminals 32 and 33 of the connector 3 are the parts that distinguish the types of transducers according to the present invention, and FIG. 1 shows the connection 35.

In this embodiment, the connecting terminals 32 and 33 are connected or disconnected by shorting or opening the connecting terminals.

The connector 4 of the patient monitoring device 201 has a connection terminal 42.
, 4.3, and by connecting the connector 3, the terminals 4.2 and 43 are connected. This state is determined by the determination circuit 5, and a low level is outputted to its output 25, thereby determining and displaying that the pediatric transducer is connected. Furthermore, this output 25 is input to the processing/control circuit 7, and a processing routine for the pediatric transducer 101 stored in the ROM of the storage circuit 9 is selected and executed, thereby processing and storing the data. A display etc. is made.

FIG. 2 shows the case where the sensor is for adults. Since the terminals 32 and 33 of the connector 3 are disconnected 36, when the adult transducer 102 is connected to the patient monitoring device 201, the output 25 of the discrimination circuit 5 becomes High, and the processing for the adult transducer 102 is performed. Routines are selected to process, store, and display data.
