Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telemeter-type patient monitoring device comprising a transmitter and a receiving device for displaying, recording, etc.

[Conventional technology]

Telemeter-type patient monitoring devices, which are currently widely used, consist of a transmitter that measures biological phenomena, modulates and transmits signals, and a receiver that receives and displays or records the transmitted signals. . An example is shown in Figure 2. As shown in the figure, in conventional devices, signal waveforms and measured values are displayed and recorded only on the display and recording section on the receiving side, and the transmitter is solely responsible for amplifying and modulating the signal. is being carried out.

[Problem that the invention attempts to solve]

The main places where patient monitoring devices such as those described above are used are ICUs (intensive monitoring units), operating rooms, and hospital rooms.
On the other hand, the flow of patients within a hospital is from the operating room to the ICU or hospital room for general patients, and from the operating room to the ICU or hospital room for emergency patients after receiving emergency treatment. Some patients may require monitoring while moving from place to place. In such cases, a small portable monitor may be used when moving, but the time required for moving is not very long, and it is only a short time, and changing the connection to a small monitor is cumbersome, so monitoring is not necessary. However, the current situation is that small monitors are not used. To give one example of the cause, if the transducer model and connection pin arrangement are not the same, it is necessary to replace the entire transducer.Especially when considering replacing the blood pressure transducer, it is difficult to Flushing, zero balancing, mechanical re-fixing of the transducer, etc. must be performed, which is extremely troublesome. Furthermore, even if the connectors are manufactured by the same manufacturer, they may not be compatible unless they were manufactured at the same time. or foreign products, there is almost certainly no compatibility.

[Means for solving problems]

The present invention solves the above-mentioned problems by incorporating means for displaying a signal waveform or a measured value into a transmitter.

[Effect]

According to the present invention, the signal waveform and measured values are displayed on the transmitter itself, so there is no need to use a small monitor.

〔Example〕

FIG. 1 is an external view showing a preferred embodiment of the present invention. In the figure, 1 is a transmitter, and 2 is a transducer for detecting biological phenomena, that is, biological signal waveforms or measured values such as blood pressure, electrocardiogram, and body temperature, for example, blood pressure values obtained by an invasive blood pressure measurement method as measured values. The electrodes 1a are display devices made of liquid crystal that display biosignal waveforms or measured values using the biophenomena input from the transducer electrodes 2 as electrical signals. Although not shown, a battery is built into the transmitter 1 as a power source for display, transmission, and the like.

Reference numeral 3 denotes a receiving device, which is composed of a display section 4 such as a CRT, and a recording section 5. 4a is the receiving device 3
This is an antenna installed in the transmitter 1, and receives the radio waves transmitted from the transmitter 1.

Next, the operation of the embodiment of the present invention shown in FIG. 1 will be explained.

The transducer electrodes 2 detect biological phenomena such as electrocardiogram, body temperature, and other biological signal waveforms or measured values, for example, the measured values include blood pressure values obtained by an invasive blood pressure measurement method, and input them to the transmitter 1; It is converted into an electrical signal (biosignal) and displayed on the display 1a as a biosignal waveform or a measured value. At the same time, these biological signals are transmitted from an antenna (not shown) using radio waves.

The receiving device 3 receives the biosignal transmitted from the transmitter 1 with an antenna 4a, displays it on the display section 4 as a biosignal waveform or measured value, and also displays the desired biosignal waveform or measured value on the recording paper of the recording section 5. Record and save measurements.

Here, the above-mentioned invasive blood pressure measurement method will be explained.

Unlike non-invasive blood pressure measurement, which involves wrapping a cuff around the arm, invasive blood pressure measurement involves piercing a blood vessel with a needle and connecting it to a transducer with physiological saline to measure blood pressure. In the operating room and emergency room, patients are given intravenous fluids and various medications, and blood is drawn regularly and frequently for blood oxygen levels and blood analysis. For this reason, it can be performed using a three-way stopcock in the invasive blood pressure measurement path, and has a significance other than just blood pressure measurement in medical care. Furthermore, in invasive blood pressure measurement, an instantaneous blood pressure waveform can be obtained, and the instantaneous value of the systolic and diastolic blood pressure can also be measured. In the case of patient monitoring, biological signals include electrocardiogram waveforms, body temperature,
Respiration, blood oxygen concentration, etc. are also measured at the same time as necessary.

[Effect of idea]

The transmitters of conventional telemeter-type patient monitoring devices did not have any display function, so it was necessary to look at the display on the receiving side to know the biological data. Since biometric data can be viewed even when the patient is moving, the patient can be monitored even when the patient is away from the reception display. It is especially effective when moving from the operating room to a hospital room or ICU (intensive monitoring unit). In operating rooms, hospital rooms, and ICUs located at both ends of the movement, the functions of patient monitoring devices such as measurement, display, trend graphs, alarm generation, and recording of biological multi-phenomenal signals are required to the maximum extent. If an attempt is made to use a small portable monitor, the above-mentioned problems will occur, and moreover, the connection of transducers, etc. will have to be changed twice in a relatively short period of time. Therefore, according to the present invention, this need is eliminated, and its utility value is very large.
