Description

[Detailed Description of the Invention] When feeding nutrients, drugs, blood, etc. into the human body's blood vessels for medical purposes, if the end of the drip is not correctly detected, the blood may flow back into the drip vibrator or the drip speed may be too fast. This may place an excessive burden on the heart and have a negative impact on the patient.

However, with the current IV drip method, this monitoring is not left entirely to the nurse, an attendant, or the polisher himself, but is carried out by notifying the nurse's office by ringing a bell when necessary.

The present invention automatically detects the rate or end of the infusion and issues an alarm or communicates it to the nurse's office by wire or wirelessly, and its outline is shown in FIG. Intravenous fluid 1
is placed in the container 2 and flows down the vibrator 3 into the drip section 4. Vibro, flowing fat tl1 node 7° through injection needle 9 to arm 10
or injected into appropriate blood vessels in the body. There is a monitoring device 5 in the drip section, and an example of its structure is shown in FIG.

In Figure 2 (the light emitted from the light source 11 is
2 and enters the light receiving device 13 installed on the opposite side of the dripping section 4. When the intravenous drip 18 breaks the optical path, the electronic circuit section 16 equipped with the power source 14 and the detection and counting 1 transmitter counts the number N of intravenous drips per unit time. An alarm is issued using a lamp, buzzer, etc., or sent to a nurse's station, etc.6 by wire or wireless.
Please contact me.

At this time, if the antenna 17 is allowed to hang down, the transmission capability can be increased.

Patent applicant Asahiko Seiko Ha (Tachibatake-3 Higashi) Setting values A and B can be arbitrarily adjusted by rotating the scale shaft 15.The flow rate itself can be adjusted by moving the rotary wheel 8 of the flow rate adjustment section 7. Although it can be adjusted, the rotating ring 8 may loosen naturally during use or may rotate due to patient movement.Then, the number of drops per unit time N is
An alarm will be issued if it shifts above or below between -B. If the intravenous fluid runs out, it becomes N,,=0, which naturally shifts downwards from the A-B line, so an alarm will be issued.Figure 2 shows the case of a transmission type optical path, but the fear is shown in Figure 3. There is no problem even if it is a reflective type. In this case, the light emitted from the light source 11 hits the drip, and the reflected light enters the light receiving device 13, and the number of flickers caused by the passage of the drip is counted.

FIG. 4 shows an example in which natural light in the room is used without installing a specific light source, and changes in the amount of light received due to dripping are used. In this case, if an ID shield 21 is provided on the container wall in front of the light receiving device 13 and a window 22 is opened in a part of the ID shield 21, the flickering effect of the drip can be ensured.

Patent Applicant: Asahiko Seiko Kawa 4-Jm When a battery or the like is used as the N source, there are cases where the battery is exhausted and no alarm is issued even if an abnormality occurs in the number of infusions N. In order to prevent this, for example, as shown in FIG.
It is also possible to consider turning on 5. It is equally possible to use the main lightning to perform the above action without forcing the installation of a second power source.

In order to avoid troubles caused by exhaustion of the air source, the KiJ force may be guided from the outside by an electric wire 32 as shown in FIG. In this case, using this electric power, the auto controller 31 is placed in parallel to the flow 111M node 7, and when an abnormality occurs in the number of drips NK, the rotary wheel shown in FIG.
It is also conceivable to automatically adjust the temperature to return to between -B and 6.

Patent applicant: Asahiko Seiko Co., Ltd. -? It is also conceivable that the rain warning could be transmitted by wire instead of wirelessly, as shown in Figure 6, 33, and by using the bell circuit currently used by patients to call the nurse's office. In any case, the latest 10. By using the L3I, the detection and counting 1 transmitter can be made very small, and if a mercury battery is used as the power source, it can be made lighter, and even if it is installed next to the infusion unit 4, it will not be bulky. \Maybe you won't become a sect.

The above is a case where light is used for detection, but this may also be performed electrically. That is, FIG. 7 shows a cross section of the drip section 4, and the electrical resistance of the circuit 43 changes when the drip drips through both electrodes. You may also take advantage of the fact that If it is contraindicated for the intravenous fluid to come into direct contact with the tilr, place two sheets of paper &44. on the outside of the IV passageway 4. as shown in Figure 8. 45, the change in movable capacity when the drip passes through may be used as a signal.

Patent Applicant: Asahiko Seiko User's Guide 14 The present invention detects drips optically or electrically as described above, and issues an alarm or alarm when the number of drips per unit time deviates from a set value range. This invention relates to a medical infusion monitoring device that sends signals wirelessly or automatically adjusts the flow rate, thereby reducing the burden on nurses, attendants, or polishers themselves of constantly having to pay attention to the infusion, and
It is possible to eliminate the need for excessive infusion without adversely affecting the patient's heart. If the procedure to end the intravenous drip is delayed, blood will flow back into the intravenous tube and the patient's important blood will be lost. In addition, a percentage report is automatically issued before the end of the point source, making it easier for busy nurses to organize their work.
