Description

[Detailed description of the device] (Field of industrial application) This device is used to monitor the status of infusions or blood transfusions during infusion treatment or blood transfusions for patients in hospitals, etc. The present invention relates to an intravenous drip and blood transfusion status monitoring device that automatically notifies practitioners such as doctors and nurses of the completion of infusion.

(Prior Art) As is well known in the past, this type of intravenous therapy or blood transfusion in hospitals, etc. (hereinafter, to avoid complication of explanation, we will mainly discuss the case of intravenous therapy) However, it is safe to assume that the same applies to blood transfusions, and the present invention is not limited to intravenous drip therapy.) Suspend the IV fluid container in an inverted manner on an auxiliary stand placed at The patient's veins are pierced, and the patient's veins are injected with drip fluid from the drip container.

This intravenous drip treatment requires a considerable amount of time from the start to the end of the infusion, and there are many cases in which the needle remains stuck in the vein even after the remaining amount of the intravenous fluid is used up. Because it is dangerous for reasons of In other words, they may monitor the remaining level of the intravenous fluid in the intravenous container and take appropriate subsequent measures at the end of the infusion, or they may be able to do so in patients who are capable of doing so. If there is, the patient himself/herself monitors the remaining level of the intravenous fluid, and when it approaches the end, presses the push button switch on the communication alarm connected to the nurse center to notify the patient, calls the practitioner, and finishes the procedure in the same way. I am trying to get them to take the next steps.

(Problem to be solved by the invention) However, in the case of the above-mentioned infusion treatment, when the practitioner directly monitors the point at which the infusion ends, as in the former method, it is difficult to immediately carry out treatment after the end of the infusion. However, even in this case, there is not necessarily a risk of overlooking the end of the infusion, and the patient himself/herself must monitor the end of the infusion as in the latter method. In cases where the patient is unable to announce the end of the infusion, for example, if the patient falls into an emergency situation or falls asleep during infusion treatment, it is natural for the practitioner to However, there was a problem in that it was not possible to confirm the end point of the infusion, and there was a risk that the treatment following the end of the infusion would be inappropriate.

This invention was made to solve these conventional problems, and its purpose is to automatically and promptly notify the practitioner of the end of intravenous treatment, infusion during blood transfusion, or blood transfusion. It is an object of the present invention to provide a drip status monitoring device capable of reporting.

(Means for Solving the Problem) In order to achieve this objective, the infusion and blood transfusion status monitoring device according to this invention monitors the remaining amount of the intravenous fluid, the intravenous fluid in the transfusion blood container, and the transfused blood. This allows the operator to be reliably informed of the end point of infusion or blood transfusion.

That is, this device is an infusion and blood transfusion status monitoring device for performing intravenous therapy and blood transfusion on a patient, who is the subject of the treatment, and is designed to monitor the intravenous fluid and blood transfusion container suspended in an inverted position. In addition to disposing a remaining amount detection means for detecting the remaining amount of intravenous fluid and transfused blood, the doctor, nurse, etc. In an intravenous drip and blood transfusion status monitoring device configured by arranging a remaining amount reporting means for reporting the amount, the remaining amount detecting means detects the respective liquid volume levels of the intravenous fluid and transfused blood in the safety zone, caution zone, and danger zone. A combination of a light-emitting element and a light-receiving element corresponding to each zone is used to detect the range.
This is a drip and blood transfusion status monitoring device that is equipped with a light emitting means that electrically connects each detection output in a caution zone and a danger zone to a light receiving element corresponding to each zone, and emits light in a different color corresponding to each zone.

(Function) Therefore, in this invention, when administering intravenous treatment or blood transfusion to a patient who is undergoing treatment, the remaining amount of intravenous fluid or transfused blood in the container body is detected by the remaining amount detection means, and the remaining amount of transfused blood is detected in this way. The remaining amount of intravenous fluid or transfused blood detected by the operator is notified to the practitioner (doctor, nurse, etc.) by the remaining amount notification means, so that the practitioner can grasp the point at which the infusion or blood transfusion is completed, and the remaining amount of the transfused blood. , or appropriate follow-up measures may be taken upon completion of blood transfusion.

In addition, as a residual amount detection means, a light-emitting element and a light-receiving element corresponding to each zone are used to detect each liquid volume level range of intravenous fluid or transfused blood in the safety zone, caution zone, and danger zone. In addition, when using a means to notify each detection output in each zone by coloring as the remaining amount notification means, in addition to simplifying the structure of the means itself, the treatment This makes it possible to more accurately monitor the state of the infusion or blood transfusion on the patient's side, and to know when the infusion or blood transfusion has ended.

(Example) Hereinafter, with reference to the drawings, the infusion according to this invention,
An example of a blood transfusion status monitoring device will be described. It should be noted that the drawings are merely shown schematically to the extent that this invention can be understood, and therefore, the relationships such as dimensions, shapes, and arrangement of each component of the device are not necessarily limited to the illustrated examples. do not have. In addition, in this embodiment, as in the above, the case of intravenous drip treatment will be mainly described, but it is safe to assume that the case of blood transfusion is almost the same, and the present invention is applicable to other cases of blood transfusion as well. However, it is not limited to intravenous treatment. Note that although a means for notifying by sound is outside the scope of this invention, a sound notifying means may also be incorporated, so in the following description, an example including a light emitting means and a sounding means will be explained.

FIG. 1 is a system configuration diagram schematically showing the outline of the infusion and blood transfusion status monitoring device according to this embodiment, and FIG. FIG. 3 is a cross-sectional view of the main part showing an enlarged view of the remaining amount level detection section, and is a conceptual diagram illustrating the remaining amount level detection means of the same intravenous fluid and transfusion blood,
Furthermore, FIG. 4 is a conceptual diagram illustrating a means for detecting the remaining amount of intravenous fluid and transfused blood according to another embodiment.

First, in the system configuration shown in Figure 1, A indicates a hospital room, B indicates a nurse center where a practitioner such as a nurse waits, _a1 indicates a patient lying on a hospital bed in hospital room A, and _a2 indicates an IV drip. It is an auxiliary stand for treatment.

In the hospital room A, the intravenous liquid container 11 containing the intravenous liquid is placed in the container body ₁₂ , for example, with respect to the hook of the auxiliary stand a2 for intravenous treatment, as is well known in the art. It is suspended in an inverted manner using an attached hanger 13, and the supply capillary 14 including the trap part 15 is taken out from the closed container mouth of the inverted intravenous liquid container 11 through the lid, and also suspended. After adjusting the height position of the trap part 15 to be lowered as expected, the injection needle 1 connected to the end of this supply tube 14 is inserted.
6 is inserted into the vein of the patient _A1 , and the intravenous liquid dripped from the intravenous liquid container 11 at predetermined unit time intervals and unit amounts is temporarily stored in the trap part 15. The intravenous fluid stored in the trap portion 15 is allowed to flow down by gravity in appropriate amounts to be infused into the vein of the patient _a1 .

Further, as shown in FIGS. 2 and 3, the intravenous fluid remaining amount detection means according to this embodiment is located on the outer periphery of the container body 12 of the intravenous fluid container 11 on the side of the hospital room A. and the required holder 24
By using this, liquid level detection sensor units 21G, 21Y and 21R are installed for each predetermined liquid level, and on the nurse center B side,
It is constructed by arranging an intravenous drip notification section 31 as a remaining amount notification means corresponding to each hospital room A.

That is, each liquid level detection sensor section 21G, 21Y, 21R on the side of hospital room A has 1
It has a set of light emitting elements 22g, 22y, 22r and light receiving elements 23g, 23y, 23r. Zone (which also means starting an infusion and being in an infusion) applicable fluid level range G
Be careful when the remaining liquid volume is about to run out (when the remaining time for drip supply is sufficient to take subsequent measures, for example, about 5 minutes). The liquid level corresponding to the (yellow) zone is detected by the detection sensor unit 21Y located above the range Y of the liquid level corresponding to the dangerous (red) zone where the remaining liquid level is almost gone and it is necessary to take immediate action. Detection sensor sections 21R are arranged below the liquid level range Y approaching the range R, and each of these light emitting elements 2 is arranged for each liquid level range G, Y, R.
2g, 22y, and 22r emit directional light from the respective light receiving elements 23 facing each other through the intravenous liquid container 11 only when the liquid level of the intravenous liquid drops below the corresponding level.
g, 23y, and 23r can detect light reception. Additionally, this embodiment is applicable to cases where the intravenous liquid itself is opaque to light or has low light-transmissive properties.

On the other hand, the drip notification unit 31 for each corresponding patient room A on the nurse center B side includes each liquid level detected by the light emitting elements 22g, 22y, 22r and the light receiving elements 23g, 23y, 23r of each set. A controller 32 that controls the output for each range G, Y, and R, and indicator lights that make different displays for each corresponding level depending on the notification output from this controller 32, that is, a blue light 34G and a yellow light in this case. Similarly, this controller 32 includes a lighting indicator 33 that selectively turns on either the light 34Y or the red light 34R.
The sound generating buzzer 35 generates a different display sound for each corresponding level according to the notification output from the sound generating buzzer 35.

For example, each of these lighting indicators 33,
And for the sound buzzer 35, the drip liquid container 1
Depending on the amount of remaining intravenous fluid in the container, the following classifications are used:

If the liquid level is higher than the safe (green) zone corresponding liquid level range G. When the power is turned on at the start of the infusion, the light emitting element 22
The emitted light from g is blocked by the intravenous fluid and reaches the light receiving element 23.
Although no light is received by the blue light 34G, the blue light 34G is turned on in this state. At the same time, if necessary, a sound buzzer 35
It plays a pleasant low-pitched sound. Further, when the level of the intravenous fluid gradually decreases and the emitted light from the light emitting element 22g is received by the light receiving element 23g, the blue light 34
G starts blinking to indicate that you are approaching the caution (yellow) zone.

When the liquid level falls within the range Y corresponding to the caution (yellow) zone. When the level of the drip liquid exceeds the liquid volume level range Y and reaches the level between the light emitting element 22y and the light receiving element 23y, the emitted light from the light emitting element 22y is received by the light receiving element 23y, causing the blue light 34G to blink. At the same time, the yellow light 34Y is turned on to display in color that the current remaining amount of intravenous fluid is within the fluid level range Y, and at the same time, a sounding buzzer 35 emits a medium-low tone warning sound.

Liquid level range R corresponding to the danger zone
If it reaches . When the level of the drip liquid approaches the liquid volume level range R and reaches the level between the light emitting element 22r and the light receiving element 23r, the emitted light from the light emitting element 22r is received by the light receiving element 23r, and the yellow light 34Y is turned on. At the same time, the red light 34R is turned on.
Alternatively, by blinking to indicate that the remaining amount of intravenous fluid has reached the liquid level range R, and at the same time, the sound buzzer 35 emits a high-pitched intermittent warning sound, indicating that the infusion is about to end and that It alerts you to the need for action.

Note that the above-mentioned use of each of the lighting indicators 33 and the sounding buzzer 35 is not necessarily limited to this example, and it goes without saying that any combination of display and sounding may be set.

Next, a modified example of the combination arrangement of the liquid level detecting means, particularly the light emitting element and the light receiving element, will be described with reference to FIG.

This modification of FIG. 4 differs from the embodiments in FIGS. 2 and 3 in that it has a configuration in which a light-emitting element and a light-receiving element are combined and arranged to take advantage of the light-opacity or light-resistance of the intravenous fluid. In contrast, this device has a configuration in which a light-emitting element and a light-receiving element are combined and arranged using liquid surface reflection of the intravenous liquid.

That is, in the case of the modification shown in FIG. 4, by disposing the common light emitting element 25 above one side of the intravenous liquid container 11, the emitted light is transmitted into the container body 12 from diagonally above one side to the other side. The liquid level surface Y _-rev corresponding to the caution (yellow) zone and the danger (red) are projected diagonally downward on the side of
The light-receiving element 2 is located at the corresponding position where it can receive each specular reflection at the liquid level surface R _-rev corresponding to the zone.
5y and 25r are arranged separately.

Therefore, in the case of this modified example configuration, the detection output from the light receiving element 25y can be obtained when the liquid level of the intravenous liquid drops to the liquid level level Y _-rev corresponding to the caution (yellow) zone. , and similarly, the fluid level surface corresponding to the danger zone.
The detection output from the light-receiving element 25r is obtained when the value has decreased to R _-rev , and the same functions and effects as in the previous example can be achieved in each case.

(Effects of the invention) As detailed above, according to this invention, in an intravenous drip or blood transfusion status monitoring device for administering intravenous drip or blood transfusion treatment to a patient, who is the subject of treatment, an intravenous fluid suspended in an inverted manner, A remaining amount detection means for detecting the remaining amount of intravenous fluid and transfusion blood in the container body is placed on the blood transfusion container, and the system is activated by the detection output from the remaining amount detection means on the side of the practitioner, such as a doctor or nurse. Since the remaining amount notification means is arranged to notify the remaining amount of intravenous fluid or transfused blood, the remaining amount detecting means detects the remaining amount of intravenous fluid or blood in the container during intravenous treatment or blood transfusion to a patient.
In addition to being able to detect the remaining amount of transfused blood, the remaining amount reporting means can also notify the practitioner of the detected intravenous fluid and remaining amount of transfused blood.As a result, the practitioner can This has the advantage that the point at which the infusion or blood transfusion ends can be quickly and reliably determined, and subsequent measures can be taken appropriately following the end of the infusion or blood transfusion.

In addition, as the remaining amount detection means, a combination of a light emitting element and a light receiving element corresponding to each zone is used to detect the level range of intravenous fluid and transfusion blood in the safety zone, caution zone, and danger zone. As the notification means, we use a means to notify each detection output in each zone by different colors corresponding to each zone, so in addition to simplifying the structure of the means itself, it is easier for the practitioner to perform intravenous drips and blood transfusions. Effective monitoring of the condition and understanding of the end point of infusion and blood transfusion can be carried out more reliably and quickly than in the case of conventional one-color display or surface graphic display, and it is also relatively simple and easy to use in terms of structure. It has excellent features such as being able to be implemented in a number of ways.
