Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an infusion device such as a Ringer's injection for injecting various drug solutions in a drug solution bottle (prior art). Changes in the amount of liquid in the medicine bottle in various types of infusion devices are visually checked.

(Problems to be Solved by the Invention) By the way, in Ringer's injection, etc. in which various types of *g are infused, a considerable amount of time is required from the start to the end of the injection, and this time also depends on the patient's constitution. Since it varies depending on the condition and the amount of liquid to be injected,
Frequent supervision by a nurse or attendant was required. This places a heavy mental and physical burden on not only the patient but also the nurses and attendants.

Therefore, the present invention has been devised in view of the above circumstances.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention provides a liquid collection bottle needle to be inserted into a medicine bottle at one end of an infusion tube, and an infusion bottle needle inserted into a blood vessel at the other end. In an infusion device A to which a needle is attached and a medicinal solution collected from a medicinal solution bottle is infused, a weight detector detects the amount of decrease in the medicinal solution in the medicinal solution bottle, and when the weight value reaches a set value, The system is configured to notify the user using an alarm device such as a buzzer or flashing light.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

The drawings show one embodiment of the 'mii detection and alarm device for infusion devices according to the present invention, and the figures are schematic configuration diagrams showing the state of use;
The cross-section diagram is an enlarged front view of the weight detector. In these figures, 1 shows an example of an infusion device such as a Ringer's injection,
Reference numeral 2 denotes an @-tube, and one end of the infusion tube 2 is attached with a liquid collection bottle needle 5 to be inserted into a medicine bottle 4 via an infusion tube 3, and an injection needle 7 is attached to the other end of the infusion tube 2 via an octopus tube 6. is the installation. 8 is a flow regulator 1111 interposed in the infusion tube 2.

The lower end opening of the drug solution bottle 4 is sealed with a rubber stopper 9, and various drug solutions 10 are sealed inside. Reference numeral 11 indicates a hanging body attached to the drug liquid bottle 4, and 12 indicates a hanging body attached to the drug liquid bottle 4, which is inserted into the rubber stopper 9.
The air needle 12 is designed to slow down the inside and outside of the bottle 4.
It is inserted when infusing the liquid 10 inside.

Reference numeral 13 indicates a weight detector, and a lower end trap of the weight detector 13 is a hook 14 for hanging the medicine bottle 4 and reacting the weight thereof.
A hanging body 15 is attached to the upper end, and the detector 13 is connected to the stand 1 via this hanging body 15.
60 is configured to be suspended from a predetermined part. 17 is a pointer of the detector, and 18 is a memory.

19 is an alarm electrically connected to the detector 17 and activated by the detector 17;
9a and a flashing light 1cb. The alarm device 19 is placed at a desired location.

Here, the weight detector 13 continuously measures the weight of the liquid, that is, the liquid medicine bottle 40, which is hung on the hook 14, and the weight of the liquid 10
When the weight reaches a set value due to a decrease in weight, a command is issued to activate the alarm 19. For example, a general-purpose alarm with a contact, including a simple electric relay, is sufficient for that purpose. can be achieved. In other words, the weight detector 13 may be configured so that the set value (weight) can be changed and set as desired, and the alarm 19 continues to operate when the weight falls below the set value. .

In the figure, 20 is the wiring that connects the detection unit 13 and the alarm 19, 21 is the tube holder attached to an appropriate part of the stand 16, and the tube holder 21 is the body for the 'Ni measurement of the chestnut skin 4. This is provided to improve accuracy. Further, 22 represents a partition wall, 0 represents a hospital room, and 24 represents a nursing detention area.

The liquid volume detection and alarm device for an infusion device according to the embodiment is constructed as described above, and its usage and operation will now be explained. In the embodiment, the alarm 19 is placed on the stand 16 of the hospital room.
It is disposed at the upper end and at the wall 22 of the nursing restraint 24. Therefore, the hook 14 of the detector 13 hung on the stand 16
Hang medicine liquid bottle 4 on it. First, the operating section (not shown) of the detector 13 is operated to set the detector '13 to a set weight. This can be done, for example, as follows. That is, for example, bottle 40 weight 100&, drug solution 1
If the weight of 0 is 200y, Todoroki's weight will be 300g.

Therefore, the 11' alarm 19 is set to be activated when the weight reaches an appropriate value before the liquid 10 runs out, for example 110 g. An example of this is shown in the diagram, where the actual position of the pointer 17 points to 300g of the memory, and the position of the imaginary line of the pointer 17 points to 110.9? :pointing.

Therefore, the bottle needle 5 and the air needle 1 are attached to the rubber stopper 9.
2 and insert the injection needle 7 into the patient's blood vessel,
The current is adjusted with the accentuator B114 moderator 8 to perform infusion.

Then, the liquid level of drug solution 10 in bottle 4 is lowered (decreased).
Then, when the pointer 17 of the detector 13 reaches the position shown by the imaginary line in Fig. 12, the detector activates the alarm 19, so the buzzer 19G sounds and the flashing light flashes.
The liquid in the bottle is running low, that is, the liquid is almost finished (
Report what happened.

(Experimental Example) When the apparatus of the present invention was used on a trial basis, the following data were obtained. 300 cc +) gel (starting weight 560 g>
When the final weight was set at 290 g, the alarm activated within a range of ±5 g, and it was found that it was sufficiently usable for practical use.

(Effects of the Invention) As described above, the present invention uses a TLjIk detector to detect a decrease in the amount of medicine in the medicine am in an infusion device, and when the weight value reaches a set value, the detector sets an alarm. According to the present invention, the following effects can be obtained.

(b) Reducing the mental and physical burden on nurses and patients,
It can be streamlined.

(b) Even if the patient falls asleep during the IV pressure test, the alarm will act as a wake-up call.

(c) Intravenous pressure testing can be performed safely even in the case of visually impaired patients.
