Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is used in infusion devices such as Ringer's injections for drip pressure testing of various drug solutions in drug bottles. The present invention relates to a liquid level detection alarm device for an infusion device that detects a change and automatically notifies the user with an alarm.

(Prior Art) Conventionally, changes in the liquid level of the medicinal solution in the medicinal solution bottle in the infusion device for mosquitoes have been visually observed.

(Problems to be Solved by the Invention) By the way, C, which is suitable for Ringer's injection, etc., in which a % type of drug solution is injected, takes a considerable amount of time from the start to the end of the injection (1 o'clock to 6 o'clock).
During the IV pressure test, a nurse or an attendant should frequently monitor the patient's condition and the amount of fluid to be injected. I needed to.

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 that is inserted into one end of the infusion tube and into the medicine liquid bottle through the drip tube.
An infusion needle is attached to the other end that is inserted into the blood vessel, and a sensor detects the liquid level of the medicinal solution in the medicinal solution bottle or in the drip tube in an infusion device that imitates the dot injection of liquid taken from a medicinal solution bottle. However, when the liquid level reaches a predetermined level, a notification is given by a buzzer, a blinking light, or the like.

(Operation) The above technical means operates as follows. When the liquid level of the medicinal solution in the medicinal solution bottle gradually decreases and reaches a predetermined value tK, the sensor detects this, and the detection output activates an emergency alarm such as a buzzer or flashing light, and the medicinal solution level is lowered. Notifies that the liquid level has reached a predetermined position.

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

, 1-/ shows an embodiment of the liquid level detection and alarm device for an infusion device according to the present invention, FIG. 7 is a schematic configuration diagram, and FIG. 2 is an explanatory diagram showing the state of use. In these figures, 1 shows an example of an infusion device such as a Ringer's injection, 2 is an infusion tube, and at one end of the infusion tube 2 is a liquid collection bottle needle 5 that is inserted into a medicine bottle 4 through an infusion tube 3. At the same time, a press-fitting needle 7 is attached to the other end via an octopus tube 6. Reference numeral 8 denotes a flow rate regulator interposed in the tube 2.

The lower end of the medicine bottle 4 is sealed with a rubber stopper 9, and there are 6
A plant medicinal solution 10 is enclosed. Reference numeral 11 denotes a hanging body attached to the drug liquid bottle 4 in an i-layer, and 12 inserts it into the rubber stopper 9 to hang the drug liquid bottle 4.
The air needle 12 is for slowing the inside and outside of the bottle 4.
It is inserted when infusing the liquid 10 inside.

Reference numeral 13 denotes a sensor for detecting the liquid level, and the base end of an optical fiber 14 is connected to the input side of the sensor, and a suction cup 15 is attached to the tip of the optical fiber 14. 16 is an alarm electrically connected to the sensor 13 and activated by the sensor 13; The alarm device 16 of the embodiment includes a buzzer 1≠ and a flashing light 16b. The sensor 13 and newsletter device 16 are arranged at desired locations.

Here, the sensor 13 is located inside the medicine bottle 4 (or the drip tube 5).
The device detects changes in the liquid level of the chemical solution 10 (inside) using light, and when the liquid level reaches a predetermined position, issues a command to activate the bulletin device 16. Any number of sensors can be employed.

In the figure, 17 is a wire connecting the sensor 13 and the alarm 1b, 18 is a stand from which the medicine bottle 4 is suspended,
Further, 19 indicates a partition wall, 20 indicates a hospital room, and 21 indicates a nursing starting room.

The liquid level detection and alarm device of this embodiment is constructed as described above, and its usage and operation will be explained next. In the embodiment, as shown in the diagram, a sensor 13 is disposed at the upper end of a stand 18, and an alarm 16 is disposed at the upper end of the stand 18 of the hospital room 20 and the wall 19 of the nursing starting room 21. A suction cup 15 attached to the tip of the optical fiber 14 of the sensor 13 is attached to the outer circumferential surface of the medicine bottle 4 or the outer circumferential surface of the drip barrel 3. First of all, medicine bottle 4
When suctioning the suction cup 15 to the outer peripheral surface of the liquid medicine bottle 4, the suction cup 15 is placed near the bottom of the liquid medicine bottle 4 (i.e., a position corresponding to the lowering position near the end of the liquid medicine 10 in the liquid medicine bottle 4, for example, 1.?/point m in the figure).
Adsorb it to match the position indicated by 1 oa.

Therefore, as before, the bottle needle 5 and air needle 12 are attached to the rubber stopper.
At the same time, the injection needle 7 is inserted into the patient's blood vessel, and the flow rate is adjusted with the flow rate regulator 8 to perform drip infusion.
By dripping, the Kurifu 10 in the medicine bottle 4 is lowered from the bottle needle 5 into the drip tube 3, and is stored in the drip tube 3 to a predetermined height.
The infusion is injected from the infusion tube 2 through the octopus 16 and the injection needle 7 into the patient.

And the karma inside medicine bottle 4? [[As lO decreases, the liquid level drops to the next level, and the liquid level of the chemical solution 10 reaches the set position of the optical fiber 14, that is, point t in Figure 1,177! 1
When the position ≠ is reached, the sensor 13 detects this via the optical fiber 14, and the detection output activates the alarm 16, so the buzzer 1- sounds and the blinking light 16b blinks, indicating that the liquid in the bottle 4 Reports that there are few remaining, that is, the end is near.

In addition, when the suction cup 15 is attached to the outer circumferential surface of the drip tube 3, a position corresponding to the lowering position near the bottom of the drip tube 3, near the end of the stored drug solution 10 in the drip tube 3, for example, 3
-7 The suction cup 15 is sucked as shown by the chain line in FIG. 7, matching the position shown by the dot 110b. In this case, the change in the liquid level of the drug solution 10 in the drip tube 3 is detected, and the liquid level of the drug solution 10 in the drip tube 3 drops to the next point.
When the position of point 10b in Fig. 7 is reached, this is connected to the optical fiber 1.
4, the sensor 13 detects the
6 to notify that the liquid in the drip tube is running low.

(Effects of the Invention) As described above, the present invention uses a senna to detect the liquid level of a drug solution in a drug bottle or an intravenous drip tube in an infusion device, and when the upper liquid level reaches a predetermined position, the sensor Since the present invention is configured to activate the alarm and notify the user, the present invention has the following effects.

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

(b) Even if the patient falls asleep during the IV drip, 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.
