Abstract

(57) [Summary] [Purpose] To provide an infusion device that can completely use up the drug solution 1 in the drug solution bottle 2 without making the patient feel anxious. [Structure] The infusion device drips the medicinal solution 1 from the medicinal solution bottle 2 into the infusion tube 4 and sends out the medicinal solution 1 from the infusion tube 4. A floating stopper 6 is provided to close the outlet 4a of the chemical solution 1 when the level falls below a predetermined level.

Description

[Detailed explanation of the idea]

For explanation, it is defined as follows. An infusion device is a device that is made up of a combination of various devices needed for infusion. A device that maintains the liquid level by dropping the drug inside the device is called a dropper. Intravenous drips play an important role in medical care and are widely used. However, with the currently used infusion device, when the drug (7) in the container (6) is empty, The liquid level (3) of the agent rapidly descends in the narrow tube (9). The person receiving the intravenous drip (referred to as the patient) is aware that the liquid level (3) is rapidly falling inside the tube (9). I have great anxiety about the condition that is falling. For this reason, the patient may be left with the drug (7) in the container (6). Call a nurse as soon as possible and ask for action. Patients become anxious when nurses arrive late. I wait, feeling nervous and irritated. When the nurse comes early, if there is any medicine (7) left in the container (6), wait until it is empty. You will have to wait, and if you are busy, you may end up replacing it with the next container even if there is some medicine left. There is also. The embodiment in the description is an example in which a dropper (1) is equipped with a floating stopper (2). The drug (7) is dripped from the drip opening (4) through the tube (8), and the medicine (7) is dropped into the dropper (1). While the liquid level (3) of the drug is maintained, the float stopper (2) floats to the outlet (5) of the dropper. ), so the drip is maintained. When the drug (7) in the container (6) is empty and stops dripping from the drip opening (4), the liquid level ( 3) descends. At this time, the floating plug (2) closes the outlet (5) of the dropper and the tube (9) closes the outlet (5) of the dropper. ) to prevent the liquid level from dropping. This way, the patient does not have any anxiety, and after the drug in the container is completely emptied, You can contact the nurse at any time. Even busy nurses can have more free time. Furthermore, valuable and expensive drugs can be effectively utilized in medical treatment without waste.

0001

[Industrial application field]

The present invention relates to an infusion device used in the medical field.

0002

[Conventional technology]

An infusion device connects a drug bottle and a drip tube with a tube, and transfers the drug from the drug bottle into the drip tube. The drug solution in the drip tube is injected into the patient's body through a tube. It is.

0003

[Problem that the idea aims to solve]

In conventional IV drip devices, when the medicine bottle is empty, the medicine in the IV tube rapidly flows through the tube. descend. When the patient saw this, he became extremely anxious and hurriedly called for a nurse. This puts the patient in an undesirable situation, such as waiting impatiently for the nurse to come. fall into In addition, patients who have had such an experience may seek help from a nurse while there is still some drug remaining. The nurse has to wait until the medicine bottle is empty. Additionally, if the nurse does not have the time to wait until the vial is empty, Even if there is some medicine left in the bottle, it may be replaced with the next medicine bottle, resulting in wasted expensive medicine. It had been abandoned.

0004

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a solution to the above-mentioned drip barrel or medicine bottle that is suspended in the medicine solution. and a float that blocks the outlet when the chemical solution drops below a predetermined level. This invention provides an infusion device provided with a stopper.

[0005]

[Effect] When there is a medicine in the medicine bottle, the floating stopper is floating in the drip tube or medicine in the medicine bottle. . Then, as time passes and the level of the chemical solution decreases, the floats floating in the chemical solution drop. The stopper also descends together, and when the drug solution runs out, it closes the outflow port of the drip tube or drug solution bottle.

[0006]

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In addition, Figure 1 shows the intravenous drip device. FIG. 2 is a perspective view, and FIG. 2 is a longitudinal sectional view of the main part. The infusion device includes a drug solution bottle 2 that supplies a drug solution 1, and a tube connected to an outlet 2a of the drug solution bottle 2. A drip tube 4 connected via a tube 3 and a tube connected to an outlet 4a of the drip tube 4. It is roughly composed of 5. As shown in FIG. 2, the tip of the tube 3 is inserted into the drip tube 4. The drug solution 1 drips from the tip of the tube 3. The bottom of the drip tube 4 has a bowl-shaped depression. The outflow port 4a is open, and the chemical solution 1 flows into the tube 5 through this outflow port 4a. Get out. A spherical floating stopper 6 is placed inside the drip tube 4. This floating plug 6 floats on the chemical solution 1, and its spherical outer peripheral surface fits into the outlet 4a to prevent the flow of the chemical solution 1. It's supposed to stop coming out.

[0007] Next, the use of the drip device will be explained. When the drug solution bottle 2 is filled with the drug solution 1 as shown in Fig. 1, the drug solution in the drip tube 4 is The level is almost constant, and as shown in FIG. 2, the floating stopper 6 is floating on the chemical solution 1. Then, as time passes and the drug solution bottle 2 becomes empty, the drug solution 1 is supplied to the drip tube 4. Therefore, the level of the drug solution in the drip tube 4 also decreases. The floating plug 6 floats on the chemical solution 1. As the chemical solution 1 decreases, it descends and finally fits into the recess of the outlet 4a. If the chemical solution 1 attempts to flow out further in this state, the floating stopper 6 will be sucked into the outflow port 4a. Therefore, the outflow of the chemical solution 1 will be stopped from then on. Although the embodiment in which the floating stopper 6 is provided on the drip tube 4 has been described above, Even if the plug 6 is provided, the effect is the same.

[0008]

[Effect of the idea]

In the drip device of the present invention, when the drug solution 1 in the drug solution bottle 2 runs out, the floating stopper 6 moves to the outlet 4a. This provides a sense of security to the patient since the outflow of the drug solution 1 is stopped by blocking it. Ma In addition, the patient has the luxury of waiting until the drug solution 1 is completely exhausted and notifying the nurse. This eliminates the wasted waiting time that occurred when replacing the drug solution bottle 2, and Therefore, it is possible to eliminate the waste of discarding the remaining chemical solution 1. And, it has an extremely simple structure, just providing a floating stopper 6 to the drip tube 4 or medicine bottle 2. Therefore, it has many useful effects such as low cost and no failure.
