Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a drip container such as a glass or plastic drip pin or a plastic film drip bag. The present invention relates to a method for filling an infusion container with an infusion solution.

[Conventional technology]

When performing a drip injection, a glass or plastic drip pin containing Ringer's solution, glucose solution, etc. may be filled with a specific drug depending on the patient's individual medical condition.

In this case, the work of loading the drug into the drip pin is
Conventionally, this has been done manually using a syringe, in which the drug solution inside the medicine pin is sucked out with the syringe and then injected into the drip pin.

However, when there are many types and amounts of drugs, the process of inhaling and injecting the drug solution with a syringe must be repeated many times.
In particular, when preparing infusions for dozens of people on day -, a considerable amount of effort and time is required.

Therefore, in order to quickly fill the drug solution, a method was proposed in which the air inside the IV pin was sucked out using a vacuum pump to reduce the pressure, and the drug solution was aspirated through a liquid collection tube connected to the IV pin (Unexamined Japanese Patent Publication No. Publication No. 59-139264).

As shown in FIG. 3, the rubber stopper 32 of the drip pin 31
At the same time, the hollow needle 33a attached to one end of the liquid collection tube 33 is inserted, and the hollow needle 352 of the exhaust pipe 35 connected to the vacuum pump 34 is inserted. 33b into the medicine pin 36 and the vacuum pump 34 is driven, the air inside the drip pin 31 is sucked out and the internal pressure decreases, so the medicine solution is automatically discharged from the hollow needle 33b on the other end of the liquid collection tube 33. The liquid is drawn into the drip pin 31.

However, when this method is applied to a plastic drip pin 31, a problem arises in that the drip pin 31 is crushed by atmospheric pressure.

That is, when the vacuum pump 34 is operated at high output in an attempt to shorten the filling time, the air inside the drip pin 31 is discharged in excess of the amount of drug solution filled through the liquid sampling tube 33. The internal pressure gradually decreases, and the plastic drip pin 31 collapses without being able to withstand the atmospheric pressure, making it impossible to fill it with medical fluid.

In addition, when filling the glass drip pin 31 with a medical solution, when the pressure inside the drip pin 31 is suddenly reduced, the pin 31 itself will not be crushed, but the rubber stopper 32 will be sucked inward and If there is a large dent and a small scratch or crack in the rubber membrane forming the rubber stopper 32, there is a problem that it will burst.

On the other hand, when administering a drip without having to replace the drip pin etc. continuously for a long period of time (one day), instead of using a drip pin, for example, a plastic whose capacity is equivalent to several drip pins (approximately 21) is used. Use an infusion bag made of film bag.

When filling this infusion bag with infusion fluid,
Conventionally, as shown in FIG. 4, a hollow needle 43 at the other end of a liquid collection tube 42 whose one end is connected to an infusion bag 41 and a ventilation needle 44 are inserted into a medicine pin 45, and the medicine pin 45 is placed on a stand. 46
At the same time, the infusion bag 41 is hung at a low position, and the medicinal solution is filled by the drop.

Since the infusion bag 41 has a large capacity, it is necessary to fill the infusion solution with multiple medicine pins, but conventionally, even if multiple medicine pins are hung on the stand 46 and filled at the same time, it is not possible to fill the bag with the medicine by simply using the head. Since it takes at least 5 to 10 minutes just to fill the bags, it takes a long time to prepare infusion bags for many people.

In this case, even if an attempt is made to reduce the pressure by sucking out the air inside the drip infusion bag 41 using a vacuum pump in the same way as when filling an infusion pin with a drug solution, the plastic films on the front and back of the infusion bag 41 are stuck together when the infusion bag 41 is not in use. Because the air inside the bag cannot be sucked out, the infusion bag 4
When the infusion bag 41 is filled with a medical solution and swells, the medical solution may be sucked out, or even if air can be sucked out, the infusion bag 41 may be deformed depending on the amount of air sucked out. Therefore, the pressure inside the infusion bag 41 is not reduced, and the drug pin 45 cannot be filled with the drug solution in a short time.

[Problem to be solved by the invention]

All of these problems can be solved by directly connecting the drip container to the vacuum pump and sucking out the air inside the drip container.
This is caused by trying to reduce the pressure inside the drip container.

Therefore, the present invention aims to reduce the pressure inside the drip container without directly connecting the drip container with a vacuum pump, and by solving this problem, the first objective of the present application is to The second aspect of the present application aims to provide an infusion solution filling method for an infusion container that can fill an infusion solution in a short time without crushing the infusion pin or bursting the rubber stopper even when an infusion pin is used as the container. The purpose of
The purpose of the present invention is to provide an infusion solution filling method for an infusion container that can reduce the pressure inside the infusion solution bag and fill the infusion solution in a short time even when an infusion solution bag made of a plastic film bag is used as an infusion container. do.

[Means to solve the problem]

In order to achieve the above first object, the first invention of the present application has the following features:
In an infusion solution filling method for an infusion container in which an infusion solution is filled from an infusion container into an infusion container through a collection tube, when the infusion container is an infusion pin, one end of the infusion tube is connected to the infusion container, and one end of the infusion pin is connected to the infusion container. The infusion pin is housed in an airtight tank with the hollow needle for filling the infusion solution attached to the other end of the liquid collection tube and the hollow needle for venting air that makes a hole in the rubber stopper being inserted through the rubber stopper. , the airtight tank is depressurized to suck out the air in the drip pin, thereby sucking and filling the infusion liquid in the infusion container into the drip pin through the liquid collection tube.

In addition, in order to achieve the above second object, a second invention of the present application provides an infusion solution filling method for an infusion container in which an infusion solution is filled from an infusion container into an infusion container through a liquid collection tube, wherein the infusion container is made of a plastic film. In the case of a formed drip infusion bag, one end of the liquid collection tube is connected to the infusion container, and the other end of the liquid collection tube is connected to the drip infusion hang. The infusion bag is housed in an airtight tank, and the pressure inside the airtight tank is reduced to make the infusion bag into a pig, so that the infusion in the infusion container is suctioned and filled into the infusion bag through the liquid collection tube. It is characterized by

[Effect]

According to the first invention of the present application, when the airtight container is depressurized, the air inside the drip pin is sucked out through the air venting hollow needle inserted into the drip pin housed in the airtight container, and the pressure is reduced. , the infusion can be forcibly drawn from the infusion container through the liquid collection tube and filled in a short time.

At this time, the rubber stopper of the IV pin is pierced by a hollow needle for air removal, and the air inside the IV pin is sucked out into the airtight container through the hollow needle, so that the pressure inside and outside the IV pin is equally reduced. Therefore, even if the airtight tank is suddenly depressurized, the drip pin will not be crushed or the rubber stopper will burst, and the infusion can be filled in a short time.

Further, according to the second invention of the present application, when the airtight tank is depressurized, the surrounding pressure is lower than the pressure inside the intravenous infusion bag housed in the tank, so the infusion bag expands due to the pressure difference. The pressure inside the infusion bag is reduced, and the infusion solution can be forcibly drawn from the infusion container through the liquid collection tube and filled in a short time without the need to hang the infusion container at a high position.

[Example I]

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 is a perspective view showing a @liquid filling device used in the present invention. In the figure, 1 is a cylindrical airtight tank connected to a vacuum pump 2 via an exhaust pipe 3, and is made of plastic. A tank body 5 that accommodates a drip pin (drip container) 4 manufactured by
and a lid 7 that closes the upper opening 6.

The tank body 5 is selected to have a size that can accommodate the drip pin 4 with the hollow needle 8 for ventilation and the hollow needle 98 for filling the infusion liquid of the liquid collection tube 9 inserted into the rubber stopper 4a, and the internal situation can be visually checked. For example, it is made of transparent acrylic resin.

Further, the lid body 7 has a through hole 7a formed in the center thereof for leading out the liquid sampling tube 9, and an exhaust boat 7b for connecting the exhaust pipe 3. A two-piece rubber gasket 10 is fitted to airtightly close the through hole 7a with the liquid sampling tube 9 inserted therethrough.

The above is an example of the configuration of an infusion liquid filling device, and next, a method for filling an infusion container with an infusion liquid using this device will be described.

When preparing infusions individually depending on the patient's medical condition in the plastic drip pin 4 containing Ringer's solution or glucose solution, the drip pin 4 is equipped with a hollow needle 8 for air removal and a hollow tube 9 for filling the infusion fluid. The needle 9a is inserted into the airtight tank 1, and the liquid sampling tube 9 is inserted into the through hole 7a of the lid 7 to lead out to the outside, and the through hole 7a is closed with a rubber packing 10.

Then, when the vacuum pump 2 is operated with the hollow needle 9b on the other end of the liquid collection tube 9 immersed in the drug (infusion) of the medicine pin (infusion container) 1), the air in the airtight tank 1 is exhaust pipe 3
The air in the drip pin 4 housed in the airtight tank 1 is sucked out into the airtight tank 1 through the air venting hollow needle 8 stuck in the rubber stopper 4a. , the pressure of the drip pin 4 is reduced to approximately the same pressure as that of the airtight tank 1.

At this time, the infusion container 1) outside the airtight tank 1 is under atmospheric pressure, and the infusion container 1) and the drip pin 4 are connected by a liquid collection tube, so the pressure difference causes the drug to flow into the drip pin 4. is inhaled.

Furthermore, since the pressure on the inside and outside of the drip pin 4 is reduced equally, even if the pressure is suddenly reduced, the drip pin 4 will not be crushed or the rubber plug 4a will not burst, and the infusion can be filled in a short time. .

Furthermore, the air in the airtight tank 1 is sucked by a vacuum pump 3, and even if the intravenous pin 4 is overfilled and the drug overflows, the drug will accumulate in the airtight tank 1, so the vacuum It is not directly sucked into the pump 3, and there is no risk that the pump 3 will malfunction.

In addition, in the description of the embodiment, only the case where a plastic drip pin is used has been described, but it is of course possible to fill the drug solution in the same way even if a glass drip pin is used.

[Example ■]

FIG. 2 is a perspective view showing another embodiment of the present invention, and this embodiment is suitable for filling an infusion solution into an infusion bag 20 made of a plastic film bag. be.

The airtight tank 21 is formed into a box shape from a transparent acrylic plate, and a rubber gasket 24 and a hook 25 for suspending an intravenous infusion bag 20 are attached to the inside of a lid 23 that airtightly closes an upper opening 22. ing.

Further, the lid body 23 is formed with a notch 27 for leading out the liquid collection tube 26 of the drip infusion bag 20 suspended from the hook 25 and housed in the airtight tank 21.

Furthermore, a notch 24a is formed in the rubber packing 24 at a location corresponding to the notch 27, through which the liquid sampling tube 26 is inserted while maintaining an airtight state.

Note that 28a is a through hole through which air is removed by pressing the bag 20 from the outside with a finger or the like when the infusion bag 20 is filled with air, and 28b is a cap for the through hole 28a.

Then, the unused infusion bag 20 is hung on the hook 25 of the lid body 23, the liquid sampling tube 26 is led out through the notch 27, the lid body 23 is closed, and the hollow needle 26a of the liquid sampling tube 26 is connected to the hollow needle 26a of the liquid sampling tube 26. Connect the hollow needle 29 for ventilation to the rubber stopper 1) a of the medicine pin 1).
When the vacuum pump 2 is operated by inserting it into the airtight tank 21,
The air inside is sucked out through the exhaust pipe 3 and the pressure is reduced.

Therefore, the pressure around the infusion bag 20 is lower than the pressure inside the infusion bag 20, so the infusion bag 20 expands.

At this time, the inside of the drip infusion bag 20 is communicated with the outside of the airtight tank 21 through the liquid collection tube 26, so the drug solution in the drug pin ll is vigorously inhaled from the hollow needle 26a at the tip of the liquid collection tube 26. Therefore, the pressure difference causes the drug solution to be quickly filled in a short time without the need to hang the medicine pin 1) at a high place.

Note that if air is inhaled from the hollow needle 26a of the liquid collection tube 26 and enters the infusion bag 20, remove the cap 28b and press the bag with your finger through the through hole 28a to remove the liquid collection tube. The air inside the infusion bag 20 can escape to the outside through the infusion bag 26.

〔Effect of the invention〕

As described above, according to the first invention of the present application, by removing the air in the airtight tank, the air in the IV pin is removed through the hollow needle for ventilation, and the pressure inside the IV pin and the external pressure are reduced. Because the pressure is reduced almost equally, even when filling a plastic IV pin that is easily crushed, it has the excellent effect of being able to fill the IV fluid in a short time without crushing the IV pin or bursting the rubber stopper. There is.

Further, according to the second invention of the present application, by reducing the pressure inside the airtight tank, the infusion bag expands due to the pressure difference between the inside and outside of the intravenous infusion bag made of a plastic film bag, and the inside of the bag is depressurized. The infusion solution can be inhaled through the liquid collection tube, and it has the excellent effect of being able to fill the medicinal solution in a short time without using the head difference between the infusion container and the infusion bag.
