Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a negative pressure box for mixing infusion fluids. In other words, when a drug solution stored in an ampoule is collected by suction into an infusion drip bottle containing Ringer's solution, glucose solution, etc. and mixed, the medicine should be suctioned and collected even if the infusion drip bottle is a plastic bottle. This article relates to a negative pressure box that can be used for things that can.

(Prior art) In general, infusions such as Ringer's solution or glucose solution are often mixed with medicinal solutions such as antibiotics, cardiotonic agents, vasodilators, vitamins, etc., and administered to patients. Currently, the work of mixing ~10 ampules of liquid is done manually using a syringe. That is, for each ampoule, the process of cutting the neck of the ampoule, drawing out the infusion liquid with a syringe, inserting the needle of the syringe into the rubber stopper of the infusion bottle, and injecting the liquid into the infusion bottle is repeated.

In such operations, since the infusion bottle is sealed, internal pressure is applied during injection, and the injection operation must be performed while removing air from the infusion bottle. Therefore, there was an inconvenience in that it required a great deal of effort, skill, and time.

Japanese Utility Model Application Publication No. 53-34189 and Japanese Utility Model Application No. 54-167590, etc. improve on the above points by connecting the suction tube to an aspirator, inserting the needle of the suction tube into the infusion bottle, and dispensing the medicinal solution in the ampoule. A method is disclosed in which the liquid is suctioned and injected into an infusion bottle while reducing the pressure.

(Problems to be solved by the invention) The devices disclosed in Japanese Utility Model Application Publication No. 53-34189 and Japanese Utility Model Application Publication No. 53-167590 both contain infusion bottles made of hard materials such as glass bottles. It is a suction injection, and it was possible to suction it under reduced pressure under normal conditions.

However, in recent years, there has been a tendency for a large number of plastic bottles to be used, and if you try to apply negative pressure to these plastic bottles, the bottles will become deformed.
There is a drawback that suction cannot be achieved.

Therefore, the technical problem of the present invention is to provide a negative pressure box for mixing infusions that can be used to inhale under reduced pressure even into soft plastic bottles.

(Means for Solving the Problem) The technical means of the present invention for solving the above-mentioned technical problems is to provide a plastic bottle with an opening for passing an injection tube and a suction tube that communicate with the bottle mouth. This is a negative pressure box for mixing infusion fluids that can maintain airtightness and is equipped with a suction port to create a negative pressure inside the box to prevent deformation, and is also equipped with an opening/closing lid to allow plastic bottles to be taken in and out.

(Effect of the invention) According to this technical means, the opening/closing lid is opened, a plastic bottle is inserted into the box body, the lid is closed, and the needles of the injection tube and suction tube passed through the opening are inserted into the rubber stopper of the plastic bottle. When inserted into the ampoule, the medicinal solution is sucked and injected into the plastic bottle while being depressurized.

At that time, the box itself can be kept airtight by suctioning negative pressure from the negative pressure suction port provided on the box body, so the negative pressure inside the box and the negative pressure inside the plastic bottle are balanced. It can prevent plastic bottles from deforming.

In this way, it is possible to mix injections while preventing the bottle from deforming, and the bottle will not deform and make it impossible to inhale the medicinal solution from the ampoule.

(Example) The embodiments shown in the drawings will be described below.

1 is a negative pressure box main body, 2 is a suction port for negative pressure formed on the side of the negative pressure box main body, and 3 is an opening/closing lid for putting in and out a plastic bottle 4, in order to keep the inside of the main body airtight. Tightening fitting 6 via rubber packing 5
The lid can be tightened with the button.

The lid 3 has an opening 7 corresponding to the bottle mouth 4a.

The plastic bottle 4 is placed on a spacer 8 to adjust the height of the bottle, and a ring-shaped rubber gasket 9 is placed between the bottle opening 4a and the lid 3.
is interposed.

Reference numeral 10 denotes an injection tube, one end of which is inserted into the medicinal solution of the ampoule, and the other end of which is an injection needle 10a inserted into a rubber stopper 12 at the mouth of the bottle.

13 is a suction tube, one end is an electric suction device 1
4, and the suction needle 13a at the other end is inserted into the rubber stopper 12 at the mouth of the bottle.

Both the injection needle 10a and the suction needle 13a are inserted into the rubber plug 12 using the hole 9a of the ring-shaped rubber gasket 9.
inserted into.

As shown in the figure, the air in the negative pressure box 1 in which the plastic bottle is set is sucked through the negative pressure suction port 2 via an aspirator (not shown), while the air in the bottle 14 is sucked through the suction tube 13 from the aspirator 14. The liquid medicine in the ampoule 11 is then injected into the injection tube 1.
0 into the bottle 4 without causing any deformation of the bottle.

At this time, if the negative pressure inside the bottle is A and the negative pressure inside the box is B, then A≦B, and the bottles can be mixed without being deformed.

In addition, if a part of the box body is made transparent for monitoring purposes, the status of mixed injection can be seen. The shape of the box may be such that one side of the box is entirely transparent, or it may be window-shaped.

Transparent material can also be used to shield the bottle from light, such as translucent or colored transparent or translucent film.

Further, the opening/closing lid for taking in and out the bottle may be provided not only on the top of the box as shown, but also on the side as shown in FIG. 3.

A spring base 18 and base plates 16, 1 shown in FIG.
A screw type height adjustment table 21 shown in FIG. 5, which has a screw rod 19 and a screw cylinder 20 between the screws 7 and 7, is used, but its design is arbitrary.

The negative pressure of this invention can also be used in a chemical liquid collection device as disclosed in Japanese Patent Application No. 78800/1983.
