Description

Description Device for filling drugs into infusion drip bottles

The present invention relates to a device S for semi-automatically packing an infusion drug solution contained in a small bottle into an infusion bottle containing an infusion solution such as Ringer's solution or glucose solution. Background art

Conventionally, the operation of packing the infusion drug solution in a small bottle or the like into the infusion drip bottle is performed manually using a syringe. This conventional manual method will be described with reference to FIGS. 1 and 2. FIG.

As shown in FIG. 1, the needle 5 of the syringe 4 is inserted into the rubber stopper 3 of the dispenser bottle 1 containing the drug solution 2, and the drug solution 2 is removed.

At this time, there is considerable air 6 leaking from the surroundings in the syringe 4. This air is forced out of the syringe before the next operation. This is because, in the presence of air, the pushing force of the syringe's bistone does not directly apply to the liquid when pushing out the liquid, and the content of the syringe is substantially reduced, resulting in inefficiency.

Next, as shown in FIG. 2, the needle 5 of the syringe 4 is used to pack the drug solution 2 drawn into the syringe 4 into a drip bottle 7 containing a ring fluid 8 such as Ringer's solution or glucose solution. Is inserted into the rubber stopper 9 of the drip bottle 7, the drug solution 2 is injected, and then the needle 5 is removed. Note that 10 in the drip bottle 7 is a thin tube for venting air.

Perform the operations shown in Figs. 1 and 2 for each drug solution to be packed in a drip bottle. In this way, the filling of the solution into the drip bottle is completed. However, the above conventional methods have the following disadvantages.

(1) Each time one type of drug solution is packed into one drip bottle, the drug solution is removed by a syringe and the injection operation is performed 4 times on each side, so if there are several types of drug solutions, several In the case of drip infusion of a large number of medicaments, more than one hundred or more hundreds of syringes need to be pulled and pushed with one hand, so the labor is large and the working time is long.

(2) Manual operation with a syringe is a one-handed operation and requires ripe ripening.

(3) If the number of times the syringe is punctured increases, the chance of bacterial invasion increases with the air leaking at that time, and the infusion will be infected.

(4) Since the number of surfaces for inserting the injection needle into the drip bottle is large, many needle holes remain in the rubber stopper of the drip bottle, and when the drip bottle is used upside down, liquid leakage occurs.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to semi-automate the work, reduce labor and work time, and provide a sanitary and safe drug for infusion bottles for infusion without the risk of bacterial invasion and liquid leakage. To provide a packing device. Disclosure of the invention

The present invention provides a device for generating and supplying a suction gas instead of a conventional manual operation of sucking and pushing out a liquid by a manually operated syringe, and a device for concealment and a drip bottle containing a liquid for a liquid. And an injecting needle at the terminal for connecting the drip bottle and the drug bottle containing the drug solution, and a pipe for feeding a suction gas and a pipe for feeding a drug solution provided with an opening / closing cock on the way. Using the suction force of the suction gas, the medicine liquid is semi-automatically filled into the drip bottle while controlling the gas absorption and the liquid supply by manual operation of the opening / closing cock. The device that generates and supplies the absorbed gas contains a suction-adjustable air generator that can adjust the pressure, as well as external suction such as a secretion suction facility that is piped in a hospital or a portable small secretion suction device. This device is equipped with a means for receiving gas, adjusting its pressure, and supplying the gas. The device of the present invention stimulates the rubber stopper of each bottle of the injection needle attached to the end of each pipe,

gAD ORIGIN At Only the pulling-out operation and the opening / closing operation of the opening / closing cock provided on each pipe are performed manually.

All other operations are performed automatically. BRIEF DESCRIPTION OF THE FIGURES

WIPO. V This is a chemical and chemical picture transfer pipe (hereinafter referred to as pipe 20) having an injection needle 22 for piercing the rubber stopper 3 of the MM 1 and an opening / closing cock 23 on the way. One pipe 20 is prepared for each drip boat 7, and when the supply of one kind or several kinds of chemical liquid required for 1 舰 drip bottle is completed, it is replaced from a sanitary point of view with a new one. .

(2) Next, a method of using the present apparatus will be described. As shown in Fig. 3, the needle 1 at the end of the pipe 16 is injected into the rubber stopper 9 of the drip bottle 7, and the needle 21 at the end of the pipe 20 is infused. Inject the rubber stopper 9 in the bottle 7 and the injection needle 22 attached to the other end into the bottle stopper 3 in the required drug bottle 1.

The open / close cocks 18 and 2 for pipes 16 and 20 are closed.

When the suction gas supply line device S I 1 is activated, the suction gas adjusted to the optimum pressure is the cock of pipe 16! Sent up to _8. Next, the cock 18 is opened, and then the cock 23 of the pipe 20 is opened, and the drug solution 2 in the medicine bottle 1 is drawn through the pipe 20 by the suction gas pressure in the drip bottle 7 so that the inside of the bottle 7 is dropped. The liquid is sucked and injected into, and mixed with some liquid 3.

When the injection is completed, close cock 23 and then remove needle 22. If it is necessary to pack another medicine ^! Solution, the same operation is performed by stimulating the injection needle 22 into the rubber stopper of the bottle of the medicine solution, and performing the same operation as in the case of one medicine bottle. After the packing is completed, close the cock 18 of the pipe 16 and remove the injection needles 17 and 2 1-of the pipes 16 and 2 Q inserted into the rubber stopper 9 of the drip bottle 7. In this manner, the filling of the drug into the drip bottle of U1 is completed. This filling operation is performed for a required number of drip bottles. Industrial applications

As described above, according to the present invention, the following effects are obtained.

(1) Elimination of the labor and skill required for liquid injection using a conventional one-handed syringe is eliminated, and work time is significantly reduced.

(2) When filling one type of drug solution into a drip bottle, the conventional method pierces and removes the syringe.

BAD OBiniMM ^

^ 'O PI In contrast, two samples were taken (one for the drug bottle and one for the infusion bottle), but only one surface was used in the present invention. And the chances of contact are reduced and more sanitary. .

(3) In the conventional method, the number of piercing surfaces of the injection needle into the drip bottle is the same as the number of drug types, but in the present invention, only one surface is required regardless of the number of drug types. The number of needle holes remaining in the needle is extremely small (two), so no liquid leakage will occur even if the bottle is turned upside down when using a drip bottle.

(4) Since the god can be concentrated only on the manual work of opening and closing the cock and pulling out the injection needle, each operation can be performed continuously in a flowable manner.
