Description

Closed suction-free self-contained solvent medicine bottle

technical field

The utility model relates to the field of medical supplies, in particular to a closed suction-free medicine bottle with a self-contained solvent.

Background technique

The current chemotherapeutic drug preparation method is as follows:

Aspirate the solution with a syringe --> inject into the medicine bottle --> draw up the medicine solution in the medicine bottle with a syringe --> inject the medicine solution into the infusion bottle/bag.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

In order to make the drug preparation easy and the drug is leak-free, a closed non-suction self-contained solvent medicine bottle, the closed non-suction self-contained solvent medicine bottle includes a piston 1, a spacer layer 11 and a bottle body 3 with an opening at one axial end, the piston 1. Close the opening of the bottle body 3 and move along the axis of the bottle body 3. The spacer layer 11 is arranged inside the bottle body 3 and is perpendicular to the axis of the bottle body 3. The medicine chamber 6 is formed inside the bottle body 3 on one side of the spacer layer 11. On the other side of the layer 11, a solvent chamber 4 is formed between the bottle body 3 and the piston 1. The solvent chamber 4 and the drug chamber 6 are isolated from each other and can be communicated when the piston 1 compresses the solvent chamber 4. Set the medicine 7 in the medicine chamber, and the solvent 5 in the solvent chamber. When dispensing the medicine, push the piston 1 hard, the solvent chamber 4 communicates with the medicine chamber 6, and the solvent 5 enters the medicine chamber 6, and oscillates the solvent 5 of the whole device to quickly dissolve the medicine 7. Dispensing is complete. The whole process is easy to operate, and the solvent 5 and medicine 7 are always located in the closed bottle body 3 without the possibility of leakage.

The spacer layer 11 can be arranged in a variety of ways, and the structure of the whole device and the operation mode during dispensing will be different in different ways. The spacer layer 11 can be easily broken and connected with the bottle body 3, but it is best not to be easily broken, and there should be a small number of difficult to break the connection, so that the piston 1 is easily broken and connected, and the spacer layer 11 is inclined so that the spacer layer 11 is connected to the bottle body 3. There is a gap between them, the gap is large, the solvent 5 enters the drug chamber 6 due to its own gravity, and dissolves the drug 7 (due to the existence of air pressure, the piston 1 is difficult to push, so the solvent 5 can only enter the drug chamber 6 by its own gravity). After the dispensing is completed, the medicine needs to be output by pushing the piston 1, and the piston 1 can only be pushed to the spacer layer 11, so the total volume of the air in the solvent chamber 4 and the medicine chamber 6 should be greater than the volume of the solvent chamber 4 in this way , so that the prepared medicine can be fully exported.

The spacer layer 11 may also be provided with a destructible structure or a one-way valve. Push the piston 1 to destroy the destructible structure or open the one-way valve to form a channel connecting the solvent chamber 4 and the drug chamber 6. This channel is relatively small, and the solvent 4 relies on its own gravity Entering medicine cavity 6 can be very slow. Therefore, the bottle body 3 needs to be provided with an air release hole 2, and the upper part of the drug chamber 6 is connected with the air release hole 2. Because the air in the drug chamber 6 can be discharged from the air release hole 2, the piston 1 can continue to push the solvent 5 into the drug chamber 6 . The position where the medicine cavity 6 communicates with the vent hole 2 should make the volume of the medicine cavity 6 below the position greater than the volume of the finished medicine, so as to prevent the solvent 5 from entering the air discharge channel. As mentioned above, after the dispensing is completed, the medicine needs to be output by pushing the piston 1, and the piston 1 can only be pushed to the spacer layer 11, so the total volume of the air in the solvent chamber 4 and the medicine chamber 6 should be Greater than the sum of the volumes of the solvent chamber 4 and the solvent 5, the medicine prepared can be completely output like this. Use your fingers to block the vent hole 2 when outputting the medicine. Vent hole 2 should be closed before dispensing, so as to avoid that medicine 7 falls out or is polluted, film can be pasted on bottle body 3 to cover vent hole 2, and throw off film when dispensing and get final product.

The bottle body 3 can be provided with a piston limiting structure 12 at one end of the piston 1, so as to prevent the piston 1 from being accidentally pulled out.

The medicine 7 and the solvent 5 can be added to the medicine bottle afterward, or the medicine bottle can be made so that it can be added to become a part of the medicine bottle. After the medicine 7 and the solvent 5 are added to the medicine bottle, the piston 1 is required to pull out the bottle body 3, so that the piston limiting structure 12 should be detachably connected with the bottle body 3, so that the solvent 5 can be added; the bottle body 3 surrounds the medicine cavity 6 The part should be detachable, for example divided into two parts screwed together, so that the drug 7 can be added. Make this medicine bottle and add medicine 7 and solvent 5 then the structure of the present utility model can be relatively simple, but must do the sign of internal medicine well on bottle body 3, and different medicine bottles are used for treating different diseases.

As previously mentioned, the prepared medicine also needs to be discharged from the bottle body 3 and input into the infusion bottle or infusion bag. The output device is usually the injection needle 8, which can be installed separately when the injection needle 8 can output the medicine, and can also be included in the utility model. , the injection needle 8 communicates with the drug cavity 6 . In order to avoid drug leakage, a valve 10 is provided between the injection needle 8 and the drug cavity 6 .

In order to prevent the injection needle from hurting people and further prevent drug leakage, the needle end of the injection needle 8 is provided with a protective sleeve 9 .

In order to facilitate the control of the output volume of the medicine, the bottle body 3 is provided with a volume mark indicating the volume of the medicine chamber 6 .
