In order to solve the technical problem, the utility model adopts the following technical scheme:
a closed device for preparing chemotherapeutic drugs comprises a solid drug puncture needle, a liquid drug puncture needle, a three-way pipe, a drainage device, a joint and a liquid drug measuring device, wherein the solid drug puncture needle is communicated with a first end of the three-way pipe through a first conduit, the liquid drug puncture needle, the liquid drug measuring device and a second end of the three-way pipe are sequentially communicated through a second conduit, a third end of the three-way pipe is communicated with one end of the joint through a third conduit, and the other end of the joint is communicated with the drainage device capable of sucking and releasing liquid; the first catheter is clamped with a first catheter clamp, the second catheter is clamped with a second catheter clamp and a liquid medicine fixing clamp, and the second catheter clamp and the liquid medicine fixing clamp are respectively located on two sides of the liquid medicine measuring device and clamped at the head end and the tail end of the liquid medicine measuring device.
Preferably, the head end of the solid medicine puncture needle is connected to a medicine bottle or a medicine bag filled with solid medicines; the head end of the liquid medicine puncture needle is connected to a medicine bottle or a medicine bag filled with liquid medicine.
Preferably, the medicine bottle or the medicine bag is provided with a puncture opening, and the solid medicine puncture needle and the liquid medicine puncture needle can be connected to the puncture opening in a penetrating manner.
Preferably, the drainage device is a drainage ball or a syringe.
Preferably, the drainage ball is a transparent ball.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the utility model discloses a closed device, the effectual drawback that splashes with the contact of outside air and liquid when having avoided the operation has still designed liquid medicine scale simultaneously and has shown.
The utility model discloses not only be the closed device, and can realize the purpose that solid and liquid mix or liquid and liquid mix inside the device, the principle is through the gas that can pass through in the drainage ball when tightening up and releasing at the drainage ball produces pulling force or promotion to liquid, thereby can control through simple operation according to the quantity that patient used medicine, can extract quantitative liquid medicine earlier at the in-process of configuration medicine, mix in by propelling movement to solid medicine bottle again, send into the mixture to liquid medicine bottle in the lump at last, whole operation is in inclosed device, consequently, do not lead to liquid to splash with the air contact yet, and realized making the directional flow of liquid and mix in the controlled way, the requirement to the configuration medicine in the prior art liquid has been realized at last.
The utility model discloses a liquid medicine scale shows, and the purpose is that the quantitative liquid medicine is got earlier to tighten up and loose through the drainage ball put with solid medicine and liquid medicine intensive mixing, then will dissolve mixed liquid after again and lead to in the liquid medicine bottle. Repeated tightening and loosening operations can be performed through the drainage ball, so that the solid medicine and the liquid medicine are fully mixed, and the solubility of the solid medicine is improved.
