Embodiment 1

[0034] see Figure 1-3, a closed compounding device for antineoplastic drugs, comprising a cylinder 2 with open ends and an inner diameter larger than the outer diameter of a vial 1, one end of the cylinder 2 is provided with a cap seal for the end of the cylinder 2 The sleeve cap 3, the inner wall of the cylinder body 2 is provided with a flange 4 that can hold the neck of the vial 1, the flange 4 is located near the end of the cylinder body 2 with the sleeve cap 3, the flange 4 is made of elastic material; one end of the sleeve cap 3 is open, the other end has a top cover, and a connecting pipe 5 is fixed in the middle of the top of the sleeve cap 3; The central axis and the central axis of the cylinder body 2 are on the same straight line, and the needle point of the injection needle tube 6 passes through the top cover of the sleeve cap 3 and extends to the middle of the cylinder body 2; the end of the connecting pipe 5 far away from the sleeve cap 3 is provided with a The...

Embodiment 2

[0046] see Figure 1-5 , a method for using a closed preparation device for antineoplastic drugs, comprising the steps of:

[0047] S1. Insert the end of the vial 1 with the cap from the open end of the cylinder 2 without the cap 3 into the cylinder 2, push the vial 1 so that the inner flange 4 of the cylinder 2 blocks the vial 1 and the tip of the injection needle tube 6 inside the cap 3 is gradually inserted into the inner cavity of the vial 1, and the through hole 12 is kept outside the vial 1 to balance the air pressure in the vial 1;

[0048] S2. Gradually insert the injection needle tube 6 into the vial 1 until the through hole 12 is located in the inner cavity of the vial 1 and close to the inner wall of the bottle cap, insert the nipple of the syringe 14 that has extracted the solvent liquid into the pintle 7, and push the syringe 14 The piston push rod makes the solvent liquid in the syringe 14 enter the vial 1 through the inner cavity of the connecting tube and the ...

Abstract

The invention relates to the field of a medical apparatus, and discloses a closed type preparation device for antitumor medicines and a using method of the closed type preparation device. The closed type preparation device comprises a cylinder body and a sleeving cap, wherein flanges are arranged on the inner wall of the cylinder body, and are made from an elastic material; a connecting pipe is fixed to the middle of the top of the sleeving cap, an injection needle coxially arranged at the end head close to the sleeving cap, of the connecting pipe, and a needle point of the injection needle penetrates through the top cover of the sleeving cap and extends to the middle of the cylinder body; a pintle is arranged at the end head away from the sleeving cap, of the connecting pipe; and the injection needle and the pintle communicate with an inner cavity of the connecting pipe. A penicillin bottle is inserted into the cylinder body, the injection needle on the inner side of the sleeving capis punctured into the penicillin bottle, the flanges in the cylinder body are used for clamping the neck of the penicillin bottle, solvent liquid is injected to the penicillin bottle through the injection needle, and the cylinder body is held by the hands for shaking up medicament in the penicillin bottle, so that the condition that during the process, the liquid in the penicillin bottle can splash to air, can be avoided, the condition that medicines damage mucosa or skin of medical personnel can be avoided, and generation of needling wound can be avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a closed preparation device for antineoplastic drugs and a usage method thereof. Background technique [0002] A vial is a small glass container used to hold powder or liquid medicine. Its structure includes a bottle body and a bottle head, and a neck located in the concave part between the bottle body and the bottle head. The capacity is generally 1-20ml. It is generally used for For injection medicine liquid or medicine powder, the bottle cap of the bottle head is generally made of rubber with a rubber stopper, and a layer of metal aluminum foil is set outside the rubber stopper for sealing. [0003] At present, when using traditional dispensing methods to prepare anti-tumor drugs in vials, the syringe is generally used to suck the solvent from the infusion bag or bottle, and then the needle of the syringe is inserted into the vial to inject the liquid into the vial, and the vial...
