It is designed to have a capacity such that a fixed amount, for example, 100 ml of the lysate can flow in. The drug contained in the drug container 2 is preferably a powdered drug, for example, cefazolin sodium, ceftizoxime sodium, cefotiam hydrochloride, cefmenoxime hydrochloride, cefacetril sodium, cefamandole sodium, cephaloridine, cefotaxime sodium, Cefotetan sodium, cefoperazone sodium, cefsulodin sodium, ceftezol sodium, cefpyramide sodium, cefmetazole sodium, cefuroxy sodium, cephem antibiotics such as cefocles sulfate, ampicillin sodium,
Examples include penicillin antibiotics such as carbenicillin sodium, sulbenicillin sodium, and ticarcillin sodium, antitumor agents such as mitomycin C, fluorouracil, tegafur, cytarabine, and antiulcer agents such as famotidine, ranitidine hydrochloride, and cimetidine. For these drugs that are unstable to light, it is preferable to cover the drug container 2 with a light-shielding film.

A first tube 3 is connected to a substantially central portion of the edge portion 2a of the medicine container 2. When forming the medicine container 2, the tube 3 is connected to the medicine container 2 by heat-sealing together with the edge portion 2a. The tube 3 is a tube made of synthetic resin having soft flexibility and transparency (for example, polyvinyl chloride, Teflon, polyethylene, etc.). An opening / closing cock 4, a connecting member 5, and a puncture needle 6 are sequentially connected to the tube 3 from the side closer to the drug container 2. The opening / closing cock 4 regulates the inflow of the solution into the drug container 2. The pipe 3 of the tube 3 is closed before the drip container 1 is used, and the knob 4a is rotated when the drip container 1 is used. The solution is opened to allow the solution to flow into the medicine container 2. The opening / closing cock 4 may also have a function of adjusting the amount of the solution to be dropped onto the drug container 2, like a flow rate cock 8 described later.

The connecting member 5 is made of synthetic resin and has projections 5a and 5b at both ends as shown in FIG.
The tube 3 to which the puncture needle 6 is connected is connected to, and the tube 3 to which the opening / closing cock 4 is connected is connected to 5b. Inside the protrusions 5a and 5b and inside the main body of the connecting member 5, a channel for the dissolving liquid is provided. Connection member 5
