Embodiment 3

[0051] Penicillin 800,000 U / bottle,

[0052] Existing method prepares penicillin skin test solution:

[0053] In the first step, take 4ml of normal saline with a 10ml syringe and insert it into a 800,000 U penicillin bottle to dissolve the penicillin to obtain a 200,000 U / ml penicillin liquid;

[0054] In the second step, use a 1ml skin test syringe to insert into the dissolved 800,000 U penicillin bottle to take 0.1ml of 200,000 U / ml penicillin liquid, pull it out, insert it into a normal saline bottle, and inhale normal saline to 1ml to obtain 20,000 U / ml of penicillin liquid;

[0055] The third step is to discharge 0.9ml of the 20,000 U / ml penicillin liquid in the 1ml skin test syringe, and then insert the normal saline bottle to inhale the normal saline to 1ml to obtain the 2,000 U / ml penicillin liquid;

[0056] Step 4: Discharge 0.75ml of the 2,000U / ml penicillin liquid in the 1ml skin test syringe, then insert the normal saline bottle and inhale the normal saline to 1ml...

Abstract

The invention relates to a skin test solution preparation device and a method for preparing a skin test solution. The skin test solution preparation device comprises an injector cylinder and an injector piston inserted in the injector cylinder. The injector cylinder is composed of a main cylinder body and a micro measurement cylinder body which is connected to the front end of the main cylinder body, and the front end of the micro measurement cylinder body is connected with a syringe needle. The injector piston is composed of a main piston body and an auxiliary piston body. An auxiliary piston cavity is formed in the main piston body, and the auxiliary piston body is inserted in the auxiliary piston cavity. The rear end of the main piston body is connected with a main piston rod, the rear end of the auxiliary piston body is connected with an auxiliary piston rod, an inner cavity is formed in the main piston rod in the axial direction, the auxiliary piston rod penetrates through the inner cavity, and the auxiliary piston body is matched with the micro measurement cylinder body. According to the skin test solution preparation device and the method for preparing the skin test solution, steps of skin test solution preparation are simplified, the probability of solution pollution is reduced, operation frequency is reduced, preparation precision is improved, and errors cannot occur easily; measurement is accurate, there is no residue or bubble or bacterium when the solution is emptied by the preparation device, and operation is convenient and quick.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a skin test solution preparation device and a method for preparing the skin test solution. Background technique [0002] In the prior art, it usually takes 4 steps to prepare the skin test solution. It needs to use the syringe to suck the drug solution many times, which is easy to be polluted, and the precision of the drug dispensing is not enough, and the operation is inconvenient. [0003] Take the penicillin skin test solution as an example, the penicillin is 800,000 U / bottle. [0004] In the first step, take 4ml of normal saline with a 10ml syringe and inject it into a 800,000 U penicillin bottle to dissolve the penicillin to obtain a 200,000 U / ml penicillin liquid; [0005] In the second step, use a 1ml skin test syringe to insert into the dissolved 800,000 U penicillin bottle and take 0.1ml of 200,000 U / ml penicillin solution, pull it out and then insert it into the normal...
