Description
Technical Field
[0001] The utility model relates to the field of food packaging, in particular to an infusion bag that can directly add medicine. Background Art
[0002] A vial is suitable for storing powders and granular substances, such as vaccines, biological agents, powder injections, freeze-dried drugs, etc. When in use, a certain amount of solvent needs to be first drawn into the vial with a syringe, the powder drug is dissolved by shaking, and then the dissolved medicine is drawn out with a syringe and injected into the infusion bag. The whole operation process is complex and requires repeated extraction with a syringe, which is likely to cause drug contamination. In the existing infusion bag, a medicine adding tube with a rubber plug is designed on the bag body for the syringe to insert for adding medicine. During the insertion process of the syringe, drug contamination may also be caused, and direct medicine addition from the vial cannot be achieved. Content of the Utility Model
[0003] The purpose of the utility model is to provide an infusion bag that can directly add medicine and solves the above problems.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an infusion bag that can directly add medicine, including an infusion bag and a vial to be medicated. A medicine adding connector is provided at the upper end of the infusion bag. A groove matching the head of the vial is opened at the top of the medicine adding connector. An insertion needle is vertically provided in the groove. The vial to be medicated is inserted into the groove at the top of the medicine adding connector through the insertion needle. A needle hole is provided in the insertion needle, and the medicine in the vial is input into the infusion bag through the needle hole. A cover body is provided at the top of the medicine adding connector, and the cover body is detachably connected to the medicine adding connector.
[0005] Preferably, the infusion bag is a disposable infusion bag pre-filled with physiological saline.
[0006] Preferably, a circular ring of limiting claws is provided around the top of the medicine adding connector, and the limiting claws are closely attached to the periphery of the inserted vial.
[0007] Preferably, the cover body is a screw cap, and external threads matching the screw cap are provided around the medicine adding connector, and it is rotationally detachably connected to the screw cap through external threads.
[0008] Preferably, the infusion bag is made of soft-shell plastic.
[0009] Preferably, a hanging strap is provided on the infusion bag.
[0010] Compared with the prior art, the advantages of the utility model are as follows: The infusion bag of the utility model can be used for directly adding medicine to a vial. During use, only need to align the rubber cap at the head of the vial with the insertion needle on the medicine adding connector, insert the vial on the medicine adding connector, then slightly tilt the head of the infusion bag downward, squeeze the normal saline in the infusion bag into the vial, and repeatedly squeeze several times to dissolve the powder medicine. Then stand up the infusion bag, squeeze the air in the upper part of the infusion bag into the vial, and at the same time, the dissolved medicine in the vial is sucked into the infusion bag under negative pressure, thus completing the dissolution and addition of the medicine. The whole process is very convenient and fast, does not require repeated pumping with a syringe, and is not easy to cause medicine pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will further illustrate the utility model as follows: An infusion bag capable of directly adding medicine, see Figures 1 to 4, including an infusion bag 1 and a vial 5 to be medicated. The upper end of the infusion bag 1 is provided with a medication connection head 2. The top of the medication connection head 2 is provided with a groove 23 that matches the head of the vial 5. A needle 21 is vertically arranged in the groove 23. The vial 5 to be medicated is inserted into the groove 23 at the top of the medication connection head 2 through the needle 21. A needle hole is arranged in the needle 21, and the medicament in the vial 5 is input into the infusion bag 1 through the needle hole. The infusion bag 1 of the present utility model can be used for directly medicating the vial 5. During use, only need to align the rubber cap at the head of the vial 5 with the needle 21 on the medication connection head 2, insert the vial 5 on the medication connection head 2, then slightly tilt the head of the infusion bag 1 downward, squeeze the normal saline in the infusion bag 1 into the vial 5, and squeeze it several times repeatedly to dissolve the powder medicament. Then stand up the infusion bag 1, squeeze the air in the upper part of the infusion bag 1 into the vial 5, and at the same time, the dissolved medicament in the vial 5 is sucked into the infusion bag 1 under negative pressure, and the dissolution and medication of the drug can be completed. The whole process is very convenient and fast, does not require repeated pumping with a syringe, and is not easy to cause medicament pollution.
[0017] The design of the groove 23 can play a role in positioning and guiding during the insertion of the vial 5. When inserting, the head of the vial 5 can be clamped on the medication connection head 2. After the needle 21 is inserted into the rubber cap at the head of the vial 5, the rubber cap has a certain resistance, which can also prevent the needle 21 from falling off.
[0018] In order to avoid external pollution of the needle 21 part, a cover 3 is provided at the top of the medication connection head 2. The cover 3 is detachably connected to the medication connection head 2. The plugging part can be sealed through the cover 3. When in use, just unscrew it to carry out plugging and medication. The cover 3 is a screw cap. The periphery of the medication connection head 2 is provided with an external thread that matches the screw cap, and it is rotationally detachably connected through the external thread and the screw cap.
[0019] The infusion bag 1 is a disposable infusion bag 1 pre-filled with normal saline, without the need to add normal saline. It can be used for infusion after adding the medicament, which is very convenient.
[0020] A ring of annular limit claws 22 is provided around the top of the medication connection head 2. The limit claws 22 are closely attached to the periphery of the inserted vial 5. The design of the limit claws 22 is convenient for limiting and clamping the vial 5 after insertion. The infusion bag 1 is made of soft-shell plastic, and the soft-shell plastic has a certain resilience so as to generate negative pressure when squeezed to suck the medicament into the infusion bag 1. A hanging strap 4 is provided on the infusion bag 1, and it can be hung on an infusion rack through the hanging strap 4 for use.
[0021] The above has introduced in detail a transfusion bag capable of directly adding medicine provided by the present utility model.
