[0002] An injection vial is a container for storing injectable drugs. These bottles are designed to maintain the effectiveness and purity of the drugs and are usually equipped with special rubber stoppers or membranes to facilitate the extraction of drugs using aseptic techniques.

[0003] The injection vial stores drugs (including powders and solvents) for injection. When injection is required, a syringe is used to suck out the drugs in the vial for drug injection. In medical practice, sometimes two or more drugs are mixed together for use, which is usually called "combination drug use" or "drug compatibility". The purpose of drug mixing is to achieve better therapeutic effects, reduce the number of drug administrations, improve patient compliance, etc. To improve the proportioning efficiency of the pharmaceutical and reduce the operation time, some vials and syringes are set together for quick use. However, the current syringe-type vials still have the following problems during use:

[0004] 1. The current vial-type syringe can only store one form of pharmaceutical agent inside, which is not convenient for storing multiple pharmaceutical agents, limiting the scope of use of the vial-type syringe. Although some vial-type syringes are provided with double chambers, the two chambers only have a storage function and cannot mix two pharmaceutical agents. Only the pharmaceutical agents in the two chambers can be sucked out in sequence and then mixed, resulting in a long configuration time for the pharmaceutical agent.

[0005] 2. Since the syringe barrel is composed of a barrel body and a push rod, the overall structure is too long, which is not conducive to the storage and transportation of the injection device.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , an injection medicine bottle and an injection assembly, including a bottle body 101, a needle seat is arranged at the top of the bottle body 101, the bottle body 101 is made of glass, and the glass has good chemical stability, thereby ensuring the effectiveness and safety of the medicine. A vertically arranged medicine cavity 102 is arranged inside the bottle body 101. The vertically arranged medicine cavity 102 is used to store different types of medicaments, such as liquid medicaments or powder medicaments. The first medicament is filled in the bottom medicine cavity 102, and the second medicament is filled in the top medicine cavity 102. The bottom medicine cavity 102 preferably stores liquid medicaments. A partition plate 103 is slidably connected to the inner wall of the bottle body 101 up and down. The partition plate 103 serves to separate the medicine cavity 102. The partition plate 103 is located between the two medicine cavities 102. A through hole 104 that penetrates up and down is opened inside the partition plate 103. A valve piece 105 is arranged at the top of the through hole 104. The valve piece 105 is used to cover the through hole 104, so that the medicament in the bottom medicine cavity 102 can flow to the top medicine cavity 102, but cannot flow in the reverse direction;

[0028] Specifically, refer to Figure 3 and Figure 4, during use, the piston 106 is pushed upward. The piston 106 drives the medicament in the bottom medicine chamber 102 to move upward, enter the top medicine chamber 102 through the through hole 104, and mix with the medicament at the top. The protective gas in the top medicine chamber 102 is discharged from the needle holder at the top. When the partition plate 103 contacts the piston 106, it indicates that the medicament at the bottom has moved into the top medicine chamber 102. At this time, continue to push the piston 106 upward. After discharging the gas in the medicine chamber 102, injection can be carried out.

[0029] Reference Figure 1 and Figure 2 , a piston 106 is provided at the bottom of the bottom medicine chamber 102. A connecting platform 107 is connected to the bottom of the piston 106.

By separately arranging the push rod 114 and the bottle body 101, it is convenient for transportation and storage. Internal threads are provided on the inner wall of the connecting platform 107. A sealing ring 108 is provided at the top of the outer ring surface of the piston 106. The sealing ring 108 is used to increase the sealing performance when pushing the piston 106. Anti-slip vertical lines 109 are equidistantly arranged at the bottom of the outer ring surface of the piston 106. When the push rod 114 is installed on the connecting platform 107 through the thread, the piston 106 will rotate. The vertically arranged anti-slip vertical lines 109 can prevent the piston 106 from rotating;

[0030] Reference Figure 4 , a baffle 110 is connected to the inner wall of the bottle body 101. The baffle 110 plays a role in blocking the partition plate 103. When the medicament at the bottom has not completely entered the top medicine chamber 102, the baffle 110 will keep the partition plate 103 in a fixed position until all the medicament enters the top medicine chamber 102. The baffle 110 is located at the top of the partition plate 103.

[0031] Specifically, the piston 106 and the partition plate 103 are made of rubber. Rubber has a certain deformation ability. When the partition plate 103 and the piston 106 move upward, they can cross the baffle 110 through the deformation of the rubber and continue to move upward. The valve plate 105 is made of silica gel.

[0032] Specifically, reference Figure 1 , an upper bottle stopper 111 is sleeved on the top of the bottle body 101. The upper bottle stopper 111 and the lower bottle stopper 112 play a protective role to extend the effectiveness of the medicament. A lower bottle stopper 112 is sleeved on the bottom of the bottle body 101.

[0033] Specifically, the top medicine chamber 102 is also filled with a protective gas to protect the medicament at the top, thereby ensuring the quality and stability of the medicine.

[0034] An injection assembly, reference Figure 3 and Figure 4, including a needle 113 and a push rod 114. The needle 113 is installed on the needle seat of the bottle body 101. One end of the outer wall of the push rod 114 is provided with an external thread, and the push rod 114 can be connected to the connecting platform 107 through the thread. The push rod 114 is installed on the connecting platform 107 through the external thread.

[0035] In this embodiment, after opening the upper stopper 111 and the lower stopper 112 on the upper and lower sides of the bottle body 101, the push rod 114 can be connected to the bottle body 101. When connecting, the push rod 114 is installed together with the connecting platform 107 by rotation. Then, the push rod 114 is pushed upward. At this time, the medicine chamber 102 at the bottom is compressed, and the internal liquid medicine will move upward, and then be mixed with the medicine at the top. The protective gas in the upper medicine chamber 102 will be discharged until the piston 106 contacts the partition plate 103. When the partition plate 103 and the piston 106 contact and continue to move upward, there will be a sense of blockage in the push rod 114 to remind the injection personnel that the two kinds of medicines are mixed. After discharging the medicine in the bottle body 101, injection can be carried out;

[0036] In another embodiment, a medicine chamber 102 is provided in the bottle body 101. A kind of liquid medicine is stored in the medicine chamber 102. A plurality of separate thin partition plates 103 are provided in the medicine chamber 102. Corresponding stop edges 110 are also provided on the inner wall of the bottle body 101 for dividing the medicine chamber 102 into a plurality of chambers storing liquid medicine. The chambers are arranged at equal intervals, and a fixed amount of medicine is stored in each chamber. When injecting, the liquid medicine space at the bottom is compressed first, and the internal liquid medicine moves upward. At the same time, the liquid medicine at the top will also move upward, so as to be injected into the patient's body. When the piston 106 contacts the bottommost partition plate 103, it indicates that a fixed amount of liquid medicine has been injected. In this way, the function of accurately controlling the injection amount can be achieved, and there will be a change in pressure at the finger when pressing and pushing, which is convenient for judging the injection amount of the medicine according to the resistance when pushing;
