Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-4 The utility model provides an embodiment: a syringe for preventing broken bottle plugs from entering, comprising a syringe body 1, an isolation mechanism 2 is clamped on the outer surface of the other side of the syringe body 1, and a drug injection mechanism 3 is slidably arranged inside one side of the syringe body 1.

[0034] The medicine can be stored or injected through the syringe body 1, and the medicine injection mechanism 3 can be used to extract or inject the medicine in the medicine bottle, which is convenient for medical staff to mix and prepare different amounts of medicine according to the needs of different patients. The stopper at the front end of the medicine bottle can be punctured through the isolation mechanism 2, and then the punctured stopper can be collected to avoid breaking into the syringe body 1, causing the syringe body 1 to be blocked and unable to be used, or the stopper entering the liquid to affect the use of the medicine.

[0035] Reference Figure 1-3 The syringe body 1 includes an empty barrel 101, a connecting block 103 is fixedly arranged in the middle of the other side of the empty barrel 101, a through hole 107 is opened at the front end of the connecting block 103, elastic blocks 106 are fixedly arranged at the upper and lower ends of one side of the empty barrel 101, a connector 104 is threadedly arranged inside the connecting block 103, a needle 105 is fixedly arranged on the other side of the connector 104, and a protrusion 102 is fixedly arranged at the upper and lower ends of one side of the empty barrel 101.

[0036] The empty cylinder 101 can be used to temporarily store the medicine, and the connecting head 104 and the syringe body 1 can be threadedly connected through the connecting block 103, so that the connecting head 104 can be disassembled and replaced later. The position of the piston rod 301 can be fixed by the elastic block 106. At the same time, when used in conjunction with the connecting plate 302 in the middle of the piston rod 301, it can be prevented that the medical staff's hand strength is too large, causing the piston rod 301 to move too fast, and the medicine leakage or excessive use causes waste of resources. The needle 105 and the syringe body 1 can be connected for use through the connecting head 104. The needle 105 facilitates the injection and mixing of the medicine, and the protrusion 102 facilitates the medical staff to hand-hold the syringe body 1 for injection.

[0037] Reference Figure 4 The isolation mechanism 2 includes a fixed shell 201, a fastener 206 is fixedly provided at the front end inside the fixed shell 201, a pull rod 207 is slidably provided inside the fastener 206, a fixed rod 208 is fixedly provided on the other side of the pull rod 207, an insertion rod 202 is fixedly provided on the other side of the fixed shell 201, a slide groove 203 is provided at the upper and lower ends of the insertion rod 202, a baffle 205 is fixedly provided inside the insertion rod 202, and a limit block 204 is fixedly provided at the upper and lower ends of the baffle 205.

[0038] The insertion rod 202 can be fixed by the fixing shell 201, and the isolation mechanism 2 can also be clamped and fixed. The clamping piece 206 is convenient for medical staff to quickly install or remove the isolation mechanism 2. The position of the fixing rod 208 can be changed by the pull rod 207. The isolation mechanism 2 can be conveniently clamped and fixed in conjunction with the fixing rod 208, which is convenient for medical staff to quickly install or remove the isolation mechanism 2 in the later stage. The plug at the front end of the medicine bottle can be punctured by the insertion rod 202, and the broken plugs can be collected. The slide groove 203 is convenient for adjusting the position of the baffle 205 in the later stage. The fragments of the cork are collected by the baffle 205 to prevent the fragments of the cork from entering the needle 105 and causing blockage in the syringe body 1. The baffle 205 can be fixed by the limit block 204.

[0039] Reference Figure 2-3 The drug injection mechanism 3 includes a piston rod 301, a sealing ring 303 is fixedly arranged on the other side of the piston rod 301, and a plurality of connecting plates 302 are fixedly arranged at equal intervals in the middle of the piston rod 301.

[0040] The position of the sealing ring 303 can be adjusted and fixed through the piston rod 301, which is convenient for extracting or injecting the medicine at a later time. The sealing ring 303 can seal the inside of the syringe body 1 to prevent liquid or gas leakage. The connecting plate 302 is convenient for medical staff to pull the piston rod 301 outward at a later time.

[0041] Working principle: insert the injection mechanism 3 into one side of the syringe body 1, then slide the piston rod 301 to the bottom of the syringe body 1 to completely discharge the internal gas, and then snap-fit ​​and fix the isolation mechanism 2 to the other side of the syringe body 1, so that the isolation mechanism 2 is fixed to the outer surface of the connector 104, which protects the connector 104, and then adjust the angle of the medicine bottle, insert the isolation mechanism 2 on the other side of the syringe body 1 into the bottle stopper of the medicine bottle, and collect the broken bottle stopper fragments, which can prevent the broken bottle stopper fragments from entering the syringe body 1 and causing internal blockage and unusability, or entering the medicine and affecting its use, and then pull the pull rod 207 outward, adjust the position of the fixing rod 208, and then pull the isolation mechanism 2 to the other side of the syringe body 1 to remove the isolation mechanism 2, and then insert the needle 105 on the other side of the connector 104 into the bottle stopper through hole 107, and then pull the piston rod 301 to one side to extract the medicine.
