Technical Field
[0001] The utility model relates to the technical field of syringes, in particular to a syringe core support. Background Art
[0002] At present, when using a syringe to inject a liquid medicine, since the dosage of the liquid medicine injection does not require the entire liquid medicine to be injected every time, the remaining liquid medicine needs to be refrigerated after one injection to maintain the efficacy and performance of the liquid medicine. Usually, the liquid medicine and the syringe are placed in a cold storage room for refrigeration so that the medicine can be directly injected when it is used again. However, it is found in actual use that during the refrigeration period, the storage method easily causes condensation inside the syringe, and the water vapor in the cold storage room easily penetrates and diffuses into the syringe, causing the metal parts or electronic components of the syringe to rust, thereby reducing the service life of the syringe due to component damage.
[0003] The existing patent CN20212294835.2 discloses a detachable liquid medicine holder assembly, which is applied to an electronic injection pen, including an injection pen control device and a detachable liquid medicine holder assembly. The detachable liquid medicine holder assembly includes a pen cap and a refill holder. The pen cap is installed at the front end of the injection pen control device, and the refill holder is installed in the pen cap. A refill is arranged in the refill holder, and the refill is fixedly connected in the refill holder. The refill holder is fixedly connected in the pen cap. The function is to remove the detachable liquid medicine holder assembly from the injection pen control device, and then put it in a cold storage room for refrigeration to prevent water vapor from entering the control device and damaging the electronic components, which effectively increases the service life of the electronic injection pen.
