Pre-encapsulating glass syringe vacuum plugging method

Abstract

The invention discloses a pre-encapsulating glass syringe vacuum plugging method which comprises the following steps of: (1) loading a liquid product tool plate into a box; (2) tool positioning: clamping a part of edge of a glass syringe tool plate in a stage of positioning clamp trough of a positioning tool plate; (3) rubber plug charging tool plate positioning: placing a rubber plug tool plate filled with rubber plugs on the upper part of the glass syringe tool plate, and clamping a part of edge of the rubber plug tool plate in the other stage of positioning clamp trough of the positioning tool plate; (4) closing a door of the box body; (5) pumping with vacuum to eliminate liquid medicine bubbles; (6) releasing pressure and charging plugs; and (7) encapsulating. According to the pre-encapsulating glass syringe vacuum plugging method, air in the lower part of the liquid medicine in a glass syringe can all be exhausted to avoid the overflowing of the liquid medicine, and the lower edge of the rubber plug connected with a push rod in the a syringe is just contacted with the upper surface of the liquid medicine, so that when the glass syringe is used, after a packing is opened and a syringe needle is loaded, the syringe can be directly used by pushing the push rod, and the pre-encapsulating glass syringe vacuum plugging method has the advantages of time saving, working efficiency improvement, use safety improvement of the liquid medicine and is suitable for long-distance transport and long-time storage.

Description

technical field [0001] The invention relates to an auxiliary method for medical equipment, in particular to a vacuum stoppering method for a pre-filled glass syringe. Background technique [0002] The development of syringes has experienced all-glass syringes and disposable plastic syringes, and the connection between the needle cone and the needle is completed by a metal or plastic needle seat. This type of syringe cannot store medicinal liquid for a long time, so when in use, it is necessary to fill the liquid with the medicine and inject it. At present, most of the liquid medicines pass through other packaging media, and then transferred for use. The transfer of liquid medicines will inevitably lead to waste of residual liquid, especially for expensive medicines and biological medicines with a small amount of one-time use. This problem is more prominent, which seriously increases the use of liquid medicines. On the other hand, there are serious problems in the destructio...

AI Technical Summary

Problems solved by technology

[0005] Although the above patent application discloses a glass syringe capable of pre-filling the drug solution, it does not disclose how the drug solution is pre-filled, and according to the applicant’s market research, the pre-filled drug solution will appear at the front of the syringe to form an air gap. When in use, the gas is discharged by pushing the push rod, and the following problems will occur. First, in order to ensure that all the gas is discharged, a part of the liquid medicine must be discharged. Because the amount of liquid medicine is very small, it is difficult to control, and most of the liquid medicine The price is expensive, and the waste is serious; the second is that the existence of gas will pollute the liquid medicine, cause the liquid medicine to fail, and cause harm to the user's body

[0006] On the other hand, there is also the use of pushing the liquid forward through the push rod to discharge the air when pre-filling the liquid medicine. This method also exists. In order to ensure that all the gas is discharged, part of the liquid medicine must be discharged. Less, difficult to master, and most of the liquid medicine is expensive, the waste must be serious
