Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a packaging method and device for propofol injection. The packaging method for propofol injection can reduce the waste of propofol caused by adsorption in the storage and transfer process; Repeated aspiration of propofol injection during use reduces the chance of secondary pollution; it is convenient for medical staff to use directly and saves injection time; since this packaging form can achieve zero residual oxygen, it can greatly prolong the life of propofol injection. shelf life

Embodiment 1

[0032] Embodiment 1: A kind of packing method of propofol injection

[0033] A kind of packing method of propofol injection provided by the invention, this packing method comprises the steps:

[0034] a. Liquid medicine filling: inject 50ml of propofol liquid medicine into the syringe 3 with the rubber stopper cap 6 installed through the filling machine;

[0035] b. Deoxygenation: remove the oxygen in the syringe 3 to less than 5% by nitrogen replacement;

[0036] c. Install the piston 4: by vacuuming the syringe 3 to form a negative pressure, the piston 4 is introduced;

[0037] d. Sealed storage of pre-filled syringes: use medical packaging bags to store the filled pre-filled syringes.

[0038] In the above technical solution, the filling machine can quantitatively extract propofol from the liquid medicine storage tank according to the actual demand, and the way of filling the liquid medicine quantitatively by the filling machine is more efficient than medical staff manual...

Embodiment 2

[0047] Embodiment 2: A kind of packaging device of propofol injection

[0048] refer to figure 1 As shown, the prefilled syringe includes a Luer connector 1 , a screw connector 2 , a syringe 3 , a piston 4 and a push rod 5 .

[0049] refer to figure 1 As shown, the piston 4 is wrapped around the top of the push rod 5, and the piston 4 and the push rod 5 are jointly sleeved in the syringe 3. The top of the syringe 3 is provided with a Luer connector 1, and the outside of the Luer connector 1 is The surface is covered with a screw joint 2.

[0050] refer to image 3 with Figure 4 As shown, the inner surface of the screw joint 2 is provided with an internal thread 21, and the rubber plug cap 6 is screwed on the inner surface of the screw joint 2 through the internal thread 21. The well-fitted protective cap structure is more tightly connected, and the product is not easy to loose during sterilization and transportation, thereby ensuring that the drug is not polluted by the ...

Abstract

The invention relates to the technical field of medicine and provides a packing method for propofol injections. The packing method comprises the steps of medicine liquid filling, deoxygenization, piston installation, sealed storage for prefilled syringes and the like. A packing device for the propofol injections comprises a syringe, a piston, a rubber plug protecting cap and a push rod. A Luer connector is arranged at the top end of the syringe. The outer surface of the Luer connector is sleeved with a spiral connector. The rubber plug protecting cap is installed at the top end of the spiral connector. By means of the packing method for the propofol injections, the waste caused by adsorption or transfer in the using process of the propofol injections can be reduced; repeated suction of the propofol injections in the using process is avoided, and the chances of secondary pollution are reduced; the packing device can be used by medical personnel directly and conveniently, and time for clinical application is saved; the storage time of the propofol injections can be prolonged.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a packaging method and device for propofol injection. Background technique [0002] Propofol, whose chemical name is 2,6-diisopropylphenol, is a new type of rapid and short-acting intravenous anesthetic commonly used clinically for induction of anesthesia, maintenance of anesthesia, and sedation of critically ill ICU patients. It has the advantages of fast onset of anesthesia induction, rapid recovery and complete functional recovery, and low incidence of postoperative nausea and vomiting. For a long time, propofol has been packaged in vials or ampoules for injection. When using it, it is drawn into a syringe before injection. When using undiluted propofol injection for direct infusion, it is generally necessary to use a micropump or an infusion pump , in order to control the infusion rate. This method of storing propofol in vials or ampoules first, and then injecting it durin...
