Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical preparation technology, specifically to a pharmaceutical preparation container with anti-pollution function. Background Technology
[0002] Clinically, a large number of medications need to be prepared daily. Some medications are extremely difficult to dissolve, requiring repeated aspiration and insertion / removal during the preparation process. This not only increases the workload of nurses but also easily leads to contamination of the medication solution. The process of drawing the solution, injecting it into the vial, and then drawing it out again is not a closed loop and is highly susceptible to contamination. Furthermore, during the aspiration process, the inner wall of the syringe is easily contaminated, as is the syringe plunger, which in turn contaminates the medication solution inside the syringe, affecting the safety of the medication preparation. Utility Model Content

[0008] As a preferred technical solution of this utility model, the opening of the dispensing injection cylinder is provided with a guide cover, and the guide cover is provided with a guide hole for the push rod to pass through.
[0009] As a preferred technical solution of this utility model, the guide cover is provided with a vent hole.
[0010] As a preferred embodiment of this utility model, the outer wall of the opening end of the dispensing syringe is provided with a limiting ring.
[0011] As a preferred embodiment of this utility model, the outer wall of the injection connector of the dispensing syringe is provided with a tube connector, the end of the tube connector is connected to a flexible tube, and the end of the flexible tube is connected to a needle.
[0012] As a preferred embodiment of this utility model, the injection connector is connected to the pipe connector via a multi-port connector.
[0013] As a preferred embodiment of this utility model, the multi-port connector includes a sleeve connector connected to the injection connector, one end of the sleeve connector is connected to a dispensing cylinder, the outer wall of the dispensing cylinder is connected to two dispensing branch pipes, and the dispensing branch pipes are connected to the pipe connector.
[0014] As a preferred technical solution of this utility model, the liquid separator is provided with a liquid guide tube that communicates with the sleeve joint inside. The side wall of the liquid guide tube is provided with a liquid guide port. The end of the liquid guide tube is provided with a rotating shaft that passes through the liquid separator. The rotating shaft is connected to the liquid separator via a sealed bearing. The outer end of the rotating shaft is provided with a wheel.
[0015] The beneficial effects of this utility model are:

When the push rod is pushed, the push rod and piston are always inside the anti-contamination sleeve. The sliding seal provides a good seal, preventing the push rod and piston from coming into contact with the outside air, which would contaminate the inside of the drug preparation injection cylinder and thus contaminate the prepared drug solution, thereby improving the safety of drug preparation.
[0017] 2. This anti-pollution drug preparation container allows for easy extraction by rotating a wheel, which in turn rotates a rotating shaft, causing the liquid guide tube to rotate so that the liquid guide port on the liquid guide tube is positioned at one of the dispensing branches on the dispensing tube. Similarly, during injection, the rotating shaft rotates the liquid guide tube so that the liquid guide port on the liquid guide tube is positioned at another dispensing branch on the dispensing tube, allowing for injection. This avoids contamination caused by repeated insertion and removal. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example 1: As Figure 1 and Figure 2 As shown, this utility model discloses a drug preparation container with anti-pollution function, including a drug preparation injection cylinder 1. One end of the drug preparation injection cylinder 1 is provided with an injection connector 2, and the other end of the drug preparation injection cylinder 1 is provided with an opening. Inside the drug preparation injection cylinder 1, there is a piston 3. One end of the piston 3 is provided with a push rod 4 extending out of the opening. The outside of the drug preparation injection cylinder 1 is covered by an anti-pollution sleeve 5, which covers the push rod 4. The anti-pollution sleeve 5 is connected to the outer wall of the drug preparation injection cylinder 1 via a sliding seal 6.
[0027] The outer end of the push rod 4 is provided with a connecting plate 7, which is connected to the anti-fouling sleeve 5 by sealant to ensure the sealing of the connection between the connecting plate 7 and the anti-fouling sleeve 5.
[0028] The connecting plate 7 is provided with a connecting rod 8 at its outer end, and a push plate 9 at its outer end, which facilitates pushing the connecting plate 7.
[0029] The opening of the dispensing syringe 1 is provided with a guide cover 10, and the guide cover 10 has a guide hole for the push rod 4 to pass through, which can play a good guiding role for the push rod 4 and improve the stability of the push rod 4 movement.
[0030] The guide cover 10 has a vent hole 11, which can be used for ventilation. When the push rod 4 is pushed, the gas inside the anti-fouling sleeve 5 enters the medicine injection cylinder 1 through the vent hole 11, thus avoiding the push rod 4 from being pushed by pressure.
[0031] The outer wall of the opening end of the drug dispensing syringe 1 is provided with a limiting ring 12, which can prevent the anti-fouling sleeve 5 from being pulled out of the drug dispensing syringe 1.
[0032] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the outer wall of the injection connector 2 of the drug dispensing syringe 1 is provided with a tube connector 13, the end of the tube connector 13 is connected to a flexible tube 14, and the end of the flexible tube 14 is connected to a needle 15, which can be used for extraction or injection.
[0033] The injection connector 2 is connected to the pipe connector 13 via a multi-port connector 16.
[0034] The multi-port connector 16 includes a sleeve connector 17 connected to the injection connector 2. One end of the sleeve connector 17 is connected to a dispensing cylinder 18. The outer wall of the dispensing cylinder 18 is connected to two dispensing branch pipes 19, which are connected to the pipe connector 13. The dispensing cylinder 18 has a liquid guide cylinder 20 connected to the sleeve connector 17 inside. The side wall of the liquid guide cylinder 20 has a liquid guide port 21. The end of the liquid guide cylinder 20 has a rotating shaft 22 that extends out of the dispensing cylinder 18. The rotating shaft 22 is connected to the dispensing cylinder 18 via a sealed bearing. The outer end of the rotating shaft 22 is equipped with a wheel. When extracting, the wheel is rotated, which drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the liquid guide tube 20 to rotate, so that the liquid guide port 21 on the liquid guide tube 20 rotates to a liquid distribution branch tube 19 on the liquid distribution tube 18, and extraction can be performed. When injecting, the rotating shaft 22 drives the liquid guide tube 20 to rotate, so that the liquid guide port 21 on the liquid guide tube 20 rotates to another liquid distribution branch tube 19 on the liquid distribution tube 18, and injection can be performed, avoiding contamination caused by repeated insertion and removal.
[0035] Example 2 is a further improvement on Example 1. The side wall of the multi-port connector 16 is provided with multiple liquid distribution branches 19, which can sequentially extract multiple kinds of medicine liquids.
[0036] During operation, this anti-contamination drug preparation container features a sliding anti-contamination sleeve 5 on the outside of the drug preparation injection cylinder 1. When the push rod 4 is pushed, the push rod 4 and piston 3 remain inside the anti-contamination sleeve 5. The sliding seal 6 provides excellent sealing, preventing the push rod 4 and piston 3 from contacting external air and causing contamination of the drug preparation solution, thus improving drug preparation safety. For extraction, rotating the wheel drives the rotating shaft 22, which in turn rotates the liquid guide cylinder 20, causing the liquid guide port 21 on the liquid guide cylinder 20 to rotate to a dispensing branch pipe 19 on the dispensing cylinder 18, allowing extraction. For injection, rotating the shaft 22 drives the liquid guide cylinder 20 to rotate, causing the liquid guide port 21 on the liquid guide cylinder 20 to rotate to another dispensing branch pipe 19 on the dispensing cylinder 18, allowing injection. This avoids contamination caused by repeated insertion and removal.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
