Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to a safe type anti-drop transfusion system, as shown in figure 1, it includes infusion pipeline 7, the both ends of infusion pipeline 7 are put through with needleless infusion joint 9 and infusion bag pjncture needle 4 respectively, infusion pipeline 7 is gone up and is equipped with precision filtering net 8 along needleless infusion joint 9 to infusion bag pjncture needle 4's direction in proper order, dropping speed regulator 6, ink fei shi burette 5, the outside of infusion bag pjncture needle 4 and the lower extreme fixed connection of the back screwed pipe 2 that can stretch, the upper end of the back screwed pipe 2 that can stretch and the lower extreme fixed connection of transfusion system screwed socket 3 that can stretch.

As shown in figures 1 and 2, the upper end of the thread port 3 of the infusion set is sleeved with an infusion set puncture needle protective sleeve 10.

As shown in fig. 4 and 5, when the stretchable and retractable threaded tube 2 is in a stretched state, the head end of the infusion bag puncture needle 4 is arranged in the infusion set threaded port 3; when the stretchable and retractable threaded pipe 2 is in a retracted state, the head end of the infusion bag puncture needle 4 passes over the upper port of the infusion set threaded port 3.

The working principle of the utility model is as follows:

the threaded-port infusion bag 1 can be tightly connected with the threaded port 3 of the infusion apparatus, so that the infusion leather strips are prevented from falling off from the bottle stopper of the threaded-port infusion bag 1.

The stretchable and retractable threaded tube 2 can be stretched and retracted as required. When in a packaging state, the stretchable and retractable threaded pipe 2 is stretched to enable the puncture needle 4 of the infusion bag to retract in the threaded port 3 of the infusion apparatus; when in use, the stretchable and retractable threaded pipe 2 is compressed to enable the puncture needle 4 of the infusion bag to protrude out of the threaded port 3 of the infusion apparatus, penetrate into the bottle stopper and drain the liquid medicine. After the infusion, the threaded infusion bag 1 and the infusion apparatus of the utility model stretch and retract the threaded pipe 2 before separating, so that the infusion bag puncture needle 4 retracts in the threaded port 3 of the infusion apparatus, the threaded port 3 of the infusion apparatus is rotated again, the infusion apparatus is taken down, and the occurrence of needle-prick injury can be effectively avoided. In the infusion process, if the infusion apparatus is pulled, the infusion apparatus can be passively stretched through the stretchable and retractable threaded pipe 2 to serve as a buffer, but the infusion apparatus cannot fall off, and only the puncture needle 4 of the infusion bag needs to be inserted into the bottle stopper again.

As shown in fig. 3, the application method of the present invention is as follows:

1. checking the infusion apparatus according to the standard flow of venous infusion, and confirming that the infusion apparatus meets the use requirement.

2. And (3) opening the package of the infusion apparatus at the bottle stopper of the sterile threaded-port infusion bag 1.

3. Taking down the puncture needle protective sleeve 10 of the infusion apparatus, and aligning the threaded port 3 of the infusion apparatus with the threaded port infusion bag 1 for rotary butt joint and fixation.

4. The stretchable and retractable threaded pipe 2 is held by hand and pushed towards the direction of the threaded infusion bag 1, the infusion bag puncture needle 4 is pushed by force to puncture the bottle stopper on the threaded infusion bag 1, and the front end of the stretchable and retractable threaded pipe enters the threaded infusion bag 1.

5. Air in the transfusion device is emptied, and the needleless transfusion connector 9 is connected with a transfusion needle.

6. The dripping speed regulator 6 is opened, and the transfusion is started after the dripping speed is regulated.

7. After the infusion is finished, the stretchable and retractable threaded pipe 2 is held by hand, and the infusion bag puncture needle 4 is pulled out in the opposite direction of the threaded-port infusion bag 1, so that the infusion bag puncture needle 4 retracts into the infusion apparatus threaded pipe 3.

8. And reversely rotating and taking down the threaded pipe 3 of the infusion apparatus from the threaded-port infusion bag 1.

9. The transfusion device is destroyed and then is recycled and treated in a centralized way according to the medical waste treatment process.
