As described above, in the dispensing method of the medical and health institution, a nurse uses an empty needle, selects the size of the empty needle according to the amount of the liquid medicine to be used, and then draws out the liquid medicine and puts the liquid medicine into the liquid medicine to be used. When the liquid medicine is 50 ML, 100ML or more, the workload of nurses is increased; in addition, in the process of repeatedly pumping the liquid medicine, if the manipulation is incorrect, the liquid medicine is easily polluted, and adverse results are easily brought to patients. Therefore, the utility model provides a sterile bidirectional exhaustible medicine dispensing device; the invention will now be further described with reference to the drawings and specific examples.

Referring to fig. 1 and 2, there is illustrated a sterile, bi-directional ventable dispensing device, comprising, in essence: a first infusion tube bottle inserting needle 1, a first air filter 2, an infusion tube 3, a second infusion tube bottle inserting needle 4 and a second air filter 5; wherein:

the first infusion tube bottle inserting needle 1 and the second infusion tube bottle inserting needle 4 are both made of hard plastics so as to provide enough puncture force. The upper end of the bottle inserting needle 1 of the first infusion tube and the upper end of the bottle inserting needle 4 of the second infusion tube are both provided with a needle point part, and the needle point part is provided with an opening so as to facilitate the entering and exiting of the liquid medicine.

First air cleaner 2, second air cleaner 5 are transfer line air cleaner, just first air cleaner 2 connects on the lateral wall of the lower part of first transfer line bottle inserting needle 1, second air cleaner 5 connects on the lateral wall of the lower part of second transfer line bottle inserting needle 4. The air filter has the main functions of ensuring the balance of air pressure in the infusion tube and outside, avoiding the vacuum formed in the tube from obstructing infusion, and simultaneously, the filter can also remove impurities such as particles in the air entering the infusion tube, thereby preventing the liquid medicine from being polluted. The infusion tube bottle inserting needle with the air filter is widely applied to disposable infusion tubes for infusion of patients at present, and the first infusion tube bottle inserting needle 1 and the second infusion tube bottle inserting needle 4 in the embodiment can be directly made of commercially available products

The two ends of the infusion tube 3 are respectively connected with the lower end of the first infusion tube bottle inserting needle 1 and the lower end of the second infusion tube bottle inserting needle 4, so that the first infusion tube bottle inserting needle 1 is communicated with the second infusion tube bottle inserting needle 2, the liquid medicine is transferred between the liquid supply container 8 and the liquid collection container 9, and the medicine dispensing is realized.

Further, in another embodiment, the infusion tube 3 is a transparent flexible plastic tube, so that the infusion tube can be conveniently bent and the flowing condition of the liquid medicine in the infusion tube can be observed.

Further, in another embodiment, referring to fig. 2, the infusion apparatus further comprises two sets of bottle inserting needle point needle shields 6 made of plastic material, which are respectively used for covering the first infusion tube bottle inserting needle 1 and the second infusion tube bottle inserting needle 4.

Further, in another embodiment, referring to fig. 3, a perfusion tube flow regulator 7 is further included, which is disposed on the perfusion tube 3 to facilitate controlling the flow rate of the liquid in the perfusion tube.

Referring to fig. 3, when dispensing, the first infusion tube bottle inserting needle 1 is inserted into the liquid supply container 8 from the bottle stopper of the liquid supply container 8, the second infusion tube bottle inserting needle 4 is inserted into the liquid receiving container 9 from the bottle stopper of the liquid receiving container 9, and the infusion tube flow regulator 7 is opened, the liquid supply container 8 and the liquid receiving container 9 can be communicated through the sterile bidirectional exhaustible dispensing device in the above embodiment.

Then the liquid supply container 8 is placed above the liquid receiving container 9 (the arm is lifted or the infusion support is adopted for hanging, and the like), liquid medicine in the liquid supply container 8 is transferred into the liquid receiving container 9 for culture under the action of self gravity, after the transfer is finished, the infusion tube flow regulator 7 is closed, the liquid medicine is pulled out from the liquid supply container 8 and then inserted into a new liquid supply container, and the infusion tube flow regulator 7 is opened to continue dispensing until the whole dispensing process is finished. The advantage of this kind of transfer mode is that only need change the confession liquid container of different liquid medicines, then insert the transfer line bottle needle to the confession liquid container of change and can continue to dispense, and the process of dispensing is convenient and fast, and the pollution probability is little, has effectively reduced nurse's work load, has improved work efficiency.

Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
