Description

Technical Field

[0001] The utility model relates to the technical field of aseptic covers for infusion bags, in particular to an aseptic combined cover for a medicine infusion bag. Background Art

[0002] During the infusion process of the infusion bottle, air needs to be continuously introduced into the solution through the ventilation tube to generate pressure. Dust and microorganisms (such as bacteria and fungi) in the air can enter the glass bottle and cause contamination of the infusion. Therefore, soft infusion bags are usually used for infusion. During the infusion process, the infusion bag becomes flat and there is no need to inhale air, thereby preventing contamination. However, the sealing cover of the general infusion bag is only sealed with a rubber stopper. Repeated puncture of the rubber stopper when injecting the drug inside is likely to cause chipping in the bottle. In addition, repeated puncture can easily lead to a decrease in the sealing performance of the rubber stopper, making the bottle easily contaminated. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The utility model provides a sterile combined cover for a drug infusion bag, comprising an infusion bag nozzle 1, a sealing cover 2 being sleeved on the top end of the infusion bag nozzle 1, a protective pattern being provided on the inner wall of the infusion bag nozzle 1, which improves the stability of the sleeve connection between the sealing cover 2 and the infusion bag nozzle 1, a sealing ring 3 being provided on the inner side of the sealing cover 2, a rotating slot 16 being provided on the outer wall of the sealing ring 3 and located near the top, a connecting ring 4 being installed on the bottom end of the sealing ring 3, a positioning slot 5 being provided on the outer wall of the sealing ring 3 and located near the top, a positioning block 7 being movably connected to the internal part of the positioning slot 5, and the positioning block 7 being provided on the inner wall of the outer cover shell 6 and located near the bottom, The outer cover shell 6 is clamped on the outside of the positioning slot 5 through the positioning block 7. The top of the positioning block 7 is sleeved with a top cover body 8. The top inner wall of the outer cover shell 6 is installed with a sealing cover 9. The top of the sealing cover 9 is provided with an insertion notch 10. The inner wall of the sealing ring 3 is installed with a sealing plug 11. The top of the sealing plug 11 is provided with an upper injection notch 12 at the left side, and the bottom of the sealing plug 11 is provided with a lower injection notch 13 at a position opposite to the upper injection notch 12. The top of the sealing plug 11 is provided with an upper infusion notch 14 at the right side, and the bottom of the sealing plug 11 is provided with a lower infusion notch 15 below the upper infusion notch 14.

[0021] Furthermore, the outer wall of the bottom end of the connecting ring 4 is tapered, which facilitates the insertion of the connecting ring 4 into the interior of the sealing cover 2. The diameter of the inner wall near the bottom of the sealing cover 2 is smaller than the diameter of the inner wall near the top. After the connecting ring 4 is inserted into the interior of the sealing cover 2, the sealing cover 2 is squeezed outward so that the sealing cover 2 fully fits the connecting ring 4 and the infusion bag tube mouth 1, thereby improving the sealing performance.

[0022] Furthermore, a threaded ring is provided on the outer wall of the connecting ring 4 , and a matching threaded groove is provided at the contact position between the sealing cover 2 and the connecting ring 4 . The connecting ring 4 is inserted into the interior of the sealing cover 2 by rotating the connecting ring 4 .

[0023] Furthermore, a notch is provided on the outer wall of the outer cover shell 6. When the infusion bag needs to be opened, the notch of the outer cover shell 6 is rotated to a position facing the rotating slot 16, and then a special wrench is used to clamp it to the outside of the two rotating slots 16, and then the sealing ring 3 and the connecting ring 4 are rotated through the rotating slots 16 to remove the sealing ring 3 and the connecting ring 4.

[0024] Furthermore, there are three upper injection notches 12, and the three upper injection notches 12 and one upper infusion notch 14 are distributed in a circular array on the top of the sealing plug 11. By setting multiple upper injection notches 12, different positions can be punctured when adding medicine to prevent chipping, and repeated punctures can be prevented from causing the notch to become larger and causing leakage, thereby preventing contamination and improving safety of use.

[0025] Furthermore, a layer of cotton pad is installed at the bottom of the sealing cover 9, so that the sealing cover 9 can wipe the top of the sealing plug 11 when it rotates. After injecting a drug, the outer cover shell 6 is rotated to drive the sealing cover 9 to rotate, and the sealing cover 9 drives the insertion notch 10 to rotate. The insertion notch 10 moves over the upper injection notch 12, and the top of the upper injection notch 12 is sealed by the sealing cover 9, thereby further improving the sealing effect, preventing leakage, and preventing air from entering the inside of the infusion bag through the gap generated after puncture, further improving the safety of use.

[0026] When in use, open the top cover 8 to release the seal on the top of the outer cover shell 6, and then rotate the blocking cover 9, which drives the insertion notch 10 to rotate so that the insertion notch 10 is aligned with the upper injection notch 12, and then align the needle of the syringe after aspirating the medicine with the upper injection notch 12 through the sealing plug 11, and the needle passes through the sealing plug 11 and extends into the bottle through the lower injection notch 13. After the injection is completed, pull out the needle and rotate the blocking cover 9 to dislocate the insertion notch 10 from the upper injection notch 12. The top of the gap 12 is sealed to prevent air from entering the bottle through the interpenetrating gap. When continuing to inject other drugs, the blocking cover 9 is controlled to rotate so that the interpenetrating gap 10 is rotated to the upper injection gap 12 at other positions for subsequent drug addition. After the drug addition is completed, the blocking cover 9 is rotated so that the interpenetrating gap 10 is opposite to the upper infusion gap 14, and then the infusion tube plug is inserted through the sealing plug 11 through the upper infusion gap 14, and the plug passes through the lower infusion gap 15 and extends into the infusion bag, and then the infusion bag is hung upside down for infusion.
