Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

An infusion set cap, as shown in fig. 1 to 7, comprises an inner cap 1 and an outer cap 2, the outer cap 2 is detachably mounted on the inner cap 1, and the outer cap 2 covers the outer of the inner cap 1. Specifically, the method comprises the following steps:

the outer cover 2 comprises an outer cover body 21 and a transfusion hole 22 arranged on the outer cover body 21, and the transfusion hole 22 is plugged by a turning handle 23; wherein a cavity for accommodating the inner cap 1 is provided in the outer cap body 21. The inner cap 1 comprises an inner cap body 11 and a flange 12 which is radially protruded on the outer wall of the inner cap body 11, and the flange 12 is used for being connected with an infusion bag to increase the contact surface between the inner cap 1 and the infusion bag and further increase the sealing property between the inner cap body and the infusion bag. The inner cap body 11 is axially provided with a through liquid hole 13, and is connected with an infusion bag and the outside through the infusion hole 13. The upper opening of the inner cover body 11 is provided with a sealing sheet 14, and the sealing sheet 14 is used for sealing the liquid through hole 13 so as to ensure that the liquid medicine in the infusion bag does not flow out. A pull ring 15 is arranged on the sealing piece 14, and the sealing piece 14 is conveniently separated from the inner cap body 11 through the pull ring 15 so as to open the liquid through hole 13.

In one embodiment, as shown in FIGS. 1-7, infusion port 22 projects axially inwardly with guide tube 24 for guiding the infusion needle. Preferably, the guide tube 16 is of unitary construction with the cover body 21. When the infusion device is used, an infusion needle is inserted into an infusion bag through an infusion hole 22, and the infusion needle are sealed through tight fit between the infusion hole 22 and the infusion needle. It can be seen that, through the setting of stand pipe 24, can increase the contact surface between stand pipe 24 and the transfusion needle, and then improve the leakproofness between transfusion needle and enclosing cover 2.

In one embodiment, as shown in fig. 1 to 7, the first sealing ring 25 is provided to protrude downward from the inner top of the outer cap body 21, and the second sealing ring 16 is provided to protrude upward from the top of the inner cap body 11; after the inner cap 1 and the outer cap 2 are combined, the first sealing ring 25 is hermetically connected with the second sealing ring 16. In the present embodiment, the first seal ring 25 is located within the second seal ring 16; i.e. the outer wall of the first sealing ring 25 abuts against the inner wall of the second sealing ring 16 to achieve a seal between the inner cap 1 and the outer cap 2.

In the above embodiment, the first seal ring 25 is a tight fit with the second seal ring 16, as shown in fig. 1-7.

In the above embodiment, as shown in fig. 1 to 7, in order to facilitate and reliably combine the first seal ring 25 with the second seal ring 16, the lower end of the outer wall of the first seal ring 25 and the upper end of the inner wall of the second seal ring 16 are chamfered.

In one embodiment, as shown in fig. 1 to 7, the outer wall of the inner cap 2 is provided with external threads 26, and the inner wall of the outer cap 1 is provided with internal threads 17 that mate with the external threads 26. The inner cap 1 and the outer cap 2 can be assembled quickly through the structure.

In one embodiment, as shown in fig. 1-7, the sealing panel 14 is integral with the inner cap body 11, and the easy-tear notch 18 is provided at the junction of the sealing panel 14 and the inner cap body 11. That is, the portion of the easy-tear groove 18 is thinner than the other portions, and when the sealing sheet 14 is torn by the pull ring 15, the sealing sheet 14 can be easily separated from the inner cap body 11 by being guided by the easy-tear groove 18.

When the utility model is used, as shown in figures 1-7, after a medical staff takes medicines and infusion bags, the outer cover 2 is rotated and opened in the sterile dispensing room, and the sealing sheet 14 is torn off through the pull ring 15 to open the liquid through hole 13. Then medical personnel can put the medicine into the infusion bag through the liquid through hole 13, then cover the enclosing cover 2, through reversing the infusion bag to promote the liquid medicine to mix with the normal saline in the bag, accomplish and dispense. Then, the medical staff only needs to pull the turning handle 23 to open the infusion hole 22 and insert the infusion needle to complete the preparation before infusion.

The above are merely preferred embodiments of the present invention, and are not intended to limit the scope of the utility model; the utility model is intended to cover by the appended claims, modifications and equivalents, which may fall within the true spirit and scope of the utility model.
