the bottom end cap opening of the fixing cap 6 of the transfusion port base is matched with the transfusion port base and used for fixing the transfusion port base;

infusion port base locking cap 6 is close to one side of lock needle box 1 and is connected with between the lock needle box 1 folded plate group 7, infusion port base locking cap 6 drives folded plate group 7 and reciprocates, holding tank 8 has been seted up on the face of lock needle box 1 bottom, and folded plate group 7 is the individual layer platelike after folding and accomodates to in the holding tank 8.

Further, folded plate group 7 includes U-shaped board 701 and long board 702, U-shaped board 701 middle part sets up U-shaped groove 703, and U-shaped groove 703 extends to U-shaped board 701 bottom and forms the opening, long board 702 cooperatees with U-shaped groove 703, U-shaped board 701 bottom both ends are connected with the articulated of infusion port base locking cap 6, U-shaped groove 703 tank bottom on U-shaped board 701 is fixed in long board 702 one end, the long board 702 other end is connected with the cell wall of holding tank 8 is articulated.

Furthermore, one end of the holding groove 8 close to the needle of the infusion needle 4 extends to one side wall of the needle locking box 1 to form a notch, and the width of the notch is larger than that of the U-shaped plate 701.

The implementation mode is specifically as follows: when the whole transfusion port needle is stored, the folding sleeve 5 and the transfusion port base fixing cap 6 are pulled down to wrap the needle head, the folding sleeve 5 is in a stretching state at the moment, and the folding plate group 7 is in a fully-opened state;

when the transfusion port needle is used for intravenous injection, the transfusion port base fixing cap 6 is directly clamped on the surface of skin bulged by the transfusion port base, the transfusion port base fixing cap 6 is held by a hand to limit and fix the transfusion port base, then the butterfly wing part 2 is held by the other hand, the needle locking box 1 and the transfusion needle 4 are pressed down, the needle head of the transfusion needle 4 is moved downwards and inserted into the transfusion port fixing seat to carry out injection operation, the U-shaped plate 701 and the long plate 702 of the folding plate group 7 are continuously folded and close to adapt to the needle head which moves downwards continuously, after the injection is finished, the transfusion port base fixing cap 6 is continuously pressed, the butterfly wing part 2 is pulled upwards, after the needle head is sensed to be separated from the transfusion port fixing seat, the needle head is continuously pulled upwards for a distance to sense that the needle head is separated from the skin, at the moment, the whole transfusion port needle can be moved, the needle head is also wrapped by the transfusion port base fixing cap 6 and the folding sleeve 5, the situation that the needle head is shaken to easily hurt the hand part is not generated, see in particular fig. 3;

when the abdominal cavity is filled, the maximum insertion length of the needle head needs to be ensured, after the infusion port needle is taken out, the infusion port base is clamped by the aid of the infusion port base fixing cap 6, then the butterfly wing part 2 is pressed downwards to perform needle inserting work until the needle is inserted into the infusion port base, the needle head needs to be continuously pressed down until the folding sleeve 5 is compressed to be in the thinnest state due to excessive fat of the abdomen during the process, the U-shaped plate 701 and the long plate 702 are folded into a single-layer plate shape and are contained in the containing groove 8, compared with the prior art, the maximum insertion length of the needle head is realized at the moment, the application range is wider, and particularly shown in fig. 4;

fill the completion back, press infusion port base locking cap 6 equally, upwards pull out butterfly alar part 2 and extract the syringe needle, after upwards extracting a section distance, feel the syringe needle and break away from behind the infusion port fixing base, continue to pull up a section distance, it can to feel the syringe needle and break away from skin, need control the syringe needle this moment and do not extract to the folding cover 5 top after the compression, in order to avoid being injured, better can pull out a section distance at the syringe needle after, 5 upwards tensile folding covers, like this after the syringe needle breaks away from the infusion port fixing base, the section distance that continues to pull up has just fine control, use the impression better, easier control.

As shown in fig. 3-4, folding cover 5 sets up to the form of falling frustum of a prism, folding cover 5 is made by the silica gel material, 5 top of folding cover seal set up and bottom opening set up, infusion needle 4 activity runs through 5 tops of folding cover.

Furthermore, a handle 9 is fixedly arranged on one side of the top of the folding sleeve 5.

The implementation mode is specifically as follows: folding cover 5 of this application is the same with folding cup structure principle among the prior art, can realize that thickness is thinnest when folding to can reduce occuping of syringe needle length, stretch more easily through handle 9.

As shown in fig. 2, 6 fixed rubber pads 10 that are equipped with in inner chamber top of infusion port base locking cap, rubber pads 10 middle part is provided with the round hole that is used for through transfusion needle 4, can laminate with skin through setting up of rubber pads 10, and is more comfortable, also increases the stability of whole infusion port base locking cap 6 and infusion port base joint.

As shown in fig. 5, pressing pads 11 are fixedly arranged on two sides of the fixing cap 6 of the port base and the folding plate group 7 in the vertical direction, and the arrangement of the pressing pads 11 can facilitate the hand to press the fixing cap 6 of the port base, so that the operation is more convenient.

As shown in fig. 3-4, two scale marks 12 are arranged on the outer wall of the infusion needle 4 above the folding sleeve 5, and the scale marks 12 are groove bodies or pigment coatings.

The implementation mode is specifically as follows: through the arrangement of the scale marks 12, the indication effect can be achieved after the needle head is pulled out of the skin, the needle head is prevented from completely disengaging from the folding sleeve 5, and the whole infusion port needle is prevented from being taken down without pulling out the skin;

in addition, the number of the scale marks 12 is two, one scale mark 12 is used for prompting that the needle head is pulled out of the skin during intravenous injection, and the other scale mark 12 is used for prompting that the needle head is pulled out of the skin during peritoneal irrigation.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
