Detailed Description

The utility model will now be described in further detail with reference to the following detailed description and with reference to the accompanying drawings, it being emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the utility model and its application.

The embodiment provides a transfusion harbor adhesive film, as shown in fig. 1-3, comprising an adhesive film body 1, wherein the adhesive film body 1 can be in a square or round structure, the embodiment is preferably in a rectangular structure, the bottom of the adhesive film body 1 is provided with an adhesive layer and a liner layer 3, the bottom of the adhesive layer is provided with at least two release papers 2, in order to facilitate tearing of the release papers 2, one side of the release papers 2 is preferably provided with a stent 21, and the adhesive layer is the same as the adhesive used in the traditional medical adhesive film; the cushion layer 3 is located at the position of the film body 1 near the center, so as to increase the stability of the film fixation, the cushion layer 3 is used for separating the needle wing 4 of the infusion port from the skin of the patient, so as to avoid the occurrence of pressure sore phenomenon caused by direct contact between the needle wing 4 and the skin of the patient, the size of the cushion layer 3 corresponds to the size of the needle wing 4 of the remaining needle, meanwhile, the cushion layer 3 comprises two groups of cushion layers 3, the two groups of cushion layers 3 are arranged side by side and the outer side 31 thereof is respectively adhered to the bottom of the film body 1, in the embodiment, the outer side 31 of the cushion layer 3 refers to the other side of the opposite sides of the two groups of cushion layers 3, and the design mode is such that the two groups of cushion layers 3 form a butterfly wing structure, so that the cushion layer 3 is conveniently placed under the needle wing 4 in use; the thickness of the backing layer 3 is 0.8-1.2cm, preferably 1cm, and in this embodiment, it is verified that the backing layer 3 with the thickness can avoid the influence of the subcutaneous position of the opposite retaining needle, and the backing layer 3 with the thickness can form a certain strength tension on the needle wing 4 part of the retaining needle in cooperation with the film pasting part provided with the adhesive layer, and the tension can press the retaining needle and the needle wing 4 part so as to fix the retaining needle and the needle wing 4.

The application principle of the embodiment comprises the following steps: when the retention needle is fixed: firstly, the cushion layer 3 is placed below the needle wing 4 of the retention needle, then the retention needle is continuously pressed by one hand, the release paper 2 is separated from the viscose layer by the other hand, then the viscose layer of the adhesive film is pushed away to be pasted on the skin of a patient so as to fix the opposite retention needle, as shown in fig. 4, by adopting the steps, the adhesive film part provided with the viscose layer and the cushion layer 3 with a certain thickness can be mutually matched so as to form a certain strength tension on the needle wing 4 part of the retention needle, and the tension of the strength can press the retention needle and the needle wing 4 part so as to fix the retention needle and the needle wing 4; when the film is torn off: the nurse presses the needle wing 4 of the retention needle with one hand and separates the film body 1 positioned at the periphery of the retention needle from the skin of the patient with the other hand.

It can be seen that this pad pasting of this embodiment adopts the pad layer 3 to keep apart patient's skin and infusion port needle wing 4 part when using, avoids needle wing 4 to cause the emergence of pressure sore phenomenon to patient's skin, in addition, this pad pasting of this embodiment infusion port's needle wing 4 is not glued by the viscose layer when using, but adopts the tension opposition that forms between pad layer 3 and pad pasting body 1 of a certain thickness to stay the needle to oppress, so not only be convenient for tear the pad pasting, and can not appear in tearing the pad pasting operation because of its difficult and needle wing 4 separation and bring the problem of uncomfortable sense for the patient, that is, this pad pasting of this embodiment tears the subsides convenience, the travelling comfort is strong, has fine practicality.

As a preferred embodiment of the present utility model, the specific structure of the cushion layer 3 corresponding in size to the dimensions of the retention needle wings 4 comprises:

the size of the lining layer 3 is equal to the size of the needle wing 4 of the retention needle;

or, the outer peripheral dimension of the cushion layer 3 is larger than the dimension of the needle-retaining wings 4 by 0.3 cm to 05cm, preferably, the outer peripheral dimension of the cushion layer 3 is larger than the dimension of the needle-retaining wings 4 by 05cm, so that the cushion function can be better realized.

As a preferred embodiment of the present utility model, the cushion layer 3 is a laminated butterfly wing structure, and the material constituting the cushion layer 3 comprises a sterile gauze or a sterile sponge; the purpose of providing the cushion layer 3 in a laminated shape is to facilitate the operator (medical staff) to choose the number of layers for laying the cushion layer 3 under the needle wings 4 of the indwelling needle according to the actual situation of the patient, for example, when the hand of the patient is thin and slender, the cushion layer 3 needs to be laid under the needle wings 4 in order to meet the tension requirement, and when the hand of the patient is more round and fat, a part of the cushion layer 3 can be laid under the needle wings 4.

As a preferred embodiment of the present utility model, in order to facilitate observation of the position of the wings 4, the film body 1 provided with the position of the cushion layer 3 is preferably provided in a transparent structure.
