Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 2 to 7, the bionic disposable silicone infusion needle with adhesive comprises a needle head 10, a silicone tube 20, a fixing tube 30 communicating the needle head 10 and the silicone tube 20, and a connector 80 disposed at one end of the silicone tube 20 far from the fixing tube 30. In fact, the structure of the self-adhesive bionic disposable silicone infusion needle of the present embodiment is different from the existing disposable silicone infusion needle shown in fig. 1 in that the needle handle 70 is not disposed on the fixed tube 30, and instead, the first layer of bionic fins 50, the second layer of bionic fins 60 and the sleeve 40 are disposed.

Specifically, as shown in fig. 2, the bionic disposable silicone infusion needle with adhesive of the present embodiment includes a first layer of bionic fins 50, a second layer of bionic fins 60, and a sleeve 40.

As shown in fig. 3 and 4, the first layer of bionic fin 50 includes a silica gel sheet 51, a non-drying adhesive layer 52 disposed on a lower end surface of the silica gel sheet 51, and a tearable waterproof film layer 53 disposed on an end surface of the non-drying adhesive layer 52 opposite to the silica gel sheet 51. The waterproof film layer 53 can be provided with a sectional line or divided into two parts at the center of the lower end face of the silica gel sheet 51 so as to be convenient for tearing the waterproof film layer 53 from the center of the lower end face of the first layer of bionic fin 50 to two sides respectively, and the structure is similar to that of a tearable protective film of the existing band-aid.

The sleeve 40 is coaxially sleeved on the fixed tube 30, and the sleeve 40 is arranged in the center of the upper end face of the silica gel sheet 51 of the first layer of bionic fin 50.

The sleeve 40 is fixed on the fixed tube 30, and the first layer of bionic fins 50 and the second layer of bionic fins 60 are fixed on the sleeve 40, so that the sleeve 40, the first layer of bionic fins 50, the second layer of bionic fins 60 and the fixed tube 30 form an integral structure.

In one embodiment, the silica gel sheet 51 of the first layer of bionic fin 50 is of a whole soft silica gel structure, so that when the bionic fin is adhered to the skin, the adhering effect is good, the flatness is good, and bubbles are not easy to generate.

The second layer of bionic fins 60 comprise bionic bodies 61 and bionic half fins 62 symmetrically arranged on two sides of the bionic bodies 61, the bionic bodies 61 are arranged at the upper ends of the sleeves 40, the bionic half fins 62 are arranged above the first layer of bionic fins 50, and the length direction of the bionic bodies 61 is parallel to the long axis direction of the sleeves 40.

In one embodiment, the bionic body 61 is internally provided with a cavity structure. The bionic body 61 is of a thin-wall structure, and the bionic body 61 is a rubber bag with a cavity structure arranged inside. The rubber bag is in an elliptic cylinder shape.

In one embodiment, the biomimetic half-fin 62 comprises a plastic film layer. Therefore, the bionic fin 60 on the second layer is light in weight and easy to form, and different shapes can be designed and manufactured.

In one embodiment, as shown in fig. 5, the lower end surface of the bionic half-fin 62 is provided with ribs 63, and the ribs 63 are connected with the bionic body 61.

The ribs 63 may be provided in plural, for example, three ribs 63 are provided on each bionic half-fin 62 in the present embodiment. The ribs 63 are preferably rubber or silicone strips. The bionic half-fin 62 is supported and reinforced, so that the collapse of the bionic half-fin is avoided, and the stereoscopic impression can be enhanced.

In order to ensure that the first layer of bionic fins 50 and the second layer of bionic fins 60 are in accordance with the stereoscopic impression, the plane where the bionic half fins 62 are located and the parallel plane where the first layer of bionic fins 50 are located are intersected in space and form an acute angle.

The thickness of the first layer of bionic fin 50 is less than 5mm, and the thickness of the bionic half fin 62 is less than 2 mm. Of course, the thickness of the first layer of biomimetic fins 50 and biomimetic half-fins 62 may also be other values.

In one embodiment, the first layer of biomimetic fins 50 and the second layer of biomimetic fins 60 are both butterfly-shaped. Of course, the first layer bionic fin 50 and the second layer bionic fin 60 can be in other shapes, animal shapes or cartoon character shapes. For example, it may be a bird, a bee, etc.

As shown in fig. 6, before puncturing, the first layer of bionic fins 50 and the second layer of bionic fins 60 are folded upwards, fingers can pinch the two sides of the folded first layer of bionic fins 50, and the first layer of bionic fins 50 are regarded as handles, so that puncturing operation can be directly performed at this time. After the puncture is completed, the waterproof film layer 53 on the first bionic fin 50 is torn while the first bionic fin 50 is loosened to expose the non-drying adhesive layer 52, and the silica gel sheet 51 of the first bionic fin 50 can be adhered to the skin of the puncture part by using the non-drying adhesive layer 52, as shown in fig. 7. Since the silicone sheet 51 is fixed to the sleeve 40, after the silicone sheet 51 is adhered and fixed, the sleeve 40 is fixed, so that the fixing tube 30 fixed to the sleeve 40 is effectively fixed, and the needle 10 is fixed. Compare in the fixed mode of traditional adhesive tape, the mode that silica gel piece 51 pasted fixedly through not dry glue film 52 is not only fixed effectual, and the comfort level is high moreover, and more has the interest, and especially adapted children patient uses.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that a person skilled in the art should also recognize that several modifications and decorations can be made without departing from the principle of the present invention, and the protection scope of the present invention is also covered.
