Embodiment 1

[0038] Such as figure 1 , figure 2 As shown, an applicator hypodermic indwelling needle in this embodiment at least includes a main housing 10 , a puncture mechanism 40 and an indwelling mechanism 50 . Wherein the two ends of main housing 10 are all open structures, and under the unactivated state, the upper end opening of main housing 10 is closed by sealing sticker 30, and the edge of this sealing sticker 30 has the easy to tear off sealing sticker with hand Flange 31 ; the lower end of the main housing 10 is open with a cover 20 , and the edge of the cover 20 is also provided with a convex portion 21 to facilitate the separation of the cover and the main housing.

[0039] Such as Figure 11-13 As shown, the indwelling mechanism 50 of this embodiment is connected to the main housing 10 through the puncture mechanism when the indwelling mechanism 50 is not activated. After activation, the adhesive part 5204 of the indwelling mechanism is pasted together with the patient's ...

Embodiment 2

[0065] The difference between this embodiment and the first embodiment is that the structure of the indwelling mechanism 50 is different. Such as Figure 12B As shown, in this embodiment, the indwelling steel needle 54 is directly fixedly connected to the indwelling seat 51 , and the indwelling steel needle and the indwelling soft needle are communicated through a one-way valve 518 as a one-way liquid flow device.

Abstract

The invention relates to the technical field of infusion, and concretely relates to an application type subcutaneous indwelling needle, which at least comprises an indwelling mechanism, the indwellingmechanism at least comprises an indwelling seat; wherein an infusion connector is arranged at the upper end of the indwelling seat, an indwelling steel needle is arranged in the center of an infusionconnector, a bonding part is arranged on the lower end face of the indwelling seat, an indwelling soft needle protruding out of the bonding part is further arranged at the lower end of the indwellingseat, the indwelling soft needle and the indwelling steel needle are coaxially arranged, and a one-way liquid flow device is arranged between the indwelling steel needle and the indwelling soft needle. In the structure, the indwelling steel needle and the indwelling soft needle are simultaneously arranged in the indwelling mechanism; wherein part of the indwelling soft needle is located under theskin, and the indwelling steel needle is located in the infusion connector, so that the steel needle of an injector does not need to be used any more during injection, only the connecting end of theinjector without a needle head or an insulin infusion pump needs to be connected with the infusion connector, and the technical advantages of being convenient to use and wide in application range areachieved.

Description

technical field [0001] The invention relates to the field of transfusion technology, in particular to an application type hypodermic indwelling needle. Background technique [0002] The use of indwelling needles can reduce the pain caused by repeated punctures, usually including intravenous indwelling needles and subcutaneous indwelling needles. Especially for diabetics, who need regular subcutaneous injections of insulin, the use of indwelling needles is even more necessary. The existing indwelling needles used by diabetic patients usually only have soft needles, and they also need to be used with steel needles of insulin syringes. There are strict restrictions on the size and length of steel needles. Poor; the steel needle is for one-time use, the use cost is high, and the economy is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the technical defects of inconvenient use and high cost of the indwelling n...
