Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

The embodiment provides a novel medical injector, as shown in fig. 1-4, including cylinder 1 and push rod 2, the front end of push rod 2 stretches into in the cylinder 1, the front end of push rod 2 is equipped with plug 3, the front end of cylinder 1 is equipped with the nipple, install pintle 4 on the nipple, the front end of pintle 4 is connected with syringe needle 5, be equipped with elastic component and paster 6 on syringe needle 5 in proper order, the one end of elastic component with pintle 4 is connected, the other end of elastic component with paster 6 is connected, 6 covers of paster are established on syringe needle 5. When the injection needle 5 on the pintle 4 is inserted into a human body in the injection process, the paster 6 which can slide in the injection needle 5 is tightly adhered to the skin under the pressure of the elastic piece; after the injection is finished, when the injection needle 5 is pulled out of the skin, the elastic piece and the patch 6 are attached to the skin needle hole, so that the subsequent manual pressing operation is reduced.

Specifically, the elastic member includes two elastic plastic sheets 7, and the plastic sheets 7 are thin sheets. The plastic sheets 7 are all in wing shapes, the plastic sheets 7 are symmetrically arranged on two sides of the pintle 4, the inner side of the upper end of the plastic sheet 7 is bonded with the outer wall of the pintle 4, the plastic sheet 7 and the pintle 4 are bonded only by slightly sticking, the adhesive film 10 of the patch 6 can be torn off, and the sticking method is various, for example, point sticking can be selected, and hot melt gluing can also be used. The middle part of the plastic sheet 7 is concave, and the lower end of the plastic sheet 7 is adhered to the upper surfaces of the two sides of the patch 6.

Specifically, the upper surface of plastic sheet 7 is equipped with hair side magic subsides, the lower surface of plastic sheet 7 is equipped with hook face magic subsides.

Further, the lower surface of the patch 6 is provided with a cotton pad 8. The cotton pad 8 is in contact with the needle eye. The patch 6 and the cotton pad 8 are provided with through holes for the injection needle 5 to penetrate out. The upper surface of the patch is provided with a hair surface magic tape. The paster is pasted with the plastic sheet through the magic tape. The plastic sheets can be adhered by magic tapes.

Furthermore, the injection needle further comprises a needle sleeve 9, wherein a sticking film 10 which is stuck with the sticking sheet 6 is arranged in the needle sleeve 9, and a through hole through which the injection needle 5 penetrates out is formed in the sticking film 10. The adhesion of the patch 6 to the film 10 is less than the adhesion of the plastic sheet 7 to the pintle 4. The lower surface of the patch 6 is provided with an adhesive layer, the patch 6 is adhered with a film 10, and the film 10 can be a plastic film. The two ends of the adhesive film 10 are adhered/fixed with the openings of the needle sleeve 9. Optionally, the needle sheath is clamped with the needle cylinder, the inner wall of the needle sheath is provided with a protrusion, the needle cylinder is correspondingly provided with a plurality of toothed rings 11, and the protrusion is clamped with the joint of the adjacent toothed rings. In order to make the patch and the adhesive film easy to separate, two sides of the lower surface of the patch are provided with non-sticky gripping lugs 12, and optionally, release paper is pasted on the two sides of the lower surface of the patch to form the non-sticky gripping lugs. When the sticking film is adhered with the sticking film, the grasping lugs exceed two ends of the sticking film, and when the needle sleeve is pulled out, the grasping lugs are held down towards the needle cylinder by fingers, so that the sticking film and the sticking film can be separated quickly.

The working principle of the utility model is as follows: the needle sleeve 9 is pulled out, and the adhesive force of the adhesive sheet 6 and the adhesive film 10 is smaller than that of the adhesive sheet 7 and the pintle 4, so that the adhesive sheet 6 is separated from the adhesive film 10; when the injection needle 5 on the pintle 4 is inserted into the human body, the patch 6 and the cotton pad 8 are contacted with the skin of the human body, the plastic sheet 7 is deformed to apply a pressure to the patch 6, and the patch 6 is tightly attached to the needle hole of the skin under the action force of the plastic sheet 7 and the skin of the human body. After the injection, the paster 6 and the plastic piece 7 both ends are firmly pressed to the hand, and the pressure of hand is greater than the adhesion of plastic piece 7 and pintle 4, when taking skin out with syringe needle 5, pulls down plastic piece 7 from pintle 4 in the same direction as the area, and plastic piece 7 paster 6 and cotton pad 8 break away from syringe needle 5, and through hair side magic subsides and hook side magic subsides bonding with plastic piece 7, the eye of a needle on the skin then is hugged closely by cotton pad 8, paster 6 and plastic piece 7 and is covered.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the utility model. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
