Embodiment
Referring to FIG. 1, present embodiments providing a kind of subcutaneous microneedle injection device 100 comprising injection ontology 110, depth
Adjust ring 120, paste attachment 130 and paster 140.
Wherein, referring to Fig. 2, injection ontology 110 includes injection tube 111, injection rod 112 and syringe needle 113.Syringe needle 113
It is distributed in the bottom of injection tube 111 vertically and is connected to the inside of injection tube 111.Injection rod 112 be embedded in injection tube 111 and
It can be slided up and down relative to injection tube 111, so that the medical fluid in injection tube 111 be pushed to be discharged from syringe needle 113.
In the present embodiment, the generally hollow cylindrical shape of injection tube 111 is corresponding, and injection rod 112 is disk-shaped, guarantee
When injection rod 112 slides in injection tube 111, the medical fluid in injection tube 111 can be completely exhausted out.In addition, injection rod 112
Upper surface is flushed with the upper surface of injection tube 111, that is to say, the injection rod 112 in the application is different from conventional syringe
The structure of the stretching injection tube 111 of injection rod 112.It is flushed by being arranged the upper surface of injection rod 112 with injection tube 111, it can
The overall volume of subcutaneous microneedle injection device 100 is reduced to a greater extent, while when in use, benefit presses with finger injection rod 112
So that injection rod 112 moves in injection tube 111, thus by injecting liquid drug to subcutaneous tissue.To guarantee injection rod 112 opposite
It keeps sealing during injection tube 111 slides, in the present embodiment, opens up seal groove 117 in the outside of injection rod 112, and
Sealing ring 118 is set in seal groove 117 to guarantee leakproofness.
The subcutaneous microneedle injection device 100 can when leaving the factory in advance pour into medical fluid in injection tube 111, can also provide
Empty injection tube 111, applies needle personnel and injects medical fluid into injection tube 111 as needed.Specifically, it in the present embodiment, is infusing
Penetrate and offer medical fluid import 115 and the sealing-plug 116 for sealing the medical fluid import 115 on bar 112, medical fluid import 115 with
Injection tube 111 is connected to.In the present embodiment, sealing-plug 116 is silica gel material, with good leakproofness, while by medical fluid
When injecting in injection tube 111, directly it is inserted into sealing-plug 116 using the syringe needle 113 of existing injection needle, medical fluid is injected
Afterwards, injection needle is extracted, since silica gel is soft and has elasticity, not only can be good at sealing medical fluid import 115,
It can also continue to keep sealing according to its elasticity after extracting injection needle simultaneously, so that the leakproofness of injection tube 111 is maintained,
Internal medical fluid is not easily susceptible to pollute, much cleaner.
In the present embodiment, the length of syringe needle 113 is 2.5-8mm, and syringe needle 113 used in the present embodiment is capillary syringe needle,
Its model 28-32G.Length is shorter, and syringe needle 113 is thinner, and injection area is bigger for single syringe needle 113 compared to before, injection
Liquid is small to organizational stress, and feeling of pain is with regard to small.In the present embodiment, the number of syringe needle 113 be it is multiple, such as 2-5, it is preferable that this
The number of syringe needle 113 is three in embodiment, and three syringe needles 113 are uniformly distributed along the bottom disc of injection tube 111, can
Guarantee that liquid is uniform out, injection area is big, and small to organizational stress, feeling of pain mitigates.
Fig. 1, Fig. 3 and Fig. 4 are please referred to, depth adjustment ring 120 is ring-type, is sheathed on the outside of injection tube 111, is infused
Shooting cylinder 111 and depth adjustment ring 120 are slidably connected to adjust the length that syringe needle 113 is stretched out from depth adjustment ring 120, depth adjustment
The setting of ring 120 enables to the syringe needle 113 when subcutaneous microneedle injection device 100 is not used, connected on injection tube 111 can
It is blocked completely by depth adjustment ring 120, to avoid bringing fear to infant during applying needle.Meanwhile the depth tune
Section ring 120 can also slide inside it according to injection tube 111 and adjust the length that syringe needle 113 stretches out depth adjustment ring 120, should
Length that is to say that syringe needle 113 penetrates the depth of patient skin, thus insertion depth needed for the injection position different according to patient
It is adjusted.
Injection tube 111 can take various ways, such as sliding slot sliding rail, rotation to slide relative to the sliding of depth adjustment ring 120
Dynamic or clearance fit is simultaneously supported using elastic construction.Specific in the present embodiment, it is provided at the top of depth adjustment ring 120
Elastic component 121, the top of injection tube 111 are provided with the supporting table 114 outwardly protruded along 111 radial direction of injection tube, support
Platform 114 is connected on the top of elastic component 121.It is outwardly protruded by supporting table 114, thus the outer ring with depth adjustment ring 120
It flushes or at least part is corresponding, depth adjustment ring 120 and supporting table 114 connect, and make its syringe needle needing to adjust injection tube 111
When 113 stretching depth adjustment ring 120, injection tube 111 can be squeezed, the supporting table 114 of injection tube 111 moves downward, to squeeze
Compression elasticity part 121, elastic component 121, which generates deformation, enables injection tube 111 to move in depth adjustment ring 120.
Referring to Fig. 1, the elastic component 121 in the present embodiment includes the first elastic piece 122 and the second elastic piece 123, this reality
Apply in example, the first elastic piece 122 at least two, and be arranged along the circumferential direction of depth adjustment ring 120, the second elastic piece 123 with
The connection of each first elastic piece 122.Specifically, the first elastic piece 122 is arc and Open Side Down, the second elastic piece 123 tool
Have with the first elastic piece 122 backwards to the curved portion 124 being arranged and the horizontal part 125 for connecting curved portion 124, that is to say, curved portion
