Description
Technical field
This utility model belongs to medical apparatus and instruments, specifically is a kind of spininess vent needle syringe, and international monopoly Main classification number plan is Int.Cl.A61M 5/00 (2006.01) I.
Background technology
Oral drugs mainly absorb by digestive system, enter blood after blood circulation is delivered to whole body, reach therapeutic effect.Generally speaking, after the human body oral drugs, liver and kidney can exclude most dose usually, and drug effect or curative effect are descended, and cause the wasting of resources on the other hand.Therefore, people's utility model the subcutaneous injection of medicine.Reach the identical curative effect of subcutaneous injection, oral dose must be equivalent to be several times as much as the required dose of subcutaneous injection.Moreover, some drugs such as insulin, vaccine etc., oral way can not effectively be absorbed, and for these medicines, adopting subcutaneous injection is a kind of inevitable choice.Yet patient, particularly old man and child dislike effectively this and subcutaneous injection mode efficiently because of pain usually.So, a kind of painless new medicine subcutaneous injection utensil and mode are provided, be a kind of raising drug effect, save medicine resource and care patient's meaningful work.
The utility model content
At the deficiencies in the prior art, the technical problem that this utility model quasi-solution is determined is that a kind of spininess vent needle syringe is provided.This syringe construction is simple, injects painless, safe in utilization, personal convenient, with low cost.
The technical scheme that this utility model solves described needle technology problem is: design a kind of spininess vent needle syringe, it is characterized in that this syringe forms by syringe needle and flexible container are equipped, described flexible container is a hemispherical; Described syringe needle is a disc, is evenly distributed with the taper micropin on it, and the whole height of syringe needle is 500-600 μ m, and the height of micropin is 200-250 μ m, and the pinhole diameter of micropin is 30-45 μ m, and the needle point of micropin is the inclined-plane; The maximal density of described micropin is 5/mm
2, the centre-to-centre spacing between the micropin is not less than 600 μ m.
Compared with prior art, spininess vent needle syringe of the present utility model has following advantage:
1. the micropin that One's name is legion is arranged on the syringe needle, is evenly distributed (constituting the spininess hole), and the height of micropin and diameter design science can be realized painless or the hypodynia subcutaneous injection, help injection for curing;
2. syringe construction is simple, and volume is little, and cost is low, and is easy to use, safe.

Fig. 4 is the micropin 3 d shape structure sketch map of a kind of embodiment of this utility model spininess vent needle syringe.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof:
The spininess vent needle syringe of this utility model design (being called for short syringe, referring to Fig. 1-4) is characterized in that this syringe by syringe needle 2 and flexible container 1 equipped forming, and described flexible container 1 is a hemispherical; Described syringe needle 2 is a disc, the whole height of syringe needle 2 (or thickness) is 500-600 μ m, be evenly distributed with taper micropin 3 on the syringe needle 2, the skin of considering the human body different piece is with different with the thickness of fat, the height of micropin 3 is designed to 200-250 μ m, the pinhole diameter of micropin 3 is 30-45 μ m, preferred 30 μ m; And the needle point of micropin 3 is the inclined-plane; The maximal density of described micropin 3 is 5/mm
2, the centre-to-centre spacing between the micropin 3 is not less than 600 μ m.
The further feature of this utility model syringe is the plane that the tip end of micropin 3 has 4-6 μ m.Such design makes the needle point of micropin 3 can be too not sharp, and intensity improves, and is not easy to fracture.
The material of this utility model syringe needle 2 is a monocrystal silicon, can go out the pin hole of micropin or the passage of pin liquid by its anisotropic etching; The profile of micropin 3 is taper, and the isotropic etching of employing material goes out the tapered profile of micropin.This utility model micropin 3 processing methods own are same as prior art.
The hemispherical flexible container 1 of this utility model adopts PDMS (Polydimethylsiloxane is called for short silicone rubber) material preparation, and technology of preparing itself also is a prior art.
In the confined space of medicine filling between hemispherical flexible container 1 and syringe needle 2 that the product design of this utility model syringe holder needs, constitute the pastille disposable micro-syringe that is not easy to be subjected to ambient temperature and humidity effect.This syringe of this utility model is because product itself contains the required medicine of injection for curing, and it is convenient especially therefore to use, and does not need specific professional training.This utility model syringe is not subjected at flexible container 1 under the situation of external force effect, and medicine can not flow out by the pin hole of micropin 3 or overflow automatically.When using this injector to inject, only need with the hemispherical flexible container 1 of thumb applying light, pressure will make micropin 3 thrust in the human body skin, and with medicine inject subcutaneous in, and only thrust subcutaneous appropriate depth (20-120 μ m), can not touch peripheral nerve, thereby human body can feels pain, and medicine will be organized the interstitial fluid dissolving, then diffusion, absorbed by the blood capillary of skin corium at last, reach ideal therapeutic effect.Another characteristics of this utility model syringe are to be applicable to that the people who was not subjected to medical training implements self-injection in very easy mode, and are very convenient, and painless.
This utility model is not addressed part and is applicable to prior art.
Provide specific embodiment of the utility model below, further specifying this utility model, but it does not constitute the restriction to this utility model claim.
The preparation insulin syringe.
187 micropins 3 of uniform design on the silicon chip that a diameter is 10mm, its density is 5/mm
2, the distance between the micropin 3 is 600 μ m; The whole height of syringe needle 2 is 500 μ m, the height 200 μ m of micropin 3 on it, and the internal diameter of micropin 3 and external diameter are respectively 30 μ m and 40 μ m, the wall thickness of micropin 3 is 5 μ m, at the needle point 40 μ m place bevels of distance micropin 3, the tip end of micropin 3 has the plane of 5 μ m, to improve the intensity of needle point.Hemispherical flexible container 1 adopts the PDMS material preparation, and diameter dimension is 10mm.
According to the treatment requirement, loaded the medicine insulin after, adopt bonding techniques described hemispherical flexible container 11 and described syringe needle 2 airtight being bonded together, be prepared into the spininess vent needle syringe that contains appropriate amount of drug.
