Abstract
The utility model relates to a skin pricking needle which is in a thin sheet shape and is composed of a needle head, a needle body and a needle end, wherein a V-shaped drug storing groove and two parallel grooves with reinforced toughness are pressed on the needle body; the depth of the needle which penetrates into the skin can be controlled by making use of the different width of the widest part of the needle head and the needle body and the fixed length of the needle head. The skin pricking needle has the advantages of simple manufacturing technology, low cost, convenient, accurate and safe operation, less skin injury and convenient clinical use.
Description
This utility model belongs to uses utensil on the clinical medicine, especially a kind of perverse pin of point that is used for tuerculoderma.
Tuerculoderma has been widely used in allergy and other subjects, and in order to understand the situation of body to allergenic reaction and immunologic function, the method for tuerculoderma is a lot, and intradermal test wherein is the most general.And the means that this test is adopted are intradermal injection and put perverse two kinds, prove that through clinical use intradermal injection is because of its complicated operation, and the injected dose degree of accuracy is poor, and the defective that patient's misery is bigger closely and is gradually replaced by the perverse method of point.At present abroad widespread usage put perverse method and carry out skin test because this novel skin test method is at the early-stage in China, so do not produce the perverse pin of regular dedicated points so far as yet.At present manyly wait and operate with different succedaneums such as syringe needle, stud, needle, clinical manipulation is very irregular, influences the actual effect of its method.
The purpose of this utility model is exactly that design is a kind of scientific and reasonable and be suitable for the perverse pin of skin points of clinical tuerculoderma special use, thereby the diagnostic means of tuerculoderma is pushed forward, and makes it more science and is convenient to clinical use.
This utility model is made up of the perverse syringe needle of point, needle body, backshank three parts, wherein is suppressed with a V-type drug storage groove, two parallel toughness grooves that add on the needle body, and backshank has a circular hole.
Accompanying drawing 1 is this utility model outside drawing, wherein: (1) syringe needle (2) needle body (3) V-type groove (4) strengthening groove
Accompanying drawing 2 is this utility model plane graphs.
Embodiment of the present utility model is to realize like this.Adopting thickness is that 0.16 ± 0.01mm aluminum alloy flake is pressed into, front end at needle body (2) has a syringe needle (1) triangular in shape, and its length is 0.5-1.0mm, and the widest part is 0.1-1.0mm, needle tip 0.009-0.015mm, syringe needle the widest part and needle body width do not wait.Needle body (2) length is 37mm, be suppressed with V-type groove (3) and strengthening groove (4) on it, the degree of depth and the width of its groove are 0.5mm, the V-type groove is positioned at the needle body front end and near needle section, strengthening groove (4) spacing with it is 5mm, strengthening groove is two parallel slots, and its spacing is 2-2.5mm for 1.5mm length, and Circularhole diameter is 1.8mm.
The needle length of this utility model design and sharp degree be fixed and syringe needle the widest part different with the width of needle body, penetrate into the degree of depth of skin with the control pin, penetrate into Intradermal and do not cause bleeding again to reach to satisfy, the V-type groove is in order to store small amount of drug (the drug storage amount reaches diagnosis dosage), set position is to satisfy administration simultaneously when pin penetrates into Intradermal, two parallel slots of being suppressed play the effect of booster injection toughness, the circular hole of needle body is easy to sterilization, the usefulness of collection, this is put perverse pin and also can take antigen liquid to be dropped on the skin earlier to go perverse (without a drug storage troughed belt medicine) according to the needs of user again, and this pin also can be done disposable use.
Advantage part of the present utility model is: this is put, and perverse pin manufacture craft is simple, and cost is low, easy to operate, accurate, safety, and skin injury is few, and it is few to enter intracutaneous antigen, does not cause cross-infection, and outward appearance is neat, is convenient to clinical use.
