A kind of skin test needle and its application methodTechnical field
The invention belongs to medical instruments, and in particular to a kind of skin test needle and its application method.
Background technique
Clinically with skin test needle patient forearm lower part intracutaneous test liquid, formed skin mound with judge patient whether medicineObject allergy.It is about 127mm that current skin test needle, which is usually with the injector length of 1ml specification, and wherein needle length is 16mm, needleSharp inclined-plane is 1.5mm.On clinical procedure and specialized teaching material, it is required between syringe needle and epidermis penetrate in 5 ° of subscripts, it is tangible realPatient can ache very much when receiving skin test injection in the operation of border, and especially children's endurance is low, once pain will tamper, be easy needleHead slides, bending leads to skin test injection failure, it has to inject again, patient comfort is poor, is also extremely to consume for doctorWhen effort.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of skin test needle and its application method, it can reduce patient pain,Improve skin test success rate.The technical solution adopted by the invention is as follows:
A kind of skin test needle, including needle tubing and syringe needle further include being placed on the supracutaneous bracket of patient forearm, the needle tubing or syringe needleFor slant setting in bracket so that needle angle is 12 ~ 14 °, the needle angle is axis and patient forearm's epidermis side where needle tubingBetween angle.
Above-mentioned skin test needle, the needle angle are 13 °.
Above-mentioned skin test needle, the length of needlepoint of the syringe needle are 0.7 ~ 1m, and the pinpoint inclined plane of the syringe needle is 0.4 ~ 0.6m, instituteThe total length for stating needle tubing and syringe needle is 70 ~ 90mm.
The total length of above-mentioned skin test needle, the needle tubing and syringe needle is 80mm.
Above-mentioned skin test needle, the needle tubing are placed on bracket, and the needle tubing is used for equipped at least one and support assortedSeveral marker tapes to identify needle angle.
The distance between needle point top of above-mentioned skin test needle, the bracket and syringe needle is 17mm.
A kind of application method of above-mentioned skin test needle, comprising the following steps:
S1) the inhalation test liquid in needle tubing；
S2) skin test area is sterilized, syringe needle is directed at skin test area；
S3 it) places a stent within patient forearm's epidermis and is supported at the marker tape of needle tubing, acupuncture treatment immediately behind the inclination angle of needle tubing is kept to infuseIt penetrates.
In above-mentioned steps S3, when acupuncture treatment is injected, axis where needle tubing and patient forearm's epidermis side are in 12 ~ 14 ° of angles.
The invention has the benefit that 5 ° of traditional inserting needles are changed to 13 ° of angle inserting needles, while reducing the length of syringe needle needle tubingDegree operates, upper hand is simple, greatly mitigates it is ensured that being injected into accurate position completes qualified skin test test convenient for doctorThe pain of patient, hence it is evident that improve the skin test success rate of child patient.

Fig. 3 is the support schematic diagram of the embodiment of the present invention.
In figure: 1 being needle tubing, 2 be syringe needle, 3 be bracket, 11 be marker tape.
Specific embodiment
The present embodiment is a kind of skin test needle, including needle tubing 1 and syringe needle 2, it is characterised in that: further includes being placed on patient forearmSupracutaneous bracket 3, the needle tubing 1 or 2 slant setting of syringe needle in bracket 3 so that needle angle be 12 ~ 14 °, the inserting needle angleSpend the angle between 1 place axis of needle tubing and patient forearm's epidermis side.The needle angle is preferably 13 °,
The length of needlepoint of the syringe needle 2 is 0.7 ~ 1m, preferably 0.7mm, and the pinpoint inclined plane of the syringe needle 2 is 0.4 ~ 0.6m, excellentIt is selected as 0.5mm；The total length of the needle tubing 1 and syringe needle 2 is 70 ~ 90mm, preferably 80mm.
The needle tubing 1 is placed on bracket 3, and the needle tubing 1 is equipped at least one several mark for being used to cooperate with bracket 3Band 11 is to identify needle angle.
The distance between the bracket 31 and the needle point top of syringe needle 2 are 17mm.
A kind of application method of such as above-mentioned skin test needle, it is characterised in that the following steps are included:
S1) the inhalation test liquid in needle tubing 1；
S2) skin test area is sterilized, syringe needle 2 is directed at skin test area；
S3 bracket 3) is placed on patient forearm's epidermis and is supported at the marker tape 11 of needle tubing 1, is pricked immediately after keeping the inclination angle of needle tubing 1Needle injection, guarantees 1 place axis of needle tubing and patient forearm's epidermis side is in 12 ~ 14 ° of angles
It is to want inserting needle within 5 degree on nursing textbook, then the purpose of inserting needle is to generate skin within epidermis to be entered within 5 degreeMound.According to clinical experience, 5 degree of inserting needle patients can ache very much, and adult can also bear, and children's majority can not all be endured, if infusingLimbs twisting is excessive when penetrating just easily causes skin test to fail.Inventor has attempted above-mentioned skin test needle and its inserting needle side thusMethod.
Illustrate the using effect of this skin test needle of the application and its application method below with reference to specific clinical example:
Embodiment one
The present embodiment above-mentioned skin test needle and application method carry out penicillin skin test note to 50 20 years old or more adult patientsIt penetrates.Wherein this 50 patients disposably generate qualified skin mound, are described according to patient, wherein there is 24 patients almost painlessSense, 22 patients have slight pain, and 2 patient's pains obviously but when doing skin test than are in the past keenly felt light.Also, there are 42Patient is shown as skin test feminine gender, the subsequent respective normal medication process of tracking, without any allergic symptom.
Embodiment two
The present embodiment above-mentioned skin test needle and application method carry out penicillin skin test to 30 five years old to 12 years old child patientsInjection.Wherein there are 29 to generate patient in this 30 patients and disposably generates qualified skin mound.Other 1 qualified without generatingThe patient of skin mound carries out second of repetition skin test to it after half an hour, generate qualified skin mound.
According to reaction, wherein there are 14 patients almost without pain, there are 10 slight pains of patient's description, there are 6There is slight performance of struggling in discontented eight years old patient.
Comparative example
The existing 1ml skin test needle of this comparative example, traditionally 5 ° of inserting needle modes as defined in teaching material inject 50 patients, wherein46 have obvious pain, 4 have slight pain.
In summary, the skin test needle of the application can be more convenient to use, and realize special angle inserting needle, mitigate patient pain and protectSkin mound is demonstrate,proved to generate.
