Abstract
A disposable skin test device is composed of a needle and a needle tube with a hollow cylinder containing the scale for indicating the volume of skin test liquid, and features that the volume indicated by the position of scale is measured from the needle point, so the liquid medicine is actually sucked up when preparing skin test liquid and the liquid medicine is theoretically needed.
Description
This utility model relates in hypodermic mode introduces intravital technique with the apparatus field with medium, more particularly relates to the skin anaphylactic test device that uses in a kind of clinical medicine.
Do drug sensitivity test in the clinical medicine now, do not have special-purpose skin tester, syringe needle replaces but connect upward with 1 milliliter of syringe.Since syringe calibrated starting at a little be initial position at needle tubing, thereby in use there is a dead space, the capacity that is pin stalk, pin post and nipple inner chamber is not comprised by the numerical value that scale is represented, thereby makes the numerical value of the concentration of the solution for skin test that is mixed with greater than theory provision.Through experiment, the dead space amount is 0.045ml.With the penicillin is example, and the compound concentration of its solution for skin test of national regulation is the 200-500 units per ml, because the dead space influence, actual compound concentration is the 534-1087 units per ml.According to clinical investigation, because the solution for skin test concentration that is made into the 1ml syringe is big, make part patient skin test result present false positive, causing can not be with this Drug therapy disease.
Thereby the purpose of this utility model provides the skin anaphylactic test device that a kind of accurately preparing solution for skin test concentration can correctly be judged the skin test result.
This utility model and existing disposable syringe structure proximate, it also comprises syringe needle and needle tubing two parts, has the scale of expression capacity on the empty tube of needle tubing part, its construction features is that the represented capacity in scale position is counted from needle point.
Because capacity is to count from needle point shown in this utility model, the content of nipple inner chamber that has comprised pin stalk, pintle and the needle tubing of syringe needle, thereby when preparing solution for skin test, the actual amount of liquid medicine that extracts equals the amount of liquid medicine of theoretical defined, thereby has overcome the false-positive problem of skin test result that causes greatly owing to solution for skin test concentration.
Accompanying drawing has provided concrete structure of the present utility model, wherein:
Fig. 1 is a longitudinal section wherein; Fig. 2 is its outline drawing.
Among the figure: 1 is empty tube, and 2 is core bar, and 3 is piston head, and 4 is nipple, and 5 is pintle, and 6 are the pin stalk, and 7 is pinhead sleeve, and 8 is scale.
This utility model is disposable use, and except that pin stalk (6) and piston head (3), all the other are made by medical plastic.Also can remove pintle (5), and pin stalk (6) rear end directly is fixed in the nipple (4).Empty tube capacity is consistent with 1 milliliter of syringe.Quovis modo, reality " O " point of scale (8) is the needle point place, promptly the shown capacity that goes out of scale (8) is counted from needle point.
Claims (2)
1, a kind of disposable use skin tester comprises syringe needle and needle tubing two parts, has the scale (8) of expression capacity on the empty tube (1) of needle tubing part, and it is characterized in that: the represented capacity in scale position is to begin from needle point.
2, disposable use skin tester according to claim 1 is characterized in that the pin stalk (6) of syringe needle part directly is fixed in the nipple (4) of needle tubing part.
