Description

Skin test needle

Technical Field

The utility model belongs to a medical tool, in particular to a skin test needle and a use method thereof.

Background

Clinically, a test solution is injected into the lower part of the forearm of a patient by a skin test needle to form a skin dome so as to judge whether the patient is allergic to the drug. Current skin test needles are typically about 127mm in length using a 1ml gauge syringe with a 16mm needle length and a 1.5mm tip bevel. Clinical regulation and professional teaching materials all require that 5 degrees between syringe needle and the epidermis are injected, and it is very painful when the patient receives skin test injection in actual operation in fact, and especially children's tolerance is low, and once painful will be moved, easy syringe needle landing, crooked lead to skin test injection failure, had to inject once more, and patient's comfort level is poor, and it is very consuming time and power also to the doctor.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a skin test needle and application method thereof can alleviate patient's pain, improves the skin test success rate. The utility model adopts the technical scheme as follows:

the skin test needle comprises a needle tube, a needle head and a support placed on the skin of the forearm of a patient, wherein the needle tube or the needle head is obliquely placed on the support so that the needle inserting angle is 12-14 degrees, and the needle inserting angle is an included angle between the axis where the needle tube is located and the skin surface of the forearm of the patient.

In the skin test needle, the needle inserting angle is 13 degrees.

Above-mentioned skin test needle, the needle point length of syringe needle is 0.7~1mm, the needle point inclined plane of syringe needle is 0.4~0.6mm, the total length of needle tubing and syringe needle is 70~90 mm.

In the skin test needle, the total length of the needle tube and the needle head is 80 mm.

According to the skin test needle, the needle tube is placed on the support, and at least one mark belt matched with the support is arranged on the needle tube to mark the needle inserting angle.

In the skin test needle, the distance between the bracket and the top end of the needle point of the needle head is 17 mm.

The use method of the skin test needle comprises the following steps:

s1) sucking the test solution into the needle tube;

s2) disinfecting the skin test area, and aligning the needle head to the skin test area;

s3) placing the bracket on the forearm skin of the patient and supporting the bracket at the mark belt of the needle tube, and keeping the inclination angle of the needle tube and then inserting the needle for injection.

In step S3, during the needle insertion and injection, the axis of the needle tube forms an angle of 12-14 ° with the surface of the forearm of the patient.

The utility model has the advantages that: change traditional 5 into 13 contained angles needle insertions, reduce the length of syringe needle tubing simultaneously, just can guarantee to inject to accurate position and accomplish qualified skin test experiment, the doctor's operation of being convenient for, the first hand is simple, has greatly alleviateed patient's pain, has obviously improved children patient's skin test success rate.

Drawings

Fig. 1 is a schematic view of a usage state of an embodiment of the present invention;

FIG. 2 is a schematic view of a needle cannula according to an embodiment of the present invention;

fig. 3 is a schematic view of a bracket according to an embodiment of the present invention.

In the figure: 1 is a needle tube, 2 is a needle head, 3 is a bracket and 11 is a mark belt.

Detailed Description

The embodiment is a skin test needle, including needle tubing 1 and syringe needle 2, its characterized in that: still including placing support 3 on patient's forearm epidermis, needle tubing 1 or syringe needle 2 slope are placed at support 3 so that the angle of inserting needle is 12~14, the angle of inserting needle is the contained angle between needle tubing 1 place axis and patient's forearm epidermis face. The needle insertion angle is preferably 13,

the needle point length of the needle head 2 is 0.7-1 mm, preferably 0.7mm, and the needle point inclined plane of the needle head 2 is 0.4-0.6 mm, preferably 0.5 mm; the total length of the needle tube 1 and the needle head 2 is 70-90 mm, preferably 80 mm.

The needle tube 1 is placed on the support 3, and at least one plurality of mark belts 11 used for being matched with the support 3 are arranged on the needle tube 1 to mark the needle inserting angle.

The distance between the bracket 31 and the tip of the needle 2 is 17 mm.

A use method of the skin test needle is characterized by comprising the following steps:

s1) sucking the test solution into the needle tube 1;

s2) disinfecting the skin test area, and aligning the needle head 2 to the skin test area;

s3) placing the bracket 3 on the forearm epidermis of the patient and supporting the bracket at the position of the mark belt 11 of the needle tube 1, keeping the inclination angle of the needle tube 1 and then pricking and injecting, ensuring that the axis of the needle tube 1 forms an included angle of 12-14 degrees with the forearm epidermis of the patient

My is a paediatrics nurse, also is two children's mother, and I can select the angle a little bit more deeply when giving child's vein puncture at every turn, has also reduced child's pain when guaranteeing the success rate of puncturing, because see that kind of fear to the pain when child is faced with vein puncture and skin test, really be the heartache of purpose, the misery when wanting to alleviate child's vein puncture and skin test. When a child is subjected to skin test, the child tells me that the skin test done by the child is not painful, so that the pain caused by the skin test is relieved by changing the needle inserting angle in consideration of the skin test, the needle is inserted within 5 degrees on a textbook, the needle is inserted within 5 degrees, the needle is inserted within the epidermis within 5 degrees, the needle is inserted within the epidermis, a skin hill can be formed only when the needle is inserted within the epidermis, so that the needle is inserted within 5 degrees, 15 tests are performed on the left forearm of the child, the needle is inserted from 8 degrees to 15 degrees, the skin test is performed every 0.5 degree, and the skin test is finally found at 12-14 degrees, particularly 13 degrees, and hardly has any pain feeling and has the skin hill. There were next practice classmates and colleagues who voluntarily asked me to test on their forearms, and only one of the ten people said something but not pain.

The following will explain the use effect of the skin test needle and the use method thereof in the present application with reference to specific clinical examples:

example one

This example uses the above described skin test needles and methods of use to perform a skin test injection of penicillin into 50 adult patients over twenty years of age. All 50 of these patients produced a qualified skin dome at once, and according to patient descriptions, 24 of them had almost no pain, 22 had slight pain, and 2 had significant pain but much less pain than when the skin test was performed before. In addition, 42 patients showed negative skin test, followed by normal course of medication without any allergic symptoms.

Example two

This example was performed using the skin test needles and methods of use described above, with 30 children aged five to twelve years old, using a skin test injection of penicillin. Of these 30 patients, 29 patients who produced were eligible for skin dome production at one time. Another 1 patients who did not produce a qualified skin dome were subjected to a second repeat skin test half an hour later, producing a qualified skin dome.

According to the response of the patients, 14 patients had almost no pain, 10 patients described slight pain, and 6 patients under eight years old showed slight struggling performance.

Comparative example

In the comparative example, 50 patients were injected with a conventional 1ml skin test needle in a 5 ° needle insertion manner prescribed in the conventional textbook, 46 of which had a marked pain and 4 of which had a slight pain.

In summary, the skin test needle of this application can more facilitate the use, realizes that specific angle advances the needle, alleviates the painful skin dune of assurance and produces.
