Abstract

A skin test injection syringe, it comprises syringe and syringe needle; Further comprise that needle angle determines lobe, described needle angle determines that lobe top becomes 5 ° of angles with the line of needle tip and the body of syringe needle, and the described needle angle pinpoint inclined plane two opposite sides in described skin test injection syringe respectively of determining lobe and syringe needle.

Description

Skin test injection syringe

Technical field

The present invention relates to a kind of syringe, relate in particular to a kind of skin test injection syringe.

Background technology

Skin test is the abbreviation of skin (or Intradermal) sensitization test.Use clinically 1ml injection to do skin test to patient.In clinic material, the requirement of regulation intradermal injection needle angle is 5 degree.But in clinical manipulation process, the stability of needle angle is wayward, need the stable of nurse's technology, it is accurate that angle is affectedly bashful.In clinical, new nurse (working time≤2 year) intradermal injection success rate is relatively low.In addition, in intradermal injection operating process, needle point enters after skin corium, needs the junction of nurse's finger presses syringe needle and needle handle to keep pin hole upward.Often occur causing skidding off of syringe needle to make to inject unsuccessfully due to the rolling of needle handle.In addition, inserting needle is crossed dark or excessively shallow, and skin mound is unsuccessful plays or the size that plays on skin mound can affect the result of skin test.Repeat intradermal injection, not only can spend a large amount of working time of nurse, also can increase patient's misery.

Utility model content

In view of the above problems, this utility model is intended to propose a kind of skin test injection syringe that can guarantee needle angle.The second object of the present utility model is proposing a kind of syringe that prevents that skin test injection syringe from rolling.The second object of the present utility model is proposing a kind of written instructions syringe that can point out depth of needle.

In order to reach above-mentioned purpose, skin test injection syringe of the present utility model, it comprises syringe and syringe needle, further comprise that needle angle determines lobe, described needle angle determines that lobe top becomes 5 ° of angles with the line of needle tip and the body of syringe needle, and described needle angle determines that the pin hole of lobe and syringe needle is respectively the two opposite sides with described skin test injection syringe.

Preferably, described needle angle determines that lobe is arranged on the junction of syringe and syringe needle.

Preferably, described needle angle determines that lobe is arranged on syringe outside.

Preferably, described needle angle determines that the top of lobe forms the plane of extension, with skin test injection syringe described in stable support.

Preferably, described extended planar becomes 5 ° of angles with the body of syringe needle.

Preferably, at described needle angle, determine the opposition side of lobe, be provided with and press platform part.

Preferably, on described syringe needle, further comprise depth of needle indicatrix.Described depth of needle indicatrix is apart from the bottom 0.05-0.1mm of the pinpoint inclined plane of syringe needle.

Injector for skin test of the present utility model, determines lobe owing to having needle angle, only need guarantee that needle angle determines lobe and contact skin during use, and the angle that just can determine syringe needle and skin is 5 ° that stipulate.Because needle angle is determined the plane that lobe becomes to extend, syringe is by after being pressed on skin, and difficult rolling, avoids the sliding pin causing due to rolling.Owing to being provided with depth of needle indicatrix on syringe needle, medical personnel can determine depth of needle exactly, can inserting needle too not dark or too shallow.

The specific embodiment

Below, being elaborated to skin test injection syringe of the present utility model by reference to the accompanying drawings.

As shown in Figure 2-5, similar with conventional syringe, skin test injection syringe of the present utility model comprises syringe 1, push rod 2, piston 3, syringe needle 4.

In addition, skin test injection syringe of the present utility model also comprises that needle angle determines lobe 5.Needle angle determines that lobe 5 tops become 5 ° of angles with the line on syringe needle 4 tops with the body of syringe needle.The pinpoint inclined plane 7 that needle angle is determined lobe 5 and syringe needle is the two opposite sides in skin test injection syringe respectively.

Needle angle determines that lobe 5 can be arranged on the junction of syringe 1 and syringe needle 4, as shown in Figure 2,3.Needle angle determines that lobe 5 also can be arranged on syringe 1 outside (not shown).As long as needle angle is determined the position of lobe 5 and can be guaranteed that the body of syringe needle guarantees that when injection with the angle of skin be 5 °.

Needle angle determines that the top of lobe 5 forms the plane of extension, with stable support skin test injection syringe.As shown being ladder plane, can be also other shapes such as rectangle, circle, triangle, ellipse here, if can stable support at patient's skin surface.

Although not shown in figure, extended planar can become with the body of syringe needle 45 ° of angles, now extended planar is not parallel with the body of syringe needle as in Figure 2, but becomes 5 ° of angles with the body of syringe needle.Like this, needle angle can be guaranteed, supporting & stablizing can also be guaranteed.

At needle angle, determine the opposition side of lobe 5, be provided with and press platform part 6.Pressing platform part 6 can be circle, ellipse, rectangle etc., as long as facilitate medical personnel to press.Conventionally, press platform part 6 and form flat pattern, it is little that its area can form the plane of extension than the top of lobe 5.Like this, at this head, thrust after skin, medical personnel can press platform part 6, handled easily by finger presses.

As shown in Figure 5, on syringe needle, further comprise depth of needle indicatrix 8.Depth of needle indicatrix 8 is apart from the bottom 0.05-0.1mm of the pinpoint inclined plane 7 of syringe needle.For medical personnel provide distance scale indication accurately.

During use, needle angle is determined to the needle point of lobe 5 and syringe needle 2 is against skin surface, guaranteed 5 ° of inserting needles, light thorn syringe needle, makes syringe needle thrust the degree of depth and arrives depth of needle indicatrix 8, presses platform part 6 and guarantees the stable of syringe, then push appropriate amount of drug, extract syringe needle, complete injection.

Injector for skin test of the present utility model, the drawback that can well evade needle angle and needling length in intradermal injection in the past.Guarantee needle angle, the depth of needle of syringe needle, can guarantee that syringe needle does not roll simultaneously, effectively improve intradermal injection success rate, the repetitive operation that minimizing causes because of error, improve nurse job efficiency and professional gratification, reduce patient's misery, increase the sense of trust of patient to medical personnel, improve medical care satisfaction, promote the harmonious development of doctor-patient relationship.
