Abstract
The utility model relates to a needle used for the injection between a soft tissue and a hard tissue, which comprises a needle body and a needle joint for connecting the needle body or comprises a needle body and a syringe for connecting the needle body, wherein the needle body comprises an upper needle body and a lower needle body. Furthermore, a certain angle beta is formed between the upper needle body and the lower needle body, the angle beta can be manually regulated between 0 DEG and 90 DEG, preferably between 15 DEG and 75 DEG, the angle is convenient for injection inside a gap between the soft tissue and the hard tissue, such as a gap between a gum and teeth and a gap between a nail and a finger, and especially convenient for injection inside a mouth cavity, thereby an injected person can inject oneself . In addition, the needle tip is positioned on the tail end of the upper needle body, an angle alpha is formed between the plane of the needle tip and the upper needle body, and the range of the angle alpha is between 70 DEG and 90 DEG, preferably between 85 DEG and 90 DEG, thereby the needle tip is blunted and can not pierce the skin and the soft tissue during injection.
Description
Technical field
This utility model relates to the syringe needle in a kind of medical field, relates in particular to a kind of syringe needle that is used for injection between soft tissue and the sclerous tissues.
Background technology
The present injection needle that uses, needle body is type linearly, no bending angle, the plane of needle point 1 ' part becomes a smaller angle α (as depicted in figs. 1 and 2) with needle body 2 ', thereby makes needle point very sharp-pointed, is convenient to the injection that prick skin or tissue carry out medicinal liquid.
If but under the situation for the treatment of between soft tissue and the sclerous tissues, as gingiva or fingernail, only need injecting liquid drug in the gap between soft tissue and the sclerous tissues, and do not wish skin or soft tissue are punctured, in order to avoid medicinal liquid produces stimulation or bad anaphylaxis etc. takes place wound, simultaneously owing to need in oral cavity or first seam wait small space of this type of difficult operation, carry out injection operation, this moment, common injection needle just can not satisfy this type of special demand, thus press for a kind of neither can prick skin and the syringe needle conveniently injected again of soft tissue.
The utility model content
A kind of syringe needle that is used for injection between soft tissue and the sclerous tissues that this utility model provides, neither can prick skin and soft tissue conveniently inject again.
In order to achieve the above object, this utility model provides a kind of syringe needle that is used for injection between soft tissue and the sclerous tissues, comprises needle body and the syringe needle joint that is connected needle body, and the other end of this syringe needle joint connects syringe;
Described needle body comprises bottom needle body and top needle body, between top needle body and the bottom needle body at an angle, angular range is at 0 °～90 °, be preferably 15 °～75 °, can this angle of manual adjustments, inject in the gap of being convenient between soft tissue and sclerous tissues, gap such as gingiva and tooth, and in the gap of fingernail and finger, especially be convenient in the oral cavity, inject, also can be injected by injector oneself from line operate;
Described needle point is positioned at the end of top needle body, and angular range is 70 °～90 ° between needle point plane and the top needle body, is preferably 85 °～90 °, thereby makes the needle point passivation, can prick skin and soft tissue when injection.
A kind of syringe needle that is used for injection between soft tissue and the sclerous tissues also is provided, comprises needle body and the syringe that is connected needle body;
Described needle body comprises bottom needle body and top needle body, between top needle body and the bottom needle body at an angle, angular range is at 0 °～90 °, be preferably 15 °～75 °, can this angle of manual adjustments, inject in the gap of being convenient between soft tissue and sclerous tissues, gap such as gingiva and tooth, and in the gap of fingernail and finger, especially be convenient in the oral cavity, inject, also can be injected by injector oneself from line operate;
Described needle point is positioned at the end of top needle body, and the angular range between needle point plane and the top needle body is 70 °～90 °, is preferably 85 °～90 °, thereby makes the needle point passivation, can prick skin and soft tissue when injection.
A kind of syringe needle that is used for injection between soft tissue and the sclerous tissues that this utility model provides, inject in the gap of being convenient between soft tissue and sclerous tissues, and can prick skin and soft tissue.
