Description
Technical Field
The utility model relates to the technical field of medical injection instruments, in particular to a disposable nine-hole injection needle head and an injector.
Background
In clinical medical practice, a needle for injection is a common medical device. The traditional syringe needle is a single-hole one-needle-point injection hole, and due to the unreasonable mechanical structure of the single-hole syringe needle, the traditional syringe needle has the following inevitable defects in clinical application:
the single-hole needle has the advantages that 1, the pain is heavy (mainly swelling pain), although the pain is affected by medicines and the injection speed, the pain is mainly caused because the single-hole needle can only form a single liquid medicine absorption surface in skin tissues during injection, and the absorption surface is not beneficial to the rapid and uniform absorption of liquid medicine, so that liquid medicine is formed in the skin tissues and is stored, and subcutaneous sensory nerve endings are pressed.
2, when injecting to different cortex to single skin tissue, because the unicity of traditional syringe needle, need relapse the different degree of depth and inject, the syringe needle can oppress the damage to single skin tissue face, influences the absorption to the liquid medicine to the pinhole pierces through repeatedly at subcutaneous position will cause the blood stasis blue or green or mistake and go into vascular embolism etc. and then reduces the security and the accurate nature of injection, thereby influences treatment.
In view of the above, the present invention is to overcome the above disadvantages, and to provide a nine-hole needle for injection, which can improve the injection permeability of the liquid medicine for absorption, and has good injection targeting property and improved curative effect.
Disclosure of Invention
An object of the utility model is to provide a disposable nine-hole syringe needle and syringe to solve in the prior art when injecting to different cortex to single skin tissue, because the unicity of traditional syringe needle, need to inject at different degree of depth repeatedly, the syringe needle can oppress the damage to single skin tissue face, influence the absorption to the liquid medicine, and the pinhole pierces through repeatedly at the subcutaneous position will cause the bruise blue or miss vascular embolism etc. and then reduce the security and the precision of injection, thus influence the technical problem of treatment; the utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.
In order to achieve the above purpose, the utility model provides a following technical scheme:
