Problems solved by technology
[0002] In our daily life, we are often exposed to drug injections. Generally, disposable syringes are used to complete the injection process during drug injections, which can ensure the safety of drug injections. For the injection of the same drug, the use of disposable syringes will cause a large number of injuries. Waste, resources can be saved by changing the needle without changing the barrel. The injection depth of the traditional syringe needle cannot be effectively controlled, and it is easy to cause a certain degree of side effects to the patient. The injection at a fixed depth of the needle cannot be effectively controlled. A drug syringe with fixed depth injection can solve the above problems

The invention discloses a medicine injector for fixed-depth injection, which comprises a needle cylinder. A liquid medicine cavity with a downward opening is formed in the lower end face of the needle cylinder in a communicating mode, a plunger capable of sliding up and down is arranged on the inner wall face of the liquid medicine cavity, a push rod extending out of the lower end face of the needle cylinder is fixedly arranged on the lower end face of the plunger, and a push plate is fixed on the lower end face of the push rod. Fixed-depth injection of a needle head can be achieved, the depth of the needle head pricking into muscles is effectively standardized, the uncertain side effect of a patient caused by too deep pricking of the needle head is avoided, meanwhile, the device can spontaneously destroy the needle head after injection, secondary recycling of the needle head is avoided, cross infection and other symptoms caused by medicine and blood are effectively avoided, the safety of medicine injection of a patient is effectively guaranteed, and meanwhile the device is suitable for operation specifications of medical staff and convenient to widely popularize.
Description
technical field [0001] The invention relates to the field of drug injection, in particular to a drug injector for fixed-depth injection. Background technique [0002] In our daily life, we are often exposed to drug injections. Generally, disposable syringes are used to complete the injection process during drug injections, which can ensure the safety of drug injections. For the injection of the same drug, the use of disposable syringes will cause a large number of injuries. Waste, resources can be saved by changing the needle without changing the barrel. The injection depth of the traditional syringe needle cannot be effectively controlled, and it is easy to cause a certain degree of side effects to the patient. The injection at a fixed depth of the needle cannot be effectively controlled. A drug injector for injection with a fixed depth can solve the problems referred to above. Contents of the invention [0003] In order to solve the above problems, this example designs ...
