Description

Technical Field

[0001] The present invention relates to the technical field of injection equipment, in particular to an automatic injection positioning device and a control method for endocrine clinics. Background Art

[0002] Endocrine diseases are syndromes that occur when the secretory function and structure of endocrine glands or endocrine tissues themselves are abnormal. They also include syndromes caused by abnormal hormone sources, abnormal hormone receptors, and physiological disorders caused by abnormal hormone or substance metabolism. In clinical treatment, some diseases require the use of injection devices to quantitatively and regularly inject liquid medicine.

[0003] When the existing endocrine clinical automatic injection positioning device is in use, since some drug solutions need to be injected in batches at regular intervals and in fixed quantities, the pre-mixed drug solution stored in the injection device will be separated from its components after being left stationary for a long time, thereby affecting the uniformity of the drug solution mixing. The separation of drug solution components will affect the effect of the drug solution after injection, thereby affecting the therapeutic effect of endocrine clinical treatment. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic injection positioning device and control method for endocrine clinics to solve the problems raised in the above background technology.

When the portion of the injection piston rod (5) with the spiral groove (11) enters the rotating sleeve (10), the spiral groove (11) on the injection piston rod (5) cooperates with the thread groove on the inner wall of the rotating sleeve (10) to drive the rotating sleeve (10) to rotate. The rotating sleeve (10) drives the injection barrel (4) to rotate. When the injection barrel (4) rotates, the elastic band (13) elastically deforms. When the spiral groove (11) on the injection piston rod (5) is offset from the rotating sleeve (10), the elastic band (13) automatically rebounds to pull the injection barrel (4) to reset, so that the injection barrel (4) can be repeatedly rotated during injection, so that the liquid medicine in the injection barrel (4) can be mixed.
