Description

Autoinjector structure

technical field

The utility model relates to an automatic injector structure, which is especially suitable for hospitals, clinics or similar places with medical activities.

Background technique

Physical health is the first condition of life. If there is a disease in the body, nothing can be done smoothly. When there is a disease in the body, it is natural to turn to a doctor and use the professional knowledge of the doctor to solve the pain for the patient. The pain of the disease is nothing more than injections, medicines, or further surgery, surgery and other methods.

Take dentistry as an example. Tooth pain is a common dental disease. The main cause of tooth pain is most of the tooth decay. If the hole is too deep or too large, the nerve needs to be extracted. After the nerve is extracted, the braces will be used to cover the extracted tooth. When the nerve is extracted from the patient, the patient’s pain cannot be avoided. The dentist will first Anesthesia needles are injected into the patient's gums to anesthetize the gums for smooth dental treatment.

Please refer to Fig. 1, the anesthetic syringe used by the dentist is a metal syringe A, the metal syringe A is provided with a metal hollow tube, the surface of the metal hollow tube has a slot A1, and one end of the metal hollow tube is provided with a needle junction A2, the needle The junction A2 and the slot A1 are connected to each other, and the other end of the empty metal tube is combined with a movable push rod A3, and the end of the movable push rod A3 has a threading part A4, and the metal syringe A is located at the end of the slot A1. There is also a set of ring A5; when the doctor wants to inject anesthesia needle, the movable push rod A3 of the metal syringe A is pulled back, so that the anesthetic agent B is put into the slot A1 of the metal syringe A, and then the movable push rod A3 is placed Open, insert the front end of the movable push rod A3 into the bottle of anesthetic agent B, and lean against the drug push piece, and then combine the needle with the needle joint A2 of the metal syringe A, so the dentist inserts the needle into the patient's In the gums, pass the index finger through the ring A5 of the sleeve, and then insert the thumb into the sleeve A4, and use the thumb to apply force to the sleeve A4, so that the front end of the movable push rod A3 squeezes the medicine pusher, and Let the anesthetic agent B enter the patient's gums along the needle to achieve the effect of anesthesia.

However, when the above-mentioned metal syringe A is in use, the dentist needs to exert greater strength to inject the anesthetic agent into the patient's gums. If it is only used 3 to 5 times a day, it will not cause damage to the doctor's hand, but the patient's hand will not be damaged in one day. The number of patients is not only 3 to 5 people, so long-term accumulation may cause a kind of occupational injury to the hands of the dentist. In view of this, the inventor expects to provide an automatic injector that reduces the damage to the hands of the dentist The structure is to study and design with great concentration, so as to provide specific ethnic groups to use, which is the creative motivation of the utility model.
