Abstract
The utility model relates to a medical instrument device, in particular to an air pressure injector used for a dental unit. The air pressure injector used for the dental unit comprises a needle head, an agentia bottle containing body, a pushing rod, an air pressure pushing device, a pipe and a dental unit standard socket. A piston and a cylinder are arranged in the air pressure pushing device, the piston is connected with the pushing rod, and the cylinder is connected with the pipe. The air pressure injector used for the dental unit is safe and reliable in operation, and medicine changing operation is convenient. The air pressure injector can be conveniently connected to the dental unit. Injection is controlled through a pedal switch of the dental unit, and automation is achieved. A hand cannot ache after operation for a long time, and labor amount is significantly reduced.
Description
Technical field
This utility model relates to the medical device technical field, is specially a kind of dental unit pneumatic injector.
Background technology
Need anesthesia in the dental operation, existing anaesthetic injection all is to finish by hand gun, and general this syringe has the push rod of syringe needle, ampoule housing and back, and syringe needle and ampoule all are that a pin one changes.Ampoule is placed in the ampoule housing, and syringe needle is inserted in the front, the bottle stopper contact push rod of back, and the medical worker manually promotes push rod from afterbody, injects.
This hand gun, during the injection anaesthetic, resistance is large during particularly to periodental ligament anesthesia.The anaesthetic injection that every day is a large amount of, the medical worker tires out, and easily causes malpractice.
Simultaneously, dentistry is widely used dentist's machine, is a kind of integration equipment with a plurality of standard interfaces, and standard interface provides air pressure, controls by foot switch.
The utility model content
In order to solve the defective of above-mentioned hand gun, in conjunction with the characteristics of existing dental unit, this utility model provides a kind of dental unit pneumatic injector, to realize automatization, reduces the amount of labour
Concrete technology case is:
A kind of dental unit pneumatic injector, comprise syringe needle 1, ampoule housing 2, push rod 3, air pressure thrust unit 5, pipeline 6 and tooth therapy apparatus standard socket 7, establish piston 51 and cylinder 52 in the wherein said air pressure thrust unit 5, described piston 51 connects push rod 3, is connected with pipeline 6 on the described cylinder 52.
Preferably, described push rod 3 is provided with a clawback bar 31.
Because adopt technique scheme, dental unit of the present utility model has such beneficial effect with pneumatic injector: handling safety is reliable, changes dressings easy to operate.Can connect easily on the dental unit, by foot switch control injection, realize automatization.The long-time operation hands can be not sour yet, the decrease amount of labour.
Description of drawings
Fig. 1 is embodiment structural representation of the present utility model.
The specific embodiment
Accompanying drawings concrete real mode of the present utility model, as shown in Figure 1, this dental unit will comprise syringe needle 1, ampoule housing 2 and push rod 3 with pneumatic injector, during use ampoule 4 is placed in the ampoule housing 2, before syringe needle 1 is arranged on ampoule housing 2, the bottle stopper 41 contact push rods 3 of ampoule 4, push rod 3 move and just promote bottle stopper 41 and move.The piston 51 of air pressure thrust unit 5 connects push rod 3, is connected with pipeline 6 on the cylinder 52, and the other end of pipeline 6 is provided with dental unit standard socket 7.Push rod 3 is provided with a clawback bar 31, can conveniently reset push rod, and clawback bar 31 is perpendicular to the short handle of push rod 3.
When using, dental unit standard socket 7 of the present utility model is inserted on the standard interface of dental unit, by the foot switch of dental unit, the control air inlet is injected.
