Description

Push injection speed prompt structure Technical Field The utility model relates to the field of oral therapeutic equipment, in particular to a push injection speed prompting structure. Background In the field of modern oral treatment restoration, an oral material injector is used as a key tool, and is mainly used for accurately injecting a fluid material (such as restoration resin) into a target part of an oral cavity or teeth, and the operation effect directly influences the restoration quality. Currently, existing syringes are difficult to effectively evaluate bolus rates, and doctors rely primarily on their own experience and hand feel to control bolus rates when using manual syringes to bolus materials. The operation mode lacks accurate quantification standard, is difficult to ensure uniformity and stability of the injection speed in the whole operation process, and restricts the fine operation level of the oral cavity restoration treatment. Taking dental caries restoration as an example, when the existing oral cavity material injector is used for injecting restoration materials, improper injection speed is extremely easy to cause a series of problems that when the injection speed is too high, the materials are easily involved in air in the filling process so as to form holes, and when the injection speed is too low or uneven, the filling uniformity of the materials is poor, and the shape and structure of the restoration body are affected. These problems, caused by improper bolus rate control, not only reduce the aesthetics and functionality of the prosthesis, but may also have serious clinical consequences. For example, food residues and bacteria are easily left in holes and uneven areas formed during filling, and secondary caries, pulpitis and other complications are caused, which causes long-term harm to oral health of patients. In the prior art, a syringe with a certain speed measuring function exists, but the syringe is special equipment, and the syringe is a consumption instrument, so that the use cost is increased, and in addition, the structure is complex, so that the problems of the use reliability and the operation convenience exist. Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present utility model. Disclosure of utility model The utility model aims to provide a push injection speed prompt structure. In order to achieve the above purpose, the utility model adopts the following technical scheme: A push injection speed prompt structure aims at an injector, the injector comprises a cylinder body and a push injection handle, and the push injection speed control structure comprises: The fixing piece is arranged on the cylinder body; A pressing piece attached to the injection handle; the speed measuring mechanism is at least connected with the pressing piece; The prompting piece is arranged on the fixing piece and is electrically connected with the speed measuring mechanism; The injection speed control structure has a speed measurement state: And in a speed measurement state, the pressing piece and the injection handle synchronously move, the speed measurement mechanism detects the moving speed of the pressing piece and transmits speed measurement information to the prompting piece, and the prompting piece prompts the current injection speed according to the speed measurement information. When the injector works, the cylinder body is kept motionless, the pushing handle carries out mobile pushing operation, at the moment, the fixing piece and the cylinder body are kept relatively static, and the pressing piece and the pushing handle are kept relatively static. In the scheme, an operator applies force to the pressing piece, the pressing piece drives the pushing handle to complete pushing operation, in the pushing process, the speed measuring mechanism obtains the pushing speed of the pushing handle by detecting the moving speed of the pressing piece, the prompting piece prompts the current pushing speed to the operator according to the speed measuring information of the speed measuring mechanism, and the operator timely adjusts the acting force applied to the pressing piece according to the prompting of the prompting piece so as to adjust the pushing speed. Through the cooperation of speed measuring mechanism and suggestion piece, operating personnel can in time clearly know current bolus speed, replaces traditional mode through individual perception judgement bolus speed to be favorable to guaranteeing homogeneity and the stability of bolus speed, promote to realize meticulous injection, treatment and patient experience when improving the syringe and being used for oral treatment. The prompting piece is arranged on the fixing piece and is close to the speed measuring mechanism, so that an operator can receive prompting information of the prompting piece in time. The manner of data transmission is an existing arrangement and will
