Impression material blending device for oral clinic

Abstract

The invention discloses an impression material blending device for oral clinical use. The device comprises a mounting box, a first discharging unit, a weight measuring unit, a second discharging unit,a water conveying unit, a material conveying unit, a discharging unit and a stirring unit, a fixed plate is fixed at the upper end of the interior of the mounting box; a fixing hole is formed in theupper side surface of the mounting box; a storage box is fixed in the fixing hole; openings are formed in the upper side face and the lower side face of the storage box. The lower side face of the storage box is fixed to the upper side face of the fixed plate. A discharging hole is formed in the upper side face of the fixed plate. The first discharging unit is installed in the installation box, alginate powder in the storage box enters a storage barrel through the first discharging unit, the weight measuring unit comprises a storage barrel, a discharging pipe, a connecting block, a spring, aninstallation plate, a fixing ring, a limiting rod and a weight sensor, the water-powder proportion can be accurately controlled, and powder and water can be fully blended.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an impression material blending device for clinical oral cavity. Background technique [0002] Tooth implantation and restoration is an important part of oral clinical medicine. The preparation of dental impression is the first process of dental implantation and oral restoration. Whether the impression can faithfully record and reproduce the subtle conditions of oral tissue will directly affect the quality of life. The shape and quality of the implanted and restored teeth will be related to the final restoration effect. Therefore, obtaining an accurate oral impression is very important for oral clinics. The impression is the negative model of the object, and the oral impression is the oral cavity. The negative model of the relevant tissue, the material used to make the impression is called the impression material. Domestic and foreign studies have shown that the performan...

[0002] Tooth implantation and restoration is an important part of oral clinical medicine. The preparation of dental impression is the first process of dental implantation and oral restoration. Whether the impression can faithfully record and reproduce the subtle conditions of oral tissue will directly affect the quality of life. The shape and quality of the implanted and restored teeth will be related to the final restoration effect. Therefore, obtaining an accurate oral impression is very important for oral clinics. The impression is the negative model of the object, and the oral impression is the oral cavity. The negative model of the relevant tissue, the material used to make the impression is called the impression material. Domestic and foreign studies have shown that the performance of the impression material directly affects the quality of the restoration. In clinical work, the oral impression film material is based on Alginate is the main material. At present, the mainstream alginate impression materials on the market are powder type and paste type, which need to be mixed with water or cement before use. The impression material after stirring is fine, with few air bubbles and good elasticity, so that the performance of the impression material can be maximized. However, in actual clinical application, it is affected by the experience and operation proficiency of doctors or nurses, and it is impossible to accurately control the impression material. The mixing method, mixing time and material ratio, these factors will cause the materials to not be fully mixed, uneven water absorption of the impression material will cause problems such as particles or a large number of air bubbles, so that the dental model made will have gypsum tumors in key parts, The surface of the model has defects such as missing, incisal end deformation, etc.
