Embodiment Construction
[0011] The virtual main shooter model of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0012] see figure 2 As shown, the base part: figure 2 It is composed of 01~08 parts, and the base 07 and the shaft 08 are the core parts of the base. There is a stepped hole in the center of the base 07, in which the bearing 06 is placed, and the bearing 06 is used to cooperate with the rotating shaft 08, and the collar 05 and the shoulder of the stepped hole of the base 06 are used to limit the axial position; the rotating shaft 08 is in the center hole of the base 06 Internal rotation, through the relative rotation of the base 07 and the rotating shaft 08, the syringe is rotated in the horizontal plane; the shaft head of the rotating shaft 08 is provided with a limit block 04 and a horizontal rotation potentiometer, the limit block 04, the horizontal rotation potentiometer rotary rod and The rotating shaft 08 is coaxially insta...

The invention discloses a hand model for virtual injection which is used for simulating the process of intravenous injection and realizes operation at three degrees of freedom and in six directions. The mechanical structure of the hand model for virtual injection comprises a base part and an injection part. In the base part, a rotating shaft rotates in a center hole of a base, a limiting block and a rotary potentiometer are coaxially mounted on one side of the shaft head of the rotating shaft, the limiting block is used for limiting rotation in the horizontal rotation, and the rotary potentiometer is used for performing angle feedback in the horizontal rotation direction; and the two sides of the base are respectively equipped with a connecting plate, and the connecting plates fix the whole hand model for virtual injection and a casing. In the injection part, a push rod slides in a sliding hole of a push rod frame, the push rod is connected with a linear potentiometer and a pinhole, the linear potentiometer is used as a feedback element for the depth at which a needle is inserted in injection, and the pinhole is a connector for connecting a syringe; the push rod frame is fixed on a bracket with a half shaft and a rotary rod of the rotary potentiometer as shafts, and the rotary potentiometer is used for vertical angle feedback; and an electromagnet is used for simulating the feeling of puncture when a needle head penetrates through a blood vessel. Therefore, the whole process of injection and the simulation of the feeling of blood vessel penetration are achieved.
Description
technical field [0001] The invention relates to the field of medical teaching instruments, in particular to a virtual injection model. Background technique [0002] An in-depth understanding of the anatomical position of the dorsal veins and proficiency in the intravenous injection technique of the back of the hand are the basis of clinical nursing. Practice, more inconvenient classroom study of the student. Contents of the invention [0003] In order to solve the above problems, it is the purpose of the present invention to provide a virtual injection hand model with vivid image, stable structure, real response and which can be used for teaching. [0004] The technical scheme that the present invention adopts for realizing the above object is: [0005] Virtual injection hand model, including: base part and injection part. [0006] It is characterized in that: the base part is composed of a base, a rotating shaft, a connecting plate, a limit block, a horizontal rotary p...
