Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows.
It is explained in detail below with reference to the structure that Fig. 1, Fig. 2, Fig. 3 stablize medical anesthetic injecting device to the present invention.One
Kind stablizes medical anesthetic injecting device, including shunts needle 1, and the shunting needle 1 is connected with needle stand 2, the needle stand 2 and injection tube
3 are connected, and the injection tube 3 is connected with relay piston 4, the relay piston 4 and relay piston bar 9, the relay piston
Bar 9 is connected with active piston bar 6, and the active piston bar 6 is connected with active piston 5, the active piston bar 6 and driving
Nut 8 is connected, and the driving nut 8 is connected with limit rack gear 7, and the relay piston bar 9 is connected with turntable 14, described
Turntable 14 is connected with raised bar 13, and the injection tube 3 is connected with containing mark cylinder 17, and the injection tube 3 is dedicated PP system
At material is as follows according to weight ratio ingredient: melting means PP50-60 parts high, 1-5 parts of PP feed back, 10-15 parts of toughener, white changes
2-3 parts of agent, 0.1-2 parts of white materbatch, 1-2 parts of polyethylene octene elastomer, 3-4 parts of SEBS of property.
The injection tube 3 is connected with fixture nut 10.
The fixture nut 10 is connected with limited block 12.
