Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] The present invention provides a syringe capable of micro-control injection, such as figure 1 , figure 2 and image 3 As shown, the syringe includes a syringe 1, a piston 2 that moves in the syringe 1 to absorb or squeeze liquid, and a piston connected to the piston 2 for driving the piston 2 to move in the syringe 1. Piston rod 3, the two ends of the syringe 1 are the hand-held end and the liquid inlet and outlet respectively, and one end of the piston rod 3 extends into the syringe 1 from the hand-held end and is connected with the piston 2. There is a handle 4 on the port outer wall o...

The invention provides an injector capable of micro-controlling liquid injection and belongs to the field of injections. The injector comprises a needle cylinder, a piston and a piston rod, wherein the piston moves in the needle cylinder to suck or squeeze liquid, and the piston rod is connected with the piston and used for driving the piston to move in the needle cylinder; and the two ends of the needle cylinder are a handheld end and a liquid inlet and outlet end respectively. One end of the piston rod extends into the needle cylinder from the handheld end to be connected with the piston, and a handheld part is arranged on the outer wall of a port of the handheld end; the piston rod is rotationally connected with the piston; the needle cylinder is provided with a conversion structure used for controlling the piston rod to move linearly or rotationally. The syringe meets the traditional straight push and pull liquid taking or liquid injection, can be converted into a threaded connection mode, and can effectively realize the micro control of the liquid amount by combining with the scales on the needle cylinder, thereby meeting the use in special liquid injection environments.
Description
technical field [0001] The invention belongs to the technical field of syringes, in particular to a syringe capable of micro-controlling liquid injection. Background technique [0002] Syringes are a common medical appliance, and the emergence of syringes is an epoch-making revolution in the field of medical appliances. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out, the liquid Or the gas is inhaled from the small hole at the front of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. [0003] Traditional syringes generally pull the piston rod in a straight line to drive the piston to move in a straight line in the syringe, so as to achieve the purpose of injection. However, it is difficult to control the manual p...
