Injector clamping device

Abstract

The invention relates to an injector clamping device, which comprises a sliding block mechanism, a meshing mechanism and a clamping mechanism, wherein the sliding block mechanism is arranged on an injection pump screw in a sliding penetration way; the meshing mechanism is separably meshed with the screw in a movement way; the clamping mechanism rotates to clamp or loosen an injector under the driving of movement of the meshing mechanism; the sliding block mechanism comprises a hollow sliding block main body with a through hole allowing the screw to penetrate; the meshing mechanism is arranged in the sliding block main body in a way of moving backwards and forwards in directions close to and away from the through hole; the clamping mechanism is inserted into the sliding block main body in a rotating way, and is clamped with the meshing mechanism. The injector clamping device is simple in structure, low in cost, convenient to use and suitable for the clamping of injectors in various specifications on an injection pump.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a syringe clamping device. Background technique [0002] In the existing syringe pump, the clamping of the syringe on it is usually realized by claws, and there are several ways as follows: [0003] 1. Fixed claw: such as figure 1 As shown, the claw 101 is fixedly arranged on a slider 102, and the push handle 300 of the syringe is clamped in the gap between the claw 101 and the slider 102, and the push handle 300 of the syringe is pushed back and forth by the slider 102; It is difficult for this kind of fixed claw to clamp the push handle 300 tightly, and there is a gap between the push handle 300 and the claw 101 . [0004] 2. Telescopic jaws: such as figure 2 As shown, the claw 201 is installed on the slider 202 through the spring 204, and the stretching force of the spring 203 drives the claw 201 to sandwich the push handle 300 of the syringe; [0005] 3. Rotary claw: s...

Problems solved by technology

[0006] However, the above-mentioned first and second types of claws need to be lifted and placed in the claws on the slider when the slider moves close to the syringe push handle during use, which is inconvenient to use; the third type of claw is made of The realization of gear drive requires a certain space on the slider to install the gear, the structure is complex and the cost is high
