Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an infusion pump with an automatic displacement function of an infusion tube.
Background
The infusion pump device continuously extrudes the infusion tube through the blades on the peristaltic pump, thereby controlling the speed and the precision of the infusion. The elasticity of the same part of the infusion tube is easy to change under the long-time extrusion of the peristaltic pump, so that the infusion speed is changed finally, and the infusion precision of the device cannot be effectively guaranteed.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the infusion pump with the automatic infusion tube displacement function is provided, so that one or more technical problems in the prior art are solved, and at least one beneficial selection or creation condition is provided.
The solution of the invention for solving the technical problem is as follows:
the utility model provides an transfer pump with transfer line automatic displacement function, includes the transfer pump shell, the transfer pump shell is provided with the transfer line and places the district, the transfer pump shell is provided with the displacement subassembly, the displacement subassembly includes displacement drive wheel and driving motor, driving motor installs in the transfer pump shell, driving motor drive displacement drive wheel is rotatory, the displacement drive wheel sets up in the transfer line and places the district, the displacement drive wheel rotates with the transfer pump shell to be connected, the transfer pump shell is connected with and is used for pressing from both sides the tight wheel of clamp of the transfer line of tight peripheral hardware with the displacement drive wheel cooperation.
Through the scheme, the clamping wheels and the displacement driving wheels clamp the infusion tube, and the driving motor drives the displacement driving wheels to rotate forwards and backwards repeatedly, so that the infusion tube is driven by the displacement driving wheels to move forwards and backwards, the phenomenon that the peristaltic pump extrudes the same part of the infusion tube for a long time is avoided, and the adverse effect of reduction of the infusion progress caused by reduction of the elasticity of the infusion tube is avoided.
As a further improvement of the technical scheme, the displacement driving wheel is provided with a fitting groove which is a semi-circular groove.
Through the scheme, the arrangement of the fitting groove prevents the liquid conveying pipe from deviating gradually and finally separating from the clamping condition of the displacement driving wheel and the clamping wheel to the liquid conveying pipe when the displacement driving wheel and the clamping wheel drive the liquid conveying pipe to move back and forth, and the normal operation of the displacement assembly is ensured.
As a further improvement of the above technical solution, the driving motor is mounted inside the infusion pump housing.
Through above-mentioned scheme, driving motor has been avoided driving motor to install in the outside of transfer pump shell in the inboard of transfer pump shell, avoids the transfer line to touch driving motor and leads to the damage of transfer line.
As a further improvement of the technical scheme, the driving motor and the displacement driving wheel are in transmission through a gear belt.
The invention has the beneficial effects that: the peristaltic pump is prevented from extruding the same part of the infusion tube for a long time, and the adverse effect of the reduction of the infusion progress caused by the reduction of the elasticity of the infusion tube is avoided.
The invention is used in the technical field of medical instruments.
