Abstract
The utility model relates to a peristaltic device for an infusion pump provided with an elastic infusion-stopping valve. The peristaltic device is composed of a crankshaft (1), a front elastic infusion-stopping valve (2), an extrusion block (6), a rear elastic infusion-stopping valve (5) and an extrusion baffle plate (4). An elastic infusion pipe (3) is arranged between the front elastic infusion-stopping valve (2), the extrusion block (6), the rear elastic infusion-stopping valve (5) and the extrusion baffle plate (4) The crankshaft (1) is matched with the front elastic infusion-stopping valve (2), the extrusion block (6) and the rear elastic infusion-stopping valve (5) in a tangent mode. The peristaltic device for the infusion pump provided with the elastic infusion-stopping valve is capable of avoiding liquid leakage caused by precision deviation of machining and assembly and abrasion during an infusion process.
Description
Technical field
This utility model relates to infusion pump in medical application, especially a kind of creeping device of infusion pump that has elasticity and stop liquid valve.
Background technology
Infusion pump in medical application is usually used in medicine or medicament to inject in patient body.Common creeping device of infusion pump by front only liquid valve block, only liquid valve block and crushing block are stuck in the elastic transfusion pipe in the middle of extruding baffle plate by certain sequential extruding afterwards, finally complete transfusion.Forward and backward only liquid valve block must firmly be pushed down tube for transfusion at the maximum position of clamping stroke, prevents leakage.Because different infusion pipeline wall thickness is variant, for fear of leakage or dieback, a lot of bedside infusion pump adopt elasticity extruding baffle plate to carry out the difference of compensating pipe wall thickness.And portable infusion pump is owing to being subject to the restriction of bulk often can not put into this elasticity extruding baffle mechanism.So current portable infusion pump all can only be used wall thickness dimension dedicated transfusion pipe or special consumptive material accurately.But, because the situation of excesssive gap between liquid valve block and extruding baffle plate also likely can occur to stop the wearing and tearing in deviation or the use procedure of processing, assembly precision in infusion process, thereby cause unexpected leakage, to patient, cause risk.Once there is the product recall of portable infusion pump in reason thus in recent years.
Summary of the invention
In order to overcome existing infusion pump rigidity, stop liquid valve block and may cause the deficiency of leakage, this utility model provides a kind of creeping device of infusion pump that has elasticity and stop liquid valve, the elasticity of this device is stopped liquid valve can compensate the gap deviation of stopping between liquid valve block and extruding baffle plate, enough thrusts are provided, avoid due to the accuracy error of processing, assembling and the leakage that wearing and tearing cause.Adopt the portable infusion pump of this creeping device can also use the infusion pipeline of different wall, make conventional tube for transfusion also can, for portable infusion pump, reduce use cost, expanded the range of application of portable infusion pump.In addition, compared with the elasticity extruding baffle plate adopting with bedside infusion pump, this has elasticity and stops the creeping device of infusion pump of liquid valve and have advantage simple in structure, with low cost, easy for installation.
This utility model solves the technical scheme that its technical problem adopts:
Have elasticity and stop a creeping device of infusion pump for liquid valve, described creeping device bent axle, front elasticity are stopped liquid valve, crushing block, rear elasticity and are stopped liquid valve, extruding baffle plate composition; Described elastic transfusion pipe is installed on described front elasticity to be stopped liquid valve, crushing block, rear elasticity and stops between liquid valve and extruding baffle plate; Described bent axle stops liquid valve, crushing block, rear elasticity with front elasticity respectively and stops that liquid valve is tangent to be coordinated; Described front elasticity is stopped liquid valve and rear elasticity, and to stop liquid valve arrangement identical, by top, only liquid spring, tabletting form.Described top is with buckle structure, by this buckle and described tabletting, fasten, and by described only liquid alligator clamp in the middle of top and tabletting.Square blind hole is arranged at described tabletting top, and four inner surfaces by blind hole and the described top outer surface guiding that cooperatively interacts, is linked in blind hole the inside by bottom, top.Compressed during described only liquid spring fitting, produce certain pretightning force.
Before during transfusion, elasticity is stopped liquid valve, rear elasticity and is stopped liquid valve and crushing block by crank-driven, by certain sequential extruding, is stuck in the elastic transfusion pipe in the middle of extruding baffle plate.When elasticity is stopped liquid valve and is pressed to maximum position downwards, can be extruded baffle plate and withstand by elastic transfusion pipe, the only compressed certain distance of liquid spring, now spring force can guarantee that elastic transfusion pipe is compacted.
When installation dimension deviation causes bent axle and the distance of extruding between baffle plate to become large or wearing and tearing occurring, in elasticity, stop liquid valve and be pressed to maximum position place downwards and stop the liquid spring corresponding variable in distance of a certain amount of compensation of upspringing.Now spring force still can guarantee that elastic transfusion pipe is compacted.
When installation dimension deviation causes bent axle and the distance of extruding between baffle plate to diminish, in elasticity, stop liquid valve and be pressed to maximum position place downwards and stop liquid spring and be further compressed the corresponding variable in distance of a certain amount of compensation.Now spring force still can guarantee that elastic transfusion pipe is compacted.
The beneficial effects of the utility model are can avoid in infusion process due to the accuracy error of processing, assembling and the leakage that wearing and tearing cause.Adopt the portable infusion pump of this creeping device can also use the infusion pipeline of different wall, make conventional tube for transfusion also can, for portable infusion pump, reduce use cost, expanded the range of application of portable infusion pump.In addition, compared with the elasticity extruding baffle mechanism adopting with bedside infusion pump, this has elasticity and stops the creeping device of infusion pump of liquid valve and have advantage simple in structure, with low cost, easy for installation.
