Abstract
The utility model discloses an automatic control dosing switch of a disposable infusion pump. The automatic control dosing switch of the disposable infusion pump comprises a key, an upper shell, a lower cover, a transparent cover plate, a medicine bag pressing plate, an automatic control spring pin, an automatic control spring and an automatic control spring housing. The upper shell is provided with a spring pin clamping groove used for fixing the automatic control spring and the key and meanwhile provided with a medicine tube clamping groove used for fixing a medicine outlet tube. The key is fixed to the upper shell together with the automatic control spring through the automatic control spring pin to form a lever with the automatic control spring pin as the fulcrum. A protruding block is designed at one end of the key; when the key is not pressed, the medicine outlet tube is pressed to be flat by the protruding block due to elasticity of the spring, and liquid medicine in a medicine bag cannot flow to a patient through the medicine outlet tube; when the key is pressed, the key generates down-pressing acting force on the medicine bag pressing plate, the liquid medicine in the medicine bag is extruded out because of pressing, meanwhile, the protruding block at the other end of the key is lifted up, the pressure on the medicine outlet tube is removed, and the extruded liquid medicine flows to the patient through the medicine outlet tube. The automatic control dosing switch of the disposable infusion pump is simple and reasonable in structure and high in using performance and is used for adding a liquid medicine dosage to relieve pain.
Description
Technical field
This utility model relates to clinical transfusion field, relates in particular to the patient-controlled administration switch of applying on disposable use infusion pump.
Background technology
The main clinical practice of disposable use infusion pump is in postoperative injection analgesic, adopting the tension force of silicon capsule is energy and power, by microporous pipe, control flow, by selected suitable specification and the analgesic of doctor, a kind of releasing or the lenitive disposable use medical apparatus and instruments of transferring to patient " self management ", be applicable to vein epidural space and subcutaneous micro-infusion administration functions again.
The disposable use infusion pump of automatic control administration includes automatic control administration parts, patient can select autonomous dosing according to self pain situation, and this wherein the effect of autocontrol switch just seem particularly important, existing disposable use infusion pump self-control switch complex structure, design accuracy is low, manufacturing process is loaded down with trivial details, and serviceability is not high.
Utility model content
Technical problem to be solved in the utility model is to provide the infusion pump self-control switch that a kind of structure is more reasonable, safety in utilization is higher.
This utility model is that to solve the problems of the technologies described above the technical scheme of employing as follows:
Disposable use infusion pump automatic control administration switch, comprises button, upper casing, lower cover, transparent cover plate, medicated bag pressing plate, automatic control spring catch, automatic control spring, automatic control spring housing.On upper casing, be provided with spring catch draw-in groove for fixedly automatic control spring and button, be provided with pencil draw-in groove for fixing drug discharging tube simultaneously.Upper casing and lower cover edge of opening are mutually closed and be fixedly connected with.Upper casing top is provided with key opening, and automatic control button top coupling is arranged in key opening, and button is fixed on upper casing together with automatic control spring by automatic control spring catch, forms one and take the lever that automatic control spring catch is fulcrum.Button one end is designed with a projection, and while not pushing button, the elastic force of spring makes this projection that drug discharging tube is flattened, and the medicinal liquid in medicated bag can not flow to patient by drug discharging tube.While pushing button, button produces a suppressing action power to medicated bag pressing plate, and the medicinal liquid pressurized in medicated bag is extruded, meanwhile, the projection of the button other end lifts, and unclamps the pressure to drug discharging tube, drug discharging tube arrives unimpeded state by the elastic recovery of silica gel, and the medicinal liquid of extruding flows to patient through drug discharging tube.Medicated bag is provided with drug-feeding tube and drug discharging tube, and medicated bag, drug-feeding tube and drug discharging tube are arranged on transparent cover plate.Medicated bag and the button projection section of pressing down drug discharging tube are held by a transparent cover plate, guarantee that medicated bag and drug discharging tube can be subject to corresponding downforce.Drug-feeding tube is connected with external device (ED) through the hole that is arranged at upper casing and lower cover junction with drug discharging tube.
The disposable use infusion pump self-control switch of said structure, when not working, spring force makes button one end projection flatten drug discharging tube; During use, push button and make the projection of button one end lift the flattening of unclamping drug discharging tube, by medicated bag pressing plate, medicated bag is produced the extruding force of a moment simultaneously, make medicinal liquid by drug discharging tube, flow to patient from medicated bag.Send out button, spring force flattens drug discharging tube again, stops that medicinal liquid continues to flow to patient, and meanwhile, due to the extruding having lost medicated bag, medicated bag is topping up again, for medicinal liquid is prepared in automatic control administration next time, thereby completes patient-controlled administration process.This apparatus structure is simple, rationally, easily manufactured, and serviceability is high, is a kind of disposable use infusion pump automatic control administration switch of novelty.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the disposable use infusion pump of this utility model automatic control administration switch schematic diagram.
In figure: 1: button
2: upper casing
3: lower cover

The specific embodiment
Fig. 1, Fig. 2 have provided disposable use infusion pump automatic control administration switch, comprise button 1, upper casing 2, lower cover 3, transparent cover plate 4, medicated bag pressing plate 5, automatic control spring catch 6, automatic control spring 7 and automatic control spring housing 8.During installation, by automatic control spring catch 6, automatic control spring 7 and automatic control spring housing 8 are installed to the respective card slot of upper casing 2 together with button 1, medicated bag pressing plate 5 is put into, then medicated bag is lain on medicated bag pressing plate 5, drug discharging tube, by draw-in groove process from the projection of button 1 one end, is loaded onto transparent cover plate 4 afterwards, and drug discharging tube is drawn from the draw-in groove of upper casing 2, load onto lower cover 3, complete installation.This switch simple installation, by lever principle, carries out on-off control by the elastic force of spring.
During use, due to the contractility of infusion pump silica gel reservoir, make medicinal liquid enter medicated bag, and be full of whole medicated bag, now, due to the elastic force of spring, drug discharging tube receives that extruding is flattened it, has stopped that medicated bag medicinal liquid flows to patient.During client need, can open automatic control administration switch, press lower button 1, can make the medicinal liquid storing in medicated bag flow to patient, alleviate patient's pain.Send out button 1, medicated bag is topping up again again, for automatic control administration is next time prepared.This switch is easy to use, effectively, can increase dosage according to client need, thereby alleviate patient's pain.
