Abstract
The utility model belongs to nursing experimental teaching supplies and discloses an infusion device for an intravenous infusion experiment. The infusion device is characterized in that a liquid backwashing funnel is communicated with an infusion bottle, and a Y shaped gas injection pipe which is communicated with infusion short pipe and is connected with an injector nipple is arranged above a murphy's dropper. The infusion device is for repeated exercise use of intravenous infusion air exhaust and infusion operation and has the significant advantages of expense saving, reduction of waste material discharge, improvement of teaching effect, acceleration of learning process, improvement of learning efficiency and the like.
Description
Technical field
The utility model belongs to nursing teaching apparatus field, relates to the nursing experimental apparatus, specifically proposes a kind of venous transfusion experiment transfusion device.
Background technology
In nursing experimental teaching, as when the Nursing Experimental Lesson Teaching student practises venous transfusion, often adopt medical Transfusion device and sterile liquid as the lab exercise utensil.
Existing transfusion device is only for the disposable exercise method for exhausting of learner and the impression of experiencing authentic operation.Owing to be full of liquid in the liquid-transport pipe-line, even if by infusion bottle is upright, make the infusion bottle pin expose liquid level, hold infusion bottle high, strengthen drop and treat that air enters in the woven hose liquid is displaced; Or extract the infusion bottle pin and carry out exhaust; Or take off liquid bottles, placement extreme lower position, and open transfusion long tube regulator, make liquid-transport pipe-line vertical with infusion bottle, utilize drop to make the interior liquid of liquid-transport pipe-line blow back into infusion bottle.But these methods all can't drain residual liquid and air in the liquid-transport pipe-line, can not again carry out exhaust training truly, again time and effort consuming.If use new transfusion device at every turn, can cause leaking because of the transfusion bottle stopper that repeatedly punctures, or because the exercise of exhaust repeatedly drains liquid in infusion bottle, all need again to change infusion bottle.This present situation has influence on learner's practice effect and learning enthusiasm, unnecessary waste be not only a large amount of abacterial transfusion system and sterile liquids, wasted effectively simultaneously and learnt man-hour, reduced the efficiency of teaching of laboratory.
The utility model content
The inventor is in being engaged in for many years the practice of clinical care or nursing experimental teaching, find that traditional intravenous injection lab exercise mode exists certain defect, through constantly exploring, repeatedly improve, purpose is to propose a kind of venous transfusion experiment and uses transfusion device, can solve preferably the defective that existing venous transfusion exercise mode exists.
Technical solution adopted in the utility model is a kind of venous transfusion experiment of design transfusion device, its structure comprises: infusion bottle pin and protect the pin cap, the transfusion short tube, Murphy type burette, transfusion long tube, transfusion long tube regulator, liquid filter, scalp acupuncture and head protector, wherein, being connected with infusion bottle is provided with the liquid recoil funnel that connects with water tap, and being connected with the transfusion short tube above Murphy type burette is provided with the Y type air injection pipe that connects with syringe nipple.
The utility model in addition after the larger improvement, changes existing venous transfusion exercise mode to existing transfusion device, and the exercise that repeats of intravenous transfusion exhaust and transfusion operation is used.
Utilize the pressure of air or tap water to pass through extension set, the liquid of liquid-transport pipe-line is discharged, or liquid recoiled in the sky infusion bottle, when being pressed into liquid, air in the infusion bottle can discharge, drain through Y type air injection pipe or liquid-transport pipe-line, the repeatable operation exercise to be provided and to experience authentic impression.
1, evacuation of liquid
After an exhaust is finished, folding transfusion short tube, open the regulator of transfusion long tube, open Y type air injection pipe, connect, inject air with large volume injection device nipple and Y type air injection pipe, to drain liquid in the following liquid-transport pipe-line of dropper and dropper, close the long tube regulator, unclamp folding position, can carry out next time exhaust exercise.
2, liquid recoil
When the amount of liquid in the infusion bottle can not satisfy exercise, take off infusion bottle, open transfusion long tube regulator or Y type air injection pipe, the liquid funnel that recoils is docked with water tap, the tap of fetching boiling water, utilize hydraulic pressure that liquid is poured into infusion bottle, the interior air of liquid bottles this moment can be discharged through Y type air injection pipe or liquid-transport pipe-line, drive residual liquid in the most liquid-transport pipe-line; When reaching when needing liquid measure, closed tap, take off funnel, close the long tube regulator, continue the operation practice of exhaust and transfusion.
Use the venous transfusion experiment to use transfusion device, can carry out repeated multiple times doing simulated exercises not needing to change in the situation of transfusion device and infusion bottle, make each learner can both experience the sense of reality of venous transfusion operation at every turn.To improve learning efficiency, grasp operation skill, reduce learning cost, economize on resources, reduce discarded object, protection of the environment has very important meaning; Have simultaneously the exercise of adjusting atmosphere, increase learning interest, excite learner's desire for knowledge and the effect of spirit of exploration, solved well the defective in the existing venous transfusion exercise.
Description of drawings
Fig. 1 represents the utility model venous transfusion experiment structural representation of transfusion device.
Embodiment
In conjunction with the accompanying drawings and embodiments, further specify concrete structure of the present utility model.
The utility model venous transfusion experiment embodiment of transfusion device, referring to Fig. 1, its structure comprises: infusion bottle pin and protect pin cap 1, transfusion short tube 3, Murphy type burette 5, transfusion long tube 7, transfusion long tube regulator 6, liquid filter 8, scalp acupuncture and head protector 9, the liquid recoil funnel 2 that can connect with the water tap mouth that is in parallel and is connected with infusion bottle and arranges with infusion bottle pin 1, the Y type air injection pipe that can connect with syringe nipple that arranges of above Murphy type burette 5, being connected with transfusion short tube 3 and block a shot 4, remove during use and protect the pin cap, the infusion bottle pin is inserted the infusion bottle (not shown).
Sample in venous transfusion laboratory learner simulated training, on probation, satisfactory for result, has reached purpose of design through trial-production, deeply is subjected to liking of learner and teacher.Same applicable bedside practice, the person of learning on the job train use.
