Abstract

An infusion device special-used for operation which can meet all the demands of blood transfusion, fluid infusion, and drug injection is characterized in that an infusion conducting pipe is parallel connected with a burette which is provided with a double filtering screen of blood transfusion and fluid infusion, a capacity mark, and air discharging and drug inlet hole, and then is connected with a blood transfusion pipe with an infusion speed regulator; the last part of the infusion pipe is provided with a tee joint drug injection piece. In the process of infusion, blood enters into the burette by passing trough the blood transfusion pipe, and then enters into the infusion pipe with the infusion speed regulator after being filtered by the blood filtering screen. Doctors can inject drugs through the following three ways: through a drug inlet hole, a drug injection piece, or injecting liquid. The utility model only use one set of infusion device, each link is provided with a strict filtering screen and is equipped with an infusion speed regulator, thereby being able to reduce pollution, avoid the harm of particulates, adjust speed visually and precisely, transfuse blood timely, have low production cost, being easy to produce in the process of infusion, and being suitable for the popularization of clinical using.

Description

The special-purpose blood transfusion and infusion device of performing the operation

Technical field:

The present invention relates to medical transfusion field, be mainly used in the infusion set of infusing and transfusing blood in the operation.

Background technology:

Liquid make-up as required all during operation, what have also needs blood transfusion (comprising the feedback from body blood), and the anaesthetist needs before the art vein of precise speed in vein injection fast and the art to keep medication.Common method is to use earlier transfusion set in the operating room at present, changes the blood exchange transfusion set when needing blood transfusion again; Will directly inject from the remaining needle mouth during administration before Anesthetist's art, when keeping medication medicine directly is added to infusion in the liquid, transfusion speed relies on several number rough calculation.The consequence of bringing thus is a complicated operation, loaded down with trivial details, need plug, change the transfusion device interface repeatedly, increases opportunities for contamination; Because the filtration of general infusion set is poor, make the particulate matter in those medicines enter human body again through transfusion through breaking vial or the extraction of puncture plug into pieces; The anaesthetic infusion velocity is accurate, stable, requirement intuitively because the pulley-type actuator of general infusion set too blindly, roughly, can not reach again; Fortuitous event occurs in the operation still more, when needing promptly a large amount of the blood transfusion, change transfusion device temporarily, often waste time.Therefore, clinical needs a kind of can be intuitively, the infusion liquid of stable and meticulous adjusting, again can urgent, quick, a large amount of when needed blood transfusions; Can make things convenient for anaesthetist's vein to push away medicine fast and keep medication, can reduce the microgranule infringement again; Simple to operate, need not to plug, change transfusion device with regard to the operation special use that can satisfy the operation needs, the invention of this transfusion device is blank at present.

The utility model content:

Technology contents of the present utility model mainly provides a kind of special-purpose blood transfusion and infusion device of operation that can satisfy all requirements of infusing in the operation.Be characterized in: the handy and safe that only both can satisfy interim injection in the operation with the special-purpose blood transfusion and infusion device of a cover operation; Vein keep medication velocity-stabilization, regulate meticulous directly perceived; Transfusion, blood transfusion are changed simple and convenient; Also can reduce the infringement of polluting and preventing microgranule.

It is practical novel mainly by blood, medical liquid container perforator; Transfusion, the blood line of band Infusion clip; The burette that has medicinal liquid, the two drainage screens of blood, aerofluxus medicine-pouring hole, containing mark; The epimere tube for transfusion; The transfusion speed actuator; The hypomere tube for transfusion; The threeway injection part of band medical filtration net; Puncture or remaining needle blank area are connected in series formation in proper order.

After blood, medical liquid container perforator connect transfusion, blood line respectively, the lower end is parallel to be inserted in the burette that has medicinal liquid, the two drainage screens of blood, aerofluxus medicine-pouring hole and containing mark, wherein to be inserted into medical filtration online for transfusion catheter, and it is online that blood line is inserted into blood filtration.Connect burette on the epimere tube for transfusion, connect the transfusion speed actuator downwards.The transfusion speed actuator connects the hypomere tube for transfusion downwards.The hypomere tube for transfusion is provided with the threeway injection part of a band medical filtration net near the end, terminally is puncture or remaining needle joint.

The purpose of this utility model is achieved like this, and during the general surgery transfusion, uses the medical liquid container perforator, liquid enters burette through transfusion catheter, through flowing into the epimere tube for transfusion behind the medical filtration net filtration, through flowing into the hypomere tube for transfusion behind the transfusion speed actuator, after enter the patient vessel.When needing blood transfusion, use the blood vessel perforator, blood enters burette through blood line, through flowing into the epimere tube for transfusion behind the blood filtration net filtration, through flowing into the hypomere tube for transfusion behind the transfusion speed actuator, enters the patient vessel again.During blood transfusion back washing pipe, folder closes blood line, opens transfusion catheter and connects saline and get final product.The approach of the interim medication of doctor has three kinds: 1, add in the liquid container.2, inject burette aerofluxus and dosing hole.3, directly inject through the threeway injection part of band medical filtration net.

Because all operating process are all finished by a cover transfusion device, need not to change, plug, both in time met clinical needs, reduce the chance of polluting again; Blood, medicinal liquid and the interim medicine that injects all pass through strict filtration respectively, just enter the patient vessel; Avoided because take out medicine, make up a prescription, the infringement of the microgranule of puncture and medicinal liquid itself; The configuration of meticulous transfusion speed actuator makes the doctor accomplish accurate grasp the directly perceived to infusion velocity, the dose of operation herb liquid.

This utility model structural design smoothness is complete, simple and practical, though the more structure of function is not loaded down with trivial details, and cost is not high, has promptly improved the level of whole medical treatment and nursing, has alleviated the labor intensity of medical care again, therefore, is suitable for popularizing widely clinically using.
