Disposable convenient type blood-taking deviceTechnical field
The present invention relates to medical supplies, say in detail be a kind of structure simple, easy to operate, rinse normal saline consumption few, effectively can reduce intensive care patient, the patient such as super preterm low-birthweight infant of department of pediatrics Intensive Care Therapy to bring the disposable convenient type blood-taking device of a series of complication such as anoxia because of normal saline to the dilution of blood.
Background technology
We know, for the super preterm low-birthweight infant of intensive care unit (ICU) patient, long-term inpatients patient (comprising old man and adult), especially department of pediatrics intensive care unit (NICU), medical personnel often need taken at regular intervals blood sample to detect to them, and sometimes needing repeatedly took a blood sample in one day detects.
Existing conventional blood collection device comprises blood sampling valve, useless blood collection valve, flushing valve, calparine cap, injector for collecting blood, useless parts such as blood collection syringe, irrigating syringe etc., and blood sampling valve and useless blood collection valve are three-way valve, etc., make whole device structure complicated, cost is higher.In the processes such as its useless blood collection, blood sampling, blood recovery, cleaning, aerofluxus, repeatedly need control blood sampling valve, useless blood gathers valve, flushing valve etc., make complex operation complicated; , also there is thorn by mistake and cause the hidden danger of cross infection in medical worker's multi-pass operation syringe.What is more important, large (under normal circumstances in order to the blood in pipeline being re-entered flushing fluid required in patient body after blood sampling, irrigating syringe slow infusion 0.8ml flushing liquor with by the blood recovery in pipeline to patient, and then with the abundant flushing line of new flushing liquor of 0.7ml to 1ml and before patient itself connect the pipeline of remaining needle, guarantee the remaining blood that the tip of remaining needle is not residual), and these flushing liquors (normal saline) can bring a series of chain risks such as anoxia to the dilution of blood, as may to super preterm low-birthweight infant, baby or the poor old man of body constitution cause ventricular hemorrhage (IVH), and then the probability causing infant to suffer from cerebral palsy in the future significantly increases, bringing out of multiple cardiovascular and cerebrovascular disease etc. is caused to old people, medical-risk is increased.
Summary of the invention
An object of the present invention, be solve above-mentioned the deficiencies in the prior art, provide a kind of structure simple, with low cost, fast simple to operation, required flushing fluid is few, avoids the disposable convenient type blood-taking device bringing out patient's other diseases.
Object two of the present invention, is to provide one and avoids stabbing medical personnel, with anti-cross infection, guarantees the disposable convenient type blood-taking device of medical personnel's health.
For realizing above-mentioned two objects, the technical scheme that solution of the present invention adopts is as follows:
Disposable convenient type blood-taking device, be provided with needle stand, needle stand is provided with connection needle tubing, it is characterized in that being provided with on rear side of needle stand and the Y-type three way type joint being connected needle tubing and being communicated with, Y-type three way type joint is connected to fine blood taking tube and fine useless blood vessel, fine blood taking tube and fine useless blood vessel rear end are connected with female Luer, and fine blood taking tube and fine useless blood vessel are provided with blood sampling clamp and useless blood folder, and female Luer is provided with waterproof and breathable plug.
The connection needle tubing of this blood-taking device is provided with protective sleeve, plays a protective role to connection needle tubing.
This blood-taking device in use, is closed blood sampling clamp and useless blood folder, is connected in the female Luer of fine useless blood vessel rear end by the syringe collecting useless blood; The syringe of blood sampling is connected in the female Luer of fine blood taking tube rear end, the connection needle tubing of this blood-taking device is inserted in T-shaped three way cock one end of venous detaining needle, be connected with venous detaining needle.Open useless blood folder, keep the syringe rear end of collecting useless blood to raise up about 30 degree angles, after gathering useless blood 0.5ml, close useless blood and press from both sides; Open blood sampling clamp, after using injector for collecting blood to gather blood to requirement, close blood sampling; Open useless blood folder and will give up blood with 1ml/30sec(every 30 seconds 1 milliliter) speed slowly inject back in patient body, the closedown blood that gives up presss from both sides, and take off this blood-taking device, blood sampling completes.Finally in the T-shaped three way cock of venous detaining needle, inject 0.3-0.5ml flushing liquor with flushing syringe, indwelling needle catheter and T connector can be cleaned.So far, blood sampling and flushing all complete.
Structure of the present invention is simple, with low cost, simple, convenient, and required flushing fluid is few, avoids bringing out patient's other diseases, achieves first object of the present invention.
Connection needle tubing 2 front end described in this blood-taking device is concordant end, to avoid in use procedure, because of sharp needle pricks medical personnel, achieving second object of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Disposable convenient type blood-taking device as shown in Figure 1, be provided with needle stand 3, needle stand 3 is provided with and connects needle tubing 2, be provided with on rear side of needle stand 3 and the Y-type three way type joint 4 being connected needle tubing 2 and being communicated with, Y-type three way type joint 4 is connected to fine blood taking tube 5 and fine useless blood vessel 10, fine blood taking tube 5 and fine useless blood vessel 10 rear end are connected to female Luer 8-1 and 8, and fine blood taking tube 5 and fine useless blood vessel 10 are provided with blood sampling clamp 6 and useless blood folder 7, and female Luer 8 and 8-1 are provided with waterproof and breathable plug 9 and 9-1.The front end connecting needle tubing 2 is concordant end, avoids in use procedure because of sharp needle pricks medical personnel.Connect needle tubing 2 and be provided with protective sleeve, connection needle tubing is played a protective role.
The present invention in use, inserting in T-shaped three way cock one end of venous detaining needle by connecting needle tubing, being connected with venous detaining needle, open blood sampling clamp and useless blood folder, blood, through connecting needle tubing, Y-type three way type joint, fine blood taking tube and fine useless vessel flow to female Luer place, is stopped by waterproof and breathable plug; Close blood sampling clamp and useless blood folder, extract waterproof and breathable plug, the syringe collecting useless blood is connected in the female Luer of fine useless blood vessel rear end, the syringe of blood sampling is connected in the female Luer of fine blood taking tube rear end; Keep the syringe rear end of collecting useless blood to raise up about 30 degree angles, open useless blood folder and gather useless blood 0.5ml, then close useless blood and press from both sides; Open blood sampling clamp, use injector for collecting blood to gather blood to requirement, close blood sampling clamp; Open useless blood folder and will give up blood with 1ml/30sec(every 30 seconds 1 milliliter) speed slowly inject back in patient body, the closedown blood that gives up presss from both sides, and take off disposable convenient type blood-taking device of the present invention, blood sampling completes.Finally use flushing syringe to inject 0.3-0.5ml flushing liquor in the T-shaped three way cock of venous detaining needle, indwelling needle catheter and T connector can be cleaned.So far, blood sampling and flushing all complete.Structure of the present invention is simple, with low cost, simple to operation, and required flushing fluid is few, can effectively avoid bringing out patient's other diseases, provides available protecting to medical personnel simultaneously.
