Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a blood sampling suit of avoiding medical staff's damage.
Background
The collection of arterial blood and the collection of effusion are common, simple and necessary operating skills in clinical work. With the aging population and the increasing number of patients with lung diseases, more and more patients need to be admitted for blood gas analysis and liquid extraction. The most easily-occurred medical injury of medical workers in the blood sampling and liquid drawing processes is puncture injury caused by a needle head, and serious infection diseases of the medical workers can be caused. Poor handling consumables can easily cause repeated acupuncture on a patient, resulting in partial skin bruise, blood stasis, red swelling and infection of the patient. The blood gas needle used clinically at present is provided with a fussy shell protection device, is easy to fall off and is a simple needle tube without a protection device.
The existing blood sampling needle tube can not well avoid medical staff from being punctured, can not quickly and effectively complete the operation process, has thick and heavy protective layers, is easy to drop to influence the operation, reduces the success rate, wastes more consumables and aggravates the injury of the vascular skin of a patient.
In addition, the technique of puncture catheterization mainly depends on the hand feeling and clinical experience of an operator, and is a great challenge for students who just enter clinical practice. The operator can not judge whether the outer sleeve is in the blood vessel immediately when the blood is seen during the puncture, and at the moment, the outer sleeve is immediately placed or the needle stem is pressed down to continue to insert the needle for 1-2mm and then is placed in the outer sleeve, so the judgment is particularly difficult. Because the puncture is performed by touching the blind puncture, the angle of the puncture needle insertion and the radial artery form an included angle easily, the side wall of the artery can be punctured by 1-2mm, the tail part of the needle is filled with blood, an operator cannot accurately judge the position of the needle point, and the tube placement failure is easily caused.
If the first catheter placement fails, the radial artery can cause the subsequent puncture catheter placement to be more difficult due to the stimulation spasm or local hematoma, and meanwhile, great pain is brought to the patient.
To above defect, the inventor has designed the utility model relates to an avoid blood sampling suit of medical staff damage, more current blood sampling needle tubing economizes the consumptive material more, operates more conveniently, reduces hospital pollution and medical source injury above all.
