Abstract
The invention belongs to medical equipment and relates to a disposable safety blood-sampling needle mainly comprising a protective cover (1), a needle tube (2), a needle holder (3), needle wings (4), a wing guard (5), a lock (6), a flexible tube (7), a Luer taper (8), and a stopper piercing needle (9). The disposable safety blood-sampling needle is used for sampling blood during blood detection and protecting medical staff from accidental injuries by the needle.
Description
Technical field
The invention belongs to technical field of medical instruments, the whole sterilization of this product, disposable use is taken a blood sample when being used for blood testing, is used for simultaneously the anti-accidental needle sticks of nursing staff and hinders.
Background technology
The most frequently used disposable lancet of domestic hospitals is non-safety mostly now, and show: 1, blood sampling pipe is dangerous, all is the PVC material mostly, contains certain plasticiser, can bring certain genotoxic potential to patient and nursing staff; 2; structural design is dangerous; the nursing staff is when pulling out pin after the patient blood sampling or processing in the blood taking needle process of use and understanding often by accidental needle sticks; especially the user of pin is hepatitis patient; the AIDS patient; the pin accidental injury can cause the nursing staff to infect virus; serious threat nursing staff's body and mind and life; reinforcement along with health care consciousness; safety blood taking has enjoyed medical personnel and patient's generally attention; therefore clinically in the urgent need to a kind of material safety; structure is advanced; safety type blood-taking needle easy to use; it will possess: sharp keen analgic syringe needle; comfortable ultra-thin needle tubing; the safe transfusion hose materials; the safety guard that has anti-accidental needle sticks to hinder, the inventor has invented disposable use safety type blood-taking needle for this reason, for patient and medical personnel provide desirable safety blood taking device.
Summary of the invention
In order to overcome the deficiency of existing blood taking needle; the applicant has invented a kind of new equipment: disposable use safety type blood-taking needle; its advantage is: sharp keen analgic syringe needle; the needle tubing of comfortable thin-walled; safe material pipeline; the safety guard that has anti-accidental needle sticks to hinder; its structure mainly by protective sleeve (1), needle tubing (2), needle stand (3), the pin wing (4), shield with one's own body cover (5), snap close (6), flexible pipe (7), female Luer (8), bottle cork needle (9) and form, specific features is as follows:
1) syringe needle of needle tubing can adopt respectively monocline face, double inclined plane, three ramp structures, and the needle tubing pipe is provided with snap close outward.
2) shield with one's own body in the cover cover and be provided with snap close, shield with one's own body the cover afterbody with locked groove.
3) needle stand is provided with snap close, and before safety type blood-taking needle used, needle stand was locked in by snap close on the locked groove of shielding with one's own body the cover afterbody, formed integral type and was connected and fixed mode.
4) safety guard by needle tubing, needle stand, shield with one's own body cover, snap close forms jointly; its using method: take a blood sample when needing to pull out pin after complete; open snap close on the needle stand by being affectedly bashful needle stand; separate needle stand and shield with one's own body cover; continue to pull out in the process of pin, the needle tubing backhaul when shielding with one's own body the precalculated position of cover, on the needle tubing predetermined snap close with shield with one's own body snap close predetermined in the cover cover and can excite and lock together; expendable locked, needle point and needle tubing are taken in to be fixed on fully and are shielded with one's own body in the cover.
5) hose pressure can tolerate 1 normal atmosphere, can be used for venous blood collection, arterial blood drawing.

The specific embodiment
Particularly, the present invention mainly by protective sleeve (1), needle tubing (2), needle stand (3), the pin wing (4), shield with one's own body cover (5), snap close (6), flexible pipe (7), female Luer (8), bottle cork needle (9) and form.
The primary raw material that the present invention adopts: rustless steel, Merlon, ABS resin etc., the first-selected non-PVC material of infusion tube such as polyurethane etc., secondly selection does not contain the PVC material of plasticiser DEHP.
Concrete production by techniques such as pin processed, injection moulding, trombone slide, hot-pressing processing, ultra-sonic welded realized.
Needle tubing among the present invention is one of parts of core key: the structure that requires needle tubing: syringe needle can adopt respectively monocline face, double inclined plane, three ramp structures, and the needle tubing pipe is provided with snap close outward.
Among the present invention shielding with one's own body cover be the core key parts two: require to shield with one's own body in the cover cover and be provided with snap close, shield with one's own body the cover afterbody with locked groove.
Needle stand among the present invention be the core key parts three: require needle stand to be provided with snap close, before safety type blood-taking needle used, needle stand was locked in by snap close on the locked groove of shielding with one's own body the cover afterbody, formed integral type and was connected and fixed mode.
Safety guard among the present invention be the core key parts four: require safety guard by needle tubing, needle stand, shield with one's own body cover, snap close forms jointly; its using method: take a blood sample when needing to pull out pin after complete; open snap close on the needle stand by being affectedly bashful needle stand; separate needle stand and shield with one's own body cover; continue to pull out in the process of pin; the needle tubing backhaul is when shielding with one's own body the precalculated position of cover; on the needle tubing predetermined snap close with shield with one's own body snap close predetermined in the cover cover and can excite and lock together; expendable locked, needle point and needle tubing are taken in to be fixed on fully and are shielded with one's own body in the cover.
Flexible pipe among the present invention is five of core key part, require to be water white transparency, material adopts non-PVC material such as polyurethane etc., also can adopt the PVC material that does not contain plasticiser DEHP, its proof pressure can tolerate 1 normal atmosphere, is used for venous blood collection, arterial blood drawing.
Above-mentioned disposable use safety type blood-taking needle is by after the entire package, through 60Coradiation sterilization or epoxyethane fumigation sterilization.Disposable use, not recyclable use is reused after can not sterilizing.
