Abstract
The invention belongs to medical equipment and relates to a disposable safety infusion 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), an infusion flexible tube (7) and a Luer taper (8). The disposable safety infusion needle is used for medical gravity or pressure transfusions 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 used for the upper gravity of medical treatment, pressure transfusion, is used for simultaneously the anti-accidental needle sticks of nursing staff and hinders.
Background technology
The most frequently used disposable infusion pin of domestic hospitals is non-safety mostly now, and show: 1, infusion tube 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 being when pulling out pin behind the patient infusion or is processing in the transfusion needle process of using 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; safe infusion 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 transfusion needle easy to use; it will possess: sharp keen analgic syringe needle; comfortable ultra-thin needle tubing; the safe infusion hose materials; the safety guard that has anti-accidental needle sticks to hinder; the inventor has invented disposable use safety transfusion needle for this reason; be patient's gravity; pressure dosing provides desirable safe infusion device, and the protection nursing staff is not accidentally injured by pin.
Summary of the invention
In order to overcome the deficiency of existing transfusion needle; the applicant has invented a kind of new equipment: disposable use safety transfusion needle; its advantage is: sharp keen analgic syringe needle; the needle tubing of comfortable thin-walled; the safe infusion hose materials; 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), infusion tube (7), female Luer (8) 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 the safety transfusion 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: when needing to pull out pin behind the infusion-completed; 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) infusion tube pressure can tolerate 1 normal atmosphere, can be used for the transfusion of gravity and pressure.

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), infusion tube (7), female Luer (8) 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 the safety transfusion 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: when needing to pull out pin behind the infusion-completed; 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.
Infusion tube 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, be used for gravity infusion, pressure transfusion, comprise the use of infusion pump.
Above-mentioned disposable use safety transfusion 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.
Above-mentioned drawings and Examples only are used for explanation the present invention, to protection scope of the present invention, do not constitute any limitation.
