Abstract
The utility model relates to a safety infusion needle which comprises an infusion needle with wings and a safety sleeve. An infusion tube is connected to the tail of the infusion needle. The infusion needle is slidably disposed in the safety sleeve. An infusion needle locking mechanism is disposed on the safety sleeve. The tail wall of the safety sleeve is provided with a notch forming an infusion tube bayonet which is smaller than the infusion tube in diameter. The infusion tube can only be clamped in by squeezing. The notch on the tail wall of the safety sleeve forms the infusion tube bayonet and is smaller than the infusion tube in diameter. The infusion tube is retracted into the safety sleeve after use. The tail infusion tube is clamped in the bayonet by the action of elasticity of the infusion tube. The infusion tube can be limited in the safety sleeve very reliably.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of safety transfusion needle.
Background technology
According to relevant statistics, China uses the most general country of intravenous injection, and have a large amount of used disposable infusion needles to go out of use every year in the hospital.In order to reclaim useful metal and to avoid contaminated environment, used disposable infusion needle need to be recycled, in order to prevent in removal process, stabbing the related personnel, cause injury and superinfection, existing transfusion needle can be furnished with safe sleeve pipe, described safe sleeve pipe both sides are provided with axial slide, described transfusion needle is slidably disposed in the safe sleeve pipe, the pin wing of described transfusion needle exposes from chute, in the position near the chute tail end, the chute edge can be provided with the projection of a right angled triangle so that the chute at this place narrows down, and the block that forms simultaneously a retaining consists of the transfusion needle latching device.The transfusion needle retraction pinches the smooth groove of the pin wing after disposable infusion needle uses the pin wing is pulled through block prevention pin wing reverse slide, so that in safe sleeve pipe, can avoid stabbing the related personnel.Because chute is relatively long, safe sleeve pipe adopts plastics to make usually, has certain elasticity, and the latching device of therefore existing safety transfusion needle transfusion needle still exists block can not block reliably the problem of the pin wing.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and a kind of more safe and reliable safety transfusion needle is provided.
In order to achieve the above object, the utility model discloses a kind of safety transfusion needle, comprise the transfusion needle and the safe sleeve pipe that are provided with the pin wing, described transfusion needle afterbody is connected with tube for transfusion, described transfusion needle is slidably disposed in the safe sleeve pipe, it is characterized in that: the tail end tube wall of described safe sleeve pipe is provided with the tube for transfusion bayonet socket that is made of breach, and described bayonet socket is less than the diameter of tube for transfusion, the tube for transfusion extruding just can must be snapped in.
Compared with prior art, the tail end tube wall of the safe sleeve pipe of safety transfusion needle is provided with the tube for transfusion bayonet socket that is made of breach, and the size of bayonet socket is less than the tube for transfusion diameter,, the tube for transfusion extruding just can must be snapped in.After transfusion needle uses, be retracted into transfusion needle in the safe sleeve pipe after, utilize tube for transfusion to have certain elastic characteristics the tube for transfusion of its tail end be stuck in the bayonet socket, can very reliably transfusion needle be limited in the safe sleeve pipe.
Below in conjunction with specification drawings and specific embodiments this utility model is done further introduction.
