Description
Technical field
This utility model belongs to medical blood taking instrument field, be specifically related to a kind of only for nonrecoverable disposable before some trigger-type safety self-destruct blood-taking device, can be used for preventing the secondary utilization of disposable automatic blood-taking device.
Background technology
Often need carry out the blood sample collection program during blood test; Carry out blood sampling at present and often adopt blood collection needle pin or disposable blood taking needle.Aspects such as disposable blood taking needle is preventing patient or crowd's mutual infection, and is easy to use have bigger advantage, and are comparatively general in clinical use at present, especially to the sampling of taking a blood sample such as special population such as child.Only needing when automatic blood-taking needle uses the skin that blood taking needle be pressed close to user taken a blood sample gets final product, and can carry out one-handed performance.Adopt the automatic blood-taking needle blood sampling on average to shorten 1.5min, improved work efficiency, alleviated patient's psychological burden than blood collection needle method blood sampling time.And automatic blood-taking needle is small and exquisite, convenient, is easy to carry about with one, the convenient check of taking a blood sample under various environment.
Because these advantages of automatic blood-taking needle, the employing of automatic blood-taking needle more and more widely in the actual life.The form of disposable blood taking needle is varied at present, this class blood taking needle is generally formed by housing, blood taking needle, spring and guide frame, general spring is arranged on the blood taking needle rear end, described blood taking needle generally adopts the position limiting structure clamping to make blood taking needle rear end spring keep compressive state and accumulation of energy, so just form the ejection mechanism of blood taking needle, guiding mechanism generally is provided with gathering sill by the housing inboard and guide pad cooperation formation shooting guide frame is set on the blood taking needle nook closing member.
Chinese patent ZL03221437.5 disclosed a kind of self-locking type disposable safe automatic blood-taking needle in the prior art on June 9th, 2004, comprise shell, end cap, nook closing member, spring, push away and send out device and block, a pair of elastic claw is arranged in shell on the end cap, this elastic claw utilize grab and chucking power with the nook closing member both sides pick up the ears block; Push away and send out a device and adopt the inclined-plane to meet two elastic claws head-on on the one hand to force it to break off relations, cooperates formation to shoot guide frame by the gathering sill of long foot inboard with guide pad on the nook closing member on the other hand, this guide frame and elasticity clamping structure are the decussation layout; Setly on the nook closing member forming a structure that prevents horizontal reset on the nook closing member with the grab bottom after the shooting from locking face.Yet, find that in use because being equipped with of guide pad and gathering sill makes blood taking needle can be subjected to the influence of frictional force in ejection travel, effect is launched in influence; In addition, the direction of ejection of blood taking needle is not a direction with gathering sill and guide pad when consistent when the rear end spring discharges, and can cause that blood taking needle is stuck can not to be used, and even more serious consequence might cause the injury to quilt blood sampling person; In addition, block that adopts in this patent and blood taking needle nook closing member carry out nature and fasten, and its joint portion with nook closing member is not sealed and matched, and cause before the blood sampling operation this blood taking needle easily by germ contamination, the result that the influence blood sampling is checked.The present invention comes therefrom.
Summary of the invention
This utility model purpose be to provide a kind of disposable before some trigger-type safety self-destruct blood-taking device, solved in the prior art blood-taking device guiding mechanism the unreasonable blood taking needle problems such as poor effect of can not taking a blood sample or take a blood sample that cause be set.
In order to solve these problems in the prior art, the technical scheme that this utility model provides is as follows:
A kind of disposable preceding some trigger-type safety self-destruct blood-taking device, comprise clamping device and blood taking needle, described blood taking needle both sides are the clamping device clamping, it is characterized in that described blood taking needle rear end is provided with spring and is connected with clamping device, described clamping device clamping blood taking needle and compress spring energy-storage; Described clamping device front end is provided with clamping device and cooperates the deploying device that discharges blood taking needle, and described deploying device inner hollow forms the ejection chamber for the blood taking needle ejection operation; Ejection chamber matched in clearance in described blood taking needle and the deploying device.
