Abstract
The utility model discloses a safe blood taking needle instrument structure comprises a pipe body, a compression element, a first spring element, a needle instrument, a second spring element and a cover element, wherein the compression element forms a plurality of resisting columns and the resisting columns resists a needle base of the needle instrument so as to form a resisting part with an oblique surface; by means of a sliding way and a side wall in the inner pipe walls of a pipe body, the resisting columns can clamp or release the needle instrument through slippage, and then through the first spring element and the second spring element at the front end and the rear end of the needle instrument, thus the needle instrument can be stored into the pipe body after being sprung out, and thus the safe blood taking needle instrument structure can be used by users safely with small applying force.
Description
Technical field
This utility model relates to a kind of safety blood taking needle set structure, refers to a kind of blood sampling needle set of clip mode fixing needle set especially.
Background technology
Medical system sound, can have to improve and treat and measure such as protection when running into sick or injured the grade for the common people, more can provide the common people different medical informations.
Yet; In various diseases, wherein the patient of diabetes takes normal blood sampling and detects the glycemic index in the blood, and cooperates medicine and diet to be effectively controlled; And the structure of hemostix ejects needle set with rotation mode or side buckle mode; This needle set is comparatively complicated in assembling, and in use to go up needing to push just so that needle set ejects with great more, so is prone to let the user band mood frightened or that fear and operates hemostix.
Edge is the disappearance of known blood collection device for a change; Provide assembler to have simpler and easy assembling fast and user that the mode of manipulating is more easily arranged, the applicant proposes a kind of safety blood taking needle set structure, and this blood taking needle is combined by body, pressing piece, spring part, needle set, second spring part and cover piece; Wherein this pressing piece extends to form several in an end and resists post; And in resisting column end formation inclined-plane, the needle stand both sides of this needle set form the resistance portion on tool inclined-plane in addition, and oppress by the resistance post of pressing piece and the inner tubal wall of body the assembling back; Let the inclined-plane that resists post one end and the resistance portion of the needle stand of the needle set also static needle set of conflicting each other; Inwardly push via pressing piece, make and resist post and slide onto the end through slideway and make this end break away from slideway and unclasp needle set, again via first and second spring part of needle set front and back end; Make needle set eject the preservation of taking in of blood sampling and needle set, let user that use safer and that the application of force is little is arranged.
Summary of the invention
This utility model technical problem to be solved is: to the deficiency of above-mentioned prior art, provide a kind of can simpler and easy assembling fast and user the safety blood taking needle set structure of manipulating mode is more easily arranged.
In order to solve the problems of the technologies described above; The technical scheme that this utility model adopted is: a kind of safety blood taking needle set structure; Comprise body, pressing piece, first spring part, needle set, second spring part and cover piece; This needle set has needle stand, protecting cover and needle body, and this protecting cover is corresponding to the needle stand end, and this needle body is arranged at this needle stand center; Be characterized in: the internal ring of said body encloses and forms slideway and sidewall; This pressing piece is arranged at body inside, has holding part, and extends several resistance posts that the end is provided with the tool inclined plane; This first spring part is arranged at the holding part of this pressing piece; This needle set polyphone is arranged at first spring part, pressing piece is inner with body, and the needle stand of this needle set has symmetric projection and resistance portion, and end formation pedestal, and this second spring part is arranged between the pedestal of needle stand of needle set; This cover piece has holding part corresponding to second spring part, and connects second spring part, needle set, first spring part and pressing piece, is covered on body one end;
Wherein, When applying a pressure in pressing piece; The slideway that makes the end of the resistance post of this pressing piece prolong body slides the end of to and flicks up and down, makes the resistance portion disengaging of the inclined-plane that resists column end and the needle stand of needle set, and this needle set is forward released by second spring part; Make needle body pass body one end, again by first spring part with the reverse needle set that pushes back.
Said body one end forms the stopper section.
The stopper section in body is resisted in said pressing piece one end.
The projection of said needle set supplies first spring part to resist.
The resistance portion of the needle stand of said needle set supplies the inclined-plane correspondence of the resistance post of pressing piece.
The another kind of technical scheme that this utility model adopts is: a kind of safety blood taking needle set structure; Comprise body, pressing piece, first spring part, needle set, second spring part and cover piece; This needle set has needle stand, protecting cover and needle body; This protecting cover is corresponding to the needle stand end, and this needle body is arranged at this needle stand center; Be characterized in: the internal ring of said body encloses and forms slideway and sidewall; This pressing piece is arranged at body inside, has holding part, and extends several resistance posts that the end is provided with the tool inclined plane; This first spring part is arranged at the holding part of pressing piece; It is inner that this needle set polyphone is arranged at first spring part, pressing piece and body, and the needle stand of this needle set has symmetric projection and resistance portion, and an end forms pedestal; This cover piece has holding part corresponding to second spring part, and connects second spring part, needle set, first spring part and pressing piece, is covered on body one end;
Wherein, When applying a pressure in pressing piece; The slideway that makes the end of the resistance post of this pressing piece prolong body slides the end of to and flicks up and down, makes the resistance portion disengaging of the inclined-plane that resists column end and the needle stand of needle set, and this needle set is forward released by second spring part; Make needle body pass body one end, again by second spring part with the reverse needle set that retracts.
So; This pressing piece forms several and resists post and resist the resistance portion that between the needle stand of this needle set, forms the tool inclined-plane; By slideway between the inner tubal wall of body and sidewall, make resist post through slippage can to the needle set clamping with unclasp, again by first and second spring part of needle set front and back end; Needle set can be stored between body after ejecting, let user that use safer and that the application of force is little is arranged.
