Abstract
The utility model discloses an automatic blood taking needle which comprises a case, a blood taking needle and a blood taking needle sleeve. The automatic blood taking needle is characterized in that the case consists of a left half-case and a right half-case, an 'L'-shaped push rod is processed on the left half-case, and a push plate is processed on the right half-case; the blood taking needle is vertically inserted into and fixed in a sliding block; a wedge-shaped convex slot which is propped by the lower end of the push plate is processed on the right side wall of the sliding block; and the sliding block is provided with a spring and is arranged between two cross bars, thus guaranteeing the sliding block to move up and down vertically without shifting. The automatic blood taking needle can puncture the surface texture of skin on a fingertip under the condition that a patient is not aware of the puncture, and the patient does not feel painful at the moment, and simultaneously, the blood taking needle and the sliding block rapidly retract downwards into the case under the tensile force of the spring, thus not puncturing the skin of the patient again. The blood taking needle has the advantages of being capable of automatically, rapidly and snugly puncturing the surface texture of skin on fingertips, causing no pain at the moment, being safe and reliable, and having convenient use.
Description
Technical field
This utility model relates to medical apparatus and instruments, especially relates to a kind of self-action blood taking needle.
Background technology
The doctor will just can accurately diagnose according to the blood sample report often in the disease of judging patient.Generally, blood sampling all is to puncture patient's the middle finger tip or the surface skin member of forefinger tip by medical personnel with the blood taking needle that is similar to draw point, then the blood on middle finger or the forefinger is extruded, and finishes blood sampling.This blood taking needle bodily form is bigger, and medical personnel's action is very obvious again, and by medical personnel's dynamics control, patient fears that comparatively pain is very obvious to the depth of wound fully, particularly to child and teenager, generally all has and fears and resentment.
Summary of the invention
The purpose of this utility model is to provide a kind of surface skin member, moment self-action blood taking needle painless, safe and reliable, easy to use that can puncture finger tip automatically, fast, snugly.
The purpose of this utility model is achieved in that a kind of self-action blood taking needle, comprise housing, blood taking needle and blood sampling needle guard, feature is that housing is made up of a left side half housing and right half housing that are fastened togather by projection and groove, on the left side wall of a left side half housing, be processed with push-rod hole, in push-rod hole, be processed with rubber-like " L " shape push rod, the riser upper end of " L " shape push rod is connected as a single entity with the left side wall of left half housing, the lower end of the riser of " L " shape push rod is exposed to outside the left side wall of left half housing, identical and the cross bar that separate of two shapes of push rod stretches in the housing, be processed with the push pedal hole on the right side wall of the right side half housing, the right side wall that is processed with upper end and right half housing in the push pedal hole is connected as a single entity, the lower end is unsettled, slope inwardly and the rubber-like push pedal; The middle lower end of blood taking needle vertically is inserted and secured in the sliding shoe, on the right side wall of sliding shoe, be processed with the wedge shape projecting slot that allows the push pedal lower end withstand, the lower end of spring is enclosed within on the spring cage plate of lower end in left half housing, and the upper end of spring is enclosed within on the projection of sliding shoe bottom; Sliding shoe is positioned between two cross bars, thereby guarantees that sliding shoe can be vertically, and non-migration is processed with at the top of housing and allows blood taking needle eject and left half housing and right half housing respectively account for the blood sampling hole of semicircle.
The handle shape of blood sampling needle guard is heart-shaped.
This utility model is made up of housing, blood taking needle, sliding shoe, spring and blood sampling needle guard, before the use, pushes the blood sampling needle guard downwards, the blood sampling needle guard promotes sliding shoe and moves down along two cross bars, the compression spring slips in the wedge shape projecting slot until push pedal, and push pedal is pushed down sliding shoe and do not allowed and move on it.During use, take out the blood sampling needle guard, be placed on the blood sampling hole after the finger tip sterilization with patient, cover the blood sampling hole, medical personnel hold housing, firmly inwardly push push rod, cross bar on the push rod will outwards push the lower end of push pedal, make push pedal break away from the wedge shape projecting slot, the spring jack-up sliding shoe that will make progress makes sliding shoe move on fast along two cross bars, blood taking needle is upward through the blood sampling hole, very snugly, under the situation that patient has no to discover, puncture the surface skin member of finger tip, and patient moment without any pain, thereby reached the purpose of blood sampling, meanwhile, blood taking needle and sliding shoe in the downward fast again withdrawal housing, can not cause puncturing patient skin once more under the pulling force of spring, thereby as safe as a house reliable.Therefore, the utlity model has surface skin member, the moment advantage painless, safe and reliable, easy to use that can puncture finger tip automatically, fast, snugly, is a kind of self-action blood taking needle.
