Description

Disposable painless hemostix

This utility model relates to medical instruments field.

At present, the disposable blood sampling blade or the pin of medical worker's use are with holding blade, finger being punctured.This method weak point is that the degree of depth of stinging is wayward, and the patient has obvious pain.

The purpose of this utility model is exactly the deficiency at above-mentioned blood sampling blade, and a kind of disposable painless hemostix is provided, and it is just right to control the degree of depth of thrusting finger, and speed is fast, the painless feel of patient.

Structure of the present utility model is: be made up of disposable blood sampling blade or pin and blood sampling folder, the blood sampling folder is by housing (1), pull bar (2), pull-rod spring (3), pushing ram (4), pushing ram spring (5), banking stop (6), plate button (8) and blade folder (9) are formed, housing (2) is opened foraminous tube for two ends, pull bar (2) is placed in the tube, there is pull handle one end to be exposed at outside the tube, pull-rod spring is through on the pull bar (2), put into tube, pushing ram also is placed in the tube, an end that has pushing ram to be hit handle (7) is put into tube, the other end exposes outside the tube, link to each other with blood sampling folder (9), pushing ram spring (5) is through on the pushing ram (4), puts into tube, pushing ram spring (5) is positioned at an end that is hit handle (7) and is fixed on the pushing ram (4), other end top is toward the end of tube, and banking stop (6) is fixed on an inwall, banking stop and hit the 1-4mm that is spaced apart between the handle, plate button (8) is fixed on the housing, and blood sampling blade or pin (10) are clipped on the blade folder (9).

Advantage of the present utility model is: the one, and the degree of depth that blade thrusts the human body can be controlled; The 2nd, to withdraw from human body speed fast because blade thrusts, in 0.5 second, finish, so the almost imperceptible pain of patient; The 3rd, disposable blade is clipped on the blade folder, therefore, finish blood sampling after, press the plate button, blade or pin come off automatically and discard, the blood sampling folder is reusable; The 4th, the staff need not directly touch blood sampling blade or pin, prevents to pollute and cross infection.

Operation principle: when pull bar (2) by plate button (8) when blocking, pull-rod spring (3) is energy storage thereupon, with the close position that needs blood sampling of the blade of this hemostix, press the plate button, pull bar hits pushing ram rapidly and is hit handle (7) under the effect of spring force, pushing ram is advanced rapidly, blade thrusts the human body, because the effect of banking stop, when pushing ram was hit handle and touches banking stop (6), pushing ram advanced and promptly stops, under sting the degree of depth can only be between 1-4mm, specifically decide,, withdraw from rapidly after making blade lunge the human body simultaneously because the effect of pushing ram spring (5) on the banking stop and the spacing of being hit between the handle.

Accompanying drawing 1 is this utility model structural representation.

Embodiment:

Housing is with metal or plastic production, and for the ease of installing, housing is divided into two parts, middlely use screwed connection, and the connected mode that all parts are partly narrated by said structure is assembled, and banking stop and the spacing of being hit between the handle are 3mm.
