Description

A kind of blood-taking device of needle outlet band buffer unit
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of blood-taking device of needle outlet band buffer unit.
Background technology
Use the blood taking needle skin puncture, the behavior of obtaining blood sample remains the standard method of foreseeable future, because take the additive method of blood sample not yet to prove its superiority (for example using laser technology).Avoid the additive method of complete otch also not yet to obtain the approval (for example Wicresoft's Dynamic Blood Glucose Monitoring) in market, perhaps not yet represent its technical feasibility (for example Woundless blood sugar monitoring).
But when using blood-taking device that the patient is taken a blood sample, the pain that patient body produces can cause the patient to be unwilling to take a blood sample, and is unfavorable for the popularization of blood collecting technology.
Pain during blood sampling is divided into: spontaneous pain (pain of feeling immediately during blood sampling) and remaining rear pain (rest pains after the blood sampling after a few minutes or several hours).
Below several factors determine the pain of blood sampling operation: paracentesis depth, puncture speed, integral body is thrust track, the blood taking needle size, skin surface, skin is fixed, and finger tip blood sampling location positioning; Most manufacturer obtains more high accuracy that sizable progress for example grips specification, tips quality, effectively polishing and the top layer design that slips into smoothly skin in the quality of production of blood taking needle, but also occurs in the market effectively blood sampling product in the control of thrusting track for integral body.
What traditional machinery blood sampling operating equipment used is that rectilinear motion drives, and driving mechanism often is made of a pair of spring, and when holding up, then the user Compress Spring pins the button relieving mechanism, and for the first time springing makes blood taking needle thrust skin; Reclaim for the second time " in the shell " that shield in the blood taking needle auto levelizer, the vertical direction of the direction of advance of blood taking needle and main motion vector is not to be controlled exactly, and this can cause series of problems:
The inaccuracy of motion terminating point;
The hard stop of the degree of depth (swivel point) that punctures, this is a major reason that causes spontaneous pain;
The vibration path causes coarse wound passage, and this is a major reason that causes remaining pain;
Uncontrolled rate of withdraw causes slowly wound suture and hemorrhage afterwards);
" swing " of mass motion (remaining pain, lasting wound, and scar);
The resilience of mechanism causes unplanned again blood sampling operation.
Begin to eject before motion gets back to the starting position at it, blood taking needle innermost cut in skin is a built in problem of this design, when needle point rests on the deepest point that thrusts, maximum dynamics has acted on skin, drive in mechanism and simply bounce the release unit terminal just as a bound disengaging ground, drive in unexpected one of motion end at it and stop, blood taking needle sends a shock wave to skin, activate near the pain receptor of blood taking needle, this will greatly enlarge spontaneous pain.
There is cam-actuated device to avoid in a way the hard stop of blood taking needle, cam mechanism is Spring driving normally, and on the whole better guiding driving, control the track of blood taking needle handle path and then control blood taking needle by the pintle on the cam, cam drive mechanism allows predetermined speed, softer revolution.This will greatly be avoided spontaneous pain, and still, cam-actuated blood-taking device complex structure is manufactured very trouble, and cost is very high, is unfavorable for promoting the use of.
Summary of the invention
The technical problem to be solved in the present invention provides a kind ofly can effectively slow down the blood-taking device of patient's pain.
The technical solution used in the present invention is: a kind of blood-taking device of needle outlet band buffer unit, comprise the flip flop equipment between housing, emission element, housing and the emission element, housing is provided with needle outlet, be provided with elastomeric element in the described housing, elastomeric element provides ejection power, elastomeric element its two ends of when compression prop up respectively housing and emission element, the emission element head can install blood taking needle or with the blood taking needle one, the needle outlet inboard is provided with buffer unit.

As preferably, described buffer unit is antivibrator.
As preferably, the material of described antivibrator adopts TPA, or TPE, or neoprene, or hytrel.
As preferably, described antivibrator is annular or square.
The blood-taking device that rectilinear motion drives is when blood sampling, because the anxious bump that stops causing of Spring driving, the speed of blood taking needle is from extremely zero at a high speed, this swift and violent speed plunges and need to control slowly, the present invention reduces anxious impact effect of stopping with damping material, the present invention by damping material correctly should be used for make blood-taking device be transmitted into slowing down in a flash before the set depth, reduce and absorb since the anxious stopping time of spring gun be positioned at the human body skin layer the blood taking needle head around the diffusion vibrations, reach the effect of approximate cam mechanism ability, thereby reduce impromptu pain.
Beneficial effect of the present invention:
1, reduces the vibrations of diffusion all around that the anxious stopping time is positioned at the blood taking needle head of human body skin layer by damping material, reduce pain.
2, the present invention is simple in structure, is convenient to promote.
