Abstract
The utility model discloses an anodynia blood collecting device, mainly including a laser emitter, a focusing lens and a positioning device arranged on a coaxial line. The utility model adopts the focused parallel laser beams to form a laser point to collect blood, so the blood collecting process is fast and accurate. The utility model overcomes the defect of depth differences when using the blood collecting needles in the blood collection technology known in the prior art. For child, the child has no fear or ache during the blood collecting operation because the child does not directly see the blood collecting needle.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, refers to a kind of painless blood-taking device especially.
Background technology
It is one of requisite program in the Clinical Laboratory that collection blood provides sample for test.The mode of adopting tip blood commonly used is to thrust finger skin rapidly with blood taking needle, makes it hemorrhage, and then blood is extruded in order to check.Yet, though this mode is simple, complete experience during operation, and the degree of depth of uncontrollable acupuncture with the medical worker.Cross when dark when the blood sampling point wound of finger, often cause and bleed too much, even infect, cause wound to be difficult for healing, thereby bring misery to patient.In addition, for the juvenile, because the juvenile has fear to acupuncture, and be unwilling to take a blood sample, thereby bring unnecessary trouble for blood sampling work.Therefore above-mentioned blood sampling mode can not adapt to the demand of modern medical service.
The utility model content
The purpose of this utility model is to provide a kind of painless blood-taking device, and what this device can be quick, accurate and painless takes a blood sample.
For achieving the above object, technical solution of the present utility model is: a kind of painless blood-taking device mainly comprises the generating laser, amasthenic lens and the positioner that are positioned on the coaxial line.
This generating laser is the erbium rod.
This positioner is dismountable location protective cover.
This amasthenic lens has protecting film.
After adopting such scheme,, therefore fast, accurately, there is not in the located by prior art deep mixed problem when adopting blood taking needle because this utility model utilizes parallel laser beam to focus on laser point adversary's fingering row blood sampling that the back forms; And,, therefore just do not have fear and pain because do not look at blood taking needle straight for the child yet.

Fig. 2 is the stereo appearance figure of this utility model location protective cover;
Fig. 3 is the schematic perspective view (oppositely) of this utility model lens assembly;
Fig. 4 is the combination action sketch map of this utility model location protective cover and lens assembly;
Fig. 5 is the assembled state sketch map of this utility model location protective cover and lens assembly.
The specific embodiment
As shown in Figure 1, this utility model mainly comprises generating laser 1, amasthenic lens 2 and positioner 3, and generating laser 1, amasthenic lens 2 and positioner 3 are positioned on the same axis.This generating laser 1 can be the erbium rod, and amasthenic lens 2 then is common convex lens.Not contaminated for len, this utility model can add a protecting film 4 below aggregation lens, and protecting film 4 also has the accumulative effect of secondary.
The operation principle of this utility model blood-taking device is: the collimated light beam line focus camera lens 2 that generating laser 1 is sent focuses on the back and forms a laser point, at this moment, if finger is placed on this laser point, can be rapidly that finger " thorn " is broken, to reach the purpose of blood sampling; Positioner 3 then sets in advance the focus point position at aggregation lens 2, and finger can be located fast and accurately by this positioner 3.
Because this utility model utilizes parallel laser beam to focus on laser point adversary's fingering row blood sampling that the back forms, therefore fast, accurately, there is not in the located by prior art deep mixed problem when adopting blood taking needle; And,, therefore just do not have fear and pain because do not look at blood taking needle straight for the child yet.
In addition, prevent that cross infection from being the problem that at first will consider in the medical apparatus and instruments, and in this utility model, when hemorrhage finger touches positioner 3, very easily cause cross infection.For addressing this problem, this utility model adopts disposable location protective cover 5.
Above-mentioned location protective cover 5 as shown in Figure 2, it is the cylinder 52 with through hole 51, is provided with protecting film 4 in the through hole 11 of cylinder 52 tops, and cylinder 52 outsides are provided with locating flange 53, this flange 53 also is outward extended with the boss 54 of L type, and this boss 54 can conveniently take out location protective cover 5; These location protective cover 5 activities are inserted on the lens assembly 6, and the height of its cylinder 52 equals the focal length (comprising aggregation lens and protecting film) of blood-taking device just.
During use, shown in Fig. 4,5, be inserted in location protective cover 5 in the slot 61 of lens assembly 6 with its flange 53, finger is close proximity to cylinder 52 belows of location protective cover 5, laser beam penetrates protecting film 4 through behind the amasthenic lens 2 again, because the height of location protective cover 5 cylinders 52 equals the focal length of amasthenic lens just, therefore laser beam just focuses on the skin of finger, and " thorn " broken finger, thereby finish the blood sampling operation.Afterwards, the location protective cover 5 that more renews uses in order to next blood sampling person, thereby has avoided cross infection.And 4 pairs of amasthenic lens 2 of protecting film have protective effect, can prevent that the steam on blood and the finger from evaporating and pollution amasthenic lens 2, more can further prevent cross infection.
