Abstract
The utility model discloses a positioning shield, which is a positioning device for a laser blood collecting device. The positioning shield is movably arranged below a focusing lens of the laser blood collecting device and in form of a column body with through-hole. The height of the column body is equivalent to the focus of the focusing lens. The utility model not only provides the positioning purpose, but also avoids the cross infection for the convenient replacement.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, refers to that especially a kind of laser hemostix is with locating protective cover.
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.
So just the someone expects taking a blood sample with laser, concrete mode is: after the collimated laser beam that generating laser is sent is assembled with aggregation lens, form a laser point, finger is placed on this laser point again, it is broken will to point " thorn " rapidly, to reach the purpose of blood sampling.This mode can be taken a blood sample fast and accurately, and deep mixed problem when not adopting blood taking needle, for the child, because do not look at blood taking needle straight, does not therefore also just have fear and pain.
Yet,, therefore need the position of a positioner usually, and when hemorrhage finger touches positioner, very easily cause cross infection with fixed finger because the accumulation point of above-mentioned laser hemostix is a predetermined fixed; In addition, can pollute amasthenic lens after the steam evaporation on blood and the finger, this not only can influence gathering, more can cause cross infection indirectly.
The utility model content
The purpose of this utility model is to provide a kind of location protective cover that prevents cross infection and can prevent to pollute camera lens.
For achieving the above object, technical solution of the present utility model is: a kind of location protective cover, and its active below that is arranged at laser hemostix amasthenic lens is for having the cylinder of through hole; The height of this cylinder equals the focal length of amasthenic lens.
Be provided with protecting film in this through hole.
This cylinder outside is provided with flange, and the laser hemostix of amasthenic lens below is provided with slot that should flange.
This flange is outward extended with the boss of L type.
On this slot lens assembly, and amasthenic lens is located in the lens assembly.
After adopting such scheme; because this utility model is to be movably set in the amasthenic lens below; and the height of its cylinder equals the focal length of condenser lens just; therefore when reaching positioning function; also can conveniently change, thereby avoid cross infection, and protecting film there is protective effect to amasthenic lens; can prevent the steam evaporation on blood and the finger and pollute amasthenic lens, more can further prevent cross infection.

The specific embodiment
As shown in Figures 1 and 2, location of the present utility model protective cover 1 is the positioner of laser hemostix, it is the cylinder 12 with through hole 11, be provided with protecting film 2 in the through hole 11 of cylinder 12 tops, cylinder 12 outsides are provided with locating flange 13, this flange 13 also is outward extended with the boss 14 of L type, and this boss 14 can conveniently take out location protective cover 1; And the height of this cylinder 12 equals the focal length (comprising aggregation lens and protecting film) of hemostix just.
This location protective cover 1 is movably set on the laser hemostix, be positioned at amasthenic lens 3 belows, example of the present utility model is that amasthenic lens 3 is located in the lens assembly 4 (please cooperate shown in Figure 3), lens assembly 4 is fixed on generating laser (will not the illustrate) below of hemostix, lens assembly 4 relative aggregation lens 3 belows are provided with location slot 41, to cooperate the locating flange 13 of location protective cover 1.
During use, shown in Fig. 4,5, be inserted in location protective cover 1 in the slot 41 of lens assembly 4 with its flange 13, finger is close proximity to cylinder 12 belows of location protective cover 1, laser beam penetrates protecting film 2 through behind the amasthenic lens 3 again, because the height of location protective cover 1 cylinder 12 equals the whole focal length of hemostix just, therefore laser beam just focuses on the skin of finger, and " thorn " broken finger, thereby finish the blood sampling operation.Afterwards, thereby, change another new location protective cover, use in order to next blood sampling person with taking out in exhausted location protective cover 1 slot 41.This mode can be avoided cross infection, and 2 pairs of amasthenic lens 3 of protecting film have protective effect, can prevent the steam evaporation on blood and the finger and pollute amasthenic lens 3, more can further prevent cross infection.
Claims (5)
1, a kind of location protective cover is characterized in that: its active below that is arranged at laser hemostix amasthenic lens, for having the cylinder of through hole; The height of this cylinder equals the focal length of amasthenic lens.
2, location as claimed in claim 1 protective cover is characterized in that: be provided with protecting film in this through hole.
