Description of drawings
The above and other feature of the present utility model, character and advantage will become more obvious by the description below in conjunction with drawings and Examples, wherein:
Fig. 1 is the decomposition view of the filter paper volumetric hemostix of an embodiment of the utility model.
Fig. 2 is the assembled view of the filter paper volumetric hemostix of an embodiment of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can be in the situation that do similar popularization, deduction without prejudice to the utility model intension according to practical situations, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.It is not to be to draw according to the condition of equal proportion for embodiment illustrated in figures 1 and 2, and should not be construed as limiting as the protection domain to the utility model actual requirement with this.
As depicted in figs. 1 and 2, in an embodiment of the present utility model, the filter paper volumetric hemostix comprises base 1, filter paper 2, body 3, draw-in groove spare 4, glass capillary 5, plug 6 and cap 7.Filter paper 2 is porosint, is used for absorption blood.Filter paper 2 is contained in the counterbore on the base 1, by base 1 location.Base 1 removably is connected to the left end of body 3.Draw-in groove spare 4 provides slotted eye, and glass capillary 5 is inserted in the slotted eye, is fixed by slotted eye, and draw-in groove spare 4 can be cylindric or other shape, and the two ends diameter of axle of draw-in groove spare 4 is less than the diameter of axle of center section, thereby forms two shaft shoulders, as shown in the figure, the left and right shaft shoulder is arranged.Draw-in groove spare 4 is inserted in the pore of body 3, is formed with the shaft shoulder in the pore of body 3, cooperates with the left shaft shoulder on the draw-in groove spare 4, to play the effect spacing to draw-in groove spare 4.The right-hand member of plug 6 and body 3 removably connects, for example for being threaded, plug 6 has axis hole, and another part of draw-in groove spare 4 is inserted in the axis hole of plug 6, the axis hole aperture of plug 6 is less than the center section of draw-in groove spare 4 or the diameter of axle of arbitrary part, so draw-in groove spare 4 can be spacing by plug 6.Draw-in groove spare 4 limits an activity space between the pore of the axis hole of plug 6 and body 3, so that can axially move freely in this activity space.To such an extent as to having enough length, glass capillary 5 can from the axis hole of plug 6, stretch out the blood collection source that touches, perhaps/and from the pore of body 3, stretch out and touch filter paper 2.Cap 7 removably is connected to the right side of plug 6, the end that may stretch out to seal glass capillary 5.
When gathering blood, open cap 7, the filter paper volumetric hemostix is kept flat, open base 1, so that filter paper 2 separates with glass capillary 5,, glass capillary 5 stretches out plug 6, and glass capillary 5 separates with filter paper 2.At this moment, utilize capillary force to gather blood, when the blood that gathers is full of whole glass capillary 5, obtain quantitative blood.And then cover base 1, and so that glass capillary 5 contacts with filter paper 2, because glass capillary 5 has activity space in body 3, so glass capillary 5 only contacts with filter paper 2, the two can not oppressed relatively.Because blood is infiltration liquid for glass capillary 5, therefore the blood end that can give prominence to glass capillary 5, filter paper 2 can touch blood, by means of the blood in the capillary force absorption glass capillary 5, filter paper 2 is designed to have enough adsorbances, with will be so that the blood in the glass capillary 5 is all adsorbed.
In the aforementioned embodiment, the supporting component of filter paper volumetric hemostix comprises base 1, body 3, plug 6 etc., and glass capillary 5 is arranged in the supporting component movably by means of draw-in groove spare 4.In other embodiment of utility model, base 1 can also be shaft hole matching except with body 3 is threaded, and connects by hinge (for example a slice film body), dismantle the latter two and do not separate, glass capillary 5 can be directly with supporting component in pore cooperate movably
In the aforementioned embodiment, filter paper 2 and glass capillary 5 are arranged in the same supporting component, but its two can be to separate to arrange.
In the aforementioned embodiment, glass capillary 5 can also be the kapillary of being made by other materials.
Although the utility model with preferred embodiment openly as above, it is not to limit the utility model, and any those skilled in the art can make possible change and modification within not breaking away from spirit and scope of the present utility model.Therefore, every content that does not break away from technical solutions of the utility model, all falls within the protection domain that the utility model claim defines any modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
