Abstract
The utility model relates to an artifical negative pressure tip blood sampling pipe, it includes the body of being made by the medical grade rubber of flexibility or plastics, the body upper end is sealed, the lower extreme is provided with sharp mouth, is provided with the cavity that holds blood in the body, be provided with on the sharp mouth with the blood sucking mouth of cavity intercommunication. The utility model discloses more change the hard material of present existing tip blood heparin tube into the soft plastics material, the upper end sets up the lid to artifical extrusion heparin tube forms the negative pressure, and the initiative inhales the heparin tube with blood, does not need extrusion finger repeatedly, has reduced by sampling people's misery. Still can avoid blood to expose in the air, form aerosol contaminated air, avoid the pollutant in the air to get into blood simultaneously, influence the testing result. The design of the point end can increase actual available blood volume, reduces the blood sampling volume.
Description
Technical field
This utility model relates to field of medical appliances, particularly relates to a kind of artificial negative pressure peripheral blood sampling tube.
Background technology
The finger peripheral blood gatherer process detected for medical science is at present all extruding finger, allows blood flow into uncovered blood taking tube, or takes a blood sample with capillary pipette.In peripheral blood gatherer process, need constantly to extrude peripheral vessel, allow blood flow out, the blood of q.s could be collected.
Existing peripheral blood blood taking tube is uncovered, and blood can only be allowed automatically to flow into, or the mouth of pipe is near finger scraping blood.In peripheral blood gatherer process, need constantly to extrude peripheral vessel, easily cause mismatching of child and infant; And blood in atmosphere, easily pollutes, affect the accuracy of testing result.Be circular bottom another blood taking tube, peripheral blood sampling quantity is originally little, and the dead of round bottom is comparatively large, causes actual available blood flow volume to reduce.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model there is provided a kind of artificial negative pressure peripheral blood sampling tube, and during blood sampling, this sampling tube can utilize negative pressure initiatively to draw blood, does not need repeatedly to extrude finger, decreases the misery being sampled people.
(2) technical scheme
In order to solve the problems of the technologies described above, this utility model provides a kind of artificial negative pressure peripheral blood sampling tube, it comprises the body be made up of the medical grade rubber of flexibility or plastics, body upper end seals, body bottom is provided with sharp mouth, be provided with the chamber of containment blood in body, sharp mouth be provided with the mouth of sucking blood with described chamber.
Further, whole described sharp mouth is arranged in described body; Namely the lower surface of sharp mouth is arranged on described tubular body, or flushes with the lower surface of described body.
Further, described body upper end is provided with lid, and the upper end open of described chamber is sealed by lid by described body.
Further, described lid is threadedly arranged on described body upper end.
Further, described lid is blocked by the upper end of plug-in mounting mode by described body.
Further, described body is slender tube body.
Manual compression body during blood sampling, goes out blood taking tube and forms negative pressure in pipe, then press close to point blood outlet by the mouth of pipe, utilize negative pressure that blood is initiatively sucked blood taking tube by air extrusion, then the tube wall that comes up, very easy to use.
(3) beneficial effect
Technique scheme of the present utility model has following beneficial effect: the hard material of current existing peripheral blood blood taking tube is replaced with flexible plastic material by this utility model, upper end arranges lid, so that manual compression blood taking tube forms negative pressure, initiatively blood is sucked blood taking tube, do not need repeatedly to extrude finger, decrease the misery being sampled people.Also can avoid blood in atmosphere, form Aerosol Pollution air, avoid the pollutant in air to enter blood simultaneously, affect testing result.The design of the point end can increase actual available blood flow volume, reduces blood sampling volume.

Fig. 1 is the structural representation of this utility model embodiment;
Structural representation when Fig. 2 is the using state of this utility model embodiment;
Wherein, 1: body; 2: lid; 3: chamber; 4: sharp mouth.
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of this utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more; Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " rear end ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on orientation shown in the drawings or position relationship, only this utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " is connected ", " connection " should be interpreted broadly, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in this utility model can be understood.
As shown in Figure 1-2, one described in the present embodiment artificial negative pressure peripheral blood sampling tube, it comprises the body 1 be made up of the medical grade rubber of flexibility or plastics, body 1 upper end seals, body 1 lower end is provided with sharp mouth 4, be provided with the chamber 3 of containment blood in body 1, sharp mouth 4 be provided with the mouth of sucking blood be communicated with chamber 3.Wherein, whole sharp mouth 4 is arranged in body 1; Namely the lower surface of sharp mouth 4 is arranged on body 1 inside, or flushes with the lower surface of body 1.
Inner by sharp mouth 4 being arranged on body 1, be convenient to sampling tube and stand on platform, preferably, sharp mouth 4 lower surface is shunk in body 1 inner, like this when standing on platform, sharp mouth 4 not with contact with platform.
Lid 2 is threadedly arranged on body 1 upper end, and the upper end open of chamber 3 is sealed by lid 2 by body 1.In addition, lid can also adopt the modes such as plug-in mounting mode to be arranged on the upper end of body, and chamber upper end open is blocked.
As shown in Figure 2, manual compression body during blood sampling, air extrusion is gone out blood taking tube, forms negative pressure in body 1, then sharp mouth is pressed close to point blood outlet, utilize negative pressure that blood is initiatively sucked blood taking tube, come up tube wall again, and blood is inhaled in body automatically, very easy to use, decrease the number of times of extruding finger, decrease patient's misery.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by this utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand this utility model thus design the various embodiments with various amendment being suitable for special-purpose.
