Abstract

The utility model discloses a non-vacuum blood collecting pipe, which is composed of a pipe body and a cover body used to open and close the pipe body mouth, wherein the inside of the cover body is provided with a plurality of protruding parts; the external edge of the pipe body is provided with a protruding ring; the pipe body is elastically chucked and sealed with protruding part of the cover body through the protruding ring; the external edge of the pipe body along the circular direction is provided with a chucking groove; the inner side of the cover body is provided with a step; a chucked trough and a step correspondingly match with each other; the chucked trough on the external edge of the pipe body is provided with a plurality of serrated protruding blocks; meanwhile, the step on the inside of the cover body is provided with a plurality of corresponding serrated protruding blocks; and each protruding block is provided with two guiding sides. Through improvement of the structures of the pipe body and the cover body, the utility model makes the specimen easy to collect and to safely seal up in the pipe body and prevents the specimen in the pipe from splashing out when the cover body is opened.

Description

A kind of antivacuum blood taking tube

Technical field

This utility model relates to a kind of blood taking tube, refers in particular to a kind of antivacuum blood taking tube of specializing in blood capillary blood sampling usefulness.

Background technology

Recently, quite flourishing along with the continuous development of medical science and technology by the technology of hemodiagnosis various diseases, therefore, in the diagnosis various diseases, need blood count usually.At present, though have multiple blood-taking device, mainly be to adopt to form vacuum test tube recently by disposable syringe, holder and particular needle, i.e. the mode of taking a blood sample by pressure differential.The vacuum blood collection tubular construction is most, and vacuum test tube is made under vacuum state, is vacuum in the storage vascular bodies in order to have a storage vascular bodies and to prevent the lid composition that blood outflows, and lid seals up the body mouth, lasting maintenance vacuum state in the body.When utilizing this vacuum test tube to take a blood sample, one end of said syringe syringe needle is inserted in the human vein, syringe other end syringe needle is connected in the vacuum test tube, at this moment, form pressure differential between human vein and the vacuum test tube, blood flows in the body by syringe, finishes blood sampling.The vacuum test tube of this spline structure, generally carry out elasticity between body and the lid and insert sealing by projection, in the time will opening blood taking tube, people generally need bigger power lid could be separated with body, in the time of so just may causing pulling out lid blood be taken out of because of overexerting, might pollute staff's hands or be infected with on the space outerpace, thereby cause the cross infection in the work.In the blood sampling of infant routine blood test project,, be difficult to gather venous blood and do blood cell inspection, and, make the assay distortion because of the negative pressure of vacuum tube easily causes breaking of infant hemocyte because of the particularity of its blood vessel and hemocyte.And in blood capillary blood sampling field, do not have special blood taking tube again.At present comparatively many is adds edta salt with the centrifuge tube of 0.5～1.5ml and adopts capillary blood, because of the centrifuge tube inwall does not have silicidation, under the few prerequisite of blood capillary blood volume, be difficult to collect required blood volume, strengthen patient's misery, and centrifuge tube does not have safety head, easily causes biological pollution when uncapping.

The utility model content

Defective at the technique scheme existence, the purpose of this utility model is to provide a kind of antivacuum blood taking tube, by architecture advances to lid and body, can make specimen be easy to gather and can be enclosed in the body safely, and when preventing opening cover in the pipe specimen spatter outward.

For achieving the above object, be achieved by the following technical solution:

A kind of antivacuum blood taking tube, form by body with in order to the lid that opens and closes the body mouth, the inboard of lid is provided with a plurality of projections, the body outer rim is provided with bulge loop, body carries out elasticity by bulge loop with the projection of lid and engages sealing, described body outer rim along the circumferential direction is provided with a slot, the inboard of lid has a step, slot and step corresponding matching, it is characterized in that: be provided with a plurality of dentation projections in the slot of body outer rim, the step of lid inboard is provided with corresponding a plurality of dentation projection simultaneously, has two spigot surfaces on each projection.

One side of described body port has a breach, at the opposite side formation blood sampling flange of port.

Adopt the blood taking tube of said structure, by on body outer rim slot and lid inboard, all being provided with the dentation projection of corresponding matching, when closing lid and body, body carries out elasticity engaging sealing by the projection of bulge loop and lid inboard, the interlaced snap-lock of dentation projection of while lid and body correspondence, because the spigot surface that has separately between the dentation projection of staggered interlock, during engaging between the dentation projection locking after such overstocked effect can form a kind of special echo that can allow people's perception, can determine to manage the locking fully of intravital specimen.In the time will opening lid, as long as with the rotation of staggering mutually of lid and body, this moment is because the spigot surface that has on the dentation projection, can easily unclamp interlock between the dentation projection and body and engage sealing with elasticity between the lid, user does not need the too much power of expense that lid is opened, and prevents to spatter outside the specimen in the body when opening lid.On the other hand, have breach on body port one side, opposite side forms the blood sampling flange, is easy to collect specimen, and inboard wall of tube body makes blood wall cling phenomenon not occur through silicidation, finishes check under the blood sampling volume of minimum, adds corresponding anticoagulant or coagulant in the pipe.

The specific embodiment

As Fig. 1,2, shown in 3, a kind of antivacuum blood taking tube, form by body 1 with in order to the lid 2 that opens and closes the body mouth, the inboard of lid 2 is provided with a plurality of projections 3, body 1 outer rim is provided with bulge loop 4, body 1 carries out elasticity by bulge loop 4 with the projection 3 of lid 2 and engages sealing, body 1 outer rim along the circumferential direction is provided with a slot 5, the inboard of lid 2 has a step 6, slot 5 and step 6 corresponding matching, be provided with a plurality of dentation projections 7 in slot 5, the step 6 of lid 2 inboards is provided with corresponding a plurality of dentation projection 7 simultaneously, has two spigot surfaces 71 on each

dentation projection

7,72; On the other hand, have breach on body 1 port one side, opposite side forms blood sampling flange 8, is easy to collect specimen.

User is when closing lid 2 and body 1, body 1 carries out elasticity engaging sealing by the projection 3 of bulge loop 4 and lid 1 inboard, the dentation projection 7 interlaced snap-lock of while lid 2 and body 1 correspondence, because the spigot surface that has separately between the dentation projection 7 of staggered interlock, during engaging between the dentation projection 7 locking after such overstocked effect can form a kind of special echo that can allow people's perception, can determine the specimen locking fully in the body 1.In the time will opening lid 2, as long as with the rotation of staggering mutually of lid 2 and body 1, this moment is because the

spigot surface

71,72 that has on the dentation projection 7, can easily unclamp the interlock of 7 of dentation projections and body 1 and engage sealing with elasticity between the lid 2, user does not need the too much power of expense that lid 2 is opened, and prevents to spatter outside the specimen in the body 1 when opening lid 2.
