Description
Technical field
This utility model relates to a kind of blood collection unit for gathering blood.
Background technology
On clinical medicine, or animal and veterinary field, in order to carry out pathological analysis to patient or ill domestic animal, sometimes need to carry out live body blood drawing test, the blood taken out needs to store with a container.The existing container for storing blood is generally test tube, and the structure of this test tube comprises body, and body has opening and blind end, and the opening of body is provided with the pipe close for closed tube.This pipe close is generally just socketed in the open end of body simply, because this test-tube type's blood collection unit generally adopts vacuum blood collection, when body pair pressure is larger, this pipe close is not drawn out easily sometimes, even need to realize opening by means of mechanical system, in the process opened, easily make blood spill on the body of operator, the blood carried the germs of a disease likely causes infection to operator.If coordinate not tight between pipe close with body, then easily make pipe close throw off body, and can gather blood be polluted, or blood is spilt.In addition, existing is what to have been come by different utensils to blood collection and storage, and blood sampling utilizes catcher, and storage blood utilizes test tube to realize.Add blood cost that pathological analysis spends on the one hand, also bring managerial trouble on the other hand.
Chinese utility model patent (the patent No.: 201420438492.8) disclose a kind of vaccum blood collecting test tube, it comprises: test tube body, the first cavity that this test tube body comprises ground floor body, second layer body and is arranged between ground floor body and second layer body, the end of ground floor body is fixedly connected with the end seal of second layer body; Sealing-plug, sealing is arranged at test tube body top, the second cavity of vacuum is formed with test tube body, sealing-plug is provided with one end and extends to the blind hole extending to close sealing-plug upper surface near the capillary tube and one end that try its bottom, capillary tube and blind hole diameter equal and opposite in direction, and coaxially arrange, the other end of capillary tube and the other end of blind hole are at a distance of preset distance; Wherein, sealing-plug also arranges a valve, entered in test tube body to control air by the unlatching of by-pass valve control or close, thus the air pressure in change the second cavity.This utility model can control the air pressure of vaccum blood collecting test tube, and accurately controls the blood flow volume of vaccum blood collecting test tube.
Pipe close on this vaccum blood collecting test tube is also adopt simply to be socketed in, and it also easily runs into above-mentioned problem in application process, and needs blood collector to realize the collection of blood.
Utility model content
For overcoming above-mentioned defect, this utility model technical issues that need to address: a kind of blood collection unit is provided, this blood collection unit in use can well reservoir gather blood, easy to use.
For solveing the technical problem, the technical solution of the utility model: a kind of blood collection unit, comprises body, one end of body is provided with pipe close, and pipe close comprises cap and stopper, cap inwall is formed interior to bulge loop, interiorly in bulge loop, be formed with port, stopper clogs port; Plunger is provided with in body, plunger and inboard wall of tube body face liquid sealing, push rod extend in body from the other end of body and is connected with plunger, it is characterized in that, cap is formed with skirt section, skirt section inner peripheral surface forms female thread, the outer peripheral face of body is formed with the external screw thread matched with female thread; At the interior slotting circle being formed with ring-type to the passage port on bulge loop, slotting circle is positioned at skirt section, for being plugged in body.This blood collection unit, when carrying out blood collection, needs to be combined together use with mozzle, utilizes push rod drive plunger to move in body and in body, form secondary pressure, realizes blood and enter in body.After blood sampling, plunger is parked in the axial positions of body, and makes this blood collection device do blood storage container use.Body makes pipe close be fastened on the open end of body by the cooperation between internal and external screw thread, needs to get blood examination when testing, pipe close of outwarding winding.
As preferably, enclose the position be connected and be provided with the annular convex extend in port to bulge loop with inserting interior, the outer peripheral face of stopper forms cannelure, and annular convex is plugged in cannelure.Be inserted in cannelure by arranging annular convex, and stopper is stably filled in port, stopper provides good sealing for port.
As preferably, be formed with the fillet surface of annular at the upper oral part of annular convex.Fillet surface is set, is convenient to stopper and is tucked in slotting circle.
As preferably, stopper is formed with convex shoulder, the end face of convex shoulder communicates with cannelure, and end face and the interior upper surface to bulge loop of convex shoulder fit.Matched to bulge loop with interior by convex shoulder, and make stopper in cap, have good axis to fill in stability.
As preferably, the one-body molded little convex body having annular on the inner peripheral surface of cap, stopper outer peripheral face is provided with the groove of annular, and little convex body is plugged in groove.Which increase the binding face of stopper and cap, and groove also has certain axial location by little convex body to stopper, make the axial stability of stopper in cap good further.
As preferably, in push rod, side is provided with cutting, for push rod being fractureed from cutting place.For ease of push rod is fractureed, when taking a blood sample complete, plunger being parked in the other end place of body, then radially pulling push rod, and the push rod part reached outside body is fractureed thrown away, placing as being convenient to during blood storage container.
As preferably, the internal face of another side of body is formed with the concaveconvex structure for stopping plunger, the distance between concaveconvex structure with the body other end and the distance between cutting to plunger corresponding.Concaveconvex structure is used for carrying out axial location to plunger, and described distance is corresponding, and after referring to that concaveconvex structure stops plunger, cutting rests on the oral area of the body other end, and is convenient to part unnecessary on push rod to fracture, and improves operational convenience.
Therefore, the beneficial effects of the utility model: this blood collection unit both can be used as the collection of blood, and as blood storage container, can decrease the apparatus amount required for blood collection again, blood collection is convenient, can save the cost of blood collection.On bulge loop, be provided with the slotting circle for being plugged in body open ends in cap, slotting circle can provide good guide effect, is convenient to cap to be screwed on body, the connection good stability of cap on body.By arranging the internal and external screw thread cooperatively interacted between cap upper skirt and body, convenient realization is screwed into cap on body, and the stability of cap on body can ensure, and when getting blood, is also convenient to cap to outward winding, easy to use, safe to use.
