Abstract
The utility model relates to the field of vacuum blood collection technology, in particular to a switch-mode serum intermediate-layer test tube. The switch-mode serum intermediate-layer test tube is formed by a splash-proof cap, a rubber plug, a switch lever, a conduit plug, a conduit and a conduit sleeve. The switch lever is a T-shaped plastic lever. The upper end of the switch lever is arranged in the rubber plug and is glued with the rubber plug into a whole. The lower end of the switch lever is arranged in the conduit plug made of butyl rubber materials. The conduit is arranged in a tube body and fused with the bottom of the tube body into a whole. A lower end port of the conduit extends out of the bottom of the tube body. The conduit plug is inserted in an upper port of the conduit. The conduit plug is in interference fit with the conduit. The switch-mode serum intermediate-layer test tube can be used for directly sampling from the middle position of pure serum, avoids interference of a fibrous protein impurity layer to the purity of the serum, and improves accuracy of detection results for blood specimens.
Description
Technical field
The utility model relates to the vacuum blood drawing technique field, particularly relates to a kind of serum middle level switching regulator developmental tube.
Background technology
Existing separation gel developmental tube is the upper end and opens wide the straight tube of lower end closed.After centrifugal treating that it is drawn blood, have one deck impurity and float on the serum surface.Because impurity floats on the serum surface; extend into downwards from the mouth of pipe in the process of drawing serum the serum at sampling probe, syringe needle often can be blocked in a single day from the floating layer of impurity process; stop up even cause half of sampling probe, also can cause the blood preparation testing result inaccurate.This part impurity mainly is comprised of the materials such as little molecule micelle in the fiber protein yarn in the blood, grease and the separation gel.Because chemical property and the physical property of described impurity have diversity, with its fast, intactly to remove be very difficult.
The utility model content
The utility model is for solving the deficiencies in the prior art, provide a kind of and need not to remove the impurity on serum surface for the medical personnel, just can avoid sampling probe in extracting the serum process, contact with impurity fully, the serum purity that assurance is extracted, avoid the blocked serum middle level switching regulator developmental tube of syringe needle.
The scheme that solves the utility model technical matters is:
Serum middle level switching regulator developmental tube is made of splash cap, plug, switch lever, catheter stopper, conduit and sheathed catheter.Body is glass tube columnar, lower end closed, is plugged with plug in the upper port of body, and splash cap is enclosed within on the plug.Switch lever is the plastic bar of a T font, and it is interior and bonding as a whole with plug that the upper end of switch lever is in described plug, and the lower end of switch lever is in the catheter stopper of butyl rubber material, and bonding as a whole with catheter stopper.The material of catheter stopper is butyl rubber, and catheter stopper is divided into up and down two parts at body, and top is up big and down small reverse frustoconic, and the bottom is most advanced and sophisticated inverted cone down.Have in the inside of body one with body coaxial inner conductor and the conduit that is integrated with the bottom fusion of body, the upper port of conduit is in the first half of body, the lower port of conduit is stretched out from the bottom of body, and the sheathed catheter of butyl rubber material is placed in the lower port of conduit.Described catheter stopper is inserted in the upper port of described conduit, and catheter stopper becomes the interference fit relation with conduit.Catheter stopper is inserted vertical extension in the upper port of conduit and is filled in vertical extension in the upper port of body greater than plug.
The lab technician will be equipped with the utility model of blood sample through after the separation of hydro-extractor, and the liquid in the body is impurity layer, serum, separation gel, haemocyte from top to bottom successively, and the upper port of conduit is arranged in the impurity layer below and is in serum.At this moment, the lab technician only needs first with under the catheter extraction, again plug is upwards extracted together with splash cap, switch lever is just extracted catheter stopper out from the upper port of conduit, because this moment, the suitable for reading of body opened wide fully, the serum in the body enters the upper port of conduit and directly flows out from the lower port of conduit under Action of Gravity Field, when treating that impurity layer drops near conduit suitable for reading with the liquid level of serum, again catheter stopper is filled in the suitable for reading of conduit, serum stops to flow out at once.
Adopt such scheme, compared with prior art, the utlity model has following marked improvement:
1. owing to the utility model can directly be taken a sample from the middle position of pure serum, avoid traditional sampling probe to stretch into the fibrin impurity layer of serum liquid level the process of serum to the interference of serum purity from the top, improved the accuracy of blood preparation testing result.
2. because the utility model has consisted of the gravity flow switching system of serum sampling by conduit, switch lever and catheter stopper, therefore conventional syringe and sampling needle have been saved to the aspiration procedure of serum, both saved medical equipment, make again the sampling process of serum easier, improved the work efficiency of examination of serum.

Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Serum middle level switching regulator developmental tube is made of splash cap 1, plug 2, switch lever 3, catheter stopper 4, conduit 5 and sheathed catheter 6.Body 7 is glass tubes columnar, lower end closed, is plugged with plug 2 in the upper port of body 7, and splash cap 1 is enclosed within on the plug 2.Switch lever 3 is plastic bars of a T font, and the upper end of switch lever 3 is in the described plug 2 and is bonding as a whole with plug 2, and the lower end of switch lever 3 is in the catheter stopper 4 of butyl rubber material, and bonding as a whole with catheter stopper 4.The material of catheter stopper 4 is butyl rubber, and catheter stopper 4 is divided into up and down two parts at body, and top is up big and down small reverse frustoconic, and the bottom is most advanced and sophisticated inverted cone down.Have in the inside of body 7 one with body 7 coaxial inner conductors and the conduit 5 that is integrated with the bottom fusion of body 7, the upper port of conduit 5 is in the first half of body 7, the lower port of conduit 5 is stretched out from the bottom of body 7, and the sheathed catheter 6 of butyl rubber material is placed in the lower port of conduit 5.Described catheter stopper 4 is inserted in the upper port of described conduit 5,5 one-tenth interference fit relations of catheter stopper 4 and conduit.Catheter stopper 4 is inserted vertical extension in the upper port of conduits 5 and is filled in vertical extension in the upper port of body 7 greater than plug 2.
The lab technician will be equipped with the utility model of blood sample through after the separation of hydro-extractor, and the liquid in the body 7 is impurity layer 11, serum 8, separation gel 9, haemocyte 10 from top to bottom successively, and the upper port of conduit 5 is arranged in impurity layer 11 belows and is in serum 8.At this moment, the lab technician only needs first sheathed catheter 6 to be taken off, again plug 2 is upwards extracted together with splash cap 1, switch lever 3 is just extracted catheter stopper 4 out from the upper port of conduit 5, because this moment, the suitable for reading of body 7 opened wide fully, the serum 8 in the body 7 enter the upper port of conduit 5 and directly flow out from the lower port of conduit 5 under Action of Gravity Field, when treating that impurity layer 11 drops near conduit 5 suitable for reading with the liquid level of serum 8, again catheter stopper 4 is filled in the suitable for reading of conduit 5, serum 8 stops to flow out at once.
