Abstract
The utility model relates to a blood taking tube and comprises substantially a test tube, a tube plug and a safety cap. The tube plug is composed of a core plug and an enclosed jacket. The end-face of the integrated cap plug is smooth. The safety cap is provided with a cavity conforming to the shape of the tube plug. The front portion of the cavity is equipped with a projected port with a through-hole and is equipped with a connecting device of the seat of blood taking needle. The utility model has the advantages of reasonable structure, reliable seal, simple operation, convenient usage and reliable connection of the blood taking needle and the blood taking tube. Further, occurrences of needle skipping in blood taking course can be efficiently avoided, and thereby the fail-safe reliability is good.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of blood taking tube.
Background technology
We know, blood collection, utilization are important curative activities, blood taking needle, the blood taking tube important apparatus that is absolutely necessary.Past generally uses is traditional syringe blood drawing, transfers to blood taking tube again and operation such as inspects by ready samples; In recent years, the vacuum tube single step is directly taken a blood sample becomes advanced blood sampling means.The vacuum tube single step is directly taken a blood sample and is adopted the hemostix of double end blood taking needle, needle holder, vacuum test tube three external members.Existing vacuum test tube mainly is made up of test tube, pipe close, safe head cap, test tube is pumped into vacuum, be added with relevant blood additive in it, outside label, pipe close is used for plug for seal test tube mouth, and its front end face is provided with a groove, and safe head cap tight fit is fastened on test tube and pipe close front end, there is a through hole centre, and an end of double end blood taking needle enters the test tube from this hole penetration tube.Because the blood resistance unit elasticity on the blood taking needle is bigger, blood collection procedure, medical personnel have carelessness slightly, and blood taking needle will be jumped out, and has a strong impact on blood sampling work, also brings unnecessary misery to the patient.Medical personnel must pin blood taking needle with hands, to prevent the generation of bouncing pilotage phenomenon, troublesome poeration, complexity.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and simple to operate, easy to use, blood taking needle is connected with blood taking tube reliably, effectively avoids the bouncing pilotage phenomenon that the blood taking tube that safety is good takes place.
The technical scheme in the invention for solving the above technical problem is: a kind of blood taking tube, mainly form by test tube, pipe close, safe head cap, it is characterized in that: safe head cap is fastened on the pipe close outside, and its front portion is provided with the outstanding port of band through hole, and is provided with blood taking needle needle stand fixture.
This utility model pipe close is made up of core plug and hermetically sealed case, is the cap stopper structure of one, and its end face is smooth.Blood taking needle needle stand fixture can be connected and fixed device for female thread, also can be that coupling type is connected and fixed device.
This utility model is because safe head cap is provided with outstanding port, intermediate throughholes extend longitudinally just, and be provided with blood taking needle needle stand fixture, against existing technologies, this utility model structure is rationally, sealing is reliable, simple to operate, easy to use, blood taking needle is connected with blood taking tube reliably, can effectively avoid the generation of the bouncing pilotage phenomenon of blood collection procedure, safety is good.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is this utility model structural representation;
Fig. 2 is the another kind of structural representation of this utility model safety head cap.
1. test tubes among the figure, 2. pipe close, 3. safe head cap, 4. core plug, 5. hermetically sealed case, 6. cavity, 7. outstanding port, 8. screw thread, 9. hook.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of blood taking tube, mainly form by test tube 1, pipe close 2, safe head cap 3, test tube 1 is pumped into vacuum, is added with the blood additive in it, outside label, pipe close 2 is used for sealing obstruction test tube mouth, safe head cap 3 tight fits are fastened on test tube and pipe close front end, and there is a through hole centre, and an end of double end blood taking needle enters the test tube from this hole penetration tube.
Characteristics of the present utility model are: safe head cap 3 is fastened on test tube 1 and pipe close 2 front ends, and be provided with a cavity 6 consistent with the pipe close external shape, cavity 6 front portions are provided with the outstanding port 7 of band through hole, and are provided with the blood taking needle needle stand are connected and fixed device on outstanding port 7.
This utility model pipe close 2 is made up of core plug 4 and hermetically sealed case 5, process by elastomeric material, the cap stopper structure that is one, its end face is smooth, be provided with the annulus between core plug 4 and the hermetically sealed case 5, be fastened on the test tube 1 port wall, 4 swellings of core plug are in test tube 1 port, hermetically sealed case 5 enclose tightly is outside test tube 1 port, and outer tight double containment effect expands in forming.End face is smooth, processes more convenient, reliable.
This utility model structure blood taking needle needle stand fixture can be to be provided with female thread 8 on the through hole of outstanding port, is threaded with threaded blood taking needle needle stand.Also can be the hook 9 that outstanding port is provided with the band holddown groove, as shown in Figure 2, the blood taking needle needle stand with the band connection bump during use be connected.Like this, blood taking needle is connected with blood taking tube reliably, can effectively avoid the generation of the bouncing pilotage phenomenon of blood collection procedure.
This utility model structure rationally seals reliably, and simple to operate, easy to use, safety is good.
