Abstract
The invention discloses a duck-billed one-way counterseal supervision blood collector. The blood collector mainly comprises four main parts including a vein needle tube 9, a one-way valve assembly, a supervision device assembly and a test tube needle tube 3, wherein the supervision device is composed of a supervision blood collector body, a supervision blood collector upper cover and a supervision film; the one-way valve is composed of a test tube needle stand, a duck-billed one-way counterseal valve core and the supervision blood collector body, wherein the test tube needle stand and the supervision blood collector body are correspondingly sealed and clamped with an edge of the duck-billed one-way counterseal valve core to form a one-way counterseal valve chamber; the duck-billed one-way counterseal valve core is located in the one-way valve chamber; two holes are formed on the side surface of the inner cavity of the supervision blood collector body and externally communicated to the vein needle tube and the one-way valve chamber respectively; and the two holes are communicated through a through groove. Experiments show that pressure in a blood collecting needle at different blood collecting stages can correspond to a specific blood diffusion or contraction vision form, so that a clear state prompt for each of the blood collecting stages as well as simple prompts and reason judgments for possible problems can be given to operators; and more importantly, security of a blood-collected object is guaranteed and secondary medical disaster is reduced.
Description
Technical field
The present invention relates to a kind of duck-beak type counterseal looks and leads hemostix, particularly relate to the reverse-blocking device that prevents blood refluence intravasation from test tube in a kind of venous blood collection process, particularly also design simultaneously has state shows and the guiding operation personnel judge device and reverse-blocking device in the blood collection procedure to be used.
Technical background
At present, the pin that is used for negative pressure test tube venous blood collection is the connectivity needle track, and the possibility of blood two-way flow might take place during blood sampling, enters human vas if backflow behind the invisible spectro harmful reagent mixing blood, will cause serious consequence.In addition, general blood taking needle is the blind type blood taking needle of wearing without any suggesting effect, do not possess any state indicative effect is arranged blood collection procedure, fully whether each stages operating of judging blood sampling with people's operating experience and proficiency level is correct and finish, therefore very high to operator's requirement, be not suitable for vast scope and younger personnel grasp easily fast; Therefore above-mentioned blood sampling mode is that danger is also inaccurate.
Summary of the invention
In order to solve above-mentioned existing in prior technology defective; the invention provides a kind of duck-beak type counterseal looks and leads hemostix; promptly solve the danger of the blood reflux intravasation in the blood collection procedure; design has the prompt facility of overall process state again; further improve the higher needs in the blood collection procedure to safe ready; wherein of paramount importance is to the protective effect of the safety of being got the blood personnel, finishes the directive function to process and then, is implemented in and realizes 2 functions on the hemostix simultaneously.
A kind of duck-beak type counterseal proposed by the invention is looked and is led hemostix, comprises intravenous needle needle tubing 9, check valve combination, looks four major parts such as leading device combination and test tube pin needle tubing 3.Wherein look and lead device and lead the hemostix body by looking, look to lead the hemostix loam cake and look and lead film and constitute; Check valve is by test tube pin needle stand, duck-beak type one-way reverse-blocking spool and look and lead the hemostix body and constitute.Described test tube pin needle stand and looking is led the edge of the corresponding sealing of hemostix body clamping duck-beak type one-way reverse-blocking spool and is formed an one-way reverse-blocking valve pocket, and duck-beak type one-way reverse-blocking spool is positioned at this check valve intracavity.Look and lead hemostix chamber body side 2 holes are arranged, outwards lead to intravenous needle needle tubing and check valve cavity respectively, have groove to be communicated with between 2 holes.
A kind of duck-beak type counterseal proposed by the invention is looked and is led hemostix, comprises following main contents:
Between intravenous needle needle tubing and test tube pin needle tubing, be provided with to look and lead device and/or duckbill check valve, be used for finishing simultaneously counterseal and look and lead two functions, test tube pin needle tubing is pointed at the tip that wherein is placed in the duck-beak type counterseal spool of check valve intracavity, and check valve is near test tube pin needle tubing; Look and lead device near the intravenous needle needle tubing, the sequencing of blood flow warp is during blood sampling: the intravenous needle needle tubing, look and lead device, check valve and test tube pin needle tubing, duck-beak type counterseal spool is by the elastomeric material manufacturing, the duckbilled point of duck-beak type counterseal spool has opening, the opening of the duck bill of duck-beak type counterseal spool is in closed condition during normality, the opening that runs into duck bill when deriving from venous forward blood pressure is opened, blood passes the intravenous needle needle tubing and looks the opening that enters the inside of duck-beak type counterseal spool behind the groove of leading device and open duckbilled from vein and enters test tube pin needle tubing, enter at last in vitro, if because abnormal cause causes venous pressure to reduce, when in vitro pressure was higher than intravascular pressure, the buffer brake of test tube inside was closed the opening of the duck bill of duck-beak type counterseal spool.When other user demand, can and look at the intravenous needle needle tubing to lead between the device or between check valve and test tube pin needle tubing and install hose connector additional, protection vein needle point does not damage the blood vessel of human body when being convenient to operate.Look and lead looking in the device to lead film be the elastomeric material manufacturing, looking when leading the general state of film when not using is to paste to cover looking on the groove of leading the hemostix chamber body, can fill expansion when running into blood pressure.Look the direction of leading film contact blood face and be the guide face of looking that observation post uses, the inclined-plane at intravenous needle tip points to the direction of observation of looking the guide face place.
Good effect of the present invention is: at first ensure healthy and safe by the blood sampling personnel, look simultaneously and lead operator and objectively easily operate by looking figure or the color colourity that guide face presents, finally realize safe and efficient correct negative pressure blood sampling operation.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is that duck-beak type counterseal proposed by the invention is looked and led hemostix;
Fig. 2 is that the duck-beak type counterseal that has hose connector proposed by the invention is looked and led hemostix;
