Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of hemostix.
Background technology
A lot of disease all needs the inspection carrying out blood when the indefinite cause of disease, mainly pass through venipuncture.General to the inspection item of blood more than one, the general measures one that existing technology adopts is repeatedly puncture blood collecting; Two is after being taken a blood sample by hemostix, is expelled to respectively in different blood taking tubes according to the blood that hemostix extracts by the quantitative requirement of inspection item, then the blood in each blood taking tube is taken different section office respectively carries out laboratory examination.
There is following problem in tradition Blood collection: repeatedly punctures and bring unnecessary misery to patient.When being injected to different blood taking tubes by hemostix inner blood, blood is easily infected, and cause blood Query Result to occur deviation, check result is inaccurate.And if traditional syringe-type hemostix when piston is extracted into the rear end of syringe firmly excessive being easy to piston is pulled out syringe, cause the blood loss in syringe, and puncture needle is easy to damage patient.
Utility model content
For overcoming problems of the prior art, this utility model provides a kind of one-time puncture can gather many bottles of blood to be checked simultaneously, and safer hemostix.
The technical scheme in the invention for solving the technical problem is: this kind of hemostix, and comprise syringe, piston, piston pumping rod and puncture needle, the front end that puncture needle is fixedly connected on syringe communicates with syringe; It is characterized in that: syringe outer circumference surface barrel is provided with some rubber stoppers, between rubber stopper top and syringe inner chamber tube wall, form a groove; Also comprise some blood taking tubes, blood taking tube top is provided with sealing-plug, and sealing-plug is inserted with blood taking needle, and blood taking needle one end penetrates sealing-plug and is communicated with blood taking tube, the other end penetrates rubber stopper and is communicated with syringe, and described blood taking needle penetrates one end of rubber stopper not higher than syringe inner chamber tube wall; The postive stop baffle of control piston moving range is provided with at back end of syringe.
Further, described postive stop baffle has two pieces, and outer circumference surface tube wall one end that postive stop baffle penetrates syringe extends to syringe inner chamber, and the other end is outside syringe, and postive stop baffle and syringe inner chamber tube wall contact position are provided with projection.
Further, the width of described piston is greater than the width of groove.
Further, described rubber is plugged with three, and blood taking tube corresponding with it has three.
Further, described rubber stopper is in line distribution on syringe axis direction.
To sum up, the beneficial effect of technique scheme of the present utility model is as follows: this use is novel is disposable hemostix, the collection of many bottles of blood to be checked can be obtained by a venipuncture simultaneously, avoid the injury of many patients that repeatedly punctures, and this hemostix achieves sealed blood sampling, avoid infection and the cross infection of blood, improve blood sampling efficiency.Limited the moving range of piston by positive stop, ensure that the safety of hemostix.

Detailed description of the invention
Be described in detail to characteristic sum principle of the present utility model below in conjunction with Fig. 1-Fig. 3, illustrated embodiment, only for explaining this utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1, this kind of hemostix comprises syringe 1, piston 2, piston pumping rod 3 and puncture needle 4.Described syringe 1 is cylindrical, and syringe 1 front end is fixed with puncture needle 4, and puncture needle 4 is communicated with syringe 1, and the other end of syringe 1 is uncovered.One end of described piston pumping rod 3 is fixedly connected with piston 2 and is placed in syringe by the opening end of syringe 1, and the diameter of piston 2 is suitable with syringe inner chamber caliber; The other end of piston pumping rod 3 is outside syringe opening end.
The syringe 1 excircle barrel of this hemostix is provided with some rubber stoppers 5, rubber stopper 5 is embedded on syringe tube wall, the thickness of rubber stopper 5 is less than the thickness of syringe 1 tube wall, is therefore all formed with a groove 6 between the top of each rubber stopper 5 and syringe 1 inner chamber tube wall.During use, side syringe 1 being provided with groove 6 is downward, makes the blood of the extraction in syringe 1 can flow to groove 6 smoothly, be entered in blood taking tube 7 by blood taking needle 8.
Also comprise some blood taking tubes 7, be fixed with sealing-plug at the top of blood taking tube 7, described blood taking tube is existing, and its inside is vacuum.In use, sealing-plug blood taking needle 8 being penetrated blood taking tube top is communicated with blood taking tube 7; The other end of blood taking needle 8 then penetrates rubber stopper 5 and syringe 1 inner space, so just achieves being communicated with of blood taking tube 7 and syringe 1.Blood taking needle 8 penetrates one end needle tip of rubber stopper 5 not higher than syringe inner chamber tube wall, and namely the needle tip of blood taking needle is in described groove 6.The caliber of described blood taking needle 8 is comparatively large, and the blood of needle tubing can be entered in blood taking tube 7 smoothly after groove 6, blood taking needle 8.Blood taking tube can be pulled up after all having gathered blood in individual blood taking tube and deliver to each inspection section office and check.
As shown in Figure 2, further, the width L1 of described piston 2 should be greater than the width L2 of groove 6, avoids groove 6 to affect the motion of piston 2, ensures the smoothness of piston 2 movement.
Further, described rubber stopper 5 has three, and blood taking tube 7 corresponding with it also has three.Namely one-time puncture blood drawing can realize three blood taking tubes and collect blood to be checked simultaneously.Avoid multiple inspection to need repeatedly to puncture and bring the misery of patient.This kind of all-sealed blood collection procedure also ensure that the not contaminated and cross infection of blood.In order to the smoothness of blood flow, during design, rubber stopper 5 is pointed to layout along the direction of syringe axis.
Also be provided with the postive stop baffle 9 of control piston moving range in the rear end of syringe 1, ensure that piston 2 can only move and can not be drawn out syringe 1 in syringe 1.Avoid piston 2 careless in pull-out time syringe 1 in the waste of blood extracted, avoid the injury of rocking patient of syringe 1 and puncture needle 4 when piston 2 is drawn out simultaneously.
As shown in Figure 3, further, described postive stop baffle 9 has two pieces, and the outer circumference surface tube wall that one end of postive stop baffle 9 penetrates syringe extends to syringe inner chamber, and the other end is then outside syringe.Postive stop baffle 9 and syringe inner chamber tube wall contact position are provided with protruding 10, prevent postive stop baffle from shifting out syringe intracavity.When blood sampling uses, although medical personnel firmly pull pitch brace 3 because of carelessness, when piston 2 moves to postive stop baffle place 9 along syringe inner chamber tube wall, postive stop baffle 9 extends to one end of syringe inner chamber to piston 2 one resistances, thus limit the movement of piston 2, ensure that piston 2 can only move in syringe 1.Two pieces of postive stop baffles 9 lay respectively at top and the bottom of syringe outer circumference surface tube wall, have and can hold a spacing distance pointed between postive stop baffle 9 and syringe empennage 11.During blood sampling, point the compartment be between postive stop baffle and syringe empennage, in finger, postive stop baffle and syringe empennage are fixed, and when preventing from taking a blood sample, finger slippage is caused danger.
Above-described embodiment is only the description carried out preferred implementation of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from this utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of this utility model claims.
