Description
Technical field
The present invention relates to a kind ofly medium introduced intravital apparatus, particularly a kind of needle stand and installation method thereof.
Background technology
The applicant is once at a kind of remaining needle with protective sleeve of first to file, and the structure of its needle stand such as accompanying drawing 1: include pedestal 1, needle guard 2 and needle tubing 3, needle tubing 3 is plugged in the needle guard 2; And it is affixed with it; Needle guard 2 includes rod member 21 and back-end component 22, rod member 21 and back-end component 22 Construction integrations, and an end of pedestal 1 is an open end 11; The other end is bottom 12; Back-end component 22 snaps onto on the bottom 12 of pedestal 1, and is closely affixed with pedestal 1, is installed with a hand steered wing 4 on the pedestal 1.During installation, for the purpose of health and safety, needle tubing can not pass pedestal; In addition because the back-end component of needle guard is greater than the bottom opening of pedestal, so this needle guard can't by pedestal open end 11 places toward the bottom 12 directions cover insert; When needle stand was installed, at first the needle guard of Construction integration was got into by the bottom of pedestal, snapped onto on the bottom of pedestal until the back-end component of needle guard; Pipe end with needle tubing is plugged on the hollow rods of needle guard then; Carry out a glue then, glue is injected hollow joint between needle tubing pipe end and the needle guard rod member, needle tubing can firmly be fixed on the needle guard.
This technological weak point is: after 1, the operation of some glue must snap onto on the pedestal bottom at the needle guard of Construction integration, the pipe end of needle tubing gets into needle guard just can carry out, because hollow joint is very little between the pipe end of needle tubing and the needle guard; Need high technology during point glue; In case glue falls into needle guard with exterior portions, get between needle guard and other protective sleeves or the pedestal, will cause this finished product to be scrapped; Therefore such needle stand yield rate is very low, and very inconvenience is installed; 2, have a dial on the needle tubing, this dial is a rake angle section of needle tubing, dial hollow, and dial is a needle point along the outermost end of needle tubing.Because the medical science difference of various places, various countries uses the maneuver of pin inconsistent, therefore need dial and be positioned at the hand steered wing on the pedestal different angles of hoping for success as required, parallel or vertical, or angled, to satisfy local instructions for use; But when needle stand was installed, needle guard had been fixedly connected on the pedestal, because the needs of accuracy are installed; Needle tubing and pedestal all must be in a fixed position; Therefore dial can only be connected with needle guard with the angle that is fixed in the hand steered wing, and can't change the angle of the dial and the hand steered wing as required, if the angle that conversion is installed; Then need carry out the big modification on the equipment to whole flow process; Not only cost is high, and very complicated, therefore is difficult to produce different needle stands according to the geographic demand of country variant.
Invention constitutes
The objective of the invention is to overcome weak point of the prior art and a kind of easy for installation, needle stand and installation method thereof that yield rate is improved greatly is provided.
One of the present invention's purpose realizes through following approach.
A kind of needle stand includes pedestal, needle guard and needle tubing, and needle guard includes rod member and back-end component; Needle tubing is plugged in the rod member, and affixed with it, and an end of pedestal is an open end; The other end is the bottom, and pedestal contains the periphery that is contained in rod member, and its structural feature is; Rod member and back-end component divide body structure, and back-end component is connected an end of rod member and the bottom that back-end component is nested in pedestal, and needle tubing is extended by the open end of pedestal outward.
Movable connection between the rod member of branch body structure and the back-end component; So just can rod member be connected earlier with needle tubing and some glue; The rod member that will have needle tubing again stretches into pedestal by the open end of pedestal; Make an end of rod member pass the bottom of pedestal, then with the back-end component retaining ring at the rod member that stretches out the pedestal bottom one end, at last the needle guard that connects is embedded into this mode of pedestal bottom with the back-end component button and accomplishes with pedestal and be fixedly connected at last.Because the rod member of needle guard and the branch body structure of back-end component; Make rod member can isolate pedestal carry out earlier with needle tubing be connected and the some glue; Further connect back-end component and pedestal again, the operation of invocation point glue is become simply, make things convenient for, simultaneously; Even the excessive miscellaneous part that also can not have influence on needle stand again of glue during point glue, the yield rate of this needle stand is just improved greatly like this.
On the other hand, because rod member and back-end component are a minute body structure, with before rod member is connected, can the dial that be connected the needle tubing on the rod member be rotated to suitable angle on demand, and then back-end component is connected with pedestal at back-end component.When needle tubing being carried out the angle rotation, need not operate, thereby need not handle greatly yet process equipment to pedestal, simple, convenient.
The present invention can further be specially:
Back-end component is a kind of revolving body.Specifically can be:
Being a kind of cylindrical shape, can also be a kind of cone shape.
Revolving body is meant at two points of the two ends of revolving body hypothesis; And 2 company's being aligneds pass revolving body; Revolving body is a center of rotation with this line; When its each partial rotation is to fixing position when rotated all is the same shape, and its feature is that the both sides of centrage are for symmetry, so revolving body basically all is symmetric.And have identical revolution shape opening on the bottom of the corresponding pedestal of back-end component, be convenient to back-end component is connected with the pedestal bottom, can adopt viscose glue to be connected and sealed, also can adopt the button embedding to connect.Can be with the whole embedding pedestal of back-end component bottom; The bottom of pedestal will surround the periphery of whole back-end component like this; The part that also can be back-end component is installed in the opening of pedestal bottom; Be inverse-T-shaped such as back-end component, the bottom is by touching the outer surface in the pedestal bottom, and vertically the part button embeds in the atrium of bottom.
Back-end component further can be specially:
Upper bottom portion has an annular boss; Its area is greater than back-end component upper bottom surface area, and corresponding inboard, pedestal bottom has step in, when back-end component inserts the pedestal bottom; Because the external diameter of annular boss is greater than the internal diameter of interior step, the annular boss embedding leans against on the interior step of bottom.
After can preventing that like this back-end component is fit into the pedestal bottom, produce backward the danger that (promptly along pedestal to the bottom direction) slides.
Lower bottom part is a kind of plane; The area of plane is greater than back-end component bottom surface area, and the outer evagination is in the edge of lower bottom part, and the outside of corresponding pedestal bottom has an outer step; When back-end component inserted the pedestal bottom, this plane tightly was attached to outside this bottom on the step.
After can preventing that like this back-end component is fit into the pedestal bottom, produce the danger of (being the needle tubing direction) slip forward.
When the upper and lower bottom of back-end component all has greater than the long-pending convex surface of back-end component respective bottom surfaces; Be that upper bottom portion has annular boss; Lower bottom part has the plane of evagination; Make back-end component be " worker " font along the section of axis direction like this, the convex configuration at the upper and lower end can be buckled on the pedestal bottom, prevents that back-end component from producing moving forward or backward on the pedestal bottom.
As preferably, preferably a kind of cone shape of back-end component, the upper bottom portion area is less than the lower bottom part area, and upper bottom portion has circular boss, and lower bottom part is a kind of circular compacting plane.
Because shaft section diminishes to upper bottom portion along lower bottom part gradually, like this can be so that back-end component be pushed in the inner chamber of pedestal bottom, the structure at the upper and lower end can prevent snapping go into the back-end component of pedestal bottom produce in the bottom axially movable.
Back-end component can also be a kind of non-revolved body.Specifically:
When back-end component was a kind of cylinder or a kind of cone, its cross section can be a kind of circle, can also be a kind of circle of flat-cut.
Non-revolved body is relative revolving body, after non-revolved body receives peripheral the coating, can't rotate.The cross section of back-end component is as a kind of circle of flat-cut; For a kind of circle lacks the shape plane; Cylinder or the cone that is to say back-end component vertically by flat-cut a part, form a tangent plane, tangent plane is without the cylinder axle center; But vertical with the axle center or angled, the area of barbed portion is less than remaining flat-cut circle.This just makes that having one on the back-end component lacks face, and is same, also should have same scarce face on the bottom of pedestal, after the back-end component correspondence is connected to the pedestal bottom, just is fixed on the same position like this, can't rotate again.
Back-end component can also be to be a kind of polygon cylinder.Like triangle cylinder, square cylinder etc., the non-revolved body of this type also can guarantee after buckling into the bottom of pedestal, can not rotate.
Back-end component can also further be specially:
The back-end component lower bottom part is a kind of notched compacting plane, and this breach is positioned at the planar end edgewise of compacting.
Like this, with back-end component with when rod member is connected, can the dial of needle tubing be aimed at this breach; At back-end component with when pedestal is connected; Rotate this breach, breach is rotated to the angle that becomes to need with the hand steered wing of pedestal, again back-end component and pedestal are fastenedly connected.Further realized producing on demand the requirement of the needle stand of dial and hand steered wing different angles, this simple in structure, convenient.
Above-mentioned breach can be a kind of " V " v notch v, can also be a kind of " W " v notch v, can also be a kind of straight line breach, is positioned on the plane of flat-cut.
The form of breach can be provided with according to the characteristics of producing, but as preferred, the straight line breach on preferably a kind of circle; Because in corresponding angle; When the breach and the hand steered wing carry out the angle processing, be a plane as the hand steered wing, straight line and interplanar angle are confirmed more easily.
Back-end component can further be specially with being connected of rod member:
Back-end component is connected with rod member through a kind of connector.This connector can be a kind of viscose glue, can also be a kind of fastener, fastens back-end component and rod member respectively, to realize being fastenedly connected of the two.
Can also be:
Back-end component has an inner groovy, and the opening part of this inner groovy is the upper bottom portion of back-end component.
Like this, an end of rod member can insert in this inner groovy, thereby is connected with back-end component.
The inner groovy of back-end component is bar shape, has the ring-shaped groove that a circle concaves on the cylinder, and an end of the rod member that is connected with this back-end component has the annular boss of a circle evagination, but in the ring-shaped groove of this annular boss inlay card in the back-end component inner groovy.
Can realize that like this back-end component is connected with no medium between the rod member, does not promptly need other connector to realize the connection between the two.This structure is very easy, and it also is convenient, simple being operatively connected.
This inner groovy can also further be specially:
The back-end component inner groovy is a kind of cylinder, has a straight line breach on its cross section, also has a straight line breach on the cross section of rod member one end that is connected with this inner groovy.
Like this, on the end of back-end component inner groovy and rod member tangent plane is arranged all, during installation, the breach tangent plane of the two needs corresponding the installation, and back-end component or rod member after can preventing like this to install relatively rotate.
The breach of the cylinder of back-end component or cone, lower bottom part and inner groovy is unidirectional mounting plane; Or the breach of the cylinder of back-end component, lower bottom part is unidirectional mounting plane, but is axial symmetrical distribution with the breach face of inner groovy.
So-called unidirectional mounting plane, the breach plane of the two is a parallel plane in other words.Being convenient to carry out in the installation process correspondence like this distributes.
One end of rod member has a cavity, and a plurality of muscle bodies are arranged in the cavity, is the circumference rule and distributes, and an end of muscle body points to the center of circle, and needle tubing is installed in this cavity.
This cavity is used to install needle tubing, and a plurality of muscle bodies entad extend, and forms a centre point, and the needle tubing of insertion is positioned at this centre point, can under the elasticity compacting of muscle body, tightly be fixed in the inner chamber of this rod member.
The present invention can also be specially:
Also have the protective sleeve of being made up of a plurality of sleeves not of uniform size and belled in the inner chamber of pedestal, rod member is arranged in the minimum telescopic axis intracavity of protective sleeve, after these a plurality of sleeves spread apart, will coat whole needle tubing.
The protective sleeve that these a plurality of sleeves are formed is compressive state when mounted, and after needle set used, this protective sleeve spread apart descending or ascending successively; Like this; Protective sleeve has just extended the length of needle stand, is enough to coat whole needle tubing, reaches protective effect.
In such structure, because the installing space of rod member is very little, if give me a little glue by original technology; Then can make gluing process more difficult, yield rate is lower, and the advantage of the present invention in such structure also has been described thus; That is: after rod member and back-end component divided body structure, rod member can be isolated the belled needle stand of this complicacy, was connected with needle tubing and some glue in advance; And then the inner chamber that passes the minimum cover of protective sleeve connects back-end component with tail end, makes gluing process more simple, and yield rate also improves greatly.

The rod member that 5, will connect needle tubing is stretched in the pedestal inner chamber by the open end of pedestal, and exposes the other end of rod member from the bottom of pedestal,
6, back-end component and rod member one end that exposes the pedestal bottom are fastenedly connected,
7, the back-end component after will connecting and the bottom of pedestal are fastenedly connected.
Because rod member is connected with the split of back-end component, makes needle tubing to carry out elder generation's point glue in the space beyond the pedestal cavity, and then be connected with back-end component with rod member; During this sampling point glue; Just need not consider whether glue falls into other positions of needle stand, perhaps fall into miscellaneous part that needle stand is connected on, in case because glue is excessive on needle stand or miscellaneous part the time; Therefore will cause whole needle set to be scrapped, to such an extent as to such installation method will improve the yield rate of needle stand needle set greatly.
In the prior art, rod member and back-end component are Construction integrations, because back-end component is very little; For whole needle stand or needle set is not very important, so those skilled in the art carries out Construction integration with itself and rod member, produces and makes with convenient; In the course of time, just formed a kind of technological prejudice, and those skilled in the art broken through should technology prejudice; Divide body structure with rod member and back-end component, make and carry out other installations again by needle tubing and the rod member mounting points glue of can going ahead of the rest; Brought great technique effect: the yield rate of needle stand or needle set is improved greatly, simple installation, and improved yield rate greatly.
Method of the present invention can also further be specially:
Back-end component is a kind of cone; Have a circular boss on its upper bottom portion, lower bottom part is the plane that a kind of outer protrudes in cone, and the plane is that the circle that has the straight line breach lacks the shape plane; One side of cone has the plane breach, and this plane breach is parallel with the straight line breach of lower bottom part.
Like this, said method also comprises the steps:
1, when back-end component is connected with rod member, the needle tubing dial that is connected on the breach on the back-end component and the rod member is alignd, the straight line parallel that makes breach is in dial,
2, the hand steered wing on breach on the back-end component and the pedestal is carried out angular alignment, after the angle that the breach on the back-end component rotates to the hand steered wing become to need, the bottom of back-end component and pedestal is fastenedly connected.
In the existing technology, back-end component and rod member Construction integration, needle tubing is with before rod member is connected; Back-end component has been connected the pedestal bottom; Therefore can't change the angle between needle tubing dial and the hand steered wing of pedestal again, and the branch body structure of employing the present invention's one back-end component and rod member, then can be at needle tubing with after rod member is connected; Again to the needle tubing dial and and the hand steered wing of pedestal between angle adjust, just can be according to the needle stand that requires the production different angles of producing needle set.
In sum; The present invention compares prior art and has following advantage: the rod member and the back-end component of needle guard divide body structure, like this rod member can isolate pedestal carry out earlier with needle tubing be connected and the some glue, further connect back-end component and pedestal again; The operation of invocation point glue is become simply, make things convenient for; Simultaneously, even point excessive miscellaneous part that also can not have influence on needle stand again of glue during glue, the yield rate of this needle stand is just improved greatly like this.On the other hand; Because rod member and back-end component are a minute body structure, at back-end component with before rod member is connected, to the needle tubing dial and and the hand steered wing of pedestal between angle adjust; Just can increase the demand of producing according to the needle stand that requires the production different angles of producing needle set.
