When row punctures, owing to the pressure in pin chamber is unchanged, there is the problem being not readily observed blood back.Especially for systemic circulation
Oligemia, the patient of hypoproteinemia edema, owing to circulating blood volume is not enough, nutriture is poor, make the blood vessel of patient subside,
Blood vessel does not fills, and causes being difficult to observe blood back when disposing remaining needle, affects puncture success rate.
Utility model content
Technical problem to be solved in the utility model is to provide the remaining needle of a kind of sensitive blood-return.
This utility model solves the remaining needle of the technical scheme is that sensitive blood-return of its technical problem, including needle stand
And puncture needle, one end of described needle stand is indwelling flexible pipe, forms pin chamber, pin chamber and indwelling soft pipe connection in needle stand, and pin intracavity sets
Putting batching pig, needle stand is that transparent material is made, and puncture needle is through batching pig and inserts in indwelling flexible pipe, needle stand is also connected with extend
Manage, and the pin chamber between extension tube with batching pig and indwelling flexible pipe connects；On needle stand outside described batching pig, positioning groove is set,
The direction of positioning groove is consistent with the length direction in pin chamber, arranges the position adjuster being connected with batching pig at positioning groove.
After indwelling needle, stirring position adjuster, drive batching pig to move, pin cavity pressure reduces, and contributes to blood back, so
Blood back situation can be observed easily, to judge whether puncture needle and indwelling flexible pipe puncture to Ink vessel transfusing.
Further, described positioning groove length on pin cavity length direction is less than batching pig on pin cavity length direction
Length, and position adjuster is positioned at any one end of positioning groove, and batching pig all can cover positioning groove.
Further, described pin chamber is cylindrical, and batching pig is cylindrical；One end connecting puncture needle of described puncture needle
Seat, Paracentesis needle holder connects single-blade needle handle.
Moreover, the rectangular shape of described positioning groove, the length direction with pin chamber of positioning groove is consistent, positioning
The another side of groove is arc-shaped edges, and arc-shaped edges is located close to the side of indwelling flexible pipe.
Position adjuster is snapped at the arc-shaped edges of positioning groove, the position of batching pig can be fixed, and can be by single-blade pin
Position adjuster is snapped in the arc-shaped edges of positioning groove by the rotation of handle.
Further, described puncture needle arranges through hole, when the needle point of puncture needle aligns with described indwelling hose tip
Time, described through hole pin intracavity between batching pig and indwelling flexible pipe.
The beneficial effects of the utility model are: before carrying out retained needle puncture, stir position adjuster and make batching pig be located close to
Indwelling flexible pipe side；After indwelling needle, stirring position adjuster to away from indwelling flexible pipe side, pin cavity pressure reduces, and contributes to
Blood back, can observe blood back situation significantly, be favorably improved puncture success rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the remaining needle of this utility model sensitive blood-return.
Fig. 2 is the schematic diagram of the remaining needle adjustment batching pig of this utility model sensitive blood-return.
Parts, position and numbering in figure: needle stand 10, pin chamber 11, indwelling flexible pipe 12, extension tube 13, puncture needle 21, puncture
Needle stand 22, single-blade needle handle 23, through hole 24, batching pig 31, position adjuster 32, positioning groove 33.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the remaining needle of this utility model sensitive blood-return, including needle stand 10 and puncture needle 21, described needle stand 10
Left end be indwelling flexible pipe 12, form pin chamber 11 in needle stand 10, pin chamber 11 connects with indwelling flexible pipe 12, arranges isolation in pin chamber 11
Plug 31, needle stand 10 is made for transparent material, and puncture needle 21 is through batching pig 31 and inserts in indwelling flexible pipe 12, the end of puncture needle 21
End connecting puncture needle seat 22, Paracentesis needle holder 22 connects single-blade needle handle 23.Extension tube 13, and extension tube 13 it is also connected with on needle stand 10
Connecting with pin chamber 11, specifically, extension tube 13 connects near the pin chamber 11 of indwelling flexible pipe 12 side with batching pig 31.
Arranging positioning groove 33 on needle stand 10 outside batching pig 31, positioning groove 33 is in " one " shape, and the side of positioning groove 33
To consistent with the length direction in pin chamber 11, the position adjuster 32 being connected with batching pig 31 is set at positioning groove 33.After indwelling needle,
Stir position adjuster 32 to away from indwelling flexible pipe 12 side, drive batching pig 31 to move accordingly, it is possible to decrease the pressure in pin chamber 11, i.e.
Form negative pressure in pin chamber 11 between batching pig 31 and indwelling flexible pipe 12, contribute to blood back, so can observe back easily
Blood situation, to judge whether puncture needle 21 and indwelling flexible pipe 12 puncture to Ink vessel transfusing, improves puncture success rate.
In order to avoid positioning groove 33 affects the seal in pin chamber 11, the positioning groove 33 length on the length direction of pin chamber 11 is low
In the batching pig 31 length on the length direction of pin chamber 11, and position adjuster 32 is positioned at any one end of positioning groove 33, batching pig
31 all can cover positioning groove 33.
Above-mentioned positioning groove 33 in addition in " one " shape, positioning groove 33 also can rectangular shape, positioning groove 33 and pin
The length direction in chamber 11 is consistent, and the another side of positioning groove 33 is arc-shaped edges, and arc-shaped edges is located close to the side of indwelling flexible pipe 12,
As shown in Figure 2.Being batching pig 31 below positioning groove 33, and pin chamber 11 is cylindrical, batching pig 31 is cylindrical.
Before patient disposes remaining needle, position adjuster 32 is located close to the side of indwelling flexible pipe 12, after indwelling needle, Xiang Yuan
Stir position adjuster 32 from indwelling flexible pipe 12 side, reduce the pressure in pin chamber 11, blood back situation can be observed easily, if just
Often blood back, can reverse position adjuster 32 in situ.In order to preferably consolidate position adjuster 32 and batching pig 31, the arc-shaped edges of positioning groove 33
Side away from indwelling flexible pipe 12 has the arc limit of protrusion, and position adjuster 32 so can snap in the arc-shaped edges of positioning groove 33, it is to avoid
Middle batching pig 31 is used to horizontally slip.Furthermore, it is possible to position adjuster 32 is snapped in positioning groove 33 by the rotation by single-blade needle handle 23
In arc-shaped edges, convenient and laborsaving.
For the ease of observing blood back, puncture needle 21 arranges through hole 24, when needle point and the described indwelling flexible pipe of puncture needle 21
During 12 most advanced and sophisticated alignment, in the through hole 24 pin chamber 11 between batching pig 31 and indwelling flexible pipe 12.
