Description
Technical field
This utility model relates to a kind of anti-adverse current remaining needle, particularly relates to a kind of anti-adverse current remaining needle that is filled with plug.
Background technology
The inpatient needs transfusion every day, and the stainless pin needle tubing of use can not be stayed in the blood vessel for a long time, for avoiding venipuncture everyday, adopts the way of remaining needle now.Remaining needle is also incited somebody to action intravasation under the guiding of stainless pin needle tubing simultaneously because of its stainless pin needle tubing is surrounded by sleeve pipe, this sleeve pipe outward after penetrating blood vessel, transfers to stainless pin needle tubing sleeve pipe to stay in the blood vessel then and just can keep about 7 days.But nowadays the structural requirement doctor of the catheter block of the remaining needle of Shi Yonging or nurse must have very high proficiency level, otherwise patient blood is easy to flow out external by sleeve pipe after transfering to draw point.Simultaneously, after transfusion finishes, need to extract and change at once infusion connector out calparine cap and seal to avoid blood back flow to external.
Summary of the invention
The purpose of this utility model provides a kind of anti-adverse current remaining needle, and a kind of anti-adverse current remaining needle that is filled with plug particularly is provided.This utility model has solved the problem of using the blood back flow of remaining needle, has remedied the deficiencies in the prior art.
A kind of anti-adverse current remaining needle of the present utility model, remaining needle needle stand (5) is connected with catheter block (4), catheter block (4) front end fixed sleeving (2), in the middle of the sleeve pipe (2) is rustless steel needle tubing (1), and needle stand (5) other end connects exhaust joint (6), and exhaust joint (6) has head protector (7), catheter block (4) rear end has plug to tighten up medicated cap (10), plug tightens up and is filled with plug (9) in the medicated cap (10), and plug (9) has elasticity, can seal automatically and pull out Postductal slit.
As optimized technical scheme:
Wherein, aforesaid a kind of anti-adverse current remaining needle, described catheter block (4) has activity or fixed tab (3).
Aforesaid a kind of anti-adverse current remaining needle, the plug of described catheter block (4) rear end tightens up medicated cap (10) periphery locking tab (17); The locking tab of periphery also can be the taenidium ear.
Aforesaid a kind of anti-adverse current remaining needle, there is fixed core (8) to embed catheter block (4) inner chamber fixed sleeving (2) in the described catheter block (4), fixed core (8) is inserted an end of sleeve pipe (2), and catheter block (4) front end embeds catheter block (4) inner chamber fixed sleeving (2) by fixed core (8) with sleeve pipe (2).Catheter block (4) front end inner chamber also can be fixed on catheter block (4) by bonding with sleeve pipe (2) without fixed core (8).
Aforesaid a kind of anti-adverse current remaining needle has dosing mouth (13) on the described catheter block (4), dosing mouth (13) opening part has dosing mouth helmet (12).
A kind of anti-adverse current remaining needle of the present utility model; usually being with protective sleeve (11) outside sleeve pipe (2) and the rustless steel needle tubing (1) protects; owing to be provided with plug (9) and plug tightens up medicated cap (10); blood can not flow out after extracting rustless steel needle tubing (1), needle stand (5), exhaust joint (6) and head protector (7) out, and transfusion scalp acupuncture or special safety joint can be penetrated plug (9) transfusion.
The beneficial effects of the utility model are:
A kind of anti-adverse current remaining needle of the present utility model, rational in infrastructure, it is easy to repeat transfusion operation, has avoided unexpected generations such as blood back flow, needn't the reuse calparine cap during indwelling, for the doctors and nurses has saved the time, provide convenient.

The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention.
Shown in Fig. 1～8, it is a kind of anti-adverse current remaining needle of the present utility model, it is a kind of anti-adverse current remaining needle that is filled with plug, remaining needle needle stand (5) is connected with catheter block (4), catheter block (4) front end fixed sleeving (2), in the middle of the sleeve pipe (2) is rustless steel needle tubing (1), needle stand (5) other end connects exhaust joint (6), exhaust joint (6) has head protector (7), catheter block (4) rear end has plug to tighten up medicated cap (10), plug tightens up and is filled with plug (9) in the medicated cap (10), and plug (9) has elasticity, can seal automatically and pull out Postductal slit.
Wherein, described catheter block (4) has activity or fixed tab (3).The plug of described catheter block (4) rear end tightens up medicated cap (10) periphery locking tab (17), the locking tab of periphery also can be the taenidium ear, fixed core (8) is arranged in the catheter block (4), fixed core (8) embeds catheter block (4) inner chamber fixed sleeving (2), fixed core (8) is inserted an end of sleeve pipe (2), and catheter block (4) front end embeds catheter block (4) inner chamber fixed sleeving (2) by fixed core (8) with sleeve pipe (2).Catheter block (4) front end inner chamber also can be fixed on catheter block (4) by bonding or welding with sleeve pipe (2) without fixed core (8).Dosing mouth (13) is arranged on the described catheter block (4), and dosing mouth (13) opening part has dosing mouth helmet (12).
