Description
Technical field
The present invention relates to technical field of medical equipment more particularly to a kind of arterial puncture needles.
Background technique
Clinically, critical operation patients or intensive care patient are needed to continue to monitor blood pressure, generallys use invasive blood
Pressure detection, i.e., be inserted into artery using needle of retaining on artery, reconnects artery pressure measuring unit, measures the variation of arterial pressure immediately.Mesh
Preceding common needle of retaining on artery be " BD " company needle of retaining on artery (20G*45mm), this needle of retaining on artery by stainless pin,
Remaining needle and needle tubing casing composition, stainless pin are made of needle body, needle stand and handle, and needle body is common stainless steel needle tubing, compared with
Firmly, front end is needle point, is easy to puncture, and needle stand is located at stainless steel needle tubing tail end, and handle is installed on needle stand；Remaining needle is led by remaining needle
Pipe, catheter block and bloodstream blocking valve group at, indwelling needle catheter is lucite pipe, softer, be suitble to long period indwelling in blood vessel,
Indwelling needle catheter is placed on outside stainless steel needle tubing, and the about short 1mm of more stainless draw point pipe, bloodstream blocking valve is installed on catheter block, passes through
It, which slides back and forth, opens or closes catheter block bore passages；Needle tubing casing is placed on outside indwelling needle catheter, is omited than stainless steel needle tubing
It is long, for protecting indwelling needle catheter and stainless steel needle tubing.The combination of stainless pin, remaining needle and needle tubing casing is by stainless steel
Indwelling needle catheter is inserted into the catheter block inner cavity that needle tubing passes through remaining needle, and needle stand inserts in catheter block tail end, and handle is held on remaining needle
Needle stand two sides, needle tubing casing is placed on outside indwelling needle catheter.
In use, removing needle tubing casing, stainless steel needle tubing is routinely inserted into arteries together with indwelling needle catheter,
Bloodstream blocking valve is placed in open position, if there is blood back in catheter block channel, it is dynamic to illustrate that the syringe needle of stainless steel needle tubing has been inserted into
Arteries and veins blood vessel extracts stainless pin out, closes bloodstream blocking valve blocking blood flow, and catheter block tail end is surveyed by connecting tube and artery and is pressed
It sets connected, so that it may the variation of observation intra-arterial blood pressure immediately.
Although however, this needle of retaining on artery have following defects that 1) close bloodstream blocking valve can with blocking blood flow,
Blood can not be entirely prevented to overflow from catheter block tail end in actual operation, after extracting stainless pin out, close bloodstream blocking
It will cause spray blood in time difference before valve, easily cause the blood of pollution, especially patients with infectious diseases；2) bloodstream blocking valve is logical
It crosses to slide back and forth and realizes that catheter block bore passages open and close, be easy to cause moment impact to remaining needle in sliding, forward
It is easy that it is made deeply to cause patient grieved when promotion, is easy that indwelling needle catheter is made to deviate from arteries when pulling back；3) stainless
When steel needle is inserted into arteries together with indwelling needle catheter, if bloodstream blocking valve is in the open position, the two is easily separated from, and is not easy to insert
Enter, if bloodstream blocking valve is in the closed position, micro-strain can occur for stainless pin under bloodstream blocking valve action, influence to make
With.
In view of the above-mentioned problems, a kind of the present invention provides structures arterial puncture needle simple, easy to use, passes through setting rubber
The crushing block and pressurizing unit of glue material matter, realize the blocking in catheter block channel, and indwelling needle catheter and puncture needle tubing are inserted into artery
When, crushing block is compressed by pressurizing unit, indwelling needle catheter and puncture needle tubing are not readily separated, when puncturing needle tubing extraction, nothing
Pressurizing unit need to be unclamped, directly be extracted out, under pressure, the sebific duct in the middle part of crushing block can be flattened, and realize conduit
The blocking in seat channel, avoids the generation of spray blood；Pressurizing unit uses the synchronization pressing mechanism of special designing, top board and pushing
Plate is synchronous to be drawn close to crushing block middle part, and needle tubing is punctured when avoiding occluding catheter seat channel and is deformed under pressure；Institute
It states pressurizing unit and compression is realized by screw rod, realize bloodstream blocking, avoid when opening and closing catheter block channel to remaining needle
Cause moment impact.
