Description
Technical field
The present invention relates to medical instruments field, specifically a kind of protection type arterial puncture detaining needle.
Background technology
Critical operation patients or intensive care patient are needed to monitor blood pressure in real time, generally use invasive monitoring of blood pressure,
Arterial puncture needle is used to be inserted into artery, then is connect with artery pressure measuring unit.Since arterial pressure is higher, when being punctured,
Blood is often sprayed from needle tubing or hydraulic interface, is polluted, and the probability that iatrogenic disease is propagated is increased.In addition, working as needle core
When being exited from needle tubing, needle point has certain danger, if individually removing processing needle point, can waste time and energy.
Invention content
In order to solve above-mentioned defect existing in the prior art, the present invention provides a kind of protection type arteriopuncture indwellings
Needle, can anti-Hemostatic Oral Liquid spray, while when extracting needle core out, needle tip protection sleeve covers needle point automatically, eliminates safe hidden trouble.
The technical solution adopted by the present invention：A kind of protection type arterial puncture detaining needle, including remaining needle outer tube, needle core and
Needle stand is provided with pressure measurement interface on the remaining needle outer tube, and inside remaining needle outer tube, the right side of pressure measurement interface is equipped with ring
Shape block body；It is cased with rubber stopper and needle tip protection sleeve on the needle core；The needle core is equipped with expanded letter close to the side of needle point；Institute
The position for the rubber stopper stated is on the left of pressure measurement interface；The needle tip protection sleeve is passed through from the hollow space of annular block body；It is described
Needle tip protection sleeve include pedestal and pinch；The pedestal is equipped with the hole passed through for needle core, and the width of expanded letter is more than the hole
Diameter.
Preferably, the needle tip protection sleeve is made of a pedestal and the L-shaped pinch of two panels, and the edge of pinch, which is equipped with, to be prevented
The bending part that only needle point is pierced by.
Preferably, the pressure measurement interface and remaining needle outer tube are at 15 degree of angles.
Preferably, the expanded letter is by being locally stamped and formed out needle core.
Beneficial effects of the present invention：Rubber stopper is installed on needle core, during extracting needle core out, the rubber under the promotion of expanded letter
Leather plug follows needle core to be moved to right side on the left of pressure measurement interface, opens pressure measurement interface, so that blood flow is flowed to pressure measurement interface, in this phase
Between can connect pressure measuring unit in advance, just can anti-Hemostatic Oral Liquid spray suddenly.When rubber stopper is moved at block body, can not continue to
Move right, continue at this time outside drawn needle core under the effect of the pressure rubber stopper center gap expand so that expanded letter is passed through, wait for needle core
After extraction, since rubber stopper is flexible, the gap at center is closed automatically prevents blood from overflowing.Needle tip protection sleeve is disposably to make
With when protection is not triggered, needle tip protection sleeve is arranged in the middle vacancy of block body, when needle core is inserted into, after two pinches are softened
Width be more than block body hollow space diameter, at this time needle tip protection sleeve will not be extracted；When needle point is drawn to needle tip protection sleeve
When, pinch is clipped together under elastic reaction, needle point is clamped protection in dogleg section, as needle point exits remaining needle together
Outer tube.Since the width of expanded letter is more than the diameter in hole on needle tip protection sleeve pedestal, so needle point cannot be from needle tip protection sleeve
Bottom is extracted out, and due to being equipped with double-bending structure at needle tip protection sleeve pinch, needle point can not be also pierced by the top of needle tip protection sleeve,
Therefore this protection is very reliable, and materials are extremely saved.

Specific implementation mode
As shown in Figure 1, a kind of protection type arterial puncture detaining needle, including remaining needle outer tube 1, needle core 2 and needle stand 3,
It is characterized in that：It is provided with pressure measurement interface 6 on the remaining needle outer tube 1, inside remaining needle outer tube 1, the right side of pressure measurement interface 6
Side is equipped with annular block body 7；It is cased with rubber stopper 4 and needle tip protection sleeve 5 on the needle core 2；The needle core 2 is close to the one of needle point
Side is equipped with expanded letter 8；The position of the rubber stopper 4 is in 6 left side of pressure measurement interface；The needle tip protection sleeve 5 is from annular block body 7
Hollow space passes through；The needle tip protection sleeve includes pedestal 5.2 and pinch 5.1；The pedestal is equipped with and is passed through for needle core 2
Hole, the width of expanded letter 8 is more than the diameter in the hole.
In the present embodiment, the pressure measurement interface 6 and remaining needle outer tube 1 are at 15 degree of angles；The expanded letter 8 uses
The mode of the local punching press of needle core 2 is formed.
When in use, artery is punctured with needle core 2, blood enters remaining needle outer tube 1, cannot by the obstruction of rubber stopper 4
Outflow.Pressure measuring unit is connect with pressure measurement interface 6, then slowly extracts needle core 2 out, rubber stopper 4 is by left-hand under the promotion of expanded letter 8
It moves right, blood is made to enter pressure measurement interface 6, polluted from the ejection of pressure measurement interface 6 so as to avoid blood.
If needle core 2 is not exclusively extracted out from remaining needle outer tube 1, pressure measurement can be influenced as a result, common arterial puncture needle will
After needle core 2 is extracted out, since needle point does not have protective device, security risk can be brought, therefore, we devise a kind of needle point guarantor
Sheath 5, as shown in Fig. 2, being made of a pedestal 5.2 and the L-shaped pinch of two panels 5.1, the edge of pinch 5.1, which is equipped with, prevents needle point
The bending part 5.3 being pierced by, side are X-shaped, and needle tip protection sleeve 5 is metal material, is triggered using the elasticity of sheet metal itself
Protection act.When protection does not trigger, i.e., when needle core 2 passes through needle tip protection sleeve 5, two pinches 5.1 of needle tip protection sleeve 5 are supportted
Width after opening is more than the diameter of 7 hollow space of annular block body, and needle tip protection sleeve 5 is arranged in the middle vacancy of annular block body 7, at this time
Needle tip protection sleeve 5 will not be extracted；When needle point is drawn in needle tip protection sleeve 5, pinch 5.1 is clipped in one under elastic reaction
It rises, needle point is clamped into protection in dogleg section, as needle point exits remaining needle outer tube together.Since the width of expanded letter 8 is big
Diameter in hole on needle tip protection sleeve pedestal 5.2, so needle point cannot be extracted out from the bottom of needle tip protection sleeve 5, since needle point is protected
Double-bending structure is equipped at the pinch 5.1 of sheath 5, needle point can not be also pierced by from the top of needle tip protection sleeve 5, that is to say, that needle point
The defencive function of protective case 5 will tightly wrap needle point once triggering, defencive function with needle core 2 extraction automatic trigger,
It is simple and convenient, and cost is very low.
