Abstract
The invention relates to a novel artery puncture trocar, which comprises a needle tube and a core, wherein one end of the core is connected with a detachable handle, and a core cap is connected on the handle; the needle tube can be penetratively sleeved outside the core in a replaceable way, and tip of the core is exposed out of the needle tube. The novel artery puncture trocar has the beneficial effects of high puncture success ratio, and safer and more convenient puncture.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of novel arterypuncture trocar that can be used for radial artery and femoral artery puncture.
Background technology
Monitoring direct arteriotony at present clinically selects for use radial artery puncturing to put pipe often, puncture needle is the 20GA trocar, when radial arterys such as running into massive hemorrhage, urgent rescues can't touch or dissecting aneurysm etc. when needing opening artery of lower extremity (femoral artery often), because of the femoral artery position darker, part in the 20GA trocar intravasation is limited, situation such as the puncture needle slippage usually occurs, be difficult to fix, and do not have special-purpose femoral artery puncture pin at present.It is fine also usually to run into the nook closing member blood back in addition in puncture, can't insert blood vessel and needle tubing is damaged, scared, the nook closing member needle tubing can only be extracted together and puncture again, so both waste the time, reduced the success rate that the clinician punctures, also increased misery, even increased the weight of the state of an illness to patient.
Summary of the invention
The present invention needs the problem that punctures again under the damaged situation of needle tubing in the time of will solving existing puncture needle and use, a kind of novel arterypuncture trocar that need not to puncture again under the damaged situation of needle tubing is provided.
Technical scheme of the present invention:
A kind of novel arterypuncture trocar comprises needle tubing, nook closing member, it is characterized in that: an end of described nook closing member is connected with dismountable needle handle, is connected with the nook closing member medicated cap on the described needle handle; Described needle tubing is removable to be set on outside the nook closing member, and the needle tip of described nook closing member exposes outside needle tubing.
Further, described needle tubing diameter is 1.1mm, and its length is 48mm-63mm.
Further, described needle tubing is than the short 1.5mm of nook closing member.
Technical conceive of the present invention is that needle tubing is made plurality of specifications, and needle tubing length can be 48mm, 53mm, 58mm, 63mm.The puncture needle slippage that the needle tubing of different length has usually run into when having solved femoral artery puncture, be difficult to fixed problem, make femoral artery puncture safer, more convenient.
Because nook closing member and needle handle are dismountable, the nook closing member blood back is fine when running in puncture, and needle tubing, can be extracted needle handle can't insert blood vessel the time because of damaged, scared from nook closing member, the needle tubing of breakage is also extracted, newer needle tubing is worn nook closing member and insert blood vessel outward again.Under the situation of needle tubing breakage, the patient need not to be punctured again once again, palliates the agonizing sufferings to the patient like this.
The present invention is the arterial cannula pin that is used for puncturing when being used in needs monitoring patients' such as Anesthesia Department or Intensive Care Therapy, emergency department direct blood pressure.
Effect intentionally of the present invention: the puncture success rate height, it is safer, more convenient to puncture.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a needle tubing structural representation of the present invention.
Fig. 3 is a nook closing member structural representation of the present invention.
The specific embodiment
With reference to Fig. 1-3, a kind of novel arterypuncture trocar comprises needle tubing 1, nook closing member 2, and an end of described nook closing member 2 is connected with dismountable needle handle 3, is connected with nook closing member medicated cap 4 on the described needle handle 3; Described needle tubing 1 removable being set on outside the nook closing member 2, the needle tip of described nook closing member 2 exposes outside needle tubing 1.
Described needle tubing 1 diameter is 1.1mm, and its length is 48mm-63mm.
Described needle tubing 1 is than nook closing member 2 short 1.5mm.
Technical conceive of the present invention is that needle tubing 1 is made plurality of specifications, and needle tubing 1 length can be 48mm, 53mm, 58mm, 63mm.The puncture needle slippage that the needle tubing of different length has usually run into when having solved femoral artery puncture, be difficult to fixed problem, make femoral artery puncture safer, more convenient.
Because nook closing member 2 and needle handle 3 are dismountable, nook closing member 2 blood backs are fine when running in puncture, and needle tubing 1, can be extracted needle handle 3 can't insert blood vessel the time because of damaged, scared from nook closing member 2, the needle tubing 1 of breakage is also extracted, newer needle tubing 1 is worn the nook closing member 2 outer blood vessels of inserting again.Under the situation of needle tubing 1 breakage, the patient need not to be punctured again once again, palliates the agonizing sufferings to the patient like this.
The described content of this description embodiment only is enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
Claims (3)
1. a novel arterypuncture trocar comprises needle tubing, nook closing member, it is characterized in that: an end of described nook closing member is connected with dismountable needle handle, is connected with the nook closing member medicated cap on the described needle handle; Described needle tubing is removable to be set on outside the nook closing member, and the needle tip of described nook closing member exposes outside needle tubing.
2. a kind of novel arterypuncture trocar according to claim 1, it is characterized in that: described needle tubing diameter is 1.1mm, and its length is 48mm-63mm.
