Embodiment
Present invention is described in detail with reference to Figure of description and specific embodiment：
As shown in Figure 2 and Figure 3, it is a kind of backpulsing arterial puncture needle provided by the invention, including puncture needle 1 and indwelling
Pin 2, the puncture needle 1 include puncturing needle tubing 1-1, needle tubing seat 1-2 and are arranged in needle tubing seat 1-2 and with puncturing needle tubing 1-1
The chamber 1-3 being connected, the remaining needle 2 include indwelling needle catheter 2-1, the catheter block 2-2 that is connected with indwelling needle catheter 2-1 with
And the check (non-return) valve 2-3 in catheter block 2-2 cavitys is arranged at, described one end for puncturing needle tubing 1-1 is connected with needle tubing seat 1-2, institute
State and puncture the needle tubing 1-1 other end and be placed on that indwelling needle catheter 2-1 is interior and termination is placed on indwelling needle catheter through check (non-return) valve 2-3
Outside 2-1, the needle tubing seat 1-2 is made of clear material or provided with the transparent window that can be seen inside chamber 1-3, the chamber 1-
The sliding part 3 that can be slidably reciprocated on the direction that chamber 1-3 interior edges blood flows into is slidably connected in 3, is gone back in the chamber 1-3
Provided with for making sliding part 3 keep the elastomeric element 4 of a certain initial position in chamber 1-3.Sliding part 3 is in chamber 1-3
Before initial position refers to that blood is introduced into chamber 1-3, the position of sliding part when elastomeric element 4 is in nature elongation state.
As shown in Fig. 2 in order that sliding part can be slided preferably in chamber, the sliding part 3 includes being slidably connected to
Sealing device 3-1 in the chamber 1-3 and vibrating membrane 3-2 being arranged on sealing device 3-1, the elastomeric element 4 are connection
Return spring between vibrating membrane 3-2 and chamber 1-3 ends, the chamber 1-3 ends are connected provided with more than one with the external world
Logical gas channel 1-3-1.The elastomeric element 4 can also use flexure strip, elastic threads etc..The chamber 1-3 ends are
The other end of end opposite side is flowed into positioned at blood.After blood enters transparent chamber sliding part 3 can be driven to slidably reciprocate, sealing dress
Put 3-1 and can guarantee that blood does not leak outside, the response ratio that vibrating membrane 3-2 is beaten to pulse is rapider, can be in return spring 3-3 cooperation
Under neatly slidably reciprocated in transparent chamber room, to help medical worker to be judged.The sliding part is not only limited only to
The form provided in the present embodiment, piston, vibrating reed etc. can also be used.As shown in figure 4, if puncture needle 1 punctures blood vessel
6, there will be no pulse beating, the amplitude that sliding part 3 slides will slowly decay until stopping.
In order to prevent bacterium or water from entering in transparent chamber room, the ventilated membrane that blocks water is installed with the gas channel 1-3-1.
In order to preferably observe sliding condition of the sliding part in transparent chamber, the periphery wall of the transparent chamber 1-3 is provided with
The scale (not shown) of amplitude is slided for observing sliding part 3.If puncture needle insertion is vein, because vein pressure compares
Small, then the amplitude that sliding part 3 slides, also can be by scale significantly even if running into the bigger patient of vein pressure with regard to smaller
Made a distinction with artery.
In order that blood does not solidify, anti-coagulants, the end set for puncturing needle tubing 1-1 are filled in the puncture needle tubing 1-1
Have for making the needle cap or diaphragm seal that anti-coagulants do not leak outside.Anti-coagulants can use heparin, hirudin etc..Needle cap can use liver
Plain cap etc..
Backpulsing arterial puncture needle provided by the invention, when puncture needle 1 inserts blood vessel 5, blood is just along puncture needle tubing
1-1 enters in transparent chamber 1-3, and sealing device 3-1 can guarantee that blood does not leak outside, the response ratio that vibrating membrane 3-2 is beaten to pulse
It is relatively rapid, can neatly it be slidably reciprocated in transparent chamber room under return spring 3-3 cooperation, can be according to outside transparent chamber 1-3
Scale read sliding part 3 slide amplitude, so as to judge insertion be artery or vein.If puncture needle insertion is quiet
Arteries and veins, because vein pressure is smaller, then the amplitude that sliding part 3 slides is with regard to smaller, even if running into the bigger patient of vein pressure,
It can significantly be made a distinction by scale with artery.The present invention is simple in construction, and dependable performance, manufacturing cost is low, can help medical matters
Personnel, the medical worker especially to lack experience judge whether insertion artery, to improve the success rate punctured, reduce the pain of patient
Hardship, there are wide market prospects.
Simply technical scheme is explained in detail for above-mentioned embodiment, the present invention not only only office
It is limited to above-described embodiment, every any improvement or replacement according to the principle of the invention all should be within protection scope of the present invention.
