Abstract
The invention discloses a deep-vein piercing needle-changing appliance, which is characterized by the following: the fine needle tunnel and thick needle tunnel connect together with certain separated angle, which intersects to one point from itself centralizing line; the distance from thin needle tunnel tail end and thick tunnel tail end open equals the distance from fine needle and needle end of thick needle.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of deep vein puncture needle changer tool.
Background technology
Deep vein puncture is widely used in clinical each sections such as Anesthesia Department of hospital, oncology, ICU (intensive care unit(ICU)), heart Medicine and Surgery, is one of routine techniques that the patient is monitored and treats.
Before the present invention, thick dark intravenous needle (being commonly called as bodkin) may be accidentally injured patient's large artery trunks, pleura or peripheral nervous when puncturing, cause hemopneumothorax, huge hematoma or serious nerve injury, and can cause the generation of consequence severe complications, even cause death.For fear of this situation, usually use tiny fine needle to detect clinically earlier, to judge dark venous position and direction, treat that fine needle enters and use bodkin behind the dark vein again instead and puncture by the direction that fine needle guides, even also extremely slight because of accidentally injuring patient's large artery trunks, pleura or peripheral nervous consequence in the fine needle probe procedure, thus avoid bodkin blindly detect the severe complication that may cause.But, this operational approach exists the operator can only judge direction according to visual method and experience, cause thus often occurring that fine needle enters dark vein and bodkin still can not enter dark venous situation, making fine needle detect dark vein is that bodkin enters the purpose that dark vein guides smoothly and can't reach, and then can occur bodkin may be accidentally injured patient artery, pleura or peripheral nervous etc. when puncturing phenomenon equally.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, the needle changing device of design, a kind of deep vein puncture external fixation of development.
Technical scheme of the present invention is:
Needle changing device for deep vein puncture, its major technique is characterised in that fine needle tunnel, bodkin tunnel are fixed together, certain angle is arranged between the two, its separately centrage intersect at a point, equate with the needle point of standard component fine needle, bodkin distance respectively from the distance of this nearly empennage end opening, the nearly empennage end opening in bodkin tunnel to the syringe empennage to the fine needle tunnel.
Advantage of the present invention and effect are still to utilize fine needle to detect the dark venous of patient position, utilize the needle changing device of external fixation of the present invention then, promptly utilize fine needle tunnel and bodkin tunnel to be fixed together, and form certain angle between the two, make fine needle, bodkin is separately fixed at the fine needle tunnel, in the bodkin tunnel, fine needle needle point and bodkin needle point intersect at a point, and this joining is to the fine needle tunnel, the distance of the opening of the nearly empennage end in bodkin tunnel equals the fine needle needle point respectively, the bodkin needle point is to the distance of syringe empennage, and fine needle, bodkin all is standard components, thereby accurately enter the dark venous locations of patient that the fine needle needle point detects after making the bodkin needle point by needle changer bodkin tunnel restriction direction and distance at an easy rate, and then avoid occurring bodkin and may accidentally injure patient artery, pleura or peripheral nervous cause hemopneumothorax, the generation of huge hematoma or serious consequence severe complications such as nerve injury.
The present invention is simple in structure, ingenious, and effect is very good, produces easily, and is easy to use, reliable, has great clinical meaning.
Description of drawings
Fig. 1---structural representation schematic diagram of the present invention.
Fig. 2---the present invention is result of use sketch map when fine needle, bodkin fixedly.
The specific embodiment
As shown in Figure 1, fine needle tunnel 1, bodkin tunnel 2 are fixed together, form certain included angle between the two, according to the characteristics of deep vein puncture, angle can be not more than 45 degree between the two, desirable usually 10～35 degree, angle is big, then make big, the Heavy Weight of volume, cost is also big, is good so get 15 degree in this example; The centrage in fine needle tunnel 1, bodkin tunnel 2 intersects at a point forward, the distance of the nearly empennage end opening 3 of fine needle from this joining to 1 rear portion, fine needle tunnel equates that with the distance of the needle point of standard component fine needle 5 to fine needle 5 syringe empennages 7 distance of the nearly empennage end opening 4 of bodkin from this to 2 rear portions, bodkin tunnel equates with the distance of the needle point of standard component bodkin 6 to bodkin 6 syringe empennages 8; 1 liang in fine needle tunnel is located open centre point and bodkin tunnel and is located open centre point for 2 liang and be positioned at same plane with the needle point joint, with conveniently use, operation.
As shown in Figure 2, be that fine needle 5, bodkin 6 are put into fine needle tunnel 1, bodkin tunnel 2 respectively, like this, the needle point of the needle point of fine needle 5 and bodkin 6 intersects at the front a bit, and this point just fine needle 5 detect the dark venous of patient position.
During use, after should entering dark vein with fine needle 5 punctures earlier needle changing device of the present invention is installed again, being about to fine needle 5 inserts in the fine needle tunnel 1, and then bodkin 6 inserted in the bodkin tunnel 2, when the syringe empennage 8 of bodkin 6 is run into the nearly empennage end opening 4 of bodkin 6 in the bodkin tunnel 2, the needle point of bodkin 6 just in time intersects at the needle point of fine needle 5, also faces patient's dark vein, thereby just is easy to carry out deep vein puncture.Use operation of the present invention, avoided the operator obviously, avoided to accidentally injure patient artery, pleura or peripheral nervous etc. with inaccurate, inaccuracy phenomenon that method of estimating and experience may cause.
Fine needle tunnel 1, bodkin tunnel 2 can be made into open loop type, make things convenient for the insertion of fine needle 5, bodkin 6, reduce volume and weight of the present invention, reduce cost, but must guarantee to fix to get final product, and the part of open loop disappearance is not more than half usually.Certainly, fine needle tunnel 1, bodkin tunnel 2 also can be active, are divided into two parts, promptly can open, and close after being enclosed within on fine needle 5, the bodkin 6 again, promptly pin with similar structures such as hasp are fixing.In addition, under sealing and open loop situations, fine needle tunnel 1, bodkin tunnel 2 can be made of plastic, one piece injection mo(u)lding, yield rate height like this, the easy standardization of product.Certainly, also available other materials is made, as metal, macromolecular material etc.
The present invention is a kind of needle changing device of external fixation.
The scope that the present invention asks for protection is not limited to the description of the specific embodiment.
