Abstract
The utility model relates to a deep vein puncture needle, which is capable of accurately measuring needle puncture depth and preventing formation of air embolism due to air entering deep vein. Scales are formed on the needle body, and a film is arranged in the center of a measuring orifice of a three-way pipe, so as to prevent air entering deep vein during puncture.
Description
Affiliated technical field
This utility model relates to a kind of Y-moldeed depth venipuncture needle, and its needle tubing is provided with scale; The threeway side opening is executed the accurate degree of depth that the patient can observe puncture at any time with diaphragm seal, and can effectively prevent the air embolism complication.Improved the safety of deep vein puncture intubate.
Background technology
At present, known deep vein puncture pin is by tee T and needle tubing and pintail puncture Intubaction device in aggregates.Simple in structure, easy to operate.After the puncture intubate, whole puncture needle can be pulled out, and patient's normal activity is not had influence.But in the piercing process, when causing the acute variation of chest as if patient's cough or because of other reasons, air might enter dark vein from the puncture needle side opening fully, forms air embolism, and patient's life is caused danger.Owing to do not have scale on the puncture needle, execute the patient and can only estimate that puncture needle enters the intravital degree of depth of patient, cause the puncture difficulty, and can cause the infringement of its hetero-organization.
Summary of the invention
Can not accurately measure the degree of depth of inserting needle in order to overcome existing deep vein puncture pin, and may form the deficiency of air embolism, this utility model provides a kind of deep vein puncture pin, this deep vein puncture pin can not only accurately be measured the degree of depth of inserting needle, and can prevent the dark vein of air admission and form air embolism.
The technical scheme that its technical problem that solves this utility model adopts is: thin film is set in the middle of the side opening of tee T, make it in piercing process, stop the dark vein of air admission, after puncture needle enters vein, can insert seal wire from side opening, and make seal wire penetrate thin film, enter dark vein, import in the dark venous conduit by seal wire again.On needle tubing, be provided with scale, avoid blindly crossing dark puncture.Cause its hetero-organization or organ injury.
The beneficial effects of the utility model are, can not only prevent in the piercing process, enter dark vein fully and form air embolism, and can accurately measure the degree of depth of inserting needle, improved the accuracy rate of puncture, shortened the puncture time, reduced other histoorgans of damage in the piercing process and form complication.
Description of drawings:
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the schematic diagram of this utility model deep vein puncture pin.
1. needle bodies, 2. scales, 3. main backshank 4. side backshanks 5. thin film among the figure.
The specific embodiment
In Fig. 1, needle body (1) if can not go out venous blood and surpass the bodily form according to patient according to its degree of depth of scale (2) in the deep vein puncture process in main backshank (3) pumpback, the degree of depth fat or thin and that the site of puncture is estimated should be extracted puncture needle with regard to not continuing inserting needle to subcutaneous and change puncture direction continuation puncture, or puncture needle extracted fully reselect point of puncture and continue puncture, when puncture person from main backshank (3) but when pumpback goes out venous blood left hand fixedly the puncture needle right hand seal wire inserted and broken through thin film (5) from side backshank (4) enter needle body, continue to enter the arrival vein again.
Claims (1)
1. a novel deep vein puncture pin is characterized in that: be provided with scale on needle body, thin film is set in the middle of the side opening of tee T.
