Description
Technical field
The present invention relates to medical field, particularly a kind of arteriopalmus locating development sheet for arterypuncture.
Background technology
Clinical has wound vascular puncture (tremulous pulse, Deep venou), is mostly to carry out tremulous pulse or accompanying vein puncture by the touch specific arteriopalmus point in body surface specific region and traveling.Indicate in the objective indicator of body surface owing to there is no puncture vessel, arteriopalmus by room temperature, patient temperature, heart rate, blood pressure and operator's experience, finger tip thoughts and feelings, finger tip self disturbs even multiple uncontrollable factor such as emotion to affect, success rate and puncture very different consuming time, can be found everywhere to the discussion of various method arterypuncture success rate in document.And the B ultrasonic guided puncture that can be used as guiding puncture gold index is domestic due to reason that is expensive, that use mobile inconvenience at present, with regard to medical conditions domestic at present, do not have the advantage of universalness, therefore find an enough cheap visual replacement scheme extremely urgent.
Study carefully the reason of its vascular puncture failure, often cross extensively directly related with the slide displacement of target arterial, the disperse that not easily touches or beat of beating.Therefore, reduce the area experienced and beat as far as possible, reduce puncture scope, find optimum puncturing point to be only the key of puncture.Puncture out of shape closely related then with blood vessel of the success of rearmounted pipe, putting pipe and avoiding lopsided differentiated vascular in advance forward is also the problem needing to take precautions against.
Summary of the invention
The invention provides a kind of arteriopalmus locating development sheet with low cost, easy to use.
For achieving the above object, technical scheme of the present invention is:
A kind of arteriopalmus locating development sheet, comprises display device, it is characterized in that:
