Abstract
The invention relates to an automatic arterial puncture device and a usage method of the automatic arterial puncture device, and belongs to the field of medical instruments. The system is composed of a B-ultrasonic probe, an automatic puncture instrument and an oxygen saturation detector. The B-ultrasonic probe, the oxygen saturation detector and the automatic puncture instrument are connected with a computer. The B-ultrasonic probe is provided with the automatic puncture instrument. The position of an artery is judged through two modes of the B-ultrasonic probe, wherein one mode is that the position corresponding to the maximum value of pulse sound of pulse beating is selected as an artery blood vessel; the other mode is that by pressing through the probe, the blood vessel which is not changed in shape as is shown on a screen is an artery. The computer recognizes and then positions the artery blood vessel, a puncture needle head punctures into the artery blood vessel, blood enters the puncture needle head, arterial blood flows into a needle tube, and the oxygen saturation detector detects whether the blood is arterial blood or not. When the level of the arterial blood in the special blood gas needle tube stops rising, the needle head is pulled off, and a puncture point is pressed in a pressurized mode to complete the whole puncture process. The whole puncture process is high in efficiency and speed, and obvious effects of improving puncture efficiency and relieving the puncture pain of a patient are achieved.
Description
Technical field
The present invention relates to a kind of self-action arterial puncture device and using method, belong to medical instruments field.
Background technology
In clinical position, for part dyspnea, anesthesia or average of operation periods patient, execution special examined or treatment, while doing blood gas analysis, need to extract arterial blood; Selective angiography or treatment, cardiac catheter is inserted, hemodialysis etc., need to carry out arterypuncture equally, successfully carry out arterypuncture and can detect rapidly the life such as patient's gas exchange and acid-base balance and make a comment or criticism, for instructing, rescue and treatment provides effective scheme.Arterypuncture is successfully that associated treatment escorts, but when the problems such as blood pressure is low appear in part patient, venipuncture difficulty is larger.At present, arterypuncture is clinically mainly by manual operation, the easy sympathetic response of tremulous pulse sound, cause artery position judgement inaccurate, puncture subjectivity is larger, be that inserting needle position, needle angle, the degree of depth etc. rely on medical personnel's experience to grasp completely, easily cause puncture to take out arterial blood mistiming and extract venous blood or arteriovenous mixing blood out, incur loss through delay and rescue.For being engaged in not long medical personnel of clinical position time, grasp exactly inserting needle position, angle and degree of depth tool and acquire a certain degree of difficulty, often to, through the success of puncture ability for several times, to patient, bring misery simultaneously.Because tremulous pulse regioselective is inaccurate and the venous blood that punctures causes the disconnected conditions of patients of erroneous judgement by mistake, miss best therapeutic time, and bring serious doctor-patient relationship.
Patent CN 102451041A discloses a kind of Arteriovenous puncture instrument.But this puncture apparatus also fails automatically to identify arteries to realize automatic puncturing.And there is not the arteriovenous automatic discrimination of puncture vessel, can not realize fast automatic puncture.
Summary of the invention
In order to solve the problem of arterypuncture difficulty, improve clinical puncture success rate and alleviate patient suffering, the invention provides a kind of self-action arterial puncture device and using method.
The technical scheme that perforator of the present invention adopts is:
This perforator is comprised of Ultrasonic-B probe, oxygen saturation detector and automatic puncturing instrument; Ultrasonic-B probe, automatic puncturing instrument and oxygen saturation detector are connected with computer respectively; Ultrasonic-B probe carries automatic puncturing instrument, and the front end of automatic puncturing instrument arranges puncture needle, and puncture needle tail end connects special blood air tube pipe, and oxygen saturation detector clip is clamped special blood air tube pipe.
Piercing method based on described perforator, carries out according to the following steps:
(1) by two kinds of modes of Ultrasonic-B probe, judge artery position:
(101) pulsed blood flow sound, selecting the corresponding position of pulsed sound peak of beat pulse is arteries;
(102) by probe, press, on screen, show shape of blood vessel constant for tremulous pulse;
2), according to B ultrasonic imaging, the height of computer automatic measurement & calculation arteries center position skin, sets the numerical value that piercing needle enters, and prevents that piercing needle from penetrating dark;
(3) behind computer identification location, piercing needle puncture enters arteries, and because the large blood of Intraarterial pressure enters rapidly in piercing needle, computer automated imaging, confirms piercing needle intravasation, stops puncture, and maintains static; (3) two kinds of methods of step (2) and step guarantee the accuracy of syringe needle puncture;
(4) arterial blood flows into after puncture needle pipe, and oxygen saturation detector determines whether as arterial blood again by detecting, and the measured value that is clipped in patients fingers and is clipped in the oxygen saturation detector on the needle tubing of special-purpose arterial blood gas differs and is no more than 2%;
(5) in special blood air tube pipe, arterial blood plane tops out, and proves that arterial blood stops flowing into, and computer is confirmed EO, pulls out puncture needle.
(6) tremulous pulse completes after puncture, and the cotton balls of pressing needs Elastic bandage pressurization to press point of puncture outward.
The present invention compared with prior art has following beneficial effect:
(1) can accurately distinguish arteries and vein blood vessel, prevent from phlebotomizing by mistake.
(2) drawback that has solved artificial puncture and operated by rule of thumb; Improve the problem that artificial puncture success rate is low;
(2) solve the process that new registration nurse need practise and accumulate experience with patient;
(3) when drawing blood, accurately judging drawn blood liquid is arterial blood or venous blood.
Accompanying drawing explanation
Fig. 1 is the structural representation of system of the present invention.
Number in the figure:
The super probe of 1-B; 2 automatic puncturing instrument; 3-oxygen saturation detector; 4-puncture needle; 5-special blood air tube pipe; 6-computer.
The specific embodiment
The invention provides a kind of self-action arterial blood lancing system and method, below in conjunction with the drawings and specific embodiments, the present invention will be further described.
The structure of this system as shown in Figure 1, is comprised of Ultrasonic-B probe, automatic puncturing instrument, oxygen saturation detector; Ultrasonic-B probe 1, automatic puncturing instrument 2, oxygen saturation detector 3 are connected with computer 6 respectively; The front end of automatic puncturing instrument 2 arranges puncture needle 4, and the tail end of puncture needle 4 is connected with special blood air tube pipe 5, and the clip of oxygen saturation detector 3 is clamped special blood air tube pipe 5.
Piercing method based on described lancing system, carries out according to the following steps:
(1) Ultrasonic-B probe 1 judges artery position by two kinds of modes:
(101) pulsed blood flow sound, selecting the corresponding position of pulsed sound peak of beat pulse is arteries;
