Embodiment Construction

[0024] The present invention provides an automatic arterial blood puncture system and method, which will be further described in conjunction with the accompanying drawings and specific embodiments below.

[0025] The structure of the system is as figure 1 As shown, it consists of a B-ultrasound probe, an automatic puncturer, and an oxygen saturation detector; the B-ultrasound probe 1, the automatic puncturer 2, and the oxygen saturation detector 3 are respectively connected to the computer 6; the front end of the automatic puncturer 2 is provided with a puncture needle 4. The tail end of the puncture needle 4 is connected to the special blood gas needle tube 5 , and the clip of the oxygen saturation detector 3 clamps the special blood gas needle tube 5 .

[0026] The puncture method based on the puncture system is carried out in the following steps:

[0027] (1) B-ultrasound probe 1 judges the position of the artery in two ways:

[0028] (101) Pulse-type blood flow sound, th...

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 [0001] The invention relates to an automatic arterial puncture device and a use method thereof, belonging to the field of medical instruments. Background technique [0002] In clinical work, for some patients with dyspnea, anesthesia or surgery, for special examination or treatment, arterial blood needs to be drawn when blood gas analysis is performed; selective angiography or treatment, cardiac catheterization, hemodialysis treatment, etc., also Arterial puncture is required, and successful arterial puncture can quickly detect life corrections such as gas exchange and acid-base balance of the patient, providing an effective plan for guiding rescue and treatment. Successful arterial puncture escorts related treatments, but when some patients have problems such as low blood pressure, puncture is more difficult. At present, arterial puncture is mainly performed clinically by manual operation, and the arterial sound is easy to resonate, resulting in inaccurate ...
