Description

Ultrasonic real-time guiding central vein puncture device

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to an supersound real time guiding central vein piercing depth.

Background

The ultrasonic guided central venous puncture catheterization provides a two-dimensional anatomical image of a central vein, and a central venous catheter is placed under the guidance of a real-time image, so that the central venous puncture catheterization is monitored and guided in real time, and whether the central venous catheter is placed at a correct position is confirmed. At present, femoral vein, internal jugular vein and axillary vein can be guided in real time under ultrasonic monitoring, and are more and more widely used in clinic. A great deal of research shows that compared with the traditional body surface anatomical landmark positioning method, the central vein guided by the ultrasonic has obvious advantages, has the advantages of obviously reducing puncture times, shortening puncture and tube placing time, reducing puncture complications, reducing catheter infection and the like, is particularly suitable for severe medical departments, anesthesia departments and emergency departments, and is particularly suitable for puncturing high-risk patients with abnormal blood coagulation mechanisms.

In the prior art, ultrasonic real-time guidance of a central venipuncture catheterization is divided into two operation technologies, namely an out-of-plane guidance technology and an in-plane guidance technology. The out-of-plane and in-plane techniques are determined by the relationship between the ultrasound guide plane and the puncture plane of the puncture needle, the two planes are coincident to form an in-plane guide, and the two planes have a certain angle and are even perpendicular to form an out-of-plane guide. When the ultrasonic real-time guide central venipuncture catheterization is carried out, the position of the needle point can be seen and the correct catheterization can be confirmed by adopting the in-plane technology, so that the occurrence of complications is further reduced. Currently, it is believed that out-of-plane techniques are commonly employed by beginners because they are easier to operate and take less time. In-plane guidance is however still required when puncturing high-risk blood vessels or high-risk patients, for example, when puncturing the axillary vein, the axillary artery, and the central vein of a patient with liver failure. When the in-plane guidance is ideal, the puncture needle can be completely monitored to puncture the vein, the metal guide wire can be clearly seen to be placed into the central vein, the puncture safety can be obviously improved, and the complications can be reduced. But with in-plane techniques the needle is more likely to move out of plane and even disappear in the ultrasound image. Especially, when the puncture needle is operated by a single person, an operator needs to hold the ultrasonic probe by one hand and puncture by the other hand, and the puncture needle is difficult to obtain in the ultrasonic in the puncture process and is easy to fail to guide. Therefore, an ultrasonic puncture outfit is needed to improve the success rate and reduce the difficulty of ultrasonic guided puncture. The couplant is a medical product consisting of aqueous polymer gel, is a lubricant used between a B ultrasonic probe and a human body examination part, is beneficial to ultrasonic conduction between the probe and the skin or mucosa of the human body, enables a doctor to more clearly examine the condition inside the body, and helps the doctor to successfully complete examination. Most of the existing puncture outfits are made of metal and are disinfected for many times, but the puncture outfits have several problems in the application of blood vessel puncture. 1. The use is complicated each time of disinfection; 2. the puncture trajectory is too long, the blood vessel puncture needle is 6.35cm, and the blood vessel is about 4cm away from the skin, so the puncture needle cannot be used; 3. the front surface is not provided with a couplant bag, the storage of the couplant cannot be used, the couplant is required to be filled in the disposable sterile glove for external use, and the use is inconvenient; 4. the probe clip is not firmly fixed and is easy to shift when in use. Therefore, the development of a convenient and practical ultrasonic real-time guided venipuncture device is one of the tasks which are urgently needed to be completed in the field.
