Problems solved by technology
However, in order to master ultrasound-guided nerve block proficiently, a clinical anesthetist who has just started to learn needs to watch and complete a certain number of practical operations under the guidance of the instructor. Among them, the nerve block catheterization technique is more complicated
If teaching directly on the patient, it may bring a series of problems, such as causing psychological and physical trauma to the patient, and the students will also increase the failure rate of the operation due to anxiety, resulting in a long clinical training cycle and poor learning effect
Simulation teaching can solve the above problems. The simulation teaching of surgical laparoscopic surgery has become an important teaching mode. However, the current domestic nerve block simulation teaching still stays in molds such as pork and tofu, which can guide ultrasound-guided nerve block. There is no simple and effective model of nerve block catheterization

Embodiment 1
[0046] Embodiment 1, a kind of preparation method of nerve block catheterization model, carries out following steps successively:
[0047] 1), select pork pieces:
[0048] The size of the pork piece is: length × width × thickness (15±1)cm×(12±1)cm×(5±0.5)cm;
[0049] The pork block includes two upper and lower lean meat layers --- lean meat layer I1 and lean meat layer II3, between the lean meat layer I1 and lean meat layer II3 is the fascia layer 2, the lean meat layer I1 is located at the top of the entire pork block, and the lean meat layer The thickness of Ⅰ is 2cm.
[0050] There is no special requirement under the lean meat layer II3; for example, there may be a fat layer 4 under the lean meat layer II3, and the thickness of the fat layer 4 is usually ≤3cm.
[0051] 2) Two rubber tubes 5 are prepared, and the length of each rubber tube 5 is 20-25 cm. Wherein the diameter (inner diameter) of a rubber tube 5 is 0.5cm, and the diameter (inner diameter) of another rubber ...

The invention discloses a preparation method of a nerve block catheterization model, including the following steps: (1), choosing a pork piece, wherein the pork piece includes upper and lower lean layers, and there is a fascia layer between the upper and lower lean layers; (2) preparing two rubber hoses longer than the pork piece; (3) putting a barium line in one rubber hose, filling the rubber hose with ultrasonic coupling agent and sealing the ends, and directly filling the other rubber hose with ultrasonic coupling agent and sealing the ends; and (4) placing the two rubber hoses in parallel between the lean layers and the fascia layer to get a nerve block catheterization model, wherein the spacing between the two rubber hoses is less than or equal to 0.5cm. The nerve block catheterization model can be used to track the position of a needle tip through puncture under ultrasonic guidance, and can be used in training of a nerve block catheterization technology under ultrasonic guidance.
Description
technical field [0001] The invention relates to a preparation method of a nerve block catheterization model. Background technique [0002] With the development of medicine and the advent of ultrasound visualization, regional nerve blocks have become an increasingly important method of anesthesia. However, in order to be proficient in ultrasound-guided nerve block, a clinical anesthetist who has just started learning needs to watch and complete a certain number of practical operations under the guidance of the instructor. Among them, the technique of nerve block catheterization is more complicated. If teaching directly on the patient, it may bring a series of problems, such as causing psychological and physical trauma to the patient, and the students will also increase the failure rate of the operation due to anxiety, resulting in a long clinical training cycle and poor learning effect . Simulation teaching can solve the above problems. The simulation teaching of surgical l...
