Adult thoracentesis needle simulator

Pleural puncture (pleural effusion puncture):

(Note: The model has been filled with liquid before leaving the factory. In order to maintain the amount of liquid, it still needs to be injected into the model after the puncture draws out the liquid. At the beginning, use pure water first, and then use the blood simulation fluid after familiarization.)

Before operating the training, turn on the power switch of the left thigh root controller, use the remote control, pull out the antenna, and press the chest piercing button. When operating the training in the sitting position, adjust the posture of the simulated patient, sit on the chair in the opposite direction, and place both arms on the chair. On the upper edge of the back, the head lies above the back of the chair. Puncture points can be selected on both sides of the pleural cavity or multiple locations on one side. Puncture training can be performed on the scapular line, posterior axillary line, or mid-axillary line. The scapular line or posterior axillary line is in the 7th to 8th intercostal space, the mid-axillary line is in the 6th to 7th intercostal space, and the anterior axillary line is in the fifth intercostal space. The puncture needle is inserted vertically along the upper edge of the lower ribs. When passing through the pleural parietal layer, a sense of loss will appear and the pleural effusion can be withdrawn. If the needle is inserted correctly, there will be a voice prompt "The puncture site is correct". If the needle is inserted at the lower edge of the upper ribs, the puncture site is wrong, and the intercostal nerves and blood vessels are easily damaged. There are electronic voice prompts that can say "Wrong location, nerves and blood vessels have been damaged". If you puncture the ninth intercostal puncture at the scapular line or the posterior axillary line, the voice prompts "the location is wrong, the second place is easy to penetrate the diaphragm and damage the abdominal organs".

3. Lumbar puncture (subarachnoid puncture in the spinal canal):

(Note: A segment of the lumbar vertebrae spine model is provided. The lumbar 1 and lumbar 2 lumbar vertebrae of the spine are exposed to facilitate the observation of the morphological structure of the vertebrae and the spinous process space. The lumbar 3, lumbar 4 and lumbar 5 vertebrae spinous process spaces, The sacrococcygeal part is the functional part of the spinal injection model. It has obvious signs on the body surface, easy to identify and touch, and can be used for operation technique training, including lumbar spinal anesthesia (spinal anesthesia), epidural anesthesia, and sacral anesthesia. Perform operation training in the sitting or side lying position. Before operating the training, turn on the power switch of the left thigh root controller, use the remote control, pull out the antenna, and press the waist piercing button.

⑴. Aseptic operation: Before operation, sterile gloves should be worn, and the puncture site should be routinely disinfected, draped, local anesthesia, and postoperative treatment procedures and training.

⑵. Liquid has been injected from the liquid injection port on the left side of the back of the model before leaving the factory, so that the lumbar puncture liquid storage bag is filled with liquid. Before lumbar puncture, the subarachnoid space in the spinal canal should be filled with colorless fluid to simulate normal cerebrospinal fluid for use.

⑶, according to the intersection of the highest point of the iliac crests on both sides and the posterior midline, level 4

Position the spinous process of the lumbar spine. The lumbar puncture point can be selected at the 3rd and 4th lumbar intervertebral space (the lumbar 3-4 or lumbar 4-5 vertebrae spinous process space), and the voice prompts "the puncture site is correct". The model has a needle penetration depth of about 7 cm (adults’ needle penetration depth is about 4-6 cm). The puncture needle is pierced in the lumbar spinous process space in situ or perpendicular to the lateral part, which has a sense of blockage. Once the ligamentum flavum is penetrated, there will be a sense of loss. (It means that the puncture needle enters the subarachnoid space in the spinal canal). At this time, the needle core can be slowly withdrawn (to prevent the rapid outflow of cerebrospinal fluid and cause brain herniation), and the cerebrospinal fluid can be seen flowing out, which means that the lumbar puncture is successful. If you take the first and second lumbar intervertebral space (the lumbar 1-2 or lumbar 2-3 spinous process space) into the needle, the voice prompts "the location is wrong, the nerves and blood vessels have been damaged".

⑷. When performing lumbar puncture training in the lateral position, the model needs to be adjusted to the lateral position, with the knees bent as much as possible. After the lumbar puncture operation training is completed, adjust the model to a sitting position, use the spanners on both sides of the waist of the model, and push the model toward the back of the model to restore the model to its original position.
