Technical Field
The utility model relates to the field of medical appliances, in particular to a parasternal intercostal nerve block porous indwelling tube.
Background
Chest open surgery is used as an invasive large-scale operation, is large in wound, and is severely painful after operation due to unavoidable intercostal nerve damage, so that postoperative pulmonary function recovery of a patient is severely limited, and the postoperative pulmonary function recovery is avoided, such as cough and deep breath, and the like, so that postoperative pulmonary tension, pulmonary infection and even complications such as respiratory failure and death of the patient are caused.
At present, a plurality of methods such as intramuscular injection, intravenous injection, percutaneous automatic control pain pump, intercostal nerve freezing, intermittent or continuous intercostal nerve blocking, epidural pain relieving, oral pain relieving medicines and the like are adopted, the intercostal nerve blocking can be used for evaluating and treating chest wall and upper abdomen pain, and the intercostal nerve blocking with local anesthetics can be used for treating chest opening postoperative pain, cancer pain, rib fracture, liver metastasis lesion and postherpetic neuralgia. For the response of patients to different pains, it is common that the injection points of the patients need different anesthesia areas and anesthesia needs, and corresponding measures are needed to improve and adapt to the needs of the patients.
The prior intercostal nerve indwelling needle is provided with a liquid outlet hole in one direction, the liquid outlet hole is positioned at the needle point, the needle point is penetrated into the parietal pleura incision for anesthesia, the inter-costal nerve indwelling needle with the structure has smaller anesthesia scope, the intercostal nerve above the parietal pleura incision and the intercostal nerve below the parietal pleura incision cannot be anesthetized, pain of a patient cannot be effectively reduced, and the intercostal nerves in different directions are anesthetized by penetrating into different directions for multiple times at the moment, so that the anesthesia scope is enlarged, multiple times of wounds are caused to the patient by the multiple-time penetrating mode, and the anesthesia process is complicated.
Accordingly, there is a need to provide a parasternal intercostal nerve block porous indwelling tube that addresses the above-described issues.
Disclosure of Invention
The utility model provides a porous indwelling tube for parasternal intercostal nerve block, which solves the problems.
In order to solve the technical problems, the utility model provides a multi-hole retention tube for parasternal nerve block, which comprises a connecting tube, wherein the bottom end of the connecting tube is provided with a retention needle, the top end of the connecting tube is communicated with a liquid inlet tube, and one side of the connecting tube is communicated with a sampling tube;
the bottom of keeping somewhere the needle is provided with the pinhole, and keep somewhere the surface of needle and be provided with four liquid holes.
Preferably, one end of the liquid inlet pipe is provided with a liquid inlet head.
Preferably, one end of the sampling tube is provided with a connector.
Preferably, the length of the indwelling needle is 12mm.
Preferably, the interval of the four liquid outlet holes is 2.8mm.
Compared with the related art, the parasternal intercostal nerve block porous indwelling tube provided by the utility model has the following beneficial effects:
the utility model provides a multi-hole indwelling tube for blocking the intercostal nerve beside a sternum, which flows out anesthetic through four liquid outlet holes with different distances on an indwelling needle and a needle hole at the bottom, enlarges the anesthetic range of tissues around the indwelling needle, reduces the repeated trauma to a patient in a repeated puncturing mode, has simple anesthetic process, reduces a lot of pains to the patient, and has great progress significance to the patient and a doctor.
