Background
One of the important components for promoting the perioperative quick rehabilitation of patients is effective pain treatment, advocates local or regional nerve block anesthesia analgesia, enables the sensory nerve fiber endings around the wound to be blocked by infiltrating local anesthetic into tissue gaps, fascia gaps, ligament gaps and the like to achieve the regional analgesia effect, the half-life period of the existing long-acting local anesthetic applied to the local or regional nerve block anesthesia analgesia is 8-12 hours, the postoperative wound of the patient lasts for 3-10 days, so the disposable local or regional nerve block anesthesia analgesia cannot well meet the long-time wound continuous analgesia requirement of the patient, when the local anesthesia analgesia is insufficient, opioid analgesic drugs with vein general effects can be applied for substitution and supplement, and when a large dose of opioid analgesic drugs are applied for a long time, nausea and vomiting can be accompanied, Under the background of side effects such as skin itch, respiratory depression, lethargy, constipation, anorexia, dizziness, etc., how to effectively achieve long-term local and regional nerve block anesthesia and analgesia becomes an important clinical proposition!
For continuous subcutaneous analgesia treatment, a trocar (with the length of about 5 cm) can be left for realizing, but for regional nerve block analgesia after the operation of a larger surgical incision, particularly for the analgesia of fascia gaps, ligament gaps or other tissue gaps, a longer indwelling catheter for continuously infiltrating, anesthetizing and easing pain is needed to be placed in the fascia gaps, the ligament gaps or other tissue gaps, local anesthetic is continuously infused or intermittently injected through the catheter, the regional nerve block for a longer time is realized, and the aims of easing pain in an effective region, reducing the pain of a patient and accelerating the recovery of the patient are further fulfilled. The catheter outer diameter must not be too thick to affect tissue healing or cause patient discomfort, requiring multiple side holes to facilitate tissue infiltration in the corresponding area.
Meanwhile, the catheter also has the function of a drainage tube of a small surgical incision, and because the catheter is thin, the influence on tissue healing can be reduced as much as possible when the catheter is used as a drainage tube, and a residual scar after wound healing is smaller after the drainage tube is pulled out.
Disclosure of Invention
To the above problem, the utility model provides a keep somewhere pipe that is used for tissue clearance, manadesma clearance, ligament clearance to infiltrate anesthesia analgesia in succession possesses thereby to keep somewhere the injection narcotic drug for a long time and reach the purpose that the regional retardation is analgesia, and this pipe still possesses the little notched drainage tube function of surgery simultaneously, can be used for little notched surgery postoperative drainage such as thyroid gland operation.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a pair of catheter is kept somewhere in anesthesia analgesia of infiltrating in succession, including the hose, the one end of hose is installed elasticity piston injection joint, and another injection joint of side fixedly connected with that elasticity piston injection connects can external heparin cap, all can be to the other end injection medicine of hose through these two injection joints, evenly is provided with a plurality of through-holes at the front end of hose for the liquid medicine can even outflow distribution in tissue clearance.
Furthermore, a check valve is arranged in the elastic piston injection port.
Further, the through holes are arranged at intervals of 1cm and are distributed at 90 degrees, 180 degrees, 270 degrees or 360 degrees with the axial direction of the hose respectively.
Furthermore, the length of the hose is 15-30cm, so that the anesthesia and analgesia requirements of long wounds can be met. Preferably, the hose is 20 cm long, and through holes are uniformly distributed in the range of 0-15 cm at the front end.
Furthermore, the outer surface of the elastic piston injection joint is provided with an external thread which is matched with the internal thread of a standard transfusion pipe joint or an injector joint.
Further, the outer diameter of the hose is 2-5 mm.
Furthermore, the rear end of the hose is provided with an elastic clamp.
The utility model discloses owing to take above technical scheme, it has following advantage:
(1) the length of the catheter is 20 cm, the front end of the catheter is 15 cm and is provided with a through hole, and redundant parts can be cut off according to the use requirement. Can meet the requirements of continuous infiltration anesthesia analgesia or drainage in tissue gaps, fascial gaps and ligament gaps of longer incisions or small incisions.
(2) The injection device is provided with an elastic compression injection joint and a direct injection or drainage joint, can inject anesthetic, and can also drain through the direct injection joint.
(3) The back end of the catheter is provided with an elastic clamp which can selectively block or release the medicine injection and drainage of the catheter.
(4) The side hole is provided with a wider blocking or drainage range.
(5) The external diameter is 2-5 mm, the tissue reaction is smaller, and the residual scar of the tube orifice after being pulled out is smaller.
