Abstract
The utility model relates to a medical device and in particular relates to a safe dual-tube epidural anesthesia catheter which comprises an anesthesia catheter, wherein a flexible tube is connected to one end of the anesthesia catheter, an anesthetic delivery tube I and an anesthetic delivery tube II are arranged in the anesthesia catheter and the flexible tube, anesthetic outlets I are formed on the side face of the anesthetic delivery tube I, and anesthetic outlets II are formed on the side face of the anesthetic delivery tube II. The dual-tube epidural anesthesia catheter is implanted in vivo easily and safely, and has large anesthesia coverage; and a quick effect is produced.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of anesthetic tube from anaesthetic to epidural that carry.
Background technology
Epidural block is a kind of anesthesia of wide clinical application, has advantages such as being easy to be convenient to after management, the operation the outer analgesia of die in simple to operate, with low cost, the operation.But complication or anesthesia were lost efficacy and also often to be seen due to the epidural catheter, common put that pipe difficulty, tissue injury, indwelling position are not good, difficulty in decannulation etc., were main with blood vessel and nerve injury again in the tissue injury.
Conduit is inserted resistance when big, and conduit does not get into epidural space or part gets into, if keep somewhere by force then cause spinal dura mater to be worn out probably this moment, and blood vessel injury, nerve injury causes guiding-tube bend, wrecks etc.; Extradural hemorrhage can cause hard outer retardance complete or form the hematoma compression nerve and cause neural control area sensation moving obstacle, penetrates blood vessel or be strayed into blood vessel to cause local anesthesia to be poisoned retardance completion etc.Epidural catheter chamber blood back and clottage conduit; Conduit accidental injury blood vessel caused hemorrhage or obstruction when the die exocoel was put pipe, was the common factor of epidural anesthesia failure, and hard film external anesthetic puncture is put in the pipe process; Often really up to the mark because of the conduit material, cause in the hemorrhage or intravascular epidural catheter placement of epidural space; Puncture needle side opening and dura mater angle are bigger during the puncture of waist section, also are prone to cause put manage difficulty.
In operation, existing anesthetic tube is single lumen catheter not in addition, can only anaesthetize limited plane, and anaesthetic effect is limited, and anesthesia medicinal liquid diffusion is inhomogeneous etc., and when large-scale operation, need do 2 punctures, puts and two-tubely could satisfy requirements of operation.
The utility model content
The technical problem that this utility model will solve provides and a kind ofly is easy to insert, safety, anesthesia area are big, the double hose peridural anesthesia conduit of instant effect.
The content of this utility model is to comprise anesthetic tube; Said anesthetic tube one end is connected has flexible pipe; Be provided with defeated anesthesia pencil I and defeated anesthesia pencil II in said anesthetic tube and the flexible pipe; Said defeated anesthesia pencil I side is provided with out anesthetics hole I, and said defeated anesthesia pencil II side is provided with out anesthetics hole II.
Preferably, the hardness of said flexible pipe is less than the anesthesia pencil.It is said that to go out anesthetics hole I and the position that goes out anesthetics hole II be unequal apart from the distance of hose.Saidly go out anesthetics hole I and be respectively 2 with the number that goes out anesthetics hole II.Said anesthetic tube is provided with graduation mark.Said anesthetic tube is provided with X-ray development line.
The beneficial effect of this utility model is, this utility model front end adopts flexible pipe, and the hardness of hardness ratio anesthetic tube is little, at the tissue blood vessel of inserting Shi Buhui damage human body; The sidepiece of flexible pipe has out the anesthetics hole, and injection speed is improved.This utility model adopts two-tube, can reduce the epidural number of operations, shortens anesthesia duration, reduces less patient suffering.
Being arranged on of this utility model goes out anesthetics hole I and the position that goes out anesthetics hole II and anesthetic tube transverse plane not on a horizontal plane on defeated anesthesia pencil I and the defeated anesthesia pencil II, can carry out large-area anesthesia corresponding to different at different position and different, raises the efficiency.
This utility model anesthetic tube is provided with graduation mark, can clearly show the degree of depth that anesthetic tube inserts, the carrying out of convenient operation.Anesthetic tube is provided with X-ray development line, can under the situation that anesthetic tube wrecks, clearly demonstrate the position of wrecking, the convenient taking-up.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
In the drawings, 1 defeated anesthesia pencil I, 2 defeated anesthesia pencil II, 3 go out anesthetics hole I, 4 flexible pipes, 5 anesthetic tubes, 6 graduation marks, 7 and go out anesthetics hole II.
The specific embodiment
Shown in accompanying drawing; This utility model comprises anesthetic tube 5; Said anesthetic tube 5 one ends are connected has flexible pipe 4; Be provided with defeated anesthesia pencil I1 and the defeated pencil II2 that anaesthetizes in said anesthetic tube 5 and the flexible pipe 4, said defeated anesthesia pencil I1 side is provided with out anesthetics hole I3, and said defeated anesthesia pencil II2 side is provided with out anesthetics hole II7.
The hardness of said flexible pipe 4 is less than anesthesia pencil 5.It is said that to go out anesthetics hole I3 and the position that goes out anesthetics hole II7 be unequal apart from the distance of flexible pipe 4 ends.Saidly go out anesthetics hole I3 and be respectively 2 with the number that goes out anesthetics hole II7.Said anesthetic tube 5 is provided with graduation mark 6.Said anesthetic tube 5 is provided with X-ray development line.
This utility model front end adopts flexible pipe 4, and the hardness of hardness ratio anesthetic tube 5 is little, at the tissue blood vessel of inserting Shi Buhui damage human body; The sidepiece of flexible pipe 4 has out the anesthetics hole, and injection speed is improved.This utility model adopts two-tube, can reduce the epidural number of operations, shortens anesthesia duration, reduces less patient suffering.
Being arranged on of this utility model goes out anesthetics hole I3 and the position that goes out anesthetics hole II7 and anesthetic tube 5 transverse planes not on a horizontal plane on defeated anesthesia pencil I1 and the defeated anesthesia pencil II2; Can carry out large-area anesthesia corresponding to different at different position and different, raise the efficiency.
This utility model anesthetic tube 5 is provided with graduation mark 6, can clearly show the degree of depth that anesthetic tube 5 inserts, the carrying out of convenient operation.Anesthetic tube 5 is provided with X-ray development line, can under the situation that anesthetic tube 5 wrecks, clearly demonstrate the position of wrecking, the convenient taking-up.
