Abstract
The utility model discloses a disposable brachial plexus anesthesia puncture needle, pertaining to the field of medical apparatus. The utility model is structurally composed of a puncture needle core, an indwell pipe shroud and an external connection hose; the puncture needle core is axially nested inside the indwell pipe shroud; a medicine feed hole is arranged at the position near the handing end of the puncture needle core; a medicine feed cavity is arranged at the position corresponding to the medicine feed hole of the handing end of the indwell pipe shroud; the end of the external connection hose is communicated with the medicine feed cavity. Compared with the prior art, the utility model can be widely used in various kinds of upper limb operations with the advantages of convenient using and ideal anesthesia effect.
Description
Technical field
This utility model relates to medical instruments field, and especially a kind of upper extremity operation is with disposable brachial plexus anesthesial puncture needle.
Background technology
Upper extremity operation, operation is replanted in particularly upper limb severed limb (finger), needs tens hours mostly.Present most widely used Therapeutic Method is the single brachial plexus nerve block.As using lignocaine, only about 2 hours of duration of anaesthesia uses the bupivacaine persistent period also with regard to 6 hours, therefore needs to append once more or repeatedly brachial plexus nerve block in the operation during retardance.This not only influences operation technique, and has increased the mortality of anesthesia and the appearance of complication greatly.In the prior art, the somebody utilizes the venous cannula pin to carry out continuous brachial plexus anesthesial.Because the sleeve pipe needle handle is connected with flexible pipe and Y type injection joint, should not directly puncture.When particularly puncturing through the axil road, because can not observe backshank beating with tremulous pulse, so must survey puncture direction, the degree of depth, different sense, arteriopalmus with the intramuscular injection pin earlier, according to circumstances use trocar puncturing again, increase puncture time, punctured blood vessel during simultaneously as detection, formed hematoma, just be difficult to the reuse trocar puncturing, increased the mortality of anesthesia and patient's misery.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of disposable brachial plexus anesthesial puncture needle at above-mentioned deficiency of the prior art, and that this puncture needle has is easy to use, can reach characteristics such as desirable anaesthetic effect.
The technical scheme that its technical problem that solves this utility model adopts is: disposable brachial plexus anesthesial puncture needle, constitute by puncture nook closing member, indwelling casing tube and external hose, the puncture needle mandrel is in being socketed in indwelling casing tube, the puncture nook closing member has medicine feeding hole near the position of handheld terminal, the position of the corresponding medicine feeding hole of indwelling casing tube handheld terminal is provided with drug-intake cavity, and an end of external hose is connected with drug-intake cavity.
The sidewall of indwelling casing tube is provided with scale marker.
Have several drug side openings on the free-ended sidewall of indwelling casing tube.
One end of external hose is connected with drug-intake cavity by telescopic joint head, and the other end is fixed with the syringe union joint.
Disposable brachial plexus anesthesial puncture needle of the present utility model is compared with prior art, has following outstanding beneficial effect:
(1) characteristics of replanting operation at upper limb severed limb (finger) design, easy to use, easy operating, and disposable direct puncture had both reduced puncture time, alleviated the patient suffering, can increase the anesthesia success rate effectively again;
(2) prolong anesthesia duration, the doctor can adjust anaesthetic kind, dosage, concentration as required, has the motility of medication by stages and selection medication;
(3) the free-ended drug side opening of indwelling casing tube helps the anaesthetic diffusion, improves anaesthetic effect;
(4) scale marker on the indwelling casing tube helps grasping the indwelling degree of depth;
(5) one-object-many-purposes except that being used for the surgery anesthesia process, also can be used for the postoperative analgesia.
Description of drawings
Accompanying drawing 1 is the structural representation of the disposable brachial plexus anesthesial puncture needle of this utility model.
The specific embodiment
Explain below with reference to Figure of description disposable brachial plexus anesthesial puncture needle of the present utility model being done.
Disposable brachial plexus anesthesial puncture needle of the present utility model is made of puncture nook closing member 1, indwelling casing tube 2 and external hose 3.
Puncture nook closing member 1 handheld terminal is fixed with handle 4, and puncture nook closing member 1 has medicine feeding hole 5 near the position of handle 4.
The handheld terminal of indwelling casing tube 2 is fixed with handle 6, and drug-intake cavity 7 is arranged in the handle 6.When puncture nook closing member 1 was socketed in the indwelling casing tube 2, medicine feeding hole 5 was positioned at drug-intake cavity 7.Be carved with scale marker 8 on the sidewall of indwelling casing tube 2, free end has three drug side openings 9.
Puncture nook closing member 1 and indwelling casing tube 2 connect together and directly puncture during puncture, after puncturing successfully, connect external hose 3 and syringe, at first inject local anaesthetics 20～30ml, at this moment in flesh inter-drain or axillary sheath, form a liquid lacuna, again indwelling casing tube 2 is inserted 10～20mm according to scale marker, withdraw from puncture nook closing member 1 simultaneously, fixedly indwelling casing tube 2, and external hose 3 connects syringe or analgesia pump, carries out injection or analgesia.
Disposable its processing and fabricating of brachial plexus anesthesial puncture needle of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
