Abstract
The utility model provides a continuous lumbar anesthesia guiding tube, which comprises an epidural guiding tube, a fine needle is installed at the top inside of the epidural guiding tube, the point of the fine needle extends out of the top of the epidural guiding tube, and the internal chamber of the fine needle is communicated with the epidural guiding tube. the models of the fine needle are 5 and 6. The length of the fine needle fastened in the epidural guiding tube is H, the length that the fine needle extends out of the epidural guiding tube is H1, the length H is 1cm to 3.5cm and the length H1 is 0.5cm to 1cm. the utility model can be operated easily when the continuous lumbar anesthesia is performed, avoids the headache after anaesthesia due to too much loss of cerebrospinal fluid, is uneasy to cause the cauda equina ayndrome, reduces the implanted depth of the guiding tube during continuous lumbar anesthesia and can fix the position of the needle point. The utility model has the advantages of simple structure, easy operation, safety, reliability, continuous administration and so on.
Description
Technical field
This utility model relates to medical instruments field, specifically is a kind of continuous spinal anesthesia conduit.
Background technology
Subarachnoid block is called for short continuous spinal anesthesia continuously, is to keep somewhere subarachnoid space conduit and low dose of, gradation administration, the method for carrying out intravertebral anesthesia.The conduit that continuous spinal anesthesia adopts generally has two kinds, and first kind is the large-diameter catheter of 17G or 18G, has a headache after causing lumbar anesthesia easily after the use; Second kind is the microtubular of 28G, uses the back that the horse hair syndrome takes place easily.Because the problem that conduit exists makes the continuous spinal anesthesia technology not apply in clinical anesthesia.
Summary of the invention
The purpose of this utility model provides a kind of continuous spinal anesthesia conduit, it can solve existing technical problem, add fine needle on the epidural catheter top, make conduit need not insert intracavity under the spider web, the excessive cerebrospinal fluid that causes of pinprick loses when having reduced the spinal dura mater puncture, avoided having a headache behind the lumbar anesthesia, the horse hair syndrome can not take place simultaneously, can realize that lumbar anesthesia is adjustable in the anesthesia process, controlled, the heavy and light lumbar anesthesia is also used.Easy to use, simple in structure, easy operating, safe and reliable.
This utility model is achieved through the following technical solutions for achieving the above object: the continuous spinal anesthesia conduit comprises epidural catheter, the inner fine needle of installing in epidural catheter top, and the needle point of fine needle stretches out the epidural catheter top, and the fine needle internal cavity is communicated with epidural catheter.The model of fine needle is No. 5 and No. 6.The length that fine needle is fixed in the epidural catheter is H, and the length that fine needle stretches out epidural catheter is H1, and the length of H is 1cm-3.5cm, and the length of H1 is 0.5cm-1cm.The epidural catheter outer wall is provided with the conduit scale.
Advantage of the present utility model is: processing ease when implementing continuous spinal anesthesia, avoided having a headache after losing the anesthesia that too much causes because of cerebrospinal fluid, and be difficult for causing the horse hair syndrome, the degree of depth that conduit is inserted when having reduced continuous spinal anesthesia, and fixing tip position.Have simple in structure; Easy operating; Safe and reliable; Characteristics such as can offer medicine continuously.
Description of drawings
Accompanying drawing 1 is a main TV structure sketch map of the present utility model.
The specific embodiment
Among the figure, the 1st, epidural catheter, the inner fine needle 3 of installing in epidural catheter 1 top, the needle point of fine needle 3 stretches out epidural catheter 1 top, and fine needle 3 internal cavities 2 are communicated with epidural catheter 1.The model of fine needle 3 is No. 5 and No. 6.The length that fine needle 3 is fixed in the epidural catheter 1 is H, the part that fine needle 3 is fixed in the epidural catheter 1 can play fixed effect in intervertebral space, through development test, the length of H is preferably 1cm-3.5cm, A/C and handled easily when being convenient to lumbar anesthesia.The length that fine needle 3 stretches out epidural catheter 1 is H1, and through development test, the length of H1 is preferably 0.5cm-1cm, can carry out the lumbar anesthesia operation more accurately.Epidural catheter 1 outer wall is provided with conduit scale 4, can observe directly tube insertion depth when continuous spinal anesthesia, judges accurately whether the lumbar anesthesia conduit is in place.
When this utility model uses, with the lancet puncture that matches with this utility model, after puncture needle arrives epidural space and confirms, directly insert the continuous spinal anesthesia conduit, when the fine needle 3 and the needle point of puncture needle were overlapping, to continuous spinal anesthesia conduit thrust a little, fine needle 3 can be inserted in the subarachnoid space, and because the position of fine needle 3 just in time is the center of puncture needle, so the rate of inserting of continuous spinal anesthesia conduit is very high.
Claims (4)
1. the continuous spinal anesthesia conduit comprises epidural catheter (1), it is characterized in that: the inner fine needle (3) of installing in epidural catheter (1) top, and the needle point of fine needle (3) stretches out epidural catheter (1) top, and fine needle (3) internal cavity (2) communicates with epidural catheter (1).
2. continuous spinal anesthesia conduit according to claim 1 is characterized in that: the model of fine needle (3) is No. 5 and No. 6.
3. continuous spinal anesthesia conduit according to claim 1 and 2, it is characterized in that: the length that fine needle (3) is fixed in the epidural catheter (1) is H, the length that fine needle (3) stretches out epidural catheter (1) is H1, and the length of H is 1cm-3.5cm, and the length of H1 is 0.5cm-1cm.
