Abstract
The utility model provides a kind of tapered segmental epidural catheter of head end, including conduit and pipe joint, the tube at one end and the pipe joint socket connection；The caliber of the conduit other end is tapered, and if being provided with dry side medicine outlet hole in its end.The utility model is rational in infrastructure, novel in design, and head end is tapered, and anesthetic tube is more soft, inserts epidural space and easily changes direction, intervention damage is reduced, suitable for the special circumstances that implantation site is narrow.Insert that rear anesthetic tube is small to neurothlipsis, and patient is more comfortable, reduce postoperative complications.
Description
Technical field
The utility model belongs to Medical anesthetic fixture technology field, and in particular to a kind of tapered caudal anaesthesia of head end is led
Pipe.
Background technology
Extradural nerve block of the prior art is a kind of anesthesia of wide clinical application, have it is simple to operate,
Cost is cheap, is easily managed in art, postoperative the advantages that being easy to Epidural analgesia, and critical piece used in this anesthesia is
Anesthetic tube, syringe can not be directly connected to because anesthetic tube external diameter is generally less than 1mm, so needing one during infusion medicine
Anesthetic tube connector, connector one end connection anesthetic tube, other end connection delivery device.Traditional anesthetic tube is by transparent
Conduit and pipe joint grafting form.When the anesthetic tube of this structure is inserted compared with Small loss position, anesthetic tube can oppress god
Through sufferer is uncomfortable, and is also easy to produce complication.
The content of the invention
In view of the above the shortcomings that prior art, the purpose of this utility model is to provide a kind of head end tapered Epidural cavity
Anesthetic tube, for solving problems present in prior art.
In order to achieve the above objects and other related objects, the utility model provides a kind of tapered caudal anaesthesia of head end and led
Pipe, including conduit and pipe joint, the tube at one end and the pipe joint socket connection；The caliber of the conduit other end
D is tapered, and if being provided with dry side medicine outlet hole in its end.
Preferably, it is other parts to ends taper at one end 4-10cm of the conduit away from the pipe joint
The 40-80% of caliber.
Preferably, the material at one end 4-10cm of the conduit away from the pipe joint to its end is nylon material
Matter.
Preferably, length direction is provided with the impermeable developing line of X-ray in the duct wall.
Preferably, it is provided with the duct wall some apart from mark line.
Preferably, it is described to be marked apart from mark line since the conduit is away from one end of the pipe joint, after 100mm
Every described in 50mm apart from mark line overstriking mark.
As described above, the tapered segmental epidural catheter of head end of the present utility model, has the advantages that：
The tapered segmental epidural catheter of the head end includes conduit and pipe joint, the tube at one end and the pipe joint
Socket connection；The caliber of the conduit other end is tapered, and if being provided with dry side medicine outlet hole in its end.The utility model knot
Structure is reasonable, novel in design, and head end is tapered, and anesthetic tube is more soft, inserts epidural space and easily changes direction, reduces intervention damage
Wound, suitable for the special circumstances that implantation site is narrow.Insert that rear anesthetic tube is small to neurothlipsis, and patient is more comfortable, reduce art
Infectious-related complication.
Brief description of the drawings
Fig. 1 is shown as the structural representation of the tapered segmental epidural catheter of head end described in the utility model.
In figure：1- pipe joints, 2- conduits, 3- sides medicine outlet hole, 4- is apart from mark line.
Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
Refer to Fig. 1.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only coordinating
Content disclosed in specification, so that those skilled in the art understands and reads, being not limited to the utility model can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influenceing the effect of the utility model can be generated and the purpose that can reach, all should still fall in the utility model institute
The technology contents of announcement are obtained in the range of covering.Meanwhile in this specification it is cited as " on ", " under ", "left", "right",
The term of " centre " and " one " etc., understanding for narration is merely convenient to, and is not used to limit the enforceable scope of the utility model,
Its relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in figure 1, the utility model provides a kind of tapered segmental epidural catheter of head end, including conduit 2 and conduit connect
First 1, described one end of conduit 2 and the socket connection of the pipe joint 1；The caliber D of the other end of conduit 2 is tapered（Due to
The change of its caliber ratio is smaller, is not shown in figure）And if it is provided with dry side medicine outlet hole 3 in its end.
To ends taper it is it at one end 6cm of the conduit 2 away from the pipe joint 1 in another embodiment
The 70% of his part caliber.Experiment proves that ends taper is the 70% of other parts caliber D, it can both ensure that anesthesia was led
The hardness of pipe, the damage to agents area can be reduced again.Further to improve the toughness of conduit, the material of the part can be selected
Use nylon material.Nylon is prior art, and anesthesia described in the utility model can be both prepared using routine techniques from the material
Conduit.
In another embodiment, length direction is provided with the impermeable developing line of X-ray in the tube wall of conduit 2.In the duct wall
Provided with some apart from mark line 4.It is described to be marked apart from mark line 4 since the conduit is away from one end of the pipe joint,
Every described in 5cm apart from the overstriking of mark line 4 mark.Mark for ease of reading, marked at 100mm using two-wire, used at 150mm
Three wire tags, by that analogy.
The utility model is rational in infrastructure, novel in design, and head end is tapered, and anesthetic tube is more soft, and it is easy to insert epidural space
Change direction, intervention damage is reduced, suitable for the special circumstances that implantation site is narrow.Rear anesthetic tube is inserted to neurothlipsis
Small, patient is more comfortable, reduces postoperative complications.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
