Description
Technical field
The present invention relates to a kind of anesthesia instruments, more particularly to a kind of adjustable anesthesia for Epidural Block
Conduit system.
Background technique
Epidural block is a kind of anesthesia of wide clinical application.In anaesthesia process, in the operation of center approach,
It needs the lidocaine by 1% to do intradermal, subcutaneous, interspinal ligaments successively to infiltrate.The skin of decanting point point of puncture in other words at this time
It will appear a small bulge.In circumstantial evidence in the operation of approach, needle tubing avoids supraspinal ligament, supraspinal ligament and through ligamentum flavum, it
After set pipe operation.It, can will be for continuously infusing after the piercing needle for determining needle tubing enters epidural space when setting pipe operation
Medicinal anesthetic tube gently injects epidural space by needle tubing, after conduit enters 3~5 centimetres of epidural space, needs on one side
Needle is pulled out, on one side fixing anesthetic tube (anesthetic tube is pushed further into human body while in other words and is also taken to avoid anesthetic tube
Out, until needle is exited skin.After syringe needle extraction, adjusting length of the anesthetic tube in epidural space is 3~4 centimetres,
Anesthetic tube tail end connects syringe, is drawn onto no blood, can fix anesthetic tube without cerebrospinal fluid.Such as benefit card can then be injected
The anesthetic of cause completes anesthesia.
There are the following problems in the above process:
1, above-mentioned small bulge pulls out needle tubing in anesthetist on one side, when fixing anesthetic tube on one side, as forced position, is easy quilt
Anesthetist is pressed into and damages the tissue for having become small bulge, the serious recovery time for extending point of puncture.
2, needle tubing is pulled out on one side, since the preferably not opposite patient of anesthetic tube has any disengaging when fixing anesthetic tube on one side
Movement, and successfully extract needle tubing, anesthetic tube is often taken in the operation for extracting needle tubing at this time out of, cause to set tube failure,
Be entire anaesthesia process be most difficult to operation a bit.
Therefore, the adjustable fiber crops of a kind of tissue of protection point of puncture, the operation difficulty for reducing anaesthesia process are needed at present

Specific embodiment
As shown in figs. 1 to 6, referring to Fig. 1,2,3, a kind of adjustable anesthetic tube system of the present invention includes
Needle tubing 100 is used for inserted into the patient；
Anesthetic tube 200 is used to input medicament, configures in the needle tubing 100；
Tube socket 300, is used to fix the needle tubing 100, and outer surface is fixed with support ring 301；
It is adjustable to pull out needle portion 400, between the support ring 301 of tube socket 300 and patient, two horseshoes are made with guide frame
The supporting block of shape separates, so that extracting needle tubing 100 perpendicular to patient, and drives two roller courts by gear and rack teeth mechanism
Anesthetic tube 200 is stirred to patient.
The present invention by above structure firstly, the position of the small bulge of patient can be bypassed by horseshoe-shaped supporting block,
To avoid pushing up the skin histology of bad patient, and the support ring of tube socket 300 is jacked up by horseshoe-shaped supporting block, guide frame
301 jack up needle tubing 100, so as to extract needle tubing 100 successfully without extracting and bring group since needle tubing 100 tilts
It knits and stretches bring secondary damage.Secondly, when needle tubing 100 is directed away from the direction of user and extracts, said gear rack machine
Structure two rollers of drive stir anesthetic tube 200 towards patient and anesthetic tube 200 are avoided conveniently to be extracted by needle tubing 100.
The process of traditional above-mentioned extraction needle tubing 100 are as follows: thumb, the index finger of one hand of anesthetist catch needle tubing 100 or pipe
Seat 300 extracts needle tubing 100 outward and must not have to middle finger, the nameless skin for abutting against patient since resistance is larger, another
Hand inwardly pushes anesthetic tube 200 to be extracted by the way to avoid anesthetic tube 200 by needle tubing 100.At this point, due to the skin of user
Small bulge is played, if the careless slightly tissue damage that will be pushed up small bulge and increase user of anesthetist, if anesthetist is not
User is abutted against with middle finger, the third finger, then is easy to happen and extracts phenomenon too fast or that extraction is excessive, bad control and adjusting.
Therefore, the present invention, which is abutted against user by horseshoe-shaped supporting block and can abut against, is looped around around the small bulge
Skin histology, to avoid abutting against small bulge.And when pulling out needle tubing 100, speed and length can by the mechanism of lever principle
It adjusts.
Preferably, referring to Fig. 1,2,3,4,5, the adjustable needle portion 400 of pulling out is supported including the first supporting block 401, second

Wherein, second supporting block 402 is moved up and down along first guide rail 403, it should be noted that in order to make
Two supporting blocks 402 do not rotate, do not depart from the first guide rail 403, and it is rectangular guide rail, institute that first guide rail 403, which can be section,
Stating the first guide hole 404 can be for square hole engaged therewith, and certain first guide rail 403 can be equipped with swallow-tail form sliding block, and described first
Guide hole 404 is swallow-tail form guide hole, to allow the configuration of the first rack gear 407 in first guide rail 403 far from first guide hole
On 404 side surface, so that the second supporting block 402 be avoided to touch the first rack gear 407.
Wherein, first supporting block 401, the second supporting block 402 are the shape of a hoof, i.e., described first supporting block 401,
Two supporting blocks 402 are U-shaped, thus make the first supporting block 401 around the small bulge of user, and the second supporting block 402 is around pipe
Seat 300, needle tubing 100 support support ring 301 from the bottom to top, realize the effect for pulling out needle tubing 100.
Preferably, described adjustable to pull out needle portion 400 two horseshoe-shaped supporting blocks separation are agitated with lever principle.
Needle tubing 100 is pulled out due to two horseshoe-shaped supporting blocks of the separate mechanism tilting of lever, to realize needle tubing 100
Extraction speed, length is adjustable or even the extraction angle of needle tubing 100 is also adjustable, might as well control, avoid extracting too fast or pull out
It is excessive out and take anesthetic tube 200 out of and extract together.
Preferably, it is described it is adjustable pull out needle portion 400 further include third connecting rod 431, fourth link 432, the 5th connecting rod 421,
Six-bar linkage 422, the first bayonet lock 423, the first slotted hole 424, the first spring 425, the third connecting rod 431 with described first
The side of bracer 401 is fixed, and the side of the fourth link 432 and the second supporting block 402 is fixed, the 5th connecting rod 421 with
The connection of 431 hinge of third connecting rod, the middle part of the six-bar linkage 422 are connect with 421 hinge of the 5th connecting rod, the six-bar linkage
422 one end close to second supporting block 402 is fixed with the first bayonet lock 423, and it is long that the fourth link 432 offers first
Circular hole 424, is equipped with the first bayonet lock 423 being moved along it in first slotted hole 424, one end of first spring 425 with
