Description
Technical field
This utility model relates to the sniffer that a kind of band is detected deictic function, be specifically a kind of reliable, can accurately detect and indicate and judge that puncture needle arrives the cavum epidural puncture sniffer of epidural space.
Background technology
The medical worker is in the cavum epidural puncture operation, determine that whether puncture needle has arrived epidural space is very crucial problem, have only accurate localised puncture pin to arrive epidural space and just can put the pipe administration, if cause easily that in the errors present administration anesthesia failure even operative failure cause death etc.At present, the doctor judges by experience and feel whether puncture needle enters epidural space mostly, the main injection with low resistance of using is confirmed, injection with low resistance refers in particular to the syringe of push rod resistance less than 0.5N, with conventional syringe essential distinction is arranged, in medical practice, rely on epidural space lower negative pressure characteristics, be used to judge the cavum epidural puncture position.But injection with low resistance is not directly perceived in use entirely with doctor's feel.When syringe needle punctures that into subcutaneous tissue reaches fine and close ligament tissue, syringe needle is plugged, pressure is bigger, pressure discharges when puncturing into spinal epidural cavity, and the doctor relies on sensation preliminary judgement puncture needle to enter epidural space at this moment, but can't full confirmation, need the pull injector push-rod, as push rod push-pull effort no change explanation correct position, prove that then puncture needle has entered subarachnoid space if there is cerebrospinal fluid to extract out, need puncture again.But this operation is higher to doctor's specification requirement, and randomness is strong, can't guarantee that each puncture position is all accurate, and the method efficient is lower, easily causes anesthesia failure or post-operative complication etc.
At present, there is the technical staff to propose to place water droplet at the ordinary syringe tail end at the problems referred to above, pressure reduces after puncture needle enters spinal dura mater, and water droplet can slightly rock under the situation that ambient pressure changes, and the doctor borrows rocking of water droplet of observation further to determine the puncture needle position.But this kind method is inconvenient to observe, and water droplet rocks under the faint situation and do not observe probably.
At the problems referred to above, those skilled in the art propose a kind of syringe with deictic function, but this syringe is an ordinary syringe, relying on pressure to change when using judges the influence of indicating device, the doctor sees when indicating device changes, and also needs the indication syringe unloaded to change injection with low resistance and reaffirm that operating procedure is complicated, if control is bad, the puncture needle position changes probably and causes puncture failure when changing syringe.
In sum, at present for indicating the apparatus of puncture position to have very big demand in the cavum epidural puncture operation accurately and reliably.
The utility model content
In order to improve and remedy the defective of prior art, the purpose of this utility model is to provide reliably cavum epidural puncture sniffer accurately of a kind of result of detection.
To achieve these goals, this utility model adopts following technical scheme:
A kind of cavum epidural puncture sniffer, it comprises syringe body, push rod and anesthesia spinal needle, wherein, the resistance between syringe body and the push rod is less than 0.5N; Also comprise an indicating device, this indicating device is arranged on this syringe body or on the base of anesthesia spinal needle, and the two communicates with this; This indicating device is provided with elastomer, and elastomer is fixed in the indicating device distal portion; Be equipped with the blocking parts of mutual coupling on push rod and the syringe body.Indicating device is arranged at the anterior sidewall of syringe body, is structure as a whole with syringe body.
Another kind of cavum epidural puncture sniffer, it comprises syringe body, push rod and anesthesia spinal needle, wherein, the resistance between syringe and the push rod is less than 0.5N; Also comprise an indicating device, this indicating device is arranged on the base of anesthesia spinal needle, and communicates with it; This indicating device is provided with elastomer, and elastomer is fixed in the indicating device distal portion; Be equipped with the blocking parts of mutual coupling on push rod and the syringe body.The base of above-mentioned indicating device and anesthesia spinal needle is structure as a whole.
Another cavum epidural puncture sniffer, it comprises syringe body, push rod and anesthesia spinal needle, wherein, the resistance between syringe and the push rod is less than 0.5N; Also comprise an intermediate, indicating device is located on this intermediate and with this intermediate and is communicated; This indicating device is provided with elastomer, and elastomer is fixed in the indicating device distal portion; Be equipped with the blocking parts of mutual coupling on push rod and the syringe body; Described indicating device and intermediate are structure as a whole.
In above-mentioned three kinds of indication syringes, the blocking parts of coupling are location snap ring and draw-in groove mutually; Described locator card ring set is located at the syringe body rear portion; Described draw-in groove is arranged on the push rod.Mutually the blocking parts of coupling can also be fixing snap ring, this fixedly snap ring be arranged at the syringe body afterbody and be sheathed on the push rod, when this kind blocking parts are particularly useful for syringe body and push rod and are glass material.Elastomer can produce deformation with atmospheric pressure, as band indicating device of spring or elasticity vesicle etc.Described syringe body leading section is direct insertion structure or screws structure that direct insertion structure is 6: 100 with the tapering of screwing structure.
Advantage of the present utility model and benefit:
This utility model indicating device and syringe body or puncture needle base or intermediate communicate, good airproof performance, and elastomer changes with the variation of atmospheric pressure, changes obviously, is easy to observe.Because this utility model adopts injection with low resistance, the doctor in use repeatedly in the operating process of push-and-pull push rod resistance little, easy to use, the use of injection with low resistance makes the doctor can be after the indicating device indication, further checking puncture result.The holder design is the localization handspike position accurately, and push rod is not replied, and keeps the injection with low resistance internal pressure, makes indicating device work.This utility model is with indicating device and injection with low resistance combination, and new method and traditional method merge to be used, and kills two birds with one stone, and has save the unnecessary trouble of changing syringe, has saved the anesthesia surgery time.The design of the snap ring of the draw-in groove of push rod and indicator body can accurate in locating push rod position, and push rod is not replied in the use, keep-ups pressure.This utility model is simple in structure, and is easy to operate, and the elastomer of indicating device is indicated accurately and reliably the puncture success rate height to pressure variation sensing sensitivity.
