Abstract
The utility model relates to an automatic resistance eliminator for the puncture of hard-membrane exocoele, belonging to the field of the medical anesthesia. The utility model comprises an injection syringe, a piston, a pull rod, a spring, a cylinder cap and a handle. The automatic resistance eliminator for the puncture of hard-membrane exocoele is a judging positioner used when injecting the narcotics into the hard-membrane exocoele. Because the spring instead of the hand is used to press the injection syringe, both hands can control the strength and direction of a puncture needle, and the safe coefficient is increased. Because the utility model can eliminate the resistance automatically when the tip of the injection syringe is pushed into the hard-membrane exocoele without being influenced by the principle of the negative pressure of the hard-membrane exocoele, the positioning accuracy is enhanced. The utility model is easy to operate in clinic and safe in use; the utility model can realize autoclaving sterilization.
Description
The invention belongs to medical anesthesia field, is the judgement localizer when epidural space injects anaesthetic.
The clinical manipulation method of present this area:
One, pressurization
(1) resistance disappearance device: be a kind of the most frequently used method.During puncture, needle point is met the ligamenta flava resistance, promptly pulls out the pin heart, has the syringe of 5 ml physiological salines to be connected to syringe needle suction and with hands pressurization, inserting needle simultaneously.Disappear as unexpected resistance, normal saline can be depressed non-resistance and go into epidural space in adding of hands.The deficiency that resistance disappearance method exists at present is dynamics and the direction when needing a hand control inserting needle, and pressure injector does not have the pressure resistance of hands and can not die away when needle point enters epidural space on the other hand.So both hands can not be controlled the dynamics and the direction of pin, and are difficult in the operation, inconvenience is grasped, and easily causes puncture undue force Spinal Cord to begining to learn the narcot officer.
(2) air bag method or water-filled balloon method: these two kinds of operational approach are that needle point is connected to syringe needle with air bag or water pocket when proceeding to ligamenta flava.In air bag or water pocket, inject air or normal saline with syringe then, air bag or water pocket is full, air bag or water pocket atrophy when needle point enters epidural space.At present the deficiency that exists is that rubber is aging easily, and service life is short, with after can not autoclaving sterilization, need when soaking concentration does not reach the disinfectant purpose, easily to cause the epidural space infection with 75% alcohol-pickled.Can not directly use in the operation, injection air in air bag or water pocket or normal saline that must be indirect be full with it.Wash ethanol in air bag or the water pocket repeatedly with normal saline before using.With after will be in air bag or the water pocket inject alcohol-pickled sterilization.Inconvenience in the use, water pocket or air bag can only be surveyed resistance and disappear, and can not pumpback have or do not have the backflow of cerebrospinal fluid, once can not finish two steps.
Two, negative pressure method
(1) sessile drop method: needle point is met the ligamenta flava resistance, transfers to the pin heart, drips in syringe needle, forms water droplet, when needle point enters epidural space, because of negative pressure sucks water droplet.
(2) WG method: transfer to the pin heart when needle point is met the ligamenta flava resistance, WG is connected to syringe needle, needle point enters epidural space, can absorb water, and fluid pressure just demonstrates negative pressure.At present the deficiency that exists is that negative pressure differs at waist and establishes a capital appearance, so use clinically limitation is arranged.
Task of the present invention is to remedy above-mentioned deficiency, special propose for cavum epidural puncture from the dynamic resistance device that disappears.
Invention structure (see figure 1):
Cavum epidural puncture is to be made of syringe cylinder (1) piston (2) pull bar (3) cover (4) spring (5) handle (6) from dynamic resistance disappearance device.The piston and the pull bar that are connected as a single entity are loaded in the syringe cylinder, and spring housing is on pull bar, and pull bar passes through from the hole, garden at cover center, then cover is screwed in the syringe cylinder afterbody, and the afterbody of pull bar is connected with handle.Syringe cylinder (1) is to have the screw thread (see figure 2) by the normal injection syringe at its tail; Piston (2) is the garden cylindricality and pull bar is connected as a single entity, and the pull bar afterbody has screw thread, the internal diameter break-in (see figure 3) mutually of the diameter of piston and syringe cylinder; Pull bar (3) afterbody has screw thread and is connected with handle; Spring (4) is enclosed within on the pull bar, is loaded between piston and the cover; Handle (5) has the female thread (see figure 4) that is connected with the pull bar afterbody; Cover has screw thread in (6), and there is the hole, garden at the center, and pull bar passes through in the middle of the hole, garden, the cover (see figure 5) that is connected with the syringe afterbody.
Using method: the puncture hour hands proceed to ligamenta flava and transfer to the pin heart, directly be connected to the puncture backshank with what suction had a normal saline from dynamic resistance disappearance device, the dynamics of two hand control inserting needles and direction are injected epidural space from dynamic resistance disappearance device with normal saline automatically when needle point enters epidural space, stop inserting needle this moment, pull back piston then if no cerebrospinal fluid refluxes, take down from dynamic resistance disappearance device, insert epidural catheter, after the injection anesthesia test amount, have no adverse reaction through observation, can inject anesthetics.Stop administration if there is cerebrospinal fluid to reflux, reelect the anesthesia scheme.
Epidural space has replaced power with the hands pressure injector from dynamic resistance disappearance device with the dynamics of spring, so the dynamics and the direction of both hands may command puncture needle have increased safety coefficient.The dynamics of spring can disappear resistance automatically when needle point enters epidural space, be not subjected to the influence of epidural space principle of negative pressure, improved locating accuracy, what can directly suction be had normal saline is connected to syringe needle from dynamic resistance disappearance device, once can finish resistance disappearance and pumpback and have or do not have two steps that cerebrospinal fluid refluxes, easy and simple to handle, but autoclaving sterilization during use is safe and reliable.
