Description
Technical field
This utility model relates to a kind of armarium, specifically a kind of hard waist combined anesthesia puncture bag of automatic detection epidural space position.
Background technology
Epidural anesthesia, also known as retardation of external cavity of dura mater, epidural space is injected to block the sensory nerve of corresponding sections spinal cord, nervus motorius and sympathetic, parasympathetic centripetal fiber by local anaesthetics, thus block the destructive stimulus of local, expansion peripheral blood vessel, body circulation resistance is declined, alleviates load before and after heart; The epidural space retardance of upper thoracic section also can improve the equilibrium of supply and demand of myocardium oxygen, reduces the incidence rate of malignant arrhythmia.During epidural anesthesia, level of anesthesia has segmental, anesthesia duration is convenient to regulation and control, it is perfect, of flaccid muscles to ease pain, and the impact of patient's body is less favourable to aftertreatment relatively, its advantage is numerous, and therefore epidural anesthesia remains employing one of anesthesia the most widely.
Can epidural anesthesia success often depend on the position correctly locating epidural space, and the method for locating epidural space is varied, and current Anesthetist the most often adopts the change of resistance when determining that the method for epidural space is puncture.When puncture needle enters ligamenta flava, resistance increases, at this moment nook closing member is extracted out, connect the syringe with small air (or normal saline), careful continuation inserting needle, when ligamenta flava worn out by puncture needle, not only can feel " fall through sense ", and due to the negative pressure of epidural space, a small amount of air (or normal saline) in syringe also can be inhaled into epidural space, and this is epidural space distinctive " underbalance effect ".
Often a kind of glass injection with low resistance is equipped with in tradition epidural anesthesia bag, be different from general plastic injector for temporary use, frictional force between this kind of injector push-rod and syringe reduces greatly, Anesthetist can be made to experience the change of resistance more delicately when puncture needle enters epidural space from ligamenta flava, thus increase the success rate of epidural anesthesia.But judge that the change of resistance is a kind of subjective feeling of Anesthetist after all with said method, so the situation of epidural puncture failure often has generation, especially in the resident lacked experience, incidence rate is higher.
A kind of automatic detection epidural space syringe is had again to go on the market in recent years.This syringe is a kind of novel injector of built-in spring, syringe inside uses Compress Spring to maintain lasting pressure to pintle, by spring controlled push rod can when epidural puncture syringe needle enters epidural space from ligamenta flava automatic retraction, thus the traditional subjective feeling of Anesthetist to change in resistance is changed into the confirmation of visual effect.Meanwhile, this syringe also allows Anesthetist to make with the hands to be pushed ahead by anesthesia spinal needle, increases the stability of puncture, reduces and wears out spinal dural incidence rate.Compare and use automatic detection syringe and traditional glass syringe to judge that puncture enters the accuracy of epidural space, result shows, the application of automatic detection syringe can improve the accuracy judging to enter epidural space, also can reduce puncture needle and wear out spinal dural incidence rate.
The change in resistance that what but in above-mentioned automatic detection syringe, spring retraction also likely reflected is between its hetero-organization, but not the resistance that puncture needle enters epidural space from ligamenta flava disappears, thus cause the false judgment of Anesthetist; Need to exit puncture needle when detecting epidural space failure when again puncturing, syringe spring also can bounce back because of the change of resistance, thus needs again to draw back push rod connecting puncture needle again, thus adds the triviality of epidural puncture process; And the retraction force of spring is comparatively large, inertia may make the both hands controlling puncture needle continue the piercing needle at epidural space to push ahead, and increases and wears out spinal dural probability.
Summary of the invention
In order to overcome prior art Problems existing, the purpose of this utility model is to provide a kind of hard waist combined anesthesia puncture bag of automatic detection epidural space position, the subjective judgment of Anesthetist is organically combined with visual effect by this hard waist combined anesthesia puncture bag, puncture needle is avoided to penetrate spinal dura mater, effectively safer in patient, then more practical reliable in Anesthetist.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hard waist combined anesthesia puncture bag of automatic detection epidural space position, it is characterized in that: this hard waist combined anesthesia puncture handbag is drawn together with the push rod of teeth groove, spring, spring stop and injector syringe, the front portion of push rod extend in injector syringe through after spring stop, and being provided with piston on the top, front side of push rod, spring stop is fixed on injector syringe; Spring housing is contained on push rod, and the front end of spring is connected on piston, and rear end is connected on spring stop; Spring stop is provided with the snap close supporting with teeth groove.
In this utility model, described snap close comprises slide switch, buckles and rotating shaft kayser, and slide switch is connected on spring stop by rotating shaft, and buckleing kayser of matching with teeth groove is arranged on slide switch.The inclined-plane matched with teeth groove is provided with in the end of buckleing kayser.Slide switch is connected to spring stop by rotating shaft, is convenient to switch.When slide switch cuts out, buckleing kayser can teeth groove on fastening push rod thus stop push rod to be pushed ahead; When slide switch is opened, buckle be separated with push rod teeth groove kayser, under the action of the spring, push rod then can bounce back along with the disappearance of resistance.
During use, determine to open snap close after puncture needle enters ligamenta flava Anesthetist, push rod just can bounce back with spring, guarantees spring retraction power to control in the scope of a safety, avoids puncture needle to penetrate spinal dura mater.
This utility model designs a push rod snap close on spring stop, it can the teeth groove that is provided with of fastening push rod thus stop push rod to be pushed ahead, determine to open snap close after puncture needle enters ligamenta flava Anesthetist, push rod just can bounce back with spring, the visual effect that the position of the subjective judgment ligamenta flava of Anesthetist and resistance disappear is organically combined, makes the success rate of epidural anesthesia improve.The spring retraction power of syringe controlled in a comparatively safe scope, the impulse force avoiding retraction force excessive forces puncture needle to penetrate spinal dura mater.
The subjective judgment of Anesthetist is organically combined with visual effect by this utility model, effectively safer in patient, then more practical reliable in Anesthetist, can improve the success rate of epidural puncture, reduce the puncture time of epidural anesthesia.
