Abstract
The utility model discloses a controllable epidural anesthesia pipe of district's section, in the dura mater outer catheter front end outside, add two be used for epidural space that the shutoff corresponds independently overlap the bag, cover nang bao is around dura mater outer catheter to hug closely the body, there is the side opening that is used for injecting into the local anesthetic medicine at two dura mater outer catheter bodies that independently overlap between the bag, the cover bag respectively through the suction route with aerify or the topping up physically controlling means be connected, the suction route is walked in dura mater outer catheter. The utility model discloses it is poor to solve the level of anesthesia controllability, the dosage technical problem that waits bigger than normal.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly a kind of epidural anaesthesia device.
Background technology
Epidural anesthesia is clinical practice the most a kind of anaesthesia technology at present, and epidural anesthesia is divided into single method and continuity method two kinds.The single genealogy of law punctures successfully and predetermined local anaesthetics is all injected successively epidural space to produce anesthetic action.This method lacks controllability, easily severe complication occurs, therefore seldom used.Continuity method is the most frequently used epidural anesthesia method, is to develop on the basis of single, by puncture needle, at epidural space indwelling one conduit, and the divided doses or continue medication according to operating time length, thus anesthesia duration is extended.But also there is a shortcoming in continuity method, its level of anesthesia poor controllability, be easy to occur level of anesthesia is too high thus cause patient breathing cycle's complication or level of anesthesia too low, requirements of operation can not be met, perform the operation for some special postures, epidural anesthesia is unsatisfactory especially for the control of plane.
Summary of the invention
The purpose of this utility model is to provide the controlled segmental epidural catheter of a kind of section, to solve level of anesthesia poor controllability, and the technical problems such as dosage is bigger than normal.
In order to realize foregoing invention object, the technical scheme that this utility model adopts is as follows:
The controlled segmental epidural catheter of section, at epidural catheter front end outer side, add two independent cuffs being used for epidural space corresponding to shutoff, described cuff wraps in around epidural catheter, and is close to body; Epidural catheter body between two independent cuffs has the side opening injecting local anesthetic; Described cuff is connected with inflation or topping up member control apparatus respectively by suction path, and described suction path walks in epidural catheter.
The termination of first cuff in described epidural catheter front end is cecum, second cuff and first cuff at a distance of 3-5cm, described side opening symmetry be distributed in conduit both sides.
Described epidural catheter body has the striped of mark scale, is provided with some steel rings preventing catheter body to be out of shape in the back segment body of epidural catheter.
Effect of the present utility model is by improving existing segmental epidural catheter, Anesthetist better can be controlled the level of anesthesia of operation, not only meet requirements of operation but also can complication of anesthesia be reduced, reduce the consumption of anesthetics simultaneously, increase comfortableness and the satisfaction of patient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view along A-A direction of Fig. 1.
Detailed description of the invention
Structure of the present utility model is see shown in Fig. 1,2.This utility model provides the controlled segmental epidural catheter of section, and its technical scheme is: add two independent cuffs at epidural catheter front end outer side, is used for epidural space corresponding to shutoff.Catheter body between two independent cuffs has side opening, in order to inject local anesthetic.Cuff can be expanded by inflation or topping up body, plays plugging action, and after cuff suction, cuff can fit together completely with conduit, there is not gap, and cuff is repeatedly aspirated and can not be out of shape.Distance between two cuffs is between 3-5cm, and this length is applicable to peridurally putting length of tube.Cuff is made up of high-molecular biologic film, cuff has transparent, anti, and lubricity is good, plasticity is strong, good airproof performance, bio-safety, stablizes wear-resisting feature, reduce the resistance that conduit cuff walked in epidural and extract conduit, reducing thrombosis, dropping to minimum to the injury of human body, having very high use value.Catheter body has the striped of mark scale.Be provided with some steel rings in catheter body, prevent catheter body to be out of shape.
This gives the controlled segmental epidural catheter of section as shown in Figure 1, be provided with first cuff 4 in the controlled segmental epidural catheter front end of section, its termination is cecum, and the first cuff 4 wraps in around body, and is close to body.
The suction path 3 of the first cuff 4, be connected with the first cuff 4, walk in catheter body, its outer end is connected with sleeve bag gas-filling valve 1.Second cuff 2, wraps in around body, with first cuff 4 at a distance of 3cm, is close to body.
The suction path 6 of the second cuff 2, is connected with the second cuff, walks in catheter body, and its outer end is connected with sleeve bag gas-filling valve 7.Shown in Fig. 2.
Between two cuffs, body has side opening 5, side opening 5 symmetry be distributed in conduit both sides, for injecting local anaesthetics.
After epidural puncture completes, local anaesthetics can be fixed between two cuffs by inflatable cuff, play section anaesthetic effect, meet requirements of operation.If operative site is comparatively large, exceedes the anesthesia scope between two cuffs, can single sleeve bag gas-filling have been passed through, anesthetics one direction is run, played anesthetic action, strengthened injection anaesthetic amount and make more than inflatable cuff or following level of anesthesia reach requirements of operation.
This utility model can make anesthesia more accurate, and can anesthetics be saved, effectively solve and that the occur complication of breath cycle excessive due to level of anesthesia scope, the controllability of epidural anesthesia is strengthened greatly, while reducing anesthetic risks, adds the comfortableness of patient.
