Abstract

The utility model provides a spring bolt type positive pressure epidural puncture monitor which is used for the monitoring of whether a puncture needle enters into the epidural space or not when conducting the epidural puncture anesthesia. The utility model is provided with a tube body (2) which is provided with a joint (1), an embolism (3) is arranged in the tube body, and a casing (4) is arranged at the external side of the tube body. A spring (5) is arranged between the rear part of the embolism and the casing, the casing is provided with a cross slot (6), a shifting handle which is fixed together with the embolism (3) is arranged in the cross slot. The spring bolt type positive pressure epidural puncture monitor has the advantages of visual and accurate display, high sensitivity, convenient use, easy operation and easy fabrication.

Description

弹簧栓式正压硬膜外穿刺监测器 The latch epidural positive pressure monitor

本实用新型提供了一种硬膜外穿刺监测器,用于硬膜穿刺麻醉时,对穿刺针是否进入硬膜外腔的监测。 The present invention provides a monitor when one kind of epidural, subdural puncture anesthesia, monitoring of whether the puncture needle into the epidural space.

硬膜外麻醉是目前应用较广泛的麻醉方法。 Epidural anesthesia is the widely used method of anesthesia. 其麻醉效果与准确穿刺密切相关,而穿刺时的监测即判断穿刺针是否进入硬膜外腔是准确穿刺的条件。 Its anesthetic effect is closely related to the accurate puncture, when the puncture that is monitored to determine whether the puncture needle into the epidural space conditions are accurate puncture. 自硬膜外麻醉用于临床以来,对其监测的主要手段是依据硬膜外腔产生的负压,用一玻璃管注水接在硬膜外穿刺针上观其波动来监测,对负压不明显者常需反复验证。 Since epidural anesthesia for clinical use since its main means of monitoring is based on the negative pressure generated epidural space, with a glass tube connected to the water view of the epidural needle to monitor its fluctuations, negative pressure is not obvious often need repeated verification. 操作繁琐且不准确。 Cumbersome and inaccurate operation. 因此多年来人们为找到灵敏度高的监测器而做过许多尝试,但思路多从硬膜外腔负压方面考虑,准确性仍受穿刺时有无负压的影响。 So over the years as people find high sensitivity detectors and done a lot of attempts, but thinking more from the negative aspects of the epidural space considerations, whether the negative impact upon the accuracy of the still subject to puncture.

本实用新型的目的是提供一种弹簧栓式正压硬膜外穿刺监测器,以提高监测的准确性和方便性。 The object of the present invention is to provide a latch of epidural positive pressure monitor, to improve the accuracy and ease of monitoring.

本实用新型是这样实现的,它有一个带接头的管体,管体内有栓塞,管体外有外壳,栓塞后端与外壳之间有弹簧,外壳上有横槽,与栓塞固定在一起的拨柄安装有横槽内。 The present invention is achieved, it has a tubular body with connectors, the tubular body has a plug, the pipe body with a housing, and a spring between the rear end of the plug housing, the housing has lateral grooves, together with the dial plug shank mounted transverse groove.

由于硬膜外腔是潜在腔隙,内有疏松结缔组织填充,尽管穿刺时某个节段负压不明显,但腔内压力比其它组织低。 Because the epidural space is a potential cavities, there are filled with loose connective tissue, although puncturing a negative pressure section is not obvious, but the pressure in the chamber is lower than the other tissues. 因此,使用这种监测器时,可利用拨柄向后拨动栓塞,弹簧弹力就对栓塞有一个向前的推动力。 Thus, using such a monitor may be utilized dial grip toggle plug rearwardly, the spring force will have a forward driving force to the plug. 当穿刺针未进入硬膜外腔时,阻力大于该推动力,栓塞不动。 When the puncture needle into the epidural space is not, the resistance is larger than the urging force, the plug does not move. 当进入硬膜外腔时,腔内压力变小,低于该推动力时,栓塞就会在推动力的作用下前移,带动拨柄前移,就会显示出穿刺针已进入硬膜外腔。 Upon entering the epidural space, the pressure chamber becomes smaller, below which the urging force, the plug will move forward under the action of the driving force, shifting handle driven forward, it will show the needle has entered the epidural cavity. 这种监测器显示直观、准确,灵敏度高,不受硬膜外腔内有无负压或负压大小的影响,使用方便,操作容易,制造简单。 Such visual display monitor, accurate, sensitive, whether or not the epidural space of negative pressure or negative affect size, easy to use, easy to operate, simple to manufacture.

下面结合附图及实施例说明本实用新型的具体结构。 Description of the present invention and the specific configuration of the embodiment below with reference to the accompanying drawings.

图1是本实用新型结构的剖视图。 FIG. 1 is a sectional view showing the structure of the present invention. 图2是其主视图。 2 is a front view of FIG. 图3是其俯视图。 FIG 3 is a plan view.

如附图所示,本实用新型之弹簧栓式正压硬膜外穿刺监测器有一个带接头(1)的管体(2),管体(2)内有栓塞(3),管体外有外壳(4),栓塞后端与外壳之间有弹簧(5),外壳上有横槽(6),与栓塞(3)固定在一起的拨柄(7)安装在横槽(6)内。 As shown, the latch of the present invention, the positive pressure reference monitor epidural with a joint (1) of the tube (2), the tubular body (2) with a plug (3), the tube vitro a housing (4), there is between the rear end of the plug housing and the spring (5), has lateral grooves (6), the plug (3) held together shifting handle (7) mounted in the lateral grooves (6) on the housing.

使用时,将拨柄(7)向后拨起,接头(1)与穿刺针相连,如果穿刺针进入硬膜外腔,由于腔内压力低,栓塞就会前移,与其固定在一起的拨柄也会前移。 In use, the shifting handle (7) rearwardly pulling up connected connector (1) and the needle, if the needle into the epidural space, due to the low pressure chamber, the plug will be moved forward, together with its dial will handle forward.

管体(2)由透明材料制成,栓塞为深颜色。 The tubular body (2) made of transparent material, the plug is a dark color. 这样可以清楚地看到栓塞的移动情况,显示更直观明显。 This can clearly see the movement of the plug, display significantly more intuitive.
