Abstract

The utility model relates to a guide type epidural anesthesia puncture needle which comprises a puncture steel needle, a needle seat, a needle handle, a monitoring guide pipe and a straight through pipe. The puncture steel needle is connected with the machine end of the needle seat, the needle handle is in a lateral wing shape and arranged on the needle seat, a Y-shaped branch is arranged at the upper end of the needle seat, the upper end of the needle seat is connected with the monitoring guide pipe, the straight through pipe is arranged at the other end of the needle seat, the straight through pipe is provided with a standard port, an anesthesia guide pipe can be arranged in the straight through pipe through the standard port, and the straight through pipe can be connected with a medical three-way connector, an syringe and the like. The guide type epidural anesthesia puncture needle has the advantages of being capable of visually guiding an epidural space puncture process, being matched with an epidural anesthesia monitoring sleeve set to effectively monitoring an epidural space puncture pipe and an anesthesia maintaining process, enabling a doctor to have objective monitoring indexes to judge whether an epidural puncture and anesthesia state is normal, enabling epidural space anesthesia to be finished under the visual control in the full process and effectively preventing and reduces or avoiding anesthesia complication.

Description

The guiding epidural anaesthetic puncture needle

Technical field

This utility model relates to the guiding epidural anaesthetic puncture needle in a kind of epidural space anesthetic puncture.

Background technology

Extradural nerve block is the most general a kind of anaesthesia technology of domestic application, and the primary prerequisite of its success is that local anaesthetics injects spinal epidural cavity.Therefore determine that it is its crucial sport technique segment that puncture needle and hard external conduit enter the epidural gap.So far,, because hard outer retardance is a blind spy puncture and intubation technology, all rely on Anesthetist's feel and clinical experience.Existing judgement enters method and the report of epidural space, all belongs to indirect non-specific method, there is no visual index and objective parameter as indication directly perceived.Clinical indication commonly used such as ligamenta flava are broken through sense at present, and bubble compression test etc. is the indirect non-indication that judges intuitively, meets to such an extent that more its success rates are higher, therefore Clinical significance of MG is not strong.After relying on injection fully, anesthesia success or failure, effect and complication could confirm, particularly normal puncture inconspicuous and conduit are worn out spinal dura mater before the anesthesia injection, when anaesthetic injects blood vessel or subarachnoid space, the severe complications such as the full spinal anesthesia (0.24%), toxic reaction, spinal cord or the nerve injury that cause are that the narcot officer pays close attention to and the hot issue of studying always.It is reported, be still the main source of China's complication of anesthesia and anesthesia accident at present.Use is closed in this patented technology and the assembly of epidural space Anesthesia Monitoring cover can have great breakthrough to existing epidural space anesthesia, has important clinical value.

The utility model content

This utility model can guide epidural space puncture overall process, closing use with the assembly of epidural space Anesthesia Monitoring cover can effectively monitor the epidural space anesthetic puncture, locate, put pipe and anaesthetize and keep overall process, allow the doctor have objective monitoring index to judge that epidural space punctures, locates, puts pipe and whether narcotism is normal, epidural space anesthesia whole process is all completed under directly perceived the control, effectively prevented and reduce or avoid the generation of complication of anesthesia; Also reduce the troublesome operation that need pull up threeway when inserting anesthetic tube, thereby also reduced the anesthetic tube that therefore operates and cause, be strayed into the danger of blood vessel.

The technical scheme in the invention for solving the technical problem is:

A kind of guiding epidural anaesthetic puncture needle, it comprises: puncture draw point, needle stand, needle handle, monitoring tube, straight pipe form; The draw point that wherein punctures is connected with the needle stand machine end, and needle handle is side Ji morpheme on needle stand, and there is Y shape branch the needle stand upper end, connect monitoring tube, the other end is straight pipe, and it is standard interface, anesthetic tube be can insert from here, Medical tee joint, syringe etc. also can be used for connecting.

Described puncture draw point, needle handle are identical with the conventional medical anesthesia spinal needle, and the above is with scale.

Described monitoring tube is opened on the needle stand side, branch is connected with Y shape, can be connected with epidural space Anesthesia Monitoring cover group, synchronous direct-view monitor, the observation puncture needle enters different tissues and enters epidural space location indication procedure for displaying and monitoring anaesthesia process at once, in order to keep good narcotism; Also can be used for observing and reflux.

Described straight pipe is positioned at the needle stand the top, and straight-through mutually with the puncture draw point, pavilion enters the nucleic acid conduit from here, also can connect Medical tee joint.

Guiding epidural anaesthetic puncture needle described in the utility model, in use, by the doctor, monitoring tube is connected with epidural monitoring cover group, then puncture, observe the monitor display while puncturing, when the corresponding waveform of hard epidural space occurring, namely when doctor's puncture to having on fall through sense or monitor when the demonstration of dynamic pressure waveform image is arranged, its pressure is shown as ± 20cmH ₂Prove in the o scope that puncture needle has reached epidural space, prompting is punctured successfully, but just begin column is put anesthetic tube.Extract puncture needle, fixedly anesthetic tube; Extract the 3ml normal saline with syringe and inject epidural space by the Medical tee joint device, observe the backflow situation, whether the position of proving again anesthetic tube is normal; All show and meet the index parameter scope as the dynamic pressure waveform of monitor and medicinal liquid return channel internal reflux character, just can inject corresponding anaesthetic to patient, need not traditional troublesome operation.

Description of drawings

Fig. 1 is perspective view of the present utility model;

The specific embodiment

As shown in Figure 1, a kind of guiding epidural anaesthetic puncture needle of the present utility model, it comprises: puncture draw point 1, needle stand 2, needle handle 3, monitoring tube 4, straight pipe 5 form; The draw point 1 that wherein punctures is connected with needle stand 2 machine ends, and needle handle 3 is side Ji morpheme on needle stand 2, and there is the 2-1 of Y shape branch needle stand 2 upper ends, connect monitoring tube 4, the other end is straight pipe 5, and it is standard interface, anesthetic tube be can insert from here, Medical tee joint, syringe etc. also can be used for connecting.

Described puncture draw point 1, needle handle 2 are identical with the conventional medical anesthesia spinal needle, and the above is with scale.

Described monitoring tube 4 is opened on needle stand 2 sides, be connected with the 2-1 of Y shape branch, can be connected with epidural space Anesthesia Monitoring cover group, synchronous direct-view monitor, the observation puncture needle enters different tissues and enters epidural space location indication procedure for displaying and monitoring anaesthesia process at once, in order to keep good narcotism; Also can be used for observing and reflux.

Described straight pipe 5 is positioned at needle stand 2 the tops, and is straight-through mutually with puncture draw point 1, can insert from here anesthetic tube, also can connect Medical tee joint.

Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model, when the function that produces does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
