Description
Technical field
This utility model relates to medical instruments field, particularly a kind of bladder-type cavum epidural puncture pointer.
Background technology
Epidural space nerve block anesthesia is the anesthesia often used, and in this anesthesia, a very important step is that epidural puncture needle is punctured to epidural space accurately.Epidural space is negative pressure, and pressure (EDP) value is about-1 ~-3cmH2O.When doing spinal epidural cavity puncture clinically, anesthetist uses the direct connecting puncture needle of ordinary syringe to carry out cavum epidural puncture to patient, organize between needle tip approach skin, subcutaneous tissue, supraspinal ligament, sour jujube, after arriving ligamenta flava, could epidural space be arrived.If inserting needle is excessively shallow, then do not reach anaesthetic effect.If inserting needle is excessively dark, penetrates epidural space and enter gap under spinal dura mater, even enter subarachnoid space through arachnoidea, thus cause the outflow of cerebrospinal fluid.With Subdural space anesthesia or subarachnoid anesthesia meeting appreciable impact breathing, heartbeat and other vital functionss on dura mater.In order to improve anesthesia efficiency, reduce anesthetic risks, narcot officer had done a large amount of clinical researches in recent years, multiple inventive method is provided to epidural space location, as air vesicle indication, pressure measuring alarm method, differential friction determining method, pressure strengthens indication, hanging drop determining method, but these methods exist open defect, and practical operation is more difficult.
China Patent Publication No. is CN2244917Y, the patent document of " anesthesia spinal needle " by name discloses a kind of epidural puncture needle, include needle body and the solid nook closing member for preventing needle tubing from blocking, in actual mechanical process, in order to realize accurate location, in puncture procedure, puncture needle extracts nook closing member out after advancing certain distance, connect wave duct again or syringe positions test, as do not arrived, then need to insert again after nook closing member continues propelling one segment distance and repeat above operation again.Although the method can realize judging whether puncture needle arrives epidural space, but repeatedly extract nook closing member out due to needs and connect wave duct or syringe test position fix repeatedly again, operating process is loaded down with trivial details, and in inserting needle process, synchronously can not judge whether puncture needle arrives epidural space, easily causes error.
Utility model content
This utility model provides a kind of bladder-type cavum epidural puncture pointer, realizes synchronously judging whether puncture needle arrives epidural space in inserting needle process.
The technical solution adopted in the utility model is:
Bladder-type cavum epidural puncture pointer, comprise needle body, nook closing member and air bag, described needle body afterbody is needle body handle, described nook closing member is hollow structure, and described nook closing member inside is pin in nook closing member, and described air bag front end is balloon interface, described balloon interface is closed by gasbag plug, in described nook closing member, pin is by gasbag plug communicated air bags, and described nook closing member afterbody is nook closing member interface, and described nook closing member interface mates with balloon interface.
Further, described needle body and nook closing member front end are cambered design.
Further, described nook closing member front end is provided with nook closing member opening, and described nook closing member opening is arranged on the side of nook closing member front end.
Preferably, described gasbag plug is rubber stopper.
Preferably, the sealing on described air bag top is elastica.
The beneficial effects of the utility model are:
1, nook closing member is hollow structure, front end cambered design, and passivity is smooth, little to the damage of tissue in piercing process;
2, nook closing member front opening is in side, can not block nook closing member because being strayed into tissue in nook closing member in piercing process;
3, air bag upper seal adopts elastica design.When the bladder inflates, elastica projection is in hemispherical, and after gas flows out, elastica is smooth, facilitates direct vision;
4, needle body front end is the cambered design adapted with nook closing member, and convenient direction is on demand to epidural space administration or put pipe.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is this utility model bladder-type cavum epidural puncture pointer schematic diagram.
Fig. 2 is the air bag unaerated schematic diagram of this utility model bladder-type cavum epidural puncture pointer.
Fig. 3 is schematic diagram after the airbag aeration of this utility model bladder-type cavum epidural puncture pointer.
In figure: 1, needle body, 2, needle body handle, 3, nook closing member, 4, nook closing member opening, 5, pin in nook closing member, 6, air bag, 7, balloon interface, 8, rubber stopper, 9, elastica, 10, nook closing member interface.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, this utility model discloses a kind of bladder-type cavum epidural puncture pointer, comprise needle body 1, nook closing member 3 and air bag 6, described needle body 1 afterbody is needle body handle 2, needle body handle 2 handled easily, described nook closing member 3 is hollow structure, described nook closing member 3 inside is pin 5 in nook closing member, described air bag 6 front end is balloon interface 7, and described balloon interface 7 is closed by gasbag plug, in the present embodiment, gasbag plug is rubber stopper 8, facilitate in nook closing member that pin 5 is by rubber stopper 8 communicated air bags 6, described nook closing member 3 afterbody is nook closing member interface 4, and described nook closing member interface 4 mates with balloon interface 7.
Described needle body 1 and nook closing member 3 front end are cambered design, and convenient direction is on demand to epidural space administration or put pipe, needle body 1 and nook closing member 3 front end cambered design, and passivity is smooth, little to the damage of tissue in piercing process.
Described nook closing member 3 front end is provided with nook closing member opening 4, and described nook closing member opening 4 is arranged on the side of nook closing member 3 front end.
As shown in Figures 2 and 3, in the present embodiment, the sealing on described air bag 6 top is elastica 9.
This utility model using method: before use, first extracts a certain amount of air in the rubber stopper injection air bag 6 of air bag 6 with asepsis injector, extracts syringe, make the elastica 9 on air bag 6 top projection in hemispherical for subsequent use.The needle body 1 of puncture needle inserts the rear row cavum epidural puncture of nook closing member 3, when needle body 1 enter subcutaneous after, by nook closing member interface 10 closed butt joint of balloon interface 7 with nook closing member 3 tail end, in nook closing member in nook closing member interface 10, pin 5 thrusts in air bag 6 through the rubber stopper 8 of balloon interface 7, air bag 6 and nook closing member 3 are connected as a single entity, progressively slow inserting needle, observe the elastica 9 on air bag 6 top, when puncture needle enters epidural space, gas in air bag 6 is sucked epidural space by the negative pressure of epidural space, elastica 9 declines rapidly, thus provides clear and definite instruction for puncture person.Puncture successfully, nook closing member 3 is extracted together with air bag 6.
Connecting wave duct or syringe test position fix repeatedly again without the need to repeatedly extracting nook closing member 3 out in this utility model piercing process, can realize synchronously judging whether puncture needle arrives epidural space in inserting needle process simultaneously.
Above-described this utility model embodiment, does not form the restriction to this utility model protection domain.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
