Description
Technical field
The utility model belongs to field of medical equipment technology, and more particularly to a kind of peridural anesthesia conduit connects
Head.
Background technology
Epidural block anaesthetize, will local anaesthetics injection spinal epidural cavity, block spinal nerve root, temporarily make which
Paralysis, referred to as referred to as Epidural block anesthesia, epidural anesthesia are produced with region.But, by existing fiber crops
When liquor-saturated pipe joint carries out anesthesia injection, between syringe and joint, will there is certain pressure differential, the pressure differential is not easy to
Anesthetist is grasped and injects dynamics so as to be difficult to anticipation rate of administration.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, there is provided one kind is slowly injected into can arcotic
Peridural anesthesia pipe joint.
The purpose of this utility model is achieved through the following technical solutions.
A kind of peridural anesthesia pipe joint, including adapter body and protective cover, the protective cover are arranged on joint master
The upper end of body, the side wall of the adapter body are provided with side and connect hole, and the inside of the adapter body is disposed with from top to bottom
Reverse taper hole, through hole, bellmouth and the cylindrical hole being interconnected, the reverse taper hole, through hole, bellmouth and cylindrical hole are coaxial
Arrange, the internal diameter of the cylindrical hole is more than the internal diameter of bellmouth big opening end, the internal diameter at the bellmouth osculum end is interior with through hole
Footpath is equal, and spaced convex globoidal and cancave cambered surface, the convex globoidal and cancave cambered surface are provided with the inwall of the reverse taper hole
Junction be provided with annular protrusion, be provided with irregular projection on the inwall of the bellmouth, arrange in the cylindrical hole
There is kuppe, between the kuppe and the big opening end of bellmouth, form water conservancy diversion cavity.
Further, the kuppe is fixedly connected with the inwall of cylindrical hole.
Further, annular protrusion section in its axial direction is semicircle.
Further, the side connects hole for stepped throughhole.
The beneficial effect that the utility model is produced due to taking above-mentioned technological means is：Epidural of the present utility model
Anesthetic tube joint, by arranging convex globoidal, cancave cambered surface and annular protrusion in reverse taper hole, anesthesia liquid flows in joint and touches
Annular protrusion is hit, annular protrusion dispersion liquid stream slows down the flowing velocity of liquid, plays a part of current stabilization；Up and down the two of through hole
Side is respectively provided with reverse taper hole and bellmouth, the fine dispersion liquid stream of stable state can be produced with less energy ezpenditure, just
Injecting in liquid；The internal diameter of cylindrical hole is more than the impulsive force that the internal diameter of bellmouth can effectively disperse liquid fluid；By
Irregular projection is set on the inwall of bellmouth, and this irregular shape can improve liquid flow direction, disperses impact forces prevent medicine
Liquid is concentrated and pours in a direction；By arranging kuppe in cylindrical hole, the kuppe define one obstruct liquid fluid lead to
The water conservancy diversion cavity crossed, the energy that can consume liquid fluid are slowly injected into arcotic so as to reduce Fluid pressure, finally.
Description of the drawings
Fig. 1 is the structural representation of peridural anesthesia pipe joint of the present utility model.
In figure, 1- adapter bodies, 2- protective covers, 3- sides connect hole, 4- reverse taper holes, 5- through holes, 6- bellmouths, 7- cylindricalitys
Hole, 8- convex globoidals, 9- cancave cambered surfaces, 10- annular protrusions, 11- projections, 12- kuppes, 13- water conservancy diversion cavitys.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement
Example is described in further detail to the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With new, it is not used to limit the utility model.
Peridural anesthesia pipe joint of the present utility model is as shown in figure 1, including adapter body 1 and protective cover 2, protection
Cover 2 is arranged on the upper end of adapter body 1, and the side wall of adapter body 1 is provided with side and connects hole 3, and side connects hole 3 and is preferably stepped leading to
Hole, the inside of adapter body 1 are disposed with reverse taper hole 4, through hole 5, bellmouth 6 and the cylindrical hole being interconnected from top to bottom
7, to be coaxially disposed, the internal diameter of cylindrical hole 7 is more than 6 big opening end of bellmouth for reverse taper hole 4, through hole 5, bellmouth 6 and cylindrical hole 7
Internal diameter, the internal diameter at 6 osculum end of bellmouth are equal with the internal diameter of through hole 5, are provided with spaced convex on the inwall of reverse taper hole 4
The junction of cambered surface 8 and cancave cambered surface 9, convex globoidal 8 and cancave cambered surface 9 is provided with annular protrusion 10, and annular protrusion 10 is in its axial direction
Section be semicircle, be provided with irregular projection 11 on the inwall of bellmouth 6, be provided with kuppe 12 in cylindrical hole 7, lead
Stream cover 12 is fixedly connected with the inwall of cylindrical hole 7, and water conservancy diversion cavity 13 is formed between the big opening end of kuppe 12 and bellmouth 6.
