Abstract
The utility model relates to an improved double-tube puncture needle for spinal analgesia and epidural anesthesia, which belongs to the technical field of a medium inputting tube for medical use. The utility model is composed of two needle tubes which are parallel, and a needle core which is inserted in the needle tubes and can freely slide inside the needle tubes, wherein, the tube head of each needle tube is tapered, and pipeline openings are positioned on the tube wall. The tube tails of the two needle tubes are both provided with tube seats which cause the axial section of each whole needle to be Y-shaped. The utility model is used for completing spinal analgesia and epidural combined anesthesia by disposable puncture, and is also used for single anesthesia. The utility model can be used for lavaging body cavities. When the utility model is used, the puncture damage can not be caused, and the patients' pain can not be added.
Description
This utility model is a kind of improved ridge fiber crops---the two-tube puncture needle of epidural anesthesia, belongs to medical medium input pipe technical field.
The ridge fiber crops are united use, work along both lines with epidural anesthesia, have the superiority that a pin takes effect, thus be widely used clinically, but because of the single, double chamber gauge tap that designs on its needle stand complexity easy break-down too, if also be difficult to behind the blood contamination in the piercing process clean, be difficult to safeguard.And this pin manufacture difficulty is big, thereby two nook closing members arranged side by side are easily deformable has increased difficulty to puncture procedure for it, and it is anti-that its old-fashioned needle point also easily causes tissue to decrease in puncture.And existing two-tube pin generally has a needle stand, can not adjunction syringe injection after this needle stand is inserted epidural catheter, be unfavorable for implementing two pipe dispensing medicines, function singleness.
The purpose of this utility model provides a kind of improved ridge fiber crops---the two-tube puncture needle of epidural anesthesia, use this puncture needle the disposable spy of two needle tubings can be placed human body for the usefulness of implementing two pipe medicine dispensings at any time, neither can damage tissue, but one-object-many-purposes again.
This utility model is to implement like this, referring to accompanying drawing, ridge fiber crops---the two-tube puncture needle of epidural anesthesia, it is by having needle stand (1 successively, 2) nook closing member (3,4) with needle tubing (7,8) form, wherein needle tubing (7) is arranged side by side with needle tubing (8) cocurrent and parallel, radial section is the figure of eight, its improvements are, described needle tubing (7,8) end towards needle stand has and needle stand (1 successively, 2) base (5 of front end cone size coupling, 6), wherein needle tubing (7) is towards the tapered sealing in the other end termination of needle stand one end, and needle tubing (7) pipeline tapping (10) is positioned on the tube wall of needle tubing (7) termination.Because as the tapered sealing of syringe needle end face of above-mentioned needle tubing (7), pipeline tapping (10) is not at the tube head end face and at tube wall, damage tissue so plant the obstacle that can not occur or other levels generations porose when the pin of structure punctures human body because of tube head, and two-tube needle tubing respectively has a base but not a shared base, so can make the ridge fiber crops and the manipulating approaches of these two kinds of anesthesia of epidural anesthesia distinguish and keep apart, epidural space is put pipe in advance, capable again ridge fiber crops puncture and injection of medicine makes the ridge fiber crops and the superiority of epidural anesthesia interlock dispensing obtain reliable guarantee.But crosspointer inserts base simultaneously and implements dispensing or notes one suction again, makes its function obtain enlarging therefrom, for example expands being applicable to puncture lavation etc. to, realizes a thing and use more.
Below in conjunction with specific embodiment shown in the accompanying drawing to ridge fiber crops of the present utility model---the two-tube puncture needle of epidural anesthesia is further described.
Fig. 1 is the ridge fiber crops---the two-tube puncture needle structural representation of epidural anesthesia;
Fig. 2 be among Fig. 1 A-A to cutaway view.
Among Fig. 1-2, wherein:
1-needle stand 2-needle stand 3-nook closing member 4-nook closing member 5-base
6-base 7-needle tubing 8-needle tubing 9-link stopper 10-perforate
With reference to Fig. 1-2, the ridge fiber crops of this embodiment---the two-tube puncture needle of epidural anesthesia has the nook closing member (3 that two good stainless steel silks of the toughness of drawing materials are tailored, 4), wherein the size specification of the size specification of nook closing member (3) and No. 16 anesthesia spinal needles mates, its core print is taper, the size specification coupling of the size specification of nook closing member (4) and No. 9 ridge fiber crops pins, above-mentioned two nook closing members (3,4) the core tail has the same specification needle stand (1 of concentric welding with it in the same way and respectively successively, 2), the draw materials stainless steel tube of its caliber and nook closing member (3) diameter of section size coupling of the needle tubing of this embodiment (7) is tailored, its length also with nook closing member (3) length coupling, so can make nook closing member (3) insert its pipeline and in pipeline, be free to slide.Needle tubing (7) right-hand member is the metal enclosed mouth of pipe of tube head and is made into taper, and perforate (10) makes in distance vertebra top 10 millimeters and locates on the tube wall logically with the curved channel of needle tubing (7) pipeline, supports out perforate (10) to make things convenient for nook closing member (3) syringe needle.Needle tubing (7) left end is promptly managed tail pipe and is connect a tubular base (5), and its bullet was partly filled in base (5) so that be nook closing member (3) location when the needle stand (1) that makes nook closing member (3) inserted needle tubing with nook closing member.Then the draw materials stainless steel tube of its caliber and nook closing member (4) diameter of section size coupling of the needle tubing of this embodiment (8) is tailored, its length also with nook closing member (4) length coupling, so also can make nook closing member (4) insert its pipeline and in pipeline, be free to slide.Needle tubing (8) right-hand member be tube head with needle tubing (7) tube head in the same way and needle tubing (8) be unified into its cross section with the parallel weldering arranged side by side of needle tubing (7) and be the figure of eight as shown in Figure 2, needle tubing (8) tube head end face and needle tubing (7) tube head end face coplanar are vertebra shape.Needle tubing (8) left end promptly manage tail also pipe connect a tubular base (6), its taper was originally partly filled in base (6) so that be nook closing member (4) location when the needle stand (2) that makes nook closing member (4) inserted needle tubing with nook closing member.Since base (6) do not possess parallel with base (5) side by side have a space, jag makes this ridge fiber crops so needle tubing (8) is upward located radially outward apart from 90 millimeters on pipe tail---and the two-tube puncture needle axial section of epidural anesthesia is " Y " font, thrust the human body degree of depth for what effectively limit this puncture needle, on needle tubing (7, the 8) body in parallel on right side, the tortuous place of needle tubing (8) fixed trap a spacing colloid link stopper (9).Constitute thus of the present utility model should example ridge fiber crops---the two-tube puncture needle of epidural anesthesia be proved to be reasonable in design original through sample pin clinic trial, respond well, use it for one-time puncture and can finish ridge fiber crops and epidural anesthesia, also can carry out single anesthesia, need only in the piercing process and insert this pin at the human vertebra position, extract nook closing member then out, insert the syringe injection and get final product.Some puncture can realize two-way administration, enlarges the anesthesia scope, and this pin do not cause penetration damage, does not increase patient's misery.In addition, this pin is worked along both lines because of its two-tube two-seat structure, and one injects a suction so also can make the usefulness of body cavity lavation or samples of CSF collection.
