Abstract
The utility model discloses a segmental epidural catheter with a spiral supporting wire. The segmental epidural catheter comprises a transparent plastic catheter with scale marks, wherein the insertion end of the transparent plastic catheter is sealed, and side medicine holes are formed in both sides of the insertion end. The segmental epidural catheter is characterized in that the spiral supporting wire with a soft folding angle is arranged in the transparent plastic catheter, and a soft supporting wire is arranged in a position which is away from the insertion end of the transparent plastic catheter for 7 cm. The segmental epidural catheter has the advantages of reasonable structure, novel design high safety and good comfortableness; because the spiral supporting wire is arranged in the transparent plastic catheter, the transparent plastic catheter cannot be squashed in the process of use, the circulation is smooth, and the anesthetic effect is good; additionally, the soft folding angle can be easily bent without folding, and the flexibility of the soft supporting wire is high, so as to prevent epidural nerves from being compressed after imbedding. By using the segmental epidural catheter, the technical problems of poor anesthetic effect, poor safety, low comfortableness and time and labor consumption in operation of the prior art are solved.
Description
Technical fieldThis utility model belongs to Medical anesthetic utensil technical field, is specifically related to a kind of segmental epidural catheter with the spiral branches support wire.
Background technologyEpidural block of the prior art is a kind of anesthesia of wide clinical application, have in simple to operate, with low cost, art and be easy to management, the postoperative advantage such as Epidural analgesia of being convenient to, but there is shortcomings in the anesthetic tube that this anesthesia is used when operation, because conduit is plastic material, during operation, easily be crushed or be converted into dead angle, cause path to be closed, anaesthetic effect is poor; When the hardness of conduit material was high, conduit was easy to insert human body, but poor tissue blood vessel, the nerve of easily stabbing of flexibility ratio even broken spinal dura mater, and blood vessel occurs that the phenomenon of damage is particularly outstanding, poor stability; When the hardness of conduit material was hanged down, flexibility ratio was high, but conduit is not easy to insert spinal epidural cavity, and, insert rear easy bending and even tie a knot, cause conduit to take out, operation is wasted time and energy; Epidural intraluminal tissue that segmental epidural catheter is finally inserted is soft and be rich in nerve, and conventional catheters is inserted rear easy compressing spinal epidural cavity nerve, causes patient's comfort level poor.
Summary of the inventionThe purpose of this utility model be solve that prior art exists that anaesthetic effect is poor, poor stability, comfort level is low and operation is wasted time and energy technical problem, provide a kind of segmental epidural catheter with the spiral branches support wire, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of segmental epidural catheter with the spiral branches support wire of this utility model, it comprises the transparent plastic conduit with reticule; The insertion end sealing of described transparent plastic conduit, the both sides of insertion end are provided with the side medicine outlet hole; Its main points are in described transparent plastic conduit, to be provided with the spiral branches support wire with soft knuckle; Apart from described transparent plastic conduit insertion end 7cm section place, be provided with the soft supporting silk.
In order to improve anaesthetic effect, the insertion end of described transparent plastic conduit is opening-like.
This utility model is rational in infrastructure, novel in design, because the inside of transparent plastic conduit is provided with the spiral branches support wire, in use procedure, can not be crushed, and path is smooth and easy, and anaesthetic effect is good; And soft knuckle is can be easily crooked and can not give a discount, and the flexibility ratio of soft supporting silk is also high, can prevent from inserting rear compressing to the spinal epidural cavity nerve, and is safe, comfort level is good.This utility model has solved that the prior art anaesthetic effect is poor, poor stability, comfort level is low and operation is wasted time and energy technical problem.
The accompanying drawing explanationFig. 1 is the main cutaway view of looking of structural representation of the present utility model;
Fig. 2 is the main cutaway view of looking of the opening-like structural representation of this utility model.
In figure 1, side medicine outlet hole 2, soft supporting silk 3, transparent plastic conduit 4, spiral branches support wire 5, soft knuckle
The specific embodimentWith reference to Fig. 1, it comprises the transparent plastic conduit 3 with reticule this utility model; The insertion end sealing of described transparent plastic conduit 3, the both sides of insertion end are provided with side medicine outlet hole 1; In described transparent plastic conduit 3, be provided with the spiral branches support wire 4 with soft knuckle 5; Apart from described transparent plastic conduit 3 insertion end 7cm section places, be provided with soft supporting silk 2.
With reference to Fig. 2, the insertion end of described transparent plastic conduit 3 can be set to the opening shape.
This utility model is mainly used in epidural anesthesia and lumbar cistern drainage, owing in the transparent plastic conduit, being provided with the spiral branches support wire, in use procedure, can not be crushed, and can guarantee that path is smooth and easy, improves anaesthetic effect; Simultaneously, the soft supporting silk spacing of spiral branches support wire insertion end is large, and pliability is easy to insert well, and the compressing that produces when inserting relatively soft spinal epidural cavity nerve is little, can prevent injured blood vessel and nerve, and patient's comfort level is high; Soft knuckle spacing on the spiral branches support wire is large, hardness is little, suppleness good, bending conduit easily after inserting, can not produce the phenomenon that curved transitions causes conduit folding flat one-tenth dead angle, and the spacing of soft knuckle is large, also be beneficial to the doctor and when importing, by the transparent plastic conduit, observe the mobility status of medicinal liquid, thereby judge whether medicinal liquid has the phenomenon of stop; In order to improve anaesthetic effect, the insertion end of transparent plastic conduit is set to the opening shape as required in clinical use procedure.
Of the present utility model rational in infrastructure, cost of manufacture is low, easy and simple to handle, and anaesthetic effect is high, and patient's comfort level is high, is beneficial on a large scale and promotes the use of.
The soft head section of the large formation of the interval of the supporting wire at the insertion end 7cm section place of the bright plastic catheter 3 of utility model; As seen from Figure 1, the sealing of conduit insertion end, be provided with three side medicine outlet holes 1 at front 20mm place; As seen from Figure 2, insertion end is open, and medicine outlet hole is the mouth of pipe; The large observable medicinal liquid of soft knuckle 5 place's spiral branches support wire interval, can be considered observation window.The position of observing the medicinal liquid transporting velocity at needs widens the interval of spiral branches support wire, by transparent plastic bushing, can be observed the mobility status of this place's medicinal liquid.
