Abstract
本实用新型公开了软头麻醉导管，包括导管本体，导管本体的头部为软化段，软化段的硬度小于导管本体，软化段的长度为2mm～8mm，导管本体的外径为0.5mm～3.0mm，内径为0.2mm～1.8mm，导管本体和软化段均采用PVC制成。本实用新型麻醉导管头部的软化段柔软且具有弹性，柔软度可控，其硬度小于导管本体，在临床上应用头部软化处理的麻醉导管，在插入人体时，其管端遇阻力会自行改变方向，将导管引向低阻力间隙，大大降低刺透的风险，增加麻醉导管的安全可靠性。头部经软化的麻醉导管与头部未经软化处理的相比较有明显的软化弹性效果，在临床上具有很高的实用价值。
The utility model discloses a soft-tip anesthesia catheter, which comprises a catheter body. The head of the catheter body is a softening section, the hardness of the softening section is smaller than that of the catheter body, the length of the softening section is 2mm-8mm, and the outer diameter of the catheter body is 0.5mm-3.0mm. mm, the inner diameter is 0.2mm ~ 1.8mm, the catheter body and softening section are made of PVC. The softening section of the head of the anesthesia catheter of the utility model is soft and elastic, and its softness is controllable. Change the direction and lead the catheter to the low-resistance gap, greatly reducing the risk of puncture and increasing the safety and reliability of the anesthesia catheter. Compared with the unsoftened head, the anesthesia catheter with softened head has obvious softening and elastic effect, and has high practical value in clinical practice.
Description
Technical field
This utility model relates to the anesthetic tube that uses in a kind of clinical medicine technical field.
Background technology
At present; The anesthetic tube that China uses clinically, material is that PVC or nylon process through extruding mostly, its conduit external diameter is 0.5mm～3.0mm; Internal diameter is 0.2mm～1.8mm; Catheter head is not only thin but also hard, in the human body surgery anesthesia, very easily touches epidural space and produces spasm, will cause puncturing with the conduit misplace when serious and go in the blood vessel.Anesthesia catheter head is softening to be that production firm and doctor are desired always.
The utility model content
The purpose of this utility model is to provide soft anesthetic tube, and it is not only thin but also hard to solve existing anesthesia catheter head effectively, in the human body surgery anesthesia, very easily touches epidural space and produces spasm, will cause puncturing with the conduit misplace when serious and go into the problem in the blood vessel.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme:
Soft anesthetic tube comprises catheter body, it is characterized in that: the head of catheter body is softening section, and the hardness of softening section is less than catheter body.
Preferably, the length of softening section is 2mm～8mm.
Preferably, the external diameter of catheter body is 0.5mm～3.0mm, and internal diameter is 0.2mm～1.8mm.
Preferably, catheter body all adopts PVC to process with softening section.
This utility model has following beneficial effect owing to adopted technique scheme:
Softening section softness of anesthesia catheter head and have elasticity, pliability is controlled, and its hardness is less than catheter body; Use the softening anesthetic tube of handling of head clinically; When inserting human body, its pipe end power that is hampered can change direction voluntarily, guides conduit into the lower resistance gap; Reduce the risk that thorn passes through greatly, increase the security reliability of anesthetic tube.Head significantly softens elastic effect with head without softening having compared of handling through remollescent anesthetic tube, has very high practical value clinically.This utility model is simple in structure, manufacturing is easy, cost is low, practical.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further:
Fig. 1 is the structural representation of soft anesthetic tube of this utility model.
The specific embodiment
As shown in Figure 1, for soft anesthetic tube of this utility model, comprise catheter body 5; Catheter body 5 is provided with infusion hole 1,1cm graduation mark 3,2cm graduation mark 4 and 10cm graduation mark 6, and the head of catheter body 5 is softening section 2, and the hardness of softening section 2 is less than catheter body 5; Catheter body 5 all adopts PVC to process with softening section 2; The external diameter of catheter body 5 is 0.5mm～3.0mm, and internal diameter is 0.2mm～1.8mm, and the length of softening section 2 is 2mm～8mm.Use the softening anesthetic tube of handling of head clinically, when inserting human body, its pipe end power that is hampered can change direction voluntarily, guides conduit into the lower resistance gap, reduces the risk that thorn passes through greatly, increases the security reliability of anesthetic tube.
More than be merely the specific embodiment of this utility model, but the technical characterictic of this utility model is not limited thereto.Any is the basis with this utility model, for realizing essentially identical technique effect, has done the ground simple change, has been equal to replacement or modification etc., all is covered by among the protection domain of this utility model.
