Description

Anesthesia catheter fixer

Technical Field

The utility model relates to an anesthesia catheter fixer.

Background

When clinically performing epidural anesthesia, a channel is generally established through an epidural puncture needle to reach an epidural space, an anesthetic is injected immediately, then an epidural anesthesia catheter is placed through an inner cavity of the epidural needle, the anesthetic is dispersed through a drug outlet hole at the head end of the epidural catheter, nerves in a target area are blocked, and an analgesic effect is achieved; in the traditional puncture mode, after the catheter enters an epidural space, the epidural needle is withdrawn, and the catheter can be used for continuous administration in operation or continuous analgesia after operation; because of epidural puncture needle diameter is greater than epidural anesthesia pipe, after epidural needle withdraws from the human body, its itself can't be closed at the wound that the puncture site caused, when the in-process of injecting or postoperative pump into anaesthetic through anesthesia pipe, anaesthetic just can pass through this wound seepage, causes anesthesia effect not good, anesthesia pipe is less than the wound because of its diameter, though human tissue elasticity can have certain tightening up to it, still can lead to anesthesia pipe to take place to shift or drop because of anaesthetic infiltration.

The traditional mode for solving the problem of anesthetic permeation is that after the epidural puncture needle is withdrawn, some absorbable gel is filled around the anesthetic catheter in a circle at the wound part to block the anesthetic permeation, meanwhile, the anesthetic catheter is fixed with certain help, and then the anesthetic catheter at the wound is pasted on the skin by a sticker to prevent leakage. The method has two disadvantages, namely, the cost of the biological gel is high, the cost of a patient is increased, the biological gel is not beneficial to popularization, and the anesthetic catheter is fixed on the skin through the adhesive, so that the catheter is easy to be broken, and the drug flow rate of the catheter is influenced; when the body position of a patient is moved, the catheter is pulled to easily cause the falling of the catheter, and the operation effect is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anesthesia catheter fixer utilizes the extrusion to draw in the stand for the clearance between the stand diminishes, thereby can the fixed anesthesia catheter of centre gripping.

The above technical purpose of the present invention can be achieved by the following technical solutions:

an anesthesia catheter fixer comprises a base, wherein a patch for adhering epidermis is fixed at the bottom of the base, an insertion hole is formed in the base and the patch in a penetrating mode, the base comprises at least 3 elastic stand columns, the stand columns deviate from an adhesion surface of the patch, the stand columns are arranged around the insertion hole, and a gap for inserting an anesthesia catheter is formed between every two adjacent stand columns;

the base can be dismantled and be connected with the block of cover establishing the stand top, and the top of stand is equipped with the inclined plane, and the block inner wall is equipped with the pressfitting piece, and the pressfitting piece supports to press the inclined plane to drive the stand to press from both sides tightly towards the picture peg hole each other thereby realize anesthesia pipe location centre gripping in the clearance.

Through adopting above-mentioned technical scheme, reserve tube hole also can supply the anesthesia pipe to stretch out, because reserve tube hole also puts at the central point that the stand centers on, reserve tube hole and tube inserting hole's concentricity is higher, and crooked radian is less when the anesthesia pipe stretches out from reserve tube hole, and the later stage circulates more smoothly when pouring into anesthetic liquid in the anesthesia pipe.

Preferably, the border of stand is equipped with the card shoulder, and the inner wall of block is equipped with the snap ring, and snap ring block card shoulder is in order to realize the fixed of block and stand.

Through adopting above-mentioned technical scheme, the division of block and stand of being convenient for is more convenient to operate more with the card shoulder block relation.

Preferably, the inner wall of the cap and the outer wall of the upright post are fixed by screw threads.

Through adopting above-mentioned technical scheme, threaded connection makes the connection of block and stand more firm.

Preferably, the pressing piece is an inclined pressing surface, and the inclined pressing surface is abutted to the inclined surface.

By adopting the technical scheme, the inclined pressing surface is pressed against the inclined surface, so that the stand columns are accommodated mutually.

Preferably, the pressing piece is a pressing ring, and the inner edge of the pressing ring is abutted to the inclined plane.

By adopting the technical scheme, the pressing ring is pressed against the inclined plane, so that the stand columns are accommodated mutually.

Preferably, the adhesive side of the patch is coated with a plastic film.

By adopting the technical scheme, the plastic film has poor viscosity and can be quickly separated from the patch.

Preferably, the number of the pillars is 4.

Through adopting above-mentioned technical scheme, the quantity of stand is that 4 are comparatively excellent.

To sum up, the utility model discloses following beneficial effect has: the fixer of this scheme can prevent the weeping, can let the anesthesia catheter stable fixation on skin again, and can prevent to discount.
