Description

Epidural catheter adapter

Technical Field

The utility model relates to a medical appliance, in particular to an epidural catheter adapter.

Background

Most of the currently used epidural catheter injection end holders are screw-threaded, and as shown in fig. 1, include a first engagement portion 100', a second engagement portion 200', and a stopper 300'. Wherein a first end of the first engagement portion 100 'engages the epidural catheter and a second end engages a first end of the second engagement portion 200'; the second end of the second connecting part is connected with the plug. A rubber sleeve 400' is disposed in the second end of the first engagement portion, and when the second end of the first engagement portion 100' engages with the first end of the second engagement portion 200', the first end of the second engagement portion 200' presses the rubber sleeve 400', which seals on the one hand, and clamps and secures the epidural catheter on the other hand.

In the prior art, the core is often focused on the fixation of the epidural catheter to the human body, and the fixation between the epidural catheter and the adapter is neglected.

In fact, existing structures such as that shown in fig. 1 tend to come loose in some scenarios. If the labor and pain relieving time can be longer than 20 hours, the puerpera often needs to turn over for movement, even get up for movement, and the connector frequently falls off clinically, so that the medicine outflow is caused, the pain relieving effect is influenced, and even accidents cause risks for the puerpera.

Some medical staff often wrap the engagement of the holder with the catheter with adhesive tape during clinical work to prevent the catheter from falling off. However, the method needs to design the size, width and shape of the rubberized fabric by itself, thus greatly delaying time and reducing clinical work efficiency.

Examples

Referring to fig. 2, the present utility model discloses an epidural catheter adapter, which comprises a first adapter part 100, a second adapter part 200, a plug 300 and an adhesive part 400.

For ease of understanding and description, the present utility model defines the left side of each component in each figure as a first end and the right side of each component as a second end.

Then, the first end of the first engaging portion 100 engages with the epidural catheter 500, and the second end engages with the first end of the second engaging portion 200; the second end of the second engagement portion 200 engages the plug 300. The first end of the adhesive part 400 forms a semicircular groove 410 adapted to the diameter of the epidural catheter 500, an adhesive layer 420 is provided in the semicircular groove 410, and the second end of the adhesive part 400 engages with the first end of the first engaging part 100.

In this way, the first end of the adhesive part 400 forms the semicircular groove 410 adapted to the diameter of the epidural catheter 500, the adhesive layer 420 is disposed in the semicircular groove 410, and the epidural catheter 500 can be adhered by the adhesive layer 420, so that the epidural catheter 500 is effectively prevented from falling off.

It is easy to understand that the adhesive layer may be a double sided adhesive, one side of which is adhered in the semicircular groove 410, and the other side of which is adhered with non-stick paper, and the adhesive layer is just uncovered for use.

It should be noted that, in the present utility model, the second end of the adhesive portion 400 is connected to the first end of the first connecting portion 100 in an integral manner (in this case, the adhesive portion 400 and the first connecting portion 100 are combined into a whole, as shown in fig. 6); the connection mode can also be split type, as shown in fig. 2, the split type has the advantages that: on the one hand, the first engagement portion 100 of the existing hard film adapter can be reformed, or the mold thereof can be reformed, so that the waste of the original materials is reduced to a certain extent, and on the other hand, a foundation is laid for the reinforced clamping structure.

In a preferred embodiment, the top opening of the semicircular groove 410 is smaller than the diameter of the catheter of the epidural catheter 500. In this way, radial constraint can be formed on the epidural catheter 500, so that the epidural catheter 500 is prevented from being lifted from the semicircular groove 410 due to dragging, and the bonding adhesive layer 420 is matched, so that the bonding effect is better, and the requirements of dragging in most scenes can be met. On the other hand, the edge of the adhesive layer 420 may be blocked by the top opening, avoiding pressing into the epidural catheter 500,

in a preferred embodiment, the first end of the first engagement portion 100 forms a threaded hole 110 coaxial with the conduit through hole thereof, and the second end of the adhesive portion 400 forms a stud 430 coaxial with the conduit through hole thereof, and the stud 430 is screwed into the threaded hole 110.

In addition, the hole bottom of the threaded hole 110 at the first end of the first connecting portion 100 forms a coaxial taper hole, the second end of the bonding portion 400 forms a taper post 440 coaxial with the stud 430 thereof, and the taper post 440 is provided with a plurality of deformation grooves 441 along the radial direction thereof; when the tapered column 440 is tightly pressed in the tapered hole, the tapered column 440 is radially pressed to hoop the epidural catheter 500.

Further, the tapered post 440 may further be inwardly protruded at an edge of the conduit through hole thereof to form a jaw 442, a first end of the jaw 442 linearly transitions with the conduit through hole thereof, and a second end of the jaw 442 is flush with the second end of the tapered post 440. The epidural catheter 500 is reliably clamped by the hoop action of the claws 442, and the possibility of loosening is basically eliminated.

In this embodiment, in order to facilitate the connection of the adhesive portion 400 with the first engaging portion 100, the adhesive portion 400 is radially formed with a butterfly handle 450 for manual rotation.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
