Description

Ultra-smooth elastomer catheter for medical instrument

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a super-smooth elastomer catheter for medical equipment.

Background

The medical catheter is a tubular product for medical treatment and can be divided into two types of external use and internal use, wherein the medical catheter is used for conveying various gases and liquids, such as a stethoscope rubber tube and an infusion rubber tube, and is a common medical tool in the field of human intervention;

however, the existing catheters are too long in length and are easy to be wound and knotted in the actual use process, and therefore, a super-smooth elastomer catheter for medical instruments is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a super-smooth elastomer pipe for medical instrument to the length that proposes current pipe among the above-mentioned background art often can the overlength, and can twine the problem of knoing easily in the in-service use.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a super smooth elastomer pipe for medical instrument, includes the skin, the outside in the outside can be dismantled and be connected with the magnet ring, the inner wall fixedly connected with protective ring of magnet ring, protective ring cup joints in the outer outside, outer inboard is provided with the weaving layer, the inboard of weaving layer is provided with the inlayer, outer outside is provided with the lubricant film.

Preferably, the outer layer is an outer layer made of a polyether amino block copolymer resin.

Preferably, the inner layer is made of polytetrafluoroethylene.

Preferably, the braided layer is formed by spirally winding silk threads to form a braided rope and then cross-braiding the braided rope.

Preferably, the number of the magnet rings is provided with a plurality of groups.

Preferably, the lubricating layer is made of silicon-based lubricant.

Compared with the prior art, the beneficial effects of the utility model are that: this a super smooth elastomer pipe for medical instrument is through being provided with the multiunit magnet ring, when super smooth elastomer pipe is using too long duration, can make a plurality of magnet ring adsorbs together with super smooth elastomer pipe winding circle to made things convenient for and accomodate the winding to super smooth elastomer pipe, fine avoided super smooth elastomer pipe overlength and the problem of knoing, improved the result of use and the practicality of super smooth elastomer pipe.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a super smooth elastomer pipe for medical instrument, including outer 1, outer 1 is the skin that polyether amino block copolymer resin made, the compliance and the chemical substance tolerance of pipe have been improved, reduce the resistance of pipe in blood simultaneously, the outside of outside 1 can be dismantled and be connected with magnet ring 2, the quantity of magnet ring 2 is provided with the multiunit, be convenient for carry out magnetism to the pipe and inhale fixedly, the inner wall fixedly connected with of magnet ring 2 protects packing ring 5, protection packing ring 5 cup joints in the outside of outer 1, the inboard of outer 1 is provided with weaving layer 3, weaving layer 3 is formed by alternately weaving behind the spiral winding formation strand of braided rope of silk thread, increase radial and axial intensity and pliability of pipe, the inboard of weaving layer 3 is provided with inlayer 4, inlayer 4 is the inlayer that polytetrafluoroethylene made, make the pipe have good chemical stability, corrosion resistance, The catheter has the advantages that the catheter is high in sealing performance, lubrication non-stick performance and biocompatibility, the lubricating layer 6 is arranged on the outer side of the outer layer 1, the lubricating layer 6 is made of silicon-based lubricating agents, and the lubricating performance of the catheter is improved.

The working principle is as follows: through being provided with multiunit magnet ring 2, when the super-smooth elastomer pipe is using too long duration, can make a plurality of magnet rings 2 adsorb together with super-smooth elastomer pipe wound circle to made things convenient for and accomodate the winding to super-smooth elastomer pipe, fine avoided super-smooth elastomer pipe overlength and the problem of knoing, improved the result of use and the practicality of super-smooth elastomer pipe.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
