Abstract
The utility model discloses a central venous catheter external member, which comprises a central venous catheter, a skin expanding needle, a puncture needle, a guide wire and a sleeve sleeved on the central venous catheter, wherein one end of the sleeve is provided with a plurality of fixed side wings which are tightly attached to the skin surface of a patient, and a plurality of suture holes are arranged on the fixed side wings; the utility model discloses simple structure, fixed firm, convenient operation, with low costs, in clinical in-service operation use, solve because of the subcutaneous tissue is loose relatively on every side, central ductus venosus is located subcutaneous position and rolls over easily, is difficult to guarantee unobstructed problem, and then reduces the medical risk, can also alleviate medical personnel's nurse vigor simultaneously, suitable to clinical popularization.
Description
Technical Field
The utility model relates to a medical equipment's technical field, more specifically the utility model relates to a central venous catheter external member that says so.
Background
In the clinical actual operation use, often take place central venous catheter and turn over the phenomenon, lead to the pipe can't maintain infusion passageway or the drainage unobstructed, because of subcutaneous surrounding tissue is loose relatively, the position is most located subcutaneously to the pipe position of turning over, this greatly increased medical risk, delay or aggravate the patient's condition even.
In the prior art, the related anti-folding central venous catheter mainly utilizes a spring guide wire to wind the catheter, plays a certain spring role to prevent the catheter from being folded, and the guide wire and the catheter are required to be placed into a patient together by the technology, so that if the patient is restless repeatedly or the body position is changed, the spring guide wire is easy to deform and draw, and the smoothness of the central venous catheter cannot be ensured.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned technical problem and provide a central venous catheter external member.
The utility model discloses a following technical scheme realizes: the utility model provides a central venous catheter external member, includes central venous catheter, expands skin needle, pjncture needle and seal wire, still establishes the sleeve pipe on central venous catheter including the cover, the sleeve pipe adopt to have anti deformation's plastic pipe to make, the sleeve pipe long 2cm, sheathed tube pipe diameter is greater than central venous catheter's pipe diameter, sheathed tube one end has a plurality of fixed flanks of hugging closely patient skin surface, and is a plurality of fixed flanks on all have a plurality of suture holes, the sleeve pipe is kept away from the one end of fixed flank and is arc.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
the utility model discloses simple structure, fixed firm, convenient operation, with low costs, in clinical in-service operation use, solve because of the subcutaneous tissue is loose relatively on every side, central ductus venosus is located subcutaneous position and rolls over easily, is difficult to guarantee unobstructed problem, and then reduces the medical risk, can also alleviate medical personnel's nurse vigor simultaneously, suitable to clinical popularization.
Drawings
The accompanying drawings, which are included to provide a further understanding of the embodiments of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention.
Fig. 1 is a schematic structural view of a central venous catheter kit according to the present invention.
Description of reference numerals:
1. central venous catheter, 2, sleeve, 21, fixed side wing, 22, suture hole.
Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.
As shown in figure 1, the central venous catheter kit comprises a central venous catheter 1, a skin expanding needle, a puncture needle, a guide wire and a sleeve 2 sleeved on the central venous catheter 1, wherein one end of the sleeve 2 is provided with a plurality of fixed side wings 21 attached to the skin surface of a patient, and a plurality of suture holes 22 are formed in the plurality of fixed side wings 21.
In the clinical practical operation and use process, after a puncture needle is punctured to a target blood vessel or a pleural and peritoneal water level, a guide wire is placed, a skin expanding needle penetrates through skin and muscle along a puncture point of the puncture needle to reach the puncture position and then is pulled out, a sleeve 2 is sleeved on the guide wire at the moment and is placed under the skin along the guide wire through a puncture hole, a fixed side wing 21 on the sleeve 2 is exposed and clings to the skin, then a central venous catheter 1 penetrates through the sleeve 2 along the guide wire and is placed into the blood vessel or reaches the pleural and peritoneal cavity tube placement position, the guide wire is pulled out, finally the fixed side wing 21 is fixed on the surface of the skin through a suture hole 22 in a suture mode, and the sleeve 2 which is placed in the puncture hole and is used for the central venous catheter 1 to pass through is used for avoiding the phenomenon that the part of the central venous catheter 1 under the skin is easy to break, so as to ensure that the central venous catheter 1 is smooth.
As a preferable scheme of the above embodiment, the length of the cannula 2 is 2cm, so that the cannula 2 is injected into the subcutaneous part for 2cm, and the pipe diameter of the cannula 2 is larger than that of the central venous catheter 1, so that the central venous catheter 1 can also pass through the cannula 2 after a guide wire passes through the cannula 2.
In a preferred embodiment of the above embodiment, the end of the sleeve 2 away from the fixed wing 21 is arc-shaped, so that the friction between the end edge of the sleeve 2 and the periphery of the puncture hole is reduced in the process of inserting the sleeve 2 into the puncture hole.
As a preferable solution of the above embodiment, the sleeve 2 is made of a plastic tube with deformation resistance.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
Claims (4)
