Description

Drainage tube convenient to fix

Technical Field

The application relates to the technical field of medical equipment, in particular to a drainage tube convenient to fix.

Background

The clinical surgical drainage tubes have various types, some are used for catheterization, and some are used for wounds, thoracic cavities, brain cavities, gastrointestinal tracts, biliary tracts and the like. Surgical drainage is used for guiding pus, blood and liquid accumulated in human tissues or body cavities to the outside of a body so as to prevent postoperative infection and influence on wound healing.

The placement of the drainage tube is an important means for surgical observation and treatment, and the fixation of the drainage tube is an important ring for realizing the means. If the drainage tube is not fixed and reliable, the drainage tube can move or be separated, and drainage is influenced or even interrupted.

The drainage tube fixing mode in the prior art is silk suture fixing, a fixing device is firstly additionally arranged, and then the drainage tube is fixed on the skin of a patient in a suture mode, so that the drainage tube is not easy to slide off, and the effect of stable drainage is achieved. It has the following disadvantages: the suture fixation requires more extra prepared instruments, such as: suture lines, suture needles and the like have the disadvantages of inconvenient operation, large workload and low efficiency.

SUMMERY OF THE UTILITY MODEL

An object of this application is to provide a drainage tube convenient to it is fixed inconvenient technical problem to solve among the prior art drainage tube.

The above technical problem of the present application is mainly solved by the following technical solutions:

a drainage tube convenient to fix comprises a drainage tube body, wherein a puncture needle and a retaining ring are arranged in the middle of the drainage tube body and on the outer wall of the drainage tube body, the puncture needle and the retaining ring are arranged at intervals, and the puncture needle can stretch into and penetrate through the retaining ring and is fixedly connected with the retaining ring.

In practical application, after one end of the drainage tube extends into a patient body for drainage, the drainage tube needs to be fixed, the skin on one side of the drainage tube body is pulled up and is slightly higher than the drainage tube, then the puncture needle is used for puncturing and crossing the skin of the patient, the puncture needle tip is exposed, and the buckle ring of the drainage tube body is sleeved on the puncture needle tip to fix the puncture needle tip, so that the effect of fixing the drainage tube is achieved, and the drainage tube can be prevented from moving or dropping off to influence drainage and even interrupt drainage. The application is simple in operation, convenient to use, and need not to prepare instruments such as stylolite, sewing needle, and user's work load is less, and is efficient.

It should be noted that: when a user punctures and crosses the skin of a patient by using the puncture needle, the patient does not feel painful because the patient can be locally anesthetized before the drainage operation.

Connecting portion are cylindrical structure, and the surface of anticreep board is outside bellied arc structure, and wherein the external diameter of connecting portion equals with the external diameter of anticreep board, then has avoided the anticreep board perk, and the scratch patient or user. In addition, the anti-dropping plate and the clamping hook are integrally formed, and the anti-dropping plate and the connecting part are integrally formed, so that the manufacturing is convenient, the installation procedure is saved, and the cost is also saved.

Optionally, the limiting groove is of a circular ring-shaped structure, the limiting groove and the connecting portion are coaxially arranged, and the needle tip portion and the connecting portion are coaxially arranged.

The limiting groove is of an annular structure and is coaxially arranged with the connecting part, so that the inner side wall of the limiting groove can be just positioned in the moving direction of the retaining ring, the movement of the retaining ring is better limited, and the retaining ring is prevented from sliding off the puncture needle. The needle point part and the connecting part are coaxially arranged, so that the needle point part can better lead the connecting part to pass through a hole left by puncture after the needle point part punctures the skin of a patient, and the fixing action of the drainage tube is better completed.

Optionally, the top of needle point portion is overlapped and is equipped with the fixed cover rather than matching, fixed cover with be detachable connection between the needle point portion.

During practical application, after the needle point part finishes puncturing the skin of a patient, the fixed sleeve can be sleeved on the top end of the needle point part, the needle point part can be prevented from stabbing the patient or a user, the retaining ring can be limited to move, the retaining ring is prevented from sliding off from the puncture needle, and therefore the drainage tube is prevented from moving or being separated.

Optionally, the retaining ring and the fixing sleeve are made of silica gel or rubber, and the puncture needle is made of metal.

The retaining ring and the fixing sleeve are made of silica gel or rubber, so that the retaining ring and the fixing sleeve have certain elasticity, and can be connected and fixed with the puncture needle better and more reliably. In addition, the puncture needle is made of metal, so that the puncture effect of the puncture needle is better, the disinfection is convenient, and the infection is prevented.

Optionally, the pjncture needle includes stereoplasm skin and soft inlayer, the outer cover of stereoplasm is established outside the soft inlayer, just the stereoplasm skin with be detachable connection between the soft inlayer.

In practical application, after the puncture needle penetrates through the skin of a patient, the hard outer layer can be taken down, and only the soft inner layer is left, so that the patient can not be stabbed by the soft inner layer. Therefore, the puncture needle punctures the skin of a patient through the hard outer layer and avoids stabbing the patient through the soft inner layer.

Wherein, the hard outer layer can be made of hard materials, and the hard materials can be metals. The soft inner layer can be made of soft materials, and the soft materials can be silica gel, plastic or rubber.

Based on this, this application has fixed convenient, and simple structure, and the preparation is convenient, low cost's advantage than prior art.
