Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described below with reference to the following examples. The examples are intended to illustrate the invention and are not intended to limit the scope of the invention.

As shown in FIG. 1, the present invention comprises: a fixer body which is formed by combining a fixing clamp 1 and a limiting clamp 2,

After the central vein indwelling catheter is connected with a vein (the general puncture position is the neck), the limiting clamp 2 is placed on one side of the indwelling catheter, the catheter fixing area on the limiting block 21 is attached to the side wall of the catheter, the subcutaneous puncture is performed through the limiting needle 22, and then the unilateral fixation is completed through the subcutaneous puncture.

The fixing clip 1 is close to the other side of the indwelling tube, and after the fixing clip is close to the other side of the indwelling tube, the needle ring 12 is sleeved on the top end of the limiting needle 22 to complete fixing.

The limiting block 21 and the center of the fixing block 11 form a catheter fixing area for wrapping and fixing the indwelling catheter.

As the first preferred scheme for fixedly connecting the fixing clip 1 and the limiting clip 2:

as shown in fig. 1-3, the bottom of the limiting block 21 is further provided with an insertion plate, and the shape of the insertion plate corresponds to that of the insertion groove of the fixing block 11.

A limiting groove is formed in the top of the fixer body, the top of the fixing block 11 and the top of the limiting block 21 are spanned, a sliding plate 24 is embedded into the limiting groove in the top of the limiting block 21, and limiting cotton 14 is arranged on the side wall of the limiting groove in the top of the fixing block 11.

The top end of the sliding plate 24 is provided with friction lines.

In the process that the fixing clamp 1 approaches the spacing clamp 2, the fixing block 11 is guided by the embedded plate of the spacing block 21, so that the needle ring 12 is accurately sleeved inside the spacing needle 22.

The cross section of spacing groove is "protruding" font, pushes stopper 21 into the top of fixed block 11 through the finger (generally adopt the thumb), can effectively prevent breaking away from between the two. After the limiting block 21 is pushed in, the limiting cotton 14 is prevented from backing due to external force by friction.

The friction lines at the top end of the sliding plate 24 increase the friction force with the fingers.

As the second preferred scheme of the fixed connection of the fixing clip 1 and the limiting clip 2:

as shown in fig. 4-6, a guide post 26 is fixed on the contact surface of the limit clamp 2 and the fixing clamp 1, and a guide hole 16 corresponding to the guide post 26 is opened on the contact surface of the fixing clamp 1 and the limit clamp 2.

The four guide posts 26 are distributed on four corners of the contact surface of the limiting clamp 2 and the fixing clamp 1.

The guide posts 26 at the four corners and the corresponding guide holes 16 guide the fixing clip 1 and the spacing clip 2 to approach and fix, so as to ensure that the needle ring 12 is accurately sleeved inside the spacing needle 22.

As a supplementary scheme after the device is assembled:

as shown in fig. 7, the outside of the holder body is also pasted with an application.

Thereby reducing the external interference and the dislocation caused by shaking. The application is used as required by existing applications.
