Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, the present utility model provides a technical solution for a drainage catheter holder:

the utility model provides a drainage catheter fixer, includes self-adhesive tape 1, and self-adhesive tape 1's size is 12.5.5 and is 9.5 centimetres, and self-adhesive tape 1 of this size is attached on skin surface comparatively suitable, can provide sufficient adhesion, can prevent again that self-adhesive tape 1 that skin folding appears when self-adhesive tape 1 area is too big from droing. In order to improve the attaching durability of the self-adhesive tape 1, a water absorbing paper 2 is arranged on the adhesive surface of the self-adhesive tape 1, and the water absorbing paper 2 is used for absorbing a small amount of sweat on the skin surface. The adhesive surface of the self-adhesive sticker 1 is provided with a fixed base 3, a cylindrical cavity 4 is arranged inside the base 3, an opening 5 is arranged at the top of the base 3, and a base guide pipe inlet 6 and a base guide pipe outlet 7 are arranged on the side wall of the base 3. The central position of the base catheter inlet 6 and the central position of the base catheter outlet 7 are positioned on the same axis, and the arrangement ensures that the drainage catheter can not bend when passing through the fixer, thereby improving the passing efficiency of the drainage catheter. Inside the cylindrical cavity 4 there is provided a return spring 8 and a clamping button 9, the clamping button 9 comprising a button head 10 and a button belly 11. The button head 10 has a smaller diameter than the opening 5 and the button belly 11 has a larger diameter than the opening 5. The return spring 8 abuts against the button belly 11, and the button head 10 is pushed out of the opening 5 by the elastic force of the return spring 8, so that the button belly 11 is retained in the cylindrical cavity 4. In order to prevent the clamping button 9 from shaking greatly, the sizes of the cylindrical cavity 4 and the button belly 11 are limited, the height of the cylindrical cavity 4 is 2.0 cm, the diameter of the cylindrical cavity is 3.0 cm, the button belly 11 is cylindrical, the height of the button belly 11 is 1.0 cm, the diameter of the button belly 11 is slightly smaller than the diameter of the cylindrical cavity 4, a movable gap is reserved between the button belly 11 and the cylindrical cavity 4, and the button belly 11 can be ensured to move up and down. The catheter channel 12 is arranged on the abdomen 11 of the button, the axis of the catheter channel 12 coincides with the axes of the base catheter inlet 6 and the base catheter outlet 7, the cross section shape and the dimension of the catheter channel 12 are the same as those of the base catheter inlet 6 and the base catheter outlet 7, and the arrangement is also used for ensuring that the drainage catheter can smoothly pass through. In order to prevent dislocation of the duct channel 12, the base duct inlet 6 and the base duct outlet 7, a limit bar 13 is arranged on the outer side wall of the button head 10, a limit recess 14 is correspondingly arranged on the inner side wall of the opening 5, and the limit bar 13 is matched with the limit recess 14, so that the clamping button 9 can be prevented from rotating. In order to strengthen the drainage catheter bundle in the catheter channel 12, two stop piles 15 are arranged in the catheter channel 12.

In the use process, the release paper with the adhesive surface is removed, and the fixer is attached near the wound. Pressing the clamp button 9 compresses the return spring 8, and the clamp button 9 retracts into the base 3. When the drainage catheter reaches the lowest position, the catheter channel 12, the base catheter inlet 6 and the base catheter outlet 7 are aligned, the opening of the fixer is completely opened, and an operator sequentially passes the drainage catheter through the base catheter inlet 6, the catheter channel 12 and the base catheter outlet 7. The pressure on the clamping button 9 is removed, the return spring 8 rebounds, dislocation occurs among the base catheter inlet 6, the catheter channel 12 and the base catheter outlet 7, and the drainage catheter is clamped. The size of dislocation is changed according to the change of the deformation degree of the spring, so that the device can adapt to the clamping of drainage catheters with different diameter sizes.

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