Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical auxiliary instrument, and relates to central vein U type catheter external fixing device. BACKGROUND

[0002] Vicryl is a new type of fixing device that has been used in China in recent years, Vicryl follows the seamless and fixed recommendations recommended by OSHA, provides a clinical solution for catheter fixation, and is commonly used for fixing the catheter connected in the body.

[0003] The currently used Vicryl is generally only used for the external fixation of picc catheter, and cannot achieve U type fixation. For example, the exposed part of the internal jugular vein catheter and the subclavian vein catheter is long, and since there is no fixing device, only the suture fixation on the skin of the patient during the catheter placement by the doctor, the comfort of the patient is increased, and in addition, the sutured part needs to be removed in the later catheter removal, which increases the pain of the patient and the risk of skin infection. In addition, the U type fixation of the catheter can reduce the risk of catheter prolapse, and the nurses cannot achieve proper fixation when performing U type fixation due to the influence of multiple factors such as technology and skin around the catheter of the patient.

[0004] At the same time, for some special patients, such as obese patients, patients with many wrinkles on the neck, and male patients with many beards, the venous catheter adhesive film cannot be closely attached, which easily causes the edge of the adhesive film to be rolled, the catheter to be folded, and the U type fixation of the catheter to be incomplete, and the catheter is easily prolapsed when the patient moves, sweats, or changes clothes; in addition, when the catheter is folded, it also causes the infusion to be not smooth, thereby leading to the treatment effect not being in place.

[0024] Please see Figs. 1-2 As shown in the drawings, the device mainly provides a central venous U-shaped catheter external fixation device to facilitate the external fixation of the central venous catheter, skin protection, increase patient comfort, facilitate patient activity, and ensure the effectiveness of treatment; based on this, the device comprises a fixing patch 1 and a buckle group 2, wherein the fixing patch 1 is used to be fixed on the skin of the patient; and the fixing patch 1 is made of medical breathable fabric, and a sticky layer 3 is arranged on the bottom surface of the fixing patch, and a release paper 4 is arranged on the sticky layer 3; when fixing the fixing patch 1, the release paper 4 can be torn to expose the sticky layer on the bottom surface of the fixing patch, and it is fixed on the skin of the patient; and in order to facilitate better and faster tearing of the release paper, a fixing ear for assisting tearing can be arranged at one end of the release paper, thereby improving the fixing efficiency of medical staff; in addition, the breathability of the fixing patch 1 can also reduce the occurrence of pressure sores, allergies, swelling and other conditions caused by long-term sticking on the skin of the patient, and improve the comfort of use.

[0025] In this embodiment, the fixing patch 1 comprises a U-shaped fixing patch 11 and an arc-shaped fixing patch 12 connected in one piece; wherein the connection part of the U-shaped fixing patch 11 and the arc-shaped fixing patch 12 is also provided with a tearable line 13, and the tearable line 13 can be matched and divided according to the different exposed lengths of the catheter, the different skin of the puncture site, and the different sizes of the fixable range. Specifically, because the device is fixed from the catheter to the skin outlet, one or more fixing settings can be made according to the different conditions of the patient during fixing, and because the exposed length of the catheter is different, the skin of the puncture site, the size of the fixable range, and the different curvature of the catheter that needs to be shaped, such as shaped as a large U or a small U, the tearable end can be torn according to the situation to tear off one of the U-shaped fixing patch or the arc-shaped fixing patch (such as children can use the upper fixing buckle and tear off the lower one), thereby meeting the use of different patients, improving the comfort and diversity of use.

[0026] In this embodiment, the whole fixing patch 1 before being torn is in the shape of a water droplet, which is thin on the top and wide on the bottom, and because the water droplet shape is relatively round, it is more beneficial to protect the skin and improve comfort, and the U-shaped curvature 6 arranged in the middle can help manual shaping during use to prevent wrinkles and skin pressure injuries caused by sticking.

[0027] In the embodiment, the buckle groups 2 are fixedly arranged at two ends of the fixing patch 1 respectively, and are used for clamping the catheter; the buckle groups 2 are each composed of two mutually symmetrical buckles, wherein the buckle groups include a first buckle group 21 and a second buckle group 22, the first buckle group 21 is arranged at the two ends of the U-shaped fixing patch respectively; the second buckle group 22 is arranged at the tail end of the arc-shaped fixing patch, and is used for clamping the catheter end extending downwards from the skin outlet; when fixing the catheter, according to different conditions of patients, fixing on the U-shaped fixing patch (the arc-shaped fixing patch is torn off through the tearable line, and the first buckle group at the two ends of the U-shaped fixing patch is used for fixing the catheter, and the catheter between the two points can naturally form a U shape, so as to prevent the catheter from being pulled out and the exposed end from being folded) or integral fixing (the first buckle group at the head end of the U-shaped fixing patch and the second buckle group at the tail end of the arc-shaped fixing patch are used for head-tail fixing, and the catheter between the two points can also naturally form a U shape, so as to prevent the catheter from being pulled out and the exposed end from being folded) can be performed.

[0028] In the embodiment, the fixing patch 1 is further provided with a U-shaped small groove 5 at the end in contact with the skin outlet, and the U-shaped small groove 5 is used for fixing the catheter at the skin outlet in cooperation with the buckle group.

[0029] It should be noted that: when in use, the fixing patch with the buckle group is first attached to the skin of the patient, and the catheter is fixed on the buckle group of the fixing patch, and after the fixing is completed, a layer of transparent patch film can be attached to the catheter according to the fixed condition, so as to play a double fixing role, prevent the catheter from slipping off and folding, and improve the stability during use; in addition, the fixing patch material in the device is soft and has certain air permeability, which can improve the comfort of the patient in use; and the special structure of the fixing patch can make the catheter between the two points naturally form a U shape, prevent the catheter from being pulled out and the exposed end from being folded, ensure the smoothness of the infusion, and improve the treatment effect.
