Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to a medical catheter fixing patch. Background Art

[0002] In clinical medical and nursing work, various catheters are needed, such as trachea, drainage tubes, infusion tubes, etc. These catheters generally need to be fixed when in use to prevent them from being displaced. Catheter dislocation will cause certain inconvenience to patients and sometimes increase their pain. Severe dislocation may also lead to medical accidents.

[0003] The patent with patent number 202123066526.4 discloses a new type of catheter fixing patch, including a fixing patch, a fixing tube, and a reinforcement belt. The back of the fixing patch is an adhesive layer, the fixing tube is fixed to the middle of the upper surface of the fixing patch, and the two ends of the fixing tube extend out of the upper and lower ends of the fixing patch. Strip belts are provided on both sides of the fixing tube, and the strip belts are fixed to the middle of the upper surface of the fixing patch. The strip belts are provided with a number of positioning grooves. The front end of the fixing tube is provided with a strip hole that passes through the upper and lower parts. The cross-section of the reinforcement belt is Ω-shaped, and positioning blocks matching the positioning grooves are provided at the bottom of both sides of the reinforcement belt. The fixing tube and the reinforcement belt are made of plastic or rubber. The utility model has a novel structure. The fixing tube is added to wrap the pipeline, so that the catheter can be easily fixed to the body, and the fixation is more secure and not affected by dust and seepage; and the fixing tube is supportive and can prevent the pipeline from folding.

[0004] The above-mentioned catheter fixing patch has the following disadvantages: due to the different functions of the catheters, their diameters are different. After the catheter is placed inside the fixing tube and the reinforcement belt is installed, the catheter can still move relative to the fixing patch, and effective fixation cannot be performed. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end, one purpose of the utility model is to provide a medical catheter fixing patch.

[0006] A medical catheter fixing patch according to the utility model comprises an adhesive patch and a fixing component arranged on the surface of the adhesive patch, wherein an adhesive layer is arranged on the lower surface of the adhesive patch, and the fixing component is composed of a fixing seat, and the fixing seat is fixedly connected to the upper surface of the adhesive patch, a fixing groove with a circular cross-section is provided in the middle of the fixing seat, and an opening connected to the fixing groove is provided at the upper end of the fixing seat, a plurality of airbag tubes are evenly distributed on the inner wall of the fixing groove of the fixing seat, an installation cavity is provided inside the lower end of the fixing seat, an adjustment mechanism is provided in the installation cavity, and the adjustment mechanism is connected to the airbag tube through an air guide tube.

[0007] Preferably, the adjustment mechanism includes a screw rod, a guide rod, a sleeve and a piston column. The screw rod and the guide rod are arranged in the installation cavity along the length direction of the fixed seat and are arranged parallel to each other. A movable plate is arranged on the outer side of one end of the screw rod and the guide rod. The sleeve is arranged between the screw rod and the guide rod and is fixedly connected to the inner wall of the installation cavity through a connecting rod. One end of the piston column is located inside the sleeve, and the other end is fixedly connected to the side of the movable plate.

[0009] Preferably, one end of the air guide tube is connected to the interior of the sleeve.

[0010] Preferably, the outer surface of the airbag tube is provided with anti-slip patterns.

[0011] Preferably, a peelable release paper is provided on the lower surface of the adhesive layer.

[0012] The beneficial effects of the utility model are:

[0013] 1. A fixing groove is provided inside the fixing seat, an airbag tube is arranged on the inner wall of the fixing groove, and an adjusting mechanism connected with the airbag tube is combined. During use, after the catheter is placed in the fixing groove, the movable plate and the piston column are driven to move synchronously by rotating the screw rod, and the air in the sleeve is pressed into the inside of the airbag tube, so that the airbag tube expands and is in close contact with the catheter, so that it can be suitable for fixing catheters of different diameters. The structure is simple, practical, convenient and fast.

[0014] 2. Anti-skid patterns are arranged on the outer surface of the airbag tube, and the anti-skid patterns are formed by multiple vertical patterns and horizontal patterns arranged at intervals. When the airbag tube is inflated, the anti-skid patterns are in close contact with the surface of the catheter, which can not only prevent the catheter from falling off, but also prevent the fixing seat and the catheter from relative movement, thereby further enhancing the stability of the connection with the catheter.

DETAILED DESCRIPTION

[0020] Reference Figure 1-4 A medical catheter fixing patch comprises an adhesive patch 1 and a fixing component arranged on the surface of the adhesive patch 1, wherein an adhesive layer 2 is arranged on the lower surface of the adhesive patch 1, and the fixing component is composed of a fixing seat 3, and the fixing seat 3 is fixedly connected to the upper surface of the adhesive patch 1, and a fixing groove 4 with a circular cross-section is opened in the middle of the fixing seat 3, and an opening 5 connected to the fixing groove 4 is opened at the upper end of the fixing seat 3, and a plurality of airbag tubes 6 are evenly arranged on the inner wall of the fixing groove 4 of the fixing seat 3, and an installation cavity 7 is opened inside the lower end of the fixing seat 3, and an adjustment mechanism is arranged in the installation cavity 7, and the adjustment mechanism is connected to the airbag tube 6 through an air guide tube 8.

[0021] The adjustment mechanism includes a screw rod 9, a guide rod 10, a sleeve 11, and a piston column 12. The screw rod 9 and the guide rod 10 are arranged in the installation cavity 7 along the length direction of the fixed seat 3 and are arranged parallel to each other. A movable plate 13 is arranged on the outer side of one end of the screw rod 9 and the guide rod 10. The sleeve 11 is arranged between the screw rod 9 and the guide rod 10, and is fixedly connected to the inner wall of the installation cavity 7 through a connecting rod 14. One end of the piston column 12 is inside the sleeve 11, and the other end is fixedly connected to the side of the movable plate 13.

[0022] Both ends of the guide rod 10 are fixedly connected to the interior of the installation cavity 7 , one end of the screw rod 9 is rotatably connected to the inner wall of the installation cavity 7 , and the other end of the screw rod 9 extends to the outside of the fixing seat 3 .
