Description

Technical Field

[0001] The utility model relates to the technical field of CVC catheter positioning, in particular to an external CVC catheter fixing device. Background Art

[0002] The CVC catheter is an early rehydration rescue method for patients with severe burn shock. It is mainly inserted through direct skin puncture, through the neck, subclavian and femoral veins, and along the veins to the vena cava. In addition to the function of rehydration, the CVC catheter also has the function of measuring central venous pressure. When in use, the CVC catheter is usually glued to the outer dressing with tape, which is easy to fall off during use. In addition, multiple tapes are required for glueing, and multiple tapes are arranged along the length of the CVC catheter, which makes it extremely inconvenient to adjust the position of the CVC catheter.

[0003] The utility model with the announcement number CN213048665U proposes a CVC catheter fixing device, including a dressing, a base plate and a catheter clamp, wherein the base plate is fixedly arranged on the back of the dressing, the catheter clamp is an annular structure, an opening for clamping the CVC catheter is opened on the catheter clamp, the catheter clamp passes through a connecting shaft facing away from the opening, and the catheter clamp can rotate around the connecting shaft, the connecting shaft is arranged on the base plate, and a stopper is arranged at one end of the connecting shaft away from the base plate to prevent the catheter clamp from falling off; three catheter clamps are arranged on the base plate, and the three catheter clamps are arranged in an equilateral triangle. It can effectively prevent the pulling of gravity and external force and prevent the CVC catheter from falling off.

[0004] However, the above-mentioned prior art still has some shortcomings when used: 1. The positioning method of the patch has the defect of poor convenience in adjusting the installation position, which means that it is inconvenient to change the position of the patch after it is pasted; 2. Three catheter clamps are provided on the patch, and the catheter clamps are in an exposed state, which may easily interfere with the operation of the nursing staff; 3. The positions of the three catheter clamps are fixed, and in order to improve the tightness of the catheter limit, an interference fit is usually used, which makes it inconvenient to adjust the position of the catheter.

[0005] To this end, the utility model provides an external CVC catheter fixing device. Utility Model Content

[0008] Furthermore, two ends of the elastic band are connected by a second Velcro.

[0009] Furthermore, the number of the elastic pressing belts is two and they are arranged along the width direction of the elastic binding belt.

[0010] Furthermore, a silicone strip located between the two elastic pressure belts is bonded to the upper surface of the elastic binding belt.

[0011] Furthermore, the number of the silicone strips is two and arc-shaped pits are arranged along the length direction, and the radius of the arc-shaped pits is smaller than the radius of the CVC catheter.

[0012] Furthermore, the cross-section of the resistance-increasing soft rubber strip is triangular with the small end facing outwards.

[0013] Furthermore, an integrated expansion strip is provided on the top of the resistance-increasing soft rubber strip, and the cross-section of the expansion strip is an arc shape.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides an elastic band to carry components such as an elastic pressure band, a resistance-increasing soft rubber strip, and a silicone strip for fixing the CVC catheter. When in use, the elastic band is wrapped around the arm, thereby facilitating the replacement of the position of the elastic band.

[0016] 2. The utility model provides an elastic pressure belt and arranged and distributed resistance-increasing soft rubber strips, wherein the elastic pressure belt squeezes the CVC catheter into the positioning groove between adjacent resistance-increasing soft rubber strips.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: an external CVC catheter fixing device, including an elastic band 1 and an elastic pressing band 2. When in use, the elastic band 1 and the elastic pressing band 2 both adopt common cloth bands with elastic tightening function. The elastic band 1 is wrapped around the arm when in use. Furthermore, the two ends of the elastic band 1 are connected by a second Velcro 5, which makes the installation and removal of the elastic band 1 more convenient.

[0024] One end of the elastic pressing band 2 is sewn and connected to the upper surface of the elastic binding band 1, and the other end of the back side of the elastic pressing band 2 is connected to the elastic binding band 1 through a first Velcro 3. A plurality of resistance-increasing soft rubber strips 4 are arranged in reverse order along the length on the upper surface of the elastic binding band 1. The resistance-increasing soft rubber strips 4 are opposite to the back side of the elastic pressing band 2. That is to say, when the elastic pressing band 2 is connected to the elastic binding band 1, the elastic pressing band 2 will squeeze and block the resistance-increasing soft rubber strips 4, so that the appearance of the fixing device is in a smooth state.

[0025] The adjacent resistance-increasing soft rubber strips 4 form a positioning groove for limiting the position of the CVC catheter, that is, the CVC catheter will be limited by the adjacent resistance-increasing soft rubber strips 4 and then squeezed and fixed by the elastic pressing belt 2.

[0026] Since the resistance-increasing soft rubber strip 4 is arranged in an array, different positioning slots can be switched by lifting the CVC catheter outward and then sliding it horizontally, which is convenient for adjusting the CVC catheter positioning and fixing position according to the patient's body position. Among them, the cross-section of the resistance-increasing soft rubber strip 4 is triangular and the small end faces outward. This arrangement facilitates the lateral sliding of the CVC catheter, and an integrated expansion strip 41 is arranged on the top of the resistance-increasing soft rubber strip 4. The cross-section of the expansion strip 41 is arc-shaped. The expansion strip 41 plays a role in limiting the CVC catheter to prevent it from being accidentally pulled sideways and causing displacement.

[0027] In this embodiment, there are two elastic pressure belts 2 and they are arranged along the width direction of the elastic binding band 1. There are gaps between adjacent elastic pressure belts 2. This arrangement can improve the reliability of positioning and fixing the CVC catheter.

[0028] Furthermore, a silicone strip 6 located between the two elastic pressure strips 2 is bonded to the upper surface of the elastic band 1. After the CVC catheter is positioned and fixed, it will squeeze the silicone strip 6. The function of the silicone strip 6 is to increase the resistance between the CVC catheter and the elastic band 1, and play a role in preventing slipping. Preferably, there are two silicone strips 6 and arc-shaped pits 61 arranged along the length direction are formed thereon. The radius of the arc-shaped pit 61 is smaller than the radius of the CVC catheter. When in use, the CVC catheter is squeezed in the arc-shaped pit 61.

[0029] When using this device, first tie the elastic strap 1 to the patient's arm through the first Velcro 3 at the head and tail, then put the CVC catheter into the position between the adjacent resistance-increasing soft rubber strips 4, and connect the elastic pressure belt 2 to the outer surface of the elastic strap 1 through the second Velcro 5. At this time, the elastic pressure belt 2 will squeeze the CVC catheter between the adjacent resistance-increasing soft rubber strips 4, and the CVC catheter will also squeeze the silicone strip 6. Finally, hold the CVC catheter and slide it horizontally to switch the position. After switching, it will be limited by the adjacent resistance-increasing soft rubber strips 4 in different positions.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
