Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical apparatus and instruments, and particularly relates to an easy-to-tear damage-preventing multifunctional indwelling needle patch. BACKGROUND

[0002] Enhanced CT, also known as contrast-enhanced CT, is a method for improving the diagnostic accuracy by injecting contrast medium into a suspected part through an indwelling needle and then performing CT scanning again after CT scanning. The contrast medium used in enhanced CT is a chemical product injected into human tissues or organs to enhance image observation. According to relevant industry standards, the injection speed of contrast medium can reach 3-4 ml / s. In contrast, the injection speed of ordinary intravenous injection is usually only 0.05-0.25 ml / s. Under such high injection speed, even if the indwelling needle has been adhered to the skin by the patch, the indwelling needle is still very easy to come out of the blood vessel under the huge injection pressure.

[0003] The existing indwelling needle patch has a one-piece structure and cannot cover the main body end of the indwelling needle, so the adhesion is relatively weak and is only suitable for ordinary intravenous injection with relatively low injection speed. During the process of pulling out the indwelling needle, the patch is difficult to tear off and is easy to tear the skin, and the operation is also more troublesome. Therefore, a new technology needs to be designed to improve this phenomenon. UTILITY MODEL CONTENT

[0017] The utility model will be further described in detail below in connection with the drawings and embodiments.

[0018] As Figures 1 to 5 Indicated, a kind of easy tear and prevent damage multifunctional indwelling needle application, including application layer 1;The application layer 1 overall is T type, and the gauze cotton 4 is arranged in the center of the web 1a of the application layer 1;The lower portion of the web 1a of the T type application layer 1 and lower portion are equipped with T type line, and the T type line is symmetrical about the gauze cotton 4;The two side flanges 1b of the T type application layer 1 are equipped with horizontal straight line respectively;The lower layer of the application layer 1 is equipped with protective layer film;Above setting medical staff can quickly tear open arc-shaped tear opening 2c with one hand, and the application fixed indwelling needle is adhered to skin and is flattened in turn to make it flat;Flange 1b can be used to fixed medicine end 3d or flow stopper 3c.

[0019] This invention utilizes a T-shaped structure to fix the main end of the indwelling needle, ensuring that the indwelling needle is firmly adhered to the skin during enhanced CT. After the enhanced CT is completed, the dressing can be torn open in three sections by using the T-shaped suture. After 3 days of separation from the drug inlet, the indwelling needle can be removed separately, while the dressing remains on the hand for pressure hemostasis. There is no need to use additional tape or hemostatic cotton, simplifying the needle removal process and saving needle removal time.

[0020] In this embodiment, the protective film is adapted to the contour of the dressing layer 1. This is provided to protect the dressing layer 1 when the indwelling needle dressing is not in use, so that it remains sticky and does not attract impurities.

[0021] In this embodiment, the dressing layer 1 is a PU film. The above configuration makes the indwelling needle dressing skin-friendly and non-allergenic, waterproof and highly breathable, prolonging the fixation time and preventing infection at the puncture site.

[0022] In this embodiment, the horizontal part of the T-shaped pressure line is on the same straight line as the straight pressure line. The above setting can realize that when the needle is removed, the dressing is divided into three sections by tearing open the T-shaped pressure line. The first section, the drug inlet end 3d, is separated from the skin first. The second section, the gauze cotton 4, is always attached to the skin. The third section, the indwelling needle, is pulled out of the skin.

[0023] In this embodiment, the protective film layer includes at least two flange films 2a and a peritoneum film 2b; the junction of the flange film 2a and the peritoneum film 2b, and the junction where the peritoneum film 2b is divided into two, are all provided with arc-shaped tear 2c. The arc-shaped tear 2c of the peritoneum film 2b are torn in opposite directions, so that it can be torn from the middle of the indwelling needle dressing body to both ends. The pasting position can be found according to the gauze cotton 4 covering the puncture point, effectively fixing the indwelling needle and protecting the puncture point. The flange 1b assists in fixing the drug inlet end 3d and covers the tubing 3b, ensuring that the tubing 3b is not pulled, thus improving the safety and stability of the indwelling needle.

[0024] The working principle of this embodiment is as follows:

[0025] S1 Adhesion: After inserting the indwelling needle into the blood vessel, the medical staff can use their left hand to gently hold and fix the catheter, and use their right hand to pick up the dressing and hand it to their left index finger and thumb to hold it. The right hand then tears open one side of the S-shaped tear film through the semi-circular protrusion. The right hand takes the dressing and aligns the gauze cotton 4 with the puncture point. The abdominal plate 1a of the T-shaped dressing is then horizontally applied to the patient's skin to ensure that the T-shaped dressing is horizontally adhered, which helps to maintain the U-shape of the overall structure of the indwelling needle and facilitates infusion. After adjusting the position, the left hand holds the already applied split film, and the right hand tears open the other half of the split film through the semi-circular protrusion. Both hands adjust the dressing to ensure that it is fully adhered to the skin and the indwelling needle, ensuring that the indwelling needle is stable on the skin and does not easily shift. Then, the fixation end film of the lower flange 1b of the T-shaped dressing is torn open through the arc-shaped tear 2c. Due to the setting of the pressure line, the fixation end film on one side can be divided into two halves. One half surrounds and fixes the indwelling needle tube 3a to prevent the indwelling needle from dislodging from the blood vessel due to excessive injection speed during enhanced CT, thus enhancing the fixation effect. The other half fixes the tubing 3b to prevent the tubing 3b from being pulled. Finally, the fixation end film of the upper flange 1b of the T-shaped dressing is torn open through the arc-shaped tear 2c and cross-covered and adhered to the drug inlet end 3d, so that the drug inlet end 3d is effectively fixed to the skin above the indwelling needle and the indwelling needle as a whole maintains the U-shape required for injection.

[0026] S2 Tear-off: When changing the dressing or tearing off the dressing after completing the infusion, first tear off the fixed end of the upper wing 1b of the T-shaped dressing. Then, use the T-shaped tear at the end of the T-shaped dressing's abdominal plate 1a to detach the drug inlet 3d from the skin. Next, tear the T-shaped tear downwards at the horizontal plate of the T-shaped dressing to detach the tubing 3b. After tearing the T-shaped tear downwards at the end of the T-shaped dressing's abdominal plate 1a, only the indwelling needle 3a will be in contact with the skin. At this point, hold the gauze cotton 4 and pull the indwelling needle out of the skin. The remaining dressing on both sides of the gauze cotton 4 will ensure that the gauze cotton 4 always adheres to the skin and can be left on the hand for pressure hemostasis. There is no need to use additional tape or hemostatic cotton, simplifying the needle removal process and saving needle removal time.

[0027] The present invention has been described in detail above with reference to its embodiments. Various improvements can be made without departing from the core scope of the present invention, and equivalent components can be used to replace some of its parts. As long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. This specification does not exhaustively describe these combinations, merely for the sake of saving space and resources. Therefore, the protection scope of this invention is not limited to the specific embodiments disclosed herein, but covers all technical solutions falling within the scope of the claims.
