Description

Technical Field

[0001] This utility model relates to the field of hospital supplies, and in particular to a fixation dressing for hemodialysis puncture needles. Background Technology

[0002] Currently, commonly used methods for fixing hemodialysis puncture needles include: Figure 1 As shown, an adhesive tape is used to cover the needle handle and stick it to the skin. This tape helps to fix the needle handle and prevent the needle from falling out. A dressing is used to cover the puncture site for protection. Tape can also be used to wrap the catheter and then stick it to the skin to further fix the hemodialysis puncture needle and prevent the needle from falling out.

[0003] Some patents also disclose fixation dressings for hemodialysis puncture needles. For example, patent application number 202322670268.3 discloses a dressing assembly for a hemodialysis puncture needle, including a main patch with an adhesive side. When in use, the adhesive side of the main patch is fixedly attached to the double wings of the puncture needle and the skin to bond and fix the double wings of the puncture needle to the surface of the human skin; a needle body fixing patch, which is fixedly attached to the adhesive side of the main patch. When in use, the adhesive side of the needle body fixing patch is fixedly attached to the needle body of the puncture needle and the skin to bond and fix the needle body of the puncture needle to the surface of the human skin; and a tube body fixing strap, which is integrally connected to the edge of the main patch. When in use, the adhesive side of the tube body fixing strap is fixedly attached to the tubing of the puncture needle and the skin to bond and fix the tubing of the puncture needle to the surface of the human skin.

[0004] Bleeding may occur at the puncture site of the hemodialysis needle. This bleeding needs to be addressed promptly, but because the dressing covers the puncture site, the bleeding often goes unnoticed until the blood flows outside the dressing or soaks through it, which can delay detection for a considerable time. This drawback is present in both the commonly used hemodialysis needle fixation methods and the dressing disclosed in patent application number 202322670268.3. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hemodialysis puncture needle fixation dressing that facilitates timely detection of bleeding at the hemodialysis puncture site.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows: the hemodialysis puncture needle fixation dressing includes a needle handle pad, a needle handle fixation patch, a capillary tube, and a puncture point covering patch; when the hemodialysis puncture needle fixation dressing is unfolded and laid flat, the needle handle fixation patch is located to the left or right of the needle handle pad, and the puncture point covering patch is located in front of the needle handle fixation patch; the lower surface of the needle handle pad has adhesive, and the adhesive is covered with a first protective film; the needle handle fixation patch is connected to the puncture point covering patch, the upper surface of the needle handle fixation patch has adhesive, and the adhesive is covered with a second protective film; a capillary tube sleeve is connected to the middle of the lower surface of the needle handle fixation patch, the capillary tube sleeve is arranged in the front-back direction, the capillary tube passes through the capillary tube sleeve, and the front end of the capillary tube passes through the middle of the puncture point covering patch from bottom to top, and the capillary tube is transparent.

[0007] Furthermore, the capillary tip protrudes above the upper surface of the puncture site covering patch, and the distance between the capillary tip and the upper surface of the puncture site covering patch is half the diameter of the hemodialysis puncture needle.

[0008] Furthermore, there are two capillary sleeves and two capillary tubes. The two capillary sleeves are spaced apart in the left and right direction, and the capillary tubes are set in a one-to-one correspondence with the capillary sleeves. The distance between the front ends of the two capillary tubes matches the diameter of the hemodialysis puncture needle.

[0009] Furthermore, the capillary tubes are made of plastic.

[0010] Furthermore, the capillary sheath is transparent.

[0011] Furthermore, the needle handle fixing sticker and the needle handle pad are connected by a thin film.

[0012] Furthermore, the hemodialysis puncture needle fixation dressing includes two folded patches, which are arranged in the front-to-back direction and spaced apart in the left-to-right direction. One end of the folded patch is connected to the middle of the needle handle pad.

[0013] The beneficial effects of this utility model are: when using this utility model, firstly as follows... Figure 5 As shown, place the needle handle pad under the needle handle, peel off the first protective film, and stick it to the skin. (Another example follows.) Figure 6 As shown, the needle handle fixing adhesive is flipped over and placed over the needle handle and needle handle pad. The second protective film is then peeled off and pasted onto the needle handle and needle handle pad. This secures the needle handle, thus securing the hemodialysis puncture needle and preventing needle dislodgement. Compared to existing methods that directly cover the needle handle and then adhere it to the skin, this method avoids direct contact between the needle handle and the skin, improving comfort and providing better needle handle fixation.

[0014] Then it was still the same Figure 6As shown, adjust the position of the capillary tube covering the puncture site by moving it back and forth, so that the center of the covering is aligned with the puncture site and the tip of the capillary tube is roughly against the needle at the puncture site. Then, apply the covering to the skin. The covering protects the puncture site. If blood seeps out at the puncture site, the blood is located at the tip of the capillary tube. The capillary's suction draws the blood into the capillary tube, making the blood under the covering visible and allowing for rapid detection and treatment of the bleeding.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 2 to 4 As shown, the hemodialysis puncture needle fixation dressing includes a needle handle pad 1, a needle handle fixation patch 2, a capillary tube 4, and a puncture point covering patch 3. When the hemodialysis puncture needle fixation dressing is unfolded and laid flat, the needle handle fixation patch 2 is located to the left or right of the needle handle pad 1, and the puncture point covering patch 3 is located in front of the needle handle fixation patch 2. The lower surface of the needle handle pad 1 has adhesive, which is covered with a first protective film. The needle handle fixation patch 2 is connected to the puncture point covering patch 3. The upper surface of the needle handle fixation patch 2 has adhesive, which is covered with a second protective film. A capillary tube sleeve 6 is connected to the middle of the lower surface of the needle handle fixation patch 2. The capillary tube sleeve 6 is arranged in the front-back direction. The capillary tube 4 passes through the capillary tube sleeve 6, and the front end of the capillary tube 4 passes through the middle of the puncture point covering patch 3 from bottom to top. The capillary tube is transparent.

[0024] When using this utility model, first as follows: Figure 5 As shown, place the needle handle pad 1 under the needle handle 71, peel off the first protective film, and stick it to the skin. (The text repeats itself here.) Figure 6 As shown, the needle handle fixing adhesive 2 is flipped over and placed over the needle handle 71 and needle handle pad 1. The second protective film is then peeled off and pasted onto the needle handle 71 and needle handle pad 1. This secures the needle handle 71, thus securing the hemodialysis puncture needle 7 and preventing the needle tip 72 from dislodging. Compared to existing methods that directly cover the needle handle 71 and stick it to the skin, this method avoids direct contact between the needle handle 71 and the skin, improving comfort and providing a better fixation effect for the needle handle 71.

[0025] Then it was still the same Figure 6 As shown, the capillary tube 4 is moved back and forth to adjust the position of the puncture point covering patch 3, so that the middle of the puncture point covering patch 3 is aligned with the puncture point, and the front end of the capillary tube 4 is basically in contact with the needle 72 at the puncture point. Then, the puncture point covering patch 3 is applied to the skin, where it provides protection for the puncture point. If blood seeps out at the puncture point, the blood is located at the front end of the capillary tube 4. The suction effect of the capillary tube 4 draws the blood into it, and the blood under the puncture point covering patch 3 enters the capillary tube 4 on the patch 3, becoming visible and allowing for rapid detection and treatment of the bleeding.

[0026] The needle handle pad 1, needle handle fixing patch 2, and puncture point covering patch 3 are all made of commonly used dressing materials, such as non-woven fabric. The capillary tube 4 refers to a very small inner diameter tube, commonly used in hospitals, for example, in micro-blood collection using blood collection capillaries. The capillary tube 4 is based on existing blood collection capillaries, which are made of either plastic or glass; plastic is preferred for the capillary tube 4 as it allows for some flexibility. The capillary sleeve 6 serves to fix the capillary tube 4. The capillary sleeve 6 can be made of non-woven fabric, and preferably is transparent to allow observation of whether there is blood inside the capillary tube 4. The transparent capillary sleeve 6 can be made of flexible transparent plastic.

[0027] The capillary tube 4 has the specific shape shown in Figure 4, with a slight bend at the front. The front end of the capillary tube 4 protrudes from the upper surface of the puncture site covering patch 3, and the distance between the front end of the capillary tube 4 and the upper surface of the puncture site covering patch 3 is half the diameter of the hemodialysis puncture needle 7. The significance of this design parameter is that the capillary tube 4 is close to the needle 72, which cushions the capillary tube 4, preventing the front end of the capillary tube 4 from contacting the patient's skin. However, if the front end of the capillary tube 4 is flush with the surface of the puncture site covering patch 3, the distance between the front end of the capillary tube 4 and the puncture site will be slightly farther due to the larger diameter of the needle 72. The distance between the front end of the capillary tube 4 and the lower surface of the puncture site covering patch 3 is half the diameter of the hemodialysis puncture needle 7, which allows the front end of the capillary tube 4 to be closer to the puncture site, facilitating blood aspiration, without contacting the skin at the puncture site.

[0028] Furthermore, this utility model preferably uses two capillary sleeves 6 and two capillary tubes 4. The two capillary sleeves 6 are spaced apart in the left-right direction, and the capillary tubes 4 are arranged in a one-to-one correspondence with the capillary sleeves 6. The distance between the front ends of the two capillary tubes 4 matches the diameter of the hemodialysis puncture needle 7. Thus, when the puncture point covering patch 3 is applied, the two capillary tubes 4 are located on the left and right sides of the needle 72, respectively. Setting two capillary tubes 4 ensures that blood seepage to both sides of the needle 72 can be detected, facilitating early detection of bleeding. The distance between the front ends of the two capillary tubes 4 matching the diameter of the hemodialysis puncture needle 7 means that the distance between the front ends of the two capillary tubes 4 is slightly larger than the diameter of the hemodialysis puncture needle 7, so that the two capillary tubes 4 are located on the left and right sides of the needle 72, respectively, and are both very close to the needle 72.

[0029] The needle handle fixing sticker 2 needs to be flipped over and placed on the needle handle pad 1. To facilitate the flipping of the needle handle fixing sticker 2, it is preferable that the needle handle fixing sticker 2 and the needle handle pad 1 are connected by a thin film.

[0030] Furthermore, the preferred embodiment of this utility model includes two folded patches 5, which are arranged in the front-to-back direction and spaced apart in the left-to-right direction. One end of each folded patch 5 is connected to the middle of the needle handle pad 1.

[0031] like Figure 5 As shown, the function of the reverse folding sticker 5 is to fold back and cover the needle handle 71. Its reverse fold is located at the rear edge of the needle handle 71, which better prevents the needle handle 71 from shifting backward.

[0032] It should be noted that the aforementioned up-down direction refers to the unfolded, flat position of the hemodialysis needle fixation dressing. When the hemodialysis needle fixation dressing is in use, the upper surface of the needle handle fixation patch 2 and the puncture point covering patch 3 should face downwards, and the lower surface should face upwards.
