[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] An indwelling needle dressing for observing the amount of blood seepage around the puncture point, such as Figure 1 , 2As shown in , 3, 4, and 5, it includes a transparent adhesive tape 1, the adhesive side of the adhesive tape 1 can be adhered to the skin, and the adhesive tape 1 is provided with a protective film covering the adhesive side, and the protective film can be torn off from the adhesive tape 1. The adhesiveness of the adhesive tape 1 will not be affected after the protective film is torn off, and its characteristics are: a first cotton pad 2 and a second cotton pad 3 that are annular and can absorb blood are fixedly installed on the adhesive tape 1, the first cotton pad 2 and the second cotton pad 3 are fixedly installed on the adhesive side of the adhesive tape 1, the first cotton pad 2 and the second cotton pad 3 are coaxially arranged, the second cotton pad 3 is larger than the first cotton pad 2, the first cotton pad 2 is located on the inner side of the second cotton pad 3, the first cotton pad 2 and the second cotton pad 3 are connected by a strip-shaped third cotton pad 4, and the first cotton pad 2, the second cotton pad 3, and the third cotton pad 4 are an integrated structure. The utility model has a simple structure and ingenious design. By arranging a blood-absorbing cotton pad, it can absorb the blood seeping from the puncture point of the indwelling needle without blocking the puncture point. The amount of blood seeping around the puncture point of the indwelling needle and the puncture point can be clearly seen for easy observation, providing a basis for judging whether to remove the indwelling needle in advance. It can meet actual needs and is suitable for promotion. When using the utility model, after the indwelling needle punctures the skin, the protective film is torn off, and the center hole of the first cotton pad 2 is aligned with the puncture point, and then the tape 1 is pasted on the skin. At this time, the tape 1 fixes the indwelling needle on the skin surface to restrict its movement. When the puncture point oozes blood, the first cotton pad 2 absorbs the blood, and the first cotton pad 2 absorbs and diffuses the blood to the third cotton pad 4 after it is fully absorbed. After the third cotton pad 4 is full, it diffuses to the second cotton pad 3. The amount of oozing blood is observed by the changes in the adsorption area and color on the first cotton pad 2, the second cotton pad 3, and the third cotton pad 4. According to the amount of oozing blood and the patient's complaint, it is decided whether to remove the tube in advance. When the amount of oozing blood reaches a certain area and color, it is prompted that the patient may have a bleeding tendency, and the doctor is reported in time to adjust the type, dosage or frequency of medication to avoid the occurrence of heavy bleeding. The center hole of the ring-shaped first cotton pad 2 makes the puncture point clearly visible, which is convenient for observing whether the puncture point is red, swollen, or the indwelling needle is out of place.
[0017] Specifically, as shown in the figure, the third cotton pad 4 and the second cotton pad 3 described in this embodiment are respectively provided with several thin line-shaped imprints 20, and the imprints 20 on the second cotton pad 3 are evenly distributed in a circle to divide the second cotton pad 3 into several sector-shaped areas. The imprints 20 are formed at the compacted parts of the second cotton pad 3 or the third cotton pad 4, and the edges of the second cotton pad 3 and the third cotton pad 4 are not connected to the imprints 20. The cotton materials at the positions where the imprints 20 are located on the second cotton pad 3 and the third cotton pad 4 are compacted, and the blood-absorbent property at the positions where the imprints 20 are located is less than that at the positions where there are no imprints 20. The blood absorbency at the imprint 20 is poor, and the blood diffusion speed is slow, which can delay the diffusion of blood on the second cotton pad 3 and the third cotton pad 4, so that each part of the third cotton pad 4 has enough time to absorb blood. After the blood is fully absorbed, the blood enters the second cotton pad 3 from the gaps at both ends of the imprint 20 and is absorbed by the second cotton pad 3. The imprint 20 on the second cotton pad 3 can also delay the diffusion of blood, so that the fan-shaped area corresponding to the second cotton pad 3 can absorb enough blood. After the fan-shaped area is fully absorbed with blood, the newly absorbed blood can enter the next fan-shaped area from the gaps at both ends of the imprint 20, so that the diffusion of blood is more regular and concentrated, so that the amount of bleeding can be observed more conveniently.
[0018] Specifically, as shown in the figure, the protective film of this embodiment includes an upper film 30 and a lower film 31, the upper film 30 covers the upper part of the tape 1, and the lower film 31 covers the lower part of the tape 1. The sides of the upper film 30 and the lower film 31 that are in contact with the tape 1 are smooth surfaces, a part of the upper film 30 covers the lower film 31, and the upper film 30 and the lower film 31 completely cover the first cotton pad 2, the second cotton pad 3, and the third cotton pad 4, and a part of the lower side of the lower film 31 is extended and does not contact the tape 1. When using the tape, the upper film 30 is torn off, and then the lower film 31 is torn off through the extended part of the lower film 31, so that the glue on the tape 1 is exposed, and the tape 1 can be attached to the skin.
[0019] Further, as shown in the figure, the upper film 30 and the lower film 31 described in the present embodiment are provided with the same circular through groove 40, the through groove 40 is coaxially arranged with the first cotton pad 2, one side of the through groove 40 is provided with a circular protective film 41 for covering it, the circular protective film 41 is pasted on the adhesive tape 1, the circular protective film 41 can be torn off, the adhesive tape 1 between the first cotton pad 2 and the second cotton pad 3 is pasted together with a part of the circular protective film 41, the through groove 40 is in contact with the upper film 30 and the lower film 31, and a part of the upper film 30 and the lower film 31 is covered by the circular protective film 41. When in use, the circular protective film 41 is torn off first, the through groove 40 is aligned with the puncture point, and then the upper film 30 and the lower film 31 are torn off in sequence, and the adhesive tape 1 can be pasted on the skin, so that it is more convenient to align the center hole of the first cotton pad 2 with the puncture point.
[0020] Furthermore, as shown in the figure, the third cotton pad 4 of this embodiment is arranged parallel to the long side of the tape 1. When the tape 1 is attached to the skin, the long side of the tape 1 is perpendicular to the indwelling needle. At this time, the third cotton pad 4 is located on the right side of the indwelling needle, which less blocks the indwelling needle, so that the indwelling needle and bleeding can be observed more conveniently.
[0021] Furthermore, as shown in the figure, the adhesive tape 1 of this embodiment is octagonal. Setting the adhesive tape 1 to be octagonal saves materials and reduces costs compared to a rectangle, and does not affect the normal use of the adhesive tape 1.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
