[0031] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] Embodiment 1

[0033] Please refer to Figures 1-4 , the technical solution of an improved intravenous infusion patch provided in this embodiment is as follows: including

[0034] An infusion patch fixing member 1, including an infusion patch fixing piece 11, a palm area covering piece 12 and an infusion patch reinforcement member 13 that are connected in sequence, wherein an observation window 111 is provided on the infusion patch fixing piece 11, and an infusion patch reinforcement window 131 is provided on the infusion patch reinforcement member 13;

[0035] An infusion patch 2, fixedly arranged on the infusion patch fixing piece 11 and covering the observation window 111;

[0036] An infusion patch protection member 3, detachably connected to one end of the infusion patch 2 that is not connected to the infusion patch fixing member 1.

[0037] Specifically, a rectangular second hollow part is provided in the central area of the infusion patch reinforcement member 13, and the second hollow part is the infusion patch reinforcement window 131. In order to completely wrap the peripheral area of the observation window 111 without interfering with the observation window 111, the length of the infusion patch reinforcement window 131 is designed to be longer than the length of the observation window 111, and the width of the infusion patch reinforcement window 131 is designed to match the width of the observation window 111.

[0038] In specific implementation, the infusion patch fixing member 1 is designed as an integral structure. When in use, such as Figure 3As shown, the infusion patch fixing piece 11 is arranged in the puncture area of the patient's dorsum of the hand. After tearing off the infusion patch protective piece 3, it is attached. At this time, the infusion patch fixing piece 11 is near the thumb at the left part shown in Figure 1 ; after the infusion patch 2 in the infusion patch fixing piece 11 is attached, the palm area covering piece 12 is wound around the palm along the side of the hand; after the infusion patch reinforcement window 131 in the infusion patch reinforcement piece 13 passes over the thumb (that is, the thumb is in the infusion patch reinforcement window 131), it is attached to the peripheral area of the observation window 111 of the infusion patch fixing piece 11 to complete the fixation. A rectangular first hollow part is provided in the center of the infusion patch fixing piece 11, and the rectangular first hollow part is the observation window 111.

[0039] Preferably, during actual use, the size of the rectangular first hollow part is closely related to the size of the patient's dorsum of the hand. For example, the length and width of a person's dorsum of the hand are usually between 4 cm and 8 cm. Therefore, the size of the rectangular first hollow part can be designed to be between 3 cm * 3 cm and 6 cm * 6 cm to meet the usage requirements of patients of different ages. Specifically, the infusion patch 2 is a transparent dressing. Taking the PU material as an example, the infusion patch 2 can be composed of a PU film and a pressure-sensitive adhesive coated on the side wall of the PU film. Among them, one end of the PU film that does not contact the infusion patch fixing piece 11 is coated with a pressure-sensitive adhesive. The length of the infusion patch 2 is longer than the length of the observation window 111, and the width of the infusion patch 2 is wider than the width of the observation window 111; in addition, the area of the infusion patch 2 exceeding the observation window 111 can also be coated with a pressure-sensitive adhesive or other medical glues that can achieve adhesion to fixedly connect the infusion patch 2 and the infusion patch fixing piece 1.

[0040] Specifically, the infusion patch protective piece 3 is a release paper, and the size of the infusion patch protective piece 3 matches the size of the infusion patch 2. In order to be able to tear off the release paper more conveniently, the size of the infusion patch protective piece 3 can also be set to be slightly larger than the infusion patch 2, and the part of the infusion patch protective piece 3 exceeding the infusion patch 2 forms a tearing guide area.

[0041] Specifically, the infusion patch fixing piece 1 is a medical self-adhesive elastic bandage. The core characteristics of the self-adhesive elastic bandage lie in its self-adhesiveness and elasticity. This kind of bandage is usually composed of a fiber material and an adhesive mixed in the fiber material. Among them, the fiber material provides the necessary elasticity and stretchability, and the adhesive is responsible for generating adhesiveness only when under pressure. Therefore, the infusion patch fixing piece itself will not directly adhere to the dorsum of the hand, so it can be widely applicable to people with sensitive skin. When the infusion patch reinforcement piece 13 is stretched, the adhesive layer on the infusion patch reinforcement piece 13 will generate adhesiveness under the action of pressure, so that the infusion patch reinforcement piece 13 is closely attached and fixed on the infusion patch fixing piece 11. In actual use, cartoon prints can also be printed on the infusion patch fixing piece 1 for children's infusion to relieve the infusion pressure of children.

[0042] In specific implementation, regarding the materials of the medical self-adhesive elastic bandage: 1. Non-woven self-adhesive elastic bandage (made of spunbond non-woven fabric, spandex, and specially treated medical glue). 2. PBT self-adhesive elastic bandage: (made of nylon, viscose fiber, and specially treated medical glue). 3. Cotton self-adhesive elastic bandage: (made of cotton yarn and specially treated medical glue). 4. CT self-adhesive elastic bandage: (made of cotton yarn, spandex, CT, and specially treated medical glue). 5. Nylon self-adhesive elastic bandage (made of cotton yarn, spandex, nylon, medical latex thread, and specially treated medical glue) can all be used in this design.

[0043] In specific implementation, as Figure 4 shown, because of the flexible foldability and self-adhesive characteristics of the medical self-adhesive elastic bandage, when the patient's hand is relatively thin, the end of the palm area covering piece 12 connected to the infusion patch fixing piece 11 can be slightly folded inward to shorten the length of the palm area covering piece 12. After such folding, repeating the above usage steps can meet the usage requirements of patients with thin hands. In addition, regarding the stability problem of the folding area 4, the width of the end of the infusion patch reinforcement 131 that is not connected to the palm area covering piece 12 (i.e., Figure 1 the rightmost end) can be set wider, so that this area can completely cover the folding area 4 and be fixedly adhered to the periphery of the folding area 4 (i.e., as Figure 3 shown in d, this widened area can cover the folding area 4 and be attached to the palm area).

[0044] Embodiment 2

[0045] In specific implementation, in addition to being used for dorsal hand infusion, this design can also be used for the feet such as the instep and ankle, or for the limbs. The usage method is the same as that in Embodiment 1. The infusion patch fixing piece 11 is configured at the puncture area of the patient's foot or limb. After tearing off the infusion patch protective piece 3, it is attached. After the infusion patch 2 in the infusion patch fixing piece 11 is attached, the palm area covering piece 12 is wound around the side of the foot or limb along the side of the foot or limb on the side away from the puncture area; after the infusion patch reinforcement 13 winds around the foot or limb for half a circle, it is attached to the outer peripheral area of the observation window 111 of the infusion patch fixing piece 11 to complete the fixation. Similar to Embodiment 1, the length of the palm area covering piece 12 can also be adjusted by folding to meet the usage requirements of patients with different leg circumferences or different arm circumferences. Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
