AI Technical Summary
Existing bandages are difficult to keep the wound in place effectively after spinal surgery, leading to problems such as bleeding and seepage, and they are not comfortable or stable enough.
A pressure bandage was designed, which uses sewn straps, elastic bands and elastic pressure frames, combined with medical gauze and air bladders. The elastic bands use their elasticity to pull back and close the wound sides, and the bandages are fixed in place by Velcro and air bladders. An absorbent sponge pad is added to absorb exudate.
It effectively keeps the wound in place on both sides, preventing loosening and cracking, improving comfort and stability, reducing exudation and bleeding, and lowering treatment costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a pressure bandage. Background Technology
[0002] After spinal surgery, because the patient's wound is located on the back, the incision heals more slowly. Also, because the human back is not flat but has an arc shape, the wound is prone to cracking and cannot maintain proper adhesion, which can easily lead to bleeding and seepage.
[0003] In clinical treatment, bandages are used to apply pressure to the incision site. This helps the wound heal, keeps the wound taut, and allows it to close properly. Secondly, it can prevent bleeding and seepage, thus avoiding the need to change bed sheets and clothes, reducing subsequent care troubles.
[0004] Current treatment methods mostly involve tightly bandaging the wound with gauze, and adding absorbent materials such as clean towels or thick gauze strips to the back wound. However, keeping the gauze taut mainly ensures that it adheres to the wound and effectively absorbs the exudate. It is not very effective in bringing the sides of the wound closer together. Moreover, the bandage is often too tight and uncomfortable for the patient due to daily activities such as moving around, eating, and drinking, while being too loose results in no effect at all.
[0005] Therefore, a pressure bandage that can meet the above requirements is needed. Utility Model Content
[0006] To address the aforementioned problems, this utility model provides a pressure bandage.
[0007] This utility model is achieved through the following technical solution: A pressure bandage includes two sewn straps, with an elastic band connecting the two sewn straps. Elastic pressure frames are sewn onto the top and bottom of the elastic band. The two sewn straps, the elastic band, and the multiple elastic pressure frames are wrapped with medical gauze. A second Velcro side is sewn onto one end of the medical gauze, and a second Velcro backing side is sewn onto the other end of the medical gauze.
[0008] Preferably, the medical gauze has a first airbag fixed on each side.
[0009] Preferably, a second airbag is fixedly installed on the inner wall of the medical gauze.
[0010] Preferably, the medical gauze is wrapped with a movable thickened sponge pad, and absorbent gauze is sewn to one side of the thickened sponge pad.
[0011] Preferably, a second hook and loop fastener is sewn onto the outer wall of the thickened sponge pad, and a second hook and loop fastener is sewn onto the outer wall of the medical gauze.
[0012] Preferably, a fastener is fixed to the outer wall of one end of the thickened sponge pad, and a buckle is fixed to the outer wall of the other end of the thickened sponge pad. The buckle extends into the fastener and is connected to it.
[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: due to the elasticity of the elastic band, the skin on the back of the human body will be tightened towards the middle, and the point of tightening force is the contact point between each elastic pressure frame and the human skin through the medical gauze. In this way, there is an inward contraction force from both sides of the lower back to the wound, which can effectively ensure that the two sides of the wound can fit together and effectively wrap the entire lower back. This ensures that the second airbag fits the skin of the lower back and the first airbag maintains an effective friction force with the sides of the front abdomen, thus avoiding the situation of loosening and cracking of the wound due to shaking.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a pressure bandage includes two sewn-on straps 1, with an elastic band 2 connecting the two straps 1. Elastic retainers 3 are sewn onto the top and bottom of the elastic band 2. Medical gauze 4 is wrapped around the two straps 1, the elastic band 2, and the multiple elastic retainers 3. A second Velcro side 10 is sewn onto one end of the medical gauze 4, and a second Velcro backing side 11 is sewn onto the other end. In use, the two ends of the medical gauze 4 are first pulled. Because the medical gauze 4 is sewn together with the two straps 1, the two straps 1 are also subjected to force, thus keeping the elastic band 2 taut. The multiple elastic retainers... The spacing between the pressure frames 3 is thus increased. At this point, maintain this state and fasten it tightly to the patient's wound. Bring the two ends of the medical gauze 4 together at the patient's abdomen, and then slowly release the force. As a result of the elastic band 2's elasticity, the skin on the back of the human body will tighten towards the center. The point of tightening force is at the contact point between each elastic pressure frame 3 and the human skin through the medical gauze 4. Thus, there is an inward contraction force from the sides of the lower back to the wound, which can effectively ensure that the two sides of the wound can be adhered. Then, attach the second Velcro mother side 11 and the second Velcro daughter side 10 to keep the whole thing fixed.
[0017] The medical gauze 4 has two first air bags 8 fixed on each side. The two first air bags 8 can effectively fit the depressions on both sides of the patient's abdomen and fit the curve of the human body tightly. Firstly, it can effectively prevent the whole body from loosening or shaking. Secondly, it can fit the curve of the human body before the patient eats or drinks and after digestion to ensure overall stability.
[0018] A second airbag 12 is fixedly installed on the inner wall of the medical gauze 4. The second airbag 12 is long and strip-shaped. After being applied to the patient's back, it can effectively wrap the entire lower back, so that the second airbag 12 fits the skin of the lower back and maintains an effective friction force. This prevents the wound from loosening or cracking due to shaking.
[0019] A movable thickened sponge pad 7 is wrapped around the medical gauze 4. An absorbent gauze 9 is sewn to one side of the thickened sponge pad 7, which can effectively absorb the exudate from the patient's wound.
[0020] The outer wall of the thickened sponge pad 7 is sewn with a second Velcro mother side 11, and the outer wall of the medical gauze 4 is sewn with a second Velcro daughter side 10. This can effectively fix the thickened sponge pad 7, thereby preventing displacement caused by the patient's movement, and can be regularly washed and disinfected, reducing treatment costs.
[0021] A fastener is fixed to one end of the outer wall of the thickened sponge pad 7, and a buckle is fixed to the other end of the outer wall of the thickened sponge pad 7. The buckle extends into the fastener and is connected to it. The buckle is used to ensure the stability of the thickened sponge pad 7, so that it can stably perform absorption and breathability.
