Description

Technical Field

[0001] This utility model belongs to the field of pressure ulcer medical technology, and in particular relates to a pressure ulcer relief pad with ventilation effect. Background Technology

[0002] Pressure ulcers, also known as bedsores or pressure sores, are skin and / or tissue injuries localized to the body surface. They are caused by prolonged pressure on the tissue, leading to insufficient blood supply, resulting in skin damage, ulceration, or even necrosis. In the prevention and treatment of pressure ulcers, a medical tool called a pressure ulcer pad is usually required.

[0003] Some existing pressure ulcer pads, in their focus on reducing pressure on human tissues for the prevention and treatment of pressure ulcers, use a large amount of flexible material as the medium for contact with human tissues. However, this may lead to poor ventilation and moisture accumulation, resulting in slow recovery of pressure ulcers or even worsening of symptoms. Therefore, we provide a pressure ulcer pad with ventilation. Utility Model Content

[0004] The purpose of this invention is to provide a pressure ulcer relief pad with ventilation. By setting up support pads, the patient's skin can bear the same pressure evenly when using this product, thus preventing pressure ulcers. Furthermore, the gaps between the support pads allow the patient's skin to remain ventilated, promoting the recovery of pressure ulcers. This solves the problem that some existing pressure ulcer relief pads, when focusing on reducing pressure on human tissues and using a large amount of flexible material as the medium for contact with human tissues, may actually lead to poor ventilation, moisture accumulation, slow recovery of pressure ulcers, or even worsening of symptoms.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pressure ulcer relief pad with ventilation, comprising a main body, a protective mechanism at the top of the main body, and a ventilation mechanism at the bottom of the protective mechanism. The protective mechanism includes a protective groove at the top of the main body, and several airbags at the top of the main body. Support grooves are fixedly connected to the inner walls of the airbags, with two support grooves in total. A support rod is slidably connected to the inner wall of the support groove, and a support pad is fixedly connected to the top of the support rod. The outer wall of the support pad is slidably connected to the inner wall of the airbag. Several sealing gaskets are fixedly connected to the top of the main body, and the inner wall of the sealing gasket is slidably connected to the outer wall of the support pad. Several ventilation holes are provided on the inner wall of the airbag.

[0007] Through the above technical solution, the downward pressure on the support pad causes the support rod to slide in the support groove, thereby compressing the air in the airbag and providing an upward force to the support pad, allowing the patient to lie on the support pad. When the patient turns over and causes uneven force on the support pad, the air in the airbag flows through the vent, thereby balancing the pressure on the support pad and allowing the patient's skin to be evenly supported by each support pad.

[0008] Furthermore, the ventilation mechanism includes a support base fixed to the bottom of the main body, and an air inlet is fixedly connected to the inner wall of the support base.

[0009] Through the above technical solution, the main body can fix the position of the support base, thereby fixing the position of the air inlet.

[0010] Furthermore, the inner wall of the support base is provided with a ventilation pipe, and the inner wall of the ventilation pipe is provided with a number of ventilation openings.

[0011] Through the above technical solution, the support base can fix the position of the ventilation pipe, thereby fixing the position of the ventilation opening, so that the air entering from the air inlet can be ejected from the ventilation opening.

[0012] Furthermore, an air inflator tube is fixedly connected to the inner wall of the airbag, and a threaded tube is fixedly connected to the end of the air inflator tube away from the airbag.

[0013] Through the above technical solution, the airbag can fix the position of the air inflator tube, and thus fix the position of the threaded tube.

[0014] Furthermore, the outer wall of the threaded tube is provided with an air vent, a sealing sleeve is threadedly connected to the outer wall of the threaded tube, and an air pump base is fixedly connected to the front of the threaded tube.

[0015] The above technical solution allows the air vent to be blocked or exposed by rotating the sealing sleeve, thereby enabling the airbag to be inflated or deflated.

[0016] Furthermore, a one-way air nozzle is fixedly connected to the front of the air pump base, a blower sleeve is fixedly connected to the top of the air pump base, and an air pump handle is fixedly connected to the top of the blower sleeve.

[0017] Through the above technical solution, repeatedly pressing the air pump handle can make the blower sleeve blow air, thereby allowing air to enter from the one-way air nozzle and be ejected from the threaded tube.

[0018] Furthermore, an elastic band is fixedly connected to the right side of the main body, and a Velcro surface is fixedly connected to the top of the elastic band.

[0019] Through the above technical solution, the main body can fix the position of the elastic band, thereby fixing the position of the hook and loop fastener.

[0020] Furthermore, an elastic band two is fixedly connected to the left side of the main body, and a Velcro hook is fixedly connected to the bottom of the elastic band two.

[0021] Through the above technical solution, the main body can fix the position of the second elastic band, and then fix the position of the hook and loop fastener. The hook and loop fastener can be bonded to the loop fastener, so that the first elastic band and the second elastic band can be tied to the human body, and thus the device can be fixed to the affected area of ​​the human body.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model features a support pad. The patient places the affected area in the protective groove and presses the skin around the affected area onto the support pad, causing the support pad to slide on the air bladder. This, in turn, causes the support rod to slide downwards along the support groove. At this time, the air bladder contains air, which is compressed to allow the support pad to support the patient's weight. There are ventilation ports connecting adjacent air bladders, so that when the patient tilts their body, air can pass through the ventilation ports and automatically disperse into different air bladders according to the pressure. This ensures that the patient's skin can bear the same pressure evenly when using this product, preventing pressure sores and keeping the patient's skin ventilated, thus promoting the recovery of pressure sores.

[0024] 2. This utility model incorporates an air inlet to draw in air, which is then blown out through a ventilation pipe. Since the ventilation opening is located at the protective groove, the airflow passes through the protective groove and exits through the gaps between the support pads. When the patient uses the device, the pressure ulcer is located at the protective groove. Due to the fluidity of the airflow, the continuously flowing air can effectively relieve the pain of the affected area, stimulate blood circulation, and promote the recovery of the pressure ulcer. Furthermore, when recovering in bed, the affected area is prone to accumulating moisture and heat, which can hinder wound healing. The flowing air can easily remove the accumulated moisture and heat from the affected area, helping the patient recover faster.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5As shown, this utility model is a pressure ulcer relief pad with ventilation effect, including a main body 101. A protective mechanism 1 is provided at the top of the main body 101, and a ventilation mechanism 2 is provided at the bottom of the protective mechanism 1. The protective mechanism 1 includes a protective groove 102 opened at the top of the main body 101. Several airbags 103 are opened at the top of the main body 101. The position of the protective groove 102 and the airbags 103 can be fixed by the main body 101. A support groove 104 is fixedly connected to the inner wall of the airbag 103. There are two support grooves 104. A support rod 105 is slidably connected to the inner wall of the support groove 104. A support pad 106 is fixedly connected to the top of the support rod 105. 3. The support groove 104 can be fixed in position, the support rod 105 can fix the position of the support pad 106, and pressing down the support pad 106 can make the support rod 105 slide in the support groove 104. The outer wall of the support pad 106 is slidably connected to the inner wall of the airbag 103. Several sealing pads 107 are fixedly connected to the top of the main body 101. The inner wall of the sealing pad 107 is slidably connected to the outer wall of the support pad 106. Several vents 108 are opened on the inner wall of the airbag 103. The position of the sealing pad 107 can be fixed by the main body 101, so that when the support pad 106 is pressed down, the air in the airbag 103 can be compressed, so that the air will not leak out from the gap between the airbag 103 and the support pad 106.

[0036] The ventilation mechanism 2 includes a support base 201 fixed to the bottom of the main body 101. An air inlet 202 is fixedly connected to the inner wall of the support base 201. A ventilation pipe 203 is opened on the inner wall of the support base 201, and several ventilation openings 204 are opened on the inner wall of the ventilation pipe 203. The position of the support base 201 can be fixed by the main body 101, thereby fixing the positions of the air inlet 202, the ventilation pipe 203 and the ventilation openings 204, so that air can be injected from the air inlet 202 and blown out from the ventilation openings 204 through the ventilation pipe 203. An air pumping pipe 205 is fixedly connected to the inner wall of the airbag 103. A threaded tube 206 is fixedly connected to one end of the airbag 103 away from the air bladder 103. The airbag 103 can fix the position of the air inflator tube 205, and thus fix the position of the threaded tube 206. An air vent 207 is provided on the outer wall of the threaded tube 206. A sealing sleeve 208 is threadedly connected to the outer wall of the threaded tube 206. An air inflator base 209 is fixedly connected to the front of the threaded tube 206. The threaded tube 206 can fix the position of the air vent 207. Rotating the sealing sleeve 208 can seal or expose the air vent 207. Air blown out from the air inflator base 209 can enter the air inflator tube 205 through the threaded tube 206.

[0037] A one-way air nozzle 210 is fixedly connected to the front of the air pump base 209. A blower sleeve 211 is fixedly connected to the top of the air pump base 209. An air pump handle 212 is fixedly connected to the top of the blower sleeve 211. Repeatedly pressing the air pump handle 212 can cause the blower sleeve 211 to blow air, allowing air to enter the air pump base 209 from the one-way air nozzle 210 and be blown out from the threaded tube 206. An elastic band 213 is fixedly connected to the right side of the main body 101. A component is fixedly connected to the top of the elastic band 213. The hook and loop fastener 214 has an elastic band 215 fixedly connected to the left side of the main body 101. The bottom of the elastic band 215 has a hook and loop fastener 216 fixedly connected to it. The main body 101 can fix the positions of the elastic band 213 and the elastic band 215, thereby fixing the positions of the hook and loop fastener 214 and the hook and loop fastener 216. The hook and loop fastener 214 and the hook and loop fastener 216 can stick to each other, and the elastic band 213 and the elastic band 215 fix the device to the affected area.

[0038] One specific application of this embodiment is:

[0039] The operator first aligns the affected area with the protective groove 102 and presses the skin around the affected area onto the support pad 106. Then, the sealing sleeve 208 is rotated to block the vent 207. The operator then repeatedly presses the air inflator 212, allowing air to enter the one-way nozzle 210, pass through the threaded tube 206 and the air inflator 205, and finally enter the airbag 103. The air in the airbag 103 gradually increases and compresses, causing the support pad 106 to experience an upward force and gradually increase in size. This eventually causes the support rod 105 to slide upwards along the support groove 104, lifting the support pad 106 and the person. After adjusting to the appropriate position, the operator stops pressing the air inflator 212 and connects the elastic band 213 to the elastic band 214. The second strap 215 passes around the human body, ultimately adhering the hook side 214 and the loop side 216 of the Velcro, fixing the device to the affected area. Then, air is injected through the air inlet 202, passes through the ventilation pipe 203, and is ejected from the ventilation outlet 204. At this time, the air enters the protective groove 102 and flows out through the gaps in the support pad 106, which serves as ventilation. When the patient turns over or moves, the pressure on the support pad 106 changes, causing the air in the airbag 103 to flow out through the vent 108, so that the pressure in the airbag 103 reaches a dynamic balance, and ultimately the skin can evenly bear the same pressure from the support pad 106, avoiding the formation or aggravation of pressure sores.
