Description

Technical Field

[0001] The utility model belongs to the technical field of medical care products, in particular to a water bag for preventing pressure sores. Background Art

[0002] Pressure sores, also known as pressure ulcers or bedsores, are caused by long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Most patients with advanced cancer have symptoms such as emaciation and malnutrition, which increase the risk of pressure injuries.

[0003] A search revealed Chinese patent publication number CN213218455U, which discloses a pressure sore prevention water bag comprising a bag body, a sealing clamp connected to the bag opening, a connection slot formed on the sealing clamp, the bag opening being located within the connection slot, a liquid injection tube fixedly connected to the sealing clamp, the liquid injection tube communicating with the bag body, a sealing cap connected to the liquid injection tube, the sealing cap cooperating with the liquid injection tube, a plurality of reinforcing patches fixedly connected to both sides of the bag body, a reinforcing strip fixedly connected to the bag body, the reinforcing strips being located between the reinforcing strips, and a plastic ear fixedly connected to the bag body. The utility model connects the bag body to the sealing clamp, the liquid injection tube being connected to the sealing clamp, liquid being introduced from the liquid injection tube into the bag body, and the liquid injection tube being sealed using the sealing cap structure, thereby completing the preparation of the pressure sore prevention water bag. The reinforcing strips are connected to both sides of the bag body, and when the water bag is subjected to pressure, tension is distributed on both sides of the water bag. The reinforcing strips reinforce the water bag, making it less likely to rupture under pressure, thus enhancing its practicality.

[0004] The use of anti-pressure sore water bags can provide support for patients, relieve local tissue pressure, and effectively prevent the occurrence of pressure sores. Since the device needs to be subjected to continuous pressure during use, and the middle part of the device is the main pressure point, but the existing device does not strengthen this part, such as the above-mentioned solution. The device is not protected from the middle, resulting in the device being extremely susceptible to pressure and instability, resulting in rupture, affecting the actual use effect. Utility Model Content

[0005] The present invention addresses the problem that the existing technology does not focus on protecting the middle part of the device, and proposes the following technical solutions:

[0006] A water bag for preventing pressure sores comprises a support bag, a pressure-resistant structure installed outside the support bag, and a material injection structure.

[0007] The pressure-resistant structure includes reinforcing ribs, connecting strips, fixed rings, connecting rings, and relief frames. The reinforcing ribs are installed on the outside of the support bag, and both ends of the reinforcing ribs extend to the upper and lower sides of the support bag. The relief frame is installed on the inner wall of the connecting ring, the connecting strip is installed on the outside of the connecting ring, and one end of the connecting strip away from the connecting ring is installed on the upper end of the fixing ring, and the connecting ring, the relief frame, the connecting ring, and the fixing ring are all installed on the outer surface of the support bag.

[0008] The injection structure includes an injection groove and a sealing head. The sealing head is screwed together with the injection groove. The injection groove is opened in the middle of one side of the support bag, and the injection groove is connected to the inside of the support bag.

[0009] Under the simultaneous support of the pressure-resistant structure and the water inside the support bag, the pressure is dispersed from the middle of the device to resist, thereby improving the pressure resistance of the middle part and the entire device and improving its safety during use.

[0010] As a preferred embodiment of the above technical solution, the connecting ring is located in the middle of the upper end of the support bag, and there are at least two connecting rings, and the two connecting rings are located on opposite sides of the support bag, and the connection methods of the two connecting rings are consistent.

[0011] Under the simultaneous action of the pressure-resistant structures on both sides of the support bag, when one side of the support bag is subjected to pressure, the pressure-resistant structures on both sides provide support at the same time, thereby achieving a double support effect for the pressure exerted on the device.

[0012] As a preferred embodiment of the above technical solution, the two fixing rings are both located outside the support bag, and the fixing rings are fixedly connected to a plurality of the reinforcing ribs, and the connecting strip is located between the two reinforcing ribs.

[0013] Under the tension transmission of the support bag itself and the simultaneous connection of the two fixing rings and the reinforcing ribs, the pressure-resistant structure on the other side can quickly share and relieve the pressure, further improving the overall pressure resistance of the device.

[0014] As a preferred embodiment of the above technical solution, the connecting strip is located at one end of the support bag and at a side of the support bag, and the junction between the support bag and the reinforcing rib is located at a corner of the support bag.

[0015] By arranging the connecting strips and reinforcing ribs at the corners of the support bag, it is convenient to focus on protecting the side of the support bag.

[0016] As a preferred embodiment of the above technical solution, both ends of the support bag are round, and the support bag itself is transparent.

[0017] By setting the support bag as a whole to be cylindrical, the contact area of the device during use is increased while the water volume remains unchanged, thereby ensuring the compressive strength of the device.

[0018] As a preferred embodiment of the above technical solution, a support groove is provided at one end of the sealing head away from the injection groove, and a cross shape is formed between the support grooves.

[0019] The injection groove is set inside the support bag so that the outer side of the support bag is smooth and non-protruding, which facilitates the actual use experience and prevents leakage caused by accidental touch.

[0020] The beneficial effects of the utility model are:

[0021] (1) Under the simultaneous support of the pressure-resistant structure and the water inside the support bag, the pressure is dispersed from the middle part of the device to resist, thereby improving the pressure resistance of the middle part and the entire device and improving its safety during use;

[0022] (2) Under the simultaneous action of the pressure-resistant structures on both sides of the support bag, when one side of the support bag is subjected to pressure, the pressure-resistant structures on both sides support it at the same time, thereby achieving a double support effect for the pressure on the device.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Example

[0031] Figure 1-Figure 5 What is shown is a schematic diagram of the overall structure of a specific embodiment of the utility model. Figure 1-Figure 5In the invention, a water bag for preventing pressure sores comprises a support bag 1, a pressure-resistant structure installed on the outside of the support bag 1, and a material injection structure.

[0032] The pressure-resistant structure includes reinforcing ribs 2, connecting strips 201, fixed rings 202, connecting rings 203, and relief frames 204. The reinforcing ribs 2 are installed on the outside of the support bag 1, and both ends of the reinforcing ribs 2 extend to the upper and lower sides of the support bag 1. The relief frame 204 is installed on the inner wall of the connecting ring 203. The connecting strip 201 is installed on the outside of the connecting ring 203. The end of the connecting strip 201 away from the connecting ring 203 is installed on the upper end of the fixed ring 202, and the connecting ring 203, the relief frame 204, the connecting ring 203, and the fixed ring 202 are all installed on the outer surface of the support bag 1.

[0033] The injection structure includes an injection slot 3 and a sealing head 301 . The sealing head 301 is threadedly connected to the injection slot 3 . The injection slot 3 is located in the middle of one side of the support bag 1 and is communicated with the interior of the support bag 1 .

[0034] When the device is in use, first, water is poured into the support bag 1 through the injection slot 3 under the guidance of the injection slot 3, and then the sealing head 301 is rotated to close the injection slot 3 to ensure the sealing of the support bag 1 when in use. Secondly, when the device is pressed, the relief frame 204 in the middle will drive the connecting ring 203 to shrink. When the connecting ring 203 shrinks, the fixing ring 202 shrinks at the same time under the transmission of the tension by the connecting strip 201. At the same time, under the connection between the reinforcing rib 2 and the fixing ring 202, the fixing ring 202 is fixed to a certain extent, achieving the effect of supporting and resisting the pressure. Then, under the synchronous support of the water body inside the support bag 1, the pressure on the device is relieved and dispersed, so that under the simultaneous support of the pressure-resistant structure and the water inside the support bag 1, the pressure is dispersed from the middle part of the device, thereby improving the pressure resistance of the middle part of the device and the overall device, thereby improving its safety during use.

[0035] Figure 1 and Figure 2 Shown is a schematic diagram of the three-dimensional structure of a compression-resistant structure as a specific embodiment of the utility model. Figure 1 and Figure 2 In the figure, the connecting ring 203 is located in the middle of the upper end of the support bag 1, and there are at least two connecting rings 203, and the two connecting rings 203 are located on opposite sides of the support bag 1, and the connection methods of the two connecting rings 203 are consistent.

[0036] Under the simultaneous action of the pressure-resistant structures on both sides of the support bag 1, when one side of the support bag 1 is subjected to pressure, the pressure-resistant structures on both sides provide support at the same time, thereby providing double support for the pressure exerted on the device, thereby further improving the overall pressure-resistant effect of the device.

[0037] Figure 3 What is shown is a structural schematic diagram of a specific embodiment of the utility model. Figure 3 In the embodiment, the two fixing rings 202 are both located outside the support bag 1 , and the fixing rings 202 are fixedly connected to a plurality of reinforcing ribs 2 , and the connecting strip 201 is located between the two reinforcing ribs 2 .

[0038] The connecting strip 201 is located at one end of the support bag 1 and at the side of the support bag 1 , and the junction between the support bag 1 and the reinforcing rib 2 is located at the corner of the support bag 1 .

[0039] The two fixing rings 202 are both set on the outside of the support bag 1, so that when the pressure-resistant structure on one side is under pressure, the pressure-resistant structure on the other side can quickly share and relieve the pressure under the transmission of the tension of the support bag 1 itself and the simultaneous connection of the two fixing rings 202 and the reinforcing ribs 2, thereby further improving the overall pressure resistance of the device. In addition, by setting the connecting strips 201 and the reinforcing ribs 2 at the corners of the support bag 1, it is convenient to focus on protecting the side of the support bag 1 to prevent its corners from being broken and damaged. In addition, by connecting the fixing ring 202 and the reinforcing ribs 2, the two can support each other, so that the device can provide pressure buffering from multiple angles and ensure the overall stability of the device when in use.

[0040] Figure 4 What is shown is a structural schematic diagram of a specific embodiment of the utility model. Figure 4 In the figure, both ends of the support bag 1 are round, and the support bag 1 itself is transparent.

[0041] By setting the support bag 1 as a whole to be cylindrical, the contact area of the device during use is increased while the water volume remains unchanged. While supporting the pressure-resistant structure, the pressure on the support bag 1 is dispersed while increasing the contact area of the device, thereby ensuring the compressive strength of the device. Its cross-section is circular, and with the setting of multiple connecting strips 201, it has a certain concave and convex shape, which is convenient for placing and taking the device.

[0042] Figure 3 Shown is a schematic diagram of a material injection structure as a specific embodiment of the utility model. Figure 3 In the embodiment, a support groove is provided at one end of the sealing head 301 away from the injection groove 3, and a cross shape is formed between the support grooves.

[0043] By rotating the cross shape inside the sealing head 301, the rotation of the sealing head 301 is facilitated, and the injection groove 3 is set inside the support bag 1, so that the outer side of the support bag 1 is smooth and not protruding, which is convenient for actual use experience and prevents leakage caused by accidental touch.

[0044] Working principle: First, water is poured into the support bag 1 through the injection slot 3, and then the sealing head 301 is rotated to close the injection slot 3. When the device is pressed, the relief frame 204 in the middle will drive the connecting ring 203 to shrink. When the connecting ring 203 shrinks, the fixing ring 202 shrinks at the same time. At the same time, under the connection between the reinforcing rib 2 and the fixing ring 202, the fixing ring 202 is fixed to a certain extent, so as to achieve the effect of supporting and resisting the pressure. Under the tension transmission of the support bag 1 itself and the simultaneous connection of the two fixing rings 202 and the reinforcing rib 2, the pressure-resistant structure on the other side can quickly share and relieve the pressure. Under the transmission of the tension by the connecting strip 201 and then under the synchronous support of the water body inside the support bag 1, the pressure on the device is relieved and dispersed, thereby improving the pressure resistance of the device.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
