Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, specifically a pressure care belt for postoperative wound care in cardiac surgery. Background Technology

[0002] In the field of cardiac surgery, proper postoperative wound care plays a crucial role in patient recovery. Cardiac surgery typically involves operations on the heart and surrounding major blood vessels, resulting in large and deep wounds. Due to the continuous beating of the heart and the influence of blood circulation, the wound faces numerous challenges, including bleeding, effusion, and slow healing. Traditional postoperative wound care often involves wrapping the wound with ordinary bandages. While simple and easy to perform, ordinary bandages cannot provide precise and stable pressure to the wound. Medical staff rely solely on experience to manually wrap the bandage, making it difficult to accurately control the pressure. This can easily lead to uneven pressure, potentially causing excessive pressure in the wound area, affecting blood circulation, or insufficient pressure, failing to effectively stop bleeding and promote healing.

[0003] In recent years, to improve postoperative wound care in cardiac surgery, some simple pressure devices have emerged. For example, some nursing straps use a single-bladder structure, attempting to achieve pressure through cuff inflation. However, this single-bladder design proves inadequate when faced with complex wound shapes and diverse patient needs. It can only provide overall, single-mode pressure, unable to apply appropriate pressure to different parts of the wound, such as the center and edges. Furthermore, existing pressure nursing straps of this type have significant shortcomings in cuff inflation adjustment. Most only have a simple air inlet, requiring an external air source to fully inflate the cuff at once, making it impossible to individually inflate or deflate specific cuffs as needed during subsequent care, thus failing to meet the pressure requirements of different stages of wound healing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure care belt for postoperative wound care in cardiac surgery.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A pressure care belt for postoperative cardiac surgery wounds includes a pressure plate and straps disposed on both sides of the pressure plate, wherein the pressure plate is provided with a plurality of pressure airbags.

[0007] The pressure plate has an inflation port for inflating the pressurized airbag on its side, and an air inlet is rotatably sleeved on the outside of the inflation port. The inflation port and the air inlet are concentric annular structures.

[0008] The inflation port is provided with several sets of inflation holes, and the inflation holes are interconnected with the pressurized airbag through an air supply pipe; the bottom of the air inlet is provided with a set of air inlets corresponding to the inflation holes.

[0009] An annular positioning seat is fixed in the middle of the air inlet, and a wave-shaped guide groove is provided on the inner side of the positioning seat; a guide seat that slides along its axial direction is installed on the air inlet, and the guide seat is connected to the positioning seat by a return spring; a guide pin that is stuck in the guide groove is provided on the side of the guide seat.

[0010] When the guide pin is engaged at the crest or trough of the guide groove, the air inlet is aligned with one of the sets of inflation holes.

[0011] Preferably, the number of inflation holes is one more than the number of pressurized airbags, and the extra inflation hole is provided with a sealing plug.

[0012] Preferably, the number of wave crests in the guide groove and the number of guide pins are the same as the number of air holes.

[0013] Preferably, a receiving groove is provided at the middle position of the bottom of the air inlet, and a regular hexagonal limiting rod is provided in the receiving groove. A limiting hole is provided on the guide seat; the limiting rod passes through the limiting hole.

[0014] Preferably, the outer side of the inflation port is provided with a number of indicator plates corresponding to the inflation holes, and the air inlet is provided with an indicator strip facing the inflation port, and the indicator strip corresponds to the air inlet.

[0015] Preferably, an annular limiting band is provided on the outer side of the inflation port, and an annular limiting groove is provided on the air inlet, the limiting groove being engaged with the outer side of the limiting band.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting several sets of airbags on the pressure plate, they work together to apply pressure to the wound, ensuring effective hemostasis and promoting healing, without affecting blood circulation due to excessive local pressure;

[0018] 2. By adjusting the state of the inflation port and air inlet, specific airbags can be individually inflated or deflated. Appropriate pressure can be applied to different parts of the wound, such as the center and edge areas, to meet the pressure change requirements of wound healing at different stages and provide a more suitable pressure care plan for the entire wound healing process.

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Example

[0028] like Figure 1 As shown, a pressure care belt for postoperative cardiac surgery wounds mainly consists of a pressure plate 1, straps 12 on both sides of the pressure plate 1, and several sets of pressure airbags 11 mounted on the pressure plate 1. The pressure plate 1 supports the pressure airbags 11 and evenly transmits pressure to the wound site, while the straps 12 on both sides serve to fix the pressure plate 1 in place, securing it to the patient's body. The straps 12 can be made of soft and elastic materials, such as cotton blends, ensuring comfort while adapting to slight swelling changes in the patient's body. Their length can be adjusted using Velcro or buckles to accommodate patients of different body types.

[0029] Please see Figure 2The pressure plate 1 has an inflation port 2 on its side for inflating the pressurized airbag 11. An air inlet 3 is rotatably fitted around the inflation port 2, forming a concentric ring structure. The rotating inflation port 2 and air inlet 3 provide the foundation for subsequent inflation operations. The inflation port 2 has several sets of inflation holes 21, which are interconnected with the pressurized airbag 11 via air delivery pipes, ensuring precise gas delivery to each airbag. The bottom of the air inlet 3 has a set of air inlets 31 corresponding to the inflation ports 21. By rotating the air inlet 3, the air inlets 31 can be aligned with different inflation ports 21, thereby achieving inflation of a specific pressurized airbag 11.

[0030] The number of inflation holes 21 is one more than the number of pressure air bags 11, and the extra inflation hole 21 is equipped with a sealing plug 22; this structure is mainly for use when inflation is not required during use, the inflation hole 21 can be rotated to be aligned with the air bag 11, so as to ensure that the nursing belt can still work normally and not affect the patient's wound care.

[0031] like Figure 4 , Figure 5 As shown, an annular positioning seat 4 is fixed in the middle of the inflation port 2, and a wave-shaped guide groove 41 is provided on the inner side of the positioning seat 4. A guide seat 5 that slides along its axial direction is installed on the air inlet 3. The guide seat 5 is connected to the positioning seat 4 by a return spring 53. A guide pin 51 that is stuck in the guide groove 41 is provided on the side of the guide seat 5. When the air inlet 3 is rotated, the guide seat 5 will rotate with it, thereby driving the guide pin 51 on the side to move along the guide groove 41. Since the guide groove 41 is wave-shaped, the guide pin 51 will drive the guide seat 5 to slide axially. This axial sliding allows medical staff to clearly perceive the inflation status during operation. When the guide pin 51 is at the crest or trough of the guide groove 41 under the push or pull of the return spring 53 without external force, the air inlet 31 is aligned with one of the sets of inflation holes 21, realizing precise positioning inflation.

[0032] A receiving groove 32 is provided at the middle position of the bottom of the air inlet 3. A regular hexagonal limiting rod 33 is provided in the receiving groove 32. A limiting hole 52 is provided on the guide seat 5. The limiting rod 33 passes through the limiting hole 52 to effectively prevent the air inlet 3 from deviating or shaking during rotation.

[0033] like Figure 3As shown, the outer side of the inflation port 2 is provided with several sets of indicator plates 23 corresponding to the inflation holes 21. The air inlet 3 is provided with an indicator strip 35 facing the inflation port 2, and the indicator strip 35 corresponds to the air inlet 31. During operation, medical staff can quickly determine whether the air inlet 31 is aligned with which inflation hole 21 by observing the relative position of the indicator strip 35 and the indicator plates 23, thereby determining which airbag can be inflated, greatly improving the convenience and accuracy of the inflation operation.

[0034] The number of crests in the guide groove 41 and the number of guide pins 51 are the same as the number of inflation holes 21, so that one crest or trough corresponds to one inflation hole 21, enabling one airbag to be inflated, making the inflation process simpler and the entire inflation system more reliable and durable.

[0035] An annular limiting band 24 is provided on the outer side of the inflation port 2, and an annular limiting groove 34 is provided on the air inlet 3. The limiting groove 34 is engaged with the outer side of the limiting band 24. This restricts the relative displacement between the air inlet 3 and the inflation port 2, allowing them to rotate only and preventing movement in other directions, thus improving the overall stability of the structure.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
