Description

Technical Field

[0001] This invention belongs to the technical field of postoperative compression hemostasis equipment, and in particular relates to a protective device for postoperative compression hemostasis in the thoracic cavity. Background Technology

[0002] Postoperative compression hemostasis is necessary after thoracic surgery, primarily due to the inherent characteristics of the procedure: the thoracic incision is deep and involves densely vascularized areas such as the chest wall and hilum, while the thoracic cavity is under negative pressure, making the wound prone to continuous bleeding. Without intervention, this could lead to excessive blood loss. Furthermore, the rise and fall of the chest during breathing and activity can pull on the incision, potentially increasing the risk of infection and thoracic complications. Compression counteracts this negative pressure with external force, slowing the rate of vascular bleeding, promoting platelet aggregation and clot formation, effectively controlling bleeding and preventing shock. It also stabilizes the tissues around the incision, reducing traction and preventing wound dehiscence. Additionally, it isolates external dust and bacteria, lowering the probability of infection. Moreover, stable compression helps maintain pressure balance within the thoracic cavity, reducing problems such as pneumothorax and hemothorax caused by bleeding and effusion, creating a stable environment for lung function recovery. This is a crucial step in ensuring postoperative safety and promoting recovery. For example, patent CN219594706U discloses a postoperative hemostatic compression device.

[0003] Currently, the compression hemostasis protection devices used after thoracic surgery have the following problems: First, the lack of visual monitoring of the compression force requires the nursing staff to rely on their experience to apply pressure to the surgical incision, resulting in a serious lack of precision in compression hemostasis. Furthermore, the required pressure level for chest surgical incisions varies among different patients, and traditional compression hemostasis protection devices are difficult to meet individualized compression needs, which can easily lead to problems of excessive or insufficient pressure. Excessive pressure can cause secondary damage to the postoperative chest incision, seriously affecting the safety and comfort of the patient's recovery, while insufficient pressure will reduce the hemostasis and recovery effect of the incision. Secondly, when patients forget about the postoperative incision and make significant adjustments to their posture (such as getting up or taking items from the bedside table), the large range of motion in a short period of time can easily cause the tissues on both sides of the postoperative thoracic incision to be stretched and expanded. This can not only cause pain from the incision being pulled, but may also cause the incision to bleed again after initial hemostasis. This not only affects the reliability of the postoperative compression hemostasis protection device, but also has an adverse effect on the patient's recovery after thoracic surgery.

[0004] Therefore, we propose a postoperative compression hemostasis protection device for the thoracic cavity to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a postoperative compression hemostasis protection device for the thoracic cavity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a postoperative compression hemostasis protection device for thoracic surgery, comprising a compression cloth, wherein a through hole is provided on the upper surface of the compression cloth, and a protective cover is fixedly connected to the wall of the through hole; two symmetrically distributed arc-shaped slots are provided on the outer wall of the bottom end of the protective cover; an elastic sealing rubber cover is fixedly sleeved on the bottom end of the protective cover; and a compression hemostasis mechanism is fixedly connected to the inner wall of the protective cover. The top of the compression hemostasis mechanism is fixedly connected to a sealing sleeve, and an air supply mechanism is provided on the outside of the sealing sleeve. The sealing sleeve is fixedly connected to a hemostatic pressure visualization mechanism on the side away from the protective cover. The outer wall of the compression cloth is fixedly connected to a postoperative incision protection mechanism; The outer walls of both ends of the compression fabric are stitched together with a limiting mechanism.

[0007] In the above-mentioned postoperative compression hemostasis protection device for the thoracic cavity, the compression hemostasis mechanism includes an inflatable rubber air cover fixedly connected to the inner wall of the protective cover. Two first needle-hair hook and loop fasteners are fixedly connected to the outer wall of the inflatable rubber air cover. A first cotton hook and loop fastener is connected to the outer wall of the two first needle-hair hook and loop fasteners. A moisture-absorbing component is fixedly connected to the outer wall of the two first cotton hook and loop fasteners. A sterile gauze layer is bonded to the outer wall of the moisture-absorbing component by medical-grade adhesive.

[0008] In the above-mentioned postoperative compression hemostasis protection device for thoracic surgery, the moisture-absorbing component includes a hollow gauze cover, the interior of which is filled with a layer of medical-grade absorbent resin particles.

[0009] In the above-mentioned postoperative compression hemostasis protection device for thoracic surgery, the air supply mechanism includes a first trachea and a second trachea. Both the first and second tracheas are located inside the sealing sleeve. The air inlet ends of the first and second tracheas pass through the outer wall of the sealing sleeve and are fixedly connected to a three-way reversing valve. The air inlet end of the three-way reversing valve is fixedly connected to a first air inlet check valve. The air inlet end of the first air inlet check valve is fixedly connected to a reset rubber airbag. The air inlet of the reset rubber airbag is fixedly connected to a second air inlet check valve. The air outlet end of the first trachea passes through the side end of the sealing sleeve and communicates with the internal cavity of the inflatable rubber air cover. The air outlet end of the second trachea communicates with the internal cavity of the elastic sealing rubber cover. The sealing sleeve, the compression cloth, and the protective cover all have sealing through holes that cooperate with the air outlet end of the second trachea. The outer walls of the air inlet ends of the first and second tracheas are fixedly connected to pressure relief valves.

[0010] In the aforementioned post-thoracic compression hemostasis protection device, the visual hemostasis compression force mechanism includes a hollow block fixedly sleeved to the outer wall of the side end of the sealing sleeve. A controller and a power supply are fixedly connected to the inner wall of the hollow block. A rectangular through hole is opened on the outer wall of the hollow block, and a touch screen display panel is fixedly connected to the wall of the rectangular through hole. A piezoelectric film is fixedly connected to the outer wall of the expanding rubber air cover. A conductive wire is electrically connected to the receiving end of the piezoelectric film. A sheath is fixedly sleeved on the outer wall of the conductive wire. The bottom end of the sheath is fixedly inserted through the bottom end of the expanding rubber air cover. The top end of the sheath is fixedly connected to the inner wall of the sealing sleeve. A fixed through hole that matches the outer wall of the first trachea is opened on the outer wall of the sheath. The end of the conductive wire away from the piezoelectric film is electrically connected to the input end of the controller.

[0011] In the above-mentioned postoperative compression hemostasis protection device for the thoracic cavity, a soft rope is fixedly connected to the outer wall of the hollow block, and a hook is fixedly connected to the outer wall of the soft rope.

[0012] In the above-mentioned postoperative compression hemostasis protection device for thoracic surgery, the postoperative incision protection mechanism includes a connecting rope fixedly connected to the outer wall of the compression cloth, a first elastic band fixedly connected to the connecting end of the connecting rope, a first soft collar fixedly connected to one end of the first elastic band, a limiting ring sleeved on the outer side of the first elastic band, a threaded hole opened on the outer wall of the limiting ring, and a limiting bolt threadedly connected to the wall of the threaded hole, and a second soft collar fixedly connected to the outer wall of the limiting ring.

[0013] In the above-mentioned postoperative compression hemostasis protection device for the thoracic cavity, the limiting mechanism includes two second elastic bands and a third elastic band. The side ends of the two second elastic bands are fixedly sewn with second needle-hair hook and loop fasteners, and the side ends of the two third elastic bands are fixedly sewn with second cotton hook and loop fasteners that cooperate with the second needle-hair hook and loop fasteners.

[0014] Compared with existing technologies, the advantages of a postoperative compression hemostasis protection device for the thoracic cavity are: 1. The postoperative incision protection device, when a patient requires compression hemostasis after thoracic surgery, is first put on by the nursing staff. The first and second soft loops are located under the patient's armpits on both sides. The device helps to bring the patient's shoulders together, relaxing the skin and muscles of the chest, ensuring that the body tissues at the surgical incision site are not pulled. This provides a stable healing environment for the incision, facilitating recovery. If the patient forgets the postoperative incision care instructions and makes a large-scale postoperative adjustment with their arms outstretched, the resistance of the first elastic band will promptly remind and correct the patient, preventing the tissues at the incision site from being pulled by large movements and avoiding severe pain. It also prevents secondary bleeding from the initially hemostatic incision, effectively improving the reliability of the postoperative compression hemostasis device and ensuring the patient's recovery after thoracic surgery.

[0015] 2. Through the established compression hemostasis mechanism, limiting mechanism, air supply mechanism, and visual hemostasis pressure mechanism, after the postoperative incision protection device is donned, nursing staff first disinfect and protect the device by wiping the inner wall of the protective shield and the elastic sealing rubber cover with alcohol. Then, the postoperative hemostatic agent is evenly applied to the sterile gauze layer, which is then precisely covered over the postoperative thoracic incision. Simultaneously, the limiting mechanism, compression hemostasis mechanism, and air supply mechanism are used to perform postoperative thoracic compression hemostasis protection. During the compression hemostasis process, the visual hemostasis pressure mechanism allows for real-time monitoring of the pressure, precisely controlling the pressure applied to the postoperative thoracic incision to prevent excessive pressure leading to local tissue ischemia or insufficient pressure resulting in ineffective hemostasis. This mechanism enables the device to visualize postoperative thoracic compression pressure and precisely control the pressure, improving the effectiveness of postoperative thoracic compression hemostasis and rehabilitation, preventing secondary injury, and enhancing the safety and comfort of the patient's recovery.

[0016] 3. Through the designed moisture-absorbing components, elastic sealing rubber cover, and air supply mechanism, after the hemostasis and compression care of the postoperative thoracic incision is completed, the nursing staff switches the air outlet direction of the three-way reversing valve and supplies air into the elastic sealing rubber cover through the air supply mechanism. After the elastic sealing rubber cover is inflated, it fits tightly against the patient's skin, achieving a seal and isolation of the postoperative thoracic incision, preventing bacteria from the external environment from invading the incision and causing infection. If there is blood and body fluid seepage at the postoperative thoracic incision site, the sterile gauze layer can initially absorb the seepage, and the moisture-absorbing components further enhance the seepage absorption capacity, effectively preventing seepage from overflowing and ensuring that the skin and surrounding tissues at the postoperative thoracic incision site are dry. At the same time, maintaining the dryness of the incision site can reduce skin maceration and discomfort caused by prolonged seepage retention, and can also reduce the risk of bacterial growth in the seepage, maintaining a stable microenvironment for incision healing, further improving the device's protective ability for the postoperative thoracic incision, reducing the probability of incision infection, improving the reliability of the device, and ensuring the recovery effect of the postoperative thoracic incision.

The air supply mechanism 6 includes a first air pipe 61 and a second air pipe 62. Both the first air pipe 61 and the second air pipe 62 are located inside the sealing sleeve 10. The air inlet ends of both the first air pipe 61 and the second air pipe 62 pass through the outer wall of the sealing sleeve 10 and are jointly fixedly connected to a three-way reversing valve 63. The air inlet end of the three-way reversing valve 63 is fixedly connected to a first air inlet check valve 64. The air inlet end of the first air inlet check valve 64 is fixedly connected to... The reset rubber airbag 65 has an air inlet that is fixedly connected to a second air inlet one-way valve 66. The air outlet of the first air pipe 61 passes through the side end of the sealing sleeve 10 and is connected to the internal cavity of the expansion rubber air cover 41. The air outlet of the second air pipe 62 is connected to the internal cavity of the elastic sealing rubber cover 11. The outer walls of the sealing sleeve 10, the compression cloth 1, and the protective cover 2 are all provided with sealing through holes that match the air outlet of the second air pipe 62. The outer walls of the air inlets of the first air pipe 61 and the second air pipe 62 are both fixedly connected to a pressure relief valve 67.

[0022] A hemostatic pressure visualization mechanism 7 is fixedly connected to the side of the sealing sleeve 10 away from the protective cover 2. The hemostatic pressure visualization mechanism 7 includes a hollow block 71 fixedly sleeved to the outer wall of the side end of the sealing sleeve 10. A soft rope 12 is fixedly connected to the outer wall of the hollow block 71, and a hook 13 is fixedly connected to the outer wall of the soft rope 12. The soft rope 12 and the hook 13 facilitate the carrying of the hollow block 71 after the patient gets up. A controller 72 and a power supply 73 are fixedly connected to the inner wall of the hollow block 71. A rectangular through hole is opened on the outer wall of the hollow block 71, and a touch screen display panel 74 is fixedly connected to the wall of the rectangular through hole. A piezoelectric film 75 is fixedly connected to the outer wall of the expanding rubber gas cover 41. The piezoelectric film 75 is connected to... The electrical terminal is connected by a conductive wire 76, and a sheath 77 is fixedly sleeved on the outer wall of the conductive wire 76. The bottom end of the sheath 77 is fixedly inserted through the bottom end of the expansion rubber gas cover 41, and the top end of the sheath 77 is fixedly connected to the inner wall of the sealing sleeve 10.

The touch screen display panel 74 is electrically connected to the output end of the controller 72 through a wire. The power supply 73 can provide a stable DC power supply to the electrical components of the entire device. The controller 72 is an 80C51 microcontroller. The above-mentioned electrical components and electrical connections are all existing technologies and will not be described in detail here.

[0023] The outer wall of the compression cloth 1 is fixedly connected to a postoperative incision protection mechanism 8. The postoperative incision protection mechanism 8 includes a connecting rope 81 fixedly connected to the outer wall of the compression cloth 1. The connecting end of the connecting rope 81 is fixedly connected to a first elastic band 82. One end of the first elastic band 82 is fixedly connected to a first soft collar 83. A limiting ring 84 is sleeved on the outer side of the first elastic band 82. The outer wall of the limiting ring 84 has a threaded hole, and the hole wall of the threaded hole is threadedly connected to a limiting bolt 85. The outer wall of the limiting ring 84 is fixedly connected to a second soft collar 86.

[0024] The outer walls of both ends of the compression fabric 1 are jointly sewn together with a limiting mechanism 9. The limiting mechanism 9 includes two second elastic bands 91 and a third elastic band 92. The side ends of the two second elastic bands 91 are fixedly sewn with second needle hair hook and loop fasteners 93, and the side ends of the two third elastic bands 92 are fixedly sewn with second cotton wool hook and loop fasteners 94 that cooperate with the second needle hair hook and loop fasteners 93. This mechanism can improve the stability of the device in use.

[0025] The operating principle of this invention is described as follows: When a patient needs compression hemostasis and protection after thoracic surgery, the nurse first places the first soft collar 83 and the second soft collar 86 on the patient's arms on both sides, and moves the first soft collar 83 and the second soft collar 86 to the armpits. The first elastic band 82 is then pulled in the limiting ring 84, causing the patient's shoulders to come together. After the patient's shoulders come together, the skin and muscles on the patient's chest will also relax, ensuring that the body tissues at the surgical incision site after thoracic surgery will not be pulled. The body tissues on both sides of the surgical incision site will come together, thereby providing a stable healing environment for the postoperative incision tissues and facilitating the recovery and healing of the postoperative incision tissues. Then, the limiting bolt 85 is rotated to squeeze the adjusted first elastic band 82, thereby achieving the purpose of limiting the first elastic band 82. In addition, when patients forget the postoperative incision care requirements and make significant postural adjustments (such as getting up or taking items from the bedside table), they often spread their arms to assist in maintaining stability. However, at the moment the arms are spread, the first soft loop 83 or the second soft loop 86 will pull the first elastic band 82. Then, the tensile resistance of the first elastic band 82 will promptly remind the patient and correct the extent of the postoperative adjustment, preventing the tissues on both sides of the thoracic incision from being pulled by large movements and avoiding the resulting severe pain. At the same time, it prevents secondary bleeding from the incision that has been initially hemostatic after surgery, effectively improving the reliability of the postoperative compression hemostasis protection device and ensuring the recovery effect of patients after thoracic surgery. After the postoperative incision protection device 8 is put on, the nursing staff first disinfects and protects the inner wall of the protective cover 2 and the elastic sealing rubber cover 11 by wiping with alcohol. Then, the postoperative hemostatic drug is evenly applied to the sterile gauze layer 44. After that, the sterile gauze layer 44 is precisely covered on the incision site after the thoracic surgery. At the same time, the protective cover 2 is pressed tightly against the skin tissue of the patient at the postoperative incision site. Then, the second elastic band 91 and the third elastic band 92 are stretched appropriately and wrapped around the patient's limbs, so that the second cotton Velcro patch 94 and the second needle Velcro patch 93 are stuck together. Finally, the protective cover 2 is stably positioned on the patient's body. When the postoperative incision site is located on the patient's waist, the arc-shaped slot 3 of the protective cover 2 can be stably locked on the patient's waist, further improving the stability of the protective cover 2's positioning. Afterwards, the nursing staff repeatedly presses the reset rubber cuff 65, allowing the air inside the reset rubber cuff 65 to enter the first trachea 61 through the first air inlet one-way valve 64 and the three-way reversing valve 63. When the reset rubber cuff 65 is released and it is reset and inflated, the second air inlet one-way valve 66 will draw outside air into the reset rubber cuff 65. This cycle continues, and the air is continuously discharged through the first trachea 61 into the inflatable rubber air mask 41. The inflatable rubber air mask 41 pushes the moisture-absorbing component 5 and the sterile gauze layer 44 to compress the postoperative incision in the thoracic cavity, thereby achieving compression hemostasis. During the inflation and compression process of the expanding rubber air shield 41, the piezoelectric diaphragm 75 experiences voltage changes under pressure (consistent with the characteristics of the piezoelectric effect). That is, the greater the pressure applied to the piezoelectric diaphragm 75, the stronger the voltage signal it generates. The controller 72 then converts the voltage signal from the piezoelectric diaphragm 75 into a pressure value, which is displayed on the touchscreen display panel 74. This allows nursing staff to directly monitor the real-time pressure and precisely control the pressure applied to the patient's post-thoracic incision for hemostasis. This avoids situations where excessive pressure leads to local tissue ischemia or insufficient pressure fails to achieve effective hemostasis. Appropriate pressure maintains effective hemostasis while also... This device ensures normal blood supply to the tissues surrounding the incision, providing sufficient oxygen and nutrients for tissue repair. It then reduces bleeding and fluid accumulation at the incision site, decreases local swelling, and creates a clean environment for incision healing. Finally, it uses stable pressure to fix the tissues around the incision, reducing traction on the incision from limb movement, lowering incision tension, and promoting the orderly growth of granulation tissue and epithelial tissue. This device enables the device to visualize the pressure applied after thoracic surgery and has the ability to precisely control the pressure, improving the effectiveness of postoperative compression hemostasis and rehabilitation, avoiding secondary injury, and improving the safety and comfort of patient recovery. After the thoracic incision hemostasis and compression care is completed, the nursing staff switches the air outlet direction of the three-way reversing valve 63 and continues to repeatedly press the reset rubber bladder 65. At this time, the reset rubber bladder 65 delivers air into the elastic sealing rubber cover 11 through the first air inlet one-way valve 64, the second trachea 62 and the second air inlet one-way valve 66. After the elastic sealing rubber cover 11 is inflated, it fits tightly against the patient's skin, achieving a seal and isolation of the thoracic incision, preventing bacteria from the external environment from invading the incision and causing infection. At the same time, the seal and isolation can provide physical protection for the thoracic incision and create a continuously suitable microenvironment for skin tissue repair. In addition, if there is blood and body fluid exudation at the incision site after thoracic surgery, the sterile gauze layer 44 can initially absorb the exudate, and the moisture-absorbing component 5 further enhances the fluid absorption capacity. In particular, the medical-grade absorbent resin particle layer 52 can quickly absorb and firmly lock in the water through high molecular polymerization (the fluid absorption capacity can reach dozens of times its own weight), effectively preventing the exudate from overflowing and ensuring that the skin and surrounding tissues at the incision site after thoracic surgery are dry. At the same time, keeping the incision site dry can reduce skin maceration and discomfort caused by prolonged retention of exudate, and can also reduce the risk of bacterial growth in the exudate, maintaining a stable microenvironment for incision healing, further improving the device's protective ability for thoracic surgery incisions, reducing the probability of incision infection, improving the reliability of the device, and ensuring the recovery effect of thoracic surgery incisions.
