[0035] In order to better understand the above technical solutions, the exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present application can be more clearly and thoroughly understood, and the scope of the present application can be fully conveyed to those skilled in the art.
[0036] As shown in Figure 1 and Figure 2 According to the air bag type dressing device provided by the embodiments of the present application, the air bag 100, the medicine layer 200, the connecting tube 300 and the inflation assembly 400 are provided.
[0037] The air bag type dressing device provided by the embodiments of the present application comprises an air bag 100, a medicine layer 200, a connecting tube 300 and an inflation assembly 400 , The medicine layer 200 is arranged on the outer wall surface of the air bag 100. Exemplarily, the air bag 100 is an air bag capable of being elastically deformed. In use, the air bag 100 is inserted into a hole, the inflation assembly 400 inflates the air bag 100 through the connecting tube 300, the internal pressure of the air bag 100 is changed, and when the internal pressure of the air bag 100 is increased, the air bag 100 expands the hole. At this time, the air bag 100 makes the medicine layer 200 contact with a wound surface in the hole, so as to realize the operation of dressing the wound surface in the hole, greatly reduce the operation difficulty, and improve the comfort of the patient.
[0038] Exemplarily, the medicine layer 200 can be made of a material with strong adsorption and not easy to be damaged (such as a material corresponding to a wound on a band-aid), and the filling medicine is cold compressing, anti-inflammatory, pain relieving, hemostatic and other medicine.
[0039] As shown in Figure 1 and Figure 2 In some examples, the air bag dressing device further comprises a flaring assembly 500 slidingly mounted on the connecting pipe 300 for flaring the hole.
[0040] The air bag dressing device further comprises a flaring assembly 500 slidingly mounted on the connecting pipe 300. The flaring assembly 500 can stably slide on the connecting pipe 300 and is mainly used for flaring the hole. In actual application, when the hole needs to be dressed, the air bag 100 is first inserted into the hole, and then the flaring assembly 500 is slid to gradually approach the edge of the hole. During the process of approaching the edge of the hole, the flaring assembly 500 gradually flares the hole, so that the diameter of the hole is increased, thereby providing better conditions for the smooth entry and flaring of the air bag 100.
[0041] The flaring effect of the flaring assembly 500 can effectively reduce the operation difficulty. In the traditional dressing method, some complex tools and methods are often used to flare the hole, which has a large operation difficulty and is easy to cause secondary injury to the patient. The air bag dressing device in the embodiment of the present application can easily flare the hole through the sliding flaring effect of the flaring assembly 500, thereby greatly reducing the operation difficulty and improving the safety and reliability of the operation.
[0042] Meanwhile, the flaring effect of the flaring assembly 500 can also improve the comfort of the patient. During the process of flaring the hole, the flaring assembly 500 can uniformly apply force to avoid discomfort caused by excessive local force to the patient. Moreover, the material of the flaring assembly 500 can be selected to be relatively soft, which will not cause obvious discomfort when contacting the skin of the patient, thereby improving the comfort of the patient during the treatment process.
[0043] For example, the flaring assembly 500 can be designed to be adjustable in size to adapt to holes of different sizes. The surface of the flaring assembly 500 can be smoothed to reduce friction with the skin and further improve the comfort of the patient.
[0044] As shown in Figure 1 and Figure 2 In some examples, the flaring assembly 500 comprises a flaring body 510 coaxially slidingly mounted on the connecting pipe 300, and a mounting slot 501 arranged along the axis of the flaring body 510 for detachably coaxially mounting the flaring body 510 on the connecting pipe 300.
[0045] In the technical solution, the flared assembly 500 comprises a flaring body 510 coaxially and slidably mounted on the connecting tube 300. The flaring body 510 is shaped and sized to match the connecting tube 300, ensuring coaxial and slidable mounting. The mounting slot 501 is arranged along the axis of the flaring body 510 and is used to detachably mount the flaring body 510 coaxially on the connecting tube 300. Through the mounting slot 501, the flaring body 510 can be easily detached and mounted, greatly improving the convenience of the air bag dressing device. When the flaring body 510 needs to be mounted, the mounting slot 501 is aligned with the connecting tube 300, and then the flaring body 510 is sleeved on the connecting tube 300 by a suitable method, and the coaxial mounting is realized. When the flaring body 510 needs to be detached, the flaring body 510 is removed from the connecting tube 300 along the mounting slot 501.
[0046] The width of the mounting slot 501 is moderate, which can ensure that the flaring body 510 can be smoothly sleeved on the connecting tube 300, and will not cause the flaring body 510 to loosen or fall off during use. For example, the flaring body 510 can be made of elastic material.
[0047] As shown in Figure 1 and Figure 2 In some examples, the flaring body 510 comprises a plurality of cylinders connected coaxially in sequence, and the diameter of the cylinder gradually increases in the direction from the air bag 100 to the inflation assembly 400.
[0048] In the technical solution, the diameter of the cylinder gradually increases in the direction from the air bag 100 to the inflation assembly 400. When the flaring body 510 is working, the smaller diameter cylinder enters the hole first, and as it advances in the direction of the inflation assembly 400, the gradually increasing diameter can gradually and uniformly expand the hole. This gradual expansion method can effectively avoid damage to the surrounding tissue caused by sudden and excessive expansion, greatly improving the safety and reliability of the operation.
[0049] The design of the cylinder with gradually increasing diameter can also better adapt to holes of different sizes and shapes. For smaller holes, the initial smaller diameter cylinder can easily enter, and for larger holes, the subsequent larger diameter cylinder can provide sufficient expansion force to ensure that the dressing device can be applied to various clinical situations.
[0050] For example, the number of cylinders can be adjusted according to actual needs to meet different degrees of expansion requirements. The length and diameter ratio of each cylinder can also be optimized to achieve the best expansion effect and operational convenience. In addition, the material of the cylinder can also be specially treated according to different application scenarios, such as adding an antibacterial coating or using biocompatible materials, to improve the safety and applicability of the dressing device.
[0051] As shown in Figure 1 and Figure 2 In some examples, the inflation assembly 400 includes an inflation bag 410 in communication with the end of the connecting tube 300 away from the air bag 100, a first one-way valve 420 disposed on the inflation bag 410 for allowing external gas to flow in one direction into the interior of the inflation bag 410, and a second one-way valve 430 disposed on the inflation bag 410 for allowing the inflation bag 410 to flow in one direction into the interior of the air bag 100.
[0052] In this technical solution, the inflation assembly 400 includes an inflation bag 410 in communication with the end of the connecting tube 300 away from the air bag 100, and the inflation bag 410 has good elasticity and durability, which can withstand repeated compression and inflation operations without being easily damaged. The shape of the inflation bag 410 is usually designed to be easy to hold and operate, such as an oval or a circle, to facilitate the user to perform the inflation operation. The connection part between the inflation bag 410 and the connecting tube 300 adopts a tight sealing design to ensure that there is no gas leakage during the inflation process, thereby ensuring that the air bag 100 can be inflated smoothly and reach the required internal pressure.
[0053] The first one-way valve 420 is disposed on the inflation bag 410 for allowing external gas to flow in one direction into the interior of the inflation bag 410. When the user squeezes the inflation bag 410, external gas can smoothly enter the interior of the inflation bag 410 through the first one-way valve 420, and during the rebounding process of the inflation bag 410, the first one-way valve 420 can effectively prevent the gas inside the inflation bag 410 from flowing back to the external environment.
[0054] The second one-way valve 430, disposed on the air bladder 410, is used to allow gas inside the air bladder 410 to flow unidirectionally into the air bladder 100. It ensures the unidirectional flow of gas from the air bladder 410 to the air bladder 100, preventing gas inside the air bladder 100 from flowing back into the air bladder 410 when not needed. The working principle of the second one-way valve 430 is similar to that of the first one-way valve 420. In practical applications, the synergistic effect of the first one-way valve 420 and the second one-way valve 430 makes the inflation process of the air bladder dressing device safer, more reliable, and more efficient. They effectively prevent gas leakage and backflow, ensuring that the air bladder 100 can obtain a stable internal pressure, thereby enabling effective dressing operations on wounds within openings.
[0055] like Figure 1 and Figure 2 As shown, in some instances, the inflation assembly 400 further includes a switch valve 440, which is disposed on the inflation bladder 410 and located on the side of the second one-way valve 430 near the air bladder 100, for controlling the connection or disconnection of the interior and exterior air of the air bladder 100.
[0056] In this technical solution, the inflation assembly 400 further includes a switching valve 440, which is disposed on the inflation bladder 410 and located on the side of the second one-way valve 430 near the air bladder 100. The switching valve 440 being located on the side of the second one-way valve 430 near the air bladder 100 allows for effective control of the connection or disconnection between the air inside the air bladder 100 and the external air.
[0057] When the switch valve 440 is closed, it completely blocks the flow of air between the inside and outside of the airbag 100. This is crucial for maintaining a stable air pressure inside the airbag 100. In certain situations, such as when the airbag needs to be kept inflated for an extended period to ensure the dressing's effectiveness, closing the switch valve 440 prevents gas leakage from inside the airbag 100, thus ensuring the dressing device can function continuously and stably. Furthermore, the closed switch valve 440 also prevents external impurities, dust, or bacteria from entering the airbag 100, thereby maintaining the cleanliness and hygiene inside the airbag.
[0058] When it is necessary to deflate the airbag 100 or adjust its pressure, the user can easily open the switch valve 440. At this time, the gas inside the airbag 100 can be released by allowing the air to flow through the switch valve 440 to the outside air. This controllable deflation process can be adjusted according to actual needs to achieve a suitable pressure level. For example, in some cases, it may be necessary to gradually reduce the airbag pressure to suit the patient's comfort or treatment needs. By precisely controlling the opening degree of the switch valve 440, fine-tuning of the deflation rate and pressure changes can be achieved.
