Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a portable negative pressure suction device for treating chronic wounds. Background Art

[0002] Negative pressure suction devices are generally used in wards and are mainly used for medical drainage, sputum removal, sewage and secretion removal, etc. It uses the vacuum working principle to generate negative pressure in the cavity, thereby guiding the liquid in the cavity out to achieve the purpose of sewage purification. In some complex surgical operations, such as plastic surgery, thoracic and abdominal surgery, etc., it is used to promote the healing and rehabilitation of surgical incisions. Therefore, a portable negative pressure suction device for treating chronic wounds is required.

[0003] For example, a portable negative pressure suction device for treating burn wounds with the patent publication number 202211141958.3 includes a device cylinder. An equipment component and a sewage component are arranged in the device cylinder, and a handheld negative pressure suction component is connected outside the device cylinder; the handheld negative pressure suction component includes a fixed tube and a handheld tube. A spherical cover is fixedly connected between the fixed tube and the handheld tube. One end of the handheld tube away from the spherical cover is connected with a rotating tube, and a connecting tube is fixedly connected between the rotating tube and the handheld tube. One end of the rotating tube away from the connecting tube is fixedly connected with a suction cover. The present invention can perform suction debridement treatment on the body wounds of burn patients by setting the handheld negative pressure suction component, and can discharge and collect the debrided dirt through the sewage component. By setting the angle positioning component, negative pressure suction at multiple angles can be achieved, which is convenient for operation and can ensure the stable discharge of dirt, and has a good effect on wound treatment in the burn department.

[0004] However, during the use of the above device, due to the setting of the fixed tube and the rotating tube inside it, during use, due to its large occupied space, it is not convenient to carry when carrying and transporting. At the same time, since the shapes of wounds are mostly irregular, the suction cover directly contacts the wound, which easily affects the stability of the negative pressure and reduces the working efficiency. Therefore, in view of this situation, we propose a more convenient and practical negative pressure suction device to meet the use requirements. Summary of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] For intractable chronic wounds, such as pressure sores, ulcers, diabetic feet, etc., a negative pressure suction device is required. The negative pressure suction device adopts a sealed dressing system, which provides continuous and appropriate negative pressure through a negative pressure pump source, creating a micro negative pressure environment at the wound site, helping to remove wound exudates and reduce edema, while promoting blood circulation and the formation of new blood vessels, and can also stimulate cell proliferation and tissue repair, thereby accelerating the wound healing process. The negative pressure suction device provided by the present invention is specifically used for intractable chronic wounds. When using this device, first, this device has certain requirements for working conditions such as the working environment and hygiene conditions. At the same time, this device can also be used in a relatively narrow space. There needs to be a power supply facility or mobile power source in the site. When using it, at least one medical staff is required to operate. It should be noted that during the use process, this device needs to be cleaned regularly to prevent cross-infection.

[0026] As Figures 1-5 shown, the present invention provides a technical solution: a portable negative pressure suction device for chronic wound treatment, including a drainage mechanism 1. The drainage mechanism 1 includes a fixed frame 101, and a liquid storage bottle 102 is slidably connected to the inner wall of the fixed frame 101. A negative pressure mechanism 2 is arranged on one side of the drainage mechanism 1. The negative pressure mechanism 2 includes a negative pressure suction device 201. A suction pipe 202 is fixedly connected to the center of the top of the negative pressure suction device 201. A wound dressing mechanism 4 is arranged on the side of the drainage mechanism 1 away from the negative pressure mechanism 2. The wound dressing mechanism 4 includes an attraction cover 401.

[0027] It should be noted that during the use process, first, the wound dressing mechanism 4 is attached to the wound surface, and then the negative pressure suction device 201 of the negative pressure mechanism 2 sucks the air in the liquid storage bottle 102 through the suction pipe 202, and sucks the air in the wound through the drainage mechanism 1 and the attraction cover 401 of the wound dressing mechanism 4 to generate negative pressure. The device has a simple structure, occupies a small space, is easy to install and disassemble, and is relatively convenient for cleaning and maintenance. When it needs to be carried and transported, it is convenient to carry.

[0028] As Figure 3As shown in the figure, a fixing ring 103 is fixedly connected to the top of the liquid storage bottle 102. A scale 104 is engraved on one side of the outer wall of the liquid storage bottle 102. A bottle cap 105 is arranged on the top of the liquid storage bottle 102. A through hole is thus opened on the top of the bottle cap 105. An exhaust pipe 106 is fixedly connected inside the through hole. An air inlet pipe 107 is fixedly connected to the side of the bottle cap 105 away from the exhaust pipe 106. A one-way valve 108 is installed at the top of the air inlet pipe 107. Fixing blocks 109 are fixedly connected to both sides of the top of the bottle cap 105. A buckle 110 is rotatably connected to one side of the fixing block 109. An elastic plate 111 is fixedly connected to one side of the fixing frame 101. One end of the one-way valve 108 is fixedly connected to a second connecting hose 3.

[0029] It should be noted that during the use process, first, the fixing frame 101 of the drainage mechanism 1 is hung on a convenient place to carry through the elastic plate 111. Then, manually operate the second connecting hose 3 to connect the drainage mechanism 1 and the wound dressing mechanism 4 through the one-way valve 108 and the air inlet pipe 107. At the same time, the negative pressure aspirator 201 is started to suck the air between the liquid storage bottle 102 and the wound through the exhaust pipe 106 to form a negative pressure. When it is necessary to clean the liquid storage bottle 102, manually toggle the buckle 110 to open under the action of the fixing block 109. The scale 104 facilitates timely viewing of the liquid storage volume in the liquid storage bottle 102. The liquid storage bottle 102 of the drainage mechanism 1 can collect a large amount of liquid, reduce the frequency of replacing the liquid storage device, and facilitate long-term use and management.

[0030] As Figure 4 As shown in the figure, one end of an air suction pipe 202 is slidably connected to a first connecting hose 203. One end of the first connecting hose 203 is connected to one end of the exhaust pipe 106. An installation ring 204 is fixedly connected to one side of the negative pressure aspirator 201. A fixing buckle 205 is arranged at one end of the installation ring 204, and a connection hole 206 is opened at the other end. The connection hole 206 and the fixing buckle 205 are coaxial.

[0031] It should be noted that during the use process, first, the negative pressure aspirator 201 is connected to a convenient place to carry through the installation ring 204. Then, it is fixed through the fixing buckle 205 and the connection hole 206. At the same time, manually operate the first connecting hose 203 to connect the air suction pipe 202 and the exhaust pipe 106. Finally, the negative pressure aspirator 201 is started to perform negative pressure drainage on the drainage mechanism 1 and the wound dressing mechanism 4. The negative pressure mechanism 2 can apply an appropriate negative pressure to the wound to reduce the exposure and excessive stretching of the wound, and provide a suitable environment for wound healing.

The bottom of the upper connection ring 405 is fixedly connected to a telescopic tube 406. One end of the telescopic tube 406 is fixedly connected to a lower connection ring 407. A spring 408 is installed between the upper connection ring 405 and the lower connection ring 407. A medical dressing 409 is installed at the bottom of the lower connection ring 407. A sponge sheet 410 is fixedly connected to the center of the bottom of the medical dressing 409. A gauze sheet 411 is fixedly connected to the bottom of the sponge sheet 410.

[0033] It should be noted that during use, first, the sponge sheet 410 and the gauze sheet 411 are closely attached to the wound surface through the medical dressing 409. Then, one end of the second connection hose 3 and the other end of the connection valve 402 are connected to the intake pipe 107 of the drainage mechanism 1. At the same time, the negative pressure aspirator 201 is started to perform negative pressure drainage on the air inside the wound dressing mechanism 4 through the drainage mechanism 1, the negative pressure mechanism 2, the second connection hose 3, and the suction hood 401. During this process, under the action of pressure, the upper connection ring 405, the telescopic tube 406, and the lower connection ring 407 are closely attached to the wound surface under the action of the spring 408 to form a sealed space. When it is necessary to adjust the pressure and inject liquid medicine, manually remove the rubber plug 404, and release the pressure and perform operations through the liquid injection tube 403. The connection ring and the telescopic tube 406 and other components provided in the wound dressing mechanism 4 cooperate with each other to adapt to wound surfaces of different shapes, ensuring the stability of the negative pressure and improving work efficiency.
