Description

Technical Field

[0001] This utility model relates to the field of vacuum negative pressure machine technology, specifically an integrated vacuum negative pressure machine. Background Technology

[0002] An integrated vacuum negative pressure machine is a device that integrates vacuum generation, negative pressure control, and related functions into one unit. It is commonly used in the medical field. During surgical procedures, a large amount of blood, exudate, and tissue debris are generated. The integrated vacuum negative pressure machine can remove these substances in a timely manner, maintain a clear surgical field, facilitate doctors to perform precise operations, and improve the accuracy and safety of the surgery. At the same time, the integrated vacuum negative pressure machine creates a negative pressure environment on the wound surface, promoting the drainage of exudate from the wound, increasing local blood perfusion, stimulating granulation tissue growth, and accelerating wound healing.

[0003] Existing integrated vacuum negative pressure machines are usually equipped with collection containers to collect aspirates. However, during surgery or wound drainage, blood mixed with tissue fragments and wound exudate mixed with necrotic tissue, these solid-liquid mixtures are simultaneously drawn into the collection container, increasing the difficulty of subsequent processing and easily causing secondary pollution.

[0004] Therefore, those skilled in the art have provided an integrated vacuum negative pressure machine to solve the problems mentioned in the background art. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Reference Figure 1 - Figure 5This embodiment provides an integrated vacuum negative pressure machine, including a vacuum tank 1. A separation component 2 is disposed on the top of the vacuum tank 1. The separation component 2 includes a support column 201, which is fixedly connected to a negative pressure collection box 202. A connecting pipe 203 is fixedly connected to the top of the vacuum tank 1, and the connecting pipe 203 is fixedly connected to one side of the negative pressure collection box 202. A bonding plate 204 is movably connected inside the negative pressure collection box 202. A solid separation screen 205 is fixedly connected to one side of the bonding plate 204, and a liquid collection screen is fixedly connected to one side of the bonding plate 204. The collection frame 206 and the negative pressure collection box 202 have a connecting groove 207 on the other side. A return spring 208 is fixedly connected to the top of the inner wall of the connecting groove 207, and a fixing plate 209 is fixedly connected to the bottom of the return spring 208. A limit rod 210 is fixedly connected to the bottom of the fixing plate 209. An adhesive block 211 is movably connected inside the connecting groove 207. The adhesive block 211 is fixedly connected to the adhesive plate 204. A limit hole 212 is opened inside the adhesive block 211. The suction material enters the negative pressure collection box 202 through the suction tube 3. After the pressure collection box 202 is pressed, the liquid rushes towards the solid separation screen 205 under negative pressure. The solid matter in the suction is intercepted by the solid separation screen 205, while the liquid flows through the solid separation screen 205 into the liquid collection frame 206 below, achieving solid-liquid separation. After completion, the medical staff pulls the fixing plate 209 upward, causing the limiting rod 210 to rise. The return spring 208 is compressed, causing the limiting rod 210 to rise. When the limiting rod 210 is completely pulled out of the limiting hole 212, the restriction on the bonding block 211 is released. At this time, in the connecting groove 20 Guided by 7, medical staff can easily remove the bonding plate 204 from the negative pressure collection box 202. Subsequently, the solid matter intercepted on the solid separation screen 205 and the liquid in the liquid collection box 206 can be professionally treated as medical waste. After treatment, the bonding plate 204 is reinstalled back into the negative pressure collection box 202. Under the elastic action of the return spring 208, the fixing plate 209 drives the limiting rod 210 to descend and pass through the limiting hole 212 again to complete the fixing of the bonding plate 204. The equipment can then continue to be used.

[0026] Example 2

[0027] Reference Figure 1 - Figure 5This embodiment is based on the previous embodiment, but differs in that a suction tube 3 is fixedly connected to the top of the negative pressure collection box 202, a handheld block 4 is fixedly connected to the side surface of the suction tube 3, a fixing ring 5 is fixedly fitted to the side surface of the vacuum tank 1, a box body 6 is fixedly connected to one side of the fixing ring 5, a vacuum pump 7 is connected inside the box body 6, an air extraction pipe 8 is fixedly connected to the other side of the vacuum pump 7, and the other side of the air extraction pipe 8 is fixedly connected to the vacuum tank 1. An exhaust port 9 is opened on one side of the inner wall of the box body 6, a filter screen 10 is fixedly connected inside the exhaust port 9, a base plate 11 is fixedly connected to the bottom of the box body 6, a caster wheel 12 is fixedly connected to the bottom of the base plate 11, a control panel 13 is fixedly connected to one side of the box body 6, a rubber sealing gasket is provided on the contact surface between the bonding plate 204 and the negative pressure collection box 202, the bonding block 211 and the connecting groove 207 are symmetrically distributed, the limiting rod 210 is adapted to the limiting hole 212, and the suction tube 3... Made of flexible material, the handheld block 4 has anti-slip textures on its surface. The housing 6 is made of corrosion-resistant material. There are four casters 12 arranged in a rectangular array. The base plate 11 is made of high-strength aluminum alloy. The wheels of the casters 12 are made of high-elasticity polyurethane material. In use, medical staff move the device to the location where it is needed using the casters 12. The medical staff turns on the power switch on the control panel 13, and the vacuum pump 7 starts to work. The vacuum pump 7 draws air from the vacuum tank 1 through the suction pipe 8, creating a negative pressure environment inside the vacuum tank 1. Since the vacuum tank 1 and the negative pressure collection box 202 are fixedly connected through the connecting pipe 203, a negative pressure is also created inside the negative pressure collection box 202. Then, the medical staff holds the handheld block 4 and uses the suction tube 3 to perform medical suction. The vacuum pump 7 continues to work, drawing out the gas from the vacuum tank 1 and the negative pressure collection box 202 and discharging it through the exhaust port 9 until the suction operation is completed.
