Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically, it is a vacuum pump negative pressure scar treatment device. Background Art

[0002] Scars are common complications after skin injury repair. When the skin is damaged by external forces, such as cuts, burns, abrasions, surgical traumas, etc., the normal structure of the skin will be destroyed. In order to repair these injuries, the body will produce collagen to fill the wound. However, during this repair process, if the synthesis and arrangement of collagen are abnormal, scars will be formed.

[0003] Vacuum pump negative pressure scar treatment is an innovative scar repair method. Its treatment principle is to generate negative pressure through a vacuum pump and place the scar tissue in a specific negative pressure environment. This negative pressure environment can stimulate the cell activities inside the scar tissue, promote cell proliferation and differentiation, and accelerate the scar repair process. At the same time, the negative pressure can also improve the blood circulation of the scar tissue, increase the supply of nutrients, and contribute to the recovery and remodeling of the scar tissue.

[0004] For example, a portable vacuum pump negative pressure scar treatment device disclosed in a Chinese patent (authorization announcement number CN114533977A). When this device is in use, after the drainage bottle is filled with liquid, the second bottle is removed from the first bottle, and then an empty second bottle is installed on the first bottle. Thus, it is not necessary to clamp the drainage tube and stop the main unit to replace the drainage bottle, so that the main unit of the present invention still generates negative pressure when replacing the second bottle, so that the negative pressure at the patient's wound will not be interrupted, and the treatment at the patient's wound will not be interrupted, ensuring the treatment effect of the wound and reducing the formation of scars after wound healing.

[0005] However, when this device is in use, it cannot timely remind medical staff or patients when the drainage is full, and it is necessary for patients or medical staff to always pay attention to the drainage bottle, increasing the labor intensity of medical staff. At the same time, when replacing the drainage bottle, after the first bottle and the second bottle are separated, the first bottle can be sealed. During the separation process, the drainage fluid is likely to spill, and medical staff need to be very careful when replacing it. If the drainage fluid falls on the hands of medical staff or on the ground, it will cause environmental pollution and the problem of pathological pollution.

[0006] Therefore, technical personnel in this field have provided a vacuum pump negative pressure scar treatment device to solve the problems raised in the above background art. Summary of the Invention

[0007] To solve the disadvantages in the prior art that there is no timely reminder when the drainage bottle is full and it is easy to spill during replacement, we propose a vacuum pump negative pressure scar treatment device.

A synchronous rod is fixedly connected to the side of the synchronous gear away from the placement plate. An extrusion rod is fixedly connected to the synchronous rod, and the extrusion rod is slidably connected in the fullness reminder assembly.

[0014] Further: The fullness reminder assembly includes an adjustment disk. The adjustment disk is fixedly connected to the placement frame. An adjustment groove is opened on the side of the adjustment disk away from the synchronous gear. The extrusion rod is slidably connected in the adjustment groove, and a plurality of induction blocks are also arranged on the inner wall of the adjustment groove;

[0015] An alarm is also installed on the outer wall of the placement frame. The alarm is connected to a plurality of induction blocks through a connecting wire.

[0016] Further: A communicating pipe is arranged at the bottom of the first drainage bottle. A first thread groove is opened on the outer wall of the communicating pipe, and the first thread groove is arranged at one end of the communicating pipe close to the first drainage bottle.

[0017] Further: The sealing assembly includes a rotating disk, which is rotatably connected to the first drainage bottle. Two communication holes and two second moving grooves are symmetrically arranged at the center of the rotating disk. On each of the two second moving grooves, a sealing plate for closing the first drainage bottle is slidably connected through a connecting shaft. A sealing gasket is fixedly connected to one side of each of the two sealing plates close to each other.

[0018] Two displacement grooves are further provided at the bottom of the first drainage bottle. The second drainage bottle is connected to the sealing assembly through the two displacement grooves.

[0019] Further: A limiting gear is also rotatably connected in the first drainage bottle, and the limiting gear meshes with the rotating disk. A limiting disk is rotatably connected to the bottom of the limiting gear. The limiting disk is fixedly connected to the inner wall of the first drainage bottle, and a torsion spring is arranged in the limiting disk. One side of the limiting gear close to the limiting disk is connected to the torsion spring in the limiting disk through a connecting shaft. A blocking tooth block is clamped on the side of the limiting gear away from the rotating disk. One end of the blocking tooth block away from the limiting gear penetrates through the side wall of the first drainage bottle and extends to the outside of the first drainage bottle.

[0020] A first moving groove for the blocking tooth block to slide is provided on the side wall of the first drainage bottle.

The two driving rods respectively penetrate through the adjacent displacement grooves and are inserted into the communication holes.

[0022] A one-way valve is hinged to the bottom of the drainage port.

[0023] The effects of the above solution are as follows:

[0024] 1. Through the built-in intelligent monitoring structure, the present invention can monitor the amount of drainage fluid in the second drainage bottle in real time. As the drainage fluid increases, the weight of the second drainage bottle gradually increases, triggering the linkage mechanism of the synchronous rack and the synchronous gear, and then driving the extrusion rod to slide in the adjustment groove and contact the induction block. Once the induction block is triggered, the alarm immediately sounds, reminding the medical staff to replace the drainage bottle in time. This intelligent design not only improves the safety of the treatment process but also effectively avoids the interruption of the treatment caused by the overfilled drainage bottle. At the same time, when the drainage fluid in the second drainage bottle gradually increases, the greater the downward movement amplitude of the placement plate, the louder the warning volume. By continuously increasing the warning volume, the warning effect is improved.

[0025] 2. When the present invention is in use, when the drainage volume in the second drainage bottle reaches a certain level, the device can automatically close the channel. The ingenious cooperation of the limiting gear and the torsion spring enables the limiting gear to rotate reversely under the action of the torsion spring during the continuous downward movement of the first drainage bottle, driving the sealing plates to approach each other and close the channel. This design ensures that the drainage fluid will not spill during the replacement of the drainage bottle, effectively avoiding the risks of contamination and cross-infection. At the same time, the replacement process of the drainage bottle is extremely convenient. After the sealing plates close the first drainage bottle, medical staff only need to pull out the second drainage bottle from the bottom of the first drainage bottle, greatly saving the operation time.

[0026] 3. Through the ingenious combination of the first drainage bottle and the second drainage bottle, the present invention not only ensures the smooth flow of the drainage fluid, but also effectively prevents the backflow and leakage of the drainage fluid through the setting of the one-way valve and the sealing assembly. During the negative pressure treatment process, the start of the vacuum pump can quickly form a negative pressure environment, promoting the blood circulation and lymphatic return of the scar tissue, accelerating the softening and regression of the scar, and thus significantly improving the treatment effect.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely introduced in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] Example 1, please refer to Figures 1-10 , a vacuum pump negative pressure scar treatment device, including a chassis 1, a vacuum pump is installed in the chassis 1, a fixing ring 13 is slidably connected to one side of the chassis 1, a return spring is fixedly connected to the bottom of the fixing ring 13, and the other end of the return spring is fixed to the chassis 1. A first drainage bottle 3 is fixedly connected to the fixing ring 13. The output end of the first drainage bottle 3 is communicated with a suction component. The output end of the vacuum pump is communicated with a vent pipe 11. The other end of the vent pipe 11 is communicated with the suction component through the first drainage bottle 3. A placing component 2 is fixedly connected to one side of the chassis 1 close to the first drainage bottle 3. The lower part of the first drainage bottle 3 is communicated with a second drainage bottle 5, and the second drainage bottle 5 is placed in the placing component 2. A sealing component 6 for sealing the first drainage bottle 3 to prevent leakage is arranged in the inner wall of the bottom of the first drainage bottle 3. A full overflow reminder component 4 for reminding the drainage volume in the second drainage bottle 5 is also arranged in the placing component 2. The suction component includes a drainage pipe 31. One end of the drainage pipe 31 is communicated with the first drainage bottle 3, and the other end is fixedly connected with a suction cup 32. A fixing patch 33 is fixedly connected to the suction cup 32;

[0041] When using this device, first place the second drainage bottle 5 on the placement assembly 2 to connect the first drainage bottle 3 with the second drainage bottle 5. After connection, place a sterile sponge at the patient's wound, place the suction cup 32 on the sterile sponge, and use the fixing patch 33 to fix the suction cup 32 to the patient's skin to fix the suction cup 32. After fixing, start the vacuum pump in the chassis 1 to make the vacuum pump generate negative pressure, stimulate the cell activities inside the scar tissue through negative pressure suction, and aspirate the exudate generated at the wound, etc., to keep the wound clean and dry;

[0042] When aspirating the waste liquid generated at the wound, the waste liquid first enters the drainage tube 31 through the suction cup 32 and falls into the first drainage bottle 3 through the drainage tube 31. Since the first drainage bottle 3 is connected to the second drainage bottle 5, the waste liquid can enter the second drainage bottle 5 through the first drainage bottle 3 for collection. When the waste liquid in the second drainage bottle 5 gradually increases, the weight of the second drainage bottle 5 continuously increases, and the overflow reminder component 4 in the placement assembly 2 is activated, and the medical staff or the patient is reminded in time through the overflow reminder component 4 to replace the new drainage bottle in time.

[0043] Example 2, please refer to Figures 1-10, the placement component 2 includes a placement frame 21. Sliding grooves 22 are formed on the inner walls on both sides of the placement frame 21. A placement plate 23 is slidably arranged in the placement frame 21, and both sides of the placement plate 23 are respectively slidably connected to the two sliding grooves 22. A pressure spring 24 is fixedly connected to the bottom of the placement plate 23, and the other end of the pressure spring 24 is fixedly connected to the inner wall of the bottom of the placement frame 21. A synchronous rack 25 is fixedly connected to one side of the placement plate 23. A synchronous gear 26 is arranged on one side of the synchronous rack 25, and the synchronous gear 26 is rotatably connected to the inner wall of the placement frame 21. A synchronous rod 27 is fixedly connected to the side of the synchronous gear 26 away from the placement plate 23. An extrusion rod 28 is fixedly connected to the synchronous rod 27. The extrusion rod 28 is slidably connected to the overflow reminder component 4. The overflow reminder component 4 includes an adjustment disk 41. The adjustment disk 41 is fixedly connected to the placement frame 21. An adjustment groove 42 is formed on the side of the adjustment disk 41 away from the synchronous gear 26. The extrusion rod 28 is slidably connected to the adjustment groove 42. A plurality of induction blocks 43 are further arranged on the inner wall of the adjustment groove 42. An alarm 44 is further installed on the outer wall of the placement frame 21. The alarm 44 is connected to the plurality of induction blocks 43 through a connecting wire. A communication pipe 34 is arranged at the bottom of the first drainage bottle 3. A first thread groove 35 is formed on the outer wall of the communication pipe 34, and the first thread groove 35 is arranged at one end of the communication pipe 34 close to the first drainage bottle 3. A drainage port 51 adapted to the communication pipe 34 is formed at the top of the second drainage bottle 5. A second thread groove 52 adapted to the first thread groove 35 is formed on the inner wall of the drainage port 51. Two driving rods 54 are fixedly connected to the top of the drainage port 51. The two driving rods 54 respectively penetrate through the adjacent displacement grooves 36 and are inserted into the communication holes 62. A one-way valve 53 is further hinged to the bottom of the drainage port 51;

[0044] During use, first place the second drainage bottle 5 on the placement plate 23, insert the communication pipe 34 at the bottom of the first drainage bottle 3 into the drainage port 51 at the top of the second drainage bottle 5 and push open the one-way valve 53. At the same time, insert the two driving rods 54 at the top of the second drainage bottle 5 into the sealing component 6 respectively through the two displacement grooves 36. After being inserted properly, slightly rotate the second drainage bottle 5 to engage the second thread groove 52 on the second drainage bottle 5 with the first thread groove 35 on the communication pipe 34, so as to further fix the first drainage bottle 3 and the second drainage bottle 5. When the second drainage bottle 5 rotates, it simultaneously drives the sealing component 6 to rotate, so as to open the sealing component 6 and connect the first drainage bottle 3 and the second drainage bottle 5. After being connected, start the vacuum pump for negative pressure treatment;

[0045] During negative pressure treatment, as the drainage fluid in the second drainage bottle 5 continuously increases, the weight of the second drainage bottle 5 gradually increases, causing the second drainage bottle 5 to continuously press down the placement plate 23. When the placement plate 23 moves downward, it simultaneously drives the synchronous rack 25 to move downward within the placement frame 21. The synchronous rack 25 simultaneously meshes with the synchronous gear 26, causing the synchronous gear 26 to rotate. When the synchronous gear 26 rotates, it simultaneously drives the extrusion rod 28 to slide within the adjustment slot 42 through the synchronous rod 27. The extrusion rod 28 gradually contacts the induction block 43 within the adjustment slot 42 during the continuous rotation of the synchronous rod 27. After contacting the induction block 43, it triggers the induction block 43 to emit an alarm through the alarm 44, prompting medical staff to replace the drainage bottle;

[0046] By setting multiple induction blocks 43, during use, when medical staff do not replace the drainage bottle after one reminder, the placement plate 23 will continue to move downward, driving the synchronous gear 26 to continue rotating, causing the extrusion rod 28 to contact the next induction block 43 and increasing the volume to issue a reminder again. By continuously increasing the warning volume, the warning effect is improved. Therefore, when the drainage fluid in the second drainage bottle 5 gradually increases, the greater the downward movement amplitude of the placement plate 23, the greater the warning volume;

[0047] When the liquid volume in the second drainage bottle 5 continues to increase, the sealing component 6 in the first drainage bottle 3 is triggered, closing the communication port between the first drainage bottle 3 and the second drainage bottle 5. At this time, the drainage fluid will be collected in the first drainage bottle 3 to prevent spillage of the excessive drainage fluid in the second drainage bottle 5 during replacement.

[0048] Example three, please refer to Figure 1 、 Figure 5 、 Figure 6 and Figure 7, the sealing assembly 6 includes a rotating disk 61 which is rotatably connected to the first drainage bottle 3. Two communication holes 62 and two second moving grooves 63 are symmetrically arranged at the center of the rotating disk 61. A sealing plate 64 for closing the first drainage bottle 3 is slidably connected to each of the two second moving grooves 63 through a connecting shaft. Sealing gaskets are fixedly connected to one side of the two sealing plates 64 close to each other. Two displacement grooves 36 are further formed at the bottom of the first drainage bottle 3. The second drainage bottle 5 is connected to the sealing assembly 6 through the two displacement grooves 36. A limiting gear 65 is also rotatably connected in the first drainage bottle 3, and the limiting gear 65 meshes with the rotating disk 61. A limiting disk 66 is rotatably connected to the bottom of the limiting gear 65. The limiting disk 66 is fixedly connected to the inner wall of the first drainage bottle 3, and a torsion spring is arranged in the limiting disk 66. One side of the limiting gear 65 close to the limiting disk 66 is connected to the torsion spring in the limiting disk 66 through a connecting shaft. A stop tooth block 67 is clamped on the side of the limiting gear 65 far from the rotating disk 61. One end of the stop tooth block 67 far from the limiting gear 65 penetrates through the side wall of the first drainage bottle 3 and extends to the outside of the first drainage bottle 3. A first moving groove 37 for the stop tooth block 67 to slide is formed on the side wall of the first drainage bottle 3. A limiting groove 12 with the same position as the first moving groove 37 is formed on one side of the chassis 1 close to the first drainage bottle 3. A sliding shaft is hinged to the bottom of the stop tooth block 67, and the sliding shaft is slidably connected in the limiting groove 12;

[0049] In the initial state, the two sealing plates 64 are attached to each other, and the bottom of the first drainage bottle 3 is in a closed state. When the second drainage bottle 5 is connected to the first drainage bottle 3, the two driving rods 54 are simultaneously inserted into the two communication holes 62. When the second drainage bottle 5 is rotated to further fix the second drainage bottle 5 to the first drainage bottle 3, the driving rods 54 simultaneously drive the rotating disk 61 to rotate. By rotating the rotating disk 61, the connecting shaft in the second moving groove 63 is pushed to drive the sealing plate 64 to move, so that the two sealing plates 64 move away from each other, and the first drainage bottle 3 is communicated with the second drainage bottle 5;

[0050] At the same time, when the rotating disk 61 rotates, the rotating disk 61 simultaneously drives the limiting gear 65 to rotate, so that the limiting gear 65 drives the torsion spring in the limiting disk 66 to contract and store energy;

[0051] When the first drainage bottle 3 and the second drainage bottle 5 are fixed, the limiting gear 65 is fixed under the limitation of the stop tooth block 67, so that the torsion spring always remains in a state of storing energy;

[0052] When the drainage volume in the second drainage bottle 5 continuously increases and causes the second drainage bottle 5 to drive the first drainage bottle 3 to gradually move downward, the blocking tooth block 67 simultaneously moves downward along the limiting groove 12 following the first drainage bottle 3. When the blocking tooth block 67 moves downward to abut against the bottom of the limiting groove 12, the second drainage bottle 5 continues to move downward. The blocking tooth block 67 cannot continue to move downward under the limitation of the limiting groove 12. At this time, the first drainage bottle 3 still follows the second drainage bottle 5 to move downward. Under the relative action of the first drainage bottle 3, the blocking tooth block 67 gradually disengages from the limiting gear 65. The limiting gear 65 is no longer limited by the blocking tooth block 67, and the torsion spring in the limiting disk 66 rebounds and resets, simultaneously driving the limiting gear 65 to rotate. The limiting gear 65 drives the rotating disk 61 to rotate in the reverse direction, causing the two sealing plates 64 to move towards each other, so that the two sealing plates 64 close the channel between the first drainage bottle 3 and the second drainage bottle 5;

[0053] When the rotating disk 61 rotates in the reverse direction, it simultaneously pushes the second drainage bottle 5 to rotate through the driving rod 54, causing the second thread groove 52 to disengage from the first thread groove 35. When medical staff replace the drainage bottle, they only need to pull out the second drainage bottle 5 from the bottom of the first drainage bottle 3, which is convenient for replacement. At the same time, since the connecting pipe 34 is still inserted into the drainage port 51 at this time, even if the second thread groove 52 is separated from the first thread groove 35, the drainage fluid will not leak out;

[0054] After replacement, the fixing ring 13 resets and drives the first drainage bottle 3 to move upward, so that the blocking tooth block 67 can be engaged with the limiting gear 65 again, and the above work is repeated again.

[0055] The working principle of the present invention is:

[0056] When using this device, first place the second drainage bottle 5 on the placing plate 23, and insert the connecting pipe 34 at the bottom of the first drainage bottle 3 into the drainage port 51 at the top of the second drainage bottle 5 to push open the one-way valve 53. At the same time, insert the two driving rods 54 at the top of the second drainage bottle 5 into the sealing assembly 6 through the two displacement grooves 36 respectively. After being plugged in, slightly rotate the second drainage bottle 5 to engage the second thread groove 52 on the second drainage bottle 5 with the first thread groove 35 on the connecting pipe 34, so as to further fix the first drainage bottle 3 and the second drainage bottle 5. When the second drainage bottle 5 rotates, it simultaneously drives the sealing assembly 6 to rotate, so that the sealing assembly 6 is opened, and the first drainage bottle 3 and the second drainage bottle 5 are connected. After connection, start the vacuum pump for negative pressure treatment;

[0057] During the negative pressure treatment, as the drainage fluid in the second drainage bottle 5 continuously increases, the weight of the second drainage bottle 5 gradually increases, causing the second drainage bottle 5 to continuously press down the placement plate 23. When the placement plate 23 moves downward, it simultaneously drives the synchronous rack 25 to move downward within the placement frame 21. The synchronous rack 25 simultaneously meshes with the synchronous gear 26, causing the synchronous gear 26 to rotate. When the synchronous gear 26 rotates, it simultaneously drives the extrusion rod 28 to slide within the adjustment groove 42 through the synchronous rod 27. The extrusion rod 28 gradually contacts the induction block 43 within the adjustment groove 42 during the continuous rotation of the synchronous rod 27. After contacting the induction block 43, it triggers the induction block 43 to emit an alarm through the alarm 44, prompting the medical staff to replace the drainage bottle;

[0058] When the drainage volume in the second drainage bottle 5 continuously increases and causes the second drainage bottle 5 to drive the first drainage bottle 3 to gradually move downward, the blocking tooth block 67 simultaneously follows the first drainage bottle 3 and moves downward along the limiting groove 12. When the blocking tooth block 67 moves downward to abut against the bottom of the limiting groove 12, the second drainage bottle 5 continues to move downward. The blocking tooth block 67 cannot continue to move downward under the limitation of the limiting groove 12. At this time, the first drainage bottle 3 still follows the second drainage bottle 5 and moves downward. Under the relative action of the first drainage bottle 3, the blocking tooth block 67 gradually disengages from the limiting gear 65. The limiting gear 65 is no longer limited by the blocking tooth block 67, and the torsion spring within the limiting disk 66 rebounds and resets, simultaneously driving the limiting gear 65 to rotate. The limiting gear 65 drives the rotating disk 61 to rotate in the reverse direction, causing the two sealing plates 64 to move towards each other, closing the channel between the first drainage bottle 3 and the second drainage bottle 5. At this time, the drainage fluid will be collected in the first drainage bottle 3, preventing the drainage fluid in the second drainage bottle 5 from spilling during replacement. When replacing the drainage bottle, the medical staff only needs to pull out the second drainage bottle 5 from the bottom of the first drainage bottle 3, which is convenient for replacement. At the same time, since the connecting pipe 34 is still inserted into the drainage port 51 at this time, even if the second thread groove 52 is separated from the first thread groove 35, the drainage fluid will not leak. After the second drainage bottle 5 is separated from the first drainage bottle 3, the one-way valve 53 is no longer pushed by the connecting pipe 34, gradually resets and closes the drainage port 51, preventing the drainage fluid in the second drainage bottle 5 from spilling and causing pollution during replacement.

[0059] It should be noted that the devices in this application are all common devices in the market and can be selected according to requirements during specific use. Moreover, the circuit connection relationships of the devices all belong to simple series and parallel connection circuits, and there are no innovation points in the circuit connection part. Those skilled in the art can easily implement them, which belong to the prior art and will not be elaborated further.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
