Description

Technical Field

[0001] The present invention relates to the technical field of drainage bag hanging, and specifically, to an adsorption type drainage bag hanging device. Background Art

[0002] In the medical field, a drainage bag is a commonly used medical instrument, which is mainly used to collect various liquids generated by the human body during surgery, trauma or illness, including pus, exudate, etc. Currently, the drainage bag is usually hooked on the edge of the hospital bed, and the purpose of drainage is achieved by means of the height difference.

[0003] For ordinary liquids, such as urine and exudate, their components are relatively simple. Due to the simplicity of their components, these liquids have good fluidity. During the drainage process, they are not easy to adhere to and accumulate on the inner wall of the drainage tube, so it is more convenient to perform the drainage operation. When draining such liquids, usually the key point is to pay attention to the hanging stability.

[0004] However, when it comes to draining liquids with high viscosity, such as pus, due to the presence of a large amount of cell debris, bacteria, proteins, necrotic tissues and other substances in it, the viscosity of the pus increases significantly and the fluidity decreases. Especially during the process from the drainage tube into the drainage bag, the pressure and flow rate will change. This change is likely to cause the solid components in the pus to precipitate and accumulate. At the connection part of the conventional drainage tube and the drainage bag, the inner diameter size of the drainage bag is larger than that of the drainage tube. This change in the pipe diameter size results in a greater fluid flow resistance at this place than other parts of the drainage tube or the drainage bag (according to the principle of fluid mechanics, the fluid flow resistance in a pipe is related to the diameter of the pipe. At the place where the diameter changes, such as the connection part of the drainage tube and the drainage bag, due to the change in the cross-sectional area, the flow resistance will increase). When the drained substance is thick pus, due to its viscous nature, it is more likely to experience poor flow and stagnation at the interface with a large flow resistance. Once the pus stagnates at this critical position, it is easy to cause blockage, which will not only affect the drainage effect, but also may cause doctors to be unable to accurately judge the progress of the disease and the treatment effect, delaying the treatment opportunity. At this time, not only the hanging stability of the drainage bag needs to be concerned, but also the problem of blockage at the interface between the drainage bag and the drainage tube needs to be particularly noted.

[0005] In view of this, we propose an adsorption type drainage bag hanging device. Summary of the Invention

[0006] The purpose of the present invention is to provide an adsorption type drainage bag hanging device to solve the problems raised in the above background art.

One side of the four support rods extending out of the surface of the vertical bonding plate is movably connected to an external attachment plate. After the drainage bag body is hung, the external attachment plate covers the outside of the drainage bag body.

[0013] As a further improvement of the technical solution, the driving group includes a middle cavity opened inside the vertical fitting plate.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment, please refer to Figure 1 、 Figure 2 and Figure 6As shown in the figure, the purpose of this embodiment is to provide an adsorption type drainage bag hanging device, which includes a hanging mechanism 1. The hanging mechanism 1 is installed on the surface of the bed edge rod 10. A drainage member 101 is hung on the surface of the hanging mechanism 1. The drainage member 101 includes a drainage bag body 104. A connecting pipe fitting 103 is connected to the top opening of the drainage bag body 104. A drainage pipe 102 is inserted and installed inside the connecting pipe fitting 103 to connect the inside of the drainage bag body 104 with the drainage pipe 102. A hanging ring is fixedly connected to the top of the drainage bag body 104;

[0037] The hanging mechanism 1 includes an adsorption component group 11 and a hanging rod body 113. The adsorption component group 11 is used for adsorbing and fixing on the surface of the bed edge rod 10. The hanging rod body 113 is installed on the side wall of the adsorption component group 11. The hanging rod body 113 is used for assisting in hanging the drainage bag body 104. An external attachment mechanism 2 is movably connected to the outer wall of the adsorption component group 11;

[0038] When the drainage bag body 104 is hung on the side wall of the bed edge rod 10, the external attachment mechanism 2 is used for physically blocking the connecting pipe fitting 103. The external attachment mechanism 2 includes a driving group 22 and a dredging group 23;

[0039] When draining a liquid with high fluidity, the dredging group 23 can assist in limiting the connecting pipe fitting 103. When draining a liquid with low fluidity, the driving group 22 can drive the dredging group 23 to continuously move slightly left and right, and during the movement, it is used for squeezing and dredging the connecting pipe fitting 103.

[0040] The drainage bag body 104 usually needs to be hung on the hanging rod body 113 on the side wall of the bed edge rod 10 of the hospital bed, and the purpose of drainage is achieved by means of the height difference. And the hanging rod body 113 is adsorbed on the side wall of the bed edge rod 10 by means of the adsorption component group 11. Therefore, combined with Figure 7 First, the specific structure of the adsorption component group 11 is disclosed. The adsorption component group 11 further includes a horizontal fitting plate 111 and a vertical fitting plate 112. The horizontal fitting plate 111 and the vertical fitting plate 112 are fixedly connected. The included angle after the connection of the horizontal fitting plate 111 and the vertical fitting plate 112 is ninety degrees. The hanging rod body 113 is located on the surface of the vertical fitting plate 112. A placement groove 13 is opened on the surface of the vertical fitting plate 112 away from the hanging rod body 113. A first adsorption component 12 is arranged inside the placement groove 13. One end of the horizontal fitting plate 111 close to the vertical fitting plate 112 is fixedly connected with a second adsorption component 14.

[0041] The horizontal fitting plate 111 and the vertical fitting plate 112 are fixedly connected. A second adsorbent 14 is fixedly connected to the surface of the horizontal fitting plate 111, and a first adsorbent 12 is arranged on the surface of the vertical fitting plate 112. In this way, the horizontal fitting plate 111 and the vertical fitting plate 112 can be adsorbed on the surface of the bed edge rod 10 by means of the first adsorbent 12 and the second adsorbent 14.

[0042] Considering that the hospital bed and the bed edge rod 10 of the hospital bed are usually made of metal (such as iron), and there are few scratches on the top of the bed edge rod 10 due to less contact, the second adsorbent 14 equipped on the horizontal fitting plate 111 attached to the top of the bed edge rod 10 adopts a magnetic adsorption structure, which can drive the horizontal fitting plate 111 to be efficiently adsorbed on the top of the bed edge rod 10;

[0043] Since the side wall of the hospital bed is easily touched when people move around, it is easy to produce scratches or be contaminated with other impurities. Therefore, the vertical fitting plate 112 attached to the side wall of the bed edge rod 10 can be made of micro-nano silica gel surface with relatively soft material and self-adhesive force. On the one hand, this micro-nano silica gel surface can closely fit on the side wall of the bed edge rod 10 to provide a reliable adsorption force for the vertical fitting plate 112; on the other hand, its soft material can adapt to the uneven surface of the side wall of the bed edge rod 10 caused by scratches, etc., effectively reducing the occurrence of accidental detachment caused by insecure adsorption, and providing a solid guarantee for the stable hanging of the drainage bag body 104.

[0044] After the drainage bag body 104 is hooked on the hanging rod body 113, the whole drainage part 101 is in an unobstructed state. Therefore, after the hanging connection is completed, covering the outer attachment mechanism 2 on the surface of the drainage bag body 104 can further improve the hanging stability of the drainage bag body 104. The outer attachment mechanism 2 includes four support rods 24 inserted into the vertical fitting plate 112, and one side of the four support rods 24 extending out of the surface of the vertical fitting plate 112 is movably connected to the outer attachment plate 21.

[0045] Refer to Figure 2 And in combination with Figure 3As shown, the four support rods 24 are all inserted into the inside of the vertical fitting plate 112, and one end of the four support rods 24 close to the hanging rod body 113 is inserted and connected to the outer attachment plate 21. After the drainage bag body 104 is hung up, the outer attachment plate 21 can effectively externally shield the drainage bag body 104, which can greatly improve the hanging stability of the drainage bag body 104. Even when there is a certain degree of vibration or slight external force interference in the surrounding environment, the drainage bag body 104 can be firmly hung on the hanging rod body 113 and will not easily shake or fall off. At the same time, through the shielding of the outer attachment plate 21, the entry of dust and impurities into the connecting pipe fitting 103 can be significantly reduced, keeping the connecting pipe fitting 103 clean and reducing the risk of infection or blockage caused by the entry of dust and impurities, providing a more reliable guarantee for the normal use of the drainage bag body 104 and the treatment of patients.

[0046] Among them, a plug-in high-magnetic adsorption connection structure (not shown in the figure) is adopted between the four support rods 24 and the outer attachment plate 21. One end of the support rod 24 is designed with a specific plug-in structure that can match the corresponding jacks on the outer attachment plate 21 to achieve plug-in connection. At the same time, near the plug-in part, high-magnetic materials are used for adsorption and reinforcement. This connection method enables the outer attachment plate 21 and the support rod 24 to not only achieve preliminary positioning and connection stability through plug-in connection, but also further enhance the firmness of the connection by means of high-magnetic adsorption force. While ensuring that the outer attachment plate 21 will not easily fall off the support rod 24 during use, it makes the connection and disassembly between the support rod 24 and the outer attachment plate 21 more convenient, providing a reliable structural support for the stable shielding and hanging of the drainage bag body 104.

[0047] Considering that in the self-structure of the drainage bag body 104, the hook rings of some models are not aligned with the drainage bag body 104. In view of this situation, in order to enable the outer attachment plate 21 to better adapt to different drainage bag bodies 104, the end of the support rod 24 connected to the outer attachment plate 21 is connected to the drive group 22. The drive group 22 includes a middle cavity 221 opened inside the vertical fitting plate 112. Two fixing plates 222 are fixedly connected to the middle of the middle cavity 221. A drive chamber 223 is formed between the two fixing plates 222. Two micro lead screws 224 are rotatably arranged inside the middle cavity 221. The two micro lead screws 224 are respectively fixedly connected to the two output shafts of the micro double-shaft drive motor, and the micro double-shaft drive motor is fixedly installed inside the drive chamber 223. A connecting rod 225 is fixedly connected between two adjacent support rods 24. The two connecting rods 225 respectively slide on the surfaces of the two micro lead screws 224.

[0048] Eight wide holes 4 are opened on the inner wall of the middle cavity 221. The four support rods 24 are respectively inserted and slide inside the eight wide holes 4. The four wide holes 4 far from the outer attachment plate 21 are communicated with the placement groove 13. One side of the four support rods 24 far from the outer attachment plate 21 is connected to the first adsorbent 12.

[0049] Combined Figure 6 As shown, the positions of two adjacent struts 24 inside the middle cavity 221 are connected by a connecting rod 225. The two connecting rods 225 are respectively connected to the surfaces of two micro lead screws 224. Start the micro biaxial motor (wireless structure, using remote control technology), which drives the two micro lead screws 224 fixedly connected to its two output shafts to rotate inside the middle cavity 221. Thus, the four struts 24 can achieve synchronous and co-directional displacement. Among them, the synchronous and co-directional displacement of the four struts 24 can ensure the stability and consistency of the outer attachment plate 21 during adjustment, better adapt to different models of the drainage bag body 104, and provide a reliable guarantee for the stable hanging and shielding protection of the drainage bag body 104.

[0050] For the above-mentioned micro biaxial motor, its working principle is well-known to those skilled in the art. In the micro biaxial motor, due to having two output shafts, its internal structure is specially designed so that the rotating magnetic field can drive the two output shafts to rotate at the same speed and in the same direction simultaneously. This kind of motor is small in size and moderate in power, and is suitable for occasions with specific requirements for space and power. For example, in the above-mentioned hanging mechanism 1, while stably driving the fine adjustment of the outer attachment plate 21, the self-gravity of the micro biaxial motor will not affect the adsorption and fixation effect of the hanging mechanism 1.

[0051] The above-mentioned micro lead screw 224 is a miniaturized lead screw drive device that can achieve precise linear motion control. Its surface pitch is small. The pitch of a common micro lead screw 224 can be between 0.1 mm and 1 mm, which can control the movement of the connecting rod 225 more precisely.

[0052] After the drainage bag body 104 is hung up, the outer attachment plate 21 can adsorb on the outside of the drainage bag body 104 to further fix it. Therefore, in order to further improve the protection accuracy of the outer attachment plate 21 for the drainage bag body 104, a dredging group 23 is installed on the surface of the outer attachment plate 21 close to the vertical fitting plate 112. The dredging group 23 includes a first semi-circular rod 231 and a second semi-circular rod 232. Both the first semi-circular rod 231 and the second semi-circular rod 232 are installed on the side of the outer attachment plate 21 close to the vertical fitting plate 112, and a limiting cavity 233 is formed between the first semi-circular rod 231 and the second semi-circular rod 232.

[0053] As Figure 7 shown, the dredging group 23 is composed of a first semi-circular rod 231 and a second semi-circular rod 232. They are both fixedly installed on the side of the outer attachment plate 21 close to the vertical fitting plate 112, and a limiting cavity 233 is formed between the first semi-circular rod 231 and the second semi-circular rod 232. Combined Figure 3As shown, when the fluid drained by the drainage member 101 has moderate fluidity, this limiting cavity 233 is used to limit the connecting pipe fitting 103 of the drainage bag body 104. On the one hand, it can reduce the excessive bending or displacement of the connecting pipe fitting 103 during use, ensuring the smooth progress of drainage. On the other hand, limiting the connecting pipe fitting 103 can improve the fixing effect of the outer attachment plate 21 on the drainage bag body 104, enhancing the stability of the drainage bag body 104 after hanging. At the same time, it helps to improve the protection accuracy of the outer attachment plate 21 for the drainage bag body 104, reducing the occurrence of unexpected situations that may be caused by the loosening or displacement of the connecting pipe, and providing a more reliable guarantee for the treatment of patients.

[0054] It should be noted that when the fluid drained by the drainage member 101 has moderate fluidity, the connecting pipe fitting 103 needs to be placed in the middle position between the first semi-circular rod 231 and the second semi-circular rod 232. At this time, the first semi-circular rod 231 and the second semi-circular rod 232 are in a non-fitting state with the connecting pipe fitting 103, which does not affect the drainage effect. If the hanging ring of the drainage bag body 104 is not aligned with the drainage bag body 104, the specific position of the limiting cavity 233 can be adjusted through the driving group 22.

[0055] When the fluid drained by the drainage member 101 is a thick liquid such as pus, the micro double-shaft motor can be started. The start of the micro double-shaft motor can drive the outer attachment plate 21 to continuously perform left and right fine-tuning. During this fine-tuning process, the first semi-circular rod 231 and the second semi-circular rod 232 will squeeze the surface of the connecting pipe fitting 103 as the outer attachment plate 21 moves (the extrusion force can be adjusted according to the conveying situation). After the first semi-circular rod 231 slides to squeeze the connecting pipe fitting 103, the outer attachment plate 21 slides in the reverse direction and continues to squeeze the other side of the connecting pipe fitting 103 through the second semi-circular rod 232. This cycle is repeated to achieve the effect of cyclic extrusion and dredging. Through extrusion, it helps to push the thick liquid smoothly through the connecting pipe fitting 103, reducing the stagnation at the interface due to the viscosity of the liquid, thereby reducing the risk of blockage;

[0056] The reason why the first semi-circular rod 231 and the second semi-circular rod 232 can play a role in dredging the pipeline by slightly squeezing the surface of the connecting pipe fitting 103 is that by squeezing the surface of the connecting pipe fitting 103, a certain pressure can be applied to the thick liquid, prompting the liquid to overcome the flow resistance and pushing the liquid forward. This extrusion is like giving the liquid an extra driving force to help the thick liquid smoothly pass through the interface, thereby reducing the occurrence of blockage situations and ensuring the smooth progress of the drainage process.

[0057] Among them, cyclic extrusion dredging is achieved by the forward and reverse rotation of the micro biaxial motor. Controlling the micro biaxial motor can control the rotation direction of the micro lead screw 224, and then accurately control the extrusion position and extrusion force of the first semi-circular rod 231 and the second semi-circular rod 232.

[0058] During the adsorption process of micro-nano materials, if there is enclosed air, the adsorption effect will be reduced. While the outer attachment plate 21 slides slightly left and right, the support rod 24 can also drive the first adsorbent 12 made of micro-nano materials to slide in the placement groove 13. By the slight sliding of the first adsorbent 12, air can be discharged, enabling it to fit more closely to the surface of the bed edge rod 10, thereby further improving the adsorption effect.

[0059] At the same time, through the setting of the inner diameter of the wide hole 4, the sliding position of the outer attachment plate 21 can be restricted, avoiding the situation that the first semi-circular rod 231 or the second semi-circular rod 232 is displaced excessively and affects the liquid flow inside the connecting pipe fitting 103.

[0060] According to the above content, the outer attachment plate 21 can cover the upper surface of the drainage bag body 104. When draining thick liquid, the outer attachment plate 21 needs to be adjusted left and right cyclically to achieve the extrusion and dredging of the connecting pipe fitting 103. In order to prevent the drainage bag body 104 from sliding along with the outer attachment plate 21 when the outer attachment plate 21 slides left and right, two extension support plates 3 are clamped and connected to the inner wall of the side of the outer attachment plate 21 close to the vertical fitting plate 112. The first semi-circular rod 231 and the second semi-circular rod 232 are located between the two extension support plates 3.

[0061] The improvement lies in: Combining Figure 7 it can be seen that the extension support plate 3 can provide additional support and fixed points for the outer attachment plate 21. When the outer attachment plate 21 is installed, the other end of the extension support plate 3 can be clamped at the edge of the upper end of the drainage bag body 104, further limiting and fixing the drainage bag body 104 while not affecting the drainage use of the drainage bag body 104. As Figure 5 shown, when the outer attachment plate 21 is adjusted left and right, the extension support plate 3 slides accordingly, and still can clamp and fix the upper edge of the drainage bag body 104, so that the drainage bag body 104 will not move along with the outer attachment plate 21 during the adjustment process, providing a more stable and safe drainage environment for the treatment of patients.

[0062] In summary, the working principle of this solution is as follows: First, the second adsorbent 14 fixedly connected to the surface of the horizontal fitting plate 111 and the first adsorbent 12 arranged on the surface of the vertical fitting plate 112 enable the horizontal fitting plate 111 and the vertical fitting plate 112 to be adsorbed on the surface of the bed edge rod 10 by means of the first adsorbent 12 and the second adsorbent 14. Then, the hook ring of the drainage bag body 104 is hung on the surface of the hanging rod body 113 in the middle. After the drainage bag body 104 is hung up, the outer attachment plate 21 can effectively externally shield the drainage bag body 104, which can greatly improve the hanging stability of the drainage bag body 104. At the same time, through the shielding of the outer attachment plate 21, the entry of dust and impurities into the connecting pipe fitting 103 can be significantly reduced, keeping the connecting pipe fitting 103 clean and reducing the risk of infection or blockage caused by the entry of dust and impurities;

[0063] When the fluidity of the liquid drained by the drainage member 101 is moderate, the limiting cavity 233 formed between the first semi-circular rod 231 and the second semi-circular rod 232 is used to limit the connecting pipe fitting 103 of the drainage bag body 104. On the one hand, it can reduce the excessive bending or displacement of the connecting pipe fitting 103 during use, ensuring the smooth progress of drainage. On the other hand, limiting the connecting pipe fitting 103 can improve the fixing effect of the outer attachment plate 21 on the drainage bag body 104, enhancing the stability of the drainage bag body 104 after hanging. At the same time, it helps to improve the protection accuracy of the outer attachment plate 21 for the drainage bag body 104 and reduce the occurrence of unexpected situations that may be caused by the loosening or displacement of the connecting pipe;

[0064] When the liquid drained by the drainage member 101 is a highly viscous liquid such as pus, the micro double-shaft motor can be started. The start of the micro double-shaft motor can drive the outer attachment plate 21 to continuously make left and right fine adjustments. During this fine adjustment process, the first semi-circular rod 231 and the second semi-circular rod 232 will slightly squeeze the surface of the connecting pipe fitting 103 as the outer attachment plate 21 moves. After the first semi-circular rod 231 slides to slightly squeeze the connecting pipe fitting 103, the outer attachment plate 21 slides in the reverse direction and continues to slightly squeeze the other side of the connecting pipe fitting 103 through the second semi-circular rod 232. This process is repeated in a cycle to achieve the effect of cyclic extrusion and dredging. Through extrusion, it helps to push the thick liquid to smoothly pass through the connecting pipe fitting 103, reducing the stagnation at the interface due to the viscosity of the liquid, thereby reducing the risk of blockage.

[0065] The foregoing has shown and described the basic principles, main features and advantages of the present invention.
