Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to an improved drainage device. Background Art

[0002] When treating a patient, pus, blood or other fluids accumulated in human tissues or body cavities need to be drained out of the patient's body. The drainage method includes placing the catheter of the drainage bag into the wound cavity or body cavity to automatically drain the accumulated fluid (which can be called drainage fluid) in the wound cavity or body cavity. As the drainage action proceeds, the drainage fluid in the drainage bag gradually increases. When the drainage fluid in the drainage bag accumulates to a certain level, it is necessary to drain the drainage fluid in the drainage bag and continue drainage or stop drainage directly. The volume change of the drainage fluid in the drainage bag needs to be monitored in real time by medical staff.

[0003] See also Figure 1 As shown, Figure 1 It is a structural diagram of an alarm device for observing the drainage of peritoneal dialysis fluid in the prior art. The existing Chinese patent document (CN219167281U, authorization announcement date June 13, 2023) discloses an alarm device for observing the drainage of peritoneal dialysis fluid, including a drainage bag 1' and an alarm system; the upper end of the drainage bag 1' is connected to a drainage tube 11', and the upper end of the drainage bag 1' is provided with a mounting sleeve 12' whose two ends are respectively connected to the inside and outside of the drainage bag 1'; the alarm system includes a sensor 21' and an alarm circuit, the sensor 21' is detachably mounted in the mounting sleeve 12', and the lower end of the sensor 21' is provided with a positive electrode extending into the drainage bag 1' and negative electrode, the upper end of the sensor 21' is provided with a positive terminal 211' and a negative terminal 212' extending out of the drainage bag 1', the positive terminal 211' is connected to the positive electrode, and the negative terminal 212' is connected to the negative electrode, and the positive terminal 211' and the negative terminal 212' are respectively connected to the alarm circuit; the upper end of the mounting sleeve 12' is provided with a locking sleeve section extending out of the drainage bag 1', the locking sleeve section can be deformed in the radial direction, and the outer sleeve of the sensor 21' is provided with a locking nut 213', the locking nut 213' is tightened outside the locking sleeve section, and squeezes the locking sleeve section inward to clamp the sensor 21' passing through the locking sleeve section. In this solution, the positive electrode and negative electrode of the sensor 21' need to be inserted into the drainage fluid. During the repeated use of the alarm system, the positive electrode and the negative electrode must be cleaned each time before use. This not only increases the workload of medical staff, but also, if the positive electrode and the negative electrode cannot be cleaned, there will be a problem of contaminating the drainage fluid. At the same time, the alarm system does not have a lighting function and cannot be used in dim conditions.

[0004] Another example is the application document with patent authorization announcement number CN221636850U and authorization announcement date September 3, 2024. It discloses a chest drainage device that can be installed with drainage catheters of different numbers and diameters through the connecting tube on the cover and the three-way stopcock used in conjunction with the connecting tube. The chest drainage device cannot perform drainage work under dim conditions, and there is no alarm function during drainage. The application document with patent authorization announcement number CN221636866U and authorization announcement date September 3, 2024. It discloses a negative pressure drainage device that ensures smooth drainage inside the drainage tube by setting a protective component and improves stability during drainage by setting a positioning component. The negative pressure drainage device cannot perform drainage work under dim conditions, and there is no alarm function during drainage. The patent authorization announcement number is CN221557019U and the application document with the authorization announcement date of August 20, 2024. It discloses a drainage device. When the drainage bag is replaced, bacteria will not enter the patient's body along with the drainage tube. The end of the drainage tube that contacts the drainage bag is always kept lower than the other end. There is no need to manually squeeze and clear the drainage tube when it is blocked. The drainage device cannot perform drainage work under dim conditions, and there is no alarm function during drainage.

[0005] Other patent documents such as patent publication numbers CN116407695A, CN111420135A, CN116688255A, and CN220256855U, although the patent names are similar to the name of this case, their structures, contents, and technical problems they solve are completely different from those of this application. They cannot solve the problems of how to perform drainage work under dim conditions and how to reduce the burden on medical staff while performing drainage work.

[0047] Example 1

[0048] Reference Figure 2 As shown, this embodiment provides an improved drainage device, including a drainage bag 1 and a connecting frame 2. The connecting frame 2 is clamped on a portion of the drainage bag 1, and the connecting frame 2 and the drainage bag 1 are detachably connected. The drainage bag 1 is used to drain and contain oozing blood, accumulated fluid, etc. in the patient's body. These liquids can be collectively referred to as drainage fluid. The connecting frame 2 has the functions of illuminating the drainage bag 1 and monitoring the real-time situation of the drainage fluid in the drainage bag 1.

[0049] Combine Figure 2-Figure 4As shown, along the thickness direction X of the drainage bag 1, the drainage bag 1 includes a front half bag 1a and a back half bag 1b that are relatively arranged. The front half bag 1a and the back half bag 1b can both be rectangular thin sheet structures. The length and width of the front half bag 1a and the back half bag 1b are the same. The front half bag 1a and the back half bag 1b are attached to each other to form the drainage bag 1. The drainage bag 1 includes a liquid holding area 11. The liquid holding area 11 is located at the middle of the front half bag 1a and the middle of the back half bag 1b at the same time. Along the thickness direction X of the drainage bag 1, the orthographic projection of the liquid holding area 11 is located within the orthographic projection of the drainage bag 1. The periphery of the liquid holding area 11 is provided with a sealing edge 12. The sealing edge 12 can be formed by pasting the edge of the front half bag 1a and the edge of the back half bag 1b. The edge 12 completely covers and seals the liquid holding area 11. When the liquid holding area 11 does not contain drainage fluid, the drainage bag 1 can also be a rectangular thin sheet structure. Along the thickness direction X of the drainage bag 1, the shape of the orthographic projection of the liquid holding area 11 can be rectangular, and the shape of the sealing edge 12 can be annular (annular geometric figure). When the liquid holding area 11 contains drainage fluid, the liquid holding area 11 expands, and the structure of the sealing edge 12 remains unchanged. It should be noted that, in this embodiment, the thickness direction X of the drainage bag 1 refers to the thickness direction X when the liquid holding area 11 does not contain drainage fluid. At this time, the drainage bag 1 is a rectangular thin sheet structure. At the same time, the thickness direction X of the drainage bag 1 can also be understood as the direction from the front half bag 1a to the back half bag 1b.

[0050] Reference Figure 4 As shown, the sealing edge 12 includes an upper sealing edge 121, a left sealing edge 122, a lower sealing edge 123 and a right sealing edge 124 connected end to end in sequence, the upper sealing edge 121 is connected to the side away from the left sealing edge 122 and the right sealing edge 124 is connected to the side away from the lower sealing edge 123, the upper sealing edge 121 and the lower sealing edge 123 are arranged oppositely and parallel to each other, the left sealing edge 122 and the right sealing edge 124 are arranged oppositely and parallel to each other, and the upper sealing edge 121 and the lower sealing edge 123 are arranged along the width of the drainage bag 1. The left sealing edge 122 and the right sealing edge 124 extend upward in the direction Y and are arranged along the length direction Z of the drainage bag 1. The width direction Y of the drainage bag 1, the length direction Z of the drainage bag 1 and the thickness direction X of the drainage bag 1 intersect with each other in pairs. Optionally, the width direction Y of the drainage bag 1, the length direction Z of the drainage bag 1 and the thickness direction X of the drainage bag 1 are perpendicular to each other in pairs. The left sealing edge 122 and the right sealing edge 124 extend along the length direction Z of the drainage bag 1 and are arranged along the width direction Y of the drainage bag 1.

[0051] Continue to refer to Figure 4As shown, a drainage tube 13 is sleeved on the upper sealing edge 121. The drainage tube 13 is fixedly connected to the upper sealing edge 121. The drainage tube 13 extends along the length direction Z of the drainage bag 1 and is connected to the liquid containing area 11. The drainage tube 13 has a certain length and is used to communicate with a urinary catheter or an in-vivo drainage tube, etc. The urinary catheter or the in-vivo drainage tube, etc. is used to be inserted into the patient's body to drain the accumulated fluid in the patient's body out of the body. The accumulated fluid drained out of the patient's body flows through the drainage tube 13 and finally flows into the liquid containing area 11 of the drainage bag 1 to become the drainage fluid.

[0052] Continue to refer to Figure 4 As shown, a liquid discharge tube 14 is sleeved on the lower sealing edge 123. The liquid discharge tube 14 is fixedly connected to the lower sealing edge 123. The liquid discharge tube 14 extends along the length direction Z of the drainage bag 1 and is connected to the liquid containing area 11. The liquid discharge tube 14 is used to discharge the drainage fluid in the liquid containing area 11.

[0053] Combined with Figure 2-Figure 3 As shown, the connecting frame 2 is clamped on a part of the upper sealing edge 121. Along the thickness direction X of the drainage bag 1, the orthographic projection of the drainage bag 1 and the orthographic projection of the connecting frame 2 at least partially overlap. The connecting frame 2 and the drainage bag 1 are detachably connected. This setting ensures that the connecting frame 2 can be quickly combined with or separated from the drainage bag 1, saving operation time. The connecting frame 2 can be reused multiple times. After the connecting frame 2 is removed from the previous drainage bag 1, the same connecting frame 2 can be directly assembled on the next drainage bag 1 without other redundant operations, reducing the work burden of medical staff. At the same time, the connecting frame 2 does not come into contact with the drainage fluid inside the drainage bag 1, which can avoid problems such as the need to clean the connecting frame 2 multiple times and the drainage fluid being contaminated.

[0054] Combined with Figure 3-Figure 5 As shown, the connecting frame 2 includes a rear clamping plate 21, an upper plate 22 and a rear plate 23 connected in sequence. The rear clamping plate 21, the upper plate 22 and the rear plate 23 can all be rectangular flat plate structures. The rear clamping plate 21, the upper plate 22 and the rear plate 23 enclose an approximately U-shaped structure. The opening of the U-shaped structure is located on the side facing the upper sealing edge 121. The upper plate 22 is located on the side of the rear clamping plate 21 away from the upper sealing edge 121. The rear clamping plate 21 and the rear plate 23 are parallel to each other and the plane where the rear clamping plate 21 is located is perpendicular to the thickness direction X of the drainage bag 1. The rear clamping plate 21 and the upper plate 22 are perpendicular to each other. Along the length direction Z of the drainage bag 1, the length of the rear clamping plate 21 is less than the length of the rear plate 23. The middle clamping plate 24 and the front clamping plate 25 are sequentially connected to the side of the rear clamping plate 21 away from the rear plate 23. The end of the middle clamping plate 24 away from the front clamping plate 25 is connected to the connection part of the rear clamping plate 21 and the upper plate 22. The middle clamping plate 24 can be a rectangular flat plate (such as Figure 3As shown) or the middle splint 24 can be an arc-shaped plate (not shown in the figure), when the middle splint 24 is an arc-shaped plate, along the width direction Y of the drainage bag 1, the orthographic projection of the middle splint 24 can be C-shaped, and the C-shaped opening is located on the side facing the drainage bag 1, and when the middle splint 24 is a rectangular flat plate, the middle splint 24 can be parallel to the upper plate 22, or the angle between the front splint 25 and the middle splint 24 is not greater than 90°, and the front splint 25 can be a rectangular flat plate, and the front splint 25, the middle splint 24 and the rear splint 21 cooperate with each other to clamp the connecting frame 2 on the drainage bag 1. When the connecting frame 2 is clamped on the drainage bag 1, along the thickness direction X of the drainage bag 1, the distance between the end of the front splint 25 close to the middle splint 24 and the end of the rear splint 21 close to the middle splint 24 is greater than the distance between the end of the front splint 25 away from the middle splint 24 and the end of the rear splint 21 away from the middle splint 24.

[0055] Combine Figure 3-Figure 5 As shown, a front accommodating space 201 is formed between the front splint 25, the middle splint 24 and the rear splint 21. The front accommodating space 201 can be an open structure. The front accommodating space 201 is used to accommodate part of the drainage bag 1. Part of the drainage bag 1 is clamped between the front splint 25 and the rear splint 21, which is manifested as part of the upper sealing edge 121 and part of the liquid holding area 11 being clamped between the front splint 25 and the rear splint 21. The side of the front splint 25 away from the middle splint 24 is in contact with the side of the rear splint 21 away from the middle splint 24. The side of the front splint 25 away from the middle splint 24 and the side of the rear splint 21 away from the middle splint 24 can be clamped to each other, so that the connecting frame 2 can be connected to the drainage bag 1.

[0056] Continue to combine Figure 3-Figure 5 As shown, when the connecting frame 2 is clamped on the drainage bag 1, along the thickness direction X of the drainage bag 1, the orthographic projection of part of the upper edge seal 121 is located within the orthographic projection of the front splint 25, and at the same time, the orthographic projection of part of the liquid holding area 11 is located within the orthographic projection of the front splint 25. This arrangement can maximize the contact area between the front splint 25 and the upper edge seal 121, as well as the contact area between the front splint 25 and the liquid holding area 11, thereby improving the connection strength between the connecting frame 2 and the drainage bag 1, and can also prevent the drainage bag 1 from falling off from the connecting frame 2.

[0057] Reference Figure 5As shown, a rear accommodating space 202 is formed between the rear splint 21, the upper plate 22 and the rear plate 23. A front protrusion 212 is provided on the side of the rear splint 21 close to the rear plate 23, and the front protrusion 212 can be located at the end of the rear splint 21. A rear protrusion 231 is provided on the side of the rear plate 23 close to the rear splint 21, which cooperates with the front protrusion 212. The rear protrusion 231 can be located in the middle of the rear plate 23. A lampshade 3 is clamped between the front protrusion 212 and the rear protrusion 231. The lampshade 3 is used to close the rear accommodating space 202 from the thickness direction X of the drainage bag 1 and from the length direction Z of the drainage bag 1. The lampshade 3 has the functions of collecting light, preventing dust from falling in the rear accommodating space 202, and protecting the rear accommodating space 202.

[0058] Combine Figure 3 and Figure 6 As shown, an alarm 4, a lighting lamp 5 and a battery 6 are provided in the rear storage space 202, and a light sensor 7 is connected to the surface of the rear plate 23 close to the rear splint 21, and the light sensor 7 is located on the side of the rear protrusion 231 away from the rear storage space 202, and the light sensor 7 is fixedly connected to the rear plate 23, and the alarm 4, the battery 6 and the light sensor 7 are electrically connected to each other. It can be understood that the alarm 4 and the battery 6 are electrically connected to each other, and at the same time, the alarm 4 and the light sensor 7 are electrically connected to each other, and the battery 6 and the light sensor 7 are electrically connected to each other. The battery 6 is used to provide power to the alarm 4 and the light sensor 7 respectively, ensuring the normal use of the alarm 4 and the light sensor 7. The light sensor 7 is used to control whether the alarm 4 is working. When the light sensor 7 controls the alarm 4 to work, the alarm 4 makes a sound to remind medical staff and patients. When the light sensor 7 controls the alarm 4 not to work, the alarm 4 does not make a sound.

[0059] Combine Figure 3-Figure 4 、 Figure 6 As shown, when the connecting frame 2 is clamped on the drainage bag 1, the orthographic projection of the optical sensor 7 is located within the orthographic projection of the liquid holding area 11 along the thickness direction X of the drainage bag 1. This arrangement ensures that the volume of the drainage fluid in the liquid holding area 11 can affect the use state of the optical sensor 7. Specifically, when there is no drainage fluid in the liquid holding area 11 or the volume of the drainage fluid in the liquid holding area 11 does not exceed the warning line of the optical sensor 7, the optical sensor 7 is in a first sensing state, and at this time the optical sensor 7 does not control the alarm 4 to work; when the volume of the drainage fluid in the liquid holding area 11 exceeds the warning line of the optical sensor 7, the optical sensor 7 is in a second sensing state, and at this time the optical sensor 7 controls the alarm 4 to work.

[0060] It should be noted that:

[0061] (1) The light sensor 7 is a sensing device mainly composed of a photosensitive element (not shown in the figure). It mainly adjusts its working state by monitoring the changes in light in the surrounding environment. It has the advantages of high precision and real-time automatic monitoring. Optionally, the light sensor 7 can be a digital ambient light sensor with a wide detection range, an output tolerance of less than 10%, and low wiring difficulty. Information on digital ambient light sensors can be found at the following link: https: / / ic-item.jd.com / 10092761516301.html.

[0062] (2) The warning line of the light sensor 7 can be set to the horizontal position of the photosensor 7 along the length direction Z of the drainage bag 1, and the photosensor 7 can automatically monitor the changes in the light nearby in real time. Since the drainage fluid is a colored liquid, when there is no drainage fluid in the liquid holding area 11 or the volume of the drainage fluid in the liquid holding area 11 does not exceed the warning line of the light sensor 7, the light near the photosensor does not change. At this time, the light sensor 7 is in the first sensing state. When the volume of the drainage fluid in the liquid holding area 11 exceeds the warning line of the light sensor 7, the light near the photosensor changes significantly. At this time, the light sensor 7 is in the second sensing state. Therefore, by setting the photosensor 7, the volume of the drainage fluid in the liquid holding area 11 can be monitored in real time.

[0063] Reference Figure 3 As shown, the alarm 4 can be arranged on the side of the rear splint 21 close to the rear plate 23, and the alarm 4 and the rear splint 21 can be fixedly connected by welding, bonding, etc., and the battery 6 can be arranged between the upper plate 22 and the rear plate 23, and the battery 6 and the upper plate 22 can be fixedly connected by welding, bonding, etc., and at the same time, the battery 6 and the rear plate 23 can be fixedly connected by welding, bonding, etc.; the above describes an installation position and installation method of the alarm 4 and the battery 6 in the rear storage space 202 respectively. In other embodiments, the installation position and installation method of the alarm 4 and the battery 6 in the rear storage space 202 can be adaptively adjusted according to actual conditions, and are not specifically limited here; optionally The alarm 4 can be an active buzzer, which is triggered by a low level and has an operating voltage range of 3.3V-5V. It is equipped with a fixing bolt hole for easy installation. The product size is 3.2cm×1.3cm.

[0064] Combine Figure 3 and Figure 6 As shown, the illuminating lamp 5 is electrically connected to the battery 6, and the battery 6 is used to provide electricity for the illuminating lamp 5 and control whether the illuminating lamp 5 is working. When the battery 6 provides electricity for the illuminating lamp 5, the illuminating lamp 5 is in a working state, and the illuminating lamp 5 emits light, which can be emitted through the lampshade 3. When the battery 6 does not provide electricity for the illuminating lamp 5, the illuminating lamp 5 is in a non-working state, and the illuminating lamp 5 does not emit light. The illuminating lamp 5 can be set on the back plate 23, and the illuminating lamp 5 and the back plate 23 can be fixedly connected by bonding, welding, clamping, etc. The illuminating lamp 5 can be located between the battery 6 and the rear protrusion 231, and the illuminating lamp 5 is close to the lampshade 3. This arrangement can ensure that when the illuminating lamp 5 is working, there is enough light emitted through the lampshade 3, and the light emitted through the lampshade 3 can illuminate the drainage bag 1. This helps medical staff or patients to see the situation of the drainage bag 1, including but not limited to whether the liquid in the drainage tube 13 flows into the liquid holding area 11, the flow rate of the liquid in the drainage tube 13, the volume of the drainage liquid in the liquid holding area 11, etc.; the above describes an installation position and installation method of the lighting lamp 5 in the rear holding space 202. In other embodiments, the installation position and installation method of the lighting lamp 5 in the rear holding space 202 can be adaptively adjusted according to actual conditions, and no specific limitation is made here; optionally, the lighting lamp 5 can be a light strip, which can be freely cut, has its own adhesive backing, and has good waterproof effect. Information about the light strip can be found in the following link: https: / / item.jd.com / 10083602565822.html.

[0065] It should also be emphasized that the main material of the connecting frame 2 needs to be set to a dark color. This setting ensures that the connecting frame 2 isolates the external ambient light except the light emitted by the lighting lamp 5 for the light sensor 7 as much as possible, thereby improving the accuracy of the light monitoring results of the light sensor 7.

[0066] During specific use, the drainage bag 1 is connected to the urinary catheter or internal drainage tube in the patient's body through the drainage tube 13, the connecting frame 2 is clamped on part of the upper sealing edge 121 and part of the liquid holding area 11, and the lighting lamp 5 is turned on, so that medical staff, the patient himself or the patient's family can see the drainage bag 1 clearly and clearly understand the progress of the current drainage work. When the volume of the drainage fluid in the liquid holding area 11 does not exceed the warning line of the light sensor 7, the light sensor 7 is in the first sensing state. At this time, the light sensor 7 does not control the alarm 4 to work. When the volume of the drainage fluid in the liquid holding area 11 exceeds the warning line of the light sensor 7, the light sensor 7 is in the second sensing state. At this time, the light sensor 7 controls the alarm 4 to work, and the alarm 4 sounds to remind medical staff, the patient himself or the patient's family that the volume of the drainage fluid in the liquid holding area 11 is too large, and it is necessary to discharge the drainage fluid through the drainage tube or directly replace the new drainage bag 1 to continue the drainage work.

[0067] Example 2

[0068] This embodiment is an extension of the first embodiment.

[0069] Reference Figure 2 As shown, this embodiment provides an improved drainage device, including a drainage bag 1 and a connecting frame 2. The connecting frame 2 is clamped on a portion of the drainage bag 1, and the connecting frame 2 and the drainage bag 1 are detachably connected. The drainage bag 1 is used to drain and contain oozing blood, accumulated fluid, etc. in the patient's body. These liquids can be collectively referred to as drainage fluid. The connecting frame 2 has the functions of illuminating the drainage bag 1 and monitoring the real-time situation of the drainage fluid in the drainage bag 1.

[0070] Continue to refer to Figure 2 As shown, the main body material of the drainage bag 1 can be selected from plastic or rubber, and the plastic material can be polyethylene or polypropylene. Polyethylene (English: Polyethylene, abbreviated as: PE) has the advantages of high corrosion resistance, strong impact resistance, high electrical insulation performance, strong chemical stability, softness, leakage prevention and easy processing and molding. Polypropylene (English: Polypropylene, abbreviated as: PP) has the advantages of good chemical resistance and heat resistance, high strength mechanical properties and wear resistance, softness, leakage prevention and easy processing and molding. The rubber material can be silicone. Silicone has the advantages of strong chemical resistance, permeability resistance and large capacity, resistance to high temperature and high pressure sterilization, and can be reused. The materials that can be selected for the main body of the drainage bag 1 include but are not limited to these, and no specific restrictions are made here; in addition, the state of the drainage bag 1 can be transparent or translucent. This setting is to facilitate medical staff to see the situation inside the drainage bag 1 from the outside to avoid problems such as excessive drainage fluid or even backflow.

[0071] Continue to refer to Figure 4As shown, a drainage tube 13 is sleeved on the upper sealing edge 121, and the end of the drainage tube 13 away from the liquid holding area 11 is connected to a joint (not shown in the figure). The shape of the joint can be a pagoda. The side of the joint away from the drainage tube 13 can be connected to a urinary catheter or an internal drainage tube, etc. The urinary catheter or the internal drainage tube is used to be inserted into the patient's body to discharge the accumulated fluid in the patient's body. The accumulated fluid discharged from the patient's body flows through the joint and the drainage tube 13 in turn, and finally flows into the liquid holding area 11 of the drainage bag 1 to become drainage fluid. The drainage tube 13 is outer-mounted with a flow rate switch (not shown in the figure), which is located between the joint and the drainage bag 1. The flow rate switch is used to regulate the flow rate of the liquid flowing through the drainage tube 13.

[0072] Continue to refer to Figure 4 As shown, a drain pipe 14 is sleeved on the lower sealing edge 123, and a drain valve 15 is connected to the end of the drain pipe 14 away from the liquid holding area 11. The drain valve 15 and the drain pipe 14 can be a plug-in connection structure or a spiral connection structure. The connection method between the drain valve 15 and the drain pipe 14 is not specifically limited here. When the drain valve 15 and the drain pipe 14 are connected in a plug-in connection structure, the medical staff, the patient himself or the patient's family members operate the drain valve 15 to move to the side away from the drain pipe 14, and the drain valve 15 conducts the drain pipe. 14. The drainage liquid in the liquid holding area 11 flows out through the drain pipe 14 and the drain valve 15 in sequence, thereby draining the drainage liquid in the drainage bag 1. The medical staff or the patient himself operates the drain valve 15 to move it to the side close to the drain pipe 14. The drain valve 15 closes the drain pipe 14, and the drainage liquid in the liquid holding area 11 cannot flow out through the drain pipe 14 and the drain valve 15. The drainage pipe 14 and the drain valve 15 cooperate with each other to complete the control of the drainage liquid volume in the drainage bag 1, ensuring the continuous use of the same drainage bag 1.

[0073] Combine Figure 2-Figure 4 As shown, a plurality of capacity scale lines 1a1 are provided on the surface of the front half bag 1a away from the back half bag 1b, and the plurality of capacity scale lines 1a1 are arranged along the length direction Z of the drainage bag 1. A capacity mark (not shown in the figure) is provided at the position corresponding to each capacity scale line 1a1. The capacity mark is used to display the volume of the drainage fluid when the horizontal plane of the drainage fluid in the liquid holding area 11 reaches this position. The capacity mark can be 5ml, 10ml, 15ml, 20ml, 25ml, 30ml... etc. Along the length direction Z of the drainage bag 1, the shorter the distance between the capacity mark and the drainage tube 13, the larger the value of the capacity mark, and the longer the distance between the capacity mark and the drainage tube 13, the smaller the value of the capacity mark. Similarly, the shorter the distance between the capacity mark and the drainage tube 14, the smaller the value of the capacity mark, and the longer the distance between the capacity mark and the drainage tube 14, the larger the value of the capacity mark.

[0074] Reference Figure 4 As shown, the upper sealing edge 121 is connected with a hanging belt 16, which is used to control the position of the drainage bag 1. The hanging belt 16 can be directly hung on the hook on the side of the bed. Medical staff or patients can also pull the hanging belt 16 by hand, so as to facilitate the patient to walk with the drainage bag 1. The hanging belt 16 can be a semi-circular structure, and the opening of the semi-circular ring is facing the side close to the upper sealing edge 121. The two ends of the hanging belt 16 are fixedly connected to the upper sealing edge 121. This arrangement ensures the stability of the overall structure of the drainage bag 1; in the liquid holding area 1 When the drainage bag 1 does not contain liquid, the drainage bag 1 has a long side symmetry axis m, and the left sealing edge 122 and the right sealing edge 124 are symmetrically arranged about the long side symmetry axis m. The extension direction of the long side symmetry axis m is the same as the length direction Z of the drainage bag 1. The hanging belt 16 is symmetrical about the long side symmetry axis m. This arrangement ensures that when the drainage bag 1 is hung or pulled, the two ends of the hanging belt 16 provide the same pulling force to the upper sealing edge 121, ensuring the balance of the hanging belt 16 when controlling the drainage bag 1, and avoiding problems such as drainage liquid backflow due to the drainage bag 1 being skewed or tilted.

[0075] Continue to refer to Figure 4 As shown, the drainage tube 13 itself is symmetrical about the long side symmetry axis m, which can be understood as the drainage tube 13 is located in the middle of the upper sealing edge 121, and the drainage tube 14 is symmetrical about the long side symmetry axis m, which can be understood as the drainage tube 14 is located in the middle of the lower sealing edge 123. The positions of the drainage tube 13 and the drainage tube 14 are arranged in this way to ensure the stability of the overall structure of the drainage bag 1, and at the same time ensure the balance of the liquid holding area 11 when collecting or discharging liquid, avoiding the problem of the drainage bag 1 being skewed or tilted, causing the drainage liquid to flow back.

[0076] Reference Figure 2 As shown, the material that can be selected for the main body of the connecting frame 2 includes but is not limited to plastic. Plastic has the advantages of easy processing, long service life, low cost, and light weight. The material that can be selected for the main body of the connecting frame 2 includes but is not limited to this, and no specific limitation is made here.

When the number of the front clamping protrusions 251 is multiple, the multiple front clamping protrusions 251 can be arranged along the length direction Z of the drainage bag 1, and the rear splint 21 is provided with at least one rear clamping protrusion 211 on the side away from the middle splint 24, and the rear clamping protrusion 211 is located on the surface of the rear splint 21 close to the front splint 25. When the number of the rear clamping protrusions 211 is multiple, the multiple rear clamping protrusions 211 can be arranged along the length direction Z of the drainage bag 1. When the connecting frame 2 is clamped on the drainage bag 1, the front clamping protrusion 251 is snapped into the adjacent rear clamping protrusions The protrusions 211 are connected between the rear clamping protrusions 211 and the adjacent front clamping protrusions 251. The rear clamping protrusions 211 and the front clamping protrusions 251 cooperate with each other to ensure that the front splint 25 is away from the side of the middle splint 24 and the rear splint 21 is away from the side of the middle splint 24, thereby preventing the drainage bag 1 from falling off the connecting frame 2. It should be noted that when the position of the rear splint 21 is fixed, medical staff can manually change the position of the front splint 25 so that the rear clamping protrusions 211 and the front clamping protrusions 251 are connected to or separated from each other, thereby ensuring the installation or disassembly between the connecting frame 2 and the drainage bag 1. The connecting frame 2 has a certain strength and the overall structure is stable.

The structure of the middle lampshade 31 can be approximately an arc-shaped plate structure. The arc-shaped plate protrudes toward the side away from the rear accommodating space 202. The approximate plane where the middle lampshade 31 is located has a certain angle with the length direction Z of the drainage bag 1. It can be understood that the approximate plane where the middle lampshade 31 is located is not parallel to the plane where the upper plate 22 is located. Along the length direction Z of the drainage bag 1, the distance between the end of the middle lampshade 31 close to the rear splint 21 and the upper plate 22 is smaller than the distance between the end of the middle lampshade 31 close to the rear plate 23 and the upper plate 22. This arrangement ensures that the light collected by the lampshade 3 is emitted toward the side away from the upper plate 22 and the side away from the rear plate 23 at the same time; along the drainage bag 1, the plane where the rear plate 23 is located is the dividing interface, the side of the rear plate 23 close to the rear accommodating space 202 is the first area A, and the side of the rear plate 23 away from the rear accommodating space 202 is the second area B.

The right closing piece prevents dust from falling in the rear accommodating space 202 and protects the rear accommodating space 202. The rear accommodating space is completely sealed by the left closing piece, the right closing piece and the lampshade 3. While protecting the rear accommodating space 202, the overall structure of the connecting frame 2 is simple and integrated.

As long as it is ensured that the light switch 221 can control whether the lighting lamp 5 emits light, the installation position of the light switch 221 and the installation method of the light switch 221 on the mounting frame 2 can be adaptively adjusted according to actual conditions, and no specific limitation is made here.

[0085] Continue to combine Figure 2-Figure 3 、 Figure 6As shown, the battery power indicator light 222 is used to be electrically connected to the battery 6. The battery power indicator light 222 can emit lights of different colors and states to reflect the power status of the battery 6. The power status includes insufficient power, gradually increasing power, and full power. Regarding the use of the battery power indicator light 222, please refer to the following: when the battery power indicator light 222 emits a flashing red light, it means that the battery 6 is insufficient and needs to be charged. The USB interface can be electrically connected to an external power source through a data cable. During the charging process of the battery 6, the battery power indicator light 222 emits a flashing green light, indicating that the battery 6 is in In the charging state, the power of the battery 6 gradually increases; when the battery 6 is fully charged, the battery power display light 222 emits a constant green light, indicating that the battery 6 is now fully charged and the connection between the USB interface and the external power supply can be disconnected; the above describes an installation position of the battery power display light 222 and an installation method of the battery power display light 222 on the mounting bracket 2.
