Description

A drainage device for intensive care unit Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a drainage device for use in intensive care unit. Background Technology

[0002] Some patients develop fluids in their body cavities that cannot be drained normally due to illness or surgery, such as pleural or abdominal drainage fluid, pus, blood, and pericardial effusion. In such cases, medical personnel usually treat patients by drainage to remove excess waste fluid from their bodies. Drainage refers to the act, process, and method of extracting fluid from a patient's body cavity using methods such as siphoning or negative pressure suction.

[0003] Existing negative pressure drainage devices are usually directly connected to the drainage bag, which means that the drained blood, fluid, urine and other bodily waste fluids may enter the negative pressure drainage device. This not only has an adverse effect on the negative pressure drainage device, but also requires cleaning before subsequent use to avoid cross-infection, which is time-consuming and laborious. In addition, the odor and bacteria carried by the above-mentioned waste fluids will be directly discharged into the air, which is not safe. Technical issues

[0004] To address the above problems, this invention provides a drainage device for intensive care medicine, which keeps the puncture site and the area around the drainage tube on the patient's body surface clean, as well as all components for auxiliary drainage, and prevents waste liquid from leaking. Technical solutions

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A drainage device for intensive care unit, including a base, and further comprising:

[0007] The container is disposed on the top of the base. The container has an internal cavity. The side of the container has a first through hole, a second through hole, and a negative pressure pump. The first through hole, the second through hole, and the negative pressure pump are all connected to the cavity. The side of the container is detachably connected to a door corresponding to the first through hole for opening and closing the first through hole.

[0008] A drainage tube, one end of which is inserted into the patient's body to drain fluid from the patient's body, and the other end of which is inserted into the inside of the container and detachably connected to a drainage bag. The inside of the drainage bag is vacuum-sealed, and a one-way valve is provided at the inlet of the drainage bag to prevent backflow of the fluid entering the drainage bag.

[0009] A sealing assembly is installed on the side of the container and is provided corresponding to the second through hole. It is used to seal the second through hole through which the drainage tube is inserted, and can cooperate with the box door to seal the cavity.

[0010] An exudate collection assembly is connected to the area surrounding a puncture site or drainage tube on the patient's body surface for drainage. The exudate collection assembly includes a collection cavity, a first opening, and a second opening. The first opening and the second opening are both connected to the collection cavity and are located on opposite sides of the collection cavity. The first opening corresponds to the area surrounding the puncture site or drainage tube, and the middle part of the drainage tube passes through the first opening and the second opening to allow fluid leaking from the puncture site or the area surrounding the drainage tube to enter the collection cavity.

[0011] Preferably, the sealing assembly includes:

[0012] A fastener is fixedly connected to the side of the container. The fastener is annular and concentric with the second through hole. The fastener has an external thread on its outer side.

[0013] A rotating component has a groove at one end, the groove being cylindrical and having an internal thread that can engage with the external thread.

The diameter of the fourth through hole is larger than the diameter of the drainage tube. The sealing gasket is made of elastic material. When the rotating member is rotated, the clamping member can press the sealing gasket so that the sealing gasket deforms and clamps the drainage tube, thereby sealing the second through hole.

[0015] Preferably, both the sealing gasket and the one-way valve are made of silicone.

[0016] Preferably, the exudate collection assembly includes;

[0017] A chassis, one end of which is attached to the patient's skin and the other end is provided with a ring-shaped first buckle. The first opening is opened in the middle of the chassis and is concentrically arranged with the first buckle.

[0018] The bag body has a second fastener corresponding to the first fastener on the side near the base. The collection cavity is located in the middle of the bag body, and the second opening is located on the side of the bag body away from the base. The second fastener is annular and communicates with the collection cavity. The base and the bag body can be fastened together by the cooperation of the first fastener and the second fastener, so that the liquid leaking from the puncture site or the area around the drainage tube can pass through the channel formed by the connection of the first opening, the first fastener and the second fastener in sequence, and finally enter the collection cavity.

[0019] Preferably, one end of the door is rotatably connected to the container. The cross-section of the first through hole is substantially rectangular. A rectangular annular frame is provided at the first through hole, and a rectangular annular sealing strip is provided on the outside of the frame. After the door is closed, it can abut against and press against the sealing strip to seal the first through hole. The container is provided with multiple limiting components for limiting and fixing the door after the first through hole is closed. The limiting components include:

[0020] A fixing base is fixedly connected to the container;

[0021] A limiting component is rotatably connected to the fixed base. The limiting component is basically elongated. During rotation, the limiting component is slidably connected to the container and slidably connected to the closed door with damping.

[0022] A protrusion is fixedly connected to the container and is provided corresponding to the container. The distance between the protrusion and the fixed base is less than the rotation radius of the limiting member. When the limiting member abuts against the protrusion, the extension direction of the limiting member is intersected with the vertical line so that the limiting member can rest on the protrusion and will not rotate on its own after being rested.

[0023] Preferably, the door of the container is provided with a viewing window for observing the internal condition of the container.

[0024] Preferably, the base is provided with multiple pulleys at its bottom for movement, and the base is also provided with a handle for gripping and assisting in movement.

[0025] Preferably, the base is provided with a storage box with multiple drawers for storing items, the base is provided with a trash can with an open top for recycling trash, and the top of the container is provided with a storage slot for placing items.

[0026] Preferably, the drainage tube comprises:

[0027] The first tube has one end that drains bodily fluids from the patient's body and can be connected to a drainage tube placed in the body cavity during surgery. The middle part of the first tube passes through the first opening, the collection chamber, and the second opening.

[0028] The second tube has one end inserted into the interior of the container and detachably connected to the drainage bag, and the other end detachably connected to the first tube. The middle part of the second tube passes through the second through hole.

[0029] Preferably, the diameter of the first tube is smaller than the diameter of the second tube, and the diameter of the second tube is smaller than the diameter of the joint where the one-way valve connects to the second tube, so as to prevent the flow of liquid from being obstructed. Beneficial effects

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] Because a special exudate collection component is installed around the puncture site or drainage tube to collect exudate, the skin near the puncture site or drainage tube can be kept dry and clean, which can effectively prevent infection and avoid subsequent cleaning of the skin and clothing.

[0032] Since this application drains fluid from the patient's body by changing the external air pressure of the drainage bag, the components used to assist drainage, such as the container and negative pressure pump, do not come into direct contact with the liquid. This allows these components to remain clean, eliminating the need for cleaning and preventing cross-infection when draining different patients.

[0033] Because the fluids in the patient's body go directly into the closed drainage bag through the drainage tube, and the exudate on the patient's body surface goes into the closed exudate collection component, these fluids will not come into contact with the outside world, and the odors produced will not be released into the air, making it safer and more reliable to use, and reducing the spread of pathogens and drug-resistant bacteria.

[0034] In summary, by using this intensive care unit drainage device, the puncture site and surrounding area of ​​the drainage tube on the patient's body surface can be kept clean, and waste fluid is less likely to leak, reducing the occurrence of adverse events such as cross-infection and nosocomial infection.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Referring to Figures 1-12, this embodiment of the invention discloses a drainage device for intensive care unit, including a base 1, a container 2, a drainage tube 3, a sealing assembly 4, and an exudate collection assembly 5. The container 2 is disposed on top of the base 1, and has an internal cavity 21. The side of the container 2 has a first through hole 22, a second through hole 23, and a negative pressure pump 6, all of which are connected to the cavity 21. A door 7 corresponding to the first through hole 22 is detachably connected to the side of the container 2 for opening and closing the first through hole 22. One end of the drainage tube 3 is inserted into the patient's body to drain fluid from the patient's body, and the other end of the drainage tube 3 is inserted into the container 2 and detachably connected to a drainage bag 8. The drainage bag 8 is vacuum-sealed, and a one-way valve 9 is provided at the inlet of the drainage bag 8. To prevent backflow of liquid entering the drainage bag 8; the sealing component 4 is installed on the side of the container 2 and is set corresponding to the second through hole 23, used to seal the second through hole 23 through which the drainage tube 3 is inserted, and can cooperate with the box door 7 to seal the cavity 21; the exudate collection component 5 is connected to the puncture site or the area around the drainage tube 3 on the patient's body surface for drainage, the exudate collection component 5 includes a collection cavity 51, a first opening 52, and a second opening 53, the first opening 52 and the second opening 53 are both connected to the collection cavity 51 and are respectively located on opposite sides of the collection cavity 51, the first opening 52 corresponds to the puncture site or the area around the drainage tube 3, and the middle part of the drainage tube 3 passes through the first opening 52 and the second opening 53, so that the liquid leaking from the puncture site or the area around the drainage tube 3 can enter the collection cavity 51.

[0051] In actual use, the base 1 is moved near the patient, and one end of the drainage tube 3 is passed sequentially through the second opening 53, the collection chamber 51, and the first opening 52, and finally inserted into the designated location in the patient's body. Then, the exudate collection component 5 is attached and fixed to the puncture site or the area around the drainage tube 3. The other end of the drainage tube 3 is passed through the second through hole 23 and inserted into the cavity 21 inside the container 2. Then, the drainage bag 8 is placed in the cavity 21 and connected to the drainage tube 3 through the one-way valve 9. After the connection is completed, the first through hole 2 is sealed through the box door 7. 2. By tightening the drainage tube 3 with the sealing component 4 and sealing the second through hole 23, the cavity 21 becomes a closed chamber. Then, the negative pressure pump 6 is turned on to draw negative pressure into the cavity 21, causing the drainage bag 8 to expand under the negative pressure and draw out the fluid from the patient's body. The fluid leaking from the puncture site or the area around the drainage tube 3 on the patient's body surface can enter the collection chamber 51 through the first opening 52. Since the puncture site or the area around the drainage tube 3 is equipped with a special exudate collection component 5 for receiving exudate, the puncture site can be... Keeping the skin around the drainage tube 3 dry and clean can effectively prevent infection and avoid subsequent cleaning of the skin and clothing. Since the fluid in the patient's body is drained by changing the external air pressure of the drainage bag 8, the components used to assist drainage, such as the container 2 and the negative pressure pump 6, do not come into direct contact with the fluid. This allows these components to remain clean, eliminating the need for cleaning and preventing cross-infection when draining different patients. Furthermore, since the fluid in the patient's body enters the sealed drainage bag 8 directly through the drainage tube 3, and the exudate on the patient's body surface enters the sealed exudate collection component 5, these fluids do not come into contact with the outside environment, and the resulting odor is not released into the air. This makes the device safer and more reliable, reducing the spread of pathogens and drug-resistant bacteria. In summary, by using this intensive care unit drainage device, the puncture site on the patient's body surface and the area around the drainage tube 3, as well as all the auxiliary drainage components, can be kept clean, and waste fluid is not easily leaked, reducing the occurrence of adverse events such as cross-infection and nosocomial infection.

[0052] It should be noted that this application does not limit the shape, size, material, or other parameters of container 2. It can be flexibly selected according to actual needs. For example, when the work space is large, a larger box can be used as container 2 to facilitate the placement of other items on top of container 2 and to facilitate various operations inside container 2. When the work space is small, such as when the ward is small or there are multiple beds in the ward, a smaller box can be used as container 2, which is not only easy to place but also more portable.

[0053] It is important to note that the first opening 52 and the second opening 53 should be sealed to prevent liquid from flowing out of the collection chamber 51. Specifically, the exudate collection component 5 and the area around the puncture site or drainage tube 3 on the patient's body surface should be sealed. There are various sealing methods, such as adhesive or the use of anti-leakage paste, so that the liquid leaking from the puncture site or the area around the drainage tube 3 can only enter the collection chamber 51 through the first opening 52. The second opening 53 and the drainage tube 3 should be sealed. The sealing method can be flexibly selected, such as adhesive or the use of anti-leakage paste, to prevent the liquid entering the collection chamber 51 from leaking out from the second opening 53.

[0054] It should be noted that the above-mentioned "various components for auxiliary drainage" specifically refers to other components besides the drainage tube 3, the exudate collection assembly 5, the drainage bag 8, and the one-way valve 9; the above-mentioned "side of container 2" includes the front, rear, left, right, top, and bottom of container 2.

[0055] Referring to Figures 1, 6, and 7, there are various structures capable of sealing between pipes and holes. To better understand how the relevant components in this application are sealed, this embodiment describes one design method. Specifically, the sealing assembly 4 includes a fixing member 41, a rotating member 42, and a sealing gasket 43. The fixing member 41 is fixedly connected to the side of the container 2. The fixing member 41 is annular and concentrically arranged with the second through hole 23. The outer side of the fixing member 41 is provided with an external thread 411. One end of the rotating member 42 is provided with a groove 421. The groove 421 is cylindrical and has an internal thread 422 that can engage with the external thread 411. The groove 421 is away from the fixing member 41. One end of the 1 is provided with a clamping block 44. The size of the clamping block 44 is smaller than the inner diameter of the annular fixing member 41. The middle of the groove 421 is provided with a third through hole 45 that passes through the rotating member 42 and the clamping block 44. The third through hole 45 is provided corresponding to the second through hole 23 and its diameter is larger than the diameter of the drainage tube 3. The sealing gasket 43 is located inside the fixing member 41. The sealing gasket 43 is cylindrical and has a fourth through hole 46 in the middle corresponding to the second through hole 23. The diameter of the fourth through hole 46 is larger than the diameter of the drainage tube 3. The sealing gasket 43 is made of elastic material. When the rotating member 42 is rotated, the clamping member can press the sealing gasket 43 to deform the sealing gasket 43 and tighten the drainage tube 3, thereby sealing the second through hole 23.

[0056] Through the design of the above structure, rotating component 42, with the cooperation of external thread 411 and internal thread 422, will also move along the extension direction of the axis of fixed component 41 during rotation, thereby causing the clamping block 44 to approach or move away from the sealing gasket 43; when the clamping block 44 moves away from the sealing gasket 43, the sealing gasket 43 is in its natural state, and the diameter of the fourth through hole 46 is slightly larger than the outer diameter of the drainage tube 3, so that the drainage tube 3 can pass through the fourth through hole 46; when the clamping block 44 approaches and clamps the sealing gasket 43, since the sealing gasket 43 is made of elastic material, the sealing gasket 43 will continuously deform during the clamping process, so that the inner wall of the annular sealing gasket 43, i.e., the diameter of the fourth through hole 46, becomes smaller, thereby tightening the drainage tube 3, and the outer wall of the annular sealing gasket 43 continuously increases in diameter and expands to abut against the inner wall of fixed component 41, so that the sealing gasket 43 presses against the outer surface of container 2, thereby completing the sealing of the second through hole 23.

[0057] Furthermore, the following design was also carried out in this embodiment: specifically, the sealing gasket 43 and the one-way valve 9 are both made of silicone.

[0058] Through the design of the above structure, both the sealing gasket 43 and the one-way valve 9 have a certain degree of elasticity, making the sealing gasket 43 easy to deform and the one-way valve 9 easy to insert and remove to connect pipes or joints. In addition, silicone is a material that is non-toxic and odorless, highly transparent, does not yellow, is soft, elastic, resistant to knotting and deformation, does not crack, has a long service life, is resistant to cold and high temperature, has high tear strength and excellent electrical properties, making it safer and more reliable in use.

[0059] Referring to Figures 1 and 8-10, in order to clearly understand the specific structure of the exudate collection component 5, the following design is made in this embodiment. Specifically, the exudate collection component 5 includes a base 54 and a bag body 55. One end of the base 54 is attached to the patient's skin, and the other end is provided with a ring-shaped first fastener 56. A first opening 52 is opened in the middle of the base 54 and is concentrically arranged with the first fastener 56. A second fastener 57 corresponding to the first fastener 56 is provided on the side of the bag body 55 near the base 54. A collection cavity 51 is opened in the middle of the bag body 55. A second opening 53 is opened on the side of the bag body 55 away from the base 54. The second fastener 57 is ring-shaped and communicates with the collection cavity 51. The base 54 and the bag body 55 can be fastened together by the cooperation of the first fastener 56 and the second fastener 57.

[0060] With the design of the above structure, the first opening 52 can be aligned with the puncture site or the area around the drainage tube 3 on the patient's body surface. Then, the base plate 54 is attached to the patient's skin. Subsequently, the base plate 54 and the bag body 55 are fastened together by the cooperation of the first fastener 56 and the second fastener 57. The drainage tube 3 passes through the first opening 52, the collection chamber 51, and the second opening 53, so that the liquid leaking from the puncture site or the area around the drainage tube 3 can pass through the channel formed by the connection of the first opening 52, the first fastener 56, and the second fastener 57, and finally enter the collection chamber 51. The above structure is similar to a two-piece ostomy bag. Based on the above scheme, after installing the exudate collection component 5, it can avoid exudate damage to the skin, reduce skin infection, accelerate wound healing, avoid odor, avoid staining clothing and bedding, and avoid frequent cleaning that would increase patient stress and frustration.

[0061] Referring to Figures 8 and 9, a drain port with a valve can be provided at the bottom of the bag 55 to prevent excessive liquid in the bag 55 from affecting the collection of seepage.

[0062] Referring to Figures 1, 3, and 5, there are various detachable connection methods and structures. This embodiment describes one such method. Specifically, one end of the door 7 is rotatably connected to the container 2. The cross-section of the first through hole 22 is basically rectangular. A rectangular annular frame 10 is provided at the first through hole 22. A rectangular annular sealing strip 11 is provided on the outside of the frame 10. After the door 7 is closed, it can abut against and press the sealing strip 11 to seal the first through hole 22. The container 2 is provided with multiple limiting components 12 for limiting and fixing the door 7 after the first through hole 22 is closed. The limiting component 12 includes a fixing seat 121, a limiting member 122, and a protrusion 1. 23. The fixed base 121 is fixedly connected to the container 2; the limiting member 122 is rotatably connected to the fixed base 121. The limiting member 122 is basically elongated. During rotation, the limiting member 122 is slidably connected to the container 2 and slidably connected to the closed door 7 with damping; the protrusion 123 is fixedly connected to the container 2 and is set corresponding to the container 2. The distance between the protrusion 123 and the fixed base 121 is less than the rotation radius of the limiting member 122. When the limiting member 122 abuts against the protrusion 123, the extension direction of the limiting member 122 is intersected with the vertical line so that the limiting member 122 can be placed on the protrusion 123 and will not rotate on its own after being placed.

[0063] With the above structural design, rotating the door 7 opens and closes the first through hole 22. When the door 7 is closed, the limiting member 122 rotates around the fixed base 121, so that the limiting member 122 rotates to the position corresponding to the first through hole 22, so that the limiting member 122 and the door 7 are connected with damping sliding. At this time, under the action of the limiting member 122, the door 7 can abut against and press the sealing strip 11 on the frame 10, so that the limiting member 122 can not only prevent the door 7 from opening automatically, but also press the door 7, thereby sealing the first through hole 22. When the door 7 needs to be opened, the limiting member 122 can be rotated to the protrusion 123. Since the limiting member 122 can be placed on the protrusion 123, the other hand does not need to maintain the stability of the limiting member 122 during the opening of the door 7, making it more convenient to use.

[0064] Referring to Figures 1 and 3, this embodiment also incorporates the following design: specifically, the door 7 is provided with a viewing window 13.

[0065] Through the design of the above structure, the internal condition of container 2 can be directly observed; in addition, the material of the viewing window 13 can be flexibly selected, such as high pressure resistant observation window glass. This material has the following advantages, such as being able to withstand a certain pressure, having a relatively thick thickness, high mechanical strength, high bending strength, high transparency, high visible light transmittance, excellent chemical stability, high electrical insulation and good thermal shock resistance.

[0066] Referring to Figures 1-3, since the intensive care unit drainage device in this application is reusable, it needs to be moved frequently when performing drainage operations on different patients. In order to facilitate the movement of the intensive care unit drainage device, the following design is made in this embodiment. Specifically, the bottom of the base 1 is provided with multiple pulleys 14 for movement, and the base 1 is also provided with a handle 15 for gripping and assisting movement.

[0067] It should be noted that the above-described design of the intensive care unit drainage device as a trolley structure is only one embodiment of this application. In actual use, since there are often multiple beds in a ward, the space near the beds is relatively small and it is not convenient to place large items. Therefore, the entire intensive care unit drainage device can also be designed as a small box structure for easy placement. For example, movable parts such as the drainage tube 3 and the exudate collection component 5 can be placed inside the container 2, and the negative pressure pump 6 can be placed inside the container 2. The size of the container 2 should be minimized as much as possible, and the entire intensive care unit drainage device should only appear as container 2 from the outside. This way, the intensive care unit drainage device can be designed as a portable box structure.

[0068] Referring to Figures 1-4, various tools are often needed during the drainage operation, and some garbage will inevitably be generated during the operation. Therefore, in order to assist the drainage, the following design is made in this embodiment. Specifically, the base 1 is provided with a storage box 16 with multiple drawers 161, the base 1 is provided with a garbage can 17 with an open top, and the top of the container 2 is provided with a storage slot 18 for placing items.

[0069] The above structure allows for the storage of items in the storage box 16, which can be used to store medical instruments and other commonly used instruments needed during the drainage procedure; waste can be recycled in the trash can 17, and a trash bag can be placed on the trash can 17 for easy cleaning; and items needed during the drainage procedure can be placed in the storage slot 18 on the top of the container 2 to facilitate the normal and rapid conduct of the drainage procedure.

[0070] Referring to Figures 1, 11, and 12, the drainage tube 3 is usually quite long, and it needs to pass through multiple components. If the drainage tube 3 is a single seamless long tube, insertion would be quite troublesome. To solve the above problems, the following design is made in this embodiment. Specifically, the drainage tube 3 includes a first tube 31 and a second tube 32. One end of the first tube 31 drains the body fluids in the patient's body and can be connected to a drainage tube placed in the body cavity during surgery. The middle part of the first tube 31 passes through the first opening 52, the collection chamber 51, and the second opening 53. One end of the second tube 32 is inserted into the interior of the container 2 and can be detachably connected to the drainage bag 8. The other end of the second tube 32 can be detachably connected to the first tube 31. The middle part of the second tube 32 passes through the second through hole 23.

[0071] With the above structural design, the first tube 31 and the second tube 32 can be installed separately and corresponding components can be inserted into them respectively. Since the length is relatively short compared to the whole tube, it is easy to disassemble and assemble. For example, when the exudate collection component 5 is installed after the first tube 31 is inserted into the patient's body, it is easier to disassemble and assemble the exudate collection component 5 more quickly. For example, the second tube 32 can easily pass through the second through hole 23 and enter the interior of the container 2 completely and quickly.

[0072] Referring to Figures 1, 11 and 12, the drained liquid flows along the extension direction of the drain pipe 3. In order to prevent the flow of liquid from being obstructed at the joint of adjacent components, the following design is made in this embodiment: Specifically, the diameter of the first pipe 31 is smaller than the diameter of the second pipe 32, and the diameter of the second pipe 32 is smaller than the diameter of the joint where the one-way valve 9 connects to the second pipe 32.

[0073] With the design of the above structure, the flow aperture increases when the liquid flows from one component to another adjacent component, so that the flow of the liquid is not obstructed and the next adjacent component is not pushed out, resulting in a more secure connection.

[0074] It should be noted that this application does not limit the detachable connection method between the first pipe 31 and the second pipe 32, or between the second pipe 32 and the one-way valve 9. It can be flexibly selected according to actual needs, such as the plug-in connection commonly used in actual operation, that is, the outer diameter of one pipe is slightly larger than the inner diameter of another pipe, and the interference fit is achieved by plugging and pulling, and the connection and sealing are achieved by deformation.
