Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a closed thoracic drainage bottle that is anti-tipping and capable of cumulative measurement. Background Technology

[0002] In thoracic surgery clinical practice, closed thoracic drainage bottles are core medical consumables for performing closed thoracic drainage. They are primarily used to drain effusion and pneumothorax from the patient's pleural cavity, restoring negative pressure to promote lung re-expansion. Simultaneously, the water seal within the bottle prevents outside air from entering the pleural cavity, ensuring the safety of the drainage process. Clinically used closed thoracic drainage bottles typically have a transparent body with fixed graduations. During nursing care, it is necessary to regularly read the drainage volume and observe the fluctuation of the water column within the water seal tube to assess the patient's recovery. The accuracy of the drainage volume data directly affects the reliability of clinical diagnosis and treatment.

[0003] However, existing closed chest drainage bottles still have several significant shortcomings in actual clinical applications. Firstly, they lack an effective anti-tipping metering design. When the drainage bottle is accidentally tipped over or tilted, the drainage fluid inside is prone to shifting or even overflowing from the bottle opening or vent, rendering the original fluid level markings unreliable. Medical staff cannot accurately read the drainage volume before tipping and must either estimate the data or discard the original record and start measuring again, which increases the workload of nurses and also poses a risk of inaccurate drainage volume records and medical errors. Secondly, the method for calculating daily drainage volume is problematic. The process is cumbersome. Clinically, the common method is to use adhesive tape to mark the position of the fluid level and manually calculate the difference to obtain the daily increase in drainage volume. The tape is easy to fall off, the markings are easy to blur, and it cannot intuitively show the cumulative drainage volume of the day. The operation efficiency is low during shift handover. Thirdly, it is inconvenient to observe the water column fluctuation. The fluctuation amplitude of the water column in the water seal tube is generally small, and it is difficult to clearly identify it when the light is insufficient at night. In addition, the drainage bottle is often placed in a low place under the bed. Medical staff have to bend over to complete the observation. The operation is not ergonomic. Turning on the ward main light during night rounds can also easily disturb the patient's normal rest.

[0004] Therefore, how to develop a tilt-resistant, cumulatively measurable closed chest drainage bottle that can accurately retain total drainage volume data after tilting, easily achieve daily zeroing and accumulation of drainage volume, and improve the ease of observing water column fluctuations has become a technical problem that urgently needs to be solved by people in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a closed chest drainage bottle that is anti-tipping and capable of cumulative measurement. Even after tipping, it can accurately retain the total drainage volume data, conveniently realize the daily drainage volume zeroing and accumulation, and improve the ease of observation of water column fluctuations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a tilt-resistant, cumulatively metering closed thoracic drainage bottle, comprising a drainage bottle body, a luminous illumination component, an auxiliary observation component, and a reading component. The drainage bottle body includes a baffle, one-way valves, a first connecting pipe, a second connecting pipe, a connecting hose, and a water-stop clamp. The baffle is horizontally positioned within the internal cavity of the drainage bottle body, dividing the internal cavity into a main chamber and a secondary chamber. Multiple one-way valves are spaced apart at the bottom of the baffle to allow unidirectional flow of liquid from the main chamber to the secondary chamber. The first connecting pipe and the second connecting pipe... The drainage bottle body is arranged at the bottom of one side, and the first and second connecting pipes are respectively connected to the secondary chamber and the main chamber. The two ends of the connecting hose are respectively connected to the first and second connecting pipes. The water-stopping clamp is clamped on the connecting hose to realize the connection and closure of the connecting hose. The luminous illumination component is arranged on the side wall of the drainage bottle body corresponding to the main chamber. The auxiliary observation component is slidably connected to the side wall of the drainage bottle body corresponding to the main chamber on the other side. The reading component is arranged on the side of the drainage bottle body corresponding to the secondary chamber.

[0007] Preferably, the drainage bottle body further includes a bottle cap, a water seal tube, a suction tube interface, and a vent. The vent is located at the top of the drainage bottle body and is connected to the secondary chamber. A hydrophobic and breathable membrane is provided at the vent to prevent liquid in the secondary chamber from overflowing from the vent when tilted, while ensuring ventilation. The top of the main chamber has a bottle opening, and the bottle cap is threaded onto the bottle opening. The water seal tube is located in the main chamber, with one end extending outward through the bottle cap to connect with the liquid outlet end of the drainage tube. The suction tube interface is located on the bottle cap and is connected to the main chamber.

[0008] Preferably, the luminous illumination component is a sheet-like component made of a photoluminescent self-luminous material, which is pasted and fixed on the outer wall of the main chamber corresponding to the main chamber of the drainage bottle body, and is used to illuminate the liquid surface in the main chamber and the water seal tube when there is insufficient light.

[0009] Preferably, the auxiliary observation component includes a square protrusion, a first guide groove, a first slider, a first guide block, and a magnifying glass. Two square protrusions are vertically spaced apart on the front side of the corresponding main chamber of the drainage bottle body. A first guide groove is provided on the side of the two square protrusions that are far apart from each other. The two ends of the first slider are provided with first guide blocks that match the first guide grooves. The first slider is slidably connected to the square protrusion through the first guide blocks. The magnifying glass is embedded in the middle of the first slider and is used to magnify and observe the water column fluctuation of the water seal pipe in the main chamber.

[0010] Preferably, the bottom of the first guide groove is configured as a sealing structure to prevent the first guide block from coming out.

[0011] Preferably, the reading assembly includes a mounting groove, an annular measuring tape, rotating rollers, a second guide groove, a slider assembly, and a protective shell. The side wall of the drainage bottle body corresponding to the secondary chamber is thickened. The mounting groove is formed on the thickened side wall of the drainage bottle body. The two rotating rollers are rotatably connected to the upper and lower ends of the mounting groove, respectively. The annular measuring tape is fitted onto the two rotating rollers and rotates cyclically with the rotating rollers. The annular measuring tape is provided with drainage volume scale lines. The two second guide grooves are arranged side by side in the vertical direction on the front side of the drainage bottle body near the annular measuring tape. The slider assembly is slidably connected to the drainage bottle body through the second guide groove, and the slider assembly is fixedly connected to the tape of the annular measuring tape, driving the annular measuring tape to move synchronously. The protective shell is inserted into the side of the drainage bottle body where the mounting groove is formed, and the protective shell is spaced apart from the annular measuring tape.

[0012] Preferably, the slider assembly includes a second slider, a second guide block, a locking bolt, a side connecting block, and a pointer. Two second guide blocks are arranged side by side on the side of the second slider facing the drainage bottle body, and the second guide blocks match the second guide groove. The second slider is slidably connected to the side of the drainage bottle body through the second guide blocks. The locking bolt is threaded onto the second slider, and the drainage bottle body has a locking groove that matches the locking bolt. The end of the locking bolt is used to abut against the bottom of the locking groove to lock the position of the second slider. The pointer is fixedly connected to the side of the second slider near the annular measuring tape through the side connecting block, and the pointer is fixedly connected to the zero mark of the annular measuring tape.

[0013] Preferably, the protective shell is made of transparent material, and the protective shell is provided with plug-in posts at the four corners, and the corresponding position of the drainage bottle body is provided with plug-in holes that match the plug-in posts.

[0014] Preferably, the total drainage volume scale is printed on the side wall of the secondary chamber corresponding to the drainage bottle body, and the cross-sectional area of ​​the secondary chamber is smaller than that of the main chamber.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows: 1) This invention separates the main chamber and the secondary chamber by a baffle and forms a one-way communication structure with the bottom one-way valve. During normal drainage, the liquid levels on both sides are kept level based on the principle of communicating vessels, and the total drainage volume can be accurately read through the scale of the secondary chamber. When the drainage bottle is accidentally tilted, the one-way valve automatically closes to lock the liquid in the secondary chamber. With the help of the hydrophobic and breathable membrane at the vent, the liquid overflow is prevented. The total drainage volume data before tilting can be completely preserved. There is no need to estimate or discard the original record. After righting, the liquid levels on both sides can be quickly restored to balance through the bypass connecting hose, and subsequent measurement can be continued directly. This effectively reduces the risk of inaccurate drainage volume records, reduces nursing errors, and also reduces the workload of medical staff. 2) This invention features a sliding and adjustable reading component on the side of the auxiliary chamber. By using a slider to move the circular measuring tape synchronously, the pointer can be aligned with the zero mark to the current liquid level, thus achieving a zero setting for the daily drainage volume. Subsequently, medical staff can directly read the scale on the circular measuring tape to obtain the daily increase in drainage volume, replacing the traditional method of marking with adhesive tape and manually calculating the difference. This avoids measurement errors caused by tape falling off or marking becoming blurry, and simplifies the measurement operation process during shift handover, effectively improving the work efficiency of clinical nursing and the accuracy of daily drainage volume statistics. 3) This invention is equipped with an auxiliary observation component and a night light illumination component. The adjustable magnifying glass can magnify the fluctuation amplitude of the water column in the water seal tube, making it easier for medical staff to clearly identify the water column fluctuation and judge the patency and leakage of the drainage system, which meets the ergonomic requirements of clinical operation. The photoluminescent self-illuminating night light illumination component can provide illumination in low light environment. Night patrols can be completed without turning on the ward's main light to observe the liquid level and water column, reducing interference with patients' nighttime rest and improving the convenience and user experience of clinical operation.

Detailed Implementation

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1-7 As shown, a tilt-resistant, cumulatively metering closed chest drainage bottle includes a drainage bottle body 1, a luminous illumination component 2, an auxiliary observation component 3, and a reading component 4. The drainage bottle body 1 includes a baffle 14, a one-way valve 15, a first connecting pipe 17, a second connecting pipe 18, a connecting hose 19, and a water-stop clamp. The baffle 14 is horizontally arranged in the internal cavity of the drainage bottle body 1, dividing the internal cavity of the drainage bottle body 1 into two independent chambers: a main chamber and a secondary chamber. Multiple one-way valves 15 are spaced apart at the bottom of the baffle 14 to allow unidirectional flow of liquid from the main chamber to the secondary chamber. The first connecting pipe 17 and the second connecting pipe 18... 18 are arranged side by side at the bottom of one side of the drainage bottle body 1, and the first connecting pipe 17 and the second connecting pipe 18 are respectively connected to the secondary chamber and the main chamber. The two ends of the connecting hose 19 are respectively connected to the first connecting pipe 17 and the second connecting pipe 18. The water-stopping clamp is clamped on the connecting hose 19 to realize the connection and closure of the connecting hose 19. The luminous illumination component 2 is arranged on the side wall of the drainage bottle body 1 corresponding to the main chamber. The auxiliary observation component 3 is slidably connected to the side wall of the drainage bottle body 1 corresponding to the other side of the main chamber. The reading component 4 is arranged on one side of the drainage bottle body 1 corresponding to the secondary chamber.

[0021] Specifically, under normal drainage conditions, after the drainage fluid flows into the main chamber, it can flow to the secondary chamber through the one-way valve 15 at the bottom. Based on the principle of communicating vessels, the liquid levels on both sides remain level. Multiple one-way valves 15 are arranged at intervals so that even when the drainage bottle body 1 is tilted at different angles, at least one of them can still maintain one-way conduction function, ensuring the accuracy of the liquid level in the secondary chamber corresponding to the total drainage volume. At the same time, when the bottle is tilted, the one-way valve 15 can automatically close, locking the liquid in the secondary chamber to prevent backflow and loss. After righting, opening the stop clamp and connecting the hose 19 can rebalance the liquid levels in both chambers without affecting subsequent continuous measurement. There is no need to discard the original measurement data, which can reduce the risk of nursing errors.

[0022] Specifically, in this embodiment, the one-way valve 15 is a silicone duckbill valve with low opening pressure, arranged horizontally at intervals along the bottom of the baffle 14. Under normal drainage conditions, the slight pressure of the liquid in the main chamber can push open the valve disc, ensuring that the liquid flows smoothly to the secondary chamber without affecting the accuracy of the liquid level balance due to valve resistance. When the drainage bottle body 1 is tilted and the liquid shows a reverse flow trend, the hydraulic pressure will squeeze the valve disc to make it close quickly. The reverse blocking effect is stable and reliable. Moreover, the silicone material has good biocompatibility and the overall structure is simple, making it suitable for the large-scale production of disposable medical consumables.

[0023] Specifically, the drainage bottle body 1 also includes a bottle cap 11, a water seal tube 12, a suction tube interface 13, and a vent 16. The vent 16 is located at the top of the drainage bottle body 1 and is connected to the secondary chamber. A hydrophobic and breathable membrane is provided at the vent 16 to prevent liquid in the secondary chamber from overflowing from the vent 16 when tilted, while ensuring ventilation. The top of the main chamber has a bottle opening, and the bottle cap 11 is threaded onto the bottle opening. The water seal tube 12 is located in the main chamber, with one end of the water seal tube 12 extending outward after passing through the bottle cap 11 to connect with the liquid outlet end of the drainage tube. The suction tube interface 13 is located on the bottle cap 11 and is connected to the main chamber.

[0024] Specifically, the lower end of the water seal tube 12 is immersed below the liquid level in the main chamber, forming a stable water seal structure to prevent outside air from entering the patient's chest cavity and ensuring drainage safety; the suction tube interface 13 can be connected to a clinical negative pressure suction device to adapt to treatment scenarios requiring negative pressure drainage; the secondary chamber is connected to the atmosphere through the vent 16, which can ensure that the internal liquid level rises and falls freely with the drainage flow. The hydrophobic and breathable membrane can prevent liquid from seeping out from the top when the bottle is tilted, avoiding loss of drainage fluid and causing measurement distortion, while not blocking gas flow and not affecting the liquid level adjustment under normal drainage conditions.

[0025] Specifically, the luminous illumination component 2 is a sheet-like component made of a light-emitting self-luminous material, which is pasted and fixed on the outer wall of the main chamber corresponding to the main chamber of the drainage bottle body 1, and is used to illuminate the liquid surface in the main chamber and the water seal pipe 12 when there is insufficient light.

[0026] Specifically, the sheet-like component made of photoluminescent self-luminous material can store energy through ambient light or the flashlight of medical staff. It can continuously emit soft light without external power supply at night or in low light environments. Medical staff can observe the liquid level and water column status without turning on the main light in the ward when making rounds, which can reduce interference with patients' rest at night and improve the ease of operation.

[0027] Specifically, the auxiliary observation component 3 includes a square protrusion 31, a first guide groove 32, a first slider 33, a first guide block 34, and a magnifying glass 35. Two square protrusions 31 are vertically spaced on the front side of the corresponding main chamber of the drainage bottle body 1. The two square protrusions 31 are provided with a first guide groove 32 on the side away from each other. The first slider 33 is provided with a first guide block 34 at both ends that matches the first guide groove 32. The first slider 33 is slidably connected to the square protrusion 31 through the first guide block 34. The magnifying glass 35 is embedded in the middle of the first slider 33 and is used to magnify and observe the water column fluctuation of the water seal pipe 12 in the main chamber.

[0028] Specifically, during use, medical staff can slide the first slider 33 up and down along the first guide groove 32 according to the daily fluctuation range of the water column in the water seal tube 12, and adjust the magnifying glass 35 to the corresponding height of the water column fluctuation. The magnifying effect of the magnifying glass 35 amplifies the small fluctuation of the water column, and medical staff can clearly identify the fluctuation when standing or at a slightly distance, so as to determine whether the drainage system is unobstructed and whether there is an air leakage problem, which meets the ergonomic requirements of clinical operation.

[0029] Specifically, the bottom of the first guide groove 32 is set as a sealing structure to prevent the first guide block 34 from coming out.

[0030] Specifically, the sealing structure can limit the first guide block 34 downward, preventing the first slider 33 from sliding down the first guide groove 32 under its own gravity, thus ensuring the structural stability of the component during use.

[0031] Specifically, the reading assembly 4 includes a mounting groove 41, an annular measuring tape 42, rotating rollers 43, a second guide groove 44, a slider assembly 45, and a protective shell 46. The side wall of the drainage bottle body 1 corresponding to the secondary chamber is thickened. The mounting groove 41 is formed on the thickened side wall of the drainage bottle body 1. The two rotating rollers 43 are rotatably connected to the upper and lower ends of the mounting groove 41, respectively. The annular measuring tape 42 is fitted onto the two rotating rollers 43 and rotates cyclically with them. A drainage device is provided on the annular measuring tape 42. The volume measurement scale is marked. Two second guide grooves 44 are vertically arranged side by side on the front side of the drainage bottle body 1 near the annular measuring tape 42. The slider assembly 45 is slidably connected to the drainage bottle body 1 through the second guide grooves 44. The slider assembly 45 is fixedly connected to the tape of the annular measuring tape 42 and drives the annular measuring tape 42 to move synchronously. The protective shell 46 is inserted into the side of the drainage bottle body 1 where the mounting groove 41 is opened, and the protective shell 46 is spaced apart from the annular measuring tape 42.

[0032] Specifically, the circular measuring tape 42 is rotated cyclically by the support of two upper and lower rotating rollers 43. When the slider assembly 45 slides, it can drive the tape body of the circular measuring tape 42 to move synchronously, so that the relative position of the scale on the circular measuring tape 42 is adjusted synchronously with the position of the slider assembly 45. The thickened side wall can provide sufficient processing space for the mounting groove 41, while ensuring the structural strength of the bottle at the corresponding position. The protective shell 46 can isolate the scale surface of the circular measuring tape 42 from external dust and medicine contamination, maintain the scale clear and readable for a long time, and protect the pointer 455.

[0033] Specifically, the slider assembly 45 includes a second slider 451, a second guide block 452, a locking bolt 453, a side connecting block 454, and a pointer 455. The two second guide blocks 452 are arranged side by side on the side of the second slider 451 facing the drainage bottle body 1, and the second guide blocks 452 match the second guide groove 44. The second slider 451 is slidably connected to the side of the drainage bottle body 1 through the second guide blocks 452. The locking bolt 453 is threadedly connected to the second slider 451, and the drainage bottle body 1 has a locking groove 47 that matches the locking bolt 453. The end of the locking bolt 453 is used to abut against the bottom of the locking groove 47 to lock the position of the second slider 451. The pointer 455 is fixedly connected to the side of the second slider 451 near the annular measuring tape 42 through the side connecting block 454, and the pointer 455 is fixedly connected to the zero mark of the annular measuring tape 42.

[0034] Specifically, during the daily morning shift handover, medical staff can slide the second slider 451 to align the pointer 455 with the current fluid level in the secondary chamber. Then, tighten the locking bolt 453 so that its end is pressed against the locking groove 47 to fix the position. Since the pointer 455 is fixedly connected to the zero mark of the circular tape measure 42, the zero mark is now aligned with the starting fluid level of the day, completing the zeroing operation for the day's measurement. During subsequent drainage, as the fluid level in the secondary chamber continues to rise, medical staff can directly read the scale value on the circular tape measure 42 corresponding to the current fluid level, which is the newly added drainage volume for the day. There is no need to manually paste markings or manually calculate the difference, which can improve the efficiency of shift handover and the accuracy of daily drainage volume measurement.

[0035] Specifically, the protective shell 46 is made of transparent material, and plug-in posts are provided at the four corners of the protective shell 46. The corresponding positions of the drainage bottle body 1 are provided with plug-in holes that match the plug-in posts.

[0036] Specifically, the transparent protective shell 46 does not obstruct the scale markings on the circular measuring tape 42, and does not affect normal reading operation. The four corner plugs and plug holes cooperate to achieve detachable plug-in fixation, which is easy to operate during production and assembly and can improve assembly efficiency. At the same time, if the surface of the circular measuring tape 42 is dirty, the protective shell 46 can be quickly removed for cleaning, making maintenance simple.

[0037] Specifically, the total drainage volume scale is printed on the side wall of the secondary chamber corresponding to the drainage bottle body 1, and the cross-sectional area of ​​the secondary chamber is smaller than that of the main chamber.

[0038] Specifically, when the drainage bottle body 1 is accidentally tipped over, the liquid in the secondary chamber is locked by the one-way valve 15 to maintain the original height. Medical staff can directly read the scale to obtain the total drainage volume before tipping over without estimating the data, which can avoid the distortion of drainage volume records.

[0039] The process of using this invention is as follows: First, medical staff take out the drainage bottle body 1, check the integrity of each component and the overall sealing performance, confirm that the one-way valve 15 at the bottom of the baffle 14 opens and closes normally, and that the water stop clamp on the connecting hose 19 is kept closed. Then, the extended end of the water seal tube 12 is sealed and connected to the outlet end of the patient's chest drainage tube. According to clinical treatment needs, a negative pressure suction device can be connected to the suction tube interface 13. After completing the assembly of the drainage system, the drainage bottle body 1 is placed vertically in a safe position next to the bed. Secondly, during the drainage process, the effusion in the patient's pleural cavity flows into the main chamber through the water seal tube 12, and the liquid flows into the secondary chamber simultaneously through the one-way valve 15 at the bottom of the baffle 14. Based on the principle of communicating vessels, the liquid levels on both sides are always kept at the same level. Medical staff can directly read the total drainage volume scale printed on the side wall of the secondary chamber of the drainage bottle body 1 to obtain the cumulative total drainage volume data. At the same time, the vent 16 at the top of the secondary chamber works with the hydrophobic and breathable membrane to maintain the air pressure balance inside and outside the chamber, which not only ensures the free rise and fall of the liquid level, but also prevents the liquid from overflowing when shaking normally. Secondly, during the daily morning shift handover, medical staff slide the second slider 451 up and down along the second guide groove 44 to make the pointer 455 accurately align with the current liquid level in the secondary chamber. Then, they tighten the locking bolt 453 so that its end is pressed against the bottom of the locking groove 47, thus locking the position of the second slider 451. Since the pointer 455 is fixedly connected to the zero mark of the circular tape measure 42, the zeroing setting of the drainage volume measurement for the day is completed. Medical staff in subsequent shifts can directly read the scale value on the circular tape measure 42 corresponding to the current liquid level to quickly obtain the newly added drainage volume for the day without manually pasting marks or manually calculating the difference. Then, if the drainage bottle body 1 is accidentally tilted, the multiple one-way valves 15 at the bottom of the baffle 14 will automatically close under the reverse pressure of the liquid, locking the liquid in the secondary chamber to prevent it from flowing back into the main chamber. The hydrophobic and breathable membrane at the vent 16 will also prevent the liquid from overflowing from the top. Medical staff can directly read the total drainage volume scale on the side wall of the secondary chamber to obtain the accurate total drainage volume data before tilting. Then, the drainage bottle body 1 is straightened to a vertical position, and the water stop clamp on the connecting hose 19 is opened so that the main chamber and the secondary chamber form a two-way communication channel through the first connecting pipe 17, the second connecting pipe 18 and the connecting hose 19. After the liquid levels on both sides are automatically balanced based on the principle of communicating vessels, the water stop clamp is closed again. At this time, medical staff can slide the second slider 451 again to make the pointer 455 align with the current liquid level after balance and tighten the locking bolt 453 to complete the locking, reset the starting position of the measurement for the day, and the device can resume normal measurement state without discarding the original measurement data and starting the recording again. Finally, during routine assessments of the drainage system's patency, medical staff can slide the first slider 33 up and down along the first guide groove 32 to adjust the magnifying glass 35 to the corresponding height of the water column fluctuation in the water seal tube 12. Through the magnification effect of the magnifying glass 35, the fluctuation amplitude of the water column can be clearly identified, thereby determining whether the drainage system is unobstructed and whether there is any air leakage. During nighttime inspections, the night light illumination component 2 can illuminate the liquid level and water seal tube 12 inside the main chamber with soft light emitted by the photoluminescent self-luminous material. Medical staff can observe the liquid level and water column status without turning on the ward's main light, reducing interference with the patient's nighttime rest.
