Description

Technical Field

[0001] This invention relates to the field of chest drainage technology, and more specifically, to a multi-chamber chest drainage bottle. Background Technology

[0002] A chest drainage bottle is a sterile, closed drainage system whose main function is to drain abnormally accumulated air, blood, pus, or other fluids from the patient's chest cavity, while preventing these substances or outside air from flowing back into the chest cavity. This helps the lung tissue re-expand and restore normal respiratory function. Its structure includes a water-seal bottle, drainage tube, and negative pressure regulating device. The water seal principle prevents gas or fluid backflow and helps the lung tissue re-expand.

[0003] The water-seal bottle is the core of the chest drainage system, with the end of the drainage tube submerged in water. This forms a one-way valve, allowing only gas and fluid from the chest cavity to flow out while preventing outside air from entering. However, when the bottle is tilted, the water in the water-seal cavity flows, causing the end of the drainage tube to either fail to maintain the required depth below the fluid level or become exposed to air. This situation allows atmospheric pressure to directly invade the patient's chest cavity, disrupting the physiological negative pressure environment established to promote lung re-expansion.

[0004] Therefore, preventing chest drainage bottles from tipping over is of paramount importance. Current methods for preventing tipping typically involve adding a crossbar to the side. While this ideally improves stability, it proves insufficient against complex external forces encountered in clinical settings (such as accidental kicks or pulling of tubing), revealing safety hazards stemming from a lack of redundant design. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-chamber thoracic drainage bottle, which achieves redundant design by limiting the tilted bottle body and compensating for a predetermined amount of fluid in the corresponding chamber, thereby solving the problem mentioned in the background art, namely, that a single lateral support is insufficient under complex external forces in clinical practice.

[0006] To achieve the above objectives, a multi-chamber thoracic drainage bottle includes a bottle body fixedly mounted on a base. The bottle body has a metering chamber and a water seal chamber inside. A support arm is provided on the side wall of the bottle body to limit the tilted bottle body to a predetermined angle. A fluid replenishment box is provided on the bottle body corresponding to the water seal chamber. The fluid replenishment box corresponding to the water seal chamber stores the amount of compensating fluid required to maintain the function of the corresponding chamber at the predetermined angle.

[0007] The replenishment box is equipped with a gravity valve, which controls the liquid in the replenishment box to flow into the corresponding chamber when the bottle is at a predetermined angle.

[0008] In the above technical solution, the support arm includes limiting plates symmetrically arranged on both sides of the base, and a support plate is provided at the end of the limiting plate; the angle between the support plate and the top surface of the limiting plate is greater than 90 degrees. Under normal conditions, the limiting plates restrict the tilt of the bottle. When the bottle is still tilted, the tilted support plate further restricts the tilted bottle. After restriction, the liquid volume is compensated by the replenishment box, thereby preventing the phenomenon that the end of the drainage tube cannot be maintained at the required depth below the liquid surface or is exposed to air.

[0009] In addition, a pressure regulating chamber is provided inside the bottle, and a replenishment box is provided at the part of the bottle corresponding to the pressure regulating chamber. The replenishment box corresponding to the pressure regulating chamber stores the amount of compensation liquid required for the corresponding chamber to maintain its function at a predetermined angle.

[0010] Based on this, the bottom of the liquid replenishment box is provided with a guide section, and the side of the guide section away from the base is inclined. When the bottle is at a predetermined angle, the inclined surface of the guide section tilts upward; the side wall of the bottle is provided with a through hole communicating with the bottom of the guide section.

[0011] Based on this, the gravity valve includes a baffle fixedly installed inside the replenishment box, and the top of the baffle is provided with a through opening;

[0012] It also includes a valve plate, one end of which slides through the side wall of the refill box, and the other end is fixedly connected to a counterweight. When the bottle is tilted, the counterweight causes the valve plate to disengage from the inlet, thus opening the inlet.

[0013] In addition, the bottom of the water seal chamber and the pressure regulating chamber are provided with drain ports to discharge the compensation liquid when tilted.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In this multi-chamber thoracic drainage bottle, the required fluid for the water seal chamber and pressure regulating chamber is pre-stored in the refill box, and a support plate is provided for secondary protection of the bottle body. The support plate restricts the tilted bottle body to a predetermined angle to prevent the bottle body from tilting further. Subsequently, at the predetermined angle, the fluid in the refill box enters the water seal chamber and pressure regulating chamber, thereby maintaining the fluid required for the normal operation of the water seal chamber and pressure regulating chamber, so as to maintain the continuity of system function and provide additional time for righting the bottle body.

[0028] The technical solutions in 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.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Example

[0031] To address the issue that simple lateral support is insufficient in the face of complex external forces in clinical settings (such as accidental kicks or traction on tubes), this invention provides a multi-chamber thoracic drainage bottle. For example... Figure 1 As shown, the chest drainage bottle includes a bottle body 110 fixedly mounted on a base 100. The bottle body 110 has multiple chambers inside, namely a metering chamber 111, a water seal chamber 112, and a pressure regulating chamber 113.

[0032] like Figure 1 and Figure 2 As shown, the metering chamber 111 is located on the far left of the bottle body 110. Two partitions 117 extend upwards from its bottom, with a gap between the top of each partition 117 and the top of the metering chamber 111, dividing the interior of the metering chamber 111 into three interconnected metering chambers. Furthermore, a drainage port is connected to the top of the leftmost metering chamber of the metering chamber 111. This drainage port is connected to a chest drainage tube, through which gas (refer to...) in the pleural cavity is drained. Figure 2 (white arrow in the middle) and liquid (reference) Figure 2 (The black arrow in the middle) guides the fluid into the metering chamber 111. The drainage fluid first accumulates in the leftmost metering chamber of the metering chamber 111. When the level of the drainage fluid is higher than the height of the left partition 117, the drainage fluid flows into the next metering chamber. In this embodiment, the bottle body 110 is provided with graduation lines corresponding to each metering chamber. The volumes recorded on the graduations are stacked sequentially, and the liquid flow rate can be quickly understood through the graduation lines.

[0033] Gas in the metering chamber 111 flows into the water seal chamber 112. Specifically, the water seal chamber 112 is located to the right of the metering chamber 111 and is connected to it via a drainage pipe 115. One end of the drainage pipe 115 is connected to the top of the metering chamber 111, and the other end is connected to the bottom of the water seal chamber 112. Physiological saline solution is placed at the bottom of the water seal chamber 112, with the saline solution level higher than the section where the drainage pipe 115 connects to the water seal chamber 112, thus acting as a water seal. To expel the gas, air is evacuated from the water seal chamber 112 through the evacuation port 116 at the top. At this point, the pressure inside the water seal chamber 112 is lower than the pressure inside the drainage pipe 115. Under this pressure difference, the gas in the drainage pipe 115 passes through the water layer in the form of bubbles and is finally discharged from the evacuation port 116.

[0034] In addition, the pressure regulating chamber 113 regulates the pressure within the water seal chamber 112. The pressure regulating chamber 113 is located on the right side of the water seal chamber 112. Its top is connected to the top of the water seal chamber 112, and its right side is connected to the water injection chamber 114. Water is injected into the pressure regulating chamber 113 through the water injection chamber 114. When the negative pressure within the water seal chamber 112 is high, external gas is drawn into the water injection chamber 114, then passes through the water layer in the pressure regulating chamber 113, and finally enters the water seal chamber 112. This design prevents excessive negative pressure within the water seal chamber 112 from affecting the patient.

[0035] It should be noted that the metering chamber 111, water seal chamber 112 and pressure regulating chamber 113 are all existing technologies, and their connection relationships and corresponding pipeline interfaces can be referred to existing technologies.

[0036] The above process works normally when the bottle 110 is in a vertical position, but when the bottle 110 is tilted, such as... Figure 10As shown, when tilted, a portion of the drain tube 115 connected to the water seal cavity 112 is exposed to air. This operation allows the gas in the metering cavity 111 to be extracted without a large negative pressure within the water seal cavity 112. To avoid this phenomenon, the present invention provides a replenishment box 130 at the locations of the bottle body 110 corresponding to the water seal cavity 112 and the pressure regulating cavity 113, with a filling port at the top of the replenishment box 130. Furthermore, a support arm is provided on the side wall of the bottle body 110. The support arm is used to limit the tilted bottle body 110 to a predetermined angle. The replenishment box 130 corresponding to the water seal cavity 112 and the pressure regulating cavity 113 stores the amount of compensating liquid required to maintain the function of the corresponding cavity at the predetermined angle. In addition, a gravity valve is provided in the replenishment box 130, which controls the liquid in the replenishment box 130 to flow into the corresponding cavity when the bottle body 110 is at the predetermined angle. With this design, after the water seal chamber 112 and the pressure regulating chamber 113 are tilted, the liquid replenishment box 130 can compensate for the liquid, thereby maintaining the liquid required for the normal operation of the water seal chamber 112 and the pressure regulating chamber 113, so as to maintain the continuity of system function.

[0037] It should be noted that the present invention may also omit the pressure regulating chamber 113. In this case, the liquid replenishment box 130 corresponds only to the water seal chamber 112 and is used to compensate the liquid in the water seal chamber 112.

[0038] In the above description, the support arm includes limiting plates 121 symmetrically arranged on both sides of the base 100, and a support plate 122 is provided at the end of the limiting plate 121. In this embodiment, the structure of the limiting plate 121 is the same as the current anti-tipping structure, that is, the limiting plate 121 widens the bottom width of the base 100 by its own length, thereby reducing the probability of the base 100 tipping over. The redundancy design is mainly reflected in the support plate 122, which is fixedly connected to the limiting plate 121, for example, by integral molding. The support plate 122 is tilted upwards, specifically at an angle greater than 90 degrees with the top surface of the limiting plate 121. At this time, when the base 100 tilts, the side of the support plate 122 contacts the ground, thereby limiting the tilted bottle 110 and preventing the bottle 110 from tilting further. Furthermore, the height of the top of the support plate 122 is preferably higher than the height of the middle part of the bottle 110, and the longer length can increase the probability of successfully limiting the base 100.

[0039] Furthermore, in addition to the fixed connection between the support plate 122 and the limiting plate 121, the present invention provides another embodiment, such as... Figures 7-9As shown, a telescopic plate 124 is rotatably connected to one end of the limiting plate 121. Specifically, a shaft 123 is provided at one end of the limiting plate 121, and the end of the telescopic plate 124 is sleeved on the outer ring of the shaft 123. There is friction between the telescopic plate 124 and the shaft 123, for example, an interference fit between the shaft 123 and the telescopic plate 124. The large friction generated by the interference fit can prevent the base 100 from pressing the telescopic plate 124 to rotate when tilted. Alternatively, a locking structure, such as a bolt, can be provided at the connection between the telescopic plate 124 and the shaft 123 to restrict the rotation of the telescopic plate 124. The advantages of this embodiment are as follows... Figure 9 As shown, in some environments, the telescopic plate 124 can be controlled to retract, and then the telescopic plate 124 can be rotated to the limiting plate 121 to reduce space occupation.

[0040] After the support plate 122 restricts the tilt of the bottle 110, the replenishment box 130 is also tilted. To ensure that the liquid can flow into the water seal chamber 112 or the pressure regulating chamber 113 through the replenishment box 130 after tilting, such as... Figures 3-6 As shown, in this embodiment, the bottom of the replenishment box 130 is configured as a guide portion 131. The side of the guide portion 131 away from the base 100 is designed with an inclination, giving the guide portion 131 an overall structure that is wider at the top and narrower at the bottom. Furthermore, when the support plate 122 limits the bottle body 110 to a predetermined angle, the inclined surface of the guide portion 131 remains in an upward inclination, allowing the liquid in the replenishment box 130 to flow along the slope of the guide portion 131. Next, the side wall of the bottle body 110 is provided with a through hole 132 communicating with the bottom of the guide portion 131. The liquid in the replenishment box 130 can flow into the corresponding chamber through the through hole 132.

[0041] The gravity valve includes a baffle 141 fixedly installed inside the replenishment box 130. The baffle 141 divides the interior of the replenishment box 130 into upper and lower parts. The space above the baffle 141 is used to store the amount of compensation fluid required to maintain the function of the corresponding chamber at a predetermined angle. A through-hole 142 is provided at the top of the baffle 141. A slot is provided on the side of the baffle 141 away from the bottle body 110. A valve plate 143 is slidably installed in the slot. When the valve plate 143 enters the slot, it blocks the through-hole 142, preventing the liquid above the baffle 141 from flowing out through the through-hole 142. One end of the valve plate 143 slides through the side wall of the replenishment box 130 and is fixedly connected to a counterweight 144. When the bottle body 110 is tilted, the counterweight 144 can drive the valve plate 143 out of the slot, opening the through-hole 142.

[0042] The working principle of this invention will be described in detail below:

[0043] Taking the water seal cavity 112 as an example, when the bottle body 110 is tilted, the side wall of the support plate 122 contacts the ground. At this time, the counterweight 144 located in the tilting direction moves along... Figure 6The movement of the solid black arrow in the image causes the valve plate 143 to disengage from the slot. At this time, the liquid at the top of the baffle 141 flows into the guide portion 131 through the through-hole 142. Guided by the inclined surface of the guide portion 131, the liquid enters the water seal cavity 112 through the through-hole 132, compensating for the liquid in the water seal cavity 112 and thus preventing... Figure 10 The phenomenon occurs.

[0044] It is worth noting that drain ports can also be provided at the bottom of the water seal chamber 112 and the pressure regulating chamber 113. In this way, when the tilted bottle 110 is straightened, the drain ports can be opened to discharge the compensating liquid that caused the tilt.

[0045] In summary, the present invention uses a replenishment box 130 to pre-store the required liquid for the water seal chamber 112 and the pressure regulating chamber 113, and a support plate 122 to provide secondary protection for the bottle 110. The support plate 122 restricts the tilted bottle 110 to a predetermined angle, preventing the bottle 110 from tilting further. Subsequently, at the predetermined angle, the liquid in the replenishment box 130 enters the water seal chamber 112 and the pressure regulating chamber 113, thereby maintaining the liquid required for the normal operation of the water seal chamber 112 and the pressure regulating chamber 113, maintaining the continuity of system function, and providing additional time for righting the bottle 110.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
