Description

Technical Field

[0001] This application relates to the field of medical equipment technology, and in particular to an alarm device for drainage fluid from a water-sealed bottle. Background Technology

[0002] A water-seal bottle is a device used for closed chest drainage. It uses at least two tubes, with the end of one tube submerged below the liquid surface to prevent air backflow and thus prevent bacteria from entering the chest cavity. However, the liquid in the water-seal bottle can leak. When the liquid level in the water-seal bottle is lower than the lower end of the tube that needs to be submerged, the water seal isolation effect will be lost. If air flows back into the patient's chest cavity, it will cause great harm to the patient. However, it is also tiring for caregivers to keep an eye on the water-seal bottle located under the bed at all times. Summary of the Invention

[0003] The purpose of this application is to provide an alarm device that can monitor at all times whether the water seal bottle is draining normally.

[0004] To achieve the above objectives, this application provides a water-sealed bottle drainage fluid alarm device: including an electrical box, the main body of which is a packaged box, the packaged box being connected to two wires via a terminal block, each wire having a conductive electrode plate at its end, the electrical box and the conductive electrode plates being adapted to be installed outside the water-sealed bottle, the end of a conduit submerged below the liquid surface within the water-sealed functional cavity of the water-sealed bottle being located between the two conductive electrode plates, and a buzzer being provided on the packaged box, adapted to emit an alarm sound when the capacitance of the two conductive electrode plates changes significantly, promptly alerting caregivers or medical personnel that the water-sealed bottle may be malfunctioning.

[0005] As a preferred embodiment, the side of the packaging box has a mounting plate with insertion holes, and the outer side of the water seal bottle has at least two insertion posts suitable for insertion into the insertion holes, which can achieve quick assembly and disassembly, and facilitate configuration and replacement.

[0006] As a preferred embodiment, the outer surface of each of the plug-in pins also has a retaining ring, which is adapted to be interference-fitted with the plug-in hole to prevent the electrical box from slipping off the body of the drainage bottle and improve the configuration stability of the electrical box.

[0007] As a preferred embodiment, the outer side of the water-sealed bottle also has a retainer, the top surface of which has a downwardly extending slot, and the conductive electrode plate is adapted to be inserted into the slot to ensure the stability of the conductive electrode plate.

[0008] As a preferred embodiment, the outer side of the card holder is provided with a sliding groove that communicates with the slot. The sliding groove extends to the top surface of the card holder and is adapted to form a sliding pair with the wire to avoid interference with the wire when the conductive electrode plate is inserted.

[0009] As a preferred embodiment, the packaging box is also provided with a flashing light. The buzzer, flashing light, and wires are all electrically connected to the circuit board inside the packaging box for power supply and signal transmission.

[0010] As a preferred embodiment, the water-sealed bottle body is a three-cavity bottle body, which has a liquid collection cavity, a water seal cavity, and a pressure regulating cavity. A conduit assembly is provided at the top of the three-cavity bottle body. The conduit assembly includes a first straight tube, a first bridging tube, a second bridging tube, a second straight tube, and a pressure regulating tube. The lower end of the first straight tube is inserted into the liquid collection cavity; one end of the first bridging tube is inserted into the liquid collection cavity above the liquid surface, and the other end is inserted into the water seal cavity below the liquid surface, located between the two conductive electrode plates; one end of the second bridging tube is inserted into the water seal cavity above the liquid surface, and the other end is inserted into the pressure regulating cavity above the liquid surface; the lower end of the second straight tube is inserted into the pressure regulating cavity above the liquid surface; and the lower end of the pressure regulating tube is inserted into the pressure regulating cavity below the liquid surface. By changing the depth of the lower end of the pressure regulating tube below the liquid surface, the maximum suction force generated by the first straight tube is adjusted.

[0011] As a preferred embodiment, the three-chamber bottle has a first and a second tube hole at the top of the collection chamber. The first tube hole allows the first straight tube to pass through, and the upper end of the first straight tube is connected to the patient. The second tube hole allows the end of the first bridging tube to pass through. The three-chamber bottle has a third and a fourth tube hole at the top of the water seal chamber. The third tube hole allows the end of the first bridging tube to pass through, and the fourth tube hole allows the end of the second bridging tube to pass through. The three-chamber bottle has a fifth, a sixth, and a seventh tube hole at the top of the pressure regulating chamber. The fifth tube hole allows the end of the second bridging tube to pass through, the sixth tube hole allows the second straight tube to pass through, and the end of the second straight tube outside the pressure regulating chamber is connected to the suction machine. The seventh tube hole allows the pressure regulating tube to pass through, and the upper end of the pressure regulating tube is connected to the atmosphere to ensure the stability of the negative pressure inside the pressure regulating chamber.

[0012] As a preferred embodiment, the inner walls of the first, second, third, fourth, fifth, sixth, and seventh pipe holes are all provided with sealing rings, and the first straight pipe, first bridge pipe, second bridge pipe, second straight pipe, and pressure regulating pipe are all made of glass, which has good transparency and hardness, making it convenient for observation and insertion.

[0013] As a preferred option, the three-chamber bottle is made of transparent material to facilitate observation of the liquid level in each chamber.

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

[0015] (1) By designing a capacitive monitoring component, it can sense whether the end of the catheter is properly submerged below the liquid surface without contacting the liquid inside the water seal bottle. It does not require caregivers to watch for a long time, and can also quickly trigger an alarm when there is abnormal drainage in the water seal bottle, prompting medical staff to handle the situation quickly. This effectively reduces the harm to patients caused by leakage of liquid inside the water seal bottle.

[0016] (2) By designing plug-in posts and card slots on the outside of the water seal bottle to constrain the electrical box and conductive electrode plate, the installation is not only stable, but also convenient for disassembly and assembly. The configuration and replacement of the water seal bottle drainage liquid alarm device are more convenient. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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. They should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figure 1-8The water seal bottle drainage fluid alarm device shown includes an electrical box 3, which contains electrical components both inside and outside. The main body of the electrical box 3 is a package 301, which encapsulates a power supply and a circuit board. The circuit board has a processor. The package 301 is connected to two wires 4 via a terminal block 302. Each wire 4 is connected to a conductive electrode plate 5 at its end. The two conductive electrode plates 5 are parallel to each other to form a capacitor structure. The electrical box 3 and the conductive electrode plates 5 need to be installed outside the water seal bottle. The side of the package 301 has a safety feature. Mounting plate 303, usually two, symmetrical about the encapsulation box 301. Each mounting plate 303 has a plug hole 304. The outer side of the water seal bottle has at least two plug posts 211, which fit into the plug hole 304. The outer surface of each plug post 211 also has a coaxial and larger retaining ring 212, which is used to interfere with the plug hole 304 to prevent the plug post 211 from disengaging from the plug hole 304 of the mounting plate 303, thereby ensuring the installation stability of the electrical box 3 outside the water seal bottle.

[0031] The outer side of the water-sealed bottle also has a card holder 213. There are two card holders 213, located on the opposite outer side of the water-sealed bottle. The top surface of each card holder 213 has a slot 214 extending downward. The conductive electrode plate 5 will be inserted into the slot 214 in a vertical direction. The outer side of each card holder 213 also has a sliding groove 215 that connects to the slot 214. The sliding groove 215 extends to the top surface of the card holder 213 and can form a sliding pair with the wire 4, allowing the wire 4 connected to the conductive electrode plate 5 to slide through.

[0032] The end of the conduit submerged below the liquid surface in the water-sealing chamber of the water-sealed bottle is located between two conductive electrode plates 5. The capacitance between the two conductive electrode plates 5 differs significantly depending on whether there is liquid or not. A buzzer 305 is installed on the encapsulation box 301, which can sound an alarm when the capacitance of the two conductive electrode plates 5 changes significantly. A flashing light 306 is also installed on the encapsulation box 301, which works synchronously with the buzzer 305, flashing to remind medical personnel of the location of the water-sealed bottle. The buzzer 305, the flashing light 306, and the wire 4 are all electrically connected to the circuit board inside the encapsulation box 301. The wire 4 transmits the capacitance of the conductive electrode plates 5 to the circuit board, and the processor on the circuit board judges whether the capacitance data is abnormal. If abnormal, the processor will supply power to the buzzer 305 and the flashing light 306, causing them to sound an alarm.

[0033] Typically, the water seal bottle body is a three-chamber bottle body 2, made of transparent material, usually plastic, such as the commonly used polyvinyl chloride (PVC). The three-chamber bottle body 2 contains a liquid collection chamber 201, a water seal chamber 202, and a pressure regulating chamber 203. The three chambers are isolated from each other by partitions inside the three-chamber bottle body 2. A conduit assembly 1 is installed at the top of the three-chamber bottle body 2. The conduit assembly 1 includes a first straight pipe 101, a first bridge pipe 102, a second bridge pipe 103, a second straight pipe 104, and a pressure regulating pipe 105. These conduits are all made of glass, usually plexiglass, which has good light transmittance and is not easily broken, thus avoiding sharpness and danger. The lower end of the first straight pipe 101 is inserted into the liquid collection chamber 201, generally below the liquid surface. When the liquid accumulation in the liquid collection chamber 201 is relatively high and about to reach its upper limit, the lower end of the first straight pipe 101... The first bridge pipe 102 is inserted into the liquid collecting chamber 201, above the liquid surface, and the other end of the first bridge pipe 102 is inserted into the water seal chamber 202, below the liquid surface, and located between the two conductive electrode plates 5. The second bridge pipe 103 is inserted into the water seal chamber 202, above the liquid surface, and the other end of the second bridge pipe 103 is inserted into the pressure regulating chamber 203, above the liquid surface. The lower end of the second straight pipe 104 is inserted into the pressure regulating chamber 203, above the liquid surface. The lower end of the pressure regulating pipe 105 is inserted into the pressure regulating chamber 203, below the liquid surface. It should be noted that the liquid level in the pressure regulating chamber 203 should be higher than the liquid level in the water seal chamber 202. By changing the depth of the lower end of the pressure regulating pipe 105 below the liquid surface in the pressure regulating chamber 203, the upper limit of the suction force of the first straight pipe 101 can be changed.

[0034] The three-chamber bottle 2 has a first tube hole 204 and a second tube hole 205 at the top of the collection chamber 201. The first tube hole 204 allows the first straight tube 101 to pass through, and the upper end of the first straight tube 101 is connected to the patient via a medical tubing. The second tube hole 205 allows the end of the first bridge tube 102 to pass through. The three-chamber bottle 2 has a third tube hole 206 and a fourth tube hole 207 at the top of the water seal chamber 202. The third tube hole 206 allows the end of the first bridge tube 102 to pass through, and the fourth tube hole 207 allows the end of the second bridge tube 103 to pass through. The three-chamber bottle 2 has a fifth tube hole 208, a sixth tube hole 209, and a seventh tube hole 210 at the top of the pressure regulating chamber 203. The fifth tube hole 208 allows the end of the second bridge tube 103 to pass through, and the sixth tube hole 209 allows the second straight tube 104 to pass through. 04 is located outside the pressure regulating chamber 203 and is connected to the suction machine, so that negative pressure is generated in the three chambers of the three-chamber bottle 2, thereby generating suction for drainage. The seventh tube hole 210 is for the pressure regulating tube 105 to pass through. The upper end of the pressure regulating tube 105 is connected to the atmosphere. When the air inside the pressure regulating chamber 203 is sucked out too quickly, the outside air will enter the pressure regulating chamber 203 faster through the pressure regulating tube 105, thereby maintaining the negative pressure inside the pressure regulating chamber 203. The inner walls of the first tube hole 204, the second tube hole 205, the third tube hole 206, the fourth tube hole 207, the fifth tube hole 208, the sixth tube hole 209 and the seventh tube hole 210 are all provided with sealing rings to tightly wrap the outside of the tubes, preventing outside air from entering the three-chamber bottle 2 from the gap between the inner wall of the tube hole and the outer side of the tube.

[0035] Working principle: When in use, first inject physiological saline into the water seal chamber 202 and the pressure regulating chamber 203 through the tube hole, so that the liquid level in the pressure regulating chamber 203 is higher than the liquid level in the water seal chamber 202. Then, insert all the catheters into the corresponding tube holes, connect the upper end of the first straight tube 101 to the part of the patient that needs drainage through the medical tubing, connect the second straight tube 104 to the input end of the suction device, start the suction device, and adjust the pressure regulating inner tube to the depth below the liquid level in the pressure regulating chamber 203 until the suction generated by the first straight tube 101 is appropriate.

[0036] Then, the electrical box 3 is inserted into the plug 211 on the outside of the three-chamber bottle 2. The two conductive electrode plates 5 are then inserted into the card holder 213. The insertion depth of the first bridge pipe 102 is then finely adjusted so that one end of the first bridge pipe 102 in the water seal cavity 202 is positioned between the two conductive electrode plates 5 and remains below the liquid level in the water seal cavity 202. Since the sensor component of this alarm device utilizes the principle of capacitor charging and discharging, the conductive electrode plates 5 need to be kept away from metal parts, such as metal bed legs. The water seal bottle with the alarm device configured is generally placed directly under the hospital bed. This distance is sufficient to reduce the influence of the metal bed legs on the conductive electrode plates 5 to a negligible level. Finally, the electrical box 3 is activated, and the contents of the sealing box 301 are activated. The circuit board first connects to the charging circuit to charge the conductive electrode plate 5 to the set voltage. Then, the circuit board switches to the discharge circuit to allow the conductive electrode plate 5 to discharge spontaneously. The discharge curve of the conductive electrode plate 5 is recorded by the processor on the circuit board. Since the capacitance between the two conductive electrode plates 5 is different in the presence and absence of liquid, whether there is water near the end of the first bridge pipe 102 that needs to be sealed corresponds to different discharge curves of the conductive electrode plate 5. When the processor determines that the discharge curve of the conductive electrode plate 5 corresponds to the absence of water, it will send a working instruction to the buzzer 305 and the flashing light 306 so that the caregiver can hear or see the alarm and quickly notify the medical staff to handle the situation and prevent the harm to the patient caused by the abnormal operation of the water seal bottle.

Those skilled in the art should understand that this application is not limited to the above embodiments.
