detailed description

The specific embodiments of the present invention are further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

FIG. 1 shows a schematic structural view of a multifunctional drainage bottle 10 according to an exemplary embodiment of the present application. As shown in FIG. 1, the multi-functional drainage bottle 10 can include a main body 1 and a monitoring device 2, the main body 1 can be used to collect drainage liquid, and the monitoring device 2 can be installed outside the main body 1 to monitor the inside of the main body 1 in a contactless manner. The liquid level of the drainage liquid, that is, the monitoring device 2 does not contact the drainage liquid. Through the non-contact flow monitoring device, many beneficial technical effects can be realized, for example, the sterilization and anti-leakage treatment of the monitoring device can be avoided, thereby effectively reducing the manufacturing difficulty of the drainage bottle, and the entire monitoring device 2 is located outside the main body 1. The drainage bottle can be removed after use, thereby achieving rapid recycling, further reducing the production cost of the drainage bottle, and making the drainage bottle acceptable to the market, thereby entering the practical application in the medical field. Examples of the monitoring device 2 usable in the present invention include a capacitance level gauge, an ultrasonic level gauge, a radar level gauge, etc., and Fig. 1 shows a capacitance level gauge 2.

As shown in FIG. 1, the main body 1 may include a drainage chamber 11 and a liquid sealing chamber 12, which may be disposed adjacent to each other, and the bottoms of the two are separated by a partition 13 which communicates with each other through the aperture 14. The liquid sealing chamber 12 may be provided with a sealing liquid and an air guiding tube 15, and in some embodiments, the sealing liquid may be water or other washing liquid. The top of the air guiding tube 15 is connected to the one-way valve 16, and the one-way valve 16 is disposed in the aperture 14, so that the drainage chamber 11 can be unidirectionally communicated through the one-way valve 16 in the aperture 14 and the air guiding tube connected to the one-way valve 16 Liquid sealing chamber 12. The guide tube 15 can extend downwardly to the bottom of the liquid seal chamber 12 so as to extend below the liquid level of the seal liquid. The drainage liquid enters into the drainage chamber 11 from the drainage inlet located at the top of the drainage chamber 11, and the introduced gas passes through the aperture 14 and enters the sealing liquid through the guiding tube 15, and a part of the gas can be absorbed by the sealing liquid, and the remaining gas can pass through The outlet at the top of the liquid seal chamber 12 is discharged. By providing the check valve 16 in the communication passage between the drain chamber 11 and the liquid seal chamber 12, it is possible to prevent backflow. When the drainage bottle 10 is normally placed upright, the one-way valve 16 is opened, and the gas in the drainage chamber 11 can enter the liquid sealing chamber 12 via the one-way valve 16; when the drainage bottle 10 is dumped, the one-way valve 16 is closed, thereby being able to The sealing liquid in the drainage chamber 11 is prevented from entering the liquid sealing chamber 12 or the sealing liquid in the liquid sealing chamber 12 is introduced into the drainage chamber 11. A scale line may be disposed on the side walls of the drainage chamber 11 and the liquid sealing chamber 12 to facilitate observation of the liquid level of the drainage liquid and the sealing liquid.

The capacitance level gauge 2 may include at least one capacitance probe that may be directly adhered to the side outer surface of the body 1. Fig. 1 shows four

capacitive probes

2a, 2b, 2c and 2d which are arranged at different heights of the lateral outer surfaces of the body 1 and are evenly spaced apart. It should be understood that the capacitance level gauge 2 can include a greater number of capacitive probes.

The liquid level monitoring principle of the capacitance level gauge 2 is briefly described below. When there is no drainage fluid close to the capacitive sensing probe, there is a certain static capacitance to the ground due to the presence of distributed capacitance on the sensing probe. As the liquid level gradually rises closer to the sensing probe, the parasitic capacitance of the drain fluid is coupled to the static capacitor, causing the final capacitance of the inductive probe to become larger. Therefore, liquid level monitoring can be achieved by sensing the change in the capacitance value of the probe to determine whether the liquid level has reached the height at which the sensing probe is located.

It can be understood that a single sensing probe can only determine whether the liquid level has reached the height of the sensing probe, but when the liquid level has not reached the position or has exceeded the position, the specific height of the single sensing probe to the liquid level is one. Nothing to know. Thus, in some embodiments of the invention, multiple sensing probes can be placed at different heights to determine the height interval in which the liquid level is located. For example, in the embodiment of FIG. 1, it can be determined that the liquid level has not reached the height corresponding to the probe 2a, reached the height corresponding to the probe 2a but has not reached the height corresponding to the probe 2b, and reached the height corresponding to the probe 2b but has not yet reached The height corresponding to the probe 2c reaches the height corresponding to the probe 2c but has not reached the height corresponding to the probe 2d or reaches the height corresponding to the probe 2d. The denser the inductive probe is placed along the height, the more accurate the level height monitoring. The number of sensing probes or their density can be set according to the actual needs.

2A and 2B are schematic structural views of a multifunctional drainage bottle according to other exemplary embodiments of the present application. The multifunctional drainage bottle of Figures 2A and 2B is substantially identical to Figure 1, except that the monitoring device 2 comprises an ultrasonic level gauge, wherein the ultrasonic level gauge 2 is disposed on the top surface of the body 1 in Figure 2A, in Figure 2B The middle ultrasonic level gauge 2 is disposed on the bottom surface of the main body 1.

The ultrasonic level gauge 2 can transmit ultrasonic waves toward the drainage liquid, and receive an echo signal reflected by the liquid level of the drainage liquid, according to the time difference between the transmission time and the echo reception time, and the propagation speed of the ultrasonic wave in the corresponding medium, that is, The stroke of the ultrasonic wave can be calculated to determine the liquid level of the drainage liquid. In the example of Figure 2A, the ultrasound propagates primarily in air, and in the example of Figure 2B, the ultrasound propagates primarily in the drainage fluid. It will be appreciated that the example of Figure 2B can directly determine the level of the drainage fluid, while the example of Figure 2A requires subtracting half of the height of the drainage lumen 11 of the drainage vial 10 from the ultrasonic stroke to obtain the level of the drainage fluid.

The ultrasonic level gauge 2 may be directly adhered to the top or bottom surface of the main body 1, or may be attached to the top or bottom surface of the main body 1 by a tie tape described later. It can be understood that the capacitance level gauge of FIG. 1 and the ultrasonic level gauge of FIGS. 2A-2B can be attached to the outer surface of the main body 1, so that the sealing structure of the main body 1 is not damaged at all, and sterilization and leakage prevention are not required. . When the ultrasonic level gauge 2 is adhered to the bottom surface, a corresponding base may be provided on the bottom surface of the drainage bottle 10 to provide a flat bottom surface so that the drainage bottle 10 can be stably placed on the ground below the bed. Alternatively, the drainage bottle 10 can be suspended from the bed frame of the hospital bed using a structure such as a hook.

FIG. 3 is a schematic structural view of a multifunctional drainage bottle according to another exemplary embodiment of the present application. The multi-function drainage bottle 10 of Figure 3 is substantially identical to that of Figure 1, except that the monitoring device 2 includes a radar level gauge. As shown in FIG. 3, the radar level gauge 2 is mounted on the top of the main body 1 of the drainage bottle 10. The monitoring principle of the radar level gauge 2 is similar to that of the ultrasonic level gauge, and also sends a signal to the drainage liquid, and receives an echo signal reflected by the liquid level of the drainage liquid, according to the time difference between the transmission time and the echo reception time, and The propagation speed of the signal in the corresponding medium is calculated, and the stroke of the signal is calculated to determine the liquid level of the drainage liquid. The difference is that the radar level gauge emits an electromagnetic wave signal. Since the penetration ability of the electromagnetic wave signal is weaker than the ultrasonic wave, in some embodiments, preferably, the top of the main body 1 has an opening, and the radar level gauge 2 can Mounted at the opening at the top of the body 1. Figure 4 shows a typical construction of a radar level gauge having a centrally located flange, a circuit portion above the flange, and an antenna portion below the flange. A flange can be placed over the opening at the top of the body 1 such that the antenna emits a monitoring signal toward the underlying drainage fluid. An example of a specific mounting structure of the radar level gauge 2 will be described in further detail below.

FIG. 5 is a functional block diagram of a monitoring device 2 in accordance with an exemplary embodiment of the present application. As shown in FIG. 5, the monitoring device 2 includes a signal acquisition unit 21, a signal processing unit 22, and a display unit 23. The signal acquisition unit 21 is configured to collect the drainage liquid level signal and transmit the collected signal to the signal processing unit 22. For example, the signal acquisition unit 21 may acquire a capacitance change signal, an ultrasonic signal, an electromagnetic wave signal, and the like, which are described above to indicate the liquid level of the drainage liquid, convert it into an electrical signal as needed for subsequent processing, and provide the acquired signal. Signal processing unit 22. The signal processing unit 22 can process the signal from the signal acquisition unit 21, determine the liquid level by capacitance change, or calculate the signal stroke by the time difference between signal transmission and reception, thereby determining the liquid level. The signal processing unit 22 can transmit the determined drain liquid level as a processing result to the display unit 23 for real-time display. The drainage bottle is often placed at the bottom of the bed during use. Therefore, by providing the display unit 23, the observation of the liquid level of the drainage liquid can be made more intuitive and convenient, and the content displayed by the display unit 23 can be selected according to specific needs.

In some embodiments, the signal acquisition unit 21 may repeatedly acquire signals indicative of the level of the liquid at a certain frequency such that the signal processing unit 22 may determine the level of the liquid at different times, maintaining continuous monitoring of the level of the liquid. In some embodiments, the signal processing unit 22 may also determine the rate of change of the liquid level based on the liquid level height values at different times, and thus the drainage speed may be determined. In the prior art, whether it is a photoelectric liquid level sensor or a magnetic plastic float type water level pipe, the working principle can be summarized as a result control, that is, when the liquid level rises to a predetermined height, this situation is fed back. In the present invention, as described above, the liquid level monitoring can be realized as process control, that is, the entire drainage process is monitored in real time, and the monitoring accuracy can be determined according to the monitoring frequency. In the above manner, the height change can be collected and fed back in real time during the process of gradually increasing the height of the drain liquid. Such a control method can not only determine the liquid level by the signal processing unit 22, but also determine the liquid level. Change (rise) speed to determine the drainage speed. The acquisition of these speeds is very important because there is a short-term sudden increase in the amount of drainage fluid in the clinic. If this situation cannot be detected in time and the corresponding countermeasures are taken, it will easily lead to delays in major illnesses. It will seriously endanger the health and even life of the patient. In the present invention, such a change in the drainage volume can be found in time by determining the drainage speed.

In some embodiments, the monitoring device 2 may further include an alarm unit 24 for alerting when the drain fluid level or the drain fluid velocity reaches or exceeds a set value. For example, as described above, the monitoring device 2 can monitor the level of the drainage liquid level or the speed of the liquid level change of the drainage liquid (ie, the drainage speed) by various means, when the liquid level of the drainage liquid or the rate of change thereof reaches a predetermined value, The alarm unit 24 can be triggered to implement an alarm. It should be understood that a plurality of such predetermined values may be set and the alarm unit 24 may be arranged to issue different levels of alarm signals for different predetermined values. For example, when the liquid level reaches the first predetermined value, the alarm unit 24 can emit a flashing alarm signal through the indicator light; when the liquid level reaches a second, higher predetermined value, the alarm unit 24 can emit a flashing alarm signal through the indicator light. And at the same time, an audible alarm signal is sent through the buzzer. Through the setting of the alarm unit 24, in the case of personnel oversight, the dangerous situation can be prompted by the form of sound and light alarm to minimize the medical risk, so as to early detection, early warning, early recording and early processing.

As previously mentioned, the capacitance level gauge and the ultrasonic level gauge can be directly adhered to the outer surface of the body 1 of the drainage bottle 10, and the radar level gauge needs to be mounted at the opening at the top of the body 1, Figure 6-10B Such an exemplary mounting manner is shown, wherein FIG. 6 shows a side view of a multifunctional drainage bottle including a mounting structure, and FIG. 7 shows a structural schematic view of a cover of the multifunctional drainage bottle, and FIG. 6 is a top view of the multifunctional drainage bottle, in which the respective pipes are omitted, and FIG. 9 is a partial side view of the multifunctional drainage bottle of FIG. 6, in which the respective pipes are omitted, and FIGS. 10A and 10B are respectively the tie of FIG. The belt is connected to the first slider and the second slider.

As shown in FIGS. 6-10B, the main body 1 includes an open portion (opening) 14 at the top for mounting the radar level gauge 2, and a cover for sealing the open portion 14 when the radar level gauge 2 is not installed. The body 13, the sealing portion 15 may also be provided with a sealing ring 15, such as a rubber sealing ring, for sealing the gap between the radar level gauge 2 and the main body 1. For example, the flange of the radar level gauge 2 can be overlaid on the sealing ring 15 and tied by the strap 19 described below. The main body 1 further includes two guide rails 31 and two strap structures 19 respectively disposed on opposite sides of the main body 1. The two ends of the two strap structures 19 can be fixedly connected to the corresponding first sliders 17, respectively. The block 17 can be inserted into the groove of a guide rail 31 and slid along the guide rail 31. The other ends of the two cable tie structures 19 can be respectively inserted into the corresponding slots on the second slider 18, and the cable tie structure 19 can be The card slot on the two sliders 18 moves in one direction, and when attempting to move in the reverse direction, the latches on the latches can be caught by the slots of the second slider 18, thereby tightening the movable end of the strap 19, that is, The cable tie 19 can be tightened. The second slider 18 can be inserted into and slid into the groove of the other guide rail 31. Thus, the radar level gauge 2 can be bound to the open portion 14 at the top of the body 1 by means of two straps 19. Since the main part of the radar level gauge 2 is located outside the drainage chamber 11, the drainage bottle can be removed after use, thereby achieving rapid re-use. The above installation structure realizes the between the radar level gauge 2 and the main body 1. Quick connection and removal, easy to operate. The guide rail 31 and the main body 1 are connected at the time of leaving the product, which are all plastic structures, and the first slider 17, the second slider 18 and the strap 19 can be distributed as parts, and the radar level gauge 2 is not installed. Previously, the cover 13 closes the open portion 14 to prevent dust from entering the main body 1. When the installation is required, the cover 13 is opened, and the height of the seal 15 is higher than the surface of the main body 1 through the radar level gauge and the seal ring. 15 fits to achieve a sealed installation. In actual use, the installation dimensions of different radar level gauges may be different. The mounting structure of the embodiment can realize the versatility of various structures, wherein the first slider 17 and the second slider 18 are along The sliding of the guide rail 31 can adjust the fixed width, and the fixing of the different lengths of the strap 19 can realize the fixing of the structure of different heights. By tightening the strap 19, the radar level gauge can be effectively tightly fitted. On the surface of the sealing ring 15, to ensure normal monitoring work, after the drainage liquid in the drainage bottle is filled, the disassembly of the radar level gauge 2 can be completed by cutting the cable tie 19, and then the cover 13 is tightly closed. In this way, the open portion 14 can be closed, and the leakage of the sealing ring 15 can be avoided.

In some embodiments, the surface of the strap 19 facing the main body 1 may also be provided with a plurality of elastic bumps 19a to ensure that the strap 19 is more closely attached to the radar level gauge 2.

It should be understood that the above mounting structure is not suitable for use in a radar level gauge, but can also be used, for example, in an ultrasonic level gauge. In the installation of the ultrasonic level timing using the above mounting structure, the open portion 14 on the main body 1 can be omitted, and the ultrasonic level gauge is directly attached to the outer surface of the main body 1. Moreover, the above mounting structure may be provided not only on the upper portion of the main body 1, but also on the lower portion of the main body 1 to bind the ultrasonic level gauge to the bottom surface of the main body 1.

It should also be understood that the above mounting structure is merely an example. In other embodiments, the radar level gauge and the ultrasonic level gauge can also be mounted to the main body 1 through other mounting structures, such as a threaded mounting structure, a snap structure, etc., which will not be described in detail herein.
