Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically refers to a nursing drainage device for an intensive care unit. Background Art

[0002] In the intensive care unit (ICU), many patients are unable to effectively drain their body fluids on their own due to their serious condition. These body fluids may include blood, pus, lymph, etc. If they cannot be discharged in time, they will pose a serious health threat to the patient, such as infection, organ dysfunction, and even life-threatening. Therefore, an effective drainage system is crucial for the recovery of ICU patients. At present, conventional ICU drainage technology mainly relies on negative pressure drainage devices. Such devices usually include a collection container, a drainage tube connected to the patient's body, and a device that generates negative pressure, such as a manual compression ball or an electric pump. Medical staff operate the negative pressure device to suck the accumulated fluid in the patient's body into the collection container. However, the existing ICU drainage technology has some obvious defects, which are mainly reflected in the following aspects.

[0003] Whether it is a manual compression ball or an electric pump, it is difficult for existing negative pressure devices to achieve precise control of the size of negative pressure. The operation of the manual compression ball depends on the experience and feel of medical staff, which is prone to unstable negative pressure, resulting in too fast or too slow drainage speed. Although the electric pump can set the negative pressure value, in actual operation, due to factors such as changes in drainage line resistance and changes in patient position, the preset negative pressure value often cannot meet the actual needs, but it cannot be adjusted in real time. At the same time, excessive negative pressure can cause many harms to patients, such as tissue damage, bleeding, pain and other problems. For example, electrolyte disorders, a large amount of drainage in a short period of time will cause electrolyte imbalance in the patient's body. For example, drastic changes in negative pressure will cause discomfort to patients. However, the actual situation is that after the effusion accumulates in the body, only a slight negative pressure guide is needed to achieve drainage, so a soft and precisely adjustable negative pressure is essential for ICU drainage.

[0004] Existing drainage devices usually take a long time to drain the accumulated fluid, so it takes a long time for the collection container to be full of accumulated fluid. During this time, the liquid in the container may coagulate, such as blood coagulation, forming a blood clot. The coagulation of accumulated fluid will increase the resistance of the drainage tube, affect the drainage efficiency, and even cause the drainage tube to be blocked.

[0005] When the collection container is full, it needs to be replaced. The existing replacement operation usually requires disconnecting the drainage line, removing the collection container, and then connecting a new collection container. This operation process is cumbersome and time-consuming, which increases the workload of medical staff. More importantly, in the process of disconnecting the drainage line, it is necessary to use a clamp to clamp the drainage tube to prevent the effusion from flowing back. If the clamp is clamped too loosely, it may cause the effusion to flow back, causing contamination or infection; if the clamp is clamped too tightly, it may damage the drainage tube. Medical staff may make mistakes when operating the clamp, resulting in safety accidents. Summary of the invention

[0006] In view of the above situation, the present invention provides an intensive care unit nursing drainage device, which can monitor and accurately adjust the negative pressure to form a soft and precise negative pressure to ensure the safety of the drainage process. It is also equipped with an anti-coagulation design to effectively prevent the accumulated fluid from coagulating in the collection container. Through the clever combination with the negative pressure mechanism, the transfer of the accumulated fluid can be completed without disconnecting the drainage pipeline. The operation is simple and quick, and the risk of reflux and contamination can be effectively avoided, thereby reducing the workload of medical staff.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes an intensive care unit nursing drainage device, including a drainage transfer tank, a cover body is provided at the upper end of the drainage transfer tank, a drainage sleeve and a liquid collection tube are respectively sealed on the cover body, a flexible and controllable two-way drainage mechanism is provided on the cover body, drainage liquid monitoring and analysis mechanisms are provided on both sides of the drainage sleeve, a fast-response liquid level monitoring mechanism is provided on the side of the drainage transfer tank, an ultrasonic crushing and dredging mechanism is provided at the lower part of the drainage transfer tank, and a pressure gauge is connected to the cover body.

[0008] Furthermore, the flexible controllable two-way drainage mechanism includes a two-way air pump and a pressure regulating pipe. The output end of the two-way air pump is connected and fixedly arranged on the upper side of the cover body. The two-way air pump has both suction and exhaust functions, and can realize the drainage transfer tank to inhale gas from the outside and discharge the gas in the drainage transfer tank through switch control. One end of the pressure regulating pipe is vertically connected and fixedly arranged on the upper side of the cover body. The two-way air pump and the pressure regulating pipe are respectively arranged on the two edges of the middle part of the cover body to increase the length of the airflow movement. The free end of the pressure regulating pipe is arranged with its back to the drainage transfer tank. The free end of the pressure regulating pipe is closed. The pressure regulating pipe is coaxially provided with a semicircular opening on the closed end. A clamping ring is coaxially fixed on the closed end of the pressure-regulating tube, and a rotating shaft is rotatably engaged in the clamping ring. A semicircular baffle is coaxially fixed on one end of the rotating shaft. The semicircular baffle is the same size as the semicircular opening, so that the semicircular baffle can close the semicircular opening. The inner side of the semicircular baffle is in close contact with the closed end of the pressure-regulating tube, and a circular groove is provided in the middle of the inner side of the semicircular baffle, and a pressure spring is fixed in the circular groove. A clamping column is fixed at one end of the pressure spring, and the clamping column is tightly arranged in the circular groove. The pressure-regulating tube is provided with a recess on the outer side of the middle of the semicircular opening, and the hemispherical end of the clamping column is in close contact with the recess to achieve the positioning of the angle of the semicircular baffle.

[0009] Furthermore, the vertical section of the drainage sleeve is sealed and inserted in the drainage transfer tank, and the lower end of the vertical section of the drainage sleeve is threadedly connected to a first one-way valve, and the one-way flow direction of the first one-way valve is from the outside of the drainage transfer tank to the inside of the drainage transfer tank. One end of the horizontal section of the drainage sleeve is plugged into the drainage tube connected to the patient, and the vertical section of the liquid collection tube is sealed and inserted in the drainage transfer tank, and the lower end of the vertical section of the liquid collection tube is threadedly connected to a second one-way valve, and the one-way flow direction of the second one-way valve is from the inside of the drainage transfer tank to the outside of the drainage transfer tank. One end of the horizontal section of the liquid collection tube is arranged downward to facilitate the collection of the extracted drainage fluid through a container, and the first one-way valve and the second one-way valve are arranged at the same height and close to the bottom of the drainage transfer tank.

[0010] Furthermore, the drainage fluid monitoring and analysis mechanism includes a base, which is symmetrically arranged on both sides of the drainage sleeve, and is fixed on the upper side of the cover body. A first laser transmitter is fixed on one of the bases, and a first receiver is fixed on the other base, which can sense the laser intensity and generate and transmit a wireless signal of corresponding intensity. The transmitting end of the first laser transmitter is facing the drainage sleeve and the receiving end of the first receiver.

[0011] Furthermore, the quick response liquid level monitoring mechanism includes a second laser transmitter, a second receiver, a third laser transmitter and a third receiver. The second laser transmitter and the second receiver are fixedly arranged on the outer side of the upper part of the drainage transfer tank, the second laser transmitter and the second receiver are located below the cover body, the transmitting end of the second laser transmitter faces the drainage transfer tank and the receiving end of the second receiver, the third laser transmitter and the third receiver are fixedly arranged on the outer side of the lower part of the drainage transfer tank, the third laser transmitter and the third receiver are located above the lower end of the first one-way valve, and the transmitting end of the third laser transmitter faces the drainage transfer tank and the receiving end of the third receiver.

[0012] Furthermore, the ultrasonic disintegration and dredging mechanism includes an ultrasonic generator, which is symmetrically fixed on the outside of the drainage transfer tank. An ultrasonic transducer is fixed at one end of the ultrasonic generator. The ultrasonic transducer seals and penetrates the side wall of the drainage transfer tank and extends into the interior of the drainage transfer tank. The high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the ultrasonic transducer and propagated into the effusion in the drainage transfer tank, thereby achieving the disintegration and dredging of the coagulated effusion.

[0013] Furthermore, the drainage transfer tank and the drainage sleeve are made of transparent material and can be penetrated by laser.

[0014] Furthermore, the cover body is threadedly and hermetically connected to the drainage transfer tank, and the two-way air pump, the pressure gauge and the pressure regulating pipe are all threadedly and hermetically connected to the cover body, which is convenient for disassembly and cleaning.

[0015] Furthermore, the dial of the barometer and the free end of the pressure regulating tube are arranged in the same direction, which is convenient for observation and operation.

[0016] Furthermore, when the second receiver receives a weakened laser intensity signal, it will transmit a wireless signal to control the two-way air pump to shut down; when the third receiver receives an enhanced laser intensity signal, it will transmit a wireless signal to control the two-way air pump to shut down, thereby ensuring that the liquid level in the drainage transfer tank is always maintained within a reasonable range.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The flexible and controllable two-way drainage mechanism adopted by the present invention controls the gas in and out of the drainage transfer tank through a two-way air pump, and uses the Bernoulli principle to change the air flow speed by adjusting the opening of the semicircular baffle on the pressure regulating tube, thereby accurately controlling the negative pressure in the drainage transfer tank. This design avoids the problem that traditional negative pressure devices are difficult to accurately control negative pressure and the negative pressure is too strong. It can achieve soft and accurate negative pressure adjustment according to the patient's specific situation and drainage needs, ensuring that the drainage process is safe and effective. Medical staff can monitor the negative pressure value in the drainage transfer tank in real time by observing the reading of the barometer, and summarize the negative pressure corresponding to different semicircular baffle angles based on experience, so as to achieve flexible response to different drainage conditions and improve drainage efficiency.

[0018] (2) The present invention ingeniously combines a flexible and controllable two-way drainage mechanism with a liquid collection tube and a first one-way valve and a second one-way valve, thereby achieving the transfer of accumulated fluid without disconnecting the drainage pipeline. When the accumulated fluid in the drainage transfer tank needs to be drained, it is only necessary to close the semicircular baffle fan and turn on the suction function of the two-way air pump, so that external air can enter the drainage transfer tank and discharge the accumulated fluid through the liquid collection tube. The design of the first one-way valve and the second one-way valve ensures that the accumulated fluid can only flow in one direction, thus preventing the accumulated fluid from flowing back into the patient's body, and effectively reducing the risk of contamination and infection.

[0019] (3) The ultrasonic disintegration and dredging mechanism of the present invention generates high-frequency mechanical vibrations through an ultrasonic generator, which acts on the accumulated fluid in the drainage transfer tank, and can effectively break up and dredge the solidified accumulated fluid, ensure the smooth flow of the drainage pipeline, improve the drainage efficiency, and avoid blockage and risks caused by the solidification of the accumulated fluid.

[0020] (4) The fast response liquid level monitoring mechanism adopted by the present invention utilizes a second laser transmitter, a second receiver, a third laser transmitter and a third receiver to monitor the liquid level of the accumulated liquid in the drainage transfer tank in real time. When the liquid level is too high or too low, the receiver will send a signal to control the shutdown of the two-way air pump, thereby automatically controlling the drainage and discharge of the accumulated liquid, avoiding abnormal operation of the device due to excessively high or low liquid levels, and reducing the workload of medical staff.

[0021] (5) During the drainage process, the drainage fluid monitoring and analysis agency continuously monitors the concentration and composition changes of the drainage fluid to assist medical staff in making a diagnosis. This function of continuously monitoring the concentration and composition changes of the drainage fluid can provide medical staff with more comprehensive and timely patient information, helping them to more accurately judge the patient's recovery status, adjust the treatment plan in a timely manner, and improve the treatment effect.

[0022] (6) The cover of the device of the present invention is connected to the drainage transfer tank by threaded sealing, and the two-way air pump, pressure gauge and pressure regulating tube are all connected to the cover by threaded sealing, which is convenient for disassembly and assembly, and convenient for medical staff to clean and disinfect, thereby ensuring the hygiene and safety of the device.

The base 61 is fixed on the upper side of the cover body 2, and a first laser emitter 62 is fixed on one of the bases 61, and a first receiver 63 is fixed on the other base 61. The emitting end of the first laser emitter 62 is directly opposite to the receiving end of the drainage sleeve 3 and the first receiver 63.

[0038] The quick response liquid level monitoring mechanism 7 includes a second laser transmitter 71, a second receiver 72, a third laser transmitter 73 and a third receiver 74. The second laser transmitter 71 and the second receiver 72 are fixedly arranged on the upper outer side of the drainage transfer tank 1. The second laser transmitter 71 and the second receiver 72 are located below the cover 2. The transmitting end of the second laser transmitter 71 faces the drainage transfer tank 1 and the receiving end of the second receiver 72. The third laser transmitter 73 and the third receiver 74 are fixedly arranged below the drainage transfer tank 1. On the outside of the drainage transfer tank 1, the third laser emitter 73 and the third receiver 74 are located above the lower end of the first one-way valve 31. The emitting end of the third laser emitter 73 is facing the drainage transfer tank 1 and the receiving end of the third receiver 74. The ultrasonic crushing and dredging mechanism 8 includes an ultrasonic generator 81, which is symmetrically fixed on the outside of the drainage transfer tank 1. An ultrasonic transducer 82 is fixed at one end of the ultrasonic generator 81. The ultrasonic transducer 82 seals and penetrates the side wall of the drainage transfer tank 1 and then extends into the interior of the drainage transfer tank 1.

[0039] Among them, the drainage transfer tank 1 and the drainage sleeve 3 are made of transparent material, the cover body 2 is threadedly sealed with the drainage transfer tank 1, the two-way air pump 51, the pressure gauge 9 and the pressure regulating tube 52 are all threadedly sealed with the cover body 2, the dial of the pressure gauge 9 and the free end of the pressure regulating tube 52 are arranged in the same direction, and the second receiver 72 will transmit a wireless signal to control the two-way air pump 51 to be turned off when the laser intensity signal is weakened, and the third receiver 74 will transmit a wireless signal to control the two-way air pump 51 to be turned off when the laser intensity signal is enhanced.

[0040] During specific use, it is necessary to assemble the various parts of the device that have been disinfected and cleaned, and seal the vertical sections of the drainage sleeve 3 and the liquid collection tube 4 on the cover body 2. At this time, the drainage sleeve 3 is located between the first laser emitter 62 and the first receiver 63, and the lower ends of the drainage sleeve 3 and the liquid collection tube 4 are made to be at the same height. Then, the first one-way valve 31 and the second one-way valve 41 are threadedly connected to the lower ends of the drainage sleeve 3 and the liquid collection tube 4, respectively. Then, a small amount of water is injected into the drainage transfer tank 1. After the cover body 2 and the drainage transfer tank 1 are sealed and threadedly connected, the second one-way valve 41 and the first one-way valve 31 are immersed in the water and close to the bottom of the drainage transfer tank 1. At this time, the first one-way valve 31 and the second one-way valve 41 are located below the third laser emitter 73. At this time, the pressure gauge 9, the two-way air pump 51 and the pressure regulating tube 52 are threadedly connected to the cover body 2 at the corresponding positions, and the device is assembled.

[0041] The drainage transfer tank 1 is fixedly placed beside the patient, one end of the drainage tube inserted into the patient's body is plugged into the drainage sleeve 3, and the exhaust function of the two-way air pump 51 is turned on. At this time, the two-way air pump 51 extracts the gas in the drainage transfer tank 1. At this time, due to the setting of the semicircular opening 53, the pressure regulating tube 52 and the drainage transfer tank 1 are connected to the outside world. Part of the gas passes through the pressure regulating tube 52 and the drainage transfer tank 1 and is discharged from the outlet of the two-way air pump 51. According to the Bernoulli principle, the circulating airflow reduces the gas pressure on the upper part of the drainage transfer tank 1, and the opening degree of the semicircular opening 53 is changed by rotating the semicircular baffle 56, thereby changing the gas pressure on the upper part of the drainage transfer tank 1 by changing the flow rate. When the air pressure decreases and forms a negative pressure, it will force the gas space in the drainage transfer tank 1 to become smaller, so that the drainage sleeve 3 draws the accumulated fluid in the drainage tube out into the drainage transfer tank 1, so that the accumulated fluid in the drainage transfer tank 1 increases to supplement the space. Due to the first one-way valve The one-way flow direction of 31 is from the outside of the drainage transfer tank 1 to the inside of the drainage transfer tank 1, and the one-way flow direction of the second one-way valve 41 is from the inside of the drainage transfer tank 1 to the outside of the drainage transfer tank 1. Therefore, the negative pressure can only allow the patient's accumulated fluid to enter the drainage transfer tank 1, and will not allow the air outside the liquid collection tube 4 to enter from the liquid collection tube 4. While changing the angle of the semicircular baffle 56, the value of the barometer 9 can be observed at all times to judge and summarize the negative pressure corresponding to different angles, so as to accurately adjust the reasonable negative pressure for drainage. Due to the provision of the semicircular opening 53, the change of air pressure is slow under the Bernoulli principle, and the negative pressure itself is also weak, which will not cause the strong negative pressure in the closed vacuum condition to quickly draw out the accumulated fluid and is difficult to control. Sufficient adjustment time and fault tolerance are given, and as the medical staff gain more experience in use, it is easier to grasp the angle of the semicircular baffle 56 and to adapt to different drainage conditions.

[0042] When the accumulated liquid in the drainage transfer tank 1 increases and approaches the cover body 2, it is easy to be pumped out by the two-way air pump 51, affecting the operation of the device. At this time, the quick response liquid level monitoring mechanism 7 will play a role. When the liquid level of the accumulated liquid is higher than the second laser transmitter 71, the accumulated liquid will block the second receiver 72 from receiving the laser signal. The second receiver 72 wirelessly transmits the laser weakened signal to the control module of the two-way air pump 51, thereby controlling the two-way air pump 51 to shut down and stop draining. At this time, the semicircular baffle fan 56 is rotated to move the column 58 to the position of the recess 59, so that the hemispherical end of the column 58 is in close contact with the recess 59, thereby realizing the positioning of the semicircular baffle fan 56. At this time, the semicircular baffle fan 56 completely closes the semicircular opening 53, turning on the suction function of the two-way air pump 51. , fill the drainage transfer tank 1 with external gas. Since the semicircular opening 53 is blocked, the increased gas can only drain the accumulated liquid in the drainage transfer tank 1. Due to the action of the first one-way valve 31 and the second one-way valve 41, the accumulated liquid can only be discharged from the liquid collection tube 4 and will not flow back into the drainage sleeve 3, so it will not cause the traditional reflux hazard. The accumulated liquid is discharged from the liquid collection tube 4 and collected in the container until the liquid level of the accumulated liquid is below the third laser transmitter 73. The third receiver 74 wirelessly transmits the laser-enhanced signal to the control module of the two-way air pump 51, thereby controlling the two-way air pump 51 to close, thereby stopping the discharge of the liquid, and preventing the liquid level of the accumulated liquid from dropping below the second one-way valve 41 and the first one-way valve 31 to affect the operation of the device.

[0043] When the accumulated fluid in the drainage transfer tank 1 is stored for too long and solidifies, the decreased fluidity will hinder normal drainage. At this time, the ultrasonic generator 81 is turned on, and the high-frequency oscillation signal emitted by the ultrasonic generator 81 is converted into high-frequency mechanical oscillation by the ultrasonic transducer 82 and propagated into the accumulated fluid in the drainage transfer tank 1, thereby breaking up and clearing the solidified accumulated fluid.

[0044] During the drainage process, due to the difference in light transmittance of different types of body fluids, such as blood, pus, lymph, etc., the intensity of the laser signal received by the first receiver 63 will change with the change in the concentration and composition of the drainage fluid. By analyzing the laser signal intensity change curve received by the first receiver 63, the concentration and approximate composition of the drainage fluid can be continuously judged, thereby helping medical staff to understand the patient's drainage situation in real time.
