Description

Technical Field

[0001] The present invention relates to the medical field, and particularly to a closed thoracic drainage device for respiratory care. Background Art

[0002] Closed thoracic drainage is an important medical technique for treating conditions such as pleural effusion, pneumothorax, or infection in the thoracic cavity. The thoracic cavity is composed of the chest wall, diaphragm, and mediastinum, containing important organs such as the lungs, heart, and large blood vessels. The pleural cavity is the potential space between the visceral pleura and the parietal pleura, which normally contains a small amount of lubricating fluid to reduce friction during breathing. When there is pleural effusion, pneumothorax, hemothorax, empyema, or other abnormal accumulations in the thoracic cavity, these accumulations can compress the lung tissue, affect respiratory function, and even endanger life. Early thoracic drainage techniques mainly used open drainage, but this method was prone to infection and had limited effectiveness. With the development of medical technology, closed drainage techniques have gradually matured, maintaining the negative pressure in the pleural cavity through a water seal bottle or modern drainage devices to prevent air reflux and reduce the risk of infection. The core principle of closed drainage devices is to use a water seal or one-way valve mechanism to ensure that fluid or gas in the thoracic cavity can be smoothly discharged while preventing external air from entering the thoracic cavity. Modern drainage systems, such as the Heimlich valve and digital drainage devices, further improve the convenience and safety of operation and can monitor the drainage situation in real time. The indications for closed thoracic drainage are extensive, including pneumothorax, hemothorax, empyema, and pleural effusion, etc., but it should be used with caution in cases of coagulation disorders or severe cardiopulmonary insufficiency. In terms of operation techniques, closed drainage requires accurate positioning of the puncture point, local anesthesia, insertion of the drainage tube, and connection of the drainage device. After the operation, it is also necessary to closely monitor the drainage situation and prevent complications such as infection.

[0003] In the prior art, for example, Patent Publication No. CN118924975A discloses a closed thoracic drainage device that monitors the drainage situation through an information feedback component to facilitate medical staff to detect problems in a timely manner. Patent Publication No. CN116983491A discloses a closed thoracic drainage bottle that can monitor the amount of pleural fluid in the collection bottle and automatically dredge the pipeline when it is blocked during the drainage process. Patent Publication No. CN109833528A discloses an intelligent visual closed thoracic drainage system that assists the drainage process through a data collection device that monitors, collects, and displays data on the closed thoracic drainage device and the human body state.

[0004] During the process of closed thoracic drainage, patients usually need to maintain a semi-recumbent or lateral position to ensure effective drainage of the accumulated fluid. During the semi-recumbent or lateral position of the patient, it is possible to guide the patient to change the body position, which helps to fully drain the accumulated fluid. The principle is that the accumulated fluid may accumulate in different parts of the thoracic cavity due to gravity. If the patient maintains the same body position for a long time, the fluid may accumulate in some parts, and changing the body position can promote the release of the accumulated fluid in each part. In the prior art, since the patient is not supervised at all times, it is difficult to know what kind of body position changes the patient has made, and it is also difficult to know whether the process of the patient's body position change can fully release the accumulated fluid in each part of the thoracic cavity. Summary of the Invention

[0005] To solve the above problems, the present invention provides a closed thoracic drainage device for respiratory care, which is used to monitor whether the patient fully changes the body position during the process of thoracic cavity effusion to achieve the preset effect of fluid release.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A closed thoracic drainage device for respiratory care includes a drainage device and a wearable monitor;

[0007] The drainage device is used to drain the accumulated fluid in the patient's thoracic cavity;

[0008] The wearable monitor includes a controller, an inertial sensor, and a gyroscope. The wearable monitor is used to be worn on the patient's torso and move with the patient's torso;

[0009] The controller is used to obtain the acquisition information of the inertial sensor and the gyroscope, and judge the direction and amplitude of the patient's body position change during the drainage process; the controller is also used to preset the body position change standard, and the change standard is the number of times the patient completes the preset direction and amplitude change during the drainage process. The controller is used to judge whether the patient completes the body position change standard during the drainage process based on the acquisition information of the inertial sensor and the gyroscope.

[0010] The beneficial effects of adopting the above solution are as follows:

[0011] 1. In this solution, the user can use the drainage device to drain the accumulated fluid in the patient's thoracic cavity. After the drainage operation of the drainage device is completed, the wearable monitor is worn on the patient's torso. The wearable monitor is provided with an inertial sensor and a gyroscope. When the patient changes the body position, the wearable monitor will change the position along with the patient's body position change, so as to record the process of the patient's body position change.

[0012] 2. In this solution, medical staff can formulate body position change standards, that is, set the body position change indicators that patients need to complete during the drainage of pleural effusion. Adequate body position changes during the drainage of pleural effusion can promote the release of pleural effusion in various parts of the chest. In the prior art, it is difficult for medical staff to supervise patients' body position changes at all times. Even if supervision is carried out, it is difficult to judge whether the amplitude and direction of patients' multiple body position changes meet the requirements by the naked eye.

[0013] During the drainage of pleural effusion in the patient's chest, the controller will automatically record the body position changes and amplitudes of the patient in various directions, and judge whether the patient has completed the body position change indicators according to the preset body position change standards, so as to achieve the effect of adequately promoting the release of pleural effusion.

[0014] Furthermore, the controller is also used to judge the frequency of the patient's completion of the preset direction and amplitude changes during the drainage process. When the frequency of the patient's completion of the preset direction and amplitude changes per unit time is less than the preset value, the controller issues an alarm.

[0015] Beneficial effects: In addition to promoting the final effect of pleural effusion release, the patient's body position change can also reduce the accumulation of tissues or fibrin around the drain, reduce the risk of drain blockage, and at the same time improve the patient's stress and ventilation conditions, and prevent complications such as pressure sores. However, different from meeting the body position change standards, the subsequent effects need to maintain a certain body position frequency to achieve the corresponding effects. Therefore, frequency detection is introduced to enable the patient to perform a more standardized and beneficial body position change process.

[0016] Furthermore, the drain includes a drainage tube, the drainage tube is detachably connected to a drainage bottle, and a one-way valve is provided in the drainage tube;

[0017] A viscosity sensor and a flow sensor are provided in the drainage tube. The controller is used to obtain the acquisition information of the viscosity sensor and the flow sensor, and judge the severity of the patient's pleural effusion based on the viscosity data and flow data of the acquisition information. The controller sets the body position change standards according to the severity of the patient's pleural effusion, and the number of times of completing the preset direction and amplitude changes is proportional to the severity of the patient's pleural effusion.

[0018] Beneficial effects: The drainage tube is used to drain the pleural effusion in the patient's chest cavity, and the drainage bottle is used to collect the drained pleural effusion in the chest cavity. The one-way valve can prevent the backflow of the effusion. The body position change standard can be set according to the severity of the patient's effusion, that is, when the patient has a large amount of effusion and a high viscosity of the effusion, a stronger promotion effect on the release of the effusion is required to ensure the effective remission of the patient's condition. Therefore, a viscosity sensor and a flow sensor are provided in the drainage tube, which can feedback the amount of the patient's effusion and the viscosity of the effusion through the flow sensor and the viscosity sensor. Among them, when the patient has a large amount of effusion, the hydrostatic pressure of the effusion is large, and the unit time flow rate released can feedback the hydrostatic pressure and thus feedback the amount of the effusion. By detecting the amount of the patient's effusion and the viscosity of the effusion, the body position change standard is modified to adapt to patients with different severities of pleural effusion.

[0019] Furthermore, a negative pressure aspirator is also provided on the drainage tube, and the controller is used to set the suction force of the negative pressure aspirator according to the severity of the patient's pleural effusion.

[0020] Beneficial effects: The negative pressure aspirator can generate negative pressure to promote the drainage process and can dynamically set the suction force of the negative pressure aspirator according to the severity of the patient's pleural effusion.

[0021] Furthermore, a paired Hall sensor is provided between the drainage tube and the drainage bottle. The Hall sensor is used to detect the matching state of the drainage tube and the drainage bottle. When the matching state is that the drainage bottle is detached from the drainage tube, the controller controls the one-way valve to close.

[0022] Beneficial effects: The Hall sensor can detect the change of the magnetic field to judge the matching situation of the drainage tube and the drainage bottle. After the drainage tube and the drainage bottle are detached, the controller controls the one-way valve to close, thereby truncating the release of the effusion and reducing the amount of the effusion spilled outside the drainage bottle.

[0023] Furthermore, the wearable monitor includes two paired blocks. The inertial sensor and the gyroscope are both fixedly connected to the paired blocks. Adhesive tapes are provided at the bottoms of the paired blocks. The paired blocks are respectively used to be pasted on both sides of the patient's chest drainage opening. An optoelectronic transmissive sensor is provided between the paired blocks, and the optoelectronic transmissive sensor is used to detect whether the drainage tube is detached from the chest drainage opening.

[0024] Beneficial effects: The wearable monitor is two paired blocks, which are respectively pasted on both sides of the patient's chest drainage opening. The optoelectronic transmissive sensor can continuously perform transmissive detection, and judge whether the drainage tube is detached from the chest drainage opening through the change of the optical path, so as to respond to the situation of the drainage tube falling off in a timely manner.

[0025] Furthermore, a telescopic member is further included. Both ends of the telescopic member are fixedly connected to the paired blocks. The controller is used to control the telescopic member to contract after the optoelectronic transmissive sensor detects that the drainage tube is detached from the chest drainage opening, so that the paired blocks drive the skin on both sides of the chest drainage opening to tighten the chest drainage opening.

[0026] Beneficial effects: When the drainage tube falls off, the effusion will still be released from the patient's thoracic drainage orifice. At this time, the effusion will not flow into the drainage bottle through the drainage tube, but will be directly released onto the hospital bed or into the ward. The telescopic member can contract when it detects that the drainage tube has fallen off, thereby tightening the thoracic drainage orifice, reducing the release of the effusion, and reducing the contamination of the hospital bed or ward by the effusion.

[0027] Furthermore, a water level sensor is provided inside the drainage bottle.

[0028] Beneficial effects: The water level sensor can judge the loading state of the drainage bottle, thereby prompting medical staff to replace the drainage bottle.

[0029] Furthermore, the controller is also provided with a wireless component. The controller is used to send an alarm to the medical staff through the wireless component when the drainage bottle is detached from the drainage tube, when the drainage tube is detached from the thoracic drainage orifice, and when the detection data of the water level sensor exceeds a preset value.

[0030] Beneficial effects: The wireless component can provide remote communication capabilities, thereby remotely sending messages to the medical staff. When the drainage bottle is detached from the drainage tube, the drainage tube is detached from the thoracic drainage orifice, and the detection data of the water level sensor exceeds the preset value, medical staff are respectively required to go to the patient to reconnect the drainage bottle and the drainage tube, re-fix the drainage tube, and replace the drainage bottle.

[0031] Furthermore, the drainage bottle is fixedly connected with a towing rope, and a pull ring is provided at one end of the towing rope away from the drainage bottle.

[0032] Beneficial effects: The patient may have needs such as getting out of bed and moving around. The towing rope and the pull ring can enable the patient to lift the drainage bottle and keep the drainage bottle in a position below the thoracic drainage orifice.

[0033] The additional aspects and advantages of the present invention will be partly given in the following description, partly will become obvious from the following description, or will be understood through the practice of the present invention. Description of the Drawings

[0043] The following is a further detailed description through specific embodiments:

[0044] Embodiment 1:

[0045] As shown in the Figures 1 - 5 accompanying drawings: A closed thoracic drainage device for respiratory care includes a drainage device 1 and a wearable monitor 2;

[0046] The drainer 1 is used to drain the fluid in the patient's chest cavity. The drainer 1 includes a drainage tube 5, the drainage tube 5 is detachably connected to a drainage bottle 6, and a one-way valve 7 is installed in the drainage tube 5.

[0047] The wearable monitor 2 includes a controller and two pairing blocks 12. Adhesive tapes 13 are fixedly pasted at the bottoms of the pairing blocks 12. The pairing blocks 12 are respectively used to be pasted on both sides of the patient's chest drainage opening. An inertial sensor 3 and a gyroscope 4 are bolted to the pairing blocks 12. The wearable monitor 2 is used to be worn on the patient's torso and move along with the patient's torso.

[0048] The controller is used to obtain the acquisition information of the inertial sensor 3 and the gyroscope 4, judge the direction and amplitude of the patient's body position change during the drainage process, and the controller is also used to preset the body position change standard. The change standard is the number of times the patient completes the preset direction and amplitude change during the drainage process. The controller is used to judge whether the patient completes the body position change standard during the drainage process based on the acquisition information of the inertial sensor 3 and the gyroscope 4.

[0049] During use, first, a chest drainage opening is constructed on the patient's torso through a drainage operation, and the drainage tube 5 is inserted into the patient's chest drainage opening to construct a stable drainage path. After the drainage operation of the drainer 1 is completed, the wearable monitor 2 is worn on the patient's torso. The wearable monitor 2 is provided with an inertial sensor 3 and a gyroscope 4. When the patient changes body position, the wearable monitor 2 will change its position along with the patient's body position change, thereby recording the process of the patient's body position change.

[0050] Medical staff can formulate a body position change standard, that is, set the body position change indicators that the patient needs to complete during the drainage of the fluid in the chest cavity. The patient performs sufficient body position changes during the drainage of the fluid in the chest cavity, which can promote the release of the fluid in various parts of the chest cavity. Usually, the patient needs to lie semi-recumbent or on the side for the drainage of the fluid in the chest cavity, and its function is to enable the fluid in the chest cavity to converge to the chest drainage opening under the action of gravity. However, due to the complex internal environment of the chest cavity caused by the patient's chest lesions, maintaining a single posture will cause fluid accumulation in the internal positions of the chest cavity. In the prior art, it is difficult for medical staff to supervise the patient's body position change all the time. Even if they do supervise, it is difficult to judge whether the amplitude and direction of the patient's multiple body position changes meet the requirements by the naked eye.

[0051] During the process of draining the fluid accumulated in the patient's chest cavity, the controller automatically records the patient's body position changes and amplitudes in various directions, and determines whether the patient has completed the body position change indicators and achieved a sufficient effect of promoting fluid release according to the preset body position change criteria. Medical staff can go to the patient's location for on-site confirmation at regular intervals or view the patient's body position change situation recorded by the controller through remote communication to guide the patient to perform corresponding actions and improve the fluid release effect. At the same time, when the fluid drainage ends, the medical staff can also check whether the patient has completed the body position change indicators through the controller and guide the patient to perform corresponding body position change actions before removing the drainage tube 5 to release the remaining fluid.

[0052] Embodiment 2:

[0053] The difference from the above embodiment is that the controller is also used to judge the frequency of the patient's completion of the preset direction and amplitude changes during the drainage process. When the frequency of the patient's completion of the preset direction and amplitude changes per unit time is less than the preset value, the controller issues an alarm. The controller can be electrically connected to a buzzer or an LED, etc., and transmit alarm information to the patient in the form of the buzzer beeping and the LED flashing.

[0054] In addition to promoting the final fluid release effect, the patient's body position changes can also reduce the accumulation of tissues or fibrin around the drain 1, reduce the risk of blockage of the drain 1, and at the same time improve the patient's stress and ventilation conditions and prevent complications such as pressure sores. However, different from meeting the body position change criteria, the subsequent effects need to maintain a certain body position frequency to achieve the corresponding effects. Therefore, frequency detection is introduced to enable the patient to perform a more standardized and beneficial body position change process.

[0055] Embodiment 3:

[0056] The difference from the above embodiment is that a viscosity sensor 8 and a flow sensor 9 are provided in the drainage tube 5. The controller is used to obtain the acquisition information of the viscosity sensor 8 and the flow sensor 9, and judge the severity of the patient's pleural effusion based on the viscosity data and flow data of the acquisition information. The controller sets the body position change criteria according to the severity of the patient's pleural effusion, where the number of times of completing the preset direction and amplitude changes is proportional to the severity of the patient's pleural effusion.

[0057] The drainage tube 5 is used to drain the pleural effusion in the patient's chest cavity, and the drainage bottle 6 is used to collect the drained pleural effusion. The one-way valve 7 can prevent the backflow of the effusion. The body position change standard can be set according to the severity of the patient's effusion, that is, when the patient has a large amount of effusion and a high viscosity of the effusion, a stronger promotion effect for effusion release is required to ensure the effective relief of the patient's condition. Therefore, a viscosity sensor 8 and a flow sensor 9 are provided in the drainage tube 5, which can feedback the amount of effusion and the viscosity of the effusion of the patient through the flow sensor 9 and the viscosity sensor 8. Among them, when the patient has a large amount of effusion, the hydrostatic pressure of the effusion is large, and the unit time flow rate released can feedback the hydrostatic pressure and thus feedback the amount of effusion. By detecting the amount of effusion and the viscosity of the effusion of the patient, the body position change standard is modified to adapt to patients with different severities of pleural effusion. In addition, the preset value of the frequency of completing the preset direction and amplitude change can also be dynamically adjusted based on the severity of the patient's pleural effusion.

[0058] Embodiment 4:

[0059] The difference from the above embodiment is that a negative pressure aspirator 10 is installed on the drainage tube 5, and the controller is used to set the suction force of the negative pressure aspirator 10 according to the severity of the patient's pleural effusion.

[0060] The negative pressure aspirator 10 can generate negative pressure to promote the drainage process, and can dynamically set the suction force of the negative pressure aspirator 10 according to the severity of the patient's pleural effusion.

[0061] Embodiment 5:

[0062] The difference from the above embodiment is that a paired Hall sensor 11 is provided between the drainage tube 5 and the drainage bottle 6. The Hall sensor 11 is used to detect the matching state of the drainage tube 5 and the drainage bottle 6. When the matching state is that the drainage bottle 6 is separated from the drainage tube 5, the controller controls the one-way valve 7 to close.

[0063] An optoelectronic pair sensor 15 is installed between the paired blocks 12. The optoelectronic pair sensor 15 is used to detect whether the drainage tube 5 is separated from the chest drainage port.

[0064] A water level sensor 16 is adhesively fixed in the drainage bottle 6.

[0065] The controller is also provided with a wireless component. The controller is used to send an alarm to the medical staff through the wireless component when the drainage bottle 6 is separated from the drainage tube 5, when the drainage tube 5 is separated from the chest drainage port, and when the detection data of the water level sensor 16 exceeds the preset value.

[0066] The Hall sensor 11 can detect the change of the magnetic field to judge the matching situation of the drainage tube 5 and the drainage bottle 6. When the drainage tube 5 and the drainage bottle 6 are separated, the controller controls the one-way valve 7 to close, thereby truncating the release of the effusion and reducing the amount of effusion spilled outside the drainage bottle 6.

[0067] The wearable monitor 2 consists of two paired blocks 12, which are respectively pasted on both sides of the patient's thoracic drainage orifice. The optoelectronic transmissive sensor 15 can continuously perform transmissive shooting, and judge whether the drainage tube 5 has detached from the thoracic drainage orifice by the change of the optical path, so as to respond in time to the situation of the detachment of the drainage tube 5.

[0068] The water level sensor 16 can judge the loading state of the drainage bottle 6, so as to prompt the medical staff to replace the drainage bottle 6.

[0069] The wireless component can provide remote communication capabilities, so as to remotely send messages to the medical staff, and also facilitate the medical staff to remotely view the information obtained by the controller. When the drainage bottle 6 detaches from the drainage tube 5, the drainage tube 5 detaches from the thoracic drainage orifice, and the detection data of the water level sensor 16 exceeds the preset value, the medical staff are respectively required to go to the patient's place to reconnect the drainage bottle 6 and the drainage tube 5, re-fix the drainage tube 5, and replace the drainage bottle 6.

[0070] Embodiment 6:

[0071] The difference from the above embodiment is that: it further includes a telescopic member 14, the telescopic member 14 is an electric push rod, both ends of the telescopic member 14 are bolt-fixed to the paired block 12, and the controller is used to control the telescopic member 14 to contract after the optoelectronic transmissive sensor 15 detects that the drainage tube 5 has detached from the thoracic drainage orifice, so that the paired block 12 drives the skin on both sides of the thoracic drainage orifice to tighten the thoracic drainage orifice.

[0072] After the drainage tube 5 detaches, the effusion will still be released from the patient's thoracic drainage orifice. At this time, the effusion will not flow into the drainage bottle 6 through the drainage tube 5, but will be directly released onto the hospital bed or into the ward. The telescopic member 14 can contract after detecting the detachment of the drainage tube 5, so as to tighten the thoracic drainage orifice, reduce the release of the effusion, and reduce the pollution of the hospital bed or the ward by the effusion.

[0073] Embodiment 7:

[0074] The difference from the above embodiment is that: the drainage bottle 6 is integrally formed with a pulling rope 17, and a pull ring 18 is adhesively fixed to one end of the pulling rope 17 away from the drainage bottle 6.

[0075] The patient may have needs such as getting out of bed for activities, such as going to the toilet, eating, undergoing temporary examinations, emergency evacuation, etc. The pulling rope 17 and the pull ring 18 can be used by the patient to lift the drainage bottle 6 and keep the drainage bottle 6 in a position below the thoracic drainage orifice.

[0076] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
