Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a responsive closed system of a smart dressing. Background Art

[0002] Accidental tube removal (disengagement) refers to an accidental detachment of the catheter, the patient's self-extubation without the medical staff's consent, or improper operation by the medical staff that results in an extubation event. In the field of medical devices, various types of tubes such as closed chest drainage tubes and abdominal tubes play a key role in clinical treatment, but their accidental detachment may cause a series of serious complications, including bleeding, infection, air entering the chest cavity (such as pneumothorax), leakage of contents, etc., which directly endanger the patient's life safety. These complications will not only prolong the patient's hospitalization time and increase medical expenses, but also cause physical and mental pain to the patient. In addition, the process of re-catheterization will further aggravate the patient's pain and financial burden, and improper handling may even lead to medical disputes.

[0003] Currently, there is a lack of a smart dressing that can automatically identify and instantly seal wounds after a tube has fallen off.

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0044] Example 1

[0045] See also Figures 1 to 8 This embodiment provides a responsive closed system for a smart dressing, comprising: a dressing patch 1, a first shell 2, a monitoring component 3, an extrusion component 4, and an alarm component 5, wherein:

[0046] The first shell 2 is fixedly bonded to the dressing patch 1 and has an open bottom;

[0047] The monitoring component 3 is located in the first housing 2 and is used to monitor whether the pipeline is falling off;

[0048] The extrusion component 4 is located in the first housing 2 and presses the location where the pipe is detached after the monitoring component 3 detects that the pipe is detached;

[0049] The alarm component 5 issues an alarm after the monitoring component 3 detects that the pipeline is detached.

[0050] In this embodiment, a notch 101 is provided in the middle of one side of the dressing patch 1 for wrapping and fixing the pipe;

[0051] The monitoring assembly 3 includes a support block 301, a movable rod 302, a movable plate 303, a fixed seat 306, an electromagnet 308 and a battery 6. The support block 301 and the fixed seat 306 are fixed to the inner wall of the first shell 2 on the side close to the notch 101, and the fixed seat 306 is above the support block 301. The upper end of the movable rod 302 passes through the support block 301 and is connected to the limit block 304, and the movable plate 303 is connected to the bottom of the movable rod 302. There is a first positive conductive block 305 on the top of the limit block 304, and a second positive conductive block 307 on the bottom of the fixed seat 306. The negative power conductive sheet 602 of the battery 6 is connected to the negative pole of the electromagnet 308 via a first wire, and the positive power conductive sheet 601 is connected to the first positive conductive block 305 via a second wire;

[0052] The extrusion assembly 4 includes a pressure plate 401 and a permanent magnet 402. The permanent magnet 402 is embedded in the top of the pressure plate 401, and the pressure plate 401 moves within the first shell 2. Support rods 403 are provided on both sides of the protrusion 201 at the top of the first shell 2. Sliders 404 are mounted on the support rods 403. The slides 404 are hinged to the upper end of the pressure plate 401 via connecting rods 406. A second spring 405 is sleeved on the support rod 403, with the ends of the spring resting against the slide 404 and the inner wall of the first shell 2, respectively. The electromagnet 308 is mounted on the bottom of the protrusion 201. A guide sleeve 408 is provided at the top of the first shell 2. A guide rod 407 is provided on the pressure plate 401, and the upper end of the guide rod 407 is inserted into the guide sleeve 408. The electromagnet 308 is located above the permanent magnet 402.

[0053] Under normal use, the pipe is fixed through the notch 101 of the dressing patch 1, and the pipe will generate an upward squeezing force on the movable plate 303. This squeezing force pushes the movable rod 302 to move upward, so that the first positive conductive block 305 on the limit block 304 contacts and electrically connects with the second positive conductive block 307 at the bottom of the fixing seat 306. At this time, the current of the battery 6 forms a path through the first wire, the electromagnet 308, the second wire, the first positive conductive block 305, and the second positive conductive block 307, and the electromagnet 308 is energized to generate magnetic force. Since the electromagnet 308 is located above the permanent magnet block 402, the magnetic force generated will attract the permanent magnet block 402 upward, thereby driving the pressure plate 401 to move upward, so that the pressure plate 401 and the dressing patch 1 remain separated and do not cause additional pressure on the wound.

[0054] When the pipe falls off accidentally, the movable plate 303 is no longer subject to the squeezing force of the pipe and moves downward under the action of its own gravity. This disconnects the first positive conductive block 305 from the second positive conductive block 307, and the circuit of the electromagnet 308 is cut off, and the electromagnet 308 loses its magnetism. At this time, the elastic force of the second spring 405, which was originally overcome by the magnetic force of the electromagnet 308, begins to play a role, and the second spring 405 pushes the slider 404 to slide along the support rod 403 toward the dressing patch 1. The slider 404 drives the pressure plate 401 to move downward through the connecting rod 406, and the guide rod 407 on the pressure plate 401 slides in the guide sleeve 408 to ensure that the pressure plate 401 descends vertically, accurately pressing the position where the pipe falls off, and achieving wound closure and pressurized hemostasis.

[0055] Furthermore, a first spring 309 is sleeved on the movable rod 302 , the bottom of the first spring 309 presses on the movable plate 303 , and the top rests on the bottom of the support block 301 .

[0056] First spring 309 assists in the entire operation. When the pipe squeezes movable plate 303, causing movable rod 302 to move upward, first spring 309 is compressed, storing elastic potential energy. When the pipe falls off, movable plate 303 loses its compressive force, and first spring 309 begins to release this stored elastic potential energy. This elastic force pushes movable plate 303 and movable rod 302 downward more quickly, allowing the first positive conductive block 305 and second positive conductive block 307 to disconnect more quickly, thereby causing electromagnet 308 to lose its magnetism more quickly.

[0057] In this embodiment, the alarm assembly 5 includes a second housing 501, which houses a buzzer 502. The battery 6 is also located within the second housing 501. The second housing 501 is fixed to the first housing 2. The negative terminal of the buzzer 502 is connected to the negative power supply conductive sheet 602 of the battery 6 via a third wire.

[0058] One of the sliders 404 is connected to an insulating sliding seat 503, and a strip-shaped sliding hole 506 is provided at the bottom of the second shell 501. The upper end of the insulating sliding seat 503 slides into the second shell 501 through the strip-shaped sliding hole 506 and is connected to a conductive plate 504. The positive conductive plate 601 of the power supply is electrically connected to the positive conductive plate 5021 of the buzzer 502 through the conductive plate 504.

[0059] When the pipe falls off, the extrusion assembly 4 begins to operate, and the slider 404 slides along the support rod 403 under the action of the second spring 405. Because one of the sliders 404 is connected to an insulating sliding seat 503, the movement of the slider 404 causes the insulating sliding seat 503 to move along with it. The insulating sliding seat 503 slides within the strip-shaped sliding hole 506 at the bottom of the second housing 501. When the slider 404 moves to a certain position, the conductive plate 504 on the insulating sliding seat 503 connects the positive conductive plate 601 of the power supply to the positive conductive plate 5021 of the buzzer 502. At this point, the battery 6, the third wire, the buzzer 502, and the conductive plate 504 form a complete circuit path, and the buzzer 502 is powered on and begins to operate, emitting an alarm. In this way, the displacement of the slider 404 during the operation of the extrusion assembly 4 is used to trigger the alarm assembly 5, realizing an automatic alarm function after the pipe falls off, promptly alerting medical staff or surrounding personnel to the patient's abnormal condition.

[0060] Furthermore, a sound hole 505 is provided in the second housing 501. When the buzzer 502 sounds an alarm, the sound propagates within the second housing 501. The sound hole 505 provides a channel for the sound to propagate from the interior of the second housing 501 to the external environment. This allows the alarm to travel farther and more clearly, ensuring that medical staff and surrounding personnel can hear the alarm more promptly and accurately, allowing them to respond quickly and provide appropriate treatment to the patient.

[0061] In this embodiment, the dressing patch 1 includes a non-woven fabric layer 1001 and a bacterial cellulose membrane 1002. The bacterial cellulose membrane 1002 is fixed to the bottom of the non-woven fabric layer 1001. The thickness of the non-woven fabric layer 1001 is 0.2 mm to 0.5 mm, and the thickness of the bacterial cellulose membrane 1002 is 1 mm to 3 mm.

[0062] The non-woven fabric layer 1001 has good air permeability and a certain degree of mechanical strength. This air permeability ensures that the skin around the wound can breathe normally, preventing discomfort or increased risk of infection caused by prolonged exposure to a closed environment. Its mechanical strength also provides support for the entire dressing patch 1, maintaining its shape and resisting deformation during use, ensuring that other components can function properly.

[0063] Bacterial cellulose membrane 1002 has excellent biocompatibility and can adhere well to human tissue, reducing irritation to wounds. At the same time, it has a high porosity and surface area, which makes it highly capable of absorbing exudate. During the wound healing process, some exudate is produced, and bacterial cellulose membrane 1002 can quickly absorb this exudate, keeping the wound surface dry and clean. In addition, bacterial cellulose membrane 1002 also has certain antibacterial properties, which can inhibit the growth and reproduction of bacteria on the wound surface, reducing the risk of infection, creating a favorable environment for wound healing, and promoting faster wound healing.

[0064] In this embodiment, at least one of chitosan, γ-polyglutamic acid, and β-glucan is added to the bacterial cellulose membrane 1002. The antibacterial properties of chitosan, γ-polyglutamic acid, and β-glucan on bacteria are more conducive to wound healing.

[0065] Furthermore, an adhesive layer 1003 is provided at the bottom of the bacterial cellulose membrane 1002 , and the adhesive layer 1003 is distributed in a ring shape at the bottom edge of the bacterial cellulose membrane 1002 .

[0066] The main function of the adhesive layer 1003 is to firmly adhere the dressing patch 1 to the patient's skin. The design of the annular distribution at the bottom edge of the bacterial cellulose membrane 1002 can form a relatively closed environment while ensuring that the dressing patch 1 fits tightly against the skin. This closed environment can effectively prevent external pollutants such as bacteria and dust from contacting the wound, reducing the risk of wound infection. At the same time, the viscosity of the adhesive layer 1003 ensures that the dressing patch 1 will not be easily displaced or fall off during use, ensuring the positional stability of the monitoring component 3, the extrusion component 4 and the alarm component 5, so that they can accurately monitor and respond to the pipeline status. During the patient's activities, even if the body posture changes, the adhesive layer 1003 can keep the dressing patch 1 in the correct position at all times, continue to play a protective and therapeutic role on the wound, and improve the reliability and safety of the use of the smart dressing.

[0067] Working principle:

[0068] Under normal conditions, the pipe wrapped and fixed by the dressing patch 1 will press the movable plate 303 upward, so that the first positive conductive block 305 is electrically connected to the second positive conductive block 307, and then the electromagnet 308 is energized to generate magnetic force, which attracts the permanent magnet block 402 upward, and the pressure plate 401 does not contact the dressing patch 1.

[0069] Abnormal Response: Once the tube falls off, movable plate 303 is no longer squeezed, the first and second positive conductive blocks 305 and 307 are disconnected, and electromagnet 308 loses its magnetism. The permanent magnet block 402 and pressure plate 401 descend under the action of the second spring 405, pressing the tube off to stop bleeding. Simultaneously, alarm component 5 activates, and buzzer 502 sounds an alarm to alert medical staff and nearby personnel.
