Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an anti-extubation auxiliary device. Background Technology

[0002] In clinical practice, it is common for patients to remove intubation themselves due to loss of consciousness or discomfort while having indwelling gastric tubes, central venous catheters, PICC lines, or endotracheal intubations. This not only may lead to treatment interruption and complications, but also increases medical risks and costs. Currently, existing technologies to prevent patients from removing intubation themselves mainly involve the following two approaches and problems:

[0003] The first approach involves strengthening the connection between the tube and the body and installing an alarm device. This method typically uses high-strength straps to securely fasten the tube to the patient's body, while a displacement sensor monitors the tube's status. An alarm is triggered when the patient pulls on the tube. For example, Chinese patent application number 202220232541.7 discloses a gastric tube dislodgement alarm device. However, if this method is loose, the patient can easily pull out the tube; if it is too tight, it will cause severe discomfort, and prolonged pressure can lead to skin damage, poor blood circulation, and other problems. This discomfort may also make the patient more inclined to pull out the tube. Furthermore, the alarm device's triggering mechanism relies on the tube being subjected to a certain degree of tension or displacement. This means that when the alarm is triggered, the tube is often partially or even completely detached from the body, significantly reducing its effectiveness in preventing tube dislodgement.

[0004] The second approach is to use restraint straps to immobilize the patient's hand, restricting their range of motion and thus reducing the likelihood of extubation. However, most existing restraint straps lack effective alarm mechanisms, failing to promptly alert medical staff whether the patient's hand has broken free. A restraint glove disclosed in Chinese patent application number 201921411550.7 has an alarm mechanism, but even when the alarm occurs, it cannot directly prove that the patient's hand has broken free and that extubation was performed afterward. False alarms may occur where the patient's hand has broken free but the tube has not been removed, making it difficult for medical staff to quickly and accurately assess the actual risk, reducing nursing efficiency, and failing to effectively ensure tube safety. Summary of the Invention

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. It should also be noted that the terminology used in this invention is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0023] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the protection scope of the present invention.

[0024] Example 1:

[0025] The anti-pulling auxiliary device provided in Embodiment 1 of the present invention, such as Figures 1 to 4 As shown, the device includes a restraint glove 1 that can cover the patient's hand, a connecting rope 2, a tension sensor 3, a fixing strap 4, and a control terminal 5. The connecting rope 2 can connect the restraint glove 1 to a stable support. The tension sensor 3 is mounted on the connecting rope 2. The fixing strap 4 includes a trachea fixing mechanism 41 and a connection strength adjustment mechanism 42. The trachea fixing mechanism 41 is fixed on the connection strength adjustment mechanism 42. The connection strength adjustment mechanism 42 is communicatively connected to the control terminal 5. The tension sensor 3 is also communicatively connected to the control terminal 5.

[0026] In the anti-extraction auxiliary device provided in Embodiment 1 of this invention, when in operation, the patient wears a restraint glove 1, and a connecting rope 2 connects the restraint glove 1 to a stable support, restricting the range of hand movement. When the patient attempts to break free of the restraint glove 1 and pull the connecting rope 2, the tension sensor 3 senses the change in tension of the connecting rope 2 in real time and transmits the signal to the control terminal 5. The tracheal fixation mechanism 41 of the fixing strap 4 is responsible for fixing the medical tubing. The connection strength adjustment mechanism 42 can, under the command of the control terminal 5, drive the adjustment buckle to adjust the tightness of the fixing strap 4 (the connection strength adjustment mechanism 42 is a mechanism for automatically adjusting the tightness of the fixing strap 4 to the human body, and devices that automatically adjust the tightness of the fixing strap 4 to the human body are existing technologies, such as the automatic wearable head-mounted display device disclosed in Chinese Patent Application No. 201910820848.1). The tracheal fixation mechanism 41 is used to fix the medical tubing. The tracheal fixation mechanism 41 adjusts the tightness of the medical tubing according to the tightness of the fixing strap 4 relative to the human body. The connection strength between the tube and the human body is controlled by a preset threshold in the control terminal 5. After receiving the signal from the tension sensor 3, the control terminal 5 compares and analyzes it with the preset threshold. When the patient's hand moves towards the medical tube, the tension of the connecting rope 2 triggers a change in the value of the tension sensor 3. Based on the analysis results, the control terminal adjusts the connection strength adjustment mechanism 42 in real time to adjust the tightness of the fixing strap 4. The distance between the patient's hand and the medical tube is determined by the signal from the tension sensor 3. When the patient's hand is closer to the medical tube, the restraint of the fixing strap 4 will automatically increase; conversely, if the patient's hand is away from the medical tube, the restraint will be weakened accordingly. By dynamically adjusting the restraint strength, resistance can be increased when the patient attempts to remove the tube, and discomfort can be reduced when the patient's hand is away from the tube, achieving a balance between safety and comfort. When the signal feedback from the tension sensor 3 reaches the threshold where the patient's hand can easily contact the medical tube, the control terminal 5 alerts medical staff, who can then promptly check the patient's condition. Compared to existing technologies that simply use a restraint strap to fix the hand with a tension sensor directly mounted on the strap, this embodiment incorporates a connection strength adjustment mechanism 42 to adjust the connection strength between the restraint strap 4 and the patient. On one hand, a higher connection strength between the restraint strap 4 and the patient results in greater discomfort for the patient, making it more difficult for them to pull out the medical tube, thus preventing the risk of accidental removal. On the other hand, a higher connection strength also makes it more difficult for the patient to remove the medical tube, requiring more time and allowing medical staff more time to intervene. Compared to existing technologies that simply increase the connection strength of the restraint strap 4 to prevent the patient from pulling out the medical tube, this embodiment reduces the restraint of the restraint strap 4 when the patient's hand is away from the medical tube, allowing for greater comfort in a normal state.

[0027] The anti-extubation auxiliary device provided in this embodiment solves the problem in the prior art of monitoring patients' accidental tube removal. When the alarm device is triggered, the tube is often partially or even completely removed from the body. Simply using a restraint strap to fix the hand will trigger an alarm if the hand moves, which may result in false alarms. This device can better monitor and manage patients' unconscious tube removal behavior.

[0028] As a preferred embodiment, in this example, the restraint glove 1 includes a glove body 11 with an opening; the glove body 11 has a receiving cavity 111 communicating with the opening; a fastening component 112 for tightening the opening is provided at the opening; and the glove body 11 is fixed to one end of the connecting rope 2. Since the patient needs to use the coordination of their fingers and palm to grasp the medical tube when pulling it out, this embodiment preferably uses a restraint glove 1 structure. Due to the action of the fastening component 112, the patient's hand is restricted from extending out of the receiving cavity 111; when the patient directly grasps the medical tube while wearing the glove body 11, it is difficult to perform a grasping action.

[0029] If a wired connection is used, the length and location of the cable will restrict the patient's range of motion and increase the risk of cable tangling and damage. In this embodiment, a first wireless signal transmission component 21 is fixed to the connecting rope 2; the first wireless signal transmission component 21 is electrically connected to the tension sensor 3; a wireless signal processing component 51 is provided in the control terminal 5; the wireless signal processing component 51 is communicatively connected to the first wireless signal transmission component 21. By using the first wireless signal transmission component 21 and the wireless signal processing component 51, this embodiment allows the patient to be free from the constraints of the cable. After wearing the restraint glove 1 and connecting the connecting rope 2, the patient can move relatively freely within a certain range without feeling discomfort due to cable pulling, which also reduces the possibility of device malfunction due to cable problems, improves the patient's user experience and the stability of the device; in this embodiment, a Wi-Fi module is preferably used for wireless signal transmission.

[0030] The device provided in this embodiment of the invention primarily uses the patient's hand movement to change the connection strength between the medical tubing and the patient, thereby reducing the likelihood of accidental removal of various medical tubing, such as gastric tubes, central venous catheters, and endotracheal tubes. This embodiment uses an endotracheal tube as an example to illustrate the fixation of the medical tubing. As a preferred embodiment, the endotracheal fixation mechanism 41 includes an endotracheal fixation strap 411 and an adjustment buckle 412; the connection strength adjustment mechanism 42 includes a motor 421, an output wheel 422, and a control module 423; the endotracheal fixation strap 411 can fix the medical tubing; the endotracheal fixation strap 411... 11 is strip-shaped; both ends of the trachea fixing strap 411 are fixed through the adjusting buckle 412; the housing of the motor 421 is fixed on the adjusting buckle 412; the output wheel 422 is fixed on the output shaft of the motor 421; the end of the trachea fixing strap 411 is fixed on the output wheel 422; when the output wheel 422 rotates, the trachea fixing strap 411 can be wound around the output wheel; the motor 421 is electrically connected to the control module 423; the control module 423 is equipped with a second wireless signal transmission component 4231; the second wireless signal transmission component 4231 is communicatively connected to the wireless signal processing component 51. When it is necessary to adjust the tightness of the connection between the medical tube and the patient, the connection strength adjustment mechanism 42 is used to control the position of the trachea fixation mechanism 41, thereby achieving the state of the medical tube relative to the patient. In specific operation, the wireless signal processing component 51 sends a command, the second wireless signal transmission component 4231 receives the command, and the control module 423 controls the motor 421 to work, thereby driving the output wheel 422 to rotate. (In this preferred embodiment, one end of the trachea fixation strap 411 is fixed to the adjustment buckle 412, and the other end is fixed to the output wheel 422. The housing of the motor 421 is fixed to the adjustment buckle 412 to limit the electric current.) The motor 421 and the adjusting buckle 412 are fixed relative to each other. When the output shaft of the motor 421 rotates, the output shaft moves relative to the adjusting buckle 412 because the adjusting buckle 412 is fixed on the housing of the motor 421. The rotation of the output shaft of the motor 421 drives the output wheel 422 to rotate, which can change the position of the adjusting buckle 412 relative to the end of the tracheal fixation strap. This changes the distance between the end of the tracheal fixation strap 411 and the adjusting buckle 412. The position of the adjusting buckle 412 is stationary relative to the patient. The tracheal fixation strap 411 is fixed around the patient. The farther the end of the tracheal fixation strap 411 extends to the adjusting buckle 412, the smaller the loop formed by the tracheal fixation strap 411 will be, thus achieving a stronger restraint on the patient.

[0031] The detachment of medical tubing from the patient is not limited to the tracheal fixation strap 411 detaching along with the tracheal fixation tubing; it can also occur when a separate medical tubing detaches from the tracheal fixation strap 411. In this embodiment, the tracheal fixation mechanism 41 also includes a laser displacement sensor 413 (the laser displacement sensor 413 is existing technology, such as a TOF-based laser displacement sensor; the specific structure of the laser displacement sensor will not be described in detail here); the tracheal fixation strap 411 has a tubing fixation hole 4111; the laser displacement sensor 413 is fixed to the inner wall of the tubing fixation hole 4111; the laser displacement sensor 413 can emit a laser beam to irradiate the surface of the medical tubing within the tubing fixation hole 4111 and receive the reflected light signal to calculate the displacement of the medical tubing; the laser displacement sensor 413 is electrically connected to the control module 423. The laser displacement sensor 413 detects the displacement of the medical pipeline relative to the pipeline fixing hole 4111 and feeds the signal back to the control module 423, which in turn feeds it back to the control terminal 5, allowing medical staff to remotely monitor the status of the medical pipeline through the control terminal 5.

[0032] In this embodiment, the anti-extubation auxiliary device is equipped with a first buzzer 6 and a second buzzer 7, both of which are electrically connected to the control terminal 5. (Preferredly, in this embodiment, the first buzzer is triggered when the tension sensor detects a tension value exceeding 50% of the safety threshold; the second buzzer is triggered when the laser displacement sensor detects a pipe displacement exceeding 2cm.) This dual-buzzer coordinated alarm mechanism achieves accurate early warning of the patient's condition through differentiated sound feedback. When the tension sensor 3 detects a tension signal generated by the patient's hand movement, it is transmitted via the first wireless signal transmission component 21 to the wireless signal processing component 51 within the control terminal 5. After intelligent analysis, if the system determines that the patient's hand movement may touch the medical tube, it will automatically activate the first buzzer 6 to emit an alarm sound of a specific frequency or timbre. This warning signal aims to alert medical staff that the patient has a potential tendency to extubate, so that intervention measures can be taken in advance. Medical staff can flexibly arrange patrol times according to the actual situation; when the laser displacement sensor 413 detects that the displacement distance of the medical pipe in the pipe fixing hole 4111 exceeds the preset safety threshold, the signal will be quickly transmitted to the wireless signal processing component 51 of the control terminal 5 through the second wireless signal transmission component 4231 in the control module 423; then, the second buzzer 7 will emit a high-intensity, high-frequency alarm sound different from the first buzzer 6, clearly indicating that the medical pipe has abnormally shifted and is in a high-risk state, requiring medical staff to respond immediately and go to the scene to handle it, thereby effectively avoiding medical risks caused by pipe detachment; through this hierarchical alarm mode, the accuracy and timeliness of nursing response are significantly improved, and the allocation efficiency of medical resources is optimized.

[0033] In this embodiment, a pressure sensor 8 is also included. The pressure sensor 8 is disposed in the area where the fixing strap 4 contacts the patient's skin. The pressure sensor 8 is electrically connected to the control terminal 5. Traditional fixing straps often struggle to accurately control the tightness of medical tubing when fixing it. If the strap is too tight, it can cause severe discomfort to the patient and may lead to skin damage and poor blood circulation over time. If the strap is too loose, it cannot effectively fix the tubing and there is a risk of the tubing falling off. In this embodiment, to facilitate the adjustment of the position of the restraint glove 1 and the medical tubing, the fixing strap 4 is designed to have the ability to automatically and remotely adjust its tightness. Therefore, this embodiment requires a pressure sensor 8 to monitor the pressure applied by the fixing strap 4 to the patient's skin in real time and transmit the pressure data to the control terminal 5. The control terminal 5 can determine whether the current pressure of the fixing strap 4 is appropriate based on a preset pressure range. If the pressure is too high, the control terminal 5 can send a command to the connection strength adjustment mechanism 42 to appropriately loosen the fixing strap 4, thereby adapting to different patients and preventing the patient from experiencing excessive discomfort due to the fixing strap 4 being too tight.

[0034] In this embodiment, the glove body 11 has multiple ventilation holes 113; the ventilation holes 113 are evenly distributed on the back of the hand and fingers of the glove body 11; a waterproof and breathable membrane is provided inside the ventilation holes 113. The setting of ventilation holes 113 on the glove body 11 is prior art, such as the restraint glove for preventing tube pull-out disclosed in Chinese Patent Application No. 202420146342.3. In this embodiment, in order to avoid the patient's hands from feeling stuffy and damp due to sweat when wearing the glove body 11 for a long time, causing discomfort to the patient and affecting the health of the hand skin, by setting ventilation holes 113 and making the ventilation holes 113 evenly distributed, air can circulate inside the glove, and with the help of the waterproof and breathable membrane, the sweat and heat generated by the patient's hands can be effectively discharged, keeping the hands dry and comfortable. This helps to reduce the patient's irritability caused by wearing gloves and improve the patient's acceptance and compliance with the anti-tube pull-out auxiliary device.

[0035] In summary, this invention provides an anti-extubation auxiliary device, relating to the field of medical devices, comprising a restraint glove that covers the patient's hand, a connecting rope, a tension sensor, a fixing strap, and a control terminal. The connecting rope connects the restraint glove to a stable support. The tension sensor is mounted on the connecting rope. The fixing strap includes a trachea fixing mechanism and a connection strength adjustment mechanism. The trachea fixing mechanism is fixed to the connection strength adjustment mechanism. The connection strength adjustment mechanism is communicatively connected to the control terminal. The tension sensor is also communicatively connected to the control terminal. The anti-extubation auxiliary device provided by this invention solves the problem in existing technologies where, when an alarm is triggered, the tube has often been partially or completely removed from the body. Furthermore, simply using a restraint strap to fix the hand can trigger an alarm based on hand movement, leading to false alarms. This invention allows for better monitoring and management of unintentional tube removal by patients.
