Description

Technical Field

[0001] This utility model relates to the field of medical tool technology, specifically to a Bluetooth-enabled early warning device for preventing extubation. Background Technology

[0002] In the field of medical care, ensuring the secure fixation of the drainage tube is crucial for patients who require fluid drainage.

[0003] During drainage, the lack of effective measures to prevent tube removal means that patients may accidentally touch or even pull out the drainage tube due to impaired consciousness, restlessness, or unintentional movements. In some critically ill patients or those recovering post-surgery, accidental removal of the drainage tube can lead to serious consequences such as wound infection, bleeding, and worsening of the condition. This not only increases patient suffering but also places immense workload on medical staff. Traditional nursing methods rely primarily on frequent rounds and manual observation by medical staff to prevent tube removal, which is inefficient and lacks real-time monitoring capabilities. Therefore, we propose a Bluetooth-based early warning device to prevent tube removal. Utility Model Content

[0004] The purpose of this invention is to provide a Bluetooth-based early warning device to prevent unplugging, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a Bluetooth-based early warning device for preventing tube removal, comprising a drainage tube connection assembly and a wrist connection assembly, wherein the drainage tube connection assembly comprises a clamping assembly, a connecting plate and a first Bluetooth module, the connecting plate being fixedly installed on one side of the clamping assembly, and the first Bluetooth module being installed on one side of the connecting plate;

[0006] The wrist connection assembly includes a strap and a mounting shell. The mounting shell is fixedly installed on one side of the strap. A microcontroller, a second Bluetooth module, a signal strength detection module, a wireless transmission module, and an alarm component are installed inside the mounting shell. The second Bluetooth module, the signal strength detection module, the wireless transmission module, and the alarm component are all electrically connected to the microcontroller. The second Bluetooth module is also electrically connected to the signal strength detection module.

[0007] Preferably, a protective cover is fixedly installed on one side of the connecting plate, and the protective cover covers the outside of the first Bluetooth module.

[0008] Preferably, the clamping assembly includes a spring, two arc-shaped clamping plates and two pressing plates, wherein the pressing plates are fixed to the arc-shaped clamping plates, the two pressing plates are rotatably connected, the spring is fixedly connected between the two pressing plates, and the connecting plate is fixedly installed on the outside of one side of the arc-shaped clamping plate.

[0009] Preferably, an anti-slip pad is adhered to the inner side of the arc-shaped clamp, and the anti-slip pad is made of rubber.

[0010] Preferably, a removable cover plate is installed on one side of the mounting housing.

[0011] Preferably, the alarm component includes a vibration motor and a speaker, both of which are electrically connected to the microcontroller, and both are fixedly installed inside the mounting housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This Bluetooth-based anti-extubation warning device uses a microcontroller to set a signal strength threshold. When the signal strength exceeds the threshold, the microcontroller sends an extubation warning signal to medical staff via a wireless transmission module. The microcontroller also controls a vibration motor to generate vibration and emits an alarm sound through a speaker. This alerts the patient and caregiver, preventing accidental extubation due to excessive wrist movement or excessive proximity to the drainage tube, thus greatly improving drainage safety.

[0014] 2. This Bluetooth-enabled anti-removal warning device opens two curved clamps by pressing two pressure plates, allowing the drainage tube to pass between them. Gradually releasing the pressure plates causes the two curved clamps to clamp the outside of the drainage tube under the spring force, thus fixing the curved clamps to the drainage tube. The mounting case is then secured to the wrist with the two free ends fastened with Velcro, making both the strap and the mounting case firmly attached to the wrist. This design is quite convenient to use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a Bluetooth-based early warning device for preventing tube removal, including a drainage tube connection assembly and a wrist connection assembly. The drainage tube connection assembly includes a clamping assembly, a connecting plate 4, and a first Bluetooth module 5. The connecting plate 4 is fixedly installed on one side of the clamping assembly, and the first Bluetooth module 5 is installed on one side of the connecting plate 4. The first Bluetooth module 5 is powered by an independent power supply installed on the surface of the connecting plate 4.

[0023] The wrist connection assembly includes a strap 8 and a mounting shell 9. The mounting shell 9 is fixedly installed on one side of the strap 8. The inner cavity of the mounting shell 9 houses a microcontroller 11, a second Bluetooth module 14, a signal strength detection module 15, a wireless transmission module 16, and an alarm component. The second Bluetooth module 14, the signal strength detection module 15, the wireless transmission module 16, and the alarm component are all electrically connected to the microcontroller 11. The second Bluetooth module 14 is electrically connected to the signal strength detection module 15.

[0024] Specifically, the first Bluetooth module 5 and the second Bluetooth module 14 are wirelessly connected via Bluetooth. The signal strength detection module 15 detects the Bluetooth signal strength of the second Bluetooth module 14 to determine the distance between the first Bluetooth module 5 and the second Bluetooth module 14. If the distance is too small, the microcontroller 11 controls the wireless transmission module 16 to alert medical staff and alerts the patient and caregivers through the vibration motor 12 and the speaker 13, effectively preventing tube removal. An independent power supply is installed in the mounting housing 9 to power the components inside the mounting housing 9.

[0025] Among them, a protective cover 6 is fixedly installed on one side of the connecting plate 4. The protective cover 6 covers the outside of the first Bluetooth module 5 and can protect the first Bluetooth module 5.

[0026] The clamping assembly includes a spring 3, two arc-shaped clamping plates 1, and two pressing plates 2. The pressing plates 2 are fixed to the arc-shaped clamping plates 1 and are rotatably connected to each other. The spring 3 is fixedly connected between the two pressing plates 2. A connecting plate 4 is fixedly installed on the outside of one side of the arc-shaped clamping plate 1. An anti-slip pad 7 made of rubber is adhered to the inside of the arc-shaped clamping plate 1. The spring 3 has a force that pulls the two pressing plates 2 to rotate, causing the two arc-shaped clamping plates 1 to tend to move closer to each other. By pressing one end of the pressing plate 2, the two arc-shaped clamping plates 1 are opened and moved to the outside of the drainage tube. The pressing plates 2 are gradually released, and the two arc-shaped clamping plates 1 clamp the drainage tube. The anti-slip pad 7 can increase the friction with the outside of the drainage tube, so that the entire clamping assembly is clamped on the outside of the drainage tube.

[0027] Among them, a removable cover plate 10 is installed on one side of the mounting housing 9. The cover plate 10 is placed on one side of the mounting housing 9 to protect the components inside the mounting housing 9.

[0028] The alarm component includes a vibration motor 12 and a speaker 13. Both the vibration motor 12 and the speaker 13 are electrically connected to the microcontroller 11. Both the vibration motor 12 and the speaker 13 are fixedly installed in the inner cavity of the mounting housing 9. After receiving the signal strength data, the microcontroller 11 compares it with the threshold. If the signal strength exceeds the threshold, an alarm is triggered by the vibration motor 12 and the speaker 13.

[0029] Working principle: This utility model is a Bluetooth-based early warning device for preventing tube removal. By pressing the two pressing plates 2, the two arc-shaped clamps 1 are opened, and the drainage tube is passed between the two arc-shaped clamps 1. Then, the pressing plates 2 are gradually released. Under the elastic force of the spring 3, the two arc-shaped clamps 1 are clamped on the outside of the drainage tube, thereby fixing the arc-shaped clamps 1 and the drainage tube. At the same time, the protective cover 6 emits a Bluetooth signal.

[0030] Simultaneously, one or two straps 8 are fastened to one or both wrists of the patient. A Bluetooth connection is established between the second Bluetooth module 14 and the first Bluetooth module 5. The signal strength detection module 15 detects the signal strength received by the second Bluetooth module 14 in real time and transmits the signal strength value to the microcontroller 11. The farther the distance between the second Bluetooth module 14 and the first Bluetooth module 5, the weaker the signal strength; the closer the distance between the second Bluetooth module 14 and the first Bluetooth module 5, the stronger the signal strength. Therefore, the microcontroller 11 sets a signal strength threshold. When the signal strength exceeds the threshold, the microcontroller 11 sends a tube removal warning signal to medical staff through the wireless transmission module 16. The microcontroller 11 also controls the vibration motor 12 to vibrate and emits an alarm sound through the speaker 13. This can alert the patient and caregiver, preventing accidental removal of the tube due to excessive wrist movement or excessive proximity to the drainage tube, thus greatly improving the safety of drainage.
