Description

Technical Field

[0001] The utility model belongs to the field of medical supplies, and in particular relates to a wrist band used for monitoring unplanned extubation in clinical medical applications. Background Art

[0002] Due to the critical condition and poor general condition of ICU patients, most patients will have various types of feeding tubes or drainage tubes placed in them to facilitate treatment and nutritional supply. The ICU is a department with a high incidence of unplanned extubation of patients. Some patients may also engage in self-harm or other-harming behaviors due to unclear consciousness. In order to prevent the occurrence of unplanned extubation, self-harm, and other-harming behaviors, patients need to be protectively restrained.

[0003] Clinical studies have found that the restraint devices currently used are mostly restraint belts or restraint hand clasps. Restraint belts are used to forcibly restrain patients. Forced restricted movements can cause patients to feel anxious, depressed, fearful, and helpless, affecting their emotional state and recovery process. At the same time, patients may suffer from skin injuries, pressure sores, or muscle atrophy due to being in a fixed position for a long time. In addition, ICU patients may experience emergencies at any time and may need first aid or emergency treatment at any time. The use of restraint belts limits rescue or emergency treatment.

[0004] Compared with the restraint belt, the restraint of hand clapping has a certain degree of improved freedom, but it still restrains the patient's hands including fingers. Long-term restraint can lead to joint stiffness and hand dysfunction. At the same time, hand restrictions can make intravenous cannulation, blood sampling, drug injection and other operations difficult, delaying and affecting the treatment process.

[0005] Based on the above reasons, there is an urgent need for an improved hand restriction device for unplanned extubation to avoid excessive restriction of hand freedom and to humanely manage the patient's own abnormal extubation. Utility Model Content

[0006] Aiming at the problem that restraint devices such as restraint belts or restraint hand claps for restraining abnormal extubation of patients in clinical practice are too restrictive, the utility model provides a wrist band for monitoring unplanned extubation.

[0007] In order to solve the above technical problems, the utility model provides a wrist band for monitoring unplanned extubation, including a wrist band body, on which a monitoring device is movably and detachably connected, the monitoring device including a shell, in which at least a tilt sensor, an embedded microprocessor and a power supply system are arranged, the embedded microprocessor including a processor unit, a memory unit, an input interface and an output interface, the output signal of the tilt sensor is connected to the input interface of the embedded microprocessor through a circuit, the embedded microprocessor transmits an alarm signal to the alarm device through the output interface, and the power output of the power supply system is connected to the embedded microprocessor and the tilt sensor through a circuit.

[0008] Preferably, the wrist band body is made of disposable material, and the wrist band body is a flat and long structure in the unfolded state.

[0009] Preferably, a connecting ring is provided at the bottom of the shell, and the wrist strap body passes through the connecting ring.

[0010] Preferably, a first adhesive sheet is provided on the outer side of the wrist band body, the shell is connected to the second adhesive sheet, the first adhesive sheet and the second adhesive sheet are adhered to each other, so that the shell is adhered to the outer side of the wrist band body.

[0011] Preferably, the alarm device is integrated with the monitoring device and is disposed inside the housing.

[0012] Preferably, the alarm device is separately arranged from the monitoring device, the alarm device includes a Bluetooth or Wi-Fi receiver, a display screen, an alarm and a start-stop switch, the monitoring device includes a wireless communication module and an alarm trigger, the wireless communication module is a Bluetooth module or a Wi-Fi module, the alarm signal generated by the alarm trigger is transmitted to the Bluetooth or Wi-Fi receiver of the alarm device through the wireless communication module, and triggers the alarm to sound an alarm and / or flash a light, and the start-stop switch is used to start or stop the alarm device.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the wrist strap of the utility model can monitor the angle of the patient's wrist based on the effect of gravity, and then judge the angle of the patient's hand lifting, and give an alarm signal according to the preset threshold value whether the patient has the risk of pre-lifting the hand for extubation. The alarm signal is transmitted to the alarm device to realize the alarm, and then attract the attention of medical staff or nursing staff or family members, and then through caring and scientific treatment of the patient, the patient can actively accept the risk of abnormal extubation. The utility model fundamentally solves the problem of restraining the patient's abnormal extubation behavior by forcibly restricting the patient's personal freedom. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figures 1 to 3As shown, a wristband for monitoring unplanned extubation includes a wristband body 1, on which a monitoring device 2 is movably and detachably connected, and the monitoring device 2 includes a housing 201, in which at least a tilt sensor 202, an embedded microprocessor 203 and a power supply system 204 are arranged, and the embedded microprocessor 203 includes a processor unit 205, a memory unit 206, an input interface 207 and an output interface 208, and the output signal of the tilt sensor 202 is connected to the input interface 207 of the embedded microprocessor 203 through a circuit, and the embedded microprocessor 203 transmits an alarm signal to the alarm device 3 through the output interface 208, and the alarm device 3 is integrally arranged with the monitoring device 2 and arranged in the housing 201. The power output of the power supply system 204 is connected to the embedded microprocessor 203 and the tilt sensor 202 through a circuit. The wristband of this embodiment can monitor the angle of the patient's wrist based on the effect of gravity, and then determine the angle of the patient's hand lifting. According to the preset threshold, an alarm signal is given to indicate whether the patient is at risk of extubation due to pre-lifting the hand. The alarm signal is transmitted to the alarm device to realize an alarm, thereby attracting the attention of medical staff or nursing staff or family members, and then by providing caring and scientific treatment to the patient, the patient can actively accept the risk of abnormal extubation. The utility model fundamentally solves the problem of restraining the patient's abnormal extubation behavior by forcibly restricting the patient's personal freedom.

[0021] In other specific embodiments, the wristband body 1 is made of disposable materials, and the unfolded state of the wristband body 1 is a flat and long structure; the wristband body 1 is used as a carrier of the monitoring device 2 and is in direct contact with the patient. ICU critically ill patients generally have intubation incisions, and disinfection and sterilization work is more important. Traditional wristbands are shared by multiple patients, which is easy to cause cross infection. The disposable material wristband of this embodiment can avoid this situation. Each patient can use a new wristband, which effectively reduces the risk of infection and the workload of medical staff for cleaning and maintenance, thereby improving work efficiency. Critically ill patients are in a coma and naturally relaxed state for a long time, and their wrists are also in a state of low blood flow for a long time. Therefore, they are more sensitive to wrist restraints, and are prone to poor blood flow and a series of peripheral necrosis cases. This embodiment adopts a flat and long structure wristband design, so that the barrier between the patient's wrist and the carrier is thinner, reducing the pressure on the patient's wrist and improving wearing comfort. The wrist band body 1 and the monitoring device 2 of this embodiment are a split connection structure. Specifically, a connecting ring 4 is provided at the bottom of the shell, and the wrist band body 1 passes through the connecting ring 4. Since the wrist band body 1 is a disposable structure, this structure facilitates the rapid connection and separation of the monitoring device 2 and the wrist band body 1, and is also convenient for adjusting the relative position of the monitoring device 2 and the wrist band body 1, thereby improving the wearing comfort of the patient.

[0022] In other specific embodiments, a first adhesive sheet is provided on the outer side of the wrist band body 1, the shell is connected to a second adhesive sheet, the first adhesive sheet and the second adhesive sheet are adhered to each other, and the shell is adhered to the outer side of the wrist band body. This embodiment can accurately and firmly fix the relative position of the monitoring device, such as fixing the monitoring device above the wrist to prevent it from rotating relative to the wrist band body, making the monitoring signal more eye-catching, and at the same time preventing the monitoring device from rotating to the bottom of the wrist band to cause discomfort to the patient.

[0023] In other specific embodiments, Figure 3 As shown, the alarm device 3 is separately arranged from the monitoring device 2, and the alarm device 3 includes a Bluetooth 301 or Wi-Fi receiver, a display screen 303, an alarm 304 and a start-stop switch 302. The monitoring device 2 includes a wireless communication module 209 and an alarm trigger 210. The wireless communication module 209 is a Bluetooth module or a Wi-Fi module. The alarm signal generated by the alarm trigger 210 is transmitted to the Bluetooth 301 or Wi-Fi receiver of the alarm device 2 through the wireless communication module 209, and triggers the alarm 304 to sound an alarm and / or flash light. The start-stop switch 302 is used to start or stop the alarm device 3. The alarm device 3 can be set on the body of the nursing staff or on the office or on the patient's bed. On the one hand, it avoids the alarm device 3 being directly set on the patient's wrist, reduces the weight on the wrist, and improves the wearing comfort of the wrist watch; on the other hand, the alarm device 3 is carried by the nursing staff. Once the alarm signal is triggered, the nursing staff will receive and feel the alarm signal in real time, which is convenient for caring treatment in the first time. In addition, the alarm device 3 can also be set in a more conspicuous position such as an office or a bed, which is suitable for the situation where multiple people are caring for a patient in one bed, and has better applicability.

[0024] The present invention is not limited to the embodiments discussed above. The above description of the specific embodiments is intended to describe and illustrate the technical solutions involved in the present invention. Obvious changes or substitutions based on the teachings of the present invention should also be considered to fall within the scope of protection of the present invention. The above specific embodiments are used to disclose the best implementation method of the present invention, so that ordinary technicians in this field can apply various embodiments and various alternatives of the present invention to achieve the purpose of the present invention.
