Description

Technical Field

[0001] The utility model relates to the technical field of injury warning, and in particular to a pressure injury warning device. Background Art

[0002] A pressure injury is a localized injury to the skin and / or soft tissue over a bony prominence, beneath a medical or other device and may present as intact skin or an open ulcer and may be painful.

[0003] Due to the current limitations of nursing human resources in my country and busy clinical work, nurses are unable to conduct timely and effective pressure injury assessments on patients. In addition, there is currently a lack of an early warning system for the prevention of pressure injuries, which results in many problems in nurses' assessments of patients' pressure injuries, such as missed assessments, incomplete assessments, and delayed assessments. As a result, it is impossible to conduct timely detection and early warning before patients may develop pressure injuries, leading to pressure injury problems in patients. Utility Model Content

[0004] The technical problem solved by the utility model is to provide an early warning device for pressure injury, which can realize rapid detection and monitoring of the pressure-exposed parts of the patient's skin, thereby avoiding the problem of pressure injury in the patient.

[0005] The basic solution provided by the utility model: a pressure injury early warning device, including an injury detection mechanism and a remote monitoring mechanism;

[0006] The injury detection mechanism includes a first controller, a first display, a sensing patch, a first alarm, and a first communication module; the sensing patch is provided with a blood circulation sensor; the first controller is electrically connected to the display, the first alarm, the first communication module, and the blood circulation sensor respectively; the sensing patch is provided at a skin pressure site;

[0007] The remote monitoring mechanism includes a second controller, a second alarm, and a second communication module; the second controller is electrically connected to the second alarm and the second communication module respectively;

[0008] The damage detection mechanism and the remote monitoring mechanism are communicatively connected via a first communication module and a second communication module.

[0009] The principle and advantage of the utility model are: in this scheme, when the patient's skin is squeezed, the induction patch is attached to the corresponding skin pressure part, and then the first controller is used to collect blood circulation conditions of the skin pressure part through the blood circulation sensor set on the induction patch, and the first controller is used to judge whether the skin pressure part is too heavy through the blood circulation sensor, and when it is judged that the skin pressure part is too heavy, the first controller is used to alarm through the first alarm and display the collected blood circulation conditions using the first display. In this way, the medical staff next to the patient can realize early detection of the pressure injury, thereby avoiding further aggravation of the pressure injury.

[0010] At the same time, when the first controller detects excessive pressure, it will send an alarm signal to the remote monitoring mechanism through the first communication module. The second controller in the remote monitoring mechanism is used to receive the alarm signal sent by the first communication module through the second communication module. The second controller is used to activate the second alarm for remote alarm after receiving the alarm signal. In this way, after leaving the patient, medical staff can also know the patient's skin compression situation in time through the remote monitoring mechanism, and realize remote monitoring and alarm of whether the patient's skin is damaged by pressure, which greatly reduces the problem of patients suffering from pressure injuries without being discovered in time.

[0011] 1. The setting of the sensor patch realizes the detachable detection of the patient's skin pressure parts. The patient can adjust and match it according to the position of his own skin pressure parts, so as to achieve accurate matching of the skin pressure parts. After all, only the patient knows the specific location of his own skin pressure parts and can find them in the first time, thus realizing rapid detection of skin pressure parts.

[0012] 2. Remote monitoring of whether pressure injury occurs at the compressed part of the patient's skin is achieved through the cooperation between the injury detection mechanism and the remote monitoring mechanism.

[0013] Furthermore, the remote monitoring mechanism also includes a second display electrically connected to the second controller.

[0014] Beneficial effect: The setting of the second display enables remote medical staff to visualize whether the patient has suffered pressure injury, which can better let the remote medical staff know the corresponding situation.

[0015] Furthermore, the first communication module and the second communication module are both wireless communication modules.

[0016] Beneficial effect: The wireless communication method makes the corresponding mechanism deployment simple and convenient.

[0017] Furthermore, the wireless communication module includes one or more of a WIFI module, a Bluetooth module, a mobile communication module, a near field communication module, a ZigBee module, and a Lora module.

[0018] Beneficial effects: Multiple networking modes, more versatile.

[0019] Furthermore, the first alarm and the second alarm both include a warning light and a buzzer.

[0020] Beneficial effect: Dual prompts through sound and light tubes ensure that medical staff can receive alarm reminders.

[0021] Furthermore, the blood circulation sensor includes one or more of a blood pressure sensor, a blood oxygen sensor, and a pressure sensor.

[0022] Beneficial effects: In this solution, comprehensive data collection of normal blood conditions corresponding to the skin pressure areas is achieved through the setting of multiple sensors.

[0023] Furthermore, the damage detection mechanism also includes a delay module electrically connected to the first controller.

[0024] Beneficial effect: In this solution, the first controller is used to start the delay module to delay for a period of time when it detects that the skin pressure part is too heavy, and start the first alarm to alarm. If the skin pressure part is normally compressed during the delay, the delay is stopped and the first alarm is stopped. Otherwise, the delay is maintained until the end, and the delay module sends an end signal. The first controller is used to send an alarm signal to the remote monitoring agency through the first communication module after receiving the end signal, thereby realizing the remote alarm of the remote monitoring agency. In this way, when the compression time is short, the medical staff on the scene are notified in the first time to solve the problem. If the pressure is not normal after the delay, it means that the patient's skin pressure part is being squeezed for a long time and has not received the help of medical staff to relieve it, so the remote medical staff will be notified, so that the pressure on the patient's skin pressure part can be solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 This is a logic block diagram of the early warning device for pressure injury in the first embodiment of the present utility model. DETAILED DESCRIPTION

[0026] The following is further described in detail through specific implementation methods:

[0027] The embodiment is basically as shown in the attached Figure 1 As shown:

[0028] The specific implementation process is as follows: A pressure injury early warning device includes an injury detection mechanism and a remote monitoring mechanism;

[0029] The injury detection mechanism includes a first controller, a first display, a sensing patch, a first alarm, a first communication module, and a delay module; the sensing patch is provided with a blood circulation sensor; the first controller is electrically connected to the display, the first alarm, the first communication module, the blood circulation sensor, and the delay module respectively; the sensing patch is provided at a skin pressure site;

[0030] The blood circulation sensor includes one or more of a blood flow sensor, a blood pressure sensor, a vascular resistance detector, a blood oxygen sensor, a humidity sensor, and a pressure sensor. In this embodiment, the blood circulation sensor uses a pressure sensor and a humidity sensor, and the pressure sensor is a corresponding thin film pressure sensor. In another embodiment, the blood circulation sensor uses a blood flow sensor and a humidity sensor.

[0031] The remote monitoring mechanism includes a second controller, a second alarm, a second communication module, and a second display; the second controller is electrically connected to the second alarm, the second display, and the second communication module respectively;

[0032] The damage detection mechanism and the remote monitoring mechanism are connected in communication via the first communication module and the second communication module. In this embodiment, the remote monitoring mechanism can simultaneously communicate with multiple damage detection mechanisms, thereby achieving synchronous monitoring of multiple damage detection mechanisms by a single monitoring terminal, greatly improving monitoring efficiency.

[0033] When the patient's skin is squeezed, the sensing patch is attached to the corresponding compressed part of the skin. The first controller in the injury detection mechanism is used to collect blood circulation conditions at the compressed part of the skin through the blood circulation sensor arranged on the sensing patch, that is, to collect the pressure and humidity corresponding to the compressed part of the skin through the pressure sensor and the humidity sensor. Based on these data, it is judged whether the compressed part of the skin is over-compressed and there is a possibility of pressure injury, that is, the corresponding pressure is greater than the preset threshold, so as to judge whether the compressed part of the skin is over-compressed. If so, the delay module is started to delay for a period of time, and the first alarm is started to alarm at the same time. If the delay is too long, the pressure sensor is turned on and the pressure sensor is turned off. During the process, if the skin pressure part is under normal pressure, the delay is stopped and the first alarm is stopped. Otherwise, the delay is maintained until the end, and the delay module sends an end signal. The first controller is used to send an alarm signal to the remote monitoring mechanism through the first communication module after receiving the end signal. The second controller in the remote monitoring mechanism is used to receive the alarm signal sent by the first communication module through the second communication module. The second controller is used to start the second alarm for remote alarm after receiving the alarm signal, and display it through the second display module, so that the remote medical staff can know the position of the patient with pressure injury and make timely adjustments. At the same time, the humidity corresponding to the patient's skin pressure part is detected by the humidity sensor to prevent the patient's skin from ulceration due to excessive overtime.

[0034] The first controller and the second controller can be a single-chip microcomputer and a PLC. In this embodiment, both use STM32 series single-chip microcomputers, specifically STM32H7 high-performance series single-chip microcomputers. The delay module can be implemented by a timer built into the single-chip microcomputer, or by a 555 chip and its external circuit to implement the delay function. In this embodiment, the timer inside the single-chip microcomputer is used, and the delay time is 5 seconds. The first alarm and the second alarm both include a warning light and a buzzer. In this embodiment, the warning lights are all red LED lights.

The ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
