Technical Field
The invention relates to the technical field of human body monitoring, in particular to a pressure sore early warning device.
Background
Pressure sores, also known as pressure injuries, pressure ulcers and bedsores, are the complications of patients who are not easy to move or can not move themselves due to the fact that local tissues are pressed for a long time and are subjected to continuous ischemia, hypoxia and malnutrition to cause tissue ulceration and necrosis.
The pressure sore forming is a process, before the pressure sore is formed, the position on the body of a patient, where the pressure sore is easy to occur, is distinguished, and the pressure reduction, massage and other nursing are carried out on the position, where the pressure sore is easy to occur, so that the probability of the pressure sore occurrence of the patient is reduced. At present, the part of the patient with pressure sores is judged by regularly observing whether the skin of the pressed part of the patient has color change, such as purple or brown red, pain, induration, fever and cold.
However, since each person has different body types, weights and body conditions, and the pressure sore easily-prone parts of different persons in different body positions are different, whether the local skin on the body of the patient is the pressure sore easily-prone part or not is judged, and a nursing staff is required to have rich pressure sore management experience. When performing a pressure sore examination, a weak-prone patient must be examined by an experienced nurse, and care and caution must be taken during the examination, otherwise the patient may be injured and the periodic examination may be required, which is practicably and unpalatable to the weak-prone patient. If the patient's health need not to press the sore inspection, and the nurse inspects according to the periodicity, will undoubtedly only increase nursing staff's work on foot, make nurse work efficiency reduce.

The specific implementation process is as follows:
the pressure sore prone position of a bedridden patient is mostly located at a bony prominence without muscle coating or with a thin muscle layer, lack of fat tissue protection and frequent pressure. For example, the supine position: it is easy to occur in the tuberosity of occipital bone, scapular region, elbow, carina, sacral tail and heel. Lateral position: it is easy to occur in ears, acromions, elbows, ribs, hips, medial and lateral sides of knee joints, and medial and lateral ankles. These sites are the high-incidence sites of pressure sores and need to be monitored intensively.
The subcutaneous soft tissue is damaged by pressure or shear forces and the local skin is intact but may appear to change colour such as purple or brownish red, or blisters which cause hyperemia. The soft tissue in these damaged areas may be mushy, exuding, moist compared to the surrounding tissue. In summer, due to factors of air temperature and body temperature, the bedridden patient is easy to sweat at the contact part with the sickbed, and the corresponding body part is easy to be in a wet state.
Therefore, the film type humidity sensors and the film type pressure sensors are arranged at the main part of the bedridden patient, which is in contact with the sickbed, so that the body pressure distribution condition and the body humidity condition of the bedridden patient can be monitored conveniently in real time, and data support is provided for avoiding pressure sores. The pressure signal and the distribution position acquired by the pressure acquisition element are constructed into a pressure distribution diagram of the contact position of the bedridden patient and the sickbed, so that the body of the bedridden patient can form pressure sores conveniently analyzed, doctors and nurses can check the back condition of the patient conveniently, and whether the bedridden patient needs to turn over for massage or not can be analyzed conveniently. Through monitoring and early warning humidity, the bedding can be conveniently replaced by nursing staff or family members in time, and the condition of pressure sore generation is avoided.
Humidity signals and pressure signals collected by the film type humidity sensor and the film type pressure sensor can be processed by the control module to generate a humidity distribution diagram and a human body pressure distribution diagram which are displayed through the display, so that bedridden patients, family members of the patients or nursing staff can conveniently and visually know the conditions of the bedridden patients. Thereby being convenient for analyzing whether the bedridden patient should turn over for massage and changing bed sheets, clothes and the like.
When the control module monitors that the pressure signal is larger than or equal to the critical value and the duration time exceeds the monitoring timing, voice early warning is carried out through the display module, when the bedridden patient, the family members of the patient or the nursing staff receive the early warning, the electronic button switch can be pressed, and the electronic button switch can send feedback information to the warning prompt module. If the electronic button switch is not pressed, the electronic button switch cannot send feedback information to the warning prompt module. The warning prompt module does not receive the feedback information, then plays preset pressure sore hazard audio information, informs the bedridden patient, the family members of the patient or the nursing staff, and achieves the effect of reminding and informing.
