Description

Hospital patient position acquisition pad, position management system and position management method

Technical Field

The invention relates to the technical field of medical instruments, in particular to a body position collecting pad for a hospital patient, a body position management system and a body position management method.

Background

With the accelerated aging process of the global population, the survival time of the elderly and chronic patients with diseases is prolonged, and the care of the patients lying in bed for a long time also becomes the biggest burden of hospitals and families. In bedridden patients, pressure injury is the most common complication, which not only causes local tissue damage of the patient and increases the pain of the patient, but also when the damage is worsened to a necrotic ulcer stage, the damage can reach the bone surface deeply, bacteria easily enter the blood circulation to cause septicemia and endanger the life of the patient. Research shows that: the prevalence rate of the pressure injury of inpatients in China is 1.57 percent, the incidence rate of the pressure injury of old patients is 3.34 percent, and the incidence rate of the pressure injury of the old patients lying in bed for a long time is up to 25.7 percent. Pressure injuries cause pain and a heavy economic burden on patients, and their treatment consumes a large amount of medical resources. Each medical institution takes the prevalence rate or incidence rate of the pressure injury as an important nursing quality monitoring index and actively explores the influence factors of the pressure injury. The compression time also determines the damage degree of the tissue, the long-time high-pressure effect inevitably leads to the occurrence of pressure damage, and researches show that the tissue can be irreversibly damaged after the compression strength of more than 9.3kPa lasts for 2 hours.

At present, the main method for preventing and treating the pressure injury is to turn over a patient effectively at regular time or directly use a pressure reduction mattress for the patient. According to the recommendation of the American council for pressure sore consultation in the guidelines, the optimal posture change scheme of the patient using the common mattress is 2 h/time to achieve the purpose of preventing the pressure injury. However, frequent turnover is a great consumption of nursing resources, and the current turnover management work cannot completely reach the goal suggested by a nursing guide. The daily turnover workload of nurses is large, and the nursing management of effective turnover of the nurses on patients is directly influenced. Taking a neurology ward of a certain three hospitals as an example, the ward has 50 beds, each nurse nurses at least 8-10 persons in the daytime (7 h), and 24-50 persons in the nighttime (7 h) are different.

In addition, nursing staff cannot scientifically and accurately record the duration time of the compression of a patient, at present, nurses only rely on clinical experience or guidelines to recommend the patient to turn over at a certain frequency, and as the nurses nurse a plurality of patients and the turning-over time of the patients is different, the patients may be turned over when not determined, and the patients are managed to turn over when not determined.

In addition, the spontaneous turnover of the patient must be taken into account, which can lead to repeated nursing of the turnover and increase the nursing cost. In practical situations, a part of patients (58% -61%) have spontaneous turnover phenomena. If the patient turns over spontaneously, the turn-over time is recalculated. However, the patients turn over for 2 h/time (or 4 h/time) recommended by the existing nursing guidelines, and the patients do not consider to turn over spontaneously, nurses only rely on time frequency to carry out turning over nursing, so that the patients are nursed repeatedly, and the burden and nursing resources of the patients are increased.

Establish simultaneously and to indicate last patient position posture on the position monitor of bedside to recommend another kind of position posture according to the nursing guide, when the nursing staff stands up the nursing, can the direct observation position monitoring equipment on the prompt message, directly according to suggestion upset patient, need not like current clinical care, all will take notes patient position change at the nursing book every time.

In some embodiments, the monitor is provided with a warning unit for judging the time when the patient needs to change the body position and reminding a nursing staff according to the pressure data and the body position holding time of each body position of the patient. When the time for changing the body position of the patient is reached, the bedside monitor sends a turn-over prompt to remind a nursing staff of timely changing the body position of the patient, so that the occurrence of pressure injury is prevented.

In some embodiments, a nurse station body position management terminal 5 in wireless communication with the monitor is also included for remotely monitoring patient body position data. The wireless communication needs to realize safe and effective data transmission according to ward conditions, and can flexibly establish a network according to the ward conditions, and the terminal equipment needs low power consumption. The method and the device adopt a mature zigbee wireless connection technology and integrate embedded control, have a star-shaped node connection characteristic, and have incomparable advantages compared with the traditional wired transmission on multi-node forwarding of multi-information concurrency and long-distance transmission. The dual-power supply is adopted, so that the standby time can be still more than 48 hours even under the condition of alternating current power failure, the emergency such as power failure is more leisurely, and a single node can transmit several kilometers in an open area, so that a large number of devices are not required to be arranged in a large hospital, and the pressure on economic cost is low and the cost is low.

In some embodiments, still include the camera 6 to mattress body setting, camera 6 and 5 wireless communication connection of nurse station position management terminal for acquire patient's real-time position and transmit and carry out unified monitoring management for nurse station position management terminal 5.

Example 3

The invention also provides a body position management method, which is suitable for the body position management of the patient by adopting the body position acquisition pad for the patient in the hospital in the embodiment 1 and the body position management system in the embodiment 2, and comprises the following steps:
