Abstract
The utility model discloses an artificial airway obstruction or asphyxia warning device. The warning device comprises a pressure detector, alarm apparatus and a comparator. The comparator respectively presets the maximum pressure and the minimum pressure of the artificial airway opening portion of a patient as a high-limit warning value and a low-limit warning value, the comparator compares a pressure signal detected by the pressure detector with the preset high-limit warning value and the low-limit warning value, when the signal is judged to be higher than the high-limit warning value or lower than the low-limit warning value, the comparator transmits a signal to the alarm apparatus, and therefore the alarm apparatus is started. The artificial airway obstruction or asphyxia warning device can detect the pressure of airway of the patient, when the pressure is higher than the high-limit warning value, high-limit warning occurs, a prompt of airway obstruction occurs. When the pressure of the airway is lower than the low-limit warning value for a period, low-limit warning occurs, a prompt of apnea occurs. Specifically, the artificial airway obstruction or asphyxia warning device can conduct acousto-optic continuous warning to prompt medical staff or family members, and therefore the patient is prevented from stifling or even dying.
Description
Technical field
This utility model relates to a kind of artificial airway and blocks/suffocate alarm device.
Background technology
Clinically; the patient who has can successful separating respiratory machine assisted ventilation; but still need to continue to keep artificial airway such as tracheal intubation or tracheotomy; so that airway secretions drain and prevent that mistake from inhaling, such as the patient of some cerebrovascular accidents forfeiture air flue protective capabilities and chronic lung disease patient etc.Because air flue is in open state all the time, the dry expectorant crust obstructing airway that easily forms of air flue; Perhaps, the artificial nose obstruction occurs in sputum ejection easily when the using artificial nose carries out warm and humidization of air flue, as finding and in time removing, will cause the patient to suffocate.In addition, these patients are obnubilation often, and discomfort beyond expression of words, change of illness state are difficult to timely discovery, when particularly not having the monitor monitoring.Even the monitor Real-Time Monitoring is arranged, from airway obstruction, asphyxia, to the vital sign generation significant change that causes the patient, again to the attention that causes medical personnel even family members, and end reaction to go out be that airway obstruction or apneic reason cause, these a series of process need a period of times.If find untimelyly, found perhaps but in time reaction and processing that consequence is hardly imaginable.As everyone knows, any one vital movement of human body be unable to do without to be breathed, and what least tolerate anoxia is exactly brain, and the large cerebral anoxia time surpasses 4-5 minute, namely may cause irreversible brain injury.Therefore, need to effectively monitor these patients' respiratory function, especially when the patient airway obstruction occurs or suffocates, should in time give alert notice medical personnel or family members, avoid unnecessary Injury incidence.
The utility model content
The purpose of this utility model provides a kind of artificial airway and blocks/suffocate alarm device, the sustainable warning reminding medical worker of this alarm device or family members, thereby avoid the patient to suffocate even dead generation, especially working as the patient looks after in the family, when particularly nurse at night dynamics reduces, very necessary.
A kind of artificial airway provided by the utility model blocks/suffocates alarm device, comprises manograph and alarm;
Described alarm device also comprises comparator, this comparator is redefined for respectively high limit alarming value and lower bound alarming value with maximum pressure and the minimum pressure at artificial airway's mouth place of patient, this comparator compares described the manograph pressure signal that detects and the high limit alarming value and the lower bound alarming value that preset, if through judging that this signal is higher than high limit alarming value or is lower than the lower bound alarming value, then comparator starts described alarm to described alarm output signal.
In the above-mentioned alarm device, described comparator with persistent period of the pressure signal at artificial airway's mouth place of patient as the Preset Time value, through described comparator relatively, through judging that the pressure signal that detects when described manograph is higher than the high persistent period of limitting alarming value or being lower than the lower bound alarming value during greater than the Preset Time value, then described comparator is to described alarm output signal, start described alarm, this Preset Time value is generally 10-15 second, can be arranged by operator according to patient's concrete condition.
In the above-mentioned alarm device, described alarm can be audible-visual annunciator.
In the above-mentioned alarm device, the length of described pressure-measuring pipe can be 40 ~ 80cm, and its material can be transparent rigid plastics.
In the above-mentioned alarm device, described manograph, alarm and comparator all are integrated in the electronic pressare-measuring table.
In the above-mentioned alarm device, described electronic pressare-measuring table comprises a pressure display screen, can show in real time the pressure signal that detects.
But the artificial airway that this utility model provides blocks/suffocates alarm device Real-Time Monitoring patient airway pressure, in case when occurring pressure above high limit alarming value, the high limit namely occur and report to the police, the prompting airway obstruction; After airway pressure occurring and being lower than the lower bound alarming value and continuing for some time, lower bound namely occurs and report to the police, the prompting asphyxia; Specifically can continue warning reminding medical worker or family members by acousto-optic, thereby avoid the patient to suffocate even dead generation.
Description of drawings
Sketch map when the alarm device that Fig. 1 provides for this utility model uses, each labelling is as follows among the figure: 1 electronic pressare-measuring table, 2 pressure-measuring pipes, 3 tracheas, 4 artificial airways.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further, but this utility model is not limited to following examples.
As shown in Figure 1, the artificial airway that this utility model provides blocks/suffocates alarm device and comprises an electronic pressare-measuring table 1 and pressure-measuring pipe 2, and electronic pressare-measuring table 1 is connected with pressure-measuring pipe 2; Wherein this pressure-measuring pipe 2 can be made of the transparent plastic stereoplasm tube, and its length is 40-80cm; During use, the other end of pressure-measuring pipe 2 is connected by a tee T with the artificial airway's 4 of the trachea of patients with implantation 3 entrance, is used for measuring the pressure at artificial airway's mouth place; Be provided with a manograph in this electronic pressare-measuring table 1, audible-visual annunciator and comparator (not shown), this comparator is redefined for respectively high limit alarming value and lower bound alarming value with maximum pressure and the minimum pressure at 4 mouthfuls of places of artificial airway of patient, and with persistent period of the pressure signal at 4 mouthfuls of places of artificial airway of patient as the Preset Time value, as being set to 20s according to patient's concrete condition, this comparator compares the manograph pressure signal that detects and the high limit alarming value and the lower bound alarming value that preset, if through judging that this signal is higher than high limit alarming value, and the persistent period is when surpassing the Preset Time value, high limit namely occurring reports to the police, comparator is to the audible-visual annunciator output signal, start this audible-visual annunciator, the prompting airway obstruction; If through judging that this signal is lower than the lower bound alarming value, and persistent period when surpassing the Preset Time value, lower bound namely occurring and report to the police, comparator starts this audible-visual annunciator to the audible-visual annunciator output signal, the prompting asphyxia.
