Abstract

The invention discloses an intelligent body position rotation instrument which comprises a single-chip microcomputer and a switch. The intelligent body position rotation instrument is characterized by further comprising an inflator pump, a deflation valve, a back inflation air bag, a digital body position sensor, a pressure sensor, a signal conditioning module, an A/D conversion module and a sound-light alarm module. According to the intelligent body position rotation instrument, the defects that in the monitoring process, a patient is monitored in a hospital, dependence on the sleeping environment is strong, the patient can not fall in sleep easily, and the sensors are prone to falling are overcome. The back inflation air bag with the large size is adopted, the instrument is easy to operate, ingenious in design, convenient to carry and low in cost, under the condition that the sleeping quality of the patient is not affected, the sleeping condition of the patient is further improved, and the intelligent body position rotation instrument is particularly suitable for the patient with obstructive sleep apnea.

Description

Intelligence position rotates instrument

technical field

The present invention relates to a kind of medical intelligent position and rotate instrument, be specifically related to a kind of intelligent position that is applied to Obstructive Sleep Apnea patient and rotate instrument.

Background technology

Obstructive Sleep Apnea (OSAS) is the proemial disease of a kind of tool in sleep disease, refer in sleep procedure due on air flue subside asphyxia and hypoventilation while blocking the sleep causing, with snoring, Sleep architecture disorder, the blood oxygen saturation that takes place frequently reduction, the disease such as daytime is drowsiness.Research shows, obstructive sleep apnea syndrome and hypertension, pulmonary hypertension, arrhythmia, ischemic heart desease, cerebrovascular accident are relevant, are the high risk factors of cardio-cerebral-pulmo angiopathy.According to hygiene department issue health report, crowd's sickness rate of obstructive sleep apnea syndrome is 2%-4%, over-65s old people prevalence reaches 20%-40%, and at Prevalence of Hypertension even up to 50%-90%.At present, China has the patient of the sleep apnea syndrome of 5,000 ten thousand left and right.

For obstructive sleep apnea syndrome general treatment be divided into: fat-reducing, lateral position sleep, continuous positive airway, appliance treatment, operative treatment etc. are several.

The conclusion drawing according to clinical research: " for the relation between obstructive sleep apnea syndrome and position; position when this result of study shows that obstructive sleep apnea syndrome patient sleeps can obviously have influence on the order of severity of sleep apnea and anoxia; while that is to say dorsal position, patient's above-mentioned symptom is more serious; and symptom obviously alleviates when lateral position; show as AHI index less; in sleep, minimum blood oxygen level is higher, generation minimizing of asphyxia and hypoxemia etc. in sleep.

Summary of the invention

In order to reduce the burden of sufferer, adapt to the demand in market, the invention provides a kind of taking low-power scm as core, the inner device that adopts digital body position sensor, the position chanP of monitoring human in sleep procedure, according to the variation of position, makes patient keep lateral position.

The technical solution used in the present invention is: a kind of intelligent position rotates instrument, comprise single-chip microcomputer and switch, it is characterized in that: also comprise inflator pump, vent valve, back aerating gasbag, digital body position sensor, pressure transducer, signal condition module, A/D modular converter, sound and light alarm module; Switch connects Single-chip Controlling instrument and starts, numeral body position sensor is transferred to the position signal sensing in single-chip microcomputer, Single-chip Controlling inflator pump or vent valve carry out inflation/deflation adjustment to back aerating gasbag, pressure transducer detects the air pressure in the aerating gasbag of back, pressure signal is transferred to signal condition module to carry out being transferred to A/D modular converter after signal condition, A/D modular converter feeds back in single-chip microcomputer after analogue signal is converted to digital signal, adjusts charge valve or vent valve.

Further, described pressure transducer is arranged on the lower end of gas tube.

The beneficial effect that the present invention produces is: this device has overcome patient in the process of monitoring and had the monitoring of being in hospital,, difficulty falling asleep strong to sleep environment dependency, the sensor shortcoming such as be easy to come off.We adopt large volume back aerating gasbag; Instrumentation is simple, it is small and exquisite, easy to carry to design, expense is low, in not affecting patient's sleep quality, further improves patient's sleep state, is specially adapted to the patient of obstructive sleep apnea.

Brief description of the drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of an embodiment of the present invention.

Detailed description of the invention

Below in conjunction with drawings and Examples, the invention will be further described:

As shown in Figure 1, the intelligent position rotation instrument in the present invention comprises single-chip microcomputer 1, inflator pump 2, vent valve 3, back aerating gasbag 4, digital body position sensor 8, pressure transducer 5, A/D modular converter 6, sound and light alarm module 9 and switch 7; Switch 7 connects single-chip microcomputer 1 control instrument and starts, numeral body position sensor 8 is transferred to the position signal sensing in single-chip microcomputer 1, inflator pump 2 controlled by single-chip microcomputer 1 or vent valve 3 carries out inflation/deflation adjustment to back aerating gasbag 4, pressure transducer 5 detects the air pressure in back aerating gasbag 4, pressure signal is transferred to A/D modular converter 6, A/D modular converter 6 feeds back in single-chip microcomputer 1 after analogue signal is converted to digital signal, adjusts charge valve 2 and vent valve 3.Sound and light alarm module 9 can be reported to the police to battery electric quantity, and in the time that battery electric quantity is less than 3V, buzzer sends the alarm sound of a 2.5kHz each second, and light emitting diode D3 starts the flicker with 1Hz frequency.

Be illustrated in figure 2 one embodiment of the present of invention.Intelligence position rotates instrument 13 and ties up in sufferer breast abdomen front by fixing band 10, and back air bag 11 is fixed on sufferer back, and gas tube 12 connects intelligent position and rotates instrument 13 and back air bag 11.Switch on power, intelligent position rotates instrument 13 and judges that by digital body position sensor whether sufferer position is in dorsal position, if left and right sides clinostatism is not inflated back air bag 11, also detects air bag air pressure if dorsal position starts 11 inflations to back air bag simultaneously.In the time that air bag air pressure reaches setting pressure, automatically stop inflation, and keep this gasbag pressure constant, detect sufferer position by digital body position sensor simultaneously, if sufferer is dorsal position, maintain back gasbag pressure constant, if judge that sufferer position is as left and right sides clinostatism, start venting.

As long as digital body position sensor has position chanP, intelligent position rotates instrument meeting and automatically judges position, implements inflation/deflation, reaches the object of intelligence adjusting sufferer position.

Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other amendments that those of ordinary skill in the art make technical scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
