It is compared with pressure signal, and by the motor-driven valve and air pump of control, is pumped into or excludes the air in gas chamber to adjust in real time
The pressure of tourniquet.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
A kind of tourniquet based on blood pressure automatic adjustment, comprising: cuff 1, blood pressure measuring device 4 and control device 5；Institute
It states and is equipped with cavity inside cuff 1, be equipped with gas chamber 101 in 1 internal cavities of cuff；The gas chamber 101 seals, and can store gas
Body, gas chamber 101 become larger when being filled with gas, increase the pressure that cuff 1 applies limbs；Gas chamber 101 becomes smaller when gas is discharged, and subtracts
The pressure that small cuff 1 applies limbs；The blood pressure measuring device 4 is based on photoplethysmography and measures blood pressure；And blood pressure
The blood pressure signal measured can be output to control device 5 by measuring device 4；After the control device 5 can receive blood pressure signal,
The control device 5 is based on blood pressure signal, and the pressure of the gas chamber 101 is adjusted by controlling the air pump 3.

Pressure.
Above-described embodiment is additionally provided with pressure sensor device 105 in implementation process on the inside of the cuff 1, the pressure passes
Induction device 105 can measure the cuff 1 to limbs pressure applied, and pressure signal is exported to the control device 5.
For above-described embodiment in implementation process, the gas chamber 101 is equipped with inflating port 1011；The inflating port 1011 connects gas
Pump 3；Motor-driven valve 2 is equipped between the air pump 3 and the inflating port 1011；Motor-driven valve 2 described in the air pump 3 is filled in the control
It sets under 5 controls, can be pumped into or be discharged gas into the gas chamber 101.
It is connected between inflating port 1011 and motor-driven valve 2 by hose, is opened in motor-driven valve 2, when 3 forward direction of air pump works, outside
Boundary's air, across the hose, motor-driven valve 2 and inflating port 1011 of connection, is pumped into gas chamber 101 under the action of air pump 3；?
Motor-driven valve 2 is opened, and when 3 reverse operation of air pump, 101 inner air of gas chamber is extracted.
For above-described embodiment in implementation process, photoplethysmography is that blood is detected in living tissue by photoelectricity means
A kind of non-invasive detection methods of liquid volume variation.When light beam is irradiated to skin surface, light beam is by passing transmission or reflection mode
It is sent to photoelectric probe, in the process, due to the breathing attenuation by test side integumentary musculature and blood, detector detection
The luminous intensity arrived will weaken, and wherein integumentary musculature, tissue etc. are to maintain the absorption of light under entire blood circulation and immobilize
, and the volumetric blood in skin changes under action of the heart in pulsation, when the heart contracts, periphery blood volume is most,
Absorbing amount is also maximum, and the luminous intensity detected is minimum；And in diastole, exactly the opposite, the luminous intensity detected is maximum,
Therefore the luminous intensity that photoelectric probe receives is in pulsating nature variation therewith, this light intensity signal is converted into electric signal, can be obtained
The variation of volume pulse blood, to obtain blood pressure signal.
Photoplethysmography the following steps are included:
1), light beam is irradiated to skin surface by the photoelectric probe 104, receives the light beam being reflected back, and detects the light beam

By being inserted into a setting numerical value n, the suitable cuff that improves is applied to the pressure on limbs, to reach better
Haemostatic effect；And set that numerical value n is variable in actual use, due to patient the case where is different, appropriate can change
Numerical value n is set, meets the needs of different patients.
Above-described embodiment is described when pressure value P numerical value is less than the sum of blood pressure BP and setting numerical value n in implementation process
Control device 5 controls the motor-driven valve 2 and gas is discharged in the air pump 3；
When pressure value P numerical value is greater than the sum of blood pressure BP numerical value and setting numerical value n, the control device 5 controls the electricity
Dynamic valve 2 and the air pump 3 are pumped into gas；
When pressure value P numerical value is equal to the sum of blood pressure BP numerical value and setting numerical value n, motor-driven valve 2 is closed, and air pump 3 does not work.
Wherein, in actual use, since blood pressure BP is a undulating value, the mood of patient and action will affect blood
Press BP numerical value, will cause air pump 3 work it is excessively frequent, be unfavorable for the service life of equipment, also waste of energy；Therefore it is pressed in judgement
When force value P numerical value is with the sum of blood pressure BP numerical value and setting numerical value n relationship, step-up error range δ (such as ± 5mmHg) works as pressure value P
For numerical value between the sum of blood pressure BP numerical value and setting numerical value n, numerical difference can determine that pressure value P numerical value away from error range δ
Equal to the sum of blood pressure BP numerical value and setting numerical value n, air pump 3 does not work at this time, thus extend service life of equipment, it is energy saving.
Above-described embodiment in implementation process, in order to more intuitively show blood pressure, pressure value also and setting numerical value n,

Tourniquet provided by the invention based on blood pressure automatic adjustment, when in use, cuff 1, which is sleeved on patient, to be needed to stop blooding
Position proximal part, and block and fix device 1032 with the first fixed device 1031 and second, cuff 1 is fixed；Cuff 1 is fixed to be completed
Afterwards, as shown in step 701, the parameter (such as 20mmHg or 30mmHg) of n is set；After setting up parameter, as shown in step 702,
Photoplethysmography measurement blood pressure is started based on, photoelectric probe 104 works at this time, by beam emissions to skin surface, and connects
The light beam being reflected back, detection is reflected back the intensity variation of light beam, and intensity variation signal is exported and is filled to blood pressure measurement
Set 4；The intensity variation signal received is converted to electric signal by blood pressure measuring device 4, is measured based on photoplethysmography
Pressure value BP out, and pressure value BP is input in control device 5；Meanwhile pressure sensor device 105 measures cuff 1 to limb
The pressure P that body applies, and pressure P is input in control device 5；As shown in step 703, control device 5 works, and controls electronic
Valve 2 is opened and controls the positive work of air pump 3, and outside air is pumped into gas chamber 101 under the action of air pump 3；Or control device 5
Work, control motor-driven valve 2 are opened and control 3 reverse operation of air pump, and gas is discharged in gas chamber 101；Control device 5 compares pressure value
BP and pressure P,
Its theory relation are as follows: pressure value P numerical value is equal to the sum of blood pressure BP numerical value and setting numerical value n；
As indicated in step 704, when pressure value P numerical value is less than the sum of blood pressure BP and setting numerical value n, the control device 5
It controls the motor-driven valve 2 and gas is discharged in the air pump 3；When pressure value P numerical value is greater than the sum of blood pressure BP numerical value and setting numerical value n
When, the control device 5 controls the motor-driven valve 2 and the air pump 3 is pumped into gas；When pressure value P numerical value is equal to blood pressure BP number
When the sum of value and setting numerical value n, motor-driven valve 2 is closed, and air pump 3 does not work；As shown in step 705, when medical and nursing work continues, blood
Pressure measuring device 4 and control device 5 continue working, the pressure applied according to the real-time controlling of blood pressure cuff 1 measured to limbs.
