Referring to fig. 1-3, an embodiment of the present invention discloses a respiratory motion adapter for respiratory degree monitoring and quantification, comprising a mouthpiece 1 and a restraining strip 5;
the mouthpiece 1 comprises a suction inlet 13 and a breathing nozzle 11, and gas is sucked through the suction inlet 13 and enters the oral cavity through the breathing nozzle 11;
a flow sensor and an electric valve part 6 are arranged on the mouthpiece 1 and positioned on the gas inflow path, and can measure the amount of sucked gas and can adjust the opening and closing of the electric valve in a feedback manner;
the restraint strap 5 can be worn on the chest or abdomen of a human body, and is provided with a sensing element 4, a navigation marker interface (not shown in the figure) and a control part so as to know the expansion degree of the chest or abdomen and the time phase of respiratory motion during the respiration of the human body; in addition, the navigation marker interface may be connected to a navigation marker 43 (with a passive marker ball thereon) that may be identified and located by an optical tracker for registration with the high resolution CT image of the chest.
The mouthpiece 1 is in communication connection with the restraint strap 5, and the control part controls the opening and closing of the electric valve part based on the learned inhalation amount and chest expansion. The inhalation amount is detected through the mouthpiece 1 so as to control the inhalation amount to be consistent with the inhalation amount during preoperative scanning chest high-resolution CT when biopsy is carried out on chest lesions or treatment tools are arranged, so that the controllability of the respiratory motion degree in the operation process is maintained, and the displacement influence of the respiratory motion on lung lesions such as lung nodules and the like is reduced. Meanwhile, a navigation marker on the restraint belt is identified and positioned by an optical tracker, and is used for registering the focus space position with the chest high-resolution CT image by combining dual data of the chest expansion degree and the inhalation amount so as to accurately position the instantaneous focus space position of the biopsy.
The electrically operated valve portion herein may be a conventional solenoid valve or an electrically actuated valve as long as a path closing the opening can be achieved.
The invention realizes the communication connection with the restraint strap 5 through the transmission line 2, and can be connected in a wireless mode, and the invention has more reliable signals and strong timeliness through wired connection.
Because of respiration, the size of lung tissue can change along with respiration, and simultaneously, the pleuroperitoneal cavity can also expand and contract. When a patient bites the mouthpiece 1 to breathe through the mouthpiece 1, a flow sensor of the mouthpiece can detect the inhalation amount, and when the inhalation amount reaches a threshold value, the electric valve part 6 closes the mouthpiece to avoid the chest from expanding again; whether the inhalation amount is accurate can be further verified through the chest expansion degree, and the mouthpiece 1 can be directly controlled through the expansion degree;
for pulmonary surgery, after the focus position of a patient is determined by shooting the patient before surgery, whether the patient is in a preoperative respiratory state or not is difficult to ensure in the surgical process, and the focus position is changed due to the change of the chest or abdomen expansion degree, so that the accurate determination of the focus position in the surgery is difficult and only depends on the skilled experience of a doctor and the preoperative shooting prognosis.
The method can solve the problem, ensure the consistency of the breathing state before operation, so that the focus position is close to the prejudgement position, and can model in advance for the medical image before operation so as to guide the doctor in operation more accurately.

Specifically, the first diaphragm 65 is perforated with four first air holes 68, the second diaphragm 67 is perforated with four second air holes 69, the four first air holes 68 and the four second air holes 69 are distributed in a staggered manner, and the four first air holes 68 and the four second air holes 69 are equal in size.

Specifically, the restraining belt 5 includes a first belt 51 and a second belt 52;
the sensing element is a stay cord displacement sensor;
the first belt 51 and the second belt 52 are connected by a pull rope displacement sensor 4.
The first connecting part 41 of the pull rope displacement sensor 4 is fixed at the end part of the first belt 51, the second connecting part 42 is fixed at the end part of the second belt 52, and the other ends of the first belt 51 and the second belt 52 are buckled; or in an adhesive form, and can be conveniently worn by a patient through the design.
For the accuracy of the monitoring, the material of the restraining strip 5 should preferably be a flexible, non-stretchable material.
Specifically, the air holes of the first diaphragm 65 and the second diaphragm 67 are each provided with a one-way flap so that the allowable inhaled air prevents the exhausted air.
Preferably, the valve clack is made of flexible rubber, the cross section area of the valve clack is larger than that of the air hole, and the valve clack is arranged on one side of the downstream position of the air hole, so that air flow smoothly passes through the air hole, and the valve clack covers the air hole to organize the air flow during reverse flow.

In one embodiment of the present invention, the mouthpiece 1 is further provided with an air outlet 12, and the air outlet 12 is located at a position downstream of the air flow path of the second diaphragm 67.
Preferably, a normally closed electromagnetic valve is arranged on the air outlet 12, and the electromagnetic valve is in communication connection with the control part; the control section controls opening and closing of the electromagnetic valve based on the chest expansion.
During inspiration, it is undesirable to exhale to ensure that a fixed amount of inspiration is associated with chest expansion, so it is necessary to provide a normally closed solenoid valve to open the exhalation passageways when required.
In one embodiment of the present invention, the control section has a first priority control level and a second priority control level;
the first priority control level is:
judging whether the air suction amount reaches the air suction amount of the current user at a certain time in the history, if so, closing the electric valve part, and jumping to a second priority control level;
the second priority control level is:
judging whether the chest expansion degree reaches the chest expansion degree of the current user at a certain moment in the history;
if yes, no command is given;
if not, continuing to open the electric valve part, prompting air suction, and closing the electric valve part until the chest expansion degree of the current user at a certain time is reached;
if the chest expansion degree is larger than the preset threshold, the electromagnetic valve of the air outlet 12 is opened, expiration is prompted, and the electromagnetic valve of the air outlet 12 is closed after the chest expansion degree reaches a certain time of the history of the current user.
Further, the first priority control level further includes: judging that when the inhalation amount is close to 80% of the inhalation amount at a certain moment in the history of the current user, controlling the two diaphragms of the electric valve part to be close to each other rather than attached to each other, so that the inhalation resistance is increased, the inhalation of the user or the patient is predicted, and then the preset inhalation amount is reached, and closing the electric valve part. Avoiding the discomfort caused to the patient by suddenly closing the inhalation passage.
That is, the intake air amount has a first threshold value, a second threshold value, and the first threshold value is smaller than the second threshold value; when the air suction amount reaches a first threshold value, the first diaphragm of the electric valve part is controlled to be close to the second diaphragm, a certain gap is kept so that air suction is resistant, and when the air suction amount reaches a second threshold value, the electric valve part is closed.
Although the patient's chest expansion is theoretically consistent with a given inhalation volume, then the patient may be unavoidably mouth during inhalation, nasal ventilation may result in an inhalation volume that does not correspond to the actual inhalation volume, and further control of the inhalation volume by means of the actual monitored expansion volume is required; there is of course also the possibility that the patient's inhalation volume prior to surgery is inaccurate, resulting in an excessive actual chest expansion, at which time the solenoid valve should be opened, allowing the exhalation port 12 to exhale until the predetermined expansion is reached.
Of course, the thresholds of the suction and expansion are not fixed values, and should be allowed to float up and down by a certain proportion, for example 1% -5%, within the error range;
preferably, the control part comprises a display unit 3, a voice prompt unit, a singlechip and a battery module, wherein the singlechip and the battery module are positioned inside the voice prompt unit.
