Technical Field
The utility model belongs to the technology of medical instruments, and relates to a medical device for cardio-pulmonary resuscitation.
Background
The heart-lung resuscitation medical device in the traditional technology comprises a heart extrusion device and a breathing device, wherein the traditional heart extrusion device is generally artificial heart extrusion, the extrusion strength, frequency and matching relation of the artificial heart in the treatment process are operated according to international universal corresponding medical standards, the bone strength of different patients is different, the extrusion operation strength is light and cannot achieve the rescue effect, the rib injury of the patients is possibly caused if the extrusion strength of the artificial heart can meet the standard requirement, and the extrusion strength is closely related to the proficiency of the corresponding skills of rescue medical personnel; the breathing apparatus generally uses a commercial ventilator, and the adjustment function of the commercial ventilator is relatively simple. In the actual treatment process, the patient's condition is complicated and various, and sometimes the matching relationship among the parameters of ventilation, volume, extrusion frequency and extrusion pressure needs to be flexibly adjusted. It is obvious that medical devices for cardiopulmonary resuscitation of the conventional art have difficulty in satisfying such requirements.
Therefore, several medical devices for cardiopulmonary resuscitation having a multi-parameter-dependent control function have been developed.
For example: chinese patent No. CN105749395B discloses a triggered high-frequency jet ventilator for cardiopulmonary resuscitation, which comprises a control unit and a jet ventilator; the control unit is connected with a sensing unit or an artificial heart-lung resuscitator for sensing the fluctuation of the thorax or the respiratory airflow; the control unit sends an air injection starting instruction to the air injection and ventilation device at the end point of the thoracic cavity compression; and sending out a jet stopping command at the end point of the thoracic rebound. According to the technical scheme, the ventilation of the patient is completed under the condition of uninterrupted chest compression, the compression intermittent time is greatly reduced, the ventilation can be accurately performed during the thoracic rebound period of the patient, the perfusion of the coronary artery, the heart and the brain can be effectively improved, and the patient can obtain better prognosis.
The specific technical scheme of the patent comprises a control unit and an injection ventilation device; the jet ventilation device is connected to the artificial airway through an air passage; the control unit is connected with a sensing unit for sensing the fluctuation of the thorax or the respiratory airflow or connected with an artificial heart-lung resuscitator; after receiving the sensing signal sent by the sensing unit or the pressing signal from the artificial heart-lung resuscitator, the control unit sends an air injection starting instruction to the injection ventilation device at the end point of the thoracic pressing; sending an air injection stopping command at the ending point of the thoracic rebound; the jet ventilation device starts jet ventilation or stops jet ventilation to the artificial airway according to the received instruction; the sensing unit is a positioning sensor for monitoring the fluctuation of the thorax; the two positioning sensors are respectively placed at the chest, the abdomen and the back of the patient, or the two positioning sensors are placed at the axillary midline positions at the two sides of the patient; the thorax of the patient is sensed and judged to be in a pressing state or a rebounding state through the distance change among the positioning sensors; in the compression process, when the distance between the two positioning sensors is the minimum, the distance is the end point of thoracic compression, and when the distance is the maximum, the distance is the end point of thoracic rebound; the sensing unit is a flow sensor used for monitoring the air flow change of the air passage in the compression process.
The sensing unit comprises a flow sensor for monitoring the change of airway airflow in the compression process and a positioning sensor for monitoring the change of thoracic fluctuation.
The control unit receives a pressing signal sent by the artificial heart lung resuscitation machine.

the extrusion force is monitored only by a positioning sensor, the extrusion force value is only used for controlling the ventilation device to send an air injection starting or stopping instruction, the protection of the rib of the patient from being damaged is not considered, and the reliability is not high enough.
After the control unit receives the sensing signal sent by the sensing unit or the pressing signal from the artificial heart-lung resuscitator, the control unit sends an air injection starting instruction to the jet ventilation device at the end point of the thoracic pressing; sending an air injection stopping command at the ending point of the thoracic rebound; the jet ventilation device starts jet ventilation or stops jet ventilation to the artificial airway according to the received instruction; the device can only control the correlation between the thorax undulation state and the ejection ventilation state, the control mode is relatively single, the patient's condition is complicated and various, sometimes the matching relation among the parameters of ventilation, air volume, extrusion frequency and extrusion pressure degree needs to be flexibly adjusted, and obviously the device can not achieve the effect.
