Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a lifting stretcher bed capable of conveniently passing through the bed and weighing.
Background
The venous thrombolysis of acute ischemic cerebral apoplexy is a treatment method for improving the symptom of neurological deficit of a patient by intravenous infusion of thrombolytic drugs within a certain time window after the onset of the acute ischemic cerebral apoplexy, dissolving thrombus blocking cerebral vessels, recovering cerebral blood flow and saving dying brain tissues.
The time window of acute ischemic cerebral apoplexy intravenous thrombolysis in neurology is within 4.5 hours, so that the time window of thrombolysis is shortened, the dosage of medicine is accurately calculated, the inconvenience brought to patients and families by moving the patients back and forth is reduced, and the stretcher is designed.
The existing stretcher used clinically has no function of measuring the weight, and the dosage of the medicine in intravenous thrombolysis of neurologic ischemic cerebral apoplexy is calculated according to the weight and then used.
In the process of transferring patients with acute ischemic cerebral apoplexy and venous thrombolysis, the stability of the head and the neck is very important, the brain blood circulation of the patients with acute ischemic cerebral apoplexy is not smooth, and the shaking of the head and the neck can lead the carotid artery and the vertebral artery of the neck to be distorted and pressed. Once the morphology of these two important vessels changes, blood flow is impeded and adequate blood is not normally delivered to the brain. After blood supply is further reduced, the degree of ischemia and hypoxia is aggravated, so that more brain cells can be damaged or even die because enough nutrients are not obtained, the subsequent treatment effect is seriously affected, and the disability and death risk of patients is increased. As mentioned in the document, when the carotid artery is distorted by excessive head shaking, blood flow may drop from normal about 30-50 cm per second to 10-20 cm per second, and so the blood flow drops significantly, which has a self-evident negative effect on blood supply to the brain.
Abnormal fluctuation of blood pressure is caused by shaking the head and the neck, which stimulates baroreceptors of human bodies, so that the fluctuation of blood pressure is caused. For acute ischemic stroke patients, the unstable hazard of blood pressure is great. The sudden increase of blood pressure can lead to the burst hemorrhage caused by the fact that the damaged cerebral blood vessel cannot bear the pressure, so that the illness state is rapidly worsened, the sudden decrease of blood pressure can further reduce cerebral perfusion, so that cerebral infarction area is enlarged, and research shows that in the transportation process, the blood pressure fluctuation of a patient with obvious head shaking can exceed the systolic pressure plus or minus 20mmHg and the diastolic pressure plus or minus 10mmHg, and the great fluctuation seriously threatens the life health of the patient.
In the process of passing through the stretcher, the sickbed and the stretcher are in the same horizontal plane, when a patient moves from the sickbed to the stretcher or the patient moves from the stretcher to the sickbed, the patient is positioned on the horizontal moving end of the stretcher, and when the patient moves mutually, a drop is formed so as to be convenient for the transfer of the position of the patient, and the neck and the head of the patient can shake in the process of transferring due to the drop between the sickbed and the stretcher, so that the transfer safety of the patient is affected.
