Description

Technical Field

[0001] The invention relates to the technical field of first aid devices, and in particular to a human body detection first aid device for orthostatic hypotension. Background Art

[0002] Postural hypotension, also known as orthostatic hypotension, refers to a drop in systolic blood pressure of more than 20 mmHg or diastolic blood pressure of more than 10 mmHg in standing position compared with lying position, with or without symptoms such as dizziness or syncope. It not only seriously affects the quality of life of patients, but is also an independent risk factor for falls, syncope, and cardiovascular and cerebrovascular events. Previous epidemiological surveys have found that postural hypotension can be seen in all age groups, but is particularly common in the elderly. The incidence rate in the elderly population over 65 years old can reach 20%. With the increasingly serious problem of population aging, it is of great clinical and social significance to treat postural hypotension, improve the quality of life of patients, and prevent the occurrence of events such as falls and syncope.

[0003] At present, the clinical treatment of postural hypotension includes non-drug treatment and drug treatment, but the means are limited and the effect is poor. Non-drug treatment mainly includes: (1) lifestyle intervention, such as avoiding getting up quickly, taking hot baths, and staying in bed for a long time. However, elderly patients often have cognitive dysfunction and poor compliance; (2) elastic wear therapy: such as wearing elastic stockings and abdominal bands to reduce the blood volume of the lower limb venous bed and increase the amount of blood returning to the heart. Many patients have poor tolerance to elastic stockings and abdominal bands, and elastic treatment has no significant effect on blood pressure and can only slightly relieve symptoms. Drug treatment is mostly used for patients with postural hypotension with severe symptoms and frequent attacks. In addition, up to 50% of patients with postural hypotension have systolic hypertension when sitting or lying, so there is a certain risk of using pressor drugs, which may cause hypertensive emergencies or even hypertensive crises. In summary, the existing methods for treating orthostatic hypotension are limited, and patient compliance is poor. There is still a lack of a medical device that can dynamically monitor patients' blood pressure changes in real time and effectively treat orthostatic hypotension. For this reason, we propose a human body detection first aid device for orthostatic hypotension. Summary of the invention

[0018] Embodiment:

[0019] like Figure 1-3 As shown, a human body detection first aid device for orthostatic hypotension, the first aid device comprises a shell 1, in which a blood pressure measurement module 2, a posture measurement module 3, and a cardiac pacing and data transmission module 4 are arranged in sequence from back to front, and a battery compartment 5 is arranged at the front end of the blood pressure measurement module 2, a posture measurement module 3 is arranged at the front end of the battery compartment 5, a fixing module is arranged at the front end of the posture measurement module 3, the fixing module comprises a threaded shaft 7, a fixing plate base 8, a polymer fixing plate 9, and a fixing contact foot 10, and a pacing electrode 6 is arranged at the front end of the cardiac pacing and data transmission module 4; a blood pressure monitoring sensor is assembled in the blood pressure measurement module 2, the posture measurement module 3 is composed of a posture measurement sensor, a pacing electrode is built-in at the head of the cardiac pacing and data transmission module 4, and a lithium battery is arranged in the battery compartment 5; a micro motor is arranged in the shell 1, and the threaded shaft 7 is rotated by the micro motor; a wireless transmission module is arranged in the shell 1, and the wireless transmission module is connected to a mobile phone or a computer terminal.

[0020] Working principle: The blood pressure measurement module 2 is equipped with a blood pressure monitoring sensor. The sensor generates a periodic electrical signal under the action of the blood pressure in the heart cavity. The amplitude of the electrical signal corresponds to the pressure magnitude, thereby realizing the conversion of the pressure signal into the electrical signal. The battery compartment 5 contains a high-energy storage lithium battery to provide energy supply for the device. The front end of the battery compartment 5 is equipped with a posture measurement module 3, which is equipped with a posture measurement sensor to sense changes in body position. The cardiac pacing and data transmission module 4 has a built-in pacing electrode on the head, and a bipolar pacing mode, which can sense the heart rate of the heart cavity itself, and provide a pacing function through the battery compartment 5. All modules are integrated and delivered to the right venous catheter through a special delivery sheath via the femoral vein. Ventricle, when the pacing electrode 6 reaches the apex, the micromotor drives the threaded shaft 7 to rotate clockwise, so that the fixing plate base 8 moves to the rear end, so that the polymer fixing plate 9 is squeezed and deformed, and then the fixed contact pin 10 extending from the polymer fixing plate 9 bends to the side of the main body and hooks the muscular trabeculae at the apex of the right ventricle, thereby fixing the device, and the micromotor drives the threaded shaft 7 to rotate counterclockwise, so that the fixing plate base 8 moves to the front end, so that the polymer fixing plate 9 is released from the squeeze and restored to smoothness, and then the fixed contact pin 10 is separated from the muscular trabeculae at the apex of the right ventricle, so that the position can be adjusted if it is found that the pacing electrode 6 is not in close contact with the myocardium or the tension is too large during the installation process. After implantation, the device dynamically monitors the patient's blood pressure, heart rate and body position. When any module of blood pressure, posture, and heart rate monitors the patient's non-physiological abnormal signals, such as the patient's supine position turns to the upright position, and the heart chamber pressure decreases, or the heart rate slows down, it is adjusted according to the characteristics of physiological changes, and the device is activated to pace to increase the basal heart rate, increase cardiac output to maintain arterial blood pressure and perfusion of important heart and brain organs. At the same time, relevant data can be sent to mobile phones or computer terminals through wireless data transmission.

[0021] The present invention can implant a miniature medical device through minimally invasive intervention, without any incision scars, and does not affect the appearance. It can functionally monitor the blood pressure, heart rate and body position changes of patients with symptomatic postural hypotension in real time and adjust them according to the characteristics of physiological changes. The patient's lifestyle is not affected and the compliance is good. At the same time, it has wireless data transmission function for clinical doctors to analyze and read.

[0022] In other embodiments, the present embodiment discloses, please Figure 1 As shown, the shell 1 is 25 mm long and 8 mm in diameter, and the shell 1 is made of nickel-titanium alloy; nickel-titanium alloy is an ideal medical biomaterial with good biocompatibility, and is wear-resistant, corrosion-resistant, non-magnetic, and non-toxic.

[0023] In other embodiments, the present embodiment discloses, Figure 1As shown, the housing 1 is formed by 3D printing or mold infusion; the structure of complex parts can be optimized, thereby achieving the advantages of reducing weight, increasing service life, and improving performance.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
