Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a human blood distribution optimization device for cardiopulmonary resuscitation. Background Art
[0002] Cardiac arrest (CA) is one of the main causes of adult death worldwide, with millions of cases occurring each year. At present, timely and effective cardiopulmonary resuscitation (CRP) is the only treatment measure for patients with cardiac arrest. The cardiopulmonary resuscitation guidelines recommend minimizing the interruption time and emphasizing the compression depth and compression frequency. However, the survival rate of patients successfully treated for cardiac arrest and discharged from the hospital is <7%, and neurological injury is the main cause of death and disability in patients. During cardiac arrest, hypoxic-ischemic injury and reperfusion injury of important organs such as the heart and brain seriously affect the prognosis of patients. Early and effective cardiopulmonary resuscitation and ensuring the blood perfusion of important organs during the resuscitation process are crucial for minimizing organ damage, restoring organ function, and improving the prognosis of patients. At present, internationally, in addition to increasing the compression depth and compression frequency, there is still a lack of effective treatment means to ensure the perfusion of important organs.
[0003] The anti-G suit is a protective equipment specially designed for pilots to cope with pressure loads in a high-acceleration environment. An important function of the anti-G suit is blood distribution optimization. The pressure effect of the anti-G suit helps to change the blood distribution, enabling more blood to flow to the upper body and the brain. This helps the pilot to maintain clear consciousness and reduce the risk of fainting or losing consciousness in a high-pressure environment.
[0004] According to the principle of blood distribution optimization, an anti-G suit designed a blood distribution optimization device for cardiopulmonary resuscitation to help patients with cardiac arrest prioritize the blood supply to the heart and the brain during cardiopulmonary resuscitation, thereby improving the prognosis of patients. However, the existing anti-G suits in the prior art cannot simultaneously achieve rapid pressurization of multiple airbags. In order to increase the gas pressure in the lower limbs and the lower abdomen, for the blood distribution optimization management of cardiopulmonary resuscitation patients, a pre-hospital cardiopulmonary resuscitation rescue treatment device integrating functions such as rapid pressurization, dynamic pressure monitoring, pressure maintenance, and slow decompression should be developed. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a human blood distribution optimization device for cardiopulmonary resuscitation, which has the characteristics of rapidly increasing the gas pressure in the lower limbs and lower abdomen of patients at an early stage, using a blood flow distribution optimization device to supply a limited blood flow to the brain during cardiopulmonary resuscitation, performing cardiopulmonary resuscitation quickly, and ensuring the rescue effect.
[0006] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A human blood distribution optimization device for cardiopulmonary resuscitation, comprising an air pump provided with an automatic pressure regulating valve, a main air pipe, branch air pipes and an intake valve; further comprising an abdominal pressure belt, a right thigh pressure belt, a left thigh pressure belt, a right calf pressure belt and a left calf pressure belt. The abdominal pressure belt comprises a bandage provided with an outer restraint strip and an inflation unit. There are multiple pairs of the inflation units. Each pair of inflation units comprises a sponge block and an airbag. The sponge block and the airbag have the same length and are arranged side by side. The inflation units are arranged horizontally and connected to the bandage; the right thigh pressure belt, the left thigh pressure belt, the right calf pressure belt and the left calf pressure belt have the same structural shape as the abdominal pressure belt. The lengths of the right thigh pressure belt, the left thigh pressure belt, the right calf pressure belt and the left calf pressure belt are less than the length of the abdominal pressure belt. Each airbag is connected to the air pump through a branch air pipe and the main air pipe.
[0007] For the above-mentioned human blood distribution optimization device for cardiopulmonary resuscitation, the cross-section of the sponge block is trapezoidal with the long bottom side facing upwards, and the cross-section of the airbag is trapezoidal with the short bottom side facing upwards.
[0008] For the above-mentioned human blood distribution optimization device for cardiopulmonary resuscitation, there are 4 - 6 pairs of inflation units on the abdominal pressure belt, and 4 pairs of inflation units are respectively provided on the right thigh pressure belt, the left thigh pressure belt, the right calf pressure belt and the left calf pressure belt.
[0009] For the above-mentioned human blood distribution optimization device for cardiopulmonary resuscitation, the outer restraint strip is a long strip-shaped nylon fastener. There are multiple such nylon fasteners and they are connected to the outer sides of both ends of the bandage.
[0010] For the above-mentioned human blood distribution optimization device for cardiopulmonary resuscitation, it further comprises an air release valve, and the air release valve is installed on the branch air pipe between the airbag and the intake valve.
[0011] The human blood distribution optimization device for cardiopulmonary resuscitation provided by the present invention is provided with an air pump provided with an automatic pressure regulating valve, a main air pipe, branch air pipes and an intake valve; further comprising an abdominal pressure belt, a right thigh pressure belt, a left thigh pressure belt, a right calf pressure belt and a left calf pressure belt. The abdominal pressure belt comprises a bandage provided with an outer restraint strip and an inflation unit. There are multiple pairs of the inflation units. Each pair of inflation units comprises a sponge block and an airbag. The sponge block and the airbag have the same length and are arranged side by side. The inflation units are arranged horizontally and connected to the bandage; the right thigh pressure belt, the left thigh pressure belt, the right calf pressure belt and the left calf pressure belt have the same structural shape as the abdominal pressure belt. The lengths of the right thigh pressure belt, the left thigh pressure belt, the right calf pressure belt and the left calf pressure belt are less than the length of the abdominal pressure belt. Each airbag is connected to the air pump through a branch air pipe and the main air pipe.
[0012] The beneficial technical effects of the present invention are:
[0013] 1. There are multiple pairs of inflation units on the abdominal pressure band, right thigh pressure band, left thigh pressure band, right calf pressure band, and left calf pressure band. Each pair of inflation units includes a sponge block and an airbag. The sponge block and the airbag are arranged side by side. The inflation units are arranged horizontally and connected to the dressing band. This structure wraps around the patient. During the inflation process, the volume of the airbag expands horizontally and vertically and squeezes the sponge block. Since only the airbag needs to be inflated with compressed air and the sponge block only occupies space and does not need to be inflated with compressed air, the amount of compressed air used is saved when the inflation unit expands.
[0014] 2. The cross-section of the sponge block is trapezoidal with the long base facing upward, and the cross-section of the airbag is trapezoidal with the short base facing upward. This structure can cause the sponge block and the airbag to produce an overall inflation effect, enabling the airbag and the sponge block to jointly apply rapid pressure to the human body part.
[0015] 3. The device has a simple structure, is convenient and fast to operate, can achieve rapid inflation and rapid exhaust, comprehensively adjust each pressure band, give priority to ensuring the blood supply to the heart and brain, and thus improve the prognosis of the patient, featuring improved medical staff operation efficiency.
