Description

Anti-asphyxia device for prone position ventilation therapy

Technical Field

The invention relates to the field of medical auxiliary instruments, in particular to an anti-asphyxia device for prone position ventilation therapy.

Background

Acute respiratory distress syndrome is a clinical syndrome caused by intrapulmonary and/or extrapulmonary causes, characterized by refractory hypoxemia, and is of great interest because of high mortality. The causes of acute respiratory distress syndrome are various, and the pathogenesis of acute respiratory distress syndrome caused by different causes is different. The clinical manifestations are acute onset, respiratory distress, hypoxemia difficult to be corrected by conventional oxygen therapy, and the like; at present, the diagnosis and severity stratification of ARDS are mostly internationally defined by Berlin definition, and the differential diagnosis of ARDS with various diseases is required. The clinical examination contents relate to: diagnosis and differential diagnosis, treatment monitoring and treatment guidance, critical degree and prognosis evaluation and the like; treatment of acute respiratory distress syndrome includes both mechanical and non-mechanical ventilation therapies, and effective treatments continue to be explored.

Treatment of acute respiratory distress syndrome includes both mechanical ventilation therapy and non-mechanical ventilation therapy. Mechanical ventilation is the primary treatment for patients with acute respiratory distress syndrome. According to different mechanical ventilation modes, the method can be divided into non-invasive ventilation and invasive ventilation, the non-invasive ventilation depends on a mask for ventilation, the invasive ventilation depends on a tracheal cannula or a tracheotomy catheter for ventilation, and the two modes need to depend on specific illness conditions to determine the time; at present, the mechanical ventilation strategy for patients with acute respiratory distress syndrome mainly comprises the following: lung protective ventilation strategy: such as small tidal volume ventilation, pressure-limited ventilation, permissive hypercapnia, inverse ventilation, PEEP applications, and the like; lung patency strategy: the specific technology comprises the following steps: pulmonary atelectasis, optimal PEEP application, and selection of mechanical ventilation modes; mechanical ventilation adjuvant therapy: such as intra-airway administration, prone position ventilation, extracorporeal pulmonary oxygenation technology and the like.

Patient prone position ventilation refers to a method in which a patient takes a prone position for mechanical ventilation. The medicine is an auxiliary measure for treating acute respiratory distress syndrome, and the mechanism of the medicine utilizes the action of gravity to increase the blood flow of the front chest and the ventilation of the back and improve the gas exchange. The ventilation method is mainly suitable for patients with severe pulmonary diseases, such as acute respiratory distress syndrome, and can not maintain oxygenation required by normal human bodies through high-intensity breathing machine support. The advantage of this ventilation is that it facilitates blood-gas exchange in the lungs close to the back, improving oxygenation. Typically, two to three treatments are administered a day, each lasting about 20-30 minutes, with care being taken to observe the patient's vital signs during the treatment.

Under the condition that auxiliary equipment is incomplete, the implementation process of prone position ventilation needs at least four or more medical workers to complete together, meanwhile, the risk of certain complications is increased due to the prone position ventilation, and accidents of patients occur in the prone position state, and the documents of emergency treatment methods are few. Therefore, it is recommended that ventilation in prone position should be implemented under sufficient human and material guarantee and complete risk prevention measures and emergency plans.

The existing solution is to set up air cushions at the lower side of the face and the body of the patient when the patient takes the prone position, and set corresponding grooves at the position of the pipeline to prevent the trachea and the like from being extruded, so as to play a preventive role, but does not provide the solution when the pipeline is extruded, and the patient still needs to be closely monitored by trained medical personnel, and the complexion and the vital sign of the patient can be observed at any time, so that the patient can find abnormality in time, and the safety of the prone position ventilation process can be ensured. To this end, we propose an anti-asphyxia device for prone position ventilation therapy.

7. An anti-suffocation device for prone position ventilation therapy according to claim 6, characterized in that: the fine-tuning assembly (605) includes fine-tuning sleeves (605a) and symmetrically distributed on the fine-tuning sleeves (605a) The connecting rod shafts (605b) on both sides, the fine-tuning sleeve (605a) and the connecting rod shaft (605b) are connected by threads, and the connecting rod shaft (605b) on the lower side of the fine-tuning sleeve (605a) is connected to the slide The block (604) is rotatably connected, and the connecting rod shaft (605b) located on the upper side of the fine-tuning sleeve (605a) is rotatably connected to the supporting plate (5).

8. An anti-suffocation device for prone position ventilation therapy according to claim 6, characterized in that: a through groove is opened at the central axis of the upper end surface of the base (1), and the support column (405) is slide in the slot.

9. An anti-suffocation device for prone position ventilation therapy according to any one of claims 1-6, characterized in that: the steps of using the device are as follows:

Step 1, place the device on the hospital bed so that the patient is in a prone position, the chest is attached to the support plate (5), the forehead rests on the upper end of the air cushion (211), and the patient’s cheeks are placed in the air cushion (211) to closely fit, Turn the distance adjustment handwheel (403), and the distance adjustment handwheel (403) drives the slider (401) to slide inside the base (1), so that the torsion plate (404) moves to an appropriate position, and the torsion plate (404) drives the support column ( 405) and the tray seat (3) move, and the tray seat (3) drives the support plate (5) to move to an appropriate position, so that the patient's cervical spine is in a state of natural stretching;

Step 2, after the position adjustment of the supporting plate (5) is completed, turn the angle adjustment handwheel (603), the angle adjustment handwheel (603) drives the slider (604) to move in the horizontal direction, and the slider (604) drives the fine-tuning assembly (605) rotates to change the inclination angle of the fine-tuning assembly (605), and change the extension length of the connecting rod shaft (605b) by rotating the fine-tuning sleeve (605a) to adjust the effective length of the fine-tuning assembly (605), the fine-tuning assembly ( 605) Push the support plate (5) to rotate around the rotation center of the support plate (5) and the support plate seat (3), so that the upper end surface of the support plate (5) fits closely with the chest cavity of the patient;

Step 3: When the patient suffers from suffocation, turn on the power of the hydraulic cylinder (204), the hydraulic cylinder (204) stretches and pushes the fixed rod (205) to move away from the hydraulic cylinder (204), and drives the push rods on both sides (206) is rotated so that the angle between adjacent groups of push rods (206) gradually increases, and the push rods (206) push the top plate (202) connected to it to move upward, so that the position of the patient's head moves upward along the vertical direction. At the same time, the fixed rod (205) pushes the connecting rod (207) to move, and the connecting rod (207) pushes the turning rod (208), so that the bracket (209) rotates around the rotation center connected with the top plate (202), so that The patient's head is raised at a certain angle to stretch the trachea squeezed by the patient's face. After the trachea and trachea are rearranged, the patient's vital signs are observed. After the patient's blood oxygen concentration rises to a safe value, the hydraulic cylinder (204) is controlled to Contraction, so that the position of the patient's head gradually returns to the original state.
