[0002] During the gastric lavage process of poisoning patients, most of them do not cooperate and need medical staff to manually press and restrain. Often due to the choking reaction of patients caused by gastric lavage, patients are very likely to have aspiration or even asphyxia, or oral and digestive tract bleeding, and even arrhythmia and cardiac arrest may occur, resulting in the inability to smoothly perform gastric lavage, or due to the dynamic changes in the patient's body position and posture, resulting in incomplete gastric lavage or excessive gastric lavage causing gastric dilatation, vomiting and abdominal distension, and even digestive tract bleeding and perforation may occur; during gastric lavage, the patient should be in the left lateral position with the head lower than the feet to prevent the lavage fluid from being aspirated into the trachea. At the same time, the patient's head should be turned to one side to prevent vomitus from blocking the trachea;

[0003] However, in the existing posture adjustment and positioning devices, during actual use, the device operation is relatively complex and the functions are single, and it cannot simultaneously meet the lateral lying and head - foot height adjustment of patients, resulting in missing the best rescue opportunity due to device problems during first aid;

[0004] Therefore, this solution proposes a posture adjustment and positioning device for gastric lavage of acute poisoning patients to solve the problems of the existing technology. Summary of the Invention

[0005] In order to solve the above - mentioned technical problems, the present invention designs a posture adjustment and positioning device for gastric lavage of acute poisoning patients. By setting two groups of worm gears and worm shafts under the bed body, the front - back and left - right angle adjustments of the bed body are respectively controlled by the rotation of the motor to better meet the posture adjustment and positioning of patients during gastric lavage. At the same time, rollers are provided under the base so that the device can be quickly moved to the first - aid position according to needs;

[0006] To achieve the above - mentioned technical effects, the present invention is realized through the following technical solutions: A posture adjustment and positioning device for gastric lavage of acute poisoning patients, comprising: a base and a bed body;

[0026] Example 1

[0027] As Figure 1-6 shown, an adjustment support 102 is provided in the middle of the base 1; a second fixed seat 101 is provided at the front end of the adjustment support 102, a limit seat 110 is provided in the middle of the adjustment support 102, and a second fixed seat 101 is provided on the side; a first motor 105 is provided at one end of the first fixed seat 103; a first worm 104 is provided at the front end of the first motor 105 and is rotatably connected to the first fixed seat 103; a second motor 108 is provided at one end of the second fixed seat 101; a second worm 109 is provided at the front end of the second motor 108 and is rotatably connected to the second fixed seat 101; a T-shaped groove is formed in the middle of the limit seat 110 to movably connect a sliding rod 106; a second turbine 111 is provided on one side of the front end of the sliding rod 106 and meshes with the second worm 109, and a sliding wheel 107 is provided at the end of the sliding rod 106; a head baffle 201 is provided at the front end of the bed body 2, a limit plate 203 is provided on the left side, two fixing belts 202 are provided on the bed body 2 in the front-rear direction, and a plurality of fixing grooves 211 arranged side by side up and down are provided at the position of the fixing belt 202 on the side of the bed body 2, and a fixing block 206 is provided at the bottom of the bed body 2 and is fixedly connected to a connecting rod 208; a first turbine 205 is provided at the front end of the connecting rod 208 and meshes with the first worm 104, and the connecting rod 208 is rotatably connected to a rotating seat 209 below; a connecting ring 204 is provided on the left side of the rotating seat 209 and is rotatably connected to the first worm 104, and a sliding seat 207 is provided on the lower right part of the rotating seat 209; a sliding groove 112 is provided in the sliding seat 207 to movably connect the sliding wheel 107; a fixing plate 210 is provided at the front end of the fixing belt 202; rollers 3 are provided below the base 1 for moving the device; a support pillow 212 and a head fixing ring 213 are provided at the front end of the bed body 2; the limit plate 203 is arc-shaped and is internally provided with a soft cotton pad;

[0028] In this embodiment, when the device is in use, first place the poisoned patient on the bed body 2, pull the two fixing belts 202, insert the fixing plate 210 at the front end of the fixing belt 202 into the fixing groove 211 on the side of the bed body 2, and the fixing groove 211 can be inserted into different fixing grooves 211 according to the need of the fixing tightness, and place the patient's head on the support pillow 212, put the forehead part into the head fixing ring 213, and fix the patient's head in the head fixing ring 213 according to the treatment need;

[0029] In this embodiment, when it is necessary to adjust the patient to the lateral position, the second motor 108 is started to rotate, so that the second motor 108 drives the second worm 109 to rotate. The rotation of the second worm 109 drives the second turbine 111 meshing with it to rotate. Since the sliding groove 112 is T-shaped, the end of the sliding rod 106 is limited by the limiting seat 110. Thus, the sliding rod 106 rotates within the T-shaped sliding groove 112, and the sliding wheel 107 at the front end of the sliding rod 106 slides along the sliding groove 112 within the sliding seat 207. Since the front end of the sliding rod 106 is fixed by the limiting seat 110, when the sliding rod 106 rotates, the right end of the bed body 2 will be lifted, thereby tilting the bed body 2 to the left and making the patient reach the lateral position;

[0030] In this embodiment, when it is necessary to adjust the patient to the head-down and feet-up position, the first motor 105 is started to rotate. The rotation of the first motor 105 drives the first worm 104 to rotate. The rotation of the first worm 104 drives the first turbine 205 meshing with it to rotate. The rotation of the first turbine 205 drives the connecting rod 208 to rotate. Since the connecting rod 208 is fixedly connected to the bed body 2 through the fixing block 206, the rotation of the connecting rod 208 will drive the bed body 2 to rotate along the rotating seat 209, thereby tilting the bed body and adjusting the height position of the patient's head and feet;

[0031] In this embodiment, the exterior of the head fixing ring 213 is made of a rigid material, and the interior is provided with a high-density memory foam. The memory foam can adaptively deform according to the shape and pressure distribution of the head, providing better comfort and support. It also has good air permeability and durability; at the same time, a magic tape or an adjustable strap is provided on the head fixing ring 213 for adjustment and fixation according to the size of the patient's head;

[0032] This embodiment provides a preferred embodiment for adjusting the patient's lateral position. In actual production and use, the bed body 2 can be set into left and right halves, which are rotationally connected in the middle. During adjustment, the left bed body 2 can be kept horizontal, and the right bed body 2 can be tilted upward to keep the patient in the lateral position, so that the patient always lies on the horizontal bed body 2, improving the patient's comfort;

[0033] In the prior art, during the gastric lavage process, aspiration or incomplete gastric lavage may occur due to improper patient position. This device can adjust the patient to the optimal head-down and lateral position through the precise control of the worm and worm gear mechanism and the servo motor, thereby reducing the risk of aspiration and improving the efficiency of gastric lavage. The operation of traditional devices is complex and requires the cooperation of multiple medical staff to adjust the patient's position. This device uses electric control to simplify the operation process. Medical staff can quickly and easily adjust the patient to the required position. The fixing belts 202 and the head fixing ring 213 equipped on the device can stabilize the patient's position and reduce the accidental risks caused by the patient's involuntary movements, such as the blockage of the respiratory tract by vomit, etc.; the rollers 3 provided under the base 1 enable the entire device to be quickly moved to the emergency position, saving valuable rescue time;

[0034] In this embodiment, the device can be quickly adjusted according to the needs of different patients and different stages during the gastric lavage process, improving the flexibility and adaptability of the rescue;

[0035] In this embodiment, when designing the device, considering that the device is used for the first aid of acute poisoning patients, the device needs to be quickly and accurately adjusted to the appropriate position during use, and the stability of the device during use should be ensured. The worm and worm gear mechanism can provide a very precise transmission ratio, and the tilt angle of the bed body 2 can be accurately controlled by the motor, meeting the precise requirements for the patient's position during the gastric lavage process. Moreover, the worm gear mechanism has a self-locking characteristic. In the absence of motor drive, the position of the bed body 2 can be locked to prevent the patient from accidentally sliding or moving, increasing the safety of use. And since the patient's weight is loaded on the bed body 2 when the device is adjusted, the worm and worm gear mechanism can generate a large torque, which is crucial for overcoming the resistance brought by the weight of the bed body 2 and the patient and achieving smooth movement;

[0036] At the same time, since the device needs to be moved during first aid, the device should not be too large or too heavy. The structure of the worm and worm gear is relatively compact, and large force transmission can be achieved in a smaller space. Moreover, the worm and worm gear mechanism has high rigidity and can provide stable force transmission to ensure that the bed body 2 will not vibrate or swing accidentally during the adjustment process.

[0037] In summary, the present invention sets a connecting rod 208 under the bed body 2, and the connecting rod 208 is rotationally connected to the rotating seat 209. The turbine one 205 at the front end of the connecting rod 208 meshes with the turbine one 205 provided on the base 1. The motor one 105 rotates to drive the worm one 104 to rotate, thereby driving the turbine one 205 to rotate. The connecting rod 208 drives the bed body 2 to rotate, so as to achieve the adjustment of the head-down position required during gastric lavage and the tilt angle can be adjusted as needed;

[0038] Meanwhile, by providing a limit seat 110 and a second motor 108 on the base 1, when the second motor 108 rotates, it drives the second worm 109 to rotate, thereby driving the second turbine 111 to rotate, driving the sliding wheel 107 to slide along the chute 112 in the sliding seat 207, thus lifting the right side of the bed body 2 and tilting the bed body 2. At the same time, the tilting angle of the bed body 2 can be adjusted according to the rotation angle of the second motor 108, and the patient's body and head are fixed through the fixing belt 202 and the head fixing ring 213 on the bed body 2, preventing the poisoned patient from being uncooperative during gastric lavage, and at the same time, due to the patient's choking reaction during gastric lavage, it is easy for the patient to aspirate or even suffocate, or have oral and digestive tract bleeding or even arrhythmia and cardiac arrest, which may lead to the problem that gastric lavage cannot be carried out smoothly.
