Description

Technical Field

[0001] The invention relates to the technical field of medical training equipment, in particular to a training device for trauma first aid simulation. Background Art

[0002] In the field of trauma emergency treatment, cardiopulmonary resuscitation is a vital life support technology. When a patient suffers cardiac arrest due to trauma, cardiopulmonary resuscitation can maintain a certain blood perfusion and oxygen supply to the body's vital organs through artificial circulation and respiratory support, thereby buying precious time for subsequent professional treatment and greatly improving the patient's chance of survival and recovery quality.

[0003] There are two key factors in the process of cardiopulmonary resuscitation: compression frequency and compression force. If the compression force is too large, it may cause the patient to suffer rib fractures, pneumothorax and other chest injuries; if the compression force is too small, it cannot effectively squeeze the heart and cannot establish effective blood circulation in time; if the compression frequency is too fast, the diastole period is too short, and the heart cannot be fully filled with blood, resulting in a decrease in the amount of blood output with each compression; if the compression frequency is too slow, effective blood circulation cannot be maintained, and important organs may suffer irreversible damage due to prolonged ischemia and hypoxia.

[0004] Therefore, the key to saving patients is to use the right strength and frequency during CPR. For novice doctors, simulation training is an essential step due to the complexity of CPR operations and the strict requirements for accuracy. Existing simulation training devices mostly use chest models, which are made of new polymer materials. They are soft and elastic, and the chest rises and falls significantly when pressed, and feel real.

[0005] However, with the existing chest model, the pressing force is difficult to control during training due to different physical conditions of each person. After training, it is difficult to judge whether the pressing force is appropriate, resulting in low training efficiency.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] See also Figures 1 to 9 The present invention provides a technical solution: a training device for trauma emergency simulation, a chest model 1, and also includes an installation cavity 2, which is opened inside the chest model 1; a pressing component 3, which is installed inside the chest model 1; a driving component 4 and a detection block 5, wherein the driving component 4 is installed on one side of the pressing component 3, and the driving component 4 moves when the pressing component 3 is actuated, and the detection block 5 is fixed on the driving component 4, and the driving component 4 drives the detection block 5 to move synchronously when it moves; a detection component 6, which is installed at the end of the driving component 4, and when the detection block 5 moves to the position of the detection component 6, the detection component 6 is actuated; a force feedback component 7, which is installed at the bottom of the installation cavity 2, and the force feedback component 7 feeds back the force after the force exceeds the threshold.

[0039] Through the above technical solution, when performing cardiopulmonary resuscitation training, the operator applies a pressing force on the pressing component 3. Under the action of the pressing force, the pressing component 3 will move up and down. When the pressing component 3 moves up and down, it drives the driving component 4 and the detection block 5 on the driving component 4 to move. When the detection block 5 moves to the detection component 6, the detection component 6 represents the end of one cycle of cardiopulmonary resuscitation. When the pressing force increases, the movement stroke of the pressing component 3 increases, and the single movement amount of the detection block 5 driven by the driving component 4 will also increase. Therefore, within a suitable pressing frequency (the pressing frequency can be silently recited by the operator, and the number of pressings in one cycle is about thirty times under normal circumstances), when the pressing force is relatively large, the contact time of the detection block 5 and the detection component 6 is shorter. If the pressing frequency does not meet the requirement at this time, it means that the pressing force is relatively large. On the contrary, when the pressing force is relatively small, the single movement amount of the detection block 5 will become smaller. Within a suitable pressing frequency, the detection block 5 will not contact the detection component 6, which proves that the pressing force is relatively small.

[0040] Since it is difficult for novice operators to reasonably ensure that the pressing force is maintained within an appropriate range each time, the pressing force is sometimes larger and sometimes smaller. Therefore, during training, within a reasonable frequency, the force may be slightly larger or smaller. At this time, the detection block 5 can also reach the position of the detection component 6 within an appropriate frequency, and the force feedback component 7 can control the threshold of the force. When the pressing force exceeds the threshold, the force feedback component 7 will operate. After the training is completed, it can be judged whether the pressing force is reasonable based on whether the force feedback component 7 operates and whether the detection block 5 reaches the position of the detection component 6 normally, so as to carry out targeted training based on the results after training, which can effectively improve the training efficiency of the trainees and enable them to train the appropriate pressing force in a shorter time.

[0041] Specifically, the pressing assembly 3 includes a pressing rod 8 fixed at the bottom of the chest model 1, a horizontal plate 9 is fixedly installed at the bottom of the pressing rod 8, and the horizontal plate 9 is slidably installed inside the installation cavity 2. At the same time, a return spring 10 is fixedly installed at the bottom of the horizontal plate 9, and the bottom of the return spring 10 is fixed inside the installation cavity 2.

[0042] Through the above technical solution, when the chest model 1 is pressed, the chest model 1 is deformed and drives the pressing rod 8 and the cross plate 9 to move downward in the installation cavity 2. When the cross plate 9 moves downward, it drives the return spring 10 to be compressed. When the trainee retracts the force, the elastic force of the return spring 10 is released, and the pressing rod 8 and the cross plate 9 can return to their initial positions.

[0043] The driving assembly 4 includes an active roller 11 and a driven roller 12 rotating in the installation cavity 2, and a conveyor belt 13 is installed between the active roller 11 and the driven roller 12, and the detection block 5 is fixed on the surface of the conveyor belt 13. When the driving assembly 4 moves up and down, it can drive the active roller 11 to rotate in one direction. Since the pressing assembly 3 moves up and down, a one-way member 14 is also provided in the driving assembly 4. The one-way member 14 can convert the up and down movement of the pressing assembly 3 into a one-way rotation movement of the active roller 11, that is, the one-way member 14 includes a fixed The disc 15 at the end of the active roller 11 has a rotating groove 16 on the outer side of the disc 15, a pawl 17 is rotatably installed in the rotating groove 16, and a limit spring 18 is fixedly installed between the pawl 17 and the disc 15. In addition, a gear 19 is sleeved on the outer side of the disc 15, and the gear 19 rotates on the side of the mounting seat of the active roller 11. One-way grooves 20 are evenly opened on the inner side of the gear 19, and the pawl 17 is engaged in the one-way groove 20. A rack 21 is meshed on the outer side of the gear 19, and the top of the rack 21 is fixed to the bottom of the cross plate 9.

[0044] By means of the above technical solution, when the horizontal plate 9 moves downward, the rack 21 is synchronously driven to move downward, and the rack 21 meshes with the gear 19 when moving downward, so that the gear 19 and the one-way groove 20 in the gear 19 rotate, and at this time, there is no engagement between the pawl 17 and the one-way groove 20, so the rotation of the gear 19 does not drive the disk 15 to rotate. When the horizontal plate 9 is reset upward, the rack 21 moves upward synchronously, and when the rack 21 moves upward, the gear 19 rotates again, but at this time, the one-way groove 20 and the disk 15 are not engaged. 5 is engaged, so when the gear 19 rotates, it will synchronously drive the internal disc 15 to rotate, and when the disc 15 rotates, it will synchronously drive the active roller 11 to rotate. When the active roller 11 rotates, the detection block 5 on the conveyor belt 13 is driven to move along the length direction of the installation cavity 2 through the driven roller 12. When the rack 21 moves downward, the rack 21 is reset upward under the action of the reset spring 10. The more turns the gear 19 rotates, the farther the detection block 5 moves.

[0045] Secondly, the detection component 6 includes a mounting frame 22 fixed in the mounting cavity 2, a first contact block 23 is fixedly installed on the top of the mounting frame 22, a trigger plate 24 is rotatably installed inside the mounting frame 22, a second contact block 25 is fixedly installed on the top of the trigger plate 24, and then an indicator light 26 is installed at the tail of the chest model 1, and the first contact block 23 and the second contact block 25 are connected in series in the circuit of the indicator light 26.

[0046] Through the above technical solution, the detection block 5 will gradually contact the trigger plate 24 during its movement. When the two are in contact, the detection block 5 will generate a thrust on the trigger plate 24, causing the trigger plate 24 to rotate on the mounting frame 22. During the rotation, the trigger plate 24 drives the second contact block 25 to contact the first contact block 23 on the mounting seat. When the first contact block 23 and the second contact block 25 are in contact, the circuit of the indicator light 26 is connected and the indicator light 26 lights up. When the indicator light 26 lights up, if the pressing frequency is appropriate at this time, it indicates that one cycle of cardiopulmonary resuscitation is completed.

[0047] A force feedback component 7 is also installed in the installation cavity 2. The force feedback component 7 includes a pressing plate 27 fixed to the side of the cross plate 9, an airbag 28 is arranged at the bottom of the pressing plate 27, and a one-way valve 29 is installed on the side of the airbag 28. The one-way valve 29 is only used for air intake but not air exhaust. A hose 30 is fixedly installed at both ends of the airbag 28, and a telescopic rod 31 is fixedly installed at one end of the hose 30 away from the airbag 28. The telescopic rod 31 is composed of a sleeve 33 and an adjusting rod 42, wherein one end of the hose 30 is fixed to one end of the sleeve 33 and is connected to the sleeve 33, and a piston rod 34 is slidably installed inside the sleeve 33, and a movable block 32 is also fixed at the end of the piston rod 34, a slider 35 is fixedly installed at the bottom of the movable block 32, and a slide rail 36 is slidably installed at the bottom of the slider 35, and the slide rail 36 is fixed inside the installation cavity 2.

[0048] Through the above scheme, when the pressing plate 27 is in the initial position, a certain safety distance is left between the pressing plate 27 and the airbag 28. When the pressing force is within a reasonable range, the pressing plate 27 will not contact the airbag 28. When the pressing force exceeds the threshold, the pressing plate 27 will contact the airbag 28 to squeeze the airbag 28. After the airbag 28 is squeezed, the gas inside the airbag 28 is released and enters the sleeve 33 through the hose 30. When the pressure in the sleeve 33 increases, it will push the piston rod 34 inside it to move. When the piston rod 34 moves, When the movable block 32 is moved, the movable block 32 will be synchronously driven to move on the slide rail 36. Therefore, after the training is completed, it can be judged whether the movable block 32 has moved, so as to judge whether the pressing force is relatively large during the entire training process. When the movable block 32 is not moved, and the detection block 5 drives the indicator light 26 to light up within a reasonable pressing frequency, it means that the force and frequency are both in normal state. If the movable block 32 is moved, and the detection block 5 also drives the indicator light 26 to light up within a reasonable pressing frequency, it means that the pressing force is relatively large, and the size of the pressing force is judged according to the displacement change of the movable block 32.

[0049] It should be added that, after the airbag 28 is squeezed, the pressing plate 27 is reset and moves away from the airbag 28. At this time, the airbag 28 takes in air through the one-way valve 29, so that the airbag 28 returns to its original state. Secondly, in this embodiment, the airbag 28 contains gas, but considering that the distance between gas molecules is relatively large, when the pressing force of the pressing plate 27 on the airbag 28 is relatively small, the piston rod 34 may not move, or the range of movement is relatively small, and can be replaced by liquid. At this time, the fluid inlet end of the one-way valve 29 can be connected to a water tank.

[0050] Embodiment 2

[0051] Since the pressing force of adults is different from that of children, adults need to press 5-6cm, while children only need to press 3-4cm, and it is even lower for newborns. Therefore, in order to meet the needs of patients of different age groups to be trained through the training device, an adjustment component 37 is installed at the bottom of the airbag 28. The adjustment component 37 can adjust the initial height between the airbag 28 and the pressing plate 27. Specifically, a support seat 38 is fixedly installed at the bottom of the chest model 1, and secondly, the adjustment component 37 includes a sliding plate fixed at the bottom of the airbag 28. Rod 39, the sliding rod 39 and the chest model 1 are slidably connected, the bottom of the sliding rod 39 is rotatably installed with a connecting rod 40, the bottom of the connecting rod 40 is rotatably installed with a crank 41, an adjusting rod 42 is installed inside the crank 41, and a locking member 43 is installed at the end of the adjusting rod 42. The locking member 43 fixes the adjusted crank 41, and the locking member 43 includes a knob 44 fixed at the end of the adjusting rod 42, and the upper and lower sides of the knob 44 are provided with a socket 45, and the inside of the socket 45 is inserted with a limit rod 46, and the limit rod 46 is slidably installed in the support seat 38.

[0052] Through the above technical solution, when it is necessary to perform cardiopulmonary resuscitation training on a newborn or a child, it is only necessary to turn the knob 44. When the knob 44 is turned, the adjusting rod 42 is driven to rotate. When the adjusting rod 42 is turned, the crank 41 is driven to rotate synchronously. When the crank 41 is turned, the sliding rod 39 is driven up and down through the connecting rod 40. Therefore, the airbag 28 can be adjusted to move upward by turning the knob 44. When the airbag 28 moves upward, the initial distance between the airbag 28 and the pressing plate 27 is reduced, and the corresponding pressing force should also be reduced accordingly. After adjustment, the limit rod 46 can be inserted into the socket 45 to limit the knob 44. After the knob 44 is restricted, the airbag 28 can remain in the adjusted position unchanged.
