Description

Technical Field

[0001] This utility model relates to the field of medical emergency technology, and in particular to an auxiliary device for emergency response at the scene of an emergency. Background Technology

[0002] In emergency situations involving cardiopulmonary resuscitation (CPR), stretchers are crucial auxiliary equipment, as personnel typically perform chest compressions on the patient while on the stretcher. However, existing emergency stretchers still have several shortcomings in their use:

[0003] Existing stretchers of this type lack specialized compression assistance structures, and the compression depth relies entirely on the operator's experience to control. This can easily lead to situations where excessive compression causes chest injury to the patient, or insufficient compression fails to achieve effective emergency treatment. In addition, stretchers are usually placed on the ground during use, but some ground surfaces do not provide a hard support surface for the patient, which is not conducive to stable emergency treatment.

[0004] Some stretchers equipped with chest compression assistive devices have fixed assistive device structures that cannot be flexibly stored, occupying a lot of space. This is not only detrimental to the rapid transfer and storage of emergency equipment, but also makes it difficult to quickly deploy and use it at the emergency scene, causing many inconveniences to emergency response operations.

[0005] To address the aforementioned problems, this utility model document proposes an auxiliary device for emergency response at first-aid sites. Utility Model Content

[0006] The purpose of this utility model is to solve the shortcomings of existing emergency stretchers, such as the lack of compression assistance structure, difficulty in controlling the compression depth during emergency treatment, easy harm to the patient or unsatisfactory emergency treatment effect, insufficient ground support, and inconvenience in storing some auxiliary components. Therefore, this utility model proposes an emergency treatment auxiliary device for emergency scene.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An emergency response auxiliary device for first aid, comprising:

[0009] The stretcher body has a fixed rigid plate fixedly installed at its bottom, which corresponds to the patient's chest area to provide temporary rigid support;

[0010] It also includes two limiting pressing plates, which are respectively disposed on both sides of the fixed rigid plate. One end of each of the two limiting pressing plates is provided with a corresponding limiting mechanism. The limiting mechanism includes two guide rods and a lifting seat slidably installed on the outer wall of the two guide rods. The limiting mechanism is used to limit the position of the lifting seat on the corresponding guide rod, so as to limit the pressing depth of the limiting pressing plate.

[0011] It also includes two sets of rotating storage mechanisms, the two sets of rotating storage components being used to realize the rotating storage of the two limiting press plates and the corresponding limiting mechanisms.

[0012] In one possible design, the rotating storage mechanism includes two fixed seats fixedly mounted on one side of a fixed rigid plate, with a common rotating seat rotatably mounted between the two fixed seats. Rotating blocks are rotatably mounted on the inner walls of both sides of the rotating seat, and the tops of the two rotating blocks are respectively fixedly connected to the bottom ends of two guide rods. A fixed rod is fixedly mounted inside the lifting seat, and a clearance groove is provided inside the limiting pressing plate near one end. The limiting pressing plate is fitted onto the outer wall of the fixed rod through the clearance groove. A right-angled edge is provided on the bottom side of the limiting pressing plate near the lifting seat, and the limiting pressing plate abuts against the inner wall of one side of the lifting seat through the right-angled edge to ensure the stability of the limiting pressing plate in a horizontal state.

[0013] In one possible design, each of the two fixed seats has a first positioning protrusion on one side close to each other, and each of the two rotating seats has two first positioning grooves at both ends. The two adjacent first positioning grooves are at a 90-degree angle with respect to the rotation center of the rotating seat. The two first positioning protrusions engage with the two adjacent first positioning grooves to position the rotating seat. Each of the inner walls on both sides of the rotating seat has two second positioning grooves, and each of the two rotating blocks has a second positioning protrusion on one side. The second positioning protrusion engages with the two adjacent second positioning grooves. The two adjacent second positioning grooves are at a 180-degree angle with respect to the rotation center of the rotating block.

[0014] In one possible design, the limiting mechanism further includes a collar sleeved on the outer wall of one of the guide rods. The guide rod with the collar has multiple locking holes arranged evenly from top to bottom, and each locking hole has a positioning groove at its center. A push-pull rod slides through the collar, slidingly engaging with the inner walls of the locking holes. A positioning protrusion is fixedly sleeved on the outer wall of the push-pull rod, engaging with the inner walls of the positioning grooves to position the corresponding collar. The collar abuts against the bottom of an adjacent lifting seat to limit its movement.

[0015] In one possible design, a male connector and a female connector are fixedly installed at the ends of the two limiting pressure plates that are close to each other. A magnet is fixedly embedded on the side of the male connector and the female connector that are close to each other. The male connector and the female connector cooperate with each other, and the two magnets are magnetically attracted to each other to complete the connection combination of the two limiting pressure plates.

[0016] In one possible design, a first buffer pad and a second buffer pad are fixedly installed on the bottom of the two limiting pressure plates, respectively. The first buffer pad and the second buffer pad are located at the ends of the two limiting pressure plates that are close to each other, and are used to perform compression cushioning on the patient's chest.

[0017] In one possible design, an elastic fixing strap is fixedly installed on the top of each of the two limiting pressure plates. The two elastic fixing straps are located at the ends of the two limiting pressure plates that are close to each other. The two elastic fixing straps are used to connect the user's hand with the corresponding limiting pressure plate to drive the limiting pressure plate to complete the corresponding lifting and pressing operation.

[0018] In this application, the emergency response auxiliary device for first aid sites, when in actual use, firstly, quickly rotates out two limit pressing plates; during operation, rotate the rotating seat 90 degrees so that the first positioning protrusion on the fixed seat engages in the corresponding first positioning groove at the end of the rotating seat, completing the positioning of the rotating seat. At this time, the rotating seat drives the two guide rods to a vertical state; then rotate the two rotating blocks 180 degrees so that the second positioning protrusion on the rotating blocks engages in the corresponding second positioning groove on the inner wall of the rotating seat, completing the positioning of the rotating blocks. At this time, the guide rods remain vertically upward.

[0019] Next, place the stretcher body on a flat surface and lay the patient flat on it, aligning the patient's chest with the fixed rigid plate at the bottom of the stretcher body. Then, connect the two limiting compression plates, ensuring the male and female connectors mate and their embedded magnets magnetically adhere, completing the assembly of the two limiting compression plates. The assembled limiting compression plates can then be positioned on the patient's chest under gravity. Next, adjust the height of the moving collar so that there is a three-finger distance (approximately 5-6 cm) between the moving collar and the lifting seat. After adjusting the position, press the push-pull rod to insert it into the locking hole at this height. The positioning protrusion engages with the positioning groove in the locking hole to complete the collar positioning. The collar can then abut against the bottom of the lifting seat, thus limiting the lowest position of the lifting seat and determining the compression depth of the limiting compression plates to avoid excessive compression during emergency treatment and causing additional injury to the patient.

[0020] Next, the operator slips their hands into the elastic restraint strap and presses down on the limiting compression plate. The limiting compression plate moves the lifting seat downwards simultaneously through the clearance groove. The first and second buffer pads at the bottom of the two limiting compression plates contact the patient's chest to provide cushioning until the lifting seat abuts against the collar, reaching the preset compression depth. Then, the limiting compression plate is lifted again, and the compression action is repeated to complete the emergency procedure. During the compression, the right-angled edge at the bottom of the limiting compression plate abuts against the inner wall of the lifting seat to ensure that the limiting compression plate remains horizontal and to ensure accurate compression.

[0021] After using the equipment, first separate the two limiting pressure plates to disengage the male and female connectors from their magnetic attraction; move the lifting seat and collar to the bottom of the guide rods, at which point the limiting pressure plates are between the two guide rods; then rotate the two rotating blocks 180 degrees to make the two guide rods point downwards; finally, rotate the rotating seat downwards to complete a 90-degree rotation, which will allow the two guide rods and the limiting pressure plates to be stored in the groove at the bottom of the fixed rigid plate.

[0022] Beneficial effects: The emergency response auxiliary device described in this utility model can accurately control the depth of chest compressions, avoiding additional harm to the patient during emergency operations. The device can adjust the position of the collar on the guide rod, and use the push-pull rod and positioning protrusion to complete the collar positioning. The collar abuts against the lifting seat to limit the lowest position of the lifting seat, thereby determining the compression depth of the limiting compression plate. It does not rely solely on the operator's experience for control, effectively avoiding the problem of excessive or shallow compressions, and improving the standardization of emergency operations.

[0023] In this utility model, an emergency response auxiliary device for first aid sites ensures that the limiting pressure plate remains horizontal during chest compressions, guaranteeing accurate compression. The right-angled edge at the bottom of the limiting pressure plate abuts against the inner wall of the lifting seat, preventing the limiting pressure plate from tilting during compressions. Furthermore, the two limiting pressure plates are fixed together by a male connector, a female connector, and a magnet, ensuring the compression area conforms to the patient's chest, further guaranteeing accurate compression and improving emergency response. Additionally, a fixed rigid plate positioned under the stretcher provides continuous and robust support to the patient's chest, facilitating stable emergency procedures.

[0024] In this utility model, the emergency response auxiliary device at the emergency scene has a rotating storage mechanism that enables flexible storage and rapid deployment of the limiting pressure plate and the limiting mechanism, which can be adapted to the needs of emergency scene use. Through the angle positioning and cooperation of the rotating seat and the rotating block, the device can quickly rotate the guide rod and the limiting pressure plate into the use state. After use, it can also be stored in the groove at the bottom of the fixed hard plate, reducing space occupation and facilitating the transportation and storage of emergency equipment.

[0025] In this utility model, the emergency response auxiliary device at the first aid site has a buffer structure that can reduce the risk of injury to the patient during chest compressions; the first and second buffer pads at the bottom of the limiting compression plate contact the patient's chest, which can play a cushioning role during compressions, reduce the impact caused by direct contact with the hard compression plate, and improve the safety of first aid operations.

[0026] In this invention, the emergency aid device can precisely control the depth of chest compressions. After adjusting and positioning the collar, the collar limits the lowest position of the lifting seat, preventing compressions from being too deep or too shallow, thus improving the standardization of emergency care. The right-angled edge at the bottom of the compression plate prevents tilting, and the fixed hard plate provides chest support, ensuring stability during emergency care. The rotating storage mechanism can be quickly unfolded and stored, reducing space occupation and adapting to the needs of emergency situations. The cushioning pad can reduce the impact of compressions and improve the safety of emergency operations. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] In one embodiment: Refer to Figure 1-6 An emergency response auxiliary device for first aid, comprising: a stretcher body 1, a fixed rigid plate 2, a limiting pressure plate 3, a limiting mechanism, and a rotating storage mechanism, etc.

[0036] In this embodiment, the stretcher body 1 serves as the basic support structure of the entire device, and a fixed rigid plate 2 is fixedly installed at its bottom. The position of the fixed rigid plate 2 corresponds to the patient's chest area. When used at the emergency scene, it can provide temporary rigid support for the patient's chest to meet specific emergency needs.

[0037] In this embodiment, there are two limiting pressing plates 3, which are respectively set on both sides of the fixed rigid plate 2. Each limiting pressing plate 3 is equipped with a corresponding limiting mechanism at one end. The limiting mechanism consists of two guide rods 18 and a lifting seat 19 slidably installed on the outer wall of the guide rods 18. The guide rods 18 provide guidance for the up and down movement of the lifting seat 19. The limiting mechanism can limit the position of the lifting seat 19 on the guide rods 18, thereby realizing the control of the pressing depth of the limiting pressing plate 3.

[0038] Furthermore, in this embodiment, the limiting mechanism includes a collar 22 sleeved on the outer wall of one of the guide rods 18. The guide rod 18 has multiple locking holes 20 evenly arranged from top to bottom inside. Each locking hole 20 has a positioning groove 21 at its center. The collar 22 slides through a push-pull rod 23. The push-pull rod 23 slides and engages with the inner wall of the locking hole 20. The outer wall of the push-pull rod 23 is fixedly sleeved with a positioning protrusion 24. The positioning protrusion 24 engages with the inner wall of the positioning groove 21, thereby positioning the collar 22. The collar 22 abuts against the bottom of the adjacent lifting seat 19, thereby limiting the lifting seat 19. When it is necessary to adjust the pressing depth, push-pull rod 23 is pushed to disengage the positioning protrusion 24 from the current positioning groove 21 and move it outside the locking hole 20. Then, the collar 22 is moved to a suitable position, and the positioning protrusion 24 is pressed into the locking hole 20 and engaged into the new positioning groove 21, thereby locking the collar 22. The positioning protrusion ring 24 is made of rubber to ensure that it has good deformation capacity and sufficient toughness.

[0039] In this embodiment, two sets of rotating storage mechanisms are provided, which are used to realize the rotating storage of the two limiting pressing plates 3 and their corresponding limiting mechanisms. The rotating storage mechanism includes two fixed seats 11 fixedly installed on one side of the fixed hard plate 2. The same rotating seat 13 is rotatably installed between the two fixed seats 11. Rotating blocks 16 are rotatably installed on the inner walls of both sides of the rotating seat 13. The tops of the two rotating blocks 16 are fixedly connected to the bottom ends of the two guide rods 18 respectively. A fixed rod is fixedly installed inside the lifting seat 19. A clearance groove 10 is opened at one end of the limiting pressing plate 3. The limiting pressing plate 3 is sleeved on the outer wall of the fixed rod through the clearance groove 10. A right angle side is provided on the bottom side of the limiting pressing plate 3 near the lifting seat 19. The right angle side abuts against the inner wall of the lifting seat 19 to ensure that the limiting pressing plate 3 can be restricted to a horizontal state when pressed.

[0040] In this embodiment, a male connector 4 and a female connector 5 are fixedly installed on one end of the two limiting pressing plates 3 that are close to each other. A magnet 6 is fixedly embedded on the side of the male connector 4 and the female connector 5 that are close to each other. The male connector 4 and the female connector 5 cooperate with each other, and the two magnets 6 are magnetically attracted to each other, thereby completing the connection combination of the two limiting pressing plates 3 and enhancing the overall stability when pressing.

[0041] This application can be used in the field of medical emergency technology, or in other fields applicable to this application.

[0042] In another embodiment: Reference Figure 4 , 5 An emergency response auxiliary device for first aid, applied in the field of medical emergency technology; the structure of this embodiment is basically the same as the aforementioned embodiment, the difference being:

[0043] Furthermore, in this embodiment, to achieve the positioning of the rotating seat 13, a first positioning protrusion 12 is provided on the side of each of the two fixed seats 11 that are close to each other, and two first positioning grooves 14 are provided at both ends of the rotating seat 13. The two adjacent first positioning grooves 14 form a 90-degree angle with the rotation center of the rotating seat 13, and the two first positioning protrusions 12 engage with the two adjacent first positioning grooves 14. At the same time, two second positioning grooves 15 are provided on the inner walls of both sides of the rotating seat 13, and a second positioning protrusion 17 is provided on one side of each of the two rotating blocks 16. The second positioning protrusion 17 engages with the two adjacent second positioning grooves 15, and the two adjacent second positioning grooves 15 form a 180-degree angle with the rotation center of the rotating block 16. Through the engagement of these positioning protrusions and positioning grooves, the rotating seat 13 and the rotating block 16 can be accurately positioned in the required position, which facilitates the storage and use of the equipment.

[0044] In this embodiment, a first buffer pad 7 and a second buffer pad 8 are fixedly installed at the bottom of the limiting pressure plate 3. They are located at the ends of the two limiting pressure plates 3 that are close to each other. When pressing the patient's chest, they can play a buffering role and reduce damage to the patient's chest.

[0045] In this embodiment, elastic fixing straps 9 are fixedly installed on the top of both limiting pressure plates 3, which are located at the ends of the two limiting pressure plates 3 that are close to each other. During emergency operation, the user can insert his / her hand under the corresponding elastic fixing strap 9 and drive the limiting pressure plate 3 to complete the corresponding lifting and pressing operation by moving his / her hand up and down.

[0046] The working principle and usage process of this technical solution are as follows:

[0047] In actual use, the emergency response auxiliary equipment at the emergency scene first quickly rotates out the two limit pressing plates 3; during operation, the rotating seat 13 is rotated 90 degrees, so that the first positioning protrusion 12 on the fixed seat 11 is engaged in the corresponding first positioning groove 14 at the end of the rotating seat 13, thus completing the positioning of the rotating seat 13. At this time, the rotating seat 13 drives the two guide rods 18 to a vertical state; then the two rotating blocks 16 are rotated 180 degrees, so that the second positioning protrusion 17 on the rotating block 16 is engaged in the corresponding second positioning groove 15 on the inner wall of the rotating seat 13, thus completing the positioning of the rotating block 16. At this time, the guide rods 18 remain vertically upward.

[0048] Next, place the stretcher body 1 on a flat surface and have the patient lie flat on it, aligning the patient's chest with the fixed rigid plate 2 at the bottom of the stretcher body 1. Then, connect the two limiting compression plates 3, making the male connector 4 and the female connector 5 engage, with the embedded magnet 6 magnetically adhering to each other, completing the combination of the two limiting compression plates 3. The combined limiting compression plates 3 can be placed on the patient's chest under the action of gravity. Next, adjust the height of the moving collar 22 so that there is a three-finger distance (about 5-6 cm) between the moving collar 22 and the lifting seat 19. After adjusting the position, press the push-pull rod 23 and insert it into the locking hole 20 at the specified height. The positioning protrusion 24 engages with the positioning groove 21 in the locking hole 20 to complete the positioning of the collar 22. Then, the collar 22 can abut against the bottom of the lifting seat 19, thereby limiting the lowest position of the lifting seat 19 and determining the compression depth of the limiting compression plate 3 to avoid excessive compression during emergency treatment and causing additional injury to the patient.

[0049] Next, the operator slips their hand into the elastic restraint strap 9 and presses down on the limiting compression plate 3. The limiting compression plate 3 moves the lifting seat 19 down synchronously through the relief groove 10. The first buffer pad 7 and the second buffer pad 8 at the bottom of the two limiting compression plates 3 come into contact with the patient's chest to provide cushioning until the lifting seat 19 abuts against the collar 22, reaching the preset compression depth. Then, the limiting compression plate 3 is lifted again, and the compression action is repeated to complete the emergency operation. During the compression, the right-angled edge at the bottom of the limiting compression plate 3 abuts against the inner wall of the lifting seat 19 to ensure that the limiting compression plate 3 remains horizontal and to ensure accurate compression.

[0050] After the equipment is used, first separate the two limiting pressure plates 3 to disengage the male connector 4 from the female connector 5; move the lifting seat 19 and collar 22 to the bottom of the guide rod 18, at which point the limiting pressure plate 3 is between the two guide rods 18; then rotate the two rotating blocks 16 to complete a 180-degree rotation, so that the two guide rods 18 point downwards; finally, rotate the rotating seat 13 downwards to complete a 90-degree rotation, so that the two guide rods 18 and the limiting pressure plate 3 can be stored in the groove at the bottom of the fixed rigid plate 2.

[0051] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
