Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a transport device for emergency treatment of critically ill patients. Background Technology
[0002] In the medical field, the treatment and transfer of critically ill patients has always been a crucial link. With the continuous development of medical technology, higher requirements have been placed on the monitoring of vital signs and the level of life support for critically ill patients. At the same time, achieving uninterrupted treatment for critically ill patients in different scenarios, and establishing effective coordination between pre-hospital and in-hospital emergency care, have become important directions for improving the effectiveness of critical care. This not only relates to the life and health of patients but also reflects the treatment capabilities and level of the entire medical system.
[0003] Currently, to provide some level of life support and transport critically ill patients, the common methods used include transporting patients on ordinary stretchers. Respiratory support may rely solely on simple breathing equipment; and monitoring of vital signs generally employs basic monitoring instruments.
[0004] However, the aforementioned technical methods have significant drawbacks. When different equipment and instruments are required, because these devices are often independent and dispersed, it is difficult to quickly assemble them onto ordinary stretchers as needed. This prolongs treatment time, making it difficult to meet the demand for timely and efficient treatment of critically ill patients. It also fails to effectively address the issue of ICU function replacement during the transfer of critically ill patients, and its adaptability to scenarios such as rapid transfer of critically ill patients is poor. Summary of the Invention
[0005] In order to improve the timeliness of treatment during the transfer of critically ill patients, this application provides a transfer device for emergency treatment of critically ill patients.
[0006] The transport device for emergency treatment of critically ill patients provided in this application adopts the following technical solution: A transport device for emergency treatment of critically ill patients includes: a stretcher trolley, the stretcher trolley including a supporting top frame, the supporting top frame having first sliding grooves on both sides of its first end; a functional mechanism, the functional mechanism including a connecting frame and functional components, the connecting frame being U-shaped and detachably connected to the first end of the supporting top frame, the functional components being integrated on the connecting frame, the opposite ends of the connecting frame being sliding portions, the first ends of two sliding portions being connected by a connecting portion to form a U-shape, the sliding portions being correspondingly arranged with the first sliding grooves, the sliding portions being slidably connected to the first sliding grooves, the outer side of the second end of the sliding portions having a first slider, the first slider being correspondingly arranged with the first sliding grooves, the first slider being used to slidably connect to the first sliding grooves; and a first locking mechanism, the first locking mechanism having two sets, the first locking mechanism being correspondingly arranged with the first sliding grooves, the first locking mechanism including a first wedge block. The device comprises a first elastic element and a pulling element. A mounting groove is formed within the first sliding groove. The first end of the first wedge block is slidably connected to the mounting groove. The first elastic element is disposed within the mounting groove, and its two ends are respectively connected to the bottom of the mounting groove and the first end of the first wedge block. The second end of the first wedge block has an inclined surface facing the first end of the support frame, allowing the first slider to push the first wedge block to compress the first elastic element. After the first slider passes the first wedge block, the first wedge block restricts the first slider from retracting towards the first end of the support frame. The first end of the pulling element is connected to the first wedge block, and the second end of the pulling element extends outside the support frame. The first end of the pulling element is slidably connected to the support frame, and the cross-sectional area of the second end of the pulling element is larger than the cross-sectional area of the first end of the pulling element.
[0007] By adopting the above technical solution, the stretcher trolley provides a basic support structure and mobility function for the transfer device. The support top frame is used to connect the functional mechanism, and the first slide grooves on both sides provide tracks for the sliding of the functional mechanism. The connecting frame of the functional mechanism is U-shaped and detachably connected to both sides of the first end of the support top frame, facilitating installation and disassembly. The functional components are integrated on the connecting frame, enabling emergency-related operations for critically ill patients. The sliding part of the connecting frame and the first slider are slidably connected to the first slide groove, allowing the functional mechanism to move along the first slide groove, facilitating position adjustment and disassembly / reassembly. The mounting groove provides installation space for the first wedge block and the first elastic element of the first locking mechanism. Under the action of the first elastic element, the inclined surface of the first wedge block can compress the first elastic element when the first slider is pushed, and reset after being pushed to limit the first slider from retracting towards the first end of the support top frame, thereby achieving locking and positioning of the functional mechanism. The pull member is used to control the position of the first wedge block. Its second end has a large cross-sectional area, which can release the locking and positioning effect on the first slider by pulling, thereby ensuring the normal operation of the first locking mechanism. This improves the stability and operability of the transfer device as a whole, and ensures the timely realization of emergency functions during the transfer of critically ill patients.
[0008] Optionally, the functional components include multiple functional parts distributed on the connecting frame, and the multiple functional parts include CRRT, ventilator, ECMO, defibrillator monitor, power supply, infusion unit and oxygen cylinder.
[0009] By adopting the above technical solutions, emergency transport-type CRRT can provide liver and kidney function replacement during the mobile transport of critically ill patients; transport ventilators can provide spontaneous ventilation during the mobile transport of critically ill patients; transport ECMO can provide cardiopulmonary function replacement during the mobile transport of critically ill patients; defibrillator monitors can monitor vital signs and resuscitate cardiac arrest in critically ill transported patients; the emergency transport-type CRRT power supply provides power to the CRRT; the infusion unit can administer medication and control the infusion rate for critically ill transported patients; and the oxygen cylinder provides oxygen to critically ill transported patients. These functional components are distributed on the connecting frame, enabling joint support of artificial heart-lung and artificial liver-kidney during mobile transport, realizing ICU monitoring and treatment functions, solving the problems of ICU function replacement and life support during the transport of critically ill patients, improving the safety and treatment efficiency of critically ill patients during transport, and increasing the safety of transport and survival rate of critically ill patients.
[0010] Optionally, the first locking mechanism further includes a cover, the cover being U-shaped, and the support top frame having an insertion slot, the two ends of the cover being used to insert into the insertion slot.
[0011] By adopting the above technical solution, the cover is U-shaped, and its two ends are inserted into the insertion slots on the support top frame, which can protect the first locking mechanism and prevent it from being affected by external collisions or dust, thus ensuring the normal operation and service life of the first locking mechanism. At the same time, this insertion connection method facilitates the installation and disassembly of the cover, making it convenient for the maintenance and repair of the first locking mechanism.
[0012] Optionally, the cover can surround the outer periphery of the first end of the pull member and engage with the second end of the pull member on the side near the first end of the pull member. The distance between the two ends of the cover is greater than the diameter of the first end of the pull member and less than the maximum length of the second end of the pull member. The width of the cover is equal to the distance between the second end of the pull member and the surface of the support top frame when the first elastic member is compressed, so that the cover can be used to restrict the second end of the pull member from moving towards the first slide groove.
[0013] By adopting the above technical solution, the cover is surrounded on the outer periphery of the first end of the pulling member, which can protect the first end of the pulling member; the cover is snapped onto the side of the second end of the pulling member close to the first end of the pulling member, and the distance between its two ends is greater than the diameter of the first end of the pulling member and less than the maximum length of the second end of the pulling member, which can effectively restrict the second end of the pulling member from moving towards the first slide groove. Thus, when it is necessary to release the locking effect, it ensures that the first wedge block in the first locking mechanism releases its limiting and retracting effect on the first slider, and ensures the detachability of the connection between the functional mechanism and the stretcher trolley.
[0014] Optionally, the first end of the sliding part is provided with a second slider, which slides in cooperation with the first groove.
[0015] By adopting the above technical solution, a second slider is provided at the first end of the sliding part, which can provide a structural basis for subsequent engagement with other components (such as the second locking mechanism), making it easier to position and fix the functional mechanism on different components; at the same time, it can improve the sliding stability of the sliding part.
[0016] Optionally, a buffer pad is provided at the second end of each of the two sliding parts.
[0017] By adopting the above technical solution, the buffer pad set at the end of the sliding part can play a buffering role when the sliding part comes into contact with other components, reduce the impact force generated by the collision, avoid damage to the device due to the collision, further improve the stability and reliability of the device, and ensure the smooth and safe transfer of critically ill patients.
[0018] Optionally, it also includes a movable frame, which is provided with two sets of second sliding grooves. The second sliding grooves correspond to the sliding part and are used for sliding connection. The second sliding grooves are provided with a second locking mechanism. The second locking mechanism has the same structure as the first locking mechanism. The second slider is used to selectively engage with the second locking mechanism.
[0019] By adopting the above technical solution, the two sets of second sliding grooves on the movable frame correspond to and can be slidably connected to the sliding part, which facilitates the movement and positioning of the functional mechanism on the movable frame. Moreover, the second locking mechanism has the same structure as the first locking mechanism, so that the locking method on the movable frame is similar to that on the supporting top frame, which is convenient for operation and maintenance. The second slider and the second locking mechanism cooperate to lock together, which can firmly fix the sliding part in the second sliding groove, prevent the functional mechanism from sliding and shifting under non-human operation, and ensure the stability and safety of the overall structure.
[0020] Optionally, the functional component has a mounting plate at its bottom, and two sets of connectors are provided on the side of the mounting plate away from the functional component. Each connector includes a connecting rod and a connecting ball. One end of the connecting rod is connected to the mounting plate, and the other end of the connecting rod is connected to the connecting ball. A support is provided on the connecting frame, and one end of the support is connected to the connecting frame. A bearing platform is provided at the other end of the support. The bearing platform has two sets of arc-shaped slots. The width of the arc-shaped slots is equal to the diameter of the connecting ball and greater than the diameter of the connecting rod. A third locking mechanism is provided at one end of the arc-shaped slots. The third locking mechanism is used to selectively lock the connecting ball to prevent the functional component from detaching from the bearing platform.
[0021] By adopting the above technical solution, the mounting plate at the bottom of the functional component is used to install the connector. The connecting rod of the connector connects the mounting plate to the connecting ball, facilitating the connection between the functional component and the support platform. The support member on the connecting frame supports the support platform. The width of the arc-shaped groove on the support platform is equal to the diameter of the connecting ball and larger than the diameter of the connecting rod, allowing the connecting ball to move within the arc-shaped groove. The third locking mechanism can selectively lock the connecting ball, thereby effectively preventing the functional component from detaching from the support platform, ensuring the stability of the functional component's installation on the transfer device, and guaranteeing that the functional component can function normally during transfer, providing reliable support for the emergency treatment of critically ill patients.
[0022] Optionally, the third locking mechanism includes a second elastic element and a second wedge block. The bearing platform has a receiving cavity located on one side of the arc-shaped slot. The first end of the second elastic element is connected to the inner wall of the receiving cavity, and the second end of the second elastic element is connected to the first end of the second wedge block. The second end of the second wedge block has an inclined surface facing upward, so that the downward movement of the connecting ball can push the second wedge block to move. The second wedge block is used to lock the connecting ball.
[0023] By adopting the above technical solution, the receiving cavity of the bearing platform provides installation space for the second elastic element and the second wedge block. The second elastic element connects the inner wall of the receiving cavity and the second wedge block, and can provide elastic buffering and reset function when the connecting ball moves down to push the second wedge block to move. The inclined surface on the second wedge block is set upward, which facilitates the connecting ball to move down to push it. When the connecting ball enters the arc-shaped slot, the second wedge block engages with the connecting ball, which can effectively limit the functional component from detaching from the bearing platform and improve the installation stability of the functional component on the bearing platform.
[0024] Optionally, the third locking mechanism further includes a limiting member. The bearing platform is provided with a first limiting hole, and a first magnetic attraction member is provided at the bottom of the first limiting hole. The mounting plate is provided with a second limiting hole that extends vertically through the plate. The second limiting hole is used to align and cooperate with the first limiting hole. A second magnetic attraction member is provided at the lower end of the limiting member. The limiting member is used to pass through the first limiting hole and the second limiting hole. The second magnetic attraction member is used to attract the first magnetic attraction member. The limiting member is used to restrict the rotation of the functional component relative to the bearing platform.
[0025] By adopting the above technical solution, a first magnetic suction component is provided at the bottom of the first limiting hole of the bearing platform. The second limiting hole that runs vertically through the mounting plate is aligned and engaged with the first limiting hole. The second magnetic suction component at the lower end of the limiting component is attracted to the first magnetic suction component, so that the limiting component can pass through the first limiting hole and the second limiting hole. This can effectively restrict the rotation of the functional component relative to the bearing platform, ensure the installation stability of the functional component on the bearing platform, and thus ensure the normal operation of each functional component during the use of the transfer device. At the same time, when disassembly is required, the limiting component can be removed so that the mounting plate can be rotated to release the locking effect.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The transport ECMO in the transport device can realize cardiopulmonary function replacement during the mobile transport of critically ill patients, and the emergency transport CRRT can realize liver and kidney function replacement during the mobile transport of critically ill patients. The two work together to realize the joint support of artificial cardiopulmonary function and artificial liver and kidney during the mobile transport process, and solve the functional replacement and life support of ICU during the transport of critically ill patients. 2. The connecting frame of the functional mechanism is slidably connected to the first slide groove of the stretcher support top frame through the sliding part and the first slider, and the first slider is restricted from retraction by the first locking mechanism; the second slide groove of the mobile frame is slidably connected to the sliding part of the functional mechanism, and is locked in place by the second locking mechanism with the same structure as the first locking mechanism. This connection method through the slide groove and the locking mechanism allows the functional mechanism to be quickly assembled and disassembled with the stretcher, mobile frame, etc., improving the safety and treatment efficiency of critically ill patients during the transfer process; 3. The transport device includes multiple functional components such as CRRT, ventilator, ECMO, defibrillator and monitor, which can realize ICU monitoring and treatment functions, and improve the safety of transporting critically ill patients and the survival rate of treatment.

[0039] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.
[0040] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.
[0041] like Figure 1 As shown in the figure, this application discloses a transport device (hereinafter referred to as "device") for emergency treatment of critically ill patients. The device includes a stretcher 1, a functional mechanism 2, and a first locking mechanism 3. By using a stretcher 1 to carry the functional mechanism 2 and fixing it with the locking mechanism, the device achieves the effect of ensuring the safety of transporting critically ill patients.
[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the functional mechanism 2 is detachably connected to the first end of the support top frame 11 of the stretcher 1. The first locking mechanism 3 is set in the first slide groove 111 of the support top frame 11 to restrict the sliding part 211 of the connecting frame 21 of the functional mechanism 2 from retracting, thereby realizing a stable connection between the functional mechanism 2 and the stretcher 1, which facilitates the provision of necessary functional support when transporting critically ill patients.
[0043] In this embodiment, the stretcher trolley 1 can be selected from existing structures as needed, such as an electric stretcher trolley 1, an ambulance stretcher, etc.; it is understood that the cooperation structure between the ambulance and the stretcher trolley can still use the original structure. Specifically, the stretcher trolley 1 includes a support top frame 11, which plays a role in bearing and supporting. The support top frame 11 is usually made of high-strength metal material, such as stainless steel or aluminum alloy, to ensure that it has sufficient strength to bear the weight of the functional mechanism 2 and the patient. The first end of the support top frame 11 is provided with a first sliding groove 111 on both sides. The first sliding groove 111 can be a groove structure processed by milling, casting, or other processes, for cooperating with the connecting frame 21 of the functional mechanism 2.
[0044] like Figure 3 , Figure 4 and Figure 5 As shown, the functional mechanism 2 includes a connecting frame 21 and a functional component 22. The connecting frame 21 is U-shaped. This U-shaped structure design allows for easy connection to the first end of the supporting top frame 11 and facilitates the arrangement and support of the functional component 22. The two opposite ends of the connecting frame 21 are sliding portions 211, and the first ends of the two sliding portions 211 are connected by a connecting portion 212 to form a U-shape. The sliding portions 211 are correspondingly arranged with the first sliding groove 111 and are slidably connected to the first sliding groove 111. A first slider 213 is provided on the outer side of the second end of the sliding portion 211. The first slider 213 is also correspondingly arranged with the first sliding groove 111 and is used to slidably connect to the first sliding groove 111. The first slider 213 can be fixed to the sliding portion 211 by bolts, welding, or other means. Its material can be the same as or similar to the connecting frame 21, and its surface can be polished to reduce friction with the first sliding groove 111 and facilitate sliding. Alternatively, the first slider 213 can also be engaged with the sliding portion 211 by a slot.
[0045] like Figure 3 , Figure 4 and Figure 5As shown, the functional component 22 is integrated on the connecting frame 21. The functional component 22 includes multiple functional parts 221, which are distributed on the connecting frame 21. The multiple functional parts 221 include CRRT, ventilator, ECMO, defibrillator monitor, power supply, infusion unit and oxygen cylinder. All functional parts 221 adopt existing technology, and the specific type can be selected as needed. Among them, CRRT is used to replace liver and kidney function during the transport of critically ill patients. It can be an independent device unit connected to the patient through tubing to perform functions such as blood filtration. Ventilators are used to replace spontaneous ventilation during the transport of critically ill patients. They usually have different ventilation modes and parameter settings to meet the needs of different patients. ECMO is used to replace cardiopulmonary function during the transport of critically ill patients. It consists of an extracorporeal circulation system and can draw the patient's blood out of the body for oxygenation and other treatments before returning it to the body. Defibrillators are used to monitor vital signs and resuscitate cardiac arrest patients during transport. They can monitor the patient's heart rate, blood pressure and other vital signs in real time and perform defibrillation when necessary. Power supply components provide power to emergency transport CRRT and other equipment, and can be rechargeable power sources such as lithium batteries. Infusion components are used to administer medication and control the infusion rate for critically ill patients during transport. They can be devices such as infusion pumps. Oxygen cylinders provide oxygen to critically ill patients during transport. Oxygen cylinders are generally made of high-strength steel and are connected to the patient's breathing equipment through valves and tubing. The combination of these functional components 221 enables the transport device to simulate the function of an ICU during transport, providing comprehensive life support for the patient.
[0046] When using this device, the patient's condition can be assessed first, and different devices can be activated based on the patient's selection, with treatment parameters set to ensure stable operation of all devices before transfer. Furthermore, during transport, the power supply can utilize the devices' built-in batteries, and the gas supply can use the device's own oxygen. Upon arrival in the ambulance, the ambulance's power and gas supply can be switched; upon disembarking, the devices can be switched back to their own batteries, and the gas supply can be switched back to the device's own oxygen. Upon arrival at the destination, a professional physician will coordinate with the equipment to complete the transfer. Alternatively, treatment can continue after arrival at the destination, depending on the actual situation.
[0047] like Figure 3 , Figure 5 and Figure 6As shown, the first locking mechanism 3 has two sets, corresponding to the first slide groove 111. The first locking mechanism 3 includes a first wedge block 31, a first elastic element 32, and a pulling element 33. The first slide groove 111 has a vertically extending mounting groove. The first end of the first wedge block 31 is slidably connected to the mounting groove. The first elastic element 32 is located in the mounting groove, and its upper and lower ends are respectively connected to the bottom of the mounting groove and the first end of the first wedge block 31. The first elastic element 32 is usually a spring. When the first slider 213 pushes the first wedge block 31, the spring is compressed and stores elastic potential energy. The second end of the first wedge block 31 has an inclined surface, which faces the first end of the support top frame 11. In this way, when the first slider 213 slides into the first slide groove 111, it can push the first wedge block 31 to compress the first elastic element 32. After the first slider 213 passes the first wedge block 31, the first wedge block 31 resets to limit the first slider 213 from retracting towards the first end of the support top frame 11.
[0048] The first end of the pulling member 33 is connected to the first wedge block 31, and the second end extends to the outside of the support top frame 11. The first end of the pulling member 33 is slidably connected to the support top frame 11, and the cross-sectional area of the second end of the pulling member 33 is larger than the cross-sectional area of the first end of the pulling member 33. When it is necessary to disassemble the functional mechanism 2, the pulling member 33 is pulled, causing the first wedge block 31 to retract into the mounting sleeve against the spring force, thereby releasing the restriction on the first slider 213.
[0049] like Figure 3 , Figure 5 and Figure 6 As shown, the first locking mechanism 3 also includes a cover 34, which is U-shaped. The support top frame 11 has insertion slots, and both ends of the cover 34 are used to insert into these slots. The U-shaped cover 34 surrounds the outer periphery of the first end of the pulling member 33 and engages with the side of the second end of the pulling member 33 near the first end. The distance between the two ends of the cover 34 is greater than the diameter of the first end of the pulling member 33 and less than the maximum length of the second end of the pulling member 33. The width of the cover 34 is equal to the distance between the second end of the pulling member 33 and the surface of the support top frame 11 when the first elastic member 32 is compressed. This allows the cover 34 to restrict the movement of the second end of the pulling member 33 towards the first sliding groove 111, preventing the first locking mechanism 3 from reliably releasing its locking action when disassembling the functional mechanism 2, thus ensuring the reliability of the first locking mechanism 3. Alternatively, the cover 34 can also be connected to the support top frame 11 by means of snap-fit or other methods.
[0050] The first end of the sliding part 211 is provided with a second slider 214, which slides in conjunction with the first sliding groove 111 to improve sliding stability and support reliability. Both sliding parts 211 have buffer pads at their second ends to reduce the impact during installation.
[0051] like Figure 3 , Figure 5 and Figure 7 As shown, the transfer device also includes a movable frame 4. The upper end of the movable frame 4 is provided with two sets of opposing second sliding grooves 41. The second sliding grooves 41 correspond to the sliding part 211 and are used for sliding connection. A second locking mechanism (not shown in the figure) can be provided on the second sliding groove 41. The second locking mechanism has the same structure as the first locking mechanism 3, and the second slider 214 is used to selectively engage with the second locking mechanism. The movable frame 4 also includes movable components, such as a movable and lifting structure under the support top frame 11 of the stretcher trolley 1, or other forms of movable frames, such as a support with wheels, so that the functional mechanism 2 can be easily transferred from the stretcher trolley 1 to other transport vehicles or locations, realizing transfer in different scenarios.
[0052] like Figure 3 , Figure 8 and Figure 9 As shown, the bottom of the functional component 221 is provided with a mounting plate 222, which is fixedly connected to the functional component 221.
[0053] like Figure 3 , Figure 8 and Figure 10 As shown, the mounting plate 222 has two sets of connectors 223 on the side away from the functional component 221. The connectors 223 include a connecting rod 2231 and a connecting ball 2232. One end of the connecting rod 2231 is connected to the mounting plate 222, and the other end is connected to the connecting ball 2232.
[0054] like Figure 3 , Figure 9 and Figure 11 As shown, the connecting frame 21 is provided with a support member 215. One end of the support member 215 is connected to the connecting frame 21, and the other end is provided with a bearing platform 216. The bearing platform 216 is provided with two sets of arc-shaped slots 2161. The width of the arc-shaped slots 2161 is equal to the diameter of the connecting ball 2232 and greater than the diameter of the connecting rod 2231. One end of the arc-shaped slots 2161 is provided with a third locking mechanism 217. The third locking mechanism 217 is used to selectively lock the connecting ball 2232 to prevent the functional component 221 from disengaging from the bearing platform 216.
[0055] like Figure 3 , Figure 9 and Figure 11As shown, the third locking mechanism 217 includes a second elastic element 2171 and a second wedge block 2172. The bearing platform 216 has a horizontally extending receiving cavity, which is located on one side of the arc-shaped slot 2161 and is interconnected. The first end of the second elastic element 2171 is connected to the inner wall of the receiving cavity, and the second end is connected to the first end of the second wedge block 2172. The second end of the second wedge block 2172 has an inclined surface, which is set upwards so that the downward movement of the connecting ball 2232 can push the second wedge block 2172 to move. The second wedge block 2172 is used to lock the connecting ball 2232. When the connecting ball 2232 is placed into the arc-shaped slot 2161, it will push the second wedge block 2172 to compress the second elastic element 2171. When the connecting ball 2232 reaches the appropriate position, the second wedge block 2172 pops out under the action of the second elastic element 2171 and locks the connecting ball 2232.
[0056] like Figure 3 , Figure 9 and Figure 11 As shown, the third locking mechanism 217 also includes a limiting member 2173. The supporting platform 216 is provided with a first limiting hole 2162, and a first magnetic attractor is provided at the bottom of the first limiting hole 2162. The mounting plate 222 is provided with a second limiting hole 2221 that extends vertically through the plate. The second limiting hole 2221 is used to align and cooperate with the first limiting hole 2162. The lower end of the limiting member 2173 is provided with a second magnetic attractor 2174. The limiting member 2173 is used to pass through the first limiting hole 2162 and the second limiting hole 2221. The second magnetic attractor 2174 is used to attract the first magnetic attractor. The limiting member 2173 is used to restrict the rotation of the functional component 221 relative to the supporting platform 216, ensuring the stability of the installation of the functional component 221.
[0057] like Figure 3 and Figure 11As shown, the mounting plate 222 and the third locking mechanism 217 can be correspondingly set with the functional component 221, so that the functional component 221 can be connected to the support platform 216 through the mounting plate 222, the third locking mechanism 217, and the support platform 216. However, the cooperation method between different functional components 221 and the connecting frame 21 can also be different. For example, in this embodiment, there are three support components 215. Two of the support components 215 include a support frame 2151 for external support and a support frame 2152 for supporting the functional component 221. One end of the support frame 2151 is connected to the connecting frame 21, and the other end is connected to the support platform 216. The support frame 2152 is set on the support frame 2151 and is located below the support platform 216. The third support component 215 is a rod-shaped structure, with one end connected to the connecting frame 21 and the other end provided with the support platform 216. CRRT, ventilator, ECMO, and support platform 216 are arranged in a one-to-one correspondence. The first support member 215 has a first support frame 2152, and the second support member 215 has two support frames 2152. The defibrillator monitor, power supply, and infusion unit correspond one-to-one with the support frame 2152, and the power supply and CRRT are located on the same support member 215. The support member 215 also includes a support piece, and the oxygen cylinder is located inside the support piece. This layout makes the installation and use of each functional component 221 more reasonable and facilitates operation and management by medical staff. The functional components 221 can be detachably fixed to the support member 215 via mounting plates 222, or they can be connected to the support platform 216 from the top of the support member 215 via mounting plates 222. The corresponding functional components 221 are fixed to the support frames 2152 below the support platform 216 in other ways. The appropriate fixing method can be selected as needed, and the specific combination method is not limited.
[0058] It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.
[0059] The implementation principle of this embodiment is as follows: The transport device carries various functional mechanisms 2 on a stretcher trolley 1. A first locking mechanism 3 and a third locking mechanism 217 are used to achieve a stable connection between the functional mechanisms 2 and the stretcher trolley 1, as well as between the functional components 221 and the connecting frame 21, ensuring the stability and reliability of the equipment during transport. The combination of various functional components 221 can simulate the function of an ICU when transporting critically ill patients, providing comprehensive life support such as liver and kidney function replacement, ventilation function replacement, cardiopulmonary function replacement, and vital sign monitoring. This reduces the incidence of adverse events during in-hospital transport, achieves seamless transfer of critically ill patients between hospitals at all levels, further shortens treatment time, and improves treatment capabilities.
[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
