Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a multi-person transporter for emergency critical care. Background Technology
[0002] The multi-person transporter for emergency critical care is a professional medical device designed specifically for emergency and intensive care scenarios, used to transport multiple critically ill patients simultaneously. It mainly solves the problem that traditional transport tools are unable to efficiently and safely transport multiple critically ill patients in situations such as public health emergencies and major disasters, and is an important piece of equipment for improving emergency medical rescue capabilities.
[0003] However, in practical applications, existing multi-person transporters for emergency critical care cannot be modularized and cannot be quickly disassembled and assembled. In routine non-emergency situations, or when only a small number of patients need to be transported, this results in a waste of resources and is inconvenient to operate, which is not conducive to improving the practicality of multi-person transporters for emergency critical care.
[0004] Therefore, this application provides a multi-person transporter for emergency critical care to meet the needs. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a multi-person transport device for emergency critical care.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-person transport device for emergency critical care, comprising a transport device body, wherein two transport device bodies are provided, and further comprising: Modular components are placed on both sides of the transfer body. Each modular component includes a snap-fit block connected to one side of the transfer body and a snap-fit plate that matches the snap-fit block connected to the other side of the transfer body. The two transfer bodies are snapped together by the snap-fit block and the snap-fit plate. A fixing component is placed on top of the modular component and is used to reinforce the connection between the snap-fit block and the snap-fit plate. The fixing component includes a fixing groove formed in the snap-fit block and the snap-fit plate, and a fixing pin is inserted into the fixing groove.
[0007] Furthermore, a guide slope is provided on the side of the snap-fit plate near the transfer device body.
[0008] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the rapid stacking of the snap-fit blocks and snap-fit plates, which helps to further improve assembly efficiency.
[0009] Furthermore, one end of the fixing pin is connected to a limiting block, and an annular limiting groove is provided on the side of the snap-fit plate near the limiting block. The fixing pin is snapped into the snap-fit plate through the limiting block and the annular limiting groove.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the limiting block is engaged with the temporal part of the annular limiting groove, thereby fixing the fixing pin to the engaging block and the engaging plate, preventing the fixing pin from accidentally falling off and causing the connection to become loose.
[0011] Furthermore, an anti-slip pad is attached to the top of the fixing pin.
[0012] The beneficial effect of adopting the above-mentioned further solution is that it increases the friction between the fixing pin and the hand, making it easier to apply force when rotating the fixing pin.
[0013] Furthermore, the bottom end of the fixing pin is connected to a limiting plate, and the fixing pin is engaged with the snap-fit plate through the limiting plate.
[0014] The beneficial effect of adopting the above-mentioned further solution is that when the fixing pin slides on the snap-fit plate, the limiting plate limits the maximum movement distance of the fixing pin, preventing the fixing pin from separating from the snap-fit plate and causing the fixing pin to be lost.
[0015] Furthermore, the snap-fit plate has a slot that matches the limiting block, and the limiting block is slidably connected to the snap-fit plate through the slot.
[0016] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the synchronous movement of the limiting block when the fixing pin moves, and prevents the fixing pin from being stuck inside the snap-fit plate by the limiting block.
[0017] Furthermore, the limiting block is provided with an anti-slip coating.
[0018] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the limiting block remains stable inside the annular limiting groove, which is conducive to improving the stability of the connection between the fixing pin and the snap-fit plate.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. By setting up modular components, when one transporter body is pushed to move to another, the snap-fit block will snap into the snap-fit plate, thereby realizing the quick assembly of the two. This gives the transporter body modular characteristics, solving the problem that the inability to achieve modularity and quick disassembly and assembly not only leads to resource waste and inconvenience in daily non-emergency situations or when only a small number of patients need to be transported. This helps to improve the practicality of multi-person transporters for emergency critical care.
[0020] 2. By setting a fixing component and inserting the fixing pin into the fixing groove, the fixing pin can easily fix the snap-fit block and the snap-fit plate from both sides, which can enhance the firmness of the connection between the snap-fit block and the snap-fit plate, thereby ensuring the stability of the transfer device body after connection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a multi-person transport device for emergency critical care, including a transport device body 1, of which two transport device bodies 1 are provided, and further including: like Figures 1-2 As shown, modular component 2 is placed on both sides of the transfer body 1. Modular component 2 includes a snap-fit block 21 connected to one side of the transfer body 1 and a snap-fit plate 22 that matches the snap-fit block 21 connected to the other side of the transfer body 1. The two transfer bodies 1 are snapped together by the snap-fit block 21 and the snap-fit plate 22. like Figures 1-2 As shown, the fixing component 3 is placed on top of the modular component 2 and is used to reinforce the connection between the snap-fit block 21 and the snap-fit plate 22. The fixing component 3 includes a fixing groove 32 formed on the snap-fit block 21 and the snap-fit plate 22. A fixing pin 31 is inserted into the fixing groove 32. By welding the snap-fit block 21 to the transfer body 1 and welding the snap-fit plate 22 to the other side, one transfer body 1 is pushed to move towards the other transfer body 1. The snap-fit block 21 snaps into the inside of the snap-fit plate 22, allowing the two to be quickly assembled, thereby realizing the modularity of the transfer body 1 and solving the problem of The current multi-person transport device for emergency critical care cannot be modularized and cannot be quickly disassembled and assembled. In daily non-emergency situations or when only a small number of patients need to be transported, it will cause resource waste and inconvenience in operation. To improve the practicality of the multi-person transport device for emergency critical care, by opening the fixing groove 32 on both sides of the snap-fit block 21 and the snap-fit plate 22, and inserting the fixing pin 31 into the fixing groove 32, it is convenient for the fixing pin 31 to fix the snap-fit block 21 and the snap-fit plate 22 from both sides, thereby improving the firmness of the connection between the snap-fit block 21 and the snap-fit plate 22 and ensuring the stability of the connection of the transport device body 1.
[0026] Furthermore, such as Figure 3 As shown, a guide slope 23 is provided on the side of the snap-fit plate 22 near the transfer body 1. By pushing the transfer body 1, the guide slope 23 is made to fit against the transfer body 1 on the other side, which facilitates the rapid stacking of the snap-fit block 21 and the snap-fit plate 22, and helps to further improve the assembly efficiency.
[0027] Furthermore, such as Figure 4 As shown, one end of the fixing pin 31 is connected to the limiting block 33. An annular limiting groove 34 is provided on the side of the snap-fit plate 22 near the limiting block 33. The fixing pin 31 is snapped into the snap-fit plate 22 through the limiting block 33 and the annular limiting groove 34. After the limiting block 33 is welded to the fixing pin 31 and the fixing pin 31 is inserted into the inside of the snap-fit plate 22, the fixing pin 31 is rotated so that the limiting block 33 is snapped into the temporal part of the annular limiting groove 34, thereby fixing the fixing pin 31 to the snap-fit block 21 and the snap-fit plate 22, preventing the fixing pin 31 from accidentally falling off and causing the connection to become loose.
[0028] Furthermore, such as Figure 4 As shown, an anti-slip pad 35 is connected to the top of the fixing pin 31. By attaching the anti-slip pad 35 to the top of the fixing pin 31, the friction between the fixing pin 31 and the hand is increased, making it easier to apply force when rotating the fixing pin 31.
[0029] Furthermore, such as Figure 4As shown, the bottom end of the fixing pin 31 is connected to the limiting plate 36. The fixing pin 31 is engaged with the snap-fit plate 22 through the limiting plate 36. By welding the limiting plate 36 onto the fixing pin 31 and opening a snap-fit groove matching the limiting plate 36 on the inner side of the snap-fit plate 22, when the fixing pin 31 slides on the snap-fit plate 22, the limiting plate 36 limits the maximum movement distance of the fixing pin 31, preventing the fixing pin 31 from separating from the snap-fit plate 22 and causing the fixing pin 31 to be lost.
[0030] Furthermore, such as Figure 5 As shown, the snap-fit plate 22 has a slot 38 that matches the limiting block 33. The limiting block 33 is slidably connected to the snap-fit plate 22 through the slot 38. By opening the slot 38 on the snap-fit plate 22 that matches the limiting block 33, it is convenient for the fixing pin 31 to move synchronously with the limiting block 33 when it moves, so as to prevent the fixing pin 31 from being stuck inside the snap-fit plate 22 by the limiting block 33.
[0031] Furthermore, such as Figure 4 As shown, the limiting block 33 is provided with an anti-slip coating 37. The anti-slip coating 37 is sprayed on the limiting block 33, which increases the friction between the limiting block 33 and the annular limiting groove 34, ensuring that the limiting block 33 remains stable inside the annular limiting groove 34, which is beneficial to improving the stability of the connection between the fixing pin 31 and the snap-fit plate 22.
[0032] Working principle: such as Figures 1-5 As shown, first, one transferor body 1 is pushed towards another transferor body 1, and the snap-fit block 21 snaps into the inside of the snap-fit plate 22, allowing the two to be quickly assembled, thus realizing the modularization of the transferor body 1. The fixing pin 31 is inserted into the inside of the fixing groove 32. At this time, the limiting block 33 slides to the inside of the snap-fit plate 22 through the slot 38, and the limiting plate 36 separates from the snap-fit groove on the snap-fit plate 22, making it easier for the fixing pin 31 to fix the snap-fit block 21 and the snap-fit plate 22 from both sides, thereby improving the firmness of the connection between the snap-fit block 21 and the snap-fit plate 22 and ensuring the stability of the connection of the transferor body 1. Then, the fixing pin 31 is rotated by hand, and the anti-slip pad 35 increases the friction between the fixing pin 31 and the hand, making it easier to exert force by hand. Then, the fixing pin 31 drives the limiting block 33 to snap into the inside of the annular limiting groove 34, and the anti-slip coating 37 increases the friction between the limiting block 33 and the annular limiting groove 34, thereby improving the stability of the multi-person transferor for emergency critical care during use.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
