In this embodiment, the structure of the first guide mechanism includes: a guide hole 811 is provided at each of the four corners of the pressure block 8, and four guide pillars 9 are provided on the inner wall of the shell inner plate 61 of the shell 4. Each guide pillar 9 is arranged in a horizontal direction. The four guide pillars 9 on the inner wall of the shell inner plate 61 correspond one-to-one to the four guide holes 811 at the four corners of the pressure block 8. The four guide holes 811 of the pressure block 8 are respectively inserted into the corresponding guide pillars 9 on the inner wall of the shell inner plate 61. The pressure block 8 can only be installed in the inner cavity 41 of the shell 4 in a horizontal direction relative to the shell through the cooperation between the guide holes 811 and the guide pillars 9.

[0050] A locking portion 812 is provided on the side wall of the pressing block 8 and is penetrated through the locking portion entrance and exit 7.

[0051] A locking hole 815 is provided at the top of the pressing block 8, and a first elastic mechanism is provided between the pressing block 8 and the housing 4. The first elastic mechanism enables the pressing block 8 to always have a tendency to translate in the left and right directions to the locking portion 812 and extend from the locking portion entrance 7 to the top of the emergency transport accompanying device 100 placed in the placement area to limit the upper and lower positions of the emergency transport accompanying device 100. In this embodiment, the structure of the first elastic mechanism includes: each guide hole 811 of the pressing block 8 is a stepped hole, and the large-diameter end of the stepped hole is provided at the pressing block away from the placement area. The end face of the pressure block with a small diameter is arranged at the end face of the pressure block close to the placement area. A first spring 11 is sleeved on the outside of each guide column 9. One end of each first spring 11 is against the shell side plate 62 in the shell away from the placement area, and the other end is against the step surface of the corresponding guide hole 811. Each first spring 11 makes the pressure block 8 always have the tendency to move horizontally toward the placement area to the locking part 812 and extend from the locking part entrance and exit 7 to above the emergency transfer accompanying equipment 100 placed in the placement area to limit the upper and lower positions of the emergency transfer accompanying equipment.

[0052] A support plate 10 is fixed in the inner cavity 41 of the shell 4 above the pressure block 8, and a guide hole 101 is provided in the support plate 10 which passes through the support plate 10 from top to bottom. When the pressure block 8 is translated to rest against the inner plate 61 of the shell under the action of the first spring 11, the locking hole 815 of the pressure block 8 just corresponds upward to the guide hole 101 of the support plate 10, and at this time, the locking part 812 of the pressure block 8 just extends from the locking part entrance and exit 7 to above the emergency transfer accompanying equipment 100 placed in the placement area to limit and lock the emergency transfer accompanying equipment.

[0053] The locking and unlocking block 12 is arranged in the mounting opening 5 and can only be installed on the housing 4 in a translational manner relative to the housing through a second guide mechanism. The locking and unlocking block 12 can be moved to a locked position or an unlocked position in the mounting opening 5 through the second guide mechanism; in this embodiment, the mounting opening 5 is a long strip-shaped opening running forward and backward, and the structure of the second guide mechanism includes: a forward and backward sliding groove 121 is respectively provided on the left and right side walls of the locking and unlocking block 12, and two guide bars 13 are fixed inside the housing 4 at the mounting opening 5, which are symmetrically arranged on the left and right sides of the locking and unlocking block 12, each guide bar 13 is arranged in a forward and backward direction, and the two guide bars 13 are respectively slidably embedded in the sliding grooves 121 on both sides of the locking and unlocking block 12, and the locking and unlocking block 12 cannot move up and down relative to the housing but can only move forward and backward relative to the housing 4 in the mounting opening.

[0054] A toggle button 14 located outside the housing 4 is fixed on the top of the locking and unlocking block 12, and a rising notch 16 for inserting the guide block 15 is provided at one end of the bottom of the locking and unlocking block 12. The bottom of the locking and unlocking block 12 adjacent to the rising notch 16 is a flat end surface 122, and the groove bottom surface 161 of the rising notch 16 smoothly transitions to the bottom flat end surface 122 of the locking and unlocking block 12 through the guide slope 162. A guide block 15 and a lock pin 17 are provided below the locking and unlocking block 12. 15 is installed on the upper end of the lock pin 17, the top surface 152 of the guide block 15 is a flat end surface, and the side surface 153 of the guide block close to the unlocking position smoothly transitions to the top surface 152 of the guide block 15 through an inclined surface 151 that gradually tilts upward from the unlocking position to the locking position, and the inclined surface 151 is used to cooperate with the guide inclined surface 162 of the rising notch 16 of the lock unlocking block 12; the lower end of the lock pin 17 is downwardly inserted into the guide hole 101 of the support plate 10, and a second connecting rod is connected between the lock pin 17 and the support plate 10. The second spring 19 ensures that the locking pin 17 always has the tendency to move upward and disengage from the locking hole 815 of the pressure block 8 and enables the guide block 15 to always press upward and tightly contact the locking and unlocking block 12; in this embodiment, the structure of the second elastic mechanism includes: a positioning boss 18 is fixed to the outer wall of the locking pin 17 below the guide block 15, and a second spring 19 is provided between the positioning boss 18 and the support plate 10, and the second spring 19 is sleeved on the locking pin 17, the upper end of the second spring 19 presses against the positioning boss 18, and the lower end of the second spring 19 presses against the support plate 10, so that the second spring 19 ensures that the locking pin 17 always has the tendency to move upward and disengage from the locking hole 815 of the pressure block 8 and enables the guide block 15 to always press upward and tightly contact the locking and unlocking block 12; when the locking and unlocking block 12 is in the unlocking position, the rising notch 16 of the locking and unlocking block 12 just corresponds to the guide block 15 downward, and when the locking and unlocking block 12 is in the locking position, the bottom flat end surface 122 of the locking and unlocking block 12 just corresponds to the guide block 15 downward.

[0055] When the locking and unlocking block 12 is in the unlocking position, the guide block 15 and the locking pin 17 will move together toward the corresponding rising notch 16 upward under the upward elastic force of the second spring 19, so that the locking pin 17 disengages from the locking hole 815 of the pressure block 8 to unlock the pressure block 8. After the pressure block 8 is unlocked, the pressure block 8 is only subjected to the elastic force of the first spring 11. At this time, an external force sufficient to overcome the elasticity of the first spring 11 is applied to the emergency transport accompanying device 100, so that the emergency transport accompanying device 100 can be conveniently placed downward into the bottom plate placement area or taken upward from the bottom plate placement area.

[0056] When the emergency transport accompanying device 100 is placed downwardly in the placement area of the bottom plate 1, and the pressure block 8 is translated under the action of the first spring 11 until its locking portion 812 extends from the locking portion entrance 7 to the lower guide surface 814 of the locking portion 812 and is pressed against the top of the corresponding side casing of the emergency transport accompanying device 100, the lock unlocking block 12 is driven to move from the unlocking position to the locking position by toggling the button 14. In the process of the lock unlocking block 12 moving from the unlocking position to the locking position, the lock unlocking block 12 gradually pushes the guide block 15 and the lock pin 17 downward together through the guide slope 162, so that the lock pin 17 is gradually inserted into the locking hole 815 of the pressing block 8. When the locking and unlocking block 12 moves to the locking position, the locking pin 17 is just inserted into the locking hole 815 of the pressing block 8 and at this time the locking and unlocking block 12 is just moved to its bottom flat end surface 122 to press down on the contact guide block 15, so that the locking pin 17 cannot move up and remains in the locked state of being inserted downward into the locking hole 815 of the pressing block, so that the pressing block 8 keeps its locking part 812 extending from the locking part entrance and exit 7 and buckled on the top of the corresponding side casing of the emergency transport accompanying device 100 to limit the emergency transport accompanying device 100 to the locked state on the base plate 1.

[0057] In this embodiment, a positioning mechanism is provided between the locking and unlocking block 12 and the housing 4, which can assist in positioning the locking and unlocking block 12 when it is moved to the locked position or the unlocked position.

[0058] like Figure 23 As shown, the medical stretcher includes a stretcher body 500 , on which an emergency transport accompanying device fixing structure 600 for mounting and fixing the emergency transport accompanying device 100 is installed.

[0059] The following uses the emergency transport accompanying device as an ECMO host as an example to explain in detail the working principle of the fixed structure of the emergency transport accompanying device:

[0060] In actual application, the bottom plate 1 of the emergency transport accompanying equipment fixing structure 600 is first fixedly installed on the stretcher body 500 of the medical stretcher; then the emergency transport accompanying equipment 100 (ECMO host) is placed in the emergency transport accompanying equipment fixing structure 600, and the emergency transport accompanying equipment 100 is effectively locked and fixed by the emergency transport accompanying equipment fixing structure 600, so that the emergency transport accompanying equipment 100 will not shake on the stretcher during the transportation process.

[0061] The principle of locking and unlocking the emergency transport accompanying device 100 (ECMO host) by the emergency transport accompanying device fixing structure 600 is as follows:

[0062] First, push the toggle button 14 in each locking and unlocking mechanism 400 on the fixing structure 600 of the emergency transport accompanying device to the unlocking position, and simultaneously drive the corresponding locking and unlocking block 12 to move to the unlocking position. When the locking and unlocking block 12 is in the unlocking position, the guide block 15 and the locking pin 17 will move together toward the corresponding rising notch 16 upward under the upward elastic force of the second spring 19, so that the locking pin 17 disengages from the locking hole 815 of the pressure block 8 to unlock the pressure block 8. At this time, the pressure block 8 is only affected by the elastic force of the first spring 11; then move the emergency transport accompanying device 1 (ECMO host) to The lower portion is aligned with the placement area of the base plate and is placed into the placement area of the base plate 1 from top to bottom; during the downward movement of the emergency transport accompanying device 1 (ECMO host), the emergency transport accompanying device 1 (ECMO host) will first contact the upper guide surface 813 of the pressure block locking portion 812 of each locking and unlocking mechanism 400. As the emergency transport accompanying device 1 (ECMO host) continues to move downward, the emergency transport accompanying device 1 (ECMO host) will use the upper guide surface 813 to enable the pressure blocks of each locking and unlocking mechanism 400 to overcome the elastic force of the corresponding first spring 11 and move toward the inner cavity of the corresponding shell 4, that is, the pressure block 8 in the unlocked state will not hinder the emergency transport accompanying device 100 (ECMO host) from moving downward into the placement area of the base plate.

[0063] When the positioning holes 200 at the bottom of the emergency transport accompanying device 1 (ECMO host) are aligned downward and inserted into the corresponding positioning columns 26 in the bottom plate installation area and are completely placed in the installation area of the bottom plate 1, the pressing block 8 is exactly aligned with the top of the corresponding side casing of the emergency transport accompanying device 1 (ECMO host). At this time, the pressing block 8 will be translated toward the emergency transport accompanying device under the action of the first spring 11 until it rests against the inner side plate 61 of the shell. At this time, the locking portion 812 of the pressing block 8 is just extended from the locking portion entrance 7 to the lower guide surface 814 of the locking portion 812 and is pressed downward on the top of the corresponding side casing of the emergency transport accompanying device 100 (ECMO host); then the toggle buttons 14 of each locking and unlocking mechanism 400 are moved from the unlocking position to the locking position, synchronously driving the locking and unlocking block 12 to move from the unlocking position to the locking position. In the process of the locking and unlocking block 12 moving from the unlocking position to the locking position, the locking and unlocking block 12 is matched with the inclined surface 151 of the guide block 15 through the guiding inclined surface 162. When the locking and unlocking block 12 moves to the locked position, the locking pin 17 is just inserted into the locking hole 815 of the pressing block 8 and the locking and unlocking block 12 is just moved to the point where its bottom flat end surface 122 presses down and contacts the flat end surface of the top surface 152 of the guide block 15, so that the locking pin 17 cannot move upward and remains in the locked state of being inserted downward into the locking hole 815 of the pressing block, so that the pressing block 8 keeps its locking portion 812 extending from the locking portion entrance 7 and pressing downward on the top of the corresponding side casing of the emergency transport accompanying device 100 (ECMO host) to limit and lock the emergency transport accompanying device 100 to the locked state on the bottom plate 1 (ECMO host), thereby completing the locking and fixing of the emergency transport accompanying device 100 (ECMO host) and firmly installing the emergency transport accompanying device 100 (ECMO host) on the stretcher body 500 of the medical stretcher.

[0064] When the emergency transport accompanying device 100 (ECMO host) needs to be removed from the emergency transport accompanying device fixing structure 600, the toggle button 14 in each locking and unlocking mechanism 400 on the emergency transport accompanying device fixing structure 600 is toggled from the locked position to the unlocked position, and the corresponding locking and unlocking block 12 is simultaneously driven to move from the locked position to the unlocked position. When the locking and unlocking block 12 is in the unlocked position, the rising notch 16 of the locking and unlocking block 12 corresponds to the guide block 15 downward. At this time, the guide block 15 and the locking pin 17 have upward movement space. Under the upward elastic force of the second spring 19, the guide block 15 and the locking pin 17 will move together to the corresponding rising notch 16 upward, so that The locking pin 17 disengages from the locking hole 815 of the pressure block 8 to unlock the pressure block 8. At this time, the pressure block 8 is only acted upon by the elastic force of the first spring 11. Then, the emergency transport accompanying device 1 (ECMO host) is moved upward. During the upward movement of the emergency transport accompanying device 1 (ECMO host), the emergency transport accompanying device 1 (ECMO host) will first contact the lower guide surface 814 of the pressure block locking portion 812 of each locking and unlocking mechanism 400. As the emergency transport accompanying device 1 (ECMO host) continues to move upward, the emergency transport accompanying device 1 will use the lower guide surface 814 to enable the pressure blocks of each locking and unlocking mechanism 400 to overcome the elastic force of the corresponding first spring 11 and move toward the inner cavity 41 of the corresponding shell 4. That is, the pressure block 8 in the unlocked state will not hinder the emergency transport accompanying device from moving away from the placement area of the bottom plate until the emergency transport accompanying device 100 is removed from the emergency transport accompanying device fixing structure 600.

[0065] The advantages of the present invention are: (1) it can quickly lock and fix the emergency transfer accompanying equipment, so that the emergency transfer accompanying equipment will not shake on the stretcher during the transportation process with the medical stretcher, effectively avoiding the loosening and falling of related connecting pipes and the falling of the emergency transfer accompanying equipment from the stretcher due to the shaking of the emergency transfer accompanying equipment, which is conducive to the safe transportation of patients and is suitable for the use conditions of the emergency transfer accompanying equipment; (2) when the emergency transfer accompanying equipment needs to be taken away, the emergency transfer accompanying equipment can be quickly unlocked, and the locking and unlocking operations are very convenient; (3) the emergency transfer accompanying equipment is installed inside the emergency transfer accompanying equipment fixing structure, and the emergency transfer accompanying equipment fixing structure can protect the emergency transfer accompanying equipment, avoiding the emergency transfer accompanying equipment from being directly hit by other equipment during the transportation process, further protecting the emergency transfer accompanying equipment, and is suitable for the use conditions of the emergency transfer accompanying equipment, which is conducive to the safe transportation of patients.
