Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to an extracorporeal membrane oxygenation equipment transport device. Background Art

[0002] Extracorporeal membrane oxygenation (ECMO) is mainly used to provide continuous extracorporeal respiration and circulation to maintain the life of patients with severe cardiopulmonary failure. Therefore, the ECMO device cannot be removed when the patient's cardiopulmonary function has not recovered to the lowest level. Patients with severe cardiopulmonary failure are in a serious condition and usually need to be transferred to a higher-level hospital or a hospital with a stronger department for treatment. Therefore, when these patients use the ECMO device, the ECMO device needs to be transported to the receiving hospital by ambulance together with the patient to ensure that the patient will not have an accident due to respiratory obstruction during the transfer process.

[0003] Because blood needs to be drawn from the veins, then oxygenated through the membrane lung, carbon dioxide is discharged, and then the oxygenated blood is input into the patient's body, the extracorporeal membrane oxygenation device includes not only the host but also a power pump, multiple vascular cannulas connecting the host to the patient, and a patient status monitoring system. Current extracorporeal membrane oxygenation devices are usually placed on a cart so that they can be moved with the patient. However, since there is no connection between the cart and the transport bed where the patient is located, relative movement between the cart and the transport bed is likely to occur when the patient is moved, causing the pipeline between the patient and the extracorporeal membrane oxygenation device or the data cable of the monitoring system to be pulled, which can cause the pipeline to loosen or even fall off in severe cases, which can cause blood leakage and the extracorporeal membrane oxygenation device to be unable to provide extracorporeal respiratory support for the patient, resulting in serious consequences.

[0004] Later, a multifunctional ECMO equipment transport vehicle as disclosed in the patent with application number CN202410358448.4 appeared, including a bed board and upper running wheels at the bottom thereof, the upper running wheels are arranged in pairs, with no less than two pairs of upper running wheels, one end of the bed board is provided with a storage and retrieval U-shaped frame, and U-shaped slide rails are symmetrically arranged on the upper sides of the bed board and the storage and retrieval U-shaped frame, one end of the U-shaped slide rail is arranged on the front end upper wall of the bed board, and the other end of the U-shaped slide rail is arranged on the inner bottom wall of the storage and retrieval U-shaped frame, a placing and moving component is slidingly provided on the U-shaped slide rail, a self-protection storage and retrieval component is provided on the storage and retrieval U-shaped frame, and walking components are symmetrically arranged on the front and rear of the lower part of the bed board, and a self-folding locking component is provided at the front of each group of walking components.

[0005] The above-mentioned transfer vehicle can directly install the extracorporeal membrane oxygenation device on the U-shaped slide rails on both sides of the bed board. As the transfer vehicle moves at the same time, the extracorporeal membrane oxygenation device can also be moved to the position with the self-protection storage and access component during use. The extracorporeal membrane oxygenation device is protected by the storage and access U-shaped frame and the self-protection storage and access component, and it can also not cause obstacles when the patient is transferred to the transfer bed. However, it is found in actual use that when the extracorporeal membrane oxygenation device is moved to the position of the self-protection storage and access component, the placement and moving component needs to be flipped 90°. At this time, the extracorporeal membrane oxygenation device placed in the placement and moving component will also be flipped 90°. In this process, the risk of loosening and falling off of the pipeline between the extracorporeal membrane oxygenation device and the patient will undoubtedly increase, and the pipeline is easily pulled or bent at one end close to the extracorporeal membrane oxygenation device during flipping, thereby reducing the inner diameter of the pipeline for blood circulation, resulting in a decrease in the effect of providing extracorporeal respiratory support, affecting the patient's life safety. Summary of the invention

[0006] The present invention is intended to provide an extracorporeal membrane oxygenation equipment transport device to solve the problem that excessive posture adjustment of the extracorporeal membrane oxygenation equipment may easily lead to loosening of the pipeline.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an extracorporeal membrane oxygenation equipment transport device, comprising a bed body, a walking unit, a mounting unit and a guide unit, wherein an upper leg is fixed under the bed body; the walking unit comprises a support plate and a plurality of lower legs, each of which is provided with a roller at the bottom, the lower legs are mounted on the support plate, a first guide groove is provided on the support plate along the length direction of the bed body, the bottom of the upper leg is located in the first guide groove and can slide along the first guide groove, and at least one upper leg is detachably connected to the support plate;

[0008] The mounting unit is located between the bed and the support plate, and includes a mounting frame and an observation plate. The mounting frame is connected to the bed, and a mounting space is provided inside the mounting frame. An opening is provided on the mounting frame, and the observation plate is opposite to the opening and is used to close the opening. An observation window is provided on the observation plate.

[0009] The guide unit includes a guide rail and a pulling assembly. The guide rail is provided with a second guide groove. The extension line of the second guide groove coincides with the first guide groove. The pulling assembly includes a walking member and a pulling rod. The walking member drives the pulling rod to move along the length direction of the second guide groove. The pulling rod is detachably connected with a hook, and the hook is connected to at least one of the bed body, the upper leg and the mounting frame.

[0010] The beneficial effects of this program are:

[0011] 1. When the transfer device in this solution is used, the extracorporeal membrane oxygenation device is placed on the mounting frame. Since the mounting frame is located under the bed, the patient will not be blocked by the extracorporeal membrane oxygenation device when being transferred to the bed. Therefore, it is not necessary to move the extracorporeal membrane oxygenation device before transferring the patient. Secondly, the bed can shield the extracorporeal membrane oxygenation device to prevent external objects from falling on the extracorporeal membrane oxygenation device. Therefore, it is not necessary to move the extracorporeal membrane oxygenation device to another position for protection during use. Therefore, this solution can reduce the movement of the extracorporeal membrane oxygenation device, prevent the pipelines on the extracorporeal membrane oxygenation device from loosening and falling off, and increase the safety of transfer.

[0012] 2. When transferring the patient from the ward to the ambulance by the transfer device in this solution or when transferring the patient from the ambulance to the ward at the receiving hospital, the accompanying medical staff can clearly see the screen of the extracorporeal membrane oxygenation device through the observation window, understand the patient's condition at any time, and provide timely treatment in the case of hypoxia.

[0013] 3. The guide unit in this solution is installed on the ambulance. When the patient needs to be transferred to the ambulance, the bed and the upper legs can be pulled by pulling the assembly, so that the upper legs slide from the first guide groove into the second guide groove, thereby directly pulling the bed from the walking unit into the ambulance. Compared with manual movement, the pulling of the guide unit in this solution is more stable, and the transfer device with the extracorporeal membrane oxygenation equipment is heavier. This solution can also reduce the weight of medical staff by pulling through the guide unit.

[0014] Compared with folding the walking unit and then putting them into the ambulance together, this solution disassembles the bed board and the walking unit, slides the bed board into the ambulance alone, and then puts the walking unit into the ambulance, which can avoid the vibration of the bed board when folding the walking unit, causing vibration of the patient and the extracorporeal membrane oxygenation equipment, and further prevents the pipeline from loosening and falling off.

[0015] Furthermore, the mounting unit is located at one end of the bed close to the patient's head, the observation board can rotate relative to the bed, and the observation board is provided with a reflecting surface that can face the inside of the mounting frame and the upper end can be tilted toward the side close to the bed.

[0016] The beneficial effects of this solution are as follows: the observation board in this solution can be flipped, and the reflective surface can be rotated to face the screen direction of the extracorporeal membrane oxygenation device. At this time, the medical staff who push the transfer device to move can see the numbers on the screen through the reflective surface, without waiting for the values ​​to drop below the safe value and start treatment when the monitoring unit sounds an alarm. Compared with directly exposing the screen of the extracorporeal membrane oxygenation device to the outside, this solution has a better protection effect on the extracorporeal membrane oxygenation device; compared with setting a screen connected to the host of the extracorporeal membrane oxygenation device at a position such as a bed or setting a camera to shoot the screen of the extracorporeal membrane oxygenation device, the use of the reflective surface for observation in this solution does not require the use of a power source, making the transfer device lower in cost and lighter in weight. Secondly, the incident angle can be changed by rotating the reflective surface, which is more conducive to observation by medical staff in different positions and different heights, and the operation is simple.

[0017] Furthermore, the opening is located at the top of the lifting frame, the observation plate is arranged on the bed body and hinged to the bed body, the mounting frame includes a bracket and a lifting frame, the bracket is connected to the bed body, and the lifting frame is located on the bracket; a horizontal top plate is provided in the lifting frame, and the top plate and the lifting frame slide together vertically, an upper top block and a screw are provided below the top plate, the upper top block is fixed to the top plate, and the upper top block and the screw form a ball screw structure, and the lower end of the screw passes through the lifting frame and is connected to a U-shaped handle.

[0018] The beneficial effect of this solution is that the screw can be driven to rotate by turning the handle, thereby controlling the bottom plate to slide vertically, and fine-tuning the height of the extracorporeal membrane oxygenation device, so that it is more convenient to view the value displayed by the extracorporeal membrane oxygenation device through the observation window.

[0019] Furthermore, the observation plate is in the shape of a transparent plate, and a reflecting plate is slidably matched on the observation window, and the side of the reflecting plate away from the observation window is a reflecting surface.

[0020] The beneficial effect of this solution is that when the medical staff is located at the head position of the patient, the screen of the extracorporeal membrane oxygenation device can be directly seen through the transparent observation window when the opening of the observation window is closed.

[0021] Furthermore, the opening is located on the front side of the mounting frame, and a sliding seat is slidably connected to the mounting frame, and the sliding direction of the sliding seat is parallel to the length direction of the bed; the observation plate is hinged to the sliding seat, and the reflecting surface is located on the side wall of the observation plate away from the opening.

[0022] The beneficial effects of this solution are as follows: the side of the mounting frame located at the patient's head is the front side, and the side of the mounting frame located at the patient's feet is the rear side. The extracorporeal membrane oxygenation device in this solution is placed close to the patient's head. On the one hand, the pipeline connecting the extracorporeal membrane oxygenation device and the patient can be shorter; on the other hand, when pushing the transfer device, medical staff will pay more attention to the ground in front of the patient and on both sides of the head, surrounding pedestrians, objects, etc. due to long-term habits, so as to avoid the front end of the transfer device from colliding with them. Therefore, this solution can also avoid the extracorporeal membrane oxygenation device from colliding with surrounding pedestrians, etc., further reduce the vibration received by the extracorporeal membrane oxygenation device, and improve the safety of transfer.

[0023] Furthermore, the walking unit also includes two baffles, which include a horizontal portion and a vertical portion distributed in an L shape, the horizontal portion being fixedly connected to the vertical portion, the horizontal portion being located between the support plate and the upper leg and being against the upper leg, the vertical portion being located to the side of the upper leg and being against the upper leg, and the connecting parts of the horizontal portion and the vertical portion of the two baffles are both rotatably coordinated with the support plate.

[0024] The beneficial effects of this solution are as follows: the baffles are located on both sides of the extracorporeal membrane oxygenation device to prevent foreign objects from colliding with the extracorporeal membrane oxygenation device from both sides, and further prevent damage to the extracorporeal membrane oxygenation device or loosening of the pipeline. When the walking unit is placed in an ambulance, the baffles in this solution can be folded, thereby reducing the space required for the walking unit. Secondly, a larger safety space is formed between the two baffles, and objects in the safety space are not easily hit by objects flying in from the front and both sides. Therefore, this solution can also place other equipment or medicines, oxygen bags, etc. that maintain the patient's vital signs in the safety space to protect these equipment, objects, etc.

[0025] Furthermore, two support plates are provided, and the two support plates are respectively opposite to the lower legs located on both sides of the bed body; connecting rods are provided at the head and foot of the bed body, and the two ends of the connecting rods are respectively detachably connected to the two support plates.

[0026] The beneficial effect of this solution is that the two support plates can be separated by removing the connecting rod, thereby further reducing the space occupied by the walking assembly and facilitating its placement in the ambulance.

[0027] Furthermore, a fixing plate is fixed to the bottom of at least one upper leg, a socket is provided on the fixing plate, the first guide groove and the second guide groove are both provided with fixing holes that can be aligned with the through hole, and a positioning rod that can be inserted into the fixing hole is slidably fitted in the socket.

[0028] The beneficial effect of this solution is that the upper support leg in this solution can be simply and quickly connected to the walking unit and the guide rail through the positioning rod, so that when the transfer device is in the ambulance, it will not slip when the ambulance turns quickly or brakes, thereby avoiding large vibrations of the patient and the extracorporeal membrane oxygenation equipment due to the collision of the transfer device with surrounding objects.

A second guide groove is provided on the guide rail 6. In actual implementation, the length of the lower leg 41 is set according to the height of the ambulance, so that the bottom of the second guide groove is equal to the bottom of the first guide groove, and the extension of the two second guide grooves in the length direction overlaps with the two first guide grooves respectively, so that the upper leg 12 can slide from the first guide groove to the second guide groove when sliding.

[0045] The pulling assembly includes a walking member 8 and a pull rod 7. The walking member 8 is installed at the left end of the guide rail 6 by bolts. The pull rod 7 is transversely arranged between the two guide rails 6, and the guide rail 6 is provided with a strip groove 61 on the side facing the other guide rail 6. The two ends of the pull rod 7 respectively penetrate the two strip grooves 61, and the sliding of the pull rod 7 is guided by the strip grooves 61. The walking member 8 adopts a motor, and the motor is connected to a winding roller 81 through a flange. The winding roller 81 is transversely arranged and extends into two second guide grooves respectively. Sliding seats 71 are slidably arranged in the two second guide grooves, and the two ends of the pull rod 7 are welded to the two sliding seats 71 respectively; a cable 72 is connected to the pull rod 7, one end of the cable 72 is wound around the winding roller 81, and the other end is connected to the sliding seat 71. A hook is hinged on the bracket. In actual implementation, the length of the hook is determined according to the distance between the pull rod 7 and the rear end of the ambulance, and it is sufficient to ensure that the hook can be connected to the pull rod 7.

[0046] The specific implementation process is as follows:

[0047] The extracorporeal membrane oxygenation device in this embodiment is located in the lifting frame and moves synchronously with the transfer device and the patient. During the patient transfer process, if the medical staff responsible for paying attention to the patient's oxygenation status is close to the observation board 2, the screen of the extracorporeal membrane oxygenation device can be directly viewed through the observation board 2, and the patient's oxygenation status can be timely understood, and timely treatment can be performed when the patient's value decreases. When the responsible medical staff is at a certain distance from the observation board 2, the observation board 2 is flipped so that the reflective surface is opposite to the screen of the extracorporeal membrane oxygenation device, and the flip angle of the observation board 2 is determined according to the height of the medical staff and the distance from the observation board 2, so that the medical staff can see the screen through the reflective board 21. In actual implementation, a reflective surface can also be added to the lifting frame 5, and the screen of the extracorporeal membrane oxygenation device can be observed through the reflection of the two reflective surfaces. Compared with only setting one reflective surface, after two reflections, the object will not be reversed, and the observation of the value displayed on the screen of the extracorporeal membrane oxygenation device is more in line with daily viewing habits.

[0048] When the patient needs to be transferred to the ambulance, the first guide groove is aligned with the second guide groove, and then connected to the pull rod 7 through the hook, and finally the walking member 8 is started, the positioning rod 14 is loosened, and the walking member 8 drives the pull rod 7 to slide along the second guide groove when the cable 72 is rolled up, and the upper leg 12, the bed board and the installation unit are automatically pulled into the ambulance. After the upper leg 12 is completely separated from the support plate 4, the connecting rod 42 and the remaining positioning rod 14 are taken out to close the baffle 3 and the two support plates 4, so as to facilitate the placement of the walking unit into the ambulance. When the bed body 1 is moved into the ambulance, the walking member 8 is closed, and the positioning rod 14 is inserted into the aligned jack and fixing hole to position the bed body 1 to prevent the bed body 1 from moving in the ambulance.

[0049] In actual implementation, a ball or roller may be provided at the bottom of the upper leg 12 to reduce the friction between the upper leg 12 and the first guide groove and the second guide groove, so that the bed body 1 is easier to be pulled into the ambulance.

[0050] When the bed 1 needs to be taken out of the ambulance, first connect the connecting rod 42 to the two support rods, flip the baffle 3 in the opposite direction, rotate the vertical part 32 back to the vertical state, then connect the horizontal part 31 to the support part through the positioning rod 14, and then move the walking unit to align the first guide groove with the second guide groove, remove the positioning rod 14 connecting the upper leg 12 to the guide rail 6, and then slide the bed 1 back onto the support plate 4.

[0051] Example 2

[0052] On the basis of Example 1, Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the opening in this embodiment is located on the left side wall of the lifting frame 5, and the extracorporeal membrane oxygenation device is placed into the lifting frame 5 from the left. A guide block 92 is welded on the bottom plate 9, and the guide block 92 extends along the length direction of the bed body 1. The lower part of the observation plate 2 is hinged with a sliding rod 23, and the right end of the sliding rod 23 extends into the guide block 92 and cooperates with the guide block 92 with a small gap, ensuring that the sliding rod 23 can slide relative to the guide block 92.

[0053] Example 3

[0054] On the basis of Example 2, Figure 6 As shown, the bottom plate 9 in this embodiment extends rightward to the right end of the bed body 1, and at this time the bottom plate 9 can be used to place other equipment during the transportation process.
