A smart transport device for emergency treatment of critically ill patients

Abstract

This invention relates to an intelligent transport device for critically ill patients, belonging to the field of medical transport technology. It addresses the technical problem of insufficient stability in existing transport devices during the transport of lying patients. The device utilizes a limiting post beneath the patient that moves downwards under gravity. Under the action of a piston plate, the pressure inside the pressure chamber increases, causing the limiting post around the patient to rise and enclose the patient. When the limiting post reaches its maximum position, the piston plate pushes the valve plate upwards, aligning the second through-hole with the through-groove. At this point, the third connecting groove also aligns with the through-groove, ultimately connecting the pressure chamber to the cavity. The high pressure causes gas to flow through the longitudinal groove, the first through-hole, and the connecting pipe, causing the expansion ball to expand and provide better envelopment and cushioning for the patient. This effectively prevents the patient from swaying and shifting during transport, while also providing better cushioning protection. The device is easy to operate.

Description

Technical Field

[0001] This invention relates to the field of medical transport technology, and in particular to an intelligent transport device for emergency treatment of critically ill patients. Background Technology

[0002] Transport beds are essential equipment in hospitals. When receiving patients, they are often used for transportation. During the transportation process, if the patient's vital signs change rapidly, the speed of transportation directly determines whether the patient can receive the best treatment time.

[0003] The existing transport method involves placing the patient on a stretcher or transport bed and using a vehicle for transportation. After the vehicle arrives at the hospital, the patient still needs to be transported to the emergency room of different departments via a transport bed. During this process, due to the time constraints, the stability of the transport cannot be guaranteed. The patient is prone to swaying and displacement on the side, which poses a risk of falling off the bed and also increases the risk of pressing on already injured areas during transport.

[0004] To address the aforementioned problems, an intelligent transport device for emergency treatment of critically ill patients is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent transport device for emergency treatment of critically ill patients, which solves the problem of insufficient stability of existing transport devices in the background art during the transportation of lying patients.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent transport device for emergency treatment of critically ill patients, comprising a mobile base and a mattress body mounted on the mobile base. The mattress body is provided with a movable groove, and a limiting post is slidably connected inside the movable groove. Expansion balls are evenly distributed on both sides of the limiting post. When a patient lies on the limiting post and presses it down, the limiting post located at the outer edge of the patient protrudes upward to wrap and limit the patient's outer side. The expansion balls are used to cushion the patient and provide better wrapping after the limiting post protrudes and expands.

[0007] The mattress body has a pressure chamber inside and a first connecting groove inside, which is connected to the pressure chamber. An installation groove is located at the end of the first connecting groove inside the mattress body. The first connecting groove and the installation groove are connected to the upper part of the movable groove inside the mattress body. A second connecting groove is located below the movable groove inside the mattress body and is connected to the first connecting groove. A connecting mechanism is located inside the installation groove, and the connecting mechanism corresponds to the limiting stop post. The connecting mechanism is used to control the connection state between the pressure chamber and the expansion ball.

[0008] Furthermore, the movable groove array is distributed inside the mattress body, and the top of the movable groove opens upwards. The diameter of the limiting stop post corresponds to the diameter of the opening at the top of the movable groove. A piston plate is fixedly connected to the bottom of the limiting stop post, and the diameter of the piston plate corresponds to the diameter of the movable groove.

[0009] Furthermore, the limiting stop post is provided with airbag grooves on both sides to accommodate the expansion ball, and the airbag grooves are semi-circular, with half of the expansion ball glued to the airbag groove.

[0010] Furthermore, a transverse groove is provided between the corresponding airbag grooves on both sides, and a chamber is provided below the interior of the limiting column. The chamber is connected to the transverse groove through a longitudinal groove.

[0011] Furthermore, a connecting pipe is provided between the corresponding expansion balls on both sides, and a first through hole is provided on the connecting pipe, which is vertically connected and corresponds to the longitudinal groove.

[0012] Furthermore, a spring groove is provided inside the main body of the mattress below the movable groove, and a first spring is installed in the spring groove. The top of the first spring is fixedly connected to the piston plate.

[0013] Furthermore, the connecting mechanism includes a valve seat installed inside the mounting groove, a limiting groove extending vertically through the valve seat, a valve plate slidably connected within the limiting groove, one end of the valve plate corresponding to a piston plate, and a second spring between the top of the valve plate and the inner wall of the top of the mounting groove.

[0014] Furthermore, the valve seat is provided with a transverse through groove, and the valve plate is provided with a second through hole, which corresponds to the through groove. The two ends of the through groove are respectively connected to the first connecting groove and the movable groove.

[0015] Furthermore, a third connecting groove is provided inside the piston plate. One end of the third connecting groove is connected to the chamber, and the other end of the third connecting groove extends to the outside of the piston plate. The third connecting groove corresponds to the through groove on the valve seat.

[0016] Furthermore, sliding grooves are provided on both sides below the limiting stop post, and locking plates are slidably connected in the sliding grooves. The locking plate is fixedly connected to the limiting plate at one end inside the cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention provides an intelligent transport device for critically ill patients. After the patient lies down, the limiting posts under the patient move downwards under gravity. Under the action of the piston plate, the pressure inside the pressure chamber increases, causing the limiting posts around the patient to rise and wrap around the patient. When the limiting posts rise to their maximum position, the piston plate pushes the valve plate upwards, causing the second through hole to align with the through groove. At this time, the third connecting groove aligns with the through groove, and the pressure chamber finally connects with the cavity. The high pressure state causes gas to pass through the longitudinal groove, the first through hole, and the connecting pipe, causing the expansion ball to expand and provide better wrapping and cushioning for the patient. This effectively prevents the patient from swaying and shifting during transport, while providing better cushioning protection. The device is simple to operate and highly intelligent.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To address the technical problem of insufficient stability of existing transport equipment during the transport of lying patients, such as... Figures 1-9 As shown, the following preferred technical solutions are provided:

[0031] An intelligent transport device for critically ill patients includes a mobile base 1 and a mattress body 2 mounted on the mobile base 1. The mattress body 2 has a movable groove 3, with a limiting post 4 slidably connected inside the movable groove 3. Inflatable balls 5 are evenly distributed on both sides of the limiting post 4. When a patient lies on the limiting post 4 and is pressed down, the limiting post 4 located at the outer edge of the patient protrudes upwards to wrap and limit the patient's movement. The inflatable balls 5 expand after the limiting post 4 protrudes, providing cushioning and better wrapping for the patient. A pressure chamber 21 is provided inside the mattress body 2. The interior is also provided with a first connecting groove 23, and the pressure chamber 21 is connected to the first connecting groove 23. The mattress body 2 is provided with an installation groove 25 at the end of the first connecting groove 23. The first connecting groove 23 and the installation groove 25 are connected to the upper interior of the movable groove 3. The mattress body 2 is provided with a second connecting groove 24 at the bottom of the movable groove 3, and the second connecting groove 24 is connected to the first connecting groove 23. The installation groove 25 is provided with a connecting mechanism 6, and the connecting mechanism 6 corresponds to the limiting stop 4. The connecting mechanism 6 is used to control the connection state between the pressure chamber 21 and the expansion ball 5.

[0032] The movable grooves 3 are arranged in an array inside the mattress body 2, and the top of the movable grooves 3 opens upward. The diameter of the limiting stop 4 corresponds to the diameter of the top opening of the movable groove 3. The bottom of the limiting stop 4 is fixedly connected to a piston plate 43, and the diameter of the piston plate 43 corresponds to the diameter of the movable groove 3.

[0033] The limiting post 4 has air bladder grooves 41 on both sides to accommodate the expansion ball 5. The air bladder grooves 41 are semi-circular. Half of the expansion ball 5 is glued to the air bladder groove 41. When the expansion ball 5 inflates, it protrudes outward. When the expansion ball 5 contracts, it can be accommodated inside the air bladder groove 41, which facilitates the sliding of the limiting post 4 inside the movable groove 3.

[0034] A transverse groove 411 is provided between the corresponding airbag grooves 41 on both sides. A chamber 42 is provided at the bottom of the limiting column 4. The chamber 42 is connected to the transverse groove 411 through a longitudinal groove 412. A connecting pipe 51 is provided between the corresponding expansion balls 5 on both sides. A first through hole 52 is provided on the connecting pipe 51, and the first through hole 52 corresponds to the longitudinal groove 412.

[0035] Inside the mattress body 2, below the movable groove 3, there is a spring groove 22. A first spring 44 is installed in the spring groove 22. The top of the first spring 44 is fixedly connected to the piston plate 43. Under the action of the first spring 44, the distance from the limit stop 4 to the top of the movable base 1 is half the length of the limit stop 4. When the patient lies on the movable base 1, the limit stop 4 located below the patient compresses the first spring 44 inside the movable groove 3 and moves downward until the limit stop 4 is completely retracted into the movable groove 3. At this time, the pressure inside the movable groove 3 within the area covered by the patient increases, and the pressure inside the pressure chamber 21 increases through the second connecting groove 24, eventually causing the other limit stops 4 to move upward until they surround the patient.

[0036] The connecting mechanism 6 includes a valve seat 61 installed inside the mounting groove 25. The valve seat 61 is provided with a limiting groove 611 that extends vertically. A valve plate 62 is slidably connected inside the limiting groove 611. One end of the valve plate 62 corresponds to the piston plate 43. A second spring 63 is provided between the top of the valve plate 62 and the inner wall of the top of the mounting groove 25.

[0037] The valve seat 61 is provided with a transverse through groove 612, and the valve plate 62 is provided with a second through hole 621. The second through hole 621 corresponds to the through groove 612, and the two ends of the through groove 612 are respectively connected to the first connecting groove 23 and the movable groove 3.

[0038] The piston plate 43 is provided with a third connecting groove 422 inside. One end of the third connecting groove 422 is connected to the chamber 42, and the other end of the third connecting groove 422 extends to the outside of the piston plate 43. The third connecting groove 422 corresponds to the through groove 612 on the valve seat 61.

[0039] The lower sides of the limiting stop post 4 are provided with sliding grooves 421. A locking plate 423 is slidably connected in the sliding grooves 421. The end of the locking plate 423 located inside the chamber 42 is fixedly connected to the limiting plate 424. When the limiting stop post 4 located on the patient's periphery rises to its maximum range, its piston plate 43 drives the valve plate 62 to move upward, so that the second through hole 621 corresponds to the through groove 612. At this time, the pressure chamber 21 is connected to the chamber 42 through the first connecting groove 23, the through groove 612 and the third connecting groove 422. The chamber 42 is in a high pressure state, which causes the locking plate 423 to extend outward and be stuck on the top outer edge of the movable base 1, which can prevent the limiting stop post 4 on the patient's periphery from retracting. At the same time, the high pressure state inside the chamber 42 causes the expansion ball 5 to bulge.

[0040] Specifically, the limiting post 4 on the mattress body 2 is in a semi-extended state, that is, the length of the limiting post 4 extending out of the mattress body 2 is half of the total length of the limiting post 4. When the patient lies down, the limiting post 4 under the patient moves downward under the force of gravity. Under the action of the piston plate 43, the pressure inside the pressure chamber 21 increases, causing the limiting posts 4 around the patient to rise up and wrap around the patient. When the limiting post 4 rises to its maximum state, the piston plate 43 pushes the valve plate 62 upward, causing the second through hole 621 to correspond with the through groove 612. At this time, the third connecting groove 422 corresponds with the through groove 612, and the pressure chamber 21 finally connects with the chamber 42. Its high pressure state causes gas to pass through the longitudinal groove 412, the first through hole 52 and the connecting pipe 51, causing the expansion ball 5 to expand, providing better wrapping and cushioning for the patient.
