Description

Technical Field

[0001] This invention relates to the field of medical transport technology, and more particularly to transport equipment for life support devices for critically ill patients. Background Technology

[0002] Patient transfer devices, also known as patient transfer equipment or transfer assistive devices, are mobility aids that make it easier to safely transfer patients with limited mobility to wheelchairs, chairs, beds, cars, bathtubs, or toilets. Using these transfer devices can reduce the risk of patients falling and also alleviate the stress on caregivers.

[0003] Currently, most transport equipment used for critically ill patients consists of transport beds, along with life support equipment, including ventilators and electrocardiographs, to maintain the lives of critically ill patients during transport.

[0004] Because critically ill patients have lost their basic ability to maintain their posture and cannot withstand continuous shaking, and because transport beds for critically ill patients are mostly used during hospital transfers, long-distance transfers often require moving the transport bed by vehicle or airplane, making the entire transfer journey long and bumpy. Since patients have lost their basic ability to maintain their posture and cannot keep stable on the transport bed, they will experience continuous shaking. In such cases, most transport beds use elastic bands and restraints to restrain the patient. However, because some critically ill patients have wounds or open sores, the elastic bands and restraints cannot be tied too tightly. Furthermore, since the elastic bands and restraints are located at pressure points on the patient's body, they are prone to shifting with the shaking of the transport bed and the patient. Since critically ill patients require numerous life support devices to be connected to their bodies, shifting of the elastic bands and restraints on the patient's body can easily affect the connection between the life support devices and the patient. Summary of the Invention

[0005] The purpose of this invention is to provide a transport device for life support equipment for critically ill patients, so as to stabilize the position of locking structures such as elastic restraint straps on the body surface of critically ill patients, and prevent excessive displacement of elastic restraint straps during long-distance transport due to the shaking of the transport bed and the patient, thereby affecting the connection between life support equipment and critically ill patients.

[0006] To achieve the above objectives, the present invention provides a transport device for life support equipment for critically ill patients, including a transport bed body. The transport bed body includes a support bed, a life support component, and a restraint component. The life support component is disposed on one side of the bed board portion of the support bed, and the restraint component is disposed on the edge of the bed board portion of the support bed. A pulling and positioning mechanism, the pulling and positioning mechanism comprising a side pulling component and a middle pulling component; The side-pulling components are arranged in pairs, mirror-symmetrically on both sides of the bed board support. Each side-pulling component includes a telescopic rotating frame, a concealing and storage component, and a pulling and positioning component. The telescopic rotating frame is located on one side of the bed board support, the concealing and storage component is located at the end of the telescopic rotating frame, and the pulling and positioning component is located below the horizontal frame of the telescopic rotating frame. The intermediate tensioning assembly is disposed in the middle part of the bed board support section, and is located between the two side tensioning assemblies. The intermediate tensioning assembly has a similar structure to the side tensioning assemblies. The pulling and positioning component includes a steering component, a pulling rope, an elastic connector, and a strap hook. Multiple steering components are arranged in a group and are parallel to each other below the transverse frame of the telescopic rotating frame. One end of the pulling rope is connected to the steering component, the elastic connector is located at the other end of the pulling rope, and the strap hook is located on the elastic connector. Both the side tensioning assembly and the middle tensioning assembly are slidably installed along the edge of the bed board portion of the support bed. The tensioning positioning component of the side tensioning assembly and the tensioning positioning component of the middle tensioning assembly cooperate with each other to form a positioning structure of opposing tensioning constraint components above the bed board portion of the support bed.

[0007] As a further improvement to this technical solution, the intermediate tensioning component includes an extension base frame and a tensioning positioning component. The extension base frame is located on one side of the middle of the support bed board, and the tensioning positioning component is located below the transverse frame of the extension base frame. The tensioning positioning component of the intermediate tensioning component has the same structure as the tensioning positioning component of the side tensioning component. The extension base frame includes a mounting frame and a stacked extension frame. The mounting frame is rotatably mounted on one side of the middle of the support bed board. The stacked extension frame is horizontally positioned at the end of the mounting frame. The steering component of the intermediate tensioning assembly is located below the frame of the stacked extension frame.

[0008] As a further improvement to this technical solution, the stacked extension frame includes multiple telescopic frame sections, and tension positioning components are provided on all multiple telescopic frame sections.

[0009] As a further improvement to this technical solution, the telescopic rotating frame includes a telescopic upright and a mounting top frame. The telescopic upright is rotatably mounted on one side of the bed board portion of the supporting bed, and the telescopic upright is tightly connected to the bed board portion of the supporting bed. The mounting top frame is located at the top of the telescopic upright. The concealing and storage assembly includes a concealing plate and a storage shaft. The concealing plate is located inside the mounting top frame and conceals one side of the pull positioning member. The storage shaft is horizontally arranged inside the mounting top frame and is located below the pull positioning member.

[0010] As a further improvement to this technical solution, a winding shaft for winding the pulling rope is provided on the inner side of the steering component, so that the length of the pulling rope under the steering component can be controlled by rotating the winding shaft. The pulling rope is a spring rope that can elastically deform within a certain range, and the pulling rope maintains a tendency to move away from the bed board support.

[0011] As a further improvement to this technical solution, the threading hook includes a bent hose and a bent hook, wherein the bent hose is disposed at the end of the elastic connector and the bent hook is disposed at the end of the bent hose; The flexible hose is a carbon steel hose that can be easily bent.

[0012] As a further improvement to this technical solution, the constraint assembly includes a constraint strap and a winding member. The winding members are arranged in pairs and are respectively set at the two edges of the bed board portion of the support bed. One end of the constraint strap is connected to the winding member, and the other end passes over the top of the bed board portion of the support bed and is connected to the winding member on the other side. The strap hook acts on the constraint strap.

[0013] As a further improvement to this technical solution, an anti-bending rubber strip is provided in the middle of the constraint strap body along the length of the constraint strap.

[0014] Compared with the prior art, the present invention provides a transport device for life support equipment for critically ill patients, which has the following beneficial effects: This invention pierces the two edges of the restraint strap with a bent hook, and then the elastic pull of the two sides of the restraint strap is achieved by the elastic pull of the pull ropes and elastic connectors, so that the two edges of the restraint strap are pulled upwards. At the same time, it forms a counter-pulling positioning of the restraint strap, preventing the restraint strap from shifting with the swaying of the patient during the transfer. This prevents the restraint strap from affecting the connection structure between the life support components and the patient's body surface during the transfer, and ensures the connection between the life support components and the patient.

[0015] In addition, the positions of the side traction components and the middle traction components on the bed can be adjusted according to the position of the restraint straps. At the same time, the multiple traction positioning parts of the side traction components and the multiple traction positioning parts of the middle traction components can form a variety of traction methods and traction positions for the restraint straps wrapped around the patient's body surface.

Detailed Implementation

[0018] 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.

[0019] Reference Figure 1-8 The transport equipment for life support devices for critically ill patients is designed to prevent excessive displacement of restraint straps on the patient's body surface during transport, thereby avoiding contact and interference between the restraint straps and the connection between various life support devices and the critically ill patient. The equipment includes a transport bed body and a pulling and positioning mechanism. The transport bed body includes a support bed 1, a life support component 2, and a restraint component 3. The life support component 2 is located on one side of the bed board of the support bed 1 and includes various life support devices, such as ventilators and electrocardiogram equipment. The restraint component 3 is located at the edge of the bed board of the support bed 1. The pulling and positioning mechanism includes a side pulling component 4 and a middle pulling component 5; The two side-pulling components 4 are arranged in a group and mirror-symmetrically on both sides of the bed board of the support bed 1. The side-pulling component 4 includes a telescopic rotating frame 41, a cover and storage component 42 and a pulling positioning component. The telescopic rotating frame 41 is located on one side of the bed board of the support bed 1, the cover and storage component 42 is located at the end of the telescopic rotating frame 41, and the pulling positioning component is located below the horizontal frame of the telescopic rotating frame 41. The intermediate tensioning component 5 is located in the middle part of the bed board of the support bed 1, and the intermediate tensioning component 5 is located between the two side tensioning components 4. The intermediate tensioning component 5 has a similar structure to the side tensioning components 4. The pulling and positioning component includes a steering component 6, a pulling rope 7, an elastic connector 8, and a belt hook 9. Multiple steering components 6 are arranged in a group and are parallel to each other below the transverse frame of the telescopic rotating frame 41. One end of the pulling rope 7 is connected to the steering component 6, the elastic connector 8 is located at the other end of the pulling rope 7, and the belt hook 9 is located on the elastic connector 8. Both the side tensioning assembly 4 and the middle tensioning assembly 5 are slidably installed along the edge of the bed board portion of the supporting bed 1, such as... Figure 1 and Figure 3 As shown, a guide groove is provided on the edge of the bed board portion of the support bed 1. The bottom ends of the side pulling assembly 4 and the middle pulling assembly 5 pass through the guide groove and fit tightly against the inner wall of the guide groove, so that the side pulling assembly 4 and the middle pulling assembly 5 can move horizontally along the guide groove and stop after moving. This allows the position of the side pulling assembly 4 and the middle pulling assembly 5 on the bed board portion of the support bed 1 to be controlled. The pulling positioning parts of the side pulling assembly 4 and the pulling positioning parts of the middle pulling assembly 5 cooperate with each other to form a positioning structure of the opposing pulling constraint assembly 3 above the bed board portion of the support bed 1.

[0020] When the restraint assembly 3, used to restrain the strap, is wrapped around the patient's body surface, the strap hooks 9 of the side pull assembly 4 and the middle pull assembly 5 can hook onto both sides of the strap respectively. The pull rope 7 and the elastic connector 8 provide upward pulling and elastic buffering to the strap, forming a counter-directional tilting and positioning effect. The edge of the strap of the restraint assembly 3 is pulled upward and bent. At this time, when the transport bed and the patient shake during the transfer process, the position of the strap on the patient's body surface can be restricted without affecting the normal use of the strap, preventing the strap from shifting excessively, thereby preventing the strap from contacting other life support equipment and the structure connected to the patient. At the same time, the upward bending of the strap edge of the restraint assembly 3 can also reduce the impact on the connection position and connection structure when the strap shifts slightly on the patient's body surface.

[0021] The intermediate traction component 5 includes an extension base frame 51 and a traction positioning component. The extension base frame 51 is located on one side of the middle of the bed board of the support bed 1, and the traction positioning component is located below the transverse frame of the extension base frame 51. The traction positioning component of the intermediate traction component 5 has the same structure as the traction positioning component of the side traction component 4. The extension base frame 51 includes an installation frame 511 and a stacked extension frame 512. The installation frame 511 is rotatably installed on one side of the middle of the bed board of the support bed 1. The stacked extension frame 512 is horizontally arranged at the end of the installation frame 511. The steering component 6 of the intermediate pulling assembly 5 is arranged below the frame of the stacked extension frame 512.

[0022] like Figure 4 As shown, the stacked extension frame 512 includes multiple telescopic frame sections, and the pulling and positioning components are provided on each of the multiple telescopic frame sections, so that the stacked extension frame 512, located above the bed board of the support bed 1, can carry multiple pulling and positioning components, and can extend, retract, and fold when needed, preventing the middle pulling component 5 from affecting the patient's movement when getting into bed.

[0023] The telescopic rotating frame 41 includes a telescopic upright frame 411 and a mounting top frame 412. The telescopic upright frame 411 is rotatably mounted on one side of the bed board portion of the supporting bed 1, and the telescopic upright frame 411 is tightly connected to the bed board portion of the supporting bed 1, so that the telescopic upright frame 411 can maintain an upright state under the frictional force at the connection point after rotation. The mounting top frame 412 is located at the top of the telescopic upright frame 411. The concealing and storage component 42 includes a concealing plate 421 and a storage shaft 422. The concealing plate 421 is located inside the mounting top frame 412 and conceals one side of the pull positioning member. The storage shaft 422 is horizontally arranged inside the mounting top frame 412 and is located below the pull positioning member. The strap hook 9 of the pull positioning member can hook the storage shaft 422, thereby realizing storage.

[0024] In addition, such as Figure 3 As shown, the connection between the telescopic upright frame 411 and the edge of the bed board of the support bed 1 can rotate, so that when needed, the telescopic upright frame 411 can be rotated and the horizontal part of the mounting top frame 412 can be attached to the end of the bed board of the support bed 1, thereby realizing the horizontal storage of the telescopic rotating frame 41. When the patient is transferred to the support bed 1, the telescopic rotating frame 41 can be retracted to prevent obstruction of the patient.

[0025] like Figure 6 As shown, a winding shaft for winding the pull rope 7 is provided on the inner side of the steering component 6, so that the length of the pull rope 7 under the steering component 6 can be controlled by rotating the winding shaft. The pull rope 7 is a spring rope that can elastically deform within a certain range, and the pull rope 7 maintains a tendency to move away from the bed board part of the supporting bed 1.

[0026] like Figure 5As shown, the threading hook 9 includes a bent hose 91 and a bent hook 92. The bent hose 91 is disposed at the end of the elastic connector 8, and the bent hook 92 is disposed at the end of the bent hose 91. Among them, the bending hose 91 is a carbon steel hose that can be easily bent, so that the bending hose 91 can be bent as needed at the end of the pulling rope 7.

[0027] like Figure 7 As shown, the constraint assembly 3 includes a constraint band 31 and a winding member 32. The winding members 32 are arranged in pairs and are respectively set at the two sides of the bed board portion of the support bed 1. One end of the constraint band 31 is connected to the winding member 32, and the other end passes over the top of the bed board portion of the support bed 1 and is connected to the winding member 32 on the other side. The belt hook 9 acts on the constraint band 31.

[0028] like Figure 8 As shown, a bend-resistant rubber strip 10 is provided in the middle of the restraint strap 31 along the length of the restraint strap 31. Through the action of the bend-resistant rubber strip 10 in the middle part of the restraint strap 31, when the pulling rope 7 and the elastic connector 8 pull the restraint strap 31 upward at an angle, it can prevent the middle part of the restraint strap 31 from bending upward, prevent the restraint strap 31 from bending too much and reducing the contact area with the patient, and ensure the restraining force of the restraint strap 31.

[0029] It should be clarified that the tension positioning elements of the side tension assembly 4 and the middle tension assembly 5 do not necessarily need to act on the same restraint band 31 simultaneously. The tension positioning elements on the same telescopic rotating frame 41 can act on both sides of the restraint band 31 respectively, forming a tension at the edge of the restraint band 31 independently. At the same time, the tension positioning elements of the same stacked extension frame 512 can also act on both sides of the restraint band 31 respectively, forming independent tension. This allows the multiple tension positioning elements included in the side tension assembly 4 and the multiple tension positioning elements included in the middle tension assembly 5 to form variable tension on the restraint band 31 wrapped around the patient's body surface according to the adjustment of the positions of the side tension assembly 4 and the middle tension assembly 5 on the bed board of the support bed 1. This prevents the uncertainty of the wrapping position when the patient wraps the restraint band 31 from limiting the effect of the side tension assembly 4 and the middle tension assembly 5 on the restraint band 31.

[0030] Working principle: The critically ill patient lies down on the support bed 1, and various life support devices of the life support component 2 are connected to the patient's body surface. Multiple restraint straps 31 are then wrapped around the patient's body surface and locked in place by the wrapping element 32. Since the life support component 2 has many connection points on the patient's body surface, some restraint straps 31 are close to these points. Based on the position of the restraint straps 31 on the patient's body surface, the positions of the side pulling component 4 and the middle pulling component 5 on the bed board of the support bed 1 are adjusted. After adjustment, the rewinding shaft inside the steering component 6 is rotated as needed to control the length of the pulling rope 7. The bending degree of the bending hose 91 is then adjusted as needed. Finally, the bending hook 92 is pulled... Pulling the bending hose 91 and the pulling rope 7 causes the bending hook 92 to pierce one edge of the restraint strap 31. Then, through the elastic pulling of the pulling rope 7 and the elastic connector 8, the bending hook 92 pulls the restraint strap 31 upward at one edge. In the same way, other bending hooks 92 pierce the other edge of the restraint strap 31 and pull the restraint strap 31 upward at the other edge. Since the restraint strap 31 is pulled upward at both edges, and the pulling ropes 7 on both sides form opposing pulling and positioning of the restraint strap 31, it can prevent the restraint strap 31 from shifting and squeezing the connection structure between the life support component 2 and the patient's body surface when the patient moves on the support bed 1 during the transfer process, thus ensuring the connection between the life support component 2 and the patient.
