Description

Technical Field

[0001] This application relates to the technical field of patient transport equipment, and more particularly to a medical transport gantry. Background Technology

[0002] Medical transport frames are assistive devices commonly used in hospitals, emergency centers, and rehabilitation facilities, primarily to assist patients with limited mobility or inability to move independently in safe transfers. Currently, most transport frames on the market are seated designs, suitable for conscious patients who can maintain a sitting posture and do not have severe spinal or limb injuries. However, for patients who need to maintain a supine position to keep their airway open, require spinal immobilization, or have fractures or spinal cord injuries, seated frames are not only difficult to use but may also worsen their condition or cause secondary injury, limiting their application in critically ill, post-operative, and patients with special injuries.

[0003] Compared to traditional sitting-position slings, recumbent slings utilize a fully supportive sling structure to achieve supine patient transfer, effectively maintaining spinal stability during transport and preventing spinal misalignment or nerve compression caused by improper positioning. This type of sling is particularly suitable for patients who have not fully recovered from anesthesia, intensive care patients, and patients requiring strict positioning management, such as those with spinal injuries or pelvic fractures. Furthermore, recumbent slings provide a more even pressure distribution, reducing the risk of local pressure sores and facilitating standardized and safer patient transport procedures, demonstrating greater adaptability and safety in clinical nursing and emergency transport.

[0004] While reclining harnesses offer functional advantages over traditional seated harnesses, they still have significant shortcomings in practical use. First, most existing reclining harnesses lack adjustable lifting points, making it impossible to adjust the support points of the harness according to the patient's specific injury location. This makes it difficult to effectively avoid the affected area during lifting, easily causing pain or even worsening the injury, severely impacting the patient's transport experience. Second, even if some products attempt to incorporate adjustable lifting point structures, these components lack an automatic locking mechanism after adjustment, making them prone to shifting or loosening during lifting or transport, posing potential safety hazards. Utility Model Content

[0005] This application provides a medical transport sling that solves the technical problems of existing patient transport equipment lacking the function of adjusting the load-bearing support point by changing the lifting point, and the adjustable functional components lacking an automatic locking mechanism. The technical solution is as follows: This application provides a medical transport sling, including: a sling body having a plurality of arms for connecting a sling; a crossbeam disposed on the top of the sling body and extending along the length of the sling body; and an adjustment component disposed on the crossbeam, the adjustment component having a first state and a second state, the adjustment component being able to slide on the crossbeam when in the first state, and being fixed at the upper limit of the crossbeam when in the second state. The adjustment component changes weight when it is loaded by the hanger body, and then switches from the first state to the second state.

[0006] In one embodiment, the assembly further includes: a first rack mounted on the bottom of the crossbeam and extending along the length of the crossbeam; the adjusting assembly includes: a mounting base slidably fitted onto the crossbeam; and a second rack mounted in the mounting base; when the adjusting assembly is in a first state, the first rack and the second rack are separated; when the adjusting assembly is in a second state, the second rack engages with the first rack to limit and fix the mounting base on the crossbeam.

[0007] In one embodiment, the adjustment assembly further includes: a roller member rotatably mounted in the mounting base; when the adjustment assembly is in a first state, the roller member is rotatably supported on the top of the crossbeam to assist the mounting base in sliding on the crossbeam; when the adjustment assembly is in a second state, the roller member is separated from the crossbeam.

[0008] In one embodiment, the adjustment assembly further includes: an adjustment component installed in the mounting base, the adjustment component being elastically supported on the first rack to drive the first rack and the second rack to separate when the hanger body is unloaded; when the hanger body is loaded, the first rack compresses the adjustment component through the weight transmitted on the crossbeam until the second rack engages with the first rack.

[0009] In one embodiment, the adjusting component includes: a gear seat disposed in a mounting base; a first elastic element connected between the gear seat and the mounting base; and a gear member rotatably disposed in the gear seat, the gear member being supported by the elastic force of the first elastic element and meshing with a first rack.

[0010] In one embodiment, the adjusting component further includes: a rotating shaft rotatably disposed on a gear seat, a gear being synchronously rotatably mounted on the rotating shaft, an adjusting hole being provided on the mounting seat, one end of the rotating shaft passing through the adjusting hole and extending to the outside of the mounting seat; and a knob handle synchronously rotatably mounted on the rotating shaft and located on the outside of the mounting seat. The adjusting hole has a first end and a second end located below the first end. When the first rack separates from the second rack, the rotating shaft is displaced to the first end. When the second rack meshes with the first rack, the rotating shaft is displaced to the second end.

[0011] In one embodiment, the adjusting component further includes: a movable member slidably and telescopically disposed on the rotating shaft, and a limiting head abutting against the knob handle on the outer end of the movable member; the knob handle being sleeved on both the rotating shaft and the movable member; a second elastic element elastically supported between the movable member and the rotating shaft; when the knob handle is pulled to increase the distance between it and the mounting base, the knob handle drives the movable member and the rotating shaft to slide and stretch via the limiting head, so that the second elastic element stores elastic energy; a plurality of limiting holes are arranged circumferentially on the side of the knob handle near the mounting base, and a limiting pin that can be inserted into the limiting hole is provided on the side wall of the mounting base to restrict the rotation of the knob handle; when the knob handle is pulled to increase the distance between it and the mounting base, the limiting hole disengages from the limiting pin.

[0012] In one embodiment, a limiting pin is located above and / or below an adjustment hole, which has a strip-shaped structure to allow the knob handle to engage with a gear component and move with the first rack.

[0013] In one embodiment, it further includes an adapter, disposed on top of the adjustment assembly, for connecting a lifting rope.

[0014] In one embodiment, each boom is further provided with a limiting buckle for connecting the connecting strap on the sling; the limiting buckle includes: a hook, installed on each boom, the hook having an upper opening; and a spring arm, elastically flipped and disposed on the hook, the spring arm closing inside the hook and closing on the upper opening.

[0015] Compared with existing technologies, the medical transport sling proposed in the above technical solution, by setting a crossbeam extending along the length direction at the top of the sling body and configuring a sliding and automatically locking adjustment component on the crossbeam, allows the sling to flexibly adjust the force support point of the sling according to the specific injury location of the patient. Before lifting, the operator can freely slide the adjustment component according to the position of the patient's affected area, thereby changing the force distribution of the sling body and ensuring that the sling avoids painful or injured areas during the lifting process, significantly reducing patient discomfort and the risk of secondary injury. This function is particularly suitable for patients with spinal injuries, fractures, and those in the postoperative recovery period who have high requirements for body positioning, greatly improving the humanization of the transport process; this application expands the adaptability of the sling through the cooperative design of the crossbeam and adjustment component, enabling it to be personalized according to the needs of different patients, enhancing the versatility and flexibility of the equipment, and is especially suitable for multiple medical scenarios such as intensive care, emergency transport, and rehabilitation nursing. When in use, the adjustment mechanism can slide freely on the crossbeam when the gantry is not under load, facilitating quick positioning. Once the gantry bears the patient's weight, the adjustment mechanism is fixed to the crossbeam to prevent displacement of the lifting point due to vibration, movement, or accidental contact. This load-bearing-based state-switching mechanism requires no additional operation, effectively ensuring the safety and stability of the transport process.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0021] Reference Figure 1 As shown, an embodiment of this application proposes a medical transport gantry, which may include: a gantry body 1 having a plurality of arms 11 for connecting a gantry; a crossbeam 3 disposed on the top of the gantry body 1 and extending along the length of the gantry body 1; and an adjustment component 5 disposed on the crossbeam 3, the adjustment component 5 having a first state and a second state, the adjustment component 5 being able to slide on the crossbeam 3 when in the first state, and being fixed at the upper limit of the crossbeam 3 when in the second state; When the weight of the adjusting component 5 changes under the load of the hanger body 1, it switches from the first state to the second state.

[0022] Specifically, in the technical solution adopted in this application, the hanger body 1 has several booms 11 for connecting the hanging bag. Each boom 11 is arranged circumferentially along the hanger body 1, so that when the boom 11 is connected to the hanging bag, the hanging bag can be used for the user to lie down. A crossbeam 3 is provided at the top of the hanger body 1. The crossbeam 3 extends along the length of the hanger body 1, and an adjustment component 5 is slidably disposed on the crossbeam 3. Thus, the lifting point of the hanger body 1 can be adjusted by the cooperation of the crossbeam 3 and the adjustment component 5, so as to adjust the support point of the user lying in the hanging bag. Before the hanger body 1 is raised, since the hanger body 1 does not carry the user, the adjustment component 5 is in the first state. The adjustment component 5 can slide on the crossbeam 3 to adjust the position of the adjustment component 5 on the crossbeam 3. When in use, the hanger body 1 is raised by adjusting component 5. Since the hanger body 1 carries the user, the adjusting component 5 is switched from the first state to the second state so that the adjusting component 5 is fixed on the crossbeam 3. This can fix the adjusting component 5 on the crossbeam 3 during transportation and prevent the support point on the hanger used to support the user from changing again.

[0023] Furthermore, refer to Figure 2 and Figure 3As shown, in some embodiments, it further includes: a first rack 4, installed at the bottom of the crossbeam 3 and extending along the length of the crossbeam 3; the adjusting component 5 includes: a mounting base 51, slidably sleeved on the crossbeam 3; and a second rack 52, installed in the mounting base 51; when the adjusting component 5 is in a first state, the first rack 4 and the second rack 52 are separated; when the adjusting component 5 is in a second state, the second rack 52 engages with the first rack 4 so as to limit and fix the mounting base 51 on the crossbeam 3.

[0024] Specifically, in the technical solution adopted in this application, in order to realize that the adjustment component 5 has a first state and a second state, in some embodiments, a first rack 4 can be installed at the bottom of the crossbeam 3. When the first rack 4 cooperates with the adjustment component 5, it can limit and fix the adjustment component 5 on the crossbeam 3. In this embodiment, the adjustment component 5 may include: a mounting seat 51 disposed on the crossbeam 3 in a sleeve manner and a second rack 52 installed in the mounting seat 51. When the hanger body 1 is not carrying a user through the basket, the first rack 4 and the second rack 52 are separated, and the mounting seat 51 can slide on the crossbeam 3; when in use, when the hanger body 1 carries a user through the basket, the first rack 4 and the second rack 52 are engaged with each other due to gravity, so as to limit the sliding of the mounting seat 51 on the crossbeam 3.

[0025] Furthermore, refer to Figure 3 and Figure 4 As shown, in some embodiments, the adjustment assembly 5 further includes a roller 53 rotatably mounted in the mounting base 51; when the adjustment assembly 5 is in a first state, the roller 53 is rotatably supported on the top of the crossbeam 3 to assist the mounting base 51 in sliding on the crossbeam 3; when the adjustment assembly 5 is in a second state, the roller 53 is separated from the crossbeam 3.

[0026] Specifically, in the technical solution adopted in this application, in order to reduce the friction generated when the mounting base 51 slides on the crossbeam 3, a roller component 53 is also provided in the mounting base 51. The roller component 53 is rotatably installed in the mounting base 51. When the first rack 4 and the second rack 52 are separated, the top surface of the crossbeam 3 is in contact with the roller component 53. When the mounting base 51 slides on the crossbeam 3, the roller component 53 rotates based on the friction generated by the top surface of the crossbeam 3, so as to convert the translational friction between the mounting base 51 and the crossbeam 3 into rolling friction, effectively reducing the frictional loss between the mounting base 51 and the crossbeam 3 and extending the service life.

[0027] Furthermore, refer to Figure 3 and Figure 4As shown, in some embodiments, the adjustment assembly 5 further includes an adjustment component installed in the mounting base 51. The adjustment component is elastically supported on the first rack 4 to drive the first rack 4 to separate from the second rack 52 when the hanger body 1 is unloaded. When the hanger body 1 is loaded, the first rack 4 compresses the adjustment component through the weight transmitted on the crossbeam 3 until the second rack 52 engages with the first rack 4.

[0028] Specifically, in the technical solution adopted in this application, in order to achieve the separation of the first rack 4 and the second rack 52 when the hanger body 1 is not carrying a user through the hanging basket, in some embodiments, the mounting base 51 is also provided with an adjusting component. This adjusting component is elastically supported on the first rack 4 to drive the first rack 4 on the crossbeam 3 to separate from the second rack 52. The elastic force on the adjusting component is greater than the weight of the entire adjusting assembly 5. In use, because the weight of the user exceeds the elastic force of the adjusting component, the elastic support of the adjusting component is temporarily lost, so that the first rack 4 and the second rack 52 engage, so that when carrying the user, the mounting base 51 can be limited and fixed on the crossbeam 3 by the engagement of the first rack 4 and the second rack 52.

[0029] Furthermore, refer to Figure 3 and Figure 4 As shown, in some embodiments, the adjusting component includes: a gear seat 54 disposed in a mounting base 51; a first elastic element 56 connected between the gear seat 54 and the mounting base 51; and a gear 55 rotatably disposed in the gear seat 54, and the gear 55 meshes with the first rack 4 via the elastic support of the first elastic element 56.

[0030] Specifically, in the technical solution adopted in this application, in order to enable the mounting base 51 to be precisely adjusted on the crossbeam 3 by means of an adjusting component, the adjusting component includes at least: a gear seat 54, a gear component 55 disposed on the gear seat 54, and a first elastic element 56 located at the bottom of the gear seat 54; the first elastic element 56 is elastically supported between the gear seat 54 and the mounting base 51 to drive the gear component 55 on the gear seat 54 to mesh with the first rack 4, and under the elastic force of the first elastic element 56, the gear component 55 can move synchronously with the first rack 4. It can be understood that regardless of whether the adjusting component 51 is in the first state or the second state, the gear component 55 is always meshed with the first rack 4. In use, when the mounting base 51 slides on the crossbeam 3, the gear component 55 rotates based on the first rack 4, so that the mounting base 51 can form a damping force according to the meshing of the gear component 55 and the first rack 4, thereby improving the accuracy of sliding and adjusting the mounting base 51 on the crossbeam 3. When in use, this prevents the mounting base 51 from undergoing large-scale displacement on the crossbeam 3, thus avoiding unnecessary risks to the user, when the crossbeam 3 has a certain tilt angle or when the hanger body 1 is lifted. Furthermore, refer to Figure 2, Figure 4 and Figure 6 As shown, in some embodiments, the adjusting component further includes: a rotating shaft 57 rotatably disposed on the gear seat 54, a gear 55 synchronously rotatably mounted on the rotating shaft 57, an adjusting hole 510 provided on the mounting base 51, one end of the rotating shaft 57 passing through the adjusting hole 510 and extending to the outside of the mounting base 51; and a knob handle synchronously rotatably mounted on the rotating shaft 57, located on the outside of the mounting base 51. The adjusting hole 510 has a first end and a second end located below the first end. When the first rack 4 is separated from the second rack 52, the rotating shaft 57 is displaced to the first end. When the second rack 52 is engaged with the first rack 4, the rotating shaft 57 is displaced to the second end.

[0031] Specifically, in the technical solution adopted in this application, in order to further improve the accuracy of the sliding adjustment of the mounting base 51, a rotating handle 59 is provided on the outside of the mounting base 51. By rotating the rotating handle 59, the gear component 55 is driven to rotate in the mounting base 51, so as to achieve the purpose of adjusting the mounting base 51 on the crossbeam 3. Specifically, the gear component 55 is mounted on the gear seat 54 via the rotating shaft component 57, and the gear component 55 can rotate synchronously with the rotating shaft component 57. An adjustment hole 510 is provided on the mounting base 51, and one end of the rotating shaft component 57 passes through the adjustment hole 510 and out of the mounting base 51. The rotating handle 59 is synchronously rotated and sleeved on the rotating shaft component 57, and is located on the outside of the mounting base 51. In use, the rotating handle 59 is manually rotated so that the rotating handle 59 drives the gear component 55 to rotate in the gear seat 54 via the rotating shaft component 57. Since the gear component 55 is always meshed on the first rack 4, the first rack 4 and the second rack 52 are in a separated state. The gear component 55 and the first rack 4 cooperate to drive the mounting base 51 to slide on the crossbeam 3.

[0032] In one embodiment, the adjustment hole 510 may be a strip-shaped structure extending in the height direction of the mounting base 51, having a first end and a second end located above the first end, thereby allowing the gear seat 54, gear component 55, rotating shaft component 57, and rotating handle 59 to move via the first elastic element 56 in conjunction with the first rack 4. When the hanger body 1 is unloaded, the first elastic element 56 elastically supports the gear seat 54 to move toward the first rack 4, thereby driving the first rack 4 to separate from the second rack 52, and causing the gear component 55 to move with the first rack 4, while the rotating shaft component 57 is located at the first end of the adjustment hole 510; when the hanger body 1 is loaded, the first rack 4 moves toward the gear seat 54 and compresses the first elastic element 56 until the second rack 52 meshes with the first rack 4, and the rotating shaft component 57 is displaced from the first end to the second end of the adjustment hole 510.

[0033] Furthermore, refer to Figure 4 and Figure 5As shown, in some embodiments, the adjusting component further includes: a movable member 58, which is slidably and telescopically disposed on the rotating shaft 57, and a limiting head abutting against the knob handle is provided on the outer end of the movable member 58; the knob handle is sleeved on the rotating shaft 57 and the movable member 58; a second elastic element, which is elastically supported between the movable member 58 and the rotating shaft 57; when the knob handle is pulled to increase the distance between it and the mounting base 51, the knob handle drives the movable member 58 and the rotating shaft 57 to slide and stretch through the limiting head, so that the second elastic element stores elastic energy; a plurality of limiting holes 591 are arranged circumferentially on the side of the knob handle near the mounting base 51, and a limiting pin 511 that can be inserted into the limiting hole 591 is provided on the side wall of the mounting base 51 to restrict the rotation of the knob handle; when the knob handle is pulled to increase the distance between it and the mounting base 51, the limiting hole 591 disengages from the limiting pin 511.

[0034] Specifically, in the technical solution adopted in this application, in order to restrict the rotary handle 59 from rotating freely, in one embodiment, the adjusting component may further include: a movable member 58 and a second elastic element. The movable member 58 may be a telescopic sleeve, and the movable member 58 is connected to the rotating shaft 57 by a sliding sleeve, so that the movable member 58 can have a telescopic function based on the rotating shaft 57; while the second elastic element is elastically supported between the movable member 58 and the rotating shaft 57, and may be a compression spring or a tension spring. When the second elastic element is a compression spring, it can be sleeved on the movable member 58. When the movable member 58 is pulled and slidably stretched based on the rotating shaft 57, the movable member 58 can have a telescopic function. The ends of the movable member 58 and the pivot member 57 can compress the second elastic element, so that the second elastic element stores elastic energy. After the movable member 58 is released, the movable member 58 returns to its initial position based on the elastic energy stored in the second elastic element. When the second elastic element is a tension spring, the second elastic element can be arranged inside the pivot member 57, and the second elastic element connects the movable member 58 and the pivot member 57. When the movable member 58 is pulled and slidably stretched based on the pivot member 57, the movable member 58 stretches the second elastic element, so that the second elastic element stores elastic energy. After the movable member 58 is released, the movable member 58 returns to its initial position based on the elastic energy stored in the second elastic element. In this embodiment, the rotating handle 59 can be sleeved on both the rotating shaft 57 and the movable part 58, and a limiting head is provided at the end of the movable part 58. When the rotating handle 59 is pulled to increase the distance between it and the mounting base 51, the rotating handle 59 can drive the movable part 58 to slide and stretch based on the rotating shaft 57 through the limiting head. In this embodiment, the gear part 55 can only be driven to rotate by the rotating handle 59 after the distance between it and the mounting base 51 is increased by pulling the rotating handle 59. Specifically, a limiting pin 511 is provided on the side wall of the mounting base 51, and a limiting hole 591 is opened circumferentially on the side of the rotating handle 59 near the mounting base 51. When the movable part 58 is contracted into the rotating shaft 57 by the elastic force of the second elastic element, the limiting pin 511 passes into the corresponding limiting hole 591 to restrict the rotation of the rotating handle 59 on the mounting base 51. When it is necessary to rotate the rotary handle 59, the rotary handle 59 can be manually pulled to increase the distance between the rotary handle 59 and the mounting base 51, so that the limit pin 511 separates from the corresponding limit hole 591, thereby allowing the rotary handle 59 to rotate synchronously and drive the gear component 55 to rotate. At the same time, the rotary handle 59 can pull the movable component 58 in the rotating shaft component 57 through the limit head to slide and stretch, so that the second elastic element can store elastic energy. When the rotary handle 59 is released, the second elastic element rebounds and drives the movable component 58 to retract into the rotating shaft component 57, thereby driving the rotary handle 59 back to its original position. The limit pin 511 is then inserted into the corresponding limit hole 591 to restrict the rotation of the rotary handle 59.

[0035] Furthermore, refer to Figure 5 As shown, in some embodiments, the limiting pin 511 is located above and / or below the adjusting hole 510, and the limiting hole 591 has a strip-shaped structure so that the knob handle can cooperate with the gear 55 to move with the first rack 4.

[0036] Specifically, in the technical solution adopted in this application, in order to restrict the rotation of the rotary handle 59 while allowing the adjusting component to follow the displacement of the first rack 4, the limiting pin 511 can be set directly above or below the adjusting hole 510, or the number of limiting pins 511 can be increased to two, located directly above and below the adjusting hole 510 respectively; while the limiting hole 591 is set as a strip structure, when one limiting hole 591 corresponds to the limiting pin 511, the extending direction of the limiting hole 591 is parallel to the height of the mounting base 51. The direction of the limit hole 591 of the strip structure is consistent with the direction of the center of the rotary handle 59 towards its outer edge. Since the limit pin 511 is located directly above and / or directly below the adjustment hole 510, when the limit hole 591 and the limit pin 511 correspond, the extension direction of the limit hole 591 is the same as the displacement direction of the gear 55 with the first rack 4, which is the height direction of the mounting base 51. In this embodiment, the rotary handle 59 can move together with the gear 55 to follow the first rack 4.

[0037] Furthermore, refer to Figure 2 and Figure 7 As shown, in some embodiments, it also includes: an adapter 6, disposed on top of the adjustment assembly 5, for connecting the lifting rope.

[0038] Specifically, in the technical solution adopted in this application, the adapter component 6 may include: a first connector 61 and a second connector 62. The first connector 61 can be connected to the hoisting rope, while the second connector 62 is detachably embedded in the first connector 61 and can be connected to the mounting seat 51 in the adjustment assembly 5. Thus, the cooperation between the first connector 61 and the second connector in the adapter component 6 enables the mounting seat 51 to be connected to the hoisting rope, so that the adjustment assembly 5 can form a hoisting point on the crossbeam 3.

[0039] Furthermore, refer to Figure 1 and Figure 8 As shown, in some embodiments, each boom 11 is also provided with a limiting buckle 2, which is used to connect the connecting strap on the sling; the limiting buckle 2 includes: a hook 21, which is installed on each boom 11 and has an upper opening; and an elastic arm 22, which is elastically flipped and disposed on the hook 21 and is closed on the upper opening inside the hook 21.

[0040] Specifically, in the technical solution adopted in this application, since the medical transport sling proposed in this application is a reclining type, the sling body 1 can be designed as a closed-loop structure, preferably rectangular, and each arm 11 is arranged circumferentially on the sling body 1. In order to achieve a more stable connection between the arm 11 and the hanging ring on the sling, each arm 11 is also provided with a limiting buckle 2. The limiting buckle 2 may include: a hook 21 and an elastic arm 22. The hook 21 has an upper opening so that the hanging ring on the sling can pass through. The hook 21 is inserted through the upper opening; the elastic arm 22 is elastically flipped on the hook 21. In normal condition, the elastic arm 22 can close the upper opening of the hook 21. By flipping the elastic arm 22 inward into the hook 21, the upper opening of the hook 21 can be opened to allow the hanging ring on the bag to be moved in or out. The elastic arm 22 can be installed on the hook 21 by a torsion spring so that the elastic arm 22 can automatically reset by the elastic force of the torsion spring to close the upper opening of the hook 21.
