Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically, to an emergency patient transport bed that can be quickly inflated and deflated. Background Technology

[0002] Currently, medical inflatable mattresses are widely used in hospitals. Chinese patent application CN112245166A discloses a medical inflatable mattress, including a base pad with inflatable pads on both the front and back sides. The inflatable pads include an upper body air pad and a lower body air pad. The upper body air pad is connected to the base pad by hooks and loops, and the lower body air pad is connected to the base pad by hooks and loops. The upper body air pad and the lower body air pad are respectively provided with a number of first air bladders and a number of second air bladders. In emergency situations, stretcher beds are often needed (such as the stretcher bed disclosed in document CN115721484A). The combination of an airbag bed and a stretcher bed forms an emergency bed. During an emergency, medical staff need to enter the residential building, place the patient on the airbag bed, and then use the airbag bed to transfer the patient to the emergency vehicle. The patient and the airbag bed need to be placed on the stretcher bed (with several wheels at the bottom) so that after the ambulance arrives at the hospital, the stretcher bed can be transferred to the hospital's emergency area along with the airbag bed and the patient.

[0003] However, the existing solutions have the following problems: when using airbag beds to transport patients in the stairwells / elevators of residential buildings, the stairwells / elevators are relatively narrow and the airbag beds are large, making it very inconvenient to transport patients in the limited space. Moreover, the airbag beds may tilt during the transport process, which may cause the patient's body to move or even fall off the bed, posing a danger. Furthermore, the existing airbag beds are not suitable for patients who cannot lie down normally. Utility Model Content

[0004] The purpose of this invention is to provide an emergency patient transport bed that can be quickly inflated and deflated to solve the problems existing in the prior art.

[0005] The purpose of this utility model is achieved as follows: an emergency patient transport bed that can be quickly inflated and deflated, comprising:

[0006] An airbag bed used for transporting patients, which can be combined with a stretcher bed, consists of a mattress and several airbags located on the upper side of the mattress.

[0007] A transfer frame that can be folded up and down and placed on a stretcher bed, wherein the mattress part is configured as a deformable structure, the transfer frame supports and connects to the airbag bed body, the transfer frame is divided into an upper body support for supporting the upper body of the patient and a lower body support for supporting the lower body of the patient, and the upper body support is rotatably and adjustablely connected to the lower body support.

[0008] Furthermore, both the upper body support and the lower body support are connected to at least two straps, which are used to secure the patient to the airbag bed during transport.

[0009] Furthermore, handles are fixed to the head side and the left and right sides of the upper body support, and handles are fixed to the left and right sides of the lower body support.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. Some patients cannot lie down due to special reasons, or the space in the stairs / elevator is relatively small. The transfer frame can be folded and the folding angle can be adjusted to adapt to the relatively small space in the stairs / elevator. Since the airbag bed can be deformed, the airbag bed will also deform accordingly when the folding angle of the transfer frame is adjusted, so that the patient can maintain a sitting position during the transfer, better stabilize the patient's position on the airbag bed, and facilitate the movement of medical staff.

[0012] 2. During transport, straps are used to secure the patient to the airbag bed, thereby better fixing the patient's position and preventing the patient from shifting during transport. Attached Figure Description

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 , 6 As shown, a rapidly inflatable and deflated emergency patient transport bed is proposed, comprising:

[0022] The stretcher bed 3 has several rollers 305 installed at its bottom, and its support surface is covered with a silicone pad 301 and is fixedly connected with a front limit stop 302, a rear limit stop 303 and two side limit stops 304.

[0023] An airbag bed 1 for transporting patients, which can be combined with a stretcher bed 3, consists of a mattress part 1b and several airbags 1a located on the upper side of the mattress part 1b.

[0024] The transfer frame 2 is foldable and can be placed on the stretcher bed 3. The mattress part 1b is a deformable structure. The transfer frame 2 supports and connects to the airbag bed 1. The transfer frame 2 is divided into an upper body support 201 that supports the upper body of the patient and a lower body support 202 that supports the lower body of the patient. The upper body support 201 is rotatably and adjustablely connected to the lower body support 202.

[0025] Among them, such as Figure 4 , 5 As shown, the airbag bed 1 and its transport frame 2 are used independently when transporting patients in stairwells. Some patients cannot lie down due to special reasons, or the space in the stairwell / elevator is relatively small. The transport frame 2 can be folded and the folding angle can be adjusted to adapt to the relatively small stairwell / elevator space. Since the airbag bed 1 is deformable, the airbag bed 1 will also deform accordingly when the folding angle of the transport frame 2 is adjusted, so that the patient can maintain a sitting position during the transport, better stabilize the patient's position on the airbag bed 1, and facilitate the movement of medical staff. It can also accommodate patients who cannot lie down due to special reasons. When transporting patients to the ambulance or pushing them into the emergency room, the airbag bed 1 and its transport frame 2 can be placed on the stretcher bed 3. Medical staff can quickly push the stretcher bed 3 into the emergency room so that the patient can be smoothly transported to the treatment location.

[0026] As one of the preferred solutions, both the upper body support 201 and the lower body support 202 have an outer frame and a supporting wire mesh 204 fixed within the outer frame. Like the bed frame of a wire bed, both the upper body support 201 and the lower body support 202 are C-shaped frames. The C-shaped frames of the upper body support 201 and the lower body support 202 are arranged opposite to each other to form a space to accommodate the airbag bed 1. The airbag bed 1 is confined within the space constructed by the C-shaped frames of the upper body support 201 and the lower body support 202. The supporting wire mesh 204 supports and connects the airbag bed 1, just like the mattress of a wire bed.

[0027] To better secure the patient's body, both the upper body support 201 and the lower body support 202 are connected to two straps 205. The straps 205 are of a conventional type and can be untied and tied. During transport, the straps 205 are used to secure the patient to the airbag bed 1, thereby better securing the patient's position and preventing the patient from shifting during transport.

[0028] To facilitate the movement of the airbag bed 1 and its transport frame 2 by medical staff, handles 203 are fixed on the head side and the left and right sides of the upper body support 201, and handles 203 are fixed on the left and right sides of the lower body support 202, so that it can be operated by four people during the movement.

[0029] When the airbag bed 1 and its transfer frame 2 are transferred to the stretcher bed 3, the transfer frame 2 is placed on the silicone pad 301 and is within the area defined by all the limit bars. The silicone pad 301 is used to prevent the airbag bed 1 and its transfer frame 2 from sliding. The front limit bar 302, the rear limit bar 303 and the side limit bars 304 are used to limit the front, back and left and right positions of the airbag bed 1 respectively.

[0030] The aforementioned transfer frame 2 is equipped with a pair of hinge assemblies distributed on the left and right sides. The upper body support 201 is connected to the lower body support 202 in an adjustable manner by rotating up and down through the two hinge assemblies.

[0031] The hinge assembly mentioned above includes:

[0032] Adjusting the central axis 208, the upper body support 201 is connected to the lower body support 202 by rotating up and down through the central axis 208;

[0033] The guide hole 207 and the upper body support 201 are connected by a sliding pin 206. The sliding pin 206 is parallel to the adjustment pivot 208. The sliding pin 206 is movably inserted into the guide hole 207. The guide hole 207 is an arc-shaped hole, and the center of the guide hole 207 is on the central axis of the adjustment pivot 208.

[0034] In order to limit the angle range between the upper support 201 and the lower support 202, the guide hole 207 is in the shape of a 90° arc. When the angle between the upper support 201 and the lower support 202 is a right angle, the sliding pin 206 abuts against one end of the guide hole 207. When the entire transfer frame 2 is flattened, the sliding pin 206 abuts against the other end of the guide hole 207. Therefore, the upper support 201 can be erected relative to the lower support 202 or laid completely flat, thereby using the guide hole 207 to limit the range of rotation adjustment angle of the upper support 201.

[0035] like Figure 2 , 5 As shown, since the sliding pin 206 is in active engagement with the guide hole 207, the adjusting pivot 208 is also in an active state. The hinge assembly can be in a fully active state and can be adjusted at any time according to complex transportation conditions, thus enhancing the flexibility of use.

[0036] like Figure 3 As shown, the hinge assembly can also be quickly locked to fix the angle between the upper body support 201 and the lower body support 202. The specific solution is as follows:

[0037] The aforementioned sliding pin 206 is movable in the outward direction to fit into the guide hole 207 without extending outward beyond the guide hole 207. The sliding pin 206 has an internal threaded hole 206a with the opening facing outward. The hinge assembly includes a locking member 209, which has a thicker threaded head 209a and a thinner locking stud portion 209b.

[0038] When it is necessary to lock the angle between the upper support 201 and the lower support 202, the screw head 209a is fixed against the outside of the lower support 202, and the locking stud 209b is inserted into the internal screw hole 206a.

[0039] In short, the locking element 209 can be tightened to fix the angle between the upper body support 201 and the lower body support 202.

[0040] To prevent the locking element 209 from falling off, the locking element 209 is equipped with a connecting rope 210, and the locking element 209 is connected to the lower body support 202 through the connecting rope 210.
