Description

Patient transfer inflatable device

technical field

The invention relates to the technical field of medical equipment, in particular to an inflatable device for patient transfer.

Background technique

Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software. The utility is mainly obtained through physical means, not through Obtained by means of pharmacology, immunology or metabolism, or although these methods are involved but only play an auxiliary role, for the purpose of diagnosis, prevention, monitoring, treatment or alleviation of diseases; diagnosis, monitoring, treatment, alleviation or functional compensation of injuries; Examination, substitution, regulation or support of physiological structures or processes; support or maintenance of life; pregnancy control; providing information for medical or diagnostic purposes by examining samples from the human body.

In the prior art, such as Chinese patent application number: CN111419591 A discloses a kind of inflatable cushion device for human body transfer, including a square air mattress detachably installed on the bed body, wherein the height of the bottom of the air mattress is equal to the bed of the transfer bed The height of the panel, the air mattress is provided with straps for fixing the human body on the air mattress, and the two sides of the air mattress are provided with handles for moving the air mattress. When the human body is on the hospital bed and does not need to be transferred, the air mattress To maintain the compressed state, when the human body needs to be transferred from the hospital bed to the transfer bed, the air mattress needs to be inflated to make the air mattress change from the compressed state to the expanded state. Compared with the prior art, the present invention provides handles on the air mattress, binds the human body to the air mattress, and can quickly, conveniently and safely transfer the human body by pulling the air mattress by a single person.

But there is following deficiency in above-mentioned patent:

The inflatable transfer mattress is used in conjunction with the ferry frame. It is mainly due to the transfer of the patient after the operation. Because the surface of the inflatable mattress is relatively soft, the patient's physical fitness is relatively weak after the operation and the disease cannot be carried by a large scale. At this time, by using The inflatable mattress can prevent the patient from being damaged by external forces during the transfer process to the greatest extent, and the device involved in the above patent, due to the singleness of the internal structure, after the patient uses the inflatable mattress to move to the designated bed, the air mattress is deflated , and then forcefully withdraw the mattress from the patient's back, and the compressed mattress itself has a moving height. At the same time, the bed is covered with a sheet, and the friction between the mattress and the sheet is too large under the action of gravity, and it is pulled slowly. For the mattress, the patient is also in relative motion and cannot leave the mattress. If the mattress is pulled away too fast, the patient’s body will fall directly onto the bed, and the device still needs to carry the patient’s body during the process of transferring the patient to the hospital bed. .

So we propose a patient transfer inflatable device to solve the problems mentioned above.

Contents of the invention

The purpose of the present invention is to provide an inflatable device for patient transfer. When the device and the patient move to the bed, the exhaust valve is opened, and the gas stored in the nylon cushion is continuously discharged, and finally it returns to the original thickness, and the force is applied sequentially. Pull the metal plug out of the hollow shell, and apply an external force to one side of the air mattress, and then apply an opposite force to the side of the nylon cushion. Because the contact area between a set of rollers and the bed surface is small, use Due to the movable connection of the rollers and the support frame, the air mattress and its connected parts slowly move out of the bed, while the patient on the nylon cushion finally breaks away from the entire device and stays on the bed.

In order to achieve the above object, the present invention provides the following technical solutions: a patient transfer inflatable device, including an air mattress, the front surface of the air mattress is fixedly connected with an exhaust valve, and the bottom of the air mattress is provided with an air triggering mechanism;
