Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a self-feedback regulated liquid food feeder. Background Art

[0002] Some users who have undergone severe surgery or have limited mobility can only eat liquid food to supplement energy. For users with normal swallowing function, nasogastric feeding is not required, but caregivers are required to assist in feeding. Traditional liquid food feeding methods usually use syringes to squeeze in, and the temperature and speed of the liquid food are completely controlled by the caregivers. The temperature and speed of squeezing in are difficult to control, and this feeding method is more laborious for caregivers and takes a long time. In order to save caregivers' time and reduce their work intensity, many types of automatic feeders are currently available on the market, most of which use negative pressure or peristaltic pumps to deliver liquid food to the user's mouth.

[0003] However, the existing feeders only directly deliver liquid food to the user's mouth, and cannot automatically adjust the start and stop of liquid food delivery according to the user's swallowing situation. It is easy for the liquid food to continue to be delivered while the user is swallowing, thereby causing the liquid food to overflow. Utility Model Content

[0004] The utility model aims to provide a liquid food supplier with self-feedback regulation to solve the technical problem that the liquid food supplier in the prior art cannot automatically regulate the interruption of liquid food supply according to the swallowing situation of the user.

[0007] When the controller receives a signal exceeding a preset pressure threshold value collected by the pressure sensor, the controller issues a target instruction to control the corresponding peristaltic pump to stop delivering.

[0008] As a preferred solution of the utility model, a protection pad is provided on the outer surface of the pressure sensor, and the protection pad is made of elastic material.

[0009] As a preferred solution of the utility model, the protection pad is configured to be flat, so that the thickness of the protection pad is 2-6 mm.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 and Figure 2 As shown, the present invention provides a self-feedback regulated liquid food feeder, which mainly regulates the interruption of liquid food supply by utilizing the squeezing force between the tongue and the upper palate when the user swallows.

[0020] The self-feedback regulated liquid food feeder comprises a pipe 1 for delivering liquid food to the oral cavity of a user, a feeding port 2 is provided at one end of the pipe 1, a peristaltic pump 3 for providing a delivery power to the pipe 1 is provided on the pipe 1, a pressure sensor 4 is provided on one side of the feeding port 2, the pressure sensor 4 can sense and receive the squeezing force when the tongue of the user contacts the upper palate when swallowing, the pressure sensor 4 is electrically connected to a controller 5, and the controller 5 is electrically connected to the peristaltic pump 3;

[0021] When the controller 5 receives the signal exceeding the preset pressure threshold collected by the pressure sensor 4 , it gives a target instruction to control the corresponding peristaltic pump 3 to stop delivering.

[0022] The existing feeders only directly deliver liquid food to the user's mouth, and cannot automatically adjust the start and stop of liquid food delivery according to the user's swallowing situation. It is easy for the liquid food to continue to be delivered while the user is swallowing, thereby causing the liquid food to overflow. Therefore, it is necessary to develop a liquid food feeder that can automatically adjust the interruption of liquid food supply according to the user's swallowing situation.

[0023] In this embodiment, a pressure sensor 4 is provided at the end of the pipe 1 and placed inside the user's mouth. The pressure sensor 4 is squeezed by making full use of the squeezing force between the tongue and the upper palate when the user swallows, thereby correspondingly controlling the delivery of the liquid food, realizing self-feedback regulation, and being able to better match the swallowing rhythm of the user.

[0024] In actual use:

[0025] First, the feeding port 2 is placed inside the user's mouth, and the other end of the pipe 1 is placed in a container for liquid food, and the pressure sensor 4 is placed above the user's tongue;

[0026] Then the peristaltic pump 3 is started, and the liquid food in the container is transported to the user's oral cavity through the pipe 1;

[0027] When a certain amount of liquid food accumulates in the user's oral cavity, the user will swallow, and the user's tongue will touch the upper palate during swallowing, thereby squeezing the pressure sensor 4;

[0028] The pressure sensor 4 transmits the squeeze pressure signal value collected by it to the controller 5 in real time. When the controller 5 receives the signal collected by the pressure sensor 4 that exceeds the preset pressure threshold, it gives a target instruction to control the corresponding peristaltic pump 3 to stop delivering, so that when the user swallows, the peristaltic pump 3 stops delivering;

[0029] When the user finishes swallowing, his tongue no longer contacts the upper palate, so that the signal value collected by the pressure sensor 4 is less than the preset pressure threshold, and the controller 5 gives a target instruction for the corresponding peristaltic pump 3 to continue conveying, thereby resuming conveying;

[0030] Through the swallowing operation of the user, the delivery and termination of liquid food can be automatically controlled without the need for external personnel to operate, achieving self-feedback adjustment, and can be personalized for individuals.

[0031] In the present utility model, the model of the pressure sensor 4 and the corresponding sensing method and subsequent electrical processing method are widely used in the present technical field. Therefore, the applicant will not elaborate on the specific operation method. However, for the sake of easy understanding, the pressure sensor in the present embodiment is described as follows, but it should be noted that the example is limited to fully describe the specific operation process and does not limit the specific model. For example, the oral pressure measurement device in the publication number CN116942164A.

[0032] As a preferred embodiment of this embodiment, a protection pad 6 is provided on the outer surface of the pressure sensor 4, and the protection pad 6 is made of elastic material. The pressure sensor 4 can be protected by providing the protection pad 6 made of elastic material.

[0033] In order to reduce the foreign body sensation of the pressure sensor 4 and the protective pad 6, the protective pad 6 is set to be flat, so that the thickness of the protective pad 6 is 2-6 mm. The pressure sensor 4 is a force-sensing dot matrix pressure sensor 4. The pressure sensor 4 can be squeezed better when swallowing.

[0034] Furthermore, if Figure 2 As shown, a soft plate 7 is fixedly connected between the protection pad 6 and the feeding port 2, and the soft plate 7 is arranged to be tilted upward, and the soft plate 7 can be curled when being squeezed by an external force. When the pressure sensor 4 is not squeezed by an external force, the pressure sensor 4 is supported by the soft plate 7 so that it is between the upper palate and the tongue, thereby reducing the influence on swallowing.

[0035] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
