Description

Technical Field

[0001] This invention relates to the field of medication feeding devices, and in particular to a medication feeding device for pediatric care. Background Technology

[0002] Because young children are often unaware of the risks, they may struggle or resist during medication administration, increasing the burden on medical staff and families while wasting medication. To address this, medication feeders were designed to overcome the limitations of spoon-feeding. With advancements in nursing techniques, medication feeders have undergone continuous improvements, incorporating functions such as medication heating. However, they still cannot monitor a child's physiological responses during administration, leading to risks such as oral discomfort from excessively rapid administration or forced medication when a child refuses. These feeders present significant safety risks. Summary of the Invention

[0003] To address the technical problem that the safety of medication administration cannot be guaranteed in existing technologies, the pediatric nursing medication administration device proposed in this invention includes a liquid storage module and a delivery control module, wherein the liquid storage module is disposed above the delivery control module;

[0004] The liquid storage module includes a medicine storage tank, a sugar water storage tank, a medicine delivery valve, a sugar water delivery valve, a camera module, a music player, and a handle. The medicine storage tank is connected to the medicine delivery valve, and the sugar water storage tank is connected to the sugar water delivery valve. Both the medicine delivery valve and the sugar water delivery valve are connected to a liquid delivery pipe.

[0005] The delivery control module includes a liquid transfer storage tank, a delivery pump, a first recovery pump, a temporary storage tank, a second recovery pump, an end cap, a feeding nozzle, a millimeter-wave radar sensor, and a processor. The first input end of the liquid transfer storage tank is connected to the liquid delivery pipe, the second input end is connected to the temporary storage tank through the second recovery pump, and the output end is connected to the end cap through the delivery pump. The end cap is connected to the temporary storage tank through the first recovery pump, and the feeding nozzle is installed on the end cap.

[0006] Preferably, an electric heating film is arranged around the outer wall of the liquid transfer storage tank, a first temperature sensor and a second temperature sensor are respectively arranged at the left and right ends of the inner wall of the liquid transfer storage tank, and a first photoelectric liquid level sensor is arranged at the upper end of the inner wall of the liquid transfer storage tank.

[0007] Preferably, a second photoelectric liquid level sensor is provided on the upper end of the inner wall of the temporary storage tank.

[0008] Preferably, a first liquid level sensor, a second liquid level sensor, and a third liquid level sensor are arranged from bottom to top inside the end cap.

[0009] Preferably, the millimeter-wave radar sensor includes a detection control module, a positioning camera, a position adjustment device, and a detection module. The positioning camera is located to the right of the detection control module, the position adjustment device is connected between the detection control module and the detection module, and the detection module uses FMCW millimeter-wave radar.

[0010] Preferably, the processor operates in three states: normal delivery state, calm delivery state, and emergency processing state.

[0011] Preferably, the switching process of the working state is as follows: the processor receives radar signals from the millimeter-wave radar sensor, analyzes the radar signals to determine whether the movement state of the swallowing muscle group is normal. If it is normal, it enters the normal delivery state. If an abnormality occurs, the camera module is activated to acquire real-time facial video of the child. Based on whether the child coughs and his / her facial color, it is determined whether there is choking. If there is no choking, it enters the soothing delivery state. If there is choking, it enters the emergency treatment state.

[0012] Preferably, under normal delivery conditions, the presence of medication in the temporary storage tank is determined by the second photoelectric liquid level sensor. If medication is present, the medication delivery valve and the sugar water delivery valve are closed, and the second recovery pump is started. The liquid transfer storage tank receives the medication from the temporary storage tank through the second input terminal. If no medication is present, the medication delivery valve is opened, and the sugar water delivery valve and the second recovery pump are closed. The liquid transfer storage tank receives the medication from the storage module through the first input terminal. The liquid transfer storage tank heats the received medication, and after heating, the medication is delivered by the delivery pump to the medication buffer zone formed by the end cap and the feeding nozzle for the child to suck.

[0013] Preferably, in the soothing delivery state, specific music is played through the music player, the delivery pump is turned off, and the first recovery pump is started. The medicine in the medicine buffer formed by the end cap and the feeding nozzle is absorbed into the temporary storage tank until the liquid level in the medicine buffer is lower than the second liquid level sensor. At the same time as starting the first recovery pump, the sugar water delivery valve is opened, and the medicine delivery valve and the second recovery pump are closed. The liquid transfer storage tank heats the received sugar water. After the heating treatment is completed and the liquid level in the medicine buffer meets the requirements, the delivery pump is turned on to deliver the sugar water to the medicine buffer.

[0014] Preferably, in an emergency situation, an alarm is issued through the music player, the medicine delivery valve, the sugar water delivery valve, the delivery pump and the second recovery pump are closed, and the first recovery pump is started to absorb the medicine in the medicine buffer formed by the end cap and the feeding nozzle into the temporary storage tank until the liquid level of the medicine in the medicine buffer is lower than the first liquid level sensor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By combining millimeter-wave radar sensors and camera modules, the system monitors the child's real-time performance during medication administration and adjusts the medication delivery method accordingly to ensure the safety of the process. Attached Figure Description

Detailed Implementation

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, the pediatric nursing medication feeding device proposed in this invention includes a liquid storage module 1 and a delivery control module 2, with the liquid storage module 1 positioned above the delivery control module 2.

[0021] The liquid storage module 1 includes a medicine storage tank 101, a sugar water storage tank 102, a medicine delivery valve 103, a sugar water delivery valve 104, a camera module 105, a music player 106, and a handle 107. The medicine storage tank 101, sugar water storage tank 102, medicine delivery valve 103, and sugar water delivery valve 104 are located inside the liquid storage module 1. The medicine storage tank 101 is connected to the medicine delivery valve 103, and the sugar water storage tank 102 is connected to the sugar water delivery valve 104. Both the medicine delivery valve 103 and the sugar water delivery valve 104 are connected to a liquid delivery pipe 108. The camera module 105 and the music player 106 are located on the right side of the outer casing of the liquid storage module 1, and the handle 107 is located on the left side of the outer casing of the liquid storage module 1.

[0022] The delivery control module 2 includes a liquid transfer storage tank 201, a delivery pump 202, a first recovery pump 203, a temporary storage tank 204, a second recovery pump 205, an end cap 206, a feeding nozzle 207, a millimeter-wave radar sensor 208, and a processor 209. The transfer storage tank 201, delivery pump 202, first recovery pump 203, temporary storage tank 204, second recovery pump 205, and processor 209 are located inside the delivery control module 2. The end cap 206 and feeding nozzle 207 are located at the right end of the delivery control module 2. The millimeter-wave radar sensor 208 is located at the lower end of the delivery control module 2 housing, near the end cap 206. The first input end of the liquid transfer storage tank 201 is connected to the liquid delivery pipe 108, the second input end is connected to the temporary storage tank 204 through the second recovery pump 205, the output end is connected to the end cap 206 through the delivery pump 202, the end cap 206 is connected to the temporary storage tank 204 through the first recovery pump 203, and the drug feeding nozzle 207 is installed on the end cap 206.

[0023] The liquid transfer and storage tank 201 is used to store medicinal liquids or sugar water. An electric heating film 2011 is arranged around the outer wall of the liquid transfer and storage tank 201. A first temperature sensor 2012 and a second temperature sensor 2013 are respectively installed at the left and right ends of the inner wall of the liquid transfer and storage tank 201. A first photoelectric liquid level sensor 2014 is installed at the upper end of the inner wall of the liquid transfer and storage tank 201. The liquid transfer and storage tank 201 operates by receiving medicinal liquids or sugar water through a first input terminal or a second input terminal. During the receiving process, the first photoelectric liquid level sensor 2014 monitors the liquid level in real time. When the liquid level reaches a set threshold, the medicinal liquid delivery valve 103 and the sugar water delivery valve 104 are closed, causing the second recovery pump 205 to stop working. The electric heating film 2011 is then activated to heat the liquid in the liquid transfer and storage tank 201. The first temperature sensor 2012 and the second temperature sensor 2013 monitor the liquid temperature in real time. When the temperature reaches a set value, the delivery pump 202 is activated to deliver the liquid to the end cap 206.

[0024] A second photoelectric liquid level sensor 2041 is installed on the upper inner wall of the temporary storage tank 204 to monitor changes in the internal liquid level in real time.

[0025] The end cap 206 and the feeding nozzle 207 together form a medicine buffer zone, ensuring a gentle delivery of the medicine, which the child obtains by sucking. Inside the end cap 206, from bottom to top, are a first liquid level sensor 2061, a second liquid level sensor 2062, and a third liquid level sensor 2063, which monitor the liquid level in the medicine buffer zone in real time and perform corresponding control operations based on the liquid level.

[0026] The millimeter-wave radar sensor 208 includes a detection and control module 2081, a positioning camera 2082, a position adjustment device 2083, and a detection module 2084. The positioning camera 2082 is located to the right of the detection and control module 2081. The position adjustment device 2083 is connected between the detection and control module 2081 and the detection module 2084. The detection module 2084 uses FMCW millimeter-wave radar. The positioning camera 2082 captures an image of the child's throat and neck. The detection and control module 2081 determines the specific location of the swallowing muscles based on the image and adjusts the position adjustment device 2083 so that the detection module 2084 is directly facing the swallowing muscles. The movement of the swallowing muscles is detected during medication administration using radar signals.

[0027] The processor 209 controls the operation of the delivery control module 2. The processor 209 operates in three states: normal delivery, soothing delivery, and emergency handling. In normal delivery, the second photoelectric liquid level sensor 2041 determines whether there is medication inside the temporary storage tank 204. If medication is present, the medication delivery valve 103 and the sugar water delivery valve 104 are closed, and the second recovery pump 205 is activated. The liquid transfer storage tank 201 receives the medication from the temporary storage tank 204 through its second input terminal. If no medication is present, the medication delivery valve 103 is opened, and the sugar water delivery valve 104 and the second recovery pump 205 are closed. The liquid transfer storage tank 201 receives the medication from the storage module 1 through its first input terminal. The liquid transfer storage tank 201 heats the received medication, and after heating, the medication is delivered by the delivery pump 202 to the medication buffer zone formed by the end cap 206 and the feeding nozzle 207 for the child to suck. In the soothing delivery state, specific music is played through music player 106 to psychologically soothe the child. Delivery pump 202 is turned off, and first recovery pump 203 is started to absorb the medicine in the medicine buffer into temporary storage tank 204 until the liquid level in the medicine buffer is lower than the second liquid level sensor 2062. At the same time as starting the first recovery pump 203, sugar water delivery valve 104 is opened, and medicine delivery valve 103 and second recovery pump 205 are closed. Liquid transfer storage tank 201 heats the received sugar water. After the heating treatment is completed and the liquid level in the medicine buffer meets the requirements, delivery pump 202 is turned on to deliver sugar water to the medicine buffer, improving the taste of the medicine and physiologically soothing the child. Through psychological and physiological soothing, the child no longer resists drinking medicine. In emergency situations, an alarm is triggered via the music player 106, closing the medication delivery valve 103, the sugar water delivery valve 104, the delivery pump 202, and the second recovery pump 205. The first recovery pump 203 is activated to draw medication from the medication buffer into the temporary storage tank 204 until the medication level in the buffer is below the first level sensor 2061. The state switching process involves the processor 209 receiving radar signals from the millimeter-wave radar sensor 208, analyzing the radar signals to determine if the swallowing muscle movement is normal. If normal, it enters the normal delivery state. If an abnormality occurs, the camera module 105 is activated to acquire real-time facial video of the child. Based on whether the child coughs and their facial expression, it is determined whether choking has occurred. If no choking occurs, it enters the soothing delivery state. If choking occurs, it enters the emergency treatment state.

[0028] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. It should be noted that any equivalent variations made to the present invention by those skilled in the art without departing from its design structure and principles are considered within the scope of protection of the present invention.
