Description

Technical Field

[0001] The invention relates to a liquid food feeding technology through a gastric tube, and in particular to an intelligent liquid food feeding and nursing machine. Background Art

[0002] For patients with gastric tube insertion, liquid food needs to be injected into the gastric tube for feeding. The current insertion operation process is as follows: 1. Open the gauze wrapped around the gastric tube head, connect the syringe, and extract gastric juice to determine whether feeding is possible.

[0003] 2. After confirming that the baby can be fed, use a large syringe or liquid food booster to fill it with liquid food, then push out a little bit and feel the temperature on the back of your hand. It should feel neither hot nor cold, that is, around 37-40℃, and then slowly push it into the gastric tube manually.

[0004] 3. During the pushing process, the patient's status should be monitored. If any abnormality occurs, stop immediately. If no abnormality occurs, continue pushing until the corresponding feeding amount is reached. Currently, the feeding amount is about 300 ml each time, and the feeding time is 15-30 minutes. Generally, the interval between each feeding is about 3 hours. Some nursing care requires multiple feedings in small amounts, so the feeding amount may be about 100 ml each time, and the interval is about 2 hours.

[0005] 4. After feeding, you need to inject about 50 ml of warm water with a temperature of about 37-40°C into the stomach tube to clean the stomach tube. Finally, remove the large syringe or liquid food booster, wrap the end of the stomach tube with gauze, and complete the feeding care.

[0006] From the above nursing process, it can be seen that the entire feeding process takes at least 20 minutes for a nurse, which obviously seriously consumes nursing resources and increases the nursing burden. At the same time, it is impossible for the accompanying staff to operate because it involves temperature, speed, and patient performance observation.

[0007] With the development of automation, intelligence, and artificial intelligence technology, the liquid feeding process is actually a very standardized process, and the current artificial intelligence technology can completely monitor the patient's status during the liquid feeding process by combining the patient's worn monitoring equipment and the patient's body image, sound, and expression recognition.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0022] See also Figure 1-Figure 5 The intelligent liquid food feeding and nursing machine of this embodiment includes a housing 110 and a cabinet door 120. A universal wheel 140 is installed at the bottom of the housing 120, and the universal wheel 140 is used to facilitate the movement of the entire device. One side of the cabinet door 120 is hinged to the housing 110 through a hinge 130. The cabinet door 120 is provided with a handle 121 and a door slot 122 that penetrates the cabinet door 120. The handle 121 is used to facilitate the opening and closing of the cabinet door 120.

[0023] A buckle 150 is also installed inside the housing 110. A buckle sheet 151 is installed on the buckle 150. A buckle protrusion 152 is installed on the buckle sheet 151. The buckle sheet 151 is elastic and keeps the buckle protrusion 152 in an open state. After the buckle protrusion 152 passes through the door groove 122, it opens under the elastic force of the buckle sheet 151 so that the buckle protrusion 152 is clamped on the outer side of the door groove 122 to lock the door panel 120. When in use, it is only necessary to apply a certain rotational force to the door panel 120 so that the edge of the door groove 122 presses the buckle protrusion 152 so that the buckle protrusion enters the door groove 122 to open the door panel 120.

[0024] See also Figure 1-Figure 8 A placement rack 160 , a storage module 300 , a switch module 400 , and a pumping module 200 are installed in the housing 110 . A card strip 161 is installed on the placement rack 160 , and a card slot 162 is provided on the card strip 161 .

[0025] The storage module 300 includes a storage shell 310, an insulation cloth 320, a first transverse plate 331, a second transverse plate 332, an elastic strip 340, and an elastic band 350. The storage shell 310 is provided with a storage shell groove 311. The first transverse plate 331 and the second transverse plate 332 are respectively installed on the storage shell 310, and the first transverse plate 331 is assembled and fixed to one end of the insulation cloth 320, and the other end of the insulation cloth 320 is fixed to the second transverse plate 332. The insulation cloth 320 is made of insulation cloth, and the inner wall of the storage shell 310 is sprayed with insulation material.

[0026] In this embodiment, one end of the insulation cloth 320 can be assembled and fixed to the first horizontal plate 331, and the other end can be bonded and fixed to the second horizontal plate 332 through the tear buckle, and the second horizontal plate 332 and the insulation cloth 320 respectively fix the hook surface and the fleece surface of the tear buckle. This design greatly facilitates the opening and closing of the insulation cloth 320, thereby facilitating the loading and unloading of food bags.

[0027] The storage shell slot 311 is clamped on the clamping strip 161 and in the clamping slot 162, so as to realize the installation of the storage shell 310, and the storage shell 310 can be removed and installed as needed during use.

[0028] There are four elastic strips 340 and the elastic strips 340 have elastic force. The elastic band 350 has elasticity. The elastic band 350 passes through the four elastic strips 340 and is assembled and fixed therewith. The four elastic strips 340 are respectively clamped on the outer side of the liquid food belt 710 to clamp and fix the liquid food belt 710. Figure 8 In the initial state, the two elastic strips 340 on the left and the two elastic strips 340 on the right want to approach each other under the action of their own elastic force to clamp the food bag 710. When the food bag 710 shrinks, the elastic strips 340 flexibly adapt through their own elastic force.

[0029] The storage shell 310 is provided with a heating plate 370 and a temperature sensor 360. The heating plate 370 has a built-in heating wire. When the heating wire is powered on, it generates heat to heat the inside of the storage shell 310, thereby heating the food bag 710. The temperature sensor 360 is used to detect the ambient temperature inside the storage shell 310 to assist in determining whether the food bag 710 needs to be heated. The signal of the temperature sensor is connected to the industrial computer. A relay is connected in series to the power supply circuit of the heating wire, and the control end of the relay is connected to the industrial computer. Generally, the temperature of liquid food is around 38°C. Once the temperature detected by the temperature sensor 360 is lower than 36°C, it means that the liquid food needs to be heated. At this time, the relay is started to heat the inside of the storage shell 310 until the temperature detected by the temperature sensor 360 reaches 38°C and then stops. This design can maintain the temperature of the liquid food or warm water in the food bag 710 to avoid irritating the patient due to low temperature.

[0030] The storage shell 310 and the card strip 161 may be provided with a socket and a plug respectively, and the socket and the plug are connected and conductive, so as to supply power to the heating plate 370 and the temperature sensor 360 and connect the signal of the temperature sensor 360 to the industrial computer.

[0031] The storage module 300 has two food bags 710, one for storing liquid food, and the other for storing warm water. One of the food bags 710 is connected to one end of the delivery tube 720, and the other food bag 710 is connected to one end of the delivery branch tube 721, and the other end of the delivery branch tube 721 is connected to the delivery tube 720, and the other end of the delivery tube 720 is connected to one end of the pump tube 730, and the other end of the pump tube 730 is connected to one end of the output tube 740, and the other end of the output tube 740 is used to connect to the stomach tube to input liquid food and water into the stomach tube.

[0032] The delivery pipe 720 and the delivery branch pipe 721 correspond to a switch module 400 for controlling the on and off thereof, respectively. The switch module 400 includes an electric cylinder 410, a movable seat 420, and a fixed seat 430. The electric cylinder shaft 411 of the electric cylinder 410 is assembled with the movable seat 420. The electric cylinder 410 is installed and fixed in the housing 110, and the movable seat 420 can move relative to the housing 110. An extrusion block 421 is provided on the movable seat 420. The extrusion block 421 can squeeze the delivery pipe 720 or the delivery branch pipe 721 toward the heat transfer block 450, thereby cutting off the inside of the delivery pipe 720 or the delivery branch pipe 721 to achieve closure. When the extrusion block 421 does not squeeze the delivery pipe 720 or the delivery branch pipe 721, the delivery pipe 720 or the delivery branch pipe 721 is restored to be connected by its own elastic force.

[0033] The fixing seat 430 is installed in the shell 110, and a slide groove 431 is provided inside the fixing seat 430. The heat-conducting block 450 is engaged and slidably installed in the slide groove 431. The heat-conducting block 450 is assembled with one end of the catheter 460. The other end of the catheter 460 is installed with a catheter seat 461, and the catheter spring 401 is installed on the catheter to pass through the end plate 440, and the end plate 440 is installed on the fixing seat 430; the heat-conducting block 450 is made of a material with a high thermal conductivity coefficient, such as copper, aluminum alloy, carbon fiber, etc., and a first temperature probe 470 is pasted and fixed on the heat-conducting block 450. The power connection end of the first temperature probe 470 is electrically connected to the access end of the delivery temperature sensor through the first wire 471, so that the delivery temperature sensor detects the temperature of the delivery pipe 720 or the delivery branch pipe 721 through the first temperature probe 470 to determine whether the temperature is suitable for feeding. Of course, there will be a large error between the temperature detected here and the temperature of the fluid in the delivery pipe 720 or the delivery branch pipe 721, but this error can be obtained through a limited number of tests, and the error compensation method with the actual temperature can be calculated, and then the measurement accuracy can be greatly improved by using this error compensation. At the same time, the feeding temperature is in the range of about 37-40℃, so the tolerance for error is also very high.

After the motor 520 is started, it can drive the worm 650 to rotate, thereby driving the worm wheel to rotate, so as to drive the drive disk 620 to rotate, so that the extrusion wheel intermittently squeezes the pump tube 730 to generate a suction force inside the pump tube 730, so as to transport the fluid in the delivery tube 720 to the output tube 740, or transport the fluid in the output tube 740 to the delivery tube 720. The peristaltic pump of this embodiment can directly adopt the existing product without being restricted to the above structure.

[0044] In some embodiments, the portion of the delivery pipe 720 between the connecting point of the delivery pipe 720 and the delivery branch pipe 721 and the connecting point of the delivery pipe 720 and the pump pipe 730 also passes through a photoelectric sensor, wherein the photoelectric sensor includes a first transmitter 511 and a first receiver 512. The first transmitter 511 and the first receiver 512 are both installed in a housing and their signals are connected to an industrial computer. The first transmitter 511 emits light to the first receiver 512. Once there is no liquid food or water at the corresponding position of the delivery pipe 720, the signal of the first receiver 512 will change, thereby determining that there is no liquid food or water in the delivery pipe 720.

[0045] When in use, the first temperature probe 470 is used to detect the temperature of the outer wall of the delivery tube 720. If the temperature is low, such as below 34°C, the heat conductive wire is energized to generate heat, and the air pump is started to blow air to blow hot air to the pump tube 730 to heat the fluid in the pump tube. The second temperature probe 540 detects the temperature of the outer wall of the output tube 740. Once it reaches 36°C, it can be considered that the heating has been completed, and it can be delivered to the stomach tube. If the heating temperature is not reached or the heating temperature is too high, the motor intermittently rotates forward and reversely so that the fluid is reversely drawn into the pump tube 730 and flows repeatedly until it reaches a suitable temperature. When the temperature detected by the first temperature probe 470 is too high, such as above 40°C, the heat conductive wire is not enabled and the air pump is directly started to blow air until the temperature detected by the second temperature probe 540 reaches about 36°C and then delivered to the stomach tube. The above temperature is only a reference and can be adjusted according to actual conditions in practice, and is not a limitation of this application.

[0046] The usage of this embodiment is as follows: S1, put liquid food in one food bag 710 and warm water in another food bag 710, and then install the two food bags 710. The two switch modules keep the delivery pipe 720 and the delivery branch pipe 721 in a state of being compressed and cut off.

[0047] S2. Medical staff push the device to the patient's bedside, then extract gastric juice through the gastric tube to confirm that feeding is possible.

[0048] S3, connect the output tube 740 with the stomach tube, set the feeding speed, temperature and other parameters, and then start the electric cylinder 410 corresponding to the food bag 710 containing the liquid food, so that it opens the corresponding delivery tube 720 or delivery branch tube 721; start the motor to start feeding.

[0049] S4, when the photoelectric sensor detects that the feeding of liquid food is completed, the switch module corresponding to the food bag 710 containing the liquid food is closed, and the other switch module is opened to input warm water into the pump tube 730 until the corresponding amount is reached, and the switch module is closed to complete the cleaning of the stomach tube. Then the medical staff can remove the stomach tube, and then replace the food bag, delivery tube, pump tube, and output tube for the next patient.

[0050] In this embodiment, the liquid food can be first loaded into the food bag, so that it can be quickly replaced to increase efficiency, or it can be loaded in advance by family members, care workers, canteens, etc. and handed over to medical staff for feeding. The motor can also be reversed to insert the output tube into the liquid food and then the liquid food can be reversely input into the corresponding food bag for storage and subsequent feeding. In addition, the peristaltic pump has a stable flow output function, that is, it has a metering effect. When used, it is completely possible to measure its delivery amount each time, that is, the delivery amount of the drive disk 620 rotating one circle, so as to control the feeding speed and feeding amount by controlling the rotation speed of the drive disk 620. In some scenes where multiple small amounts of feeding are required, the feeding amount, feeding speed, etc. can be set each time, and automatic and intelligent feeding can be controlled by program. At the same time, the heating plate and the temperature sensor are used to keep the water and liquid food in the food bag warm. Embodiment 2

[0051] See also Figure 14-Figure 22 In the first embodiment, the switch module 400 is fixed in the housing 110, and then the delivery pipe 720 and the delivery branch pipe 721 are controlled to be on and off. The food bag 710 needs to be opened during installation, and then loaded into the corresponding storage module 300, and then the delivery pipe 720 and the delivery branch pipe 721 are connected. During this process, the liquid food or water in the food bag will flow out and cause pollution. Therefore, the present embodiment is improved as follows: the storage module 300 for storing warm water is removed and replaced with a thermos bottle 750 with a heat preservation function to store warm water. The heat preservation function of the thermos bottle 750 is used without adding additional heating and temperature detection equipment. A ball valve is added to the thermos bottle to control its on and off, thereby replacing the corresponding switch module 400. The switch module 400 is designed to have a power part installed on the placement rack 160 and a switch function part designed on the storage shell 310, so that when the food bag 710 is installed, the opening can be facing upward and then connected to the delivery pipe 720, and then the delivery pipe 720 is closed by using the switch module 400, and finally the storage module 300 is installed on the placement rack 160. The whole process can achieve that the liquid food in the food bag will not flow out and cause pollution, and it is also more convenient to use.

[0052] The specific improved structure is as follows: Two groups of card seats are installed on the placement rack 160, each group of card seats includes two card seats 170, and the inner side of the card seat 170 is provided with a card seat groove 171, and the two card seats 170 of each group of card seats are respectively installed on both sides of the yield groove 163 and the placement rack 160, the yield groove 163 is arranged on the placement rack 160 and passes through the placement rack 160, and the second transmitter 591 and the second receiver 592 are respectively installed on both sides of the yield groove 163, and the second transmitter 591 emits light to the second receiver 592, and the two yield grooves 163 pass through the conveying pipe 720 and the conveying branch pipe 721 respectively, and the two pairs of second transmitters 591 and second receivers 592 are respectively located on both sides of the corresponding conveying pipe 720 and the conveying branch pipe 721. During use, the light received by the second receiver 592 is blocked due to the fluid inside the delivery pipe 720 and the delivery branch pipe 721. Once there is no fluid at the corresponding parts of the delivery pipe 720 and the delivery branch pipe 721, the light will pass through the delivery pipe 720 and the delivery branch pipe 721, so that the second receiver 592 receives the light and then inputs a signal to the industrial computer. The industrial computer determines that the fluid in the corresponding delivery pipe 720 or delivery branch pipe 721 has flowed out.

[0053] A switch seat 480 is installed on the storage shell 310, and a switch seat groove 481 is set on the switch seat 480. The delivery pipe 720 is inserted into the switch seat groove 481 and the two sides of the delivery pipe 720 are respectively pressed or pressed against the detection block 482 and the movable block 870. The detection block 482 is installed and fixed on the switch seat 480 and the detection block 842 is made of a high thermal conductivity material. A fixed temperature probe 504 is pasted and fixed on the detection block 842. The signal of the fixed temperature probe 504 is connected to the fixed temperature sensor so that the fixed temperature sensor detects the temperature of the detection block 842 through the fixed temperature probe 504, that is, the temperature of the outer wall of the delivery pipe 720. The function here is the same as that of the first temperature probe 470 in Example 1.

[0054] The movable block 870 is engaged and slidably installed in the movable groove 483, which is set on the switch seat 480, and the movable block 870 is assembled with one end of the movable shaft 880. The other end of the movable shaft 880 is sleeved with the movable spring 402 and then passes through the switch seat 480 and is assembled with the limit nut 881 and the end ring 882 respectively. The limit nut 881 cannot pass through the switch seat 480 to limit the maximum displacement of the movable shaft 880 to the fixed block 482. The movable spring 402 applies an elastic force to the movable block 870 to push the fixed block 482, so that in the initial state, the movable block 870 presses the delivery tube 720 toward the fixed block 482 to close the inside of the delivery tube 720 to achieve the closure of the delivery tube 720.

[0055] The end ring 882 can be installed in the switch member slot 861 of the switch member 860. The switch member 860 is installed on one end of the switch electric cylinder shaft 581, and the switch electric cylinder 580 is installed on the placement frame 160. When in use, the switch electric cylinder 580 drives the switch electric cylinder shaft 581 to move axially, thereby driving the movable block 870 to move through the switch member 860 to realize the closing and opening of the conveying pipe 720.

[0056] The storage shell 310 is installed on the first movable seat 810, and the two sides of the first movable seat 810 are respectively inserted into the corresponding seat grooves 171 to realize the detachable assembly of the storage module 300 and the placement rack 160. This method allows the end ring to move relative to the switch slot 861 when the storage module 300 is disassembled and assembled, so that it is convenient to use. This design allows the opening of the food bag 710 to face upward when the food bag 710 is installed, and then the delivery pipe is connected and the movable block is used to squeeze the delivery pipe 720 to achieve the closure of the delivery pipe, and then the storage module 300 is installed. When the storage module is installed, the end ring 882 is inserted into the switch slot 861.

[0057] Preferably, a plug connector is also installed on the storage shell 310 , and the plug connector is inserted into the socket 503 to realize power supply and communication for the storage module, and the socket 503 is installed on the placement rack 160 .

[0058] The bottle mouth 751 of the thermos bottle 750 is installed in the valve water inlet pipe 762 and is fixed and sealed therewith. The valve water inlet pipe 762 is installed in the ball valve 760. A ball 761 is installed in the ball valve 760. The ball 761 is provided with a ball hole 7611 and a side hole 7612. The ball hole 7611 can connect the valve water inlet pipe 762 and the valve water outlet pipe 763. The valve water outlet pipe 763 is installed on the ball valve. One end of the side hole 7612 is connected to the ball hole 7611 and the other end is installed with a one-way pipe 764. A one-way valve 501 is installed in the one-way pipe 764. The one-way valve 501 can suck external air into the side hole 7612, thereby replenishing the air pressure in the thermos bottle 750.

[0059] The sphere 761 is respectively assembled and fixed to one end of the one-way tube 764 and one end of the valve stem 765. The one-way tube 764 and the valve stem 765 are respectively assembled to the ball valve so that they can rotate in a circular motion. The other end of the valve stem 765 passes through the ball valve 760 and is assembled and fixed to the clutch head 7651. The clutch head 7651 is installed in the clutch sleeve 841 and the end face of the clutch head 7651 is pressed and driven against the end face of the clutch shaft 840. The clutch shaft 840 is installed in the driving tube 850 and is assembled thereto so that it can slide axially but cannot rotate relative to the circumference, such as by splines or spline grooves. The driving tube 850 is installed on the placement frame 160 so that it can rotate in a circular manner but cannot move axially. A spring ring 842 is also provided on the clutch shaft 840. A clutch spring 801 is mounted on the portion of the driving tube 850 between the placement frame 180 and the spring ring 842. The two ends of the clutch spring 801 are respectively assembled and fixed to the placement frame 180 and the spring ring 842, and the clutch spring applies an elastic force to the clutch shaft to press the clutch head to ensure the compression transmission between the clutch head and the clutch shaft.

[0060] The driving tube 850 is fitted with a clutch worm wheel 891, which is meshed with a clutch worm 892 for transmission. The clutch worm 892 is arranged on the valve motor shaft 571, and the valve motor shaft 571 is installed in the valve motor 570, and the valve motor 570 is installed on the placement rack 160. The driving tube 850 is also assembled with the input shaft of the encoder 502, and the housing of the encoder 502 is installed on the placement rack 160. When in use, the encoder detects the rotation angle of the driving tube 850, thereby determining the switch of the ball valve 760.

[0061] The ball valve 760 is inserted into the ball valve seat groove 771, the ball valve seat groove 771 is arranged on the ball valve seat 770, the ball valve seat 770 is installed on the corresponding second movable seat 830, and the second movable seat 830 and the ball valve seat 770 are also installed with a water pipe 820, one end of the water pipe 820 is connected to the valve outlet pipe 763, and the other end is connected to the delivery branch pipe 721. Both sides of the second movable seat 830 are inserted into the corresponding seat grooves 171 so that the second movable seat 830 can be quickly disassembled.

[0062] When in use, the valve motor is used to control the on and off of the ball valve to control the water supply and water cutoff of the delivery branch pipe. When water needs to be added to the thermos bottle, the thermos bottle and the ball valve are removed, and then the ball valve is removed to add water to the thermos bottle.

[0063] In this embodiment, a wireless module and an industrial computer can be installed in the shell, a three-axis pan-tilt 561 is installed on the top of the shell, and a camera 560 is installed on the three-axis pan-tilt 561. The wireless module is connected to the hospital intranet, and the nursing equipment worn by the patient is also connected to the hospital intranet. The hospital intranet is connected to the nursing system and the server. The information detected by the monitoring equipment worn by the patient is uploaded to the server, and the image of the patient obtained by the camera is also uploaded to the server. The server uses image recognition technology, facial recognition technology, artificial intelligence technology, etc. combined with the physiological data collected by the monitoring equipment to judge the patient's status. Once the status is abnormal during feeding, the feeding is stopped immediately and the nursing staff is notified to handle it in time. Of course, without adding the above scheme, the accompanying personnel can observe the patient's reaction and status, and notify the medical staff in time to handle it if there is any abnormality.

[0064] Of course, a camera can also be added inside the output tube to collect the image of gastric fluid pumped into the output tube (peristaltic pump reverse suction), so as to identify and determine whether feeding is possible. In this way, the accompanying personnel can complete the feeding by themselves, which greatly releases nursing resources and ensures the safety of the patient. The accompanying personnel and nursing staff only need to install or replace the food bag to ensure the supply of liquid food and fill the thermos with warm water, which is very time-saving and labor-saving, and is also very convenient to use.

[0065] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0066] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
