Description

Technical Field

[0001] The invention relates to the technical field of feeding assistance, and in particular to a temperature sensing alarm oral feeding assistance drip device. Background Art

[0002] For patients with oral diseases, or those after orthognathic surgery, food and medicine are routinely supplied through a gastric tube to maintain the patient's nutritional and treatment needs. The existing feeding device is a pair of 50 ml syringes, which are used for feeding every 3-6 hours. The amount of food fed at a time is limited, and the feeding tube needs to be reconnected repeatedly for feeding. The feeding time is about 15-20 minutes each time, which is time-consuming and laborious. In addition, the temperature during use cannot be displayed, and it is not easy to grasp the temperature of the feeding fluid. If the feeding fluid is overheated, it may cause burns, causing immeasurable harm to the patient.

[0043] In the above scheme, a U-shaped mounting groove 81 extending up and down is provided through the right end face of the adjusting clamp 8, a U-shaped elastic slide rail 82 is provided in the U-shaped mounting groove 81, an adjusting member 83 is slidably connected in the U-shaped elastic slide rail 82, an adjusting member 83 is connected to the lower end of the adjusting member 83 with an adjusting plate 84, the temperature sensing device 9 is detachably connected to the adjusting plate 84, and an electric clamp 85 is provided in the middle of the left end face of the adjusting clamp 8.

[0044] As an optimized technical solution of the present invention, the U-shaped elastic slide rail 82 is installed in the U-shaped installation groove 81 opened on the right end face of the adjusting clamp 8, and the adjusting member 83 and the adjusting plate 84 are slidably connected in the U-shaped elastic slide rail 82 and connected to each other. The adjusting member 83 can drive the adjusting plate 84 to slide in the U-shaped elastic slide rail 82, and then the position of the temperature sensing device 9 can be adjusted to meet the use requirements of the device. At the same time, the adjusting clamp 8 clamps the adjusting clamp 8 on the fixed frame for fixing the nutrient solution bottle 1 through the electric clamp 85 on its left end face, so as to fix the adjusting clamp 8.

[0045] In the above scheme, the temperature sensing device 9 adopts a thyristor voltage regulator and thermostat, and an elastic clip 91 is connected to the left side of the temperature sensing device 9, and the elastic clip 91 is clamped on the adjustment plate 84. A snap-on drip hose heating hole 92 is penetrated on the right side of the temperature sensing device 9, and a display 93, an indicator light, an emergency button 94 and other sensor indication alarm devices are arranged on the front end face of the temperature sensing device 9.

[0046] As an optimized technical solution of the present invention, the temperature sensing device 9 is clamped on the adjustment plate 84 by an elastic clamp 91. Its position can be changed as the adjustment plate 84 slides, and its fixed position can also be changed by changing the position of the elastic clamp 91. The drip hose 11 will be clamped in the snap-on drip hose heating hole 92 to achieve the heating function of the nutrient solution therein. The temperature sensing device 9 adopts a thyristor voltage regulator and thermostat, which can accurately adjust the temperature of the heater to ensure that the nutrient solution is supplied within an appropriate temperature range to avoid overheating or overcooling causing harm to the patient; it is equipped with a temperature sensor and an alarm system. When the temperature deviates from the set range, it can automatically trigger an alarm to remind medical staff to make timely adjustments to ensure patient safety.

[0047] like Fig. 20 , Fig.21 As shown, the temperature sensing device 9 uses 220V AC voltage, which is stepped down by capacitor C1, rectified by variable capacitance diode VD, filtered by capacitor C2 and stabilized by voltage sensor VS. One path is used as the input DC voltage of integrated circuit IC (TL431 three-terminal voltage regulator integrated circuit); the other path is divided by variable resistor RT, resistor R3 and potentiometer RP to provide control voltage for IC. When the measured temperature is lower than the set temperature of RP, the resistance value of NTC502 negative temperature coefficient thermistor Rr is large, and the control voltage of IC is higher than its turn-on voltage. IC is turned on, LED lights up, VS is triggered and turned on, and electric heater EH is powered on to start heating. As the temperature continues to rise, the resistance value of Rr gradually decreases, and the control voltage of IC also decreases. When the measured temperature is higher than the set temperature, IC is cut off, LED turns off, VS is turned off, EH is powered off and stops heating. Then the temperature begins to drop slowly again. When the measured temperature is lower than the set temperature, IC is turned on again, and EH starts to be powered on and heated again. This cycle continues, and the measured temperature is controlled within the set range.

[0048] Specific implementation cases: When the feeding drip device is used to assist the patient in eating, a disposable gastric tube can be connected to the drip pipe 42, and the medical staff inserts the disposable gastric tube into the patient's stomach to provide the patient's stomach with the nutrient solution required for nutrition, and the upper braces 3 and the lower braces 4 are buckled on the patient's upper and lower teeth, and the jaw support 2 is placed in the patient's lower jaw position, and the ear ring 21 is hung on the patient's ear to achieve effective fixation of the upper braces 3, the lower braces 4 and the jaw support 2.

[0049] Secondly, fix the nutrient solution bottle 1 on the fixed bracket, and clamp the temperature sensing device 9 on the fixed bracket by adjusting the electric clamp 85 on the left end face of the clamp 8, and then connect the drip hose 11 to the nutrient solution bottle 1, so that the drip hose 11 is clamped in the snap-on drip hose heating hole 92 of the temperature sensing device 9, and the circuit control is used to heat the nutrient solution in the drip hose 11, and the temperature sensing device 9 is effectively controlled to continuously heat the drip hose 11, ensuring that the nutrient solution is supplied to the patient within an appropriate temperature range.

[0050] The positional relationship between the upper braces 3, the lower braces 4 and the jaw support 2 can then be adjusted through the adjusting tube 51. During the adjustment process, in order to maintain and support the opening of the patient's mouth, the adjusting tube 51 can be rotated forward. Under the rotation of the adjusting tube 51, the threaded connection relationship between the connecting cap 74 and the external thread 511 is utilized to make the connecting cap 74 move backward on the adjusting tube 51. Driven by the first connecting rod 71, the second connecting rod 72 and the third connecting rod 73, the angle of the jaw support 2 and the tongue depressor 41 can be changed. At the same time, the adjusting tube 51 will also drive the outer spiral sleeve 53 to rotate, and then drive the first gear 56 meshing therewith to rotate. The first gear 56 drives the rotating shaft 54 ​​to rotate, and then drives the outer spiral column 55 to rotate. Due to the meshing relationship between the outer spiral column 55 and the rack 521 on the inner side of the support column 52, the support rod 52 can push the lower braces 4 away from the upper braces 3, so that the upper braces 3 and the lower braces 4 are separated, so as to provide effective support for the patient's open mouth.

[0051] Next, the front end of the drip hose 11 is connected to the infusion pipe 31. In order to prevent the patient's mouth from being in an open state for a long time, the adjusting tube 51 can be rotated in the opposite direction, and then the first gear 56 can be driven to rotate through the outer spiral sleeve 53, so that the outer spiral column 55 can rotate accordingly under the drive of the rotating shaft 54, and then the meshing relationship between the outer spiral column 55 and the rack 521 can be utilized to move the support rod 52 upward, and then the lower braces 4 can be pulled closer to the upper braces 3, so that the upper braces 3 and the lower braces 4 are closed. At the same time, a first accommodating groove 44 and a second accommodating groove 45 are provided on the top of the lower braces 4, so that the connecting component 7 and the infusion pipe 31 can be hidden in the first accommodating groove 44 and the second accommodating groove 45 when the upper braces 3 and the lower braces 4 are closed, so that the movement of the connecting component 7 is affected, and it is also convenient to avoid the infusion pipe 31 being squeezed and bitten to affect the delivery of the nutrient solution.

[0052] At the same time, with the reverse rotation of the adjusting tube 51, the connecting cap 74 can utilize the threaded connection relationship with the external thread 511 to move forward along the adjusting tube 51, and then utilize the second connecting rod 72 to respectively drive the front side of the jaw support 2 to lift up through the first connecting rod 71 and the third connecting rod 73, and press the free end of the tongue depressor 41 downward, so as to prevent the hose for dripping the nutrient solution from being squeezed in the patient's mouth and affecting the eating process.

[0053] Finally, a negative pressure sputum suction device can be connected to the front end of the regulating tube 51 so that the sputum produced in the patient's mouth can be sucked out through the regulating tube 51 during the eating process to avoid affecting the patient's eating process.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
