Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to a constant temperature nasogastric feeding device and a use method thereof. Background Art

[0002] For patients who cannot eat orally, nasogastric feeding is an important means of nutritional support. The nutrient solution is easily affected by the external environment temperature during the delivery process, especially in cold seasons or air-conditioned environments. The temperature of the nutrient solution will drop rapidly. At the same time, when warm boiled water is injected, the boiled water needs to be cooled to a suitable temperature before injection, which affects the delivery of the nutrient solution. When the nasogastric feeding tube is connected to different push liquids, the nasogastric feeding tube needs to be connected to different push liquids. Medical staff not only need to disinfect the nasogastric feeding tube connector multiple times, but also when the nasogastric feeding tube is separated from the nutrient solution container, the residual nutrient solution in the tube is likely to leak and needs to be cleaned again. At the same time, when the nasogastric feeding tube is not firmly fixed to the nose, it is easy to slide outward, and it is difficult to judge after the nasogastric feeding tube slides outward. When the patient has adverse reactions, adjustments are made, which is not conducive to nasogastric feeding for the patient.

[0003] To this end, we propose a constant temperature nasogastric feeding device and a method of use. Summary of the invention

[0004] The main purpose of the present invention is to provide a constant temperature nasogastric feeding device and a method of use.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

The connecting hole is connected to one end of the nasogastric tube body through a pipe joint. The outer wall of the nasogastric tube body is snap-connected with two front arc plates and a rear arc plate. The outer walls of the two front arc plates and the two rear arc plates are respectively installed with corresponding monitoring rings, and a pressure sensing module is installed on one side of one of the monitoring rings. The nasogastric tube body passes through the peristaltic pump, and the pressure sensing module and the peristaltic pump are connected by the signal of the PLC control unit.

[0007] A further improvement of the present invention is that a clamping plate for limiting the position of the warm water tank and the bag storage rack is installed on the inner wall of the constant temperature shell, the heating control unit is sealed and connected to the top of the constant temperature shell, and the heating rod is located outside the warm water tank and the bag storage rack.

[0008] A further improvement of the present invention is that the nasogastric tube body passes through the infusion warmer, and the temperature detection module is connected to the heating control unit and the infusion warmer through the PLC control unit signal.

[0009] A further improvement of the present invention is that the outer walls of the front arc plate and the rear arc plate are both provided with restraint grooves, wherein two inner walls of the restraint grooves are fixedly connected with restraint belts, and the two restraint belts are respectively wrapped around the outer walls of the front arc plate and the rear arc plate, wherein the outer walls of the two monitoring rings on the rear arc plate are installed with hanging ropes for hanging on the patient's ears.

[0010] A further improvement of the present invention is that the outer wall of the adjustment rotating plate is fixedly connected to two corresponding docking blocks, a docking plate corresponding to the docking block is installed at the bottom end of the base, a limiting slot is slidably connected to the docking plate, a spring is provided on the outer wall of the limiting slot, and one end of the limiting slot is engaged with one side of the docking block.

[0011] A further improvement of the present invention is a constant temperature nasogastric feeding device and a method of use, comprising:

[0012] S1. When in use, the nutrition bag is installed in the bag storage rack, a certain amount of water that can wrap the nutrition bag is stored in the constant temperature shell, and a certain amount of warm boiled water is stored separately in the warm water tank. The water in the constant temperature shell can be heated by the heating control unit and the heating rod, so that the nutrition bag and the warm water tank are in a certain temperature environment to prevent their temperature from dropping, so that the nutrient solution in the nutrition bag can be heated by the water in the constant temperature shell before injection. When performing nasogastric feeding of nutrient solution, the connecting hole provided on the adjusting rotating plate rotatably connected to the sealing circular plate corresponds to a connecting pipe connected to the nutrition bag, so that the nutrient solution in the nutrition bag can flow into the nasogastric feeding tube body through the connecting pipe, the drainage control and the connecting hole. After being connected to the peristaltic pump, the nasogastric feeding tube body can be powered by the peristaltic pump and accurately control the infusion speed and time of the nutrient solution. Then, the nutrient solution flowing in the nasogastric feeding tube body is heated by the infusion heater, so that the injected nutrient solution can be heated to a certain temperature to prevent the nutrient solution with too low temperature from entering the patient's stomach and possibly irritating the gastrointestinal tract;

[0013] S2. Detect the temperature of the nutrient solution after it is heated and separated from the infusion heater through the temperature detection module. When the temperature is lower than the set threshold, the PLC control unit can transmit a signal to control the peristaltic pump to slow down its injection speed of the nutrient solution. At the same time, the heating control unit can be coordinated with the heating rod to heat the insulation liquid in the constant temperature shell to increase the temperature of the nutrient solution in the nutrient bag, so that it is convenient to transport the nutrient solution. The heating control unit, the heating rod, the peristaltic pump and the infusion heater are coordinated to heat the nutrient solution injected into the patient's tail to an appropriate temperature.

[0014] S3. After the nasofeeding tube body is moved outwards, causing the position of one end of the nasofeeding tube body to change, the rear arc plate can be fixed in position under the traction and fixation of the monitoring ring and the hanging rope hung on the ear, and the front arc plate engaged with the outer wall of the nasofeeding tube body will move outwards synchronously with the nasofeeding tube body, and support the pressure sensing module installed on one side of the monitoring ring installed on the rear arc plate, so that after the pressure sensing module is subjected to pressure, it can cooperate with the PLC control unit to control the peristaltic pump to stop the delivery of nutrient solution, thereby facilitating timely push injection control after the nasofeeding tube body moves outwards, and facilitating medical staff to judge whether the nasofeeding tube body has moved outwards through the distance between the front arc plate and the rear arc plate, thereby protecting the patient during nasofeeding.

[0015] Compared with the prior art, the temperature of the nutrient bag in the constant temperature shell and the water in the warm water tank can be maintained under the heating of the heating control unit and the heating rod to avoid low temperature. At the same time, the temperature of the warm boiled water can be controlled in advance, so that when the nutrient solution is blocked, the connecting hole opened on the adjusting plate can be directly adjusted to correspond to another drainage control, avoiding the need for multiple disinfections when the nasogastric feeding tube body is plugged in and out, and causing part of the nutrient solution to leak out when plugging in and out.

[0016] Compared with the prior art, the front arc plate is synchronized with the position of the nasofeeding tube body, and the rear arc plate is synchronized with the position of the patient's face, so that after the nasofeeding tube body moves outward, the monitoring ring on the front arc plate can be supported on the pressure sensing module, so that after the pressure sensing module is subjected to pressure, it cooperates with the PLC control unit to control the peristaltic pump to stop the delivery of nutrient solution, and it is convenient for medical staff to judge whether the nasofeeding tube body has moved outward through the distance between the front arc plate and the rear arc plate, thereby protecting the patient when performing nasofeeding.

A connecting hole 331 corresponding to the liquid discharge control 33 is opened on the adjusting rotating plate 31. The connecting hole 331 is connected to one end of the nasogastric tube body 4 through a pipe joint 32. The outer wall of the nasogastric tube body 4 is snap-connected with two front arc plates 41 and a rear arc plate 42. The outer walls of the two front arc plates 41 and the two rear arc plates 42 are all equipped with corresponding monitoring rings 45, and a pressure sensing module 46 is installed on one side of one of the monitoring rings 45. The nasogastric tube body 4 passes through the peristaltic pump 5, and the pressure sensing module 46 is connected to the peristaltic pump 5 through the signal of the PLC control unit 51.

[0029] In this embodiment, when the thermostatic shell 1 is in use, it is installed with the base 11 through its bottom. Before being installed to the bottom of the thermostatic shell 1, the base 11 can be connected to the drainage control 33 opened at the bottom of the thermostatic shell 1 through the nutrient bag 14. After the nutrient bag 14 is installed, the nutrient bag 14 can be limited by the bag storage rack 13 supported in the base 11, so that the nutrient bag 14 can be limited by the bag storage rack 13 and be vertically located in the thermostatic shell 1. At the same time, the warm water tank 12 is on one side of the nutrient bag 14, and it and the nutrient bag 14 are in the inner cavity of the thermostatic shell 1 at the same time. The warm water tank 12 is also connected to another drainage control 33 through the connecting pipe 141. When in use, the heating control unit 2 is installed at the top position of the thermostatic shell 1. The several heating rods 21 installed on the heating control unit 2 are inserted into the inner cavity of the constant temperature shell 1, and the constant temperature shell 1 is filled with clean water so that it can be heated by the heating control unit 2 and the heating rods 21 to maintain a certain temperature, so that the nutrient bag 14 in the constant temperature shell 1 and the warm boiled water reserved in the warm water tank 12 can be kept warm by the clean water heated in the constant temperature shell 1 without causing the temperature to drop, so that the nutrient solution in the nutrient bag 14 can be heated by the water in the constant temperature shell 1 before injection, and when the nutrient solution is nasogastricly fed, the connecting hole 331 on the adjusting rotating plate 31 rotatably connected to the sealing circular plate 3 corresponds to a connecting pipe 141 connected to the nutrient bag 14, so that the nutrient solution in the nutrient bag 14 can pass through The connecting tube 141, the drainage control 33 and the connecting hole 331 flow into the nasogastric tube body 4.

The nasogastric tube body 4 passes through the peristaltic pump 5. Under the action of the peristaltic pump 5, the nasogastric tube body 4 can be connected with the peristaltic pump 5 to provide power and accurately control the injection speed and time of the nutrient solution.

The nutrient solution is heated. When the injection speed is fast and it is not convenient to heat the nutrient solution to the required temperature, the temperature detection module 61 can detect the temperature of the nutrient solution after it is heated and separated from the infusion heater 6. When the temperature is lower than the set threshold, a signal can be transmitted to the PLC control unit 51, so that the PLC control unit 51 can control the peristaltic pump 5 to slow down its injection speed of the nutrient solution. At the same time, the heating control unit 2 can cooperate with the heating rod 21 to heat the insulation liquid in the constant temperature shell 1, thereby increasing the temperature of the nutrient solution in the nutrient bag 14 and making it easier to transport the nutrient solution. The heating control unit 2, the heating rod 21, the peristaltic pump 5 and the infusion heater 6 can be used to heat the nutrient solution injected into the patient's tail to an appropriate temperature.When the peristaltic pump 5 continuously pushes the nutrient solution, when the nasogastric feeding tube body 4 moves outward, the position of one end of the nasogastric feeding tube body 4 at the tail is changed.

After the nasogastric tube body (4) is moved outwards, causing the position of one end of the nasogastric tube body (4) to change, the rear arc plate (42) can be fixed in position under the traction and fixation of the monitoring ring (45) and the hanging rope (47) hung on the ear, and the front arc plate (41) engaged with the outer wall of the nasogastric tube body (4) will move outwards synchronously with the nasogastric tube body (4) and support the pressure sensing module (46) installed on one side of the monitoring ring (45) installed on the rear arc plate (42), so that after the pressure sensing module (46) is subjected to pressure, it can cooperate with the PLC control unit (51) to control the peristaltic pump (5) to stop the nutrient solution delivery, thereby facilitating timely injection control after the nasogastric tube body (4) moves outwards, and facilitating medical staff to judge whether the nasogastric tube body (4) moves outwards through the distance between the front arc plate (41) and the rear arc plate (42), so that the patient can be protected when the nasogastric tube body (4) is undergoing nasogastric feeding.
