Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and in particular to a feeding device for artificial intelligence radiotherapy nursing. Background Art

[0002] The principle of radiotherapy is to use high-energy ionizing radiation to directly damage the DNA structure of cancer cells, thereby preventing their growth and division, achieving the therapeutic effect. This treatment method can inhibit a variety of malignant tumors and can also preserve organ function to achieve the effect of curing diseases. As one of the important means for the treatment of malignant tumors, radiotherapy can effectively kill tumor cells, but it will also cause certain damage to normal cells, thus triggering a series of side effects. First, the skin in the radiotherapy area may appear red, peeling, blackening or darkening, and in severe cases, there may even be phenomena such as exudation and erosion. Second, the oral mucosa, nasal mucosa, esophageal mucosa, etc. may be damaged, showing symptoms such as pain, ulcers, and bleeding. Third, radiotherapy may cause digestive tract symptoms such as nausea, vomiting, loss of appetite, constipation, and diarrhea. Fourth, systemic reactions, and patients often feel weak and listless. When a certain side effect causes greater damage to the human body, doctors will use corresponding drugs to relieve the side effects of the human body. During the process of fighting against tumors, some patients may not be able to eat and take medicine normally in the later stage. Clinically, in order to ensure the nutritional supply and drug supply for patients, the method of nasal feeding is often used to achieve eating and feeding medicine.

[0003] However, the existing process of nasal feeding drugs is as follows. First, for liquid drugs, usually a syringe is directly used to aspirate, and then the drug is directly pushed into the nasal feeding tube through the syringe. Second, for solid drugs, the solid drugs are usually crushed and then melted with a solvent, and then aspirated with a syringe and pushed into the nasal feeding tube.

[0004] As can be seen from the above, during the existing process of nasal feeding solid drugs, the drugs need to be crushed and then melted with a solvent. However, the existing solid drugs cannot be directly crushed in a syringe. Therefore, there will inevitably be losses during the process of crushing, melting, and transferring the solid drugs to the syringe. At the same time, some drugs are not suitable for crushing under aerobic conditions, that is, during the crushing process of the drugs, they will react with oxygen and lose their medicinal properties. Based on the above situation, it is necessary to design a feeding device for artificial intelligence radiotherapy nursing to solve the above problems. Summary of the Invention

[0005] The present invention provides a feeding device for artificial intelligence radiotherapy nursing, which can realize the crushing of solid drugs under negative pressure or in a solvent, and then directly inject them into the nasal feeding tube, reducing the loss of the medicinal properties of solid drugs that are easily oxidized during the crushing process and reducing the loss of the drug amount.

[0006] The technical problems solved by the present invention are realized by adopting the following technical solutions:

[0007] The present invention provides a feeding device for artificial intelligence radiotherapy nursing, including a processing chamber for providing a processing space for pre-treated drugs. The processing chamber can be adjusted between a closed state and an open state, a grinding assembly, which includes a driving member disposed outside the processing space and a grinding member extending into the processing space and driven by the driving member to be able to crush the drugs inside the processing space. It also includes a pneumatic pressure regulating assembly for regulating the internal air pressure of the processing chamber in the closed state. The pneumatic pressure regulating assembly is a gas pump disposed outside the processing chamber. The gas pump is detachably communicated with the processing chamber through a first air flow pipeline, and the gas pump is communicated with the external atmosphere through a second air flow pipeline. A controller, the output end of the controller is used to issue control instructions, and the control instructions are used to control the grinding assembly and the pneumatic pressure regulating assembly to work.

[0008] Preferably, it further includes a pneumatic pressure sensor for monitoring the internal air pressure of the processing chamber. The input end of the controller is connected to the output end of the pneumatic pressure sensor for receiving the air pressure signal sent by the pneumatic pressure sensor.

The output end of the solvent injection pump is internally communicated with the processing chamber through a solvent output pipe. The input end of the solvent injection pump is provided with a solvent suction pipe, and the solvent suction pipe extends into the interior of the container.

[0010] Preferably, the processing chamber has three connection ports, which are respectively a gas connection port, a solvent connection port and a drug discharge port. The gas connection port is detachably connected to the first air flow pipeline, the solvent connection port is detachably connected to the solvent output pipe, and the drug discharge port is closed and opened through a plug cap.

[0015] The beneficial effects of the present invention are as follows: By providing a grinding assembly, the drugs inside the processing chamber can be directly ground. By providing a pneumatic pressure regulating assembly, the drugs inside the processing chamber can be ground under negative pressure conditions, reducing the degree of oxidation of the drugs, protecting the drug efficacy. At the same time, the pneumatic pressure regulating assembly is also used to push the medicament inside the processing chamber into the nasogastric tube, thereby achieving the protection of the drug efficacy as much as possible and reducing the loss of the drug dosage.

[0016] By providing a solvent injection pump, the solid drugs can be crushed when the container is filled with a solvent, thereby reducing the oxidation of the drugs. Moreover, the solid drugs have a better effect of dissolving while being crushed in the solvent, and have a stirring function, reducing the formation of large particles.

Detailed implementation mode

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0027] In order to enable those skilled in the art to know the inventive points of the present invention, in the later stage of existing cancer patients when they are unable to eat and take medicine normally, a nasogastric tube is usually used for the supply of nutrition and medicine. The existing medicine supply device is only a single syringe. The medicament formed by dissolving solid medicine by suction with the syringe is then pushed into the nasogastric tube through the syringe to achieve the drug support for the human body. However, the existing syringe cannot meet the crushing of solid medicine, so there will inevitably be losses (adhering to the inner wall of the crushing device or the inner wall of the dissolving device) during the transfer of the granular medicine to the syringe after being crushed and dissolved externally. Secondly, some granular medicines cannot be crushed and used because they are easily oxidized after being crushed, or they should be used immediately after being crushed. (The solid granular medicines referred to in the present invention have an anti-oxidation layer on the outer surface and a medicinal ingredient inside, and this medicinal ingredient is unstable and easily reacts with oxygen, resulting in a decrease or loss of medicinal properties). In order to solve the difficulties of the existing such medicines during nasogastric feeding, the present invention provides a feeding device for artificial intelligence radiotherapy nursing.

[0028] Reference Figure 1 - Figure 5, an artificial intelligence radiotherapy nursing medicine feeding device provided by the present invention includes a processing chamber for preprocessing drugs. The processing chamber is defined by a housing 3 composed of a first part 302 and a second part 301 that can be threadedly connected. Of course, other detachable connection methods can also be adopted between the first part 302 and the second part 301. When the first part 302 is separated from the second part 301, solid particulate drugs can be placed inside the first part 302 or the second part 301, and then the first part 302 and the second part 301 are connected to form a processing chamber for preprocessing drugs. The medicine feeding device further includes an execution mechanism 1. The execution mechanism 1 includes a grinding assembly, a pneumatic pressure regulating assembly, and a controller 7 (and a solvent injection assembly proposed below). Specifically, a mounting body 101 can be used to carry the pneumatic pressure regulating assembly, the grinding assembly, and the controller 7. The grinding assembly includes a driving member placed outside the processing space and a grinding member extending into the processing space and driven by the driving member to be able to crush the drugs inside the processing space. The driving member preferably adopts a motor 103 fixed on the mounting body 101. The grinding member is an output shaft 5 and a crushing blade 501 at the output end of the motor 103. The output shaft 5 is rotationally sealed through the inside and outside of the processing chamber. The crushing blade 501 is inside the processing chamber. When the motor 103 drives the crushing blade 501 on the output shaft 5 to rotate, the crushing blade 501 grinds and crushes the solid drugs inside the processing chamber. The pneumatic pressure regulating assembly is used to adjust the internal air pressure of the processing chamber in a closed state. Specifically, the pneumatic pressure regulating assembly includes a gas pump 104 fixed on the mounting body 101. The gas pump 104 is detachably communicated with the processing chamber through a first air flow pipe 8. The gas pump 104 is communicated with the external atmosphere through a second air flow pipe 9. An air filter 10 is provided on the second air flow pipe 9. When the gas pump 104 works, it can realize the charging of external atmosphere into the inside of the processing chamber or the discharge of the air inside the processing chamber into the atmosphere, that is, by controlling the pumping or air supply working state of the gas pump 104, the internal air pressure of the processing chamber is adjusted. The controller 7 is mainly used to send control instructions to control the operation of the grinding assembly and the pneumatic pressure regulating assembly. Specifically, the motor 103 of the grinding assembly and the gas pump 104 of the pneumatic pressure regulating assembly are both electrically connected to the controller 7 and are controlled by the controller 7 to operate.

[0029] During specific operation, when it is necessary to grind the solid particulate drugs inside the processing chamber, first ensure that the inside of the processing chamber is in a sealed state. The pneumatic pressure regulating assembly is controlled by the controller 7 to work, so that a negative pressure is generated inside the processing chamber to reduce the air inside the processing chamber. Then, the grinding assembly is controlled by the controller 7 to grind and crush the solid particulate drugs inside the sealed processing chamber, which can avoid the problem of drugs losing their efficacy due to excessive oxidation.

[0030] In order to enable those skilled in the art to clearly understand how the processing chamber defined by the housing 3 above is sealed, the specific structure of the housing 3 will be introduced here. The overall housing 3 is a hollow cylindrical shape composed of a detachable first part 302 and a second part 301. The hollow part is the processing chamber. There are three connection ports on the housing 3 (the three connection ports can be located on either the first part 302 or the second part 301), namely a gas connection port 305, a solvent connection port 304, and a drug discharge port 306. Among them, the gas connection port 305 is detachably connected to the first gas pipeline 8, the solvent connection port 304 is detachably connected to the solvent output pipe 403, and the drug discharge port 306 is in a closed and open state through a plugging cap 12. When the first part 302 and the second part 301 of the housing 3 are stably connected, the solvent connection port 304 is kept in a sealed connection (detachable) with the solvent output pipe 403, and the gas connection port 305 is in a sealed connection (detachable) with the first gas pipeline 8. Then the remaining drug discharge port 306 is plugged by the plugging cap 12, and the sealing of the processing chamber can be achieved. When the plugging cap 12 is removed from the drug discharge port 306, the processing chamber can be in an open state.

[0031] Among them, in order to efficiently crush the solid particle drug during the crushing and grinding process, the space for crushing and grinding should be made smaller. Therefore, a bottom support 6 is provided inside the above-mentioned first part 302. The output shaft 5 at the output end of the motor 103 penetrates through the bottom support 6 and enters the interior of the processing chamber. The crushing blade 501 of the bottom support 6 is in a state of being adjacent to the bottom support 6. A filter screen 303 is provided inside the second part 301. Thus, the solid particle drug is crushed in a smaller space during the crushing and grinding process, and at the same time, the filter screen 303 also facilitates the passage of large particle drugs during the subsequent drug discharge process and avoids blockage.

[0032] The medicine feeding device of the present invention further includes a solvent injection assembly. This solvent injection assembly includes a solvent injection pump 102, a container 2 for containing the solvent, and a solvent pipeline 4. The solvent injection pump 102 can also be installed on the placement body 101. The solvent pipeline 4 is a solvent suction pipe 401 at the input end of the solvent injection pump 102, which can extend into the interior of the container 2 and a solvent output pipe 403 at the output end of the solvent injection pump 102, which is connected to the solvent connection port 304 on the processing chamber. The solvent injection pump 102 is electrically connected to the controller 7. When the controller 7 controls the solvent injection pump 102 to work, the solvent injection pump 102 extracts the solvent inside the container 2 through the solvent suction pipe 401, and then discharges it into the interior of the processing chamber through the solvent output pipe 403 to dissolve the crushed solid particle drug to form a medicament (this medicament may also contain small particles).

[0033] Specifically, when the medicine feeding device of the present invention includes a solvent injection component, its usage process can also be as follows: First, disassemble the first part 302 and the second part 301 of the housing 3, put solid particulate medicine between the first part 302 or the second part 301, then connect the first part 302 and the second part 301 to form a treatment chamber, connect the medicine output pipe, the first air flow pipeline 8 and the plugging cap 12 to seal the treatment chamber, and hold the medicine feeding device in the Figure 6 state, with the medicine discharge port 306 facing upward. The controller 7 controls the air pressure regulating component to make the inside of the treatment chamber in a negative pressure state. After the pressure regulation is completed, the air content inside the treatment chamber is less. At this time, the controller 7 controls the solvent injection pump 102 to work, and fills an appropriate amount of solvent into the treatment chamber. Then, it controls the grinding component to grind and crush the solid particulate medicine inside the treatment chamber. Since the solid particulate medicine is wrapped by the solvent during the grinding process, its degree of oxidation is further reduced, thereby achieving a better effect of maintaining the medicinal effect. When the solid particulate medicine is basically melted or basically forms smaller solid particles and can pass through the filter screen 303, remove the plugging cap 12, connect the medicine discharge port 306 to the nasogastric tube placed in the human body, and then place the medicine feeding device in the Figure 7 state, with the medicine discharge port 306 facing downward. The controller 7 controls the air pressure regulating component to work, inflate the inside of the treatment chamber, and the air pressure inside the treatment chamber gradually increases, pushing the medicine into the nasogastric tube. When the medicine inside the treatment chamber is emptied, temporarily separate the medicine discharge port 306 from the nasogastric tube. Then, the controller 7 controls the solvent injection pump 102 to continue injecting solvent into the treatment chamber to wash the residual medicine components on the inner wall of the treatment chamber. After the solvent fills the treatment chamber, reconnect the medicine discharge port 306 to the nasogastric tube, and control the air pressure regulating component to inflate the inside of the treatment chamber, and the solvent enters the nasogastric tube again. Repeat this process to reduce the waste of medicine.

[0034] It should be further noted that the air pressure regulating component further includes an air pressure sensor 13, which is used to monitor the air pressure inside the treatment chamber. The air pressure sensor 13 can be set on the first air flow pipeline 8. Through the feedback signal of the air pressure sensor 13, the controller 7 can know the current air pressure magnitude inside the treatment chamber. When the air pressure magnitude reaches the set value, the controller 7 controls the gas pump 104 to stop working.

[0035] Furthermore, in order to ensure that the air pressure regulating component is convenient for controlling the air pressure magnitude inside the treatment chamber and to ensure the sealing of the first air flow pipeline 8 and the solvent output pipe 403 during the air pressure regulation process, electromagnetic valves 11 are also provided on the first air flow pipeline 8 and the solvent output pipe 403. The electromagnetic valves 11 are used to control the closing and opening of the pipeline and operate under the control of the controller 7.

[0036] Further, to facilitate personnel in holding the medicine feeding device, the container 2 can be configured into two parts with a holding portion 201 and a storage portion. The end of the holding portion 201 is threadedly and sealedly connected to the placement body 101. The above-mentioned solvent suction pipe 401 is a flexible pipe and extends into the interior of the storage portion. A gravity ball 402 is provided at the end of the solvent suction pipe 401. The first part 302 of the housing 3 is also fixed to the placement body 101, thereby facilitating personnel to perform a single-handed holding operation.

[0037] Further, the controller 7 should have a control main board (not shown in the figure) for receiving instructions and controlling each component to perform corresponding operations according to the instructions. It should also have a human-computer interaction function to facilitate personnel to operate the instructions. Specifically, it can be a button 701, and different components can be controlled by pressing different buttons 701. It can also be a touch display screen 702, and the instructions can be manipulated by touching the display screen. It can also be a combination of both.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
