Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a sucking type Chinese medicine feeding device. Background Art

[0002] Drugs that are collected, processed, and prepared under the guidance of traditional Chinese medical theories, explain their mechanisms of action, and guide their clinical applications are collectively referred to as Chinese medicine. Since Chinese medicine is mostly herbal, there is a saying that "all medicines are based on herbs." Chinese medicine mainly comes from natural medicines and their processed products, including herbal medicines, animal medicines, mineral medicines, and some chemical and biological drugs.

[0003] Due to the materials used, most Chinese medicines are bitter and difficult to swallow. Most adults cannot drink them directly. For children, it is even more difficult to swallow Chinese medicines. Parents or caregivers need to force the medicines in their mouths. Children often spit out the medicines when they are fed. The medicines cannot achieve a good therapeutic effect. At the same time, children resist violently when they are fed medicines. The workload of parents and caregivers is relatively high, which brings great inconvenience to the parents and caregivers of child patients.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to establish a pressure coefficient equation under sucking action, establish the correlation between flow rate and pressure degree of oral intake layer according to the pressure coefficient equation, output pressure adjustment parameters according to real-time displacement change data, and then control the opening and closing degree of electromagnetic flow valve according to the pressure adjustment parameters, so as to control the real-time flow rate through the electromagnetic flow valve in coordination with the sucking force to avoid choking.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a sucking type Chinese medicine feeding device, comprising a medicine storage bottle, an oral intake layer and a pressure control system, a medicine adding pipeline is provided on the top surface of the medicine storage bottle, a threaded portion is provided on the outer surface of the medicine adding pipeline, a port tube is threadedly connected to the outer surface of the threaded portion, an electromagnetic flow valve is fixedly arranged inside the port tube, a medicine feeding hose is connected to the end surface of the port tube, a hard catheter is connected to the end of the medicine feeding hose, after the medicine storage bottle is washed and dried, Chinese medicine liquid with suitable temperature is poured into the medicine adding pipeline, and then the port tube is threadedly connected to the medicine adding pipeline, the medicine feeding hose and the hard catheter are connected to the medicine storage bottle as a whole to form a medicine feeding channel, the oral intake layer is sleeved on the outer surface of the hard catheter, a pressure sensing mechanism is fixedly arranged between the inner wall of the oral intake layer and the hard catheter, and a tongue root patch is fixedly arranged on the end surface of the hard catheter;

[0007] The pressure sensing mechanism includes an elastic rod and a movable rod. The outer surface of the hard tube is sleeved with a fixed ring. Several of the elastic rods are evenly distributed on the inner wall of the oral intake layer. One end of the elastic rod is connected to the outer surface of the fixed ring. The outer surface of the hard tube is movably sleeved with a movable clamping ring. One end of the movable rod is fixed to the outer surface of the movable clamping ring, and the other end of the movable rod is movably connected to the outer surface of the elastic rod. A displacement sensor is fixed inside the movable clamping ring. The patient performs an autonomous sucking action to isolate the Chinese medicine liquid through the oral intake layer. The opening and closing degree of the electromagnetic flow valve is adjusted with the sucking force, thereby adjusting the flow in the medicine feeding channel. The greater the sucking force, the greater the flow in the medicine feeding channel, which not only ensures the medicine feeding efficiency, but also avoids choking caused by overflow of the medicine liquid. At the same time, the electromagnetic flow valve is a one-way valve, which can effectively prevent the medicine liquid from flowing back and causing the medicine liquid in the medicine storage bottle to be contaminated.

[0008] Furthermore, the oral inclusion layer is a funnel-shaped structure, and the oral inclusion layer and the tongue root patch are both made of medical silicone material. The tongue root patch and the oral inclusion layer are an integrally formed structure. The disinfected oral inclusion layer is inserted into the mouth, and the position is adjusted so that the tongue root patch fits the patient's tongue root. The tongue root is a sensitive area for sensing bitterness. The tongue root is covered by the tongue root patch to prevent the taste buds at the tongue root from sensing the drug solution while it flows out of the hard catheter into the throat, and to prevent it from extending excessively into the throat. At the same time, the oral inclusion layer is made to fit the oral wall as much as possible, and the hard catheter is located in the center of the mouth.

[0009] Furthermore, a battery holder is fixedly provided on the outer surface of the port tube, a battery slot is opened on the inner wall of the battery holder, a rechargeable battery is movably connected to the inner wall of the battery slot, and a waterproof charging port is fixedly provided on the outer surface of the battery holder, and the sensor, electromagnetic flow valve and pressure control system are powered by the rechargeable battery.

[0010] Furthermore, a temperature sensor is fixedly provided on the inner wall of the medicine storage bottle, and the temperature of the traditional Chinese medicine liquid in the medicine storage bottle is detected by the temperature sensor.

[0011] Further, the pressure control system includes a data acquisition unit, a pressure modeling unit, a pressure analysis unit, and a flow control unit;

[0012] The data acquisition unit includes a displacement data acquisition module and a temperature data acquisition module. The displacement data acquisition module is used to acquire the displacement data of the movable clamp along the hard catheter through a displacement sensor and send the displacement data to the pressure analysis unit. The temperature acquisition module is used to acquire the temperature data of the Chinese medicine liquid in the medicine storage bottle through a temperature sensor and send it to the flow control unit.

[0013] The pressure modeling unit obtains the initial displacement data after the device is activated, records the pressure state of the oral cavity when no sucking action is performed, obtains the displacement change data during a sucking action when the user performs a sucking action, establishes a pressure coefficient equation under the sucking action, and sends it to the pressure analysis unit;

[0014] The pressure analysis unit obtains the flow adjustment range of the electromagnetic flow valve, establishes the correlation between the flow and the pressure degree of the oral inclusion layer according to the pressure coefficient equation, and outputs the pressure adjustment parameter to the flow control unit according to the real-time displacement change data;

[0015] The flow control unit includes a temperature switch control module and a flow regulation module. The temperature switch control module controls the switching state of the electromagnetic flow valve according to the temperature data of the traditional Chinese medicine liquid. The flow regulation module controls the opening and closing degree of the electromagnetic flow valve according to the pressure regulation parameters to control the real-time flow rate flowing through the electromagnetic flow valve.

[0016] Furthermore, the specific process of establishing the pressure coefficient equation under the sucking action is as follows:

[0017] S101, obtaining the initial displacement data X0 after the device is activated. Due to the linkage structure between the elastic rod and the movable rod, when the elastic rod is compressed, the elastic rod moves toward the direction close to the hard catheter, and the movable clasp is driven by the movable rod to move horizontally along the hard catheter, that is, the displacement data of the movable clasp is positively correlated with the compression state of the elastic rod. The greater the compression degree of the elastic rod, the greater the displacement data of the movable clasp. The normal pressure data F0 of the oral inclusion layer when the user does not perform a sucking action can be known through the initial displacement data X0: F0=k1·X0, where k1 is a preset proportional coefficient;

[0018] S102, obtaining displacement change data during a sucking action, and obtaining a displacement data set B, where B = {X1, X2, X3, ..., Xn}, and Bn is the maximum displacement data;

[0019] S103. According to the displacement data set B and the relationship between the displacement data and the compression data, a compression coefficient equation f(μ) is established: Wherein i=1, 2, 3, ..., n, the pressure coefficient μ in the pressure coefficient equation is used to reflect the pressure change amplitude under the current sucking action. The larger the pressure coefficient μ, the greater the pressure change amplitude under the current sucking action. Conversely, the smaller the pressure coefficient μ, the smaller the pressure change amplitude under the current sucking action. The pressure change under the sucking action is predicted based on the pressure coefficient μ and the real-time displacement change data.

[0020] Furthermore, the specific process of outputting the pressure adjustment parameters according to the real-time displacement change data is as follows:

[0021] S201, obtaining the flow adjustment range (Qmin, Qmax) of the electromagnetic flow valve. According to the fact that the greater the sucking force under the sucking action, the greater the subsequent oral expansion, it can be known that the flow of the electromagnetic flow valve is proportional to the pressure of the oral intake layer, that is, Q = k2·k1·Xt, k2 is a preset proportional coefficient, and Xt is real-time displacement change data;

[0022] S202, obtaining the correlation between the adjustment parameter of the electromagnetic flow valve and the flow rate, it can be known that Q=I·k3, K3 is a preset proportional coefficient, and I is the rated current flowing through the electromagnetic flow valve;

[0023] S203. According to the formula, the adjustment parameter I of the electromagnetic flow valve can be obtained: Substituting the real-time displacement change data into the formula, the output is I, which is the pressure adjustment parameter.

[0024] Furthermore, the specific working process of the temperature switch control module is as follows:

[0025] Obtain the initial temperature of the Chinese medicine liquid detected by the temperature sensor, and preset the inlet temperature range (Tmin, Tmax);

[0026] If the initial temperature of the Chinese medicine liquid is greater than Tmax or less than Tmin, a solenoid flow valve closing signal is generated to control the solenoid flow valve to close;

[0027] If the initial temperature of the traditional Chinese medicine liquid is less than or equal to Tmax and greater than or equal to Tmax, an electromagnetic flow valve opening signal is generated to control the electromagnetic flow valve to open.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The pressure-controlled autonomous sucking Chinese medicine feeding device is provided with a tongue root patch, which covers the tongue root to prevent the taste buds at the tongue root from sensing the medicine liquid when it flows out of the hard catheter into the throat, and to prevent it from excessively extending into the throat. At the same time, the oral intake layer is made to fit the oral wall as much as possible, isolating the Chinese medicine liquid from the taste buds in the oral cavity, so that the patient cannot sense the bitter taste of the Chinese medicine liquid, thus avoiding the discomfort caused by taking the Chinese medicine liquid, reducing the patient's resistance to taking the medicine, and facilitating recovery from the disease.

[0030] 2. The autonomous sucking Chinese medicine feeding device based on pressure control controls the electromagnetic flow valve to make the feeding channel conductive. At this time, the patient performs autonomous sucking movements, and adjusts the opening and closing degree of the electromagnetic flow valve according to the sucking strength, thereby adjusting the flow in the feeding channel. The greater the sucking strength, the greater the flow in the feeding channel, which not only ensures the feeding efficiency, but also avoids choking and coughing caused by excessive sucking strength during the medication process, resulting in excessive overflow of the medicine output. At the same time, the electromagnetic flow valve is a one-way valve, which can effectively prevent the backflow of the medicine and cause the contamination of the medicine in the medicine storage bottle.

[0031] 3. The pressure-controlled autonomous sucking Chinese medicine feeding device can take the medicine into the oral cavity and take it out of the oral cavity after the medicine feeding is completed, and separate the port tube from the medicine storage bottle, clean and disinfect them respectively and then dry them, and then it can be reused. It is suitable for multiple medicine feeding, has low use cost, and is suitable for home use.

[0032] 4. The autonomous sucking Chinese medicine feeding device based on pressure control senses the degree of pressure applied to the oral intake layer by the patient's sucking action through a pressure sensing mechanism. When the user sucks, the displacement change data of the sucking action is obtained, and the pressure coefficient equation under the sucking action is established. The pressure adjustment parameters are output according to the real-time displacement change data, and then the opening and closing degree of the electromagnetic flow valve is controlled according to the pressure adjustment parameters, so as to control the real-time flow rate flowing through the electromagnetic flow valve to solve the choking problem that may occur during the medication process.

[0033] 5. The pressure-controlled autonomous sucking Chinese medicine feeding device is also provided with a temperature sensor, which obtains the temperature data of the Chinese medicine liquid in the medicine storage bottle through the temperature sensor, and controls the switch state of the electromagnetic flow valve according to the temperature data of the Chinese medicine liquid, so as to avoid accidental inhalation of the Chinese medicine liquid when the temperature is too high and cause oral burns, and also avoid taking the Chinese medicine liquid when the temperature is too low and affect the medicinal properties.

The opening and closing degree of the electromagnetic flow valve 4 is adjusted according to the sucking force, and then the flow in the medicine feeding channel is adjusted. The greater the sucking force, the greater the flow in the medicine feeding channel, which not only ensures the medicine feeding efficiency, but also avoids choking caused by overflow of the medicine liquid. At the same time, the electromagnetic flow valve 4 is a one-way valve, which can effectively prevent the medicine liquid from flowing back, causing the medicine liquid in the medicine storage bottle 1 to be contaminated.

[0044] The oral inclusion layer 7 is a funnel-shaped structure. The oral inclusion layer 7 and the tongue root patch 8 are both made of medical silicone material. The tongue root patch 8 and the oral inclusion layer 7 are an integrally formed structure. The disinfected oral inclusion layer 7 is inserted into the mouth, and the position is adjusted so that the tongue root patch 8 fits the patient's tongue root. The tongue root is a sensitive area for sensing bitterness. The tongue root patch 8 covers the tongue root to prevent the taste buds at the tongue root from sensing the drug solution when it flows out of the hard catheter 6 to the throat, and to prevent it from extending excessively into the throat. At the same time, the oral inclusion layer 7 is fitted with the oral wall as much as possible, and the hard catheter 6 is located in the center of the mouth.

[0046] A temperature sensor 17 is fixedly provided on the inner wall of the medicine storage bottle 1 , and the temperature of the Chinese medicine liquid in the medicine storage bottle 1 is detected by the temperature sensor 17 .

[0047] The working principle is as follows: before use, wash and dry the medicine storage bottle 1, pour the Chinese medicine liquid with suitable temperature from the medicine adding pipe 2, then connect the port pipe 3 with the medicine adding pipe 2 by thread, connect the medicine feeding hose 5 and the hard conduit 6 with the medicine storage bottle 1 as a whole, and form a medicine feeding channel;

[0048] When in use, the disinfected oral inclusion layer 7 is inserted into the mouth, and the position is adjusted so that the tongue root patch 8 fits with the tongue root of the patient. The tongue root is a sensitive part that perceives bitterness. The tongue root is covered by the tongue root patch 8 to prevent the taste buds at the tongue root from sensing the drug solution when it flows out of the hard catheter 6 to the throat, and to prevent it from excessively extending into the throat. At the same time, the oral inclusion layer 7 is made to fit with the oral wall as much as possible, and the hard catheter 6 is located in the center of the oral cavity.

[0049] At this time, the electromagnetic flow valve 4 is opened to make the medicine feeding channel conductive. At this time, the patient performs a sucking action autonomously, and the Chinese medicine liquid is isolated by the oral layer 7. The opening and closing degree of the electromagnetic flow valve 4 is adjusted according to the sucking strength, and then the flow in the medicine feeding channel is adjusted. The greater the sucking strength, the greater the flow in the medicine feeding channel, which not only ensures the medicine feeding efficiency, but also avoids the overflow of the medicine liquid and choking. At the same time, the electromagnetic flow valve 4 is a one-way valve, which can effectively prevent the medicine liquid from flowing back, causing the medicine liquid in the medicine storage bottle 1 to be contaminated;

[0050] After the medicine feeding is completed, the oral receiving layer 7 is taken out from the oral cavity, and the port tube 3 is separated from the medicine storage bottle 1, and they are cleaned, disinfected and dried respectively, and can be reused.

[0051] Embodiment 2:

[0052] like Figure 5 As shown, a sucking type Chinese medicine feeding device includes a medicine storage bottle 1, an oral receiving layer 7 and a pressure control system, and the pressure control system includes a data acquisition unit, a pressure modeling unit, a pressure analysis unit, and a flow control unit;

[0053] The data acquisition unit includes a displacement data acquisition module and a temperature data acquisition module. The displacement data acquisition module is used to acquire the displacement data of the movable clamp ring 11 along the hard catheter 6 through the displacement sensor 13, and send the displacement data to the pressure analysis unit. The temperature acquisition module is used to acquire the temperature data of the Chinese medicine liquid in the medicine storage bottle 1 through the temperature sensor 17 and send it to the flow control unit;

[0054] The pressure modeling unit obtains the initial displacement data after the device is activated, records the pressure state of the oral cavity when no sucking action is performed, obtains the displacement change data during a sucking action when the user performs a sucking action, establishes a pressure coefficient equation under the sucking action, and sends it to the pressure analysis unit;

[0055] The specific process of establishing the pressure coefficient equation under the sucking action is as follows:

[0056] S101, obtaining the initial displacement data X0 after the device is activated. Due to the linkage structure between the elastic rod 10 and the movable rod 12, when the elastic rod 10 is compressed, the elastic rod 10 moves toward the direction close to the hard tube 6, and the movable clasp 11 is driven by the movable rod 12 to move horizontally along the hard tube 6, that is, the displacement data of the movable clasp 11 is positively correlated with the compressed state of the elastic rod 10. The greater the compression degree of the elastic rod 10, the greater the displacement data of the movable clasp 11. The normal pressure data F0 of the oral inclusion layer 7 when the user does not perform a sucking action can be known through the initial displacement data X0: F0=k1·X0, k1 is a preset proportional coefficient;

[0057] S102, obtaining displacement change data during a sucking action, and obtaining a displacement data set B, where B = {X1, X2, X3, ..., Xn}, and Bn is the maximum displacement data;

[0058] S103. According to the displacement data set B and the relationship between the displacement data and the compression data, a compression coefficient equation f(μ) is established: Wherein i=1, 2, 3, ..., n, the pressure coefficient μ in the pressure coefficient equation is used to reflect the pressure change amplitude under the current sucking action. The larger the pressure coefficient μ, the greater the pressure change amplitude under the current sucking action. Conversely, the smaller the pressure coefficient μ, the smaller the pressure change amplitude under the current sucking action. The pressure change under the sucking action is predicted based on the pressure coefficient μ and the real-time displacement change data.

[0059] The pressure analysis unit obtains the flow adjustment range of the electromagnetic flow valve 4, establishes the correlation between the flow and the pressure degree of the oral inclusion layer 7 according to the pressure coefficient equation, and outputs the pressure adjustment parameter to the flow control unit according to the real-time displacement change data;

[0060] The specific process of outputting pressure adjustment parameters according to real-time displacement change data is as follows:

[0061] S201, obtaining the flow adjustment range (Qmin, Qmax) of the electromagnetic flow valve 4. According to the fact that the greater the sucking force under the sucking action, the greater the subsequent oral expansion, it can be known that the flow rate of the electromagnetic flow valve 4 is proportional to the pressure degree of the oral inclusion layer 7, that is, Q = k2·k1·Xt, k2 is a preset proportional coefficient, and Xt is real-time displacement change data;

[0062] S202, obtaining the correlation between the adjustment parameter of the electromagnetic flow valve 4 and the flow rate, it can be known that Q=I·k3, K3 is a preset proportionality coefficient, and I is the rated current flowing through the electromagnetic flow valve 4;

[0063] S203, according to the formula conversion, the adjustment parameter I of the electromagnetic flow valve 4 can be obtained: Substituting the real-time displacement change data into the formula, the output is I, which is the pressure adjustment parameter.

[0064] The flow control unit includes a temperature switch control module and a flow regulating module. The temperature switch control module controls the switch state of the electromagnetic flow valve 4 according to the temperature data of the traditional Chinese medicine liquid. The flow regulating module controls the opening and closing degree of the electromagnetic flow valve 4 according to the pressure regulation parameter to control the real-time flow rate flowing through the electromagnetic flow valve 4.

[0065] The specific working process of the temperature switch control module is as follows:

[0066] Obtain the initial temperature of the Chinese medicine liquid detected by the temperature sensor 17, and preset the inlet temperature range (Tmin, Tmax);

[0067] If the initial temperature of the Chinese medicine liquid is greater than Tmax or less than Tmin, a closing signal of the electromagnetic flow valve 4 is generated to control the electromagnetic flow valve 4 to close;

[0068] If the initial temperature of the traditional Chinese medicine liquid is less than or equal to Tmax and greater than or equal to Tmax, an opening signal of the electromagnetic flow valve 4 is generated to control the electromagnetic flow valve 4 to open.

[0069] The present invention obtains displacement data of the movable clamp 11 along the hard catheter 6 through the displacement sensor 13. When the user performs a sucking action, the displacement change data during one sucking action is obtained, and a pressure coefficient equation under the sucking action is established and sent to the pressure analysis unit. According to the pressure coefficient equation, a correlation between the flow rate and the pressure degree of the oral inclusion layer 7 is established, and a pressure adjustment parameter is output according to the real-time displacement change data, and then the opening and closing degree of the electromagnetic flow valve 4 is controlled according to the pressure adjustment parameter to control the real-time flow rate flowing through the electromagnetic flow valve 4;

[0070] A temperature sensor 17 is also provided, through which the temperature data of the Chinese medicine liquid in the medicine storage bottle 1 is obtained, and the switch state of the electromagnetic flow valve 4 is controlled according to the temperature data of the Chinese medicine liquid, so as to avoid accidental inhalation of the Chinese medicine liquid when the temperature is too high and cause oral burns, and also to avoid taking the Chinese medicine liquid when the temperature is too low and affect the medicinal properties.

[0071] The size of the interval is set to facilitate comparison. The size of the interval value depends on the amount of sample data and the number of bases set by technical personnel in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0072] The above formulas are all dimensionless and numerical calculations. The formula is a formula that is closest to the actual situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions;

A sucking type Chinese medicine feeding device according to claim 5, characterized in that: The specific process of establishing the pressure coefficient equation under the sucking action is as follows: S101, obtaining the initial displacement data X0 after the device is activated. Due to the linkage structure between the elastic rod (10) and the movable rod (12), when the elastic rod (10) is compressed, the elastic rod (10) moves toward the direction close to the hard catheter (6), and drives the movable clasp (11) to move horizontally along the hard catheter (6) through the movable rod (12), that is, the displacement data of the movable clasp (11) is positively correlated with the compressed state of the elastic rod (10). The greater the compression degree of the elastic rod (10), the greater the displacement data of the movable clasp (11). The normal pressure data F0 of the oral receiving layer (7) when the user does not perform a sucking action can be known through the initial displacement data X0: F0=k1·X0, where k1 is a preset proportionality coefficient; S102, obtaining displacement change data during a sucking action, and obtaining a displacement data set B, where B = {X1, X2, X3, ..., Xn}, and Bn is the maximum displacement data; S103. According to the displacement data set B and the relationship between the displacement data and the compression data, a compression coefficient equation f(μ) is established: Wherein i=1, 2, 3, ..., n, the pressure coefficient μ in the pressure coefficient equation is used to reflect the pressure change amplitude under the current sucking action. The larger the pressure coefficient μ, the greater the pressure change amplitude under the current sucking action. Conversely, the smaller the pressure coefficient μ, the smaller the pressure change amplitude under the current sucking action. The pressure change under the sucking action is predicted based on the pressure coefficient μ and the real-time displacement change data.

According to the fact that the greater the sucking force during the sucking action, the greater the subsequent oral cavity expansion, it can be known that the flow rate of the electromagnetic flow valve (4) is proportional to the pressure level of the oral cavity receiving layer (7), that is, Q = k2·k1·Xt, k2 is a preset proportionality coefficient, and Xt is real-time displacement change data; S202, obtaining the correlation between the adjustment parameter of the electromagnetic flow valve (4) and the flow rate, it can be known that Q=I·k3, K3 is a preset proportionality coefficient, and I is a rated current flowing through the electromagnetic flow valve (4); S203. According to the formula, the adjustment parameter I of the electromagnetic flow valve (4) can be obtained: Substituting the real-time displacement change data into the formula, the output is I, which is the pressure adjustment parameter.
