Description

Detection equipment and use method for positioning human body cavity based on heat stroke principle

Technical Field

The present invention relates to the field of heat stroke treatment equipment, and in particular to a detection device and a use method for locating a human body cavity based on the heat stroke principle.

Background Art

As for heat stroke, its pathogenesis is due to the imbalance of the body's regulatory function when exposed to high temperature and high humidity, and the heat production is greater than the heat dissipation, which leads to a rapid increase in core temperature to over 40°C, accompanied by burning skin, impaired consciousness (such as delirium, convulsions, coma) and multiple organ dysfunction. It is a serious and fatal disease. Before the onset of the disease, most patients are in a relatively hot environment without normal ventilation, which causes the problems in the body to rise rapidly and cannot effectively dissipate heat, leading to the onset of the disease. Because patients will have impaired consciousness such as fainting when they are ill, in many cases it is not possible to rescue the patient in the first time and dissipate heat from their body in time, which causes the patient to lose his life.

Because the main reason for heat stroke patients after the onset of the disease is that the core temperature of the human body is too high, which leads to the failure of various organs. Therefore, it is very important to dissipate heat for patients in time during the rescue operation. At present, most hospitals use external heat dissipation to treat heat stroke patients. Although this method can dissipate heat for the patient's body, it is slow. And for heat stroke patients, the main reason is that their internal core temperature is too high, which causes the problem that the patient's various organs cannot work normally. Therefore, the external heat dissipation effect is also poor. For the patient's internal heat dissipation method, it is necessary to judge the specific temperature of the patient's inner cavity and the location of the main heat source. However, the traditional heat dissipation method is also more difficult for the patient's smaller inner cavity. It is also impossible to effectively dissipate heat for the patient's inner cavity in a short time, thus affecting the patient's rescue timing.

Based on the above problems, it is necessary to design detection equipment and usage methods for locating the human body cavity based on the principle of heat stroke. The type of the patient's internal organs can be judged by the temperature of the patient's internal cavity. At the same time, the patient's internal cavity space can be effectively dissipated to ensure that the patient's internal cavity temperature can be lowered in a short time to increase the patient's chance of survival.

Summary of the invention

The purpose of the present invention is to provide a detection device and a method for using the human body cavity positioning based on the principle of heat stroke. The device determines the type of the patient's internal cavity organs by measuring the temperature of the patient's internal cavity; at the same time, it can effectively dissipate heat from the patient's internal cavity space, thereby ensuring that the patient's internal cavity temperature can be reduced in a short time, thereby increasing the patient's chance of survival after rescue.

In order to achieve the above object, the present invention is implemented through the following technical solutions:

Detection equipment for locating the human body cavity based on the principle of heat stroke, including insertion tube and delivery system;

The conveying system includes a control system and a conveying device. The control system is connected to the conveying device to control the conveying device. The conveying device is a cooling source conveying device, and the cooling source is conveyed to the deep pipe through the conveying device.

The in-depth tube includes a docking tube and a cooling tube. The docking tube is connected to the conveying device. After the cooling tube is connected to the docking tube, it extends into the patient's inner cavity position; the docking tube includes an inlet tube and an outlet tube. The inlet tube and the outlet tube are respectively docked and connected to the inlet end and the outlet end of the output device, and the two ends of the cooling tube are respectively connected to the inner ports of the inlet tube and the outlet tube to form a closed pipeline.

The cooling pipe includes an air outlet pipe and an exchange pipe, and the air outlet pipe and the exchange pipe are connected to the inlet pipe of the docking pipe through a tee; the air outlet pipe is a soft straight pipe, and when the insertion tube is inserted into the patient's digestive tract, the lower port of the air outlet pipe is located above the patient's esophagus; the two ends of the exchange pipe are respectively connected to the inner ports of the inlet pipe and the outlet pipe to form a closed pipeline.

Ejector valve ports are arranged at equal intervals on the exchange tube, and the air in the patient's inner cavity is sucked through the ejector valve ports.

The ejector valve port includes an extrusion end, a diffuser end, and a suction chamber, wherein a suction port is arranged in cooperation with the suction chamber; the diffuser end is communicated with the suction chamber, and the extrusion end is arranged inside the suction chamber and is arranged non-contactly close to the diffuser end.

The extrusion end is a conical nozzle, and the cold source entering the exchange tube flows out from the conical nozzle position when passing through the ejector valve port; the diffusion end is an inverted conical butt-joint tube, and the cold source flowing out from the conical nozzle position is sprayed into the inverted conical butt-joint tube through the suction chamber.

A limit expansion piece is provided at the butt joint position between the butt joint pipe and the cooling pipe, and the oral cavity and throat of the patient are limitedly expanded by the limit expansion piece.

The method for using the detection device for locating the human body cavity based on the principle of heat stroke includes the following steps:

S1, the medical staff lubricates the patient's mouth and throat to determine whether the patient has autonomous consciousness; if the patient has autonomous consciousness, the deep tube is inserted using the normal gastric tube insertion method; if the patient has no autonomous consciousness, the deep tube is inserted using the gastric tube insertion method without autonomous consciousness;

S6, the cold source gas entering the exchange tube passes through the ejector valve body. When the high-pressure cold source gas enters the conical nozzle, as the diameter of the conical nozzle continues to decrease, the pressure energy of the gas is converted into speed energy, i.e., kinetic energy, so that a vacuum is formed in the outlet area of the conical nozzle, and the stomach heat source gas connected to the suction chamber is sucked out of the suction port provided on the suction chamber, and is ejected into the interior of the diffuser end together with the cold source gas;

Through the cooperation between the in-depth tube and the delivery system, the temperature of the patient's inner cavity can be quickly cooled down. And compared with the setting of the cooling method, when a delivery device is set up, the suction of the gastric heat source gas and the delivery of the cold source gas can be completed, so that the heat exchange between the gastric gases and the discharge of the heat source gas can be quickly completed without the need for structural settings, thereby increasing the survival rate of heat stroke patients on the basis of rapid cooling.

DETAILED DESCRIPTION

The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

For heat stroke patients, the most serious problem is that the core temperature of the patient is too high, and the core temperature of the patient cannot be effectively reduced in a short period of time, which causes the patient's heat production to gradually increase, causing the patient's internal organs to fail due to excessive temperature, thus endangering the patient's life safety. Therefore, when treating heat stroke patients, the following problems may occur:

1. For traditional heat stroke cooling methods, most of them use alcohol or water to wipe the patient's skin continuously, so that the patient's body surface temperature drops rapidly, thereby reducing the patient's core temperature. However, this method requires medical staff to wipe the patient's skin continuously, and this method can only act on the patient's epidermis. Heat transfer is required between the patient's core temperature and surface temperature, which makes the cooling speed and cooling efficiency relatively slow, making it easy for patients to lose the best treatment opportunity.

2. Because the core temperature of heat stroke patients is at a high level, traditional heat stroke cooling methods also include injection cooling. Injection cooling is to inject glucose or electrolyte solution into the patient to lower the patient's blood temperature; however, this intravenous injection method is also very slow, because the injection needs to take into account the tolerance of the patient's blood vessels, otherwise not only will vasospasm occur, but it will also cause extreme discomfort to the patient, making the patient prone to some complications of heat stroke, thereby aggravating the patient's heat production and worsening the patient's condition.

3. Methods of dissipating heat from the internal cavity of heat stroke patients, such as ventilators, can reduce the core temperature of patients to a certain extent, but the ventilator needs to cool down according to the patient's respiratory rate, and it is impossible to increase the patient's respiratory rate to quickly cool down the patient. Moreover, during the onset of heat stroke, the patient's respiratory system is affected by the patient's internal core temperature, making it easy for the patient to suffer from respiratory failure. Therefore, to a certain extent, it will cause the patient's respiratory rate and breathing force to decrease, further making it difficult to cool down the patient's core.

Therefore, in order to solve the above technical problems, a detection device and a method for using the detection device based on the principle of heat stroke to locate the human body cavity are provided. The following is the basic discussion of the present invention:

Because the patient's internal core temperature will rise when a heat stroke occurs, the first task is to lower the patient's internal core temperature to avoid damage to the patient's internal organs. In addition to the respiratory cavity, the inner cavity that runs through the patient's body also includes a digestive cavity, because the digestive tract starts from the mouth and ends at the rectum and runs through the entire human body, and the digestive cavity is larger than other cavities in the human body, which makes it easier to perform cooling operations. In addition, the digestive cavity in the chest and abdomen is closer to the human organs. After the digestive cavity is cooled, it can most directly exchange heat with other human organs, thereby quickly lowering the core temperature of the human body, thereby achieving the effect of quickly lowering the core temperature of the human body. Therefore, based on the above-mentioned technical problems and the setting basis of the present invention, the following structural settings are performed:

Including insertion pipe and conveying system;

Deep tube 1: extends into the patient's inner cavity and is connected to the delivery system; (For the deep tube 1 provided here, the main function is to extend the deep tube 1 into the inner cavity of the patient's digestive tract, so that the deep tube 1 is used as a medium for heat exchange between the inner cavity and the outside world to achieve the function of heat transfer.)

The conveying system includes a control system and a conveying device. The control system is connected to the conveying device to control the conveying device. The conveying device is a cooling source conveying device, and the cooling source is conveyed to the deep tube 1 through the conveying device. (The conveying system is coordinated with the deep tube 1. When the deep tube 1 is inserted into the patient's inner cavity, the cold source is conveyed through the deep tube 1 to the patient's digestive cavity through the conveying system, and heat is exchanged with the digestive cavity, thereby achieving the purpose of cooling the digestive cavity.)

After the above-mentioned deep tube 1 and the delivery system are carried out, the effect of cooling the inside of the human body cavity can be achieved. However, when setting it here, it is necessary to consider the cooling rate and the balance of the patient's inner cavity and the external air pressure. First, because the cold source is delivered to the patient's inner cavity through the deep tube 1, heat is exchanged with the inner cavity, but in the process of heat exchange, the temperature of the cold source needs to be effectively controlled. If the temperature of the delivered cold source is too cold, it will cause very serious stimulation to the patient's digestive cavity, so that the patient will have a serious condition. Second, in the case that the cold source temperature cannot be set too cold, the heat dissipation rate of the inner cavity temperature needs to be considered. If only the traditional way of heat exchange is used, the heat dissipation rate will be slow, so that the patient's large heat in the inner cavity cannot be dissipated in a short time. The third point, which is also the most important point, is that in the heat dissipation operation of the patient's inner cavity, it is not possible to cause greater damage to the patient. The core temperature of the patient should be reduced as soon as possible in the damage that the patient can bear, so as to ensure the patient's maximum survival probability.

Therefore, based on the above structure, the following structure is set:

The in-depth tube 1 includes a butt joint tube 2 and a cooling tube 3. The butt joint tube 2 is connected to the conveying device. After the cooling tube 3 is connected to the butt joint tube 2, it extends into the patient's inner cavity position; the butt joint tube 2 includes an inlet tube and an outlet tube. The inlet tube and the outlet tube are respectively butt jointed with the inlet end and the outlet end of the output device, and the two ends of the cooling tube 3 are respectively connected to the inner ports of the inlet tube and the outlet tube to form a closed pipeline. The butt joint tube 2 set here is used to dock with the conveying device. Because when setting here, the conveying device needs to replace the cooling source in real time to ensure that the heat exchange effect is maximized, so the inlet tube and the outlet tube of the butt joint tube 2 are respectively connected to the inlet end and the outlet end of the output device, so that the cold source is input at the inlet end of the butt joint tube 2, and the cold source is output after heat exchange at the outlet tube position. When setting the cooling tube 3 here, the two ends of the cooling tube 3 are respectively connected to the inlet tube and the outlet tube of the butt joint tube 2, so that a closed loop is formed between the pipelines to realize the input and output operations of the cold source.

The most important ones:

The cooling pipe 3 includes an outlet pipe 4 and an exchange pipe 5, and the outlet pipe 4 and the exchange pipe 5 are connected to the inlet pipe of the docking pipe 2 through a tee; the outlet pipe 4 is a soft straight pipe, and when the insertion pipe is inserted into the patient's digestive tract, the lower end of the outlet pipe 4 is located above the patient's esophagus; the two ends of the exchange pipe 5 are respectively connected to the inner ends of the inlet pipe and the outlet pipe to form a closed pipeline. For the outlet pipe 4 provided here, its purpose is to directly deliver the cold source to the patient's inner cavity, so the cold source here is preferably purified gas, which is delivered to the patient's interior and gives the outlet pipe 4. After the outlet pipe 4 is inserted into the patient's inner cavity, the best outlet position of the outlet pipe 4 is above the patient's esophagus, where it can cover the patient's digestive tract inner cavity with the largest area. If it is inserted into the patient's stomach, the inner cavity around the trachea will not be able to effectively exchange heat, so that the patient's inner cavity cannot be cooled to the greatest extent. As for the exchange tube 5, its function is to exchange gas with the gas inside the patient's digestive tract, and its main function is to suck the air in the patient's inner cavity; when the exchange tube 5 sucks the hotter gas in the patient's stomach, the gas that enters the esophagus from the position of the air outlet tube 4 can quickly enter the patient's stomach, which is more conducive to the diffusion of the cold source gas inside the patient. It should be noted here that although the gas in the patient's digestive tract needs to be sucked, the delivery device cannot be set up in the form of a suction pump, because it is necessary to deliver the cold source gas to the patient's inner cavity, and to suck the hotter gas in the patient's inner cavity. This requires two devices to operate at the same time to achieve, and it cannot guarantee that the cold source gas effectively covers the patient's digestive tract. Therefore, the following structural settings are made in this device:

Ejector valve ports 6 are arranged at equal intervals on the exchange tube 5, and the air in the patient's inner cavity is sucked through the ejector valve ports 6. For the ejector valve ports 6, it is possible to realize that while the delivery device delivers the cold source gas toward the inner cavity, the heat source gas in the stomach is sucked into the exchange tube 5 through the ejector valve ports 6. Thus, when using one delivery device, it is possible to realize the delivery of the cold source gas and to bring the heat source gas in the inner cavity out in time, thereby achieving the best cooling method for the patient's stomach. The specific structure of the ejector valve ports 6 is as follows:

As shown in Figure 4 of the specification, the ejector valve port 6 includes an extrusion end 7, a diffuser end 8, and a suction chamber 9, and a suction port 13 is arranged at the suction chamber 9; the diffuser end 8 is connected to the suction chamber 9, and the extrusion end 7 is arranged inside the suction chamber 9, and is arranged non-contactingly close to the diffuser end 8. As for the specific structure, the extrusion end 7 is a conical nozzle 10, and the cold source entering the exchange tube 5 flows out from the position of the conical nozzle 10 when passing through the ejector valve port 6; the diffuser end 8 is an inverted conical butt joint pipe 112, and the cold source flowing out from the conical nozzle 10 passes through the suction chamber 9 and is sprayed into the inverted conical butt joint pipe 112. The principle is,

The cold source gas is ejected at high speed from the extrusion end 7, that is, the position of the conical nozzle 10, so that the pressure energy is converted into velocity energy, and a vacuum is formed in the outlet area of the conical nozzle 10, thereby sucking out the gas in the digestion cavity. The two media are mixed and exchanged with energy in the diffusion end 8, and the velocity energy is restored to pressure energy, and finally discharged at a pressure higher than the atmospheric pressure. Therefore, when the ejector is set in principle structure, the structure of its conical nozzle 10 is as shown in Figure 4 of the specification. The diameter of the conical nozzle 10 close to the diffuser end 8 is smaller than the inner port diameter of the diffuser end 8. Then, when the high-pressure cold source gas enters the conical nozzle 10, as the diameter of the conical nozzle 10 continues to decrease, the pressure energy of the gas is converted into speed energy, that is, kinetic energy. At this time, a vacuum is formed in the outlet area of the conical nozzle 10, and the material in the chamber connected to the suction chamber 9 is sucked out of the suction chamber 9. The suction chamber 9 is provided with a suction port 13. The ejector is connected to the stomach space through the suction port 13, so that the hotter gas in the stomach is mixed with the cold source gas, and is injected into the diffuser end 8 together with the cold source gas. The diffuser end 8 is configured as an inverted conical butt joint pipe 112, so the mixed gas entering the diffuser end 8 will convert velocity energy into pressure energy through the diffuser end 8 again, and then be transported again along the exchange pipe 5, and discharged from the outlet of the butt joint pipe 2, thereby achieving the effect of rapidly reducing the stomach temperature. When the gas in the stomach space enters the exchange pipe 5, the stomach pressure is lower than the pressure above the esophagus, and the cold source gas entering the position above the esophagus from the outlet pipe 4 quickly enters the stomach environment to achieve heat exchange between the stomach gases.

As for the temperature of the cold source gas passing through, a specific structure is set for the delivery device, that is, the delivery device is connected to a temperature controller, and the temperature of the cold source gas delivered to the patient's inner cavity is regulated by the temperature controller, thereby achieving the requirement of controlling the temperature of the cold source gas.

A limiting expansion piece 12 is provided at the docking position between the docking tube 2 and the cooling tube 3, and the limiting expansion piece 12 is used to limit the expansion of the oral and pharyngeal area of the patient. The limiting expansion piece 12 can be implemented by using a traditional gastric tube dilator, and no further explanation is given here. It needs to be explained that because the exchange tube 5 needs to be inserted into the patient's stomach, but the exchange tube 5 also needs to be connected in a closed loop, after the exchange tube 5 is connected in a closed loop, the adjacent exchange tubes 5 can be connected by a connector, so that the exchange tubes 5 are arranged side by side, which makes it more convenient for medical staff to perform insertion operations.

The method for using the detection device for locating the human body cavity based on the principle of heat stroke includes the following steps:

S1, the medical staff lubricates the patient's oral cavity and throat to determine whether the patient has autonomous consciousness; if the patient has autonomous consciousness, the deep tube 1 is inserted in a normal gastric tube insertion method; if the patient has no autonomous consciousness, the deep tube 1 is inserted in an unconscious gastric tube insertion method;

S2, expanding the oral cavity and throat of the patient through the limiting expansion member 12, and inserting the penetration tube 1 into the patient's digestive tract;

S3, after inserting the penetration tube 1 into the patient's digestive tract, the inlet tube and the outlet tube of the docking tube 2 are docked and connected to the inlet end and the outlet end of the output device, respectively, to form a complete closed loop with the exchange tube 5;

S4, controlling the output device through the control system so that the output device outputs gas of suitable temperature and enters the outlet pipe 4 and the exchange pipe 5 through the inlet pipe of the docking pipe 2;

S5, the cold source gas entering the air outlet pipe 4 enters the position above the esophagus of the patient from the outlet end of the air outlet pipe 4, and gradually diffuses toward the lower digestive tract of the patient;

S6, the cold source gas entering the exchange tube 5 passes through the ejector valve body. When the high-pressure cold source gas enters the conical nozzle 10, as the diameter of the conical nozzle 10 continues to decrease, the pressure energy of the gas is converted into speed energy, i.e., kinetic energy, so that a vacuum is formed in the outlet area of the conical nozzle 10, and the stomach heat source gas connected to the suction chamber 9 is sucked out of the suction port 13 provided on the suction chamber 9, and is injected into the interior of the diffuser end 8 together with the cold source gas;

S7, the mixed gas entering the diffuser end 8 will convert velocity energy into pressure energy again through the diffuser end 8, so that it will be transported again along the exchange tube 5 and discharged outward from the outlet of the docking tube 2;

S8, when the gas in the stomach space enters the exchange tube 5, the stomach air pressure is lower than the air pressure above the esophagus, and the cold source gas that enters the position above the esophagus from the outlet pipe 4 quickly enters the stomach environment to achieve heat exchange between the stomach gases, thereby achieving rapid cooling operation of the digestive cavity.

Therefore, a detection device and a method for using the human body cavity positioning based on the principle of heat stroke are designed. The type of the patient's internal organs can be judged by the temperature of the patient's internal cavity. At the same time, the patient's internal cavity space can be effectively dissipated to ensure that the patient's internal cavity temperature can be lowered in a short time, thereby increasing the patient's chance of survival.
