Description

Technical Field

[0001] The present invention relates to the technical field of medical protective clothing, and particularly to a positive pressure protective clothing system with air circulation. Background Art

[0002] After the 1980s, with the spread of blood-borne pathogens such as HBV (hepatitis B virus), HCV (hepatitis C virus), and HIV (human immunodeficiency virus), medical staff are at risk of infection at any time during treatment and surgery because they have to face the patient's blood, body fluids, and secretions that may contain viruses. Moreover, in recent years, the number of newly emerging infectious diseases that have occurred and been confirmed worldwide has been increasing almost every year.

[0003] The currently commonly used medical protective clothing is designed for the normal temperature working environment in the medical and pharmaceutical industries. The existing medical protective clothing fabrics generally coat a layer of polyurethane waterproof layer on the outer surface of the base fabric to achieve the effect of liquid repellency and barrier. However, because this kind of protective clothing needs to achieve a fully enclosed effect, medical staff will feel very stuffy after wearing it, which causes great pain to medical staff. And when the body is in a stuffy state for a long time, a lot of water vapor will be generated in the protective clothing and cannot be discharged. When the water vapor reaches the protective clothing, it will condense into water droplets. Therefore, it is often seen that medical staff are "sweating profusely" after taking off the protective clothing. This not only makes the medical staff feel bad, but also may increase the risk of getting sick. Summary of the Invention

[0004] The present invention aims to provide a positive pressure protective clothing system with air circulation, which can actively exhaust air into the protective clothing in time to solve the problem of the wearer feeling stuffy in the protective clothing.

[0005] To achieve the above object, the basic scheme of the present invention is as follows:

[0006] A positive pressure protective clothing system with air circulation, including a protective clothing body, the protective clothing body includes a cap part and a body part connected to each other. A positive pressure exhaust device, a detection element, and a control component are installed on the protective clothing body. The positive pressure exhaust device is configured with multiple exhaust modes. The positive pressure exhaust device is provided with an air inlet and an air outlet. An air filtration and disinfection unit is arranged at the air inlet. The air outlet is communicated with the inside of the protective clothing body. The protective clothing body is provided with a plurality of exhaust ports, and a one-way air outlet component is arranged at the exhaust ports. The positive pressure exhaust device can introduce external air into the protective clothing body through the air inlet and the air outlet in sequence, and discharge it outward through each exhaust port;

[0007] The detection element is used to detect the humidity inside the protective clothing body to obtain humidity data and send it to the control component. The control component is configured with a mode control subsystem, and the mode control subsystem is configured with a data processing module. The data processing module can generate a control instruction according to the humidity data, and the control instruction can control the positive pressure exhaust device to execute the corresponding exhaust mode.

[0008] Further, an air outlet of the positive pressure exhaust device is connected with a first air duct and a second air duct. Both the first air duct and the second air duct are flexible tubes. A first solenoid valve is arranged at the connection between the first air duct and the air outlet, and a second solenoid valve is arranged at the connection between the second air duct and the air outlet. The first solenoid valve and the second solenoid valve are respectively electrically connected with the control component;

[0009] The first air duct extends from the air outlet into the cap part, and the part of the first air duct placed inside the cap part is a three-dimensional spiral tube. A plurality of first air injection holes are formed in the three-dimensional spiral tube. The space enclosed by the three-dimensional spiral tube can cover the top of the wearer's head. The positive pressure exhaust device can introduce external air from the air outlet into the first air duct and spray it into the space enclosed by the three-dimensional spiral tube through the first air injection holes;

[0010] The second air duct extends from the air outlet into the body part. A plurality of second air injection holes are formed in the second air duct. The air jetting area of the second air injection holes corresponds to the chest position of the wearer. The positive pressure exhaust device can introduce external air from the air outlet into the second air duct and spray it outwards through the second air injection holes.

[0011] Further, the exhaust modes include:

[0012] Mode 1: Exhaust heat dissipation mode. In this mode, the positive pressure exhaust device is turned on, and the first solenoid valve and the second solenoid valve are turned off. The positive pressure exhaust device introduces external air into the protective clothing body in sequence through the air inlet and the air outlet, and discharges it outwards through each exhaust port;

[0013] Mode 2: Exhaust dehumidification mode. In this mode, the positive pressure exhaust device is turned on, and the first solenoid valve and the second solenoid valve are turned on. The positive pressure exhaust device introduces external air into the protective clothing body in sequence through the air inlet and the air outlet. Part of the air flow is directly discharged outwards through each exhaust port, and the other part of the air flow is respectively introduced into the first air duct and the second air duct from the air outlet, and is respectively sprayed into their respective spraying areas through each first air injection hole and the second air injection hole and then discharged outwards through the nearest exhaust port.

[0014] Further, the air flow sprayed from the first air injection holes is defined as the first air flow. In the exhaust dehumidification mode, each first air flow can be sprayed to the top of the wearer's head, the forehead part and the back of the head;

[0015] The air flow ejected from the second air jet hole is defined as the second air flow. The air flow ejection path of each second air flow inclines upward toward the direction where the jetting area is located from the second air jet hole. Moreover, the jetting inclination degree of each second air flow gradually decreases from bottom to top, and the end of the ejection path of each second air flow is close to the corresponding position of the wearer's armpit.

[0016] Furthermore, the detection element includes a first detection unit and a second detection unit. The first detection unit is located at a position corresponding to the wearer's forehead inside the cap body part. The first detection unit is used to detect the environmental humidity inside the cap body part to obtain first humidity data and send it to the control component. The second detection unit is located at a position corresponding to the wearer's armpit inside the clothing body part. The second detection unit is used to detect the environmental humidity inside the clothing body part to obtain second humidity data and send it to the control component.

[0017] Furthermore, the data processing module is configured with a first data processing strategy. The first data processing strategy can calculate an environmental humidity index based on the first humidity data and the second humidity data. The first data processing strategy is configured with a reference humidity threshold. The first data processing strategy can compare the size of the environmental humidity index with the reference humidity threshold and generate corresponding control instructions according to the comparison result.

[0018] When the environmental humidity index is less than the reference humidity threshold, the first data processing strategy generates a control instruction, and the control instruction controls the positive pressure exhaust device to execute the exhaust heat dissipation mode.

[0019] When the environmental humidity index is greater than the reference humidity threshold, the first data processing strategy generates a control instruction, and the control instruction controls the positive pressure exhaust device to execute the exhaust dehumidification mode.

[0020] Furthermore, the positive pressure exhaust device includes an exhaust air box fixedly installed on the clothing body part. The air inlet is opened on the side of the exhaust air box far from the clothing body part. The air outlet is attached to the clothing body part, and a plurality of first ventilation holes communicating with the air outlet are opened on the clothing body part.

[0021] A heat dissipation component is arranged inside the exhaust air box. The heat dissipation component includes a heat conducting sheet, a thermoelectric cooler, a radiator, and an electric fan. The heat conducting sheet and the thermoelectric cooler are respectively clamped on the side of the exhaust air box close to the clothing body part. The thermoelectric cooler is configured with a cooling surface and a heat dissipation surface. The cooling surface of the thermoelectric cooler is connected to the heat conducting sheet, and the heat dissipation surface of the thermoelectric cooler is connected to the radiator. The electric fan is installed on the radiator. A second ventilation hole is opened on the upper garment, and the electric fan can direct the external air flow to the heat dissipation fin and pass through the second ventilation hole.

[0022] Further, a barometric pressure detection element and a pressure anomaly warning component are also installed on the protective clothing body. The barometric pressure detection element is used to detect the barometric pressure inside the protective clothing body to obtain a barometric pressure value and control the component;

[0023] The data processing module is configured with a second data processing strategy. The second data processing strategy is configured with a first threshold and a second threshold, and the first threshold is different from the second threshold;

[0024] In the exhaust heat dissipation mode, the second data processing strategy compares the barometric pressure value with the first threshold. When the barometric pressure value is less than the first threshold, the control component controls the pressure anomaly warning component to perform a warning action;

[0025] In the exhaust dehumidification mode, the second data processing strategy compares the barometric pressure value with the first threshold. When the barometric pressure value is less than the second threshold, the control component controls the pressure anomaly warning component to perform a warning action.

[0026] Further, the pressure anomaly warning component includes a plurality of micro-vibrators, and the micro-vibrators are arranged at positions corresponding to the fingertips of the wearer inside the clothing body.

[0027] Further, the air filtration and disinfection unit includes a metal primary filter, a HEPA filter element, an activated carbon filter, and a photocatalyst mesh arranged in sequence in the external gas inlet direction.

[0028] Compared with the prior art, the beneficial effects of this solution are:

[0029] 1. When in use, the wearer is placed inside the protective clothing body. The positive pressure exhaust device disinfects and filters the external gas through the air filtration and disinfection unit, and then introduces the external gas into the protective clothing body through the air inlet and the air outlet in sequence. The external gas can supply oxygen to the wearer inside the protective clothing body, and can also discharge the heat of the protective clothing body and the carbon dioxide generated by the wearer's breathing outwards through each exhaust port.

[0030] 2. When the wearer is in the environment of the protective clothing body, the wearer will dissipate heat and sweat through the pores and sweat glands of the body, resulting in an increase in the temperature and humidity inside the protective clothing body. The forehead and armpit parts of the human body are the parts where the sweat glands are most developed. By detecting the humidity of the corresponding two parts inside the protective clothing through the first detection unit and the second detection unit, and combining the analysis and processing of the environmental humidity index by the control component, the positive pressure exhaust device can be controlled to execute different exhaust modes under different humidity environments inside the protective clothing, thus effectively solving the problem of the wearer feeling stuffy inside the protective clothing.

[0031] 3. In the exhaust dehumidification mode, external air is sequentially introduced into the protective clothing body through the air inlet and the air outlet. A part of the air flow is directly discharged outward through each exhaust port, and another part of the air flow is respectively introduced into the first air duct and the second air duct through the air outlet, and is sprayed to their respective spraying areas through each first spray hole and the second spray hole. Each first air flow sprayed through each first spray hole can be sprayed to the top of the wearer's head, the forehead and the back of the head, and the sweat beads staying on the wearer's head can be quickly evaporated. Each second air flow sprayed through the second spray hole can be respectively sprayed to the position where the wearer's armpit is located, so that the sweat beads staying on the wearer's armpit can be quickly evaporated, playing a role in dehumidifying and cooling the wearer.

[0032] 4. The air pressure detection element in the protective clothing body can detect the air pressure in the protective clothing body. The control component judges whether there is damage and air leakage in the protective clothing body by judging the abnormal situation of the air pressure value in different exhaust modes. When the air pressure value is abnormal, that is, when there is damage and air leakage in the protective clothing body, the control component controls the pressure abnormal warning component to execute a warning action. Since the fingertips are the parts where the most human nerve endings are distributed, when the micro vibrator vibrates, the wearer's fingertips can feel the vibration for the first time, thus prompting the wearer to replace the protective clothing in time to ensure that they are in a relatively safe environment.

[0044] The air outlet of the positive pressure exhaust device 8 is connected with a first air duct and a second air duct (not shown in the figure). Both the first air duct and the second air duct are flexible tubes. A first solenoid valve is provided at the connection between the first air duct and the air outlet, and a second solenoid valve is provided at the connection between the second air duct and the air outlet. The first solenoid valve and the second solenoid valve are respectively electrically connected to the control component 3;

[0045] The first air duct extends from the air outlet to the inside of the cap body part 11, and the part of the first air duct placed inside the cap body part 11 is a three-dimensional spiral tube. A number of first air injection holes are opened on the three-dimensional spiral tube. The space enclosed by the three-dimensional spiral tube can cover the top of the wearer's head.

The jet area of the second air injection holes corresponds to the chest position of the wearer. The positive pressure exhaust device 8 can introduce external air from the air outlet into the second air duct and spray it outwards through the second air injection holes.

[0047] The positive pressure exhaust device 8 is configured with a variety of exhaust modes, and the exhaust modes include:

[0048] Mode 1: Exhaust heat dissipation mode. In this mode, the positive pressure exhaust device 8 is turned on, the first solenoid valve and the second solenoid valve are turned off. The positive pressure exhaust device 8 introduces external air into the protective clothing body 1 successively through the air inlet 41 and the air outlet, and discharges it outwards through each exhaust port 2;

[0049] Mode 2: Exhaust dehumidification mode. In this mode, the positive pressure exhaust device 8 is turned on, the first solenoid valve and the second solenoid valve are turned on. The positive pressure exhaust device 8 introduces external air into the protective clothing body 1 successively through the air inlet 41 and the air outlet. Part of the air flow is directly discharged outwards through each exhaust port 2, and the other part of the air flow is introduced into the first air duct and the second air duct respectively from the air outlet, and is sprayed to their respective spraying areas through each first air injection hole and the second air injection hole and then discharged outwards through the nearest exhaust port 2.

[0050] The air flow sprayed from the first air injection holes is defined as the first air flow. In the exhaust dehumidification mode, each first air flow can be sprayed to the top of the wearer's head, the forehead and the back of the head;

[0051] The air flow sprayed from the second air injection holes is defined as the second air flow. The air flow spraying path of each second air flow is inclined upwards towards the direction where the jet area is located. And the spraying inclination degree of each second air flow gradually decreases from bottom to top, and the end of the spraying path of each second air flow is close to the position corresponding to the armpit of the wearer.

[0052] The detection element is used to detect the humidity inside the protective clothing body 1 to obtain humidity data and send it to the control component 3. The control component 3 is configured with a mode control subsystem, such as Figure 4As shown, the mode control subsystem is configured with a data processing module 7. The data processing module 7 can generate a control instruction 71 according to the humidity data, and the control instruction 71 can control the positive pressure exhaust device 8 to execute the corresponding exhaust mode.

[0053] The detection element includes a first detection unit 61 and a second detection unit 62. The first detection unit 61 is located at a position corresponding to the wearer's forehead within the cap body 11. The first detection unit 61 is used to detect the ambient humidity within the cap body 11 to obtain the first humidity data and send it to the control component 3. The second detection unit 62 is located at a position corresponding to the wearer's armpit within the clothing body 13. The second detection unit 62 is used to detect the ambient humidity within the clothing body 13 to obtain the second humidity data and send it to the control component 3.

[0054] The data processing module 7 is configured with a first data processing strategy. The first data processing strategy can calculate the ambient humidity index according to the first humidity data and the second humidity data. The first data processing strategy is configured with a reference humidity threshold. The first data processing strategy can compare the size of the ambient humidity index with the reference humidity threshold and generate the corresponding control instruction 71 according to the comparison result.

[0055] When the ambient humidity index is less than the reference humidity threshold, the first data processing strategy generates a control instruction 71, and the control instruction 71 controls the positive pressure exhaust device 8 to execute the exhaust heat dissipation mode.

[0056] When the ambient humidity index is greater than the reference humidity threshold, the first data processing strategy generates a control instruction 71, and the control instruction 71 controls the positive pressure exhaust device 8 to execute the exhaust dehumidification mode.

[0057] An air pressure detection element 6 and a pressure anomaly warning component are also installed on the protective clothing body 1.

The pressure anomaly warning component includes a number of micro-vibrators 9. The micro-vibrators 9 are arranged at positions corresponding to the wearer's fingertips within the clothing body.

[0058] The data processing module 7 is configured with a second data processing strategy. The second data processing strategy is configured with a first threshold and a second threshold, and the first threshold is different from the second threshold. In the exhaust heat dissipation mode, the second data processing strategy compares the air pressure value with the first threshold. When the air pressure value is less than the first threshold, the control component 3 controls the pressure anomaly warning component to execute a warning action. In the exhaust dehumidification mode, the second data processing strategy compares the air pressure value with the first threshold.

[0059] A kinetic energy recovery device is arranged at a position corresponding to the human joints on the body part 13, and the kinetic energy recovery device is electrically connected to the power supply module. The kinetic energy recovery devices are respectively arranged at the positions corresponding to the left and right knee joints, left and right femurs, left and right elbow joints, and hip joints of the human body on the body part 13. When the wearer wears the protective clothing body and walks and moves, the kinetic energy recovery devices at each joint can convert kinetic energy into electric energy and store it in the power supply module, so as to realize the self-supply of electric energy and ensure the continuous operation of the positive pressure exhaust device 8.

[0060] A support structure imitating the human body's torso shape is arranged inside the body part 13. The support structure includes a hand support frame, an upper body support frame, and a leg support frame connected in sequence; the support structure imitating the human body's torso shape is used to support the weights of the power supply module, the positive pressure exhaust device 8, and the kinetic energy recovery device, so as to reduce the load brought by the human body wearing the protective clothing.

[0061] The specific implementation method of this solution is as follows:

[0062] During use, the wearer enters the protective clothing body 1 through the wearing opening 14 of the body part 13, and then turns on the positive pressure exhaust device 8. In the exhaust and heat dissipation mode, the ventilation volume of the positive pressure exhaust device 8 is about 6L / min. The external gas is disinfected and filtered by the air filtration and disinfection unit and then imported into the protective clothing body 1 through the air inlet 41 and the air outlet in sequence. The external gas can supply oxygen to the wearer inside the protective clothing body 1, and can also discharge the heat of the protective clothing body 1 and the carbon dioxide generated by the wearer's breathing out through each exhaust port 2.

[0063] During the process of the wearer wearing the protective clothing body 1 to work, the wearer will dissipate heat and sweat through the pores and sweat glands of the body in the environment of the protective clothing body 1, resulting in an increase in the temperature and humidity inside the protective clothing body 1. The forehead and armpit parts of the human body are the parts where the sweat glands are most developed. By detecting the humidity of these two parts inside the protective clothing through the first detection unit 61 and the second detection unit 62, and combining the analysis and processing of the environmental humidity index by the control component 3, the positive pressure exhaust device 8 can be controlled to execute different exhaust modes in different humidity environments inside the protective clothing. When the environmental humidity index is less than the reference humidity threshold, the first data processing strategy generates a control instruction 71, and the control instruction 71 controls the positive pressure exhaust device 8 to execute the exhaust and heat dissipation mode; when the environmental humidity index is greater than the reference humidity threshold, the first data processing strategy generates a control instruction 71, and the control instruction 71 controls the positive pressure exhaust device 8 to execute the exhaust and dehumidification mode.

[0064] In the exhaust dehumidification mode, the positive pressure exhaust device 8 is turned on, and its ventilation volume is about 10 L / min. The first solenoid valve and the second solenoid valve are turned on. The positive pressure exhaust device 8 introduces external air into the protective clothing body 1 in sequence through the air inlet 41 and the air outlet. A part of the air flow is directly discharged outward through each exhaust port 2, and another part of the air flow is introduced into the first air duct and the second air duct respectively through the air outlet, and is sprayed to their respective spraying areas through each first spray hole and the second spray hole. Each first air flow sprayed from each first spray hole can be sprayed to the top of the wearer's head, the forehead and the back of the head. The sweat beads staying on the wearer's head can be quickly evaporated, playing a role in dehumidifying and cooling the wearer. At the same time, the evaporated sweat beads are discharged outward through the nearest exhaust port 2 in the form of water vapor along with the introduced external air;

[0065] Synchronously, each second air flow sprayed from the second spray hole can be sprayed to the position where the wearer's armpit is located respectively, so that the sweat beads staying on the wearer's armpit can be quickly evaporated, playing a role in dehumidifying and cooling the wearer. At the same time, the evaporated sweat beads are discharged outward through the nearest exhaust port 2 in the form of water vapor along with the introduced external air; By dehumidifying and cooling the two places with the most developed sweat glands of the wearer's head and armpit, the environment inside the protective clothing body 1 can be effectively cooled, and the problem that the wearer feels stuffy in the protective clothing can be solved.

[0066] During the process of the wearer wearing the protective clothing body 1, the positive pressure exhaust device 8 continuously exhausts air into the protective clothing body 1. When it operates in the exhaust heat dissipation mode or the exhaust dehumidification mode, the air pressure inside the protective clothing body 1 remains relatively constant. However, since the clothing fabric of the protective clothing body 1 is relatively thin, there will be friction between various parts of the protective clothing body 1 during use, and damage will occur after long-term use, so that the wearer is exposed to the external environment, and the relatively enclosed environment provided by the protective clothing body 1 for the wearer is damaged. Therefore, it is necessary to monitor the damage condition of the protective clothing body 1 at all times;

[0067] The air pressure detection element 6 inside the protective clothing body 1 can detect the air pressure inside the protective clothing body 1. The control component 3 judges whether there is damage and air leakage in the protective clothing body 1 by judging the abnormal situation of the air pressure value in different exhaust modes. When the air pressure value is abnormal, that is, when there is damage and air leakage in the protective clothing body 1, the control component 3 controls the pressure abnormal warning component to perform a warning action. Since the fingertips are the parts of the human body where the most nerve endings are distributed, when the micro vibrator 9 vibrates, the fingertips of the wearer can feel the vibration for the first time, so as to prompt the wearer to replace the protective clothing in time to ensure that they are in a relatively safe environment.

[0068] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
