Description

Technical Field

[0001] The present invention relates to a medical auxiliary device, and particularly to an integrated protective clothing with ventilation and filtration functions. Background Art

[0002] Traditional protective clothing has the following defects during use: Since the face needs to be exposed and facial protection devices such as goggles and mask faceshields need to be worn during dressing, the heads of traditional protective clothing are all open structures, and an open space is reserved at the neck position. After the user wears the facial protection device, since the current facial protection device does not completely fit the opening reserved at the top of the upper limb of the clothing body, there is a phenomenon of exposure or poor sealing at the neck position after wearing the clothing body. When using the above clothing in places with a high level of infection protection, this defect of poor sealing will cause the invasion of viruses or bacteria, resulting in a greatly reduced use effect.

[0003] To solve the above problems, in the specific operation and for users, medical staff have the following solutions: Firstly, one method is to wear a head-mounted headgear that can be combined with the protective clothing. This headgear can cover the entire head part of the protective clothing after being worn, but it has the defects of difficult breathing and poor air circulation. Another way is to put on a neck protection sleeve made of a soft material with a sealed structure outside the neck position after wearing the above clothing body. The top opening of this protection sleeve is smaller, and the bottom opening is larger, which can be worn on the neck at the top and on the shoulder position at the bottom, and can achieve a certain degree of sealing and protection for the neck position. Some medical staff also use the method of winding non-woven fabric at the connection position and then tying it firmly. No matter which of the above solutions is adopted, there are still many defects in the traditional neck protection after implementation. For example, the protection is not tight enough and there is still an infection risk. Another example is that the wearing method is complex and there is discomfort at the neck position during use. Another example is that there is an infection risk and it is not easy to put on and take off when removing the neck protection device after use. Another example is the defect of poor air circulation. In addition, after wearing traditional protective clothing, the clothes are generally not changed for several hours. Some waste gases from the user's body will be discharged into the clothing body during use. When the user breathes, it is easy to absorb these waste gases, causing discomfort in the body. And for non-ventilated protective clothing, when the labor intensity is too high after wearing, the sweat on the body cannot be discharged or dried, resulting in serious discomfort when worn on the body.

[0004] Therefore, in view of the above problems, an integrated protective suit with a ventilation and filtration function is produced, which has a simple structure, is convenient to operate, has high working and running efficiency, a high safety factor, a high protection level, is convenient to wear and take off, has smooth air circulation, obvious ventilation and air exchange effects, a wide range of applications, can effectively prevent external bacteria and viruses from entering, can be taken off independently by only one person, can prevent the body waste gas pollution of the user, reduce the discomfort caused by internal sweat, and has a tight seal. It has a broad market prospect. Summary of the Invention

[0015] The present invention has the following positive effects: The product has a simple structure and is easy to operate. Firstly, it overcomes the defect of the open structure of the head part in traditional protective clothing, and provides a protective clothing with an integrated structure. There is no opening at the head position, and a head observation window structure is adopted, which can avoid the defect that there are gaps at the head of traditional protective clothing causing bacteria and diseases to invade, and can use the observation window to observe the outside world; it avoids the defect of difficult and unsmooth breathing after wearing traditional protective clothing. An air intake and air release combination method is adopted. Air is extracted from the outside, filtered by a filter block, and then sent into the protective clothing interior, effectively isolating the invasion of external viruses. The filter block adopts the N95 level to achieve super protection, and the exhaust gas is discharged to the outside of the body through an exhaust pipe.

By adopting the method of introducing and discharging external air, a circulating air flow is formed inside the protective clothing, and filtration during air entry is achieved. The user can breathe smoothly, and at the same time, the air can be used to dry the sweat on the body. The air outlet is uniquely designed at the waist position. The whole air is introduced from the waist, released at the head, and then discharged through the waist, realizing a smooth circulation from top to bottom. In addition, the product is designed with a tightening operation at the waist position. Using a tightening rope, the position below the waist is sealed. When the body exhaust gas is discharged, it will not flow to the head breathing position in a large area. Even if there is overflowing exhaust gas entering above the waist, it will be discharged through the exhaust port above the waist by the air flow pressure pressing down from top to bottom of the head, and no unpleasant smell will be generated. In addition, the back zipper structure designed in this patent adopts a self-detaching loop sleeved on the pull head of the windproof zipper. During the process of taking off the protective clothing, only one user is required to complete the operation. A hook matching the self-detaching loop is set on the wall.

[0025] As Figure 1 、 2 、3, 4, 5, 6, 7, 8, 9 show, an integrated protective clothing with ventilation and filtration functions, including a protective clothing body 1. The protective clothing body 1 adopts a fully enclosed structure. Except for the zipper on the back and the outlet positions of the cuffs, the legs, feet and head adopt a completely sealed structure, realizing an integrated structure of the head and upper body. A sealed headgear 3 integrated with the protective clothing body 1 is provided at the top of the protective clothing body 1. The sealed headgear 3 is integrated with the protective clothing body. A transparent observation window 7 is provided at the front of the sealed headgear 3. The transparent observation window 7 is made of a transparent material, and the external view can be observed through the transparent observation window 7 without affecting the line of sight. At the same time, the lower part conducts air induction to the sealed headgear 3, achieving the effect of defogging operation and preventing the observation window from being blocked by fog. A double-layer waist connection body 4 is provided at the waist part of the protective clothing body 1. The outermost double-layer waist connection body 4 is integrated with the protective clothing. A waist tightening drawstring 6 with both ends exposed is provided inside the double-layer waist connection body 4. The waist tightening drawstring 6 is sleeved inside the double-layer waist connection body 4. A windproof zipper 8 is provided above the double-layer waist connection body 4 on the back of the protective clothing body 1. The lowest end of the zipper is located above the double-layer waist connection body 4. This design structure can prevent the exhaust gas generated by the human body from penetrating into the entire protective clothing and causing discomfort after being inhaled by the head. Ventilation and filtration devices communicating with the inside of the protective clothing body 1 are provided above the double-layer waist connection body 4 on both sides of the windproof zipper 8.

[0026] The described ventilation and filtration device includes an air inlet box body 13 and an air outlet box body 15 that are connected to the inside of the protective clothing body 1 above the double-layer waist connecting body 4 arranged on both sides of the windproof zipper 8. The two box bodies are evenly distributed on both sides of the windproof zipper 8. An air inlet 20 is provided on the outer side of the air inlet box body 13. The air inlet adopts a circular pipe embedded structure and is directly an integral structure with the air inlet box body 13. The air inlet 20 is connected to an air inlet pipe connecting pipe 23 installed inside the air inlet box body 13. The outlet position of the air inlet pipe connecting pipe 23 faces upward. A filter block 21 is arranged in the air inlet 20. The outlet of the air inlet pipe connecting pipe 23 is arranged at the outer top of the air inlet box body 13 inside the protective clothing body 1. The air inlet pipe connecting pipe 23 is connected to an air inlet pipe 24 arranged inside the protective clothing body 1. The air inlet pipe 24 is arranged on the protective clothing body 1 inside the windproof zipper 8, and a fixing device is used to fix the air inlet pipe 24 on the protective clothing body behind the zipper. The top of the air inlet pipe 24 is connected to an air outlet 28 arranged inside the sealed headgear 3. The air outlet 28 adopts a tubular connecting pipe structure fixed inside the sealed headgear 3 and can be connected to the outlet end of the air inlet pipe 24 to achieve top-limited air outlet. The air outlet direction is towards the position of the transparent observation window 7, which can perform defogging operation on the transparent observation window 7 on the premise of providing sufficient fresh air. An air outlet 22 is provided on the outer side of the air outlet box body 15. The air outlet 22 is connected to an air outlet pipe connecting pipe 32 installed inside the air outlet box body 15. The outlet position of the air outlet pipe connecting pipe 32 faces upward to ensure that during the air outlet operation, the air outlet will not be blocked due to the folds of the protective clothing or the body. If the air outlet faces the waist position of the human body, it will inevitably block the outlet position of the air outlet pipe connecting pipe 32 after the user puts on the protective clothing. Therefore, the opening of the air outlet pipe connecting pipe 32 faces upward. Due to the effect of the thickness of the air outlet box body itself, the top of the air outlet pipe interface can always be in an open state. The outlet of the air outlet pipe connecting pipe 32 is arranged at the outer top of the air outlet box body 15 inside the protective clothing body 1. The top of the air outlet pipe connecting pipe 32 is connected to the inside of the protective clothing body 1. An air inlet fan housing 14 is movably clamped on the outer side of the air inlet box body 13. An air inlet fan is installed inside the air inlet fan housing 14. A mobile power supply box 11 is fixedly installed on the top of the air inlet fan housing 14. The mobile power supply adopts an integral structure with the air inlet fan housing, which is convenient to provide wind supply for the air inlet operation in a mobile power supply mode. When the mobile power supply runs out of power, it can be quickly replaced to realize the continuous introduction of external air and will not cause discomfort of dyspnea.

[0027] The bottom of the described sealing headgear 3 and the top of the protective clothing body 1 are of an integral structure. The transparent observation window 7 is a square transparent window structure made of transparent plastic material. A notch for installing the transparent observation window 7 is provided on the sealing headgear 3. The transparent observation window 7 is connected to the inner side of the notch through a composite adhesive closed layer 35. The connection position uses a tight pasting method to ensure no air leakage and at the same time ensure the flatness of the overall connection position of the observation window. The inner layer of the double-layer waist connection body 4 is of an integral structure with the protective clothing body 1. Two waist tightening drawstring outlets 5 are provided on the outer layer of the double-layer waist connection body 4. The middle position of the waist tightening drawstring 6 is arranged between the inner layer and the outer layer of the double-layer waist connection body 4. The two ends of the waist tightening drawstring 6 are exposed outside the waist tightening drawstring outlets 5. When in use, after putting it on, the closed operation of the space below the waist is realized by tightening and knotting the waist tightening drawstring 6. The windproof zipper 8 is longitudinally arranged on the back of the protective clothing body 1. The bottom of the windproof zipper 8 is arranged above the double-layer waist connection body 4. The top of the windproof zipper 8 is arranged at the top end of the back of the sealing headgear 3. At the corresponding position of the top end of the windproof zipper 8 inside the sealing headgear 3, a head anti-pressure pad 27 is provided. The head anti-pressure pad 27 has a good effect in specific use. Specifically, setting the head anti-pressure pad 27 can play a role of a cushion for the back of the head after the user wears it. Since the air inlet pipe 24 is designed to enter the inside of the sealing headgear 3 and the top position of the windproof zipper 8 is also at the rear position of the sealing headgear 3, if the structure of the head anti-pressure pad 27 is not adopted, there will surely be a sense of oppression in the back of the head when wearing, the wall of the air inlet pipe 24 will cause oppression, and the pull head 10 of the windproof zipper 8 will also generate oppression. Especially in the state where the zipper is tightened, the sense of oppression of the pull head will be stronger. Adopting the head anti-pressure pad 27 can greatly reduce the sense of oppression. At the same time, it can realize a fixed limit for the top of the air inlet pipe 24. The air inlet pipe 24 can be sleeved between the head anti-pressure pad 27 and the protective clothing body to form a stable limit, improving the stability of the equipment. At the same time, the air outlet pipe 36 can be stably fixed and limited. Further realize the stable connection between the air outlet end of the air outlet pipe 36 and the air inlet pipe 24 between the head anti-pressure pad 27 and the protective clothing body.

[0028] A windproof sealing flap is provided on the inner side of the windproof zipper 8. The sealing flap is designed with a rubber strip.

The hook will then use the self - detachable loop 9 to perform the zipper closing operation from bottom to top. When the zipper is closed, the user quickly plugs the mobile power supply box into the air inlet fan housing 14, and uses the cooperation of the clamping block 33 and the card slot 29 to slide and plug in. After plugging in, the air inlet interface 34 corresponds to the air inlet 20. By turning on the fan switch 12, the fan in the air inlet fan housing starts to operate, and blows air to the air inlet interface 34 and the air inlet 20. The fresh external air enters the air inlet pipe adapter 23 through the air inlet 20, and during the entry process, it undergoes the filtering operation of the filter block 21, achieving purification and filtration. The filtration level of the filter block 21 reaches the N95 filtration level, and it can perform the filtration operation for several hours during the power supply operation of the mobile power supply box. When the mobile power supply box runs out of power, it can be charged. After the charging operation is completed, a new filter block 21 can be replaced for use. The outside of the filter block 21 is provided with a snap ring, which can be movably sleeved on the inner wall of the air inlet 20 to perform the filtration operation. After the external air is introduced into the air inlet pipe adapter 23 by the fan, it enters the air inlet pipe 24 through the top outlet of the air inlet pipe adapter 23, and is sent to the air outlet pipe 36 through the air inlet pipe. It is discharged from the outlet of the air outlet pipe. The air outlet pipe is arranged in the sealed hood, and its air outlet is directed towards the transparent observation window 7, which can avoid direct blowing on the user's head and can defog the observation window. When the user breathes the fresh external air, the discharged gas starts to move downward from top to bottom in the sealed hood 3. Since the top is for air supply operation, the air pressure automatically enters the upper limb position of the protective clothing body through the lower part of the sealed hood 3 and continues to move downward to the waist position. Since after the wearing operation is completed, the waist tightening drawstring 6 at the waist has been tightened and knotted, at this time the air will not continue to move downward, and can only enter the air outlet pipe adapter 32 through the top of the air outlet pipe adapter, and then enter the air outlet 22 smoothly, and use the air pressure to push open the one - way opening and closing valve piece 17. The air inside the protective clothing is discharged to the outside from the air outlet. In the whole process, the air circulation inside the protective clothing is realized, and after being filtered, it enters the inside of the protective clothing. In this way, the air inside the protective clothing circulates, and the sweat on the user's body can be dried. The air inlet speed is not too fast, and the microcirculation air will not cause harm to the body.Meanwhile, even if the body waste gas of the user is discharged out of the body, it will be restricted below the double-layer connection body 4 at the waist. Even if the waste gas overflows above the waist, it can be quickly discharged out of the body by the air pressure from top to bottom into the air outlet 22.

[0036] When taking off the protective clothing, the user assumes a squatting position, connects the self-unhooking loop 9 with the hook set outside, and then slowly assumes a standing position. The self-unhooking loop 9 drives the slider 10 to move from top to bottom to open the windproof zipper, and one person can complete the operation of taking off the protective clothing.
