Detailed Description

The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings, in which reference is made to the accompanying drawings, wherein like reference numerals refer to like elements throughout.

Embodiment 1, this embodiment provides a clean protective clothing, refer to fig. 15, including protective clothing and protective clothing integrative being provided with headgear 1, because the improvement point of this scheme does not involve other parts of protective clothing except headgear 1, so other parts of protective clothing are not shown in this scheme, its characterized in that, protective clothing is worn and is provided with waistband 2, we are located the waist position at protective clothing and are provided with waistband 2, when medical personnel wear protective clothing, make protective clothing can hug closely medical personnel's health under the constraint of waistband 2, avoid producing great gap between human body and the protective clothing, lead to medical personnel walking, when moving, protective clothing produces and rocks, influence medical personnel's normal walking;

preferably, the position behind the waist of the medical staff is fixedly provided with the ventilation box 3, the ventilation box 3 is fixedly arranged on the waist belt 2, the waist belt 2 bears the gravity of the ventilation box 3, and the normal walking of the medical staff is not affected, as shown in the attached figure 7, the ventilation box 3 is internally and vertically provided with an air supply device and an air exhaust device at intervals, when the medical staff wears the protective clothing, the detection cover body 70 is buckled at the mouth and nose of the face (the shape of the detection cover body 70 is kept to be attached to the outline of the mouth and nose of the human body, and an air cushion is arranged at the contact part of the edge of the detection cover body 70 and the face of the human body to realize the air tightness of the detection cover body 70 as shown in the attached figure 15), namely, the medical staff realizes the normal breathing and inspiration through the detection cover body 70 (the detection cover body 70 can be fixed at the head of the medical staff through, certainly, other methods can be adopted for fixing, the position of the headgear 1 corresponding to the face of the human body is made of transparent plastic material), the oxygen content in the air in the headgear 1 is reduced along with the breathing of the medical care personnel (the existing protective clothing has better sealing performance, so that the air permeability of the protective clothing is poorer, and the outside air cannot enter the headgear 1), so that when the oxygen content in the air cannot maintain normal breathing, the breathing detection device arranged in the detection cover body 70 can detect the breathing frequency of the medical care personnel, admittedly, when the oxygen content in the air in the headgear 1 is reduced, the breathing frequency of the medical care personnel can be accelerated to obtain enough oxygen, when the breathing detection device detects that the breathing frequency of the medical care personnel is accelerated to a certain degree, the micro motor 6 is controlled to start by the microcontroller (the micro motor 6 is electrically connected with the storage battery pack arranged in the ventilation box 3, the microcontroller is electrically connected with a controller loop of the micro motor 6) and drives the air supply device and the air exhaust device to start working, and under the action of the air supply device and the air exhaust device, the air in the head sleeve 1 forms convection, so that the effects of discharging the air with lower oxygen content in the head sleeve 1 outwards and sending the outside fresh air into the head sleeve 1 are rapidly realized;

the air inlet pipe 4 is arranged in the ventilation box 3 and is internally provided with a hard pipe, one end of the air inlet pipe 4 extending out of the ventilation box 3 is provided with a hose, similarly, one end of the exhaust pipe 5 in the ventilation box 3 is provided with a hard pipe, one end of the exhaust pipe extending out of the ventilation box 3 is provided with a hose, referring to the attached drawing 15, the air inlet pipe 4 enters the head sleeve 1 from the upper part of the head sleeve 1, and the exhaust pipe 5 is communicated with the lower part of the head sleeve 1;

along with the continuous feeding of the external fresh air, the oxygen content of the air in the headgear 1 gradually rises, at the moment, the oxygen content of the gas inhaled by the medical staff every time is recovered to a normal level (the oxygen content in the air is in a relatively normal range, and the medical staff can breathe normally), at the moment, the breathing detection device detects that the breathing frequency of the medical staff is reduced, so that when the breathing frequency is recovered to a normal state, the breathing detection device controls the micro motor 6 to stop working through the microcontroller electrically connected with the breathing detection device, and further the air supply device and the air exhaust device stop working;

referring to fig. 3, a compression box 7 is arranged in the ventilation box 3, the upper end of the compression box 7 is communicated with the tail end of the exhaust device, a change-over switch is arranged in the exhaust device and can realize the communication between the exhaust device and the outside or the communication between the exhaust device and the compression box 7, initially, the change-over switch is defaulted to enable the tail end of the exhaust device to be in a communication state with the outside, and the exhaust device and the compression box 7 are in an isolation state;

referring to the attached figure 2, the interior of a compression box 7 is divided into two parts through a partition plate 8, the upper part and the lower part of the compression box are communicated, a one-way compression plate 9 is vertically installed in a sliding mode in a space above the partition plate 8, a gas separation device is arranged in a space below the partition plate 8, a push plate 10 is transversely installed on the upper end face of the partition plate 8 in a sliding mode, a plurality of guide pipes 11 are communicated with one side wall of the push plate 10 of the compression box 7 and the corresponding parts of the compression box are communicated, referring to the attached figure 4, the upper ends of the guide pipes 11 are communicated with a transfer box 12 together, the transfer box 12 is communicated with a gas inlet pipe 4, referring to the attached figure 5, a pressure valve is arranged in the transfer box 12, the pressure valve is of a stepped cylinder 15 arranged in the transfer box 12, one end with the larger diameter of the stepped cylinder 15 is communicated with the gas inlet pipe 4, a pressure ball 13 is axially installed in the larger diameter part, a pressure spring 14 is connected between the pressure ball 13 and the stepped cylinder 15, and in an initial state, the pressure ball 13 is abutted against the end face of the smaller diameter part of the stepped cylinder 15 under the action of the pressure spring 14 and the stepped cylinder 15 is blocked (when the one-way compression plate 9 compresses the gas in the compression box 7 from top to bottom, the gas pressure in the transfer box 12 is not enough to overcome the acting force of the pressure spring 14 on the pressure ball 13, namely, the stepped cylinder 15 is always in a blocking state);

referring to fig. 2, the one-way compression plate 9 (the one-way compression plate 9 only allows gas to pass through the one-way compression plate 9 from above the one-way compression plate 9, and gas cannot pass through the one-way compression plate 9 from below the one-way compression plate), and the pushing plate 10 are respectively connected with an intermittent driving device arranged in the ventilation box 3, and are sequentially realized under the driving of the intermittent driving device: when the one-way compression plate 9 is driven to move downwards to the lowest end, the pushing plate 10 is driven to move towards the direction close to the guide pipe 11, the one-way compression plate 9 is driven to move upwards again to the initial position, finally the pushing plate 10 is driven to move to the initial position, and then the motion process is repeated;

specifically, when the medical staff still feels oxygen deficiency after the air supply device and the air exhaust device are started (at this time, the air exhausted from the tail end of the air exhaust device is the same as the oxygen content in the outside air, but the oxygen demand of the medical staff still cannot be met at this time), at this time, the medical staff makes the air flow exhausted from the tail end of the air exhaust device not be exhausted outwards but directly enter the space at the upper end of the compression box 7 by adjusting the switch, when we set the initial state, the one-way compression plate 9 is located at the top end of the compression box 7, when the air flow enters the compression box 7, the intermittent drive device drives the one-way compression plate 9 to move downwards and move downwards along with the one-way compression plate 9, so that the air flow entering the compression box 7 is continuously compressed, the pressure of the air in the compression box 7 is increased, and the one-way compression plate 9 is lowered to the position as shown in the attached drawing, the lower end face of the one-way compression plate 9 is just in contact with the upper end face of the pushing plate 10), the one-way compression plate 9 stops moving at the moment, and air continuously still enters the space above the one-way compression plate 9 through the tail end of the exhaust device at the moment (oxygen accounts for about 21 percent, nitrogen accounts for about 78 percent and carbon dioxide and other rare gases account for less in the conventional air, and the gas separation device in the scheme meets the following requirements: when the gas pressure is increased, the absorption of nitrogen in the air can be realized, and the more the gas pressure is, the more the nitrogen is absorbed by the gas separation device, the higher the oxygen content in the air is), at this time, the gas pressure in the compression box 7 has been increased to a certain extent and the gas separation device has realized the separation of partial nitrogen in the air, at this time, the intermittent driving device starts to drive the pushing plate 10 to move toward the direction close to the conduit 11 and push the gas which is compressed in the compression box 7 and has a higher oxygen content into the transfer box 12 through the plurality of conduits 11 (here, it is worth noting: when the pushing plate 10 moves towards the direction close to the plurality of guide pipes 11, the gas pressure in the space behind the pushing plate 10 is sharply reduced, the gas in the space above the one-way compression plate 9 enters the space surrounded by the rear part of the pushing plate 10 and the lower part of the one-way compression plate 9, the gas pressure in the transfer box 12 is increased, the pressure ball 13 is forced to move towards the direction of the compression pressure spring 14 under the action of the gas pressure, the stepped cylinder 15 is opened, so that the gas with higher oxygen content entering the transfer box 12 enters the gas inlet pipe 4 and enters the headgear 1 along with fresh air sucked from the outside under the action of the air supply device, the oxygen content in the air entering the headgear 1 is greatly increased, and the oxygen deficiency condition of medical staff can be well relieved;

when the pushing plate 10 moves from one side of the compression box 7 to the other side, the intermittent driving device does not drive the pushing plate 10 to move any more, and starts to drive the one-way compression plate 9 to move upward, and the gas in the space above the one-way compression plate 9 continuously passes through the one-way compression plate 9 from top to bottom with the upward movement of the one-way compression plate 9, so that when the one-way compression plate 9 is driven to move to the initial position (located at the topmost position in the compression box 7) by the intermittent driving device, the intermittent driving device then starts to drive the pushing plate 10 to move away from the conduit 11 so as to move to the initial position (as shown in fig. 20), and at this time, the intermittent driving device drives the one-way compression plate 9 to move downward again (it is worth noting here that in the process that when the one-way compression plate 9 starts to move upward to the initial position until the one-way compression plate 9 moves downward again to the position shown in, the air exhausted from the tail end of the air exhaust device is conveyed into the compression box 7) and then the process is repeated to separate a part of nitrogen in the air, so that the air with higher oxygen content is obtained and sufficient oxygen is provided for medical staff;

when medical personnel oxygen deficiency state is alleviated, change over switch is adjusted to the accessible this moment for discharge to the external world from the interior exhaust air of headgear 1, intermittent drive device stop work this moment (medical personnel no longer need the oxygen of higher concentration this moment, have turned off intermittent drive device and have played the purpose of power saving), so that when breathing detection device detects medical personnel's respiratory frequency and resumes to normal within range, through 6 stop work of microcontroller control micro motor, whole device stop work this moment.

Example 2, based on example 1, referring to fig. 11, a plugging plate 16 is fixed to the lower end surface of a unidirectional compression plate 9 at intervals (when the unidirectional compression plate 9 moves downward until the lower end surface contacts with the upper end surface of a push plate 10, the plugging plate 16 plugs a rectangular hole formed in a partition plate 8, the lower end surface of the plugging plate 16 is flush with the lower end surface of the partition plate 8, and at this time, the partition of two spaces above and below the partition plate 8 is achieved), when the lower end surface of the plugging plate 16 just contacts with the upper end surface of the partition plate 8, the partition of two spaces above and below the partition plate 8 is achieved, and we set that the lower end surface of the unidirectional compression plate 9 does not contact with the upper end surface of the push plate 10 yet, and the lower end surface of the plugging plate 16 just keeps flush with the upper end surface of the partition plate 8, a rack 17 fixedly installed on the lower end surface of the plugging plate 16 just meshes with a separation gear 18 matched with the rack 17 (rack 17, rack 17, The teeth of the separating gear 18 are all helical teeth to ensure smooth avoidance of tooth beating in the meshing process), when the lower end face of the unidirectional compression plate 9 continuously moves downwards to be contacted with the upper end face of the pushing plate 10, the lower end face of the blocking plate 16 is just flush with the lower end face of the partition plate 8, in the process, the rack 17 drives the rotating cylinder 19 to rotate through the separating gear 18 matched with the rack and drives the movable plate 22 to move towards the direction of the compression expansion spring 23 through the connecting rod 20 matched with the rack, so that the space below the partition plate 8 is opened (as shown in figure 12), at the moment, high-pressure gas in the space below the partition plate 8 is discharged outwards, a molecular sieve is fixedly arranged in the space below the partition plate 8, when the unidirectional compression plate 9 moves downwards under the driving of the intermittent driving device, the effect of compressing the air in the compression box 7 is achieved, and the gas pressure is increased, at this time, partial nitrogen in the air is adsorbed by utilizing the physical adsorption performance of the molecular sieve, so that when the lower end surface of the plugging plate 16 is flush with the lower end surface of the partition plate 8 (at this time, the upper and lower two spaces of the partition plate 8 are partitioned), the molecular sieve adsorbs more nitrogen and the oxygen content in the residual gas in the compression box 7 above the partition plate 8 is higher, at this time, the movable plate 22 is opened, at this time, the gas pressure in the space below the partition plate 8 is reduced, and the adsorbed nitrogen is released outwards by utilizing the desorption performance of the molecular sieve, so that the nitrogen is discharged outwards through the vent holes 24 arranged on the side wall of the bottom of the ventilation box 3;

when the pushing plate 10 pushes air with high oxygen content to the transit box 12 through the conduit 11 and enters the air inlet pipe 4 under the action of the intermittent driving device, the intermittent driving device starts to drive the one-way compression plate 9 to move upwards and synchronously move the blocking plate 16 to move upwards, and the movable plate 22 is driven to close through the rack 17, the separation gear 18, the rotary cylinder 19 and the connecting rod 20 along with the upward movement of the blocking plate 16, so that when the rack 17 is separated from the separation gear 18, the movable plate 22 which is matched with each other at the moment realizes the blocking of the space below the partition plate 8 (because the molecular sieve releases adsorbed nitrogen and discharges the nitrogen outwards through the exhaust hole 24, the next adsorption can be carried out), and we set that when the one-way compression plate 9 moves upwards to the height of the initial position, the rack 17 fixedly installed on the lower end face of the blocking plate 16 does not hinder the transverse movement of the pushing plate 10.
