TECHNICAL FIELD

[0001] The application belongs to the field of respiratory alkalosis carbon dioxide recovery, in particular to a carbon dioxide recovery device for respiratory alkalosis. BACKGROUND

[0002] Respiratory alkalosis is caused by excessive and rapid breathing, excessive ventilation of alveoli, leading to excessive decline of alveolar carbon dioxide partial pressure and excessive decline of carbon dioxide concentration in blood. There are many reasons for the patient's rapid and deep breathing, such as working and living in high altitude, underground, and other environments with thin air, constant moaning when in severe pain, emotional fluctuations, and hysteria when under mental stress, etc. can all cause excessive breathing; in addition, changes in respiratory rhythm caused by high fever, encephalitis, craniocerebral injury, and improper adjustment of inhalation and exhalation ratio during artificial respiration, etc. can all cause excessive breathing.

The application can realize real-time monitoring of carbon dioxide concentration, the inner side of the upper surface of the cover body is provided with a PH test paper, which can test the acid-base degree of breathing in the cover body, the monitoring of respiratory acid-base degree can reflect the degree of respiratory alkalosis of the patient in real time, the monitoring of carbon dioxide concentration can monitor the carbon dioxide concentration value of the patient in real time, and the first and second breathing holes can guide the adjustment of medical staff.

[0004] In the above scheme, by adjusting the adjusting plate, whether the breathing channel is opened and the size of the opening can be adjusted. Since the air entering the first breathing hole is not purified, if the patient is suffering from respiratory alkalosis due to high fever, encephalitis, or craniocerebral injury, the patient's self-immunity is very poor at this time, and there are many patients in the hospital, which causes the surrounding air to disperse a large amount of bacteria and viruses. After the patient directly inhales the air containing bacteria and viruses, the risk of aggravating the patient's condition will be increased. Therefore, the application provides a carbon dioxide recovery device for respiratory alkalosis. SUMMARY

[0016] The beneficial effects of the present application are as follows:

[0017] 1. When the patient inhales, the external air enters into the rotatable cover through the ventilation opening, and the inhaled air is filtered by the melt-blown cloth, so that the bacteria and viruses in the air cannot enter into the patient's body. When the patient exhales, the exhaled gas pushes the frame together with the melt-blown cloth to slide along the guide column, so that the inside of the rotatable cover is opened, and the patient can exhale more smoothly. Conversely, when the patient inhales, the external air enters into the rotatable cover, and the frame together with the melt-blown cloth again seals the inside of the rotatable cover due to the increase of the air pressure in the rotatable cover, so as to filter the entering air. Compared with the prior art, under the cooperation of the rotatable cover, the melt-blown cloth, the frame and the guide column, the effective filtering of the inhaled air of the patient is ensured, and the movable frame reduces the resistance of the melt-blown cloth to the patient's breathing.

[0018] 2. When the PH test paper needs to be taken out, a new PH test paper is inserted into the placing groove on the rotatable column, and then the rotatable column is rotated. With the rotation of the rotatable column, the placing groove in which the new PH test paper is placed is turned into the cover body, and another group of placing grooves in which the used PH test paper is placed are turned out of the cover body. Since the rotatable column can be rotated, the rapid replacement of the PH test paper in the cover body is realized without interrupting the treatment of the patient.

[0019] 3. When the PH test paper is taken out, the staff member pushes the slide rail outward with fingers, the slide rail drives the push plate to move along the clearance groove, and the slide rail drives the spring to move together with the movable plate, with the movement of the movable plate, the rectangular slide groove will push the drive shaft to slide along the rectangular slide groove, and the drive shaft drives the L-shaped shaft to rotate together with the limiting strip, because the limiting strip rotates, the edges of the rectangular groove are opened, until the movable plate is blocked by the drive shaft and cannot move, at this time the slide rail together with the push plate continues to move, and the spring is stretched, the push plate that continues to move will move out of the clearance groove, and the push plate pushes the PH test paper out of the rectangular groove, so as to not only facilitate the staff member to take out the PH test paper from the placing groove, but also avoid the damage of the PH test paper.

[0020] 4. When it is needed to shorten the length of the bandage, the two groups of bandage ends are pulled respectively, the bandage will move along the guide groove in the shell, and the lower end of the clamping rod is pressed by the bandage, so that the clamping rod is turned up and the U-shaped elastic sheet is compressed, until the length of the bandage is reduced to the appropriate length, under the rebounding force of the U-shaped elastic sheet, the lower end of the clamping rod is clamped in the corresponding limiting groove, so as to limit the bandage, when it is needed to lengthen the length of the bandage, the shaft one is pushed, so that the shaft one drives the clamping rod to turn up and compresses the U-shaped elastic sheet, so as to release the limiting of the clamping rod to the bandage, at this time the staff member can pull the bandage at will to lengthen the length of the bandage, therefore, through the setting of the fixing assembly, the staff member can adjust the bandage according to the size of the head of the patient, so that the device can be applied to different patients.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1

[0034] like Figures 1 to 3 As shown in the embodiment of the present invention, a carbon dioxide recovery device for respiratory alkalosis includes a cover 1, with two sets of straps symmetrically connected to the large end of the cover 1, a rotating component 3 at the small end of the cover 1 for installing pH test strips 4, a breathing channel 5 on the cover 1, a detection probe 6 inside the breathing channel 5, and an adjustment cover 7 screwed onto the breathing channel 5. The adjustment cover 7 includes: a screw-on cover 701, which is screwed onto the breathing channel 5; four sets of second breathing holes 702 at the lower end of the screw-on cover 701; four sets of ventilation openings 703 at the upper end of the screw-on cover 701; a guide post 704 fixedly installed inside the screw-on cover 701; a frame 705 slidably connected to the guide post 704; and a meltblown fabric 706 disposed inside the frame 705. Four sets of first breathing holes 501 are opened at the upper end of the breathing channel 5.

[0035] Specifically, the melt-blown cloth 706 has a decisive filtering effect on bacteria, viruses and tiny particles in the air. The cover 1, the detection probe 6 and the PH test paper 4 adopt the related structure of the carbon dioxide recovery device for respiratory alkalosis disclosed in CN111067527A. In use, the cover 1 is covered on the mouth and nose of the patient, and then the two groups of straps 2 are tightly tied at the back of the patient's head. The rotary joint cover 701 is rotated, and the second breathing hole 702 on the rotary joint cover 701 is opposite to the first breathing hole 501 at the upper end of the breathing channel 5. By rotating the rotary joint cover 701, the position of the second breathing hole 702 relative to the first breathing hole 501 is adjusted, so as to realize the opening and closing of the breathing channel 5 and the size of the opening. The PH test paper 4 can test the acidity and alkalinity of the breath in the cover 1, and the detection probe 6 can realize real-time monitoring of the carbon dioxide concentration in the cover 1. In addition, when the patient inhales, the outside air enters the rotary joint cover 701 through the air vent 703, and the melt-blown cloth 706 filters the inhaled air, so that the bacteria and viruses in the air cannot enter the patient's body. When the patient exhales, the exhaled gas will push the frame 705 together with the melt-blown cloth 706 to slide along the guide column 704, so that the inside of the rotary joint cover 701 is opened, and the patient's exhalation is more smooth. Conversely, when inhaling, the outside air enters the rotary joint cover 701, and due to the increase of the air pressure in the rotary joint cover 701, the frame 705 together with the melt-blown cloth 706 reseals the inner cavity of the rotary joint cover 701, and filters the entering air. Compared with the prior art, under the cooperation of the rotary joint cover 701, the melt-blown cloth 706, the frame 705 and the guide column 704, the moving frame 705 reduces the resistance of the melt-blown cloth 706 to the patient's breathing.

[0036] As shown in Figure 4 The rotating assembly 3 comprises a fixed plate 301 fixedly installed at the small end of the cover 1, a mounting hole 302 opened in the fixed plate 301, a rotary joint column 303 rotatably installed in the mounting hole 302, a rubber sleeve 304 wrapped on the rotary joint column 303, and two groups of placement grooves 305 symmetrically opened on the rotary joint column 303 for placing the PH test paper 4. The rubber sleeve 304 is adhered in the mounting hole 302.

[0037] Specifically, the PH test paper 4 needs to be taken out from the cover 1 during use, and then compared with the color card to obtain the pH value in the cover 1. However, the cover 1 needs to be removed from the patient's mouth and nose to take out the PH test paper 4, and then a new PH test paper 4 is replaced. This not only needs to terminate the treatment of the patient, but also causes the PH test paper 4 to be taken out and placed very inconveniently. Therefore, when the PH test paper 4 needs to be taken out, the new PH test paper 4 is inserted into the placement slot 305 on the rotating column 303, and then the rotating column 303 is rotated. With the rotation of the rotating column 303, the placement slot 305 with the new PH test paper 4 is rotated into the cover 1, and the other group of placement slots 305 with the used PH test paper 4 is rotated out of the cover 1. Since the rotating column 303 can be rotated, the PH test paper 4 in the cover 1 can be quickly replaced without terminating the treatment of the patient.

[0038] As shown in Figures 5 to 7 The rotating column 303 includes a column body 3031, a rectangular slot 3032 symmetrically provided on the column body 3031, two groups of limiting strips 3033 symmetrically provided at the two edges of the rectangular slot 3032, an L-shaped shaft 3034 fixedly connected with the limiting strips 3033, a driving shaft 3035 connected with one end of the L-shaped shaft 3034, a movable plate 3036, a rectangular sliding groove 361 provided on the movable plate 3036, the driving shaft 3035 slidingly connected with the rectangular sliding groove 361, a sliding rail 3037 movably inserted into the middle part of the movable plate 3036, a push plate 3038 fixedly connected with the middle part of the sliding rail 3037, and a spring 3039 fixedly connected with the middle part of the movable plate 3036, one end of the spring 3039 fixedly connected with the sliding rail 3037. An avoidance slot 321 is provided in the rectangular slot 3032, the push plate 3038 is located in the avoidance slot 321, the sliding rail 3037 is inserted into the column body 3031, and the L-shaped shaft 3034 is rotatably connected with the column body 3031.

[0039] Specifically, the area formed by the rectangular slot 3032 and the two sets of limiting strips 3033 is the above-mentioned placement slot 305. The PH test paper 4 will absorb the water vapor mixed in the patient's exhaled gas. As the water vapor accumulates on the PH test paper 4, the PH test paper 4 will not only change color, but also increase in humidity. The increased humidity causes the PH test paper 4 to become soft. The soft PH test paper 4 is not only not conducive to being manually removed from the placement slot 305 by the staff, but also increases the risk of the PH test paper 4 being damaged. Therefore, when the PH test paper 4 is removed, the staff pushes the slide rail 3037 outward with their fingers. The slide rail 3037 drives the push plate 3038 to move along the air avoidance slot 321 towards the PH test paper 4. At the same time, the slide rail 3037 drives the spring 3039 to move together with the movable plate 3036. As the movable plate 3036 moves, the rectangular slide groove 361 will push the drive shaft 3035, causing the drive shaft 3035 to slide along the rectangular slide groove 361. The drive shaft 3035 drives the L-shaped shaft 3034 to rotate together with the limiting strip 3033. As the limiting strip 3033 rotates, the two edges of the rectangular slot 3032 are opened. Until the movable plate 3036 is blocked by the drive shaft 3035 and cannot move, at this time the slide rail 3037 continues to move together with the push plate 3038, and the spring 3039 is stretched. The continuously moving push plate 3038 will move out of the air avoidance slot 321, and the push plate 3038 pushes the PH test paper 4 to move out of the rectangular slot 3032. Thus, it is not only convenient for the staff to remove the PH test paper 4 from the placement slot 305, but also avoids damaging the PH test paper 4.

[0040] As shown in Figure 8 The two ends of the two sets of straps 2 are connected by a connecting assembly 8. The connecting assembly 8 includes a fixed assembly 801 for fixing the end of the strap 2, a bushing 802 hinged to one set of fixed assemblies 801, a clamping groove 803 symmetrically opened in the two sides of the bushing 802, a connecting rod 804 hinged to the other set of fixed assemblies 801, and two sets of clamping heads 805 fixed on the connecting rod 804. The two sets of clamping heads 805 are inserted into the bushing 802, and the clamping head 805 is clamped in the clamping groove 803.

[0041] Specifically, the clamping head 805 is made of plastic material with good elasticity and toughness. The cover 1 is fixed on the patient's mouth and nose by tightening the strap 2. The tightening needs to be done manually, which may cause the strap 2 to be tightened and thus the cover 1 cannot be removed from the patient's mouth and nose. Therefore, when the cover 1 is fixed on the patient's mouth and nose, the two sets of fixing assemblies 801 are pushed towards each other, so that the two sets of clamping heads 805 are inserted into the insertion sleeves 802. During the insertion process, the clamping heads 805 are extruded by the ports of the insertion sleeves 802, so that the clamping heads 805 are extruded and bent. Under the elastic action of the clamping heads 805, the clamping heads 805 are clamped in the clamping grooves 803, so that the clamping heads 805 are connected with the insertion sleeves 802, thereby fixing the cover 1 on the patient's mouth and nose. Therefore, by setting the clamping heads 805 and the insertion sleeves 802, the staff can fix and loosen the cover 1 by plugging, so as to facilitate the installation and disassembly of the cover 1 by the staff.

[0042] Example two

[0043] As shown in Figure 9 Comparative Example 1, another embodiment of the present application is: the fixing assembly 801 includes: a housing 8011, a flexible plastic plate 8012 connected to the housing 8011, the flexible plastic plate 8012 is used for the hinge connection between the housing 8011 and the insertion sleeve 802 or the connecting rod 804, a guide groove 8013 provided in the housing 8011, the strap 2 is slidably connected to the guide groove 8013, a clamping rod 8014 provided in the housing 8011, a U-shaped elastic piece 8015 provided on the upper side of the clamping rod 8014, and a shaft one 8016 fixedly connected to the upper end of the clamping rod 8014, the shaft one 8016 is screwed in the housing 8011, a plurality of limiting grooves 201 are equidistantly provided on the strap 2, and the lower end of the clamping rod 8014 is clamped in the limiting groove 201.

[0044] Specifically, since the bandage 2 is tied on the head of the patient, the length of the bandage 2 required will be different for different patients, and if the length of the bandage 2 cannot be adjusted, the device will not be applicable to different patients, so when the length of the bandage 2 needs to be shortened, the two groups of bandage 2 ends are pulled respectively, the bandage 2 will move along the guide groove 8013 in the shell 8011, at the same time the lower end of the clamping rod 8014 is extruded by the bandage 2, the clamping rod 8014 is turned up and the U-shaped elastic piece 8015 is compressed, until the length of the bandage 2 is reduced to the appropriate length, under the rebounding force of the U-shaped elastic piece 8015, the lower end of the clamping rod 8014 is clamped to the corresponding limiting groove 201, the limiting of the bandage 2 is realized, when the length of the bandage 2 needs to be increased, the shaft one 8016 is actuated, the shaft one 8016 drives the clamping rod 8014 to turn up and compress the U-shaped elastic piece 8015, the limiting of the bandage 2 by the clamping rod 8014 is released, at this time the staff can pull the bandage 2 at will to extend the length of the bandage 2, so through the setting of the fixing assembly 801, the staff can adjust the bandage 2 according to the size of the head of the patient, so that the device can be applicable to different patients.

[0045] The working principle is that the cover body 1 covers the mouth and nose of the patient, the two sets of fixed assemblies 801 are pushed towards each other, the clamping heads 805 are inserted into the insertion sleeves 802, in the process of inserting the clamping heads 805 into the insertion sleeves 802, the clamping heads 805 are extruded by the ports of the insertion sleeves 802, so that the clamping heads 805 are extruded and bent, until the clamping heads 805 are clamped in the clamping grooves 803 under the elastic action of the clamping heads 805, so that the clamping heads 805 are connected with the insertion sleeves 802, thereby fixing the cover body 1 at the mouth and nose of the patient, the PH test paper 4 can test the acidity and alkalinity of the breath in the cover body 1, and the detection probe 6 can realize real-time monitoring of the carbon dioxide concentration in the cover body 1. Secondly, when the patient inhales, the external air enters the screw cover 701 through the ventilation port 703, and the inhaled air is filtered by the melt-blown cloth 706, so that bacteria and viruses in the air cannot enter the patient's body. When the patient exhales, the exhaled gas will push the frame 705 together with the melt-blown cloth 706 to slide along the guide column 704, so that the inside of the screw cover 701 is opened, and the patient can exhale more smoothly. Conversely, when inhaling, the external air enters the screw cover 701, and due to the increase of the internal pressure of the screw cover 701, the frame 705 together with the melt-blown cloth 706 again seals the inner cavity of the screw cover 701, and filters the entering air. When the PH test paper 4 needs to be taken out, a new PH test paper 4 is inserted into the placement groove 305 on the screw column 303, and then the screw column 303 is rotated. With the rotation of the screw column 303, the placement groove 305 in which the new PH test paper 4 is placed will be turned into the cover body 1, and the other set of placement grooves 305 in which the used PH test paper 4 is placed will be turned out of the cover body 1. When the PH test paper 4 is taken out, the staff pushes the sliding rail 3037 outward with the fingers, the sliding rail 3037 drives the push plate 3038 to move along the air avoidance groove 321 towards the PH test paper 4, at the same time the sliding rail 3037 drives the spring 3039 together with the movable plate 3036 to move, with the movement of the movable plate 3036, the rectangular sliding groove 361 pushes the driving shaft 3035 to slide along the rectangular sliding groove 361, and the driving shaft 3035 drives the L-shaped shaft 3034 together with the limiting strip 3033 to rotate, because the limiting strip 3033 rotates, the two edges of the rectangular groove 3032 are opened, until the movable plate 3036 is blocked by the driving shaft 3035 and cannot move. At this time, the sliding rail 3037 together with the push plate 3038 continue to move, and the spring 3039 is stretched. The continuously moving push plate 3038 will move out of the air avoidance groove 321, and the push plate 3038 pushes the PH test paper 4 out of the rectangular groove 3032.
