Description

Technical Field

[0001] This invention relates to the field of assisted ventilation technology, specifically to an assisted ventilation device suitable for the treatment of sepsis patients. Background Technology

[0002] Sepsis is a systemic inflammatory response syndrome caused by infection. This condition leads to metabolic disorders and multiple organ dysfunction. Severe sepsis patients often experience respiratory failure and require assisted ventilation to maintain normal breathing, thus buying time for subsequent treatment. Currently, commonly used assisted ventilation devices mainly consist of a main unit, a mask, and connecting tubing. Their working principle is that the main unit outputs gas at an appropriate pressure and flow rate, which is then delivered to the mask via tubing, providing respiratory support to the patient.

[0003] However, existing assisted ventilation devices for sepsis patients have significant drawbacks: the patient's exhaled air contains a large amount of water vapor, which condenses at the exhaust ports of the mask's connecting tube, forming a mist. With prolonged use, this mist gradually clogs the exhaust ports, hindering gas expulsion. This leads to abnormal fluctuations in ventilation pressure, affecting not only the effectiveness of ventilation therapy but also potentially increasing the patient's respiratory burden and even causing secondary injuries. Furthermore, the condensed mist is difficult to clear quickly, requiring frequent disassembly and maintenance by healthcare personnel. This interruption of ventilation therapy increases the patient's risk of infection and significantly increases the workload of healthcare workers. Summary of the Invention

A squeezing plate is slidably connected inside the lifting cover, and the squeezing plate is fixed to the bottom of the lifting cover by a first spring. A sponge block is fixedly connected to the top of the squeezing plate, and a telescopic tube is fixedly inserted into the bottom of the squeezing plate. The lower end of the telescopic tube passes through the bottom of the lifting cover and is fixedly connected to a lifting tube. The first lifting plate is fixedly sleeved on the side wall of the lifting tube, and the lower end of the lifting tube passes through the bottom of the fixed tube. A collection box is fixedly connected to the bottom of the fixed tube, and a connecting pipe is rotatably connected to the bottom of the lifting tube. The connecting pipe communicates with the collection box, and the rotation of the lifting tube is driven by a driving mechanism. A lifting frame is connected to the bottom of the fixed tube via a lifting mechanism, and the lifting tube is rotatably connected to the lifting frame. The movement of the squeezing plate is driven by a pushing mechanism.

[0006] Preferably, the telescopic mechanism includes two symmetrically arranged sleeve rods fixedly connected to the top of the first lifting plate, and each sleeve rod has a sleeve sleeved on its side wall. The upper end of the sleeve sleeve is fixed to the bottom of the lifting cover, and the sleeve rod is connected to the sleeve sleeve through a second spring.

[0007] Preferably, the pushing mechanism includes a through hole at the bottom of the lifting cover, and a pushing rod is fixedly connected to the top of the first lifting plate.

[0008] Preferably, the lifting mechanism includes a lifting module connected to the bottom of the fixed tube, a second lifting plate is connected to the lifting module, and the lifting frame is fixed to the top of the second lifting plate.

[0009] Preferably, the driving mechanism includes a gear fixedly sleeved on the side wall of the lifting tube, and a rack is connected to the bottom of the lifting frame through a reset mechanism. The rack meshes with the gear, and the movement of the rack is achieved by a pulling mechanism.

[0010] Preferably, the reset mechanism includes a fixed block fixedly connected to the bottom of the lifting frame, and two T-shaped guide rods are fixedly connected to the side wall of the fixed block. A slider is sleeved on the side wall of the T-shaped guide rod, the slider is fixed to the rack, and a reset component is provided on the side wall of the T-shaped guide rod.

[0011] Preferably, the reset component includes a third spring sleeved on the side wall of the T-shaped guide rod, and the two ends of the third spring are respectively fixed to the fixing block and the slider.

[0012] Preferably, the pulling mechanism includes a movable rod inserted into the side wall of the fixed block, one end of the movable rod being fixed to the side wall of the rack, the other end of the movable rod being fixedly connected to a pull rope, the upper end of the pull rope being fixed to the bottom of the fixed tube, and a guide assembly being provided at the bottom of the lifting frame.

[0013] Preferably, the guide assembly includes a bracket fixedly connected to the bottom of the lifting frame, and a guide wheel is rotatably connected to the side wall of the bracket via a pivot, and the pull rope slides on the side wall of the guide wheel.

[0014] Preferably, the bottom of the collection box is provided with a drainage component, the drainage component includes a drain pipe communicating with the bottom of the collection box, and the bottom of the drain pipe is threaded with a sealing cap.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This type of auxiliary ventilation device, suitable for the treatment of sepsis patients, incorporates a cleaning mechanism. When it is necessary to clean the surface of the sealing plate and the mist inside the exhaust holes, the lifting module moves the second lifting plate and the lifting frame downwards. Simultaneously, the lifting frame moves the lifting tube downwards. When the lifting tube moves downwards, it moves the first lifting plate downwards. At this time, the sleeve slides downwards along the sleeve, and the second spring gradually returns to its original position. Simultaneously, it moves the push rod downwards along the through hole. The squeezing plate, under the action of the first spring, gradually moves downwards and returns to its original position, causing the sponge block to gradually return to its original position. After the second spring has returned to its original position, when the first lifting plate continues to move downwards, it moves the lifting cover downwards, while the first spring gradually returns to its original position, thus gradually exposing and maintaining the sponge block. The sponge block adheres to the bottom of the sealing plate and exerts pressure. When the lifting frame moves downward, it can drive the guide wheel downward through the bracket and rotating shaft. At this time, the moving rod can be moved by pulling the rope, which in turn moves the rack towards the fixed block. The third spring is compressed. After the sponge block is exposed, the rack meshes with the gear, thereby driving the gear to rotate. At the same time, the lifting tube rotates, which in turn drives the lifting cover and the sponge block to rotate through the first lifting plate and the telescopic mechanism. This allows the sponge block to absorb and clean the mist on the surface of the sealing plate. Simultaneously, the sponge block can also deform and enter the vent hole to absorb and clean the mist inside the vent hole. This facilitates the absorption and cleaning of the mist inside the vent hole, prevents vent hole blockage, ensures ventilation effect, and is safer and more reliable.

[0016] This type of auxiliary ventilation device, suitable for the treatment of sepsis patients, incorporates a drainage mechanism. After adsorption and cleaning, a lifting mechanism moves the lifting frame, lifting pipe, and lifting cover upwards to reset. This allows the lifting cover to rotate and reset, positioning the sponge block at the bottom of the sealing plate without vents. Simultaneously, the first spring is gradually compressed. As the lifting frame, lifting pipe, and first lifting plate continue to move upwards, the lifting cover abuts against the bottom of the sealing plate, causing the sleeve rod to slide into the sleeve. At the same time, the second spring is gradually compressed, driving the push rod upwards along the through hole, with its upper end abutting against the bottom of the extrusion plate. This pushes the extrusion plate upwards, squeezing the sponge block. The adsorbed mist is then collected in a collection box through the telescopic pipe, lifting pipe, and connecting pipe. When drainage is needed, the sealing cap is unscrewed, and the collected mist is discharged through the drain pipe. This facilitates convenient and quick collection and treatment of the adsorbed mist. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 This invention provides a ventilation aid suitable for the treatment of sepsis patients, including a main unit 101 and a mask 102 mounted on the ventilator body. The side wall of the mask 102 is connected to a fixing tube 103, and the fixing tube 103 is connected to the main unit 101 through a flexible tube 104. These are all known technologies in this field and will not be described in detail here.

The top of the sealing plate 12 is provided with multiple exhaust holes 13, and the fixing tube 103 is provided with a device for absorbing and cleaning the mist in the installation hole 11. The cleaning mechanism includes a first lifting plate 1401, and a lifting cover 1402 is connected to the top of the first lifting plate 1401 via a telescopic mechanism. A squeezing plate 1404 is slidably connected inside the lifting cover 1402, and the squeezing plate 1404 is fixed to the bottom of the lifting cover 1402 by a first spring 1409. A sponge block 1403 is fixedly connected to the top of the squeezing plate 1404, and a telescopic tube 1408 is fixedly inserted into the bottom of the squeezing plate 1404. The lower end of the telescopic tube 1408 passes through the bottom of the lifting cover 1402 and is fixedly connected to a lifting tube 1407. The first lifting plate 1401 is fixedly sleeved on the side wall of the lifting tube 1407, and the lower end of the lifting tube 1407 passes through the bottom of the fixed tube 103. The fixed tube 103 is fixedly connected to a collection box 1405 at its bottom, and the bottom of the lifting tube 1407 is rotatably connected to a connecting tube 1406, which communicates with the collection box 1405. The rotation of the lifting tube 1407 is driven by a drive mechanism. The bottom of the fixed tube 103 is connected to a lifting frame 403 through a lifting mechanism, and the lifting tube 1407 is rotatably connected to the lifting frame 403. The movement of the extrusion plate 1404 is driven by a pushing mechanism, which facilitates the adsorption and cleaning of the mist in the exhaust hole 13, prevents the exhaust hole 13 from becoming blocked, ensures the ventilation effect, and is safer and more reliable. In addition, it facilitates the collection and treatment of the mist after adsorption and cleaning, which is more convenient and faster.

[0021] The telescopic mechanism includes two symmetrically arranged sleeve rods 202 fixedly connected to the top of the first lifting plate 1401, and each sleeve rod 202 has a sleeve 201 sleeved on its side wall. The upper end of the sleeve 201 is fixed to the bottom of the lifting cover 1402, and the sleeve rod 202 is connected to the sleeve 201 through a second spring. After the adsorption and cleaning are completed, the lifting mechanism drives the lifting frame 403, the lifting tube 1407 and the lifting cover 1402 to move upward and reset, thereby enabling the lifting cover 1402 to rotate and reset, so that the sponge block 1403 is at the bottom of the sealing plate 12 without the exhaust hole 13. At the same time, the first spring 1409 is gradually compressed. When the lifting frame 403 and the lifting tube 1407 continue to move upward, when the lifting cover 1402 abuts against the bottom of the sealing plate 12, the sleeve rod 202 slides into the sleeve 201. At the same time, the second spring is gradually compressed.

[0022] The pushing mechanism includes a through hole 301 at the bottom of the lifting cover 1402, and a pushing rod 302 is fixedly connected to the top of the first lifting plate 1401. When the lifting cover 1402 abuts against the bottom of the sealing plate 12, and when the lifting frame 403, the lifting tube 1407 and the first lifting plate 1401 continue to move upward, the pushing rod 302 is driven to move upward along the through hole 301, and the upper end of the pushing rod 302 abuts against the bottom of the extrusion plate 1404, which can push the extrusion plate 1404 upward, thereby enabling the extrusion operation of the sponge block 1403.

[0023] The lifting mechanism includes a lifting module 401 connected to the bottom of the fixed tube 103. A second lifting plate 402 is connected to the lifting module 401, and the lifting frame 403 is fixed to the top of the second lifting plate 402. The lifting module 401 drives the second lifting plate 402 and the lifting frame 403 to lift. At the same time, the lifting frame 403 can drive the lifting tube 1407 to lift. When the lifting tube 1407 moves downward, it can drive the first lifting plate 1401 to lift.

[0024] The driving mechanism includes a gear 501 fixedly sleeved on the side wall of the lifting tube 1407, and a rack 502 connected to the bottom of the lifting frame 403 through a reset mechanism. The rack 502 is meshed with the gear 501, and the movement of the rack 502 is driven by a pulling mechanism. The rack 502 is moved by the pulling mechanism and the reset mechanism. When the rack 502 meshes with the gear 501, it can drive the gear 501 to rotate. At the same time, it drives the lifting tube 1407 to rotate, and then drives the lifting cover 1402 and the sponge block 1403 to rotate through the first lifting plate 1401 and the telescopic mechanism.

[0025] The reset mechanism includes a fixed block 602 fixedly connected to the bottom of the lifting frame 403, and two T-shaped guide rods 603 fixedly connected to the side wall of the fixed block 602. A slider 601 is sleeved on the side wall of the T-shaped guide rod 603. The slider 601 is fixed to the rack 502, and a reset component is provided on the side wall of the T-shaped guide rod 603, which guides and resets the movement of the rack 502.

[0026] The reset component includes a third spring 10 sleeved on the side wall of the T-shaped guide rod 603, and the two ends of the third spring 10 are fixed to the fixed block 602 and the slider 601 respectively, so as to play a reset function.

[0027] The pulling mechanism includes a movable rod 701 inserted into the side wall of the fixed block 602, one end of the movable rod 701 being fixed to the side wall of the rack 502, and the other end of the movable rod 701 being fixedly connected to a pull rope 702. The upper end of the pull rope 702 is fixed to the bottom of the fixed tube 103, and a guide assembly is provided at the bottom of the lifting frame 403. When the lifting frame 403 moves downward, the movable rod 701 can be pulled by the pull rope 702 to move, and the rack 502 will move towards the fixed block 602, and the third spring 10 will be compressed.

[0028] The guiding assembly includes a bracket 801 fixedly connected to the bottom of the lifting frame 403. The side wall of the bracket 801 is rotatably connected to a guide wheel 803 via a rotating shaft 802, and the pull rope 702 slides on the side wall of the guide wheel 803, which plays a guiding and conveying role for the pull rope 702.

[0029] The bottom of the collection box 1405 is equipped with a drainage component, which includes a drain pipe 901 connected to the bottom of the collection box 1405, and a sealing cap 902 is threaded to the bottom of the drain pipe 901. When it is necessary to discharge, the sealing cap 902 is unscrewed, and the collected mist water can be discharged through the drain pipe 901, which makes it easier and faster to collect and process the mist water after adsorption and cleaning.

[0030] Working principle: When it is necessary to clean the surface of the sealing plate 12 and the mist in the vent hole 13, the lifting module 401 drives the second lifting plate 402 and the lifting frame 403 to move downward. At the same time, the lifting frame 403 drives the lifting pipe 1407 to move downward. When the lifting pipe 1407 moves downward, it drives the first lifting plate 1401 to move downward. At this time, the sleeve rod 202 slides downward along the sleeve 201, and the second spring gradually returns to its original position. At the same time, it drives the push rod 302 to move downward along the through hole 301. At this time, the squeezing plate 1404 can gradually move downward and return to its original position under the action of the first spring 1409, and the sponge block 1403 gradually returns to its original position.

[0031] After the second spring has reset, when the first lifting plate 1401 continues to move downward, it can drive the lifting cover 1402 to continue to move downward, while the first spring 1409 gradually resets, so that the sponge block 1403 can be gradually exposed and kept in contact with the bottom of the sealing plate 12 with a squeezing force. When the lifting frame 403 moves downward, it can drive the guide wheel 803 to move downward through the bracket 801 and the rotating shaft 802. At this time, the moving rod 701 can be moved by the pull rope 702, and the rack 502 can be moved towards the fixed block 602, and the third spring 10 is compressed.

[0032] After the sponge block 1403 is exposed, the rack 502 meshes with the gear 501, thereby driving the gear 501 to rotate. At the same time, it drives the lifting tube 1407 to rotate, which in turn drives the lifting cover 1402 and the sponge block 1403 to rotate through the first lifting plate 1401 and the telescopic mechanism. This allows the sponge block 1403 to absorb and clean the mist on the surface of the sealing plate 12. At the same time, the sponge block 1403 can also deform and enter the exhaust hole 13 to absorb and clean the mist inside the exhaust hole 13. This facilitates the absorption and cleaning of the mist inside the exhaust hole 13, prevents the exhaust hole 13 from becoming blocked, ensures the ventilation effect, and makes it safer and more reliable.

[0033] After the adsorption and cleaning are completed, the lifting mechanism drives the lifting frame 403, lifting pipe 1407, and lifting cover 1402 to move upward and reset, thereby rotating the lifting cover 1402 to reset it, so that the sponge block 1403 is at the bottom of the sealing plate 12 without the vent hole 13. At the same time, the first spring 1409 is gradually compressed. When the lifting frame 403, lifting pipe 1407, and first lifting plate 1401 continue to move upward, when the lifting cover 1402 abuts against the bottom of the sealing plate 12, the sleeve rod 202 slides into the sleeve 201. At the same time, the second spring is gradually compressed, which drives the push... The rod 302 moves upward along the through hole 301, causing the upper end of the push rod 302 to abut against the bottom of the extrusion plate 1404, which pushes the extrusion plate 1404 upward, thereby extruding the sponge block 1403. This allows the mist adsorbed by the sponge block 1403 to enter the collection box 1405 for collection through the telescopic tube 1408, the lifting tube 1407, and the connecting tube 1406. When it is necessary to discharge, the sealing cap 902 is unscrewed, and the collected mist is discharged through the drain pipe 901. This facilitates the collection and treatment of the mist after adsorption and cleaning, making it more convenient and faster.
