Description

Technical Field

[0001] The utility model relates to the technical field of respirators, in particular to a thermometer and hygrometer for mechanical ventilation. Background Art

[0002] Airway humidification and warming can help the respiratory tract maintain normal temperature and humidity, and ensure the normal physiological functions of the respiratory mucosa. It disperses water or solution into extremely fine particles through a humidifier or other devices and warms them, protecting the patient's airway mucosa and reducing various complications during mechanical ventilation. During mechanical ventilation, the assessment and monitoring of temperature and humidity are very important parts, providing a basis for diagnosis and treatment for medical staff during assisted ventilation and ensuring the quality of assisted ventilation.

[0003] When using a thermometer and hygrometer to monitor the temperature and humidity during assisted ventilation, since one end of the thermometer and hygrometer is connected to the breathing circuit, it is prone to move during use, thus unable to ensure that the connection between the thermometer and hygrometer and the breathing circuit interface will not become detached. Content of the Utility Model

[0004] The utility model discloses a thermometer and hygrometer for mechanical ventilation, aiming to solve the technical problem that when using a thermometer and hygrometer to monitor the temperature and humidity during assisted ventilation, since one end of the thermometer and hygrometer is connected to the breathing circuit, it is prone to move during use, thus unable to ensure that the connection between the thermometer and hygrometer and the breathing circuit interface will not become detached.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A thermometer and hygrometer for mechanical ventilation, comprising a temperature and humidity monitor and a mounting frame. An air inlet hole is opened on the upper side of the temperature and humidity monitor, and an outer upper connecting pipe is fixedly connected inside the air inlet hole. One end of the outer upper connecting pipe is fixedly connected with an inner connecting pipe, and a telescopic spring is fixedly connected to the side of the inner connecting pipe. The other end of the telescopic spring is fixedly connected with an anti-detachment clamping pipe, and the anti-detachment clamping pipe is slidably connected to the outer wall of the inner connecting pipe. Circular groove openings are equidistantly arranged on the side of the inner connecting pipe, and a plurality of balls are placed inside the circular grooves. The balls are in contact with the inner wall of the anti-detachment clamping pipe. A sealing rubber plate is fixedly connected to the side of the inner connecting pipe, and a breathing circuit clamping pipe is clamped inside the inner connecting pipe.

[0007] By providing an outer connecting pipe, an inner connecting pipe, a telescopic spring, an anti - detachment clamping pipe, a sealing rubber plate, a breathing circuit clamping pipe and a ball, when connecting the temperature and humidity monitor to the breathing circuit clamping pipe, at this time, the medical staff moves the anti - detachment clamping pipe to compress the telescopic spring, and at this time the ball moves towards the outside of the inner connecting pipe. Then, the card slot on the breathing circuit clamping pipe is aligned with the ball, and then the anti - detachment clamping pipe is released to make the telescopic spring rebound. Thus, the inner wall of the anti - detachment clamping pipe squeezes the ball, so that the outside of the breathing circuit clamping pipe receives multi - point resistance, avoiding the problem that the temperature and humidity monitor is prone to move during use, resulting in the detachment at the interface between the temperature and humidity monitor and the breathing circuit.

[0008] In a preferred embodiment, locking blocks are fixedly connected to the side of the mounting frame at equal intervals, and screw holes are formed on the sides of multiple locking blocks. The same pin is screwed into the two screw holes at the same level, and a same support rod is movably connected to the inner walls of multiple locking blocks.

[0009] In a preferred embodiment, two limiting cylinders are fixedly connected to the opposite sides of the mounting frame at equal intervals, and the same fixing block is slidably connected to the outside of the two limiting cylinders on the same side. The side of the fixing block is fixedly connected to one side of the temperature and humidity monitor.

[0010] In a preferred embodiment, two shock - absorbing springs are fixedly connected to the opposite sides of the fixing block and the mounting frame, and the shock - absorbing springs surround the outer wall of the limiting cylinder. An elastic band is fixedly connected to one side of the mounting frame and the fixing block.

[0011] By providing a mounting frame, locking blocks, pins, support rods, limiting cylinders, mounting blocks and shock - absorbing springs, when fixing the temperature and humidity monitor, at this time, the locking blocks on the mounting frame are moved to the outside of the support rod to form a wrap. After adjusting the height of the temperature and humidity monitor, the pin is screwed into the screw hole of the locking block to fix the temperature and humidity monitor. At the same time, the shock - absorbing springs on the mounting frame reduce the vibration generated by the mounting frame, avoiding damage to its internal parts due to vibration when the temperature and humidity monitor is in use.

[0012] In a preferred embodiment, a mounting opening one is formed on the side of the temperature and humidity monitor, and a display screen is fixedly connected to the inside of the mounting opening one.

[0013] In a preferred embodiment, a mounting opening two is formed on the temperature and humidity monitor, and an alarm display lamp is arranged inside the mounting opening two. Mounting openings three are formed on the side of the temperature and humidity monitor at equal intervals, and buttons are fixedly connected to the inside of multiple mounting openings three. A charging interface is formed on the temperature and humidity monitor.

[0014] In a preferred embodiment, a transmission port is provided at the bottom of the temperature and humidity monitor, and an outer lower connecting pipe is fixedly connected inside the transmission port.

[0015] As can be seen from the above, the temperature and humidity meter for mechanical ventilation provided by the present invention has the technical effect that when the temperature and humidity meter monitors the temperature and humidity during the assisted ventilation process, it avoids the easy movement during use, resulting in the detachment of the temperature and humidity meter from the respiratory circuit interface.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] A temperature and humidity meter for mechanical ventilation disclosed by the present invention is mainly applied to the scenario where when the temperature and humidity meter monitors the temperature and humidity during the assisted ventilation process, since one end of the temperature and humidity meter is connected to the respiratory circuit, it is easy to move during use, so it cannot ensure that the temperature and humidity meter will not detach from the respiratory circuit interface.

[0023] Refer to Figures 1 - 4, A thermometer and hygrometer for mechanical ventilation, comprising a temperature and humidity monitor 1 and a mounting frame 20. An air inlet hole is provided on the upper side of the temperature and humidity monitor 1, and an outer upper connecting pipe 6 is fixedly connected inside the air inlet hole. One end of the outer upper connecting pipe 6 is fixedly connected with an inner connecting pipe 7, and a telescopic spring 8 is fixedly connected to the side of the inner connecting pipe 7. The other end of the telescopic spring 8 is fixedly connected with an anti - detachment clamping pipe 9. The anti - detachment clamping pipe 9 is slidably connected to the outer wall of the inner connecting pipe 7. Circular notch openings are equidistantly provided on the side of the inner connecting pipe 7, and a plurality of ball bearings 12 are placed inside the plurality of circular notches. The ball bearings 12 are in contact with the inner wall of the anti - detachment clamping pipe 9. A sealing rubber plate 10 is fixedly connected to the side of the inner connecting pipe 7. A respiratory circuit clamping pipe 11 is clamped inside the inner connecting pipe 7. When connecting the temperature and humidity monitor 1 and the respiratory circuit clamping pipe 11, at this time, the medical staff moves the anti - detachment clamping pipe 9 to compress the telescopic spring 8. At this time, the ball bearings 12 move towards the outside of the inner connecting pipe 7. Then, the clamping groove on the respiratory circuit clamping pipe 11 is aligned with the ball bearings 12. Then, the anti - detachment clamping pipe 9 is released to make the telescopic spring 8 rebound. Thus, the inner wall of the anti - detachment clamping pipe 9 squeezes the ball bearings 12, so that the outside of the respiratory circuit clamping pipe 11 receives multi - point resistance force.

[0024] Refer to Figure 1 and Figure 2 , In a preferred embodiment, locking blocks 14 are fixedly connected equidistantly on the side of the mounting frame 20, and screw holes are provided on the sides of the plurality of locking blocks 14. The same pin 15 is screwed into the screw holes of two locking blocks at the same level. A same support rod 13 is movably connected inside the plurality of locking blocks 14.

[0025] Refer to Figure 1 and Figure 2 , In a preferred embodiment, two limiting cylinders 18 are fixedly connected equidistantly on the opposite sides of the mounting frame 20, and the same fixing block 16 is slidably connected to the outside of the two limiting cylinders 18 on the same side. The side of the fixing block 16 is fixedly connected to one side of the temperature and humidity monitor 1.

[0026] Refer to Figure 1 and Figure 2 , In a preferred embodiment, two shock - absorbing springs 19 are fixedly connected to the opposite sides of the fixing block 16 and the mounting frame 20 respectively, and the shock - absorbing springs 19 are wound around the outer wall of the limiting cylinder 18. An elastic band 17 is fixedly connected to one side of the mounting frame 20 and the fixing block 16. When fixing the temperature and humidity monitor 1, at this time, the locking blocks 14 on the mounting frame 20 are moved to the outside of the support rod 13 to form a wrap. Then, after adjusting the height of the temperature and humidity monitor 1, the pin 15 is screwed into the screw hole of the locking block 14 to fix the temperature and humidity monitor 1. At the same time, the shock - absorbing springs 19 on the mounting frame 20 reduce the vibration generated by the mounting frame 20.

[0027] Refer to Figure 1 andFigure 2 , in a preferred embodiment, an installation opening one is formed on the side of the temperature and humidity monitor 1, and a display screen 2 is fixedly connected inside the installation opening one.

[0028] Referring to Figure 1 , in a preferred embodiment, an installation opening two is formed on the upper part of the temperature and humidity monitor 1, and an alarm display lamp 3 is arranged inside the installation opening two. Installation openings three are equidistantly formed on the side of the temperature and humidity monitor 1, and a key 4 is fixedly connected inside each of the multiple installation openings three. A charging interface 5 is formed on the temperature and humidity monitor 1.

[0029] Referring to Figure 1 and Figure 2 , in a preferred embodiment, a transmission port is formed at the bottom of the temperature and humidity monitor 1, and an outer lower connecting pipe 21 is fixedly connected inside the transmission port.

[0030] Working principle: When fixing the temperature and humidity monitor 1, at this time, the locking block 14 on the mounting frame 20 is moved to the outside of the support rod 13 to form a wrap. After adjusting the height of the temperature and humidity monitor 1, the bolt 15 is screwed into the screw hole of the locking block 14 to fix the temperature and humidity monitor 1. At the same time, the shock-absorbing spring 19 on the mounting frame 20 slows down the vibration generated by the mounting frame 20. When connecting the temperature and humidity monitor 1 to the breathing circuit clamping tube 11, at this time, the medical staff moves the anti-disengagement clamping tube 9 to compress the telescopic spring 8. At this time, the ball 12 moves towards the outside of the inner connecting tube 7. Then, the card slot on the breathing circuit clamping tube 11 is aligned with the ball 12, and then the anti-disengagement clamping tube 9 is released to make the telescopic spring 8 rebound. Thus, the inner wall of the anti-disengagement clamping tube 9 squeezes the ball 12, so that the outside of the breathing circuit clamping tube 11 receives multi-point resisting forces.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
