Description

Technical Field

[0001] This invention relates to the field of humidification assistance, and more particularly to an intelligent airway humidification adjustment device for critically ill respiratory patients. Background Technology

[0002] Patients with severe respiratory illnesses often require artificial airway humidification to maintain airway moisture and avoid respiratory complications. Airway humidification devices are the core auxiliary equipment for clinical treatment.

[0003] Currently, existing humidification devices of the same type have obvious drawbacks in clinical applications, and their practicality and safety are not good.

[0004] Most existing face masks use a strap-on binding method for fixation. The manual binding operation is cumbersome, and it is difficult to control the tightness precisely, which can easily cause discomfort to the patient's face due to pressure. In addition, the fit and seal are poor, which affects the effect of humidification treatment.

[0005] Meanwhile, during the delivery of the nebulized liquid through the pipeline, due to the temperature difference between the pipeline and the environment, some of the nebulized mist is very easy to condense into liquid droplets. The condensate can easily flow directly into the patient's airway along the pipeline, which can easily cause the patient to cough violently. This can not only cause discomfort to the patient during diagnosis and treatment, but may also interfere with ventilation therapy, aggravate the patient's condition, and pose certain clinical safety risks.

[0006] In view of the shortcomings of the existing technology, there is an urgent need to design an intelligent airway humidification adjustment device with optimized structure, good fit, and the ability to avoid the risk of choking from condensate. Summary of the Invention

[0007] Purpose of the Invention: The purpose of this invention is to provide an intelligent airway humidification adjustment device that solves the problems of cumbersome operation and difficulty in accurately adjusting the tightness of existing strap-on masks, thereby alleviating facial pressure discomfort for patients, improving mask fit and sealing, and ensuring the therapeutic effect of airway humidification. Another purpose of this invention is to provide an intelligent airway humidification adjustment device that addresses the problems of condensation and backflow in existing tubing systems, which can cause coughing and other clinical safety hazards. The device improves treatment safety through anti-condensation and anti-backflow structures. Furthermore, the intelligent adjustment structure allows for adaptation to environmental conditions and patient status, adjusting humidification parameters and enhancing the device's intelligence and clinical applicability.

[0008] Technical solution: A smart airway humidification adjustment device for critically ill respiratory patients, including a base, wherein a humidification mechanism is provided on the left side of the upper surface of the base;

[0009] A breathing mechanism is provided to the right of the humidification mechanism;

[0010] A liquid removal mechanism is provided between the humidification mechanism and the breathing mechanism;

[0011] The humidification mechanism includes a housing, the bottom of which is fixedly installed on the left side of the upper surface of the base. A heating humidifier is fixedly installed inside the housing. An outlet pipe is fixedly installed at the top of the output end of the heating humidifier at the top of the housing. A gas inlet pipe is fixedly installed at the top of the input end of the heating humidifier at the top of the housing.

[0012] The breathing mechanism includes a rotating rod, the bottom end of which is rotatably mounted to the right side of the upper surface of the base via a rotating shaft. A fixed arm is fixed to the top end of the rotating rod, and a breathing mask is provided on the lower surface of the fixed arm. An air supply tube is fixedly connected to the top end of the breathing mask, and the top end of the air supply tube extends through to the top of the fixed arm. Two guide posts are fixed to the outer wall of the breathing mask, and the top ends of the guide posts extend through to the top of the fixed arm and are slidably mounted with the fixed arm.

[0013] Furthermore, the lower surface of the base is fixed with multiple casters.

[0014] Furthermore, a power supply is fixedly installed inside the housing, and a control panel is embedded in the top of the housing.

[0015] Furthermore, a turntable is fixed to the outer wall of the rotating rod, and a through-type limiting groove is opened on the upper surface of the turntable. A limiting post is fixed inside the limiting groove, and the bottom end of the limiting post is fixedly connected to the upper surface of the base.

[0016] Furthermore, a rotating ring is rotatably mounted on the outer side of the turntable via a rotating shaft. An L-shaped piece is fixed on the upper surface of the rotating ring, and a squeezing column is fixed on the inner side of the L-shaped piece. An airbag is embedded in the upper surface of the turntable. The outer wall of the airbag is fixedly connected to the outer wall of the squeezing column. A ventilation tube is fixedly connected to the top of the airbag. An airbag is fixedly fixed at the top of the ventilation tube, between the breathing mask and the fixing arm.

[0017] Furthermore, a spring is fixed between the guide post and the fixed arm.

[0018] Furthermore, a traction block is fixed to the outer wall of the rotating ring, and a rotating head is rotatably mounted on the lower surface of the traction block via a rotating shaft. An electric telescopic rod is provided in front of the rotating head, and the rear end of the output end of the electric telescopic rod is fixedly connected to the front end of the rotating head. A rotating head is fixed to the rear end of the electric telescopic rod, and the lower surface of the rotating head is rotatably mounted to the upper surface of the base via a rotating shaft.

[0019] Furthermore, the liquid removal mechanism includes a sleeve, which is fitted onto the outer wall of the gas supply pipe and the outer wall of the gas outlet pipe. Water-absorbing cotton is provided on the inner side of the sleeve, which is located on the outer wall of the gas supply pipe and the outer wall of the gas outlet pipe. A drain connector is integrally formed at the bottom of the sleeve.

[0020] Furthermore, an electric telescopic rod two is fixed to the outer wall of the sleeve, a connecting piece is fixed to the left end of the output end of the electric telescopic rod two, a push rod is fixed to the lower right side of the connecting piece, and the right end of the push rod extends through to the inner side of the sleeve and is fixed with a compression ring.

It eliminates the need for medical staff to manually bind and adjust, greatly simplifying the wearing and fixing of the mask for patients.

[0022] To address the safety hazards of traditional humidification devices where condensation and backflow of droplets due to temperature differences can cause patients to cough and worsen their condition, this device incorporates a dedicated liquid removal structure in the gas delivery path. Absorbent cotton effectively absorbs condensate generated within the pipeline due to environmental and ambient temperature differences, intercepting liquid droplets at the source and preventing condensate from entering the patient's airway with the atomized airflow. Furthermore, an electrically operated automatic liquid drainage mechanism automatically squeezes and drains condensate once the absorbent cotton is saturated, achieving centralized collection and automatic cleaning of the condensate without the need for manual disassembly and cleaning of the pipeline, thus continuously keeping the gas delivery pipeline dry and clean.

[0023] The device is equipped with a lockable movable structure at the bottom, which can flexibly move the equipment according to the patient's bed position, the layout of the examination room, and the needs of diagnosis and treatment operations, adapting to the placement and use needs of different clinical scenarios such as wards and intensive care units.

[0030] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example

[0032] like Figure 1 As shown, an intelligent airway humidification adjustment device for critically ill respiratory patients is provided, including a base 1;

[0033] Multiple casters 5 are fixed to the lower surface of the base 1;

[0034] This device allows for free movement of the entire device via multiple casters 5 at the bottom of the base 1. The device can be flexibly moved according to the patient's bed position and the needs of the treatment site. Once in place, it can be fixed by the locking structure of the casters 5 to prevent displacement during treatment, ensuring treatment stability and adapting to the placement and use needs of different clinical treatment scenarios.

[0035] like Figure 2 As shown, a humidification mechanism 2 is provided on the left side of the upper surface of the base 1;

[0036] The humidification mechanism 2 includes a housing 201. The bottom of the housing 201 is fixedly installed on the left side of the upper surface of the base 1. A heating humidifier 202 is fixedly installed inside the housing 201. An air outlet pipe 203 is fixedly installed at the top of the output end of the heating humidifier 202 at the top of the housing 201. A gas inlet pipe 204 is fixedly installed at the top of the input end of the heating humidifier 202 at the top of the housing 201.

[0037] A power supply 205 is fixedly installed inside the housing 201, and a control panel 206 is embedded in the top of the housing 201.

[0038] When the device is in use, the power supply 205 supplies power to the electrical components of the device. Medical staff can intelligently set treatment parameters such as humidification temperature, ventilation flow rate, and working time through the control panel 206 on the top of the housing 201.

[0039] An external gas source is introduced into the heated humidifier 202 through the gas inlet pipe 204. After being heated and humidified by the heated humidifier 202, it forms a constant temperature and humidity atomized gas, which is then delivered to the outside through the outlet pipe 203. This completes the pretreatment of the airway humidification gas source. The humidification parameters can be intelligently adjusted according to the patient's condition to achieve precise humidification treatment.

[0040] like Figure 3 and Figure 4 As shown, a breathing mechanism 3 is provided to the right of the humidification mechanism 2;

[0041] The breathing mechanism 3 includes a rotating rod 301. The bottom end of the rotating rod 301 is rotatably mounted to the right side of the upper surface of the base 1 via a rotating shaft. A fixed arm 302 is fixed to the top end of the rotating rod 301. A breathing mask 303 is provided on the lower surface of the fixed arm 302. An air supply tube 304 is fixedly connected to the top end of the breathing mask 303. The top end of the air supply tube 304 extends through to the top of the fixed arm 302. Two guide posts 305 are fixed to the outer wall of the breathing mask 303. The top ends of the guide posts 305 extend through to the top of the fixed arm 302 and are slidably mounted with the fixed arm 302.

[0042] A turntable 306 is fixed to the outer wall of the rotating rod 301. A through-type limiting groove 307 is provided on the upper surface of the turntable 306. A limiting post 308 is fixed inside the limiting groove 307. The bottom end of the limiting post 308 is fixedly connected to the upper surface of the base 1.

[0043] A rotating ring 309 is mounted on the outer side of the turntable 306 via a rotating shaft. An L-shaped piece 310 is fixed on the upper surface of the rotating ring 309. A compression column 319 is fixed on the inner side of the L-shaped piece 310. An airbag 311 is embedded on the upper surface of the turntable 306. The outer wall of the airbag 311 is fixedly connected to the outer wall of the compression column 319. A ventilation tube 312 is fixedly connected to the top of the airbag 311. An airbag 313 is fixedly fixed at the top of the ventilation tube 312 and between the breathing mask 303 and the fixing arm 302.

[0044] A spring 314 is fixed between the guide post 305 and the fixed arm 302;

[0045] A traction block 315 is fixed to the outer wall of the rotating ring 309. A rotating head 316 is rotatably mounted on the lower surface of the traction block 315 via a rotating shaft. An electric telescopic rod 317 is provided in front of the rotating head 316. The rear end of the output end of the electric telescopic rod 317 is fixedly connected to the front end of the rotating head 316. A rotating head 318 is fixed to the rear end of the electric telescopic rod 317. The lower surface of the rotating head 318 is rotatably mounted to the upper surface of the base 1 via a rotating shaft.

[0046] When performing the fixation procedure on the patient, first control the extension of the electric telescopic rod 317. The extension of the electric telescopic rod 317 drives the turntable 306 to rotate. Then control the rotating rod 301 to rotate together, so that the fixation arm 302 moves together. This method can control the fixation arm 302 to be in a folded state or an unfolded state. The limiting post 308 cooperates with the limiting groove 307 of the turntable 306 to limit the rotation range of the turntable 306 and avoid excessive angle adjustment.

[0047] After the limiting post 308 and the limiting groove 307 are engaged and limited, the electric telescopic rod 317 continues to extend. The electric telescopic rod 317, through its telescopic action, coordinates with the rotating head 316 and the rotating head 318 to rotate adaptively. The traction block 315 drives the rotating ring 309 to rotate, causing the squeezing post 319 on the inner side of the L-shaped plate 310 to squeeze the airbag 311. The gas inside the airbag 311 is introduced into the airbag 313 through the air exchange tube 312, causing the airbag 313 to inflate. With the elastic sliding structure of the guide post 305 and the spring 314, the fit height and tightness of the breathing mask 303 are adaptively adjusted. No manual strapping is required, achieving a flexible fit and fixation between the breathing mask 303 and the patient's face. This ensures a tight fit and avoids facial pressure injury. At the same time, the spring 314 can buffer the squeezing force generated by the slight movement of the patient's head, improving wearing comfort.

[0048] like Figure 5 As shown, a liquid removal mechanism 4 is provided between the humidification mechanism 2 and the breathing mechanism 3;

[0049] The liquid removal mechanism 4 includes a sleeve 401, which is sleeved on the outer wall of the gas supply pipe 304 and the outer wall of the gas outlet pipe 203. The inner side of the sleeve 401 and the outer wall of the gas supply pipe 304 and the outer wall of the gas outlet pipe 203 are provided with absorbent cotton 402. The bottom of the sleeve 401 is integrally formed with a liquid drain connector 403.

[0050] An electric telescopic rod 404 is fixed to the outer wall of the sleeve 401. A connecting piece 405 is fixed to the left end of the output end of the electric telescopic rod 404. A push rod 406 is fixed to the lower right side of the connecting piece 405. The right end of the push rod 406 passes through the inner side of the sleeve 401 and is fixed with a compression ring 407.

[0051] During the ventilation and humidification process of the equipment, the condensate generated in the outlet pipe 203 and the supply pipe 304 due to the temperature difference can be completely absorbed and intercepted by the absorbent cotton 402 inside the sleeve 401, effectively preventing the condensate from flowing into the patient's airway with the atomized airflow.

[0052] Once the absorbent cotton 402 is saturated, the electric telescopic rod 404 is activated. The telescopic rod 404 extends and retracts, causing the connecting plate 405 and the push rod 406 to move laterally. This, in turn, pushes the compression ring 407 to move horizontally inside the sleeve 401, squeezing the absorbent cotton 402 and expelling the condensate remaining inside. The squeezed-out liquid is then discharged through the drain connector 403 at the bottom of the sleeve 401, achieving automatic cleaning of the condensate, continuously ensuring the pipeline is dry, completely eliminating the problem of choking caused by condensate backflow, and ensuring the safe and stable conduct of humidification therapy.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
