Description

Technical Field

[0001] The invention relates to the technical field of breathing equipment for medical personnel, and in particular to a breathing device for medical personnel for rescuing critically ill patients in an ICU based on one-way conduction. Background Art

[0002] As the number of sub-healthy people increases, the incidence of heart disease remains high. During an acute heart attack, the patient may go into shock and lose spontaneous breathing. Medical staff should immediately provide breathing assistance to ensure uninterrupted oxygen supply to the patient and prevent irreversible damage to important organs due to lack of oxygen.

[0003] In the prior art, medical staff transmit gas to the patient's mouth and nose through a respirator to achieve oxygen supply. When the medical staff holds the respirator in their mouth and blows gas, the intensity of the blown gas is relatively high, which can easily cause the pipe of the respirator to be strongly impacted, causing expansion and rupture, affecting the service life. At the same time, as the gas is blown, the patient gradually recovers spontaneous breathing. If the medical staff still blows gas strongly, it will cause discomfort to the patient, and the medical staff cannot discover the patient's recovery of breathing in time, resulting in excessive blowing of gas, affecting the patient's spontaneous breathing. In view of this, we propose a medical staff breathing device for rescuing critically ill patients in ICU based on one-way conduction. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the medical staff breathing device for rescuing critically ill ICU patients based on one-way conduction, the medical staff holds the air inlet pipe and blows gas. The gas entering the air inlet pipe drives the blowing structure to slide to the top. When the sliding distance is the maximum, the blowing structure will be compressed, so that the blowing structure opens and the buffered gas is delivered to the mask, thereby effectively preventing the air inlet pipe surface from expanding and rupturing due to excessive gas or impact force, and preventing the patient from excessively absorbing gas. It can not only increase the service life of the medical staff breathing device but also reduce the patient's lung damage.

[0015] 2. In the medical staff breathing device for rescuing critically ill patients in the ICU based on one-way conduction, when the patient exhales gas into the air outlet structure, the blowing structure will be driven to slide to the bottom, so that when the subsequent blowing structure enters the gas, more resistance is required to open the blowing structure to deliver the gas to the patient's mouth and nose. Not only can the gas delivery be gradually reduced as the patient gradually recovers to a self-sufficient breathing state, but also the discomfort caused by the patient can be reduced, and the medical staff will feel greater resistance when blowing gas again and know that the patient is able to breathe independently, thereby improving practicality; When the blowing structure is compressed, it will drive the gas storage structure to store gas, and when the gas storage structure gradually stores gas, it will drive the gas exhaled by the gas outlet structure to discharge the gas into the air, thereby effectively preventing medical staff from being too tired when blowing gas and reducing gas delivery. At the same time, it can also discharge the patient's exhaled gas to the outside of the medical staff's breathing device, thereby increasing the patient's oxygen supply and preventing the patient's exhaled gas from being exhaled near the medical staff and affecting the medical staff's ventilation.

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the prior art, medical staff transmit gas to the patient's mouth and nose through a respirator to achieve oxygen supply. When the medical staff holds the respirator in their mouth and blows gas, the intensity of the blown gas is relatively high, which can easily cause the pipe of the respirator to be strongly impacted, causing expansion and rupture, thereby affecting the service life. At the same time, as the gas blowing continues, the patient gradually recovers his or her own breathing. If the medical staff still blows gas with high intensity, it will cause discomfort to the patient, and the medical staff cannot find that the patient has recovered his or her breathing in time, resulting in excessive blowing of gas, which affects the patient's own breathing. For the embodiments of the present invention, please refer to Figures 1 to 8 A breathing device for medical staff for rescuing critically ill patients in an ICU based on one-way conduction includes an air inlet pipe 1, a mask 2 is fixedly connected to the tail of the air inlet pipe 1, a shell 3 is fixedly connected to the outer surface of the middle part of the air inlet pipe 1, an air blowing structure 400 is arranged on one side of the shell 3 close to the air inlet pipe 1, an air outlet structure 500 is arranged on the top of the shell 3, and an air storage structure 600 is arranged on the inner wall of the shell 3.

[0020] When the patient needs medical staff to breathe, the gas entering the air inlet pipe 1 is limited by the rebound force of the blowing structure 400 sliding toward the top. At the same time, the air inlet pipe 1 is connected to the inside of the mask 2. When the patient resumes spontaneous breathing, the blowing structure 400 is driven to slide toward the bottom, so that the gas entering the air inlet pipe 1 is increased and limited by the rebound force of the blowing structure 400 sliding toward the top.

[0021] In the prior art, medical personnel transmit gas to the patient's mouth and nose through a respirator to achieve oxygen supply. When the medical personnel hold the respirator in their mouth and blow gas, the intensity of the blown gas is relatively high, which can easily cause the pipe of the respirator to be strongly impacted, causing expansion and rupture, thereby affecting the service life. Moreover, if the gas is delivered to the patient too much, the patient's lungs will be damaged, affecting lung function. Therefore, the medical personnel hold the air inlet pipe 1 in their mouth and blow gas. The gas entering the air inlet pipe 1 drives the blowing structure 400 to slide toward the top. When the sliding distance is the maximum, the blowing structure 400 will be compressed, causing the blowing structure 400 to open and deliver the buffered gas to the mask 2, thereby effectively preventing the surface of the air inlet pipe 1 from expanding and rupturing due to excessive gas or impact force, and at the same time preventing the patient from excessively absorbing gas. This can not only improve the service life of the medical personnel's breathing device but also reduce the patient's lung damage.

[0022] Moreover, as the gas is blown, the patient gradually recovers his spontaneous breathing. If the medical staff still blows the gas strongly, it will cause discomfort to the patient, and the medical staff cannot find the patient's recovery of breathing in time, resulting in excessive blowing of gas, which affects the patient's spontaneous breathing. Therefore, when the patient exhales gas from the air outlet structure 500, the blowing structure 400 will be driven to slide to the bottom, which will require more resistance to open the blowing structure 400 when the subsequent air enters the gas, and when the blowing structure 400 is compressed, the gas storage structure 600 will be driven to store gas, and when the gas storage structure 600 gradually stores gas, the gas exhaled by the air outlet structure 500 will be driven to the sky. This can not only gradually reduce the gas delivery as the patient gradually recovers to a self-sufficient breathing state, but also reduce the discomfort caused to the patient, and the medical staff will feel a greater resistance when blowing gas again and know that the patient is able to breathe independently, thereby improving practicality.

[0023] In the above embodiments, the following specific structures need to be disclosed in detail: The blowing structure 400 includes a first air inlet 401, which is opened on the surface of the air inlet pipe 1. A rectangular slide groove 408 is opened on the inner wall of the shell 3 that is fixedly connected through the surface of the air inlet pipe 1. A second rectangular plate 406 is slidably connected inside the rectangular slide groove 408. A return spring 405 is fixedly connected to the bottom of the second rectangular plate 406. The end of the return spring 405 away from the second rectangular plate 406 is fixedly connected to the first rectangular plate 404. A telescopic plate 402 is fixedly connected to the bottom of the first rectangular plate 404. The side of the telescopic plate 402 is rotatably connected to a baffle 403. The top of the baffle 403 is rotatably connected to a limiting shaft 410, and the limiting shaft 410 is fixedly connected to the inner wall of the air inlet pipe 1.

[0024] First of all, please refer to Figures 1 to 7When the patient needs to be breathed by medical staff, the staff needs to wear the mask 2 on the patient's mouth and nose, and then the staff puts his mouth over the air inlet pipe 1 and blows gas into the air inlet pipe 1. At this time, the gas will encounter the baffle 403 to block it, and guide the gas from the first air inlet 401 to the inside of the shell 3. At that time, since the second rectangular plate 406 has been stuck at the top of the inner side of the rectangular slide groove 408, the first rectangular plate 404 will be pushed to the top of the shell 3 due to the resistance of the gas, and the movement of the first rectangular plate 404 will drive the return spring 4 05 is compressed, and during the compression process, the telescopic plate 402 is driven to move toward the top. The movement of the telescopic plate 402 drives the baffle 403 to swing around the limit axis 410. At this time, the baffle 403 is in the open device, and the internal gas of the shell 3 is diverted from the inside of the air inlet pipe 1 to the inside of the shell 3 and the patient is breathed by medical staff. Through this arrangement, the impact force of the gas entering can be blocked in the first time to prevent the gas from being too large or the impact force from being too large to expand and rupture the surface of the air inlet pipe 1, and at the same time, it can prevent the patient from excessively absorbing gas.

[0025] In the above embodiment, it is necessary to further increase the resistance while storing the transported gas, and the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7 The inner wall of the shell 3 is through-set, and a rectangular slide groove 408 is opened on the inner wall of the shell 3. The middle of the first rectangular plate 404 and the second rectangular plate 406 that are slidably connected to the inner wall of the shell 3 are fixedly connected with rubber 407.

[0026] Please refer to Figure 4 When the first rectangular plate 404 moves toward the top of the shell 3, the rubber 407 will be compressed, which can not only improve the resistance to the first rectangular plate 404, but also soften its own characteristics to guide the gas from the guide port 409 to the inside of the shell 3. At this time, the inner wall of the shell 3 has the gas delivered by the medical staff. Therefore, when the first rectangular plate 404 guides the gas to the inside of the shell 3, it can also divide the gas inside the shell 3. Part of the gas will be guided to the inside of the gas storage structure 600 for storage, while the other part of the gas can only flow back to the inside of the air inlet pipe 1. The first rectangular plate 404 itself has sealing properties, which can prevent the gas inside the shell 3 from being stored and affecting the patient's inhalation of gas.

[0027] In the above embodiments, in order to further block the gas and further improve the storage of the gas, it is necessary to disclose the following specific structures in detail, please refer to Figures 1 to 7A telescopic damping rod is provided inside the return spring 405. Two groups of rubbers 407 are fixedly connected to the surface of the first rectangular plate 404 fixedly connected to the bottom of the return spring 405. The rubbers 407 are attached to the inner wall of the shell 3. Four groups of rectangular slide grooves 408 are provided on the inner wall of the shell 3. The first rectangular plate 404 and the rectangular slide grooves 408 are adapted to each other. Two groups of guide ports 409 are symmetrically provided on the surface of the shell 3. A one-way valve 411 is fixedly connected to the inner wall of the intake pipe 1 fixedly connected through the bottom of the shell 3.

[0028] When the gas is delivered to the inside of the shell 3, the two groups of rubbers 407 can further improve the resistance of the first rectangular plate 404. When the first rectangular plate 404 cannot withstand the resistance, the rubber 407 will deform and guide the gas from the guide port 409 to the inside of the shell 3, so that the gas entering the shell 3 is divided into two parts, one part is collected, and the other part flows back to the inside of the air inlet pipe 1 to be guided to the patient, thereby improving practicality.

[0029] In the above embodiment, the blowing structure 400 is changed to increase the resistance. The following specific structure needs to be disclosed in detail. Please refer to Figures 1 to 7 The air outlet structure 500 includes an air outlet pipe 501, one end of the air outlet pipe 501 away from the shell 3 is fixedly connected to the surface of the mask 2, and the other end of the air outlet pipe 501 away from the mask 2 is fixedly connected to the surface of the shell 3. An air outlet 502 is provided on the surface of the shell 3, and air guide pipes 503 are hingedly connected to both sides of the shell 3.

[0030] When the patient is gradually able to breathe independently, the gas exhaled by the patient at this time will be blocked by the one-way valve 411 and can only flow out from the inside of the air outlet pipe 501, and the air inlet pipe 1 is in a closed state and the gas is not flowing. Therefore, the gas exhaled by the patient will be guided from the air outlet pipe 501 to the top of the second rectangular plate 406, and when the pressure of the gas exhaled by the patient gradually increases, the patient can breathe independently but does not need too much gas, and can slide the second rectangular plate 406 to the bottom of the shell 3. When the second rectangular plate 406 slides to the bottom of the shell 3, it will drive the first rectangular plate 404 to move, and the movement of the first rectangular plate 404 will drive the telescopic plate 402 to move. Since the telescopic plate 402 is telescopic, and when the first rectangular plate 404 slides the maximum distance in the rectangular slide groove 408, the blowing structure 400 will move as a whole to the bottom of the shell 3, and the gas enters the air inlet pipe 1 again. At this time The first rectangular plate 404 is located near the bottom of the shell 3, so the first rectangular plate 404 needs more gas pressure to open the baffle 403. When too much gas pressure is needed to push the first rectangular plate 404, the pressure will limit the output pressure and flow of the gas, so that the amount of gas that subsequently enters the mask 2 is insufficient, and the resistance of the blowing structure 400 is changed according to the gas exhaled by the patient, so that the amount of subsequent gas entering is in a relative state. When the patient exhales less gas, the first rectangular plate 404 will be subjected to less pressure and it will be easier to transport the gas to the mask 2. When the patient exhales more gas, the first rectangular plate 404 will be subjected to greater pressure and the gas flow and output pressure will be reduced, so that there will be less gas when it is transported to the inside of the mask 2. This can not only reduce the adjustment of the position of the safety valve but also improve practicality.

[0031] In the above embodiment, in order to better guide the patient's exhaled gas to the second rectangular plate 406, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 7 The air outlet 502 arranged on the top of the shell 3 is adapted to the aperture of the air outlet pipe 501. Valves are arranged inside the hinged air guide pipes 503 passing through both sides of the shell 3. The air outlet pipe 501 is arranged in an arc shape, and four groups of air guide pipes 503 are arranged along both sides of the shell 3.

[0032] When the second rectangular plate 406 moves toward the top of the shell 3, the gas at the top of the shell 3 is pushed by the second rectangular plate 406, so that the gas flows out of the device through the valve provided inside the air guide pipe 503, thereby improving practicality.

[0033] In the above embodiment, in order to swing the gas guide tube 503 into the air for storing gas, the following specific structure needs to be disclosed in detail, please refer to Figure 8The air storage structure 600 includes an air storage bag 602 , which is fixedly connected to the outer wall of the shell 3 . A second air inlet 601 is opened in the air storage bag 602 near the inside of the shell 3 .

[0034] When the rubber 407 divides the gas, part of the gas will flow from the second air inlet 601 to the inside of the air storage bag 602, and when the air storage bag 602 gradually expands, it will drive the air guide tube 503 to swing into the air, thereby preventing the patient's exhaled gas from being diverted to the position of the medical staff, and preventing the medical staff from absorbing the patient's gas during ventilation and cross-infection.

[0035] In the above embodiment, in order to store more gas, the following specific structure needs to be disclosed in detail, please refer to Figure 8 The second air inlet 601 and the air storage bag 602 are adapted to each other, the air storage bag 602 is made of plastic, and two groups of the second air inlet 601 and the air storage bag 602 are symmetrically arranged along the transverse center of the shell 3, thereby being able to increase the storage of more gas.

[0036] In the above embodiment, in order to store more gas, the following specific structure needs to be disclosed in detail, please refer to Figures 1 to 5 When the blowing structure 400 is compressed, it drives the gas storage structure 600 to store gas, and at the same time drives the exhaled gas of the gas outlet structure 500 to be discharged.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
