Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an artificial respiration device for respiratory medicine nursing. Background Art

[0002] In actual respiratory medicine nursing work, artificial respiration first aid is a common first aid measure. Because it involves patient safety, artificial respiration first aid measures need to be taken in time. At the same time, in order to avoid cross infection, the method of artificial mouth-to-mouth artificial respiration has gradually been replaced by artificial respirators. When using artificial respirators, oxygen is pressed into the mask that is close to the patient's mouth and nose by manually pressing the air bag with fingers to achieve the purpose of artificial ventilation. The current artificial respiration device is not convenient for detecting smooth airway during exhalation of patients. Patients with blocked airways directly affect the first aid time. It is also not convenient to automatically locate the tongue. The tongue of a comatose patient is easy to block the airway, posing a safety hazard. When performing artificial respiration on the patient, it is also necessary to ensure that the patient's head is tilted up to avoid airway bending and blockage at the neck position. It is not convenient to automatically control the expansion and support of the lower jaw, and it is inconvenient for nursing staff to operate alone. Therefore, the present application provides an artificial respiration device for respiratory medicine nursing to meet the needs. Summary of the invention

[0042] like Figures 4 to 7As shown, the air delivery member 1 also includes a control one-way valve 1021 fixedly mounted on the airbag 102; the airbag 102 is connected to an air control pipe 104 through a hose; an indicator light 1041 is fixedly mounted on the air control pipe 104; a breathing mask 105 is fixedly mounted on the air control pipe 104; the breathing mask 105 is used to buckle the patient's mouth; the negative pressure generating member 2 includes a piston cylinder 201 fixedly mounted on the lower pressing plate 101; the piston cylinder 201 passes through the airbag 102; a control piston 202 is slidably sleeved on the piston cylinder 201; the control piston 2 02 is fixedly installed with a control shaft 203; the control piston 202 is slidably sleeved on the top of the piston cylinder 201; a limit ring 204 is fixedly installed at the bottom of the control piston 202, and the outer side of the limit ring 204 is an inclined surface structure; a limit plate 205 is slidably inserted on the piston cylinder 201; the limit plate 205 is an "L"-shaped structure; a positioning tension spring 206 is fixedly installed on the limit plate 205, and the end of the positioning tension spring 206 is connected to the outer side of the piston cylinder 201; the limit plate 205 is used to insert the limit ring 204; the tongue positioning member 3 includes a fixed installation on the breathing The suction shell 301 inside the mask 105; the isolation net 302 is fixedly installed on the suction shell 301; the suction shell 301 is connected to the top of the piston cylinder 201 through a hose; the tongue rubber sleeve 3011 is fixedly installed on the suction shell 301; the tongue rubber sleeve 3011 is used to sleeve the tongue, and the tongue positioning member 3 can be used in conjunction with the negative pressure generating member 2 to achieve automatic control of traction and positioning of the patient's tongue when performing artificial respiration on the patient, which can keep the patient's tongue separated from the patient's upper jaw, ensuring smooth artificial respiration. This structure can avoid comatose patients The airway obstruction caused by tongue relaxation is simple to operate and automatically controlled. It uses automatic control positioning when pressing the airbag 102 to exhale for emergency treatment, which is more practical. The air delivery part 1 can be hand-held for operation, and three return springs 103 can be used to control the rapid rebound of the airbag 102 to ensure rapid air supply. The handle between the two pressing plates 101 is pressed, and the two pressing plates 101 are moved closer to each other to squeeze the control shaft 203, so as to drive the control piston 202 to move downward, suck negative pressure, generate negative pressure through the suction shell 301, and adsorb the tongue.

[0043] like Figure 4 and Figure 8As shown, the overpressure exhaust component 4 includes an exhaust pipe 401 fixedly installed on the air control pipe 104; an anti-overpressure tension spring 402 is fixedly installed on the inner side of the exhaust pipe 401; a blocking column 403 is fixedly installed on the anti-overpressure tension spring 402; the inner side of the blocking column 403 is a sloped structure; the blocking column 403 is attached to the top of the exhaust pipe 401; the top of the exhaust pipe 401 is a sloped structure; the anti-overpressure tension spring 402 is used to pull the blocking column 403 to close and fit the top of the exhaust pipe 401. The overpressure exhaust component 4 can prevent the overpressure hidden danger caused by excessive pressure on the airbag 102 by the nursing staff during first aid, and can perform pressure relief work in time to prevent overpressure. It is safer to use, has a simple and reasonable structure, ensures that the nursing staff can easily get started, reduces the difficulty of operation, and avoids secondary damage to the patient's alveoli. The present structure is simpler and more reasonable. Once the air pressure is too high, the air pressure can push the blocking column 403 to separate from the exhaust pipe 401 to achieve pressure relief.

[0044] like Figure 4 and Fig. 9 As shown, the airway detection member 5 includes an airway stop ring 501 fixedly installed inside the air control pipe 104; an air intake detection column 502 is attached to the airway stop ring 501, and a sliding shaft 5021 is fixedly installed on the air intake detection column 502; a micro switch 503 is fixedly installed at the front end of the air intake detection column 502, and the micro switch 503 is electrically connected to the indicator light 1041; a switch baffle 504 is fixedly installed inside the air control pipe 104, and the switch baffle 504 Located in front of the micro switch 503; two through slots are provided on the switch baffle 504; a spring connecting plate 505 is fixedly installed inside the air control pipe 104; a circle of through holes is provided on the spring connecting plate 505; a sliding shaft 5021 is slidably installed on the spring connecting plate 505; the airway detection member 5 also includes an anti-mistaken touch spring 506 sleeved on the sliding shaft 5021; the elastic force of the anti-mistaken touch spring 506 is less than the tension of the anti-overpressure tension spring 402; the anti-mistaken touch spring 506 Located between the spring connecting plate 505 and the sliding shaft 5021; the inner side of the airway stop ring 501 is a slope structure; the outer side of the air intake detection column 502 is a slope structure, and the airway detection component 5 is used to detect the smoothness of the patient's airway, which can prevent the patient's airway from being blocked due to factors such as saliva and not being discovered. This structure can timely detect the patient's airway obstruction, avoid damage to the airway caused by over-pressure air, and delay treatment due to suffocation of the patient. The structure is more reasonable. This structure can prompt the nursing staff to quickly adjust the treatment plan and visualize the airway smoothness. When pressing the airbag 102, because the breathing mask 105 seals and fits the patient's mouth, if the patient's airway is blocked, when pressing the airbag 102 at this time, the air intake detection column 502 cannot be guaranteed to be separated from the airway stop ring 501 during the air pressure supply process, and the nursing staff can be prompted by the indication of the indicator light 1041.

[0045] like Figure 4 , Figures 10 to 12 As shown, the mandibular positioning member 6 includes an airbag mounting plate 601 fixedly mounted on the air control tube 104; the airbag mounting plate 601 is an elastic steel sheet structure; a rubber coating is provided on the outer side of the airbag mounting plate 601; the lower side of the airbag mounting plate 601 is used to stick to the patient's mandible; an inflatable air bag 602 is fixedly mounted on the airbag mounting plate 601; the inflatable air bag 602 is inelastic; the inflatable air bag 602 is used to support the bottom of the patient's mandible; the inflatable ventilator 7 includes a ventilator tube 701 fixedly mounted on the air control tube 104; the ventilator tube 701 is connected to the airbag 102; a threaded butt pipe 7011 is fixedly mounted on the end of the ventilator tube 701; the inflatable ventilator 7 also includes an inflatable one-way valve body 702 fixedly mounted on the inflatable air bag 602; a threaded butt pipe 7011 is threadedly connected to the inflatable one-way valve body 702; the inflatable one-way valve body 702 is connected to the inflatable air bag 602, and the inflatable ventilator 7 can be used in conjunction with the mandibular positioning member 6 to fit the patient. The mandible can be flexibly supported and limited under the mandible of the patient, so that the patient's neck can be relatively straight, the trachea can be kept unobstructed, the quality of artificial respiration can be ensured, and the method of artificially supporting the mandible of the patient to tilt the patient's head upward can be avoided, which is difficult for one person to operate. At the same time, excessive support for the mandible can easily cause the patient's mouth to close, further affecting the quality of artificial respiration. The structure is simple to operate, and the expansion air bag 602 can be quickly inflated during the initial artificial respiration intake process, which plays a role of safety limit. When the breathing mask 105 is buckled on the patient's mouth, the air bag mounting plate 601 is attached to the patient's mandible. As the air bag 102 is pressed, part of the air pressure will enter the expansion air bag 602. The threaded butt joint 7011 can be separated and disassembled from the expansion air bag 602 by rotating the threaded butt joint 7011, and the expansion check valve body 702 can be controlled to deflate to shrink the expansion air bag 602. The expansion air bag 602 that can be inflated and inflated can be adapted to different patients, and has stronger versatility.

[0046] The working principle provided by the present invention is that the tongue rubber sleeve 3011 is first used to sleeve the tongue, and at this time, the handle between the two pressing plates 101 is pressed, and the two pressing plates 101 are close to each other, squeezing the control shaft 203, so as to drive the control piston 202 to move downward, suck negative pressure, and generate negative pressure through the suction shell 301 to absorb the tongue, and as the control piston 202 moves downward, the limit ring 204 is driven to move downward, and the outer inclined surface structure of the limit ring 204 is used to make the limit plate 205 slide and insert into the limit ring 204, and the positioning pull is used. The spring 206 ensures the stability of the limit position, ensuring that the negative pressure cavity inside the piston cylinder 201 will not be disturbed when the airbag 102 is pressed later. When pressing the airbag 102, the breathing mask 105 can be buckled on the patient's mouth to supply air. During the process, the one-way valve 1021 is controlled to play the role of air intake, ensuring that the airbag 102 can be pressed continuously; when pressing the airbag 102, the airbag 102 can be controlled to quickly squeeze out air to supply air to the patient. Once the air pressure is too high, the air pressure can push the blocking column 403 to separate from the exhaust pipe 401, preventing the overpressure tension spring 402 When the airbag 102 is pressed, if the patient's airway is unobstructed, the air pressure will push open the air intake detection column 502 and separate it from the airway stop ring 501, which can drive the micro switch 503 on the air intake detection column 502 to squeeze the switch baffle 504, keeping the indicator light 1041 on for a prompt. On the contrary, if the patient's airway is blocked, the indicator light 1041 will not light up or will flash for a short time when the airbag 102 is pressed. If there is not enough air intake pressure, the air intake detection column 502 cannot be kept Separated from the airway stop ring 501 in real time; when the breathing mask 105 is buckled on the patient's mouth, the airbag mounting plate 601 is attached to the patient's lower jaw, and as the airbag 102 is pressed, part of the air pressure will enter the expansion air bag 602. By utilizing the one-way flowability of the expansion one-way valve body 702, the compression airbag 102 can be inflated without causing the air pressure in the compression airbag 102 to leak out. In addition, the inflated expansion air bag 602 can maintain the subsequent compression of the airbag 102 without taking in air, and is supported on the patient's lower jaw in real time.
