Description

Technical Field

[0001] The present invention relates to the technical field of artificial respiration assistance equipment, and in particular to an artificial respiration assistance device suitable for first aid scenarios. Background Art

[0002] In emergency scenarios, artificial respiration is a key step for 120 emergency personnel to implement emergency treatment. At present, breathing bags are widely used as artificial respiration assistive devices at emergency sites. They are usually composed of an air inlet valve, a bag, an air outlet tube and a breathing mask. By manually squeezing the bag, the breathing bag can quickly deliver oxygen to the patient's lungs, replacing traditional mouth-to-mouth artificial respiration, improving ventilation efficiency while reducing the risk of cross-infection, and buying precious rescue time for patients.

[0003] However, the existing breathing balloons still have significant defects in practical applications, which are manifested in the following two aspects: 1. Traditional breathing bags require at least two rescuers to operate in coordination: one person needs to keep the patient's head tilted back and ensure that his mouth is open, and the other person needs to manually squeeze the bag repeatedly to provide ventilation support. In the case of limited emergency resources, this operation mode will occupy the already scarce rescue manpower, resulting in a reduction in the number of people who can perform chest compressions or other rescue measures at the same time. In addition, long-term and high-frequency squeezing of the bag can easily cause arm muscle fatigue in the operator, making it difficult to maintain stable squeezing force and frequency, thereby reducing ventilation quality; 2. During the transfer of patients to ambulances or hospitals, the patient's spontaneous breathing may not be fully restored and still needs to rely on external ventilation support, but the existing operation mode of the breathing bag is difficult to adapt to mobile scenarios. On the one hand, the bumpy vehicle or stretcher movement during transfer will cause the operator to be unable to apply force steadily, and the accuracy and continuity of the balloon squeezing action are difficult to guarantee; on the other hand, changes in the patient's body position may cause the mouth to close or the airway to deviate, making it difficult to ensure that the mouth is open.

[0020] To solve the technical problems in the background art, the following artificial respiration assistance device applicable to first-aid scenarios is provided: Combined with Figures 1-11 As shown in the figure, the artificial respiration assistance device applicable to first-aid scenarios provided by the present invention includes a breathing airbag 1, which includes a balloon 11. The outlet end of the balloon 11 is communicated with an air outlet pipe 12. A safety air valve 13 is provided on the air outlet pipe 12. An intake one-way valve 14 is provided at the inlet end of the balloon 11; A face mask 2, on both sides of which symmetrically provided with straps 21. The two ends of the straps 21 are provided with magic tape strips. An air intake connector 22 is provided on the side wall of the face mask 2. The air intake connector 22 is inserted into the air outlet pipe 12. The face mask 2 includes an upper cover body 23 and a lower cover body storage cavity 24. The upper cover body 23 is arranged on the top of the lower cover body storage cavity 24. One end of the upper cover is provided with the air intake connector 22. Straps 21 are symmetrically arranged on both sides of the upper cover body 23. A partition 25 is arranged between the upper cover body 23 and the lower cover body storage cavity 24. An air guide hole 251 is opened on one side of the partition 25 close to the air intake connector 22; A nose clip assembly 3, which includes an elastic sealing component 31 and a nose clamping component 32. The elastic sealing component 31 is arranged in the upper cover body 23 and is used to actively seal the air guide hole 251. The nose clamping component 32 is arranged in the lower cover body storage cavity 24; When the balloon 11 supplies oxygen, the elastic sealing component 31 opens the air guide hole 251 and drives the nose clamping component 32 to clamp the nose; A pressing assembly 4, which is used to clamp the balloon 11 to restrict and position the balloon 11 and reciprocally press the balloon 11; The pressing assembly 4 is arranged on the ground or installed on a stretcher assembly 5.

[0021] In the above solution: 1. During first aid, the first aid personnel connect the breathing airbag 1 to the mask 2, and the mask 2 is fixed to the patient's mouth. Before the squeezing assembly is arranged, the operator can manually squeeze the balloon to provide oxygen; after the squeezing assembly is installed on the stretcher assembly, the squeezing assembly 4 can automatically squeeze the balloon 11 to output oxygen, without the need for human intervention during first aid. In this way, the first aid personnel can quickly apply other first aid measures, such as pressing the chest and arranging a stretcher to quickly transfer the patient to the hospital; 2. When supplying oxygen, the gas squeezed out by the breathing airbag 1 can flush open the elastic sealing component 31, and the elastic sealing component 31 drives the nose clamping component 32 to clamp the patient's nose, so that the operation of pinching the nose during artificial assisted breathing can be simulated, so that the filled gas can fully enter the patient's mouth without being discharged from the nose in large quantities; when not supplying oxygen, when the breathing airbag 1 is released, the elastic sealing component can be gradually reset, and the nose clamping component 32 can be gradually loosened, so that the nose is gradually opened, and the gas in the human body can be released normally; The mask 2 is designed with large, medium and small sizes, and the nose clip assembly 3 inside it can also be adaptively adjusted in size to meet the needs of different adults.

[0022] 3. The bite square tube 26 can be extended into the patient's mouth, thereby stretching the patient's mouth open, so that the gas squeezed into the breathing airbag 1 can fully enter the patient's mouth, and no special person is needed to watch and keep the mouth open; at the same time, the patient bites the bite square tube 26 to avoid biting the tongue; the rubber sleeve 262 at the bottom of the bite square tube 26 can protect the patient's teeth; the notch 261 at the top of the bite square tube 26 can leave moving space for the interference structure at the bottom of the elastic sealing component 31.

[0023] In order to enable the elastic sealing component 31 to achieve the above-mentioned function, the following solution is provided: the elastic sealing component 31 includes a baffle 311, a sealing plate 312 is vertically provided at the bottom end of the baffle 311, and the baffle 311 and the sealing plate 312 are L-shaped, and the sealing plate 312 covers the top of the air guide hole 251. The two sides of the baffle 311 are independent air intake chambers 231 and storage chambers 232. The air intake chamber 231 is connected to the air intake connector 22. A spring rod 313 is installed inside the storage chamber 232, and the outer end of the spring rod 313 is connected to the baffle 311; a vertical rod 314 is vertically provided on the bottom surface of the sealing plate 312, and a resistance block 315 is vertically provided at the bottom end of the vertical rod 314, and the resistance block 315 extends toward one side of the storage chamber.

[0024] The gas squeezed into the balloon 11 enters the storage chamber and then moves against the baffle 311. The baffle 311 moves and squeezes the spring rod 313. The elastic force of the spring rod 313 matches the squeezed air pressure of the balloon 11. When the baffle 311 moves, it can drive the sealing plate 312 to move and open the air guide hole 251. The sealing plate 312 drives the vertical rod 314 below to follow the translation, and the resistance block 315 moves and extends the notch 261 outward. When the airbag is not supplied with air, the spring rod 313 drives the baffle 311 to reset, and the sealing plate 312 closes the air guide hole 251.

[0025] In order to enable the nose clamping component 32 to respond quickly and close the nose, the following solution is provided: the clamping component includes a top block body 321 and a clamping rod 323, the top block body 321 is arranged on the bottom surface of the partition 25, and a pendulum column 322 is symmetrically mounted on the bottom of the top block body 321 for rotation, one end of the clamping rod 323 is a mating end, and the other end is a clamping end, and the bottom end of the pendulum column 322 is connected to the mating end of the clamping rod 323, and the two groups of clamping rods 323 are arranged in a V shape, and the clamping rod 323 extends downward from the mating end to the clamping end, and the mating ends of the two groups of clamping rods 323 are in contact with the abutment block 315; in the stationary state of the nose clamping component, the mating ends of the two groups of clamping rods 323 are close to each other and the clamping ends are far away; in the action state of the nose clamping component, the abutment block 315 abuts against the two groups of clamping rods 323 to rotate inward, so that the clamping ends of the clamping rods 323 clamp the nose.

[0026] The two V-shaped clamping rods 323 are designed to be compatible with the abutment block 315, and this structural design has a fast response speed; the open ends of the two sets of clamping rods 323 are placed on both sides of the nose, and when the abutment block 315 moves, it can quickly abut the close ends of the two sets of clamping rods 323, so that the clamping rods 323 and the pendulum 322 rotate, and the clamping ends of the two sets of clamping rods 323 rotate inward to abut the nose to close, thereby realizing a fast response closure of the nose; Furthermore, the clamping rod 323 is designed to be inclined, with the mating end at a high position and the clamping end at a low position. This inclined design can adapt to the side slope contour of the nose, so that the clamping rod 323 can be accurately and quickly placed on both sides of the nose tip at the beginning; at the same time, the inclined clamping rod 323 can reduce the contact area between the clamping rod 323 and the nose, thereby reducing interference during clamping, so that the clamping end of the clamping rod 323 can accurately squeeze and contact the nose.

[0027] In order to enable the extrusion assembly 4 to automatically and accurately extrude the breathing airbag 1, the breathing airbag 1 is placed vertically above the face for use.

The two groups of moving blocks 42 are respectively mounted on the two ends of the bidirectional screw 43, and the outer end of the moving block 42 is provided with an extrusion vertical plate 44; the bottom surface of the guide back plate 41 is vertically symmetrically provided with a support rod 45 extending downward, and the support rod 45 is docked with the stretcher assembly 5.

[0028] When the face mask 2 is fixed, the breathing airbag 1 is placed vertically above the face. In this way, it does not occupy the rest of the area, which is convenient for subsequent patient transfer and docking with the extrusion assembly 4; The balloon 11 is initially placed between two sets of extrusion vertical plates 44. The bidirectional screw 43 can drive two sets of moving blocks 42 to approach each other, thereby driving the extrusion vertical plates 44 to move inward. The extrusion vertical plates 44 move inward to squeeze the balloon 11; A first motor 431 for driving the bidirectional screw 43 to rotate is externally provided on the guiding back plate 41; By adjusting the working parameters of the first motor, the rotation speed of the bidirectional screw can be adjusted, and then the frequency of squeezing the balloon and the individual extrusion depth can be adjusted to meet the oxygen requirements in different rescue stages.

[0029] Two sets of support rods 45 can be inserted into the stretcher assembly 5, so as to stably support the movement of the extrusion vertical plates 44.

[0030] After the above-mentioned face mask 2 and breathing airbag 1 are arranged, the problems to be solved in first aid are to perform cardiopulmonary resuscitation manually and quickly arrange a stretcher to transfer the patient; To solve the above problems, the following solutions are given: The stretcher assembly 5 includes a head support plate 51, a neck support plate 52, a cross plate 53 and a chest support plate 54. The head support plate 51 is provided on the outer side wall of the neck support plate 52. An air cushion 521 is provided on the surface of the neck support plate 52. A cross plate 53 is vertically provided in the middle of the inner side wall of the neck support plate 52. The end of the cross plate 53 is provided with a chest support plate 54.

[0031] In the above solutions: 1. Designing an integrated head support plate 51, neck support plate 52, cross plate 53 and chest support plate 54 can support the upper body of the patient. The overall size is small, and it is convenient to carry in first aid. When arranging, only need to lift the upper body of the patient, place the integrated head support plate 51, neck support plate 52, cross plate 53 and chest support plate 54 on the ground, and then the patient can lie on each plate body; 2.

When the neck support plate 52 is in place, the shoulder positioning member 6 will also be in place. At this time, the shoulder positioning member 6 stops against the patient's shoulders, achieving the stop constraint on the shoulders; thereby suppressing the tendency of the human body to tilt upward during artificial chest compression and avoiding the influence of human body shaking on the compression effect. 4. The inverted U-shaped integrated reinforcing longitudinal plate 55 and side splints 56 are designed. When not in use, they are separated from the chest support plate 54. After the chest support plate 54 is arranged, the side splints 56 are inserted on both sides of the surface of the chest support plate 54, and the bottom ends of the side splints 56 are positioned by elastic chucks or by locking bolts. 5. The shoulder positioning member 6 is integrated with the reinforcing longitudinal plate 55 through the belt body 65 and the clamping plate 71. When the clamping plate 71 is inserted into the locking tube 551, the elastic claw 552 clamps and positions the clamping plate 71; at this time, the belt body 65, the reinforcing longitudinal plate 55, the side splints 56, the chest support plate 54, the cross plate 53, and the shoulder positioning member 6 form a stable trapezoidal constraint structure outside the human body, ensuring the stability of the human body during cardiopulmonary resuscitation and transportation.
