DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Reference Figure 1 , first aid equipment, relates to the technical field of medical devices, and mainly comprises a first aid box 1, which is used to store various items and equipment required for first aid. On one side of the first aid box 1, a rotating shaft 2 is rotatably connected to the base, and a closed cover 3 is fixedly sleeved on the outer wall of the rotating shaft 2. The closed cover 3 can be opened or closed by rotating the rotating shaft 2. In order to facilitate opening the closed cover 3, a U-shaped handle 4 is also rotatably connected to the top of the closed cover 3, which is convenient for the user to hold and rotate the closed cover 3.

[0047] Reference Figure 2Inside the first aid kit 1, a defibrillator 15 is provided for defibrillation treatment of the patient in an emergency. In addition, two clamping plates 13 are fixed on one side of the first aid kit 1 for cooperating with the structure on the closing cover 3 to achieve a stable closing effect. A liquid storage tank 16 and a humidifying cylinder 28 are fixed on the bottom inner wall of the first aid kit 1. The liquid storage tank 16 contains hydrogen peroxide, and the humidifying cylinder 28 contains distilled water. The humidifying cylinder 28 is designed to soak the oxygen injected from the liquid storage tank 16 to make it more suitable for the patient to inhale.

[0048] Reference Figure 4 In addition, a liquid inlet and a liquid outlet pipe 18 are designed for the liquid storage tank 16. The liquid inlet is used to inject hydrogen peroxide into the liquid storage tank 16, and a first rubber plug 17 is threadedly connected to the liquid inlet to close the liquid inlet. The liquid outlet pipe 18 is fixedly connected to one side of the liquid storage tank 16, and one end thereof extends to one side of the first aid kit 1. A first valve 19 is provided on the liquid outlet pipe 18. By controlling the switch of the first valve 19, the hydrogen peroxide in the liquid storage tank 16 can be discharged for disinfection and sterilization of the wound.

[0049] Reference Figure 1 , Figure 2 and Fig. 9 In order to realize the closing and opening of the first aid box 1 by the closing cover 3, a set of closing structures is designed. This set of closing structures includes a fixed column 7 fixed to one side of the closing cover 3 through a base, and the outer wall of the fixed column 7 is slidably sleeved with two L-shaped plates 8. The two L-shaped plates 8 are located between two clamping plates 13 and cooperate with the clamping plates 13 to achieve a clamping effect. A first spring 9 is fixed to the side where the two L-shaped plates 8 are close to each other. The first spring 9 is sleeved on the outer wall of the fixed column 7 to provide an outward elastic force for the L-shaped plate 8 so that it can be closely matched with the clamping plate 13. A fixing pin 10 is fixed to the top of the two L-shaped plates 8. A sliding groove 5 is provided at the top of the closing cover 3, and a sliding column 6 is slidably connected in the sliding groove 5. A limiting groove 12 is provided on the outer wall of the sliding column 6, and a pull rope 11 is sleeved in the limiting groove 12. The two ends of the pull rope 11 are fixedly connected to the two fixing pins 10 respectively. Through the cooperation between the sliding column 6 and the pull rope 11 , the user can easily pull the two L-shaped plates 8 toward the middle, thereby releasing the clamping of the clamping plate 13 and the L-shaped plates 8 and realizing the opening of the closing cover 3 .

[0050] The user can use the thumb to push the sliding column 6 to move inward, and the sliding column 6 drives the two L-shaped plates 8 to move toward the middle through the pull rope 11 and squeezes the first spring 9, so that the L-shaped plate 8 is released from the card plate 13, and then the closing cover 3 can be flipped to release the closure of the first aid box 1.

[0051] Reference Figure 2-Figure 5In order to generate oxygen from hydrogen peroxide, an oxygen supply structure is designed. This oxygen supply structure includes a discharge barrel 20 fixed on the top of the liquid storage tank 16, and the bottom end of the discharge barrel 20 is fixedly extended into the liquid storage tank 16. A feed port is provided at the top of the discharge barrel 20, and a second rubber plug 21 is threadedly connected to the feed port to close the feed port to prevent hydrogen peroxide from leaking out. In the discharge barrel 20, a rotating shaft 22 is rotatably connected, and a rotating plate 23 is fixedly sleeved on the outer wall of the rotating shaft 22, and the rotating plate 23 is used to close the discharge barrel 20. A catalyst can be placed on the top of the rotating plate 23. One end of the rotating shaft 22 rotates and extends to one side of the discharge barrel 20, and a gear 24 is fixed thereto. On one side of the discharge barrel 20, a rack 25 meshing with the gear 24 is slidably connected. A second spring 26 is fixed to the bottom end of the rack 25, and the bottom end of the second spring 26 is fixed to the top of the liquid storage tank 16. The thrust of the second spring 26 on the rack 25 can drive the gear 24 and the rotating plate 23 to rotate.

[0052] Specifically, when it is necessary to generate oxygen, the rack 25 can be released from the suppression, so that the rack 25 moves up under the action of the second spring 26, and cooperates with the gear 24 to drive the rotating plate 23 to rotate, thereby pouring the catalyst contained on the rotating plate 23 into the liquid storage tank 16. Under the action of the conical platform 27, the catalyst will be scattered into the liquid storage tank 16 and fully contact with the hydrogen peroxide, thereby generating oxygen. An air guide 29 is also fixed on the top of the liquid storage tank 16, and the air guide 29 is connected to the liquid storage tank 16. The outer wall of the air guide 29 is provided with a flow control valve 30 for controlling the flow of oxygen. One end of the air guide 29 away from the liquid storage tank 16 is fixedly extended into the humidification cylinder 28, and the oxygen generated in the liquid storage tank 16 is injected into the humidification cylinder 28. A first air guide hose 31 is fixed to the top of the humidification tube 28. The first air guide hose 31 is connected to the humidification tube 28. An oxygen mask 32 is fixed to the end of the first air guide hose 31 away from the humidification tube 28 for supplying humidified oxygen to the patient.

[0053] Reference Figure 3 An air bag 34 is designed and placed on the bottom inner wall of the first aid kit 1. In order to inject oxygen into the air bag 34, the following measures are taken: a second air guide hose 33 is fixedly connected to the top of one side of the liquid storage tank 16, and the other end of the second air guide hose 33 is connected to the air bag 34. In order to ensure the controllable injection of oxygen, a second valve 35 is set on the second air guide hose 33.

[0054] Specifically, when oxygen needs to be injected into the airbag 34, the second valve 35 can be opened, and then the oxygen generated by the chemical reaction in the liquid storage tank 16 (such as the decomposition of hydrogen peroxide under the action of a catalyst) will be injected into the airbag 34 through the second air guide hose 33, so that the airbag 34 expands. The expanded airbag 34 can be placed on the patient's chest by medical personnel, and when performing compression-type cardiopulmonary resuscitation, the airbag 34 can play a role of buffering and protection, preventing medical personnel from causing damage to the patient's chest due to excessive pressure.

[0055] Reference Figure 5 and Figure 6 In order to realize the opening and control of the oxygen supply structure, a set of control structures is designed. This set of control structures is arranged in the closed cover 3 and cooperates with the closed cover 3. When the closed cover 3 is opened, it can synchronously drive the pressing plate 37 to rotate, thereby releasing the pressing of the rack 25. In this way, the rack 25 can move up under the action of the second spring 26, cooperate with the gear 24 to drive the rotating plate 23 to rotate, and start to generate oxygen. The control structure includes a notch 36 arranged inside the closed cover 3, and a pressing plate 37 is installed in the notch 36. The pressing plate 37 cooperates with the rack 25 and is used to press the rack 25 when necessary to prevent it from moving. The pressing plate 37 is rotatably sleeved on the outer wall of the rotating shaft 2, so that the pressing plate 37 can rotate with the rotating shaft 2. On one side of the first aid box 1, a fixed platform 38 is fixed, and this fixed platform 38 is also rotatably sleeved on the outer wall of the rotating shaft 2. On both sides of the fixed platform 38, a torsion spring 39 is fixed. The two torsion springs 39 are fixedly connected to the pressing plate 37 at the sides away from each other, and the torsion springs 39 are also sleeved on the outer wall of the rotating shaft 2. It should be noted that the torsion force of the torsion spring 39 is greater than the elastic force of the second spring 26, so that the pressing plate 37 can reliably press the rack 25 when needed.

[0056] Reference Figure 5-Figure 8 At the top of the closing cover 3, an extrusion groove 40 is designed, and two fixing rods 41 are fixed in this extrusion groove 40. A lever 42 is slidably connected to the outer wall of the two fixing rods 41. Two third springs 43 are fixed to the side of the lever 42 close to the clamping plate 13, and the two third springs 43 are fixed in the extrusion groove 40, and they are also sleeved on the outer wall of the fixing rod 41. The function of the two third springs 43 is to drive the lever 42 to return to the inside. A movable cavity 47 connected to the extrusion groove 40 is also designed in the closing cover 3. In this movable cavity 47, an L-shaped rod 44 is slidably connected. One end of the L-shaped rod 44 is fixedly connected to the lever 42, and the other end is used to engage with the bayonet 46 on the pressing plate 37.

[0057] Specifically, when the lever 42 is pulled outward, the L-shaped rod 44 will also move accordingly, thereby releasing the engagement with the bayonet 46, and the closing cover 3 and the pressing plate 37 can rotate separately. Conversely, when the lever 42 is reset, the L-shaped rod 44 will reengage with the bayonet 46, thereby forming the closing cover 3 and the pressing plate 37 as a whole.

[0058] Reference Figure 8 In order to make the L-shaped rod 44 insert into the bayonet 46 more smoothly when the closing cover 3 is reset, a slope 45 is designed at one end of the L-shaped rod 44 close to the pressing plate 37. This slope 45 cooperates with one side of the top of the pressing plate 37 to play a guiding role when the closing cover 3 is reset.

[0059] Reference Figure 4 , Figure 5 and Fig. 9 A card slot 14 is designed and arranged on one side of the L-shaped plate 8 close to the adjacent card plate 13. The card slot 14 can be snap-fitted with the card plate 13. Such a design can greatly increase the stability of the connection between the card plate 13 and the L-shaped plate 8. At the same time, a conical platform 27 is fixed on the top inner wall of the liquid storage tank 16 through a connecting rod. The position of the conical platform 27 is designed to be directly below the discharge barrel 20, and the outer diameter of the conical platform 27 is larger than the inner diameter of the discharge barrel 20. Such a design can ensure that the catalyst dropped from the discharge barrel 20 can be dispersedly placed in the liquid storage tank 16, so that the catalyst can be more fully in contact with hydrogen peroxide, thereby accelerating the decomposition of hydrogen peroxide and generating more oxygen.

[0060] In the present application, the catalyst placed on the rotating plate 23 is manganese dioxide.

[0061] Example 2: Reference Fig.10 and Fig.11 , improved on the basis of Example 1: a display screen 52 is fixed at the bottom of the closing cover 3. A medicine box 53 is placed at the bottom of the first aid box 1. In order to ensure the stability of the medicine box 53 in the first aid box 1, a plurality of positioning pins 54 are fixed at the bottom of the medicine box 53, and a plurality of pin holes matching these positioning pins 54 are set on the bottom inner wall of the first aid box 1. A through hole 48 is designed and set on the side of the first aid box 1 close to the card plate 13. An L-shaped placement plate 49 is slidably connected in the through hole 48. The L-shaped placement plate 49 can be used to close the medicine box 53. In order to ensure that the L-shaped placement plate 49 can stay stably in the through hole 48, a magnetic stopper 50 is fixed in the through hole 48. The magnetic stopper 50 can brake the L-shaped placement plate 49. A plurality of ECG electrodes 51 are placed on the top of one side of the L-shaped placement plate 49, and electrical connection is achieved between these ECG electrodes 51 and the display screen 52.

[0062] In actual use, medical personnel can pull the L-shaped placement plate 49 outward to release the seal of the medicine box 53, so as to facilitate drug treatment for the patient. At the same time, the ECG electrodes 51 will also be removed from the first aid kit 1 as the L-shaped placement plate 49 is pulled out, and medical personnel can stick these ECG electrodes 51 on the patient's temple to detect the patient's heart rate, and display the patient's electrocardiogram on the display screen 52, providing important reference information for medical personnel's treatment work.

[0063] A method for using a portable cardiovascular emergency device comprises the following steps:

[0064] S1. When in use, the first aid kit 1 can be lifted up by the U-shaped handle 4 and quickly moved to the side of the patient to be treated. The thumb pushes the sliding column 6 to move inward, and the other fingers pull the lever 42 outward. At this time, the sliding column 6 drives the two L-shaped plates 8 to move toward the middle through the pull rope 11 and squeezes the first spring 9. The L-shaped plate 8 is released from the clamping plate 13, and the closing cover 3 can be turned over. When the lever 42 moves, it drives the L-shaped rod 44 to move out of the clamping hole 46, and the brake between the closing cover 3 and the pressing plate 37 is released. Therefore, when the closing cover 3 is turned over, the pressing plate 37 is in a stationary state under the action of the torsion spring 39, and the pressing plate 37 continues to press the rack 25. At this time, the medical staff can perform cardiopulmonary resuscitation on the patient through the defibrillator 15 and the defibrillation ECG electrode 51;

[0065] S2. When the patient has other wounds on his body, the first valve 19 is opened to discharge the hydrogen peroxide in the liquid storage tank 16 through the liquid outlet pipe 18, and the wound is cleaned with hydrogen peroxide to prevent bacterial infection of the wound;

[0066] S3. When the patient is in urgent need of oxygen supply, the closing cover 3 closes the first aid kit 1 again, and during the closing process, the L-shaped rod 44 is re-engaged in the bayonet 46 under the action of the inclined surface 45. At this time, the closing cover 3 and the pressing plate 37 form a whole. When the closing cover 3 is turned over and rotated again, the pressing plate 37 is synchronously driven to rotate. The pressing plate 37 releases the pressing of the rack 25. The rack 25 moves upward under the action of the second spring 26. The rack 25 cooperates with the gear 24 to drive the rotating plate 23 to rotate. The catalyst contained on the rotating plate 23 is poured into the liquid storage tank 16, and the catalyst is scattered into the liquid storage tank 16 under the action of the conical platform 27, so that the catalyst can fully contact the hydrogen peroxide. The hydrogen peroxide generates oxygen under the action of the catalyst. The flow rate of oxygen entering the humidification cylinder 28 is adjusted by the flow control valve 30, and the oxygen entering the humidification cylinder 28 is soaked by the distilled water in the humidification cylinder 28, so that it is convenient for the patient to absorb it through the oxygen mask 32;

[0067] S4. When chest compression cardiopulmonary resuscitation is required, the second valve 35 is opened, and the oxygen generated in the liquid storage tank 16 is injected into the airbag 34 through the second air guide hose 33. The airbag 34 expands, and the medical staff places the expanded airbag 34 on the patient's chest to protect the patient during the subsequent compression cardiopulmonary resuscitation process to avoid excessive pressure causing damage to the patient's chest;

[0068] S5. In addition, by pulling the L-shaped placement plate 49 outward, the medicine box 53 is released, which makes it easier for medical personnel to provide drug treatment to the patient. At the same time, the ECG electrode 51 is removed from the first aid kit 1. Medical personnel can detect the patient's heart rate by sticking the ECG electrode 51 on the patient's temple and display the patient's electrocardiogram on the display screen 52.

[0069] However, as is well known to those skilled in the art, the working principles and wiring methods of the ECG electrodes 51, flow control valve 30 and defibrillator 15 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
