Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly relates to a combined first-aid device for ECMO and CPR. Background Art
[0002] In the field of modern medical first aid, cardiopulmonary resuscitation (CPR) and extracorporeal membrane oxygenation (ECMO) are two crucial first-aid measures. They are respectively targeted at different cardiopulmonary failure situations, with their own unique rescue paths and timeliness requirements.
[0003] CPR is an emergency rescue measure aimed at restoring cardiac and respiratory functions by pressing the chest cavity and performing artificial respiration, thereby saving lives. It is mainly applicable to patients in the initial stage of cardiac arrest or respiratory failure and with relatively low degrees of cardiopulmonary attenuation. Successful CPR can greatly improve the survival rate of patients and the possibility of neurological function recovery. However, CPR also has limitations. It can only address mild to moderate cardiopulmonary failure situations, and for patients with more severe cardiopulmonary failure, relying solely on CPR often fails to work effectively.
[0004] ECMO is an advanced life support technology. It establishes an artificial blood circulation and oxygenation system outside the body to temporarily replace the damaged cardiopulmonary functions of patients and provide stable blood circulation and oxygenation support for patients. ECMO is mainly applicable to patients with severely damaged cardiopulmonary functions and already in a state of severe hypoxia.
[0005] The rescue process of ECMO is relatively complex and requires a professional medical team to operate. First, vascular catheters need to be inserted into the patient's body to provide a passage for ECMO; then, the ECMO device is started, and the patient's blood is drawn out of the body for oxygenation and circulation; finally, the oxygenated blood is reinfused into the patient's body to achieve the purpose of supporting cardiopulmonary functions.
[0006] However, the startup and operation of ECMO require a certain amount of time. From catheterization operation to the effective operation of the machine, it usually takes from several minutes to dozens of minutes. This is undoubtedly a huge challenge for patients already in a state of severe hypoxia. Because during this waiting period, patients may suffer further damage due to continuous hypoxia, and even lead to irreversible organ failure.
[0007] CPR can be carried out quickly to restore partial blood circulation and respiratory functions in a timely manner, but the duration is limited and it cannot play a fundamental role for patients with cardiopulmonary attenuation; ECMO can completely replace cardiopulmonary functions to provide continuous and stable life support for patients, but it requires a certain startup and operation time, and for patients with severely damaged cardiopulmonary functions and already in a state of severe hypoxia, it may not be able to support them through the waiting time. Summary of the Invention
[0008] The present invention is intended to provide ECMO and CPR combined emergency rescue equipment to solve the technical problem in the prior art that the startup and operation of ECMO requires a certain amount of time, and during this period the patient may suffer further damage due to continued hypoxia.
[0009] To achieve the above-mentioned object, the present invention adopts the following technical scheme: an ECMO and CPR combined emergency equipment, comprising: an internal tube wound fixation component, an ECMO device that provides extracorporeal respiration and circulation for the patient through the internal tube, and a CPR device that provides cardiopulmonary resuscitation for the patient when the ECMO device does not work effectively;
[0010] The internal tube fixing assembly comprises a base fixing ring and a snap-fit fixing cover; the base fixing ring is provided with a suture hole for suturing and fixing with the skin and an external threaded hole extending outward; the external threaded hole is for the internal tube to pass through, and the tube body of the internal tube fits with the inner hole wall of the external threaded hole; one side of the snap-fit fixing cover is provided with an internal threaded hole for the internal tube to pass through, and the other side of the snap-fit fixing cover is provided with a winding groove for fixing the outer section of the internal tube; the snap-fit fixing cover and the base fixing ring are threadedly fixed through the internal threaded hole and the external threaded hole.
[0011] The principle and advantages of this scheme are: it combines ECMO equipment, CPR equipment and internal tube wound fixation components; in actual application, when the patient is detected to have severe cardiac arrest or cardiopulmonary failure, a preliminary assessment is immediately performed and cardiopulmonary resuscitation is started to maintain the patient's blood circulation and oxygen supply. If the patient's condition does not improve significantly after CPR and meets the medical indications for ECMO catheterization, ECMO catheterization is prepared. During the catheterization process, CPR needs to be temporarily stopped, but the patient's vital signs should be closely monitored. After the catheterization is completed, the internal tube at the intubation wound is properly fixed with the internal tube fixation component to prevent displacement or detachment. Slowly start the ECMO device and start extracorporeal respiratory and circulatory support. At the same time, closely monitor the patient's vital signs, ECMO device parameters and possible complications. Before the ECMO device is fully functional, it may be necessary to continue CPR on the patient until ECMO completely takes over the cardiopulmonary function. Once ECMO is effective and the patient's vital signs are stable, the use of CPR can be gradually reduced until it is completely stopped.
[0012] Among them, the fixing process of the built-in tube wound fixing component is to pre-pass the blood vessel built-in tube through the internal threaded hole and the external threaded hole before the tube placement operation. After the tube placement is completed, the basic suture at the wound is completed so that the skin around the wound fits the outer wall of the built-in tube. Move the base fixing ring along the built-in tube to the intubation wound to ensure that it fits the skin tightly, and then use sutures to suture the suture holes on the fixing ring to the skin to ensure that the base fixing ring is firmly fixed on the skin. Subsequently, the buckle fixing cover is rotated onto the base fixing ring until the two are tightly connected. During the whole process, ensure that the built-in tube passes through the internal threaded hole smoothly, and the posture of the in vitro built-in tube section close to the skin end is fixed by the nesting of the external threaded hole and the internal threaded hole. Finally, the in vitro built-in tube section close to the end of the buckle fixing cover is embedded in the coiling groove.
[0013] By combining ECMO and CPR, effective extracorporeal respiratory and circulatory support can be quickly provided when the patient suffers cardiac arrest or cardiopulmonary failure, while maintaining the patient's blood circulation and oxygen supply, thereby improving the efficiency of emergency treatment. The internal tube fixing component adopts a threaded fixation and coiled groove design, which effectively avoids the problem of fixation failure caused by skin sweating or secretion. Compared with the traditional adhesive fixation method, this component can fix the internal tube more firmly, reduce the external traction force on the internal tube at the wound, and reduce the risk of the tube falling off.
[0014] Before the ECMO device is fully functional, the patient may suffer further damage due to continued hypoxia. This solution reduces the patient's damage by continuing to use CPR and the internal tube fixation method to ensure the patient's oxygen supply and life safety while waiting for the ECMO to function. The design of the internal tube fixation component makes the tube placement operation simpler and faster, reduces the operation time and complexity, and improves the efficiency of emergency treatment.
[0015] Preferably, as an improvement, the suture holes are three and are symmetrically distributed centrally, and the external threaded hole is located at the center of the three suture holes; the outer edge of each suture hole is an arc contour, and adjacent suture holes are connected by a smooth arc inner edge, and the distance from the center of the suture hole to the nearest edge of the base fixing ring is the radius of the arc outer contour of the suture hole.
[0016] The beneficial effect of this improvement is that by designing the suture holes to be distributed in three symmetrical centers and optimizing their arc contours and the distance from the edge of the base fixing ring, it is ensured that after the suture thread passes through the skin and the suture hole, when it is inserted into the skin again outside the suture hole to form a entanglement, all suture thread segments are evenly distributed along the arc outer contour of the suture hole with the shortest distance. This design not only reduces the number of suture points, but also greatly improves the stability of the base fixing ring relative to the skin.
[0017] Since every contact point of the suture on the base fixing ring follows the same shortest path principle, once the suture is completed, the base fixing ring is firmly "locked" in the predetermined position. This design almost eliminates any minor movement that may cause unstable fixation, thereby further improving the reliability and safety of the internal tube fixation.
[0018] Preferably, as an improvement, the snap-fit fixing cover is a disc-shaped cover body, the snap-fit fixing cover completely covers the suture between the base fixing ring and the skin, and a transparent silicone pad is provided on the outer periphery of the snap-fit fixing cover and the skin contact surface.
[0019] The beneficial effect of this improvement is that the transparent silicone pad, as an isolation layer between the buckle fixing cover and the skin, can effectively prevent external bacteria, dust and other pollutants from entering the wound, thereby reducing the risk of infection. The silicone material is soft and skin-friendly, which can reduce the foreign body sensation that may be caused when the buckle fixing cover fits tightly against the skin, thereby improving the patient's comfort. The contact between the transparent silicone pad and the skin and its elastic properties enable it to share the connection pulling force at the intubation wound and suture to a certain extent, while also reducing the pressure and friction on the skin.
[0020] Preferably, as an improvement, the winding groove is in a spiral shape, extending spirally outward from the central internal thread opening of the buckled fixing cover.
[0021] The beneficial effects of this improvement are: the design of the spiral winding groove enables the built-in tube to be neatly fixed and wound along a specific path; the spiral design enables the built-in tube to form natural tension during the winding process, and this tension helps to firmly fix the built-in tube in the winding groove, reducing the risk of falling off. The spiral winding groove can make full use of the space of the buckled fixing cover, making the built-in tube more compact and orderly when fixed.
[0022] Preferably, as an improvement, the ECMO device comprises an oxygenator, a main unit and a filter, the main unit comprises a shell, the interior of the shell is provided with a motor, a power plug, a battery compartment, and a pump detachably connected to the motor, the bottom of the shell is fixedly connected to a water tank, the front of the shell is provided with a panel assembly, the shell is connected to a hook assembly, and the oxygenator and the filter are detachably connected to the shell through a connecting assembly.
[0023] The beneficial effect of this improvement is that the modular design of ECMO equipment makes it easy to disassemble, replace and maintain each component, reducing maintenance costs and increasing the service life of the equipment. Users can choose different models of oxygenators, filters and other components according to actual needs to achieve flexible configuration and meet the treatment needs of different patients.

[0026] The beneficial effects of this improvement are: the U-shaped clip design enables the oxygenator and filter to be quickly and firmly fixed on the mounting base, improving the installation efficiency. The design of the clamping part ensures the stability of the oxygenator and filter during use, avoiding safety hazards caused by shaking or falling off. The clamping design facilitates the user to clean and maintain the oxygenator and filter, extending the service life of the equipment.
[0027] Preferably, as an improvement, the first mounting seat also includes a first socket base detachably connected to the shell and a first connecting plate plugged into the first socket base, and the first clip is detachably connected to the first connecting plate; the second mounting seat also includes a second socket base detachably connected to the shell and a second connecting plate plugged into the second socket base, and the second clip is detachably connected to the second connecting plate.
[0028] The beneficial effect of this improvement is that the socket and detachable design allows users to adjust the position and number of the mounting base according to actual needs, improving the flexibility and scalability of the equipment. When the mounting base or the clip fails, the user can quickly disassemble and replace the new component, reducing the difficulty and time cost of maintenance.

[0030] The beneficial effects of this improvement are: the integration of AED and electric telescopic rod realizes intelligent first aid, which can automatically identify the patient's ECG activity and take corresponding first aid measures, thereby improving the success rate of first aid. The automatic pressing function of the electric telescopic rod reduces the physical burden of first aid personnel and improves the efficiency and quality of first aid.

[0048] Example
[0049] An ECMO and CPR combined emergency equipment includes: an internal tube wound fixation component, an ECMO device that provides extracorporeal respiration and circulation for patients through an internal tube, and a CPR device that provides cardiopulmonary resuscitation for patients when the ECMO device does not work effectively.
[0050] Among them, as attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the built-in tube fixing assembly includes a base fixing ring 1 and a snap-fit fixing cover 4.
[0051] The base fixing ring 1 is provided with suture holes 3 for suturing and fixing with the skin and external threaded holes 2 extending outward. There are three suture holes 3 distributed symmetrically with the center, and the external threaded hole 2 is located at the center of the three suture holes 3. The external threaded hole 2 is for the built-in tube to pass through, and the tube body of the built-in tube fits with the inner hole wall of the external threaded hole 2. The outer edge of each suture hole 3 is an arc contour, and adjacent suture holes 3 are connected by smooth arc inner edges. The distance from the center of the suture hole 3 to the nearest edge of the base fixing ring 1 is the arc outer contour radius of the suture hole 3.
[0052] When the suture thread passes through the skin and the suture hole 3, and is inserted into the skin again outside the suture hole 3 to form a winding, all suture thread segments are distributed along the arc outer contour of the suture hole 3, and the path length of the suture thread on the base fixing ring 1 remains consistent and is the shortest. This uniform and shortest distance winding method effectively limits the small range of movement of the base fixing ring 1 relative to the skin. Since each contact point of the suture thread on the base fixing ring 1 follows the same shortest path principle, once the suturing is completed, the base fixing ring 1 is firmly "locked" in the predetermined position, almost eliminating any slight movement that may cause unstable fixation.
[0053] One side of the buckle fixing cover 4 is provided with an internal thread hole 5 for the built-in tube to pass through, and the other side of the buckle fixing cover 4 is provided with a winding groove 6 for fixing the outer section of the built-in tube. The buckle fixing cover 4 and the base fixing ring 1 are threadedly fixed through the internal thread hole 5 and the external thread hole 2, and the outer section of the built-in tube passes through the external thread hole 2 and the internal thread hole 5 to the free side of the buckle fixing cover 4.
[0054] The buckled fixing cover 4 is a disc-shaped cover body, which completely covers the suture between the base fixing ring 1 and the skin. The outer periphery of the buckled fixing cover 4 and the skin contact surface are provided with a transparent silicone pad 7, which effectively prevents external contamination of the wound and reduces the foreign body sensation that may be generated when the buckled fixing cover 4 is tightly attached to the skin.
[0055] The winding groove 6 is in a spiral shape, extending outward in a spiral circumferential direction from the central internal thread opening of the buckle-fitting cover 4. The free section of the internal tube on the outside of the buckle-fitting cover 4 is inserted into the winding groove 6 for clamping and fixing, and the internal tube on the inside of the buckle-fitting cover 4 is fixed perpendicular to the patient's skin, so that the external section of the internal tube is firmly fixed, avoiding skin traction wrinkles at the insertion site and swinging of the internal tube caused by the patient's limb movement.
[0056] Compared with the traditional adhesive fixing method, the present invention effectively avoids the problem of fixation failure caused by skin sweating or secretion.
[0057] Before ECMO has taken effect, patients who have completed the intubation can also receive CPR. At this time, the fixing method provided by the present invention can ensure the stability of the intubation site and avoid adverse effects on the intravascular catheter due to external traction.
[0058] Before the catheterization operation, the vascular catheter is passed through the internal threaded hole 5 and the external threaded hole 2 in advance. After the catheterization is completed, the basic suture at the wound is completed so that the skin around the wound fits the outer wall of the built-in tube. Move the base fixing ring 1 along the built-in tube to the intubation wound to ensure that it fits the skin tightly, and then use sutures to suture the suture holes 3 on the fixing ring with the skin to ensure that the base fixing ring 1 is firmly fixed on the skin. Subsequently, the buckle fixing cover 4 is rotated onto the base fixing ring 1 until the two are tightly connected. During the whole process, ensure that the built-in tube passes through the internal threaded hole 5 smoothly, and the posture of the in vitro built-in tube section near the skin end is fixed by the nesting of the external threaded hole 2 and the internal threaded hole 5. Finally, the in vitro built-in tube section near the end of the buckle fixing cover 4 is embedded in the winding groove 6 along the spiral. Thereby reducing the force of external traction on the built-in tube at the wound.
[0059] Among them, the structure of the ECMO device that provides continuous extracorporeal respiration and circulation to maintain the patient's life through an intravascular catheter is as follows:
[0060] As attached Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, it includes an oxygenator 8, a main unit 9 and a filter 10. The main unit 9 includes a housing 11.

The housing 11 includes a bottom shell 22 and an upper cover plate 23. The upper cover plate 23 is connected to the top of the bottom shell 22 by bolts.
[0061] The connection assembly includes a first mounting seat for detachably connecting the oxygenator 8 and a second mounting seat for detachably connecting the filter 10.

Specifically, when connecting, the first clamping piece 14 is bolted to the first connecting plate 17, and the second clamping piece 15 is bolted to the second connecting plate 19.
[0063] The hook 21 assembly includes a hanging rod 20 and a hook 21 fixedly connected to the hanging rod 20, and the hook 21 can be used to hang liquid drugs such as normal saline.
[0064] The panel assembly 13 includes a display panel 24, a screen conversion board 25 and an adjustment knob 26, and the display panel 24 is bolted to the screen conversion board 25. In order to facilitate medical staff to observe the data on the display panel 24 during the operation, the panel assembly 13 is inclinedly installed on the housing 11, and the inclination angle relative to the plane is 52° - 58°. Specifically, in this embodiment, the inclination angle is 55°. Since the display panel 24 needs to be recessed inward by a certain distance during installation, in order to protect the adjustment knob 26, the height of the adjustment knob 26 is the same as the distance that the display panel 24 is recessed inward. Specifically, in this embodiment, the height of the adjustment knob 26 is 12 mm.
[0065] In order to prevent the electromagnetic waves generated by the motor during operation from interfering with the circuits in the housing 11, the ECMO device further includes a motor cover. Specifically, when connecting, the pump is connected to the housing 11 by countersunk head screws, the motor is bolted to the pump, and the motor cover covers the pump and the motor and is then bolted to the housing 11.
[0066] The power plug includes a plug fixing seat, a plug fixed end and a plug insertion and extraction end matching the plug fixed end. The plug fixing seat is arranged on the housing 11, and the plug fixed end is fixedly arranged in the plug fixing seat, so that the plug insertion and extraction end can quickly align with the plug fixed end, facilitating the connection of the power plug to the power supply. A handle 27 is provided on the upper cover plate 23.

Then the staff can use the AED 30-1 starts the electric telescopic rod 30-2 to descend. When the electric telescopic rod 30-2 descends, the compression pad 30-3 can be driven to descend, so that the compression pad 30-3 can contact the patient's chest cavity, and then CPR can be performed. When defibrillation of the patient is required, there is no need to take the defibrillator. The staff can pull the connecting line 30-4 to place the electrode plate 30-5 on the patient's body, and use the AED 30-1 to control the electrode plate 30-5 to defibrillate the patient.

[0072] Step 1: When a patient is detected to have severe cardiac arrest or cardiopulmonary failure, conduct a preliminary assessment immediately. Without delay, start cardiopulmonary resuscitation immediately to initially restore the patient's heart function. The CPR device maintains the patient's blood circulation and oxygen supply through chest compressions and artificial respiration.
[0073] Step 2: While continuing CPR, closely monitor the patient's vital signs and reactions. If the patient's condition does not improve significantly after CPR and meets the medical indications for ECMO cannulation (such as refractory cardiac arrest, severe cardiopulmonary failure, etc.), prepare for ECMO cannulation.
[0074] Step 3: Ensure that the ECMO equipment is ready, including checking the machine status, pipeline connections, anticoagulants, etc. Under the operation of the medical team, the patient is cannulated by ECMO, usually involving puncture and cannulation of the femoral vein and / or internal jugular vein. During the cannulation process, CPR needs to be temporarily stopped to ensure the safety and accuracy of the cannulation. However, the patient's vital signs should be closely monitored and prepared to resume CPR at any time.
[0075] Step 4: After the catheter is placed, use the catheter fixing assembly to fix the catheter at the intubation site to prevent displacement or falling off. Slowly start the ECMO device to start extracorporeal respiratory and circulatory support. At this point, ECMO will take over part or all of the cardiopulmonary function and provide the patient with the necessary oxygen and nutrients.
[0076] Step 5: Closely monitor the patient's vital signs, ECMO device parameters, and any possible complications. Since the ECMO device takes a certain amount of time to effectively restore the patient's blood oxygenation, CPR may need to be continued during this period until the ECMO is fully functional. The use of the internal tube fixation component reduces the adverse effects of CPR on the ECMO internal tube.
[0077] Step 6: Once ECMO is effective and the patient's vital signs are stable, the use of CPR can be gradually reduced until it is completely stopped.
